Question Phone wont charge past 59 percent. - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

2 weeks ago i tried something stupid. I made a USB charger for my scooter from an old navigation charge brick for te car. without thinking i plugged in my phone and *poof* off. I thought it was strange because it has a limit of 5v and a fuse of 2a, so i thought it was within the safe area. I started my phone again, but when i wanted to charge it, it was really slow. (200 ~ 400ma). So i thought i fried my USB port, and ordered a new one. I replaced it but the charging problem still appeared. So i thought maybe its the battery, same story. ordered a new one but the problem was still there.
So i tried to re calibrate the battery by discharging it to 0 and let it fully charge while off. When the phone went of it didn't detect any charging and wouldn't boot. When i measured the voltage of the battery it discharged to 2.7V, i externally charged it to 3.2V and my phone booted again.
a friend advised me to return to the stock miui version and firmware version from when it came out of the box. So i did butt it didn't help me solve the problem. My phone think he is fast charging but the current is around 200 to 400ma and above 50 percent its at 50 to 120ma.
The last few days i am trying to find the schematics of the phone and especially the power circuit, i can find a few pictures, and there are a few sites that offer the schematics. But i cant seem to find out to download them from there.
Is there anyone who knows where i could find the right schamtics, or point me in a direction where the problem/defect is coming from?

Use original charger and cable?

Yes i did actually tried 5 different charges and 5 cables, a car charger, powerbank. I found the schematics yesterday and found out where the IC is located what may cause this problem. But i can only order it in china so i have to wait 2 3 weeks.

Broken USB/charging port?

I'm not sure if this is the right place to ask this, please excuse my ignorant.
I have an EVO that won't charge. I've read a lot from Google search results that this is a common problem among many users. However, the port seems to be working, because my computer will recognize the phone and storage when I plug it in. The charge led will come on, and the indicator on the phone will say that it's charging, but the phone is actually only discharging while plugged in. Eventually the led will turn itself off, and the phone stops telling me that it's charging when the battery is down to its last drop.
I hope that someone with similar problem can help me with fixing this, or if anyone cause tell me if it's possible to fix? I want to send it in to HTC since I think the phone is under warranty, even if I don't have the protection plan from Sprint? The problem is the touch glass is cracks, and I don't know if they'll fix the USB port without saying that I broke it and won't cover that under the warranty. I want to buy a new screen and replace the broken one, but if I open up the phone it would void the warranty as well...
So I'm stuck with a discharging phone, cracked screen, and having to carry around 3 separate batteries everyday, and I have no idea what step I need to take.
Please help?
Have you tried plugging it into another charger? It may just be the charger that is screwed up. If this behavior pattern is consistent across multiple chargers then you may want to talk to Sprint to see what options you have.

Doubt it's the charger as it was stated that the computer connection works - should get a bit of a charge from that. I agree that a Sprint visit is due.
Just went through this myself! Would plug my phone in before bed and wake up with the phone at 2% or so. Thought it was the battery- so i took my battery to have the sprint store check it, they did say it was bad. So i bought 2 batteries off ebay.
I got the batteries and still had the issue. So then I took my phone to the sprint store and had them check the micro-usb port. They said it was fine and they cleaned it out cause dirt/dust was in it. Still had the problem..
So I bought a new micro-usb cable of monoprice (still using the same wall charger) , and that solved the issue! Had a bad cable. Now my phone charges super quickly in matter of 4hrs.
It could still be the charger. The USB cable sends data and power through different pins. So a bad cable could still transfer data while not pushing a charge.

It's gotta be the port happen to mine and I was able to get it fix as long as the port was still attached to the motherboard, if its not attached then have to go thru the insurance.
EVO with Identity Crisis
I was able to connect to my computer and send data just fine with the old (broken) usb cable.
I've tried three different cable and a car charger, same result; they all say the phone is charging but it only gets discharged. USB/storage connection works. Last time the Sprint store said the battery is faulty, but I have 3 different ones and neither will get charged with the phone plugged in, an external charger will work.

Definitely sounds like a port issue then. If you return to Sprint and review what you've done, as well as the result of your previous trip, then they should be able to take care of you. If they try to tell you it's the battery again just stand your ground. Good luck.
I had a similar issue. I tried everything. It wasn't until I found my HTC cable that it started charging again. I work in IT and tried cables from everything I could get my hands on (blackberries, external drives etc. ) The cable that came with my phone was the only thing that worked.

