"They're also charged to full capacity or depleted to empty a lot of the time."
Does it affect battery life if I keep my phone charged even if it's at 100% ? (My phone is charging during the night, so it will be at 100% for a long time and keep charging).
If it reaches 0%, how does that impact battery life compared to reaching 20% and charging up ?
I never looked up these things but it might influence how I charge all my devices.
