Wifi Shuts Off/Throttled While Screen Off - Samsung Galaxy Nexus

As the title says does anyone else have this issue with their GNex...I have the HSPA+ version on AOKP Build 21 with Franco Kernel 14.4 but whenever i have wifi connected and the screen shuts off...the connection gets super slow/shuts off even tho it still says on the phone its connected...Also i have the wifi sleep policy set to always on...but it still exhibits this behavior...only fix for it is to turn the screen on and then it ramps back up to normal speeds/useable...Case in point using Airdroid/Wifi Explorer Pro to transfer files...if you leave the screen on the transfer completes as it should however turn the screen off and watch the transfer slow to a crawl/fail..not sure if roms/kernels affect this but its rather annoying having to keep the screen on for this..im not sure if i'm the only one with this problem...if not lets find a fix.

Do you have power saver enabled in rom control?

I am having the same problem using AOKP w/ lean kernel. I am not using power saver and have my wifi set to always stay on and my speeds still slow way down. I have also used set cpu to keep my clock speeds high when the screen is off and get the same results. A fix would be nice!

How can I tell what's keeping my phone awake?

As you can see, something is keeping my phone awake while I'm not using it

How can I find out what it is?
Could that just be phone idle?
But why would it be awake so much when i'm not using it?

Click to expand...
Click to collapse
Try CPU Spy. That's what I use to show what percent of time the phone was in Deep Sleep for. It doesn't tell you what apps have caused you to wake from Deep Sleep, but should give you better figures
You seem to have poor reception. Maybe its the phone switching from 2G to 3G or switching towers?
I had wake issues on firmware 2.3.3 where the phone would be awake for up to 90% of the time, 2.3.4 seems to have fixed it.
could be apps syncing data in the background?
empty the dalvik cache folder and restart your phone......let the phone setup the cache for each app again .
i was having very bad battery life .. its like just 2hrs off gaming and 5 hrs normal use plus
my message tone use to rang and notification bars shows nothing ... noww ALL is WEll "D

[Q] Massive cell standby battery drain when on WiFi Calling

Has anyone noticed this on their Edge? I'm running the latest software release including the OTA. On my previous phone the GS4, I never had the same issue with WiFi calling and this type of drain in the same location.
So far, I've tried turning off VoLTE, but I'll need a few days to see if it makes a difference. Any one else have other suggestions?

There is a discussion going here about this:
http://forum.xda-developers.com/galaxy-s6-edge/general/galaxy-s6-edge-battery-life-t3068598
Some are saying turning off wifi fixes it. I'm testing it now
Turning off WiFI fixes the issue. This is what you should do: Turn off wifi, fully charge phone, restart.
Thanks, I'll give that a try. It should be a permanent fix correct? Hopefully there's a software update soon.
Ok...So here are my current stats. I had Wi-Fi off the whole time. About twenty minute phone call, web browsing, about 1.5 hours of audio streaming with screen off.
I am okay with this and think it will just get better as the phone settles in.
Lost about 8-9% overnight while sleeping.

Wifi Problem - SG Ace 2x (GT-S7560M)

Hello everyone,
I'm in desperate need of some help here.
My wifi suddenly stopped working and im not quite sure how to describe it so ill post a photo.

}
But when the wifi does successfully turn on, it cant find any networks, it just keeps on scanning.
Please help.
Some additional information
Rom: Stock SG Ace 2x (GT-S7560M)
Phone is rooted.
I've tried everything I know that might have fixed the problem...this means factory reset (data/cache wipe), reflashing the stock rom and turning the phone off and removing the battery for a few minutes.
Update: This morning, I turned the phone off and took the battery out and left it like that for around 14 hours and when I put the battery back in the wifi was able to see networks and connect for approx 15 seconds, then it turned off again. Halp please..
I noticed that removing the battery for prolonged period of time would return the wifi to a functional state for at least 1 minute before all the networks disappear and it cant connect to the wifi again.. what do you think this means??

Wifi drain on Marshmallow

Hey guys. I have a M5 dual, Android 6.0, unlocked BT and rooted. Since I updated to 6.0, my battery stands for less than one day. It used to last at least 2 full days.
Looking at the battery usage, Wifi seems to be the problem. However, I'm not using wifi at all. For testing purposes, I disabled wifi, wifi scanning, and location is set to device only mode, but it still reports that Wifi is eating more battery than anything else.
The only way to stop wifi from appearing in the list is setting the device to airplane mode. Does anyone know what it could be?

Ive disabled adaptive brightness and wifi scan and now the battery life is better.... But not even close to 2 days life
I kept looking for a solution and I found one that worked at least for me. It's worth a try if you're having the same issue with WiFi being what drains the most battery life.
Settings, backup & reset, Network settings reset.
This will wipe all your network data, including your stored WiFi passwords. If you had to download any configuration data from your carrier to make your 3g/4g work, you'll have to download it again.
