8.1 DP2 battery life - Google Pixel 2 Questions & Answers

On the stable 8.0 November security release, my battery would hang at 100% for sometimes an hour or two with minimal use, then drops like normal.... Since downloading the 2nd beta a couple days ago, it drops to 99% in a couple minutes and just steady drops like normal.
Anyone else notice this? It does drastically affect how long my battery lasts in a day.

I have the same thing as you.
I just opt out of beta and downgrade to 8.0

I checked into the forums today searching for mention of this very thing. It's too early to tell whether battery life is taking a hit with DP 2.

I noticed the same battery level behavior with my Pixel 2 where it hangs at 100%, I never did believe that it was supposed to do that. It sounds to me like the new 8.1 DP2 may fix it rather than break it. We need to check the overall time from 100% to full discharge to know which is right.

I'm having same battery life with DP2.
Still 1 day and 6 hours SoT average.

Agreed (although I never got the very long 100% that some report). It does appear that DP2 is better calibrated rather than is draining faster.

Battery is more accurate here since DP2
Before DP2 was draining slower from 100 to 90 and faster from 70 to 0.
Now it's more constant from 100 to 0.
Overall battery life is the same.

I can't complain so far. I just got another Pixel 2 yesterday and loaded DP2 out of the box. I have 2.5 hours of screen time and I'm at 57% from 24 hours ago starting out at 100%. It hung at 100% for quite a while here too.

Use adb to disable wifi on during sleep which google now enforces.

Update:
Battery seems to be lasting just as long, if not longer than before. I assume they just have a different way of calculating battery percent. I'm getting around 6.5 hours of screen on time before getting down to below 20%.

Foyo update...Battery life shortened ?

Has anyone noticed their battery life seems shorter since the update ? I installed the official froyo update last night and it seems I'm running out of juice much quicker than before.
At first mine ran down faster. I ran it all the way down. Charged it. And ran it all the way down again and charged. It seems back to normal.
I didn't have any issues. Maybe you changed something else as well? Could always try a few recharge cycles and see if it stabilizes..
I was running the leaked 2.2 and I flashed to official 2.2. My battery life is almost double what it was. I can't complain one bit about battery life, although I have other gripes with the official Froyo release.
I'm with icepop on this one.. I was running the stock rogers rom pre-update and now with the official rogers 2.2 I'm getting at least double the use before having to charge again.
I'm having battery issues with the new stock Froyo. I lose a huge amount of juce when in standby. I thought I may have my widgets updating too often so I charged it up and put it into airplane mode last night. The phone lost about 1% per hour in airplane mode. IDK what is normal but that seems like a lot to me. I didn't have any apps running, except my alarm was set for the morning.
I have SystemPanel installed and my cpu load NEVER goes below 10 percent, even in airplane mode. I suspect this is a large part of the issue. In app history, system and system processes are always on the top of the list and are around 3% each. IDK what controls this or how to lower it. I would love some feedback from someone else with SystemPanel just to see how our numbers compare. Overall the battery life I'm experiencing is pretty terrible and a buddy of mine's Fascinate has much better battery life (hence something must be wrong somewhere). He and I were skiing all day over the weekend and when we got back to our cars, my phone was half dead and his had lost almost zero juice. This displeases me.
mine's was better actually. but i didnt stayon it for long
My initial results with 2.2 were very bad (10% drop per hour when idling). I reset the phone back to 2.1 then re-installed 2.2. This did not help. Now I did this again (2.1 then 2.2) but this time I have not re-installed my apps and have not rooted (yet). So far, battery life seems to be normal. I suspect that some of my applications might mis-behave when installed on 2.2. I am planning to add them slowly and watch the battery.
Not here, seems the same to me
Mine is terrible ! I don't know what it might have been on 2.1 as I upgraded fairly quickly. Essentially I charge all night and then disconnect from power at 6:30am and then by 4:30pm I'm out of juice (phone shuts off). Any ideas here? I'm not running anything extravegant (email only) and hardly make any calls.
Whenever you flash to a new ROM, wait for at least a week of normal usage before you judge the battery life. The reason is simple, your battery stats are reset after ROM flash and your new OS needs time to learn how your battery drains before it can give you accurate readings.
If you can't wait for that long, you need follow the battery calibration thread to force a manual calibration of the battery.
I'll give it a week and see how it is then. Definitely is draining much quicker now though. I think It acted similiarly when I first got the phone as well. If I recall correctly the batter life sucked when I first got it, but then a week or so seemed to get much better.
I did the manual battery recalibration (let it die, charge while off, turn on and bump charge...etc). Last night I lost about 2.5% of battery per hour while in standby. This seems improved since calibration but its still pretty terrible IMHO. Is this in line with the amount of drain other are getting or am I draining more than usual?

