Do you have to charge with the Motorola plug? I was just using an apple charger and mini usb from my captivate so I didn't have to open my accessories. Last night my phone froze at 30% (and I missed my alarm) but I reset it this morning and plugged it back in and it was at 100% I took it back and they replaced on the spot. So I ran down the new battery and plugged it in to charge it up and it charged to 30% then a popup came up to disconnect to conserve energy? It wouldn't go away until I shut the phone off and restarted it. Has anyone had a similar problem? Do I just have to use the Motorola accessories?
