i'm wondering if google now monitoring location is a battery hog...

75% right now

4hr 13m on battery

screen 36%

maps - 14% (wtf?)

android os - 11%

android system 7%

wifi - 7%

cell standby 7%

phone idle 7%

All I ask is for a device to make it through a whole day. So far the n4 barely does it.... I relaly hope battery improves because its just o-k.
[Nexus 4 General] richteralan:
Turn off you GPS. You don't need them 24/7.
[Nexus 4 General] dale_cooper:
Agree, but I had it on my one S and didn't have battery issues....

I personally feel all of this can be fixed by software tweaking. The phone has a decent size battery - it should be better than we're seeing. Needless to say I turned GPS off.
[Nexus 4 General] ock:
Yes, could be the location reporting feature in Google Maps. It caused a noticeable decrease in idle drain

When to charge a Lithium-ion battery?

Unlike nickel-cadmium and nickel-metal hydride rechargeable batteries, lithium-ion (Li-ion) rechargeable batteries have no memory effect, therefore, it is not necessary to fully discharge your battery before recharging. Actually, Li-ion batteries will generally last longer if you do not completely discharge them before recharging. For example, if you regularly recharge a Li-ion battery only after discharging it completely (known as "100% Depth of Discharge"), you can generally expect to obtain between 300 and 500 charge-discharge cycles. However, if you recharge the battery after only a partial discharge, e.g., 50%, you can expect to achieve over 500 charge-discharge cycles; even more if you use a lower depth of discharge, such as 20%. Therefore, you can effectively recharge Li-ion batteries even if they have only been discharged for a short time.

To maintain a healthy battery, follow the device manufacturer's charging recommendations, and do not expose the battery to temperatures above 60 degrees C (140 degrees F).

Pouch cell: A battery in which the typical metallic cylinder and glass-to-metal electrical feed-through is replaced with a flexible, heat-sealable foil package.

Protection circuit: Circuit built into the battery pack to maintain the safety of the battery and equipment in case of improper handling.
[Nexus 4 General] stangy:
Sounds like you have a bad app running. Factory reset and dont install any additional apps. Does it still get hot idle?
[Nexus 4 General] yfbc:
I'll try that later can someone tell me the running temp of your Nexus battery?

Mine seems to be 33 - 36 degrees celcius

1D 4H on Battery

I got 1 Day and 4 Hours on a full single charge.

On screen time was 2hrs and 45 minutes. (about 30 minutes was you tube and another 45 minutes was angry birds)

Data was off only about 4 hours

Auto-Brightness on the whole time.

** Piks or it didn't happen??? Give me 25 minutes.
[Nexus 4 General] procoder:
compare you note 2 with nexus 4 battery?? and otherwise difference between both devices..
[Nexus 4 General] Esteef:
I've noticed that anything that consumes data will make the phone hot.

I was downloading a torrent and the phone got really warm.
[Nexus 4 General] Luxferro:
Torrents are a HEAVY load on your wireless, or any lan connection, router, ect.
[Nexus 4 General] marshalex:
Down to 50% on mine 10h 15m 23s, screen time of 1h 9m 55s. Bluetooth music streaming for 2 hours, browsing Facebook, push emails and eBay alerts. Wifi gps all on. Good signal at work. Installed a couple of apps as well. Doesn't seem to bad to me!
[Nexus 4 General] barondebxl:
My secret about satisfying battery life? Use the phone like you want and charge it when you need to do so.
[Nexus 4 General] dale_cooper:
That seems good for being off 10 hrs, however I'm surprised your screen time is only 1 hr 9m while doing all of that. I'm at

56% left

5hr 57 min on battery

screen time - 1h 12m

bleh :(
[Nexus 4 General] yfbc:
Mine died just after 9 hours, my lumia 800 lasts this long normally and I do much more with that.

