WiFi battery drainage - Nexus 4 Q&A, Help & Troubleshooting

I've got a problem with WiFi consuming too much battery. I fully charged my phone and did not touch it while it was connected to WiFi. After 2.5 hours, it was at 88% saying most of it was consumed by WIFi and standby mode.
I have "WLAN optimization" turned on. I never had this kind of problem before with other phones - does anybody have an idea what I could do to reduce the battery usage?

maybe you have apps synchronizing and draining the battery, try greenify app to hibernate what you dont need when phone is on standby mode.

Sleep/Standby Battery Drain

I have seen many posts about the poor battery life on the ADAM when in heavy/normal use. I have seen very bad battery drain just in standby/sleep on all the roms I have tested (Stock Newest build, edenx, and now CM7). SetCpu currently doesn't support profiles but I wonder if the processor still runs heavily even when in standby.
I should note that i usually turn off WIFI when not in use and also background data sync.
Pixel Qi Wifi.
As usual, after unplugging the device in the morning and not touching it for 8+ hours, it has about 50% battery left and battery history shows Phone Standby using all the battery. I guess these quirks will not be resolved until Honeycomb if ever.
Which do you mean "cell standby" or "phone idle"? I have the same model and the battery still drains more than expect overnight, but notas much as 50%. Did you apply a fix to remove cell standby?
Phone idle is what is reported. Here is a more specific example: on battery power for 10 hours today in standby with wifi off and background sync off and the battey is down to 55%. This is not a huge problem but I dont like to leave it on the charger constantly when not in use.
Kill the "phone Idle" <- that's really draining and if you don't use SIP on a WiFi only you can de-install phone and phoneprovider
2 other things you could try,
Install from the market:
"autokiller memory optimizer" and
"Juice defender"
They seem to help for me.
or use BEAST ROM 2.2. My ADAM batterie status is after 23 hours on 36%.

Major battery drain during standby

My battery is dying from full within a few hours on standby. Looking at battery usage says 91% is from wifi. Is there a way to determine exactly what from wifi is draining my battery so fast during standby?
I'm using Prime 2.03 and Clemsyn ver 22
Set your wifi to "off" when screen blacks out. Also go to the market and get the Auto Airplane Mode app. This app along with the wifi off option when screen blacks out basically made my battery life incredible!!
Or read this thread http://forum.xda-developers.com/showthread.php?t=1287799
To be honest, my TF is almost always on and in standby, not in airplane mode, with wifi on. With little to no use, I've had it last multiple days before fully discharging.
The only thing I've done, and I recommend everyone do, is turn off "Network Notification: Notify me when an open network is available". From what I understand, if you have that on, your wifi card will continuously poll and try and find an open network. I could see how that might be your issue.

how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.
First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection
Green power
Deep Sleep Battery Saver
All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.

Very high standby drain.

There is a big battery drain on standby even with WiFi, bluetooth, mobile data switched off. Waking up in the morning with over 20% drop.
Seems like there is a lot of wakelocks happening in the background. I've just done the factory reset. Can anyone help me out here ?

Battery drain...

I have removed all the unnecessary crap (ADB). When I charge to 90% in the morning, there is about 30-40% battery left in the evening. And this is when the tablet is not being used.... Is this normal?
Install GSam Battery Monitor and see what's eating up your battery.
Kernel and android...
so, the battery drain problem turned out to be wifi - with wifi off the tablet lasts more than a week without charging, at least in my case.
I use the WiFi Automatic app to turn wifi on and off automatically.
