vox - turns itself off with no reason ;/

hi,
as you can see, I've got quite unusual problem with my vox.
the phone screen goes black, it blinks once the right green diode for half a second (could this be an error code?) and turns itself off. (not saving any changes made, or sms sent/recieved)
it usually happens when I make a phonecall, or browse the net, but lately it has started to happen randomly, when I browse the menu, or use any other programs.
What's interesting, is that after turning the phone back on form such a malfunction, the battery status shows it's below 20% and turns itself off again almost instantly.
The only solution I've found so far, is to wait some time, switch it on again, and pray that the battery indicator would show the state before malfunctionong. If it does, the phone could work as long as the battery remains charged (or turn itself off again, as it happens more frequently lately)
Does anybody hav some clue what could it be? malfunction of the battery, or phone itself?
I dont think it's a software issue, because just yesterday I replaced WM6.1 (drGonzo) with wm 6.5 ( the 2.1 ver by frauhottelmann)
and it still occusrs.

Same problem
Yeah i am also facing the same problem with my Vox...it is around 1.5 yrs old...and i know its battery is dying...but it happens even the battery is fully charged...
Is it really because of the battery or some hardware...

Dude its due to battery .May be you are charging your machine through USB. Your battery need replacement..It will show you full battery.Its false showy.
I faced the same.Now I happy after changing my batttery

FIrst of all check the battery mates.
Me and my friend both had the vox that with full battery charged suddenly turned off after a call...and definitely was THE BATTERY.
Now I bought a double capacity for about 10 euros shipped...and my vox stays on without intensive usage (3-4 calls of 4 min each, and about 10-15 sms for about 8 (EIGHT) days)

Try to empty the battery completely and then recharge it completely!
To really empty it, put it in boot loader and unplug the cable. Let it sit until the screen turns off. Then recharge it without turning the device on.

My phone has started doing this recently, it doesnt seem to be as bad if I put it on Aircraft mode, but it always turns off randomly after a while at least, I am going to try frauhottelmann idea now.
Also, if it works I would like to flash it to WM6.5, how can I check to see if I need the USLP? I got the phone second hand so I am not sure what the phone was originally.

Had this problem for a few weeks now. Just put it into boot loader mode to see if it works. Shall let you know later or tomorrow

forgot to update the topic ;D
I've changed the battery for a new one, and now it's running smoothly and lovely

Since i m facing the same problem and that now it is confirmed that it is due to battery, I wished to try FMs idea. but its now more than 2 days in bootloader, my phone is still not discharged completely. is there any other way to completely discharge the battery?

Well, seems your battery has plenty of life! LoL
BTW I suggest you to activate BT and WIFI...then run TCMP into loop and maximum volume...
the phone should run out fast...when the phone suts itself off..you could do the FM's thing just to refine the discharge.

No luck with this method. The problem still persists. It is still turning off randomly.
Guess finally, i'll have to change the battery. hope after changing the battery the problem gets solved.

yap, its the battery alright. facing the same issue, but the battery is warn out due to intensive charging from my car...
so, incoming new battery

actually i think i have a different kind of problem... my mobiles do not restarts instantly, the screen first fades to grey (as if the lcd is damaged with only grey and white vertical lines visible), and then to black and then it restarts. has any one faced similar problems? Can this be solved by changing the battery?
and i dont know but somehow each time i set the correct TIME in the clock, after sometime my clock slows and shows the wrong time(as in case of a wall clock with weak batteries).
any suggestions?

This method worked for me....
Switch off the phone, take out SIM..clean the sim enclosure area and insert SIM..RESTART

An easier way to turn the phone off other than having to remove and rinsert the battery if the power button does not work, is to open the Sim card door.

