Not the case for me. Battery and temps are the same as before on my end.I have found the May update to be a huge step backwards from April, I have the QPR3 beta running on my device now and it is far more stable. More acceptable battery and temperatures.
There has been nothing that's not stable in May for me too.
Depends on your ambient temperature if that's normal or not.Phone temperature 38 degrees Celsius when using telegramThe set of applications is minimal) Wi-fi and lte - the temperature is the same (((Probably it's still in the May update._.
I'm sorry, I'm just afraid that something is wrong with the phone. I thought that others also have problems with overheating.
I'd check if something is pinning the CPU in background, could be an app getting stuck or a service.
Could be something else that was introduced in May update and only affects some users and not others.
Check the post here that links how to do this:

In this case it turned out to be Facebook.

Nope, if mobile network has a weak signal it takes more battery (which also causes more heat due to higher power draw), you're entirely correct.2 weeks on the kernel running stock 12.1. Things I have noticed:
1) Battery life is maybe 10% better on average, mostly during standby and heavy usage. There are a few medium use days that do worse, but over all its a bit better. My battery life was already pretty good even on stock.
2) Yes the thermals are better. But I noticed that there is absolutely nothing you can do against 5G or LTE overheating. Using data pretty much guarantees higher temps, but on wifi it heats up less, but my device didn't have much issues.
3) Overall everything is as stable if not more stable than stock, if you have bugs, this may or may not help. Things like the swipe up freeze bug still happens occasionally, as app related bugs won't be fixed by a kernel.
