According to hvg.hu, your smartphone lasts for a short time not just because there is not a big enough battery in it. Behind the phenomenon is partly that almost everyone incorrectly charges it.
Don’t charge it fully
The website Battery University, which is owned by a battery company, warns that lithium-ion batteries do not require a full charge – neither at the first charge before the first power-up, nor after that. Indeed you do the right thing, if you always just charge somewhat, but not until 100%
Don’t leave charging at night (either)
The previous advise allows you should not let the battery on the charger for a longer period of time: however, if it is kept plugged into, there will be always charged, but the more times the battery is fully charged, the less it holds on in the long run.
The graphic shows that the capacity (green line) reduces almost to zero even after 200 charges, while the capacity of a battery, which is not fully-charged, reduces only by about 20% even after 400 charges. The point is: do not leave it unattended charging for too long: 80-90% charge will be plenty enough, hvg.hu said.
Instead of a few large bursts, it is much better if you charge it only partially – but you should do it whenever you can. The best is, if you charge it a little at 80-90% – of course, it is just the ideal case which is difficult to implement in everyday use. But you can strive for it.
Don’t charge it in very cold or hot weather
The Battery University advises the ideal charging temperature is between 10°C and 30°C. Although probably few people charge their phones under 10°C, but it can occur for example at the garage in winter. In the summer, the charging phone can remain in a place higher than 30°C (for example, in a car). It’s also not good for the battery.
Forget the charger when it makes the phone hot
It is natural that the device is a little warmer while charging. But if you feel it very warm, do not use the charger anymore.
