It is something you installed or something on your setting up the phone.
this phone battery is amazing , trust me it is.
I get screen on times , unthinkable to my previous phones with brightness way way higher
so.. just try to figure out what is eating your batt and why.
edit:
then again you didnt start your battery log with 100% batt
and your drain was due to a very phone cal (?) With screen off, but your network signal suck really bad, maybe is from there ? But even with low coverage I find it hard to imagine that drain.
But then again.. never had low coverage ..

Yeah I can assure you it's something in your settings that is giving you poor life. You didn't give much description of what they are so it's tough for me to help you with what to fix, or how much knowledge you already have. I recommend BetterBatteryStats and Battery Mix for starters.

Install BBS (Better Battery Stats) and find the rogue application that is causing battery drain.
Battery life for me is amazing. I get close to 28-30 hours with mid - heavy usage.

Your signal during this two hour call was awful. Keeping a connection while not using the phone is a battery sucker in these conditions. I imagine it is much more so when you are actually on the phone. I'd suspect that as the culprit, as the radio has to be pumped up to the max constantly, instead of every minute or so.

I had a note 2 on same network and never saw this kind of drain. I think this qualcomm chip is ****. In my settings my cpu was at 2.27ghz for 1 hour 43 mins! Why was my cpu maxed out while making a simple call.?

4.4.2 Battery Life

Just flashed, I can already see it behaving differently. Most notable it will not hold LTE in my house anymore (great).
I an tell you right now this will drain my battery faster its bouncing back and forth, back and forth.
Ugh.
Will report back with battery life.
I made sure I flashed with 100% battery to avoid any issues caused by this (it DOES happen, trust me, ask the devs who worked on the Atrix.)
Seems ok so far though, who knows maybe the radio is much better and uses less power. its been unplugged for like 20 mins and its at 99% with about 5 of those minutes in use. Not bad.

When my blue tooth is off it gets better battery than 4.3 but I can't really tell when BT is on...

My other phone's a Ferrari.

Yep, its been reported from various websites that KitKat completely borks battery usage, especially on Note 3's and Nexus devices. I've gone through three Note 3's as a result and finally gave up troubleshooting and gonna stick with Jelly Beat

Is battery life getting better over time?

When I first used the OPT, I noticed that it loses battery *in standby* pretty fast. Screen on time was good but just leaving it be would drain a lot of battery. I turned off LTE but also noticed that it often struggled with cell network quality (which usually makes a phone look for other stations etc. thus battery is used a lot).
However, today, after a couple of days of use and maybe 3, 4 recharge cycles, it seems a bit better. Is there a chance that this is an actual effect (it could be something very different). Do batteries also get better after some use or am I just biasing my highly non-scientific measurements here?

I've noticed this too. I think that this battery technology does improve its capacity after several charge/discharge cycles.

Correct but what about 100+ cycles... It start loosing its power.... What's the best way to keep a li-ion unit last longer? Any help or suggestions?

Good practice is not let battery overheat, like when you play and charge, also batteries don't like to be fully discharged try to keep at least 20% and start charging again

Short answer. No, worse.

6.0 users post your Android OS usage

Hi Guys,
Do I have an issue with my android os? Seems to be keeping my phone awake and downloading a lot over WiFi. I have no idea why, but I think it's killing my battery life. I am lucky to get 4 hours SOT.
Post yours for comparison

How did you update? Did you fresh install or update over lp?
Yesterday it took me 8 hours to use 7% battery

Yes true, the screen shots are from the same day and why would the battery percentage matter? the battery graph is to show how android os might be keeping my phone awake even when the screen is off.
it would instead be helpful if you could tell me what your Android OS usage is? Or how you get such good battery life?
I did a clean install using flashtool (wiped everything) with the RU firmware.

Do you have Google backup on?

Yes I did have it on. I have turned it off along with uninstalling Facebook and turning off google now. so I will see how my phone performs today..

I have the same issues. Yesterday my screen on time was 2.5 hours and the Android OS consumed most of my battery (more than screen) keeping my phone awake for more than 7 hours. I barley made it through the day

I performed a full software repair via PC companion and cleared the cache partition too. I am presuming it might be that because i am essentially "starting again" the phone has to re-adjust to my usage patterns.
But it should not affect the battery life by that much! I am so mad about this update.

my android os is 25% active
it seems like the radio mobile active bug is gone in MM, but we have now a "android os active bug"

Android OS and Android System eating battery on Nexus 6P

Hi everyone!It's my first time posting here. I have a problem where everyday I have been getting both Android OS and Android System at the top of my battery stats.
I am running the Android N Dev 5 and getting less that 3 hours of SOT. The phone is only 4 months old.
I have tried to clear the cache and only did a factory reset only once. The reset helps a little but then creeps back. The cache clearing doesn't make a difference.. Something is eating up the battery and I have yet to try to place it on safe mode and hunt for the apps which I find such a time consuming process.
I attached a screen shot of my battery stats. I unplugged it at 11 and connected to wifi, fell asleep and woke up with 85%. Left for work and that's when I started using Data. I see that there are dots at the awake even when was asleep. It's odd and frustrating as I expected to have good battery life on the 6P but was bellow average on 6.0.1 and with N was better but not great.
Its a new phone of just 4 months and am just so tempted to have it checked out.
Any suggestions on the software side of how to fix this battery drain ?
Thanks :fingers-crossed:

For what it's worth my 6P is behaving the same way on the N5 dev build. I went back to M and the battery drain went away. I did a full wipe then downloaded N5 again today, will update if anything improves. I'm not too concerned as the apps are not optimized for N, nor is this the final build.

Keep in mind that Developer Previews aren't designed to be daily driver ROMs and are exactly as they're titled - for developers to get their apps ready.
Flash factory images (all of them; Recovery, Boot, System, etc.) and after things have settled down - an hour or so after all the app install/updates are done, reset your battery stats and confirm SOT from 100% is still as poor as you said on DP5.
With PureNexus July23, the stock settings and kernels and everything that come with PN, systemless root/xposed, Greenify Pro, and using Tasker to disable mobile data while connected to WiFi (and subsequently re-enable Mobile Data when WiFi Disconnects), I get 2 days of battery life.

Hi everyone! Thanks for the views and help.
I went back to M and it's been great so far. Battery life is better than N and got nearly 4 hours of SOT on average.
But thinking of the apps and how they're not optimized makes me think that I should maybe hold back on the next N update till the apps are efficient and work well on it. It sounds silly now as it's still in beta but makes me cautious in some way.
Should maybe root my phone soon giving it more options.
Anyways thanks again everyone. :victory:

Until it is stable release, you can expect all kinds of craziness. It doesn't mean something is wrong.
Google most likely has a lot of debugging going on as this is supposed to be the last beta release.
Expect the public release to be much better.
