Question Phone still not charging despite changing usb c daughter board - Redmi Note 10

I have a Redmi note 10 4g and it fell 2 weeks ago. After that it stopped charging, i could fiddle with it by plugging it in a few times though and it worked again for about a week. Mind you, nothing is broken as seen from the outside. Last week however it fully stopped charging. I could still completely use the remaining 80%. I fiddled alot and even cleaned the usb c port but nothing helped and eventually the battery go empty after using it. It does not detect the usb c at all. After that i ordered a phone repair tool kit from ebay for 11€. i opened the redmi note 10 4g from my sister (the phone has a completely cracked screen), took the usb c daughter board out of it and swapped it with the one in my phone. Despite this, my phone still doesnt charge. I could still see the empty battery logo when i long pressed the power button after the repair, so im fairly certain i didnt break anything on my phone.
So, is there any other thing despite the usb c daughter board that could be broken, causing the phone to not detect any usb c despite working otherwise?
Btw, I also did see the daughter board for 1 € avaivable on a website but i didnt want to wait for that, and the one from the other phone should be working

The wrong replacement part.
The battery has failed.
Loose or broken connector or ribbon cable.
Mobo failure.

Thank you so much, i just changed the main ribbon cable and it seems to be charging now! Thanks for providing all of these potential issues, luckily my problem was the easiest of the bunch to solve

Yay! You're welcome.
Anytime you're inside and the battery is a year or older it's a good plan to change it out.
If the battery has reached 80% of it's original capacity it's degraded and should be replaced before it fails. Any swelling is a failure, if so replace it stat before it destroys the device.
Erratic fast charging is another sign of a battery failure.

[Q] How to fix battery over voltage?

My battery's been on the fritz for the last days now. Whenever I turn my GS2 off, it will shows tha battery charging screen, then flash to another icon that shows a battery, exclamation mark in a yellow triangle, and a thermometer. It had to plug the charger in to get it to turn on, even though battery was at 100%.
So, I decided to download Battery Doctor to check my batter stats, and it says 'Health: Over Voltage'.
Does anyone know how to fix this? Help would be much appreciated.
I have exactly the same problem. I have not found a sollution, am thinking of calling samsung and explaining the situation. I will post here if i have a sollution.
What OS version are you running?
What Kernel version are you running?
What carrier (if any) did you purchase the phone through?
I'm on 2.3.3 (KE7), using Chainfire's kernel. Phone is carrier unlocked, unbranded from clove.co.uk.
Btw, I think I may have fixed it. I discharged the battery and used a charger with a lower voltage output to get it fully charged. (Charger I used if from my spare phone, a Samsung Champ). It now says that my battery health is good.
Now, the problem is that my phone won't stay powered off when I turn it off. It will stay off for 1-2 secs and power back on. Even if I remove the battery, the phone will power on after i place the battery back without me touching the power button.

