I tryed 120hz on 720p my phone died at about 5hours but with 60hz lasted 9hours 28 minutes is that normal? This includes playing zero games and on 4g service 5g is off using T-Mobile, adaptive battery, wifi power saving 1MB buffer log size always on display off

Could try putting apps to sleep or deep sleep

From settings > Battery and device care > battery > Background usage limits > sleeping apps or deep sleeping apps

Also I would optimize my battery settings

From Battery >more battery settings >adaptive battery [make sure it is on]

it is all apps are in deep sleeping its been 2 weeks

Then I would suggest you contact Samsung, that's not normal.

oh? people keep telling me im obsessed with it and to leave it alone i still think has battery issues but isn't too bad when on 60hz its improved but i have never hit more than 9hour 30minutes even just doing small things like YouTube and scrolling on social media

These phones need time to learn your usage. Beyond two weeks, I noticed much improvement. 20% battery after 16 hours off charger, of about 70% usage.

Let me search my previous posts ... there's a link to a thread where folks are getting decent battery life ...

If you're quoting screen on time then 9+ hours is good from what I've seen.

2 day battery life is not 48hrs screen on time.  I average about a day and a half before it's down below 20%
