Lenovo P2 Nougat 7.0 AccuBattery unable to get battery usage measurements

[sling-shot]

After updating to Nougat, AccuBattery application says that it is unable to get battery consumption measurements. It was working fine while on Marshmallow. Has Lenovo disabled access to these statistics in Nougat?

Same problem here,it states "power usage measurements not available".
I find Accubattery figures dubious to say the least, inaccurate reporting of drain missing segments in history tab.
I really only use it as an alarm to charge the phone to 80% to help battery life.
Used it on MM and Nougat.

As a full battery alarm, AccuBattery is poor because all it does is just a short beep.

Go for 'Full battery & theft alarm' which will keep shouting till you shut it off.
Warning - it is full of ads, hence use Greenify to keep it hibernated when not in use.

Hey, did anyone find a fix for this?

Thanks

Switch SELinux enforcing mode to permissive mode, than AccuBattery application will work...
You must install SELinuxModeChanger app to do that... will need root access

Can you help me write policy in selinux to get this app working in enforce mode?
