Help Battery life Discussion

I unplugged from charger around noon on Monday and I decided to put it back on around 1030pm last night. If I would have rode it out I sure I would have had 5hrs SOT.

In my review yesterday I vastly understated my battery life. I took the phone off charge at 6AM yesterday morning when I plugged it back in last night at 10PM I had 51% battery left and it said I had aprox 20 hours remaining so by my math ... 36hrs give or take on a charge... I'll take that all day long and twice on Sunday.

I had about 4 hours of screen on time yesterday.
 
My daily routine had me plugging my Nexus 4 in during my commute (45 minutes in the morning, about an hour in the evening ... traffic :mad:) And that was really all i needed to keep it charged. I've done that with the N6 and i don't think i've seen it drop below 70% all week. I'm going to have to relearn not charging at every opportunity.
 
I'm going out of town over the weekend, leaving mid-day tomorrow. I am going to see just how long it will go from off charger to dead. I am expecting to charge it sometime maybe as late as Saturday night, we'll see.

So what did you manage? How much screen on time?

I soooo close to ordering one I'm just concerned about battery life.

Sorry for no update! I totally forgot about this post. I took it off the charger Friday morning at 6AM we left for Oklahoma City about 2PM. I was using the N6 to stream my Google Play Music most of the way down, I also used Nav once we got close to the hotel. We got settled into our room about 7:30, went and got dinner (used the N6 to find a local pub). Back in the room by 11:30. It was at about 45% by then. I didn't plug it in since I had my battery pack with me. (It was mated with my Moto 360 all day as well FYI)

Got up Saturday morning at 40% used it to navigate to a couple of places my wife wanted to go, as well as a nice lunch spot. (If you like craft beer and good burgers I highly recommend The Garage in Edmond OK) It got down to 9% by 1PM Saturday so I hooked up my battery pack. I had about 4 - 4.5 hours screen time, but was running many services over that duration.

So I got about 29 hours out of it, and that's including being out in the boonies in Kansas with some spots of no service and some spots on HSPA+ and some on Edge. And of course using the phone. It was not idle except for the 7-8 hours I was asleep.

I would not worry about battery time. I've been very pleased.
 
The one thing I noticed using navigation is that this phone doesn't get nearly as hot as my N4 did (or any of my previous phones, for that matter.) With my other phones, even though I had the thing plugged in to a 1A charger in the car, it still showed some battery drain after an hour of navigation with the screen on. And the phones would be very hot. This phone will actually charge (albeit very slowly) and stay comfortable to the touch. I am thinking it has to do with the Motorola radios not needing to amp up the power to maintain connections. Either way, I'm loving it.
 
Yea she never got hot even streaming music for 5 hours. Course I did not have it on the charger. But even on my turbo charger it never get's HOT like my Moto X would. It seems to handle most tasks in stride, doesn't have to work so hard so doesn't run hot.
 
Interestingly battery started off reasonably well, but today's not been good.

Currently got stats showing the following

Whatsapp - 7%
Android OS - 4%
Screen - 3%
Android System - 3%
Wi-Fi - 2%

55% 9 hrs left with SOT of 30m 9s

Every now and then an app or process gets stuck and you'll see this sort of thing. Rebooting usually fixes it.

Yes lots better today. Did reboot yesterday but didn't make much difference and whatsapp was still showing. However after taking it off charge this morning it cleared and at the moment I'm on 23% with 3hr 10mins SOT with whatsapp not even listed
 
You have to charge it to 100% to clear old battery stats. It might have been incorrectly reporting whatapp.
 
Picked up my N6 at the beginning of the week (purchased at Verizon and running 5.1). Noticed some unexplained battery drain. After much googling and testing, it appears there may very well be an issue with Lollipop and wifi that prevents the phone from sleeping sometimes thus causing a faster than expected battery drain.
 
I leave WiFi on 24/7 and haven't see this problem. I'm on 5.1 as well. Did your phone come with 5.1 already installed or did you update it?
 