Running stock since purchasing the Captivate back in August, and so far battery life actually seems to be routinely as good if not better than 2.1. I must admit I didn't use my phone a huge amount yesterday (except for about an hour plus of downloading a bunch of wallpapers off Zedge for some ungodly reason lol), and after 18 hours of the phone being on I was still over 50% battery life left. 2.5% in standby doesn't sound like all is well - you must have something running in the background or similar issue. I have a live background, sync 5 e-mail accounts (granted, only one of those is every 15 minutes - the others are every thirty minutes, every hour, and once a day on two of them), and with light use I am getting over 40 hours with 2.2 so far (about in line with 2.1, but seems maybe just a little better). Heavy use I am dropping more like to the 12 - 18 hour mark (heavy use for me means the screen on more than off, actively playing games or using apps, large amounts of texting, etc. Solid game playing I haven't figured out a drain yet, but on some games it seems like I can drop almost the whole battery in close to 10 hours). At your rate of 2.5% per hour in standby you would only make it forty hours without even using the phone. I have been using mine just a little this morning (FB check, logging in to one of the desktops at work remotely to make some changes, live background running, WiFi sleep policy is set to when screen is off, but to be honest that is about it) and I haven't moved off the 100% mark yet and the phone has been unplugged over an hour and a half.
All that said though, as other users have stated you might want to give it a little more time for the system to recalibrate the battery usage. I would definitely check your processor usage though regularly to see if anything seems 'off'. One thing that caused me problems was that my SNS service would be running but then would get stuck in a pattern of 'Restarting' - would drain my battery rapidly.
It has been said that bettery drain is not linear. First 5% goes real fast. So, you need to judget the average over a day of use, not first hour or so. I'm still in first week of ROM flashing. So I can't confirm anything yet.

Very curious quirk On Android Open Kang Project ROM... Near Unlimited Battery!!!!

hi all...
soo after my comments over a week ago on the aokp website for this build, i decided afterall to take the plunge and update. i was on b26, so subsequently had to flash b27 and then this. everything has gone absolutely swimmingly with no issues at all so far....
HOWEVER>>>>>
I am faced with a very puzzling quirk. its by nooooo means a problem at all, infact it quite the opposite!!! let me explain.
i've started charging my phone in the evening these days for some stupid reason and then, when charged taking it off and going to bed. After getting this milestone on, my battery has been killed over night, draining to around 15%. Normally, it would drain to around 70% and be flat by the end of the day ready for charging again.
This continued for a few days when i decided to root out the cause of the massive overnite idle drain. I installed a fantastic free app called Badass Battery Monitor (which i highly recommend btw!), and over a period of a couple of days the offending app was weeded out. It was Nova Launcher. This had never happened to me before and couldn't understand it. So, as part of my diagnostics, I decided to confirm the findings by removing it and just using stock.
Over a couple of days monitoring, with exactly the same charging method, my battery levels returned to normal drainage with around 75% battery left by the morning. Fantastic. I had found the problem fixed it and got back to normal. Soooo where is the quirk i here you say!!!? lol Well......
On average, from everything i've read in forums, battery drain overnight while phone in standby is around 20/30%, so mine WAS right up there with the majority of you.
Last night, i decided to charge to full and then wipe battery stats. Which i did. Now, bare in mind here that I ONLY have the standard battery that is supplied with the Galaxy Nexus. I got up this morning, and to my utter amazement, my battery had only drained 2%
Now been incredibly realisting here based on average overnight drains, i was 100% sure that this was deffo an error. I have done everything from restarting the phone, taking the battery out, but still the level in my battery was saying the same.
As I sit here writing this, I have been streaming a radio station via wifi on the phone for the last 2 hrs, and atm my battery is telling me that it is STILL 85% full.
I am DEFFO not complaining, but i'm sure now, you can see why the hell i am so puzzled! HOW THE HELL IS THIS HAPPENING, because i can genuinely find no explanation at all for it
as a follow up, it is now more or less 5 hrs since my orginal post, and my battery is reporting that it is 75% full
Jeesh, 20 to 30 idle drain overnight? My phone drains about 3 to 5 overnight which is typically 8 hours of sleep.

