[Q] Nexus 4 Random Reboots and Sudden Battery Drain, Stock 4.3 - Nexus 4 Q&A, Help & Troubleshooting

Hi,
Anyone know if this is solvable issue or anyone has any experience or ideas what's going on with my phone? My phone shuts down randomly and when i turn it on after few seconds, it has appx 5-10% less battery then before!! it has happened 3 times in last 10 days already.. And really frustrating..
I don't have any shady apps and using stock 4.3 so no rooting as well..

How to get kitkat on N4?! I thought its not out yet!!

Hey lex,
Try downloading 'BetterBatteryStats' from XDA, and 'Wakelock Detector'. Both of these apps can help you pinpoint what is draining your battery. With 4.3 I found that I had a kernel wakelock issue that was fixed by keeping wifi on. Best of luck!

bet it's one of those strange android problems that are fixed with a reboot
Flash the stock google image and see if it persists. I bet it's just a gapps issue (hence the weird Calendar Storage usage).
Google Now since it's release has been known to be a battery hog. I keep it turned off if I choose to not be connected to a charger all day.

that problem persists on Jelly Beam 4.1.1 and 4.1.2

Battery drain/ sudden shutdown

Hi just wondering if anyone else has had a issue with the battery suddenly having reduced charge. Over the last few days my wife has been complaining about her phone discharging in only a few hours. I thought an app might be causing it but I've looked and can't find anything that would cause wakelocks. Now she's complaining that the phone has shutdown after showing a 70-80% charge and then when it started back up was nearly empty. Has anyone else experienced this or can recommend a possible fix please? I'm going to try a factory reset when I get home from work but would appreciate any advise.

Battery drain... Is this normal?

Hi Guys,
I am getting a massive battery drain over night while the screen is locked.
This doesn't make sense to me. I am rooted with Arter97 Kernel and the deodoxed rom from here http://forum.xda-developers.com/s6-edge-plus/development/deodexed-aoh3-t3195044
It was working fine a few days ago.
I have attached some pictures.

If it started a few days ago, its most likely some stuff you changed? Try uninstall apps you recently installed, might help.
Seems you have very bad phone signal. Turn airplane mode on then turn on wifi and let it idle for 2 hours and see how much it drains

for me, i had issue with whatsapp after an updated. I uninstalled the update and disable whatsapps. and reinstalled and enabled it again and that solved it for me. If that dones't solve it, uninstall all the apps that you downloaded and isolate what is causing the wakelock.
I think that its some apps from system, not apps that i downloaded. But i will try, thanks
Edit
I tried but same problem, pls help someone

5.0.2 Battery problem (hard resetted a few times)

Hi everyone!
Everything what I write is about stock rom:
After upgrading from Jellybean to Lolipop, I had a serious battery drain problems because of "Android System" even though I did hard reset a few times. I decided to go bback to Kitkat and had no problem with it. But nowadays I wanted to use Lollipop again thanks to its design and upgraded to 5.0.2 TRV30d with PCSuite. But still I have this problem, "Android System" uses a lot battery. I
You can see battery usage statistics, there is a problem with Android System in Lollipop but I can't understand the problem. I need your help guys!
I've only talked for 5 mins and connected to Wifi most of the time. I never turned on GPS, Bluetooth or NFC.

Install better battery stats to catch the root cause
