After installing the Marshmallow update on my Moto G 2015, like many others I started to see increased battery drain from WiFi via Battery Usage monitor. I wasnt clear if it was a reporting bug or if it was having an impact on battery performance....nevertheless it was annoying to see it at the top at 18 to 25%.

So I followed some suggestion to access the WiFi settings then Advanced to ensure keep wifi during sleep was set to only when plugged in.

Then accessed Back up & reset settings and reset netork settings. While this means I had to reenter wifi password and bluetooth devices, it fixed the problem.

This is not a fix, you won't be able to receive notifications.

Why wouldn't you receive notifications? All WiFi, Bluetooth, and cellular data settings are returned to default, it should not effect notifications...

Never turn on Wi-Fi while the screen is off for me means that as your phone shuts down the screen it also shuts down Wi-Fi

Assuming you do it in the order stated above, when you reset network settings WiFi During Sleep will change back to Always.

I have never had the "WiFi drain bug" but I have all services on all the time, the code isn't at fault, a setting or a "update bug" is the problem. Resetting the networks settings should correct it.

I skipped a line, my fault.

Reseting does not impact notifications. Only impact was having to reenter my wifi password and pair my bluetooth headset again.

This small inconvenience is worth it. As I no longer see wifi using up the battery (again not sure if it really was doing this but it would be at the top of the list and now its gone).

that didn't work for me, I reverted back to 5.1.1 and all is beautiful again, after 63 hours and 31 minutes of WiFi (always on) it has only used 9% of battery (after 2 days and 15 hours of continuous usage !!!), screen time is beyond 3 hours, I spent more than an hour on the phone with actual voice calls, used WhatsApp and Facebook and the regular stuff... and still have 41% left of battery so it will go a bit longer than 3 days battery time at this rate, after the external storage nightmare that Marshmallow brought to my phone (or Motorola) and the random bugs... why should I even think of "upgrading" when 5.1.1 is running beautifully, I will wait for next update 6.0.2 or whatever, hopefully with no bugs.

I have this bug.

I wiped the cache and the cache partition.
Now I resetted the network settings and I'll see if Wi-Fi will stay on top power consumption.
I can see the battery life is normal, more or less.

By the way I think settings in MM are too nerdy

didn't it get fixed with a factory reset ? ?

[erchiappa]

I don't know if I want to factory reset because it doesn't seem a major bug.
It is annoying for me but I don't get this battery life with lollipop.
I hope in a 6.0.1 or Fw upgrade for the moment.

you have battery drain due to some WiFi issue, go to backup & reset in setting and reset "network settings", reboot phone and tell us whether that solved it or not so we can try other fixes before a factory reset.

I have no battery drain, just abnormal Wi-Fi percentage, but I tried everything
