iPad Pro iPad Pro 10.5 Media Play Duration?

[haralds]

My 2½ year old iPad Pro 10.5 seems to go run down more quickly. After recalibration coconut battery claimed only 64% of design capacity. Running it this morning from a full charge I got 20 min. of browsing news and about 4 hours of playing downloaded videos. Then I got the 10% warning.
I seem to remember 7 - 8 hrs of media play.

Last week I saw an Apple Genius and his diagnostics claimed 90% of design capacity.
I am glad to pay the $99 battery charge but would like my old life back. I will make another appointment armed with this new info.

What play duration are others seeing - new or used? Am I out of line?

Coconut battery isn't always accurate.

Coconut battery isn't always accurate.

Here is the difference in approach as described by Chris Sinai from Coconut Flavor: "Currently coconutBattery reads the “current” battery health as it is measured directly by the battery management chip. Apple in general uses a different approach to measure the health value (of course this shows the best possible health for the battery): they measure the health over a period of time and will lower their health value a fixed amount from 100% when the actual health is below this. As these ranges are quite long the apple health value will need some time to show the actual health value. I can understand this approach as it will prevent statistical error but they should disclose their actual algorithm."

My sense is that Apple tries to have the battery presented in a better way. Given my experience with the reduction in actual battery life, I suspect Coconut is actually closer to what is real.

My iPhone 11 Pro is very healthy with good life and the match with Coconut is closer.
