Nexus 4 - Nexus 4 Q&A, Help & Troubleshooting

My device fails to remain switched on. After some while it switches off. Sometimes it seems something like turning on wifi toggles it but not sure. I have tried both soft and hard factory reset but still there was no use. It heats up a lot due to continuos loop of on/off. But when I switch it on, it is not completely switched on and somewhat stops in the middle of the process. It turns on only when I connect to a charger but within half an hour It heats up a lot. The battery is not drained when I switch it on. Also when once switched off it does not switch on on its own. So, i feel its not a hardware issue. Can you guide me regarding the problem with my device-LG Google Nexus 4.
My device when on stand by mode works fine but as soon as i start working on it it switches off. Like as soon as i turn my wifi on on handset it switches off. When I try to switch it on it is stuck in the middle of the process and i am unable to switch it on. Later when I connect it through a charger It does get turned on but heats up very quickly in half an hour, I have tried both soft and hard factory reset. When the phone switches on the battery level is same as that before it was switched off. I feel it is not just simply power key issue or power drain issue.

How to charge the titan? opinions?

I've been told that charging the Titan while off is the best way - so the battery resets or something. I don't know if you have to do this everytime or just once and a while.
but i found that I turn my phone off, then while it's charging - it will mysteriously turn itself back on. The battery is not full yet, it just will randomly turn on.
So Is there a way to keep the phone off while charging? (I'm using a wall HTC adapter)
There is no reason to charge with the phone off. Also are you really turning the phone or or putting it in standby.
I hold the power button down till it says 'turn off , yes/no" and I push yes.
by the way what is standby?
push power button to turn phone screen off.
Some winmo phones turn on by itself, the titan and TP are 2.
I use S2U2 to lock the phone so the phone closes itself at a set time.
IMO, turning off your cell phone to charge ruins the point of having a cell phone for the time its off. Even if the phone's off, it'll still be draining a little energy.
Standby:
Phone is on. You press the power button breifly once. Phone screen turns off and phone goes into a low power mode.
Off:
Phone is on. You press and hold the power button and tap Yes when the dialog box asks if you want to turn off the phone. Phone then turns off completely.
If my phone is charging off a PC via USB it will sometimes awake from standby on its own. It doesn't do this when using just a charger. It does not turn on by itself though if fully turned off.
I only turn off my phone to charge if I want it to charge a little bit faster.
Sweet thanks for the replies.
I was just curious. But it turns out that my phone kept turning on, because my charger was on it's way out for some reason.
Tested it and it was only charging at a rate 50mA way less than the 1A label. And it was always super hot. So got a new one, problem solved, glad it didn't fry my phone

what you're referring to is calibrating the battery. to calibrate the battery, you need to charge your phone to 100%, let it die, then charge it to 100% while the phone is off. calibrating your battery resets the sensors inside which provide all the information about your battery, including remaining battery life. definitely a good thing to do every once and a while and you'll notice the difference
There aren't sensors inside the battery.

Phone Randomly Turns Off

My Dash 3G seems to be randomly turning itself off. The battery is full too when it happens. Anybody else having this problem?
I've had this happen a few times too, with the keypad definitely locked.
Any fixes for this?
I had this too, easy but annoying fix:
Turn your phone off, remove MicroSD and turn on, wait untill the phone has fully booted up and then put microsd back in
That should solve your problem
Phone turning off
My Dash 3G has also tunrned off on its own a few times but it was becasue the phone was bumped and the battery lost contact-

Why won't my phone stay off??

I have the Bell version of this phone. I received it last week and I love it so far. The biggest issue that I have with this phone is that it will not stay off.
If I turn the phone off by holding the power button, it shows that it is turning off. 20 seconds later, the LG splash screen shows up and the phone powers back on by itself.
If I run it until the battery dies, I connect it to the charger, and a few seconds later I see the battery indicator. Without fail, within 40 seconds the phone powers back up on its own.
I have done a hard reset, and reinstalled everything and it doesn't help. Is this a quirk of this phone? Is there a fix that anyone knows of? I would really like the phone to remain off when I turn it off.
Sorry to hear you have this problem. I have not experience this problem with my phone.
Mine won't stay off if the power cord is plugged in.
So it can't charge while powered off (this is something I used to do to "re-calibrate" the battery on my Kaiser since WM6.x used to get in the way of the charging).
It could be that your USB port is damaged somehow to make the phone think that the power is plugged in?
That's about all I could think of... I find this behavior really aggravating.

[Q] Nexus 4 shows wrong info about battery

Hello everyone! I will try to explain my problem as briefly as i can. Last Friday i was replacing headphone jack, and before this i put away battery. After replacing i sticked battery back to phone and tried to turn it on, but caught bootloop. I put away battery again, and sticked it back, and after that wasn't able to turn my device on with turn on/off button, just with turn on/turn off and volume down buttons. Now i can turn it on normally, but there is a huger issue with battery. It drains faster now, sometimes phone can turn off with no reason, and Nova Battery Tester shows sometimes +10c and after just 10 seconds temperature can become +60. Is it an issue with battery or what? Everything working good except battery.

Phone Will Not Boot. Stuck at Battery Icon.

A few days ago while charging my Moto X Pure, it suddenly turned off. I was not using the device, it was just lying on a table charging. When I go to turn the phone back on, it goes to the battery icon percentage screen and turns off again. I have no idea what happened. I tried to enter recovery mode and do a factory reset but it wont go into recovery mode either. It's the most bizarre thing that has happened and I have no idea what is wrong. The phone seems to work because it indicates that it is charging but it doesn't do anything else past that. PLEASE HELP.
Also, the phone doesn't turn on (and by turn on I mean go back to the battery screen) unless it is plugged in. That made me think it was a battery issue, but I don't understand if it was a battery issue, why it would restrict the phone booting regularly while it was plugged in.

Try charging it with laptop / desktop for a while 30 /40 mins.
Then try to boot into bootloader.
If you are successful then disconnect the USB and connect your turbo charger and start the phone.