I have the exact problem. Is the battery health still good? I would like to fix this by myself and not send it in and be without my GS2 for that time.
You should try this:
1. be sure, that your battery is full (charging over night)
1. run the app battery calibrator
2. unplug charger
3. drain battery all the way down till it shuts off
In this way your phone can remember what is 100 % and what is 0%
My sgs2 shows 4,194 V at 100 %
I think your stats (look into battery calibrator) said that 100% are for example 3,8 V
PS: You need root permissions
---------- Post added at 04:55 PM ---------- Previous post was at 04:49 PM ----------
Please post us your current voltage.
I have this exact problem. Battery Calibration is pointless, we all know that.
Did anyone ever find out if this is fixable, or do I have to contact Samsung for a replacement?
It's quite annoying that I can't turn off my phone, it just powers on after about 2 seconds. In addition, I never know how much juice I have left in the battery as the reported capacity can jump from 90% down to 6% in an instant. After a reboot it might go up to 12% but I can still use the phone for hours without it shutting down...
Yeah
I've been having the same problems as all above...
Galaxy S2 on Sensation rom, but its not the rom, i flashed to another and the problem still remains...
It all started with phantom charging...(charging when the charger is not even plugged in and constantly making the "charger connected" sound)
I got the phantom charging fixed by cleaning the charger port with a cotton bud and some cleaning alcohol...But now i have overvoltage...
And just like the others, it'll stay on for example 100% and if you reboot its suddenly on under 10% and slowly works its way up to 20 or 30% without even being charged.
I'm assuming the battery got messed up during phantom charging, in tthis case calibration doesnt help, nor does flashing another rom. Flashing another rom leaves the phone stuck in MTP mode therefore unable to use it as a flash drive.
A vid on youtube reccomends replacing the part of the circuit board to which the charger port is attached and as well as the battery at the same time as the battery always gets messed up with the overvoltage issue....
When i have overvoltage i cannot charge even when its under 10%, unless i leave the charger in and reboot the phone it will then charge once it comes back on and it even says GOOD HEALTH until i unplug the charger.
I'd really like a definite solution to the overvoltage issue...
Bump!
Did anyone find an answer to this problem? Mine has started exhibiting the same behaviour. I haven't been able to search out any solutions...
Cheers, PF.
EDIT: Whoops! Just realised I'd better change that signature to SGS2-able. lol
I am also seeing the same issue for the past 3-4 days, I have switched off the phone and took out the battery, planning to visit samsung support center.
I hard rebooted the phone(which reset it to factory) that did'nt help.
will update once I get more info/help from Samsung support.
Vikas
i had the same problem as you guys and i fixed it by cleaning the contacts on the phone where you connect the charger. use some cotton buds and a needle and some alcohol and clean all the contacts at the bottom of the phone (usb cable slot).
make sure phone is turned off tho whilst doing it. that fixed my over voltage issue.
Hi Guys,
I went to Samsung Mobile Support Center today, they told me that USB mini port has turned slightly green, which means that it has in contact with Water
this will not be covered under warranty and might need to be replaced with charges
Tomorrow they will tell me the exact cost.
I still believe, its not an issue of Power port but with the battery port.
will update if I am able to get it solved.
It's a problem with your usb charging port. The only way to truly fix it is to have the charging port plus circuit board replaced. Happened to me a week back and I tried virtually everything- stock roms, removed root, replaced batteries etc. None of that worked. Some posts said it was a port problem. Went to a tech guy I knew and he confirmed the issue when he disconnected the port. It was relatively cheap for me to fix but some people have climed that samsung charges a large amount to fix it. You're better off trying to get it fixed on your own. If you're on warranty, try and claim it.
Also alot of people are having this issue- yours is about the 5th topic I've seen about this problem this week
Hi Guys,
My problem is solved. Samsung support replaced charging port and the chip it was in(total cost 650/- INR, about 13$)
now phone is working as before.
i have the same problem on my gs2, so can i fixed this problem by cleaning the mini usb port?

Cleaning the usb port will/might help with phantom charging , but not overvoltage.....
For Overvoltage you may need to replace the whole USB port part of the circuit board (easily obtainable on EBAY) and you have to replace the battery at the same time as well cause the battery (also easily obtainable off ebay) gets damaged with the overvoltage problem.
I have ordered both about a week ago, awaiting 3 weeks for it to arrive to my country.
Good luck with that...
Theres videos on youtube of how to do the repair for overvoltage yourself...
Will report back here if circuit replacement worked for me...

When you open your s2 for the first time it is tough, but after that it is very easy...
I have already opened mine before to replace the loudspeaker, so it is now easy for me.

That is the part you need to replace, the USB FLEX CABLE...(its the ribbon cable and the board, but they call it a flex cable)
Hope they help you.

[Q] Interesting charging problems on my 4.0

Hey guys, it's been awhile since I asked a question, but here I am, lol.
In a nutshell, I'm pretty sure something in my device (hardware) is fried, but I thought I'd see if anyone knows better.
The problem is my device seems to be sending power out of the usb port, and doesn't connect to the pc or recognize it is charging correctly.
This also applies to download mode (windows says device has malfunctioned) and when powered off (there is no battery that shows up when plugged in). In order to power back on after turning it off, I have to remove the battery, then reinsert it while holding down the power. I can't think of much that could have caused this, other than I was visiting places with high humidity levels. One unusual thing that happened before this started was my device rebooted into safe mode when playing bad piggies. That was really weird since I have tried booting into safe mode before, but thought samsung must have disabled it for some reason. I have already tried wiping data and flashing a new kernel/rom. Obviously I can't re-partition since I can't connect to my computer in download mode. What do you guys think? I think it is time for a new device.
EDIT: I should mention that it started behaving normally yesterday for about 5 minutes, but then it went back to this.

