Hello, i hope the thread is right , someone can help me for a problem of battery? The phone not start. I remove battery and i saw with multimeter is 2,5 volts (so is very down). Now i try to charge with a external charger (very slow for now), however on the nexus there 4 pin. Someone can tell me the right voltage when plug the usb?? Because i dont understand if the phone charge fine or not

don't bother with the USB voltages. Plug it into a wall and wait.

i have an MDA Vario which doesn't work anymore.
it won't turn on or do anything .
it was working fine before i let the battery run out completely, as i forgot to charge it.
i don't have a proper charger, instead i was using a USB cable for a digital camera which had the same plug that fit in the Vario. it used to charge it when the phone was switched on.
does anyone know how to fix this?
do i have to buy a new charger or a new battery?
thanks.

Search here for the 9volt battery trick. There used to be an issue with older ROMs on like the Cingular 8125 where it wouldn't charge once the battery dropped to a certain point. There was a trick to "jump start" the battery with a 9v battery. Then it would charge again via USB or wall charger.
Once you do get it charged, you probably need to make sure you are on your carrier's latest ROM.
Note that while Razr chargers also use the mini-USB plug, I've heard some of the off brand Razr chargers will not give a good charge to a Wizard.
I used to have a hp pda and left it in the draw for a few months and couldnt charge mine, i had to buy a new battery.
Dont get a Razr charger it wont work.

Another possibility since the battery is completely dead is to plug in a charger (really should be a wall charger and not USB from a computer) and just let it sit for about 5 mins. Then press the on button (with it still connected to the charger) to see if it will turn on. If so it should then charge on up. If it doesn't I'd suspect the battery may be damaged.
thanks for the replies, i'll try the things you said
Strange Question? When my battery dies in the past I used to just plug it into my pc at my desk... DELL T5400... and charge the phone up again.
Though lately I have been using a hard-drive cable and I can't seem to recharge my phone on any pc??
Though I can pretty much download all the information from the phone??
I do have the dutty rom on.... though I don't think that would effect it?
Does any one have any ideas?
Under "Settings -> System -> Power -> Battery",
you find the option "When phone is on, do not charge the battery when connected to a PC".
Perhaps its activated?

If you have let the "battery die" over and over you could well have sent the monotoring circuitry below the charging cutoff point which is voltage dependant.
If the battery still charges from a wall outlet then this is more than likely the case as your wall charger will be rated at 1000mAh whereas the USB port is only 500 mAh max and if you have other devices plugged in at the same time it could well be a lot less and this will now no longer "start" the charging process.
If all this is the case then you have trashed the battery.
If not then charging through the wall socket could partly recover the situation, if you are lucky!
When (if) you get a new battery then keep it on constant charge (wall outlet, USB, car charger, external battery pack etc,etc) as much as possible and try to avoid a full discharge.
You guys are great
Thanks Guys that helped a lot.
I have always been scared of discharging the battery completely, Thank pa49 for confirming that.
I found the default setting for the battery was what jkolner said, Thanks bud .
I appreciate the help
Thats right.. last night i left my Leo charging, today when i woke up i noticed that the battery level was very low so.. i unplugged it and plugged it again, noticed that the orange led wasnt lighting up, neither was the phone charging.
The phone gets very very very hot when plugged to charger or USB port on my computer and does not charge at all.
Tried it all, left it all day long with the battery out of the phone, tried charging without it in.. and nothing..it just gets very hot where the connectors (pins) make contact with the battery.
Now im trying to charge the battery on a cradle to flash it with stock rom and SPL to get it to warranty..
Any of you guys has any thoughts?
I see i posted in the wrong section.
Thank u mod
Do you always charge via usb into pc? Is your cradle plugged into the wall or pc? I don't know if you have done this, probably so, but check in windows settings->system->Power and inside the battery tab see if the "When phone is on, do not charge the battery when connected to a PC" is checked.

Yeah.. it crossed my mind to check for it, and that option is unchecked.
Though the charging "orange" led doesnt turn on even if the phone is off.
I usually charge it via usb->pc, allthough i tested with the wall charger and nothing.
I suspect it must have been a power surge that burnt in some way the PBC of the "charging module..thing"
Thanks for the suggestion
i'd check that none of the pins for the battery are in contact with each other if there is heat in that area.
Ok, I'm assuming then that the phone works, but just has low battery at the moment. If that's the case then it doesn't appear to be the battery or the leads. Any chance it's the cable? That of course assumes your using the same one with the cradle. I ask because my device didn't come with a wall charger, just a usb cable so I had to get a few extra plus a wall plug-in with a usb port.

