Haven't had good battery life since the AUB6 update I think anyway. Can't remember the exact build but was happy with battery life. Since the May update standby drain is really high. Screen on drains every few min. Never used to be like this. Used to be 1% every 10min the display is on which was reasonably good. Samsung need to stop focusing on camera updates and fix the bad battery life. Disappointing for a 5000mah battery. All apps in deep sleep. Auto sync off. Location off when not in use. Shouldn't have to turn everything off in order to get good battery. I've tried using 60hz but it's too laggy and jerky so I'm sticking to adaptive.

I'm waiting for a Samsung moderator to reply with a list of power saving tips 😂 THAT DONT WORK, It's 100% the software that's got issues. I wish Samsung would give us the option to roll back to previous updates so I could enjoy my phone again.

Are you cleaning cache memory after each update? It is affecting the battery life and helps usually. I am on S21 but I turned off all battery savings and let many apps to run in the background, only few in deep sleep. I don't believe turning everything off helps that much with the battery it is just making the smartphone useless to be fair

Yes Ive done factory resets. Cache wipe. Every app deep sleeping auto sync off. I've reset sleeping apps so I'll let it auto sleep apps. I'm going to turn everything on see if it's any difference.

That's the kind of battery I was getting when I first got the phone. I also wiped the phones cache partition, and run galaxy labs booster after a software update.

Chrome still continues to be the biggest battery waste for me, but I've found idle screen off battery drain to be a lot lower since last update (at least according to AccuBattery). I'm guessing the battery may be doing some relearning or quite a few apps may be updating/installing in the background lately and battery life should return to normal levels pre May update soon enough.
