What do you think? Is it normal while sleeping (9 h.) to drop 14%?

What can be improved?

Should I disable locations?

Generally normal readings?
[Nexus 4 General] azrash:
to be honest, it is hard to give you advise based on screenshots. Why don't you take an idle dump and post it in the BBS thread instead? On idle, i get around 0.5-0.7%/hour drain with full sync on, location are on too.

With my new RMA hw ver. 11, I am getting about 6 hours of screen time on average, 90% on WiFi. Quite a bit better then my old one which was about 4 hours. BTW, nothing wrong with my old one ... the power brick was the problem.

Running 100% stock.
[Nexus 4 General] Bluewall:
6 hours screen on but what's the time from unplugged ? :P
[Nexus 4 General] Younggun123:
About 15 hours total on time with 6 hours screen. That's medium use for me. Mostly email, texting, surfing, an hour for games, music through songza a for about an hour. 90% on WiFi.

I know a lot of people hate on it, but the app Juice defender works really well for me.

Unfortunately my network has no 2G service which would make it even better, but I see massive battery savings.

The other good thing is the data connects very quickly on the N4 when you turn the screen on - this was an issue for me on older devices and versions.

The downside is obvioulsy you dont get 'true' push data notifications , but I can live with 15 minute delayed emails.
[Nexus 4 General] Younggun123:
Half way through. You do the math. Slow use day. Almost all texting, email, and surfing.
[Nexus 4 General] WiseManWhite:
My phone would be at 20% if I that. What in the world am I doing wrong?

Even this morning, all I did was respond to a few emails and surf the web a bit. Dropped to 20% in 1 hr 18 min with 32 minutes of when on time.

What HW very are you on. When I went from 10 to 11 on my RMA, I found it made a big difference. Went from 4 hours of screen time to 6 on avg. From what I understand I'm not the only one to notice the improvement. I'm to chicken to root and run custom kernels. Looking forward to Android 4.2.2 for hopefully even better battery life.

[Nexus 4 General] gguy1:
Just out of curiosity What version of hardware are you running?...because on average so far I've only gotten 2 hours on 4g with T-Mobile,and 4 hours on Wi-Fi and I usually freeze things I don't need until I need them such as Facebook, maps, Google search and Google + most other things a keep normal though, also I keep GPS off until I use maps, and my screen on 100 percent brightness... My battery life stays fairly the same on whatever version of Franco kernel I use but typically that's the kernel I run.
[Nexus 4 General] StrizzMatik:
Rev. 11 is my hardware. No GPS, sync off, about 10-20% brightness for me. I'm on AT&T, service is average at my house but perfect at my job
[Nexus 4 General] Younggun123:
Finished my full charge. Here's where I ended up. This was with low use on stock kernel. Normally I stream music through songza which brings my screen to about 6 hours on ave. Most of the use on this charge was email, texting, surfing
[Nexus 4 General] WiseManWhite:
I'm on HW 11 :-/ on T-Mobile. Maybe I'll try a new kernel. I'm using the stock one at the moment.
[Nexus 4 General] btbaker2008:
Can you guys let me know if something is wrong with my phone? I've never been able to get 2+ hours of screen on time. Every time I browse the web my phone gets really hot. I don't use the phone that much throughout the day and my office has pretty good cell service. I'm running the plates AOKP with the newest Faux kernel with an underclock and all the settings he suggests for extra battery life.

[Nexus 4 General] jvbferrer:
I got to the conclusion that my Nexus lasts around 4-5 hours with screen on. After an intensive following of each charging cycle, I see that it's ~1'2 screen hours per 25% of battery. No location tracking, Google Now off, sync on, auto brightness, 3G on, stock rom and franco kernel r53.

It perfectly gets to 2 day with short but intensive use.

Not sure if this has been mentioned, but I had a screen lock app installed and was getting pretty bad battery life (1.5hrs screen time and 30% battery remaining, good cell signal strength, etc.).

[Nexus 4 General] Kenichi:
I personally used Faux's Kernel and his specified app for his kernel, and I haven't been able to push more than 3 hours of screen time with his battery saving settings. I've come to the conclusion that if you configure more with your CPU/Phone such as UV, Min/Max CPU, and Eco Mode. You end up with worse battery life. So I disabled the whole app out of curiosity, and my battery held up for a longer duration than with his "battery saving" settings. I'd also suggest to move over to Franco's R53 Kernel as seems to be doing great for me. No configuration is needed in order to produce a longevity battery life. I'm able to produce about 4 hours and 30 minutes of screen time with only WiFi and Bluetooth turned off. Also, it may be where you go, if your signal drops all the time such as where I go for class, it does greatly reduce your battery longevity.

First day with my rev 11 and matrix 6.0
[Nexus 4 General] greyhulk:
I received my Nexus Friday. My impressions are this:

1) It does not use much battery at idle. I left it sitting out overnight for 7 hours and it only lost around 2%. This is great and much better than I was expecting.

2) However, when I USE the phone, it burns through battery faster than any other phone I have had.

This is okay and works with my usage patterns (I have a tablet and don't use my phone a lot during the day), but I wouldn't complain if it was better. Since my battery has only been through a few charge cycles, it's not conditioned anyway, so this probably isn't as good as it gets. Still, I'm pretty impressed thus far. Based on what I had been reading, I was expecting something awful in the battery life department.

