Contrary to alot of what i read, I've had nothing but good things from the latest update on my unlocked UK version Note 10+ 5G.
After postponing it for a few weeks while i decided whether to go for it or wait, based upon the recent feedback. I gave it a go, and had fantastic battery life in comparison.
My phone is already very optimised, 99% of my apps are deep sleeping, all but the most essential apps i allow to run in the background, and use data. And i use a firewall to completely block Internet access to all apps except those who need it.
I've gone from averaging maybe 5-6 hours SoT to 8-9, which is a massive increase!
Yeah likewise my Note10+ is running like a dream - was on the Beta - been on the official update since it came out and no problems at all Not a heavy user though spend a fair bit of time on news sites and a couple of forums - battery will pretty much last best part of 2 days 😀
I noticed it says Learning Usage Patterns on your phone. Did you get it within the last week? Sometimes when you first get a phone within the first few days/first week, sometimes phone batteries run down faster. Usually it settles down once it learns usage patterns
