• Which smartphone battery capacity is better. Phone battery capacity - which is better? Through mobile applications

    The modern market is just teeming with a huge variety of smartphones that you can buy. Different price categories, colors, models of characteristics, with each new day there are more and more different designs and manufacturers. However, the most important feature that unites all models is battery power. Today we will talk about the battery capacity of the phone - which is better, and what nuances you should pay attention to when buying a new gadget. How many hours does the popular battery last? How to choose how many hours it lasts and what the phone battery is measured in.

    Technical feature of the power supply

    When buying a mobile device, each person thinks about what size phone battery is best, what kind of battery and why is one of the main characteristics of any gadget?

    Important! According to its design features, a smartphone is very similar to a tablet. The volume of the battery they can be the same, and therefore can be different. This is due to the fact that during operation our mobile device is used for cellular communication. That is why battery consumption is spent, first of all, on this nuance, and only then on Bluetooth, Wi-Fi and similar services.

    All of the above nuances include the fact that an increasing number of people are on social networks from a mobile device and regularly view the feed. As a result of the long operation of the screen, the Internet and cellular communications, which can work in data transfer mode, the consumption of the power source increases several times.

    Based on all the above facts, it is worth getting yourself a phone that is characterized by a good battery capacity for a smartphone.

    Choosing the best capacity for a smartphone

    In today's market, you will find mobile communication devices with different battery capacities. It should vary from 1.5 to 5000 milliamps.

    Important! This indicator is conditional. So, modern mobile devices can have a low battery capacity, but at the same time work very quickly. This is due to the fact that all models are equipped with powerful processes, and the software is perfectly optimized. When deciding which battery capacity is best for a smartphone, one must take into account the fact that even with a small indicator, autonomy can be large. However, this rule applies exclusively to expensive models.

    On the other hand, you need to look at gadgets with the Android operating system. The fact is that budget models are produced with such a base. As a result, the battery charge may run out in half a day, or at night the phone will turn off for some unknown reason, at first glance.

    In any case, regardless of the operating system, it is better to purchase models with the highest rate. It's pretty easy to decide:

    • If the box says that the power source contains 200-2500 mAh, then the gadget will be able to work for a day.
    • An indicator equal to 300-4000 mAh symbolizes that you will charge the gadget once every two days.
    • If you are thinking about buying a mobile device with a rate of 5000 milliamps, then you can charge the phone once every six to seven days.

    Important! Before you buy a modern gadget and think about which battery is best for a smartphone, you need to take into account the factor for which purpose you are purchasing it:

    • If you need to read a book and only talk on the phone, the minimum amount may be enough.
    • For constant listening to MP3 Player, games, watching movies, you should purchase devices with a battery capacity of at least 3000 - 4000 mAh (mah).

    Choosing the best smartphone by manufacturer:

    • Among a variety of manufacturers, a good battery capacity for a smartphone is from the manufacturer of the Samsung brand.
    • It should also be noted the excellent work of the Microsoft trademark. Please note that the volume indicators on these devices are true. So, if the volume is 2500 milliamps, then you will charge the gadget once every two to three days.
    • Models with good batteries include HTC, Lenovo, Asus, and Acer.

    Important! If you want to buy yourself a Chinese “fancy” phone, then take models that cost at least $200. Remember that you can count on high-quality components only if the manufacturer of the equipment has really proved itself worthy in the market. Therefore, looking closely at a new gadget in terms of battery characteristics, click on the link so that you no longer have any doubts about which manufacturer is better to choose a smartphone.

    How to reduce battery consumption?

    If you are still thinking about what battery capacity is best for a smartphone, then you should know what nuances the main battery charge is spent on.

    The main consumers of the charge:

    • display;
    • data transfer;
    • cellular.

    Tips for reducing battery consumption on modern models:

    • Turn on data transfer only when you need to. Turn off after use.
    • Reduce display brightness.
    • Delete unused apps. It can be either open at the moment or downloaded, but rarely used.
    • Turn off your phone at night or use the Airplane feature.
    • Turn on battery saver when your phone is set to allow it.

    Also on our portal you will find many useful tips on how to increase phone battery life.

    Extending battery life

    Despite the fact that we figured out the battery issue, you need to monitor the charge and extend its life.