More texting

Hour and half after I've set off I should be at uni will of been playing the entire time. But for the last half hour am on a train and the signal is constantly changing

When lecture starts if am really bored I switch to the wifi and mess about on a game or two and check some web pages and before I know it I have a bit of battery left I have to preserve for the journey home to listen to music

[Nexus 4 General] davidsteele1975:
I'm finding that my Nexus 4's battery life has noticeably improved over the last month. I've not changed my usage and I am using Google Now, Latitude and keep the 3G and WiFi radios on... So either the battery take several weeks to condition or Google Now is getting used to my routines and is less reliant on location data or services.
[Nexus 4 General] fredcorp6:
Is it normal to have such high "Android OS" and "Android System" percentages??
[Nexus 4 General] TrevSo:
If it's on standby a lot, and you have things on like Google Now and sync, then the OS can take a decent amount of battery. After sitting overnight, Android OS is now showing as using more battery then the screen on my Nexus 4.

I meant 4 hours on wifi. On 3G I'd be much worse. I'm going to give Franco kernel a shot. The irony is that I see more people on his kernel reporting outstanding battery life, but his kernels is one of the few that doesn't have the msm_hsic_hosts wakelock fix. So in theory the battery life of his kernel should suffer. But it doesn't. Time to try myself I guess.

I found myself doubting Franco's kernel too. I was trying to decide between his and Matrix for a long time... But after only getting 2-3 hours screen on time with the stock kernel, I decided to just give it a try hahaha nothing to lose but everything to gain! I chose not to go with Matrix because they're still undergoing testing with their 6.5 version the last time I checked.

I'm very surprised about my battery life as well though and thought that I should share my results right away in case someone was looking for some pretty nice longevity to their phone life. Good luck with your's! I hope you get 8 hours :good: :p

Charge your phone for 8 hrs than turn it off and keep charging for 1hr and turn on

this is mine, I wasn't really texting at all today which seems to of extended the life of it slightly. odd thing is i don't usually use quickoffice but today it kept itself in the background for quite some time till i forced closed it.

I did turn off just about everything when the battery hit 5% which seemed to extend the battery life by far lol, had plenty of time to read and ebook and listen to music on a very low brightness screen. I could probably get another hour out of it if I turn off stuff like mobile data and have low brightness and not text. but then I may as well not have it and just get a very old cheap nokia 3310 that can last for a long time on its battery for texting and ringing, and ofc snake.

I was getting good battery life for a while (easily a full day's worth) but it's lately gone steadily downhill. Only getting about 12 hours instead of 15+ with 3 hours screen time.

I get that to a degree. But I see people getting 50-60% better screen on than me. Manufacturing tolerances should t allow for that big of a discrepancy. Plus my chip is binned FASTER so in theory mine should under volt lower by default and have better battery life.
[Nexus 4 General] mysterioustko:
It all depends on how that screen time is being spent. If your screen time is being spent web browsing or streaming a movie, it will be significantly lower than a person who spent most of their screen time with it just sitting on so it can be high for a screenshot on a message board. My point is, keep in mind that actual usage is what will determine those types of variances.

I pray to the Flying Spaghetti Monster that people don't actually do that to get screenshots.

[Nexus 4 General] WibblyW:
Cell coverage can make an enormous difference

Maximum power output of a phone (in poor signal areas) can reach up to 2 watts (depending on the network type), which can drain your battery pretty fast! The phone will periodically transmit even if WiFi is on and active (to maintain a link with the cell tower for calls and txts/keep alive). If signal is very poor it will also keep retrying (at high power) to do this. Of course, if on 3G for data, if you happen to be in a poor signal area, there is quite a lot of high power tansmission from the phone.

So for comparison of battery life it's really necessary to state what the cell coverage is like, or battery life comparison is futile (in my opinion). Apps like GSam Battery monitor can give an indication of what the cell radio has been doing...

[Nexus 4 General] mysterioustko:
It's one of those cases of sad but true. Over the years here, I've seen so many different people put up screenshots of battery life, where if you pay attention to the details you'll see they basically did nothing with their phone besides turn the screen on. For some reason, there are some that see battery life screenshots as some sort of contest, and do some ridiculous things just to say "hey my battery lasted 24 hours", or "my screen time is 6 hours". All in all, my point is just that, one has to keep in mind that actual use of the device will cause battery life to vary between people. A person who actually uses their phone will have different battery life than someone who isn't doing much of anything.
[Nexus 4 General] ashkan_mc:
Two question guys

1) Do you think being rooted can affect battery life?

2) For me I think the auto brightness minimum is very high, how can I manage it? I mean I want to have a lower brightness when it is on auto brightness

Thanks
[Nexus 4 General] roswell782:
1) No

2) Try Screen filter (or another app)
[Nexus 4 General] mysterioustko:
Being rooted alone will not effect battery life. Remember all root does is give you additional permissions. Just having additional permissions will not make any change in battery life. That said, root apps that you install can possibly impact battery life (depending on what you install).
[Nexus 4 General] Younggun123:
Guess that really depends on what you define as some who "actually use their phone". As mine is work phone the vast majority of my usage is email, texting, and web browsing. Browsing will sometimes show up on the battery usage but not high on the list. Most likely 75% of my usage is texting and email and I they barely show up on the list. My exchange services is only showing up with 2% usage. Hell, my live wall paper has a higher usage at 3% currently. Bluetooth is on all day and it doesn't even show up on the list.The only other usage I really see a battery drain from is media server usage from playing music or streaming songsa.

So I'm guessing your "usage" is watching movies and gaming all day?
