Hi, is the charge icon on?
If no, or intermittently no, then the USB port or its soldering is faulty.
If yes, then we need to see current draw measurements to make a conclusive diagnosis.​

Problem: Battery shows 100% always

EDIT: The problem was that the battery driver isn't the best. At 3.99V it switched to 99%. So the problem is fixed now!
Hi guys.
I have a problem wih my Artemis. After flashing the USPL and a M6.5 ROM it always shows the Battery to be 100% changed and doesn't want to charge it. But I'm sure it isn't 100%.
The ROM isn't the problem cause with the device fully of the same thing happens if trieing it.
I tried to flash the SPL back but I only get errors.
Any help would be cool
Thanks

Hi,
Are you sure that isn't the ROM?
however you haven't tried to mount the original ROM?
bye,
Silvio
OK Answer: I'm sure. I tried 10 ROMs (7 cooked, the original, a HTC English original and HTC German Original). I tried 4 SPLs (Both USPLs (Pof, Cmonex) Original SPL and HTC WWE SPL). I tried 4 Radios too. I checked the Battery with a voltmeter several times and I got first 4.17V (seemd to be nearly full then) and second time I got 4.12 (sure it wasn't full anymore). Now I'm already running it in standby with GSM on for 6h and it still shows 100%. So I'm sure it isn't the ROM SPL or Radio.
Only things left are IPL or OEMSPL. Or maybe the Info recieved from the battery.
Thanks for your reply guy.
Any help would be nice.
then you tried to keep the pocket PC on for a day? to me the battery falls below 100% for 6 hours more or less ...
P.S. the battery is a 3.7V... 4.17-12V ...is full!
Bye,
Silvio
The battery is full at 4.2V as written on it. Compared to my Kaiser it sould only have 80% with 4.12V. And yea I'll leave it on till it goes off itself to know when the battery is empty. When it is empty I'm sure I can't carge anymore if it still thinks it is full but for that problem I have a 4.5V AC/DC adaptor to recharge the battery.
By the way which sence do the 3rd and 4th pin have? They don't have any voltage. Are they for the Vibration motor or do they transmit the charging state to the phone?

I don't know it utility...
however happened to me and I resolved discharged, I do not know what else to do...
P.S. when my battery is fully charged 3.9V marks... sorry for my imperfect english
No problem. Maybe I have to connect + to - very short to get the Voltage down. But first I'll just let it lay there in standby with phone on and see how it goes. Then if it goes off I'm sure the battery is empty. then I can start bench the Charging with external system.
That won't solve the problem but then I'll have a benchmark.
Thanks for your infos and tips.
And your English is no problem to me.
not at all
let me know if it works
Bye
Yea I will.
Solution
GO TO REGISTRY
[HKEY_LOCAL_MACHINE\security\ResOver\Bitmaps]
AND REMOVE:
"BatteryIconIdStart"=dword:000003E9
"BatteryIconLevels"=dword:00000065
RESTART, DONE !!!

Hi
if I may ask do you happen to have any better driver or how did you manage to fix your problem as i happen to have the same.
thanks in advance.
Didn't work. But anyway as I said in first post the problem is fixed. The battery has just a very bad voltage curve as i found out using a voltmeter while discharging.
edit:
@mjonase:
I just waited. It takes until the battery is unter 4V. Then it switched to 99%. The driver isn't the problem just the OEMSPL and the battery itself. Just switch on bluetooth and phone and keep the device on. After max 1h the battery level bar will change.
thanks @ChrBeck it seems i gut a different prob altogether mine seems to be a faulty h/w ,charges up and shows 100% if i remove it from the charger the battery drops quite quick, and when i reset it comes back with almost nothing left but when i charge the battery externally it can keep the charge for approx 2-2 1/2 days. so my artemis does false charge ups i guess.
Yea I think it doesn't charge right.
That is a different problem.
WM 6.5 Shady313 ROM (23081 R2)?

EDIT: Try this, Turn off your phone, Remove the battery, SIM, SDCard (ie: everything), Place for 10-15 minutes, then reassemble your phone and try again

It decreased again? Or stayed static? Remember - Charging (even 1%) takes time.
It seems something is broken. :/

Got another MicroUSB Cable? Try with that. If it still doesn't work, I would assume it to be a hardware issue.

Try another USB cable
Sent from my Wildfire using xda premium
I (probably) have the same problem.
Got an HTC Wildfire a few days ago. Didn't come with the original charger & cable.
The charger I got is 500mA. Problem is, it's barely charging and sometimes even discharging (while it's plugged in)
I've installed a couple of widgets to look into it (Battery Mix & CurrentWidget)
Battery Mix clearly shows the phone discharging while plugged in (as a graph), CurrentWidget says it's getting under 50mA (ranging from 15-45)
Right now it's off & charging. The battery was around 13% when I switched it off. Waited about 30 min, then turned it back on, it was at 42%.
I'm trying to exhaust all other options before I go out and get new hardware.
I'm wondering why the charger is only giving it <50mA and wondering if the problem lies with it, the battery, the cable or the phone itself.

[Q] battery problem :-/

hey guys, I noticed a problem about the recharging time after updated LG optimus g to kitkat. now it takes really long hours to charge the phone completely, for example it needs at least 7-8 hours or even more. how can I solve this problem?
I have this problem. Anyone knows something about this?
You should try too calibrate your battery
I'd recommend to use NEMA BATTERY CALIBRATION
Sent from my LG-E975
I also have a problem with my LG Optimus G. I have Android KitKat, software 20C, rooted phone. Yesterday my phone battery dropped to 0%. I was sick and I didn't have time to charge it. Today I plug my charger but nothing happens. LED isn't working (no red colour), there is nothing on my smartphone display. What's the problem with this smartphone, I hope he isn't bricked.

I had the same problem, turns out it was just my charger. After I bought a new one the charging time droped from 7h to 2h.
I have the same problem. I can confirm that the problem is the charger or the charging port or the usb cable socket.

im also starting to notice my phone is charging so slow, the battery icon indicates that it's filling up but sometimes the percentage wont go up, it will be stuck at 50% for couple of hours, and i have read some topics saying that This phone has really some problem burning up the charging ports, one even said that he already burned 4 chargers out of this phone is this true?

No, it's not. Just change the USB cable. If didn't help change the battery. I myself did it vice versa!

i think it's my charger, because i tried my friend's charger from his Zenfone 5 and it charged my phone for just about 2hrs or so.
mine would charge for atleast 3 to 5% and after that it will not charge anymore, i wonder what happened? I am on full stock right now fully unrooted using LG flash tool. it's really a shame that my charger gave up so soon as i have only bought this phone(Brand New) not 2 months ago.

I had exactly the same problem. I forced them to change my main board under guarantee. It didn't help. I bought a new battery. Helped but charging time was 3 hours. I saw I couldn't transfer files via USB tried changing cable and I can charge 0 to 100 in 2:10 hours. 20 mins faster than the day I bought my phone. The stock charger is OK but the cable is a crap. Do what I did from bottom to top!

Help me please!!!!

hi, The problem is that when I do I connect the charger to the phone battery icon shows it charged and then turns off for a moment and then reappear again and stay on this case and when leave it for hours and then come back to him I find deficient battery charge:crying:
please i need a solution ty .

Try another charger to determine if it's the problem with the usb port or the charger.

Battery drain 10% after restart

I am looking for an explanation on my problem. Every time I restart my sm-t520 the battery shows 10% less than before the restart. If I turn the tablet off for about 30 seconds, and turn on the tablet, the battery shows what it suppose to.
Could it be that the connector for the battery is loose or something? It does that on every rom I flash
Same problem on stock?

Yes, but i just took off the back cover and unpluged the battery connector and pluged it back in seems fine now. Don't know what was the problem. I will test it some more to see if its really fixed or just my imagination

Everything seems good since yesterday, tried several times to restart the tablet and always shows good battery percentage. So just unplug and replug battery connector did the job.

So it seems like to be a hardware problem and you nsolved it... But i can not understand how the battery connector should be responsible for draining ...

I bought this tablet used from someone. Maybe this person droped the tablet when he had it and the connector was half disconnected (just my thought). But its running good now
