How quickly it charges. How to charge your mobile device faster
The battery of mobile devices is a complex technical invention. Fitting 2 - 4 thousand mAh in a thin plate is the result of the work of hundreds of brilliant engineers. But the more complex the device, the easier it breaks and the harder it is to repair. Batteries quickly deteriorate if the device is not charged correctly. And then problems will begin with a little time battery life and even more dangerous things: the battery can swell and explode in your hands or pocket. How to use it correctly mobile device To avoid such problems, as well as about the features of charging a new smartphone or tablet, read our article.
Nickel-cadmium
Antique batteries dating back to 1899. They were not widely used, although they were durable and resistant to low and high temperatures (from -40 to +60 degrees Celsius). Withstood up to 2 thousand charge/discharge cycles.
Of the minuses: cadmium toxicity; high cost; “memory effect”, due to which the battery capacity decreases if you charge a not completely discharged battery.
Nickel metal hydride
A much more popular filling for old, cheap phones. Inexpensive, non-toxic (as it does not contain cadmium), capacious. However, it is quite large and heavy, and has a memory effect, although not so problematic.
Lithium-ion
Lithium-ion batteries are used in modern devices. They are more expensive than nickel ones, and are more capricious to temperature conditions (it is undesirable to use them at temperatures below -20 degrees Celsius). However, they are compact, capacious, do not require special maintenance, and do not have a pronounced memory effect.
Unlike nickel ones, they deteriorate from prolonged exposure to a discharged state. They also require constant calibration and charge/discharge cycles. And yet they are more convenient than nickel ones, which is why they are used everywhere.
Lithium polymer
Improvement of the above-described lithium-ion. They have all the advantages of ionic electrolytes, but polymer electrolytes make it possible to create plastic batteries various shapes and sizes. Today they are used in curved smartphones and are tested for possible use in flexible devices.
How to charge a new smartphone or tablet
The device that you just purchased and turned on was lying in the warehouse for several months before. So the battery, figuratively speaking, has not yet “warmed up”. To “stretch” the battery, you need to do three complete charge/discharge cycles. Drain the battery charge to zero, then charge it to one hundred, then again, and again. This will ensure the battery is properly calibrated.
One more nuance: it is advisable to discharge your phone or tablet on the first day after turning it on, without letting it sit for a week at 50 percent. So turn on some power-hungry application and leave it to eat up your charge.
- For everyday use, do not allow the device to completely discharge. And charge up to one hundred percent too. It is advisable to connect your phone or tablet to the power supply at 20 and charge it up to 80–90. Permanent job at extreme values (100 and 0) it has a bad effect on the battery;
- However, once a month it is advisable to perform such a complete discharge/charge cycle. During this cycle, the batteries are calibrated, which is necessary for the battery to function properly.
- It is best not to leave the device with the cable connected to the network. Although manufacturers have made sure that no more energy goes into the device than is necessary, this harms the battery.
- Overheating is very harmful. If your smartphone or tablet heats up too much and often, you need to figure out why this is happening. There is a table that shows how many percent of capacity the battery loses at different degrees of overheating. At 100% charge and a battery temperature of 60°C, about 40% of the capacity is lost per year.
- If you do not use the device for a long time, turn it off. It is better for the battery not to work at all than to work a little. However, turn it on from time to time to drain it and charge it to maximum. Calibration is required even if you are not using the device.
- To recharge the system faster, turn it off while charging. Processes will not consume resources, and the device will charge a little faster.

What ports can be used to charge devices?
You can charge your smartphone or tablet not only through the power cable from the outlet.
Any Android device can be charged using a USB cable from a computer or laptop. In addition, the chargers themselves in new mobile devices are attached to the USB cable as an adapter. It is enough to directly connect the USB cable to the computer’s USB port, and the microUSB to the device, and the charging process will begin.
You can also charge the device through the car's cigarette lighter. It is enough to buy an adapter. Some devices even come with such an adapter.
