How to choose a battery for mobile phone

When choosing a battery for a mobile phone is first turn to determine its compatibility with the device.

How to choose a battery for a mobile phone: what note

The main criteria for choosing a battery for a mobile phone are:

  1. Compatible with your phone;

  2. Capacity.

  3. It is also worth considering that the battery may be internal and external. Batteries of the latter type, the so-called power banks, do not installed in the phone and designed for use as a portable charge.

  4. The battery manufacturer is also important.

Main selection criteria

The most important selection options are type, compatibility and capacity.

Battery type

By the type of batteries, they differ on internal and external (portable).

Internal batteries

internal batteries

Internal battery is a vital element phone. It is from him that everyone else eats electricity microcircuits. In fact, no mobile phone can work without an internal battery installed.

Internal batteries are always included mobile phone. They are characterized by a long operational period, so you have to change them either damage (e.g. due to drowning or swelling), or after significant wear.

“Symptoms” that signal the need for replacement internal battery are:

  1. His swelling or any other spontaneous deformation;

  2. Fast phone discharge when unexpectedly fast or, conversely, slow charge;

  3. The appearance of heat during normal use.

Of course, a long operational period is achieved. only with proper handling of the phone – it does not stay around heating elements, in direct sunlight, not used in extremely low temperature or very high humidity.

Internal batteries usually do not have cross-compatibility. Then there they are intended to be used with one specific by phone. Moreover, such “specialization” is achieved as structurally – the battery has dimensions, shape and location contacts, allowing you to set it only in the lodgement of a specific Models and at the electrical level – current strength and voltage Battery power intended for use only in compatible electronics.

As a result, try to install the battery from one the phone in the lodgement is not worth another – even if it is possible structurally, not the fact that he doesn’t “kill” the delicate electronics inside the device.

Portable batteries

Portable batteries

Portable batteries (external, power banks) are not an alternative for domestic. The phone will not be able to work only from like a battery. Portable batteries are designed for “emergency” recharging of the device in conditions of inaccessibility regular household network – on long trips, tourist hiking or with a banal power outage.

The principle of operation of an external battery is quite simple. First it charges itself, then saves energy for some time (usually quite long, of the order of several weeks), and when you connect the phone recharges it.

Compatibility

As mentioned above, various manufacturers of mobile phones make devices with different forms of lodgment for accumulators and current-voltage characteristics of batteries. therefore It is very important to determine compatibility.

Usually it is indicated directly on the battery packaging. Its technical specifications list devices to which he will do.

An alternative is to search for a battery by specific model of the battery itself. It can be found on the sticker on this the battery itself.

Battery capacity

Battery life depends on battery capacity devices. Therefore, the higher it is, the better. But it’s worth remembering that very high capacity batteries usually differ quite large sizes and therefore may simply not fit under the back device cover.

It is desirable that the capacity of the new battery matches capacity of the replaced or slightly exceeded it. Then maximum compatibility will be provided.

How to choose an external battery for your phone

How to choose an external battery for your phone

An external battery, it’s also a portable charger, designed to restore energy in the internal smartphone battery. Therefore, the main criterion for selection is capacity of this device. Additionally, you can pay attention also on output current and housing material.

External battery capacity

The higher the capacity of the external battery, the more times it will be able to recharge the phone. However, the feature of mobile phones lies in the fact that they are initially equipped with pretty “small” internal batteries. On average, their capacity It is about 1000-1500 mAh.

Therefore, they really don’t have a really large external battery needed. Even a budget model at 5000 mAh will be enough for 2-3 recharging. To purchase a more “capacious” battery is meaning only if long trips are planned.

It is worth remembering that the battery capacity indicated on its packaging, a little different from the real one. This is due to a number of factors including self-discharge, transmission loss, and other purely physical phenomena. Therefore, an external battery designed for 5000 mAh, enough for 2 phone recharges, built-in capacity whose battery is 1500 mAh.

For urban use and short trips will be enough battery rated for 5000 mAh. For long When traveling, it is advisable to purchase models of 10,000 mAh or more.

Charging current

The charging current determines the charging speed of the phone. Than it is higher – the faster the internal battery of the device will restore its stock.

But there are also a few buts. Old mobile phones do not rated for high charging current – when powered more than 1 A they can just burn out. In addition, such a high amperage can damage the internal battery.

Therefore, for use with mobile phones it is advisable to purchase external batteries designed for 1 A or even less. Of course, in this case, a full charge will take quite a lot of time (up to several hours), but the risk Damage will be minimal.

New mobile phones (such as those released by Nokia at 2016-2017) can work with high charging currents. For they can be purchased powerbank, designed for 2.1 A.

Body material

Some practical and power bank operational properties. Usually such devices made in metal or plastic design.

  1. Plastic is a cheap and quite practical material. Not less, it is not scratch resistant and may be damaged by fall. Therefore, it is advisable to use plastic power banks very neat.

  2. Metal is more expensive, but also more stable. It is not scratched and not cracking. The disadvantage of metal is its thermal properties. It freezes quickly and leads to intense self-discharge. built-in batteries in the cold. Therefore metal external batteries are not very suitable for use in low temperatures.

Top Phone Battery Manufacturers

Among the manufacturers of the highest quality domestic The following companies can be distinguished batteries for phones:

  1. Craftmann;

  2. TF1 (TelForceOne);

  3. Partner

Of course, the best internal batteries are original, then there are those released by the same company that produced the phone.

Among the manufacturers of external batteries can be identified:

  1. Inter-Step;

  2. Xiaomi;

  3. Hiper.

  4. For modern phones, Canyon products are also suitable.
