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!
