Nexus 4 Battery - Nexus 4 Q&A, Help & Troubleshooting

So I have nexus 4 with battery that was bad it basically would die at 18% just shut off. So I replaced with new battery and I charged it right away to 100% and did battery calibration as soon as I unplugged it it said 79% every time then I plug it back it and it instantly counts and climbs back to 100% within min and once it hits 100% it fine it will drop normal I'm not sure if I shouldn't have done a battery calibration to brand new it like it remembering old battery now it does this every charge cycle it annoying.

There's absolutely no need to calibrate the N4's battery. You just don't need to.

What do I do now cause every time it shows 100% then drops to 79

Better put back the original battery and try this:
1. Leave your phone to turn off cause of battery drain
2. Immediately reboot at fastboot mode and leave it alone for some time, till it gets off again. This is the real point 0 of battery.
Now charge it till 100% without using it.
After that use it normally and inform is if IT got any better.

So I bought new battery this new battery won't hold a charge past 79% so I ordered a new one I f!ash Stock and Relocked Boot loader now when I get new battery in it prob gonna be dead should I charge it til 100% and another 4-6 hours after to get beat life right ... Then run it once or twice till it complete dead and charge to 100%

Atrix not charging past 88%

As of Saturday evening, my phone will no longer charge past 88%. Earlier on Saturday, the phone was charged to 100% in my car. We lost power and the phone ran down to 3% before I was able to charge it again.
After charging over 8 hours, the phone would not go past 88%. Any ideas?

I have not tried that. Weird thing is, the battery calibration app reads 4196mV at 70% while charging and ~4200 while at 88%.
Just go to CWM recovery and wipe battery stats. Do a few charge recharge cycle. It should be OK.

Charge to 88% or until you notice it not going any further. Turn off the phone. Plug in the charger and wait until the battery display shows. While the phone is still plugged in, remove the battery. Wait for it to boot up and show a no battery icon (or something like that). Once it does, put the battery back in and leave it for about 30 mins. When you hit the volume buttons, the display will show between 5-10% charged. Anyway, after about 30 mins, turn the phone one and it should show 100%. Re-calibrate the battery after that using the app or recovery.
Are all android batteries like this? I've never had a device with such finicky battery stats. I too have the 88% problem and i feel like im recalibrating every week. I will try again.

I don't think they're all like this..but I know its as annoying as F***. Every morning almost i'm doing the "battery pop out" trick just so that it'll read full. It would be different if it read 95% or something and stuck there for awhile until the battery caught up to the actual reading..but it doesn't. The battery continues to drain at a normal rate, so you basically lose however many % you had initially.
Definately annoying..

so you're having to do the pop-out trick every day? that's definitely not something you should have to do....... what gives with our battery?
Mine did this before and what I did was run it all the way to 0% and it cuts of and will not start, then charge it to 100% with the power off and and then boot it up. Work like a charm for me.

do you have the same battery issues on your galaxy?
So I've been sitting at 1% for the past hour. Been playing games, have wifi, bluetooth, GPS all turned on.
Thing will just not turn off!
EDIT: Right as soon as I post this, it turns off. Over 1 hour on 1%.
Will recharge tonight and hopefully it works right.
I had this problem for a while but you should know that it will fix itself eventually. The phone is fully capable of re-learning the limits of the battery and after several days will begin to display the correct charging status. Mine took about a week to start displaying 99% in the morning.
This happened after I did the complete discharge, charge, pull battery, charge again, then boot procedure. It was fine for a couple of days then started displaying 82% as a full charge then slowly got better. I'm fairly confident that I'm not leaving anything on the table in terms of capacity either since with moderate use and turning off wifi when I leave the house I'm getting about two days of charge.
Sounds like a jumping battery problem to me.

[HELP] Big battery drain. 1 hour battery life

Ok I lied, it's not one hour backup, it's 50 min battery backup. I charged my phone to 100% 4163mv and played about 2 songs, battery dropped to 47 and then suddenly 0%. It all happened in less than 50 min. Just when I was thinking, it can't be more worse. I charged and battery was 99% :O. Another time, phone shut down at 40%, when charged moved up to 70% and number started increasing every 3 seconds. I did calibrated it many times so that's out of question. I bought this phone in May so I will be surprised if battery is defective. I'm confused. Please help!!

Download from market app called Battery Calibration.
Open it and connect your phone to the charger. When you have 100% status, and ~4200mV click Calibrate and unplug your charger.
Then set the LCD Brightness to max, set timeout to never sleep or just use your phone to fast discharge it(that doesn't need to be fast and doesn't need to be slow it just need drop to 0%).
Let it automatically die because of low power, and then charge it to 100%(you can use battery calibration app to see the voltage, around 4.2V it's max).
After that your phone should have a much better battery life.

Battery level display bug?

A quick update on a weird bug I encountered in the N4 yesterday. I was outside and got home with my battery at around 50%. I plugged the phone in and look away for a couple of minutes and when I looked back at the phone and the battery was at 100%(!).
I knew this couldn't be right so I checked the battery graph and it showed a steep jump from 50 to 100 in a matter of minutes. I did a phone restart and the battery was back to the correct level and went back to charging normally. Unfortunately I forgot to screenshot the battery graph and after the reset the graph was reset as well.
Could this bug be one of the reasons why certain users are reporting very bad battery lives on the N4? I can imagine that if I had not been paying attention with the charging and just took the phone out to use later, the battery would have seemed to drop very quickly. How commonly could it happen even; has anyone else seen it?
This happened to me last night. I plugged it in to charge and it said the battery was at 100

This happened to me only once. I jumped from 1% to 100% in a minute I was like no way this thing charges that fast lol

Does seem like it is a common problem then. Better keep an eye out on the battery when charging it.

