Zenfone 2 Restarts when not charging - ZenFone 2 Q&A, Help & Troubleshooting

Hey folks, fiance has a Zenfone 2 that has been flashed with RR.
Out of the blue, the phone started restarting/turning off.
I've wiped it since and reinstalled RR which didn't help.
I've noticed that if I disconnect it from the charger, as soon as the battery level dips below 100% it will either restart or turn off.
I've been unable to find this issue elsewhere. Maybe someone here has an idea?
Thanks!

I had the same problem and don't have Idea of how to fix that.

Phone keeps crashing

When charging, my phone works fine, but when I unplug it, it crashes within a few seconds. If I turn it on without pluging it in first, it boots, and a few seconds after fully booting, it shuts off.
Phone is rooted and I'm using the IceColdSandwich ROM, always on the newest test build.
Help me please, this is really annoying

I have a similar problem - but its imho ROM independent. I left my phone in direct sun for about 30 minutes and the phone was afterwards wery hot and it crashed...
No I can run the phone only, when the charger is plugged in. Without charger attached the phone shut down in 5 - 20 seconds. I think, the extreme temperature demaged the battery. Unfortunetaly Im in Mexico right now and Im unable to buy another battery, to verify my hypothesis.
Its very likely battery related, bacause after every higher energy drain - flash light or similar it crashes even on charger...
Any ideas - suggestions or similar problem? Thx.
check for battery pins bent if they are ok try changing the rom like cyanogen as they are very stable if issue still there replace ur battery with a new one.
had the same...
i had the same problem and when I tried Ascension ICS, never had crashing issue since lastweek....but....it is starting to act weird this morning...not good

Check the health of your battery. There are battery monitoring apps on the market that can do this.
Do you charge using a wall charger or USB port on your PC? The phone cannot run by itself using wall power or USB power and needs the battery to function.
I have a feeling it's the ROM. Can you try a ROM based off an official RUU? Or maybe revert to a stock ROM? Or you could full-wipe your phone and reflash Ice Cold Sandwich.
Hi guys, thx for replies.
In my case its 99% not ROM related - yesterday I tried around 5 custom ROMs (gingerbread and ICS), flashed another recomended radio and RIL and finaly reverted to stock... still the same problem - reboot after several seconds or minutes...
Unfortunetaly Im unable to replace the battery, to see if its battery-related or not.
Regard Pylorus
Problem Solved
After returning back home, I replaced the battery with a new one and the phone works flawlessly again... so voila, problem solved

[Q] Anyone experiencing powering off and troubles switching it back on (charged)?

Hello guys,
I tried to search for a similar issues but I couldn't find anything similar so please bear with me.
My KF sometimes shuts down overnight. In the morning then I have troubles to switching it on again (clicking the power button, holding it for longer periods of time...). It usually helps for the tablet being connected to the charger, but it takes a few tries to turn it on. After I managed to turn it on again, for example yesterday, it had 80% of battery left.
I am using CM nighties and this is happening already for some time.
I am also using juice defender, I am not sure if that is relevant.
Do you have any suggestion, what could be the cause of this? Maybe a suggested alternative rom? Or some logs I can check? I think the powering on troubles bother me more than the shutting off overnight since I always think it won't come back on anymore.
Also, not sure if relevant. If I try to turn it on and it doesn't, sometimes the button flashes orange. After a few tries it turns green and powers on. Not sure if I am now not only confusing times, when it was simply out of juice.
P.S. On a different note, just curious, does anyone know how if there is a rom with working mic already?
Thanks in advance.