If you replaced the port yourself, I would love to know how to do it!
Took the phone back to Sprint and they said there's nothing they can do. I don't have the protection plan so I couldn't even pay the $100 to get it replaced (although I probably wouldn't as I can upgrade my contract and get a new phone soon). They also told me that HTC wouldn't cover it under their warranty because the screen is cracked and they will blame that on me for misused. I tried to check the warranty policy on HTC, but the page is not even available. Does anyone have experience dealing with HTC? I bought a replacement screen, I'd like to replace the screen but don't want to open up the phone if there's a chance HTC will fix the USB port...
HTC EVO 4G Won't - Stopped Charging Battery Issue
Hey Guys,
Two nights ago I woke up to an EVO that was plugged in with a Cellet
extractable charging cord, as it is just about every night. But, the phone was
still showing that it was charging the battery, animation with lighting bolt,
at only 50% charged after about 6.5 hours of charging. Hmmm....
The latter after trying to charge in the coffee shop first with Cellet chord in the
wall then a portable 3500mah solar portable charger; the phone not seeming to
charge at or past 50% charged.
My EVO is rooted but still with the stock ROM and the gingerbread 2.3.3 OTA
update. The battery is a Seido 1750mah and SetCPU is at 245 - 998mhz. The
phone has only been rooted for a few weeks, but I don't see where rooting
would interfere with battery charging.
I've pulled the battery out, several times to no avail. Switched back to the
stock battery, same results. However, if the battery is less than 50% full
the phone will charge the battery to 25% or 50%, weird. If the battery is
at 75% or more full, the phone will top off the charge to a green LED at 100%,
sometimes. Sometimes it won't fully charge the battery. Weird.
I read different posts regarding poor USB chords so I pulled out the stock
micro USB to USB, a charge only chord I figured, and am trying to top
off the Seido battery, which it seems to be doing as it's now full green but
still charging as the animation shows the bolt in the battery and the LED
is still orange.
If put the batteries in the Seido wall charger, the thing the size of a deck
of cards, both batteries fully charge.
I also use Screen Off by Iwashi Soft. That app has worked pretty well with just
a little funkiness now and then. However, while plugged in, I hit the power
button, instead of the home button to turn on the home screen. The phone
wouldn't open to any screen nor would turn on or off. So I ended up
yanking the battery to turn it off then reinstalled battery and turned phone back
on. I don't know if that had any effect on the charging issue, but I took
the icon off the homescreen and am using the power button only, for now.
I don't think both batteries are faulty at the same time at this point. I
don't know if the screen off app caused some wake issue that interferes with
charging the battery.
I do know that when plugging in the phone to charge there's a bit of clunkiness
initially as the phone locks for a second before allowing use for screen or app
and that's always been the case since the gb update. Also, the LED doesn't
always turn green from amber when fully charged with the screen off until
you reboot or use the phone in some way while still plugged in. So there is
some kind of wake issue in the stock ROM. But the latter has never stopped
the battery from charging.
I do know that Plume, the twitter app, started acting clunky with not updating
in the background unless I opened the app at least once after a reboot. But
I don't know if the latter is a wake issue.
Battery still seems normal. Heavy normal use, lots of SMS, tweets, Pulse reading,
Dolphin browsing, I'll kill 50% or more of the battery in 4+ hours. Otherwise, the
phone mostly in standby with periodic email and twitter reads, the battery lasts
all day or more than 24 hours. But the latter rarely happens anymore because I'm
a user.
The battery just went full charge with the stock charging cable just now.
This morning, I woke up with a dead phone, auto shutoff even though it was
plugged in which I did after solitaire and before going to sleep; as a charging
test.
I don't know if it's the phone or the Cellet retractable cord or both that's
stopping the battery from fully charging normally and consistently. I'll need
to get another data-charge combo chord and do more testing; and a new ROM.
Any ideas anybody?
try a new rom and also try using the stock charger and usb cable. Check inside your usb port on your phone for dust as well. Also go into recovery and wipe your battery stats. In the wipe menu for amonRa and under advanced (maybe here, i dont use cwm on my phone) in clockworkmod. also wipe your dalvik-cache just to clear any issues you may have, restart and give it a test. good luck
I just bought a phone with a broken charger port. Broke clean off the board, so my next step is to try to get liquid solder and stick it to the board. Did you take ur phone apart to see if the port is lose?
So I used the stock USB charging chord. Sure enough, it charged the phone.
Then I tried the portable charger at the coffee shop, worked. So the Cellet retractable
chord obviously had a short or something damaged/shorted for the charging part of
the cable after a year + of use and abuse.
What I don't understand, and haven't researched, is why there are charge only
chords; the stock USB HTC chord charges the phone, but the PC won't recognize
the phone's Micro SD card or the phone as an external drive. I presume the duo use
chords have a data path as well as a charging path. And yes, I know to switch the
phone from charge only to disk drive. The Cellet chord would provide the PC with
recognition for the phone's drive.
Considering the latter, what I'm not sure of, and haven't researched, is why when
the phone stopped charging, the chord eventually stopped charging, the phone
status still showed it as charging; the amber LED light on and the battery icon
in charging animation with white bolt showing? I presume that the charging path
still triggered the charging status, except once when I turned the screen back
on the battery icon was not animated and the white bolt not showing so I unplugged
the chord then plugged it back in where the battery icon animation continued.
Fortunately, or not, this forum returned 600+ results for 'battery not charging' and after
sifting through a few, the charging chord was mentioned which prevented a Sprint trip
and me contacting Seido; thankfully.
So I think manufacturers and ROM/kernel developers should visit this issue as a chord
that actually is not charging, or charging at an absurdly low rate, should trigger some alert
and not show a battery icon animation that appears to be charging normally.

