Posting a list off apps installed on Linus phone could be a start . But from the video, I assume all apps were also installed and configured on the second phone ? Make sure ALL , and I mea ALLL apps are exactly the same. Even unsuspectious things like using gboard keyboard or not can make a difference. For exemple when I get my note 9 I installed gboard and it was getting my phone warm idle. And battery was draining like crazy. Still no evedince of gboard on battery consumption graphs (apparently some apps simple don’t show there for some reason )
it can be also a probem with either WiFi or cellular.
I assume he imports all saved WiFi networks when he changes from one Samsung to another? Ex. From s9 to note 9? That can lead to a lot of problems if there is an issue how WiFi networks were saved. (I’ve seen that happening before )
it can also simply be a problem with celular provider. Were the SIM cards you guys bought for testing from the same network Linus uses?
Going to settings and resetting all network configurations ( there’s an option there ) can solve a lot of these idle heating problems . I would start from there.
so anyway... pretty sure is not a Samsung problem by but something you have installed and how it’s configured, since the same happens in two different devices.
( do you use Samsung account? Have you checked if it’s not trying to sync endlessly and falling (seems to happen a lot for no reason ) .
p.s do you have any sd card on you phone? I once had a problem with note 8 using a Toshiba sd that was making the phone almost burning my leg.
