It seems that it is using a dual partition system, when rebooting restores the daily partition with the backup. I did not really research how exactly it works but as an example if you delete a system apk file on a rooted android when rebooting the apk is restored.

I used Ninji twrp, and it does ask for a password when trying to mount Data partition, but for System partition no problem mounting, also of course there are other methods, but this one does not require root as twrp has the correct rights to modify System.
What is Baidu_location doing in our machines is unknown to me, first time I was aware of this software was after changing the sim, a message came out asking for permission for the software, but to my understading this software is not needed at all.

Hi, my Cosmo also had too high battery consumption, so I tried to isolate the cause as the statistics of battery consumtion are not available.
  First is of course codi, it takes a lot of battery, turned it off to see the improvements but still too little battery.
  I turned off almost all the software, all planet and google software that you are allowed to disable without root, did not make such a huge difference (+15% approx).
  To continue trying system app disable capabilities are needed, if your cosmo is rooted you can disable system apps but when restarting they are back, the way I used was through TWRP (unofficial), installed it on the second boot (renaming to twrp.img and using cosmo installer), when booting to twrp it has system privileges, so in twrp mount system and rename system apps (in priv-app folder) from *.apk to *.bak. I started with the google core services (GmsCore) another (+10%) the codi updater (STFlash) almost no difference with this one but it is a little annoying. Finally Baidu_Location and this is the one that gets the big price (+40%).
  So right now my cosmo has disable all no major google software, all planet software, baidu_location and stflash and it goes up to 5 days of normal phone use, 3-4 phone calls a day, 5-6 emails, some random web browse and 10-15 min of video a day.

  The question I have in mind is what could happen with a clean android like AOSP?
