Battery dies suddenly - root cause? - One (M8) Q&A, Help & Troubleshooting

Hi
I've got my hands on a nice HTC one m8 (16 GB) version. Unfortunately the phone has some kind of an issue. That's why the old owner bought a new phone and gave it to me.
The phone works flawlessly when connected to a charger. You can play games, run benchmarks etc.
As soon as the phone is disconnected from the charger it turns itself off under heavier load. Battery status is around 78% when this happens.
This happened under the latest stock ROM that was available.
Since then I unlocked the bootloader, installed TWRP and could reproduce the same issue with different Custom Roms (current official LineageOS builds, SlimRom, MoKee). Always the same issue.
On one occasion the device reset itself completely when it turned itself off. This would be an absolute no-go if I would like to use the device as a daily driver.
I checked the internet including all possible related threads here on XDA but could not find a solution.
The following recommendations did NOT work:
run self-test ( *#*#3424#*#*) in safe mode -> not possible anymore due to custom ROM
pressing Vol +/- and Power Button for 3 minutes
completely wipe everything (I already did this every time I installed a custom rom)
let the battery drain to 0% and then charge it to 100% and keep on charging for some hours with several restarts of the device
So my questions:
What's the root cause of this issue? Is this a general weakness of this device / model?
Why does the device not recognize the battery status correctly? With any other phone I had (Galaxy S2, Galaxy S3, OnePlus One) I never had the issue of the device turning itself unpredictably off.
Is it worth having the battery replaced? This would cost me about 100$ in local currency. I fear the problem only shifts from "78%" battery to a lower percentage and the device still unpredictably turning itself off. Also the device resetting itself is a bit of sword of Damocles.

I decided to buy a replacement battery from AliExpress:
Since I'm not yet allowed to post links: Search for "HTC One m8 battery".
The product I ordered was from the seller "QCKBST Global Store". The battery is reddisch / orange and includes a tool set in the preview-picture.
As stated in several fixing manuals / manuals for replacing the battery: It is a pain to do this with a HTC one m8!!!
With the proper tools it is feasable though. I also had the bad luck that all my internal wiring was covered in copper tape which made the replacement process not easier.
The replacement battery came with about 56% charge. I then charged it up to 100%. I can currently use the device playing games under heavy load (device gets very hot) down to 2-3% without any issues / sudden power off. Yay!
Pros:
Cheap
Works
Cons:
No battery temperature sensor. Most likely being a non-stock replacement battery
The tools delivered with the battery did not fit. It came with a Torx T4 instead of a T5. No help from the seller. Had to buy a tool set from another seller
I will very likely start using the device as a daily driver for the next few weeks and will post an update about the battery performance.

I did this a few weeks ago. Replacing the battery was a piece of cake Tbh. Not difficult just time consuming.
No damage except some marks to the speaker grills, which I was prepared to sacrifice and replace anyway.
Battery works real well now. Took a few discharge cycles to get it working 100%
Now lasts all day and charges under 2 hours from 0 to 100 using a cheap quick charge 3.0 charger from Ebay and a premium cable(this makes a big difference).
Battery Temperature works fine.
Phone behaves like new again now its running Nougat.

