[Q] WiFi Optimisation - Nexus 5 Q&A, Help & Troubleshooting

I've heard from some places it improves the battery, and other places it has a negative effect. But what is true? Does the WiFi Optimisation actually do anything at all, and if it does, what exactly does it do? Thanks in advance for any answers

Wifi optimization is letting the device fully use the wifi radio at its max speed so if you have a 100mb connection and if that setting is uncheck it would get 100mb fully but if it's check it may use only maybe 34-55mb to conserve the battery used by the wifi radio it's best to leave it on

Insane battery drain

I am on Prometheus ROM with stock kernel. The battery drain is insane and it only happens when Wi-Fi is unable to turn off and gets stuck, any suggestions?

The only thing I have installed that relates to battery saving and wifi is wifi static which forces a static IP
@hugokaka which icon are you looking for specifically?

This can cause your problem. Wifi is trying to connect but can not by strange reason. I have this with different roms an kernels combinations. No cure till now.

Yeah something is very wrong in the new version of maps.
I have the same problem. I am running CM10 so this is not a sense issue. I found force closing maps stops it for a little while.

try turning off GPS and see if that helps any. Do you have location history or location tracking enabled through the settings on maps? Try messing with the settings there.
I just went poking around in maps settings and found location history was enabled. This seems like it was the problem. Thanks for the tip!

My settings were/are all off. No history or reporting (that I authorized anyway)

Please help four hours on 4200mah!!

Its dropped 1% per 2-3minutes. It has to be an app or something but GPS BT WiFi all off screen 50%. I killed apps I'm not using. Wtf? Should get 8-9hour screen time at least 7. Plead help

That to me looks most likely some setting and ROM issue. Make a backup flash another ROM try how it goes but am pretty sure Any other ROM shouldn't drain this much. Don't want to judge any ROM or anything just trying to help.
What battery model is it? Some of the extended batteries going around are just regular cells in a fat case with shims, especially the cheaper ones.

Google+ killing my data

Google+ ate up over a gig of data in the last day. I disabled the app, but you can see in the data usage pic that it used 1.63 (removed app). I rarely ever use G+ and I don't sync anything.
Any ideas why this happened. I got a data all alert yesterday saying 65% was used, and another this am saying 90% had been used which was all G+!!!

Maybe it was auto-uploading photos?
Actually had that on off also. That's the first thing I checked. When I use that feature I have Wi-Fi only since I pay for data

Mobile data always active

Hidden away, in Developer options, is an option to keep mobile data always active. Even when wifi is active, for fast network switching. I assume that we want this enabled? Just curious.

I've had it on for awhile now, on different phones and from I've noticed it's for fast Network switching. Never had an issue with it being on all the time. Orero and earlier had an option for wifi being aggressive in handing over to carrier data when wifi was poor. Don't see it in pie now. I would have that option as well as the option in for mobile data always active