I don't want to have to return/exchange this, I will try a factory reset but I don't have high hopes tbh. Still worried that my battery runs at 33°c as standard :-\
[Nexus 4 General] Stretlow:
That's all well and good but what about those times when you're away from a charger for an extended period of time.
[Nexus 4 General] ctfrommn:
Screen on time?
[Nexus 4 General] yfbc:
2hr 24mins 17seconds

Auto brightness.
[Nexus 4 General] dcarpenter85:
I can get about 4 hours screen on time on a full charge. I suppose I should be satisfied with this but I am used to getting much, much more on my Atrix 4g. I'll learn to live with it!
[Nexus 4 General] jonmorris:
I'd say games first, but perhaps depending on the type of game (3D etc) and then browsing over 3G.

Lastly, watching a movie. Decoding a video is no trouble for the processor - just don't have the brightness too high!

I've installed the Qualcomm battery app but must wait a day or two before it begins to work!
[Nexus 4 General] shadehh:
I installed it Zoo. I have a question. Do you know if that APP is created by qualcomm them self?

P.s: my screen time: I'm on my second charge cycle, got this phone two days ago and I absolutely love it. Only nexus for me in future. Really adore the experience.

Battery life is great for me - maybe it is cause I'm coming from a one x (which broke - I like to think that the screen accidentally fell due to the hatred i had towards that phone)
[Nexus 4 General] motoridersd:
My battery life did not change after the 4.2.2 update, but it has always been pretty meh. It's very similar to what my iPhone 4S gave me, but since I consider myself a power user, I have not really thought this was something that could be improved. I don't think I ever get 2 hours of screen time, and my battery monitors always tell me that screen is the biggest drain. Today I installed a third party auto brightness program (trying out Screen Brightness today). I've always felt the stock auto brightness set it too high in most settings, so I'm hoping this new app will help reduce my screen drain without having to have the brightness at low all the time.

Here are my stats for today:

This is pretty typical, and maybe a little lower than usual. I always have to recharge at work at some point, and while I'm at work I don't use the phone that much.

I think my most battery draining activities are push notifications. I have 3 Gmail accounts, 1 ActiveSync, Tweetings, Facebook, Instagram all pushing updates. Tweetings and the Gmail accounts are probably the most active. I also have Google Now enabled and Bluetooth is always on. I do SMS during the day, but a lot of them are done through Mighty Text on the computer. I did have Chomp SMS turn the screen on with incoming SMS. I turned that off yesterday and it doesn't seem to have made much difference. I have Facebook sync disabled. I have Dropbox Camera Uploads turned on on WiFi.

Since I believe push notifications are the most draining, why don't I see that in the battery monitors? The CPU time for the Android System is very low.

Mediaserver is used because I stream Spotify through bluetooth at home and during the drive home (today it was using Podcast Addict).

Does this seem normal as a power user? Or are other power users getting much better battery life than this?

Running latest cm nightly and faux with a 100uv. Cant complain.

Edit: i have been on wifi. Some browsing, facebook and whats app.
[Nexus 4 General] Eradorius:
Battery life is great on this phone. Mainly browsing, music, YouTube (HD), bit of gaming.

[Nexus 4 General] Liam0o:
Battery life is quite good on the N4, a days use with 4 hours screen on time is enough for me personally

Also coming from a One X where i had to disable 2 cores and UV by a large margin to get a day of moderate use
[Nexus 4 General] KtMack23:
I'm getting terrible battery life. I'm on a cm version of 4.2.2 with Franco. I lost 10% of battery life on 2 hrs of standby on WiFi.
[Nexus 4 General] smanthrav:
Mine isn't great but its fairly satisfactory. I'm at 21 hrs of standby and 2 hrs of screen time...got 47% battery remaining.
[Nexus 4 General] QUIETLYloud:
Well coming from the galaxy s4g and I have NO complaints concerning battery I'm completely stock in every way.

**Note I was on Wi-Fi all day today but I down loaded and watched a few you tube hi-def movies
[Nexus 4 General] SnowBeer:
I updated to 4.2.2 and noticed the majority of my battery being Google services. Is this Google now? I'm thinking of trying with now turned off.
[Nexus 4 General] scream4cheese:
Everyone should try this app:

https://play.google.com/store/apps/...sMSwxLDIxMiwiY29tLm9hc2lzZmVuZy5ncmVlbmlmeSJd

This app will keep applications from running in the background that will not let the phone go into deep sleep mode.