    • You need to charge up to 100%.
    • Don't waste your battery. Connect the charger to it when the energy indicator is 40-50%.
    • In no case do not put the phone plugged into the mains at night.
    • As soon as the phone reported a full charge, unplug it.
    • Use only original chargers.
    • Do not charge phones and put them near heaters, heating elements and under the influence of sunlight. All devices do not like high temperatures.
    • Once a month, to prevent the controller, it is worth completely discharging the battery and charging it up to 100%.

    Important! Separately, read about how to properly charge your smartphone so that its battery lasts longer.

    footage

    Over time, especially with heavy use or frequent full discharge, the battery on an Android phone loses its capacity, and when replacing the battery with a new one, you can very often get a lower capacity than the factory battery, even if the sticker shows the same numbers. In all these and many other cases, it can be useful to know the real capacity of the Android battery, which will be discussed in this guide. Also useful: , .

    Unfortunately, there are no built-in functions for assessing the current battery capacity on Android: some manufacturers have built-in applications or sections in the settings for assessing the “health” of the battery, but it is not always possible to draw correct conclusions from them. There is also no system information about the actual capacity that could be used in Android. However, data on power consumption at any given time (which the system provides) and information on the remaining charge allow third-party applications to analyze and calculate close to the actual capacity of the installed battery.

    Finally, some additional information that you may find useful:

    • When you change the battery in the workshop or purchase (especially from comrades from China) and install it yourself, the words "original" and pleasant numbers like "4000 mAh" are often far from the truth.
    • Many sites like the one you're on now offer instructions on "How to calibrate an Android battery" that boils down to a full charge (sometimes with some nuance) and then a full battery drain and reports that this will allow the phone " evaluate" and more accurately show the percentage of charge or increase the capacity. The first, with some reservations, is to some extent true: a full charge / discharge cycle performed from time to time (once a month or three) allows a special chip on the battery to further transmit more accurate charge percentage numbers, which, in turn, shows you the phone. However: even if you decide to do this, and saw the advice that this cycle is worth doing some times in a row on a new phone or a new battery, I strongly recommend not to listen. The second is completely false today, unless your phone has a NiMh/NiCd battery installed (theoretically it is possible, but only on very old devices, I have not seen such in recent years).
    • If your phone suddenly turns off or instantly discharges after reaching a certain percentage of charge (50%-30%), this usually does not indicate calibration problems, as described in the previous paragraph, but is related to the first paragraph (in the case of a relatively new battery) or or with severe wear/damage to the battery.
    • If you are interested in dealing with truth and fiction on the topic of modern batteries and the features of their work, and you are also ready for the fact that it will not be in Russian (but very understandable for beginners), a better resource than https://batteryuniversity.com/ learn/ , perhaps not to be found.
    • In a well-known Chinese online store, you can find inexpensive hardware battery capacity meters by searching for phone battery meter.

    Universal external batteries, or power banks, are not such a complicated technique that you can get confused in them. We will tell you how to choose an external battery for your phone - which one will best be able to power your devices even on a long trip.

    How to choose an external battery for a smartphone? Main characteristics

    Capacity

    The main parameter by which you should choose an external battery is, of course, its volume. It depends on it how long it can power your devices. Modern power banks have a capacity of 2,000 to 50,000 mAh. But the principle “a lot means good” does not work here: with an increase in capacity, the size and weight of the battery increase.

    The most comfortable for daily wear will be a battery with a capacity of 5000 - 10,000 mAh - this is if you want to charge only one device and do not go far from home. If you need an independent power source for several devices, or you plan to be away from the outlet for a long time, it is better to pay attention to external batteries with a capacity of 20,000 - 30,000 mAh.

    Charging current

    The second important characteristic is what current the device is capable of producing at the output. The higher the current, the faster the battery will charge. But charging batteries too quickly is not entirely correct: they can overheat and fail faster. For an average smartphone, a device with a charge current of 1-2 A is enough, for tablets and laptops, 2-3 A is required.

    The optimal charging current can be "peeped" on the charger that comes with the gadget. As a rule, the electronics of the gadget limits the maximum current for safety reasons, so weak devices are unlikely to burn out from powerful charging -.

    The most successful option is a power bank with two ports that give different output current. For example, one port can deliver 1 A, the other 2 A - a couple of external batteries for a smartphone with such an opportunity, we will tell you at the end of the article.

    But most often, the manufacturer indicates the total current that the device can give out - that is, when two smartphones are connected, each is given 1 A, a total of 2 A. Keep this in mind!

