At night I was left with 90% battery . But at morning I found my phone on floor dead. I tried to open it , but it shows empty battery. Then I tried charging then MI logo came and again showed empty battery and phone is not charging. There is no external damage to the phone as I used a rugged cover. What can I do now? I tried force reboot , fastboot etc. But no response , just MI logo and empty battery while charging.
You need to Rma the phone as internal circuits are probably damaged
As there is no proof of external damage or proof you dropped your phone there is a big chance they will give you a new one

Sadly I have no warranty. It was not connected to charger. How the circuits probably damaged ? Any other idea?

Why do you not have warranty?
Circuits may not be damaged. Most probably, the fall might have loosened some of the connections. So if you really have no warranty, you need to open up the phone, check the connectors, especially the battery connector and clean and refit them. Check some videos on opening up the phone and use proper tools. Don't force anything.

got this tonight,
let the battery get down to ~10%
plug it into the OEM USB wall charge and cable, "battery disconnected"
plugged it into my PC with standard micro USB cable " battery disconnected"
pulled out the battery, and now it seems to be taking a charge, is this something others have seen? is a brand new phone on the first battery charge
Charge over four hours to 100%.
Still a problem return it to the seller .

If it says 'battery disconnected' it probably means that your battery is not touching the pins properly.
I had the same problem and i put a small wad of folded paper behind the battery and then slid it in its place. The battery is now pushed firmly against the pins and voila! the connection is proper and no more 'battery disconnected' !
Hope this solves the prob, if it hasn't already been solved
Same situation here, used some contact spray and problem is soled so far.

Replace USB board/port. Search for KeithRoss39's guide (it isn't stickied, do a search for 'replace USB charger board' or similar). This is quick/cheap (US$10-$15)/easy to do, Keith's thread has all the info you need.
Dont worry
Hey, This is not a big issue. If you get a message as battery disconnected, then it probably means that you have to turn off your phone and take off your batter and put it back. Simple.
If you see same result again, then just simply buy a new batter. I have faced with this issue but now is ok after just taking off and putting it back.
All the best

Took a Q-tip dipped in 91% alcohol and rubbed it to the contacts on both the battery and the phone. No more error. Battery appears to be charging, no problem.

Thanks alot
none of the above worked. looked closely at the contacts and realized there was a thin plastic strip on top of the contacts to protect them. a bit hard to remove the plastic strip, but then the battery was no longer "disconnected" of course

try not to force much the contacts of the usb port or you will be without MTP connection (as happened to me, you can only charge the phone)
So, to start this off my rezound fell into a pool with me. Rushed and did the usual steps for drying it out and all that. The battery was the only thing that took water damage according to the sensor. So I bought a new one and it won't charge the battery. The one time I got the phone on it read 0% charged after sitting for 6 hours. Now it's either blinking orange or staying orange for around 5 seconds. Is there anything I can do?

Sounds like your phone is damaged, the old battery was probably fine, the water indicator is there to let Verizon know the phone had water damage when people try to warranty them...
I'd throw it in a bag of rice a little longer, see if there's any more moisture stuck in it, otherwise it's time for a new phone...
I had a similar situation, minus the water, but you might try pulling the battery out and charging it manually with a power supply set to supply 5 V and current limited to 1 A. Let it charge like that for 20 min and try putting it in the phone again. If it still will not work, then it could be that the leads on the phone that connect to the battery are corroded and need to be cleaned.

How would I go about doing this?

I take that to mean you don't have access to a variable voltage power supply. Not a problem, but it would help if you at least have access to a voltmeter or multimeter. You would need to plug in your charger with cable and test each of the leads to see which two have 5 V across them. Then attach wires to both and the other end of each wire to the positive and negative leads on the battery itself. I would use a different cable (not micro-usb) so that the leads are larger and easier to access. If you cannot do this, then you could use a stand-alone battery charger like this:
http://www.verizonwireless.com/b2c/...peId=12852&accessoryId=48042&initialPhoneId=0
But that would require you to buy one, which may be a waste if the phone is actually the problem. But if you do buy it and it turns out the phone is the problem, you could keep the receipt and get a refund.
As far as clean the leads on the phone, you could try mixing baking soda and water (little water) into a thick paste and scrubbing with a tooth brush. The paste will need to sit on the metal leads for some time (30 mins to 2 hours depending). Then use isopropyl alcohol (rubbing alcohol) on tissue to clean any remaining garbage/residue. Then you will need to let it dry again, ideally in a sealed container with silica or rice. I would probably leave it in there for at least 24 hours.
If both of these don't fix the problem, then you probably have either shorted some internal circuitry or have some other corrosion inside the phone somewhere.
Well I really can't try that suggestion broke college student and all. Thanks though.
You can get this external charger cheap. I have it, works fine:

Hello all!
I recently purchased a used Droid Razr Maxx from a co-worker. The lcd screen was cracked so I replaced it. I took apart the phone completely and reassembled it with the new screen in place. The phone turns on just fine, the Motorola icon shows up and it gets to the charging battery icon with 5%, but after a few hours of letting it charge, it stays at 5% and wont turn on. Keep in mind, the phone has been charging for two hours from the time this post was made.
My question is, did I somehow damage the battery when operating internally? I can replace the battery if needed.
Another question. If I damaged the motherboard, would the phone turn on at all?
I am kind of wondering if there is a certain thing I needed to do before plugging it in.
To answer any questions that might be asked: The battery was completely dead when I did repair the screen. The charger is a wall usb charger, not plugged into my computer. I did place all the components inside the phone, to the best of my knowledge. I have had experiences when it comes to internal repair.
check for how long this 5% charge remain. it usually happen due to problematic battery guage

Morning now. The battery is still at 5%. The phone shuts off soon as the charger is not connected. Does not seem to hold a charge. Think I should buy a new one?

It could be a faulty charger.
Normally, If the battery is poor, it won't hold charge but it won't stick to a particular percentage. It will only discharge sooner. But given the fact you got the phone dead, it might as well be the battery.
Worst scenario, you damaged the charging port.
I'd begin with using a different charger, if that doesn't work, try another battery.

I have used other chargers and they all work for my other phones, just not this one. I am hoping it's a dead battery and not something to do with the motherboard. My friend wont let me dismantle his phone to see if it's the batter, lol.
Just the clarify, the phone doesn't boot up completely, only to the charging screen. The battery icon with 5% shown. When I unplug the phone from the charging screen, it just dies. Will not even boot up to the phone animation.
I purchased a battery replacement off of Ebay. It'll arrive in a few days. Let's hope this works!
Still could be the charger. Did you check voltage and amp specs? 850amps 5.1v
This phone can be picky. First razr I got had broken screen, repaired it and found myself in the same situation.
Connecting to a laptop would not charge it. Only stock charger. IPhone charger or chargers designed for iphones will not work.
Edit: When replacing battery, position is critical. If battery terminals are a little bit displaced it will not turn on.
Displacement can be minimal or imperceptible but will cause troubles. If possible don't place cover before checking that it turns on. (please avoid touching circuits or battery terminals or will get worse).

That was exactly the problem....
I got the new battery, but not 24 hours later, I was realigning the cables inside it (like the front facing and rear cameras, along with the WiFi antenna) I slightly moved the replaced battery and the cable to the battery to the motherboard tore itself. After a long face-palm moment, I got the old battery back in place and realigned it very carefully. It turns out it still works, but I am out a new battery.
Apart from the battery, I need to find out why the front speaker won't work. Either the speaker is damaged or something needs to be in place correctly, besides the cable. Also need to get some adhesive gel to bond the screen and case together.
Damn I really had forgotten about that speaker. The fact is it tends to break. It has very fine copper wire winding that can break when you remove it the wrong way.
Having no experience I pulled not knowing that speaker is glued to motherboard. At that time I didn't knew it and thought that little bar left was part of the motherboard.
Since you disassembled almost everything, that must be the reason it is failing. If it is not that, it is badly plugged but I really doubt it.
Alas Never fixed it, so i can't tell correct process to reassemble or disassemble that speaker. Instead I searched for apps that would activate loud speaker automatically during calls.
Would have been nice to fix it but I got the opportunity to acquire a RAZR maxx so never touched and sold instead.
Removing that glue might involve using a hot air gun. So that you don't damage motherboard removing by force. (But again too much heat could Fry motherboard)
Maybe someone could share it's experience?
About that screen, Remember to have read about a 3m adhesive spray in some thread.
Also some one just passed hot air that melted original glue but it would be better not to play with heat over a battery.

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.

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!

yep mine also. i was playing genshin impact and suddenly it freeze and off. service center said it was dead motherboards.
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.

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.
