Nexus 4 sudden battery drops, sim pin requests

Hello all!
So I've owned the N4 since May 2013, it worked great, but right now some severe issues popped up. These issues include:
1) Sudden battery drops for no reason at all. The battery stats look horrible and nothing is draining the phone. See for yourself - added screenshot in the bottom of the post.
The battery drops often lead to a weird flat charge level. For instance, the battery immediately dropped for 20-30% (let's say, leading to a 50% charge), but that that 50% charge can remain for quite a while. Once it was like that even on 1%. Restarting the phone sometimes may bring the battery % up, but still the draining is unbelievable.
2) When the battery is below ~15% all hell breaks loose. I'm loosing the cell signal, sim pin requests pop. Basically, it's either charge the phone at this point or the phone will die in a couple of minutes. If you're using the phone with such low charge, the (what i assume) radio module restart will kill it soon.
Phone never been repaired, the screen is original. Also, the proximity sensor died (i guess) and I've had to flash xposed and install the "turn off prox sensor" module.
What I've already done:
1) Format cache
2) Factory reset
3) Clean flash stock ROM
4) Clean flash other ROMs (currently on Android M Chroma)
5) Flash older stock radio modules (thought it may prevent radio restarts)
6) Limiting my radio to only WCDMA mode (3G or nothing, instead of 2G/3G mode)
7) Replaced the battery few days ago (didn't help at all)
One more thing: my wife has the exact same phone, bought approx. same time ago. Bought from totally different places (one from Poland, second from Italy). Her phone has very similar symptoms, although, not to that extent. It means that her phone battery is also suddenly dropping and sometimes sim pin requests appear, but it's less frequent and not so bad as with my phone.
If you have any ideas how to pinpoint what's wrong or maybe even a solution - that'd be great. Thanks in a advance.

Probably time for a new battery as the phone has been used for almost 3 years.

It's a number seven in "what I've done" list it was my last resort to change the battery and that didn't help at all (immediately saw the same symptoms). That's why I'm clueless and wondering if the phone is basically dying...
Thanks for the reply though.

Are you sure the replacement battery is good?

Yeah, it's new and bought from the reliable store.

Try the new battery in your wife's phone?

That would require buying one more battery, because the original is so strongly glued to the case, that I will destroy it in the process of taking out (like I did with my own). So not really the best option to continue buying new batteries for allegedly fried phone

I understand. Maybe you need to apply more heat to loosen the adhesive?

Any Luck ?

I am facing a similar issue, did you find any solution ?

Unfortunately not.
Battery replacement did not help. Also tried replacing charger port controller on the motherboard, but that did nothing as well.
Ended up buying new phone and selling this one for dirt cheap amount of money.

The same started happening to me a couple weeks ago.
I think it's time to change to nexus 5 (or similar)

Same is happening to me, the cheapest solution is to use a power bank as I'm not ready to leave my Nexus 4.

N910c battery issues?

Hi people.
DISCLAIMER:
-N910C
-Without any kind of modification (no root, custom kernal, boot recovery etc)
-Android 5.1.1 (XME) (N910CXXU1COJ5) (latest update provided by samsung as of 3rd May 2016)
-Original Samsung charger and usb cable, both charger and usb cable in good condition (just so you know asking me to change my charger, I tested it by charging my other samsung devices -- no problem)
Let me jump straight into my problem and hoping that someone would be able to help me.
The phone stop charging at 88% / 89% / 91% / 92%
How I know they stopped charging at the percentages mentioned? Plugged it in before sleep, 5-6 hours later it stuck at one of the percentages mentioned, most commonly 91%. Check the battery usage graph and it shows a straight horizontal line at 91% and onwards, and indicates like 13minute until full charge which it never happen. The device and the charger is not warm/hot, you know when they are charging they tend to get a little bit warmer.
Not always, meaning not everytime I charge my phone then it stopped charging at the percentage mentioned above. However, I would say it is about 8 out of 10 times. I read a lot of articles else where saying the same issue but different device. They came to a conclusion saying that is a hardware defect. Which, I do not think so (At least I hope it isn't). None of them mentioned if they charge their device with it power off or not.
So I tested it out a few times, both with the device on as well as with the device off. I noticed that with the device off, it can charge from 0% to 100% no problem (fast charge or not, same). So I would like to draw a hypothesis myself, it would be a software issue, I've no idea what but apparently some software bug/issue stopped it from charging further.
Not forget to mention that the battery constantly dropped straight to 0% when it reaches 5% (faster than vin diesel man), and sometimes it drops to 0 from around 5 - 20%.
Reformat, clear data, wipe cache, done it thrice = same issues remained. I also use some of the methods claim to be able to 'calibrate' the battery without root, also no cure to the current problems.
All these problems came along after the 5.1.1 update is what I am believing now. So I tried to downgrade it back to 5.0.1/4.4.4.
Guess what, I found out that Samsung locked the bootloader starting from 5.1.1, which prevent me from downgrading.
So my questions are:
1. Do anyone has any idea how to unlock the bootloader in android 5.1.1 without triggering any sort of knox counter?
2. Have anyone experienced/experiencing the problem, any solutions?
3. Have anyone tried 6.0.1 marshmallow? Do you have any problem as mentioned above? This will serve as an alternative if there is no way to unlock the bootloader in 5.1.1.
4. Can you downgrade from 6.0.1 to 5.1.1?
Thanks for your time.

No, that app is ... let's just say it is not helping. Ahh... but my battery is only a year old, and I've been taking good care of it as much as I could. Still thinking to invest a new battery or nah..

Thank you for your information! Anyway, I still would like to think it has something to do with samsung's software version. *stubborn me* lol. Since my warranty is super void now, currently flashed custom rom. Will observe if the problem persist. :good:

How can you downgrade the 910c to 5.1.1?

Facing the same issue. Got a new battery. Its no different.

I'm on an N910C using 6.0.1 (have also been on 4.4.4 and 5.1.1) and have never experienced this problem. I never use fast charging, always wireless charge and occasionally via USB. Recently got a new Samsung battery directly from Samsung UK (my old one was 18 months old, still performing well but not quite getting my usual 6hrs SoT any more, so it was time for a replacement). The new one charges to 100% every time (whether the phone is on or off), and drains down to 1% as you would expect, with no 'jumps', before shutting down - not that I do that regularly, because as far as I know that's not a good way to treat lithium ion batteries. To eliminate battery itself as the cause, I would recommend getting a new battery direct from Samsung to make sure it is genuine, or perhaps try an Anker.

Thank you. I assume this is done on Odin right?
What about the bootloader & modem?
Haven't used Samsung phones since the days of Galaxy S2.

s7 battery problem

I just got my s7 and use for a week. But the battery of my s7 drain very fast. And I can't use other charger to charge except for the original charger. Anyone has the same problem? Is my battery faulty or is there any fix for tat?

I thought the Elephone s7 didn't come out yet, how did you get it?

Bought mine preorder 3.Nov
This is my fifth day with my S7 runs like a charm except some problems regarding incoming call

When you say drain fast, what do you mean? What screen time are you getting? What's the issue with incoming calls?

I have the S7, 64GB and I also feel the battery drains quite fast. Around 3 Hours screen on time.
Currently trying with disabling the 2nd SIM & also turned the performance setting to low power and but has not made much difference yet.
Also I suspect the "Clear background App" setting/system app is unnecessarily killing apps in the background and causing even more app-restarts. Any way to turn this app off and instead use Greenify ?

I use my s7 five days and it was fine, tonight phablet did not respond to pressing the power button, left display off, I pressed multifunction button to wake up the device, but nothing happened. I attached charger but after an hour of charging phone is always off. I took away the SIM card and SD memory card and charging unit remained, and after another half-hour phone is always turned off and does not start anymore.
for five hours phone is dead but feels heat in the area of ​​the rear camera ... I think the problem started from the battery, because the same area was heated slightly during charging.

