Hey all, I have had my Galaxy Note 10 for almost a year, and the other day I accidentally dropped it and ever since then I have been getting the message that my phone temperature is too low and that charging would resume when my phone returned to a normal temperature.
So I did some research and found that my phone's temperature sensor is broken and that I would need to get the wireless charging coil replaced as that is where the sensor is located. I also saw that it was a cheap repair and would be covered by warranty. Unfortunately because of the root it would not be covered by warranty and was actually very expensive as the part needed to be imported.
I ran a few tests and apparently my phone is at minus 30 degrees Celsius. When I got a report sensor, it says that it isn't even there. Clearly the sensor is broken. (Look at attached URLs for screenshots)
The strange thing is though, that I can still use my phone whilst it is plugged in. So obviously it can still use power, but not store it in the battery. Because it can still use power and since it is rooted, surely there is a way that I can change the minimum temperature at which the phone can charge? Or delete the piece of software/file that gives jt any limit at all?So I wanted to ask, since my phone is rooted, surely there must be a way I can "override" the error and charge my phone regardless.
So I looked for ways to charge my phone regardless and came across thermal throttling, which I know is dangerous, but surely because my phone isn't actually "low temperature" if it was well managed, it wouldn't be too unsafe? And would thermal throttling even work as I know that it helps to run your phone at HIGH temperatures, but what about low ones?
So the last thing I wanted to say was that with the phone being rooted, is there some app that can allow me to ignore this warning (override it) as there is obviously a file that prevents charging when the temperature is low. Could this file be altered/deleted, or could the while thing just be ignored. Or would thermal throttling work?
Please leave some feedback, anything is appreciated.
Also please link at the attached URLs for screenshots.

If that's the only temp sensor for charging you should have it as it won't shut it down if it gets too hot.
A Li meltdown isn't pretty.
Is the bad sensor in the battery???
If so simply replacing the battery might fix the issue
What is the problem?

The repair centre that I took this phone to said that the MOTHERBOARD was broken. I think they were mistaken as this is not a problem caused by broken motherboard. Research says the sensor is in the Wireless Charging Coil so I might try fix this. but then what is it about the battery? Which part is broken?
And in the meantime is their any way to override this message with a rooted phone (my original question)
It a thermistor on the wireless charging module or a bad connection going to it. A broken multilayered mobo solder trace can be repaired if it's just one trace and it's beginning/end point isn't under a flat pack.

So are you saying that either the connection (on the wireless charging COIL) from the coil to the battery is broken, or the connection port on the battery might be broken? Is it definitely NOT a motherboard issue?
If so does the wireless charging coil/entire phone battery need replacing?

I don't see a listing under sensors for a internal batter sensor... it appears to be external.
I didn't tear it down.
The sensor or connector issue is more likely but not guaranteed.
You could take an ohmmeter to the sensor to check if it's the culprit. It appears to be on the charging coil assembly, right?
If so a cheap fix.

There is only one sensor and its attached to the wireless charging coil, that was the case with the s7 edge back in the day. I see no reason why that would be different now. Its purpose is to monitor the battery and coil temps.
Replacing the wireless charging coil should fix it. You should be able to order one for pretty cheap. its could also just be a loose connection. If your warrenty is void then you might as well open it up (if you have the tools and skill) to confirm the wireless charging connector is seated properly into the motherboard. (since you dropped it, its likely its just come loose)

This could be true if the service tech was mistaken. All the OP knows for sure is the chipset isn't getting the temp data.
A good repair center -maybe- could do mobo level repairs. Sammy certainly could.
Remember no repairman likes an open box special.
The OP can try replacing the coil but maybe no better off if it needs a mobo. In the back of my mind I still wonder if the battery pack has a temp sensor the phone is using as well. I see no indication of that but it seems like a logical place for it especially given Samsung's history of exploding batteries.
If the OP goes for a battery replacement there's much more risk of damage involved.
Tough call.
Note: A high G impact can even break internal IC connections. A 3 foot drop onto concrete can generate sufficient G loading to do this. So there's that...
A good case spreads the G force loading over a greater timeframe and lessens it by absorbing some of the energy as well transforming it to heat.
These are heavy, expensive phones with very little impact protection. Get a good case like the Bolt.

