I had a similar problem with the Apple Watch and now the Pad Pro sometimes stops charging the battery at 96%. The only way to fix it is restarting the device. It happened with iOS 11.3 and 11.4 did not fix the issue. Any ideas?
Its just a number on your screen and it’s driven by software, like the cellular or WiFi signal strength. It’s meant to give you a rough idea of how much battery remains. It’s not meant to be precise. I find it’s better to turn that stuff off in Settings so I don’t obsess over it.
I just had this issue too. I chatted to online Apple support and they had me run diagnostics, advised that my battery was showing as fine, then told me to update from 11.3.1 to 11.4, then drain the battery completely, then recharge to 100%, drain completely again and recharge completely again. I’m still on the second drain after fully draining and recharging once and I can confirm that my iPad reached 100% and also didn’t drop the first ~10% of charge as quickly as it had for the past week either.
This is BS advice. I can’t believe Apple chat support still goes with this crap. They’re just wasting their and your time.
I’m not sure how it is possible when by definition lithium batteries don’t operate with this crap “calibration” technology.
I believe what you are all saying regarding the batteries, but I really had no choice but to follow what Apple support were suggesting. It did get my iPad to charge to 100% now, while previously it was charging to 93 or 95%. So this leads me to believe that there is either a software issue and my iPad needed to drain and recharge to correct it or that Apple are hiding bad batteries with software adjustments after a full drain and recharge.
True. Is not that rare. Most people only talk theory. In reality calibration still works and is needed sometimes.
You are taking this out of the thin air. Earlier you were convinced it’s a hardware issue. Now all of a sudden you need to calibrate a modern battery.
I had similar problem with iOS 10 and now on iOS 11 my iPad sometimes stops charging at 96%. Its not HW failure. I covered this at my blog at https://comp-blog.com/index.php/2016/12/11/ipad-pro-and-29-w-charger-bug/ - read my update at the end of article from 3rd June.
Yeah just restarting the device is sufficient from my own experience. You don’t need to update/drain/recharge.
Unfortunately, it happens almost on a daily basis, my previous non “pro” iPads never had this problem.
That's definitely a hardware bug then. I would try setting up a Genius Appointment or equivalent to get it replaced.
Just a quick update, I went to the Apple Store today and they gave me a new iPad Pro without asking many questions.
