My 3gs cycles on and off?

Just replaced the battery and the battery shows 38% of power. It will work for maybe 5 minutes and then cycles off. I have placed the phone the charger and it just cycles off and on. The phone seems to work the short time that it is on.

Is this a good question?

Hey Bob,

It sounds like your battery is dead/dying. If you haven't replaced the battery before, I would recommend trying that. We sell the part here and have a free guide for installing it here.

Hope this helps! Good luck!
