We got exactly the same battery issue I see.. I'm barely getting 4 hours in a day, as well.
I think there are some kind of wake locks from the system. When I activate power saving mode, standby drain is a lot better tho..
So I am a long time Samsung user. I had the S20 plus and wanted to try the smaller S21. Only because of the trade in for the plus with Samsung. I have the S21 256gb unlocked snapdragon version. I just got the phone yesterday. Here is a copy of my battery life after getting my apps loaded. The battery life is almost 7 hours screen time which is all on WiFi. Mostly logging into my apps and cleaning up contacts and playing with the phone. After a few days I'm sure the battery life will get better.
Yess!! Let's hope it solves my drain on the S21 base model as well.
I installed this update today on my S21, but Samsung seems to have removed it from the ota servers. Weird I hope this doesn't hide a bug yet. Because available this morning and withdrawn this evening.
I saw it with phone info, because after having updated the last firmware in OTA had returned to AUB8. But honestly yes a visible change. I charged 100% last night, this morning I am at 87% after 12:23 hours of use. And 1 hour of stupidity.
Have no issues on two(2) phones directly from Samsung. Both have received a 690 mb size update within last week and both were wiped cache after setup and updates.
Disabled about 25 apps and services via ADB AppControl Extended version.
Both are charged up until about 85% battery and then disconnected and used heavily for work about 6 to 7 hours daily. In the morning, charge level is around 45% and charged until 85%.
Totally agree with you. I've had this phone for over 3 months and no trick or update software from Samsung has improved anything. Never over 4 SOT. Just sad and bad...After over 2 months with this phone I'm replacing it for a pixel 5. Just released dxomark review confirms my impressions about the pictures and video capabilities - i wanted an upgrade from P30 pro but it's not the case. I tried a lot improving my battery but still it's never over 4h. If I enable volte it drops to 3h.
Battery life is bad with 4G turned on, so samsung should fix that, either they have some problem with baseband or they have wakelocks triggerd by 4G. With 3g battery life is pretty decent with bluetooth and gps on, 120hz and sync turned for all apps. What's the point of having smartphone and flagship if you have to turn off every functionality?Meh, bitching here does nothing. Y'all need to do what I did; play with it and work it out.
Find work arounds for the bad coding.
Had I not taken the -time- and trouble to do so my 10+ still be a battery hog.
Just gave you 3 or 4 good solutions. Devise your own... as each variant and user have their own unique issues and requirements.
Stock Androids are fun to play with... and almost crash proof.
Lol, a lot easier than doing regedits
Amazed that all you allegedly tech-savvy guys are worrying about battery life with a phone that's less than a month old. The AI has to learn your usage pattern before battery management can kick in that takes about two weeks and the battery will not reach its full capacity for about a month that's why AccuBattery reports it wrong. Then some of you are doing resets or worse so the AI has to start learning again. Sad
