Does my iPhone battery need replacing?
I just bought an iPhone 6s that has been stored in a drawer unused for about a year. I just did a software update and it dropped from 63% to 35% after it was done. I restarted the phone and it had dropped down to 1%.
I’m charging it now and it is charging very fast - 1% to 40% in about 15 minutes.
Does this battery sound like it needs replacing?
I’ll add that the phone got pretty hot while it was downloading the update but I’m not sure if that’s battery related or just because it was downloading a large file
