Battery going 90% to 3% in a few seconds!
One year ago I bought an red iPhone 7 in local Apple Store in Florida .
For one month, I got a problem with the battery and it discharges very fast maybe 80% to 90% only in a few seconds.
I tried many things like a restore or install a new iOS, but no success unfortunately
The health check up on iOS doesn't find anything and apple support too.
Does The trouble really come from the battery ?
I'm ready to change it.
Thanks from France
Is dit een goede vraag?
