Hi all,
i bought a refurbished lg g2, (big mistake) :crying:
i had troubles with charging it (original charger)
battery level wont rise , and if i i close the phone when its in that state it wont open in any chance.
used a app called AMPER to check the current and found out that it thinks that the battery is @ -30 degrees.
does any one know where is the temp sensor , do u think replacing battery can help?
is there any way to cancel the low temp protection which prevent it to turn on?
I would definitely replace the battery. Sounds like it's busted
Not sure where temp sensor is..perhaps on the logic board itself?

I´ve just come back from a two month expedition on Borneo. But when i got back to civilization and turned on my trusty N1 I quickly realized that my battery performance has dropped significantly. Before I usually had one day of heavy use (including Wifi, 3G, tethering and GPS usage), but now I only have about 7 hours standby with everything except GSM turned off. Which renders the phone useless for my (normal) use. The phone actually consumes so much power that the battery level drops while charging. The only way to charge it up is to turn the phone completely off.
I flashed the RoDrIgUeZsTyLe™ MIUIMOD -ROM before I left for my trip, so I thought maybe that was the problem (some bug i the kernel or something), so i flashed back to CM6 with no success. I have also tried a new battery.
Anyone knows what can be the cause?
All help is deeply appreciated --- I miss my good old N1!
I accidentally placed this in the wrong section - can anybody move it to Q&A?
Try the battery app in my sig to pull your battery values, then post in that thread and one of us can help you see what's happening with your battery.
maybe the charger is the problem?
Just throwing it out there... I've seen it happen for Laptop users...

Hi,
I had similar problems with my rooted N1 with stock Froyo.
The problem for me was a radio image older than regular. Baseband version should be something _4.06 or higher.
You can check this information in Settings ->About Phone

I got 32.41.00.32U_5.08.00.04 so it doesn't seem to be old, but I'll try to update the radio anyway with a custom stock rom from modaco. Will let you guys know if it helps
Update: I'm now back at *****_4.06****. No change
My first thought is: what level of power did you leave your battery with before you went away?
Lithium batteries are permanently damaged if the voltage drops below a certain level. Leakage will mean that any battery left for a while will lose charge.
Therefore, if you leave a battery with close to zero power left for a long time, leakage can mean the charge level drops below the critical minimum level and the cells become damaged.
As such, it is recommended to never store lithium batteries with below 40% charge, and to store them in a cool environment, since leakage is faster at higher temperatures.
Yeah, that was my first thought too, since I forgot to turn it off before I left (the phone was stored in a room with AC at least). However, I have now gotten a new battery and it doesn't help...
I have tried to check if there are any programs that are running in the background that draw unnecessary power, but i cant find any ---at least not with system panel. The cpu-load also seem to be normal.
Anyone got some ideas?
Thats really wierd... The only thing you can do is reflash the radio and flash it to stock. Then use the new battery and charge it overnight - so it overcharges slightly. Let it totally drain till the phone turns off, and repeat a coupla of times. Ignore the levels reported by the phone.
See if it starts to behave normally after that. If not you either have another dud battery or there's something wrong with the charging circuit in your phone.
If you have a friend with an N1, you could try charging your respective batteries in your phones, then swap batteries. See how much time each phone lasts
Thanks for the tip.
I'll try that before I buy a new cellphone.
I have tried charge it via usb and regular charger but not working, when i checked the temperature it says 67 degrees, which is a lie cos its not hot at all..So i believe the sensor is broken. Is there a software trick to alter or widen those values to charge the phone cos there is not a security issue?? And where is that bloody sensor on the card i cannot figure it out.... Thank you very much...
I don't think there is any way to test Temperature sensor. So you probably have to go to Service Center.
Other sensor tests can be checked by *#0*# though.
Regards.
it sounds like you should return your phone and get it repaired...
I cannot sent it back to have it repaired cos i have changed its display which was broken, so i need to find a way to alter those charging overheat protection values...
Well if you have a phone with no warranty you have limited choice .
One factory reset that fails flash Samsung stock rom firmware via Odin .
That will rule out faulty software .
jje
am i not clear or i dont know.. Guys temperature sensor thinks that battery is burning at 67 degrees but it is not.......so if i factoru reset it what will change????
sensor is still broken, what i need is somehow disable its overheat protection...
At least you should reset the phone by turning off and removing the battery for a while, it could be something temporarily wrong with the communication between the sensor and the cpu.
have u tried a different battery?

You claim its the temp sensor do you have proof its hardware fault not software fault Putting clean firmware on the phone rules out software /firmware problem but its up to you to go that route or not .

