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?
