To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour
Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well
I can honestly say this works, but I’ve no idea why! It makes no sense to me!
