Google working on a fix for Nexus 5 battery drain
Suffering through poor battery life on your Nexus 5? A published report on Thursday states that Google is working on a fix to stop the battery drain on the stock Android device. The report claims that the battery issue is due to a software process on the Android 4.4.2 build of the open source OS that gives apps access to the camera on the Nexus 5. The process (mm-qcamera-daemon) opens to allow apps like Skype to use the snapper on the phone.

Even when camera apps are closed on the phone, the process continues to run which forces the processor to keep working, draining the battery. The issue also makes the Nexus 5 run hot. One person complaining on a forum said that with the process running, his Nexus 5 is losing 1% of battery life every 2 minutes while on standby.

A Google project manager wrote on the same forum that a fix will be included with the next maintenance update. He also blamed the Android version of the Skype app saying that an update to the app might have set off bugs in the "mm-qcamera-daemon" process. He recommended that those with the Nexus 5 delete the app.

While the project manager did not have a time frame for the update, he said that rebooting the Nexus 5 would be a temporary fix for now.

There are even more bugs which google needs to fix in the Nexus 5 such as the low exposure in low lighting and the hiss/static noise while video recording. Some people also have microphone related problems.
Common google just bring damm update. It has been almost 3 months that these important issues are not fixed.
Bring it on google

How about they fix the latent text, and no ring bug. The Nexus 5 has a bug that keeps it from ringing or receiving texts which Google knows about. They made 2 updates to address this bug yet it still exist. Android Police seems to be the only Tech site that has reported on this bug. This bug has been around since the launch. This bug affects all carriers which truly makes it a legitimate bug! I personally reported this bug the 1st few days after using this phone when they tried to dispel it.

Why haven't you guys reported this since it is of major interest PA!

Personally I haven't faced that bug or maybe faced it but never noticed it.
but yea it certainly needs to be added to list of bugs which google needs to fix.

All pure Android OS, including Google Play Edition always suffer poor battery life.

I don't agree with that at all. I charge my Nexus 5 every other day with no problems. It's been fantastic. And the experts agree with me:

The Nexus 5 battery life is not too good in general because it only has a 2300MaH battery, so hopefully they will put a beefier battery in the Nexus 6.

No Nexi in my house suffers from this issue.
Just pointing out, its a combo problem, 3rd party needed.

I found turning the display on before unplugging the charge cord works for me. My Nexus 7 (2012) stays 100% while not in use. I used to have the Dead Battery in the Morning syndrome, but not anymore.

I don't have this file running on my Nexus and it has crap battery life. Not sure which battery is worse, Nexus 5 or HTV EVO 4G from 4 years ago.

The Nexus5 was a complete disappointment. Hopefully Google will go with a different manufacturer for the next Nexus.

Do you own a Nexus 5?

Probably not. There have been articles that state that 4.4.2 has had a negative impact on battery life for various phones, including my Moto X, though I have yet to experience that. Though it's frustrating because this past update was stated to improve battery life.

I've yet to notice this issue as well, maybe it's because I have the phone off most of the day. Either way there's still issues with the battery life and I doubt they'll get much better through software.

I agree an also figure, if they sought ought a Nexus, they can also find ways to improve or squash issues an end user might have with it.
Maybe google should charge more for it lol.

Hindsight says to me now maybe its just the essence of a Nexus is lost to some.

Frak, no Knox, no htc hoops of old, just meant to be used.
Beyond most, who claim laziness and compare it to the likes of a $800 flagship.

Guys, something is seriously wrong with your phones software or network if you are experiencing poor battery life. This phone is capable of outstanding battery in the right conditions taking into consideration it's screen size and battery capacity. Some of you are no doubt experiencing the issue described in this article. While there are many things that can cause battery issues, there are two other issues that those of you that are having problems may also be experiencing.
First, your network coverage and signal strength may not be as good as you think. All you need to do is have a look at the battery stats that are built into the os. Check out the Mobile network signal color codes. If you are seeing green like grass, this is not an issue for you. Green like grass means you have a strong signal and your phones antenna is in a low power state. If you see red, you have lost signal for some time, yellowish means your signal is not that great and power to the antenna is being ramped up using more battery. I started my nexus 5 off on ATT and was very pleased with battery life on LTE. Switching to Tmobile is where I ran into issues. I had LTE coverage all around town, however I noticed my battery was draining much faster than on ATT, checking battery stats as described above revealed the problem. I switched the phone over to 3g (h+) which still gives 6-8mpbs down and 2mpbs up consistently in my area, and battery has returned to how it was when I was on ATT.
Your other issue may be location based services. Please make sure your GPS is not running all the time. For optimal battery life you may want to turn this and location reporting off. This phones battery should get most of you through a days use without needing a recharge unless you are heavy users.
Running CM11 I can consistently stream audio over wifi for 5h-6h, have 2h of screen on time, take some photos and still have about 30% battery when all said and done. I've also been able to get 5h+ of screen on time with browsing the internet via wifi which is consistent I believe with phonearena's testing.

I did forget the last and most obvious battery factor as I pretty much take it for granted. Typically I set the phone's brightness to around 25% for everyday indoor use. When outdoors I ramp it up, and when in bed down to the lowest. I do plan to do some more controlled scientific tests in the near future, but for now they are on hold due to a recent rom switch to PAC which seems to have a bug of it's own I need to resolve. I recommend all of you do the over night battery drain test. Even with several things syncing overnight, you should see only a few percentage points lost in battery.

I've noticed and the resolution so far was to turn Mobile Data off when I'm solely using wifi and it tended to last longer in the meantime

Now if they would just bring back separate notification and ringtone volumes, we'd be all set. Don't know why Google ditched that after Gingerbread. Yes, I know I could root and get that feature back, but it was dumb for them to even remove it in the first place.

As some of you probably know I have been one of the people having the problem with the phone (Nexus 4 with 4.4.2) draining the battery extremely fast even when I don't have Skype installed.

Since it is a sporadic problem (only do it sometimes) it is very difficult to notice that you have the problem until it is too late. You notice that you have the problem because the phone will overheat to a scary point (even when you have your phone in your pocket and you not using the phone at all) and will drain the battery from full charge to dead like in 1 hour. And it don't even want to charge the unless you turn it off and let it cool down a few minutes before trying to charge it.

But the good news... I upgraded "WhatsApp" and the phone seems to be working now normal again. No more overheating and back to normal (hours) battery life again...

"Hours" battery life is not normal for this phone. An average user should get through the day without needing a recharge. On standy on wifi you should not lose more than 0.4%-0.5%/h battery.

22. Professor (Posts: 223; Member since: 02 Aug 2013)

Now that the phone is working normal again I can be several hours (like 8 hours) actually using the phone (phone calls only. No games or Internet)...

When I was having the problem the maximum that the phone was able to stay on was 1/2 hour to 1 hour before the battery went from 100% charge to red-line or dead and that was without even using the phone (just stand-by in my pocket) and with the Wi-Fi off. Plus it was overheating drastically. (I even installed a brand new battery thinking that the problem was the battery).

Hopefully the drain battery problem don't come back again...

Unfortunately, it sounds like you still have a battery drain issue. 8 hours is definitely not normal battery life for this phone unless perhaps you are saying you literally talk on it for 8 hours a day. Most people should make it through an entire day without needing a recharge. I can help you work through your issue if you don't mind making a post on xda. I will also help anyone else who seems to think their battery life is poor and is willing to post the questions on xda as well.
