poco f1 battery issue - Xiaomi Poco F1 Questions & Answers

hey guys. I have been using my poco f1 since launch flawlessly. but few weeks after lockdown started weird stuff is happening. phone won't connect to my both laptops. it won't charge while booted in the rom. I have to switch it off to charge. but the charging speed is very low and in the last few days battery drain is terrible (40% overnight - mobile data, BlueTooth, wifi, GPS all turned off). is this a hardware problem or battery problem or do I have a damaged USB cable(braided USB c bought in mi.com)?
ps: I have been on pixel experience the past few months
thanks in advance

Looks like either a problem with poor USB cable or damaged/dirty charging port. You'll have to eliminate issues one by one. Use Isopropyl Alcohol and a wooden toothpick to clean the port (don't use metal). Borrow someone's charger and cable and see if the issue still persists.
Please upload screenshot of your battery graph.
Also install Better Battery Stats (grant adb permission) and check what's keeping your phone awake.

You have to do the most basic of all troubleshooting. Eliminate each possibility. Start out with the most easiest to solve, use a different cable. If the issue persists then try connecting the new cable to a different brick or a PC. If still persists then it's likely the ROM, check if there is any rogue app via battery menu or try booting to safe mode and see if you can find the rogue app. If no rogue app, then it may be best to reflash (backup then reflash).
That's about it. If all else fails then go to a professional technician or talk with a xiaomi store that has a repair center to see the phone further.
Again basic ts. It will solve a lot of problems.

A116 Charging issue

For past few days, I'm facing this strange problem that the phone doesn't charge beyond a particular limit, and sometimes at all. When I plug in the charger, it displays 'Charging' but the battery level doesn't go up. I tried few things to understand where's the problem:
1.) I changed the charger and used the other ones (700mA, 500mA, USB charging with PC) and they worked well for a while, although slow charging, but afterwards the issue re-appeared and phone stopped charging even by them.
2.) I changed the battery, thinking it's a battery issue. The one that I got from a friend charged perfectly well with my own MMX charger for the first time, but now it's giving the same issue again and not charging beyond a particular level, say 40%, which will eventually come down and it won't charge at all.
I'm confused as what kind of problem it might be - hardware issue with the charging socket, charger/USB cable issue, or a firmware issue? Has anyone faced this problem till now wherein the their phone doesn't charge, even though it shows 'charging'? Please share what did you do to resolve it. I'm currently located at a remote place and cannot visit a service center.
how old is your device? if it's more than 9 months you might have to replace your battery. you could find it on ebay.

Phone is charging slowly

Hello all,
Recently I got a problem with my phone. A couple of weeks ago it started displaying charging slowly when connecting it to the power supply. In these cases charging takes hours to charge the phone completely, approximately 5 hours. Few times it says charging fast, and then it charges in about 2 hours. At the beginning I got the impression that it has something to do with the angle I plug in the cable, but it's mainly random.
Now I'm a bit afraid the phone is broken. I've already tested different power supplies, even the original one but it didn't change a thing.
I also tried using cm13 and the current oxygen, no difference in behavior. I even installed a different kernel, without success.
Do you have any idea what's causing the problem or if there's anything I could try?
Thank you!
@StarFishes82 maybe there's some lint or crud stuck up in the port. Use a toothpick and gently sweep inside.

I have experienced that different cables have different charging rate. I only can recommend to use the original cable or some better quality one which can handle 2A, but I assume you are using the original.
I can feel that since I am experiencing same problem. My phone is not detected on computers too. It isn't detecting on my Mac. tried on Windows machine too and unrecognised/Corrupted device connected message popped up. For now, I have flashed Boeffla Kernel (OxygenOS 2.2.0-X) and using its app(Boeffla-Config V2) to increase charge rate(Not recommended, phone heats a lot if you charge and use phone same time). My phone is charging in expected time but this is not permanent solution for this problem. I am taking my device to service center this weekend and recommending you same. Hope they cover this issue in warranty.
Just wanted to give some feedback.
I tried everything mentioned above, without solving the issue. The physical port is clean, I tried different cables, finally I contacted the support. I have to send them the phone and they are gonna repair it. So bad luck because I have to find a temp phone...
Hello Dear,
I have encountered the same problem as you today, but my phone is Sony Xperia Z2
Same problem exactly.
Charging Slowly (5 hours until full)!
What to do? Is there any fast workaround? I'm afraid the warranty is gone, can I fix it in any store?

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.

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!

