Zuk Z2 turning off while charging - Lenovo ZUK Z2 (Plus) Questions & Answers

Hi,
My zuk z2 has been having an odd problem in the past month.
When charging overnight, from what i can see as soon as it hits 100%, it turns off. It stays off for multiple hours, then turns back on, having used 15% of my battery and will not continue charging. This has happened over multiple roms, all clean flashed, and as the most recent one was just after a clean flash of a new rom i had not set up any app, only downloaded them, it would not be that. i can only think it would be a hardware defect.
if you guys have any answers to why this is happening, whether i should take it to support (out of warranty), help would be greatly appreciated.
Thanks.
Last nights battery history if i can figure out pictures

Desire won't boot flashing amber and green led

I have searched here and google all day to no avail. After charging my phone last night I tried to turn it on this morning and just get the amber led light then the green. It just won't boot. I have removed the battery several times, checked the battery contacts, all fine. I have tried the volume and power button trick but nothing. I rooted the phone about 4 months ago to gingervillian. All, has been well until now.I left the battery in there for a while and noticed that it got quite hot. I have now removed it and am going to leave it out overnight to see if it is anything to do with overheating. Anyone ever had similar or heard of this before, help appreciated.
Flashing amber usually means the battery is completely dead. Maybe try a new battery because it might be dead.
Oh, I like the sound of that planning to go to Tmobile shop (nearest one to me as on their network) to get it checked tommorrow. Thanks for that info.
Just an update for anyone who may have the same problem. I left the battery out all night, came down this morning and tried it and still the same amber to green and so on. Left the battery in and then about half an hour later just about to go out and noticed not flashing anymore. Tried it and it booted up fine! Battery only says 46% left will see what happens when I charge it tonight.
Tempted to go back to original rom in case this goes wrong again, didn't fancy telling the guys in the shop that I had rooted it and so voiding my warranty. Although I can't remeber what the warranty length was anyway?
Going to have a think about it as I really can't stand the original rom version.

[Q] Z1c issue

Hello everyone. newbie here.
My sony Z1c seems to have developed a bug/issue. 2 days ago my phone was on charge, green led at the top was on and my battery showed at 100%. I unplugged the device jumped into bed, set my alarms as usual. I then woke up 2 hours later then i should of to find my z1c was dead. Nothing was running in the background etc so instantly knew something was up. Tried charging my phone at work via usb>pc and it kept saying my phone is losing charge quicker then its charging (never seen this message before) . I could turn the phone on but the battery level stayed at 2%, as soon as it was unplugged from the pc it would instantly die.
When i got home i done a few "reset" searches and come across the hold volume up and power at the same time until phone vibrates method. This now seems to allow my phone to charge normally again and the battery goes past 2%. However again today my phone went dead overnight. So the issue is still there, im just able to charge the device again.
I dont appear to have anything running in the background
havent done any firmware,software,app updates in the last couple of days (again that im aware off, unless they forced any)
also noticed the phone gets extremely hot at periods for unknown reasons?
Anyone here able to help or advice? is this a faulty battery, software,firmware issue etc? any fixes

running 4.4.4
14.4.a.0.108
Thanks in advance
Have you tried a different charger? Charge it using wall charger with supplied cable. I don't think firmware is draining your battery. Possible that u r caught up with a faulty battery if u don't have any issues with charger.
My advice "Head to Sony Service Centre asap".
Have you 'ever' installed any custom ROM on this phone then reflashed/restored something later after accquired? It could be the underlying system's battery state is different than the current running OS' one. Try calibrating the battery a couple of times to see if that make any difference.
Hello. Thank you for the replies.
The phone charges correctly via mains and usb(laptop,ps4 etc) since i done that power+volume up reset. Pretty sure my leads and plug are fine. i could try different usb leads though. the charge level is certainly showing me 100% charge
I have never used any ROM's or Roots. i dont know fully what they are. I used to have a jailbroken iphone so it sounds similar. Id be prepared to do down any of them routes if it fixes my phone
Everything updated has been official releases. I dont appear to of updated anything recently though so i cant put it down to a system update or new app update. - something might have glitched somewhere i dunno
Charged the phone during my first post and again it says its gone to 100% after a couple of hours. unplugged the charger. restarted the phone and checked nothing that hasnt been on for the last 3 months hasnt turnt on and all seems fine there. So just left it in standby
checked it 10minutes later to see charge levels. am down to 87%
using gsm battery app it says 68.9% app usage, when i click that
android system 53%
kernel (andoid os) 19.5%
then i have a list of other stuff running all be 2%
them 2 shouldnt be that high should they?
then when i go default settings>power> batt usage
android system 37%
googleplay service 21% (doesnt appear to be updating/syncing anything. should all be off. never used syncing)
screen 14%
android OS 5%
cell standby 5%
the rest of the list are 2's and 1's
phone was cool when charging, since rebooting the device and unplugging it, its now getting hot??? would of expected it to be the other way around!!!
Might want to give it a go of this:

Sorry, newbie can't post URL yet:crying:
Hi again, Jcw i done a full factory result and everything now appears to be fine now. Phone has been on for 3hours standby and on 98% battery, It would have been dead by now and extremely hot at the back. Now running alot cooler. Thanks for the advice.
Have no idea what happened. Something was seriously draining the battery though. Glad its fixed. Thanks again

Phone rendered unusable

So for the last few months, my phone would randomly restart itself around once or twice a month. I didn't really care since it was a minor annoyance. Usually it would be when I was trying to do a bunch of things at once so I figured it might be a software problem. However, over the last two weeks or so, it has gotten worse. I usually charge my phone in the morning for about an hour while I get ready for the day. So by the time I leave the house, my phone is at 100%. What'll happen is I'll unplug it from the charger then will get about ten/fifteen minutes of uninterrupted usage before the screen goes black and the LG logo comes on. And the phone turns back on with less battery. Then, as I go to put in my knock code, it crashes again. Turns back on. Now with even less battery. This continues about five or six times until I'm left with anything from 3-15%. I can't make calls without the phone turning off, can't take pictures. Can't really do anything. However, there are no problems when the phone is charging. I can use it fine during that. I'm almost positive this is an issue with the battery (going to order a new one soon), however I just wanted to see if anyone else had this problem too and found a fix?

had this same problem many times. For me it's the battery. The battery really sucks on this phone.

Horrible Battery Performance After Installing ROMS and ROOTING

Just as it says in the title i am experiencing horrible battery performance on my HTC ONE (M8) ever since i rooted and custom rommed my phone along with other small bugs i noticed. I am currently running the latest DIRTY UNICORNS for the android 6.0 update. Though this was not my first ROM used. Not i will get out of the way that my charging port is very poor quality due to being abused for a while. (Laying in bed with the charging cable and port recieving light pressure while i browse pictures for hours on end.) Anyways. I was charging my phone it being at 34% yesterday and i made sure not to touch it and the little charging light was on indicating charge the entire time while the phone was TURNED OFF. Now at this time I had finished trying out a dozen different roms and was full charging the phone. When i picked up the device about an hour and a half later expecting a full charge it you wont believe me. The phone displayed 17% and was still charging. I was shocked. I figured it was some fluke and left it to charge more. After all i'd installed roms and maybe it'd affected the % reading. I went to pick it up later and the phone was fully dead. but the indicator said 0% and was charging. Now i knew 2 days ago my battery was pristine before rooting my device and before trying out roms. Is it possible i tried a dirty rom that hijacked my phone while it was "Off" ? I have no clue. I know my battery was pristine because on a 1.5A plug my phone would 0-100 in under 2 hours. This is the most of the information i have for you. Again i have no idea what's causing this issue.
Another issue i am having is since i rooted and tried custom roms my LED light on the front of my phone got IIIINNNNCCRREEEdibly dim. It has to be pitch black for you to even see the glow from it. Along with the issue stated above my phone cant seem to charge more than about 35%~ and it takes so long per % i swear i could leave it plugged in WHILE TURNED OFF and it would never reach 100% until the day i keel over and die. Note all battery tests were while the phone was off. Whenever i turn the phone on the % is always different from the on screen while off. (it use to be the same, maybe the ROM messes with that?) Any advice or assistance is greatly appreciated. I already am saving up for maintenance on the charging port.
An additional issue I am facing is the fact even with minimalist android 6.0 my HTC ONE M8 is incredibly slow. As in there is absolutely no apps running or installed with this test. But i tried 1 single game and while on a normal HTC update for 6.0 and the game ran smooth with no lag. So what gives? I thought a minimalist android rom would give my phone a power boost with all the bloatware and applications removed.
I began typing this message at 5:45pm MST my time. It's now 5:55pm MST and my phone managed to go from 0%-2%. Now obviosuly anyone whos owned an HTC ONE M8 on the correct charger this thing really charges so what gives?
Yes i am making sure the ROMS i used were compatible with my HTC being on the carier of AT&T. Any and all assistance in my troubles is greatly greatly appreciated. I really hope you can help me with my issue.
**Edit:: Also my Megabits Per Second on wifi greatly decreased. I on the regular android 6.0 by HTC for AT&T was getting 250-300 Mbps. Now i get 130-180. If there's a comment or fix for this i'd also like to know.
****Secondary Edit: When i installed the A ROM(unknown i tried too many) a while back my phone freaked out on install and the charging animation on the front of my phone went from the normal android 6.0 to the old old HTC charging animation for android 4.4. When the phone goes to display charging it shows that new charging icon with the ghastly red text on bottom from rooting/ROMS(You know what i mean haha) and then it switched to an animation of old. Idk how a rom might have changed this i did not.