As for non-original chargers: this is quite dangerous. Even if your friend also has Android, and even if your phones are made by the same manufacturer, it is not recommended to use your friend’s charger. It’s at least worth looking at the parameters of your charger from the kit: voltage and current for which it is designed mobile phone. Don't take risks if the number of volts and amps varies too much.
The same applies to charging your tablet/phone. Of course, the ports are the same and the charging principle for smartphones and tablets is the same, so one charger will do. But make sure the charging socket parameters are the same, and use at your own risk.
Which ports definitely cannot charge the device?
There are myths that you can charge your phone through the headphone jack or HDMI port. All these are stupid inventions of people who do not understand the basics of physics and electrical engineering. Connector 3.5 mm Jack ( standard port for headphones) looks similar to some charging connectors, and perhaps the myth originated from there. However, the port is intended for audio streams and is not connected to the battery in any way, so you won’t be able to charge the phone through the headphones.
The same applies to HDMI. The port is not designed for this. You can charge the device either through a special charging connector or via a USB port.
Is it possible to speed up Android charging?
Fast charging function
Some manufacturers motherboards for computers and laptops, they add a fast charging function to their products.
When charging from a computer, only 0.5 A is supplied to the device. The accelerated charging function allows you to send a charge with more high strength current at 1–1.2 A.
Such technology is available, for example, in system Asus boards. To enable the function, you need to download and install the proprietary AiCharger application on your computer. In the program you need to check Enable under the inscription 3x Speed. And then click Auto Tuning. To disable the function, just select Disable.
AiCharger increases the current in the USB port from 0.5 A to 1–1.2 A
Many motherboard manufacturers have a similar application; more details need to be clarified for a specific model.
Battery Upgrade
A worn-out battery not only has less capacity, but also takes a little longer to charge. And if you notice that the device is taking longer to charge than expected, you should replace the battery.
Replacing the charging cable
Likewise, the charging speed depends on the cable. Frayed wires can interfere with charging, so it’s worth updating not only the battery, but also the power cable. Just be careful: it is recommended to buy only chargers from the device manufacturer that are designed for your specific model. A discrepancy between the calculated current and voltage can lead to disastrous results.
Some charging cable manufacturers offer to buy transformers with a higher current rating so that the device charges faster. This does work, but keep in mind that it is the magnitude of the current (and not the voltage in volts, as is commonly believed) that determines whether a person will survive an electric shock or not. Decide for yourself if it's worth it high speed charging.
It is important to know and apply the rules for charging mobile devices. Without proper care, smartphones and tablets lose a lot of battery life and charging speed. It is also very important to understand that using a non-native charger for a smartphone (especially one that you bought from an unknown manufacturer) is extremely dangerous. The power plug of smartphones acts as a transformer, when passing through it electric current reduces voltage and current. If the transformer is not doing its job, it becomes too risky to use the phone while charging. So it is best to use only chargers from the official manufacturer.
Everyone has found themselves in a situation where they need to quickly charge their smartphone. For an urgent call, before boarding a plane or in a foreign city - unforeseen situations can be different.
Many manufacturers are in pursuit of slim body save on battery capacity. We have to charge our devices every day, because in the modern rhythm of life we never let go of our gadgets for a second.
There are several ways to speed up the battery charging process, but not all of them are safe.
Turn off everything unnecessary
When the phone is turned on, the lion's share of battery energy is spent supporting the display, applications, background, processor, Wi-Fi, Bluetooth, GPS and LTE. Common sense dictates that it is better to charge the gadget when it is turned off. Another option is to disable functions that waste incoming charge:
- switch the device to flight mode;
- close all background applications;
- block;
- Do not use your smartphone until it is charged.
These methods have a significant drawback - you will not be able to receive or make calls when the phone is turned off or switched to airplane mode.
If you need to stay connected while the battery replenishes depleted resources, try not to touch the device. Endless updates pages, browsing the news feed and chatting with friends will significantly slow down the process.
