fastboot PLUS charging issue

jollamate — Fri, 27 Nov 2015 10:24:06 +0000

since three days my phone is stuck in fastboot mode. i tried to get it into recovery mode, but it doesn't charge to survive long enough pressing low volume key -> insert batt -> pressing on-button. on the "charge screen" the lower symbol (s- or flash-shaped) is underlayed by some diagonal stripes. I've "charged" it over a whole night but it didn't help me to charge it enough.
any idea what's this issue? internal usb charger broken? battery gone? i don't have a jolla battery charger (anybody at all?) so i can't verify if it's "only" a battery issue.

Tested: Alien Dalvik Stop = Better battery Life

Hamano88 — Fri, 11 Jul 2014 11:15:27 +0100

In thelast three days ago, I have been testing this App 'Alien Dalvik Stop', it does exactly what the name says.
My results with the battery drain have seriously changed. My Jolla survives longer and I would have more juice at the end of the day.

My question is, does it actually effect the phone in any negative way? Because in android if you use app killers it really effects the phone negatively.

The way I'm using it is by closing android apps after I'm done then I kill dalvik. According to Crest a, CPU tracking app, it shows how dalvik is always running in the background using the CPU intensively.

Only thing that changed is instead of the android apps works in an instant it takes a couple of seconds, I don't mind it because the huge battery Jump is worth the sacrifice.

Any thoughts

Intermittent Shutdown/Reboot Issues: SOLUTION

JollaTides — Mon, 12 May 2014 13:14:11 +0100

After almost 6 months constant use I recently started getting problems with my Jolla handset doing either of the following:

1/ Handset would warn of overheating issues and shut down

2/ Handset would randomly shut down

3/ Handset would occasionally enter a boot loop cycle where the only way to stop it was by removing the battery

These problems all seemed to appear at the same time and thus appeared to be related.

After some reading around, I cut some strips of electrical tape to match the depth/width of the Jolla battery and stuck 2-3 strips to the bottom end of the battery.

Since this mod was carried out, I have not had one incident of points 1-3 listed above in over 1 week testing where before the issue(s) occurred on a daily basis for at least 2 weeks prior.

I can therefore only assume that all points 1-3 are interrelated and the cause of the issue(s) was due to the following:

Over time, the battery connector points become less rigid and there becomes more play or wiggle room with the battery pack. This can cause an intermittent connection which causes the phone software to react in a strange way.

By adding the strips of electrical tape, the battery fits very tight and there is thus no room for this issue to occur.

I would suggest that Jolla can easily fix this time-related issue by increasing battery pack length by a very small amount as illustrated by the result of this rather basic modification that seems to have solved the 3 issues I experienced. Or alternatively the issue may be solved by a software patch if indeed the software is reacting strangely to this hardware related point.

Has anyone else experienced this and can confirm or comment either way?

Temporary + Permanent Fix For Battery Drain Via Terminal!

For temporary fix, type into terminal:

devel-su
systemctl stop tohd.service

Password is whatever you set in developer area of settings menu.

This will require entering each time after reboot.
______________________________________________________________________

For permanent fix if you're happy with the results, type into terminal:

devel-su <- you command your terminal to enter developer superuser mode
(your password) <- note: invisible writing. Jolla confirms that you are the superuser
systemctl mask tohd.service <- you put a mask to a buggy service commanding NFC chip
systemctl stop tohd.service <- you stop the service
exit <- you leave the devel-su mode
exit <- you leave the terminal (it closes)

________________________________________________________________________

If you ever want to restore to original settings, you can use the following code:

_________________________________________________________________________

devel-su <- you command your terminal to enter developer superuser mode
(your password) <- note: invisible writing. Jolla confirms that you are the developer.
systemctl unmask tohd.service <- you take the mask away, so the system can find the service again
systemctl start tohd.service <- you start the service
exit <- you leave the devel-su mode
exit <- you leave the terminal (it closes)
_______________________________________________________________________

Report here if it works for you! :-D
