The problem with my ZUK Z1 is that I' cant keep the phone on for even 10 seconds, as soon as I plug the charger in it starts looping, I tried to go into the recovery but the problem is that is does boot in the recovery but again reboots and hence starts looping, I haven't found any solution regarding this, the phone only stays shut if the battery is drained or removed, as soon as I connect the battery the loop starts again.
Can anyone help me with this issue? If there is already a solution posted share the link.
Thank you.

There are several discussions within the Q&A section where your question belongs to https://forum.xda-developers.com/zuk-z1/help/zuk-z1-bootloop-t3881113
Just have a look there
I will try giving my 5 cents here, but please NOTE that im not an expert or even technician.
Like a month ago i got Zuk Z1 for free. It was completely dead unless connected to charger/usb and it would immediately start bootloop as you connect it. In short, it was battery in my case, and to be even more precise it was loose contact on a battery itself (manufacturer defect or just some stupid technician that damaged battery).
Also note that on these phone in order to see charging screen it first has to boot with Zuk logo and only then display charging screen. So if you have same symptoms on your phone it may be worth it to check battery.

Hello guys, this is my first time posting up in XDA and I am encountering a very weird problem with my N4
Disclaimer, the following is a long write but please bear with me and give a read.
Here's my problem after flashing the simple asop 29/5 build for mako. I come from same rom build 21/5 but i did a clean flash for the latest build. As soon as success flashing the latest build with gapps, then as usual will proceed reboot the system. Just right before the boot animation, the phone immediately went dead. I am sure that the phone is still left with 50%+ of battery at the moment.
Anyhow, I decided to plug it into charger. And voila, the phone now able to go through the boot animation and everything just fine. After setting up and restoring backups, I unplugged the charger, its 75%+ on the battery. Within 10-15 seconds, the phone immediately go dead again. I hit the power button and tried to boot up. Again, right after the Google logo screen, the phone went dead.
Commonly this indicate a problem with the battery. Yeah, but I went into recovery twrp and disabled the screen timeout & max the brightness. Guess what, surprisingly it lasted more than an hour which proves that this wasn't battery fault.
What had I tried so far, is just switched off the phone and plugged into charge for 2 hours. And obviously it doesnt solve the problem. I am backing up all the data at the moment and plans to drain the battery all the way down just leaving it screen on at recovery.
Anyone who know what happening with my n4 or encounter similar experience, please feel free to share the solution. Many thanks

Have you tried making a clean wipe and trying either stock or another ROM, to see if it works then?
Your test doesn't prove it's not the battery's fault. Flash back to stock, see if the problem persists and if it does then you know you have a hardware problem. Could be the battery.

Hello, much appreciate your reply. I flashed back to stock 5.1.1 now and yet this problem is still persisting. Thus pretty obvious thats an hardware faulty.
In another forum, a guy with Nexus 7 had similar situation as me, and he suggests that its the battery or the circuit board at the charging port went kaput.
Guess nothing else I could do right now, gonna send in the phone for repair and hope the bill wont cost as much as a used nexus 4
Hi,
I have a problem with my Find 5: I am stuck in a bootloop. The Oppo logo appears and after only a few seconds disappears, the phone vibrates and then the logo appears again. And this goes on and on.
I can get into recovery and fastboot but the real problem ist that my Find 5 will turn of again after maybe one minute into recovery. I tried it with CWM and TWRP. When I want to turn on the phone or get into recovery without being charged, nothing happens.
Before that I haven’t used the Find 5 because the USB-Port was broken and it would not charge. Even if the phone had a connection, its battery percentage would not increase at all. Then I ordered a new battery and a new USB-Port. I installed the new parts and suddenly the phone started to work again. I flashed a new nightly of CM 12 and installed some apps. The next day (it was charging over night) I unplugged the phone at 30%.
When I looked at the battery chart, I could see that the battery percentage did not decrease and also not increase while plugged into the charger. Then after some normal use, the battery percentage jumped from 14% directly to 0% and the phone turned off a few seconds later. When I charged it, it was stuck in a bootloop again. First it took about 30 seconds between the reboots and after the Oppo logo disappeared I could see that it i charging but after some minutes the reboots got faster (every 8 or 9 seconds).
So I am having the same problems with the new parts again but I don’t know why because it worked for some time…
It seems that the battery is broken again but how can it be? It was a brand new battery and it worked for one nearly full charge. Are there some common mistakes when replacing the battery that I could have made to cause my problem? I don’t know what to do and I want to try everything that is possible before getting a new phone.
Edit: Now I know where the problem is (or where it is not) but I have no idea what to do against it. The problem lies somewhere in the mainboard. Because when the charger is plugged in the phone will start to reboot again and again so the cable between USB-port and mainboard should be ok. But the battery is not charging. The phone worked with the new battery for a while because it was already charged when I built it in. And now since the battery is empty again I am experiencing the same problem as before again.
So does anyone have an idea? Where is the exact problem and can I fix it without spending much money on it?
Thanks for your help

