The battery in the Lumia 928 is not removable.

With this device, if you have a frozen screen all you need to do is:

1. Press and hold the power button down on the device for about 5 - 10 seconds

2. Release the power button after this time frame, and your phone should do what we call a soft reset!

Thanks I did that accidentally but thank you for the input

Actually, on the Lumia 928 you need to press and hold the power  and volume buttons down on the device for about 5 - 10 seconds.