It be a happy ending if so...
and not the first time a repair tech was wrong.
Maybe the OP could try a better repair shop if they don't feel up to using a heat gun and popping off the back panel. This is one of the easiest repairs for these phones but still requires considerable care to do. Depends on the OP's skill level and having the minimum tools required.

Well said
Don't know if this will help but I have the same problem with my Note 10+. Mine has a cracked back cover and the faulty temp sensor issue seems to emanate from this because as soon as I slapped on a back cover, the issue resolved itself. I'll replace the back cover eventually but it seems the loose panel might be the issue.
Good luck.

Welcome to XDA
There's a temp sensor on the wireless charging coil assembly I believe. There are a bunch of ribbon cables as well, one could be loose or damaged.
Rear covers are cheap, replace it before the phone gets severely damaged. Get a rear cover seal too. Water kills phones.
Always keep the N10+ cased or it will get damaged. The Zizo Bolt is cheap, provides excellent drop protection and makes the N10+ easier to use.

Hey guys-- got back from the t-mobile store and they told me the data port is dead (from water damage). It turns on with a fresh battery fine, but apparently I'm getting an error code. That code is probably that the data port is messed up because I can't charge my battery. I'm assuming I have to replace it. Does anyone know of a video tutorial or something that will show me how to do it?
thanks.
the chances of the data port being physically damaged by water is very slim- I think they are trying to tell you the circuitry is faulty. If you had ripped the charger out and bent or broke the port, then I could see it- but water cannot bend or break that way and corrosion is unlikely unless its been sitting a while.
Back to the original subject though, I just replaced a faulty USB port on my friends Moto Q. It wasnt bad, but you need a very small pencil iron (I use a station) and good eyes, otherwise you will bridge the tiny connections and be fubar'd.

Where did you find the port to replace it with...
find a bricked one on ebay or something..or someone selling one with a cracked screen etc...use it for parts
welp, i've never soldered... guess you gotta learn sometime. ports are bout 25 bucks... Guess I have a new hobby. Or maybe I should just buy an external battery charger... soldering sounds more fun though. Yeah, what i meant by getting an error code is when i plug in the charging cord into the cell phone, I get a red light instead of yellow/orange. But, I have to push up on the cable where i insert it into the port to get anything. So, its not dead, but either dying or drunk....... drunk from oil.... which it swam in... and got sick from. vegetable oil, not motor oil... which would be a waste of oil. Anyways, thanks for the replies and if you stumble upon a vid for the dash, please post it. I found some on blackberries, but not an excaliber.
sorry browser problem (double posted)
my friend sourced his usb port from Mouser (P/N 538-67503-1020) for $1.12 each. I still have one (he got a spare) but I dont have a dash to take apart and compare the pins. I assume they are all the same generic port, but the pin spacing could differ
http://www.mouser.com/Search/ProductDetail.aspx?qs=7zcQ9RRVJlhHWuXYKEhKMg==
that's pretty sweet speed. I bookmarked that webpage (dunno why really). I could just always link from here; but anyway, I received a new battery that I ordered before the geniouses at t-mobile told me that a red light is an error code, my old battery is perfectly fine, my data port is broken, and no... a new battery won't fix it. *** what's my point you ask?***
They don't know jack fecal matter. I just popped in the new battery and 1) my phone turned on, 2) my charging light turned orange, 3) my plug doesn't need adjusting to charge the phone, and just now 4) my phone has signaled to my through a pretty green light that the new battery just finished charging.
So, to recap, the guys at t-mobile said my port was fried and that all my problems were due to that. My theory was that oil (and come to find out water) damage caused the battery to malfunction and thereby refused to allow a current to charge it resulting in the errors. Turns out, I was right.
Thanks speed and all for your replies. If I need a cheap miniusb port in the future, I now have a good source. Now, Anyone know if a new lcd will fix the splotchy marks on my screen (look like dark puddle spots). I'll post a pic in a new post in a minute.
Yah you can grab a new LCD off ebay (fairly cheap) and then go to youtube and youtube "fix dash screen" and there is a tutorial on there that will guide you on replacing your screen.
just make sure its the lcd thats the problem- the outer clear part that you can touch is separate, and comes with the case. Mine are scratched to hell on both my Dash's but I refuse to buy new cases to fix them
i dunno what's up anymore
I don't know what to think of this thing anymore. This morning it wouldn't turn on, even though I had the green light on the device as it was plugged in all night. So, I kept fiddling with it hoping it would turn on so I could have ATT do a remote hard reset. Well... it wouldn't cooperate. So, I left it alone. Then this evening I was about ready to bury it and I tried the power button one last time and it turned on. But, the battery was really low and I got the red light again when I plugged it in. I guess the battery got a bit of a charge in itself just sitting there. So, perhaps the t-mobile guys do know what they're talking about. Well... i did actually get the orange light while it was on for that sweet minute, which should mean its charging, but I guess its not actually charging the battery. I suppose the last way to go is external charger. I'll probably pick one up off ebay for 15 bucks.
Hi guys, my OnePlus 3's battery indicator is stuck on 50%. I think I must have broken the temperature sensor on it when I replaced the screen. The reason I think that is because in TWRP, the CPU temperature reads something like 1648375974799 degrees. I think because the phone thinks my its temperature is too high, so it won't charge my battery. When I unplugged my phone, it will run for a minute and it would run out of battery.
The funny thing is, I've just replaced the battery. When I switched it on, it read 90% and a few seconds later, it went back to 50% again. I just wiped my whole phone and it still reads 50% in TWRP.
I've tried looking at the parts list to see where the temperature sensor is but I couldn't find it. Is it on the mainboard or the sub board on the bottom of the phone?
Cheers!
I've had similar issues with the Nexus 5 not charging, which was caused by a fake battery (temperature sensor was always reading -30).
Given you've just replaced the battery, it might be the same case. I would first try restoring the original battery, just to rule the new battery out.

