Battery levels can vary by some degree, after heavy use you can see that the percentage is rising a little bit.

thanks
very nice thanks for all

Ok thanks !

You'll get a lot of replies from people saying they are delighted that with their battery life and claim that something is wrong with you.
From my experience with the Galaxy Nexus, I know that battery life with Android varies all over the place depending on how you use the phone and what apps you install. Install the wrong apps or get file corruption--that you can't pin down--the battery will drain just sitting there unused.
if you intend to keep the phone, I suggest getting a 12000mAH external power pack. Thanks Google for not allowing us to readily swap the battery.
Galaxy nexus 2 hour screen on time. Carried a spare battery. Nexus 4 close to 4 hours screen. I guess what I am saying is I can cope because I came from actual bad battery life.

My iphone 4s only lasts 8 hours with heavy use. Streaming movies, Sirius sat, games, web surfing.
This phone outlasts that so far with the same stuff.
But its terrible you should sell it.....
The battery has been so so for me. I'm hoping when a good kernel and Ron come it will be a lot better. I benefit from working in range of a outlet .

GS3 battery dominates the N4 battery even tho it has the same 2100mah size.
I guess the AMOLED >>> IPS LCD in terms of battery drainage.
Sucks! I guess the Nexus 4 battery life will be only slightly better than my One X =(
I personally love the threads where former galaxy note owners and droid razer maxx owners ***** about battery life.

I swear guys I normally use same apps and on Note2 I was able to get day and day and half with heavy use and teo days with light use..but this N4 just drains battery like theres no tomorrow. Esp browsing internet..youtube..and other stuff that pulls a lot of data... The only way I can save battery is it i put brightness to almost zero and turn off wifi and data completely. I have all the normal stuff syncing and not often...facebook pulls data every 2 hours and other apps as well. I really love this device but WHY WHY WHY Google/LG decided to have non removable battery. I RESPECT Samsung so much more because they give you removable and decent battery and also give you SD card option which I can live without but its nice to have. I guess you get what you pay for.

GS3 most certainly does not dominate....
Amoled is only more efficient for blacks. Every other color it displays uses more power on AMOLED vs LCD. In fact, white uses 70% more power in AMOLED displays than LCD.
Watching 1hr video on Netflix over hspa+ at full brightness today dropped my battery from 80% to 29%. My galaxy nexus with the same use would have dropped maybe half of that.
Does that sound normal?
I'll be able to check if I have a defective unit pretty soon. I have a RMA for my earpiece speaker not working, but I'm literally stuck on a charger at all times, lol. I honestly don't really care about the crappy battery life, I still love this phone!
On the plus side, it seems to charge as fast as it loses charge, lol

I have owned mine since the 21st and I have noticed the battery to be on par with my S3 that is HIGHLY overclocked.... That being said, It could definitely be better! And the S3 has Verizon LTE so I don't know where all this drain is coming from... I use the same apps on all of my devices... Oh well! Time to get a good external battery...

Getting 3.5 hours screen on time here . with sync on , GPS on , screen 75% brightness. No issues here ,battery's great !!! " tweaking battery is waste of time . try letting it die charge it while off then another hour while on then pull charger , ( if anyone replies with letting die is bad your wrong , and u can send me all the links u want your still wrong
User error. You left a phone that has a massive 3100 mah battery for one with 2100.
My battery seems to be fine, previously I had a GSM GNex with the extended battery and my N4 has done just as well based off my usage.
I remove it from the charger around 7 a.m., use it all day for text, calls, browsing, emails. When I get home at 6 I am around 35-40% so I charge it for about 45 minutes to get me through the evening and then charge all night.
This routine has gotten me through virtually every phone I have had with a few exceptions (Treo 750 and SX-66 come to mind)
4.5 hours of screen on time is my average so far. Roughly 50% better then my Galaxy Nexus. Other than GPS remaining off, I haven't done anything special to conserve battery life. Not sure if I'm the exception, and I do wish I could swap the battery, but I can't complain too much.

