Let's talk about IDLE or more specific STANDBY battery drain.

Have you ever wondere how much your phone is influenced by having Google Play store installed and google Play services doing all that stuff in the background? Mail Service refreshing your Emails whenever they want....

But hey! we got Doze now, right? That stuff keeps the phone at bay over night... but does it?

Using Battery Historian i've made two Benchmarks... in Flightmode... to check out the WiFI Powerdrain. But well, that test Failed, but there are still a lot of other interesting infos in this :)

Made on 1.92.709.1 Stock Rom

Run #1 Completely wiped internal SD, UserData, wipe Cache&Dalvik and rebooted, did NOT setup a Google account, did NOT restore anything, Deactivated Sync. Installed BetterbatteryStats.apk OSscriptmanager.apk and flashed Systemless Supersu.zip

Run #2 Setup Google Play, Gmail, HTC Mail via Hotmail.com activated Sync

Aggregated Checkin Stats:

Very interesting to see here in the Userspace Wakelocks the stuff thats happening on #2 a lot but has a 0 on Run #1

Mainly Google Services and HTC.Mail.... how unexpected ;)

The Sync Manager is also pretty obvious, if sync was deactivated on Run #1

But not only Syncs but also WiFi Wakes due to Email^^

And the Apps Accessing the Internet:

Going to the Kernel Wakeup Reasons we see some strange stuff:

There are way more Unknown Wakups on Run #2 (150 to 98) but yet they don't take as long ( 12.4sec to 19.3sec)

Also we have 7 qpnp_fg_update_temp on Run #2 that did not happen on Run #1... whatever app interfered here.

Now to the interesting section :cowboy: App Wakeup Alarms:

Run #1 does NOT have a google Account setup, and yet the Google_Services do have 22 alarms... That Stuff is just way to deep integrated in Android.

With the Account active and running we have 60 Alarms.

HTC Mail has only 4 Alarms in this 9 hours, so i guess the "Intelligent Sync" function does work pretty well.

i have absolutly no idea why Maps needs 5 Alarms on Run #1 while it doesn't have a single one on Run #2..... but whatever.. it's Google Maps... it does whatever it wants anyway -.-

About Google Photos and Hangouts (talk) I've deactivated the APP in App Settings, i don't really like them and with Playstore i could install Piktures so i don't needgoogle photos anymore.

So.... What's the overal Conclusion?

DOZE? Nice try but try again!

With Android 7 when Doze will worke in a lighter mode even during movement, it might be usefull. But right now for an Overnight Standby it isn't powerfull enough.

You're better off using some app that kills Sync and blocks all wakes like Power Nap or use some other app like Tasker to Deactivate Mobile Data/WiFi and Sync during nighttime.
