Igen, a telefonnal való engedélyadás kimaradt. (Nem gondoltam, hogy ilyet kell, de most is tanultam valamit. Mert olvasni olvastam, de valamiért nem néztem meg...) Most megadtam az engedélyt:

C:\Program Files (x86)\Minimal ADB and Fastboot>adb -d shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS
Security exception: grantRuntimePermission: Neither user 2000 nor current process has android.permission.GRANT_RUNTIME_PERMISSIONS.

De valami más baja van.

Közben meglett: be kellett kapcsolni a az USB hibakeresés mellé az USB-hibakeresés (Biztonsági beállításokat) is.

Nos, mégsem lett jó minden:
C:\Program Files (x86)\Minimal ADB and Fastboot>adb -d shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS
Exception occurred while executing:
