Nexus 4 signal and battery problems - Nexus 4 Q&A, Help & Troubleshooting

Hello there,
So, I had my phones screen repaired a few weeks ago. For the last two 2 weeks or so, after the phone loses about 30% charge it will start losing signal and then regaining it and this will occur for about 5 mins and then the phone will shut down weather its at 15% or 70%.
After this, everytime I reboot the phone it will turn off within 20 seconds even though it will still have plenty of charge on it. However, It is a dirty shut down. It won't say phone is shutting down, it will just turn off instantly
The only way to solve it is to charge the phone. It will say it still has charge once I put it on charge and that the battery is not fully drained and once it reaches a high enough percentage (e.g 80%). I will be able to use the phone till it drops round about another 30% and the cycle will begin again.
I have tried switching to multiple ROMs and wiping everything of course so it must be a hardware issue. Do you think it is a dodgy battery? Or what could be causing this issue? Any help would be greatly appreciated
Thank you

Another critical bug on the universal :-(

I just found another painful bug....this one is related to charging (battery). I normally put my qtek on charge all through the night when I go to bed. For the last 4-5 days I have been unplugging the device when it showed 100% charge, put it on standby (no wifi,btooth,gsm etc.) and made sure there were no applications running. I usually leave it in the standby state for 2 hours while I finish my morning exercise.
whenever I return, I see a power loss of 20%!! I was shocked to see how I could loose 20% in 2 hours ith my device on standby mode. this time, I even made sure I pressed the power button before I closed the lid, and still...no luck :-( I still lost 19%
I guess the problem is, when the charger is connected and the battery gets completely charged, it stops charging further. I guess it reaches a fully charged state within 2 hours, and the battery starts to drain all through the night...and wm5/htc don't start charging once again when the levels go down....i'll have to do a cuple more tests until I can totally confirm that this is the bug...until then, are anyone of you guys experiencing the same problems?
Another thing I forgot to mention, once again I charge my battery from 80% to 100%, and it lasts through the entire day(12 hrs) and drops to only 40% with highhh usage (bluetooth ON throughout, gsm on with 3hrs talktime, and some light gprs usage). so it really is not a problem of my battery as I see it!
Cheers,
San
Hmmm. I hate to say, but I don't see that problem. But I do have the unlocked JasJar Universal from HTC, not the qtek. If this happens with other qtecs, maybe they load a custom software that is acting up. In fact, I could leave the device on for two straight hours off a 100% charge and I don't think I'd lose 20% unless the phone was on too.

have you tried charging your device for well over two hours before unplugging? (around 8-9 hours of charging for instance?)
I don't really think it has anything to do with the qtek rom/device. the qtek rom has the least ammt of customisations on it...
I still suspect that the charging process halts and it starts to drain the battery....but the os doesn't reinitiate the charging process once again....hmm
I'll have to wait till tomm before I can do another round of checking....tomm, I want to charge it....and before I unplug, I'd remove the battery and put it back and see what it indicates...I suspect that the power would have already dropped to ~80% by then...that's the only explanation I can think of at the moment....

Hi Dreamtheater!!!
I exactly follow you as far as charging is concerned and I hv a Jasjar....just to inform you...I started charging yesterday at 11.30 PM and just got up to see the charge..it is 100%...no power loss...

it shows 100% for me too...but in just 2 hrs, it drops to 80% which is weird! from then on, it drains normally...
I still need some time to nail the exact cause for the problem...hmm!

