For more info about services to disable see also here and here.

For more info about both services and autostart items to disable see also here.

In Autostarts I've got also disabled most 3rd party apps (except for few like BetterBatteryStats, Greenify)

Note: Instead of Autostarts and Disable Service you may use another similar app that does the same, like System Tuner etc.
