Apparently, wall-mounted ipads and then leaving them plugged in and plugged in continue to do bad things to their battery and can cause them to swell and remove the screen or break the screen.
There’s now a way to stop this by limiting the iPad’s maximum battery charge and requires iPad jailbreaking (easy if it’s an A10 (x) or smaller device or if your new iPad is on the iPad 13) . x or less) and single mode installation. Allows you to specify a maximum charge level for the iPad.
Jailbreaking older iPads (A10x or smaller) is easy with Checkra1n. All iPads on iOS 13.5 or lower can be jailbroken with unc0ver. It is assumed that there will be a future update that will extend this to 13.7 or less.
Then install Cydia, then from Cydia, add repo udevsharold.github.io/repo/. And inside that repo in the “adjustments” section is a free package called BattSafePro. Install this and configure it from Settings.app
Then you can specify the maximum charge level for the iPad. Keep in mind that iPad Air and iPad Air 2 already have a battery cut-off to prevent old batteries from fully charging, this ban can be explored with the Mac CoconutBattery app or the BatteryLife jailbreak app (from the BigBoss repo).
And yes, if you say you prefer not to jailbreak your iPad because the purpose of having a HomeKit home is to have better security, then this solution is simply NOT FOR YOU. Your concerns are not entirely unfounded. , but MORE unfounded.