Hey dreamtheater, I charge my Exec overnite everynite just like you. Usually at least 7 to 8 hrs everynite, but I have yet to experience what you mentioned here. My Exec always start fresh from 100% and by the time I get home at nite, it will drop to about 70% so no, I'm not getting the batt drain issue like you do..
I did not experience any such behaviour with my Qtek. It charged fine over night and had 100% battery when unpluged.
Are you sure your's does not wake up for some reason after you suspend it?
Dreamtheatre, I charged my XDA Exec overnight (7 hrs) and after 2 hrs with GSM/UMTS radio on the unit lost 5% battery charge.
@DT,
You need to set the device to switch off after a specified time interval. This can be done by going to start>settings>battery>advanced and check the device timeout box. I usually set it to 1 minute.
Last night i was browsing on my JJ and fell asleep while doing so, IE and notes and inbox applications were still open. When i started, the battery level was 93%, i browsed for about 10 minutes over Wifi before i fell asleep. The device shut itself off and when i woke up the battery level was 82% which is prportionate to my 10 min WiFi use and probably 1 minute standby time before it shut itself off.
Try it out, i'm sure you will stop seeing the massive battery drain
Cheers.
Another thing. Contraty to what people think, keeping the universal's battery topped off improves battery life. Prevent it from dropping all the way to say 30% or so. You will notice the difference in battery life in just about a week or so
Another source of battery drainage i've found is when i'm charging my Exec from the USB connection on my PC - If I leave my Exec connected and put my PC into standby, it will literally suck the life out of the battery over the course of a few hours!
I think some of you have got me wrong...let me restate the problem...
I charge all night
Wake up with 100% charge
Pull off the charger
Leave it on standby for ~2 hrs (no apps running, gsm, wifi, all off)
Come back, and find a ~20% drop
Back to my findings now.......
Another morning, no luck :-(
It had 100% charge...I pulled off the battery, put it back in and restarted....still showed 100%, so I guess it really was fully charged after all. This time I turned off receive incoming beams as well....left it for a couple hours, and was disappointed to see 82% when I got back :-(
However, through the day I get excellent battery life....all day's use ends up consuming roughly 30-40% charge which is excellent compared to my prev xda2 which would comparitively loose all of it by eod. I guess if I park my device in flight mode it tends to start draining quickly....now that's my only available reason or cause that I can think of....
tomm I guess I won't put the device on flight mode and leave it just On instead. This is weird because its just me having this problem :-(
San
PS: I'm using the regular ac charger itself for charging...hmm
DT, I disabled PowerSave and switched off the GSM/UMTS radio on my Exec. After about 8 hours I had lost about 30% charge. So your 20% does seem high. It could just be the battery as loss of charge is not linear. Why not let it drop to say 60% and then do your test again. By the way there spare batteries seem to be available now for the Universal.

[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).

[Q] Nexus 10 Battery Calibration Off

I have this strange issue with the battery calibration.
At first i thought the battery was dying on me. It normally stay active to 35-44% and then the OS would just suddenly report the battery is dead and just turns off.
Then i just boot into TWRP recovery and leave the screen on. And it's able to stay on for another whole hour at maximum screen brightness till it actually dies.
I tried deleting the battery stats in the data folder and letting it drain to 0%. But the OS still thinks it's out of juice around 35-44%...despite the fact that it can stay on for another hour or so in TWRP recovery.
Is there anyway to adjust the capacity of the battery in the OS?
Hi,
When this happened to me (but with 20%), all I did was letting the battery drain and charge it fully while turned off. Don't know if it actually works, but it solved my issue. Give it a try .
Good luck,
~Lord

Funny, I had just about the opposite problem. It was stuck at 35-45% while charging, or it would only go up about 1% every 20-30 minutes. Sloooowwww. Same solution seemed to fix it--let it drain to shut-down, recharge with power off to 100%. It seems to charge faster with power off, but I haven't done an a-b test to verify.
So I just started getting this after the update to 5.0 on my N10.
Beforehand I never noticed anything, although its been a few months since i have used it till a really low battery.
But I updated to 5.0. Used it for a while, the OS registered like 70% battery and then instantly 0% and it shut down. So I booted to the bootloader to see and it ran just fine for a while. I got bored and booted it back up, immediately shut down.
I plugged it in and booted it up and it was a 0% for a LONG time before it ever registered as actually charging. Then it charged normally until it got to like 25% and then instantly to 100%.
Im hoping its just a calibration thing, I did a factory reset just to be safe but it still did it. I guess the next steps if it still does it after a few cycles is to install a custom recovery and clear stats.
Same thing here
I've got almost the identical issue as the OP. Tablet shuts off without warning around 35-40% batter. When I reboot it says 0% battery and immediatley shuts down. If I boot into recovery mode though it will stay on for 2-3 hours before dying. I tried this and then charged it to full overnight with the device powered down and still today it shutdown again around 40% battery. Tried a battery calibration app before too but nothing has fixed it. This is 4.4.4 stock rooted with xposed. Been happening for about 2-3 weeks now. I'm pretty sure it's got to be software related right?? Anyone find a fix yet?
Just posting to say I'm seeing the exact same thing. It also just started happening since the update to Lollipop. It is shutting down at about 30-40%, then when I turn it back on it is at 0% and will shut down immediately unless it's plugged in. However, like the rest of you also said, in safe mode it'll stay on for a while longer without being plugged in. We really need a way to calibrate the battery somehow. This is a very frustrating problem. No warning at all!
I also have this problem.....this updates are so bugged.....

