Nexus 4 - 8gb: Pathetic battery life and Overheating :( Please help!

I have a 8gb Nexus 4 imported from USA ( no warranties :( )

My device is running stock 4.2.2 build. I'm getting pathetic battery life and the device overheats (especially near the camera, just above the Nexus logo) even on light usage (browsing on Chrome, playing Temple Run for ~5mins)

Anyone facing such issues? Is there any way to fix it?

One person suggested me to flash all stock components again, but I can't do it right now because I recently moved into a new location and my broadband's not running yet.

Please help!

hi guys, i have a lot of disconnects with my bluetooth headset (either samsung hm1500 or sony mw1)..

i have seen quite a few references regarding this issue..while some report that they don't have such issue..

sounds like a software issue waiting to be resolved? or perhaps hardware one so i need to return the device?

Wifi doesn't go to sleep

Hi All,

I'm running stock Andriod 4.2.2 on my Nexus 4 16 GB (non-rooted). My wifi doesn't go to sleep when my phone goes to deep sleep. It seems it runs continuosly no matter what settings I choose - "Always on", "On when plugged in" or "Never". I hv wifi optimization option checked. But when I go under battery details in settings, the Wifi Bar is full blue through out the duration. Better Battery Stats does show my phone goes in deepl sleep but the constand wifi running is not allowing me enough backup. On my earlier device on 4.0.4 I had the same setting (wifi, 3G, Sync & GPS always on), but never faced the issue of wifi continuously running in the background. This happens even when I'm not latched on to a wifi network and am on 3G (cellular connection). I have prompt for open networks options turned off but isn't helping.

I can't root my phone because of my corporate IT apps running which stop working on rooted phones (temp unroot doesn't help either). Please suggest is there a solution for this?

@payne: sounds weired.

Stock users don't restart their phones from time to time since they not flashing roms.so try this first.

Some recommend discarding all known WiFi connections,restarting router and connecting to it again.

Could be your phone is trying to connect the whole time and the above helps.let us know.

Hi,

I just factory reset my phone couple of days ago and I'm still facing the same issue. I think the wifi isn't designed to go to sleep even when the phone is sleeping. Because the wifi on time and wifi running time both are same for me. I tried disconnecting from my router and reconnecting, etc. Doesn't work. Also once I move out of my house and am not connected to any wifi hotspot or access point it still keeps running even though its using 3G HSPA for network connectivity. Any one faced the same issue?

Does everyone else have the 3G data sending delay?

Hi. This bug hasn't been getting much attention, so I'm wondering if some people aren't experiencing it? The issue is this: say you try to send some data when the phone is in HSPA mode (on Cyanogenmod this has a "H" icon, but on stock there's no way to tell the difference--this is the phone's normal state when you're on 3G but not sending/receiving a lot of data). Maybe you're sending a WhatsApp message, maybe you click a link on a web site, maybe you do something else. The phone attempts to change to HSPA+ (this has a H+ icon on some custom ROMs). The data isn't sent until the transition to HSPA+ happens, and this can take from 10 seconds to 1 minute. This is a serious issue, but I can't tell whether it only affects my carrier or whether everyone is suffering and just hasn't noticed because they don't chat a lot. Anybody?

Re: [OFFICIAL] Nexus 4 Android 4.2.2 FAQ, Q&A, Help & Troubleshooting Thread

Hi guys, I'm getting a non responsive touch screen along the left and the right border of my phone. It's a minor issue and I hope one of you can come up with an answer to this problem of mine.

I am not able to move any apps to another page (on the desktop) because of this. Nor am I able to set the location of pie controls (PA rom) on the right/left border unless I set the trigger area to huge, which is a pain in the ass because setting it to huge would make typing harder (unresponsive backspace etc).

I don't know what I did to f this up like this, I don't know where to post this other than here, because I don't know if this rom related, or kernel related or whatever. Any help would be appreciated.

Here's my setup:

4.2.2, latest bootloader and radio

PA rom

Franco kernel

Nova launcher

GMD gesture control

Have you tried rebooting the phone? Give that a try first. If that still doesn't work, go to Manage Apps, Camera and wipe data.

Try uninstalling touch control and gesture control first. If that doesn't work, make a nandroid backup and then flash a stock rom. You want to figure out whether it's a hardware or software problem.

