Yes!!!! Yes and yes!!! I am on the 3rd beta on my S10+ and I barely get 12 hours battery time any more. 4 hours SoT if I am lucky. Accurately says I have 90% left so I should be getting longer. It is so annoying. I have complained through beta feedback. But yes. Battery life is terrible.
Today will be my second day on Android 11/One UI 3. I have yet to experience battery drain by I'm not thrilled with the update. I liked gesture navagation better on Android 10. It's janky in general, going to recents is janky using gesture navigation. Maybe I need to factory reset? Lock screen clock switches to default font upon notification. IDK.
As soon as I receive the stable build I am resetting my phone. To get rid of bugs and quirks from the update. I do hope my battery life will improve. I had to reset my husband's pixel 4xl as it had acquired some update bug that stopped his microphone from working on video calls. Sometimes after a major update a full reset is the best thing.
Not at all... on my unlocked N20U on Sprint/T-mobile I'm averaging around 30 hrs of battery life per charge. Coming from a S9+ I would have to charge before I left work after unplugging at 5am I'm thrilled with the battery life.
