Battery runs out fast

[AAHamour]

Hi, i have S21 Ultra? The issue is that the battery life is very short, after all charge, it lasts only half day.

I made all the adjustments to make last longer, but it's not getting any better.does any one have the same problem or its just my phone

By the way am a moderate user and my previous phone S10+ used to last more than 24 hours in one charge

1. Use power saving mode
2. Go settings -device care - battery- background app limit and put all unused app to deep sleep mod
And put all normal using app to sleep mode

Yes this is the solution

Thanks allot guys, I will try that for a couple of days, although i thought with a 5000 Mah battery i wouldn't need to resort to such measure, as I wanted to enjoy to top performance of my devise

Normally I would get 7-8 hours SoT under heavy load. However some 3rd party apps are the cause of the battery drain. As advised by @HUZAIN by adding those power hungry apps in sleep mode it will restrict the data process and updates on the background when not used. This will significantly increase the battery longevity

One UI 3.1 drains battery so fast. Experiencing with my S10+ since updated

Is this a new phone? If yes then it may take a while to settle down and the AI will learn your usage pattern. You can also set up automation in the

Device care > click the 3 dots on top right side and enable automation.
