I am amazed that nobody has highlighted the actual problem behind all the below mentioned issues. It has been 3 years since I bought this device and has already replaced 3 batteries. Everybody said the same thing that you need to replace your battery. My batteries looked absolutely fine when I removed them from the phone. Not a single one of them was swelled or had low battery health before I started experiencing this issue.
This fix is for all the people who are having following issues with this phone.
1. Your phone is restarting when you're using camera app or any other app.
2. Your phone is restarting when you have maximum brightness.
3. The speaker of the phone is producing crackling sound when the volume is at max.
4. Phone is continuously restarting and can't pass Android logo.
5. All the above problems are not happening when you're using it while charging.
The culprit of these issues is the fuse in the strip of the battery. The resistance of that fuse increases with time and your phone can't get the desired current it needs to run the device smoothly. Hence, the restart issue. PLK will be written on the damaged fuse. You just need to remove that fuse and use a jumper wire instead. ANDD your problem is FIXED!!
I have attached the 2 pictures. Please keep in mind that the picture in which he used jumper wire is of some other phone battery. It is for reference only as I couldn't find one for Nokia 8. You need to do the same after removing PLK fuse in picture 1.
Do the above solution if your battery is not swell when you remove it from the phone or it was working fine before this issue. I have already replaced 3 batteries before I came to know about this fix. I was curious because all those batteries never swelled and was working absolutely fine before this issue suddenly arises with each battery after some time. Now, my phone is working absolutely fine. I Hope this fix will save you guys some bucks
Thanks man! That'll be useful for all of us at some point
Is there any risk with the battery (fire while charging) once the fuse is replaced by a jumper ?

If you can find a new fuse then replace it. Else, the jumper wire will do the same work. These jumper wires are very thin and will break easily when excessive current pass through it. Make sure to use the wire which matches the properties of this fuse.
Thanks, all of the listed issues are also the same issues I've been suffering with my Redmi 9 https://forum.xda-developers.com/t/...ots-by-maxing-out-the-volume-and-etc.4520827/ . Before seeing your post I have seen youtube vids and some quora stuff https://www.quora.com/Why-my-Redmi-...hare=63e75d89&srid=iCufI&target_type=question highlighting that the main culprit is the fuse within the battery's management circuit. Glad, I've seen a related xda post.

Hi, I have recently acquired (mid Sept. 2007) a TyTN II device: really a very good and nice device ... till yesterday.
Maybe my experience could be shared with some of you...
Yesterday my device suddenly turned off apparently because battery very low (i.e. less than 5% according to the manual): this is strange because as far as I remember my battery was charged enough to survive more than one day considering that I did not use Wifi/Bluetooth or many phone calls.
By the way, the problem occurred when I attempted to recharge the device: it spent hours under recharge but the power led never become green, but remained orange. I attempted anyway to startup the device, but as soon as the Windows OS started it automatically shutdown because battery too low was detected.
I performed several software reset and finally an hardware reset, while attempting also to recharge it also via USB but without any positive effect.
I contacted HTC which suggested me ... to provide back the device most likely for being replaced according to the DOA (Dead On Arrival) policy.
Please note that according to some tests I performed on the battery, this seems to be charged and the problem relying on the device or OS which do not recognize it as charged but so low that no operations are permitted.
Has some one experienced a similar issue with this new HTC device ?
Cheers,
Max
GF's 8125 did almost the same thing; wouldnt charge past 10% and kept sending notification after notification; this was literally right out of the box. Cingular/AT&T suspected the battery but replaced the 8125 as well.
So far I have not seen other reports of this for TyTn II. It is however a reasonably common problem with many different brands of phone.

Could be a Power managment issue its not uncommen at all. things go wrong in all electronic devices think of the millions of Kaisers that will be sold in the coming months a few are bound to messed up from the factory. Its like buying a car you know ****s guna happen but you buy it anyway since it looks really nice that first day!
Did you all charge using the supplied wallcharger instead of via USB?

