Battery issues

[Denisa02]

Does anyone has battery issues on s21 ultra? I bought this phone last week and in 4h is 50% after full....i can't believe this is possible, with my last s20ultra didn't have this issues. 

Thanks

My s21 plus was like this for the first couple days.. But now its slowly getting better.. In the settings it did for the first 2 or 3 days say "learning usage pattern" so I presume as you use the phone and once its learnt this you should see improvement 🤞🏼

there are all sorts of things that can reduce a phone battery
check your screen brightness, Bluetooth and looking for a WiFi signal, also screen time and remember to close open apps..
these are just some of the things to do .... oh and dark mode will help a little.

Yes i had that when I first got my Galaxy a51 5g. The battery life wasnt bad just not as good as expected. After 5 days it was so much better 😊

samsung phones are always terrible to begin with, for a reference my s20 5G on 60hz WQHD+ will comfortably do 4 hours on a single charge if you tame it a bit you can get 5 to 6 hours sot

Great advice, another great battery saver... Turn off the device. It seems to work wonder 🔋💯

my s21 ultra battery is still doing the learning thing. i generally overnight, yesterday took off charge at 5am to leave for work. 10pm it was at 55% with moderate usage through the day.
