Hello Everybody
My phone was working fine until last night when the battery completely drained while i was playing a game and it turned of. After that i plugged it in and went to sleep. i woke up this morning and tried to turn it on and nothing happened. I took the battery out put it back in and it started charging. i left it there for 20 minutes and when i came back the phone is completely dead. no response. won't charge, wont turn on, wont vibrate. nothing
so if you could help me out with the problem that would be great. thank you.
The battery may have shorted itself. You can purchase a new one for ~$10 on Amazon.

Thanks for your help. I just got done testing my battery in a friends s4. Its not the battery. His battery doesn't turn on my phone and my battery is fine in his phone. Its my phone that has a problem. Any other suggestions you might have will be really helpful. Once again thanks.
Well, if a charged battery isn't making it turn on at all, then the logic board is probably malfunctioning/hard-bricked. The only solution to that is to replace the logic board. Your best option, if you are in warranty, is to contact customer support and have them send you a warranty replacement. If not, the best option is to purchase an S4 with a broken screen and swap out the logic boards (better be comfortable prying open your device).
Thanks for the help.

Hello,
my GSII does not take any voltage from any source (USB port or the charger) therefore can not charge it.
I have already bought a genuine replacement battery from my Samsung and already bought a USB board (thought it was the plug on the GSII) and made the replacement. When the battery came, it still had about 50%, the phone booted up just fine, never was able to charge it, after that i always get the temperature icon, even the temperature is not very high. The same battery also did not charge on a GSII friends phone.
This is a very strange symptom, any help or ideas would came in hand.
Thanks,

Could be a hardware issue.
If you are still on warranty, go to the store/service center and ask for a warranty replacement of the battery and/or the phone.
Good luck !

Thanks for the answer, i'm out of luck, it was an eBay buy.
Just to add more info, i have a mains charger 5V, 1A. I've used it for months, i know that the GSII takes 0.7A but it is capped (read this on this forum), so i used this one for convenience.
I don't know if it has something to do with this.

Hey guys! I'm needing some advice/tips.
I've had my g tablet for about a year and lately it really has started acting up. The power reading on the tablet was either like 100% or dying. Last week it just crashed when loading even though I had charged it. I figured the battery was bad and bought a replacement on Ebay, The power socket had been loose for awhile and the whole thing actually fell out of the tablet when I took it apart. I had the socket soldered by a local guy at radio shack since I have no experience soldering. I replaced the battery with no problem and now the tablet will not charge. I can not tell if the new battery I bought is defective or just need a full charge since it seems my tablet won't charge with either battery installed. The connections from the power socket to the motherboard look good, but I'm wondering if the repair man could have messed up the soldering. When I put the original battery in, the tablet will boot up for a bit and then die, but I get nothing from the new battery. I left the new battery in and plugged in the charger thinking maybe the indicator light had gone bad, but that didn't make a difference. I just wondered if anyone had some suggestions for me. (I've been taking apart and repairing my own electronics for years now, so I am confident no damage occurred while I have been tinkering). Any ideas are much appreciated! Thanks!
See this thread. If you can boot into the ROM or ClockworkMod, then you can use the awk script I've written to find out what your battery is doing--charging, discharging, full, RSOC, etc.
So what happened was, my original battery died, it expanded and didn't last long anymore.
That's when I replaced it with new battery (from ebay, not sure if I can link it here?).
The issue is, basically my phone wont boot with the new battery.
When I hold the power button, it starts to boot like normally, I see the oneplus logo but then it just instantly shuts down.
Even if the battery is fully charged and the phone is plugged in with charger.
I managed to get my phone working like this:
I plugged in the charger and booted the phone with the original battery, then I disconnected the original battery and managed to keep the phone on, powered by only the charger, then I plugged in the new battery.
That's how it stays on and even shows the correct battery percentage. I've been using my phone like this for few weeks now, but the problem is that I can not shut down my phone. It wont boot with this new battery.
So every time I have to update rom or something like that, I have to put the original battery back. That is a problem.
I have no idea why it wont boot with new battery, cause it otherwise works just fine.
The battery from ebay is colored red and I also have second battery that's called "x-longer". Both of them does this exactly same thing.
If anyone knows what's going on, I'd appreciate if you could take some time and help me. Also sorry for my language, I hope you understand.
Thanks,
Ruuppe
Don't ever trust the battery's from eBay. So many times I've bought 'OEM" or "Original" and been fakes. Just because the wrapper on the battery is the same doesn't mean the battery inside is. Same goes for micro SD's also and pretty much everything else. Spend the extra money and get it through manufacturer. Or a reputable company someone can confirm legit. Send the battery back and ask for full refund.

