[Q] Nexus 4 Instant Battery Drain/Shut-Off

Hi
I have recently started having a problem with what I presume to be the battery of my Nexus 4. It seems to have started suddenly about a week ago, though was working absolutely fine before. I don't think it was due to any specific app having been installed. I have also done a factory reset on it, but that didn't solve the problem.
Basically, the battery will discharge to about 75%. The phone will then suddenly switch off; turning the phone back on, it simply shows the battery to be fully depleted and switches off. If I plug it into a power source, the phone turns back on and begins charging, from 0%, though seems to suddenly fully charge it within about half an hour.
My phone has not been rooted.
I would really appreciate any help/advice on this issue as it is incredibly frustrating having to have my phone almost permanently on charge.
I have attached two screenshots of the battery usage graph.
Thanks!

If you are on stock, try flashing the stock image(4.2 or 4.3 up to you) there's plenty of threads on here thatll guide you thro the process.

I've had the same issue about three times, during the first week of using my Nexus 4 (about half a year ago). I've already had my mind made up to RMA it, but waited for it's shut-off to happen once more to collect some evidence of this problem and... it never happened again. I'm pretty confident that I didn't install anything that might have helped (I only installed BetterBatteryStats to check the instant drain, but really doubt it could change anything, it's just statistics), and I've never factory wiped the phone's data yet.
I've been searching for answers around the internet back in May, but never found anything of value, so my only advice is... wait a little, and if it doesn't get better itself return it to the merchant. My previous HTC phone was restarting almost everyday from the first day I bought it, until a month later I returned it for warranty repairs and after they changed almost all internals of the phone it never crashed again (till today, since I still use it as GPS and media player when running).

SM-N910C heating problem after 5.1.1 update

I want to share my experience which is causing me trouble now.
I have a Note 4 SM-N910C which had an issue after updating to 5.1.1 lollipop. For about 2 days after updating, a strange thing happened to my phone. The whole phone gets hot. The screen, the sides, the back, you can feel that it is hot. At first, i thought of turning it off to cool down the device. To my surprise, the device is still hot even if it was turned off. So I removed the battery. Turned it back after 30 mins or so and restarted the device. But this time it won't turn on. I charged it and the battery was still at 25%. Then it turned on, the device slowly heats up. I then fully charged it and see if what is going wrong. But i cant think of anything i did for this to happen except disabling some apps in the application manager since there is still no root for 5.1.1 that time. Still the problem persisted for a day and my device dont last for more than 3 hours from full charge until it drains.
Then i decided to downgrade to 5.0.1 lollipop. But still the problem remained. I decided to show it to a technician, told about the problem and he said, there a lot of note 4's brought to them with the same problem. He said it is a common problem of note 4. What causes the issue he said was that the Power IC id damaged. And it is hard to repair. The solution is either to change the board of the device or change to a new one if under warranty. Since I tripped my knox, there will be no other way except to change the board which cost 75% of the price of the device or I will dispose the device.
If there are other solutions, i would be thankful for it will help me keep my device. I dont have the money to secure a new one.
What could have caused this problem? Thanks for any solution i could try..

Note 4 (N910F) restarts itself

I finally upgraded from S5 to Note 4, I've had my phone now for 2 weeks but I have a problem!
If the phone is asleep (I mean screen off and I haven't touched it) after around 2 hours, it's like it's powering itself off! Because when I put the screen on, the samsung boot logo comes on, not the first galaxy note 4 screen but the second one. After that I can unlock the screen, so it doesn't really reboot completely because otherwise I would have been forced to unlock my Sim-card.
I'm rooted and I've tried different roms, norma v26, batman, black dog, apocalypse.. but now I'm very satisfied with AstraDream UX. Also I've tried flashpoint kernel but I'm satisfied with Ramkernel. But it doesn't matter what I run, the problem always occur. For example, this morning I missed my alarm clock.
I attached a screenshot where you can see that the phone went off around 3 am, I locked it a half hour earlier. Then I woke up 07.50 am and as you can see, the battery drained a lot. I had like 95% then in the morning it was 60 something.
On betterbatterysaver I can't see anything because it restarts its counting from boot, but on GSam, it says that since full charge, the device been on 4-5 o clock am. But it was full charged at midnight.
Someone who know about this problem? Or someone who know a good log program so I can see what's going on?

Looks like you've got the dreaded emmc problem! Search and you will find!

I don't think so, because everybody who have that problem describe that their phone reboots completely several times or they can't boot or they get error message. Also I checked emmc check and it passes. My phone only reboots if the screen has been locked for more than 2hours, and it doesn't completely reboot, just a fast reboot.
It's like it's not completely off because I can press home button, then the phone starts from Samsung logo and then I'm in, no sim card pin either.

if you leave it plugged in does it reboot after few hours of inactivity? If not then maybe try another battery.

No, plugged in it doesn't reboot. I was thinking it was a battery thing, because one day it suddenly fast drained from 25% to 15% and then suddenly it died.
So I got a second battery when I bought the phone and I tried that one, and I got a better battery life and I thought no reboot problems.
But then, during a call after around 1hour, it did the same thing and rebooted to the samsung logo. Also during another call, when I unlocked the phone and opened Textra it rebooted.
Another day I saw it reboot during inactivity for around 15min after a full charge and now yesterday it rebooted when I was going to enter Google Home.
So now I'm back at stock and running stock kernel, so far so good.