i have tried literally 6 different firmwares and all said 67 degrees and i have left the battery out for almost a day its still the same...
I also have tried a different battery and again it did not charge...But there must be a trick for this, cos the protection, i think, is by software, and therefore, there must be a way to change those values to enable the phone to charge at "67 degrees"...
any solution on this problem?
i have exactly same problem. if you just have the schematics that shows which one is the temp sensor would be great.
I also have the same exact problem. Found this post on google. My temperature sensor shows:
67 Degree on idle
-7 Degree when I attach the Samsung earphones
Below 60 while I'm charging (I would have to stick the cable twice for the charging to work)
Still trying to figure out the issue. Something I have also is that during music playback, left earpiece barely releases any sound. Don't know if its related to circuitry found in the sound jack.
i had this problem a few days ago..
but it just dissapeared after rebooting it think, geuss i was lucky or something
The same problem with a Xperia X8
In my case, my phone drop in water and after a hour of dry the battery sensor going crazy. All functions of the phone works well but the battery sensor start to show elevated temperatures and minutes later extreme low number. After a month the values stop in more than 60c and since then I can't get charge (becouse the policy of the phone to not charge when the battery is hot).
I dont know is the battery but Im sure is not in the battery itself.
The tecnical support of my phone provider (where bought the phone) reject the cell because they are not sure if the changes the will made will be repair the phone. This is because after the accident the garantee is off and if they can't repare the phone don't want be responsible if return my phone worse than the start.
So, my only choise is buy a new ugly phone, wait 4 months to the contract ends and buy a new decent phone with a 12 months plan or... repair my broken phone.
I think if recompile the nAa kernel (my actual kernel) with some changes like hardcode the temp of the battery and install in my phone this will works.
Really I don't know if this is a kernel stuff. I hope, but is this is the case... I never compile a kernel before. I use linux everyday but never mess with the kernel.

maybe its an issue, you should send it to technical support
Hi guys,
My had brother hard a problem with his phone regarding his battery life. He claimed it drained too quick. So he bought a new phone.
After I had "accidendatlly" destroyed the eMMC of my nexus 4 (See this thread) he gave me the phone and told me if I could fix it that I can buy it for a sharp price form him.
I've replaced the battery with a newly bought one online and got the phone out of hibernation mode by connecting it with USB cable and doing the volume down + power button trick.
I've noticed some issues regarding the battery:
- The first time I rebooted it battery life went from 96% to 84%. This was when doing a factory reset (from the menu in android 4.2.2). This has occured once.
- Last night the phone was fully charged so I hooked it off the charger and turned it off. This morning I turn it on and I notice the battery is at 66%. Literally 1/3 of the battery life was lost when the phone was turned off.
Obviously, (I think) there's a loss inside the hardware of some kind. There's one piece of history attached to the phone.
My brother had it one month and dropped it on the floor and his screen was cracked. He then let the screen be replaced by a repair center. They did replace the screen and locked the screws from the battery with some kind of glue (i think) because it was very hard to loosen them.
My questions:
- What could have caused this? Can it be by something done by the repair shop (reversible?)
- In which part of the hardware is this (loss) most likely to occur? Or one can't know this?
- Would it be sensefull to disassemble the phone and replace the screen with the screen from my broken phone (the one with the broken eMMC chip), or is there 0% chance on success by doing this swap?
- Any suggetions on how to tackle this problem or is it just something I'll need to accept. (which is hard to accept, )
Kind regards,
Semi
You should first try to charge it to 100%, then calibrate the battery (there's a little tool in the play store called BatteryCalibration). The percentage values are just approximate. Android knows the amount of mA the battery has when full and constantly checks the current as it drains to calculate the percentage left.
Calibrating the battery basically means deleting these statistic files to allow the system to start from scratch. You may need to do a few discharge/charge cycles until it is somewhat reliable.
If this doesn't help I assume the fault is hardware sided.

Hi thanks for your Swift reply. ive checked the app out and i think it needs root. This phone hasnt been rooted yet so ill Get to it when i get home. Greetings.
I do have the exact same problem (phone was never droped) - see this thread:
http://forum.xda-developers.com/nex...rs-off-charging-battery-t2701353#post57181337
Nexus 4 seems quite vunerable to this though I've not found the cause/solution for this on the web yet.
Exactly the same here: Old battery made a worn-out impression, so bought a new one. Actually tried three different new ones from ebay now, all do the same: They charge up to 4.3V around, and when unplugged drain to 87% in a few minutes, i noticed the voltage going down to 4.0/.1V mostly, too.
The current battery seems ok from battery life, but i want an even distribution of the battery status, no matter the voltages - how can i achieve/fix this?
I've have a zerolemon 7500mAh extended battery. I need to run it completely flat every month to help keep it correctly calibrated. this isn't that easy when 5% on this battery is closer to 15% on the standard one. needing to have it useable makes things difficult, so I'm wondering if there are any mods to files I can make to stop the phone entering power saving mode at 5% and also anything that will let me run past 1% on kitkat..
the later has a module in xposed, but it doesn't cover kitkat.
I'm rooted and happy to do it myself if something doesn't already exist for it..
Are you sure that you need to run it completely flat? The technology inside the battery gets damaged when you run it flat. The normal battery gets callibrated by charging it to 100% pulling the battery out and then charge it again till 100%.
Lion battery's get damaged by 3 things:
- Heat
- Age
- Discharging to 0%.
maybe not entirely flat, but those are zero lemon's instructions..
googled again just now and discovered an app called rootdim mentioned elsewhere. it's primary purpose is dimming but it raises the screen light value just as well.. check http://play.google.com/store/apps/details?id=mobi.pruss.superdim for details...
Hi,
I keep getting a "your device is overheating" and can't run any applications.
Also, I can't charge the phone ("Charging paused. Your battery temperature is too high")
The device isn't hot at all. I installed "Battery temperature guard" and it said the battery is at 90 degrees ..which doesn't make any sense.
I tried a cache reset with factory reset but to no avail.
I didn't try replacing the battery but I doubt it'll help since the battery sensor is located in the device itself.
Is there a way to override the battery sensor? Did anyone run into a similar problem?
The problem started when I was at the beach but I'm 99.5% convinced that not a single drop of water touched my phone.
i9505 stock rom non rooted.
Thanks.