Hey there, thanks for the reply.
My original battery had this problem, so I thought I would be able to fix it by replacing the battery which was not the case. So I'm pretty convinced that I messed up the temperature sensor. Was looking for a way to disable or spoof the temperature sensor, or replacing the component instead of the main logic board which could be quite costly.
I'm having the same problem, I was told it is from damaging a super small capacitor that's really easy to knock off. Located right beside the battery connection plug on the main board. only problem is I can't find what the cap size is, to try and replace it. I located the damaged cap no problem and mine is diffently damaged, cracked right in the middle, leading me to believe the info about it being the problem was correct, but the article never gave the replacement info. Anyone possibly know the info for the cap located right beside the battery plug under the screen connection, bottom right corner on the one plus 3 main board?
There are 3 possible solutions for this issue.
1: replace battery.
2: change the ROM for one that changes the Kernel for a version without this temperature protection.
3: fix or replace the main board.
To fix the main board you need to check 2 things on it.
On the left side of the battery connector (under a double sided glue tape foam), there are some SMD. The lowest two are related with this problem. I fix my board resoldering the one on the right (nearest to the connector). Be aware that the SMD is small and when are desoldered, it gets sticked on the double sided glue tape foam. I took a picture of it, but i don't know how to insert here.
Hi Folks,
I recently dropped my phone in water. Put the phone in uncooked rice for 2 days, removed sim tray, put it under direct sunlight., tried everything I could possible to dry it. After 4 days, powered on the device, it turned on fine and most of the things working as normal. I did a hardware test with *#808# and most of the tests are passed.
But Speaker, Mic (also the headphone jack) and Vibration isn't working any more. I also noticed that it is charging fine but discharging very fast, even the battery stats shows 100 to 70% as a vertical line. So, I guess battery needs to be replaced. Other than that, on normal use it is heating up.
I did some google search and few forums says, the speaker and vibration connector goes under battery and connect to the top of motherboard. Considering battery is screwed up. I guess the connector is removed or damaged may be.
Has anyone faced the same problem before or anyone can advice something?

