Welcome to Android Central! Which phone?

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.

Late to this post, but I have a Samsung S21 and after the update my battery drains fast with very little use now. Even if it's just sitting there. Full charge in morning and by lunch it's down to ~50%. It's becoming annoying.