Make your kaiser power off, and use wallcharger. If it still doesn't work, call for HTC..
Some problems are solved by letting the internal battery drain, by leaving the device without the battery for a couple of days.
That issue can happen if you (almost) run out of battery.
Best practice: NEVER EVER run down your battery below 5% ! As soon as it reach 10%, switch off if you dont have charger at that time.
You might go below 10%, but take the risk .... !
It is known to us that the new Windows Mobile 5.0 supports persistant memory (your data will not lost when the battery runs out 0%), but it does not say that you will not be able to charge the battery!
More explanation? And how to revive the battery?
Read this thread:
http://www.modaco.com/Warning-Battery-Chargin-t233233.html
It is well explained, how that happen and how to recover the battery

ey man, i followed the recommended procedure for the three firsts battery charges. First i plug the PDA and let charge at 100%, then i let the battery goes to 0% (yes, the PDA goes off, of course) and then plugin onto the wall charger, and let charge to the 100%, repeating this procedure three times.
I do this also with my previous PDA, Hermes. And no problem leting the PDA going to 0%...never see this problem before.
What is the supossed problem leting the battery goes to 0%?
Regards.
EDIT: Found this interesting information about LiIon... http://en.wikipedia.org/wiki/Lithium_ion_battery and http://www.batteryuniversity.com/parttwo-34.htm
jcespi2005,
I simply dont know I just shared the link that I knew from modaco which is useful in this case.
Maybe this is not 100% the case, but as I said "best practice" ... something that it is better to follow to avoid this issue as you should read already that quite a lot of people affected by this very low depleted battery.

The modaco thread talks about Wizard, i think it's not 100% the same as Kaiser, cause is not the same battery, and the hard charge interface on the PDA can be different. I'm going to make a deep research about model and manufacturer for the Kaiser Battery, to see what can be the issue.
Anyway, i let my Kaiser goes 0% three times and charge fine for the three times. So i beleave the issue is not related with the battery itself. Can be the charger? don't know...
What is the model and manufacturer for your Kaiser battery, please?
Mine is Samsung model KAIS160.
Just checked and I have the same battery, SAMSUNG KAIS160.
I have now seen another report on another forum with this problem (Kaiser). I suggested the standard method as used when the refusing to charge issue arose with the Hermes (TyTn).
(It worked by the way!)
i.e.
1
Remove the battery for half an hour or so
2
With the battery still removed connect and switch ON the official (1000mA) MAINS charger (Not other brands that deliver only 500mA)
3
Now insert the battery
4
Wait for up to 5 mins for the Red LED to change to Orange
Repeat steps 3 and 4 if you have no success after waiting for a reasonable time.
(If that fails then elsewhere I have reported the technique of delivering a charge to the battery using a couple of AA batteries)
My view for what it's worth:
Although in rare cases there may be a faulty battery, in the main the problem is not caused by the battery. The likely explanation is that the circuit that detects the battery's presence, fails to detect the battery when the battery charge is very low. In other words there is no problem with battery but the battery charge detection circuit is either frozen or does not switch on when the battery charge is too low.
This issue I see reported across many brands of phone and is not a WM specific problem.

Many thanks for the information, this confirms my suspects about the interface to the battery, and not the battery itself... i see this issue time ago with one Nokia 6100, and solve it with the same procedure you write. Sometimes LiIon battery gain some charge if you place in the refrigerator for a while (cool helps LiIon batterys, and warm hurts).
Regards.
EDIT: More info about charging LiIon battery here http://www.batteryuniversity.com/partone-12.htm
Seems there is no need to make three charge/discharge cycle before use the LiIon battery. Simply you can use and charge in any moment. Really is better sorts and many charges rather than less and longs charges/discharges.
Power Failure.
Hi guys,
Well the USB did the trick.
Don't forget the Red Wire is the + (Positive)
and
the black Wire is the - (Negative).
A few minutes holding in place did the trick.
Thanks a lot for this thread, I actually had the feeling that I have lost the Kaiser.

