Hardware or Software-level Problem? [Battery Issue] - Xiaomi Poco F1 Questions & Answers

This is bugging me for such a long time now. I've had this problem for such a long time. The issue is that everytime the phone reaches 100% of charge, and leaving it for a while (maybe like 5 mins-ish?), The phone suddenly reboots (hard reboot not soft-reboot) and continues to charge but in the idling turned-off mode (only the battery logo is displaying).
Solutions I've tried but didn't or barely work:
Replacing the Battery itself
Switch to different Kernels
Switch to different ROMS (MIUI, AOSP, OOS etc.)
Full drain to 0% and charge to 100% while off
This leaving me confused af and irritated because everytime I want to charge my phone overnight or I just want to leave my phone charged all the time to minimize the battery degradation, the phone reboots completely out of the blue, letting me miss the notifications that I haven't read yet. I need help on this please.

I'll try that one once again, after I backup my files on my phone, and update once I've done it, and see if it helped or not, thanks for suggesting

You are welcome

Unfortunately it doesn't solve the problem. The issue still persists

you need to take the device to the service I guess this is not a software problem

Probably an issue with the board already, either due to a fall or maybe the device you bought may have just have been defective. I would have suggested that you brought it to a service center (since you said you had the issue for a longtime then maybe you could have had it serviced while it still had warranty)

Oh I forgot to mention, yes it may have been a long time issue, but it just started to happen right around 3 months after I bought it. I bought my phone brand new last year, and it didn't have the issue I'm facing now. Sadly, the warranty doesn't cover the battery issue, since I just bought it form a random retail store (not Xiaomi)

Sorry to hear that. Well, it would be best to have it checked by a repairman by this point since based on all the info you've provided you've tried all the troubleshooting steps software wise, so it may be the board by this point. Or if that random store offered you a repair warranty (most rando stalls in my country has that, not sure about yours) then you may swing by there

what about charger?
seems like the only thing that you didnt check

Well if it's a hardware issue from the board itself, maybe I'll just pass for now. The repair warranty though doesn't really cover some major problems like motherboard and battery, it actually needs to paid so ig it's a no for me. I'll just replace it myself over time if the board breaks itself.

I had no issues on charger either. I used a different Xiaomi charger from another phone, and the battery issue is still there. I even opted in using a samsung charger with usb-c, and still the problem persists.

[Q] Guarantee repairs

I bought my GF an HD2 from flebay, brand new, you know the type of ad "unwanted upgrade".
OK OK I know
It hasn't been blocked so the account is still running OK (seller didn't like the HD2 wanted cash to run an iPhone on the account)
Problem is, after 9months the HD2 has started overheating and rebooting when using data or GPS.
If My Location tries to update it reboots, sometimes goes into a continuous reboot loop, only taking the battery out will stop it.
It gets very warm around where the sim card is when this happens.
We've tried a hard reset, no different
Question: Will HTC honour the guarantee (less than 9mnths old) when I'm not the original owner or should I send it to a repair centre and cough up (I guess it needs a new Mboard )
Has anyone been in this situation?
Have I now got an unsaleable brick?
Thanks
I doubt it, have you tried the latest stock rom? that might change the way it runs
Or a not stock rom and radio from this site?

Hi, thanks but I'm pretty sure it's a hardware fault
You've checked for a bent battery pin?......

Yep, and cleaned the battery terminals, tried a different battery (out of my HD2).
The phone works OK if we cool it down by leaving it in a cold room for a couple of hours, but then as soon as it gets some hard usage, long phone call, data, GPS it starts to heat up and reboot again.
It just occurred to me we haven't tried a different sim in it, might try that and see if it's any different!
EDIT: GF hasn't used the phone for about a week now, now it won't get past the white HTC boot screen, just continuously looping.
yes they will honour it , i was in exact same situation and they told me it was 100% covered by the warranty , although the blanket email said to include proof of purchase customer service told me not to worry about it . had it back within 5 working days.
definitely sounds like the motherboard. Same problem with mine. T-mobile bought me a new phone.
I think the warranty date period is based off of the imei and when the phone was shipped out. I would call htc and ask. Couldn't hurt
Thanks for the replies, I suppose it's worth a try.
I'll let you know how I get on with HTC
Fixed
Update:
We sent our HD2 back for repair, HTC picked it up and returned it no charge.
Motherboard replaced.
Fault described on the repair document as "MB Current leakage, battery overheat, MB replace."
Totally excellent service.
Thanks HTC we love you

