Bright Side has brought some other tips about the right way to charge your phone.
#10 You always leave your charger in the socket.

As we all aware, charger is constantly drawing power when in the socket, even if the phone is not connected. This can be affects your electricity bills.

Always unplug the charger from the socket if you are not using it.
#9 You charge the battery to 100%

Don’t charge the battery of your phone to 100% every time as it will shorten its lifespan. Every battery has a precise number of charge cycles and if you always charge it to 100%, these cycles can be end sooner.
The general rule is to recharge the battery fully once a month and you need to keep it between 20% and 80% at all other times.
#8 You let the battery fully die before charging it again.

You have to remember that it’s not good to let the battery go to 0% either as the newest lithium-based batteries work in charge cycles. You are destroying your device’s longevity step by step if you let the battery die.
#7 You leave your phone to charge overnight.

You can unplug the phone and the charger from the socket if someone is calling you and after that put it back on charge once you have ended the call.
#5 You charge your phone even when the battery is above 20%.

By constantly charging your phone, it can make the battery last less than it should.
The best thing you have to do is to charge it only when it’s truly needed: this means when it is under 20%, but above at least 5%.
#4 You leave the phone case on while charging.

Heat is one of the main enemies of batteries. You are trapping the heat that is being produced by charging your phone with its case on. Because of this, the battery and other internal components of the phone will heat up.
When you are charging your phone, remove its case to let the battery “breathe.”
#3 You keep using generic and cheap chargers

Every phone has a compatible charger. You should not replace it with another one of another brand or one that was intended for another model. The power of the energy transmitted to the battery could be too much or too little if you don’t use the right charger. This could lead to overheating or to a really slow charge.
The best thing is to use the charger that you received with it when you bought it. You can reorder it, If you broke it or lost it but make sure it’s the same model.
#2 You use unknown battery apps that put the battery under strain.

You can track your battery’s performance with free apps. But you should be careful about which ones you use. The battery will put under strain and download advertising on your phone if you use pps developed by unknown sources and not rated by smartphone manufacturers.
You need to verify the source to see if it is reliable before using an app.
