Well, I have done the same as you have (cleared cache partitions, disabled & set battery saving options on all) but my battery still is being drained about 10 hours quicker than it used to be. Not happy
@userMRQF7CvrPs Here are a couple other things you can check to help with the battery life.
Honestly, I shouldn't HAVE to turn off wifi, blue tooth, disable location, etc, etc to have decent battery life! I never had to before this awful Pie update. SAMSUNG, ARE YOU LISTENING??? FIX THIS!!
Looks like THEY are watching ALL the time! They have your irises & your face, finger prints, & probably gait by now, attached to EVERY other byte of data ever compiled on you. Now they are always with you. Listening. Watching. Monitoring all communications. A calendar of your power usage. They are burning up our batteries with the always-on applets...going thru em now & disabling everything possible. There's a BUNCH that are communicating behind the scenes.. And, of course, we bought thru Nazi Bolshevik Commie-cast, sfinity, so THEY get access to the DSPs in the TVs, cable boxes, & voice remotes. Google has @ least a dozen active devices, mostly to ALL w/voice disabled, as much as possible by end user.
same here in Canada ... huge battery drain and some apps not working the same . waiting to hear back from samsung.. Im sorry Im not trouble shooting a brand new phone that had no issues before the update ...
You will be waiting a LONG time! I've fixed mine 100%, Sammy SHOULD have included in their update, either a forced cache partition purge or instructions on how to do it. And they should have optimized the installation of apps included in the update to install them all in a battery-saving state instead of a full-feature state. As installed, every app is fully enabled, meaning no battery saving features enabled. After clearing the cache partition & rebooting, I went thru EVERY app, turning up battery saving, turning off background communications. Now the battery life is better than ever. Google 'S9 clear cache partition'
right after receive pie update, formatted due to significant bad battery life. after approximately 2 month, still bad battery life.
even with adaptive battery on
