Galaxy s8 battery swelling

[mark7914]

I have an 18 month old S8 where the battery capacity is only about 80% of factory specification and that drop is really noticeable to the point where I'm going to have to pay £74 to get a new battery put into it.

Forcing that "repair" under the Sale of Goods Act in the UK (merchantable quality) free of charge wouldn't be straightforward.

I'm holding off to see if the battery in this one is going to try to escape from the casing meaning I won't have to pay for the replacement.

Theories about this "exploding battery" problem seem to link back to the 'Pie' update. My S8 has never had any updates, and still runs Android 7 (my choice, deliberately) and rarely gets noticeably hot so there might be something to this theory.

Bought two of them when they first came out
Am now in third battery for both of them
Battery still works swollen but might catch on fire if I wait to replace them.Use mainly Samsung wireless charging system which has own cooling systems. Samsung claims it is my fault. Same problems as older ones except so far except it hasn't exploded yet. Seems Samsung is just hiding facts again.

I got no response or only "it could'nt happen" from Samsung until I posted on Twitter. (search on Twitter..SAMSUNG COMPLAINTS).
I had to replace battery, back and screen.
Now, after Pie I have other problems, also with unsatisfactory response from Samsung. If this is coercion or planned obsolescence, its not working toward another Samsung.. too much money for too many problems & too poor support.

I am in the same position, my phone is around 18months old and has just started behaving very badly on battery power, won't charge fully and discharges rapidly, then wouldn't sit correctly in the case, noticed a crack on the bottom of the corner although it had not been dropped, then noticed the back was popping off just like the rest of you, I can see the battery slightly, it is definitely swollen! Spoke to Samsung on Twitter, Rachel in customer services called me today and they are collecting it tomorrow!
Will see what they say and let you all know.
