Battery on 5.1 for me is horrible even with a custom kernel. 80% of battery and 1h SOT on wi-fi --" before i would have around 2h of SOT. What a load of crap
[Nexus 6  General] jbdan:
My battery life is better on 5.1. Not a lot but still better. I'm stock no root unlocked encrypted on 5.1. Battery life for me on 5.0 was great too. Beginning of this thread
[Nexus 6  General] ss12108:
I don't know if all of you loaded 5.1 as an update, but I went full wipe fresh install of the factory image and my battery life is definitely better. I'm not going to post stats or anything but I usually unplug in the morning for work and get through the day no problems but charge overnight as I'm usually low by 11 or 12. First day on a full charge after the wipe and 5.1 factory image I fell asleep early and didn't charge overnight and got another full day of work and was at like 15% around 7pm. Whether that's good or bad for the rest of you I'm not sure, but I'm definitely getting better, more even battery drain now.
[Nexus 6  General] PunishedSnake:
Did the straight to unlock and flash 5.1 factory image with my replacement. Battery life seems a little better but I'm still on my second discharge. WiFi still seems to drain faster than LTE/hspa though
[Nexus 6  General] erapmicks:
My battery been worse since 5.1. Bad is bad
[Nexus 6  General] INGfusion:
for me 5.0.2 to 5.1 calendar storage still cause alot of wakelock :crying::crying:

stock 5.1 + stock kernel + rooted & stock 5.1 + franco kernel + rooted = same result calendar storage wakelock cause battery drain
[Nexus 6  General] suku_patel_22:
The biggest improvement in 5.1 regarding battery life is teh fix for sensor_ind. Its such a relief to finally see it go away.
[Nexus 6  General] Vahndroid84:
sideloaded 5.1 OTA on saturday morning. Done a factory reset at 11am.

Google Services keeps draining my battery more than the screen on. There's a MOBILE RADIO ACTIVE voice that seems to grow when i'm not connected to wifi.

This has never happened before on 5.0.1. Why the **** is now killing my battery??? It should have been better......Google services is now draining more battery than 1 hour of SOT. This is madness......

Anyone can help? Could flashing the stock via recovery solve my problem? :crying:
[Nexus 6  General] jayesh:
Mine was mixed at first. Did a dirty flash and battery life went into the crapper. A standard whatsapp call of 10 mins and a 15 mins skype video call + an hour of twitter browsing took it from 95 to 22 literally. So i recharged it and left it laying around for half a day. Gone by evening.

At that point i did a manual flash, wiped everything clean and started afresh. This seemed to fix it... as the cycle is still going on. I have used it for an hour of voice calling, an hour of whatsapp and 35 mins on skype. Push mail on outlook beta is running full tilt and Telegram groups are buzzing away.

After about 22 hours its at 31 percent, with around 3 hours SOT and other mixed usage. Will report back in a week and see how things stand.
[Nexus 6  General] DroidDavi:
I was really hoping 5.1 would fix battery life. I have a note 4 which is an good phone but i miss my nexus devices. I was hoping 5.1 would improve the battery enough for me to move back
[Nexus 6  General] Vahndroid84:
honestly...until i did the sideload of the 5.1...i was VERY VERY happy with my battery life. I reached 5/6 hours fo screen on time, trough 17/18 hours from the last charge. And Google Play service has never been a battery sucker. NEVER.

After the sideload Google Play Services acts weird...and it's draining more battery than the screen on.

I've just did a clean install...flashing the stock with the nexus root toolkit, wiped user data, and rooted. Hope that a clean install has solved the problem...however i have now rooted the phone...so i can be more accurate with what is causing the drain using BBS (something inside the google services for sure).