I have got the same problem, the battery is running down too fast. I only have used since last 3 days and I have to charge the battery twice every day. Any solution?

Hi,
No troubles here, battery is fine on my 3G/16G.
Do you have the problem when the phone is as new and wiped out clean from the recovery ?
Can you try this withouth installing anything ?
Best regards

For me, at the end of the day, about 40% of battery left.
I turn the battery pref into low performance, and no problem for my use

I am a light user and I get only 8 to 10 hours with the S7.
I recharged from 12% to 44% in less than 20 minutes,but it seems to empty just as fast.
I have heard that you should let it run down,till it shuts down and then recharge it and that helps the battery life

i have exactly the same problem .. no answer from elephone

I had same problem with S7 Mini, turned out it was 'Play Services'
Check this link for details. https://forum.xda-developers.com/elephone-s7/help/elephone-s7-mini-terrible-battery-drain-t3560035

Try this.. Go to settings, clear background application,, check all the apps as whitelist. It turns out the phone usually clear background applications, its logic to save battery is by shutting off every app which is running in background, but by doing this, the processor will work harder to bring up every apps back to work which means more energy more energy consumptions.
And turn of your finger print scanner. I did these and got my discharge rate 1%/h in standby.

Moto G4 issues after latest patch of Nougat

Hi,
I updated my Moto G4 to Nougat last week. Everything was fine. Yesterday there was some 114 mb ota update. I downloaded it and since then I am facing two issues-
1. Whenever I lock the screen using the power/lock button on the side, the screens becomes black and white for a millisecond and then it gets locked. I haven't seen any other phone's screen becoming black and white for a tad and then lock. Is everyone experiencing the same?
2. The battery is draining just way too fast. 40% depletion since morning. I only used the phone to make two 4 minutes phonecalls. I did not install any new app or game. Any troubleshooting for this?
This is the build number etc.-

Though it's unrelated to this update, when I first got this phone last year I had the same problem with the battery. What fixed it was manually recalibrating the battery. If i remember the steps correctly it was something like: Let phone fully discharge, plug it in and charge it with the power off for about 8 hours, power it on and keep it on the charger for at least another hour.
I updated my phone to Nougat yesterday and manually updated to the same update you're on. I haven't noticed that black and white issue with the lock screen and, if anything, the battery life seems better than on marshmallow. Hopefully battery recalibration helps out. A factory reset may not be a bad idea as well, especially if it wouldn't be a big inconvenience.

The phone charges fully in under 2 hours, thanks to turbo charging. Don't you think 8 hours are way too much? The black and white issue is being faced by other users too-

No. The whole point is that the battery percentage is inaccurate. Here's a guide for you:
https://forum.xda-developers.com/android/general/guide-how-to-callibrate-battery-device-t3308554
When I followed this process I let it charge overnight before turning it back on. I also didn't use the turbo charging charger that came with it, but instead a 5 port Anker usb charger. Perhaps I wasted time, but it worked.

Battery draining is subjective to personal use. I never heard problems like this with battery. You should have a rough app, or more than one, that is affecting the battery. Try finding that/those apps with a battery monitor app.
You'll get more help if you ask in an appropriate thread in the forums rather then creating a new one on this topic. Just a kind suggestion.

