Samsung S21 8/256, super bad battery life

[Stacey S21]

Enabled all possible battery life saving methods, still my Samsung S21 still drain my battery: FAST.

I got my new phone (model SM-G991B) on Monday, April 12 2021 > and have not yet used my full workflow on it. Screentime is aprox 3 hours. Still I must charge my battery 2 times a day. This is a big No Go. 

With this drainage, I can't rely on this phone for a full workday outside without any charging outlets available. 

I hope Samsung will fix this with a software upgrade.

Can you post your battery stats? Go into battery and device care,tap the graph and you should see what's eating your battery.
I'm getting just over 2 days on one charge so something isn't right.

If you have only had it 2 days then its still learning your usage pattern so battery may be a little all over the place for 5 days to a week. If it continues past a week then something isnt right at all.

Thanks for the information. WhatsApp is eating the battery (more than when I'm not active). I could place it on Deep Sleep mode, but then I won't get any push notifications. 

If I look at my battery usage it states that "A full charge will last about: 14 h 51 m > so not 48 hrs (just like yours).  

WhatsApp: active 1hr 40 m (background 3h) > 24.1%
Teams: active 55 m (backround 32 m) > 12.5%

I will check this. If it's not adjusting after 1 week, I will let you guys know.

Ok fingers crossed the battery settles down on your phone. It must be mega annoyibg to have bad battery life on your phone. Im lucky my phone's battery life is super good. Keeping my fingers crossed that the battery on your phone inproves once it has learned your usage pattern 🤞🤞

Please don't hijack other people's threads, it's bad netiquettte.

[Stacey S21]

Huh? I don't understand your message. Please do explain. 
I hope I will get 48 hours of battery life (like yours), but for now, I don't get this. I will check if the battery life adjusts within 5 days, and if not, somethings definitely wrong with the battery

oh hi the thought police. seeing as the OP liked the message and it was a confirmation, how about you don't tell people what they can and can't do, that's bad etiquette.
if you can help, awesome, not here for speech policing pal 👍
