S21 5g very bad performance in games

[valentin387]

First of all device is 6 weeks old..before last 2 updates everything went great,good game performance good battery life,around 5 hours on screen time..now it cannot play games like mobile legends on low with 30fps ( it runs well for around 15 min and then its just very laggy,I see freezing pictures at times given) i m afraid to try genshin impact or other demanding title.

I noticed another thing,when I m ingame and receive a notification,message or whatever thats when it starts to be laggy and heat up mostly,also there is a blueish edge band when this kicks in (edge notification and menu is disabled)

I have done a full wipe after getting android 12 and cache wipe and clear cache partition,but after the latest update i only done a clear cache partition and I refuse to do a full wipe whenever i get a new update because it makes no sense and don t have the time to do it again and again.

What is there left to be done? Because at this point my old s8 seems much faster in games than my brand new s21..

@valentin387: Regarding your game performance, have you tried heading to Settings > Display > Motion Smoothness > Adaptive, to see if you notice an improvement? If notifications are interrupting your gaming, or causing performance issues, then you may wish to head to Settings > Advanced Features > Bixby Routines > Add Routine > If > App Opened > Game Launcher (or select 'If Game Is Being Played') > Then > Notifications > Do Not Disturb. You could also head to Settings > Notifications, and set this to Detailed to prevent any Edge Lightning issues. Let me know how you get on.

Use game launcher and go into game booster and block notifications I block everything.

Yeah game launcher is good for blocking notifications and phone calls during games.
Downside is if you miss an important call or notifications you had it.

Also look for app updates as lots haven't been working well with Android 12.

The thing i found to make it better is to install good guardians and acces thermal guardian and lift the limit

Your on android 12 that's the problem not all apps games are optimized for android 12 just downgrade to android 11 and your gaming will be fine!

Update.
I noticed after i ve put game launcher to run the games on performance mode instead of optimised there is no need for other tweaks so the problem is mos def a software one,it did took me 10 days to try them all but i finally got it,ty for your tips.

I managed to make it work after raising the temperature to max in thermal guardian but the last update ruined it again,throttling to the max after 10 min of any game or basicly app,been to store they said device is fine or they don t want to fix or swap it
