I set my wifi sleep policy to sleep when display is off. However, when I look at activity monitor graph in the battery menu, I see that wifi is being shown as still on. I also notice when I turn on my phone I see the wifi indicator. I cant imagine its connecting that quickly!
So my question...is wifi really being turned off according to the sleep policy setting?
How long are you waiting after you turn the screen off to turn it back on to check? It definitely waits some time before shutting the wifi off.

Also if you have anything on your phone that wakes the wifi, or if you are checking multiple times each hour, every time it wakes it will go all the way through search for signal and make a connection and then set idle for a few minutes before it will go back to sleep.
For me I have found just leaving the wifi on all the time was a much lower battery drain than letting it sleep at all.

I like keeping my wifi on while my screen is asleep so that I can receive chat messages or e-mails without being at my computer. I never had this problem while running ICS on an unrooted TF201, but ever since I installed the upgrade to JB my wifi will always disconnect after the screen has been asleep for a few minutes. I've checked every setting I can think of. In the Wifi Advanced menu, I have it set so Wifi is always on, and in the ASUS customized setting I have Disconnect network during sleep to off. Under Power Saver I have Enable low battery settings off, set Low battery level to 0%, and even set Wifi OFF to off. Despite all of this, it seems like the tablet under JB goes into some sort of deep sleep and disconnects the wifi after about 5 minutes of inactivity.
I have noticed that this problem does not occur when the screen is on. I also have the dock, and set the screen to always on during meetings in the event that I don't need to enter any notes for a few minutes so I don't have to fool with any delays from screen wake .
Is there some setting I'm missing? Is it a hidden setting that I could access by rooting? Or am I dealing with something internal to the build that I can't change at all? This may not seem like a huge deal to most, but it has become one of my main uses for the tablet when I'm at home. I'm very disappointed with JB so far even though the wifi does feel more responsive on the Prime after the update (when it's not sleeping, of course!).
EDIT: I noticed this evening that the wifi turns off even when I'm running something that uses it while the screen is off. I was listening to Pandora, and about 5 minutes after the screen went off, my music stopped. When I turned the screen back on, I saw that the wifi had indeed become disconnected.
hey,
I have exactly the same problem with my tablet. I have checked every option, I did a factory reset several time, I have checked it on 2 different routers but it is still disconnecting the wife when it goes in the sleep modus. Did you or anyone else find a solution?
Eh, what kind of battery life is everyone getting.. I Fully charged mine today, made a few test calls but didn't' talk, after about 3 hrs it needed recharging.. Bluetooth is off, Wifi is on, and 3g data is on...
On 1900 USA StraightTalk
There are tons of factors that will affect battery life. Thing like;
Signal quality (as a former repair tech, I've seen poor single kill a battery in a matter of hours on multiple phones +200hr standby phones)
Apps running in the background (Skype + Facebook kills my wife's 10day standby phone in less than 12hrs),
Apps syncing (Gmail and other apps are set by default to constantly sync)
Shake Screen On apps force phones to never sleep and on the TS it runs at 1GHz with both cores at all times with any screen on apps I've tried.
On my bench tests I get about 20hrs of standby with cellular on with G+, GMail, Hangouts, Drive, Calender, Keep, Now, Picasa, Google Voice left alone to sync as they please. This also includes a baby activity tracker that syncs over 4000 entries every hour.
EDIT
Reread and noticed you had WiFi AND cellular on. If wifi is on but not connected to a network it constantly scans for networks which kills a battery. The same goes for cellular.
I turned off WiFi seems to be lasting

The EnSec Patch helps reduce the wifi battery drain issue by scanning every 300 seconds vs every 15. The patch or properly rooting your device is strongly suggested anyways.
Hello experts,
I've been using my trusted S II for several years, when only half a year ago I rooted it and installed NeatROM on it (jellybean). Even before the rooting, probably after upgrading to the official jellybean, I was experiencing the following scenario:
I put the phone on airplane mode when I fly, or simply turn off both Wifi and Data (over 3g cellular network), so to reduce the battery consumption when I go to bed and don't want to be woken up by texts at 3am. I also turn off Sync option so that different apps (like gmail or calendar) won't wake up the device and try to connect to the internet every minute (and fail).
Then after a long period I turn on Data or wifi, and then - BOOM - a massive drain of the battery, which is accompanied by sluggishness in responses to me pressing the screen or even pulling down the status bar. It is as if all the apps that need an internet uplink - Facebook, Messenger, Whatsapp - wake up at once and try to get online together.
Does anyone else experiences this kind of effect? Is there a way to fix that?
Thanks in advance.
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Google Pixel 4's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

