Does anyone know what's causing this?
So, we cause a triple murder before breakfast, start a race war before dinner - that's uh, that's a pretty good day.

Well...I'm pretty sure that restarting your phone uses a good chunk of it's battery seeing as you are stopping everything and then re-opening it basically.

maybe you must calibrate your battery, or try 2-3 full cycle battery charging..sorry just my simple thought

worth the try,tx for the input!

Sometimes after a kernel install the battery stat is incorrectly reflected...a reboot would pick this up but as has been mentioned, give it a couple of full cycles and see if you still have the issue.

Download battery calibration from playstore and do the calibration.

Battery stats out of sync, help needed

Hi guys,
I charged battery till fully charged yesterday and I went to flash a firmware upgrade which took about 15 minutes in total and thereafter when my phone restarted, it showed me 39%, a huge 61% drop during this process and I checked the battery voltages in fastboot getvar all and using gsam battery app, it still showed me 4.2-4.3V which is usually a full charged battery. Now after charging a while, it suddenly goes back to 100%, any idea is this normal? This is the first time this is happening.
Hope to get some help and advice around here, thanks guys.
Screenshots after charging over an hour:
Just plugged into charger:

You need to re-calibrate your battery. There are a few different ways I've read people doing it. I usually just let it totally drain, then charge it to full again without messing around with it. You may want to search for a proper method.

[WorkAround] Delayed Notifications Nexus 4

Hello guys, finally i have found a good workaround for this issue which affect most of nexus 4 devices.
Let me explain the scenario : Leave the phone in deep sleep for some minutes and try to send a notification, you will get it delayed. Also you can try to ping your device via Computer, you will notice the ping average very high
Below the workaround. Install this app https://play.google.com/store/apps/details?id=com.gejos.android.wakemyandroidpro
Set it like the screenshots below

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Leave the app active, you will have a wakelock every 29 seconds which wake your phone from death sleep (no notifications), without screen goes on (its an invisible wakelock)
You will notice an improvement in notifications no more delayed more of 60 seconds.
Important This app could drain your battery a bit, but still better to turn off wifi optimization which makes your battery life ****ty and android os in battery stats. Im on hellscore and im getting an awesome battery life with this app (1 day of medium usage) .Try to believe.
Cheers, Xda_Emanuel

Thank You Emanuel. Will try and report back.

M7 always awake after switching to Sense 6.0

I upgraded to sense 6.0 yesterday and now my phone is pretty much always awake, causing massive battery drains. Not sure what the update did to cause this. My phone isnt rooted, so any suggestions on how I can solve this?

Please post some screens from battery monitoring apps (GSAM, BBS) which apps are causing drain and what is causing the wakelocks.

I have had the same problem. I have down loaded screen off wifi off to help with the wifi staying in, but staying awake I have found I have to reboot after pulling it off the charger for my phone to actually go into sleep mode when the screen is off. We shouldn't have to but until it's fixed try that.

I have used ViperOne for my HTC One, With greenify app, I have no wakelocks when my device go into sleep

Same issue for me. Early morning after pulling of the charger, I have to reboot my HTC one m7, else the phone stays in awake mode and drain is higher. With a reboot I get fantastic battery performance.

[Q] Sudden battery drain

I've had this phone for about a week and this is the first instance where my phone has gone down to 10% battery in the matter in 8 hours with what I can only describe is light use. I get a few emails, most of the time it sits with the screen off. I checked the battery stats and saw Android OS at 21% usage followed by Cell Standby and Screen.
I am rooted at 5.0.1 but stock and encrypted. Only mods I have done is DPI at 493 and double tap to wake.
Anyone else experienced this before?

So I've been having that issue the past couple days too. I installed a program called BetterBatteryStats.
Yesterday I fired it up after having about half my battery drain in a matter of a few hours.
I saw that my deep sleep was about 3 hours, my awake was 8 or so hours but my screen on was only about 1 hour. Something was keeping my phone from sleeping.
I went threw and uninstalled everything I could think of that had either updated or been added since it started and now it seems to be sleeping again so I'd look at installed apps and updates.
