[Q]Uneven battery consumption - Nexus 4 Q&A, Help & Troubleshooting

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.

Nexus S battery

Hi did anyone experiance this kind of battery consumption? 3days 14hours and 45min and still have like 7%?
Not personally, I use my phone too much to get that kind of life out of it. Based on what I know about the drain when it's screen off and sleeping, though, I think it's well within the realm of possibility with light use.
I get like 24 hours out of mine... with some light-moderate use... used to be better when I bought it but then after installing some apps it just starts degrading a bit I guess
Well, rechargable batteries do degrade over time, and the more apps you have on a device, generally the less time it will last on battery, partially because those that run in the background consume more system resources and partially because those that update data in the background will keep your phone "awake" more of the time.
If I wasn't using my phone and just let it idle (sync on, airplane mode off) I'd get like 12 days of battery life. That's what I like about the NxS, unlike other smartphones it does actually last longer when not used.
hi
i am getting around 10 to 12 hours. wifi always on. mostly watching youtube videos. netbrwosing. gaming.
2g phone calling
still i think i am getting reasonably good back up
Disabling wifi,gps,bluetooth and reducing screen brightness will improve battery life.

So will removing the battery and placing it next to the phone.
My wife and I both have the Nexus both with battery issues never charging to full 100% always get 95% max. New phones. Battery usually lasted 10 to 12hrs

That's no issue, but working as intended.
Other phones are using the same technique, but they are hiding it by showing the 100% the phone never reached, that's why they drop to 95-97%ish right after unplugging and from there drain normally.
I experienced battery drowning after using app's like maps or latitude. I had to kill them manually, now I'm cleaning the phones memory regularly. That safes a lot of battery life for me on the one hand, but on the other hand loading app's isn't as fast as before.
It's the classical trade-off between battery life an usability. And 10-12 hours are normal for me if I'm using my phone a lot.

Just read about it searching. It's a safety setting. Surprised none of the galaxy s phones had this on. I had epic4g before.

Well, depends on the manuf. if they want to "hide" it or not, they could also set 95% capacity as "100%" displayed. All batteries got a safety feature of some kind
20 hours of hardcore use here
Can't be too hardcore, display lasts 4.5h max

same here.
never rooted or installed a custom rom.
in 2g idle it lasts ~14days
9 to 13 hours ,was looking at getting maybe better battery but dont think theres one
So 95% is the new 100% because my phone won't charge to 100%. It just stops at 95%.

I did not know that was built into the battery thought it was the phone that controlled that. Thanks for info. I'll see what these ebay batteries I purchased for $10 from china do. Should be getting them soon.

Battery Won't Idle

It seems like my battery won't idle after it drops under 100%. I can leave it off the charger at 100% and it won't drop. But after that it'll drop 2-3% every 2-3 hours I don't touch it. What gives? Looking at the graph there is no wake locks period. It just slants it never flat lines it seems like. WiFi is not on and it deep sleeps. But the battery drops over nothing.
Left it over night at 71% and it dropped to 68%.

Mine does this too, I have noticed it since the start with every kernel/ROM
I can leave it for ages or even use it for a while, and it stays at 100% but below 100% it doesn't do this
However I have noticed that this occurs more on some kernels than others. eg. Bricked which I am using now, does not last as long on 100% and goes down normally from there.
I have read people thinking their battery life is amazing at 100% but honestly I think its a bug or something in the reading
Please correct me if I'm wrong

Its a possibility I never had this expierence before 4.1.2 got put out. I honestly think that it was a bug introduced. Or something not entirely sure. Thanks for participating.

Issue is I've never had this till just recently. It'll idle perfectly after a full charge at 100% but start messing with it and it'll drop 2% every time I let it idle every 3-4 hours. Hell not even that long some times. Using betterbatterystats to see if its an app. As I see that the CPU time using States doesn't match the display time. So its awake when the screen is off and isn't showing up in the battery graph.

Is it not normal for a battery to die even if a device is not being used? I don't see how it would remain the same % if its not plugged in.

Please help?

So I just bought the Nexus 10 a day ago and I'm worried about a few things. The device gets hot/warm under minimal usage like browsing Chrome near the rear camera. It also seems that the battery life is terrible, like four hours to go from 80% to 0% with light usage. Also I've noticed that the screen randomly flashed brightly once or twice when it was turned down pretty low. Does anyone think this is cause for worrying or is it normal? Thank you for any answers.

Sure doesn't sound normal to me.
Mine never gets warm with light usage. Sounds like you should call Google and RMA it. Look up Google play contact, and call their number

Not even around the camera? Any word on your battery life?
Sounds to me like your frequency is stuck at max, or you set it there without realizing it.

I don't think so.. but I have a case on it now and the camera is the only exposed area. I don't think it gets warm from normal usage, but probably if I play a video or game. Then again, climate varies (also temp of hands affects heat perception). But next time I use it for an hour or more I'll take the case off and feel it.
Unfortunately I haven't done much testing on battery. I did run it down once to 20 percent once, I forget how long it took. But I'm sure it's longer than 4 hours.
What is your display?
And what does it say under battery? Usually screen should be main eater of battery unless intense apps are being used.

Ok, well mine seems to be doing better now with a few charges. Here's my battery info, I've only had it on a little today.
I had the same thing happen to me. After a few charges the battery lasts longer... Up to 2 days with consistent daily use, for example.

Ok, I was just worried something was wrong.

Why is my battery time rubbish?

Looking at others screenshots, I am only having half what the crowd having.
This is not the case for the n4 only. I am talking about every single Android I had in the past.
Is something wrong with me or what I see in the screenshots is 10% brightness, all the services off and staring at a black screen for 8 hours?
People's usage varies. Some people listen to a lot of music. Some use navigation frequently. Some have Google Now running, while others don't.
That said, I use automatic brightness, get on XDA a LOT, make a few calls and texts, and talk to people on gtalk. I usually see around 4h screen on time. Could I get more? Yes. But I don't care enough.

Good signal reception in your area is key to battery life.

Because u own a nexus device with no replaceable battery and and and underpower battery. Google posing that they are giving u cheap phone. They took from u all the real things that we need and gave us what makes little difference.
Less storage so u will be using their cloud.
Not replaceable battery so after a year or less you instead of replacing battery by sending phone to service centre, buy their motorola X.

That, I can understand.
6 hours guys, I honestly have no idea how they manage that. When I turn on the screen, consumption jumps up to 600mah straight away. 2100/600= 3 hours + some minutes.
Btw I can literally see the cell tower from where I live. Reception is no issue at all.

List all the apps you have installed. Is Facebook one of them? Remove it.
Install betterbatterystats, check if some app(s) keeps your phone awake.
Way better if I don't use it much lol..

If you're using the stock Email client(not Gmail), that might have something to do with it.
I found out, by using Elixir 2, that the Email client was pretty much constantly using around 20-30% CPU, even though it wasn't showing up in the battery stats. Once I stopped using the Email client(removed all accounts) my battery life improved a lot.

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.