Battery Issue

Hello People,
I have started facing this weird problem with my Mi A3 yesterday that I only bought in June.
The problem is the phone does not charge. When connected the charger, it shows "Charging Slowly" and the battery percentage stays as it is. It has been plugged in for 8 hours now with no change in the battery percentage.
Ampere shows a charging current of 70mA while the same charger & cable on my wife's OnePlus shows 1800mA current. So it's not the charger! :crying:
I have tried a hard reset, I have tried 4 different charger & USB combinations, NOTHING WORKED.
Any help around this will be greatly appreciated!
I will be set back with 15K if I loose this phone
What about the charger in the box? Doesn't that work?
Sounds like a hardware problem to me. Try going to the customer care
Thank you for a quick response!
None of the chargers are working. I've tried stock, OnePlus Dash, Moto Turbo, Samsung, everything.
I guess, service center is the only thing that can help.
Update - Even when it is plugged in, it keeps discharging.:crying:
Sadly, service center is closed, I'm from Pune and the city is in a lockdown till tomorrow.
Update - After a lot of struggle to not to reset my phone and an extensive research, I have wiped my phone clean and viola!
The charging works, it still charges slowly, but that's not as slow it was earlier.
I remember it seeing on screen 8 days untill full charge!
Now it's 6 hours to full charge, even with a turbo charger, 15W.
I will keep digging and posting the updates here.
Thanks
Charging too slow... battery draining out fast
I am facing same issue with my mi A3 since yesterday. It is taking 8 hours for my phone to get fully charged also battery is draining out too fast. Seems like this issue arrived with July security update. Even I tried hard reset and several other chargers but issue still persists. Hope that Mi sends out bug fix soon.
Resolved!
I had to visit the service center within a month of purchase due to the above mentioned issues.
Apparently some electronic failure caused the connector to fail and stopped the phone getting charged up.
My device is under warranty and thanks to that, got the faulty parts replaced for free and within 2 hours.
Which hardware parts did they get to replace??, Also facing the same issue

Hey!
Sorry about the late response!!!
They changed the charging port, as my device was in warranty, they did not charge anything!!

Poco Pixel 11 Plus Rom Loop Wont switch on

Greetings,
I have been using my poco f1 for 4 years now and it has stood by me strongly. I only replaced the battery once due to excessive usage from covid (hotspot on almost 12+ hrs of the day).
It had pixel plus 11 rom in it and I was very happy with it too. Over the past 1 week, i noticed it was behaving strangely.
1. The charge time took almost 3hrs even though it showed charing rapidly
2. When I switch off the phone and keep it for the charge, it charges comparatively faster.
3. At certain times, it would freeze and restart.
4. Would heat up during charging, so I would keep it near a window or anywhere there is a breeze so that it doesn't overheat.
As of yesterday, the phone went into a complete loop after charging (It was off while being charged, once it reached 95% I unplugged and switched it on) with poco symbol followed by the 'G' icon appearing.
I thought i'd wait it out, but no luck. The weirdest thing was, when i reconnected my charger (Charge ON), it would switch on. And when i'd unplug it, the phone would switch off and go back into the loop.
The phone was near full charged, but i figured this is probably a rom issue and needs a good flash. So, I plugged the phone in for charging again so that I could switch it on and then took the necessary backups.
In parallel, I downloaded the latest rom (Pixel 12 stable build) thinking that if i flashed it would solve everything.
I connected the phone via USB to the laptop to copy the rom file, but it didn't swith on. It would only do so by charger. (Weird!). I tried it a couple of times, and managed to switch the phone via USB cable connected from laptop. But it didnt last for long as the phone would switch off shortly. Fortunately, it was on for just enough time and i mean, a couple of times till I could copy the file into storage for flashing.
I reconnected it back to the wall charger, switched on and took backups. At this point the phone has reached 100% for about 2hrs or so, but there's nothing i can do in order to get it to be on.
I proceeded to flash pixel rom 12 via twrp after clearing the cache, davlik and all of that. It was successful (no error messages appeared) and when i rebooted it I could see that the rom went through fine as the charging '100%' icon has changed (Its more graphic) but the phone still wont switch on and continues to be on this loop.
Can anyone please advise me on how I can tackle this? I dont want to buy a new phone as I feel there is nothing out there that would match this phone for its value. (I can use pixel rom, good battery, durability)
Any help in this matter would be highly appreciated.
I'd be more than happy to make a contribution to anyone who can provide me with a solution that works. I'd rather be happy with my old phone and you can treat yourself to a nice meal rather than having to buy a brand new phone. (So far, im looking at mi 11x, s20 fe, mi 11 lite, oneplus 9R, but to be honest they just don't appeal to me. You know what they say, once you go poco, you go loco!!!!)
Thankyou
Be safe

Firstly make sure you followed this installation guide.
Then if you are sure that flashing is correct, I think it's your battery issue. You should replace it.

Hi there!
Thanks for replying!
I tried the same out all day yesterday and had no luck.
I have given it to a mobile repair shop nearby (we have a separate market for mobiles here).
Hopefully they can sort it out or else I'll go for a used S20 FE 5G, saw a couple of them ranging from $300 - $400

You could just buy and replace the battery by urself with 5min YouTube video
In repair shop they may ask extra money or try to show u that needs more than battery.
I am sure it's battery tho.

Hi there!
Thanks for replying. So, my phone did get fixed, apparently, the issue was due to the charger port and battery connection. Somewhere there was a short circuit causing that issue.
They mentioned this happens due to overcharging or using the phone when on charge or running heavy applications.
Yes, a battery replacement would add a few more hours of battery life I'm sure as I currently average 6 hours on heavy usage.
I plan to use this phone till it no longer runs as the alternatives out there arent really all that great with respect to value for money and reliability. I hope to get my hands on the mi 12x, it looks really appealing!

I am glad you found the problem and you got it fixed
For sure hardware of POCO F1 is still good and worth the money. Enjoy the paradise of custom ROMs