Hello,
Take a USB cable (the one like you use to sync your pda) cut it in the middle, expose the wires inside.
The red wire (+) is to be attached to the PLUS of the battery, and the balck wire (-) is to be attached to the minus of the battery.
About one minute and fater re-install the battery and try charging again, this should do the trick.
You can also use 2 AA batteries in the same manner.
Yours,
Ronen
just happened to mine after only a month. Contacted att and the forum and had to get it replaced. So far nothing wrong with this one!

Hi Mike,
Had my Kaiser sent to a lab, they are checking it but they are saying it is a faulty board.
The battery is ok although I bought a new one and tested it to find still the same problem.
Thanks.
This One M7 had been my spare for close to a year. I replaced the screen, camera, and back cover to make it whole again, and everything worked great for a couple months. Unfortunately, it completely died one day while I was using it and the device has shown no signs of life since... until now.
Actually, it still doesn't really show any signs of life. No amount of button holding has been able to elicit any response whatsoever. No charging indicator light either. I've tried leaving it sitting for several months, but this too has not changed anything. I finally opened it up today to check on the battery connection and reseated it. Still nothing.
The one and only response that I do get is recognition on my computer when plugging it in, where it shows up as an "MTP USB Device." Nothing shows up in Windows Explorer though except an empty CD drive.
Any ideas?

you bricked it, maybe flashing RUU can help. if it will not help you can then use JTAG, it can help to flash firmware on dead boards. you can find JTAG on eBay.

I'll try to measure the battery voltage this weekend. Aren't the pins a little small to test with standard multimeter leads though?
0volt multimeter test
I finally got around to trying to measure the voltage of the current battery with a standard multimeter. I got absolutely nothing, which means that I'm either measuring it wrong, the leads are not sharp enough, or the battery is dead. Has anyone else ever had any luck testing this battery with a multimeter?
Going for it!
I tested another, similar, battery by multimeter successfully, so I suspect that it might just be a case of bad battery (at least). With that and the fact that I had a Galaxy Note 2 battery fail earlier in the year, I'm going to jump in and buy new batteries.
Rather than just trying to go cold turkey and install the replacement, I'll test it with the multimeter and then hook it up pre-install. If the phone powers up, then (and only then) will I go through the massive hassle of replacing it. We'll know one way or another next week when it comes in.
Humongous Tinfoil Catamaran!
Just to follow up, I did end up buying that battery. Definitely not "new," but as long as it's in decent shape, it should do the job. While the multimeter test revealed practically nothing, (same as before) the phone did spring to life with the charging indicator as soon as I plugged it in to power. With that, I've charged it up and will be fully testing the phone next weekend. If everything checks out, I'll start the long & annoying process of replacing the battery and hopefully have a fully-working One once again.
Here's to Change!
FIXED!
Just to provide some closure, I can say that the battery replacement was a success! The vibration motor is totally dead (despite being plugged in adequately and not seized) and the casing took a beating from the repeated re-entry attempts, but the phone is now working once again. I suppose I could buy another replacement back cover to really finish the job, but will probably just leave it as-is for right now.
Hi
I have a OnePlus 3T stuck on 50% battery it doesn't go up or down, I tried letting the battery drain and then restarting, but it still displays 50% even after factory reset.
Is this a problem that can be resolved? I am not sure what else to try, I tried battery re-calibration apps and charging the phone a few times etc. but it did not work.
Hope you can help.
Thanks
Infinite Battery life? COOL!
Or did you mean the Indicator is stuck on 50% even when the Battery itself runs out and dies? If that, i can see it being an issue. We should start with the basics. What ROM? Bootloader state? Recovery? Kernel? Firmware? Mods? Length of time since last clean install. etc.
A Factory Reset seems like a good first step for now.
Haha, yes the indicator is stuck on 50%.
If I let it run out then recharge fully as they say to do to recalibrate, then even doing this overnight, it is still (apparently) charging in the morning - so I turn it on and it is still the same thing stuck on 50% and not recalibrated (if calibration is indeed the problem).
I moved to Lineage OS 15.1 (OFFICIAL) using latest TWRP recovery. Bootloader is unlocked.
It is now back on stock (latest build downloaded from oneplus) after full wipe of data/cache/dalvik, with stock recovery (bootloader still unlocked). The problem remains.
So as you can see a factory reset did not work I am afraid.

