  • My battery drains about 10%-16% every hour since the new update. I do not play any app games, I have deleted most of my apps in general, I have put them all in deep sleep, I have cleared the cache, turned off adjustable brightness, ran through every little thing I can to make the battery stop draining so fast. Even writing this post, it has went down 3%. Nothing is running in the background. I have no clue what is going on. I have had a Samsung phone for 10 years now and have never had such a crazy drainage. I do not want to keep putting it in airplane mode. Someone please help me figure out why my phone is going haywire. 😩

Sorry if you know this already but in battery settings you can see which apps and phone processes are using the most battery power.. that could be a useful place to start.? Good luck.. let me know if you can't find it..