Battery life dropping from 100% while playing game & attached to power outlet

With my Nexus 7 at 100% battery life & and being charged while playing my battery level drops. Is this normal?
Games include things like
Stand O Food 3 https://play.google.com/store/apps/details?id=com.g5e.standofood3&feature=search_result
& Supermarket Mania 2 https://play.google.com/store/apps/details?id=com.g5e.smm2
& this morning I played
Cogs https://play.google.com/store/apps/...wxLDEsImNvbS5sYXp5OHN0dWRpb3MuY29ncy5kZW1vIl0.
Same thing, battery started at 100% & I was connected to the power outlet. The Nexus 7 was showing as charging yet the battery level dropped as I played.
Are these really games that are that power hungry? Any more info needed please ask. Thanks in advance
Lots of love

your phones also isnt using a tegra3 quad core with a big screen
Yes it's normal. Depending on what you are running it might just hold even, drop, or charge very slowly. I have 4 android devices and they are all like that. Also keep in mind that the N7 has a big battery so even at a given charge rate it will take longer to charge which makes it seem like it's charging slower.

[Q]Uneven battery consumption

It is really strange that the battery comsuption of my new nexus 4 doesn't show uniformly.I mean it often stays the same figure for a long time,but drops very quickly in a few minutes for 2-3 percent,and then stays at the same number again.
When the battery percentage is above 50%,it's not very obvious.But below 50%,I can feel it very obviously.Today,I turn off my phone at 42%,but when i turn on the phone again,the percentage suddenly drops to 32%.
Besides,I want to say the the battery can stay for 15 hours or more.So the total time is obviously normal.I think it's not a problem of battery.But I am still a little puzzled.What can I do?
From the chart,I can see the trend of the curve change looks like steps......
It's not uneven battery consumption, it's that the reporting is kinda broken - e.g. it gives you the impression that it has used hardly anything for a while, then suddenly drops.

Well first of all rebooting the phone uses a considerable amount of power. You can't expect to shut it down and turn it on and see the same battery level.

You can't.

Sudden drops in battery percentage, why is that?

I've always been curious about this, when I'm using my nexus reading , watching videos or whatever I can see the percentage slowly decreasing according to use and it's all fine and normal. But then I turn off the WiFi and screen, and some time later I turn it on just for a quick check of mail or a doc and I can see a quick drop of 2 percent. It's not a huge deal but I've always been curious about this. I never have many apps running in the background, just the basic. Is that something to be expected with usage? I use better battery stats and there doesn't seem to be anything unusual that drains battery.
Sorry if there's any bad English there, I'm Mexican.

That's just the battery refreshing. Even sitting a minimal amount of battery will always drain, the status bar just doesn't refresh until a couple seconds after turning the screen on. Don't know why it operates like that, my phone doesn't.

Agreed - 2% drops are around normal... I often see such drops when I turn on my N7. I'm not sure how the the battery calibrates such things, but I wouldn't worry about it, cesarmanilla.
When you start seeing 'cliff-edged' 10% drops offs - Then worry!

I do think people sometimes obsess a little over battery issues - which gets in the way of them enjoying the device...

Mine does the same thing, drops 2% after its been on standby, also sometimes it drops 2% just a in general use too instead of the usual 1% anyone else notice this?
But your right I spend so much time fretting about battery life and not enjoying the device.

if my battery has any probs then it'll not charge upto peak i've chk the Vltg levels too...
I dont think so that battery has any probs coz before calibration on that particular ROM I was getting exact flow from 100% to 0%.....so after that calibration m getting that drops so Do I make a clean install or remove the battery profile.....how to remove that battery profile n make a new one?...
Ok, instead of reading around to fix your problem you made a new thread about the same thing.
There is a thread "battery drops explained", just a little down this very page that explains it all. If your battery is >1,5 old, it's getting worn.
Li-Io batterys have a lifetime (end of life is when it only has 80% of it's capacity left) of 500-700 charges. Nowadays people charge their phones at least every two days. Do the math. You'll see some more batterydrops at 20% and 70% (I think), the sum of these drops is how much juice your battery has lost permanently.
