Battery saving mode all the time

Sailfish OS (5.0) UI allows to start the battery saving mode / power saving mode at will from the Battery setting menu, and to set a threshold from which the battery saving mode is automatically enabled. This threshold can be chosen between 20%, 15%, 10%, 5%… But not higher than 20%.

Even if this mode isn't saving much battery, if you want to have it set all the time you can use this commands from the Terminal :

devel-su pkcon install mce-tools # to install the package that contains the mcetool command line program

mcetool --set-psm-threshold=100 --set-power-saving-mode=enabled --set-forced-psm=enable

This second line enables the power saving mode and sets it to auto-start from 100%. This way you'll be using your phone in power saving mode all the time except when it is plugged (loading the battery).

This setting is kept even after a reboot, just like if you had a 100% label available in the graphical Battery settings to click on.

Blocking phone numbers from CLI in Sailfish OS

Blocking phone numbers from CLI in Sailfish OS

---

With Sailfish OS 5, it is now possible to block incoming calls, which is especially useful for unwanted calls such as spam calls.

From the SFOS UI

• in the Phone application, go to "History"
• then long press on the phone number you want to block
• then select "Block Number"

Next time this number calls you, it will go directly to your voicemail, and you'll see it in the calls history with a "blocked" icon:

Using the CLI

You can also do this using SFOS CLI, which comes with the benefit of being able to also specify ranges of numbers - useful for countries where sales calls are due to originate from specific prefixes.

For instance in France, those numbers start with +33949 (and a bunch of other prefixes).

To block this range in SFOS, I would type the following command (as defaultuser user):

dconf write /sailfish/voicecall/filter/rejected-numbers ["'^+33949'"]

and to check that this was taken into account:

dconf read /sailfish/voicecall/filter/rejected-numbers

"Reject numbers" vs. "Ignore numbers"

If you're curious like me, you've probably seen that there are 2 options when it comes to filtering numbers in SFOS. If you enter that command:

dconf list /sailfish/voicecall/filter/

you'll get 2 answers:

ignored-numbers
rejected-numbers

We've used rejected-numbers above, now you may wonder what ignored-numbers is and what's the difference?

Well, fear not as I tested it for you:

• rejected numbers will send the call straight to your voicemail, without your caller even getting a ring on their side,
• ignored-numbers will still send the call to your voicemail, but after the usual 4 or 5 rings for your callers
  • you will still see the call coming in,
  • but your phone won't ring,
  • and the call will also appear as "blocked" in your calls history

Import settings for France

dconf write /sailfish/voicecall/filter/ignored-numbers "['', 'anonymous', '^+33162', '^+33163', '^+33270', '^+33271', '^+33377', '^+33378', '^+33424', '^+33425', '^+33568', '^+33569', '+3364466', '+3364467', '+3364468', '+3364469', '+337568', '+337569', '^+33806', '^+33948', '^+33949', '+5909475', '+5949476', '+2629478', '+2629479', '+5969477']"
