Charging Problems on Sprint Mogul
 

I am a EE and thought I understood battery charging. When I have my Mogul totally discharged, the Sprint HTC supplied charger works fine. When I use a third party charger with an A USB jack and a standard syncing or USB A to USB mini 5 pin connector it will not charge a totally discharged battery. My third party chargers with a USB A to USB mini 5 pin connector works great as long as the battery is initially over 30 %. It brings it up to 100%. Does the Sprint HTC supplied charger use different pins? If so, where can a purchase a USB A to USB mini 5 pin connector cable that would send the 5 volts to the correct pins? Any technical description would be appreciated. Thanks.

I know the OEM charger supplies a full 1amp and many after market chargers do not. Also, with no2chem's new rom it thinks my aftermarket charger (and oem sprint car charger) are computers connecting. It does not do this with the OEM home charger, so there is definitely some difference here.

My problems is only visiable when the battery is "totally" discharged (screen dark). I also have 1 amp third party chargers that did not work with a totally discharged battery. I own more than six third party chargers, three are 1 amp, one is 1.25 amp, most of the others are .4 to .6 amps. When I had a totally discharged battery I only tried the 1 or 1.25 amp charger. I also believe the normal mini UBS connector is a 5 pin unit. What is the difference between a 4 pin, 5 pin and 11 pin miniUBS connector? I beleive the Mogul has an 11 pin female connect that works also with the 5 pin charger connector. I have only seen this problem two or three times. I only get the battery totally dischanged once every other month. This is not an easy condition to view. Obviously the answer is use the OEM HTC charger when the battery is totally discharged.