I have the exact same issue
After a full charge it's saying I only have three hours left on the battery. Battery life is really poor. I'm not sure if the battery is worn out (I've had the tablet since it came out) or if it's from the update.
Same same.
Just had the same start yesterday. Was charged to 100% ran a high intenssity game for an hour (makes my cell phone heat up and kills the battery like mad) but it was NOT affecting the 100% charge. I thought 'thats funny' then it started to go down some then it hit about 55% then BAM. Drops to zero and shuts off.
After that it would not take a charge no matter what I did but then for no particular reason except I was lazy and didnt wanna have to boot it up again after I plugged it in, I left it plugged in and went to take a nap. Came back an hour later and it had charged to 43% after having been at zero for about 20 minutes after I left the room.
Now its stuck at 43% and wont charge any higher. I'm leaving it alone for a few hours to see if it will ever get to 100% then ill run it down to zero then charge it over night turned off to 100%.
Ive been reading this as a battery calibration problem and came across a HUGE variance on the net about what to do about 'that'.
Some say the charge to 100% drop to 0% charge to 100% will calibrate it. Some say thats old Ni-Cad tech and you shouldnt do that with the Lithium Ions. But then others say you should do it with the Nexus 10 because it DOES calibrate the battery and that the tablet software protects the battery from actually going to zero%. (Saves a few percent and shuts off).
But then also someone else said battery calibration only works via a hardware change inside the tablet and that we are actually talking about conditioning. But then someone said conditioning is the max storage and that the 40% to 0% drop is not conditioning and since the charge discharge charge is for conditioning a Ni-Cad it wont help. Around we go.
There was also mention of a samsung PHONE having a problem with a bent usb pin inside the phone. But you had to pop the battery to bend the pin and since you cant do that a on Nexus 10 that doesnt help. (Plus the pin doesnt look bent to me even though about 30 people chimed in saying it helped them. But that was all phones.)
And finally. One website says you have to root the nexus 10 and use a batter calibratino app to calibrate it as option a but option b was some crazy combination of charge to 100 discharge for an hour, charge to 100, discharge for an hour, charge to 100, discharge till your aunts pink underwear falls off or something equally strange.
I'm betting based on you guys os upgrade bug. Just too strange. My 2 year warrenty ran out last month but I hadnt turned it on in six. Maybe thats a good thing. Be stupid to send it in for repair only to find out it was software.
Have to see if after my full cycle charge-discharge-charge it works again.
Prayin for everyone's devices. This sucks.

Suffice it to say I've been seeing this issue as of Android 4.4.4... NONE of the posted recalibration techniques seem to work and as usual, Google non-support is just as useless. As far as I can tell, once in this state it's here to stay... I've had my N10 shut down at 28%, 37%... even as high as 55%, and on re-charge (if I do it turned on) it charges to a point and then shoots straight up to 100%. I've seen the "takes forever to get above 0%" issue too... none of this has happened in any consistent fashion. I had hoped that friggin lollipop would solve this but instead they added a host of OTHER annoying bugs: as in after I restart it, the tablet goes into an optimization mode where it decides it has to re-optimize all 362 apps I have on the wretched thing. There naturally are a few others but they are beyond the mainstream of this evening's symposium....
Same exact thing is happening to me, but I'm on 4.4.
Same issue for me toosince 5.0 (now 5.1.1 BlissPop)
I'm gonna try to see if after my full cycle charge/discharge/charge it will work again...
Same issue for me too, since 5.0
Same issue for me too, since 5.0
to all of you how had had battery charging problems, please advise y you have used the "magenetic" charging cable. (It charge to a 25% higer rate)
I don't know how... I don't know why... After nearly 10 months of this behavior... I recently went through a couple of charge cycles (after it dropped to zero yet again) without letting it drop to zero.. AND NOW IT'S FINE!!!! I have no clue why... None of the stupid on-line non root solutions worked... I think that it's possible for this thing to recover after a random sequence of events which unfortunately cannot quantify because I had pretty much given up.

I am getting the same experience as most of you. Tablet shuts off at around 45% saying there's zero battery left. I assumed it was the battery going bad.
Sent from my Nexus 10 using Tapatalk
Well technically the battery starts going bad (yeah it's not supposed to... but nothing lasts forever) once you start running the discharge/charge cyle over and over again. To be sure my N10 is more than a few years old and while depending on use it can last a few days... it sure doesn't go quite as long as it did between charges as when it was brand-spanking-new. That said, and as said in my more recent post where I thought that the battery was borked, it now will last around two days with heavy use and about three with moderate use... and it now discharges appropriately to near zero warning me to connect the charger without just dying at 30-50 %... and the charge profile is a smooth curve from low to high with no sudden jog to 100% once the charge indication hits 60-65% like it did before. That would *seem* to indicate to me that this is far more a software issue than a battery one, and that purchasing a new battery may "fix" the problem but it won't FIX the problem! i.e. it'll only be a matter of time before it comes back. For all I know, some recent update to some google app took care of it...
After updating from CM11 to stock 5.1.1 I got the same problem. My N10 switch emmidiatly off at 70% battery. It was fine with CM11. Any news on this? Did a battery calibration, but this didn't helped.
I'm also getting this problem for the first time on the Temasek CM rom from 11/05/2015. It seems to have come up only since the 11/05 version.
Still no solution!?
I am having this issue (I think) since I received the update to Lollipop. So, basically it is a bit more than a year now. I was hoping a Marshmallow update would solve it, but: nope!
For installing Marshmallow I also did factory reset and all that stuff: it does not fix the problem...