Do I need to wipe my phone to flash the same exact stock rom?

A while back, my Play Store went bonkers and I couldn't access it. So I downloaded GAPPS from some site and flash it. Everything worked great except that now, every time I restart my phone, It would say "Android is updating" and then it would count some 89 apps. I tried everything I googled including clearing every possible cache there is but to no anvil. Every time I reboot, it will update. AFAIK, it's rebuilding the dalvik cache. But I'm sure nothing is wiping it when I restart the phone. I didn't have anything additional installed before nor after flashing GAPPS.

I've read that the only way to fix this "update" thing is to re-flash the phone. Now my question is, if I flash the same stock 4.2.2 on top of the current system, do I need a data wipe or will it mess up any of my current settings if I don't? I've done some customizations and stuff that took some time to do and I would hate to do it all over again.

This is my first Android phone. It's rooted and unlocked already. Any help would be greatly appreciated.

Thanks for the quick reply. So I guess there is no way to just flash the stock rom (exact same build) over the exiting one to fix any "bugs"?

2.	Using ES File Explorer or equivalent application (You also have enabled ES File Explorer Root Settings, just into ES FE settings)

3.	Go into /system/vendor/firmware/keymaster directory

4.	Once, in the keymaster directory, you will need to change the permissions from 400 to 644 or rw-r--r-- to all the files within the keymaster directory.

---------- Post added at 03:09 PM ---------- Previous post was at 03:03 PM ----------

Hey! You don't really have to worry about flashing another kernel before switching to another one, unless it is Franco kernel, which modifies the ramdisk. If that were the case, you could just dirty flash the current ROM you're on (only wipe cache and Dalvik cache, you don't have to factory reset), which is the easiest way to flash whatever kernel came prebuilt in your ROM.

Just to be on the safe side, here's what you should do:

-make sure the other kernel.zip is in your storage

-make sure the ROM.zip file you're currently running is in your storage (in your case, PA)

-boot into recovery

-wipe cache

-go into advanced > wipe dalvik cache

-flash the ROM you're currently on

-reboot (now you are back on PA's kernel that comes prebuilt in the ROM)

-boot back into recovery

-wipe cache

-wipe dalvik

-flash new kernel.zip (whatever you want, I'd recommend Trinity!).

-reboot.

Following those steps should prevent bootloop due to some kernels modifying ramdisk like I mentioned above. Happy flashing!

---------- Post added at 03:18 PM ---------- Previous post was at 03:09 PM ----------

I've had this issue with other phones before, and sometimes on my nexus 4. The trouble likely isn't with your phone: it's with the outlet you're using or the usb cable.

Double check your cord isn't damaged, or try using a different one. Try using different outlets to plug it in. For me, what seemed to be the trouble is that if the phone wasn't connected properly, the power from the outlet effected the digitizer. Make sure the cable has no kinks and that the outlet you're plugging it in to isn't malfunctioning, so you know the electricity has a smooth, unobstructed path to your device. This should avoid what I called "electric surge" that was making my touch screen less responsive to touch. (The same also happened when plugging it in to a foreign outlet without a current converter. people who have travelled to countries with different outlets should be able to vouch for this with certain phones).

Of course, the problem might not be your cable or outlet, in which case your usb port on your phone could be damaged.

Nexus 4 and DC-HSDPA

Does anyone know if it's possible to tell when the N4 is connected to DC-HSDPA?

I will assume that it will just say H in the status bar, and not DC or anything else.

But will it say DC-HSDPA when you go to settings and view phone status?

I know that it shows GPRS, EDGE, UMTS, HSDPA, HSPA and HSPA+

I have recently moved to Three UK and I am living in a DC-HSDPA area, and yesterday I went around London deliberately going into DC-HSDPA areas and it still didn't say I was connected to DC-HSDPA, and the highest speedtest I got was around 9Mb/s, which is what I usually get on HSPA+ (which is what it said it was connected to).

I am basically just wondering whether my phone has an issue connecting to DC-HSDPA networks.

EDIT: Just received an email from someone who develops a "network information" app, they told me that checking whether the phone is connected to DC-HSDPA is not available through the API, which shows why it doesn't show being connected to DC-HSDPA. That still doesn't explain the speedtest results.
