I have a 1G 12.9 iPad Pro with AppleCare that runs out in June. I have a battery life app that reports 86% capacity now.

I downloaded an app on Mac and that reported cycle count 156 design capacity 10088, full charge capacity 9100.

Just wonder what this seems like for the age etc of it?

Apple says the below
iPad Owners
Your battery is designed to retain up to 80 per cent of its original capacity at 1,000 complete charge cycles.

So it seems I’m pretty close to 80% but only 156 cycle count? I’m just wondering if I took it in to Apple and said battery life seems a little low, they’d see the same details as above and agree? Just with AppleCare running out to get a new battery before it does!?

Thanks

Apple won't replace it unless its under 80%. Batteries are finicky, could lose 5% over ten charges then hold that amount for 600 more charges before degrading again.

Seems pretty good to me, when I had the 12.9 1'st gen my battery life was absolutely horrible 3-5 hours usually, sold it after about two months months with 250+ cycles and upgraded to the new one for better battery life.

Definite? So I need to try get it below this before June then!

Surely they could run a test though and make a call on individual case by case?

Just seems low max capacity to me already?

Batteries currently are a pain. The restrictions of our current ones hold our society back in many bigger ways than just cell/tablet life. Every battery will wear slightly differently. Some will drop fast, some won't drop at all.

My MacBook Pro fell 12% within 300 cycles, I am now at 583 and it hasn't fallen since. My friends 2011 MBP has 690+ charges with 99% of its capacity.

I agree battery is different, just put coconut battery on and says the below. I think its wearing, but are Apple solid on the "its more than 80% too its fine, go away!" ?

How's your battery life on the new one?

I think the contributing factor is the usage under extreme temperatures. As I was able to see your battery temp was 17.6 Celsius and I assume you use it outdoor where it is about <10 celsius? Lithium ion batteries tend to not retain its capacity under very cold& hot temperature. Also, do you always consume your battery to under ~20 percent before charging? That may contribute to it as electrons tend to leak when the percentage is always low.

Going to a centre which has an Apple store and appointments are available. Do you think it's even worth me going and at least trying to get a new battery? Do they do these on the day or not like iPhone battery replacements?