Really good standby drain for me. Around 0.7-1. %
The standby.. Everytime is different.
Sometimes i get 10% overnight. Sometimes 6%. Sometimes 7-8%. And last night 2% (for 7h).
Wifi always on, motion sense on, AOD off, adaptive battery on, phone flat on display

turn off adaptive battery and your standby time will be closer to the post before you

Tried one night. It was about 8% for 8h..
And last night it drained 5% in 9h, with adaptive battery on

this is with 60hz.. check to see if wifi scanning is on. even if you turn it off and you use an app that asks you to turn location on like Google maps. if you hit yes it will automatically turn wifi scanning back on. I also turn off auto sync and sync things manually when I choose too.
Thanks for the reply.
How is going in prolonged standby? I've observed that when commuting it drains more battery. Even if i am using location history that's a bit too much, because most of the time i am not moving. I am just placing the phone on my desk.

Turning the wifi and Bluetooth scanning off are among the first things I do when i setup a device.
I need auto sync.
I've just turned off "mobile data always on" from developer options and will see if it helps or not.

having location history on shouldn't affect the battery, it's just storing history.
it'll turn back on though if an app requests for location and you press yes. for ex. use Google maps and it'll probably ask for location to be turned on even if you have location on already. if you press yes it'll turn on wifi scanning.
I do the same. turning off mobile data always on should help.
the standby drain usually comes from play services, but it could also be an app that was downloaded. from my experience, it's usually play services.. yeah if you need autosync then it is what it is. because even if your phone is face down it's still going to use your cpu. it's probably better for you to turn adaptive battery on, but you should limit/restrict your apps manually, instead of letting it notify you when it thinks an app is running too much in the background. I know a pixel 3 user that was using adaptive battery with 30 apps restricted and it was working for him. I never restricted apps manually when I had adaptive battery on. that could be the reason adaptive battery never worked for me. my play services would be higher than 5%, sometimes even 15%-20% with it on. now I rarely go over 4%
these pics are from my 3. it also depends on your reception, there aren't any battery saving tips for that , except to put it in airplane mode.
one more thing is to calibrate your battery. I understand that li-ion batteries don't have memory like nickel. but I think it something to do with the OS storing the battery capacity or something.
charge your phone to 100, drain it till it turns off. plug it in and charge it to 100. unplug turn it on and repeat the steps 1 more time. this helps especially on big updates.
the battery becomes more efficient and consistent. when I updated to 10 from pie my battery would drain quickly to like 50% and then below that it would slow down.
I am roaming right now and connected to a WiFi network with dual band on the same SSID. It's frustrating how much the battery drains when idling!
7% loss in less than 2h completely idle..
From 95% to 88% in 1h40 of standby!
I have no access to the router to force it on a band, it keeps switching from 2.4ghz to 5ghz.
If i turn off wifi and leave mobile data on, then Google Play services is on top of the draining list.
I am starting to hate all these Android inconsistencies..

turn off your auto sync. it updates every 15 mind and keeps your phone from dozing. just manually sync it. it literally takes 6 clicks.

Man, it has literally nothing to do with auto sync.
I have battery issues both when using the phone and while standby.
The phone is getting annoying warm. That doesn't happen when i am home. Now i am using a different wifi connection.
Now home (different router, different SSID for each band) the wifi consumption seems normal and the phone doesn't heat anymore while using. That's so pity when you have no control to wireless router and you get into this situation! This seems to be related to Android, since i had the drain also on OnePlus 5.
Made a little test, when not in "doze mode" it consumes 2% each hour.
And overnight somewhere between 4-8% (random !?) for ~8h.
All standby times, no background tasks
Wifi & Bluetooth scanning off, motion sense off, idle screen (AOD) off, wifi on, location on, always on data off, Bluetooth on, tap to wake on, lift to wake on, now playing on, assistant voice match off
My battery drain reduced to 3% overnight (8+ hours sleep), with motion sense completely OFF
@jalado do you have any issue with Google play services or phone idle consuming a lot of battery?
I've attached a screenshot with battery usages.
I've already cleared Google play services data + cache yesterday (+ a reboot after about 30mins) before charging.

no, my idle drain at night is like 1-2% over 6-8 hours. I don't have auto sync on though, so my phone stays asleep. your play services seems good for auto sync being on. mine's around 3% a day, if that.
I will try to turn off auto sync overnight and see then.
I got 6% drain for ~8h overnight.
Btw, when home with wifi on i have no issues with Google play services battery drain. But when commuting and with data usage (being on mobile data about 2h of the time) the drain is high!
I have to test more and see if it's because location history, Google fit or mobile data. Or all..
So I've turned off auto sync overnight.
It drained 6% (70% -> 64%)... So for me the same drain :/.
Another thing that i am disappointed of is the Google Play Services when on mobile data (on idle/standby). I am on LTE with good coverage.