Here's some more info from the developer himself:

http://xdaforums.com/showthread.php?t=2155737

I've been using it for a few hours and it's been great.

Check it out.
[Nexus 4 General] bgaccord:
i had good battery life on cm10.1 getting about 3 1/2 screen time.now i went to stock 4.2.2 stock kernel and only getting 2hrs if lucky

on hspa+ all day , messaging ,checking email ,browser,and like 3 youtube videos .

what are u guys doing to get 4hrs+ screen time ? i do 5min candy crusher gaming thats it.
[Nexus 4 General] shadehh:
I got 4 hour screen time yesterday with 10%, battery left. I manually set my brightness levels , usually around the 20% mark . I would say I used WiFi for 30% of the time and the other I used 3g. Today I'm on WiFi, 33 minute screen on and 90% battery.

I only switch on WiFi/3g when needed, otherwise I leave it switched off.

Edit: my main usage is browsing, whatsapp, gmail and text messaging. Sometimes I use one more the other time less. I'm fairly happy with my battery life. You heard that old dead HTC one x? SATISFIED. (sorry, bashing my crappy one x makes me feel better)
[Nexus 4 General] azik:
Folks, does your nexus charging takes a while too? I've been using the charger that came with the phone for the past two days and it seems it takes hours to get fully charged.
[Nexus 4 General] gandharva:
Yes, charging is very slow, but you could install a custom kernel like faux and enable fastcharge. This will speed up charging significantly.
[Nexus 4 General] lowtje:
100% is just cosmatic. The real count is from +- 92%
[Nexus 4 General] azik:
I'm new to Android and want to keep its virginity for a while LOL.

Wouldn't enabling fast charge be bad for the battery long term?
[Nexus 4 General] lowtje:
No it will not harm your battery. Fastcharge only works with charging on usb or car charger. Turns off the services to make charging as fast as on a/c
[Nexus 4 General] cobyman7035:
2hrs I'd chuck the phone lol.

Use Franco kernel. Turn off all stuff like NFC. Google sync. 20% brightness. Under volt. Use governor settings... Should get 5 yes easily

[Nexus 4 General] davidsteele1975:
Left alone, my Nexus 4 uses noticeably less power running 4.2.2... I'm happier for it!
[Nexus 4 General] -Asskicker-:
It really depends on how you use your phone. I mostly use my phone on the train to / from work so I'm glad if I get 4 hours screen on time!

Having 3G on and it constantly switching towers is very draining for battery life.

That being said, how is the battery life on the latest CM's?
[Nexus 4 General] razball:
I don't know what is happening but I've stayed at 100% for 10 minutes and an hour stand by the only change is downloading Qualcomm guru app I would suggest it
[Nexus 4 General] razball:
Just now went down 2% but screen on is 16 minutes. And trust me I've never come close to that
[Nexus 4 General] jonmorris:
For those that haven't rooted, I'd suggest giving the new Qualcomm app a try; although it takes two days to do anything - so I haven't been told what improvements it is going to make; https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app

The principle is quite simple; it will stop background syncing on apps when the phone thinks you don't need them, and also do it based on where you are (controlling Wi-Fi etc). It can do it on an app-by-app basis. [Sure, there are other apps but this one seems particularly simple].

My only fear is that when I turn off Wi-Fi, the N4 battery can drain far quicker - so that might not be a good thing.

Definitely in standby, with the phone in deep sleep way more than it was before - but every now and then it seems to suddenly get really hot and the battery obviously takes a battering, all while in standby mode. I haven't a clue what causes that; is it a wayward app or something with the OS?

Either way, my main fear (which is what makes me nervous when using the N4 away from home/mains charging) is that the battery life can be unpredictable. And when using mobile data, it always drains far quicker too.

