BB Classic always on battery saver mode

This morning my Classic went on battery saver mode even thought the battery indicator was showing 69% full. I put it on charge and now even though the indicator is at 100% it won't leave battery saver mode. Perhaps the following is related - about a week ago the Classic lost connection with my car and although they see each other they won't connect. Is my Classic dying?

Have you tried simply rebooting the device?

You did try... pulling down quick settings and disabling it right?

Did you check the settings for battery saving mode? Also as the op said check quick settings by putting down from the top of your screen to see if it's set to on.
