Problem with battery

[Members_7JYMJtS]

I've noticed since I last updated the S23 System update. I've been having a lot of problems. I charge my phone as normal when it's about 80%. I've noticed that my battery is drained quite quick. Whenever I start playing a game, I only get to play one round before the sound starts to break up. Then it switches itself off due to it saying there's no power. I know if outside the cold can drain it quicker but it shouldn't happen when I'm indoors.

What update was it? 

Try with clearing phone partition cache

Then use diagnostics via Samsung members app

Hi, and warm welcome 👋

You should charge your battery when it drops to 20% or a bit above and never let to discharge fully to preserve batterys lifespan.

In settings > battery see what apps draining most of your battery try to reinstall these app/s.

Try wipe cache partition:
Turn off your phone, plug into PC, tv etc via USB Then press and hold power and volume up button until samsung logo appears Then quickly release power button and keep holding volume up button until reboot menu appears then navigate with volume down button till wipe cache partition press power button to confirm then restart your phone.

Try safe mode and see if 3rd party apps, themes etc might be causing this:

You can also try Batterystas reset, to do so :
Open your phones dialer type *#9900# (autobleckes needs to be turned off and default Samsung's phone app needs to be used) than scroll until you see batterystats reset press on it.

Also you can put unused apps to sleep to save more battery.

If this was my phone @Members_7JYMJtS I'd first run the diagnostic tool found in your Samsung Members App to see if that highlights anything, but if it does not then let a Samsung Service Centre or Samsung Experience Store have hands on. 

If i can be of any further help please don't hesitate to ask  😎