Cameron Sino Extended Battery - Review

Thought I would write a quick review of the extended battery I just bought.
Background
I was rather unhappy with my original battery as were most people! It only lasted me a day and as my job requires me to be out and about a lot, plus to call people often, I thought something more robust would be better. My solution = The Cameron Sino 2600mAH Battery!
Initial Impressions
The battery is twice the size of stock. The battery cover did not close on my phone. Total size isnt too bad. It nearly doubles the phone thickness, but when I come onto the testing section later this is a worthwhile sacrifice.
Cover Fit
The cover didnt fit so I decided to buy a 32gb micro sd card (which works fine), and to super glue the cover on. I figured that using a scalpel I could remove the back (I tested and it works fine) if ever required. Hopefully I wont need to access it ever, or until I upgrade in 18 months and decide to sell it.
Performance
After charging to 100%, running down to 0% 3 times, I have now had the phone on for 5 days and it's current charge level is 10%. As you can see this is awesome. My settings:
Helix Launcher
Wifi On about an hour a day
Light phone calls (around 5 hours)
Light texting - 20 odd a day
3g Off
GPS off
I imagine in real life conditions 3 days moderate use would be obtainable.
Conclusion
Overall I am very very happy with this battery. It really brings this phone into the "worthwhile for daily use" category (it should have been here originally ofcourse). Hopefully will be able to use the standard UI rather than Helix when 2.1 comes out. Damn app power leaks.
Rating: 4/5 (Battery door a poor fit)
Edit: Forgot to mention at £16.99 delivered (amazon.co.uk), you can hardly go wrong!!!
Could you post a pic of your phone now please?
Unfortunately my only camera is my phone...... sorry. Maybe someone else can!?
Wow! I assume you like your phone carrier since it is difficult now to remove the sim card.
Well my carrier (Three) used to be terrible. However they appear to have upgraded their cell towers and I now have full signal most places that my friends dont! So yeah I like my carrier!
Why dont you buy the extra thick covers that are all over ebay so that you dont have to glue anything?
Edit: My bad they arent on ebay, but there is a thread in the accessories forum, I'm sure of it.
theres a couple of posts and reviews in a thread on here already and myself and several others paid just £12.99 free postage from ebay
Yeah I rarely buy off ebay - had a lot of problems with sellers before (might just be my luck ). I saw the other reviews, and just wanted to do my own hehe.
any chance to get a pic of your phone? how it looks with the glued cover?
If i ma not wrong, that battery comes with a cover for X10 right? Are u saying that that cover that they provide does not fit properly?
Mine fits properly. You just have to force the sides of the cover into place and thats it. Battery life is much better than the oem one and has a very noticeable difference.
ordered one from http://www.megacapacity.com/26985.html . Lets see how it goes
Just updating this thread for potential cameron sino battery buyers. I got the package 4 days ago. I removed my stock battery, popped this battery in, used the back cover that was provided by them. The phone became almost twice the depth thanx to the battery.
Then the issues started. Even though the green light used to come on when connected to the mains, the phone never used to start. Initially i thought the charge is low, so left it overnight, but then the next morning i saw tht I still had the same issue. After fidgeting with it for sometime, i noticed that there is a 1(or 0.5) mm gap between the battery and contacts because of which the x10 did not start. I used a thin plastic sheet(amost like a sheet of paper) to hold the battery up against the contact and it worked fine. Right now the problem is that if i shake the phone a bit vigorously, it gets disconnected because of the shorter battery.
But i want to see how the battery lasts so am using it for now. It all boils down to the time i have to wait till next charge. If it really gives around 70% more time (as claimed by many in other forums) i will use it despite the bulkiness and the smaller battery issues. Thanx for reading!!!
so this comes with a case as well for £12.99?

Thanks for this info! I was having the same issue with this battery. I thought I was having a driver issue for extended batteries but after reading your post, I confirmed that it wasnt the case. Fixed the problem but with a different approach.
What I did was I soldered a small amount of lead onto the contacts on the battery (careful enough not to short the contacts) so that it would give better contact on pins of the x10.. I know the process seems a little bit drastic but it works! I can't make the phone shutdown even when I shook the hell out of this phone.

