Articles and Lifehacks

Each of us is familiar with the problem of a low phone battery. After all, no power means no phone. Therefore, when choosing a phone, it is very important to know the characteristics of the battery, because it depends on which battery is better how long you will be in touch, be able to listen to music or just play games and use the Internet.

There are two important criteria, about which you should ask the seller first of all: type and capacity. There are still some nuances that should be taken into account when purchasing, and among them are the power consumption of the phone and how often and for what, besides talking, you will use your mobile phone. Let's look at the types of batteries in phones.

Pros and cons of different types of phone batteries

But, along with this, there are very noticeable disadvantages - large size mobile phone and one very unpleasant need to completely discharge the battery from time to time so that later when charging it can be charged again full power. In addition, this type of battery requires long time for charging.

Typically, such batteries are used for cheap mobile phones with a basic set of functions, and if you are not particularly concerned appearance your mobile phone, then this option may well suit you.

Li-ion Lithium-ion batteries are very popular and are used in modern mobile phones, although they are more expensive than nickel-metal hydride batteries because they have undeniable advantages, among which are compactness, low weight and at the same time - high density energy. In addition, this type of battery the better, which does not require any additional maintenance like a complete discharge.

Li-Pol. Lithium polymer batteries are a new stage in the development of lithium technologies. , such batteries were not even thought about. Probably the biggest advantage of these batteries is that their production technology makes it possible to produce batteries different forms and volumes. They can be very thin and compact. The cost will also please you - it is lower than the cost lithium-ion batteries, and with all these advantages, such batteries have high energy capacity. This type batteries used for the line of phones from .

An external phone battery allows you to charge your phone and other devices without even having a power outlet nearby.

Compact Power Bank is an innovative gadget that can recharge all user phones “on the go.”

Batteries differ according to three main criteria:

1. According to its capacity;
2. By type of outgoing current;
3. According to the type of battery itself.

Mostly all external chargers made of plastic. More expensive options are made of metal and a waterproof surface.

However, such batteries are more intended for hiking conditions than for everyday use. For an ordinary user, a plastic Power Bank will be enough.

There are also external chargers for certain smartphone models. They are attached to the phone body.

The disadvantage of such batteries is that they are not universal, and their cost is several times higher than the cost of a good Power Bank, which can charge several user phones at once.

In most cases, batteries must be selected based on such a parameter as capacity. A good external battery for a smartphone should have a capacity of at least 2500 mAh.

For a tablet, an external battery must have a capacity of 5000 mAh. Such minimum requirements The containers will allow you to fully charge the gadget at least once.

The current supplied by the smartphone also affects the choice of battery. Basically, all smartphones transmit a current of 1 or 2 Amps.

On the charger that comes with your smartphone, you can read the required voltage that the charger should have.

How to charge a smartphone? To do this, simply connect your phone to an external charger using a USB cable.

The charging process will start automatically. The Power Bank itself needs to be recharged periodically. It is charged from an outlet.

Let's take a closer look at individual models of external batteries for smartphones.

Choosing an external battery for your phone

Most users of modern smartphones face a problem fast discharge battery of your smartphone. Very often the battery dies at very inopportune moments and even during a conversation. At this moment it is not at hand electrical outlet and power adapter. The batteries of the vast majority of phones on the market are capable of operating offline mode approximately 2-3 days. And this is if you only call and send messages. If you start watching videos on your phone, surfing the Internet, chatting with friends or playing games, the battery charge literally melts before your eyes. Modern models phones with powerful CPUs and huge displays will not last even a day in this mode. The obvious and most quick solution The problem of discharge is the purchase of an external battery for the phone. Such devices are often called power banks and can be used to charge smartphones, tablets, players, and laptops. Today we will talk about the features of choosing an external battery for your phone.

In retail stores and on virtual shelves on the Internet, users will find a huge number of models of external rechargeable batteries for smartphones, tablets and other mobile equipment. The price range is simply amazing. No wonder that regular user gets lost in all this diversity and begins to compare power banks only by capacity and design. As a result, they choose the model of external battery that they like best visually.

