How to choose a battery for a smartphone

When choosing a battery for a smartphone should first pay attention to the model of this component.

How to choose a battery for a smartphone: what is desirable to consider

The main criteria for choosing a battery for a smartphone are:

1. View (external, internal removable, internal non-removable);

2. Capacity (for internal);

3. Characteristics of external batteries (capacity, case material, output current, number and types of connectors, support for fast charging technologies).

Types of batteries

The concept of "battery" in relation to smartphones is quite extensible. This term can be referred to as a built-in battery, and external, designed to recharge the device away from the outlet. In English-speaking online stores, devices of the first type are called battery, and the second - power bank.

External battery (portable, power bank, powerbank)

An external battery is a simple device designed to recharge a smartphone or any device away from the "socket". Structurally, it is a battery connected to the power controller. Being charged, it can save accumulated energy for some (relatively long), and then share it with a connected smartphone.

External batteries are not able to replace a damaged smartphone battery or just a charger. They are designed specifically for storing a certain amount of energy "in reserve" in case of a sudden discharge of your favorite device.

Internal removable battery

Internal removable batteries are installed directly into the smartphone, most often under the back panel, and are designed to power the mobile device. Removable design implies that such a battery can be removed if necessary - to replace it with another one or turn off the device completely.

Internal non-removable battery

Internal removable batteries are structurally similar to removable with the exception of a few "but". Firstly, they are located behind a non-separable case, as a result, without special knowledge and equipment, it is almost impossible to extract them. Secondly, the connection of such batteries with the motherboard has a more compact size. Finally, the lack of high-resistance connectors allows the use of fast charging technology.

Which battery to choose?

When choosing a battery, it is worth considering several parameters depending on the intended use:

1. Check whether a removable or non-removable battery is installed in the smartphone. Removable can be replaced independently, and to remove the non-removable and install a new one, you will need to carry the device to a service center;

2. What do you need a battery for? If the smartphone battery began to sit down quickly and it has been more than a year since the device was purchased, it becomes very hot or almost instantly discharged in the cold, then you need to replace the internal battery. If you just want to extend the autonomy, you need an external one;

3. In order to extend the autonomy of a smartphone with a removable internal battery, you can purchase several internal batteries and change them as you discharge. But this is not as practical as using a power bank.

Battery selection options for a smartphone

The options for selecting internal and external batteries are different.

Internal battery

When choosing an internal battery, you should pay attention to the following characteristics:

1. Model;

2. Compatibility;

3. Capacity;

4. Manufacturer.

The model is especially important for internal non-removable batteries. It directly determines the possibility of installing the battery in an existing smartphone - and by design features, and by electrical parameters. You can find out the specific model both from the sticker on the existing battery and from the specifications of the device.

For internal removable batteries, the model is important, but not prevailing.

Compatibility determines, as the name implies, battery compatibility with an existing smartphone. It can be both constructive and electrical. Compatibility of the first type implies the ability to install the battery in the smartphone - it must have the same dimensions and the same arrangement of contacts as the original one. Electrical means that the current and voltage will be the same as used in the device.

Compatibility is usually indicated on the packaging and in the battery description.

Capacity determines the battery life of the smartphone from the battery used. The higher it is, the longer it will “live” the device without recharging. However, in most cases the capacity of the new battery corresponds to the same parameter of the old one.

Portable batteries

When choosing a portable battery, you should pay attention to the following characteristics:

1. Capacity;

2. Charging current;

3. Housing material;

4. The number and types of connectors;

5. Support fast charging technology.

Capacity determines the battery life of the battery. More precisely, it determines how many times the power bank is able to charge the smartphone connected to it. Most modern mobile devices are equipped with a battery of 2000-3000 mAh, so the external charger should be taken at least 5000 mAh, since its self-discharge, drops during current transfer and other factors that reduce the actual capacity are observed.

Charging current determines the charging speed of the connected smartphone. For older devices, the optimal value of this parameter is 500 mA. For new smartphones, it is pointless to buy external batteries rated for less than 1 A. They will be discharged faster than charging.

Body material determines the practicality of the power bank. Plastic is cheap, but scratches easily and cracks when dropped. Metal is a bit more expensive, but it is more practical.

Number of connectors determines the number of devices that can be charged from one "power bank" at the same time. If the external battery is planned to be used only with a smartphone, one connector will suffice. If with a laptop, tablet, headphones, smart watches or similar device, you will need at least two connectors.

Connector type determines cable compatibility. The most common standard is USB Type-A - or “regular” USB. Modern USB Type-C is still quite rare. Even smartphones that are equipped with them are usually equipped with a USB Type-A cable on one side and a Type-C cable on the other.

Support for fast charging technology will allow energy to be restored in the battery of a connected smartphone (which also supports it) much faster than usual.However, it leads to intensive wear of the power bank batteries.

How to choose an external battery for a smartphone

When choosing an external battery is to solve a few questions:

1. Capacity. The minimum required is 5000 mAh. Taking into account external factors, it will allow you to charge your smartphone from 0 to 100% once. Better, of course, 10,000 mAh or even higher;

2. The number of connectors. On external batteries rated for less than 10,000 mAh, it makes no sense to install more than one port;

3. Charging current For new smartphones, it must be at least 1 A;

4. Material. It is worth choosing based on your own preferences.

5. Support for fast charging is not really needed.
