Hello,

Have a HTC 6900. Put a new battery in it and it would start at first and run fine. Problem is it's constantly flashing a yellow led (alert) and won't charge.

Wondering if there's any way to view what the alert msg is?

I know it's possible it's a bad a battery. I pulled it out and jury rigged it to a 3.7v charger. Charger is showing it's charged, but when I put it back in the phone it does run again for a while, but still flashes yellow and doesn't charge (also only for about 15 min, ran for over 2 hr when first put in). Also checked voltage 3.6V showing on multi-meter after the jury rig charging. .1 low.

Tried desktop, car, and usb chargers.

Wondering also if there's anything I can test with a mult-meter to make sure the battery meet's specs to kick off charging. Know that 6900's and others are prone to if battery is to low they won't kick into charge cycle.

At this point, not 100% sure if it's the battery or could be something additional to phone. At $30 a pop locally, get's a little expensive to try the replace battery route again. Already tried returning this one...Best Buy wouldn't take it back. grrrrr.

Also, anybody know what all 4 pins to the battery are? Pos and neg are outer, but what are the others for?

Thanks for any help!
