My is using a of the brightness is minimum and all connections are of.

My phone is redmi note 6 pro, I bought it 2 years back.
Even in the power save mode the battery drains and there are no major apps using my battery , only the screen is using a hefty amount of my battery.
Even in night it was 80 % charged and in the morning it remains about 40 % . I have tried every hack fr this. Kindly help.

Hi there. Put your phone into safe mode and see if the battery drain continues. Safe mode will prevent 3rd party apps from working so you can rule out a 3rd party app as the cause of the drain.

The process for turning on Safe mode is as follows:

Press and hold the Power button.

Tap and hold Power off.

When the Reboot to safe modeprompt appears, tap again or tap OK.

Your device will then restart and it will say “Safe mode” in the bottom-left corner.

Welcome to Android Central! Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:


1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which may show Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
