Properly charging your phone is essential for maintaining the health of your battery, and ensuring better battery life and increased safety in the long run.
Increase the Life of Your Phone's Battery
Don't let your phone overheat
Heat is perhaps the worst enemy of lithium-ion batteries, the kind most smartphones use. You should take basic precautions like not keeping your phone on the dash board of the car where it will get a lot of direct sunlight.
You should also avoid charging your phone while playing graphically intensive games, because that will also raise the temperature of the phone and harm the battery
Don't use your phone while charging
In general, avoid using the phone while it is charging. This is called parasitic charging and this kind of usage can apparently be quite damaging.
Don't use a fake charger
One important piece of advice is to use only the company's own chargers - this is particularly important if your phone supports quick charging.
There's no need to fully charge your new phone when you buy it these days, since the battery is usually charged when you get it. And you don't have to charge the battery up to 100 percent all the time either. On the other hand, you shouldn't let the battery go down to zero either.
Don't leave the phone on the charger all night
While charging your phone overnight will probably not damage it, there is a chance that it is hurting your battery life.
