So I currently have a Nexus 4, and I'm waiting for my new Nexus 5 to be shipped to me so I can give the Nexus 4 to my wife.
I have two LG WCP-300 wireless chargers for my N4 and about 80% of the time you take it off the charging pad a wakelock keeps the CPU from going in to deep sleep. I then have to reboot the phone.
Does the Nexus 5 still do this?
If it is fixed, did KitKat fix the issue (i.e. will the N4 be fixed too) or is there some sort of hardware change in the N5 that fixed it?
Thanks!
I think the short answer is "no", but here's the long answer...
I've never had the wakelock issue that causes the phone to drain like crazy after it's been removed from a wireless charger, but the problem I do have is the wakelock keeps the phone from sleeping while it's on the charger. So my phone fully charges in a couple of hours when I go to bed, but by the time I grab it in the morning the battery has drained to 75 or 80%. Luckily I haven't had the issue where this continues to be a problem throughout the day.
I upgraded to KitKat yesterday (from factory image, without a wipe), but I had the same problem overnight. I kind of doubt it will help, but I'm considering wiping my phone to see if that will fix the issue. I'm hoping that whatever bug it was in 4.3 got fixed, but my lack of a wipe let it creep into 4.4. Unlikely, I know, but I can hope. Sorry for the bad news.
No wakelocks with wireless charging on my N5 to date, but I've only been through a couple of cycles since I got it on Friday. How often does it occur with your N4?
Yea, Google fixed the issue. I had it bad with the Nexus 4, but charging the Nexus 5 using the same Orb I have absolutely no issues.
haven't experienced this wakelock issue myself yet. Just got my wireless charger yest and works fine.
I had the wakelock problem with my N4 but have had no issue with my N5

I have zero wake locks with the N5 since launch day. Wireless charging I use every day. No issues ever.

OK - I've started using my Nexus 5 full-time and I'm using the wireless charger - a LG WCP-300, which should be high enough quality to be a "reliable" charger for the N4/N5. I'll report back if I have the same issue I had with 4.3 and the N4, as the results here seem to be mixed.

same problem here with nexus 4 and no change after updating to 4.4
the problem is 2 part
1) fast drain if the phone is left on the carger when fully charged
(if removed when full it will discharge much more slowly)
2) charging never restarts no matter how low the battery goes unless the power to the charger is interrupted
or the phone is removed from the charger and replaced.
forcing a reboot with tasker does not restart charging
I put the charger on an outlet timer that turns it off for 1 minute at 6am.
that restarts the charging so I can wake up with a nearly full charge.
this works. if you set the timer for 1-3 hours before your normal wakeup
time you're gonna have a nearly full charge when you get up because most
of the time the charger will not turn off for quite awhile after 100 charge is reached
and it will stay at 100% until the charger turns off (charger light turns to green from blue).
there may be other chargers that don't have the same problem.
mine is the round flat charger you see on ebay that comes with different color rings for about $22

I'm using the same charger, but I don't think this is charger specific. My girlfriend's S3 (which I think is on 4.2.1) charges perfectly with several different wireless chargers using an add-on wireless charging receiver.
Clever solution, btw. But it would be great if this would just work the way it's supposed to. :-/
This problem was there since i bought the nexus 5 (first week of jan), but it used to happen seldom, like once a week or so. But since last 2-3 weeks, everytime i try to charge my phone, it doesn't charge and actually starts discharging and reaches 0% in some time while charging, one way i have found to solve it is to switch off the phone while charging, let it charge like that for 5 mins, and then switch back on, it gains 1% during that time, after that it charges normally.
Using original charger and USB cable that came with my nexus 5, tried using samsung charger and HTC cable with HTC charger as well as OEM charger, doesn't make a difference.
Also, since i bought the nexus 5, if the USB cable is even slightly displaced (like when picking up the phone), and phone disconnects and reconnects from charging, like the port on the phone is loose or something, this annoys me while transferring data from pc as if the phone is even slightly moved, then the Internal Storage unmounts and remounts on the pc, thus interrupting the transfer. Though this problem i have noticed is slightly higher when phone charge is on the lower side (~20%) and if i try to fiddle with the USB cable while the charge is >60%, the problem doesn't seem to be that much, though it still disconnects, but not that sensitive.
Can anyone explain what's going on?
Does the mobile display that the phone is actually charging when you have connected it to the charger??
As for your second problem, I'm sure the micro usb port of your device has become loose... Nothing you can do to fix it... May be visit a local LG centre and tell them to see if it can be fixed by opening up the device and tightening it may be?

Yes, the phone says charging, battery settings says Charging (AC), but it doesn't charge, and discharges, i don't think that some app is using high cpu while charging, because my battery discharges fine before i put it on charge.
I purchased it from Play Store, so LG would fix it then too?

Are you fully stock? If so, then perform a factory reset and see whether the issue persists. If you're using a custom rom then flash the factory images and go fully stock and see whether it still occurs.
If it does, then it's surely a faulty battery we are looking at. Since you've tried using different chargers and cables, there's nothing more you can do.
Call google customer service and RMA it.

Yes, i am running stock rom with root, tried factory reset, no improvement, currently my phone is on charging with 71% charge, now i am using my phone, testing new camera app, no disconnections, but when i use the phone with low charge while charging, it disconnects and reconnects, don't know if it's hardware fault or just software, as charging too returns to normal when phone is switched off and then turned on.
Is RMA'ing the last resort? coz i am afraid that RMA might lead to some other problems, like getting a replacement with screen bleed issue or some else issue.