I agree with OP, i bought this phone Feb 15 and im STILL having problems with rapid battery drainage even when not using the phone! updated the phone already how many times and im on the latest build 9.5.9.0. I tried a hard reset last night, erased everything just so i can test if battery will improve, and it sadly didnt, it was still draining the battery quickly even with only stock apps installed. I dont know wtf is the problem but im pretty pissed off as i paid 230 euros for it and i dont think i can return it or exchange it for another phone but ill try if theyre nice, i have 1 yr warranty, i hope they can do something. I mean what good is a phone without a proper battery? I dont want to have to worry about battery life all day everyday like im taking care of some infant..
Not to mention the other bugs im experiencing like:
-issues zooming in on photos in the camera app's photo preview button. i try pinching to zoom but it wont. it acts like i want to swipe left or right.. stupid. double-tap also not work.
-proximity sensor during calls is bugged, screen turns on randomly and does random stuff to annoy you, very nice.
-mobile internet (4G) sometimes doesnt work for reasons unknown... what good is a phone without internet? nothing, reading books i guess... not that guy
anyone else have these problems?
should i start installing custom roms see if that will change anything?
im convinced otherwise that my phone has a hardware defect since how is it possible that others with the same phone and build number say its working flawlessly and others like me still have this daunting battery issues? it doesnt make sense..

Try installing custom ROMs like AOSPExtended, plus, install a custom kernel: MetaPheonix.
My battery lasts for 2 days.
The only issue I face is that the display randomly turns on.
4G Mobile data work.
No issues while zooming in.
No battery drain.
AOSPExtended
MetaPheonix
This doesn't really tell anything, but my battery hasn't dropped a percent since 30 minutes ago:

About the ROM.
Hello there I'm new here.
Begging developer.
Question is there any rom updates released ?

I have similar, or even worse problem. My Xiaomi Mi A1 loses around 30% battery overnight WHEN THE PHONE IS OFF, it can discharge completely while off. When I bought it it was off. I changed the battery, the problem persists. What the hell is this? I have never experienced battery drain in a switched off smartphone.

The problem with his battery drain isn't due to rough apps.
This is a more frequent issue being observed in Mi A1 and most of the times it's due to a wakelock called "700000.ssusb" and no one seems to have a solution as to how to turn it off.

For everyone who has posted issues with battery drain, can you install a battery monitoring app - Gsam or Better battery stats and grant it sufficient privilèges? Once you do that, you'll be able to identify what is causing the battery drain, mostly should be a wakelock, if not we'll get to know what it is.

AkCullen, many thanks for your answer. I can't believe I bought such a crap as Xiaomi A1 with battery draining when the phone is off. I spent so much time on trying to do sth about this already that I doubt I'll ever buy any Xiaomi again. Anyway, many thanks for suggestions! I tried to choose "enable more stats" in Gsam (is this what you are suggesting to do, or you are speaking of other permissions?), but I cannot "grant access with root" (unable to get superuser authority= no root?) and alternatively the app asks me to connect to computer and enable some ADB, which leaves me clueless and it way too much for a non-information-scientist as myself.
Is there a manual way to deal with those wakelocks that a non-specialist user can perform, or I must ask for warranty service? I measured discharge rates and in 5 hours, when off, my Mi A1 loses at least 20-25% of battery charge....

Go with the second option. Connecting to a computer and running a command via adb. It's pretty simple, connect your phone to the computer, enable USB debugging in developer options, download adb in your computer (the simpler version which is about 2mb) and run a command that gsam gives you.
And this is only to narrow down the issue, not to fix it.
I've been dealing with this issue for the past couple of months and it's frustrating. The service center can't help me in here because they don't even understand what the issue is.

I've been having the same issues lately. I don't use my phone much during the day, I'd say screen on time totals 30 minutes. Some days when I plug into my charger at 1:00am I'm sitting at 5% remaining, and other days I could have 55% left. I think it all depends on apps being ran, for sure. I think the improvement happens when I reboot the phone before I take it off the charger in the morning. Also, clearing all the recent apps seems to help a little.
But I do think it comes down to Xiaomi to improve the state of their operating system, either through Android or by implementing something themselves. It's really easy to cause a drainage to happen and difficult to stop it without something extreme like a reboot. I've just made it habit in the mornings to reboot the phone and clear recent apps and rarely have an issue.

My A1 Redmi went on to last 4 hours on after upgrading to Oreo. But I returned to the Nougat and the problem persists. Is it a physical fault?
If it is not a hardware problem, does Nougat solve the problem?