That's what I did. I got full refund from the ebay battery. And the other one (branded x-longer) is from legit company. The battery works fine and keeps the phone on, the only problem is that the phone wont boot with it. What causes this problem?
Edit: Also, the original battery isn't red like the one from ebay, it's black with some silver.

Hi, sorry for delay on answering. I contacted the customer support, and they said they wont sell original batteries nor you can't get them from anywhere.
They also didn't know why my phone wouldn't boot on these replacement batteries.
So, if anyone has any idea, I would be more than happy to know what it could be.
Thanks,

I have no active warranty as an Aliexpress seller(3+ years a seller) vanished at Christmas. I've no issue taking it apart if I need to replace the battery. Watching a Youtube first dismantle video it appears I need a BN41. I'm going to go presume that my local multitude of phone shops won't stock that battery as I tried two and one asked "How do you spell that?" and another "a what phone?" so I won't be going down that route again.
Only reasonable price I could see online was some Eastern European country and using Google Translate I find these charge about €27 for the battery but it's not in stock anyway. Another is €48 in china. Seems a little expensive considering a Redmi 3 battery is about €7.
Anyway I'd prefer to see if it's software leading into a hardware problem as well before venturing down the route of battery replacement.
Any help would be greatly appreciated.
Brought phone into Repair Shop in my City and asked(phoned few days before hand and no problem changing battery) and it was fine until he says "Supplier doesn't have your battery" so I've to go off an buy a replacement. He says that if the phone will show the battery the connection between the motherboard and the battery is not corrupted as such. I'm also looking at "Chargebattery" in the Engineer Mode under Battery and I can see the following as well
ADC_Charger_Voltage :[4626 ]mv
Power_on_Voltage :[3400 ]mv
Power_off_Voltage :[3400 ]mv
Charger_Topoff_value :[4100 ]mv
FG_Battery_Current Consumption:
[XXX.XXXXXXXXXXXXXXX]ma ---------The X represents the consumption as it's going from about 230.0000 upwards to about 462.00000 and fluctuating.
I've had to order a Battery from Spain(exact spec battery BN41) and also bought a Micro Precision Toolkit and none of my tools are small enough to get those screws. I can see all the stripdown tutorials but alas none of them referred to the exact size of the screws so I ordered a Multi-tool. Hopefully it is just the battery otherwise it's the cost of the phone, battery, little multitool down the drain.
I did a very small driver to get one of the screws out(not exact fit) but the other wouldn't budge and I don't want to thread the head on the screw so backed off for now.
Same battery issue w/ Redmi Note 4

Hey BertieBaron, I'm having the same issue with my Redmi Note 4, I've bought a new battery from Iberaccess, opened the device and installed the new battery piece but it didn't solve the problem, still switching off as soon as I unplug it... it's driving me nuts!
Have you found a solution in the meantime? I'd be very glad to hear from you mate.
Cheers
Nope. Binned it. One Plus3T arrives by DHL in a few hours.
Emailed Xiaomi offering to pay for repair. They said No.

Gotcha. May I know whether the charging problem emerged after a fall, water damage or out of the blue?

Confirmed to be no Water Damage by somebody with more experience than I. Was it dropped? It was a teenager so anything is possible but there was no evidence of such.
Yes guys i had the same problem now, stuck at zero Percent there's a RED light indicatingit's charging but still ZERO won t go up ...and once i unplug the phone from charger it turns off Instantly ....I foudn the Solution for that it s quite easy as u think .. all you have to do is :
1-unscrew the 2 screws bottom
2-becareful while taking off the cover u need to take off the Sim tray
3-and slowly take off the over there s the finger print sensor cable unplug it
4-once the cover is off u see 2 cable next to each other one of them is for the battery ...Doesn t matter remove them both and hold power button for 20 seconds
5- make sure u do keep holding the power button for 20 seconds .....do that like3 or 4 times to make sure no power is left inside the phone ..
6-plug everything except the sensor and power on the phone and check this worked for me
Once u see it worked turn the phone off and put back the sensor and get everything back to together .....Don t plug the sensor while it s turned on i have no idea if this damages anything!!
Hi everyone, I meddle in the discussion, I have this problem. I have a Redmi Note 4 Global, a few days ago it turned itself off. I tried to turn it on again and it worked, then obviously the battery ran out. Tried to charge it, the screen turned on with the "mi" logo, red led at the top but it gave me completely empty battery with no percentage. I thought it was the dead battery. I changed it to a new one and put it in charge. Now I see Mi logo and 47%, it does not charge the battery unfortunately. Stopped at 47% for hours. The battery therefore does not charge. Even if I connect the phone to the PC, the charge does not start and the PC does not recognize it. What could be the problem?
Thank you

The seller assured me that the circuit is good. In the reviews people didn't complain about the fast charging problem.
I am using the original charger and before changing the charging port, it charged normal and fast.
In what sense to change ROM?
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!
