[Nexus 4 General] Android Boss:
-> I used Dophin Browser and Google Currents for approx. 5 hours!

There are 2 main things which make battery life better:

1. get a clean installation of 4.2.2 (do not update any OTAs, see my previous post)

2. Deactivate syncronisation, go to manually sync.

I deactivated sync after I bought my phone. If your apps always want to sync the phone can't get much "deep sleep" and battery drain raises. This is the reason why my battery drain over night (7h) is only 10%, because it is in deep sleep!

And after reinstallation/reflashing the stock rom 4.2.2 I nearly doubled battery time.

I think with sync on I should get screen times of ~5 h (I didn't try)

Ok. I'm trying naked browser to see if Chrome is the problem. I done everything do you suggest.
[Nexus 4 General] nick34609:
Chrome was a battery killer for me when I had it installed.
[Nexus 4 General] undercover:
So is it proven to work?

R: The great battery impression thread

Only for users with many app installed, I think.
[Nexus 4 General] tye_time:
I'm on my second charge with my nexus 4 and these are my results now - could have probably got to the 7 hour screen on time if I let it discharge some more! :p

Once the 4.2.2 update was installed I did a factory reset and also cleared the cache (not sure if that helped or not though)

Amazing!!! How about ur brightness?
[Nexus 4 General] funkyblue04:
So there is no point buying this phone. Sigh when will we get a decent stock phone with at least 8 hours on screen time?

I can at least swap batteries with my GN.
[Nexus 4 General] davidsteele1975:
I'm curious; can you list the handsets that give eight hours of screen on battery life right out of the box?? Galaxy Note II, RAZR MAXX, and..?
[Nexus 4 General] funkyblue04:
That is about it. No one seems to want to focus on battery life. It is all bigger and faster with crap batteries.

You should not have to try and conserve battery life.
[Nexus 4 General] davidsteele1975:
Take a look at Motorola; they've said that their focus is battery life. In the UK at least, products such as the iRAZR with a 2,000 mAh battery and relatively lightweight internals goes a long way. Not ideal, sure, but getting there.

However, eight hours of screen on time is (for most people) way more than they need in one day. One day to a charge is the compromise that manufacturers are aiming for, together with everything else that the generic average consumer wants from his or her device.

I don't have to make a compromise with most smartphones, most of the time, so I guess I'm average enough. I do understand what you mean, but the number of people who'll take an inch-thick smartphone that'll give them three days to a charge is very limited compared with the number of relatively light users happy to get a day and put it on charge when they get to their workplace the next day if they forget to put it on the charger that night. :silly:

Really, I'd like a smartphone with the longevity of my Palm IIIxe. Two weeks between fresh rechargeable batteries with a lot of use.
[Nexus 4 General] funkyblue04:
The thing is most phones do not last a full day when you play games, make calls, browse, use maps and apps etc.
[Nexus 4 General] davidsteele1975:
Yes. Most people don't use their handsets as much as most XDA members do. :)
[Nexus 4 General] funkyblue04:
I would argue that is not the case. Mos people have this issue.
[Nexus 4 General] davidsteele1975:
I guess we'll have to disagree. In 2012, battery life turned a corner and most clients I see at my workplace (I'm a retail technical specialist for one of the UK networks; day in, day out I help people with their issues on smartphones and similar technology) there are way fewer battery life issues compared with 2011 devices. Partially, this is because people are lighter users, partially because they still have chargers and charging accessories from their older devices. And partially because 2012's handsets are more efficient (helped by greater WiFi and network signal in and around where people work).

Now, amongst my Android-owning friends, it's a different story. They've either adopted the Note II, RAZR MAXX or have developed a decent infrastructure of chargers. :)
[Nexus 4 General] shadehh:
Is my chrome browser consumption a bit higher than it should be?
[Nexus 4 General] davwman:
Chrome is a huge battery hog. I use the stock browser and I'd be lucky to see 4% use on it.
[Nexus 4 General] shadehh:
Can it be found in the play store. ?