[Q] Phone keeps shutting down

Hi guys.
My phone shuts down at random moments. I can boot it up again by holding the power button for about 10 seconds. Sometimes, not always, the phone feels hot and batterylife dropped. I have been struggling with this problem ever since i got this phone. I hoped to solve it with installing a new kernel and rom. I am now on Slimbean 3.1.0. The phone was initially on XLQ6 4.0.4. This didn't change anything, unfortunately.
I have also tried:
- removing external SD
- placing a new battery (which has no room to move, in case anyone suggests the battery might be moving)
- wiping caches
The strange thing is that my friend has bought his i9100 together with mine in the same order. He is also on XLQ6 and is experiencing the same issues. Less often than me, however.
My smalband is still on XLQ6. Is it possible that this causes my problems? Or is it more likely that my friend and me simply bought phones from a bad batch or something (hardware related)? I really don't want to send back my phone. That is my absolute last resort.
EDIT: Problem solved! Installing the application "Load Monitor" and enabling the "wake lock" function has done the trick. No more shutdowns or reboots!
Anyone?
2 devices with the same issue?
I'd be at the store where I bought it right now.
I will do that when I am absolutely sure that it is hardware related. However, if anyone has a potential solution I would really like to solve this issue myself.

Same with me. change from 4.0.4 WLPT to 4.0.4 WLPY but problem still presists.
Does anyone know if changing smalband (if that is possible?) could make a difference? Because that is the only similarity to the original state of my phone. A lot of AT&T users in the USA experienced the same problems also with 4.0.4. However, nobody can come up with a solution.

If it is heating near the camera, it's facing death soon.
If it is new and warranty isn't voided, why not flashing the carrier ROM and get a new one?

Because I don't like to lose my phone for a couple of weeks. And I prefer to fix these things myself. I have seen so many topics about this on XDA and Google. There must be a solution to it.
Is it possible that these problems are caused by my modem? That is the only unchanged thing since I have had this phone.
I might have found a possible solution. I've read something on a Dutch forum about sim-cards causing these issues. So I have placed a new sim-card and the problem hasn't appeared in the last 3 days. Before that, the problem was occuring about 3-6 times in one day. It's too early to say this has solved my problem, but it definitely made a difference so far. If it keeps functioning perfectly for the next couple of days I will close this topic.
Symptoms were merely reduced. Phone still shuts down approximately each 2 days. Much better than it was before though. Why would a sim-card change reduce, but not solve the problem? This is starting to hurt my brain.

You may experience sleep of death. What WiFi chipset do you have? I had the same issue on a Murata Wi-Fi chipset.
Yup, Murata chipset. I've googled some more on SoD. I have now installed an app called "Load Monitor" and enabled Wake Lock in preferences. This should prevent the phone from going into deep sleep, apparantly.
Some portugal carrier had a problem with lte sim card or something like that.
I really don't see how a sim card can actually mess with a phone.
Maybe the enabling of some features screws it up.

In my case Samsung Service Team replaced the motherboard. My new MB has a Samsung Electronics wifi chipset. Two weeks now and no SoD.
That sounds good. However, ever since I have installed Load Monitor my phone runs fine. It drains approximately 40% of my entire battery, but it lasts easily until the end of the day.
But again, I shouldn't get too excited. Sim-card change seemed to work in the first few days as well.
Will be continued...
It has been over a week since I have installed Load Monitor. My phone hasn't shut down once. Problem appears to be solved! I hope more people will read this topic, because I have seen a lot of desperate people during my search to a solution.
The only disadvantage is the battery usage of the application. I now have approximately 40-50% at the end of the day instead of 60-70%.

[Q] Frustrated with desire x

I have posted before too on this issue of random reboots on desire x. It seems that i am the only one who have faced random reboot problem multiple times a day( varies between 1-10).
Now i would like to explain my issue in detail. These restarts DOES NOT occur when i am using the phone and running multitude of apps.
It only occurs when the phone is lying idle or when charging. Sometimes it reboots with white HTC screen while sometimes it gets stuck on a black screen( not switched off), in latter case i have to long press the power button to reboot it again. I can't even leave my phone alone while charging because it may crash which will result in missed calls and messages. The phone worked fine for first 4 months of purchase so may not be hardware related. I did upgrade my software twice from 1.18.401(factory) to 1.18.720 . the latest update was 1 week before the problem started.
I did not spent my $400(Indian price) on buying a buggy phone which bothers me and left me wondering why is it behaving so strangely.
The trouble shooting i performed in last month includes -
FACTORY RESETTING 5 TIMES
RUNNING PHONE WITHOUT SD CARD
RUNNING WITHOUT ANY APPS INSTALLED
PUTTING A WEDGE ALONG BATTERY TO ENSURE GOOD CONNECTION
SCRUBBING BATTERY AND PHONE CONTACTS
USING PHONE ON SEVERAL SIM CARDS
The problem may be network related, i don't know.
I am so disappointed in HTC. Is anybody here on software version 1.18.720 and not facing problem of reboots. If the update is faulty HTC should come up with another one.
I am on a sabbatical and 300 miles far from nearest service station for another month.It makes no sense to cover 300 miles and spend hell lotta money just to get this goddamned thing serviced. My last hopes are on Jelly Bean update to solve this problem which seems to take forever in coming to Asia. Is there any way to go back to 1.18.401 which came natively with my phone or some other way to resolve it.
Thank You
Get it replaced in Warranty. THE JB UPDATE WONT SOLVE THIS ISSUE. As it is specific to some users and not others, so its not a SOFTWARE issue. Its Hardware Fault. Get it replaced ASAP.