You can't dry a phone completely without opening it. So if you are upto it, open it up (provided you are out of warranty) and disconnect all the connectors and clean them with alcohol or other suitable liquid, leave it to dry and then reassemble.
It's hard to guess exactly what happened inside, but it seems there are two possibilities:
- it could be that your top (main) board is damaged, which causes malfunction of connected bottom board OR
- you may have damaged both parts of the phone...
Either case, repairs won't be cheap, motherboard is the most expensive part of the phone.
I would suggest disassembling the device and inspecting internals. Corrosion should be visible.
Check some teardown videos (recommend Jerry Rig Everything or iFixit) before doing anything if you haven't yet.

Thank you @Explorer23 and @tnsmani will do a tear down to check for visible damage part if any.
Took the phone to OP service centre, the repair guy opened it in-front of me for diagnosis. The phone was in dry condition but there were traces of water deposits. He checked few things and suggested that needs to replace mother board as there was no signal coming to speaker receiver and this will cost ~17k.
For me replacing motherboard for such a huge cost isn't of any worth.
Any suggestion if it can be repaired in someway or shall I start to think about selling/exchanging it online.
I have a second hand ONEPLUS 3 that has water damage. It works completely except it won't charge. To charge the battery, I have to remove it and charge it in another ONEPLUS 3. I have replaced the battery and have tried another charging port and daughter board.
When switched on, the phone shows 50% battery regardless of how much charge it has.
I have tried various roms, and it has the latest stock Oreo update atm.
I want to know is there any mod to disable this warning that would allow me to charge it? I understand the risks, but would like to try. I saw a fix for a Samsung S3 by disabling a system app, but do not see the equivalent here. Any suggestion is appreciated. Thanks

If the temp sensor in either the battery or BMS is broken, then you should NOT charge it at all. There's severe risks charging a battery that does not know it's temperature.
Go buy a replacement. Anyone that helps you with this is retarded, as helping you 'fix' something that is broken and can potentially cause damage/explode while charging is dumb.

Hey, did you find a solution? I have got the same problem and could only think of the lower logic board to be damaged. I think that is what you refer to as daughter board. Would be very nice if there is a solution to that problem, even if i have to replace several things. Does anybody know for sure where the battery temperature sensor is in a OP3?
Because on my research I have found that the sensor is in the battery itself in some phones. That would make sense but if you say the battery is charging in another phone that is weird....
Had similar problem a few months ago.
The only thing that appeared on the screen when i turned it on was a warning saying "Device Temperature is too low".
Send it to Oneplus an received it working but on the rma service note they said there was nothing wrong with it.
Funny thing is that it came with OOS 3.2.1 when on that time the last version was Nougat 4.x.x.
Try to flash one of the first versions of OOS and see if it works.
Mine Oneplus 3T won't charge as well, "Device Temperature Is Too Low, Cannot Charge" and battery level is always 50%.
The problem is in malfunctioning on-battery temperature sensor, which doesn't report the data and OS handles that as the minimum possible temperature -40°C. OS won't allow charging if the temperature is less than -3°C, so it won't work.
If you use LineageOS and urgently need to use the phone, you can flash patched kernel with temperature protection disabled and charge it.
WARNING: This kernel is not suitable for every day use, you still should fix malfunctioning hardware. Do not leave unattended device on charger, always control it.
Unpack the image and flash it via recovery in image flash mode.
Hi ValdikSS,
Is there a patch like this for the One Plus 6 as well ?
I've been stuck with this issue for a week now and i replaced the battery tried different chargers and leaving it off for days an try again but nothing worked
Thanks,
Same problem in OnePlus 3t I flashed lot of custom os like pie ROM successfully used perfect ,last time havoc os 2.0 official ROM I flashed, one mistake I do,
I didn't see the battery level that time 13% I flashed ROM so battery sensor shows temperature is too low then I charged then I flashed same ROM is done, but another ROM I again flash, that shows battery 50% stuck an I encrypted again OnePlus 3t oxygen os I flashed same problem, finally I used nitrogen an havoc only charge100% but no longer time battery stand quickly battery used without any useage ,so battery sensor where we find only solve this problem
It would indeed be a lot risky to charge a battery which has a damaged temperature check mechanism. It does not warrant trying unstable kernels and allowing batteries to be charged without temperature checks. It is risky enough to burn a house down and it is advisable to just buy a new battery if the phone seems to have a decent life left in it.
Possible Solutions
There are 3 possible solutions for this issue.
1: replace battery.
2: change the ROM for one that changes the Kernel for a version without this temperature protection.
3: fix or replace the main board.
To fix the main board you need to check 2 things on it.
On the left side of the battery conector (under a double sided glue tape foam), there are some SMD.
The lowest two are related with this problem.
I fix my board resoldering the one on the right (nearest to the conector).
Be aware that the SMD is small and when are desoldered, it gets sticked on the double sided glue tape foam.
I don't know how to insert a image, Sorry.

Man, I'm really sorry for that.
I thought that I should give one reply for each question, so the person who requested would receive my answer.
I'm new on Forums and still getting the hang of it.
Does anyone know where they are located exactly on the redmi note 5?
Basically i have a used redmi note 5 global with charging problems and after exhausting everything i can think of software related i'm thinking its a faulty diode so i'm contemplating just cutting it out as shown here https://forum.xda-developers.com/redmi-note-3/help/rn3-pro-charging-charging-board-t3671977
Symptoms are as follows
- phone takes a charge when powered off but is tempremental and constantly disconnects every 15 seconds
- I can solve the above by manually flashing firmware files but then it still wont charge properly in the system OS where again its constantly disconnecting and has to be rebooted before it will accept a charge.
- If i flash a new rom / update the initial problem returns where it will only charge when powered off and i have to manually flash the firmware again.

Cutting The Zener Diode out is not a good idea. The Zener diode takes care of the voltage. The Diode works as voltage stabiliser for interference voltage.
Whats your next thread if you cut it?
"Help me, my batterie is just blown away? And i didnt know why!"
so search for the right diode and replace it.

"Help me, my batterie is just blown away? And i didnt know why!"
so search for the right diode and replace it.

Obviously it would be ideal to replace but have you seen how small the diode is and the circuitry surrounding it? Its no easy task to replace and would require specialists tools and expertise none of which i have.
If you have a method for replacing the diode with a bog standard 60watt iron and heat gun then i'm all ears.
Besides if it blows up i'm really not that bothered. It was a cheap device to fix up for a family member and now that i've established its 99.999% hardware related i've really got nothing to lose.

Oh no, you have something to loose, your or somebodies live. You wrote you fix it for a family member, what is if the member loads the battery over night and than the battery expload? The house stays in fire and you loose someones live. Yust my 2 cents.
If you dont have the equipment, search for a tinny repair store. That shouldnt cost much and of course they found the Diode very quick.

You're right in that sense but really who charges overnight isnt that a risk in itself diode or not... i dont know about others but we were brought up never to leave devices unattended and certainly not overnight.
My understanding was the zener diode in the upper board is more for high amperage chargers anyway so even if it was cut out the bottom one would still suffice for low amp chargers up to 5v.
Besides i'm not even sure if its possible to replace the diode, i cant think of anyone that would have the capability of doing such a job. I know for a fact that Xiaomi wont touch them i read over on the Xiaomi forums that they just replaced the entire board in the event of a diode failure which is no doubt costly and i'm not willing to spend on a device that i'm unsure of.
If it works after being cut-out then yes maybe but as it stands i wouldnt be willing to spend in excess of £70 when there is no guarantee of it even fixing the issue.

I understand you, i wouldnt spend also 70 pounds for the repair of a zener diode. Search for a tinny repair store in your location, most eletronic repair stores have the right zener smd and equipment to fix it for you. We are talking about costs 2 beers and 5 pounds.
The zener diode has nothing to do with the ampere, its a diode to stabilise the voltage, if your charger loads with 13 or 14 volt, the diode cuts it down to the right voltage. So take care, overvolting destroys everything in your phone.
btw, drkDEATH is the right nick for your fix method