When it's been on charge long enough that it should have fully charged, it's still showing 50%, right? If you use it long enough to discharge completely, are you getting half the Battery life? (This is the difference between the indicator being faulty and the Battery being faulty).
If the indicator is correct and the Battery is refusing to charge beyond 50%, that's your Battery about to die. Send it to Oneplus for a replacement.
Thanks, yes if I leave it on overnight or otherwise more than enough for a full charge, it shows 50%. It is difficult for me to say if it lasts a full charge as I only just purchased the phone, so I have nothing to compare to.
However, the indicator does not slowly increase to 50%. I can fully discharge the phone until it turns off, and whilst doing so the indicator stays at 50%. I then go to charge the phone whilst turned off, and it doesn't matter how long I charge it for, almost always I turn it on and it is stuck at 50% (very rarely it looks like it's working, it starts lower and the level even seems to increase a few percentage points, going to say 15%, then it stops and I wait a while until it is clear it is not going to change, and eventually restart the phone, turn it back on and it's the same old deal, stuck at 50% no matter what).
I am not sure if this is very helpful, it's difficult to describe, I guess the bottom line is, no matter how long or little I charge it, almost always I turn it on and it is stuck at 50%, which made me think it was some sort of indicator problem, but I am not sure. I guess I should try and send it back as there's clearly a problem and I have tried reasonable steps to resolve.
Probably battery is fried
Damn, that's a shame, if that's the case I guess I should send it back then (although I can see the seller disputing it, I've barely used the device and it doesn't seem to be resolvable so I don't have a choice really).
I suppose I will rebuy OnePlus 3T unless there is an alternative, wasn't happy with recording quality which is a shame as I like to record guitar/singing, but everything else seemed great - I guess a new Xiaomi is another option as no trouble with battery, but I hear recording quality not so good.

I'm sure the seller was perfectly aware of this defect when they sold it. If the phone is in good condition otherwise, and if you got a good deal on it, you might consider getting Oneplus to service it. It's a gamble but it's still a great phone and a new Battery would give you at least two more good years with it. I'm sure we'll still be getting custom ROM support that long too.
Any other 3T you buy used now could face a similar issue any time soon and then you'd be in the same boat.
If it still has a warranty, then it's easily solved through official service.
If not, then if u bought it from a private seller, than good luck with convincing him about the problem
Sent from my ONEPLUS A3003 using Tapatalk
You need to have it serviced. I had that issue shortly after I purchased my 3T. I had tried all sorts of apps to see if it was charging and they all said it was, just not dash charging. Everything showed 50%, every app, any ROM, recovery, everything. Also, if I remember right, the battery wasn't exactly charging while plugged up, it just wasn't drawing juice from the battery. I know they replaced the motherboard but I can't tell you how much that would cost as it was under warranty.
if you are on OOS try *#808* check battery charging .if you get -40C its a problem with the motherboard