Interesting quirk. Are you a heavy or a light user? It'd be nice to see how it drains after a full drain and recharge.

well, to see if what was been reported was correct, i've been an absolute heavy user today. i have wifi on, ive streamed radio via internet for around 3 hrs, ive been playing all sorts of games and watched a few youtube vids. and my battery is atm reporting 74% life left
so here i am, STILL very very puzzled..
my battery life is just going and going with no signs of running flat... have a look at these screenshots and give me an explanation as to why i suddenly have a super battery!
MAYBE you really have a super battery or your mobile is glitched and shows the battery like that due to laG?
I'm on miui and I lose 0% overnight. It just depends on the ROM, but 20-30% is ridiculous!

Your states do not seem super impressive. On most phones the screen is the biggest drain. You show 49% battery with a screen on of only 1 hour. After 33 hours you've only used your phone for 1 hour screen on. Thats VERY little.
I usually get 2.5-3 hours of screen on time for my galaxy nexus.

Thanks for the app recommendation! Been looking for something like it all day.
This will depend on ROM/Radio/Kernel user installed programs/sync etc but 2-6% is normal drain over night anyone with 20% needs to seriously look @ battery stats and work out what's causing wake locks.
Also not forgetting most phones need to bed in after a flash which can take 2-3 days before we see real battery info.

Bad Battery life or Bad Battery on Nexus 5 with 5.1

Hello,
I've searching for like 2 months about problems with battery life and Lollipop with nexus 5. I understand the issues but since it was released, i never had much problems with it. I used to have 2h SOT for like 40% battery or so.
My daily routine allowed me to reach home with a bit more than 50% battery with 2h SOT more or less. (a lot of messaging on viber/whatsapp)
But something changed since 1 and half months ago. I can no longer do the same and it seems that i have a CONSTANT battery drain. I remember when i unplugged my phone i would reach my workplace (1:30h after unplug) i would have like 2-4% less battery depending on the usage. Currently when i get out of home the battery is already at like 92% or more depending on the usage. If i let the phone stay idle all the time, i usally get home with 30-40% battery now. I'm already thinking that my battery has gone bad. This started to happen from one day to another and i never let the battery stay too much below 30% usually, but nowadays it's impossible to predict the battery life since some days it seems to drain more than others.
I've used some apps to monitor the usage but i really don't understand much about it and can't seem to find a pattern. I've already did factory reset with all Lollipop versions and i remember doing a KK regression for some hours but the drain seemed like it was still there (can't use KK on my nexus 5 anyway, it feels weird after Lollipop experience ) but i didn't even fully charged the battery as i remember. Anyway if it would be an app, there should be some kind of logging in battery stats which doesn't, and i can't think about anything else.
I finally gave up and decided to ask help here, since i don't know what else to do. I'm actually leaning towards getting a nexus 6 but after reading about so many issues (screen/battery life/burn-in) i'm not sure what else i can do with my nexus 5.
If anyone can give me a hint i'd be very grateful
PS: already tried Cataclysm ROM and using currently ElementalX kernel. I notice a bit better battery life with ElementalX but i think the pictures speak for themselves.
Judging by that constant drain with very little shown awake time I'd install Better Battery Stats and check for kernel wakelocks. I had a similar situation with a wake lock from using a wireless charger that did not show in the regular battery stats.

i already installed it before, but currently don't have it installed. I have Wakelock Detector app i can post a screenshot if helps
Installed Better Battery Stats, i'll post results tomorrow (battery at 19% already).
As promised, there's still some battery left but i didn't even use the phone today mostly... in days like these i should be over 70% as usual or maybe close to 80% that i remember.
Can't seem to find the cause
bump i guess
will some full discharge cycles fix this ? iirc that can make things worse.
I feel your pain...when I was on Kitkat, I'd get to work running just Waze and Pandora and my battery life would be at 80%. Installed Lollipop 5.1 and now half way through my trip (15 minutes of use) the phone shuts down with a dead battery. Maybe it's just a coincidence that my battery decided to give up the ghost at the same time I install 5.1, but I find that very odd...the phone is only a 1.5 years old...lithium battery's tend to last 2+ years and even then they don't fall off a cliff in terms of capacity. At this point I think I'll buy a new battery and see what happens, LG OEM are about $25 on Amazon.