Yes, I sometimes have the same issue with the power button - in fact it happened to me this morning where I went from about 60% charge to 16% with a sudden power drop.
Not sure why this happens. I thought it was a bad battery so I changed it but am still getting the problem every now and then.

the only thing that i can think of is that during the middle of the night a soft-reboot happens and it cant boot back up into the system. this would cause it to sit there and continually try to boot up. this would use a lot of cpu and a lot of power. as for why that drains battery while being plugged in, well i cant help you on that.
Thanks for the input. I've wiped dalvik, cache and the system and installed hashcodes AOSP Jelly Bean (http://forum.xda-developers.com/showthread.php?t=2041694) and at least it survived this night without shutting down so maybe this helped. If I come across the same issue, I will update this thread with new info.
Thanks again,

Sounds like a hardware issue, and Amazon has been replacing those of customers who buy new from them.
Mine has this issue too. I KNOW it has battery power, and is still on, but the screen won't turn on. Only solution is to plug in power, then hold down the power button until it shuts down hard. Then turn back on.
I'm returning mine because of it.
Thanks for the info. I am still hoping this is a software issue.Regrettably I am outside o the US and thus replacing it is nearly impossible. I will see, if the issue returns with the new rom and will update the thread if it happens again, just for your information.

Try going to the WiFi settings and selecting 'never' for keeping WiFi on during sleep. This seemed to work for me.... So far it hasn't happened again.

I think this is the bug I am experiencing:
Shutdown bug stalls out the shutdown. Looks like the device is off, but it's still powered draining battery. Currently requires long power button press to fully shutdown after the screen is black (about 15-20 seconds).
from the 3.4 kernel thread (http://forum.xda-developers.com/showthread.php?t=2264563). I am not sure if cm 10.1 nighties contain this kernel, but the description is pretty much spot on.I couldn't test the fix (holding the button for 15-20 seconds), since I already changed roms, but if someone experiences the issue again, he can post if this works and which rom and kernel they are using.
This happens to my Kindle Fire device as well. It just randomly shuts off and it won't come back on until I do a hard shutdown then turn it back on. I currently have AOSP Jelly Bean 4.2.2_r1 on it.

Yes, it happened again to me with the same ROM, but it happens less often. I will try the updated kernel once it is finished.
On May 27, 2013, Hashcode listed the known issues of the current kernel on his website:
Sound / MIC debugging
Deep sleep issues with “omapdss_dpi” device
SmartReflex shutdown loop fix.
Charging driver / OTG improvrments

Note 2 keeps restarting everytime!

Hi guys. A relative asked me if i can repair his note 2. I think his network was locked and the phone keeps restarting everytime. I flashed a new firmware on the phone. The one I use on mine..XXUFNG1, and also I went into recovery and clear data and cache after flashing. But still the phone keeps rebooting everytime. Why is that and how can I fix this?
Note : It's not bootloop or anything. You can switch on the phone, use it for like 5mins and then it freezes and restarts itself. And it goes on like that. Sometimes it doesn't restart also and you can use for more. But most of the time after 5mins, it restarts.

Everything stock..like I said! Before flashing to the newest rom too, everything was stock.
Was the phone dropped or exposed to moisture? Possible battery problem? Reboots even when connected to a charger?

Hi..thanks for reply. I tried another battery in it. The one I use myself. But it still restarts. I don't know if the phone was dropped or anything though. The relative just told me that it needs to be unlocked. Do you think it's software related? Or something is damaged in the phone?
Since it is running a stock ROM and still behaves this way after a factory reset, I think there is a hardware problem.
I might have a similar problem. I copy from another thread:
Hey guys,
I like this rom so far. But since 2 weeks I got an issue.
My phone randomly turns off, atleast I guess that's what happens. Sometimes the "notify" LED is on permanently but the display won't go on. To start the phone again I have to put out the battery and put it back in.
My battery is randomly empty pretty fast even if I just let the phone turned off. This happens like every 5 minutes.
I already bought a new battery but the problem hasn't changed.
What to do now? :>

I like the phone. It's over 5 years old and runs like the first day. Except it DOESN'T wake up anymore after a short time when the screen is off. I can press the power/home button as many times as I want and wait for 5 minutes, screen will still be off. Only way to "wake" it up again is to put the battery out and in again.
Currently I don't have enough money to buy a new phone and I can get a new motherboard for 25$. But I'm not sure if this will fix my problem.
I'm not even sure if this is the ROMs problem since it worked with all earlier versions of this rom perfectly and even the latest release worked for weeks/months.