Won't boot unless charging

Hi,
I have the gen 1 Moto 360 and I've used it pretty consistently since I got it shortly after release. I've recently started having a strange problem - if I turn the watch off (the whole thing through Settings, not the screen), it won't boot. It'll go through the Motorola "M" screen and then start on the Android Wear boot animation, but always crashes there. The screen turns off suddenly without any visible glitches or errors. I can do this all day long and it always crashes in the boot animation, though not always at the same time in it. On the other hand, if I place it in the charger (regardless of how much charge the battery has), it will automatically start booting and will make it all the way through no problem. I've tried booting through Recovery and even doing a Factory Reset but nothing seems to work other than putting it on the charger (which isn't terribly conventient unless I'm at home).
Based on some of the other threads I'm seeing this is probably a fairly minor problem (fairly easy to just not turn the watch off), but does anyone have any ideas on how to fix it (or even why putting it in the charger makes it work)?
Thanks!
Same problem being discussed here : http://forum.xda-developers.com/moto-360/help/frustrated-360-off-randomly-t3198154
this exact problem occurred with my first moto360. moto replaced it as though it were still under warranty. the replacement watch is now starting to do the same thing. looks like it is just due to battery age, like their hardware that is designed to prevent it from turning on with a "low" battery is reading it wrong. Android Wear is just unstable enough so that some days Wear doesn't respond and eventually ends with a reboot which means OFF until back at charger, even with 80-90% battery!
i had this exact problem. it was a dodgy battery, i opened the watch up and replaced the battery. Since then it has been good
Finding a good quality WX30 battery in August 2018
Are you able to share where you sourced a 'good' WX30 battery from?
I've been happy with my Moto 360 Gen 1 for exactly 2 years, until a couple of weeks ago when all the classic battery problems started (random shutdowns after a couple of hours, still 70% left, slightly bulging back). I've succeeded in learning how to get out the 4 clips, disassemble and reassemble the body, kudos = search for YouTube 'easy Moto 360 batery replacement video'.
Unless anyone has any good tips, I'm about to play the eBay battery lottery. Motorola has confirmed to me that they do not sell the batteries separately. Typical.

I have literally changed mine this morning... So far so good, no random dying at 70%+ and I ordered this one... https://www.ebay.co.uk/itm/163139641091
I doubt its genuine. its is 330mAh not 300mAh and is from a different manufacturer, however, its worth a tenner to see what happens! Also, how easy is the dissassembly fromt hat video, I watched the exact same one. was in peices in 10 minutes and back together quicker!

Battery drops from 50% to 0%

Hi
My Z1C is 2,5 years old. I had a custom rom with locked bootloader. About a month ago it started to drop the battery capacity very fast. Today I wanted to speed up the drain and it took 8 minutes of GTA:SA to drop the battery from 65% to 0%. It was dropping slowly from 65% to 50%, then fast to 38% and it shut off at 38%. Then it has completely no power, when I tried to power it on only red led blinks. In normal usage it can drop from 50% to 0% in a half of hour, even when I just check the time.
Xperia Companion repair didn't solve the problem.
Reflash the custom rom and check if this dont work then battery damaged u need to buy new one. Coz battery after 2years of use loses its capacity.
I reflashed it and didn't work. Now I'm using stock rom flashed by Xperia Companion for a week and it also didn't solve the problem. AccuBattery shows that the estimated battery capacity is just 756mAh after a 0-100% charging. I think I will try replacing the battery, hope it will solve the problem, otherwise I will have to throw a fully working and still almost as new looking phone 0_o
I too had Same problem just like yours... Replacing With New battery helped me. But make sure battery is Genuine.
Now I see that the plastic frame is deformed because the the battery has grown up a bit. I can easily put my nail between this plastic frame and the aluminium frame ;d
So I need to buy a new battery, plastic frame, back cover, USB cover, bottom speaker cover and a back protector film. I hope it's worth it.
If the back cover and the other things you mentioned are not damaged you shouldn't buy them.
I had the same problem, buy a new battery and a back cover sticker, with 15€ you will revive your z1c
Notice also that the phone is old, buying things worth 50€ is not a good deal
I bought it all for about 19€. A back cover with a sticker was same price as a sticker only so I bought it
Hey everybody,
I´m new here but read some very heplful post before. So now I have a real issue with my device, same like you.
My Z1c turns off when 50% of battery is used. It mean I can use my phone from 100% to 50% and then it drops to 0% or from 65% to 15% and then 0%...
I read the linked articel from androidpit.com here on xda about battery calibration and I wanted to ty it soon. I relly hope that will fix my problem...
But I´ve noticed something different too.
I dont know if you have the same issue or not but maybe some of you can help me.
I´ve noticed that when I open file commander app and tap on internal storage there are no folders... it says it´s emtpy, no foldes nor files, that´s a little bit weired I think.
And seconde thing I´ve noticed.
When I look up the storage usage in settings, android is calculating App, pictures, audio, downloads, cache data and also misc. but when its finished the misc. section isn´t there anymore I wonder if its normal or not.
In my opinion it´s not usual that the misc. section disappears.
I hope someone can help me with my issues and give me some advice to fix them.
Thanks for your help and I apologize for my bad english...

