I've noticed that my Android System usage is really high..And it's always been like that..Looking at the screenshots of other people..Everybody seems to have Less than 10%...But in my case...Android system is always at 15% and even higher sometimes..

Is it Signal problem or some other thing?

Tried many kernels but Android system % is always high in all..

It's 'powermanagerservices' kernel wakelock which eats most of my battery..

In each charge cycle,1 hour is spent in wakelocks only..If my Avg sot is 3hrs,phone on the other hand is awake for another hour or so due to wakelock..Android system % also increases

Guys,

I changed to ART at around 60% batt lvl. I noticed a starp drop from arnd 22% to 12% (depicted in yellow). Any explanations for this. Is it a case of confused battery stats?

Will it sort itself out from my next charge onwards?
[Nexus 4 General] ogrillion:
Had a question figured this is as good of a place as any to post it. I have a Nexus 4 and a Nexus 7 2013 model. On my tablet I used to always turn off sync and set wifi to turn off when device sleeps (don't need push notifications etc since I use my phone)

Now I am pretty sure on battery stats screen I would see the WIFI blue bar turn off when the device sleeps. Well all of a sudden (I want to say since 4.4.2) wifi bar stays solid blue all the time. I disabled google wifi always scanning option, double checked that the device is set to never leave wifi on, and also I have checked for any wakelocks - can't find anything.

Now I set the same options on my nexus 4 - and this also won't turn wifi off when the device sleeps. Like sometimes I will see the wifi is disconnected and the phone is using 3g - but the wifi bar stays solid.

Am I imagining things, did the wifi blue bar never actually turn off when the device sleeps?

The reason I am even questioning all this is under battery usage on both devices WIFI is generally top (when the device idles for awhile not necessarily when I am using it - screen is then top.

I just never recall ever seeing wifi close to the top for any of my nexus devices.

Just factory reset the tablet and didn't restore anything and I am seeing the same behavior. Maybe I am just crazy =/ lol.

That is a new feature in android kit kat.

It keeps wifi on all the time even when you have switched it off. It is used for location services. You can disable it by going to settings wifi advanced and untick scanning always available. You would get the blue line denoting wifi on after that.

WakeLock Android OS

I have an issue since 4.3, sometimes Android OS keeps phone awake for hours draining the battery. I thought that it was random at first, phone could be fine for a day or two but lately I noticed (or I'm imagining things since this is driving me crazy - checking batt level frequently) that wakelocks happen when on mobile data not WiFi and when I'm at work when the mobile signal drops in the elevator. Once I get out the signal is back, works fine (notifications) but I suspect some system app or whatever doesn't quite get it that the signal is back on. After reboot, phone works fine. Could someone advise me how can I pinpoint the time/issue so I can provide accurate data? I'm on 4.4.2 now.

Thank you in advance.

I only got 2 hours on 3g. What launcher do you use fellas?
[Nexus 4 General] ViperExhibit:
So just got my (used) Nexus 4 yesterday as my replacement for the Nexus 5 I was trying out before and I must say I'm impressed with it so far. I've had 3 phones within the last month for testing to see what I'd like to go with (Nexus 5, Moto G, & now the Nexus 4) and while the Moto G had the best battery out of the 3, my Nexus 4 so far is killing my N5 in battery life. I never got over 4.5 hours of SOT on the N5. Since I got the N4 last night, all I've done is rooted it & flashed the LTE for it. No kernals and I kept it on the stock 4.4.0 it came with. I'm kind of scared to upgrade to 4.4.2 and lose the battery life I've been getting so far (this is my first charge cycle so I'll have to test other heavier usage cycles).

Took it off the charger before I went to sleep early this morning and then used it pretty "lightly" for the day. When the college football bowl games started, I went on Twitter and kept the screen on all throughout the games just checking the tweets and refreshing every 1-4 minutes. The last screenshot is the one I took right when I received the phone yesterday which I noticed said it had 9 days of standby time. The phone was dead when I received it (that's why it's on charge and at 3%) so I don't really know if the 9 days is correct or whatever, but I thought it was interesting anyways.