What i can assure is that it's not a GPS problem...
[Nexus 6  General] Lulhasafotn:
Let us now if you find out what's killing your battery! I have the same problem with Google play services but I'm not rooted so I can't see what it's.
[Nexus 6  General] __NBH__:
I still think there is a bug within android that reports mobile radio active time incorrectly when not connected to WiFi. I regularly get Google play services, XDA, calendar and lots of other apps with high times but my battery doesn't really suffer, deep sleep is good and the battery drains the same as on WiFi it's just the battery chart looks messed up.
[Nexus 6  General] Vahndroid84:
I've rooted for this reason. I will go deeper into this. But before falling in panic :laugh: i need to understand if the battery is really suffering or if it's just a crappy statistic of lollipop
[Nexus 6  General] BennyJr:
This happens on my n5, all i do is freeze google play services in Titanium Backup, then defrost and re-sign in. No more wakelock.
[Nexus 6  General] Vahndroid84:
Done as a test

I'll let you know If this has solved the problem

Thanks!
[Nexus 6  General] funkpod:
For me, battery is tons better on 5.1. I left school and it was at 80%! That's 7 hours in my wormhole for cell signals of a school. On a great day, I'd have like 60% before, max. No, I didn't hardly touch my phone, but that's OK with me when I still have 80% left after work.
[Nexus 6  General] kava1:
Anyone else battery draining quicker on 5.1 when watching a movie? On 5.0.2 a 1% drop would yield me about 8 minutes of playback now I only get about 4mins. I'm using MX player
[Nexus 6  General] Tzfardaya:
If you have the time, run a system monitor to check what cpu freqs are used by the two of versions... Odds are 5.1 is running at higher freqs with mx player.
[Nexus 6  General] kava1:
Wish I could do that. I already upgraded.
[Nexus 6  General] Tzfardaya:
Downgrading isn't difficult... Just time consuming...
[Nexus 6  General] Vahndroid84:
It seems that the "mobile radio active on" is now much much less aggressive than before. Yesterday it almost matched the time with wifi disconnected and 4g/3g on. Now it's just 1 or 2 min out of about half an hour without wifi.

The only thing i've done was to freeze the google play services with titanium and defrost it.

I'll continue monitoring
[Nexus 6  General] Mikegrmn:
Battery draining for Google Play is a known issue on chroma Rom. The fix for it is to use "disableservice" from playstore. Open the app, go to the System tab (for System apps) and enable and then disable "SystemUpdateService". This has to be done after every reboot as it doesn't stick, but it's been working for me ever since I found the Workaround. Hope it helps.
[Nexus 6  General] gogol:
Google added bunch of craps on Android 5.1, for example the Verizon backup app (package name com.motorola.android.buacontactadapter) which shows running, even though you are not using Verizon.

It cannot be disabled via normal way, Settings -> Apps -> then disable ...

So, I found the guide below to disable system app via adb shell:

http://android.stackexchange.com/questions/56620/enable-and-disable-system-apps-via-adb

Is this safe? I meant, will this affect future OTA update installation?

I experienced in the past, when I changed system files, installing OTA update will fail.

Thanks.
[Nexus 6  General] wietse1988:
I never update google play services manually, everytime I update it manually I get massive drain. Try to delete play service updates. And let the play store update services. This way the correct play services are installed. There is no real need to have the latest play services. So just update play services through the play store.
[Nexus 6  General] Vahndroid84:
This is my situation of today

really disappointing.

My phone is always awake

don't know what is going on. I have obviously always on, sync, gps, google now. But i don't think this is the whay they are meant to work. I've also a few third party app like facebook, but, again, it shouldn't behave like this
[Nexus 6  General] tybo31316:
Anyone still have Google Play Services at the top of their battery usage with 5.1?
[Nexus 6  General] DebianDog:
GMS is Google Play services in this thread or another thread is a way to fix it.

[Nexus 6  General] jbdan:
Only after upon 1st boot/flash
[Nexus 6  General] tybo31316:
I've been running a clean install of stock 5.1 since Saturday and it always has the highest usage. Maybe I'll reboot my phone and see what happens tomorrow.
[Nexus 6  General] jbdan:
Are you on E or D stock image?
[Nexus 6  General] biggiestuff:
I would look into the network you're on. Wlan_Rx wake is high. Google it to see what you can change on your network.
[Nexus 6  General] Vahndroid84:
This happen on both my WiFi and office WiFi

I think it's weird...or not? How could it be related to the WiFi network if it happens on both WiFi?

This never happened before on 5.0.1

---------- Post added at 07:40 AM ---------- Previous post was at 07:38 AM ----------

What does it mean?

There are different stock images?
[Nexus 6  General] DebianDog:
Yes D came out last week I believe E came out this week.

Sent from my Nexus 6
[Nexus 6  General] tybo31316:
I'm running D.
[Nexus 6  General] Vahndroid84:
What is the difference between the two?
[Nexus 6  General] DebianDog:
I saw a list somewhere of minor things but the important thing I noticed was the new radio.

