[Nexus 4 General] T.E.C.H.N.O:
Yeah right, I thought I forgot something :D

My settings are:

-125mV

- EcoMode (2 Cores disabled)

- 384-1512Mhz

- interactive gorevenor

- intelliplug hotplug driver instead mpdecision

- 128mhz GPU Frequenzy Max.

(This maybe seems to be a speed limitation for the device to some of you, but my experience is a smooth interface and smooth system! Maybe the animations take longer some times but if i can double my batterylifetime by that, I accept that.)

[Nexus 4 General] asrivastava:
I've had my Nexus 4 for a day now, this after I hadn't used it for close to 9 months.

After a full charge today morning I took it out at 9 am, and the following were the results.

https://i.imgur.com/skckUg2.png

Battery lasted for 6 hours 20 mins.

Screen on time 2 hours 50 mins.

Hangouts video call for an hour.

Chrome for 20 mins.

And YouTube for a while.

I think this is just average battery life, and a bit below what I expected. :/
[Nexus 4 General] Feahnor:
The problem was the hangouts call, it's a sucker for battery.
[Nexus 4 General] shaggydiamond:
brightness on minimal? what if you have to actually leave the house:silly:
[Nexus 4 General] Snyper0012:
To prevent inconsistencies with brightness why doesnt everyone set their screen on to max while doing this test? That will produce more realistic results. Anybody can get 5+hours with max brightness. I on the other hand can reach 4 hours max brightness browsing web watching videos and listening to music
[Nexus 4 General] taita87:
I'm experiencing battery drain due to this process and I can't figure out what's causing it...

I'm on pa 4.1 and latest Franco, and I never listen to music... Audiomix is in constant raising... Now I'm at 6 minutes
[Nexus 4 General] taita87:
I solved it switching from Franco kernel to hells doctor
[Nexus 4 General] xenyz:
If you're experiencing battery drain, it's not from that process, which is the Google Now launcher listening for 'Okay Google' hotword while you're on your home screen or Google Now.

[Nexus 4 General] djkinetic:
Well I finally solved my battery drain issues, what I did was this: disable google now, disable location reporting in maps and location settings, then disable in mobile networks all broadcast options, then lastly what made the most difference is that I noticed my phone would hover between 1100 mhz and 384 mhz in idle, many times it would not drop back to 384, so I used voltage control to set the min cpu to 384 and it now stays there and deep sleep when the phone is not in use. am now at 54 percent 18hrs in and 1 hr of screen time, on the first charge cycle since a fresh rom flash.

[Nexus 4 General] akash3656:
That's pretty awesome battery life up there. But your screenshot reminds me of those who on the Gnex were getting 5h screen on while I get 3-4h. Guess everyone's usage isn't the same and maybe my battery takes heavy abuse that its life has decreased.

[Nexus 4 General] golfinggino:
i got 4.5 hours screen on time yesterday with matr1x kernel, it was an average day for me - emails, internet, etc. also had about 45 minutes of gps usage in there, i would consider myself a heavy user

i flashed the jr1 rom as i need the stock email app and cant get it working on other roms, still running matr1x kernel, the big difference is that i have enabled lte and i am curious on how that will affect the battery, i will run it to 0 today and post my results later
[Nexus 4 General] Hemlocke:
Sounds like you are in good shape there. I would try a wipe and set the device up again. If it is still awful, you may just have a defective unit. That's my two cents. Google services will impact battery life, as will wakelocks, but not that much.
[Nexus 4 General] ksc6000:
Shouldn't we be a little realistic? First of all my nexus 7 gives me about 8 hours of screen on time usually. It has a 4300mah battery. More than double in size. Now that I think about it, how was I expecting the nexus 4, which has a higher Res screen and is connecting to a cell tower at all times to match that?

Secondly look at the screen on times in the optimus g forums. They're pretty similar to ours. Barely anyone cracking 5 hours. Despite what the rundown tests from engadget and anandtech show.
[Nexus 4 General] drewden123:
I went ahead and bought Juice Defender Ultimate, and I also installed Matr1x kernel. I also disabled a ton of Google apps like Currents, Magazines, Movies. Battery life is going on 16 hours with ~2.5 hours screen on time. Still, Mediaserver is sucking more power than I'd like it to. It's also a bit annoying to have to go through all these hoops and precautions just to get decent battery life :( but I still love my N4.
[Nexus 4 General] akash3656:
Mediaserver appears when audio is played. It can be a video, or some app that plays audio and even the OS touch sounds. Mediaserver wavelock is quite normal. It shouldn't appear if you aren't doing anything that causes audio to output.

