IOS15 - how to reset and stop app usage battery statistics

I can not answer why it is not possible to reset the Battery Statistics, just as you can reset Screen Time. However, I can state that so far it is only possible if you reset the entire device to the factory settings or change the battery.

In my last two posts I have attached a link where you can send your Feedback directly to Apple. You get it for the last time here: Product Feedback - Apple

As long as your iPhone is protected with a secure 6 digit code, then I would not be worried. You should also keep in mind that your iPhone only store battery statistics for 10 days.

But we are all different, with different motives for concern. You can send feedback to Apple here:

Unfortunately, it is not possible to reset the battery statistics. This is only possible if you do a Factory Reset on your device, that is - delete your entire device.

If you want this, remember to take an iCloud Backup first:

Usage Time covers talk time for incoming and outgoing calls. It can be useful to reset if you have a limit on your plan with your Carrier, so you can keep track of how much talk time you have spent.

Resetting the battery statistics is not helpful, as you will not get the real picture of battery consumption. Then you actually just hide the reality. It will only make sense if you replaced the battery as I see it.
