We all use our phones a lot and battery life goes a long way. Here are three things I’ve learned.
(1) Heat is the biggest killer – especially heat combined with a full charge. Leaving your phone in a hot car or using intensive apps while charging accelerates permanent capacity loss faster than almost anything else.
This also means avoiding fast charging or wireless charging where possible.
(2) Use optimized charging. The charge from 20-80% advice is technically correct but often impractical. All you need to do is to enable optimized charging (max at 80% or 85%) when you charge overnight.
(3) Deep discharges stress batteries. While occasional full discharges aren’t catastrophic, they’re best avoided.
The practical takeaway: Avoid heat, use optimized charging, and aim to charge when you’re around 20%.
