Hi all,

I have a somewhat strange issue with my iPad Pro 10.5. As long as I use an official Apple charge adapter everything is fine. I’ve found, however, that if the battery gets low and I use my Anker battery pack to recharge it the battery percentage reading becomes inaccurate. The inaccuracy gets progressively worse the more times I use the battery pack to charge it. Recently it became so bad that it would drop from 100% to empty with less than 4 hours of use. I had resigned myself to having to purchase a new iPad when I came across a video recommending battery calibratio. Thankfully this actually fixed the problem. What I don’t understand is why charging via battery pack would cause this problem. Any ideas?

Thanks,
mario