[Nexus 6  General] Chad_Petree:
I'm running 5.1 and I got a little bit of over 4 hours of screen time with around 50-55% of screen brightness but I was only on wifi, which is kinda nice, but I still need a bit more , 6 hours like the galaxy note 4 would be amazing , I don't get it, that phone has almost the same specs as the nexus 6, only a screen that's 0.2" smaller, it cannot make that big of a difference, I would like my phone lasts me the whole day, I use it a lot on the train on the way to my university, since it's an hour trip ( 2 hours if you count the ride back home) I also use it as a dictionary in french classes, it's my music player, etc, still 4:18 hours it's a BIG improvement over my nexus 5 (and the nexus 4 before it) :fingers-crossed: :cowboy:

[Nexus 6  General] Vahndroid84:
It seems that the "E" one is for Verizon Nexus 6 models

did you flash it? any noticeable difference?

i'm downlading, i will flash it as soon as i can...maybe it will solve my wlan_rx_wake wakelock problems
[Nexus 6  General] DebianDog:
I honestly had no battery issues before. However, I had better battery with the Franco kernel then I did with stock . So when I upgraded to 5 .1 E I updated the Franco kernel right away based on my previous experience.

flashed it

i'll report news in the next days
[Nexus 6  General] DroidDavi:
I found a nexu s6 for a really good price on CL so i decided to jump on it. I havnt sold not Note 4 yet i need to see what battery life will be like. While i know it wont be as good as the Note 4 im hoping i can get though a day. Im running Chroma and Franco hoping to see good results
[Nexus 6  General] Vahndroid84:
I did the same as you...but i didn't wait to see if the battery was worth it ( note 4 was just a try....i don't like samsung...in fact...i don't like what is not vanilla android :D )

And...again, until i was on 5.0.1 i was super happy with my battery life, even if i couldn't reach anymore the 7 hours of SOT as i did with the note 4...i was able to reach 5/6 hours through a "day" of 18/20 hours.

I really love this nexus...i think this is the best nexus ever for me
[Nexus 6  General] DroidDavi:
Ive used every nexus so going to the Note 4 was a huge change. Even after i rooted it and put a stock rom on it i didnt really like it. The buttons killed me to be honest.
[Nexus 6  General] Vahndroid84:
LOL

Same as me...i hate them with all my heart. I don't really know how people could like those things...they're even laggy :D
[Nexus 6  General] Red.Man:
After upgraded to Android 5.1, "Android OS" always keeps my Nexus 6 awake when it's connected to a Wifi. This make "Android OS" is usually on top of battery consumer and it kills my battery. Anyone experienced this problem?

I'm considering update to LMY47E build, and hope that Google has fixed that issue with the newest update.
[Nexus 6  General] Tzfardaya:
Grab a wakelock detecting app to see what exactly is holding your phone awake... I've used both d and e exclusively on wifi and have had no heavy android os drain.
[Nexus 6  General] Vahndroid84:
me too

but I have a problem with the wlan Rx wake wakelock. Google services and android os seem to stay at the bottom of the list this time

but I've that wakelock that is making me going mad.

I think that flashing a new image cause sometimes weird behaviors without any reason.
[Nexus 6  General] Tzfardaya:
Redownload image, verify checksum, clean flash using the included flash-all script... [emoji14] then trial it before adding any other mods.

Although, iirc wlan Rx is network based... Busy networks, congested areas, and sometimes misconfigured routers cause it.
[Nexus 6  General] Vahndroid84:
already tried

I've even done a test without installing any app. Only the packet sniffer...what I see is that there is a Google sync always sendin and receiving packets
[Nexus 6  General] Tzfardaya:
So disable/reduce what syncs...
[Nexus 6  General] Vahndroid84:
its not easy. I've tried disabling all the thing that sync with the google account

but it was still sending data

I think that is something underneath the surface. tried disabling google now and nothing...
[Nexus 6  General] Tzfardaya:
Grab a wakelock detecting app and dig further.
[Nexus 6  General] Red.Man:
I know but I just don't want to root my device..
[Nexus 6  General] Vahndroid84:
Done

i'm using BBS and Wakelock Detector and i'm still monitoring
[Nexus 6  General] Chad_Petree:
What exactly do android OS and android-system do ? Why are they using 3% and 2% of my battery respectively ?
[Nexus 6  General] Vahndroid84:
My phone is on from about 2 hours and wlan_rx_wake wakelock is already at 23mins /16% of drain. At this rate, it will be at more than 1 hours in the afternoon

This is not related to wifi interference or router settings. Because if i disable wifi, msm_hsic_host wakelock (mobile wakelock) start to drain at the same speed of the wlan wakelock.

