From what I studied it’s best practice to keep your Li-Ion fully charged. Keeping your battery discharged for a long time may decrease your battery lifetime. Yes, of course there are safeguards, but it still isn’t healthy for the battery. It’s not like going under a magical barrier of 3500mV causes damage to the battery, and one more mV causes no downsides at all. That’s nonsense.
Here are some overall tips on how to get the most out of your Li-Ion battery:
- Do not charge your battery when you’re running highly demanding tasks.
- Do not soft reset your phone when you’re charging.
- Do not discharge your battery when it’s not needed.
- Keep your battery dry.
- Do not expose your battery to temperatures above 50C/122F or below 0C/32F.
Follow those easy rules, and your stock battery should last at least 2 years. Thank you for taking the time to read this guide. Got questions? Feel free to ask in the comments down below.