For oxy? On custom roms used holy kernel
There are 3 possible solutions for this issue.
1: replace battery.
2: change the ROM for one that changes the Kernel for a version without this temperature protection.
3: fix or replace the main board.
To fix the main board you need to check 2 things on it.
On the left side of the battery connector (under a double sided glue tape foam), there are some SMD. The lowest two are related with this problem. I fix my board resoldering the one on the right (nearest to the connector). Be aware that the SMD is small and when are desoldered, it gets sticked on the double sided glue tape foam. I took a picture of it, but i don't know how to insert here.
If someone is reading this thread today and wants to know the solution,
This problem occurs when battery wire is connected loosely to motherboard or that connector has gone bad.
It has nothing to do with ROMs, kernel etc non-sense.
It's true, had the same problem after switching the battery of my OnePlus3T.
After reopening the device and reattaching the cable by CAREFULLY using more pressure and using a bit duct tape to fixate everything, it worked just fine.
Charging now works as it's supposed to and I'm again able to see the actual charge level.
Thanks lockhrt999!
I see on some sites that users are reporting this and some think that it's related to the security update in March. That seems to be when mine quit charging wirelessly on known-good chargers.
On mine, it intermittently will never handshake with the charger, start to charge then lose connection or never charge beyond a certain point.
Wondering if anyone here is having this problem.
This sounds like the issue people have had with battery connector. There seems to be a faulty battery connector or easy to break small piece. Many have reported this and have had to either fix it themselves, get another unit or pay to get it fixed. Search around you will see what I mean. I haven't heard anything about an update causing this. I have heard that there is a piece that connects battery to phone that breaks easily. I've read quite a few reports of this and how a slight drop can cause it to break and cause charging issues... Read one person put a piece of electrical tape on it and fixed it that way.. idk. That probably doesn't help much. I hope you get it fixed. If you think it's March update and want to rule it out install April update.

Check for a swollen battery. On mine the glass started to separate near the volume buttons. I didn't find it until I took the case off and inspected it carefully. I was able to get a free replacement. There was extended coverage for 4XL battery issues... maybe still available. My issue was not the same as the battery connector issues also documented on XDA.
Erratic wireless charging and swollen battery
This issue is related to the battery, but not the connector issue others are having. About 3 weeks ago I started experiencing erratic wireless charging. Sometimes it would be fine, other times it would just stop for no reason, or not even start...

That was it exactly.
I talked to them and they escalated me to the "product safet6y team" and I'm waiting to hear back from them to see if they will replace it.
I was heartbroken when it lost wireless charging because I really wanted to keep this phone as long as possible and hated that something was broken. It's almost perfect in every way (and no notch or punch-hole.)
I also had the Soli unit go bad and they replaced my phone early on under warranty. I think LG did a great on these as the ODM, but it looks like their component sources were the problems.
Thanks again for the excellent help.
So I was having the same problem. I had to pop the back off my phone. You can see where the wireless charging pad has a spot where it contacts two pins on the phone side. I bent those two small pins slightly upward and put the back back on. YouTube how to get the back off I only used a small pry tool and my fingernail to bend the pins. You don't need to unhook the back. You can do everything with it connected.
Go slow be careful Good luck
Hi, I don't really know how to describe my problem but I'll try my best...
My Mi 9 shuts down from time to time and I can not simply reboot it but have to wait until it miraculously recovers. I had my battery replaced a few months ago and thought it could cause my problems, therefor I opened up phone my phone to get some information on what the problem is. First of all I noticed that some screws where loose, I checked the battery connector but that seems to be alright so I put everything back where it belongs and made sure all screws are thightend up. Now my phone boots up and I can use it as usual but it still shuts down from time to time without any interaction. I also noticed that I can bring it back to life if I put pressure on the 2 screws with the warranty indicators. Yesterday I deactivated the haptic feedback to see if the vibrations somehow kill the electric circuit or something like that. So far 24h past without any outage!
I found a few old threads (like this one) with somehow similar issues but couldnt really find a solution. Most said it is a battery issue but I'm sure it is not (bought a new one + I also tested it with the old original battery). Any suggestions would be much appreciated or maybe if you have this problem with your Mi 9 you could try the things I stated above (in case your phone dies & you need to bring it back to life to backup your data)
Yea, so you'll need component level hardware repair to take care of that, possible short circuit