Don't know what data is constantly going out and in

really... i googled it...but found nothig...

i forgot to mention that i have a moto 360 connected...but this happened even before. All started the last friday when i had the bad idea of flashing 5.1 ( i was in stock 5.0.1 from about 2 weeks, phone is a fresh new device bought 2 weeks ago)
[Nexus 6  General] italia0101:
I checked my device ... my wlan_rx_wake is quite high, but i'm still getting pretty good battery life :

Maybe you have something else going on?
[Nexus 6  General] Vahndroid84:
Thanks

could you give me more informations about your battery life? SOT? Total life?

I have a bunch of social apps running in background as facebook and whatsapp. But they are the same that i had with the 5.0.1. With that build i was able to reach 18/19 hours of total life of the battery, with a SOT near the 6 hours. Now it seems i can't go over the 4 hours with less total life...and i'm really pissed off...because 5.1 was supposed to improve performance and battery...not the opposite...

PS i forgot to mention that most of the time i'm on wifi (work&home) with usually 2hr at day of 3g/4g
[Nexus 6  General] italia0101:
Sure, so for my SOT you can actually see it in that screenshot i posted above, its the same as " PowerManagmentService.Display" so that was 1 h: 51 m

Total life i get normally is about 4-5 hours screen on time with a total time of 1 day 6 hours.

I have whatsapp too, normally i do have FB as well but i'm currently taking a break from all the " look at me i'm great blah blah " FB messages lol

The first few days of 5.1 my battery life was pretty poor, actually found out there was an app ( some sport app ) that just didn't like it at all, once i uninstalled that app it was back to normal battery life for me, so its possible that might be happening with you ?
[Nexus 6  General] Vahndroid84:
I don't really spend much time on facebook, in fact, sometimes i don't open the app for days. I mostly use fb messenger rather than the facebook app.

However...I have only gapps installed, whatsapp, facebook, facebook messenger, zedge for wallpapers and ringtones, and tapatalk. But as i said. Apps are the same than before flashing the 5.1 :(

Don't know what to do :(

I've already factory reset two times, tried to stay one day without installing anything but gapps... :(
[Nexus 6  General] Vahndroid84:
This is the situation as today. As you can see...my phone almost never goes to sleep
[Nexus 6  General] italia0101:
Noticed your signal strength went through a few fluctuations but yeah it does seem to be awake a fair bit.

Can you post the " partial wakelocks" page on better battery stats
[Nexus 6  General] Vahndroid84:
here it is

partial wakelock are not so huge in terms of drain

PS Meanwhile Google Services ha sends 10435 packets and received 6110 with a keep awake time of 10mins
[Nexus 6  General] DroidDavi:
yesterday was my 1st full day and the battery got me though the whole day. Which is from about 545am until about 10pm. A few of those hours it was off when i was at jiu jii jitsu. Im not to worried about SOT since mu moto 360 allows me to see notifications and i can just reply to text from my watch so my SOT tends to be low. But all in all im happy with the battery life. I didnt even charge during the day like i normally do i wanted to see how it would last without mid day charging
[Nexus 6  General] funkpod:
Maybe I spoke too soon.

Back to weird battery drain.

Does a factory reset help?
[Nexus 6  General] Tzfardaya:
Install a wakelock detecting app to find out exactly what is causing the drain.
[Nexus 6  General] funkpod:
Does this help? Not since charged, though. I can't find that stat.
[Nexus 6  General] Vahndroid84:
Don't know how problems are so random with android

Really...one flashes an update...and discovers to have ****ed up something just doing what is supposed to be normal with android. And there isn't even a solution. For me, factory reset didn't help.....
[Nexus 6  General] Tzfardaya:
Need to leave the phone idle for a while to check... You had the screen on for 30 minutes of that hour.. Charge it up, then leave the phone idle for at least an hour (the longer the better)
[Nexus 6  General] Kendaihou:
I got the 5.1 OTA update 2 days ago but it seems like it made my battery worse than it was on 5.0.1. I cant hit my 6 SOT anymore.

