I would like to submit to the community my case: I purchased the JP1 with SFOS2 ( installed. I noticed, with normal use, not intensive, that the behavior of the battery is very strange: it is discharging by 20% in just 1 hour of use (3G), and hardly, starting at 8 AM, I can reach 10 PM with my JP charged.. I would expect to make 1,5 days..

I have only WhatsApp (Android) on autorun.

Here are some screenshots (for 2 days and 4 days).

I also have strange battery behaviour (2.0.0.x and 2.0.1.x) Btw, what app are you using to show battery life?

These screenshots are taken from System Monitor app, a SFOS app

Same problem here now! Since one week I have a massive problem with battery drain. In test case battery is 100% full, and phone stays in my pocket most of the time during working hous. But after 8 hours it is nerly empty.

Tried following, but did not help:

  • Disabled Situations autostart
  • Restart and kept all Android apps closed (especially Whatsapp)
  • Bought a new accu, because I thought it is damaged
  • Rebooted multiple times

No solution after all. What makes it strange, is installed this a month or so, but problem exists only a week. Any new ideas?

Maybe I've figured out the problem, at least in my case. After disabling the mobile data connection, battery drain was gone. But this is not a steady solution for me, because it was never a problem in last year. So I did a little investigation and accidentaly I see the message on terminal:

Letzte fehlgeschlagene Anmeldung: Mittwoch, den 02. März ... von auf ssh:notty
Es gab 5325 fehlgeschlagene Versuche seit der letzten erfolgreichen Anmeldung

So there is someone or a bot on the net, trying to attack my phone. And so sshd causes CPU usage, GSM modem is working the whole time and drains my accu.

  • Why is sshd open on mobile connection?
  • How can I figure out if someone had success and entered my phone? Unfortunately there is no /var/log/auth.log
  • How can I block all open ports on mobile connection?

I would have thought mobile connections to be behind NAT to prevent this kind of stuff.

If you are 100% you are not giving your IP out via some app to someone who has grudge on you, you could contact your operator and ask them to give you new IP and/or block the bot's IP and the bombing should stop. But it won't work if some of your apps/services leak your new IP to the bot.

well, if you're with Deutsche Telekom / T-Mobile you get a public IP Address without NAT, so you may be attacked accidentally .

I can login to phone via ssh when I use the ip of 'rmnet0', so it is sure a public IP. Now I'm trying to setup iptables to get rid of this problem and also avoid misleadingly open ports by apps.

But in my opinion an all ACCEPT policy is a completly disaster of sailfish OS!

Well Port Sentry or Fail2Ban could slow the attacker down, but doesn't remove the problem...

Actually I can confirm failed ssh login attempts on German T-Mobile/Congstar network. You can check via journalcl | grep ssh

I'd guess i would help to switch sshh port away from the standard port 22 to e.g. 2222. However I'm worried of side effects.

My case is similar.

Android support, WLAN, BT, GPS off. 2G. Only I have set the alarm. Interestingly, after the reboot suddenly the battery level increased by a few percent: / It is my first contact with this situation.