[Nexus 4 General] shadehh:
I was assuming he meant the browser prior to chrome. It has (chrome beta +chrome) more usage than my screen that is nuts. Could have easily gotten an hour of screen time out of that insane usage
[Nexus 4 General] f.us:
I am, in general, very happy with my nexus 4 and the battery life. As long as I can use it troughout the day, everything's fine.

See the attached files for instance (usage two days ago).

But today... I was a little suprised to see my battery down to 47% after the use of navigation for 1h 20min.

Prior to using navigation, my device was idle for (most of the) 3 hours.

Other than leaving it idle, I checked my twitter timeline once and synced my weekly backup (today arround 124MB) to the cloud using Titanium.

The backup was performed while the device was on the charger. Just the syncing was on battery.

Since I am not usually navigating all the time or for hours, there is nothing to complain. Just checking if this normal.

What got me to posting this is a warning notification from GSam Battery Monitor.

Stating my device, well, the battery temperature, would be to high. It reported 36°C (arround 97°F).

It was warm, but I wouldn't consider it to be hot or be alerted by it. Or should I be alerted?
[Nexus 4 General] davidsteele1975:
Yeah, navigation is quite hard on the device. The GPS chip uses a lot of juice, plus you're using the screen on and the data network, too. Not to mention some processor power.

As for the heat, I'd not consider that to be a dangerous temperature. I'd expect it to sit at or slightly above that temperature for periods of the day if the device is carried in a pocket.
[Nexus 4 General] tye_time:
I had auto brightness on the whole time.

[Nexus 4 General] jonathan3579:
I'm super impressed with how 4.2.2 has treated my battery. There's been one day where I got around 15hrs off charger and nearly 6hrs screen on time at 1%. I'd upload the screenshot but this app sucks ass. :rolleyes:
[Nexus 4 General] mpttrung:
Great. Will try to factory restore soon to see what gonna happen :d
[Nexus 4 General] drakenabarion:
I was pleased with my battery today. Mostly gtalk, Facebook messaging, xda app, some browsing, no games, benchmarks or photos today.

Yesterday I was playing around with photosphere for a bit getting some practice and it went from about 70% to 20% within an hour. Well let's be honest, cameras are battery intensive so no surprise there.
[Nexus 4 General] Zorachus:
My new, two day old Nexus 4, running Xylon ROM 4.2.2 and Matrix kernel v7.0. Plus the killer new app "Greenify *ROOT*" , helps certain apps hibernate. Battery life, so far is pretty darn good on this phone, blows away my old Verizon Galaxy Nexus. We shall see what a workday ahead brings.

Only had the N4 two days, both days got 5+ hours On Screen time.
[Nexus 4 General] cobyman7035:
Is that 3g only?
[Nexus 4 General] twowheeler:
Is it possible that battery life will become better over time? I am on my 3rd charge now. Does it need some time to learn from the battery? Had this with my old phone
[Nexus 4 General] davidsteele1975:
In my experience, yes it will. Absolutely. I believe there are three factors at work here as well.

One is that as we get used to a device, we tinker with it less and use it more. So that means a little less screen on time, which helps.

Two is that the battery becomes conditioned, so it holds more energy.

And third is my airy Princess Castle idea that when we travel, the device either caches the cloud-sourced WiFi hotspot location database, or anticipates where we are and this saves power.

For my own device, point one is absolutely the case. Points two and three happened at the same time, but after two weeks my battery was meaningfully higher when I'd arrive back from work than at the start. Rather than being at 30% it was at 50%.

Of course, our habits, commutes, networks and similar are all different. I use Google Now and location services enabled, which will enable GPS during my 44 miles commute presumably as it doesn't know where I am and can only see one mast. Maybe.
[Nexus 4 General] twowheeler:
Ok, I think you're right. Also explains why some are getting more/less battery life than others. I did just one total discharge. First 15% are gone pretty fast, looks like it's getting settled right now. So I'll wait a few days before getting a good readout.
[Nexus 4 General] davidsteele1975:
I did keep a detailed log of screen on time, 3G data and WiFi data for the first fortnight because I'm geeky like that. But even though we could all do the same thing, we're on different carriers, using different frequencies, with different accounts in different locations.