In normal use, I don't see any real difference. Still, by tomorrow I'll hopefully be seeing what the Qualcomm Snapdragon BatteryGuru can do!
[Nexus 4 General] azik:
So basically it wouldn't matter if I use the charger or USB ?
[Nexus 4 General] kennynguyen20:
Getting so so much better with 4.2.2 than 4.2.1, no more wakelocks, i can easily get 4 hours on screen time. very very happy.
[Nexus 4 General] jonmorris:
The Nexus 4 is designed for quick charging (with V1.0). V2.0 for Snapdragon 800 is significantly faster still.

http://www.qualcomm.com/media/blog/...-charge-10-less-time-charging-more-time-doing

So, by rights, charging should be quick. Of course, it all depends on the amps from the PSU being used.. some are much higher than others.
[Nexus 4 General] starfarer:
Promised myself not to check this thread and drool over someone's 5+ hr screen time but can't help myself :(. Anyway can ppl please post the loss % in 15 minutes of browsing or reading books/PDF ? Thanks
[Nexus 4 General] azrash:
if you are reading an ebook, if should have among the lowest power consumption with the screen on. I am not sure about PDF though, they might be a bit resource intensive since some of them are heavy on images.

I am using epub format with Aldiko and I get a much longer SOT when I am just reading ebooks.

[Nexus 4 General] starfarer:
Cheers. OK so what about browsing or XDA app?
[Nexus 4 General] lowtje:
Yes :) but on usb you won't be able to use mass storage etc. until you turn fastcharge off

I have to say I am a bit surprised. Passed the 5h Mark (3g/WiFi).

I got my N4 on Monday and my battery seems to be calibrated wrong. My phone jumps down to 1% fairly quickly (well not that quick... after about 15 hours with 2.5 hours screen on time) but will then stay on 1% for 2-3 hours before the phone shuts itself off.

I have done this twice now.

Last night I charged from empty to full with the phone turned off to see if that helps.

Now I am on 95% after 2.5 hours with little usage, but 3g on.

All stock 4.2.2 , screen brightness set on auto, wifi on for more than half the duration( only turn it off when i sleep), lost 2% overnight ( i slept for 10 hours :D ).

More than decent battery life if you ask me. I never had "problems" with the battery life .. Do I have lower expectations than everyone ?? Or is it that some people are just never satisfied with what they have ?

6hrs screen on with 24 hour of single charge thats awesome.

But can anyone tell me how long does it last in videos? Gsm arena said 4hrs

Hey,i'm getting my Nexus 4 in a copule of days.

I have read that the the charger that comes with the nexus 4 is not good,because it put outs too much current and it causes all sorts of problems,so i'm kind of worried and don't know if to use it or buy a Samsung charger that put outs less current.

Please help!:fingers-crossed:
[Nexus 4 General] jonmorris:
Took much? The phone will only draw what it needs surely?
[Nexus 4 General] shadehh:
Don't worry. The nexus 4 has a power supply attachment slot. I simply took the 650watt from my PC and connected to my phone. Charge in 5 min from 1%to 4600%.
[Nexus 4 General] Younggun123:
I think someone has been feeding you wrong information. Charger is just what it should be. From what I've been able to surmise hw. Ver. 10 had some charging issue with some units (inc. Myself). HW ver. 11 is much, much better.
[Nexus 4 General] edvedder:
Yes but i read that it causes the phone to gethotter while charging because of the high current(not sure of the exact terminology,sorry)and that it drains faster because it charges faster,and i think this is true,becaue i have a quick charge aa battery charger that charges the batteries in 30 minutes,but they also drain faster,but i'm not sure if it applies to phone batteries also...

I'm running completely stock 4.2.2 and when I'm working, I can now expect to see a couple of days to a charge with a couple of hours of screen on time. I am happy with this because I have Google Now on, Location Services set up, my Gmail set to AutoSync (including Google Reader), plus I keep the modem and WiFi turned on. Half the time my brightness is at minimum, the rest of the time it's on Auto. My daily commute is about 90 miles in total and I'll often stream music over WiFi / Bluetooth. Yeah I'd expect to see five hours if I was at home all day (minimum brightness, WiFi and not travelling)...