Btw, Juice Defender drains more battery than it saves for me. Check your wavelocks and you will see juice defender waking up your phone unnecessarily.

velocityrom get the best battery ever without stupid sttings as underclock or keep minimal brithness
[Nexus 4 General] xenyz:
Decided to try out the new Furnace 1.0.2. It's kind of a souped up faux kernel with intelliplug and intelligovs. Ran with intelliactive (defaults except hispeed 1350 MHz) and used the apps shown on WLAN only all day.

Edit: ROM is stock KitKat 4.4.4 w/ optimized dalvik & bionic libs from the Z2, root, Xposed, etc. Auto brightness, Location, Google Now all on.
[Nexus 4 General] Curl3w:
not bad at all. wifi all day? i was on matr1x but didnt get no more than 4h SOT, but i was on stock rom... what is your cpu gov and scheduler? right now im testing purity and hells doctor.

wow! wifi all day? scheduler? and the gov is intelliactive, right?
[Nexus 4 General] iDon't:
Yes, it was wifi all day, mostly it was tapatalk and browsing, with maybe 20 min if games. Every settings were default I didn't change anything.

Anyway, I rather have better performance over battery, so I went back to Franco (r210), and first few days were also very good. WiFi all day and default settings.
[Nexus 4 General] migueldbr:
i get around 5h+ sot with franco 210 and purity(but i dont have wifi all day...and use 2G)
[Nexus 4 General] xenyz:
Yes only WLAN, no calls. Using it as a mini tablet if you will.

CPU gov is intelliactive as recommended by faux, IO scheduler is the kernel default, deadline. (I really doubt the IO scheduler has any impact on battery, BTW)

What's interesting and I've yet to try is faux recommended settings on the N4 of 1.7 GHz max frequency and intelliactive hispeed 1.5 GHz. I wonder why he recommends overclocking the mako to everyone.
[Nexus 4 General] Curl3w:
ok tks! i got a good performance in benchs tests with matr1x ( i do not play so much). about franco's kernel, i only used the r209, good perfomance but i didnt get the battery life that i was expected (~5h SOT) so i'm moving and testing some kernels :D

tks! only wlan? or some sms,etc (2G and 3G signal)? the SOT you got was pretty amazing and the features of the kernel are interesting too. maybe i will give a try on that one!
[Nexus 4 General] Almayce:
I started to think that some batteries are just better than others. No matter what kernel I flash, be it battery friendly or performance driven I get around same sot everytime. Now my setup is fairly the same on each one. I go with ondemand governor or interactive, I uv by 100 from stock values, decrease the max freq to around 1200. I don't believe schedulers do much, but I use row, deadline usually with 128 read ahead if it helps. The phone is 6 months old or so, so battery should be okay still. Greenify didn't do thing for me. No wakelocks no gapps drain nothing. I get only around 3 hours of sot on WiFi and im just on tapatalk, chrome, messenger etc, no games. I don't believe can do anything more to change it. This is just a general rant about my battery, but if you do have suggestions what to do, I'll gladly read them :)

It's just I've seen so many users have the best battery, getting six hours of sot doing nothing special. I've also seen mediocre users getting 4,5 h and then there's users like me, who are lucky to reach 3 hours.
[Nexus 4 General] sidnoit22:
How much older is your battery is also an major point. Mine is 2 year old now and i get 4 hour of SOT Max.
[Nexus 4 General] Almayce:
So if I understand correctly, you're saying that my battery can be way older than my phone? If that's not what you meant, I wrote in my post that the phone itself is 6 months old or so(that's when I bought it that is) and it was new, definitely.

Here is today's example for instance :

You see, and it was like 80% WiFi. I used navi for like 10-15 mins so that's 10 % down for sure, burns the battery so darn fast. This is very bad I dare say. This is Mahdi + latest Franco by the way, but like I said the kernels do very little difference for me.
[Nexus 4 General] xenyz:
From my experience, kernels make a huge difference. I've also found that with franco's kernel you get great performance, but it definitely uses more energy. If you are interested in battery life, I cannot recommend using franco.