I'm 99.9% sure that under normal conditions that an Android device should never power the USB port. Source of speculation. If it is indeed powering the USB, then you've either got a really wonky firmware installed, or some sort of hardware issue. I'd try to make sure that it's sending power out before going further (especially if you can't charge it, the battery will be dead soon). After this test, I'd keep the battery out for a while, just to be sure it's not going to short anything.
One thing I've noticed in my tinkering is that taking a device apart, then putting it back together again can mysteriously fix problems (although 75% of the time the fix is temporary). If you suspect water damage, opening it up and letting it air out might help. I want to say there are certain cleaners that are great for cleaning up any water spots that might be shorting things out, but I've never had to try myself.
That's all I can think of right off. Good luck.

Yeah, I'm working on taking it apart right now. With my limited experience on electronics, I would be willing to bet it's a capacitor that's gone bad somewhere. That wouldn't be a problem on a desktop since I could just solder a new one in, but I don't think I have the skill to do something in such a small scale, not to mention I don't think you can even buy them that small.
The same thing happened to me, and I had to send it in for repair. Luckily, I was still in warranty. Also, are you sure it's not the charger cord?

I've tried multiple cables, and I'm unfortunately out of warranty.
Upon disassembling and cleaning with rubbing alcohol, it seemed to be working properly, with the exception of computer connection. However, I plugged it into a DC car charger (leaving the charger itself unplugged from an outlet), and the light came on again (which is what I was talking about when I said it was sending power out), and now it is acting weird again. I guess I'll take it apart and clean it again...

See! Told you taking it apart and putting it back together again works... temporarily. :silly:
You're right, that does sound like power going out. Which would be super cool for powering, say, a micro USB laser pointer, but it's not so great when it should be charging. Can you double check with another device that the charger doesn't light up normally? I know my wife's laptop charger has a LED that stays on for a long time after it's been unplugged from the wall, sipping off of power left in the charger. It could be something similar with your charger.
Just a though... if power is only suppose to go into the device, then wouldn't it be reasonable to assume to that there would be a diode forcing power to only go one way? Or does it need to cycle power back to the charger? IDK, but it might be worth looking to see if something looks missing.
I read somewhere that if the battery voltage gets too low i.e. battery is totally flat, a current will flow from the device to the charger so this may be what's going on here. I didn't really understand the post as I was just whizzing through the thread, but i think the solution was to charge the device for many hours until the battery voltage was high enough for normal charging to occur. I'll try and locate the post, but it might take a while

@iJimaniac if all of these suggestions dont work, there is the possibility to just buy another battery and a battery charger and keep switching out the batteries when they die
Maybe @henk5066 would know something about this?
From what it sounds like, your power circuit is fried and is not directing power correctly this means that you're probably going to have to replace the mainboard. however don't worry. you can get one from a player with a broken screen on ebay for about 10 $. I can p.m. you some links to products on eBay with main board working and not screen and I can post a video on YouTube that shows you how to replace the board. it's actually rather quite easy. I don't get why most people don't do that and instead buy a new one. let me know if that helps

Wow, I didn't realize a broken player is so cheap. I'll look into it, and instructions won't be needed; I've already fully dissasembled my device many times in the past, just for kicks.
Edit: could you send me those links? I'm having a hard time finding very many under $25, which is still a good price I suppose.
the broken player it's self is cheap (0.99$ if your lowest bidder and win) it is shipping that makes up for most of the cost. Just make sure you get one that says powers on, that is the main indicator that the main board is still good.
EDIT: I just looked on ebay, aparantly the person i bought my new board is out of the 4.0 player. and it looks like there is however one with a 9.99$ bid. you could raise it and get the player but that is the cheapest you will get. i will pm you a link to it.
I had the same problem
I had the same problem, what i did was, instead of charging it with the original charger, i charged it with my nexus 10 charger in download mode all through the night, and the next day it would have about 80 percent charge and it was in the system, but it drained quick when i would unplugged it, so i repeat the same procedure over several days until get to 100% and scince then i have had no problems with my SGP, hopefully i helped you

On the subject of odd charging behavieor, has anyone noticed that when plugged in running cyanogenmod overclocked to 1200mhz, the micro usb port area on the player gets rather hot?

