WI-FI on Battery Usage Graph - General Questions and Answers

Searched around but didn't seem to find this specific issue in the forums.
My android marshmallow phone sometimes disconnect from wifi when screen is off and come back when screen is on despite the "keep wifi on during sleep" set to “always"
battery optimization is off.

Troubleshooting this issue with battery statistics i found out that during the disconnect period there’s a gap (red arrow on screenshot) then when screen is on and wifi auto-reconnects, the line returns.
I’m having hard time understand how this stat is triggered and having an insight about it.
During this gap is it possible that the wifi supplicant crash somehow with Access Point and then turn the wifi radio off or does it simply represent that wifi radio is disabled by something ?

[Q] Bad mobile network signal causes phone to be awake?

I noticed that my phone is awake more often when the mobile network signal is not green!
I thought this mobile network is handled by the Radio and should not have anything to do with the ROM, but it seems like I am very wrong.
Can see clearly from the graph that the battery drain is very minimal when the network signal is green and plunges when its yellow, the phone is awake more often as well, which might explains why.

Will try with 2G.
Your phone may be waking because it is trying to obtain a better quality signal. Also if you were driving on a highway, the radio will drain more battery because it will be disconnecting and connecting to new radio towers very often.

Maybe you should do a factory reset after the Lollipop-Update.
When does your WiFi turn off? When your screen is off? Do you have a weak signal? Or a powersaving app/mode?
It luses signal every few moments and reconect. It does it even when I wach YouTube video. Signal streinght is max becouse I am sitting 2 meters away from ruter. I just tried factory reset and wiping cash but I still have same problem.
Ok. I fix it witn your advice. Tnx a lot.

Wifi issues

Hi all,
I've got two wifi networks set up at home. One in my room and one in the kitchen. But everytime I get home and turn on the wifi on my phone while I'm in my room, it automatically connects to the kitchen wifi and vice versa. I've tried turning on the option to avoid networks with low signals, but then it just stays disconnected instead of connecting to the network with the stronger signal. Does anyone know how to solve this problem?
TIA
Hi there,
This phone apparently has the WORST wifi of all smart phones for the past 2.5 years. Read review below:

Can't find the Wi-Fi notifications setting

Hello! Recently (probably after the latest update) I've been getting Wi-Fi notifications whenever I turn on Wi-Fi in an area with no saved hotspots. I know that in order to turn it off there's a setting in Connections > Wi-Fi > Advanced > Network Settings as per this image:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
However, that setting is nowhere to be found for me. I can't find it with the search function, and the Wi-Fi settings looks like this:
Does anyone know what happened to the notification setting? I am certain it used to be here, since I've disabled it before. I also use a European G955F model, if that's relevant.
Thanks!

High overnight battery drain

Losing more than 15% overnight despite having WiFI, BT, AOD turned off. It's been happening since first week of December. I ignored it at first as it wasn't that frequent and most of the time I didn't lose more than 5% overnight but these days it's just frequent although I tried factory reset, restricting apps and more but still half of the time I do lose lot of juice overnight.
I've attached screenshots of Better Battery Stats, help me figure out what's wrong ?

The "android" waking up your phone all the time seems like an obvious culprit, but that's probably just "anything that's part of the system"... Can you get more detail on that?