I likened it to a car. The first few weeks (months) the engine isn't bedded in. Then it is. Then it starts to wear out. The battery in the Nexus 4 should take longer to wear out, so maybe it takes longer to be properly conditioned?
[Nexus 4 General] davwman:
Well this is certainly different mainly 3g with about a 1/2 hour WiFi. Streaming Pandora for almost 2 hours screen on 2 hours and only 30% gone. Would normally be around 90 minutes screen time with about 60% left. Running latest xylon with new radio and boot loader and trinity 97
[Nexus 4 General] davwman:
At 20% left, I'm currently sitting at 5 hours screen time and about four hours streaming Pandora, Facebook via browser, xda, download of new vanir ROM, etc etc. And this is about what my piece of crap no signal having, dull screen HTC one s used to get. I'd say this qualifies as excellent battery life considering the specs

suspend_backoff

Hi,

I am running 4.2.2 stock kernel+rom, rooted.

after the update my battery life went really bad after a couple of days. For some reason the first days were fine.

To my knowledge I have not added any new apps.

I have tracked down the culprit to be "suspend_backoff"

BBS shows "suspend_backoff" at 45% before the update it was at 4-5.

I've been searching the interwebs and xda but no solotion yet.

Turning Google Now and Location services off doesn't change anything.

The tilt scroll setting in chrome is turned off.

Does anyone have any advice?

My third full day with my new Nexus 4, again the same. 15 hours total off charger, with 4h55m On Screen time. Battery @ 20% left.

On WiFi maybe 4 hours today, rest at work or in car, no WiFi.

I have been getting around 15h - 16h total off charger, with approx 5h On Screen time, before battery gets to red alert 14%
[Nexus 4 General] barondebxl:
Then what's the point? What's the point of reaching 12 hours of screen time on this phone ( which is not possible unless you use your phone to swipe through the home screens) if you're limiting your normal usage? Just use the phone you normally do. Some people only need 2:30 hours on screen time with 12 hours off charge to call it good battery life. Some need 4 hours of on screen time with 16 hours of charge, it depends of the user. I'm happy with 3:30 hours of on screen time (heavy use) with 14 hours off charge.

How can you make your idle??

I notice that you hardly consume any battery while your phone is idle (screen off). lt looks like the stride line. are you completely turn off your 3G and use WIFI only? or you are using some software like Juicedenfender to shut down mobile data connection while screen off? please
[Nexus 4 General] Gr€€n:
I noticed by my own use, that even with wifi and/or 3G on the phone barely consume anything while idle IF if doesn't have some weirds wakelocks that'll consume its battery.

Some nights (8-10h) I only loose 1% but most of the time (due to wakelocks) the battery comsumption in idle mode is awful.

After reflash stock do you reset in android or recovery mode?

My Nexus 4 done 6 hours sot, after factory reset in settings->privacy "android os" drain battery....very strange.
[Nexus 4 General] Nathtech:
So I'm thinking of reflashing stock via fast boot. But is it worth factory resetting first to see if that makes a difference? I'm on PA.
[Nexus 4 General] davwman:
What problems are you having? Ever since updating radio boot loader and running 4.2.2 Roms with trinity 97 I've seen 5-6 hours screen time with hard use and streaming. If you have the time its easy enough to fastboot stock and reinstall recovery and ROM of choice. It is a nexus afterall;)
[Nexus 4 General] Nathtech:
I get really poor battery. Around 2 hours screen on (just). I've heard flashing a stock image will help?
[Nexus 4 General] davwman:
It depends on usage, sync, signal, etc. Try it as long as you know how. I seriously will suggest if you flash another ROM/kernel try xylon or aokp with trinity. I'm waiting on rasbean to go 4.2.2. At this point off charger since 5 am this morning and I'm at 35% with 4 1/2 hours screen time and its 12:30 pm now. My 3g and WiFi is 75/25 and I stream Pandora roughly 6 hours a day. One email sync via email not gmail. 1% of my day is games and I check Facebook via mobile website receiving notifications via SMS, and xda a lot via tapa talk. I manage airplane mode manually because I work in an area with crap service because I work underground.
[Nexus 4 General] Nathtech:
Well I don't play any games, all I use is gmail, chrome, tapa talk and an app called Palringo. Plus habit of YouTube usage. I'm on WiFi most of the time and all sync is off except gmail. I'm using PA with Franco currently. Am I getting good battery for my usage?
[Nexus 4 General] davwman:
Should be better and chrome is a huge battery hog. I use stock browser a lot and usage is always near 4%. Chrome always sat at the top consuming battery. I would do a fresh flash
[Nexus 4 General] styckx:
2hrs?? Total SOT?? That's terrible if you are truly just doing normal casual use things. 3-4hr SOT is about average for this phone under "normal" circumstances. You either have a widget which is calling home way to often or an app that isn't letting your phone sleep at all.

