Standby drain

[JasonJoel]

If the drain is coming from system services, you likely have the play services bug that has been talked about many times. search for it.

The o my fix until Google fixes the services directly is to turn off WiFi, REBOOT THE PHONE, and leave WiFi off.

I capitalized reboot on purpose, as just turning off WiFi once it is on will not stop the battery drain - you have to reboot.

I'm getting about 7% drain overnight with battery saver on, flight mode on, location off

Very disappointing Standby battery drain

Despite all my optimizations to make sure there's nothing (no syncs, or any other apps) running background services, with the Battery Saver mode and Data Saver modes on and the phone on Airplane mode, no ambient display, no FB. most apps manually stopped from System->Apps to make sure nothing is running in the background. Despite all this, 5 hours of idle time over night cost 6-7% of battery usage on the Pixel 2 with all of that going to "Phone Idle".

Under identical conditions or even fewer optimizations, the Pixel 1 only uses 2% and just about all the other devices I tested (LG G6, GS7, Moto G5Plus, Sony Xperia XZ) using about <.5 - 1.5%. The Sony Xperia incidentally seems to be consistently best in class with near less than .5% usage over an even longer period. All iPhones I've tested and used before do well in this department as well with no more than 1% used in the same time period.
This is VERY disappointing! Why would the Pixel 2 have a significantly worse idle battery life than the original Pixel? You would think by 2017 Google could do better here.

Could be something you have installed isn't playing nice. I forgot my phone off the charging the other night and after 8 hours it only went down 3%. I don't have very much stuff installed to begin with.

@Electroexpert seems you felt into a very small group of pixel 2 users with the same problem. I did the same optimizations and I get 1-2% battery drain over the night (6 to 8 hours).
What are your average Screen on time results?

 

[Electroexpert]

Thank you everyone for your posts. To be clear, I was okay with the overall battery life of the Pixel 2 and never complained about the SOT battery life but strictly the Idle/Standby time which was definitely the worst in class compared with all the other phones I had listed. I made another round of optimizations (disabling all VR and AR apps and services and also turning off the "Find my Phone" service). FINALLY, I have the overnight consumption down to just 2-3%. I feel like disabling the "Find my Phone" feature made the biggest difference.

For another data point, last night, my standby battery drain was 6% (100% start) over 12 hours. I'm not sure how that compares with other phones...definitely better than the 3-year old HTC One M8 it replaced. Still...always interested in better battery life and performance, so I'm all ears for tips and tricks. Also, if it matters, our house seems to be just out of good cell phone range. We are only getting 2 bars on Verizon. Per above, even on standby, that might contribute...although I also have my phone on Wi-Fi.

That's terrible, something is wrong. I only get 6% drain overnight with all radios active (wifi, bt, NFC, cellular) and no power saving mode enabled.

Yes, cell signal strength will make a difference. Even with WiFi on, the phone tries to stay in contact with the cell towers for calls/sms

I get between 0.5 to 0.8%/hr and this seems typical for this phone. WiFi and Cell on, other radios off. I consider it not bad considering my last phone had a 3630mA/hr battery (Moto X Play) and would lose a similar % on standby.

I got 3% battery drain on standby over 12 hours using force doze rooted, but you don't need root if you give it permissions via adb. I highly recommend it.

Any guidance on how to do this pal?

These are the permissions forcedoze needs. the instructions are also in the description on the google play store.

"adb -d shell pm grant com.suyashsrijan.forcedoze android.permission.DUMP"

"adb -d shell pm grant com.suyashsrijan.forcedoze android.permission.WRITE_SECURE_SETTINGS"

Mine drained from 44% to 29% over the night. Had Gmail, Twitter, Pushover and Whatsapp notifications. Everything enabled, adaptive brightness turned off due to the unstable nature.

I think it's quite normal. Mine goes about 10-15% within 8 hours. I have over 100 apps, above included.

 

[Stretlow]

Ok I've been losing 10% overnight (8ish hours) on wifi which is crap.

I've narrowed it down to the following
* Location Settings
* NFC
* Now Playing
* Ambient display and subsequent settings

With all these off (location on device only) the battery is only dropping 4% over the same period which while is still not as good as I've had in the past (2%) i'll probably settle with.

Going to test each one on individually over the next few nights to find the culprit..

 

[jericho246]

AccuBattery says I only lost 7% (174 mAh) in 16h 23 minutes. I'd say that's pretty good!

 

[Daandofreak]

After trying several settings against bad over night drain (4 to 8%) i am switching off my phone at night.

I had a huge batterydrain from the built-in Messenger (sms/mms).

Swapped it out for aosp sms just to see if the drain would stop and yeah, it made a huge difference for me. So try that if you havent already ?

Edit: dont forget to disable android Messenger or the batterydrain will continue.

 

[davidisflash]

Facebook and facebook messenger are my only drain culprits, mainly when using my phone. They also lock up the phone intermittently. Same issues with the apps when I used a Galaxy S8. Overnight with ForceDoze and leaving Bluetooth and wifi on, I'm probably losing like 2-3% over 8 hours. Not bad.

 

[bspcsquad]

Not satisfactory. About 1%/hr under either home WiFi or 4G, but it's mildly surprising that even under Airplane Mode it drains ~0.5%/hr. Moreover, I cannot use my office WiFi because my Pixel 2 is losing >5% per hour when connected to it (maybe due to the lots of computers in the same network, but other phone models do not have the same issue)

EDIT: tried Safe Mode and the results are largely the same.
