Hi,
I have an issue with my device.
Basically, when I try to charge it, I get the error that the temperature is too low.
I read that the issue could be my NFC-antenna/wireless charger (which is the same part), however, I can still read all of my NFC cards, so that seems to work fine.
I have replaced the charging port about 6 months ago, and it does not seem to be the issue this time.
When reading the temperature with an app, it says -20 degrees Celsius, so that is obviously the issue.
Does anyone know how I could fix this?
I have 2 friends that repair phones and I'll try to fix it in the next few days and I'll tell you how it ended up. I also read about the NFC module and bad contact in it, but we'll have to see. I'm currently heating it up to see if that works. So far it doesn't, but I'm very cautious not to damage the phone and maybe it's not warm enough.
I had my NFC module replaced... bummer...

Hello,
Unfortunately I do not have any pictures to show the issue so I will try to explain the problem as best I can.
I recently replaced the screen and bezel on a LG G2 (D802) Moving everything accross from one bezel to the other went fine with the only difficulty I had was removing the battry from the old bezel (The battery got a little bent, but nothing major).
After putting everything back together in the new bezel/screen I started getting a strange issue. The phone refused to turn on and if I plugged the charger in it would show me a battery symbol with a thermometer in a yellow triangle. After a few minutes it would then turn on.
When the phone is on, it will charge and work perfectly fine until the phone is turned off next.
Looking online I have read that after changing a screen on this particular phone some people have reported that the battery reports its temperature being -30c.
Does anyone have any idea what is causing this issue, and if it is the battery temperature sensor, where is this located?
Have you been able to fix thi problem? i am having the same issue after changing my screen
I'm having the same issue. sometimes when i'm getting the -30 temp issue, I'd literally bang the phone a few times and it would correct itself. while showing -30 temp it would not charge... with the charger connected, it would remain at the same battery level.
I'd appreciate if someone would find a way to hack the charging function not to look at battery temperature as i'm sure it does. I think this is something that runs deep within the device - not a simple OS parameter since the device wouldn't even boot up if it's "too cold".
not sure what i have to replace to fix this issue. I never removed the battery, the issue started after I changed the screen myself (kept the same chassis)
My Micromax phone(Yureka Plus) has been having a few charging problems lately. First let me list the problems that i have seen, and diagnose it as much as i can on my end.
The battery shows the charging indicator but the percentage doesn't always increase.
When I pull the battery the percentage changes at times-increases or decreases,but this doesn't always happen.
The phone sometimes refuses to charge entirely, and it takes multiple tries to get it to do so.
Also very rarely the after switching off the phone and charging it, the screen suddenly starts flickering blue-and only can be fixed by pulling the battery(Happened twice so far)
It shows particular resistance to increase in charge,especially beyond the 70% range-its practically impossible to get it to 100%
When I connect it to a laptop,it does get recognized and i am able to access the files on it(However there seemed to be problems when using an OTG, cant confirm ATM)
When using the phone while charging it either discharges or remains at the same percentage,usually the former.
Its not a software issue as i havent updated the phone in the past month, and the problems began about 2 weeks ago
I have changed cables,power sources and tried to recalibrate the battery-none of them worked.
The problem may or may not be connected with the following-The day before the issue started i was cleaning the phone using water.
I did find some amount of water in the case, but it hardly was enough and none of it seemed to be there near any electrical components
I cleaned the usb port,battery connectors, pins,and did a visual inspection, nothing seemed out of place.
The water damage indicator of the phone seems to be normal.
However the battery does spin-only on one end though...it doesn't spin on the other end.
Thus i am not sure if its a sign of battery damage or just how its manufactured...I think that swelling should be universal and not discriminate between sides.
Unfortunately i will not be able to give the phone for repair/buy stuff as i am out of town for about a week
Is it just a bad battery or something more serious? Like a problem in the logic board or something?

Also the problem is intermittent-it often reoccurs every few percentages.... and i also rebooted in safe mode to ensure that no third party apps are causing the problem. When the battery goes beyond 70-90% the charging(if any) slows quite often.
Just a PSA for anyone else with mysterious battery drain. I was having terrible drain (I could get 2-3 hours of screen on time in a day) that I couldn't pinpoint. I had been messing around with some new ROMs so I figured that was the cause. Went back to stock, the problem was still there. Rolled back to a previous build of EMUI, no improvement. Installed better battery stats but no wakelocks appeared to be causing it. Finally, I noticed that I had an odd process showing up: typec_port0 (or something like that). Couldn't find any reference to it, so I shrugged it off. Then my USB port started acting up. I would charge my phone, then unplug it, but the charging indicator would remain. I gently bent the board within the port, which fixed that for a bit, but it came back. Rebooting would clear the indicator, but it would appear again when I charged.
So, I finally ordered a new charging port board ($5 or so on eBay). Super easy to swap out. After I installed the new board I was back to 6-8 hours of SOT. I would link to the board I bought, but I don't recommend it as the first one I received had a bad microphone. They sent a replacement, but this one looked much different, though everything seems to work.
Moral of the story is that if you have unexplained battery drain, it could be hardware related.
Have a Sm-T530NU that has misbehaved for a long while, originally the OEM battery was thought bad. Yet after it was changed to a new off-brand battery and working on and off for a year and some, the tablet has started misbehaving again, mostly not charging and turning off alone. And recently has started showing the temperature warning icon while charging while off.
So, I've opened it again and digged down, and discovered the battery connector on the PCB wasn't well soldered, the contacts danced in the pad, so I retouched the soldering with flux and a little new solder and it seems ok (I can recheck again later if needed be), so I tested the original battery with multimeter and seemed acceptable, so I installed the original battery back. Charged it for a while, and, again, warning icon for temperature while off, and it switches back and forth between charging and warning... I turned it on, and it works, but throws an error once in a while about being too hot and closes all apps... this, I think should be something related to cpu heat and not battery one... (also wasnt charging during this). So, I read online that some of these tablets with a modem have a service menu (*#0*#) but of course this one has no dialer, so I've tried several programs to try and get into the service menu, my idea is to see if it's possible to recalibrate temperature sensors, for battery and for cpu, but I've not been able to open the service menu by any means (the last mean I have is trying an intent initiated by am but the tablet is not rooted and there's permission issue for asking an intent of uid 2 from uid 0....).
My questions are:
1) Is it possible to get to the service menu of this model somehow? with or without rooting? Is it possible to recalibrate sensors from it?
2) Should I recheck the battery connector? would a battery "overheat" (caused by a bad connector connection to the sensor cable, or a miscalibration) cause app shutdown during run? or is it related to cpu/gpu overheat? I see some phoen models (S2) can cause this message from torubles with the usb connector/pcb, this doesn't sound too logical on my case, but, is it a possible source of problems for this tablet too?
3) If it IS a cpu overheat (though tablet feels cool to the touch) is there anything can be done to help with this issue? micro disipator maybe?
Thanks for any advice. I'm willing to try odd or hard stuff to fix this.