It came with 5.1 installed. Funny thing is some people have the problem, some don't. Some say the Fit app (or some other app) is the cause, others say it's not. Some say it only happens at their workplace and not at home. I've also found reports that it fails to sleep after being unplugged from a charger but will be ok after a reboot. I've witnessed this once so far.

Here is one place I found a good discussion about this:

https://code.google.com/p/android/issues/detail?id=80274
 
Charlie:

That discussion focuses on an issue with Lollipop on the Nexus 5. There are a lot of issues with Lollipop on the Nexus 5. Fortunately, with the Nexus 6, there are relatively few issues.
 
I thought 5.1 would solve some battery issues I was having, but it seems to only have moved them.

My screen has been on for 2.5 hours today, and at 10% it's only the SECOND biggest consumer of battery life... After Android OS at 11%.

Android OS has been busy:
* 36m+ CPU time
* 10m+ keep awake
* 2h+ mobile radio active
* 3200+ mobile packets received, 16000+ sent
* 8200+ Wi-Fi packets received, 5400+ sent

I'm not rooted (nor do I care to be, really) so I don't have a lot of fine detail, but GSam pegs Android System at 9%, and Kernel at 5.2%.

This seems awfully high. What is the OS doing? I feel that I've made some battery saving changes, like limiting location to Device Only, turning off Wi-Fi when unneeded, etc... But it doesn't help much.

This has persisted through multiple reboots and factory resets. Anyone else experienced this? Any resolution?
 
Found what was causing the battery drain. One particular app was preventing the N6 from sleeping. It's called APOD (Astronomy Picture Of The Day) and I was using it to set the background picture. Once I deleted that, the the phone slept as expected. (Except for the wireless at work which wants to keep it awake a lot of the time but there's nothing I can do about that. Wireless at home is fine.) I was able to locate the rogue app by using the app Better battery Stats to watch wake and sleep times. I'd go into settings-> apps -> running and kill one app, let it sit for 30 minutes and then check the sleep/wake time until I found the one that allowed it to sleep.
 
I usually switch phones every 18- 24 months except last 1 1/2 years I have owned the note 3, LG G3 and now Nexus 6 under AT&T next plan.. In 18 months or whatever remaining balance I owe I can get another phone... I don't care for lg and hauwei isnt established enough for me to get the nexus 2015 and I really love my nexus 6 !!!
(TWO PART ?)

So what is the average life span of a battery and what would it cost me to replace it 
 
Hi guys, I've been recently having a battery-related issue with my Nexus 6 and was hoping someone could offer suggestions. Recently... let's say the past week or so... I've noticed the battery percentage drop quite significantly while using the phone for light tasks such as Words With Friends, web browsing, phone calls, etc. For example, if I start out at 100%, it will drop to 80% with only 15-20 minutes of usage. I put the phone to sleep for a while and when I wake it up, the battery percentage is at 90%. If I pull up the battery chart, it shows the severe drop AND the increase. To me, that means one of two things:

  1. I have an app that's screwing with the battery percentage so it's not being accurately reported.
  2. The battery isn't holding proper voltage under load, so it "rebounds" once the load is removed.

As a result, the battery graph looks like a mountain range. To troubleshoot, last night I booted into Recovery mode and cleared the cache.

Has anyone seen this before? Any suggestions? I don't have a screenshot as the phone is only a couple hours off the charger, but if it continues to do it I'll post one. Thanks!
 
I'd say you're on the right track w/clearing the cache via recovery.
If that doesn't do the trick,start looking at your downloaded apps.
 
Clearing the cache didn't fix the problem. I started out with 100% battery this morning, it stayed at almost 100% until I used it for about 20 minutes at lunch, and it dropped to around 76%. I put it to sleep and just woke it up to check the phone and now it's back to 100%. Also says "battery data not available". It's not been charged since this morning. The lack of battery data suggests to me a software issue so I will start uninstalling apps (with a reboot in-between) to see if that fixes the issue... unless someone else has another ideas?
