Situation: * we can test suspend through /root/measure-suspend * on 4.3 kernel it is ~50-58 mA on GTA04 and OpenPandora * on 3.7 kernel (GTA04 only) it comes down to 20 mA we do not know what the difference makes, except a hint from thermographic imaging that some component in the TPS65950 is still getting hot: http://lists.goldelico.com/pipermail/gta04-owner/2015-October/006814. html

Radek tells: There was some alsa fix saving 5mA: http://lists.goldelico.com/pipermail/gta04-owner/2015-November/006819 .html

Disabling musb or the phy-twl4030-usb makes the suspend power go down by 25 mA. So this means the musb code with the USB client is not properly suspending.

Regarding comment #3, I think the following email messages from the Gta04-owner list are interesting: 1.- http://lists.goldelico.com/pipermail/gta04-owner/2015-December/006912 .html 2.- http://lists.goldelico.com/pipermail/gta04-owner/2015-December/006929 .html

I found these email messages to be interesting: 1.- "We have a new mailing list for Letux kernel development:" http://lists.goldelico.com/pipermail/gta04-owner/2016-February/007029 .html 2.- Letux Linux Kernel v4.5-rc4 is available for testing on GTA04 & "it has a significant change to phy-twl4030-usb": http://lists.goldelico.com/pipermail/letux-kernel/2016-February/00004 4.html

current (5.0-rc) known bad boys: bluetooth (+10mA GTA04A5, +70mA GTA04A4) so disable bluetooth (no hci0 should be there) if not needed current record low is around 15mA (w/o modem)

Suspend issues are even increasing. It seems as if the OffMode is broken since v5.6-rc1.