Hi
I tried one full discharge and then a full charge when the device was powered off and it didn't work. I bought the parts from aliexpress and a local shopping website so I will get them all in a month, then I will replace them, do some tests and post the results here.
About the files, you can try another file manager or clear file commander's data. I use the MK Explorer.
Next question, you just don't have any misc files, but the system has to search them so it appears at the beginnging. If you remove all files from the download folder, it will disappear too
I calibrated the battery and it shuts off at 0% properly, but its capacity is still 700mAh
The battery I bought turned out to be 14W10, so it's older than the original one... And it is complete garbage with 100mAh capacity (power off at 95%, lol).
I need another one.
Is it possible to get a genuine battery produced in 2015+?
I found these 17W, are they fake?

I bought mine 4 weeks ago on amazon. But I am not not sure if you can buy there: https://www.amazon.de/gp/product/B01MZ8RSCK/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
It is 2500mAh, I don't want my phone to explode
This is only the battery capacity I think. Yes, I was wondering also because the original has 2300. But for me it is working now.
Hi again,
I bought a new battery, maybe it's genuine, maybe not, I'll never be sure. It looks legit anyway. It came without NFC sticker and it was produced in the half of this year. It is running well from the beginning, it took me almost two hours of playing GTA:SA on max settings with 100% brightness and GPS turned on to drop the factory loaded 43% The first result of time with regular usage is shown in the screenshot (stock rom):

Looks good Hope my Z1C would work fine for another year or two

So your mobile got a second life.
Downgrading to a 4.4.4 Cyanogen Rom cured this for me permanently. Still I am trying to find a 5.x or better Rom which has no battery issues...
Hey @jho55, does it still work fine for you?
My phone now needs definitely a new battery.
It turn off at 95%...
@tau45 which battery have you bought?
When I replace it, do I need to flash the Rom again?

Because I could collect it in my city and check it. I had to stick the NFC sticker to this but it was no problem.
You don't need to reflash the ROM

It is still working for me. I also bought the following. Especially the toolkit really helps:
tools: https://www.amazon.de/wortek-Univer...coding=UTF8&psc=1&refRID=WFD1G0EEM8P9XZS014SX
glue: https://www.amazon.de/Dichtung-Akku...coding=UTF8&psc=1&refRID=WFD1G0EEM8P9XZS014SX
You do not need to flash anything again. If you use NFC, you need to add the antenna on the new battery. I am not using it and I will never do, so I just kept it on the old battery.

Loss of digitizer responce

I'm not sure where to post this but here we go.
I've been replacing phone batteries for a while now, more of a side project for extra income. I also do board level repairs thought 90% of that is computer related.
So the oddity I have stumbled upon is that after replacing the battery on a HTC One M8, of which I have done quite a few of, the digitizer became unresponsive.
First thought was of course that the ribbon cable wasn't seated properly however it was. In fact everything checked out fine.
I removed the new battery and re-installed the original one and the digitizer returned to normal.
I repeated this three additional times, twice with two older batteries left over from previous jobs plus the phones original battery and the new battery. Each time the digitizer would become unresponsive with the new battery installed and then return to normal when the older batteries where installed.
The battery is the last one of my "New" stock that I purchased just a couple of months ago and none of them have given me any trouble.
This is the first time I have encountered any sort of trouble with a simple battery replacement.
How could a battery be the rout of the problem?
I have placed an order for a new stock of M8 batteries, though I expect the number of replacements to drop significantly, from the same supplier and will be returning this one. They are OEM and as I stated this is the first one that has any sort of problem.
Any idea's? I won't be sending the new one back for a couple of weeks so I have it at my disposal to test. My next step is to try it out on my own phone as it has been close to two years since I replaced it's battery.
Just to add on to the mystery, I installed the new battery into my own phone last night, same thing happened. I left the battery in place and plugged in my old one without any change, digitizer was still not responsive.
I re-installed my old battery and it functioned fine and then connected the new battery while the old one was still installed and the phone functioned fine.
So something is missing with the new battery that is causing the problem. I also noted last night the the physical size of the new battery is slightly smaller.
In any case the company is sending a replacement and it is the only one out of the 12 that I had purchased that has given me any trouble.
Now I really want to know what else is tucked in with the battery that could cause this.
The battery may not be giving enough voltage to power the device hence the problem arises. It's an obviously defective battery. Get it replaced

