Hello, I recently updated my S8 from Nougat to Oreo and I noticed a HUGE difference in battery life. I usually have a SoT of 4-5+ with heavy usage. But since the update, my battery would only last around 2 SoT more or less. I had already done a factory reset and turned off Bixby but my battery is still draining.

I've also heard some people said that the new update requires the phone to "settle" and store the cache so it can "get used to" my usage, with a minimum of 1 week (only had this update for 2 days). I'm not sure if that's true but I don't seem to have many options right now which is why I'm now open to any other suggestions and if all suggestions are done and draining still persist, I might have to roll back to Nougat. Thank you.

Try disabling bixby apps. It helped to a lot of users (not me)

you have to master reset, after a major update it's always good to factory reset

I forgot when in the apps section in settings you got to hit the 3 dots on the top right and select show system apps then scroll down to the phone app the select then battery then disable allow background activity.

S8 Oreo Battery Drain
Good Afternoon,

The 3 phone services to disable the background activity has worked a bit but my battery is still draining pretty good... is there any other services I can check to see if the background activity is being used somewhere else?