charge time 10 hour

if i charge my arc s from ac or usb it will need 10 hours to recharge, if i use a little when is chargin it start to lower battery, get really a little amout of energy when charging its not different if from usb or ac, do is this a thecnical problem i have to ask repair center or can be software side fixed?
You could try a different battery, it might have come to the end of it's life and just needs replacing. How long have you had the phone and / or battery?
its less than 6 month, battery monitor widget say is good health

There shouldn't be a problem with it then.
I know it means resetting everything, but you could try flashing the ftf again. It most likely won't fix it, but Sony would ask you to try a reset using pc companion before you send it back anyway.
I have clockworkmod installed but no unlocked bootloader, if i do a reset than can i restore everything from backup?

Yeah, you can. Though you'll have to root again and install CWM, it wipes everything with a fresh install.
10 hrs from USB is acceptable..but not via AC...something is wrong dude..did you try with different charger? try samsung charger..note and S2 and S3 charger allows more current hence charges the phone very quickly.
ok ive made a fresh install from pc companion repair service, updated to ics, now is really worse, i put all the night the phone charging, it charged from 25% to 45% after 9 hours, if i use the phone just a little when is chargin it dont charge at all but get low battery. im the only one having this issue? i assume i will have to send it to sony support but i would like to understand what could is causing this, THIS IS FROM ONE MONTH, BEFORE IS ALWAYS CHARGED FAST, AND FASTER FROM AC, ive always charged the phone from usb via pc, occasionally charged by ac from cigar socket inside my car, this was a cheap sub socket i bought for 5 euro, could it be this?
now i cant use the phone at all, if i put it on cant charge because battery is used more than how much is recharged, i have to keep it off and wait, hope that reverting to gb will make the chargin time a bit faster, i want to keep it still awhile before send it to sony

Got one last idea for you. Try a different usb cable to charge it. The cable might just have worn out.
It shouldn't be the car charger, as long as it had the same charging rate as USB charging or AC charging.
nope, already tried a different cable, i cant understand whats wrong with this phone, ive recharged it 20% yesterday, ive put it on airplane mode before sleeping and today at morning after 9 hour it is 5% battery
and sony support in italy is really bad, ive to bring the phone to a collect center that will ship it to the support center ill have to wait 2 weeks to have it back
i just discovered that charge time from ac is 7 hour, from pc usb take more than 20, if i leave the phone to the usb with the pc off the phone totatlly drain the battery i dont know how

[HELP] Phone won't charge.

First it stopped fast charging. I then later it would only charge sometimes and then accidentally dropped it and now it wont charge at all. I don't know what to do. I tried another note 4 charger and it won't charge on that either. I just got the phone last Feb and it broke already? Is there anything to try before I take it somewhere to be fixed?
Phone won't charge on a note 4 fast charger
Tried 2 note 4 fast chargers.
When the phone is off it sits on the screen with the battery and the thunderbolt but never charges or shows a charge %.
Please help. The phone is in a pelican case. It doesn't look damaged from the outside but I don't know about the inside.
Edit: As soon as I posted this I tried again and it charged with fast charger. I don't understand what is going on.
Maybe the charging port is loose...You can try using wireless charging thought that will require a new back cover/ insert and a qi charger
Warranty. Go to AT&T Device Service Center
The battery could be defective as well. Try another battery or take it to ATT and tell them its not charging, they should have an extra battery to test with as well.
When you tried the other chargers, did you use their cable or the power block with your cable. My son had a similar issue with his Note 2 and did what you did but used his cable. Turns out the cable had a short in it. Replaced the cable and it charges fine ever since.