S3 (Int) won't charge

Hi XDA,
My Galaxy S3 stopped charging properly a couple of days ago. In a matter of hours it froze and charged a bit slower, then it wouldn't charge anymore. When the phone is off and I plug in the charger, the animation starts for about 1 - 2 seconds, and then the screen goes black. If it's on, nothing happens when i plug the charger in and out.
I've owned the phone for a year, and I rooted about 3 weeks ago, and installed CM10.1 (Nightly). It worked fine until this problem.
I've troubleshooted a bit on my own, and what I've found out is that, it can't be the battery that's the problem, because I've tried three different ones, and the problem stays the same. It can't be the USB port on the phone, since I can get it to work in Download mode (ODIN mode). I've also tried CM9 and flashing back to stock android. I've also tried charging it from the wall and the computer, and used different cables. Nothing has done any better.
I'm guessing it's software related, I just can't figure out how to fix it.
Thanks in advance,
Zhibbhi
the charging port of the phone might be faulty.

By charging port I would suggest the charging circuit inside the phone is faulty, as it sounds like you've eliminated all the other possibilities. Return the phone to fully stock for warranty repair.
So even if I can access the phone through ODIN, the charging circuit can be faulty?
I just thought it was a strange coincident that it went faulty a just a couple of weeks after I installed CM10.1

Odin has nothing to do with the charging circuit .
Solutions .
One the battery try another
Two the charger try another >> charge phone from PC usb .
Three the cable try another
Four the USB port on the phone >>> clean
Five the onboard charging circuit >>> needs a service centre .
Six and highly unlikely a firmware problem wipe phone flash stock rom .

Ok, thanks a ton guys! I'm going to set the phone back to stock, and send it in for warranty repair as I've tried everything else.

In the future, avoid using S3's stock charging cable. I changed mine to one I bought off eBay and had no probs since then. I had several frequent problems like slow charging/no charging etc.

Best avoid using the phone to charge the battery at all, that way you don't stress the phone components with wake lock and heat. Buy a £6 desk charger and spare battery, replacing these is much cheaper than the phone motherboard.
Solved
I have an S3 and lately it has taken longer to charge and it was charging to less percentage. I tried 2 different chargers and 3 different cables with the same outcome. I was thinking about one of the threads I had read and they mentioned going to the cell store and it charged for them. I've read about it being the charge circuit on the main board and various other problems and solutions that didn't work. I went to Staples today and purchased a SCOSCHE reVOLT line h1 2.1 amp quick charge and in less than an hour I charged from 63% to the 100% I haven't seen in quite a while. The Samsung OEM charger it seems (as well as the other one I tried) had lost some of it's get up and go. It is working fine now and with this charger it doesn't take long at all to reach full charge. I've put a lot of time into customizing this phone after root and would have been VERY disappointed if I had to start over with a new one. I'd be willing to bet at least 90% of the charging problems people are posting about are caused by the charger deteriorating over time.

Poco F1 is dead

Hi everyone, I got a poco f1 from a friend. He used it quite normally. The cellphone was off for about a month - it didn't work. After a month I tried to start it however unsuccessfully, poco f1 is dead, I tried to charge it but it can't. What could be a malfunction? Help if you know and thank you very much
First, try using a different charging cable and brick. If it doesn't charge, Check if it can be read using a computer or laptop. If it still doesn't work, then the issue may be the charging port. If that's the case, if you are still covered by warranty, then go to xiaomi store. If not covered, go to a proper technician.
Btw if the device can be read on a computer, then it may just be a boot issue. Just flash again.
Does the white charging led light up when it's on charge?
If not, have you tried leaving it on charge for an extended period?
I've had difficulties with phones in the past after batteries have fullly discharged - eg the Moto G5 had some battery protection "feature" that stopped it starting up if it thought the battery was fully discharged - it was a bit over sensitive so would sometimes assume the phone was fully discharged when it wasn't
Try leaving it on charge for 24 hours or so then holding down the power button for for at least 20 seconds with it still on charge
If you have no luck and the warranty is out, get to a repair shop (or disconnect and reconnect the battery if you're confident to open it up - for a while I was getting sporadic shutdowns with my F1, following which it wouldn't take any charge, the battery light staying off when plugged in. This was all fixed by tightening the screws securing the black motherboard plate, the cover which retains all the connectors - not sure why but it seemed something, I suspect the antenna connection, had come loose. Since doing this about 5 months ago I've had no further shutdowns and my phone is usable again, having been completely unreliable before)
One trick that worked on some old Nokia phones was to charge it plugged to a computer instead of plugged to a charger - but as said elsewhere, if the battery is completely dead, YMMV.
Also, try to press and hold the power button and while doing that, plug the phone to the charger and then release the power button.

