Charger drains BATTERY!

[BMaster23]

Hi guys,

I have really huge problem! When i connect my htc tytn to charger ( wall charger or usb, same thing) it drains battery ! There is orange light like it is charging, but it goes from 100% to 0 in an hour! Battery works fine... 2 - 3 days... and because i can't charge it over usb, i am using nokia charger, cut the wires, took battery out and connect + to +, - to - and that's how i charge it for the last few days! Does anyone has any idea why is this happening? I have wm 6.1 pays rom i think it is 3.05

i warn angst doing this as this could over charge the battery and when a Lithium Iron or Polymer is over charged they burst into flames or explode and spread nasty toxic chemicals every where. if this be the case it may be time to try a new rom and see if that fixes your problem, try someone elce's charger if this wont fix your problem it may bet time for a new mainboard as these have the charging circuit built in

lithium rechargeable are compact high energy storages devices, and if not charged properly become dangerous

I had charging issues with my 8125 - it would charge with the charger, but when I unplugged the charger (it would read 100%, say I charged from 52% to 100% or something), it would drop really low to like 25% or 23% - sometimes it dropped all the way, and I could no longer get the battery to charge because my travel charger was 500mA and the original charger was 1A - it didn't have enough power.

I had to give it a boost by using a 9V battery and twist ties - touching the battery like you are doing here. I did it for 15 seconds a couple times, popped it in, and it had enough juice to start charging. However, I wouldn't want to do this too long on it as the battery got warm pretty quick and I saw a glimpse of smoke at one point.

After being cautious and not letting it lose charge all the way again, after a few charges it seems to have improved. It no longer drops battery power when unplugging and seems to work as it should.

Not sure if yours drops when you unplug it like mine was, or if it steadily drains while plugged in. Anyways, I thought my charger was just wacked, but it is working fine now after a few charges and being careful and keeping a close eye on things....I also thought it was the battery, but I ordered a new OEM battery, popped it in, and when I unplugged the charger that battery dropped and lost power as well. Now I have two batteries and both seem to work ok, but I did have to play around with them a lot and it did take a few charges before they started working like they should again. I'm not sure what was going on, because it couldn't have been the battery (I replaced it with a new one), and now the charger is acting properly.

Granted, this is all with an 8125 which is older, but there may be something in common here. All I know is it does seem to be fixed and it didn't require any additional purchases or replacements.

sounds like the charging circuits are wacked, this could be caused by dry joints on the charger "smart" chip, but a little heads up with Li-Ion, they don't like gettin wet, (sweat included) once they have been wet they become a fire hazard, (ultramag69 help me out here, remember that one you gave me that was full of mud?!?).

they also don't like going below their threshold voltage of 2.1v per cell, (i think 2.1 for now) after that the battery becomes a resistor and is not worth trying to shock back into life with a 9V battery, as these have a protection circuit built in, as well once in this state they become another fire hazard, it may be worth buying a cheap $30 butane soldering iron with surface mount attachment and just going over some of the areas located round and on the opposite side of the battery, every thing under the silver covers is RF shielded and not worth trying to reflow.

just don't keep the heat on too long, as you may and will desolder components on the opposite side of the board.

other than that if the charger is giving +5 volts respective to its ground, its fine, the difference between the 1A and 500mA chargers is the rate at which its charges the battery, slower is better for Li-Ion due to battery construction for the life span of the battery (if you get more than 6 months out of one your doing good by manufactures standards)

heck even try checking the phones USB connector, it may be stuffed or shorted
