Galaxy S8+ Battery temp -20 celsius.

Hi

My phone says that the battery temp is -20 (tried with different apps )

When I try to charge it says: Charging paused, battery temp too LOW.

I have tryed to change the daughterboard, but still same problem.

Also tried with another battery.

I can't see any water damage.

So I just had this problem. Tried new battery, same issue. But when I completely reassembled the phone (I was testing phone after screen replacement so I didn't have it all put back together when I was having this problem) everything charged find. No low temp issue. Something on the loudspeaker and other parts seem to cause problems if they are not connected. Hope you have the same problem.

Also seen the NFC Antenna cause problems charging with USB, why Wireless Charging would affect USB Charging, dunno, but replaced an S8 & a S8+ Battery, both wouldn't charge without NFC completely installed.

Was that other battery you tested known to work in another phone? If not the problem may be with each battery's on-board Battery Protection Board, not your phone. Try a new battery or a known working one, hopefully that will fix it.
