One of the strangest charging profile I've seen.
That is weird. Miscalibrated battery, maybe? Try a full discharge, then recharge.

I'd never recommend a full discharge for an li-ion battery

It's not recommended to do often, but discharging has been known to solve issues with improper calibration.
Besides, you can't tell me you've never used your shiny Nexus 4 to 0% before ;P

Did you restart your phone while it was charging? I've seen strange dips and spikes in the battery graph on my Nexus S when rebooting while its charging. I haven't seen anything like your graph on my N4 yet but I don't check the graph much plus I've only had the phone about a week and a half.

very very wrong battery readings.....
happens lots of times after flashing.....weirdest thing that was happening to me was battery rapidly falling from 50 to 30% and than slowly growing to 40%.....

what kernel are you using? if it the devilkernel in the advanced options do wipe battery stats

Yes, I have to agree. This has also happened to me. I have actually had this happened when I turned my phone off one day. Before turning it off it had 60% battery, after a minute I turned it on and it said 20% battery. Also, has it happened to you that you charge it leave a couple of hours and when you unplug it rapidly falls to 70% or less? LOL! But it is nothing a full charge and batterystats.bin wipe wont fix.

Wiping battery starts has nothing to do with reported battery percentage. Similar results can be obtained by setting your phone face up on the coffee table, watching any random show on tv, and doing Zumba for 30 minutes. In other words... none.
Battery stats, which is only a list of the apps that have put a demand on the battery, is already cleared each and every time the os is rebooted

Yea, it happen to mine too after ICS 4.0.3 upgrade, does anyone can help?

This is what I have read on the XDA forums and it has worked for me.
Completely charge your phone to 100% (Full battery charge) without unplugging. Once it is charged, without unplugging it, reboot to recovery and wipe battery stats in the ADVANCED section. As soon as your wipe it, very quickly unplug the phone. (as fast as possible). Once you do this, reboot your phone and completely drain it to until it turns off and you cannot turn it back on unless is plugged. Once it is drained charge it completely full withot unpluggin it or turning it on.(Best time to do this is at night, since you are probably not going to use it while you sleep). After that just use it daily. You have to give it a couple of days so the battery syncs up. Hope I helped out!

No offense, but what you have read is incorrect and is rooted in a misunderstanding about how the os and li-ion batteries work.
1. Wiping battery stats does nothing pertaining to charge indication. The file cleared is an already blank file that lists nothing more than a list of the apps that have consumed power. This file is cleared by the is on every reboot already.
2. Completely draining the battery shortens its serviceable life.
Any "results" that are seen by doing the above are merely attributable to the placebo effect.

Use it...... Charge it often... try not to discharge the battery to zero. Calibration is not needed... This is a newer phone with new battery technology.

thanks I thought to calibrate it you had to discharge it fully then recharge
Sent from my Nexus 4 using xda app-developers app
Yeah just use it like normal. Don't worry about the battery bar too much.
Calibration is a myth
Sent from my Nexus 4 using xda premium
It is a good idea to charge for solid 8 hours and discharge to around 10% the first 2-3 cycles of the battery to condition it. But after that, use as you please, no memory effect or calibration or the like.
Only thing I would add, do not drain completely flat (0%) as it can negatively effect battery capacity, tho modern batteries usually have guards to prevent full discharge, for that reason
Calibration (full discharge) was for Ni-MH battery technology, and is actually a bad thing to do with Li-Ion/Li-Pol batteries

There is no memory effect any more. Just avoid killing the battery fully or leaving it charged for extended sessions, because the heat hurts the battery.

The thing about discharging to zero damaging the battery is another myth. The phone will report the battery at zero well before it reaches the "real zero". So there's an inbuilt safety margin that means you don't have to worry.

Hi ! So, i will receive my N4 in few days, and i would like to know what i should do to improve my battery life at first. Is there any way to charge and discharge the battery ? I read something like that on the forum but it seems very long.. Thanks for your answer

Calibrate the battery by running it down to 0% and charge it fully.
You can also root the phone and flash a custom kernel that offers great battery life.
Other things you can do...
Turn off sync, turn off GPS, turn off Google now, and lower brightness level to a minimum.

Yeah i was more talking about calibration. Is Just one discharge cycle enough ?

There's no such thing as battery calibration. Just use your phone normally, charging it when you want to.

Don't calibrate now.. your phone will already have the best calibrated battery settings.
Calibrate when you flash a custom Rom and that too,if you face battery problems. Otherwise no need. You'll do more damage otherwise. No need to calibrate if you flash a kernel over stock either.

You dont calibrate li ion battery.

And you should never purposely run it down to 0%.

It is a bit of a misnomer as the phone is calibrating the battery scale to match the discharge of the battery. It isn't that there is no such thing, it just isn't what people think.
Get the latest Franco kernel on it. That is all.

This. So much this.
What is the vest way to charge / calibrate the battery to get the most hours out of it?
Sent from my GT-I9505 using xda app-developers app
By and large, battery calibration is a myth when it comes to lithium polymer. Every now and again, an end user can run their battery through one full cycle to reset the battery's flags, but that won't have any effect on battery life.
Lithium based batteries do not benefit from any sort of priming prior to first use.

Hey, can someone explain me this?
I charged my phone to atleast 24% begore i went to bed cause last time i tested battery when i sleep, the battery dropped 20% in 10 hours, but now i charged it to 24% and when i woke up today it had slowly increased to 32%... what the heck? Can someone explain this to me?

wrong sub section but in answer, my s2 done that all the time almost after flashing a rom.
could start off at 100%, flash a rom and itd be at say 25% then start building up again toward its correct %. no biggy, its kinda normal :good:
Wrong section to post this but this problem also happens on my s2, it is something wrong with the fuel gauge. Just do regular charging and discharging and it should return to normal.

Your battery has a problem. Cause of overcharging.
Sent from my GT-I9505 using xda premium
If you've flashed a new rom, often the history of battery values and voltages get messed up. So its not really sure what percentage of battery is left when the battery is at X volts for example. Usually a complete discharge followed by a full charge should recalibrate the battery monitoring.

Try a few complete charge cycles. Hopefully it should fix itself coz its not really uncommon.
you should download battery calibration app