    Ports and cables

    Devices are connected to the powerbank via USB ports using bundled cables and adapters. Take another look at your devices and ask yourself two questions:

    • Firstly, how many devices do you want to charge at the same time? The same number of ports, ideally, should be on an external battery.
    • Secondly, what devices do you have? If you have an iPhone, the power bank should have a Lightning connector, if you have an old iPhone, you will need an adapter from Apple 30-pin to USB. To connect other devices to an external battery, you may need USB to microUSB, USB Type-C adapter cables, or a DC-DC cable (for a laptop).

    Cables can be supplied with the power bank, but if necessary, they can, of course, be purchased separately. In addition, there are external batteries with attached sets of adapters, including those for peculiar connectors like the same Apple 30-pin.

    Charging type

    Important question - how do you intend to charge the power bank itself. A good external battery has a microUSB connector for self-charging. Accordingly, you can even charge it with a smartphone charger (keep in mind that with a small charging current, this will take a long time). You can also use any other connector - for example, a computer port, a USB socket or a car cigarette lighter.

    But there are alternative options - for example,. Then you can replenish energy reserves by simply leaving it in the sun for a few hours - and then charge your gadgets from it. For long hiking trips to nature, such a device will come in handy, and it will come in handy in the country. In addition, this is a minus one gadget that will draw energy from your outlet.

    Special requests

    The four characteristics mentioned above are common when choosing any power bank. However, besides this, there are many interesting additional options that an external battery for a smartphone can have - how to choose the right ones is up to you:

    • Charging laptops. Such a power bank can produce enough voltage to recharge the battery of your laptop. External batteries with this function are often equipped with DC inputs, as well as voltage switches that allow you to increase and decrease it: after all, a laptop needs a voltage of about 20 V to charge, and a smartphone “eats” only 5 V - the comparison here is clearly not in favor of the “laptop” . Of course, such devices are quite large.
    • fast charging. Powerbank can support fast charging functions: Qualcomm 2.0, 3.0 or 4.0, as well as proprietary technologies - Samsung FastCharging, Meizu mCharge, Asus BoostMaster. And both for devices and for yourself - in order to replenish your reserves as quickly as possible.
    • Wireless charger. Power banks with this feature have a transmitter that is supported by new smartphones. In order for the phone to start charging, it will be enough to put it on top of such a power bank - no cables are needed.
    • Protection against dust and moisture. Some powerbank designs have gone through and are rated up to and including IP68. Take an interest in this characteristic if you need a really secure external battery (perhaps for your super-secure smartphone,).
    • Information display. On it you can see the remaining charge in the power bank, the current voltage, current and other important information.

    In addition, a power bank can have a cute design and an unusual shape, be supplied with accessories - complete cables, adapters, a cover or a storage case, and some models can even be used as a flashlight.

    Xiaomi Mi Power Bank 2 10000

    Xiaomi's aluminum lithium polymer power bank is designed to charge one device at a maximum current of 2.4A, while supporting Qualcomm Quick Charge 2.0. Two USB connectors allow you to charge the device and the power bank itself, which will take only 4 hours to replenish its reserves. The device weighs only 228 grams and easily fits in your pocket.

    Xiaomi Mi Power Bank Pro 10000

    Another model from Xiaomi, very similar to the first one, but with a USB Type-C connector and a USB-C adapter included. In addition, a newer version of Quick Charge 3.0 is supported, thanks to which the power bank is fully charged in 3 hours. The maximum output current of the device is 2A.

    ASUS ZenPower 10050 mAh ABTU005

    Asus' multi-colored rubberized power bank has a capacity of 10,050 mAh and is equipped with standard USB and microUSB connectors for charging one gadget and the power bank itself. By the way, it takes about 8 hours to fully charge, as Quick Charge functions are not supported. But the device is very light (215 g) and resistant to shock.

    How to measure smartphone battery capacity © news.usc.edu

    When buying a phone, especially a Chinese one, many people want to know how much the real capacity of its battery corresponds to the declared one. Many also want to know how worn out the battery of their smartphone is after a certain period of use. Especially often such a desire arises if the device starts to hold a charge noticeably worse than after purchase.

    You can check the battery capacity of your phone in several ways, both software and hardware. The former are more convenient, since they only require installation of the application and testing in it. However, checking the battery at the hardware level, using special equipment, is sometimes more accurate.

