Many of us remember those times when the phone was used exclusively for calls and only occasionally sms. Currently, this is almost a full-fledged diary in a pair with an alarm clock and a multimedia player. It's no wonder that the battery sits much faster and usually it takes a full charge every other day. Even more difficult for busy people who practically do not turn off the smartphone and are constantly in touch with their partners. As a result, we have a huge demand for an external battery for the phone.
What is the additional battery for the phone?
As soon as technology has not developed, and even today all types of such batteries are conventionally divided into three groups. Externally, they are quite familiar to our eyes and look like a small rectangular box device. What kind of three groups of batteries you will see on the shelves of stores:
- the most common option is lithium-ion (an undoubted plus of such devices is an ideal balance of quality with safety and energy intensity, but they also "age" faster than others);
- nickel-cadmium models were once on sale, but they were recognized as unsafe and now it is more likely just an item on our list than a device actually used;
- the most modern and perfect lithium-polymer, which are safe in an ecological sense and at the same time quite energy-intensive.
There are several myths or not quite true facts regarding batteries and their operation. In particular, recharging. There is an opinion that it is only to fully charge the phone's battery until it stops, as premature detachment is fraught with damage to the device. In fact, this statement is relevant only for older models, new lithium and polymer just do not need to be discharged to the full cycle.
Another not absolutely true fact - the need to charge the device for the first time almost 16 hours. In practice, it is right to charge the phone's battery just before the signal from the device itself, since a long time of power supply from the network can be disastrous.
Choosing a battery for your phone
Is battery capacity important, and what else can be useful for the consumer? So, what parameters are worth paying attention to when choosing:
- The question is, what is the battery capacity of the phone better, seemingly pointless at first glance, and the answer to it is obvious. However, not always the model with the greatest capacity really will be suitable for your device. Here you have to literally calculate the required capacity. The nominal voltage at the battery outlet may be different, depending on the model. As a result, two identical capacities at different voltages give completely different amounts of energy that will be stored by the devices. So this is in some way a search for a compromise between the price and the really necessary energy reserve. Consider the fact that more capacity will cost you more.
- Again, we return to the strength of the current. If you are looking for a universal device, it is worth giving preference to models with a power within 1-3 A. If you plan to use a portable battery exclusively for the phone, enough and 1 A.
- In order to purchase a very well versatile device, many are chasing models with a mass of different ports for everything that is in the house. In fact, it's rare to charge such a quantity and it's quite enough for two or three ports.
- It is worthwhile to think about additional bonuses in some models of spare battery for the phone. For example, a special body, protecting from getting dust and dirt with moisture.
The service life will be much longer, for permanent use is not the last factor. There are models with solar batteries, a tribute to modernity and at times a convenient device.
Also, when choosing a battery-charging for the phone, some users also evaluate the comfort in operation. This concerns the choice of the firm: practice shows that it is better to buy everything from one manufacturer. Also look for models where the power button does not protrude beyond the enclosure. And of course you can buy a portable battery for your phone and you need it only in trusted stores, because it can not be trivial and you'll have to return it.