[Q] Reboot loop and empty battery (brand new opo)

Guys
I'm sorry to have to post another one about reboot loop but I cannot make any sense out of what's posted before me, or at least in my situation. So here you go :
I got my brand new phone 4 days ago
updated to 4.4.4
installed my usual apps (nothing dodgy)
Nothing else. All worked fine
Last night I leave my phone in plane mode and charged at 70%.
This morning ... I press the power button once as usual and find my phone totally discharged
So plug the original charger and...
it goes in non stop reboot loop
(sometimes I see like "battery discharged" in red for a split second)
not taking any charge : I leave it like this for an hour connected to OPO charger but not green LED and same problem
I tried all the power down + power tricks withouth success, probably because the battery is at 0%.
I don't even believe I can achieve anything via a PC console for the exact same reason ...
If nothing else I'll have to file an RMA.
Please let me have your honest opinion...
Thanks in advance for your time and support

Leave it plugged in for an entire day, don't touch it during that time, then try again.

Yeah happened to me too when it got completely discharged. Just leave it for a while and try putting it in recovery so it doesn't vibrate all the time.

I could only manage to stop the reboot loop AND be connected to the charger by hitting (Power + Vol UP). But of course there is nothing on screen.
So I just left it like this since last night and for the whole day today, following the previous advice posted here.
Thanks
PS :I filed a ticket with One Plus AND a claim with Paypal. This is totally abnormal

Have you connected it to a PC yet? See what it shows up as (if anything) in Device Manager.

Hi Timmaaa,
I tried this of course and the opo screen shows a red message for a second: "battery too low (0%) to communicate via USB" or something like this.
Hence my post, actually...

K1 tablet screen turns on randomly

I posted this in the geforce forums as well with no response so I'm trying here. Original post: https://forums.geforce.com/default/topic/903373/k1-tablet-screen-turns-on-randomly
I haven't had this tablet for longer than a week now. When it's charging the screen turns on randomly. There will be no notifications or anything on the screen. It keeps happening when it's charging and i have no idea why. I don' t have a case yet so it has woken me up a few times over the night from lighting up my room whenever the screen turns on.
This doesn't seem like normal behavior to me.. has anyone had this happen to them? Should I be concerned and try to get a new one?

Has anyone fixed the problem?
Thanks

Do you have locked bootloader and a custom ROM installed?

Nope, everything is stock..

Then I don't know man...
The same happens to me with every custom ROM in my locked bootloader tablet. With stock it behaves normal, so I concluded that somehow it has to be something related to bootloader or something.
But re-reading you again, it isnt the same thing. In my case, The whole tablet turns on after being off when charging. Not The screen only. If I were you, I would do a factory reset and would see if it does The same thing with no other apps installed.

I have this happen using both the stock kernel and the BitO kx 060 kernel, but only when charging from my laptop usb. Using ampere to monitor battery charging I notice that my laptop's output fluctuates up and down, sometimes down to zero. For me I'm assuming it turns on when it either stops getting a charge, or resumes charging. I do not have this problem using a wall charger, but i am using a 5v 2a charger. Hope this is of some help pointing you in the right direction.

ooohhh.. that's a good idea. Thanks! I'll have to try another power source when I get home. I'll try that and will update the thread with my findings.

Hey, just thought I'd ask if you ever found a solution to this? It's happening to me, too: brand new, entirely unmodified K1, straight from the shop. While charging, the screen keeps turning on and off, which is not only mildly annoying but probably makes the charging take a lot longer than it needs to.

That's actually normal for Android devices. If the screen is off and you plug the charger in, the screen goes on. Same when you unplug. So that you see/know it's indeed charging. However, you can change the screen Sleep time and Daydream under Display.

if i leave my moga controller connected my screen keeps turning on

Happens to me as well, wild guess for me is there isnt a charging animation for the tablet when it is powered off, if i power mine off the second i plug it in to charge it will light up with a black screen 1st then proceed to normal boot, or sometimes there's a battery charging pic then it boots normally

Phone shutting down at random %ages (50, 60, 40+)