I had the Nexus 4 for 10 months (just sold it on eBay today) and got a Nexus 5 for Christmas. My impression of the battery life of the two phones is totally opposite of what you have. I loved my Nexus 4, but its battery life was not very good. I have had my Nexus 5 on LTE all day at work and used it on an off throughout the day. After I got home, the Nexus 5 still had around 20% life still left in it at 6 PM. If I used my Nexus 4 like that, it would have had to be put on the charger around 3 PM.
[Nexus 4 General] ViperExhibit:
Ya I guess I got a bad Nexus 5 or maybe my software was buggy or something cause I know that it doesn't make sense for the my Nexus 4 to be so much better then my Nexus 5 (based on what I read on the forums), but that's just the way it was. I put the N5 through some heavy testing with different kernels, settings, etc. and nothing seemed to work. I never got good life out of it. And then the first time I used my Nexus 4 I ended up getting 6, 7, 8+ hours of SOT and ever since then with heavier usage, it's still doing way better then my N5 (never even touched 5 with the N5). I'm sure my case is not the usual because like I said I may have had a bad N5 so that may be why, but for a ~$232 saving, I'll be happy to stick with my N4 until maybe the next Nexus comes out :)

Edit: I just went over my post and I didn't mean to make it sound like the N5's battery life is bad in any way. I just meant to say that in my case, the N4 was getting better life than my N5. The N5 is still a great phone and for the 4.5 hours of SOT I was getting, that is actually pretty decent. It's just that I preferred the extra hours I'm getting on my N4 rather then all the nicer features that the N5 has.

What kind battery does anyone get with mostly bad signal and on 3g. Im getting horrible battery life. I don't have any rogue apps pulling juice but I do have location on in battery mode. Facebook pulls every 4 hrs. Stock 4.4.2 with Franco 200
[Nexus 4 General] usama990:
can anyone help me with this? i've been having pretty bad battery life for the last few months, but before that it was what i considered normal. the main problem now is that the battery is draining way too much when idling. as you can see from the attached pictures the phone was in DEEP SLEEP for most of the time but still the phone was draining at something like 2%/hour. The problem is not a wakelock one i think, as the phone does seem to go to sleep but is draining unusually in that mode. On rare occasions i seem to get the normal drain when idling, but that lasts only for a short time and then the draining starts again (you can see this in the graph too). i've tried a few rom+kernel combos too but none of them fixed this issue.

currently using PA beta 4.0 + matrix v12 on .98 radio. Any help will be appreciated :)
[Nexus 4 General] mor_1228:
1. do check for wake locks

2. use greenify

i suggest you do a clean flash with

Rom : purity 4/01 build

kernel : hellscore hells-Core_b42-n-kk_anykernel.zip
[Nexus 4 General] usama990:
1. well i do check for wakelocks but the reason i left it out of the picture is because the phone seems to get enough (or normal) deep sleep but drains more than it should WHILE in deep sleep.

2. i'll try it and see what happens. thanks :)

3. i did a couple of clean flashes in the last few months (before installing PA and before upgrading to KK for example). i started having the problem from 4.3, that is to say, it started while on 4.3 but not immediately after installing 4.3. and i've tried hells core kernel with PA 4.0, but that didn't help. haven't tried purity though

17hrs is great considering the 2100mAH battery, I mean how many hours were you pulling before you've had this "problem". I suggest turning off wifi during the times you're not using it. Also turn off location/gps other apps that you're not really using at the moment. At the N5 forums, 17hrs would get you a lot of people asking what tweaks you do on your phone :) :good:
[Nexus 4 General] usama990:
actually i didn't use the phone a lot so so 17 hours isn't much. The thing is that , the standby drain is too much. i used to get around 4 hours SOT in a day but now it barely goes upto 2 hours. This is NOT because the battery drains a lot when the phone is on but its because the battery drains a lot when its asleep. And yeah i keep wifi off when im not gonna be using it for long a long time (when im sleeping or outside for example).
[Nexus 4 General] ickoicko:
Do you have BetterBatteryStats app? can you post a screenshot for us to see what wakelock keeps your phone awake even if it's in deep sleep. Post a screenie also when you're using the phone; the 17hrs SS was kinda confusing, in my opinion.