    What is the correct way to measure battery capacity

    It’s worth starting with determining the units in which it is correct to measure the battery capacity. Many consider milliamp-hours (mAh) to be such, which is not entirely true. Only the relative difference in capacity between two batteries of the same type and voltage can be measured in mAh.

    The fact is that electrical power is calculated by multiplying the operating voltage (volts) by the operating current (amperes). The unit of measure for this power is watts. The amount of energy is the power that can be delivered over a period of time (hours). Accordingly, when measuring it, hours are added to volts and amperes. The correct unit of measure for battery capacity is watt-hours (Wh).

    Watt-hour capacity is the electrical power that a battery can deliver for an hour. Accordingly, a volume of 10 Wh indicates that when a power of 10 W is output, the battery will last exactly an hour, and if the load is reduced to 5 W - 2 hours, 1 W - 10 hours. The voltage and current strength of the compared batteries do not matter, since the watt-hour is an independent, absolute unit.

    When measuring battery capacity in mAh, we only consider current (milliamps) and not voltage (volts). If two batteries, 2000 mAh and 4000 mAh, have the same voltage, then the second is exactly twice as large as the first. But if the first produces 4 volts (lithium-ion), and the second only 2 (lead-acid, 1 cell), then the batteries will be the same. After all, if you multiply 2000 mAh (2 Ah) by 4 volts - there will be 8000 milliwatt-hours (8 Wh), and if you multiply 4000 mAh by 2 volts - in the end there will also be 8000 mWh.

    Due to the fact that ampere-hours, without taking into account the voltage at a particular point in time, do not allow you to determine the amount of energy, you should not evaluate the volume of the phone's battery by the mAh that the USB tester produces.

    The average smartphone lithium battery voltage is just under 4 volts, and the mAh rating in the specifications is indicated for it. Charging the phone is usually done with a voltage of 5 volts (from 5 to 12 with support for fast charging). Therefore, if during charging from 0 to 100% the device showed 3000 mAh, and the charging efficiency was about 100%, then 15 Wh of energy was poured into the battery.

    With the battery voltage dropping to 3.8 volts, this means that the battery capacity in manufacturer's units is about 3.94 Ah or 3940 mAh (15 Wh divided by 3.8 volts). So do not rush to blame the Chinese, as if they "did not top up" milliamp hours if the device shows less than it should be.

    How to check phone battery capacity with USB tester

    As mentioned above, The easiest way to check your phone's battery capacity is to use a USB tester..

    USB Safety Tester J7-T

    On the one hand, such a device contains a USB plug, which is inserted into the power supply, on the other, a USB socket, into which the smartphone is connected with a cable. Also, the device contains a screen on which the test indicators are displayed.

    There are many varieties of USB testers: from simple ones for a couple of dollars, which can only show volts, amperes and count mAh - to advanced professional ones ten times more expensive. The latter are often equipped with color screens, can count watt-hours in finished form, support fast charging, take into account efficiency, can be synchronized with a PC for plotting, etc. To simply check the battery capacity of the phone, a simple device, like the one in the illustration, is enough.

    To take measurements - discharge the smartphone "to zero". Then connect the tester to the charger, connect your device to the tester with a cable, and leave it to charge up to 100%. When the battery is charged, the tester will show how much energy is poured into it.

    If the device can show watt-hours, this is the amount of energy. To convert it to mAh, divide the resulting number by the voltage of 3.8 volts, and multiply by about 0.9 (since the efficiency rarely exceeds 90%). That is, if the device shows 10 watt-hours (10 Wh), then (10 / 3.8) * 0.9 \u003d 2.37 Ah or 2370 mAh is the volume of the battery. If the capacity declared in the characteristics of the smartphone is 2500 mAh, then the battery wear is about 5%.

    If the USB tester measures only mAh, then you need to make a correction for the voltage difference. To do this, first multiply the number of mAh by 5 (volts), and then the result (it will be milliwatt-hours) is divided by 3.8 and multiplied by 0.9.

    With the tester readings of 4669 mAh, the battery capacity of the smartphone will be 4669 * 5 = 23345 mWh, (23345 / 3.8) * 0.9 = 5529 mAh. That is, although the device indicated only 4669 mAh, the battery capacity of the phone in the units indicated in the specifications is about 5529 mAh.

