Lenovo Flex2 15: NetworkManager issue with WiFi in Gnome3 & battery

I've installed Arch on a Lenovo Flex2 15 and most of the things are working nicely. However 1 issue with NetworkManager is driving me nuts.

I have the following system in use:

Gnome 3.14.1 overview:
Memory 7.7GiB
Processor Intel Core i3-4010U CPU @ 1.70GHz x 4
Graphics Intel Hasswell Mobile
Base system Arch Linux 64-bit
Disk 329.0GB

[dennisf@hossman ~]$ uname -a
Linux hossman 3.16.4-1-ARCH #1 SMP PREEMPT Mon Oct 6 08:22:27 CEST 2014 x86_64 GNU/Linux

                   -`

 .`                                 `/

Whenever I connect to a wireless network with the network applet in the top right of the screen, it keeps "connecting" even though it has already connected. This does not happen when I disable WiFi and use the cable. The connected cable icon is show properly.

I have disabled netctl
$ sudo systemctl disable netctl

How can I make the applet show that the connection has been succesfully established?

Bonus question is that on Windows the laptop can run for hours, but in Arch it's drained considerably faster. I also have a Dell XPS L502x and since Linux was installed the battery died pretty quickly because it drained so fast and we had to charge it constantly. That laptop is left with a 15 minute charge at 100%. The new Lenovo somehow takes 3 hours to charge from 0 to 100% and drains in about the same time. The same applet in the top right also keeps saying "Estimating...". I have installed PowerTOP and ran a diagnostics. Is it save enough to apply everything suggested?