Hi All,
I'm facing a weird issue with my phone from more than 2 months and it has reached a frustrated level now. It used to shut off at levels like 15%, sometimes between 15-25%. But nowadays, it shuts down automatically at 40-60% and that is really unreliable. So, i wanted to check if there are other people facing the same issue or is it only my device. Please share your views, any possible solutions, possible reasons, and if applicable, similar experiences.

thanks for the info, i got my oneplus one back in 2013, hopefully it will not shutdown after a while. i have not found such problem and hope i will not in the future as i want to have the phone for at least 5 years

I had the same issue after I updated to MM and recently after latest update also. I had to do the same thing. Reason behind that was xposed was incompatible. But as I flashed everything. (/system/data too ) now its working fine

thanks so much, bought it after my nexus4 died which im still sad about because its one of my 1st real android phones after having a contract android phone.

As an update, i kept my phone on charge for straight 4-5 hours. and now it shuts down after 20-25%. Definitely an improvement. But still it's a mystery why does it show this bug in the first place.

Umm, how has no one mentioned maybe trying battery calibration!? Seems like a fairly obvious first step here to take before swapping out for a new battery.. Plug the phone in and let it charge entirely. Even at 100% in Settings > Battery it will still show "100% - Charging on AC" (or USB whatever you've got connected)
You need to wait for that to turn into "100% - Charged." Then, calibrate using any battery calibration app from the playstore, ( I use this one )
After it charges to 100% - Charged, hit "calibrate" in the app, disconnect the charger, and let it drain entirely. You might find it dying out before 0% once again, but this hopefully should have been the last time. Plug the phone in and switch it on as soon as you can while it starts to charge. Let it charge uninterruptedly to 100% - Charged, again.
Not saying this might solve it 100% but it is an option to try.

Well already tried and i may sound a bit silly, but studies have proved that battery calibration is a myth. Android automatically cleans the batterystats.bin file after every single full charge. Rest assured, i have already done that with no avail.

I had the same problem, phone was switching off @ 40% and at times @35%. Battery calibration certainly helped. No more problems now. Works well if the phone is rooted.

Poco F2 Pro does not turn on when charging

Hey!
Yesterday I've stumbled upon a very serious (to me) problem, to which I cannot find any solution anywhere - I guess nobody so far reported anything like that.
My phone went out of battery (discharged to 0% and turned off, it was when I really could not plug it to charging).
When I connected it to charging, there was no reaction apart from the red light at the top of the frame, indicating that the phone is charging, but has low battery.
Apart from that, the phone looks like it is dead. It does not respond to anything - cannot be turned on nor enter the recovery/fastboot mode. The screen simply remains black, while the diode located in the pop-up camera lights red. As soon as I disconnect the phone, the red light goes off too.
I've had exactly the same problem once in the past, but then it came back to normal after 2-3 hours of charging with the red light on. Then the light became yellow, indicating the battery is "normal" and the screen regained functionality and the system booted like normal. This time however, it has been charging for over 24 hours and the phone still plays dead and the annoying red light is still there, giving me hope that the phone is not entirely dead.
How can I fix that? Sorry if I'm posting in the wrong subforum, but that's my first time. I only used your custom ROMs and kernels back in 2015-2017, but never posted anything.
Any feedback on the problem will be greatly appreciated!

I take it you tested with another cable and or another charger?
Which rom currently?

thank you for answering!
The charger and cable does not matter, the issue is still there. The phone detects that it is being charged, right now it has been charging for about 25 hours with several breaks for several minutes (I tried turning it on with the charger unplugged).
ROM is the latest official stable MIUI release. On this particular phone I haven't unlocked bootloader or messed with software in any way.

don't bother, send it back to the seller.
.

okay, thank you. I will wait and see if anyone else got any suggestion.

Put some pressure on the right hand top of the phone or try to bend it a little bit on that spot.
When it is charging then, send it back to the reseller under warranty.|
It happened with a few users and they got under warranty a new F2 Pro. (EU).

How long did you press on power on to turn it on? It take less than 5 sec to power on normally.
Once I have to press for long time to turn it on.

I got the same problem just now. Did you discover a fix?
