How to save battery on any smartphone: Android and iPhone

ByCassio Pereira

Improve battery life

Battery life depends on both hardware and user habits. Lower screen brightness, enable adaptive brightness, use power saving mode, disable unused radios such as Bluetooth, GPS and NFC, keep the operating system updated and reduce unnecessary background activity.

Best practices

  • Use Wi‑Fi when possible.
  • Avoid extreme temperatures.
  • Use certified chargers.
  • Review app permissions and background sync.

These recommendations apply to both Android phones and iPhones.