Hopefully it will settle out in a couple of days.
[Nexus 6  General] Tzfardaya:
Worse comes to worse, just flash the image from the factory image page...
[Nexus 6  General] bwheelies:
Mine is worse too. So is phone signal.
[Nexus 6  General] Tzfardaya:
So flash back to the older radio.
[Nexus 6  General] Chad_Petree:
Any input on this? :confused:
[Nexus 6  General] qqhorus:

My VZW Nexus 6 drained 45% overnight while i was sleeping. I checked battery usage and 20% of that was due to "Cellular Networks"? Any ideas?

[Nexus 6  General] plusforce:
I did not root my Htc m8

My sot was less than 4 hours.

yesterday I decided to do a factory reset from bootloader.

Today gsam battery monitor shows more than 6 hours sot.

it might be the same for n6.

I hope it works for those have little sot!
[Nexus 6  General] Damon13:
Poor reception can cause the device to use a substantial amount of battery life maintaining a signal and can sometimes cause frequent hops between cell towers. This, in itself, is a great battery drain. This can also be coupled with intermittent sync failures due to poor network connection, resulting in subpar battery performance. In settings under cellular network in preferred network type maybe you can change it to LTE/CDMA

Hope It helps, it takes time for Android to adjust a bit.
[Nexus 6  General] neyenlives:
Two day old VZW N6. I am quite impressed. Today was the first full day to test battery life. I use phone as alarm clock so I charge fully before bed and take off charger and stick under my pillow. After 5 hours alarm goes off. I snooze it for an hour every 10 minutes. Get up and it's at 98%. Been using it regularly this morning and streaming music over WiFi mostly to Bluetooth headphones. Now it's a full 12 hours since unplugged the night before and sitting at 74%. It's bone stock, rooted and bootloader unlocked. Only thing running that would impact this is the paid Greenify app but I haven't even added any apps to be greenfied yet so....
[Nexus 6  General] untouchablez:
How's your signal/reception? It's refreshing to hear someone report something positive about their battery life.
[Nexus 6  General] Tzfardaya:
I get crap signal, and my battery lasts a day of usage (4-7 hours of screen on time), with minimal "dumbing down" of my phone.. (lte, wifi, gps when needed, Google now always listening, etc, etc)

That's good enough battery in my eyes.. I don't need 3 days usage, just enough to get through. ;)
[Nexus 6  General] neyenlives:
I haven't noticed any issues. I also haven't been watching the signal much. I just have been using it like normal and so far there hasn't been a time where I was like "hey my old phone didn't do this"! Calls are clear. Both on Bluetooth and using it traditional. At times I feel like the phone ear speaker is a bit low on volume but haven't figured out if I am accidentally lowering the volume or not.
[Nexus 6  General] Tzfardaya:
Check you battery log, the signal history is in the histogram there, green is good, red is bad bad bad... (I've had a few "my old phone didn't do this, but the ones before it did" moments... But they were good moments.. eg. Put the n6 on a qi charge block to recharge)
[Nexus 6  General] neyenlives:
Lots of orange and red. Yet I haven't had any issues with it..... Tells me that histogram isn't an indicator of a real issue that effects things.
[Nexus 6  General] pathtologos:
Oh god. This is soooo depressing. I really, really wanted to keep the nexus 6. But I'd be so pissed if I went ahead and sold what I have now (where like one of you said, it takes like 10 -15 min for it to drop from 100 to 99) only to be disappointed tomorrow.
[Nexus 6  General] italia0101:
Yeah thats worse than my Nexus 5 , which drops about 95% with 7 mins screen on. i get about 2-3 hours SOT on my Nexus 5, am hoping for 4-5 on the N6
[Nexus 6  General] pgm8705:
Same situation here. Today is the last day I have to return the iPhone 6+ and I'm having a hard time doing it. As much as I love Android over iOS, the battery life I got on the iPhone was just so much better than this nexus 6 which is really no better than my old nexus 5 so far. I've had the n6 for 5 days now and battery life is so inconsistent.