vooc charger not charging

my find 7 vooc charger not charging any phone, few hour ago its charging my phone until 50% and its not charging again. any advice please?
Have you tried using other chargers or a USB to computer connection? It's possible that your VOOC charger simply kicked the bucket.
battery connection
i also faced frequent issue with my VOCC charging, sometimes its fast sometimes not, i knew that once above 80-85%, VOCC will stop.. but sometimes i cant get VOCC even at less 10% juice left.
but i found that removing the battery and reattaching it fixes the issue.. due to this my Carbon Back Case is damaged lol... too frequent.

I had the same problem. Oppo find 7S bought in china, used in Italy, after 1 year use the oppo VOOC charger stopped working :crying:, it doesn't charge any phone, the model of the charger is the old one, where you can't change the cable.
To solve the problem i bought the new one, and now i don't have any issue, hope this still work the next year. Greetings!
Ps.: Also my girfriend had the same problem with the VOOC charger, now she uses another charger too.
Same problem here, but is not the VOOC charger, but the battery itself....
I say it, because i have another batterie e and the VOOC charges normally.....
I presume some how, the original battery has reach a ending cycle of life....
Somehow i discovery this to help VOOC kicks in:
Use times to times another different charger, then VOOC. It seems sometimes to help.!

Not only has my phone shut down itself over night and showed 0% battery the next morning, but now also my vaac charger starts to charge for about 5 secs and then stops. Must be the battery and I'll contact Oppostyle now..
this is how my problem was solved

I had 2 issues:
1. VOOC not charging fast, but was charging, but extremely slowly. Including using other chargers
2. Phone not recognised when connected to computer via USB.
I took it in to the oppo service center in bangalore last month. THey fixed the issue by (what they claim) replacing the usb port and circuit within the phone . This took only 1 day. They also downgraded the software to the coloros 1.2 . They were very uncommunicative and had no proper process in place, including giving a handwritten receipt and bill!!!
But the total cost was inr830 or $12 so it was cheap and quick and it seems to have fixed the issue.

Samsung Galaxy Tab 3 8.0 (SM-T311) not charging: troubleshooting help needed

Hi there,
I have received this Galaxy Tab 3 (SM-T311) and it does not turn on nor charge.
I have tried the various suggested button presses, I have tried unplugging the battery for a while. Now I am leaving it to charge but this was already tested by the previous owner with no success.
I would like to find out if charger circuit, battery or motherboard need replacement.
I have tested with a multimeter that battery leads show 3.7V - with charger plugged or not. With battery removed the leads show a value of 0.4V.
Can somebody help to figure out whether it is a battery problem, a charger circuit problem or a motherboard problem? I think it might be one of the first two since battery charge should not be so low.
Thanks
By the way, I have already been through this video: https://www.youtube.com/watch?v=m2VJ_VRIRSI
Which comes from this blog post: http://www.bigpicturebigsound.com/Samsung-Galaxy-Tab-3-Won-t-Charge-or-Turn-On---How-to-Fix.shtml
I am not using the original charger and cable but a 2A one, sorry but I do not believe that the original USB cable and PSU would be any different it's like with HDMI, it's a standard. The only thing that could change is the power intensity which is 2A as per original.

Sorry I can't help, except to say it sounds just like my problem. I'd been using mine mainly as a clock/alarm clock using a great alarm app. The battery was good enough to last about 15 or more hours with a clock display on, but then I left for a 2 week vacation, and decided to turn the tablet off rather than leave it on a charger. Came back and it was dead.
I also did all sorts of button presses, used various chargers and cables (I have the original charger, which works for other devices, but didn't help). I disconnected the battery for several hours. Tried charging off a computer USB-2 port. etc, etc. Still, "It's dead, Jim".
I suspect it's the battery, which is pretty old now, and has been left on the charger a lot lately, though not 24 hours a day. Lithium batteries don't like to go totally dead, but I guess that's what happened. If the tablet were still useful to me, I'd try a cheap one from Amazon, not really expecting it to last a long time, but useful to see if it works without losing too much.
I've seen one repair tech who fixed a similar problem by disconnecting the battery and connecting it to a power supply briefly to give the battery enough of a charge to get the phone to start charging it normally. Obviously, this is something that mere mortals would not be able to do.
