Phone turns off while on charger. - ZTE Axon 7 Questions & Answers

Anyone have an issue with LOS where the phone freezes after being on the charger for a long period of time? When I plug in my Axon 7 to the charger overnight, the phone freezes (I think). The notification LED is green but the screen wont turn on. I have to long press the power button to get the device to reboot. When it reboots, the phone has full charge. I tried wiping the device (data/cache) and starting over and the problem still occurs. I am on the 4/10 nightly.

I've found this problem on a second Axon 7 running LOS. I don't think it's an issue with LOS since I have a third Axon 7 with LOS and it runs fine.
Any one have any suggestions?
This is the A2017U.

[Q] ZTE Blade (Dell XCD35, unrooted running v2.2) doesn't switch on.

Hi.
I have the Dell XCD35 version of ZTE Blade and I bought it only about 2 months ago. I haven't rooted the device or anything and it still runs v2.2 OS. Today while I was messaging in my phone it suddenly switched off for no reason (there was more than 3/4th battery charge left). I thought it might have been some random issue and tried restarting the phone. But the problem was that the phone now started to reboot on its own after switching it on. Like some sort of loose connection. I removed the battery and SD card and then re-inserted them and tried to switch on the phone and now the phone won't even power on. It is like a total brick now. At times while pressing the power button the backbutton LED red light flashes, and the 'Dell' logo is displayed but it switches off immediately. While plugged in to the charger, the phone reboots continuously on its own without even pressing the power button.
I have no idea how this happened suddenly. The phone was working perfectly alright until the last minute without any signs of faulty device. I'm not a heavy user in terms of games or anything. I searched the forum but couldn't find a similar issue (every reboot-doesn't switch on problems were CM7 or rooted device related).
I'd be really grateful if someone could help me!
Just take it to a Dell service center

Been there done that.
It's probably a virus in the boot. Just take it to a dell service center, they'll fix it up for ya.

Help!! Nexus 10 don´t charge, don´t boot

I´m on Paranoid Android, last version. I was whaching a movie with less than 4% battery, and It powered off. Problem is that It doesn´t boot and It doesn´t charge either.
Please please Help!!!
Sorry for my english
Hopefully your up by now after letting the device charge for a while. If not I'll throw this fix out in case it's a software problem. I have no idea, but: The Nexus 7 has a similar situation of not accepting charge after the battery runs dead. Maybe the same fix will work? With the charger plugged in, hold your power/vol button combo to boot into bootloader/recovery. From there select power off. Then the tablet "should" accept charge. It's the first idea I thought of, but I thought that was an Asus problem.

The problem is that you can´t boot into bootloader/recovery. Tablet doesn´t respond. When charger plugged in, It shows icon of battery when pressing power button but it dissappears in a second....
Hold power button 15-20 seconds until it vibrates & release. If no boot then, unplug and try it. I had this problem once also. Mine finally booted when unplugged for some reason (after being on a wall charger for a couple hours). Someone told me during my ordeal to first plug into a computer for the 1st hour, then go to the wall charger. I think holding until vibrate was the key for me, or so it seemed.

It seems to be charger´s fault. I can confirm it in one hour...
Edit: It was the charger...

Asus Nexus 7 (2012) issue?

Dear XDA,
So I rooted my Asus Nexus 7 back when I got it with cyogenmod back in the day. It stopped working due to it dying and would not charge. So after a miracle and being plugged in for three days it would work. Now when its battery died it would not power on or charge at all. If I plug it in to the charger, my screen shows nothing but I can see the screen backlight so it is doing something. If I try to open the bootloader with the PWR and the volume rockers pressed the screen would flicker but won't show the android mascott with the gear's at all!! I was planning on upgrading to an unoffcial andriod 6.0 rom and run some linux on it. Is my device really dead?
It could be the battery reached its end of life or an I eternal short happened in it. I had a droid 4 that did the exact same thing. The bootloader checks the state of the battery and won't go past initializing the screen if it detects an issue

Phone Just Died

So earlier this week, I was using my phone with Google Maps like usual. I plugged in my vehicle USB port to the phone to save battery. I had +50% on the phone and 1A USB port. So after like 5 minutes of it being plugged in, my phone just turned off. I tried turning it back on and all I get is the boot screen, then AXON shows, and puff... Phone off again. I tried booting into recovery but phone turns off before TWRP finishes loading. Phone doesn't seem to be charging. Tried different cables and charger to charge phone but nothing. No charge light. Seems like battery is dead because the phone turns off during boot and battery not charging.
Nothing seems shorted. Phone been working great for weeks before this. BL unlocked, Debloated stock, TWRP. Any ideas other than sending back for warranty? Luckily I still have my S7 as primary but I had my Axon for primary for my trip for real world daily use. Needles to say, photos and videos are wanted off the phone.

