[Q] Fix wifi active battery drain

[kidbudi]

Wifi is active the whole time my device is draining about a third of my battery. I have wifi pop ups off, always allow scanning off, wifi notifications off, and smart network switch off as well. I have no idea what is causing wifi to drain so much battery but if I could fix it the battery life would be amazing.

Does anyone have any clue how to fix it and or is anyone having similar issues?

No updates yet, desperate for one though.

I mentioned in the original post that I have already done that and it hasn't changed anything.

strange than... I only saw this while this scanning is on.. write Samsung support.. or go into a store..

 

[kidbudi]

Yeah looks like it's going to have to come to that

Trying that now, I'll report back on if it helped or not.

Check if you have multicast enabled on your router. Disabled it on line and all my phones are now showing no wlan wakelocks

I don't think that those stats are correct, what you should do is look at wake time, I get 50% drain from wifi yet the battery hasn't moved and the phone was deep sleeping

I'm trying this now, I have also tried disabling NFC which didn't help.

Its looking like this is a bug with the galaxy s6 edge at least because nothing seems to be helping the issue. I hope we can get a fix otherwise maybe expect it in a OTA update?

Here's mine, although it shows high drain from wifi I get good SOT

This isn't a bug with Touchwiz or Galaxy S6/S6E. It is a known Google Lollipop issue on versions prior to 5.1.

Us Nexus 5 folks have been dealing with this issue until we got 5.1.

So how did you deal with this? Can root fix this?

No. Just have to turn off Wifi when not using it & wait for 5.1.

Ahh I see hopefully we can get that fix soon but I doubt it because I'm on Verizon

I don't have this issue. I'm not rooted or anything. I keep wifi on at home all the time so I can get social media updates and etc. Getting good SOT and no Wifi Drain that can be alarming. [International Version]

Wifi battery drain - only on "enterprise" network, not home wifi

Wifi drain is ONLY on my Enterprise network, no drain on home wifi. The major difference is PEAP vs WPA for security.

Wifi enabled at my work (Cisco infrastructure)
EAP method EAP
The "downlink" arrow is ON continuously, and the battery drains to dead in less than 9 hours. Turn wifi OFF and use 4G (or be on home wifi) and battery is good for nearly 20 hours.

I'd be curious to know if those experiencing the wifi battery drain are noticing anything similar.
Best regards,
