iPads don't meet battery specifications. May you share your battery health and cycles?

    Prompted by the recent thread asking about battery life issues for the iPad Pro 10.5, I am noticing a significant pattern with the newer iPads: They don't reach Apple's battery capacity specs (1000 cycles with 80% capacity remaining). Not only that, they're kilometers away. I have seen it since the Air 2 in hundreds of numbers shared around the entire forum.
    I will start with my own iPad: it is an iPad Pro 9.7 running iOS 9. It has 91.2% capacity - as measured by Coconut Battery, yesterday - and it has 312 cycles. That is the same capacity my iPhone 6s shows... With 330 cycles. Battery life is great because it is on iOS 9, but that's not the point. Almost forgot: a family member's first-generation iPad Mini, 511 cycles, 81% capacity; iPad 4, 530 cycles, 77% capacity.
    I will also offer another example with the iPhone: my iPhone 5c has 83% capacity... And 750 cycles. Exceeding Apple's specs. To conclude, I would like to say that I know that there are a lot of factors that can and do have an impact on battery health, but I have seen a pattern - what's more, I don't think I remember anyone saying that their iPad was with 500 cycles and had 90% capacity - and I would like to have some more results. Thanks everyone.

    I tried to search for coconut battery. I cannot find it on the App Store, which battery app shows your cycle history?

    I've got an iPad Pro 10.5 and 9.7 here.
    10.5: 57 cycles, battery is at 98.7%.
    9.7 is at 177 cycles, 90.2%
    It definitely doesn't seem like the 9.7 is going to be anywhere close to making 1000 cycles at 80%.

    You guys are posting off a tool Apple doesn't have and until you get to the 1000 cycle count or the 80% mark it's guesswork. Yes it looks like it may trend that way, but you can't say for sure.

    I'm not defending apple because I don't think they are alway straight with their customers. But, I also know their rules are always somewhat flexible if you get the right manager in the right mood. They can and often do make exceptions to their policy for customer good will and service. If it's that bad, take it to the store or call and speak to their managers.

    I'm not criticising Apple in any way. I just wanted to know what other members were getting. Also: the iPad Mini and the iPad 4 I referenced are definitely not up to spec. The rest, I seriously doubt it. Yes, it can stay at 90% for 300 more cycles, but I doubt it. I just wanted to know - as I noticed this in a lot of cases - whether people saw the same degradation I did, to see if it was somewhat normal.
    Also, I said that battery life is impeccable for me. Perfect. That iPad 4 I referenced? 14-15 hours of on-screen time. Amazing. With 77% capacity. I'm not complaining about it, and the real world implications of this reduced capacity are, for me - until now - nearly zero. I was just curious, because every single iPhone I have seen is up to spec.

    You can't say those two iPads are not up to spec until they reach 1000 cycles. I'm sorry. That's the way it works. It's not a linear system, and those "measurements" are really just estimates. That's why you can't even draw a conclusion from the 77% iPad 4, let alone from the fact that it's six or seven years old. I'd say that a seven year old battery maintaining 77% of its original capacity is doing a darn good job.

    I disagree, because they almost surely aren't up to spec. Yes, I can't say that the Mini isn't 100%, but I can say it with a large enough certainty. The iPad 4 is already out of spec. I know they aren't linear. I know they are estimates. I just say that the possibility of the Mini being up to spec is really low. I say the possibility of an iPad Pro at 90% with only 177 cycles being up to spec when it reaches 1000 is minimal.
    Estimates or not, they are used everywhere here to take responsibility off of Apple of the awful impact of iOS updates on battery life. "It has 82% health, the battery is gone, that's why you get 4 hours on an iPhone 6s on iOS 12". Estimates or not, they are somewhat meaningful, because I have seen a small battery life drop when capacity decreases. I have seen an iPhone 5 with 950 cycles and capacity jumping between 38% and 50% with an absolutely pathetic battery life. They have some usefulness.

    My iPad Air 2 battery is in bad shape. I didn't need an app to tell me that, I knew. Took it into the Apple Store intending to pay for a new battery, they checked it out and said it wasn't bad enough to justify taking my money for a replacement. I don't know what they used to come to that conclusion. I got home and hooked it up to Coconut and it's knackered.

    Waiting on the new (March?) iPads and I'll trade this one in.

    If you want, you can check your cycles and battery health to see if it's up to spec. If heavily used, an Air 2 might have 1000 cycles.

    I save on battery cycles and keeping my battery healthy by having my iPad mostly plugged in. The battery gets used to keep it healthy. I usually charge when it reaches 85%.

    Sorry, but is that not exactly the point? I’ll be honest, I don’t really give battery health a second thought these days unless something is clearly wrong with it.

    I remember times when there have been issues with Apple batteries and the battery health was a very important metric to look at, but things have moved on so much since then. The cycles thing is just an estimate right and I’ll be honest, I think we have a second gen iPad here which the kids use for videos and some apps and its battery still lasts longer than I could have imagined despite the 7+ years of use.

    I’ve said it before, but there’s too much (mis?)information out there these days when it comes to technology and I often get the impression some people spend more time trying to find fault with their device than just actually using it and enjoying it.

    You are absolutely right. I am not worried or overthinking it, I'm just curious. Also, yes, battery life is what matters. I said it before, it was just curiosity, mainly because the iPhones are almost always up to spec.

    Do note that 2 years is specified along with the 1000 cycles and 80%. Batteries also lose capacity as they age.

    Yes, but iPhones older than two years are within specs. A lot of them, I've seen. And it isn't that iPads are close to spec; or at least, close enough for me to say that the difference is due to age. They're too far from it. I don't know. Perhaps Apple's spec is wrong for the iPads. They get it right on Macs, though.

    It's the same for portable Macs: Who on Earth is able to make 800-1000 battery cycles to this devices? Not even using them every day.

    So that condition of 80% within 1000 cycles is impossible to be met within the 2 first years.