As long as I leave the screen turned on the display/phone won't go off and I can use it as always. Even the battery don't drop drastically then.
It might be exposed to moisture tho. When I take a hot shower I'll leave it on the window sill and the room gets steamy.
ROM: [7.1.2 r24] LineageOS for N7100 [Unofficial] - Version from 08.10.2017
GAPPS: Open Gapps ARM 7.1 Aroma - 03.05.2017
Baseband: N7100XXUFND3
Ril and other stuff I don't know where to check.
Some years ago I had the SDS and the motherboard was changed without the EMMC bug.
Sometimes my phone only charges in slow mode too.
I try a clean install and newer pico gapps now. Maybe it will solve the problem. I'll reply then if it worked or not.
[EDIT]
Since my phone was low on battery I turned it off completly and put it on the charger. After an hour or so I wanted to look after it.
The green charging light stays on and if I want to turn the phone on nothing happens. The light stays on even after removing the charger.
Seems like a hardware, not a rom problem? Will changing the motherboard fix this?
[EDIT 2]
Quick update. I fully wiped/factory resetted and clean installed newest version of this ROM + newest mini pico GApps. Still the same problem. Gonna try it with another ROM/kernel now and if the problem persists it's a hardware fault.
[EDIT 3]
Fully wiped again and changed ROM+Kernel. Still the same problem.

Friends,
My redmi note 5 pro was 50% battery and it suddenly turned off. After that when power connected no response. Connect via USB and Mi Logo appears first, then the battery icon with a flash symbol in middle. This repeats continuously. Some help, please ?
The phone is not rooted. Still in warranty period. No recent update. The last update was 1 month ago. No glitches after that.

Woh.. its been a long time, though I am still using the same phone. ?
Try a hard reset first, if it doesn't help run to the service center. Don't worry about your data, service technician can easily recover it.
Back then My phone came into contact with sweat moisture and it fried few chips on the mother board.
Fluid damage is not covered under warranty, yet they gave me 50% discount. ?
All the data was restored afterwards and the phone still working fine.?
Hope you will find a solution soon. ?
Hey, it might be a bit late but i found a solution: i charged my phone for a few hours in fastboot mode (volume down + power button). Then turn it off and on again.

I was also facing the similar issue yesterday. Actually my phone fell down while charging after that it's started behaving like that and I kept on charging for 2 hours and tried to switch to fastboot mode still no luck and after that I left the phone idle for sometime witout charging and I gently pressed all the edges of my phone and tried fastboot mode and it's started working.
I know the solution which I gave looks silly but it's worked for me

Phone keeps rebooting randomly without power connection

I'm sorry if this has been asked before, but I couldn't find a definite answer anywhere. So my Lenovo Z2 plus which is rooted and was flashed with Flyme OS. I was playing pubg and halfway through the game, my phone rebooted. I thought maybe my battery drained but I tried to reboot anyway thinking that atleast it will boot up to show 0% battery, but it didn't. After plugging it in, it would work again for sometime then randomly reboot. And when I would reboot it myself, it stops right after the logo.it only moves further if I plug in the charger. So if it's a battery problem, why does it always reboot at that precise moment. And when it reboots randomly, it's not even hot - the screen, the back, anything. Sometimes it works for hours and would suddenly stop, sometimes it works only for a few minute after unplugging. There's no specific app that triggers this. I even changed the ROM to AEX 5.8, and the problem persists. Is it genuinely a battery problem or is it related to bootloader or anything. Because it does not reboot while in twrp. Any help would be appreciated

Okay, so guys - I am using POCO F1, Started having this same issue yesterday, on the internet, I found - this is a hardware issue, and the solution is to get a new battery,
So I went to the Xiaomi Service center, Their engineer said the same, this is a dead battery issue. So I bought a new battery - and the phone is working fine.
so Final Solution = Get New Battery
Original/local - Whatever fits your budget
