I got AUB9 on a brandnew S21Ultra. The phone was factory reset before even installing anything, cache cleared. Cam drains battery ENORMOUSLY, without showing anomalous use. This phone is an utter catastrophy and goes back immediately for a refund. This was my last samsung phone EVER. Not going back. Exynos needs to finally die. The overall software is amazing, but this is all useless without a battery. I'll switch to the OnePlus 9 pro. Please, STOP telling people that avoiding smart switch will help, It's a lottery at best and there are a billion other issues that will never be fixed. Refund your phones if you experience this, don't listen to that pathetic: "iT nEeDs tO lEaRn uSAgE pAtTeRn" No other brand needs this, and no other brand has systemic drain issues. No, samsung, this phone doesn't need to learn anything, a 1300 dollar phone just needs to work out of the box, like other flagships. You don't deserve this, folks, ditch samsung and make them respect the customer, this is UTTERLY SHAMEFUL business practice.
Not sure it does. My SO's s10+ runs One UI3 and there it doesn't drain, it doesn't drain in my friend's s20. I just have a broken device. Cam sucks too, overheats ...drains multiple % in minutes.
With all due respect, if you read my post you'd know that this isn't the issue. Phone overheats with cam too. Cam is an even bigger problem. I got a faulty device.
Charge your phone to 100% and then run it in Safe Mode for 2 or 3 hours and then report back on your battery usage, with screenshots.
No need to get patronizing and apologetic. All those drain issues and exynos issues are widespread and confirmed. Last scamsung doorstop I ever owned. ANY manufacturer can do better than this, because they at least sell you snapdragons, instead of this low tier exynos trash.
I have issues with my battery too. I already lost 25% with 40 min SOT which is not good, if I'm right? Already tried everything as put apps in deep sleep and etc... The only thing that I didn't try is factory reset but I'm not sure that this will help me.