Battery Thread

Please post your battery stats here, including Screen On Time.
Thanks.
5 hours SOT and Still at %30
Android System and OS together are eating nearly 50% of my battery.
Same here. System and OS eating my battery.
20 hours with 4 hours SOT. I'm not complaining. Much better than the s6!
First charge with massive wakelock issues...
Completely impressed with battery life. Pretty solid so far.
Not sure how everyone is getting all these legit battery stats. I'm only getting about 4-4.5 hours screen on time.
I'm at 15% with 3 hour 45 minutes screen on. No so impressive. I charged my phone before I went to bed and lost 16% with it just sitting, while I sleep. So much for doze.
Having the same issues. Trying to figure out what I'm doing wrong that everyone else is getting so much better results.
Anyone else care to comment? I'm getting pretty mediocre battery life. I expected ALOT BETTER. I'm averaging 4 hours screen on time. Android system is eating 37% right now.

Same boat here, relatively poor battery life and close to 2%/hr drain when not in use. Slightly better than my S5 active, but not much.

Got the phone 2 days ago, it's a bit early but I'm not getting crazy battery life: I listen to music a lot (5-6h/a day - Deezer or Poweramp) and get 5-6%/hour drain, a bit less (maybe 2%) while idle. Coming from a Nexus 6P this isn't great...

Anyone else have heat issues, my phone got crazy hot and I was just using fliboard no gaming or video watching.
Give it a week or so before complaining
Mine took 5 days to settle
Afterwards a constant 6.5 hr sot sometimes 8
anybody having battery issues,cycle the battery completely and it should improve. when i got my S7 and My S6 also battery was garbage. I did 2 full cycles and man im getting crazy battery after..
anyone not knowing exactly what I mean by cycle heres what I did
use the phone til it dies completely DO NOT TURN BACK ON
plug and charge til its fully charged turn back on use it again til it dies
and AGAIN DO NOT TURN IT ON just plug and charge fully before turning back on.
that was 2 full cycles did wonders for me hope it does that same for ya'll having bad battery good luck:good:
I've done two cycles. I average about 23 to 24 hours between charges. With 3 and a half hours screen time.

Note 10+ battery drain

I've had this phone for two weeks now and the past few days every time I charge it to 100 it instantly drops to 99 after 2-3min of use. I'm not running any heavy programs either if I just have the screen on it will drop. In the screenshot below I had 13min of use and it went down to 98. Is this happening to anyone else? I don't have power saver mode on.

Well, if the phone is 100.0000000, the instant you turn it on it is less than that, correct?

It shouldn't drop 2 percent in 13min should it if the screen is just on?

Seems to be just about right
If you're not getting good enough screen on time and did factory resets already, try reflashing the system. It worked for me.
Mine does the same exact thing. My note 9 never had this issue and I'm only seeing 3 to 3 1/2 hours on screen time..
My samsung SM-N975U battery averages 1d 0h 0m (19h 50m 0s active usage) on a single charge.
My note 10+ goes from 100 to 97 in about 5 minutes. Current situation -
upload
The last thing I'll complain about is going from 100% to 97% in 5 minutes with this type of battery life.
I am in a situation where it feels like its draining faster then it should, but Im also using it more than I should, so I dont know if a phone issue or a me issue. Im gonna do a reset to see if the results remind.
I realized that the Secret for obtaining high amounts of battery life (screen in time) is if you consistently use the phone.I found that I can easily get 10 hours if I'm constantly using the phone to the point where the screen is on for 10 hours. The second I put the phone to sleep and I don't use it as much is when I start heading 6 to 8 hours of screen on time. It's weird how they've implemented this but,
I now just use my device without even concerning myself with the battery life for screen on time because it doesn't really matter. In the back of my mind I know I could get 10 hours if I actually spent that amount of time on my device with the screen on. When it comes to regular usage 6-8 hours on a device that lasts a day and a half sometimes almost 2 days I don't think it's anything to complain about
The problem is that your phone like mine must have came with 4300 or less mAh ... Most likely less ... Mine has 4280 mAh I am very pissed at Samsung for that since my hauwei p30 pro phone have almost 4800 mAh so it spends 8 hours in 100 percent until it starts to decrease the battery that is why so many fear hauwei I guess it was my first phone from then and it's amazing how it is superior to anything I have ever seen before ...
Ya me too how solve battery drain issues
I have a issue with regards to the battery where if the battery is reaches 10% , then from 10 to 0% drains within 1min. Any idea how to fix this or issue with the battery?
