i've checked everything and turned everything off and checked wakelocks and crap.... i barely have anything running. no app and services are running that is wasting my battery, it's the OS itself.. i'm not that stupid that i can't figure what apps and services are running and what's not, ok?

also tell me how i was at 95%. i told me bro to call me,i he called me twice, i hung up twice and then i turned on wifi, went to cnet.com, then closed the browser and turned wifi. checked to make sure all those services from the apps were off. then looked at battery life and it dropped to 90%? and this was less than 5 mins....from 95% to 90% in less than 5 mins with 2 hung phone calls and one web page surfing...

when you put this phone into sleep mode, with screen turns off, it lasts really long...but that again that should be the case for ANY phone, so i'm not impressed at that.

but when you just use it slightly, the juice just drains so fast. extremely pointless to have a smartphone if i can't even use it for browsing or listening to music with fear of wasting battery. i might as well go back to a flip phone if i'm just going to use it for calls only and have the screen off most of the time.

Hi

I recommend downloading CPU Spy from the Play store. Reset the timers and let your phone sleep for 10 to 30 minutes then check how much time it recorded the phone being in Deep Sleep. This percentage should be in excess of 90%, you might find the deep sleep state was unused showing that something is keeping your phone from sleeping. This means the CPU is left powered up at 384MHz constantly which drains the battery.

There are some applications even with no wake lock permission that stop the phone from sleeping but DO NOT register in normal battery stats apps as keeping the phone active. These apps work perfectly fine on other devices. I think there is a bug in the kernel somewhere that stops the CPU from entering sleep mode correctly, perhaps when an application keeps a file lock or something similar and that this will be fixed in an update at some point.

If you find your phone isn't deep sleeping, you need to un-install applications one by one, note that even unstalling some applications may not solve the deep sleep issue until you restart the phone.

The other option is to reset back to factory defaults, confirm your phone is deep sleeping correctly, add back your applications one by one and check after each if the phone has stopped deep sleeping again.

My phone is currently deep sleeping in excess of 95% of the time and I can go hours without losing a single percentage point in battery power when the phone isn't being used even with the cell radio on.

The issue with the battery seemingly dropping quickly after just a simple phone call can be due to the fact it has drained a lot of power while it was supposedly asleep, but the battery percentage hasn't been updated. When the phone is next turned on, the battery level is updated after a short while showing bigger drops than expected.

Regards

Phil

After a good 10-12 days with my phone, I thought of giving my battery a closer look. It felt pretty reasonable all along but looking at some of the posts on here, I thought maybe it was time for me to take a closer look.

Yesterday I had installed the facebook app from the play store and today while I was getting bored in office, I opened up the facebook app. At the time, my phone had about 75% battery. I used facebook for about 8-10 minutes and then hit the homescreen and put my phone in my pocket.

About an hour later, I took out my phone and #@#$ the battery was at 40something %.

I looked at the battery usage and facebook app was on top. On further looking at how much time the CPU was awake etc, I found that the location had been running for more than an hour. This after I had disabled location for facebook app and turned off the location seetings on my phone.

Is this a case of rouge app or do I need to always close the app (by swiping right on the list of running apps)?

PS: I'll post some screenshots of battery stats once I get home.
[Nexus 4 General] calanizzle:
Disable location from the app (or from general settings if you don't use it at all), I also disable the app itself and receivers with Autorunmanager, and my FB app only shows CPU usage the exact time I use it..
[Nexus 4 General] droidd3v:
I had disabled the "messenger location services" under "app settings" within the facebook app the day I installed the app.

Is there anything else that I need to disable?
[Nexus 4 General] calanizzle:
Try BetterBatteryStats in order to see if FB is responsible of wakelocks
[Nexus 4 General] jinjin12:
swiping right don't close the apps... in many cases, the services are still running. you have to force stop it.

Maps and Android OS

My experience is the same, Android OS using most of the battery (mostly wakelocks), Screen next and then maps (mostly wakelocks)

Something with the location service seems to be keeping the phone awake on my phone. I don't know if this is an app that's constantly asking for location updates or the location service itself.
[Nexus 4 General] droidd3v:
well from the time of my previous post, FB has now $ucked up 33% of my total battery (currently 17 hrs+ on battery).

GPS usage (within FB app) shows 4+ hours now. I force stopped the app and that's not stopped this weird GPS usage!

I'm gonna uninstall this stupid app right away!

[Nexus 4 General] Cuttooth4:
Second full charge (I didn't bother charging out of the box)

A little disappointed by that. It's hopefully only down to my rubbish connection draining the battery and attempting to connect using WiFi (which eventually worked enough for a little while by constantly turning WiFi off and on). Might get better after a few cycles I guess.

Great phone otherwise, even if I haven't had much chance to set it up fully and get it the way I like because of the connection problems.

[Nexus 4 General] Younggun123:
I think Android needs better management of closed apps. Apps you close never seem to officially close until you do the "right" swipe on closed apps. They are most certainly still using resources. There should be an option to fully close, or exit to standby when you leave an app. At least there should be a close all button on that screen so you don't have to swipe right on each one.

I am personally getting great battery life, it's so easily lasts a day that I find myself randomly using my phone more than usual. I came from the one x running jelly Bean which had a wifi big that meant max screen I could get was 2 hours till dead. Currently on about 4 hours screen time with 22% left, and plus you can see from the discharge photo that I'm actually using the phone quit a lot.

Today:

30 minutes listening to music

20 minutes browsing

20 minutes listening to podcasts

10 minutes calls

Running:

He also had 4 hours on screen time, which means that in addition to what he had (1 hr 20 min) he had an additional 2 hr 40 min doing something else. Which is a lot. 4 hrs screen on time with 22% remaining gives a theoretical screen on time of nearly 6 hrs

What I find really strange is the comparison to the galaxy s3. Both have the same size battery. According to gsmarea battery test

galaxy iii

How in the world is web browsing competitive but video playback so far apart. That doesn't make sense to me.

Used it today and I got 9 hours with 3 hours screen on (no app making specific wakelock).

Personally I wouldn't go with faux for battery unless u know what u are doing and want to undervolt. If u want to flash and be done then I suggest matr1x or trinity.

To be honest I'm not sure. I just was told to try the one I suggested to u and I'm in love with it now. If you go to the rasbeanjelly thread they are the ones that suggested I use it and most of the trinity discussion goes on there. Trinity has been around for some time mainly on nexus devices and the GS3 now. In fact the Dev that created rasbeanjelly suggests that trinity be paired with his ROM. I've tried stock, Franco, matr1x, and trinity on rasbeanjelly and trinity is the best for me. In fact on xylon I perfered trinity over matr1x which was what I was using as my daily up until finding trinity was available on the N4. Loved trinity on my gnex

That's the thread. Alternatively you can download the kernel from his paid app. Personally have had more than 5 hours on more than one occasion. The g versions are compiled with Google tools and the l versions with linaro, and below it or not the g versions are better and more stable. For this device at least linaro is over rated

Games are running 60fps with this UV and battery life has become better. No thermal throttling which was the primary reason I used a custom kernel.