Yep already checked it..although if it was something wrong with the pins the phone wouldnt turn on.. i dunno

Weird, but unfortunately it didn't. I think being in the US and getting the device from Telstra in Australia may be why I didn't. Well, if it is a hardware problem and you can't get it to charge from the device, I believe you can get a cradle that will allow you to charge the battery independant of the phone. I know it's not the best option on the planet, but it would get your battery where it needs to be to flash and confirm whether or not it's a charging issue with the battery itself.
Come to think of it, this did happen to me several weeks ago. I plugged the phone in before bed as usual and noticed the charging light didn't go on and the battery drained overnight from about 60% to 15%, which it shouldn't have done. Not in standby at least. Soft-reset the next day fixed it. It hasn't done it since. I was installing a bunch of things that evening, which may have been what did it.
I had a same problem with my hd2 and by some miracle and few days of pain
it workd again...and it workd about 5 days and same thing happend al over again...and I think I have solution!
It may be stupid but it work for me...

Hi Folks,
My HTC HD2 Android not getting charged either by a wall charger or usb via my pc... i dont what happened suddenly it got turned off due to low battery and when i pluged it for chrging its not showing orange LED notification of charging. when its off and plugged in Orange LED blinked once and Phone got switched on. And when its connected to PC for abt 3 mins it will show charging and after that it shows discharging and battery drains when it shows it discharging . pls help me out coz i dont want to loose my Leo .
Thanx in advance,,,,
Check the pins at the phone which connects to the battery. Sometimes they are deformed and this cause the charging/not charging problem.
But... in this case I don't think this is the problem, because this problem should not affect direct charging from usb cable.
Anyway check them just for sure!
Thanks VDodi

so if your phone dies how do you get it to charge?

Best way is not to let it run out
However, normally it will have enough charge left once it dies to boot up far enough to start charging. If this is not the case, then you have to cut open a USB cable and use the red and black wires to charge the battery. I have not had to do this and am unsure as to how to do it but there are tutorials. It seems simple enough.

Consider, as was previously suggested, a cable connection issue.
While you do not currently have the luxury of looking at your status icons, I have found that, on occasion, when I plugged in the phone to charge, the status icon indicated a USB connection, rather than a charging icon. Unplugging the cable and re-inserting the cable fixed it.
Note that new high quality cables can exhibit the same issue.
You have nothing to lose... Give it a shot.
Good luck.

Take out battery, plug chopped up USB cable into wall charger, use fingers to hold red to + black to -, count to twenty, battery in phone, phone into bootloader, real charger cable into phone and wall charger, leave 10 mins, reboot into android. (Can charge all the way in bootloader, but it seems slower than when android is running.)

By 'tutorials on how to do this' I basically meant your posts
As previously said if you're using magldr you need to be booted into Android before the phone will charge. You can try to warm the battery up in your hands to squeeze the last bit of power out of it to boot up. Or there are standalone hd2 battery charges you can buy from eBay that charge your battery outside of the phone, they're pretty cheap.

As Samuel said you can charge phone in bootloader. Just try!
Had to buy external charger
item # M00366 this charger was cheap has led's that change from red to blue as the battery charges and has a usb port so you can charge a battery in phone at the same time.
I'd been alternating tween an extended battery and the original when my HD2 started discharging while plugged in. same batteries and nearly a year of typhoon's excellent ROM progression then wham dead batteries....
Replaced the lcd, but before this it was left to totally drain.. now when it's plugged in to the wall it wont charge, doesnt warm up, doesnt pop up on my PC when plugged in.. I have the strangest thought the known issue with charging is happening but because it doesnt have enough power to get to the bootloader i cant force it to power off...
Will connecting a spliced usb cable to the + and - points on the battery and plug it in to the mains work to get some juice into this battery? i know it works for old nokias etc/...
cheers

In most cases it will work. Are you sure your USB port wasn't a part of collateral damage when you were replacing your LCD screen ? If you have a multimeter, just check the connection in the microusb. Probably the charging of the n7 battery may awaken it from its slumber, what else you can try is to use jumpers to connect another battery that you know that is fully charged with almost the same voltage and try to boot up the n7?! Maybe that will help ?
