I just got my Lifeline. I plugged it into my USB to charge and the battery meter was at 43%. It charged to about 49% over approximately 30 minutes. I thought it would charge faster from the wall charger, so I unplugged it from my USB and connected it to a wall charger. The battery meter immediately jumped to 98% charged. I did not use the radio in any way. I only unplugged it from the USB and plugged it right into the wall. Will my battery meter be inaccurate forever? Do I have to send it back? Is there a way to correct this problem? I tried resetting it by pressing all three buttons, but the battery meter just changed to 97%.