I would concur with that if it wasn't for the fact that if I leave the original battery in place and connect the new one to the motherboard the phone operates properly.
I'm 100% sure it is the fault of the new battery, just wondering why it would cause the problem when it is physically installed.
The other point is if anyone else comes across this problem I'm just making them aware that it is something to look at instead of thinking it is the connection or damaged digitizer.

Reliable battery replacement?

Has anyone found a reliable battery replacement? I haven't been able to find an authentic Samsung T8220e battery.. and the third party ones I've tried won't put out enough current (if I turn the brightness up, the tablet immediately shuts off). All the listings I've found so far on Amazon are 3rd party junk batteries.
I just bought a used p600 with a piece of junk Marval Power battery that only charged to 60%. I replaced it with a used OEM battery (at the time, there was only one shop on eBay selling used batteries) and it's working fine. I haven't used any apps to measure battery health yet, but it seems to be performing pretty equally to the three other p600s I've had over the last few years. It's probably up to luck, too (based on the condition of the tablet that the used battery was pulled from).
Hope this helps!
I just ordered a battery from mister-phone on eBay, instead of the pos replacement battery I have been using for a week, I hope the new one is original as advertised
please let us know how the mister phone battery works out. i have to get another battery after actually having some good luck for a while on an ebay purchase. but one side is swollen again and the battery is all over the place. thanks
So far it seems to be the real deal, it have the same markings and shape on the frame as the original, I'm still testing it, and it's way better than the cheap one.
I bought this one on amazon, and it appears to be working. My stress test is to play a game on full screen brightness and it instantly dies with the other lousy batteries. So far, so good... but it's oos. I would recommend buying a battery on amzon though for the easy returns if it doesn't work. Also, a kit with a decent spudger. I bought this one on Amazon that has a pretty good metal one with a decent selection of mini drivers.
I ended up buying one. Battery seems to work well except I can't get it to charge passed 80 or so no matter how long I leave it plugged in for. Other than that it works well. Restarts don't do anything. Anyone e have any ideas to reset the stats or something. I am at a loss. Thanks.
Stock or custom rom?
It's been a while since you posted this, but I just recently had to replace the battery in my SM-P600 when the original battery started puffing up. The only symptom was that home button was jiggly and loose, and I thought that the housing for that button was broken or something, and was looking into replacing the parts associated with that button when I pressed on the casing on either side of the button and everything clicked back into place and the button worked properly. I then noticed the screen was slightly bulging int he middle and realized it was the battery expanding.
Anyway, the assortment still available on Amazon has pretty bad reviews, so I gambled on a new listing that didn't have any reviews except the seller has been around for a while and is reviewed very well. Received the battery, replaced it, it took a while to charge up, but it holds a charge well and stress tests (full brightness with a taxing game) fine as well. I'm happy with it. Keeps my tablet alive for a little while longer (even though I don't use it much anymore since I got my 15" Chromebook that converts into a tablet).

Incidentally, I also bought the same toolkit you mentioned and it's a really good one. I've used it disassemble four different devices now and it's worked well. Good toolkit for the price.
