Battery lasts for only 2-3h if Wifi is enabled. It seems as power-saving is not enabled or broken in mainline linux for libertas_sdio. Paul might have a look at it for our 3.12 Android kernel: http://lists.goldelico.com/pipermail/gta04-owner/2014-July/005823.htm l

Mainline kernel (linux-next) has working power saving during connections. There are still parts to be upstreamed. What needs to be checked: wpa_supplicant configuration in userspace. The settings for the scanning interval should be sane.
