I have an A100 that was given to me by a friend. It works fine when plugged into the charger. It says "battery status unknown" in system settings and when I unplug it it dies of course. My friend says that their dog chewed the charger cord so they put it away in the closet for about a hear and recently bought a new charger. This issue has been a problem ever sense. I'm thinking that the charging circuit may have been fried. I'm not sure however if the charging circuit is built into the battery or the main board. I can order a battery for around $50 but I don't want to spend it if it isn't going to fix the issue. I tried to OTA to ICS but it won't start the install without a battery charge at least 30%. I plan on breaking out my trusty multi-meter later today and testing some voltages at teatbpoints in the mainboard. Any other ideas? Has anyone else experienced this issue??

My A100 does the same thing. It started after I replaced the LCD. I replaced the battery with one from eBay, but it made no difference. The charge may have run down while I was waiting on the LCD, but I don't know for. As far the eBay battery, who knows about that. It could be charging circuit, since two batteries did the same thing. But, now that I think about it, the original showed 3% charge for a while which enabled me to move to another spot and plug it back in.

Wish I could get ahold of a circuit schematic for this thing.....I would construct another charging circuit.

Mine did that a while ago, when still under warranty. Sent to Acer, they fixed that charging circuit. Apparently a common problem. I suspect a regulator chip, but it's a guess.

You could honestly just charge the battery sepretly, and I bet it'd work. You could even, if you're talented enough, strap a bigger battery to it and be able to use it for days.

With my A100 not even recognizing that the battery is plugged in, I doubt charging it separately would make a difference. I just want it to "think" the battery is there and charged to at least 30% so I can apply a few OTA updates and acquire root. I don't mind having to use it while on AC power only. I have a Galaxy Tab 2 that I can carry around.

so literally a few minutes ago i plugged in my charger into the wall and smoke came out of the microusb(the one i got with the phone) side and then from smoking went to burning, i just wanted to know if anyone else has had this problem.
Can you tell if the end that started smoking was damaged? Is there a chance two wires crossed causing a short circuit? I have personally not heard of that problem on any phone, but have seen it on miscellaneous equipment throughout my life due to short circuit.
Sent from my SCH-I535 using xda app-developers app
yea
the tip of the microusb is burned and some on the back there is a black burn spots.
USB cables they supply with phones are usually crap. Thanks for the reminder,unplugged mine and replaced it with a good one I got from Monoprice. I'd keep an eye on it though if you use another cable to be sure the charger didn't cause it.
The voltage in your plug might be too high... it could have been a faulty cable

yea im going to replace the cable and the charger just to be safe.
My friend threw her phone on charge for the whole night and woke up this morning to find her battery level low. This isn't the first time it happened either. What could cause this?
P.S. the screenshot was taken right after the phone was pulled off the charger

Try a different charger? Also, if the phone was charged by USB, use the wall charger instead. Some USB ports may cut power when the computer is asleep, etc. For instance, I usually connect my phone to my PC using the USB ports on my monitor (just because they are conveniently located). Those ports get shutdown when the computer goes to sleep, which I always forget.

Well she plugs into the wall, never the computer. And the charger she uses is the charger that came w/ the phone. If its the charger that could possibly be the issue then I'll tell her to get it swapped out at an at&t store but I really don't think that's the issue honestly

Chargers can definitely just crap out, even if new. MicroUSB chargers are pretty common, and I've used ones for other devices (like my Motorola Bluetooth headset) on my One X just fine. If you have another MicroUSB charger laying around, its worth checking (just to eliminate the charger as the cause) rather than having to run to the store.
Otherwise, its possible there is something wrong with the microUSB jack on the phone itself, or some other hardware or software problem with the phone. If the charger is not the problem, backup personal data and factory reset the phone. If the problem still occurs, I'd recommend getting a warranty replacement.

