All iPads Trying to get battery cycles with Coconut battery but access denied. Why?

Installed Coconut Battery on my MacBook Air, connected my iPad Air 3 to it with a USB cable, loaded CB, clicked on IOS Device tab and I get the message: "Access to this device denied. (Please trust this Mac in the dialog on our IOS device.)

But...no dialog comes up on my iPad asking me to trust anything. Would really appreciate it if someone would tell me how I can manually go into my iPad and trust Coconut Battery to pull the battery information from my iPad?

Thanks so much!

P.S. Reason for Coconut Battery: trying to get the number of cycles on my iPad's battery to date.

I'll check my iPad 12.9, I've never used it with CB, so I'll see if I get prompted. My phone is already trusted, I think I remember needing to do the trust process via iTunes[?] I might be misremembering, but try that, unlock the iPad, start iTunes, if there's a trust prompt, OK it, then try CB.

You can find the number of cycles in the system info

Thanks. But I'm trying to get the number of cycles on my iPad, not my MacBook Air. The system info (System Report) you're talking about is specific to the MBA only, not the iPad. But if my iPad has a system info dialog somewhere, please show me where.

FYI, my 12.9 iPadPro came right up without a prompt (but it may have already been trusted (it's also setup as a dev device).
 
Coconut Battery is not reliable for iPads. According to Coconut Battery, my iPad was at 50% health. When Apple ran their tests it was at 87%. Coconut Battery just doesn't have access to the APIs it needs.

What Apple should do just put the battery health meter from iPhone to iPad.

Sare here. CB said my health was at 42%. Apple tested mine to be at 92%, so no need to swap out.
 
Imazing free version works for iPads. I find the information provided is identical to Coconut.

Well good thing my reply was meant for the OP and not you I guess. 😉

My re-ly was also to the OP to point out inconsistencies in such battery “testing” software. If what you recommend is just as poorly helpful that should be pointed out unless you have more anecdotal evidence than “I know of another app.”
 
Your reply was to me....maybe next time don’t quote me if that isn’t your intention My advice is fine.....a lot of people use iMazing and Coconut with no complaints. None of these are completely accurate as far as capacity but I’ve no reason to think the cycle count is wrong which is what the OP is looking for but thanks for the input “professor” :rolleyes::rolleyes:

Accuracy is important if you are deciding whether to replace a battery, swap out a machine, or do nothing at all. Since you can’t provide evidence to the contrary—as I did with Coconut vs. Apple testing—your credibility is questionable and your solution is just a “throw on the wall and see if it sticks” solution—at best.

Maybe next time you don’t have to be so reactionary and actually try to be helpful?

You are now blocked.

LMAO....I know you wont see this but who gives a flying frack if you blocked me? You come across as quite arrogant and certainly not someone I care to interact with. Bye bye Buttercup. Good riddance.

It seems to be reliable for certain iPads, but not for others.

My original 12.9 was off a lot. It was weird, Coconut Battery reported what it felt like: I was getting about half battery life.

That said, the beta for the new iPadOS seems better for battery.

I just wish they'd put that % in iPadOS.

This happens to me when I buy a new iPad and restore from iCloud. Because the iPad has the same name as previous iPad, the iPad or the Mac thinks that it already trusts the computer. I can't remember if I opened Finder, then tried to connect to the iPad or did so with Photos/Music -- but that initiates a dialog to trust the iPad and you're back working again.