You should try wake lock application and use partial wakeup to keep your device from freezing

Faulty

First of all -please excuse the thread's title, but I encountered an issue where I couldn't input content in the "title" box unless I refreshed the page and started typing before it loaded the page fully (tried on both Chrome and Firefox - VERY odd).
Recently I've encountered issues with the phone (N910F) getting really hot and shutting down the phone. I was in The Philippines at the time and the daily temp was around 34 degrees so I thought this may have had something to do with it. One battery in particular, whenever I used the camera it would shut the phone down. I stopped using that battery and then eventually the other 2 have been doing the same - they are all after market batteries bought from Amazon from Anker and Rav power and within a year old. But then it would get worse and the phone would just randomly shut down - it seemed to make no difference if it was at 90% or 30, it would just die. I'd often have to do a battery pull and hold down the power button just to get it to fire back up again. Over the last 2 weeks it's gone form a few times a day, to multiple times an hour! I even tried to limit the load by changing the governor to "powersave" and that initially seemed to help matters.
I figured it could be one of three things going wrong - a software related issue, a hardware issue with the phone or failing batteries. I installed [ROM][N910G/F][ODEX]* DQL1 * Multi-CSC, De-Bloat stock, Fast&Light[CUSTOM] and it was a while till anything happened but then once again - it shut down. So I don't see it being ROM related, I'd only added a couple of basic apps too, so I cant see it being a rogue app.
My last N910F had the EMMC failure and I recall that it would regularly freeze or lag heavily then crash and bootloop, but normally my phone just shuts down. I'm hoping that this means it's most likely battery issues, but it seems strange that all 4 batteries would fail within a 5 month period, especially as they were all on rotation. I even took to only charging them (in a Samsung external charging cradle) on an evening when the temperature was cooler. I've contacted both manufacturers but I know that Anker dont have any replacement batteries anymore, so I'm hoping Rav power will replace that faulty battery (that one started to swell a few days ago.
So, what do you fine fellows think is the likely issue that I'm encountering? I don't want to throw good money after bad and buy more batteries if it's likely that it's a phone issue, but I also don't want to get rid of the phone if I can get it working again.....
(I'd been running the Resurrection Remix Rom on Nougat for about 10 months. I went traveling 8 months ago so I didn't update the ROM as I it wasn't super stable at that point and I was happy how it was working - if it's not broke, dont fix it! But after a while I started to have issues and one of the batteries began to swell. I got rid of that one and switched between the other 3)

Another strange battery thread

Hey,
yes i know: another battery thread. But tbh i havn't seen a thread with a similar problem description so far. Im using a Note 3 SM-9005
After my Note3 got super slow with normal samsung rom, i decided to flash it and install LineageOS 14.X. It works amazing! Feelt like a super new phone to me. Just some problems with rotation but i could life with that. One year later my battery started to drain faster. But a while after that i could fully charge my phone, watch some YT videos (like 20min overall) and then the phone just goes off. Its super hot near camera (processor i guess?) after turning it on again it was at 1%. 1 Month ago i tried to finaly fix it by flashing to LineageOS 15.X (Android 8.1) but the problem is still the same. And now its not just videos, if the phone screen is on for more then 20min it will turn off (even if it says 50%)
But not enough.
- After shutting down automaticly, it start itself again and shutdown again and so on. Until i plugin a charger then it stops doing it (or if i remove the battery).
- If im just listining to music it works fine (no screen on time), but while listining music in freezes for 1 up to 3 seccends (on avg every 10s one "freeze")
- It can happen after 5min of usage after charging it to 100% or i can listin to music for over 70min, than can have it in my pocket for 9 hrs, can hear music again for 70min and it still works (all of that with less to none SOT)
I havnt tried so much tbh, cuz i always thought it is a battery problem. But the new battery I got 2 days ago still has the exact same problem. I've read something about save mode and I booted it in save mode and the phone didnt get hot (not even warm!) with 20min SOT browsing (had no time to test it more). But the only apps that I have installed are Spotify, Firefox, WhatsApp and the Blizzard Auth.
Now i tested using a calibrate battery app (my phone isnt rooted but the app said it worked) and now im charging it up to 100% again to test it. But I dont think it worked.
Anyone here with more ideas I could try?

One full wipe and install stock rom .
Charge battery and test over two weeks .
Calibration app NO thats fake it does not and cannot calibrate a battery ( see multiple posts )
Its just the usual battery question and a search answers your question .

How long have you been using that battery? Get a new battery and your problem is solved.
I had similar problems with battery charging to 100% and suddenly going down to 50% and suddenly switching off. Changed battery and all was well again.

I just bought a new battery. TBH it defenetly cant be a good one for that cheap price. But I just flashed back to Stock Rom. With the old battery same problem, but with the new one it works good so far. nearly all bugs that came up the last few month are gone. While setting it up, the phone got really hot (it had to work pritty hard i guess to update everything). This is why JJEgan mentioned to use it for atleast a week i guess.
But an important question: is it possible to flash back to a new version again after like a week? Or am i now forced to use this stone age version of Android. (I guess all samsung apps can be removed if i decied to root the phone)
