Battery that lasts
- Lower screen brightness and use dark mode.
- Turn off GPS, Bluetooth and WiFi when you do not use them.
- Android: Settings → Battery shows which app eats power. iPhone: Settings → Battery.
- Charge between 20 % and 80 % when you can; avoid leaving the phone hot in the sun or in the car.
- Use a good charger. Cheap unbranded chargers damage batteries and can be dangerous.
Free up storage
- WhatsApp: Settings → Storage and data → Manage storage, then delete big videos and forwarded files.
- Turn off "auto-download" of media in WhatsApp groups.
- Back up photos to Google Photos or iCloud, then "Free up space".
- Clear the cache of big apps (Facebook, TikTok) in Android Settings → Apps.
Save mobile data in Cameroon
- Turn on "Data saver" (Android) or "Low Data Mode" (iPhone).
- Set app updates to WiFi only (Play Store / App Store settings).
- Watch videos in lower quality on YouTube and TikTok when on mobile data.
- Compare bundles in the official MTN and Orange apps (MyMTN, Orange Max It) before buying: night and weekly bundles are often cheaper per GB.
- Check your balance and bundle with the official USSD code shown in your operator app, never with codes sent by strangers.
Stay safe
Lock your phone with a PIN or fingerprint, and lock your mobile money with a separate PIN. Never share codes you receive by SMS: no real agent will ever ask for them.
