Hi All!
First of all, I want to note that this post should be a collection of experiences I had with my Jolla over the course of the last two years concerning the/multiple reboot bug(s) with my phone. I know there is a whole thread addressing this problem but it's stuffed with so many things that a short note of mine will just drown in all the conversations.
I hope these notes can help somebody with the same bugs/errors. Please feel free to contact me if you have any questions. So lets get started:
History:
- I bought my phone back in 2014 at June the third. A pretty late model of the Jolla even it states "Device-Adaption: 1.0.0.7" in the settings.
- Around eight months later I got introduced into the reboot glitches the Jolla suffers from. First it was only a rare case but after time it happened more and more often.
- I started to search at together.jolla.com after the issue and found a thread quickly: https://together.jolla.com/question/7144/jolla-randomly-shuts-down/
- I followed several tips that could solve the problem including:
- Adding a piece of paper _under_ the battery
- Adding a piece of paper to the bottom of the battery to push it further into the pins
- Adding two pieces of smaller strips across offset to tilt the battery a little bit (even further that method one)
- Cleaning contacts (on battery and pins)
- Updating Software (up, down, early, reset, etc.)
- All those tricks seemed to work at first but after a couple of days the problem occurred again. Again slowly, a few times a week but increasing over time to about several times per day.
- I decided to sent my phone in for repair. The request was made by me on 04.09.2014 but I backed off because I could not spare my mobile phone for repair for two weeks or so.
- Time passed and I lived with the bugs/random reboots
- I opened a new support request on 08.07.2015. This time I really sent in my phone. After some kind of painful answering of template emails from the support, I could finally fill out the shipping form from FedEx.
- After two weeks or so, my phone came back from Finland and I was kind of disappointed. All they did was a more professional looking version of the fix with the two small strips of paper on opposite sites of the battery.
- Sadly, as already described above, this official fix did _not_ work with my phone.
Today:
Some time and updates passed since the last events (yeah even a crisis since then!) but the problem still exists. Especially if the phone has to do some heavy lifting for example cellular actions or navigation (Display on max brightness + gps). The phone seems to have two kind of reboot bugs;
One is the known reboot, where the phone simply resets to the Jolla boot animation and reboots and another one is that the phone simply shuts down - hard - until you hit the power button again (like after your battery ran out of juice and you just plugged it into the charger).
For me, the reboot seems to be some hardware issue with some kind of brownout detection killing the phone because battery voltage drops under a certain level - all caused by bad connection pins from the casing to the battery of the Jolla). The secondly described bug seems new to me and I don't know why it happens.
Today I sent in a new repair request since my phone should still be covered by warranty. I'll keep updating this list with recent events and try to document it as well as I can.
- 06.05.2016: Sent repair request describing the current problem with my phone and all history to it.
- Waiting for jolla care to reply
Technical data:
As martonmiklos suggested, here are some technical values from my battery: β: -0.301 α: 4.230 σ²: 0.911 Pass criteria where: β > -0.3 and σ² > 0.85 since beta is a little bit smaller than the required value, the test failed on my device. Battery was up to 90% when the test happened.
If you find some strange or heavy mistakes in my writing, feel free to ask me to correct it or correct it by yourself (since this is a public wiki).

I totally agree, and it is what I said many times: reboots are not caused only by pins of battery, but Mainly by a lack of power when using some apps and processes that use much power!
palikao ( 2016-05-07 11:12:45 +0300 )editOn my device the reboots stopped when I replaced the battery last year - unfortunately they are now returning - so it seems after the battery lost a bit of its original power (after a bit more then 6 months using) the is sometimes a lack of power in peek situations and the phone is rebooting ... Weird
elastic ( 2016-05-07 11:37:35 +0300 )editThis is spot on. I have been experiencing the same thing too - either the phone powers off abruptly or reboots. It would be nice if somebody would clarify if this is a hardware or software problem!
sifartech ( 2016-05-07 14:43:08 +0300 )editI have one of the preordered Jolla phones from December 2014 and it also says "Device adaptation: 1.0.0.7". I doubt this is any indicator of the hardware revision.
