iPhone 14 Pro: iOS 26 app battery usage chart missing

I got my phone refurbished so it likely has been. Though wouldn’t the app power usage simply be monitoring through just the software? I can’t see how having a non-OEM battery would affect that. I’ve seen this issue with other users as well.

If an iPhone has been tampered with by anyone not authorized by Apple, then it wouldn't have an authentic battery and that would completely explain why battery usage stats are likely not seen on your iPhone. Since we can't know who refurbished the iPhone, you'd need to take this up with whoever you purchased it from.

No, it has not been removed in iOS 26. Have you had the battery in your iPhone replaced anywhere other than by Apple or an Apple Authorized Service Provider?

My previous iPhone (iPhone X) had a non apple serviced battery and it still showed the app battery usage graph. I do not believe my battery to be the issue here.

You're asking only other users on a user to user only forum to guess why you don't see the battery graph on a used iPhone, which was refurbished by who knows who refurbished it. If you bought the phone from the Apple Refurbished Store, it would have come with nothing but authentic Apple parts and a one year warranty.

You also can't compare one older model iPhone with an unauthentic battery to the current phone you have with unauthentic parts.

Sorry, but there's nothing anyone here on this user to user only forum can offer you about this. How long have you owned the phone and do you have any recourse with whoever you bought it from?