Let the warranty guys wonder why the issue happened. Its a costly thing, and warranty is EXACTLY for these type of situations. USE it.
Just save yourself the hassle and get it replaced like nexus suggested if you dig into what the causes are it will take a while because i tried to with an older htc device
Jb wont solve it, if its kinda similar to my problem described in your previous thread, motherboard change is the only option
thanx everybody . so that means i will live with this faulty device for sometime more till i go back to my work place n have access to service station

Thats awfuly bad luck... cant you send it via mail to service centre? In czech republic, there is this posibility (and we are around monkeys level here in whole smartphone situation).
I also have 720.3 but don't have such problem.
That's absolutely a hardware problem,take it to service center asap n dont wait for jb update.

YEA may be i can but that will take forever in India to get a proper response from main htc office/SC that is 3500 miles away. I will be in bangalore in may/june so will directly go the main service centre myself. Additionally I don't think they will replace the phone immediately so sending over mail will be useless if i get the same phone back with some temprory tweaking from their side.
I have 6 months of warranty left till November so if it goes bad let it be, my case will get stronger.
Can i flash my phone back to 1.18.420 myself without voiding warranty.?
In future i will think twice before going for HTC
i read somewhere in forums that android phones also need to cool down for sometime and periodic reboots or what they probably meant is switching off the phone for few mins is essential for long life of the phone but may be its just me

RANDOM REBOOTING devices with STOCK ROMs have FAULTY HARDWARE.
I phone shouldnt reboot on heat even with extreme use, and if it does, its faulty.
If you have custom roms or kernels, then it might be due to software issue, but on STOCK, its always HARDWARE.

You remember me about my old Mio A701 phone who started to behave strange for month or two... and after that the radio chip crashed...
Also it happend on my wife's LG phone that a little dirty (mettalic I think) on circuit inside right behind the power plug was able to freeze the phone and some times to restart.
So, if you tried all that things and the problem is not solved then it is a hardware problem! You have to disassemble the phone and repair it! Or go to service center (never I had).
its not a heat problem coz .i can use this device for prolonged sessions. only when the screen is off and network on it reboots
PS. when is jb coming to India
Try one more thing there is a app(don't know name) which can increase the minimum processor frequency
Try that out may be your CPU has very low min speed, don't sure about this but give it a try.
If that requires rooting then don't do it.

Charging issue after lollipop update

I upgraded to 5.1 the other day using the package offered on Huawei's own site. Had to use the force upgrade method, which I did while the phone was plugged into an outlet using the factory charger. Since then, my battery has crapped out on me. I left it to charge all night and when I woke up it was still stuck at roughly 30%. In the span of two days I have tried multiple chargers and performed a factory reset. Somehow I managed to charge it up to 78%, but now it's stuck at that percentage. Anyone have a clue what could possible be preventing it from fully charging?
I have not seen this or heard it from anyone else. Maybe your hardware has an issue?

That's what I was thinking. As 322 rewrites pretty much everything coming from 4.3. The batteries are hard to replace. But it is doable. Someone posted about doing it. And there is a video of it being done on YouTube. You could also try reflashing 322 first.
I've read one other report on the Huawei forum of someone having a similar issue, except he is able to recharge only after the phone has been discharged to 9%. My thoughts are maybe there is some kind of power conservation trigger or something? I've never had any problem charging my phone to 100% prior to installing the update. If it is a hardware issue, it chose the perfect time to malfunction...
I'm gonna try to downgrade back to 4.3 and see if the issue persists.

That should work to. First i have heard of it on stock ROM. Still may want to try reflashing 322 first. Then4.3. Some ran into issues reverting to 4.3. The file system changes evidently can screw up. Let us know how you resolve it in case someone else runs into the same issue.

