Hi there, just wanted to check something out, I use automate it to switch my nexus off at night, but once booted again the battery history details start again meaning I'm not getting an accurate reading of how long the device has been going for on a charge. Is this normal or does someone know of a fix? I suppose i might just not switch off at night as battery drain is pretty minimal.

My wife and i both have MT4G phones. While mine works perfectly fine, My wife's is having issues that I can figure out.
First, let's say that she 76% left on her battery, the phone will just power off. But when the phone is restarted, the battery will be at something like 8-20%. Now I thought her battery was bad so I swapped her battery for my battery to see if i needed to buy a new battery.
With her battery in my phone there were no issues with my phone and conversely, her phone with my battery and it does the same thing.
Anyone else have this issue?
she probably has a rougue app. One that's juicing the living **** out of that battery. Look through her apps and see if any of them run while device screen is off. Its probably an app thats syncing constantly.
You can check these by going to settings/about phone/ battery/battery use. There's you'll see the apps that are running and which take alot of juice out of the battery.
You can also reduce sync for anything by going to settings/account and sync. Thee you can change sync intervals or stop anything from syncing at all.

This is common with mine, it does it while charging. Its not a rouge app. Cause ive tried it and cannot find any app that is running it unless its shadowed. I dunno but it happen a few times already. I use cm7. Now it can also be related to emmc chip. Kinda curious only a few people have these issuses. Wouldnt it be more wide spread and more people have problems with it, if its an app?

I would say to try and do a factory reset.

That would happen to me if I wiped battery stats in recovery.
And on some Rome.usually full wipe and reflash solved it.
Haven't wiped battery stats in a long time,and I haven't had that issue since.

I've noticed lately that my battery has been draining pretty quickly, but I've since chalked that up to an old battery that just needs replacement. But I noticed today that my battery ran out and my phone shutdown, but I went to charge it and immediately turned it back on and noticed that it read 50% charged. What is happening here?

As you already changed the Battery, I assume you'd have done calibration as well. If not, please consider doing it.
I have the same problem but I suspect that is because of battery, I'll be changing that soon and will write back
I'll leave this here in response to the advice to calibrate your battery

To get the best life out of a charge, flash a ROM on a full charge and then let the battery die and fully recharge it.

What kind of apps do you have?? Like apps that you think might drain some battery. Also use betterbatterystat app to monitor what's waking your device.

With stock, around 2 hours of screen on time is typical. You can prolong the battery life by disable Google Now, location service, email sync, Playstore auto update, etc. Check your battery stats (try better battery stats from the store) to see if any third-party apps drain your battery.
The better way to do it is to unlock bootloader, root your phone then flash a custom kernel. I recommend franco.Kernel. 3-4 hours of screen on time is typical with franco.

Might as well flash a custom ROM with it if you're going to use a custom kernel IMO. When a new OTA, OP will have problems updating to it because he is using stock + custom kernel + custom recovery.
Here is how to fix your battery problem.
1. Turn off location access in Google Maps settings.
2. Wait about a week for the battery to go through its charge cycle 6-10 times. Let it get as low as possible without the battery dying (this is really bad) and be sure to let the battery sit at 100% for atleast a half hour or so when fully charged.
Each day you will see your battery life increase and when done, you should be getting around 5 hours screen on time.
Well dramatic change in battery life as displayed below. Now after having a read in several topics it seems like a fix is to have the wifi on. How strange as this goes against the ethos of all previous smartphones i have owned i.e. wifi on drains battery. I have uninstalled a few apps and also switched of location access, so to be sure that the fix is wifi related i will switch wifi off the next time i do a full charge and see how that behaves. By the way android os is way down in battery consumption now.

I just got my nexus 4.
Last night I charged the phone completely, disconnected if from charger and turned the phone off.
This morning when I turned it on the battery was drained 15% down to 75%
Does anyone else have this problem?
Defect with phone?
Thanks for help.
You have to let the battery settle and let the battery stats calibrate. The % that you had after rebooting is what you really have. The first time it wadjt showing the right amount.

He said he turned his phone off...
I don't see how it can lose 15% if it is completely shut off. That's weird.

Then when he turned it on, he "lost" 15%. Like I said in my post, what it said before he turned it off was wrong. He didn't really lose 15%. It was just displaying the wrong thing.

You might have some apps running in the background that is preventing your device from going to deep sleep to conserve power. Check what's running in the background when your phone is off. You can use better battery stats app to check what's consuming your battery level.
Are your running a custom kernel? I've heard of a few cases with kernels where even though the phone is sleep and screen off just touching the screen will cause battery drain.

I'm guessing you either meant it was at 85% or drained 25% down to 75
Either way this is common on a lot of phones now due to the way the battery gauge works. When you turn your phone off then on it doesn't always remember where it was so gives a value and then if it's under where it should be it soon recalculates and can either starts going up or stays on the same value for a long time. This has happened on both my old SGS2 and also my N4 for example this morning while my phone was being drained by the FB app keeping GPS on, I turned off location access and then restarted my phone which dropped a few extra % and then sat for a good few hours at that % even though I used my phone.
Moral to the story is don't always take what you see as true, give it time to settle and see how it goes over a few charging cycles.
My nexus 7 was fully charged and I put it in the rack in the night. Next morning it shut down completely. When I switched it on, it showed battery 0% says 0% the same c thing happened today as well. Its a new device. Any idea??

Some app or service is draining your battery. Get BetterBatteryStats to narrow it down.

Like someone said before it's a rogue app and the only way your going to get the battery drain issue to go away is to figure out which app is doing it and then get rid of it.

I think the best solution for you is to factory reset or re-install android on your device once.
It will be easier than finding out where is the problem. as screen snap shows most of the battery is drained by "android OS".
It was just my opinion you can take it if you want.
My battery usage. Even though my screen on time was only about 2 hrs most of the battery was drained by the screen. So there music be something very wrong in your case.
I don't know about android virus but that might be an option.

Gonna follow along and disable my daydream as well since I'm having the same problem you are with it actually draining while on the charger (Stock ROM, Franco Kernel, OEM wall wart with gold tipped USB cable). Tis quite annoying to have to either keep the screen off or power down completely in order for this bad boy to charge...
