I have a problem in Samsung omnia B 7610.When I plug in the charger to power source it displayed the battery is full.When I plug out the battery is low and uncharged.
it is charging normally via usb .but not able to charge via wall charger. please help
It's always possible your friend's charger was faulty, but in this case it probably has more to do with the battery getting fully discharged. Lithium Ion batteries PREFER not to be fully discharged and work their best when topped up frequently. However, unless your battery flatly refuses to charge, any strange abnormalities in battery life can probably be fixed by clearing the battery log.
please reply now .things have changed and i have updated thread now.

I woke up to find my SDA powered off and unable to power on, which was odd considering it was plugged in to a (Motorola) charger.
Since the orange charge light doesn't come on at all, I suspect it's just a dead battery. I've touched the battery contacts to a battery tester with no response - as if the battery is totally dead, which is promising. However, I can't be sure I'm doing it correctly since I've never tried this on a battery I know is working.
There are 4 contacts on the battery, and I'm wondering if there's more to it - like needing to have 2 contacts touching the positive lead and the other 2 touching the negative lead.
Can someone try testing their battery and see which contacts give a live (charged) result?
Thanks

Normally you shouldn't try to use chargers not designed for your phone. What has probably happened is that there wasn't enough current output in the charger, and it completely drained your battery. Your battery is probably fine. Get a proper SDA charger and try charging it again. You can even take it to a store and ask them to plug it in for 15 minutes while you browse the new phones.
Yeah - I lost the original charger, but I've been charging with this Motorola one (output 5V / 550 mAh) and via USB for the past 6 months without problem. I still think it may be the battery because it was at 50% when I went to sleep.
What are the output specs of the original charger?

The stock HTC charger (model ADP-5FH K) has output of 1A at 5V. But if you had no trouble charging before it shouldn't be a issue, unless the charger/battery is faulty.
If you have a multimeter you can verify this. To check if your battery is charged place contacts in (+) and (-) contacts on your battery and it should show ~3.7V. I just tried this.

Thanks, silencer. I don't have a multi-meter, but I was using the battery tester as a way to gauge whether it was putting out any current at all, and it sounds like it's not. You were testing the 1st and 4th contacts?
I have read elsewhere that if your battery goes below 10-20% you won't be able to charge it with anything but the stock charger, so I think that's the problem, but I'll probably order a new battery as well just in case.
Yes I check the voltage between first and forth contact. What sort of battery tester are you using? Is there a digital read out display?
You can also try a USB to mini-usb cable to see if the battery get charged. From what I can remember USB ports are designed to give 500mA at 5V, but I have charged my phone when it was flat using a USB cable.
To follow-up in case anyone has this problem in the future: I ordered a new original charger (ADP-5FH) off eBay and with it, the phone's orange charge light came on right away and after giving it a full charge my phone is back up and running.
I'm inclined to think that it's not the difference in mAh of the original charger (1000mAh) vs USB charging (500mAh), but that there is something unique to the original charger which can "turn on" the charging when the battery is completely dead - perhaps something communicated by one of the extra pins in the mini-USB connection.
Hi guys,
I know if you unplug a charging phone in and out a lot it kills the battery, however my question is (as this was a big battery killer on my nokia n95) if I plug my touch pro into my pc and it has charged, will it then run purely off external power?
On my n95 it would charge, use a tiny bit of power on the battery and very shortly charge again. Obviously if my battery dipped again by a whole bar id want it to kick in the charger but that was crazy.
I'd like to leave my touch pro plugged in a lot for activesynch etc and charge at the same time so it would be nice to know if it's going to kill my battery.
I find that when the battery is charged the USB power will stop charging it. I charge overnight with my PC off on USB and come back and the full charged status is on.
Your PC should be able to provide 500mA through the port if the Touch Pro requests it, however the standalone charger is rated at 1A (1000mA) so if you are worried about using your device while charging then perhaps use it with the external charger.
I see no reason why your battery wouldnt be charged adequatly by the USB port though, generally you would be using less than your are getting from the usb port.

erm... where did you hear that?
no it doesn't
maybe you mix it with the car ignition eating too much gas if you do it a lot?
Well, it used to be that way with the old NiCd batteries. Nowadays it's not an issue anymore.
My apologies, whilst lithium ion's don't have memory they do still lose overall power by each charge and discharge, even if it's not a complete one.
my 5 years old LOOX 720 disagrees with you
also my 5 year old HP IPAQ disagrees.
battery is as new and i charged it whenever i wanted.
same situation with my HTC Artemis, i bought it since the first day it went on sale and battery is as new!

This issue has come up so many times ..... i post again a link to a website with details on how to maximise a li-ion batterry. It clearly states that it prefers small discharges, with full discharges in every 30 charge cycles.

