Alternative to installing Better Battery Stats as system app

Starting with Android 4.4 (KitKat) Better Battery Stats (BBS) require installation as system app to be able to collect the stats.
BBS must re re-installed as system app after each ROM upgrade (upgrade that does not preserve third party system apps).

I have found an alternative to this - the required permissions can be granted to BBS when it is installed as a regular user app by running these commands in Android Terminal (or ADB shell session):

Code:

---

su
pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS
pm grant com.asksven.betterbatterystats android.permission.DUMP

---

After using these commands it might be required to restart BBS process (e.g. reboot the device). Permissions granted this way will be preserved across ROM upgrades (even across those completely overwriting /system partition).

This has been tested on CyanogenMod 12.1 nightlies (Android 5.1.1).