I guess your battery is dead
I have same issue, however I think my one is a motherboard charging IC issue. Does anyone know a way I can get it cheap from India, as I’m in the UK. India have it for around 9999 rupees which is about £10(+international shipping). I’ve ordered a charging port replacement from AliExpress to see if that solves the problem. However I don’t think that will work. No idea how my motherboard got damaged in the first place. I replaced a cracked screen myself and the phone was working fine for a few weeks, then it stopped charging all of a sudden. My PC also detects it/can access files doesn’t charge it. A new battery powered powered on the phone but again didn’t charge. Tried different adapters and cables too. Any experts out there know whether this is a motherboard issue or just a charging port issue?
If the phone is OFF for a month, then it is probable that the battery has gone down to a point that the BMS has shut it down. The BMS won't allow you to charge the battery because, in its own assessment, the battery is dead. Best way to test this case is to have another Pocophone with a good battery (or just a new battery altogether), detach the cable from that and test on yours. This may or may not work but this is one of the easiest to test and a new battery is easy to acquire.

If the phone is OFF for a month, then it is probable that the battery has gone down to a point that the BMS has shut it down. The BMS won't allow you to charge the battery because, in its own assessment, the battery is dead. Best way to test this case is to have another Pocophone with a good battery (or just a new battery altogether), detach the cable from that and test on yours. This may or may not work but this is one of the easiest to test and a new battery is easy to acquire.

Before you do that, just try leaving it in charge for 24hrs as suggested above, though it does look rather as if the OP has nicked off so won't be using any of these sage words!

P30 Lite Charging Problem

Hello,
firstly i m sorry if this is the wrong section, i m new here.
Now to the issue. I have a Huawei P30 Lite with broken LCD. I replaced the LCD with an original Huawei service pack which included LCD, Frame, Earpiece, Battery, buttons etc. Basically it included everything except motherboard, charging board and coaxial cable. The problem is that after the replacement the phone is not charging. At first it was showing that it was charging without any success (% going down instead of up). After the phone battery drained, there is no charging at all.
Doing a full hardware check i noticed that there was indication of water damage on the charging port. I replaced the whole charging board. Still same result.
Reinstalled the old LCD pack (battery had some juice in it still for testing) with the same results. When the phone is turned on, i get a charging signal and the LED indicator but without actual charging. When phone is turned off i dont even get the LED indication of charging.
Steps i already took to save time:
Changed the charger. Used up to 2.1A charger with fast charge cable aswell.
Changed the charging board.
Tried both new and old battery, internal connectors etc
Cleaned the whole motherboard with alcohol to get rid of any debris even though there is nothing visible
The phone was working normally before the lcd replacement.
The phone is working perfectly with the remaining battery and was working perfectly until the new battery drained aswell. Only problem is the charging.
Cannot perform cache cleaning since battery is dead
Software upgrades, reinstalling etc will certainly not be of any help since the phone is not charging when turned off.
I am trying to avoid costly and time consuming repairs since the only fault i can assume anymore is human error which most likely i would have noticed during the repair. I cant accept that the main board died suddenly after a simple 2 part replacement and the only thing affected was the one that had water indication on it which didnt affect it so far.
I am looking for any kind of ideas since i am totally out of them.
thank you for listening.
Hey, i know its 1 year later but i wanted to ask you about this. I had the exact same problem as you with a p30 lite aswell. Did you find out where was the problem? Could you fix it? Thanks