Just curious, I'm completely new to android, but could you possibly point me in the direction of how to proceed with reflashing 322? Gonna try it when I get back home from work this afternoon.

That thread has everything you may need in it. Just download the 322 update to your SD card and boot holding down all three buttons. Volume up and down and power. Let it run. Here is Huawei official page with the download and the instructions.
https://community.gethuawei.com/sup...15/06/30/mate2-android-l-update-now-available
I think you probably already did that, but want to mention it regardless. Have you tried turn off phone completely, the boot up and charge? Also charge it when phone is off? I am saying this because the other days I learned reboot the phone is different from turn off then turn on.
Tried downgrading to 148 yesterday, woke up with a 25% charge, same as it was when I plugged it in last night. I also tried the above recommendations for charging while the phone is off, restarting, etc. I have scoured other forums for this issue and found similar stories with other model phones. I'm now thinking it's a hardware issue with a mechanism that senses the battery's status.

Very odd indeed. Have you tried completely draining the battery? Then charge while phone is off.. Is it still under warranty?
I have had luck disconnecting the battery, rebooting on outlet power and reconnecting the battery.(this WILL VOID your warranty) Not gospel thou, could have been luck. Reflash if you didn't already first. There are some screwy things that happen, I for instance have a phone that I cannot get back to JB for anything. When it boots it uses stock android bootanimation from system/bin not /cust folder.
If you replace the battery peel carefully or you'll break the LCD.
I don't think its battery thou.
Yep. Tried all of the above. After downgrading to 148, the phone wouldn't even charge even while plugged in. Fortunately, it is still under warranty so I'm sending it in to be serviced...
Unfortunately for me, the entire reason I bought this phone is because it is unlocked and I am leaving for Germany next friday. I bought it hoping to be able to plug a sim from a local phone co. overseas and just go. Now I'll probably have to get a relative to ship it to me after they finish repairs.
And by the way, I initially installed B322 using the forced method. I didn't think it would make a difference. Guess I was wrong.

SM-G850F power issues

Hi,
I have a lot of trouble with my wife's Galaxy Alpha phone.
Sometimes, it switch off alone.
Last time it was when charging, it starts to charge for 5 min, then switch off showing the logo during switch off, as if it was requested by software (not a battery problem).
Sometimes it restarts normaly as soon as I press the power button (boot normaly), but sometimes, it bootloops.
I found a workaround for it, having to press the power button until complete boot (asking pincode), then releasing the power button and entering the pincode, and it works normaly, for some days.
Seems pehaps an hardware issue ?
This starts a month ago, without any related causes.

First try to flash stock firmware with odin.
If this didn't help it's very possible to be a hardware problem.

You flashed after the "power issues" appear or before?

In fact both.
It appears first time when I was using the original rom.
Then I flashed a new rom using odin.
It worked without any problems for a week, and reapered.

Yeah sorry, but I think it's a hardware problem... Try at a service, maybe it's something simple and costs less.

The shutdown seems to be related to Google Play. The phone shutdown when updating some applications through Google Play !
Is there a revert to stock google play application and force it to never update again ?
Seems that the latest version of google play have some troubles.

I didn't encountered this issue on my alpha, try a factory reset.
Battery issue, maybe....?
I have an old battery and the symptoms are similar. The efficiency is no longer the same and sometimes it turns itself off suddenly.
My other battery is newer and it doesn't happens.
These batteries are fragile and lose reliability quickly (most noticeable after a year, depending on usage).
Seems that I have fixed the problem. A hardware one.
After opening the phone... completely so that able to manipulate the motherboard I found that the small connector to the power button was not correctly fixed.
After a deep cleaning of all the contacts on the motherboard and fixing the connector I reassembled everything.
It is now working well for more than 3 days without any issues.

Glad to know that you fixed the phone.
Finally, after one week, dead again...
I think that the only solution for me is to replace the motherboard.
Changed the motherboard with a new one bought on AliExpress. Everything fine now.

I bought a new mobo, now it works perfectly fine, I actually bought two just in case I broke something while installing it, but first one is good to go, experiencing some drain issues tho with my old battery tho, so i have to recycle that. Any way, it all ended well and now I got another mobo incase this one breaks ^^

Greetings. My Samsung Galaxy Alpha is dead since 2016. Not charging, not turning on. If possible send me the exact AliExpress seller link. One more thing, is it possible to find the front facing camera of this device? When i give my device to a technician he lost the camera. The camera was 2.1 megapixel.