Have you tried going to bootloader mode by holding power and volume down
If the battery has died, then the phone wouldn't turn on is my thinking as everyone you then it on it eats some vattwry
You didn't mention specifically, but have you tried using the factory wall charger & cable and leave charge for like an hour?

Original charger but with certified Micro-b/USB-C cable I've been using for weeks between my S7 and the Axon.
So I left the phone alone for the last few days as I was busy at work and Just didn't feel like messing with it when I got home. I tried to turn the phone on but battery was dead. The quick flash of red led was the indicator trying to power it up. So I used my Samsung charger as it was right there and the original ZTE cable. Phone lights up charging and so I left it as is to go to work. I get home, the green led is lit, so I'm hoping my phone will power up now. Nope, right back to my original issue. Power on phone, gets to Axon logo then eventually turns off or goes black screen. I tried booting into recovery but turns off before fully loading. I try to charge phone again but no led indicator.
So later today, I'm going to try to boot into fastboot and try the new TWRP recovery. Maybe it was enabling r/w on system that caused this. I had downgraded to unlock bootloader and then installed ZADmix. I've been usuing it nonstop for 2 weeks with no issues. I have xposed installed so I know rebooted a few times to get everything working and it never turned off since then.
Really frustrating as that's the phone that had my pictures on it.
Hi @RoninBlackSoul, so what did you end up do ? Have you found any way to bring back the Axon from the dead or sent it back to ZTE for repair / replacement ? Same thing just happened to me, and for me Axon 7 is my primary phone ... if the phone is really dead ... will neve buy another ZTE phone ever !!!

Honestly not sure what did it. After battery drained, plugged it in to charge for 2 or 3 days. Then remembered some note about enabling write access in TWRP (something like that) would cause bootloops. Which is weird, rebooted the phone a few times when it was working.
Any case, I reflahed the recovery/bootstack in EDL and got my phone back. Been working great 5 months now

@RoninBlackSoul, thanks for the feedback.
Got mine working also, my phone was not charging at all. After suddenly rebooting and battery went dead fast, phone was not able to charge for about two days. After which, suddenly started working again, was able to charge and works normally now. This is weird. From my point of view this could be: 1. some sort of auto-protection perhaps or 2. an actual hardware design issue that manifests at random (for some after few weeks or months after purchase). For the 1 point: I was using a non original cable using the original charger, and the USB type c plug was hot at the time the issue occurred. Perhaps due to that heat some protection mechanism manifested that got reset after phone was completely out of juice. Will use only original cable with the Original Fast Charger from now on, as the usb-c plug of the 3rd party cable was fine with a normal charger (non QC3). Hope issue will not manifest again or, Axon 7 will be my last ZTE device ...

I only use good chargers rated for QC or 2/2.4 amps like samsung, anker, aukey. Haven't had issues since. Plus certified type-c cables at all times

Phone Won't Charge

My Essential Phone for some reason yesterday thought the battery was at 100% all day long, no matter how much I used it. I plugged it in and it didn't charge. Now this morning the phone is dead and won't wake up. Any help in getting it started?
What have you already tried?
-another cable?
-another charger?
-another wall outlet for the charger?
-does the notification LED light up when it is plugged in?
-have you plugged it into a computer, to see if it gets detected by the computer?
-> if you have done this and it fails, have you tried other cables? other ports?
Some more info would be helpful.
Are you rooted?

As it turned out, the answer was to hold my power button for 10 seconds to force a reboot. Apparently once the phone had shut off it started charging normally. The software is now reporting battery usage as normal after the reboot. However it's still a strange bug.

I can't even guess how many glitches I've gotten out of That way? That literally would have been the very first thing I tried.