Let me explain what happened: I was using the phone as normal, but suddenly it started to reboot itself, and with every reboot it was losing some battery until the point it lost all the energy, and now when I try to charge it, the only thing I get is the battery animation starting and suddenly disappearing, like a bootloop. Same situation when I try to boot into Safe Mode or Recovery Mode. But I was able to boot into download mode, so I tried to flash the stock firmware again both through Smart Switch and ODIN, but I got the same results. And also, this only happens if I have the phone connected to the PC or the charger. If I try to turn it on while disconnected, it doesn't do anything. What can I do???
Update: Well, now it reaches the Samsung logo but it get stuck in a bootloop. I 'm also able to boot to the recovery, but I'm not really sure of what can I do from there
I'm having similar issues!
Upon further investigation, I discovered some pocket lint stuffed in the bottom of the MicroUSB-port. A toothpick was enough to get it out. Still having issues with "mmc_read" failure, booting and long response times, but at least it charges reliably now. Will flash updated recovery/kernel/ROM as it has been a while - fingers crossed this will help.
I'm thinking the root cause of our issues might be different, but check your USB-port if you haven't already.
For my next phone I will consider integrated port covers, like the Xperia series.
I bid you good luck fixing your problem. Would'nt mind knowing what the root cause of your problem is if you find out.
The phone is alive again! The problem was the battery, I just replaced it and the phone booted as normal

Thanks for the update. Just out of curiosity. Was the bad battery a little bit puffy. On my note 3 I could tell by feeling and looking at it from the edge. Battery going bad starts to Puff up in the middle.
Hi all,
The weirdest thing happen to my 1,5y old lavender (with official LOS 17.1 on it)
Out of the blue, it started powering off and rebooting, only to run for a couple of seconds and then power off again.
Booting to recovery (TWRP 3.4.0.0) gets to the splashscreen and then power off again. Same thing for Fastboot so no flash of any rom can be done. A couple of times I managed to make it boot "almost" completely but then again power off.
I'm now letting it battery drain to see if there's some progress from there.
Did anybody ever encounter something like this?
I saw this thread https://forum.xda-developers.com/redmi-note-7/help/help-phone-rebooting-t4098107 but not progress has been reported.
Thanks a lot in advance.
UPDATE: I left the device to drain all remaining juice until it could no longer power up. Then I charged it again and the issue disappeared. I don't know whether this is gone for good but I hope this may help others.

Maybe battery... Try to keep the charger connected... If boot with charger connected, it's battery fault.
I had similar problem few years ago with an old Samsung S3 Neo, but on that case was easy to replace the battery.

it happened to me too , i thought it was a software issue just to find out that it was a power button problem . it got stuck even though it is still clicky
So here the deal guys , my mi 9t pro is about a 18 months old and recently started to have issues with battery life (long story and since I wasn't personally using it I can't explain the issues very clearly but it was all over the place doesn't charge at times verified the charger was indeed charging another phone , sometimes the phone turn off when the charger is connected so quite a lot of erratic faults and no consistent issue to point out )
I have been trying to look into it for a week now and this is my observations.
So first and foremost the phones does not turn on ,meaning that when just the power button is pressed it is stuck on the boot screen with just mi displayed on the screens and does not change at all even after hours.
I did find a way around it when I send the phone to recovery mode by pressing the volume+ and the power button and then selecting reboot and reboot to system. This way the phone always turns on . How long it remains on is a different matter some times it a few secs while at other times it could up to 10 mins and most of the time if its plugged to a charger and I disconnect the charger it immediately turns off.
Things that I have tried
Firstly, I had suspected the battery but on opening the rear cover realized that the previous battery looks in extremely good shape additionally I connected the new battery but connect the cable and realised that the fault persisted.
Thinking it was a software issue I also tried to flash the latest MIUI version from its official website with no help.
Now I am certain the issue is with the circuit or with the motherboard.
Any previous experiences and how it was fixed could be helpful .I don't mind doing some troubleshooting myself and can arrange for advance tools if required.
In short would appreciate advance level help as I enjoy fixing these things myself.
TL;Dr my phone is behaving quite erratically and having tried the battery and software need help repairing it.