[Nexus 4 General] Federico_96:
I noticed that my battery drain while the phone is in idle is increased and in the apps running in the background I see 2 apps called google play services, the first one is gcm service and I think that is normal since i use hanghouts and whatsapp so google cloud messaging. The other one has 2 services : GoogleLocationManager and NIpLocationReceiverService, but these services shouldn't run in the background because I disabled all gps and location settings. Is it normal to have these 2 location services always running in the background? Maybe i didn't disabled all location reports in the apps (the only apps installed that could use my location are the gapps btw) any advices?

just a question. what % drain were u expecting when the phone is in deep sleep?

i too experience a situation similar to yours, but i'm getting about 1.5%/hour when the phone is deep sleep at night.

is this considered acceptable?
[Nexus 4 General] Rohit02:
Idle time on KITKAT based ROMs is THE BEST..

I keep my data off while sleeping and get 0%,yes you read right. 0% battery drain overnight(8hrs sleep:P)

You can try different ROMS and kernel combos.. During day I have some 2-3% drain per hour if on Idle time(all sync on).
[Nexus 4 General] ViperExhibit:
No trick. All I did was root it and then flash the LTE radio for it. No ROMs or kernels and stock 4.4.0. And it was my first charge cycle with the phone ever. However, I will admit it was pretty light usage. Like I said, all I did all day was run Twitter and refresh the feed every 1-3 minutes. But 8 hours of screen on time is still very great for the N4 and especially for my first charge cycle. I doubt I'll be beating that ever again. Unless I just leave the screen on all day doing nothing.

And by the way I've had the Moto G (for like 3 or 5 days) but I will say that I used the Moto G in heavier conditions then I did my N4 and it lasted 8+ hours SOT for me. The Moto G has a beast of a battery and I could've probably easily gotten more out of it if I didn't play games and watch movies on that specific charge. If I used Twitter all day on it like I did with the N4 maybe I could've gotten 9 or 10+ hours with it. I'm gonna miss that Moto G.
[Nexus 4 General] ickoicko:
Turn off GPS, WiFi, and location services unless you need to use them. Those wakelocks stem from those 3 I mentioned
[Nexus 4 General] Federico_96:
Thank you for your answer, I already turned off GPS (I never use it) and sometimes i use wi-fi, I installed wakelock detector and my awake percentage is 1% so 99% deep sleep...maybe is just in my head, but imo the location services shouldn't run if my gps is off, maybe is a setting in some app like maps that even if I don't use maps activates this location service...I'll keep trying

Google Maps, Weather App (if you have one) Google Now. That NLP wakelock is also a culprit in the N5 forums and the link is here for your reference :)

[Nexus 4 General] yugimonster:
only 0.5%/hr? then something must be wrong with my phone.

i'm on franco r201 + stock 4.4.2. in addition, i also have TouchControl installed and enabled.

i usually go to sleep with 100% (with WIFI turned on throughout the night) and in 6 hours, it drops to 90%.

I always thought that was normal, but it seems like i should only get a 3% drop for that duration. Under Battery information, i don't see any rogue apps eating my battery up through the night. Phone Idle, Android OS, Android System, Cell Standby and WIFI.

Will monitor tonight and see the percentage of Deep Sleep I get and any particular wakelocks.

Really like this thread, I am currently using AK's xGenesis v15, Its basically stock kernel with custom MPD and a few add-ons.

My question is for the governor settings, I'm currently using on demand and have interactive also. What should i focus on? Is it lower clock speeds and let them or going to high speeds first? I have on demand set with high thresholds so the CPU ramps up slowly. I like the results so far but won't know until I have ran down the battery.