Can you confirm that there was a "lightning bolt" in the battery icon in the status bar? If it's charging, there should be a lightning bolt in it. Check when you plug in the charger and just before unplugging it. If the lighting bolt is missing then most likely there is no current going into the device to charge the battery. It could also be a bad battery if the charger is working fine.

Are you absolutely sure the power outlet was switched on? May seem like a silly question but I've done it before.

Yes there was definitely a lightning bolt when it was on. And is it possible to wipe the battery stats even if the phones not rooted?

Hello everyone,
I purchased a used Blaze a few weeks ago and i can not get it to charge passed 60% even after 1 whole day plugged into the wall and using different chargers. The phone was rooted and had custom mod with android 4.1.2. The battery graph seems to plateau every 5-10% then last night it went from 67% straight down to 45% not a gradual decline and it was plugged in. My question is should I even bother with a battery, reload stock rom, or replace usb port? Is it even worth it? I purchased the phone with intentions of putting it on straighttalk so i like the fact that i do not have a contract but then again i have to deal with hardware malfunction myself.
Thanks in advance!!!

Can I take the USB port from let's say an lg p509 and put it on my blaze?I don't see why it would be a problem

the usb port on the blaze is soldered to the board and would be extremely difficult to do unless you have good experience.
I am not sure if that would work, I think it is $40 for a professional to work on it.
Take into account, it may not be the usb but maybe the cable.

take into consideration that the port itself my not be bad, but the USB board itself, in which taking a board from another phone would not work.

I agree. always try for the cheaper option first USB cables are much cheaper
Apart from that, IF the problem was the USB port and not the board, and IF you had a micro soldering iron, and IF you had the soldering skills to remove the old port and re-solder the newer port without crossing circuits and frying your phone, it MIGHT work.
its better just to buy an OEM replacement USB board and swap them. It will save you more headache and have a higher chance of success.
My gs3 running beans and previously clean rom 7 will not charge using any oem Samsung charger. I thought maybe it was just mine but I used a friends and had the same result. I can plug it in and it will both continue to discharge and occasionally just stop charging.
Now I definitely have a looser port because some chargers are quite loose and I've managed to find one that stays snug, however I don't get why my or any Samsung charger won't charge my s3. If anyone has an idea of what would cause this I'd be eternally grateful. Been Google searching like crazy.

It must have been something that got placed in the charging port inadvertently. Best thing you can do is get a warranty replacement. Or check prices for third party service repairs.
You can try the incipio charge case as well. It plugs into your phones charge port. And has a separate one you can use to charge your phone. Or you can try an external charger to charge your battery outside of your phone.

Hi,
I have had my phone since August 2012. Starting the other day my micro usb port on my S3 is starting to get really picky as to how it must be positioned to charge. I have tried atleast 4 different cables, all doing the same thing. I know its just a matter of time before it stops charging all together...
My question is
A)Is the micro USB replaceable (I have no soldering experience)
B)Should I replace the whole motherboard
C)Should I look for a new phone (I can use my brothers upgrade.... but only as last resort)
What are your thoughts?
Thanks!

I see videos for replacing just the usb part ON the motherboard, some people solder (like I said, I never soldered before)
AND there are some 'unprofessional' looking videos where people use a heat gun (which I have) to just replace it.
As for the motherboard replacement, there are good complete disassemblies of the S3, and some boards can be found on ebay
but for $130...
Well you should be careful charging your phone next time perhaps when you get a new device don't let the charger yank down on the port itself

you could always invest in wireless charging! Then you wouldnt have to deal with it! Could be a good alternative!
I found this:
http://www.amazon.com/SainSonic-Standard-Wireless-Charger-Receiver/dp/B00C3DKSRM?tag=notebookscom-20
and then you can just buy a wireless charger and boom no more worrying about the microusb port!

You could also buy a spare battery and one if those wall charger that you put the battery in (like that come with the zero lemon 2300 slims). You essentially charge the battery outside the phone, then just pop the charged battery in (no touching charging port on your phone). I think they're like 20 something bucks on Amazon and come with that wall charger thing.
