I have been using my note 9 since 2018 and after each software update the battery sometimes became excellent or sometimes just not so good. Although my note 9 is old but I have been very careful with it.
After September 2020 update, the battery has started to drain too fast. Whether I use the phone or its on standby, the battery keeps draining at the same rate. It drains 30-40% overnight (which is very unusual). I have even tried to uninstall many apps but still the issue is same. Just to be sure, before sleeping I cleared all the background apps so that nothing runs in background to suck battery. The phone battery is always on "optimized" mode with "adaptive power saving" always turned on.
Before I could easily spend an entire day with single charge, but now I have been charging twice a day. Does anybody know any solution? or is there any way that I can revert to the older software version?
Following is the current software version of my phone, and the overnight background battery usage activity by different apps (no app is taking a serious amount of battery):
You are right
I can agree with that. I recently updated the windows on my very old Dell. Before it was lightning fast and now it boots up in like 3 to 5 minutes 😑
This is not fair, I hope this problem is by mistake and by next update samsung fixes it
Or buying OnePlus phones is the only option left
I too have noticed increased battery drain since the last update. Tried clearing cache and that did not work. I am using over 1% an hour overnight which is double what it would normally use. Battery throughout the day also seems to going twice as fast.
You are still lucky with that. For me its going like 1% per 10 minutes. Whether I use the phone or it is on standby, the battery drainage rate is same.
I put the phone on 100% charge at night at 10pm, cleared all the background apps. In the morning at 6am I wake up with 65-70% battery 😕
I don't know what to do. I have tried to optimize all the settings but nothing helps.
