Plugged the charger into my Galaxy S5 last night and this morning found the battery and phone were very hot with charge at 47%.

 

Shut phone down and removed battery and let it cool down. After plugging the charger back in it charged perfectly well.

 

So, that leaves me worried and unable to leave it charging unattended which is a PITA.

 

Wondered if anyone has any clues about this??

Maybe it wasn't plugged in quite right? Try a different cable, and watch it a few times while charging. I'd try charging someone other than in my home as well, or at least somewhere like on a metal kitchen bench rather than in a bedroom.

Just check there’s nothing conductive caught in the charging port.

Was the charger hot too?

Darn, I didn't think to check the charger temperature. Charger port seems to be fine. It has a cover and it worked OK before and after and also no problem this morning.

 

Just really weird and darned hard to figure the logic behind it.

 

I mean, what could heat the battery? It wasn't overcharged as it was at 47% and it charged up to 100% in the normal time-frame afterwards. The only other way it could get overheated was if it was supplying a lot of current. Beats me where the current was going though.

 

Unless it could happen if the plug wasn't seated fully???

 

So, thanks, guys, but I will likely have to live with a mystery (but I hate being beaten!!).

Something maxing the CPU out would be my guess. Have that often on my dinosaur note 4 - even fast charge cant keep up.

You might be right, Richard, as the battery life was noticeably decreasing. I almost never turn it off but since it was turned off after the heating episode, the bty life seems to be better.

 

So, maybe something got snafued, stayed on and chewed current??

 

I will turn it off a bit more often and keep my fingers crossed!

Thanks for the thought, turb. Hope it wasn't that! Seems OK, now.

Another possibility is a faulty battery temperature sensor. Maybe the phone thinks the battery is normal, when it is actually really hot.

Although I think that something maxing the processor is still the most likely culprit.

Also I use a slow charger on purpose for overnight charging my phone. To help keep the phone cool, and reduce thermal stress on the battery. I keep the fast charger that came with the phone in the car instead.
