Hi guys
Just wondering if anyone else has noticed high battery drain on LMY48M?
Since the update my battery doesn't seem to be lasting the day if I have mobile data on and I use it occasionally. Basically unplug at 7:30am and by 3pm I need to start charging it. There's no obvious process draining it.
I did replace the battery 5 weeks ago and was working fine. Well into 20+ hours with use. Then not long after the update I noticed this issue.
Any thoughts on what could do?
Edit: Should have used the search (noob mistake I know) it's obviously an issue most are seeing on this build.
Are there any recommendations on Kernels to switch to, seraphore (sic) I've seen mentioned.
I'm always wary of updates in case something detrimental happens, but I recently updated to 48M and have seen no adverse effects. Phone on since 6:30 and still at 60%. Definitely no battery drain here.

Strangely enough it's behaving today. Had a SOD last night, cleared my cache and so far 12hrs since 100% and I've got 43% to go, reckons another 8 hours. This is with my usual usage.

Fingers crossed you've sorted it. 14 hours since 100% here and still have 45%. 12 hours to go. And to think I was considering replacing it with a 5X! [emoji50]

So a lot of people and myself over on the Nexus 6P subreddit have been discussing about the possibility of some sort of battery drain with the arrival of the Feb patch. On any ROM/kernel combination (and even on stock at some point), my phone very easily reaches 4:45-5:00 of screen time throughout a day that is from 7am-10pm for me. Over the last month, it has progressively gotten worse, on some days reaching low levels with just 3:30 SoT. After using various ROMs, I decided to try out bone stock to see if I would get the same result (this was 3 days ago). And that has been the case... The phone barely reaches 4 hours of screen time.
Well you might suggest: "Disable services such as location and sync" or "What apps have you recently installed that could be causing drains?" And that's the thing. My usage patterns have not changed at all. I barely download new apps and always stick to using the same ones. Today my location was off for a very long time and I've still gotten the same battery. I've been keeping my eye on the awake bar on battery info, and the phone sleeps as it should, so I'm sure there aren't any rogue apps.
I am seeing this as well. I actually went back to stock to see if it was the ROM I was using. Seeing the same battery degradation on stock. Running MMB29Q with Feb security patch as you can see from screen shot. Wonder if Google is aware of this. Cannot be a coincidence.

Haven't noticed this at all, I'm getting the exact same battery performance as I always have.
I haven't noticed any extra battery drain either.
I definitely noticed this myself.
I did a factory reset and it seems to have helped, but I've only tested it for one day since.

I'm with you. Same battery as previous factory image.

I have bought this phone in the beginning of February and my battery experience is TERRIBLE. It drained 20% battery in 16h with 17 mins SOT. I'm extremely disappointed in this device. I tried Stock, chroma and Pure Nexus and even when 0 apps are installed my battery goes AWOL. Really this is a nightmare where I paid alot of money for this phone and it acts like a personal energy waste device.

1.2%/hr drain isn't great, but not bad either depending on reception/installed-apps/notification/etc
I'm running 6.0.1 feb patch. Get about 0.6%/hr screenoff drain, but I'm mostly on good wifi connection. If running around town on LTE i'd get some where around 1% screen off drain.
I've noticed that ever since the Feb security patch, the battery has drained a little faster than usual also, with no change in usage behavior.... Can someone please notify google about this?
I have not noticed anything different.
Running stock with ElementalX kernel.
I've been noticing the same thing. I used to be able to go for 4+hrs of screen on. Now, 3.5 is normal. I am on PureNexus, but I've not changed anything in the last month, after the update.
I bought the phone on 28th February. 30 minutes after arrive at home, flashed Cyanogen, and draining about 1% each minute with screen on.
Yesterday I flashed PureNexus and now reaches 3.5 hours with screen on. Way better, but still terrible.
I've noticed the same increased battery drain. I've been investigating the issue for weeks and didn't know what caused the issue until hitting this thread.
The February update introduced the SystemUpdateService wakelock on my 6P. It kept the phone awake 95% of the time and I couldn't get rid of it. I updated via fastboot with the factory images at the time. I flashed back to the January build and the wakelock disappeared. Flashed the February update again and SystemUpdateService wakelock came right back.
I didn't try a clean install with the February factory images to see if it would fix it. Maybe it would have, maybe not. I decided to give Pure Nexus a try after I couldn't fix it. I'm considering doing a clean install once the March update is released.

Same battery issues as described for me.
I am glad to see that I am not the only one having a problem all of a sudden. I am running stock, but was about to root and run a custom ROM after becoming frustrated with the suddenly increased battery drain. I used to drop only three or 4% overnight, but now it is about 20%, with Google App being a prime user of battery even without OK Google being activated. Doze does not seem to be working as it did before. I am going to try shutting off Wi-Fi and Bluetooth at night to see if that makes a difference, but it never seemed to matter before leaving those on. Also, I do not see a way to automatically turn off push mail service at night or on a specific schedule as I could do with previous phones.
I'm glad. I thought I was the only one experiencing this.

Interesting - I have noticed that the battery life has tanked on my 5X fairly recently (been using it for a few weeks - will try on the 6P next).
Presumed it was just a rogue app or something, although nothing seems to be causing excessive wake locks etc. It is hard to quantify though, so it could just be looking for a problem where there isn't one.
I'm doing a clean install on my Nexus 6P from the March security update factory images, should be able to see if the battery life I'm getting is similar to January as I have a fair idea of what percentage my phone was usually down to at the end of the day.
A clean install of 6.0.1 with Feb patch and only stock apps. It's been sitting on my bed since a full charge 5 days ago. Looks like the Feb patch is not having much of an impact on battery life.
Is anyone else suffering this? I received the update last night on BTU S7 Exynos. Since then battery life has been horrible. Draining at 10% per hour roughly. Less than 30 mins screen on time and I'm at less than 30%.

I Noticed that as well. I thought i'm being paranoid. I'm flashing back to the initial BTU ROM!
Which BTU have you guys found has the lowest idle drain?

What is btu?
it's the CSC (Consumer Software Customisation) code for the UK - or at least one of them.
Different branded carriers will have their own CSC.
slugger, did you try a factory reset after the update?
you should be on around 80 - 90% battery
After the OTA april security patch I tried to wipe my cache partition and now it seems to be working fine
For me, wiping cache didn't helped me much, still got 8% drain during the night ( 6h ).
Gonna try a factory reset and see how that goes, otherwise i am going to reflash the firmware from Februari....

same thing happened to my end after latest BTU update, horrible idle drain. not to forget the misaligned toast message display at the bottom of the screen..
Today I suddenly got 6 hours of SoT! And this on my usual all stock unrooted 7.1.2 setup with my usual usage. Nothing updated or changed.
I usually get somewhere between 3 and 4 hours.
What is going on here? Is the SoT parameter buggy?

Maybe an app got updated? Or Google play services?
Yeah, maybe. Got a couple of updates yesterday, but nothing to do with Google.
Will be interesting to see what SoT I get on next charge.

Did u charge your phone halfway through the day and completely forgot? Lol or maybe it never reset the sot from your last charge. It's weird for your phone to randomly double it's battery life even if an app got updated or whatever. Battery size is still the same.
Wasnt able to upload pics, but my day has been terrible. 7h total time, 1h30m SOT, down to 30%. don't feel like doing a reset this close to Oreo.
