My brand new iPad Pro shows a wear level of 3% in the Battery Life app. I'm running iOS 10.3.3. My several months old iPhone 7 Plus shows a 0% wear level. Should I be concerned and exchange the iPad, or is this normal? Thanks for any help.
I actually got almost the exact same thing, when the guy at an official apple repair store ran a diagnostic. It said 114% and they said they had never seen anything like that before.As I mentioned (in a more verbose way) in the other thread on this, I actually think the Battery Life app is fairly accurate regarding battery capacity. At least, it agreed with Apple's diagnostic when we recently used it on my wife's iPhone 6, and I think it has agreed with their diagnostics in the past. I'm having a similar issue with my iPad Pro 10.5. I suspect there is something wrong with one or more of the following:
Since I'm still in the return period I'm going into a store tomorrow to exchange for a newer one to see what that does.
- the batteries Apple used in that model (even if it's just the way the battery is reporting its capacity)
- the handling storage of those batteries or the finished iPads they're installed in (i.e., if the battery is fully charged and then sits on a shelf for months, that will harm it, and my unit was made several months before I bought it)
- Apple's diagnostics for the new model (because the diagnostic they did over the phone said my battery has a capacity of something like 115%, which makes no sense and which they had never seen)
My screen crackles as well. When I press a few inches below the front facing camera, and a few inches to each side, it makes a crackling sound.I had the same issue as when mine was brand new it already showed 3 percent wear. Kinda wrote that off as the app wasn’t calibrated correctly yet. Now 5 months later my wear is at 13 percent. I have another small issue with it in that the screen crackles when pressing certain points so I figured I’d exchange it at some point anyway, but this pretty much clinches it.
I think you might be right.I think Apple is using crappy batteries in the 10.5" iPad, just like they did with the iPhone 6s. Before I sold my 10,5" it dropped some 6% and I hadn't used it much. My iPhone 7 is still att 100% some 14-15 months old. My 6s dropped about 10% during the same time period.
And I take good care of my batteries, usually charing between 30% to 70%.