Add me to the list, a reboot after I observed the nano second charge to full capacity didn't even make it display properly. I didn't try a hard reboot however.

[GUIDE] Preserving Battery Life

This is particularly true for those who are un-rooted and on Stock where wiping battery stats is not available.
I bought my N4 on 1st of Feb, and the first two charge cycles, when the phone powered off due to the OS reporting the battery at 0%, I was unable to power it back on. This is great, as the phone battery is truly empty!
Some charge cycles later, my phone would power off due to the OS reporting 0% - however, I would feel as though the battery didn't last as long as I was used to.
So to make sure the battery is truly dead... I boot into fastboot mode by pressing Volume Down and Power on straight after it shut itself down. The phone stayed on for a further 27mins, bearing in mind that in this mode, the screen is on full brightness and always on. 27mins of screen on time for a phone that manages only about 4hrs of screen on time at best, is a considerable amount of left over juice in the battery that the OS is missing out on.
Normally to correct this, we charge up to 100% and wipe battery stats in CWM.
[GUIDE]
I have found that to leave the phone on in fastboot mode until it drains the battery out completely, plug in your charger, then boot into Android, would show the battery at 0% - this is a TRUE 0%... charge it all the way up to 100% and you should have back your full battery performance. Don't forget to allow the 99% - 100% time. This is very important - It will make it to 100% eventually, be patient.
This is all based on my assumptions/guestimates/theory - please do comment and correct if you are the wiser. [though for now, it works flawlessly]
OT - This does highlight a flaw in the OS however, it's a problem with all Android devices, will they ever fix it?
You're just calibrating the battery. I'm sure most of us already let it die without needing t enter fast boot.

Also, you should not drain it to such an extent. If a battery ever reaches true zero, it won't turn on again or charge. The phone turns off (says zero) around an actual 5% because they don't want you to destroy your battery

I guess I wasnt clear or there was a misunderstanding... I let it die, reaches 0% and starts to power off, I then boot it into fast boot mode, and find the battery with at least another 30mins of screen on time. This extra battery is what I'm trying to calibrate back into the OS stats.

Good observation, always worthwhile hearing other opinions. I would say though, that 30mins of screen on time would be more than 5%.
I'm in my experience, the phone was fully dead after leaving it on in fastboot mode, battery all out. Then I plugged it into the charger, I got a flashing red light, and then the battery charge icon appeared. I then booted up and the OS reported a true 0%. This charge cycle, since I did this I'm at 28hrs with 20% to go with everything on [Wifi etc]
But so far, it's been a great way to get the most out of the battery.... lets get some more opinions, good or bad..
All thoughts welcome!
The flaw in this argument is that wiping battery stats in recovery does absolutely nothing.

If that really is the case, then surely that makes this approach even more convincing as something that "works" in maintaining good battery life!

You can't drain the battery fully when its on because the device has protection against draining the battery to a point which will damage it. In fast boot this control is not in place.
Is this worth doing? No. Our battery aren't replaceable and shortening its life to gain 5% is not worth it.

I understand, good point, however we're not talking about just 5% here!
Explain how I was able to get an additional 30 mins screen on time!
Sent from my Nexus 4 using xda app-developers app
As skeptical as we can be, a lot of things can affect battery life so the extra 30mins could come from a number of factors.
On another note, I usually get 4-5 hours of screen time on my nexus 4.

Because it takes much less battery on fastboot mode? Radios don't need to be on , brightness is minimal, only 1 CPU runs at lowest frequency, flash memory is not powered on?
To have a logical argument here, we must know how long fully charged battery lasts under fastboot.
And in agreement with many other voices, I don't think draining battery obove manufacturer threshold is a brilliant idea.

[Q] Strange battery problem?

I've had my nexus 4 for about 6 months and started having battery problems about 2 months back. My phone would just get worse and worse as time went on. It would randomly die when the battery was at 40% and would only get 2 hours of sot. Later it got worse and died at 70% getting only about 1 hour of sot. Now it got to the point where its unusable without a charger, if I unplug it the phone will last for 30 minutes max and then shut down. When I try to reboot it after it dies like this it boots up and instantly dies after about 5 seconds. Sometimes the phone reboots while it is plugged into the charger, while unplugged the phone instantly dies if I take a photo especially with flash. I tried resetting the battery by unplugging it and plugging it back. I noticed that the battery has expanded in size, even making my back cover not flat anymore. My question is if I replace the battery will this solve my problems? Here is a few screenshots of my battery stats:

Replace the battery ASAP or RMA the device for a new one. Those are all telltale signs of a bad battery, especially the swelling. Strange that it happened so early though.

Hello mates,
About the Battery.
2 days ago I flashed the 4.3 factory image, I slept yesterday night and the phone was on 43% of battery at 1:00 am. When I woke up 9:15 am today's morning, I found that the battery in JUST 4% !!!!
could you guess the problem here ?
I never used Hangouts, nor Google now.
By the way , I'm using STOCK ROM with FRANCO KERNEL.
If I'm not mistaken, before the phone powered off, the screen on time was 47% ( 2 hours ), Phone Idle 6%, and Cell standby was in 9%.

Strange but, your problem is probably only due to the software, maybe you didn't wipe cache or dalvik or just had a bad install, although if its persistent like mine replace the battery
