I obtained a used iPad Air 4 off from eBay, for an arguably nice value, however with out guarantee: disgrace on me!
In precept it really works nice, however there’s a factor in regards to the battery lifetime that puzzles me: from the Apple Analytics logfile I learn
last_value_MaximumCapacityPercentage=97
Which appears to point a battery well being of 97%. Additionally a 3rd celebration Home windows Software claims that I’ve a wholesome battery. Subsequently the vendor was proper do describe the battery situation as ‚good‘.
However then, after I first unpacked and used the iPad, I skilled large battery drain even with lightest activity, which was capped after I went to mattress with the iPad in standby at like 2/3 cost solely to get up to a lifeless iPad with a brand new LowBatteryLog-file. I appear to get like 40 minutes of display screen time and 10 h of standby outing of the gadget.
I repeated the method and left it with 100% cost at 11 pm, and now see the cost Evolution with like half-hour of display screen time, and the principle drain app is the House Display screen. particularly over the course of the remainding evening, the battery already misplaced 40 % of its cost
This contradicts my expectations from the battery situation alone, and I’ve typically examine software program associated points which result in exhaustive battery draining. Might this be the case with my gadget?
Does an apparent wrongdoer come to thoughts from my mere description?
Or is the battery nuts and I ought to strive for a refund / restore it / resell it?
Good god, how I wanted to have paid 50 bucks extra to not have this concern 🥲 be smart and study from my silly bean counter mistake