Running Synergy Rom stock kernal 15 toggle from AT&T
Ran phone till it died last night, didn't start it back up just plugged it into charger, got empty battery pic, went to bed got up 7 or so hours later and phone was only at 84% ? Another odd thing is the way it shows the charging curves on the battery stats graph. https://www.dropbox.com/s/mupjhqpxl5nhg1b/Screenshot_2012-07-26-08-37-42.png
Anyone have any ideas or have the same thing happen
EDIT:
Think I may have figured out the only charging to 84% problem. I forgot I cycled a new non Samsung battery into my phone. Samsung has adopted a 3.8v battery were as most other phones use 3.7v the aftermarket battery is only 3.7v so I'm guessing its not showing full charge because the battery is never making it to 3.8v. As for the odd stats on the graph I'll see if the Sammy battery does the same thing the next time I kill it. Its my understanding that the batteries have their own overcharge circuitry so I'm guessing generic wall chargers will still charge the Sammy 3.8v batteries to the full 3.8v and not 3.7v the chargers I have also lack a voltage rating so I'm again guessing that that is because it is regulated by the battery itself.
Hello,
When I charge my Nexus 5, the battery icon keeps on showing it is charging even so the battery is at 100%. Also my USB charger (not the one LG one) indicates that the device is still charging. Is this normal ? Would this damage the battery ?
Thanks
It's normal.

Thanks ! (But i just find this weird as I expected a device to stop at 100%)
I understand what you're saying but it's not a charging icon, it's a connected to power icon. If you were to use something like the dashclock extension it would show that it actually stopped charging once it reached 100%
Thanks for the reply.
The thing is that I have this charger http://www.portablepowersupplies.co.uk/portapow-quad-usb-mains-charger/) and the LED indicates charging (albeit I did not measure the current ).
Nice unit!
Are you connected to WiFi while charging? I had the really bad battery drain issue while connected to WiFi after the 4.4.2 update. I lost about 30% of charge after 4ish hours while connected. Currently I'm at 92% after 3 hours.
The WiFi battery drain could be causing your phone to not fully charge or at the very least make your charger THINK it's not fully charged. No harm should come of it either way but it's always best to pull your phone off the charger once it gets to 99-100%
Thanks for the reply. I had Wifi activated; it might be the reason.
My wireless charger LED didn't shut off when my N5 was charged in a powered off state. Usually it does once the battery is full.
That said, I don't think it's over-charging the battery, as that would be really bad

Don't worry about it. This isn't the 2000s where constant charging is an issue.
Just tried with the Wifi Off. My USB charger then indicates that the unit is not charging.
Thanks for the replies and great help.
Don't worry about it. The charger isn't the thing that determines how charging is handled, it's all done on the phone side. The phone knows how to take and stop taking power.
In the case of the Nexus 5, it most-likely stops charging the battery but continues using the power from the charger to actually power the unit (thereby no-longer using the battery to run the device, but not charging it any longer).
Hi everybody,
it's a few days I have weird problem with SuperCharge.
I apologize for the lenght of this post, but I don't want to miss any detail that could help in solving my problem.
I recently replaced the battery with a new original one (I hope) bought from an eBay seller.
When I switched-on the smartphone, battery level was 58%. So, I used it normally and, when battery level lowered at 30%, I plugged-in the charger.
Completed the recharge, I used the phone as always.
At night, with 30% of battery level, I plugged-in the charger and I went to sleep.
The next day, in the morning, I turned on the screen and the battery level was 32%. I was confused... So, I un-plugged the charger, plugged it in again and the phone needed just few minutes to fully charge at 100% (very weird).
Then I normally used the phone for the entire day.
At night, with 30% of battery level, I plugged-in the charger and I went to sleep.
The day after in the morning I turned on the screen and again the battery wasn't fully charged. It was only 34%.
This time I unplugged the charger and I restarted the phone. After that, it showed 100%. So, in reality, the battery was fully charged!
This made me think it could have been a software related problem: so, I performed a Wipe-Cache-Partition and a battery re-calibration process.
After that, I noticed the charging process was slower, although the phone shows "Super-Charge" in the lock-screen.
So, I wanted to monitor the charging process with Ampere and this is what happens:
- as soon as I connect the charger, for the first few seconds the charging rises to about 4000mA (as it should);
- suddenly the charging stops, as if I disconnected the charger. At the same time, the battery temperature rises for one second to 44/45 ° C and then quickly returns to 32/34 ° C.
- after a few seconds, the phone starts charging again, but at 1600/1700mA.
- cyclically, therefore, the phone tries again to increase the charging to 4000mA, but, as soon as it reaches the peak, the same phenomenon described above is repeated.
I noticed that the charger overheats while charging.
I replaced the USB-C 5A cable, but the problem persists, so it's not cable related.
If, on the other hand, I use a non-5A USB-C cable, the phone recharges in FastCharge mode (2A) without interruptions and the charger does not heat up.
So, the problem exists only with SuperCharge.
Do you think the charger is defective?
Or is the new battery defective?
I thank in advance anyone who will help me. :fingers-crossed:
I noticed a similar problem with super charge.. When plugged in for charging, super charge doesnt show.. It takes super long to charge to even 50%.. So i tried other cables as well and same issue.. I restarted the phone a few times and then switched it off.. Plugged charger in and left it over night. I noticed the next day super charge was functioning correctly
