Want to know the fastest way to kill a battery? Keep it plugged in (fully charged) all the time
This is why so many batteries burn out quickly. People leave their device plugged in, day in, day out, without realising that they’re just frying their battery
When a battery is fully charged it deteriorates quicker, so avoid leaving your device plugged in all the time.
If you’re not planning to use the device immediately, leave it at 30-40% charge until you need to use it and then charge it up
The above is not and advice, its a matter of obseravtion and out own experience