Outlet or USB port?
If you're used to charging Android only from a computer, don't be surprised that the battery indicator is so slow to gain percentages - the USB port provides a charging current of about 500 mAh, sometimes even less. Don’t be lazy to take with you an adapter to connect the cable to the outlet: it is compact and lightweight, but it significantly speeds up the charging process.
Tip: If you cannot avoid using the USB port for charging, cancel the synchronization process when connecting the device to the laptop. Don't forget to make sure your computer doesn't fall asleep - some models stop supplying power to the USB ports in sleep mode.
Weather in the house
Everyone has noticed that in the cold any gadget quickly runs out of charge - it needs more energy to maintain functionality. The smartphone and its battery feel best at room temperature. Overheating and hypothermia slow down the charging process, so do not charge the device in a cold room or in direct sunlight.
Is more powerful better?
If you are not satisfied with the charging speed of a standard adapter, you may be tempted to replace it with a more powerful one. But this is unlikely to benefit the gadget and the battery: the manufacturer equips the device with a charger of optimal power, providing the necessary (and safe) current. Using a more powerful non-original adapter may harm your smartphone and reduce battery life.
The main thing is care
Experts say that to extend the life of the power source, you need to bring the battery charge to 100% once a month and then discharge it until the device turns off.
We have talked about battery life several times and have touched on, it seems, all the important topics: reasons for smartphones, tips on how to use them, and even. Be sure to check out our materials - there is a lot of interesting and useful stuff there.
In order to increase the battery life of Android gadgets, manufacturers are forced to increase the battery capacity. But at the same time the charging time Android devices becomes longer. And the question is becoming more and more urgent - how to enable fast charging and check whether it supports this function your device?

What is Quick Charge?
A phone that goes off at the wrong time is the cause of a bad mood for almost everyone. modern man. There are several ways to “reanimate” a phone. This is an adapter for a battery, a powerbank, or an adapter with a function Quick Charge. Let's look at Quick Charge in more detail.
Quick Charge is modern development from Qualcomm, which pioneered fast charging standards. This technology works by increasing the current supplied to the battery from the power supply.
There are already three Quick Charge updates:
- Quick Charge 2.0. The battery is charged to 50% in approximately 30 minutes
- Quick Charge 3.0. The battery charges to 80% in about 35 minutes
- Quick Charge 4.0. According to research, it is more effective previous version by 20% and almost does not heat the case. The current voltage is selected individually for each gadget and charging period
Most of the technology is in the power supply, and the processor is responsible for controlling current and voltage.
Fast charging function
The main function of Quick Charge is to recognize the current state of the battery and properly regulate the power supply of the gadget. Thanks to this, charging from 0 to 60% will be much faster than from 60 to 100%. This makes it possible to charge the device from 0 to 50% in 30 minutes. Proper power regulation will not allow high voltage and current will harm the battery.
How to enable fast charging
When purchasing a new smartphone, many users begin to understand it and wonder how to enable fast charging. In order to quickly charge the device, you need a smartphone itself that supports this function, powerful block power supply, which also supports accelerated charging and USB cable. No additional measures are needed. The function itself is activated during charging, provided that the device supports Quick Charge.
On at the moment There are already quite a few smartphones that support this function. Namely: Xiaomi Mi6, Xiaomi Mi Max, HTC 10, Meizu MX6, LG G6, Moto X Force, Galaxy S8 and so on. More full list can be viewed on the Qualcomm website.
How to disable fast charging
Quick Charge is a great feature that allows you to charge your phone many times faster. But there is one negative point in it, which poses a significant threat. This is heating of the body and insides of the gadget, which can cause permanent damage.
Not all devices have the option to disable fast charging. Some firmwares have it. To check for this feature, go to the battery settings menu. If you cannot disable the function programmatically, then there are two options for resolving the issue:
- change
- buy a less powerful charger
If you enable fast charging, what's the harm?
It has long been no secret that slower charging is more gentle on the battery than fast charging. A side effect of fast charging is that the case heats up. High temperature almost always has a bad effect on any electronic devices. And yet, at the moment there is no absolute evidence that frequent use of fast charging Quick Charge negatively affects the performance of the battery and the device as a whole.
The average lifespan of a smartphone is about 1.5-2 years. During this time, the user will not have time to exhaust all battery resources. The wear and tear will be the same as using a conventional charger.

Answers to questions
Fast charging does not work. What could be the reason?
Make sure your device and power adapter support Quick function Charge. Also, the malfunction of the function is affected by a possible breakdown of the smartphone, adapter or USB cable.
Android smartphones are becoming bigger and better almost every day, the number of available functions is increasing, screen resolution is growing, cameras are getting bigger, and so on. But the obvious trend is to make new smartphones thinner. Because of all of the above, the smartphone battery is quite active work will require recharging. So, below are some tips that will allow you to learn a little more - you will be able to charge Android smartphone faster and also reduce recharging time.
Note: These tips can be used with Galaxy S4/S5, HTC One, Moto X, Nexus smartphones and tablets, LG G2/G3, Samsung Note 2 and 3, Galaxy Grand and other new models.
Set your smartphone to charge with Airplane Mode turned on:
When Airplane mode is turned on, you will save up to 30% of the waiting time before recharging ends, since the phone itself will not waste charge on mobile communications, Wi-Fi networks, which requires a lot of energy. However, you will not be able to receive calls, SMS or use the Internet.
Turn off the device while charging:
Turning off the device while charging will greatly reduce the charging time. This is even more effective than turning on the Airplane mode, since the display is also turned off, everything background processes, however, when the smartphone is turned on, we can monitor the charging percentage, whereas when the device is turned off, we just have to wait for charging to finish, but there is no way to check whether the process is complete.
Do not delay the process of recharging your smartphone:
If you charge your smartphone even after the charging process has completed to 100%, your battery will slightly lose capacity. I don’t recommend charging your smartphone for those who like to plug it in and go to bed.
Do it once a month complete discharge batteries:
Once a month, it is advisable for you to completely discharge the battery of your smartphone to zero and then full charge. This will allow you to “calibrate” the battery. This is only relevant for lithium-ion batteries.
Use only original charger:
Using an original charger will help maintain the health of your battery, since the charging and battery characteristics are the same (regarding voltage). If you use others chargers, then the voltage may be different and this greatly affects the battery life, and it also changes the charging time of your phone or tablet.
Do not charge your smartphone via USB:
Charging when connected to USB port The computer will never be able to provide the required current, which is only available with the original charger. This significantly increases recharging time and also has a strong negative impact on the battery.
Any modern mobile device continues its vigorous activity even in the background. For update social networks, weather widgets, news, balance, exchange rates and other services consume a lot of energy. Of course, you can turn off all synchronization on your phone manually, but this will take time that you no longer have. But that's not all. The radio module of the smartphone constantly scans cellular network, which also takes a lot of battery resources. Yes, you can enable Airplane mode. Then all processes that used mobile network will stop working. However, there will still be many system processes that do not depend on the presence of communication. So what to do?
The solution is simple. You must completely turn off your smartphone/tablet and connect it to a power source. When turned off, the device will not waste energy, but only receive it. In other words, 100% of the charge entering the battery will remain in it. Charging time is significantly reduced.
On the contrary, when the device is turned on, it also receives 100% charge, but immediately about 50% is spent on maintaining system processes and other services. Therefore, in reality, the gadget only gets half a charge, which increases the charging time.
Let's return to our story. Immediately after your friend called, you turned off the phone and set it to charge, while you yourself began to get ready for the meeting. In half an hour you are completely ready. Unplug your phone from charging, press the power button and go put on your shoes. Then leave the house, close the door and look at the screen of your smartphone. Oh, miracle! It was charged 50-60%. When used sparingly, this is enough to call your friend several times and even order a taxi at the end of the evening.
