What can I do to keep my phone’s battery healthy for longer?

Keep your phone's battery between 20% and 80% most of the time and protect it from temperature extremes. Lithium-ion batteries degrade fastest at very high and very low charge levels, and heat accelerates permanent capacity loss.

Turn on your phone's built-in charging optimization feature to reduce time spent at full charge. Both iOS and Android offer software that learns your routine and delays topping off to 100% until just before you typically unplug.

Charge your phone with the original charger or a certified third-party alternative from a reputable brand. Low-quality chargers can deliver unstable voltage and current, which stresses the battery and may damage charging circuitry over time.