This is my phone so far today.. Some phone calls, Google Nav for 10 minutes, Chrome, Tapatalk consistently throughout the day. No gaming.. I'm also a habitual app closer.. When putting your phone to sleep tap the key to the right of the home button. Then close everything by tapping icon in the upper right. You should get in the habit of cleaning that out just as you would your notification pulldown. With 2GB of RAM onboard more apps tend to stay in memory then a phone with 1GB (most of them).. Kill em.. No need for them to stay active in memory..
[Nexus 4 General] Nathtech:
I do that already ;) And the only widget I use is dash clock widget. Anything wrong with that?
[Nexus 4 General] asb123:
I think my battery problems are directly linked to my signal strength, which oddly enough, seems to be linked to my screen being on! O.o

I live in downtown Montreal and am on rogers/fido so I should have excellent signal strength. But for the week or so that I've had my phone, I have noticed that I am getting terrible signal. And the data even dies out for a second or so sometimes.

Looking at the battery stats, for some reason, the signal is horrible exactly when the screen is on, but great while the screen is off.

I am running stock 4.2.2 rooted with trinity. But have had this problem even when I was full stock :s
[Nexus 4 General] styckx:
From my experience with Dashclock; it seems to be really well written and behaves itself. :)

I gotta ask out of curosity sakes. Is anyone able to get their battery to completely flatline while sleeping? I'm sitting on CM 10.1 (waiting for Rascarlo to get Rasbean to 4.2.2) and no matter the kernel I just can't get a flat line battery while sleeping. The only widget I use is HD Widgets w/ a 8hrs refresh interval and set to not use GPS and not to do updates while the screen is off. There just always seems to be a slow progression downwards no matter what. Are the radios in these things power hungry?

Here is an example from my current battery run.. I outlined two areas where the screen was off for a decent amount of time.. And it's like nothing even change.. Same slow draw downwards.
[Nexus 4 General] rest0ck:
I'm currently at the Enhanced Stock Kernel from harsh and I pretty much like it but I don't get as good results as some people here.

I tried matrix but once I switched back to another kernel my phone got sooo slow and nothing solves this except for reflashing the whole rom.

And now I'm afraid to flash it again :D

So which kernel would you recommend with stock 4.2.2 for battery? :)
[Nexus 4 General] EvoXOhio:
when you switch from one third party kernel to another, you need to first reflash your rom (no wipe) and then flash the new kernel. I always do that. I forgot to do it once and experienced the same slowness as you.
[Nexus 4 General] styckx:
That's actually unnecessary. Re-Flashing the ROM... The most you have to do when switching kernels is wipe dalvik/cache and that's a huge maybe and only if one kernel is using a different ramdisk than the one your flashing. 99% of the time you need to do nothing when flashing a new kernel.
[Nexus 4 General] Nathtech:
Ok thanks. Will be trying tomorrow. If it still doesnt satisfy me il go about reflashing stock via fastboot.

Was an iPhone, iPhone 3GS and iPhone 4S but switched to the Nexus 4 last week and am loving it.

Pleased with battery life as well. I did the research before I got the phone and have tried to set up sync the way I want etc. On my hour commute in the morning on public transport, I'd listen to Music, use apps etc. During the day I'd be using email. Twitter and more.

Will it work just the same if i use the n4 toolkit by mskip to do it? It seems simpler that way.
[Nexus 4 General] matt1733:
flashing the rom again is not needed just make sure if you using a third party kernel it doesnt have modified ram disk and if does just reflash the stock one before