And buyers often don’t see beyond the appearance technical characteristics devices. This is completely unacceptable, because in the future, when using an external battery, you will be faced with the fact that the model simply does not suit your needs. Of course, you need to pay attention to design, but not in the first place. You need to choose a power bank according to the characteristics that are discussed below.

Capacity

One of the main characteristics of an external battery. When choosing a capacity, you can rely on one rule that was developed as a result of long-term use of a power bank. It is as follows. The size of the external capacity battery should be twice the capacity of the phone battery. And you don’t need to think that the double capacity of the power bank will allow you to charge your phone’s battery 2 times on the road. What's the catch here?

The problem is that external batteries usually contain lithium batteries with a nominal voltage of 3.7 volts. Charging your phone battery requires approximately 5 volts. For this purpose, such devices have a voltage-increasing circuit. This results in capacity losses reaching the level of 30-50%. So, when buying an external battery, focus on a capacity twice as large as the gadget’s battery.

When you choose the capacity of an external battery, immediately decide which devices you will charge with its help. The most common options:

• The power bank charges the phone and some other gadgets with a low-capacity battery;
• An external battery is used to charge a phone, audio player, tablet, camera, etc.;
• Laptops and netbooks are charged, as well as other devices with large capacity batteries.

If you will use an external battery only to charge your smartphone, buy a model with a capacity of 5000 to 7000 mAh. Modern phone models are mostly equipped with 1800-2500 mAh batteries. Therefore, the specified power bank will be enough for them for 2 full charges. External batteries with a capacity of up to 7000-8000 mAh are compact and weigh very little. Therefore, there will be no problems wearing them. Such devices fit into a jacket pocket and have a USB port with a charging current of 1 ampere. This is enough for a phone.

If you need to charge not only your phone, but also your tablet, then you should look towards universal external batteries with a capacity of 10,000 to 16,000 mAh. It is important that such a power bank has 2 ports with different charging currents for a phone and a tablet. Smartphone and music player It will be possible to charge 1 ampere from the port, and 2 amperes for the tablet and camera. The dimensions and weight of such universal external batteries are quite noticeable. But you can always find a place for them in a diplomat or a woman’s handbag.

If an external battery will be used to charge a netbook or full-size laptop, you should choose a model with a capacity of 15,000 to 20,000 mAh or even more. Moreover, the USB port must provide a charging current of 2 amperes or more. Otherwise capacious battery The laptop will take an extremely long time to charge. Manufacturers often integrate external batteries for laptops into different external modules. This could be a docking station external keyboard etc.

Charging current

As for the main current requirements, they were named in the previous section. Let's summarize this information. In the list below you can see the charging current of the external battery port depending on the device being charged:

• Phone or player ─ 1 ampere;
• Tablet or camera – 2 amperes;
• Laptop or netbook – 2 amperes or more.

Dimensions and weight

The dimensions and weight of an external battery are largely determined by the battery capacity. When increasing the battery capacity, additional elements (batteries) are added to it. In order for them to fit into the case, manufacturers have to increase the dimensions and weight of the device.

For this reason, you must immediately decide on the list of devices that you will charge from an external battery. That is, if you are only going to charge your phone, then there is no reason to buy a universal high-capacity power bank model.

Additional Features

In addition to the main characteristics, when choosing an external battery for your phone, you should take into account a number of the following parameters:

• aesthetics. The design of the device should be pleasant and appealing to the user. Here, as they say, “it depends on the taste and color...”;
• materials. Most often, external batteries have a plastic case and this is enough. Plastic is usually durable, but it will not survive strong impacts and falls. If you regularly need to take a power bank on hikes, tourist trips, etc., then batteries in a metal case are available for this purpose. Strength increases significantly, but the weight and cost of the device also increases;
• charging an external battery. Be sure to choose a battery that can be charged from electrical network. The USB interface is also good, but a power connector for charging the device must be available. Otherwise, charging the external battery will take a very long time;
• indication. Inexpensive batteries have LED indicators that approximately indicate the state of charge. Much less often there is a liquid crystal display with detailed description and accurate indication of charge level. Such external batteries are much more expensive than the first option. But, if finances allow, then it is better to buy the second option;
• additional options. Manufacturers try to attract attention to their product and equip their power banks with additional “tricks” such as an alarm clock, flashlight, solar battery, etc.

Examples of external phone batteries

Below we will look at several examples of external batteries from various manufacturers.

The cost of this external battery will cost the buyer about 3 thousand rubles. The capacity of TP-LINK TL-PB10400 is 10400 mAh. This battery can be classified as universal.

If you are lost among the array of offers for external batteries, this top power banks can help you weed out doubts and settle on a specific model. Almost every one of them has modern people already there mobile gadget- be it a smartphone or tablet, laptop. These devices are portable and can be carried anywhere. However, the main difficulty with each such device is battery life. Unfortunately, even with all modern technologies have not yet learned how to create a battery that is tiny in physical size for a flat panel stylish smartphone— Manufacturers are still limited by the size of the device. So if you are an active person in life who does not sit at home, the problem of recharging your device is very relevant. And until recently, it was solved only by planning your route: from outlet to outlet. Travelers suffered especially - they had to buy devices that were either very bulky, or overpay for additional removable battery, or spend “cosmic” money on innovative specialized developments of solar batteries - all in order to power your gadgets without access to electricity.

With the advent of power banks and external batteries, as they say, life got better. There are a lot of interesting batteries on the market, and to make it easier to navigate, we offer our list of the best power banks. At the end of the article, we have organized them all into categories, so it will help you determine your needs and make a choice.

Imagine this situation. A used mobile phone along with an old battery has fallen into your hands. The latter seems to be working so far. But sooner or later you will still have to buy a new one. Or maybe you decided to purchase a spare battery for your new device. Which one to choose? Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) or Lithium Ion (Li-ion)?

They say they also appeared lithium polymer batteries(Li-pol). Which container is preferable? There are many questions. Let's try to understand everything in order and consider the main advantages and disadvantages of each type.

Nickel-cadmium (NiCd) batteries
NiCd battery - a veteran on the market mobile devices communications. Has a lot of advantages:

• excellent performance in a wide temperature range, including negative ones;
• long service life: over a thousand charge/discharge cycles;
• low sensitivity to improper use;
• easy recovery when capacity decreases and after long-term storage;
• low price.

Of course, there are also disadvantages:

• the need to periodically completely discharge the battery to eliminate the “memory effect”;
• high self-discharge (up to 10% during the first 24 hours);
• large dimensions.

Due to size and disposal problems (cadmium requires special disposal), NiCd batteries are gradually leaving the market cell phones.

Nickel metal hydride (NiMH) batteries
The NiMH battery has replaced the NiCd. It is distinguished by:

• greater (by about 30%) capacity than NiCd batteries with the same dimensions;
• less prone to “memory effect” than NiCd - recovery cycles need to be performed less frequently;
• less toxicity.

However, in a number of parameters, NiMH batteries are still inferior to NiCd. They have fewer charge/discharge cycles (about 500), higher self-discharge (1.5-2 times higher) and a higher price.

Lithium-ion (Li-ion) batteries
Li-ion batteries are gradually gaining positions in the device market mobile communications, which is due to:

• approximately twice the capacity of NiCd of the same size;
• low self-discharge (less than 1% per day);
• absence of any maintenance requirements, except for the need to store in a charged state.

However, Li-ion batteries from some manufacturers can only operate at positive temperatures; they are subject to aging even if not used, plus the high price. Capacity deterioration is observed after about a year of operation. After two years, the battery practically fails. Therefore, Li-ion batteries are not recommended to be stored for a long time.

Lithium polymer (Li-pol) batteries
Li-pol batteries have recently appeared on the market for cell phones and laptop computers. With approximately the same density as Li-ion batteries, Li-pol can have different geometric shapes - for example, they can be very thin to take up any available space.

How to buy batteries?

The first thing to consider is weight, dimensions and price. NiCd is the largest and heaviest, being about twice as thick and heavy as Li-ion. The NiMH battery is noticeably lighter and smaller than NiCd, but larger and heavier than Li-ion. The picture is similar in terms of price: as cheap as a NiCd battery is, Li-ion is just as expensive.

Second point. When batteries are sold, their service life is usually not advertised. If NiCd, with proper use, can last three years or more (even with daily charging), then NiMH, with intensive use, will only last for a little over a year, and Li-ion for about one and a half to two. A NiMH battery will exhaust its resource in terms of the number of charge/discharge cycles, and Li-ion will simply grow old, even if the number of cycles possible for it is not exhausted, and it will simply lie on the shelf.

Long-term operation of NiCd batteries will require increased attention to their maintenance. It is recommended to discharge them completely before the next charge, and periodically, approximately once a month, carry out recovery cycles. The same requirements, although to a lesser extent, apply to NiMH batteries (regeneration cycles here are required half as often). In this regard, Li-ion batteries are the undisputed leader: they do not require any special maintenance. They can be charged at any time of the day or night, without waiting for complete discharge.

Third. Try to buy batteries from the same manufacturer as your phone. Branded batteries, as a rule, also have branded quality. If you are offered batteries from another manufacturer, consult those who have already dealt with them. Be sure to get the seller's consent to accept the battery back if you are not satisfied with it, at least within 2 weeks. Immediately after purchase, check the operating time of your phone several times with a new battery and compare it with that specified in the operating instructions. Compare the obtained value with the operating time on the previous battery (take into account the difference in capacity). The best option assessing battery parameters - before or after purchase, test the purchased battery on a Cadex 7000 type analyzer.

However, even if all conditions are met and the initial 100% capacity of the battery, during operation, a premature decrease in its capacity may occur, caused, for example, by violations in manufacturing technology or some of your incorrect actions. Therefore, it would be a good idea to periodically monitor the battery parameters on the analyzer.

General rules for using batteries:

1. To increase service life, new NiCd and NiMH batteries are usually supplied in a discharged state, so the battery must be fully charged before use. The battery reaches its maximum capacity after 3 - 4 charge/discharge cycles. This rule also applies to Li-ion batteries, but they are supplied already in a charged state.

2. To increase the service life and capacity, NiCd and NiMH batteries must be completely discharged (in the phone or charger) before recharging. It is recommended to charge the battery after the phone is left turned on and turns off due to battery discharge.

3. If for one reason or another you are unable to completely discharge the NiCd or NiMH battery before charging, do so later. And perform full discharge/charge cycles at least twice a week.

4. It is very convenient to have a spare battery. This will allow you to constantly charge the NiCd or NiMH battery in your phone to full discharge and thereby increase its service life. In addition, you will be insured against accidental breakdowns and will be spared the need to charge the battery if it suddenly stops working in the middle of the working day.

5. Do not leave the battery in cold or warm places, such as in a car in winter and summer or near a radiator. A phone with a cold battery may temporarily not work, even if it is fully charged. Try to store the battery at a temperature from 15°C to 25°C (temperature limits for NiCd or NiMH batteries are from -20oC to +45oC and from 0oC to 45oC for Li-ion).

6. Do not charge a warm or cold battery. Wait for it to reach room temperature. Optimal temperature for charging 15 - 25oC.

7. The operating time of a charged battery depends on its real capacity, the intensity of phone conversations, the distance that takes you away from base station, on operating mode and ambient temperature.

8. Use the chargers that came with your phone or purchased from your operator cellular communications exactly for your battery type.
