It's a chore to do a reset of your battery stats...just let the battery feature of last 24 hours and last 10 days stats be...(if it's ain't broke, don't fix it )
If you really wants to reset the stats as in something % to zero %.....perhaps have a look at this article..
https://allthings.how/can-you-reset-battery...e-stats-ios-12/To disable the automatic install of apps on one IOS device onto another IOS device, try these steps..
1. Open the Settings feature.
2. Tap iTunes & App Store.
3. Under Automatic Downloads, toggle off Apps.
4. Leave the Updates on....that's for updates to your existing apps on the device.
You can then uninstall the app/s you don't want on that particular IOS device ..
Good luck!