    How to measure phone battery capacity programmatically

    If you do not have a tester, you can measure the battery capacity of your smartphone using special applications. One of the best options for this is AccuBattery. The free version of the program has wide functionality and can calculate battery performance parameters. You can download it on Google Play.

    For testing, install the program on your smartphone, and then discharge it until it turns off. Charge your device, turn it on and launch the app. In the "Charging" tab at the bottom, set the design capacity indicated by the manufacturer if it is not displayed correctly. Leave the device to charge, preferably up to 100%.

    When the smartphone is charged, you can go to the “Health” tab in the program. It displays the current capacity indicator, calculated based on data built into the charge controller in the phone. The program automatically calculates the degree of battery wear and shows it.

    If you keep AccuBattery in the background all the time, the app can generate wear graphs so you can determine how quickly your phone's battery is degrading.

    The downside of AccuBattery, like any analogue, is a big dependence on the accuracy of the smartphone's on-board sensors. After all, the calculations are based on the indicators of the voltmeter and ammeter built into the charge controller. If these sensors are inaccurate, distort information, then the final indicators will be incorrect.

    Worst of all, software methods work (more precisely, they don’t work) with cheap Chinese smartphones from the price range of about $100. Such devices, in order to reduce the cost, often deprive full-fledged sensors. If they are (and any battery controller on the smartphone board can measure voltage and current), then there is no access to these sensors from the operating system. In this case, the program will not be able to measure the battery capacity of the phone.

    In addition to testers and programs, there are more accurate ways to measure battery capacity. There are full-fledged testers for taking measurements on batteries disconnected from the smartphone. These are often used for tests, for example, round batteries of 18650, 14500 formats and the like.

    LiitoKala Lii-500

    By measuring with the battery disconnected from the smartphone, you will get the most accurate capacity readings. But since 90% of modern mobile phones are equipped with non-removable batteries that use a cable instead of a contact pad for connection (as it used to be), this method of measuring capacity is not applicable to them.

    You take out your phone to make a call or use the GPS, and suddenly you see the message “Battery low”. Familiar situation, right?

    Batteries in phones - once and today

    Remember the need to "format" the battery? Discharging your phone three times before completely shutting down and then charging for 12 hours? This was very important for nickel cadmium (Ni-Cd) and nickel metal hydride (Ni-MH) batteries.

    This behavior was supposed to protect them from the “memory effect” and the “lazy battery effect”. Both problems were to reduce the capacity of the battery while maintaining a real reserve. lazy battery effect was reversible and caused less performance loss. The battery could be fixed by connecting it to a special charger with a discharge function. memory effect causing more problems because it forced you to replace the battery with a new one.

    Then they began to use lithium-ion batteries (Li-Ion), which are still popular today. You will find them in most smartphones available, as well as in many other devices: laptops, tablets, e-book readers. Their main advantages are: fast charging, long service life, higher performance and smaller size.

    The most efficient type of battery, which is increasingly found in smartphones and other electronic devices, is currently lithium polymer (Li-Poly) batteries. They are very roomy and charge much faster than standard Li-Ions. In this regard, manufacturers willingly install them in flagship smartphone models.

    ma*h is the unit in which the capacity of the battery is indicated? It means the amount of energy that the device will absorb in 1 hour. In other words, a capacity of, for example, 3000 mAh means that within an hour your smartphone will absorb 3000 milliamps.

    What parameters determine battery endurance

    The number of matches is only one of the elements. The operating time of the phone is also affected by its other features. If you need a smartphone with a reliable battery, pay attention not only to the battery capacity of the model, but also to the screen size. It is the ratio of these two values ​​that will tell more about the subsequent battery life in this model - due to the fact that the screen consumes the most power.

    An important issue is also the performance of the central processor. Mid-range components tend to use less power. However, it is worth knowing that the latest mobile processors with high performance also manage energy better thanks to appropriate optimization.

    How to increase battery life

    Formatting a Li-Ion and Li-Poly Battery

    Batteries currently in use do not require formatting. In the case of Li-ion and Li-polymer, partial charging works much better - for example, from 40 to 80%. Try also to avoid a complete discharge.

    Our following tips will help you with this:

    Screen backlight

    The screen consumes the most energy. You should decrease its brightness. A lower backlight level will significantly reduce battery consumption. Most smartphones also have a built-in light sensor that automatically adjusts the brightness of the display according to lighting conditions, which is supposed to save energy.