Yes, what you've said is very true. The replacement device might have other problems if you're unlucky.
Are you on stock kernel or have you flashed a custom kernel? If you have then flash the stock boot.img and see.
If everything else fails you can flash the factory images from Google and go completely stock and see if the problem persists.
It's upto you to decide whether you can overlook this weird battery issue or not. If you can't, then RMA is the only option left.

hmm yeah, i would need to think about it, thanks for the help.. :good:
i think i'd wait for 4.4.3 first to see if it isn't a firmware issue.
This results are from my tests.
If your current CPU operating temperature is higher than 51 degrees celsius the phone won't charge,it will stay at for example 50% .
If the temp. Is higher than 51 degrees the batt% will decrease.
If the temp. Is below 45 degrees the battery will charge but very slow.
If you're gaming it's normal.
Leave your phone to cool down for 20 minutes and it will start to charge at normal tempo,1-2% per minute at 20.degrees celsius.

Whattt?? I have put my phone on charging while playing heavy games like mc4 where the temp easily reaches 50+*c and I haven't seen any interruption in battery charge..
Are you sure about this??
Sent from my Nexus 5 using Tapatalk
In my case the battery isn't charging or it's charging BUT at 1 percent in 7-8 minutes when CPU temp. Is 51-52 celsius or above.
Sometimes when it's above 55 celsius,battery percentage is going down.
I'm charging with the original charger and cable.
I,m not using usb fast charge hack.

Yes, that's normal. It will charge if the temp is above 50*c..it will charge slowly as you are using your phone for hd gaming which takes a toll on the battery..
Fast charge just means that you can charge via your computer at AC wall charging speed...
If you charge your phone via computer and play games on it simultaneously then it's normal to discharge while charging as usb charges only at 0.5amp

ok, so after some days of testing, i can say that this problem is irrelevant of temps on my device, sometimes it charges without any nags, but most of the time it discharges while plugged in, and i have to reboot the phone.. :crying:

This happened on my last phone. For me, it was from using a USB fast charge option on a custom kernel: reflashed the kernel and charging was back to normal; selected the option and it duplicated the problem.
So:
Are you using a stock kernel? Either way, I would try wiping caches and flashing the kernel (or another one).
Or, if you haven't, try a simulated battery pull (hold down the power, volume up and volume down buttons for ~15 seconds).

I know when I'm using my phone as a sat nav on the car dash it can get pretty toasty. When it's like that, it is on charge but the phone will still drain slowly... so on a 3 hour journey it may lose 20% battery or something. That is with an official HTC car charger so perhaps the results are a little unfair - think it's rated 1 amp.

yeah, while discharging, no matter how many times i re-insert the cable, or change the charger or the cable, it won't charge unless i switch off the phone, let it charge for some minutes and then power it on, it'll start to charge normally after that..
I'm in a similar boat. Every now and then I'll wake up with the battery being only charged to 75 or so. Since it happens sporadically it's hard to test why it may be happening. Have you found any resolution for the issue? This is using a wireless charger so a bad USB port can be ruled out.

The Nexus 5 has a charging controller by TI, that regulates the voltage and current to the battery if the battery gets hot enough lets say 50C it will stop all charging untill the battery is cooled and the charging session is re-started
The battery also has a fail-safe measure to prevent the phones battery from exploding which also does what the charging controller does, incase it fails the battery has another fail-safe mode
I own a one plus one handset and its a year old.Since a mnth the handset is taking 4 hrs 2 charge instead of 1 hour 30 mins .I am using the og charger provided by the cmpny.Plz help!!
I had the same problem.then i changed usb cable that is 2.4amp cable then it's fine & faster charging...you should have to change cable or charging adapter

Try sultan rom, i used to face similar issue but once i installed sultan's rom it started working fine ( or if you have twrp recovery try wiping dalvin and cache)
or some one posted some temporary solution on oneplus forums , try this (i am copy pasting the same)
I encounter the same problem with charging time and input amp after Marshmallow update. I use Battery Monitor Widget app and notice that the current flow range from 500-900mah, which means only 50% from the adapter potential and make the charging process twice longer and at the same time the phone doesn't generate too much heat while charging.
I did factory reset, clean install the system, change the cable, format the cache partition but the problem still exist.
Later I found the solution,
1. Install the Battery Monitor Widget app to monitor the charging amp history.
2. Leave the phone charge for a while.
3. If the current flow only range from 500-900mah, unplug the charge adapter and plug it in again.
4. Leave the phone to charge again so the Battery Monitor app can record the charging amp.
5. Keep doing the same process until you get 1000+ mah.

Check if the power socket is proper also if the cable that you are using is not getting degraded. if so try with some other good quality cable and it should be back to quicker charging. Also as old your phone gets slower its charging will be due to chemical processes in a battery.
If you are rooted install Synapse app from marketplace . Go to miscellaneous section and change ac power level value to 2000 .
I have to agree with flashing another ROM.
Try jgcaaps' Marshmallow build from here:
http://forum.xda-developers.com/oneplus-one/development/rom-cm-12-builds-t3045053
Then download Kernel Adiutor mod from here:
http://forum.xda-developers.com/android/apps-games/kernel-adiutor-mod-singularity-kernel-t3333549
Set up the ROM then the Kernel mod next.
Run the Adiutor Mod and click the 3 line menu.
Scroll down to Power & Battery.
Change the AC Charge Level to 1800.
Change the USB Charge Level to 800.
These charge levels are ideal to extend the battery life. I hope this helps.
Try another decent cord. The cord I got with my oneplus power bank thing started charging very slowly a few months ago so I threw it away and started using the USB I got with my nexus 7. It works just as well as it used to now
