Q: macOS Sierra absurde battery drain
So, here is the thing. I bought my MacBook Pro in 2013 and since then I've never made a factory reset, so I directly installed all the new OS', same thing I did last week with Sierra. Downloaded, installed and everything was fine.
A couple of days ago I decided to do my very first factory reset with Sierra already on my Mac. All went well, Utility, Erase and that stuff was all smooth. The problem occurred when I finally started using my clean Mac.
Now it is always hot, unusually hot even when I'm just browsing on Safari or writing on Office. Previously, my battery life (El Capitan and Sierra before reset) was about 10 hrs, now, only 3 hrs on average.
The point here is, there are many people complaining about the Sierra battery drain and overheating but I have found no solution, is there something I have to do in order to make it act normally (temperature and battery life), or, I just have to wait for an update by Apple?
Things I've done: Spotlight has finished indexing and nothing changed, not using the Photo app, SMC reset did not solve, going into Safe Mode and back did not help.

After a full charge and some rest for my Mac the battery is back with its 10 hrs, so, the 'secd' process discovered in the CPU panel of the Activity Monitor is causing both Battery drain and overheating in Sierra.
Activate the iCloud Keychain in Settings > iCloud and select Keychain, set it up and your Mac should be back to normal.
