iPhone 7 Plus battery expanding
Any help would be much appreciated.
So i changed a iPhone 7 plus battery for a customer about 2 months ago because the battery would drain very quick and the battery had actually expanding so much that it pushed the screen out.
All has been well until today the customer has called me up saying that the battery has expanded again.
Is this because there may be a problem with the software or something else which has caused the battery to expand in such a short period of time? As i know there has been a lot of problems with iOS 11 with battery issues.
Or is it purely because of the battery that was used?
The battery i used was a OEM battery from a very reliable company.
Thanks in advance
I have changed the battery again for now and will see how it goes, the customer was also using an aftermarket charging plug, so i got him to purchases both a plug and cable off me. So i don't know if the cable or plug does actually affect it but we will wait and see. Will update again.
Is dit een goede vraag?
