When I charge the Storm, it sometimes charges and shows the bolt, and sometimes it doesn't charge. I have to remove the charger and reinsert it a few times until it charges and show the bolt.
This problem exists regardless of the charging method...car, wall, or USB.
Last night I was charging on USB cord and I checked to make sure it really was charging. This AM I unplugged, didn't first verify it was still charging, looked at battery charge and I was at 50%?????
You should try a charging dock/pod.
Maybe your ahh! I'm lost with words this morning. The thing you put the charger in is broken. (The one on the phone)
Take it in to the store.
