How do I make my phone battery last longer?

Keep the charge between 20% and 80%, avoid heat above 35°C, and use slower charging overnight. Lithium batteries age from time spent at high voltage and high temperature far more than from number of charges.

Follow-up questions

Is it bad to charge your phone overnight?

Modern phones stop at 100% and most now offer optimised charging that holds at 80% until morning. Enabling that feature removes almost all of the risk.

What is battery health percentage?

It estimates current maximum capacity versus new. Below about 80% you'll notice shorter days; that's the usual threshold for replacement.

Does fast charging damage the battery?

It generates more heat, which accelerates ageing slightly. Occasional fast charging is fine; daily fast charging in a hot car is not.

Which settings drain battery fastest?

Screen brightness, always-on display, 5G in weak-signal areas, and background location for apps that don't need it.