    However, remember that too frequent changes in the backlight level in some smartphones, on the contrary, can drain the battery even faster. It is worth checking how this feature works on your smartphone.

    Auto-rotate screen

    If your smartphone's battery doesn't last all day, consider turning off the auto-rotate screen feature.

    Changing the orientation drains the battery because the phone uses the accelerometer to determine the position. If you turn it off, you will reduce the use of this sensor and energy consumption.

    Widgets

    Allows you to quickly access frequently used functions, but consumes more power. This is because they require frequent updates. You should limit their number, or use widgets with a manual update function.

    Screen Timeout

    Screen automatically turns off after 15-30 seconds. The less you work, the more energy you save. Reducing the display timeout will allow you to noticeably increase the operating time of your phone.

    Standby mode

    The standby mode itself also consumes a lot of energy. The phone does not work, but is ready to start at any moment. Questions often appear on the Internet on how to turn off standby mode. This cannot be done! But you can stop applications running in the background, displaying notifications, using Wi-Fi and determining the location.

    If you care about saving battery power, switch your phone to flight mode (offline mode), in which all networks are turned off, you cannot receive calls, sms and notifications from the application. Thanks to this, you save the charge of your smartphone.

    Automatic synchronization

    Thanks to it, you do not have to check every time if there are new messages in your mailbox or update the widget with the weather forecast. However, this requires a systematic connection to the Internet and checking email. You can disable this feature altogether.

    Another way is to reduce the clock frequency. You will find this option in the phone system (or in the settings of each application).

    Data transfer

    Another point is to turn off data transfer (over a cellular network or Wi-Fi), as well as other communication options (Bluetooth, NFC) when you are not using them. You can also select the desired network type (2G or 3G) in the mobile network settings (Settings - Mobile Networks), instead of switching between 2G / 3G / 4G automatically. In this way, you will avoid frequent network searches, which also consume the battery.

    On some smartphones, you can also choose which applications can use the connection. Limiting their number will certainly help save energy.

    Also remember to turn off automatic updates. Much better to do it manually when you get a notification. Don't ditch it entirely - new versions of apps can be much better optimized for battery usage.

    Remove also unused programs. Otherwise, the system launches them and they run in the background. If you can't remove them, use the Disable option. You can find it in the menu when you hold the app icon or in your smartphone settings.

    Games can consume a lot of power, especially those that require active location, data transfer, and an always-on display. If the battery in your phone leaves much to be desired, you should stop using such demanding games, or...

    Buy Power Bank

    This is a compact device that will provide your smartphone with an additional charge of energy. Some PowerBanks are keychain-sized gadgets that fit easily into your pocket. Particularly popular are devices with a volume of 8400 to 10050 mAh, which allow you to perform several recharging cycles.

    Save energy with a task manager

    Android has a lot of apps running in the background so they can launch quickly. This results in additional energy consumption. Some people recommend using a task manager (so-called "task killer"), which kills the application in the background, saves memory, and as a result, saves battery power.

    In practice, it looks a little different. The Android system is designed to make efficient use of RAM. There, it stores some of the applications in order to turn them on faster, consuming fewer resources than when loading from scratch. The task killer will disable the application completely, which means that restarting it will require more resources and energy.

    The second question is that the Android operating system may try to restore the application, which also consumes the battery. In addition, remember that Android closes applications that have not been used for a long time, which saves RAM and battery. For normal use, this is sufficient.

    The same is true for the iPhone and the iOS platform. Most applications running in the background are not actually running ("frozen") and do not consume power. Much more energy will be required to start programs from scratch.

    Applications to extend battery life

    There are many applications on the market that allow you to monitor the battery status of your phone and save energy. See which are worth looking into.

    Fast battery charging

    Manufacturers offer more and more smartphones with Quick Charge (also known as Super Charge or Turbo Power), which allows you to fully charge the battery within a few tens of minutes. All you need is a phone and charger that support this technology.

    This is a very useful solution if you lead a very active lifestyle and are often away from a power source. If you forget to connect your smartphone to the charger at night, you will have time to charge it in the morning, even just before going out.

    Just a few minutes is enough to charge the battery to a level that will last for another 8-9 hours of operation.

    The multitude of features combined with the large screen is a big challenge for the phone's battery. We hope that our advice will help you in increasing its service life.

    And what methods do you use to extend the battery life of your smartphone? Share with us. We look forward to your comments.