Random turn off

Hi,
I have a Note 4 SM-N910C variant that is almost 3 years old.
Starting from 5 months ago the battery level would start dropping fast from 35% to 0% in like 2-3min after which the phone would turn off. If i took out the battery and insert it again, start the phone again it would show around 30% battery level. After a while it would start doing the same fast drops in battery level and so on.
I got a new battery, not OEM and now it doesnst do what i was facing above but it randomly turns off no matter if im doing something with heavy or no load on the device.
The turning off usually happens after the device goes bellow 50% battery level.
How can i test if all the components are ok other than the battery which seems to be faulty in my opinion.
I did order a new original OEM battery but it will take time to get to me.
I want to find out if the rest of the components are functioning without faults so i can decide whether i should get a new phone or not.
Please assist.
New battery
I know its not the same behavior, I have 2 note's. Mine is only a couple of months old while the one from my wife is build in 05/15. Her phone when we just received it would refuse to charge above 96%. Sure the phone would say 100% but as soon as you unplugged the charger it would drop straight to 96%. It did this on 3 different batteries, exactly the same behavior. All these batteries are OEM. When you plug it in it would go rapidly to 100%..
Anyway, I wiped the cache on that phone and since this it charges normally.
Been comparing the battery drain and both phones are using around 6 to 8% per night while on stby with wifi on.
Just try this, it may help you!
Thanks for the replies.
I did try wiping the cache and even did a factory reset.
I rooted the phone 2 days ago to try and recalibrate the battery but i didn't help.
I think the situation isn't degrading cause from today the phone is constantly hot and the cpu is running at around 48 celsius with 7-8% load.
I'll see what happens when the new battery arrives, maybe the phone is heating up cause of this maybe not. It's even eating the battery from 100% to 0 in 2h with no real load on the phone.
Do you guys think a benchmark program will force it to thermal shutdown if this is the issue.
I'm still trying to find out if only the battery is faulty or i have a dying phone.
To me you have 2 problems...a faulty battery and a (new) software problem on your phone.
Constant being warm with a cpu load tells me something on your phone is running all the time consuming your battery and causing your phone to heat up, unless it behaved the same before the factory reset and rooting?
You are rooted so try Wakelock detector for root to see which app (if any) is causing your phone to behave like this.
I will try wakelock to do its thing during the time i sleep. But if that doesnt help ill try a custom rom. Im not gonna factory restore and go back to stock rom. Gonna move away from that and see what happens.

Is my battery b*ggered?

So for the past few weeks my battery has been draining faster than the speed of light. It will get to anywhere between 30 - 70% (usually about 56%) and it will just turn off. Like straight to dead, no powering down.
When I try to turn it on again I get a white screen with a picture of an empty battery.
If I plug it is, I get the charging screen showing a battery percentage the same as it was when it crashed.
I've done a factory reset, wiped the cache, tried it with no third-party apps, all sorts. But it's still the same. I'm having to charge it 4 or 5 times a day and it's only getting about 30 mins of usage before it dies.
It tends to happen the most with the camera or Snapchat but I don't think it's related to those as it will also do it in other apps and even the lockscreen.
Is it time to call it quits and send it to the phone shop in the sky?!
I had this weird problem with my battery too! MXPE on stock nougat , as soon as I charged my phone to 100% and plug out it used to drop below 80 in 2 minutes ! and then when the percentage hit ~20% It used to turn off showing that white screen you mentioned, however when I plugged the phone in it would start charging at ~15% ! so I tried recalibrating my battery and it is surprisingly effective !
here is the method:
1) drain your phone battery until it shuts down.
2)power it on again and you will see that white battery low picture. plug the charger for 3 or more seconds and out, it will boot up again but as soon as the Rom boots up the phone will die again . do it multiple times.
3)charge the phone while it is off until 100%. turn it on and drain the battery as fast as possible (max brightness, volume, streaming videos on cellular data and running benchmarks will do ) till the phone dies again.
4) repeat (2)
5) charge the phone up to 100% while it is off ! and there you go your battery is recalibrated and good to go!
Obviously, this will shorten the batteries lifespan but since I believe you have it for a long time It won't be an important matter!
Thank you. I think I'm going to bite the bullet and treat myself to the new OnePlus 5T when it goes on sale tomorrow but I will try your advice as this will be a good backup phone to keep for emergencies as it's not worth much to sell on or trade in.
Try removing the back with a heatgun and unplugg and plug de battery.
I'm having the exact same issue and tried the same solutions, no help. It's dying now after a couple minutes. I'm carrying around a battery pack.
Seems to me my troubles started after updating to Nougat. You?