Replaced screen and battery, now in (another) bootloop!

Recently I posted about a problem others had as well - when under 50% ish battery, my HTC 10 would randomly reboot, and that would loop until it was plugged in.
Once plugged in and fully rebooted, the battery % reading would vary from where it was before to 1%. Also, certain apps' data or cache would be deleted. I would open, Macrodroid, for example, and it acts like it's the first time being opened after installation.
This has been exhausting, having to constantly be charging, staying above 60% - and even then it still happening. After it does, the apps whose data was cleared varied, and I wouldn't always know until I opened each.
So after this I dropped it and cracked the screen. I have fixed all of my HTCs before with various problems - M8, M7, DNA, Incredible, Max - so I decided to put in a new battery to hopefully fix the bootloop problem.
After watching a few disassembly videos, it seemed best to replace the screen when I opened it for the battery. So I ordered a screen, and waited more, constantly charging, restoring data to apps like Macrodroid and initializing apps all over again.
I finally have the new battery and screen. I have a few hours. I get out all my tools.
A few hours later, I have put it back together. It's like Medusa inside this thing! I was really being risky doing this last night, because I have a ton of work to do today, yet here I am typing this on my backup nexus 5x - so slow!
So the result? Success for the screen replacement, and the battery as well. But, now, it is bootlooping still! I plug it in, and two things:
Plugging it in does not stop the bootloop.
The charging LED does not light up.
So I am hoping someone may have some insight as to what I may not have connected properly. I can post pictures later, I'm not home right now.
I looked and looked and looked and cannot find where I went wrong. I am going to take it apart and put it back together if I can't find the error. Any ideas? Any other places I should post this?
I guess when I get home, assuming it has completely drained itself, I can plug it in, and see if it gets a charge, and if the LED illuminates. I am thinking: charging port is not properly connected back + the new battery did not fix the bootloop / battery issue.
Thoughts?
Bootloops/shutdowns are going to corrupt your data. I would RUU the thing before looking for hardware trouble, which you've likely sorted out by replacing the battery (of course, we're assuming the new battery is good).
BUT before that, is there a memory test in the bootloader or recovery? If so, I would run that very first thing.

Whatever happened to your phone? I have the exact same problem. Infinite boot loop, no illuminated LED, and no way of getting into recovery or anything else with it bootlooping. It occurred after I made the mistake of trying to restart it at 25%. I have the new battery and screen. i'm going to attempt to open this Pandora's box. Seriously going to have to turn my back on HTC. The 10 is so full of software issue problems regarding the batteries that they never bothered to address.
I did the exact same thing a few days ago and my phone won't charge or boot, but I do think the problem is with the button strip, that's what i think, because i tried turning it on before re assembling it and it did turn on successfully and was charging normally but when i re Assemble it, the phone got this problem, now i think when i turned it on before assembling i pressed the power button with a screw driver because i couldn't press it with my fingers, I think there i messed it up, any advice how to fix the button strip and remove a slip nut would be very much appreciated
I had the exact same issue as you(shutting down at 50%), have you found any solution to it?
edit: I THINK clean flashing oreo firmware then latest RUU then twrp then lineage fixed my issue, charging to full rn will drain it over the next day and report back if its gone for good