Which others have you tried, if any?
[Nexus 4 General] Almayce:
You see, I've tried almost all of them. And the thing is, I only noticed performance differences, battery was pretty much the same. I must say though hells and matrix were probably a tad better than others. But I want something between battery and performance, because when and if I decide to play, say, asphalt I'd be able to without lagging(which happened on those two aforementioned kernels). I tried Mirage as well (I read you had some very good results with it), naruka as well. Still around 3 h of sot. Franco which I'm trying right now is between 2-3 as well. From Poseidon series I ve been on ak as well, it's very good kernel, too bad the development had stopped. But seeing as nothing satisfies me I might as well stick with the latest one. I briefly tried trinity too, gonna do so in near future again to test it better. For some reason semaphore doesn't like my phone as I get random reboots no matter the version with stock voltages and everything, so that's that. Inception was also decent, but there are too many changes at so I'm waiting for it to stabilise. Basically I've tried almost every other kernel there is. Now I have flashed latest faux and trying it out. Gonna give it few days. If you say flash this kernel and put these settings in and you should get at least 4h of sot with browsing tapatalk, chrome, g+, messenger etc I'd gladly do it, because that's basically all I do on the phone.
[Nexus 4 General] xenyz:
You'll probably have good results with faux. Have you seen his recommended settings?
[Nexus 4 General] Almayce:
Thanks, all set with minor differences as I'm on mainline not ultimate one. We'll see.
[Nexus 4 General] sidnoit22:
Check your background apps like Facebook apps ( msgnger too ) and other apps. They keep running in background make huge battery impact. And i meant your phone starts to age a brand new nexus 4 vs 2 years use nexus 4 both will have different battries stats.
[Nexus 4 General] Almayce:
Well this is a "tad" better :)

That's the first cycle with fauxes reccomended settings. :) So far I'm not getting my hopes up though as the first cycle tends to be the best for me.

[Nexus 4 General] Flipz77:
I honestly don't see the point in OCing an already snappy phone like the n4, especially if you're after battery life.
[Nexus 4 General] dentillozie:
if you are a poweruser OCing can improve battery life (only by a tiny bit) cuz tasks are done more quickly so the Cpu and the radios can go back to idle faster.
[Nexus 4 General] RASTAVIPER:
Which standard application exactly is not running fast enough with the stock max frequency of 1500mhz?

Unleashed by my Nexus 4
[Nexus 4 General] Flipz77:
I notice absolutely no lags or hesitations with the overall max frequency capped at 1242, and there's a good number of apps you wouldn't say are able to run at max 918 MHz cpu, 320 MHz gpu without the smallest slowdown. Obviously the 1512 freq comes in handy for heavier apps, but with Per-App Modes all of this is more than easy to configure. Heck, I have all of my messaging apps (plus some other light ones) running (and I say "running", not "stuttering") at 810 MHz cpu, permanent dual core, 200 MHz gpu. Needless to say my battery benefits, which is the goal for all of us in the end. Stay cool, get to the end of the day. ;)
[Nexus 4 General] Flipz77:
By the way, here's a couple screens. Yes, it's mostly on wifi and some airplane mode, but I did use it throughout the day. I don't turn off connections if I need them ;) Love the Purity-Franco-Per App Modes combo, never getting below 18% on a full charge (no small charges throughout the day, I didn't buy a smartphone to be bound to a charger :D)
[Nexus 4 General] rondias18:

[Nexus 4 General] teachmeluv:
So? Anyway on that screen the phone is NOT charging and has that battery life left. My phone is always on (see attached trickster mod screenshot).

If you like it: "My battery on a modified stock kernel (if i would not charge it during the day)"
[Nexus 4 General] migueldbr:
that gives us no relevant information...where is the screen on time?
[Nexus 4 General] FormerSlacker:
Because even on stock you can get 6+ hours easy on Wi-Fi with low brightness if you avoid battery hogging apps like Chrome/FF or pretty much any browser, it just depends on how you use it.
[Nexus 4 General] Almayce:
Okay then which browser should I use to save some battery?
[Nexus 4 General] FormerSlacker:
Opera mini is great on battery but limited in a lot of ways. The stock AOSP was good but now that they removed the efficent but older webview from kitkat there really is no good fully featured browser battery wise.

Opera was better as well but now they've gone to a Chrome backend so there really is no option.
[Nexus 4 General] Almayce:
This kinda sucks though. What about the CM browser on market? I mostly use my browser to read articles, check up on fb and that's basically it. I rarely play a video on YouTube.
[Nexus 4 General] FormerSlacker:
Basically if it's using Kitkat's webview (based on Chromium 33?) it's going to murder the battery.
[Nexus 4 General] rondias18:
