These Android battery saving tips come down to four habits: find the app or setting that drains most, dim and slow the screen, stop the phone hunting for signal, and let power saving mode handle the rest. They work on Samsung, Tecno, Infinix, Redmi and most other Android phones, and they matter most on days when KPLC is off and you can’t top up.
Find what is draining your battery
- Samsung: Settings > Battery (or Battery and device care) > tap the usage graph.
- Tecno, Infinix, Redmi and others: Settings > Battery > Battery usage (or Power consumption).
Look for one app taking far more than the rest. If an app you barely open sits near the top, restrict it or uninstall it.
Screen, network and location settings
The screen and the radio use most of your power.
- Brightness: turn on Adaptive brightness and lower the slider a step.
- Screen timeout: set it to 30 seconds.
- Refresh rate: if your phone has 90 Hz or 120 Hz, choose Standard (60 Hz) on long days. On Samsung: Settings > Display > Motion smoothness.
- Dark mode: saves real battery on AMOLED screens (most mid-range and flagship Samsungs) but very little on LCD screens, which many budget phones use.
- Weak signal: a phone in a poor-coverage area keeps boosting its radio to find a tower. In a dead zone, switch on Airplane mode or turn off mobile data until you’re back in coverage. In patchy rural areas, locking to 4G instead of 5G can help too.
- Location: set apps to “Only while using the app” and switch off Wi-Fi and Bluetooth scanning (Settings > Location > Location services).
Power saving modes
- Samsung: Settings > Battery > Power saving. You can set it to switch on automatically at a chosen percentage.
- Tecno and Infinix: Settings > Battery > Power Saving or Ultra Power Saving, which leaves only calls, SMS and a few apps you choose.
- Redmi/Xiaomi: Settings > Battery > Battery saver or Ultra battery saver.
On a long outage day, switch power saving on early, at 50%, not at 10%.
Apps that drain in the background
- Samsung: Settings > Battery > Background usage limits > put rarely used apps in Sleeping or Deep sleeping apps. Keep messaging apps out of Deep sleeping, or you’ll miss notifications.
- Other brands: open the app’s info page > Battery > choose Restricted (or “Restrict background activity”).
- Turn on Adaptive battery where your phone offers it, so Android learns which apps you rarely use.
- Switch off auto-play in social apps and cut needless notifications.
- Skip “battery saver” apps from the Play Store; the built-in tools do the job and those apps often drain more than they save.

Quick answers
Check Battery usage for the worst app, lower brightness and screen timeout, use Airplane mode in no-signal areas and switch on power saving early.
Use Power saving, put unused apps in Sleeping apps, set Motion smoothness to Standard and use dark mode on its AMOLED screen.
Yes on AMOLED screens, where black pixels are switched off. On LCD screens the saving is small.
