Lineage OS Random reboots

[Murks]

Hi
I have the latest Lineage OS installed on my FP2. Since some previous updates I encounter random reboots, mostly after charging the phone. 5 to 8 reboots with some time gaps in between, then it works fine.
Since this was already an issue in 2017, I wonder why it is not fixed yet. This is really annoying!

What does the Android 7 Fairphone OS bugtracker link have to do with it?

Else … the maintainer of LineageOS on the Fairphone 2 might see your issue better over here …

Lineage 17.1 - FP2

Official Lineage 17.1 is out for the FP2. This thread is to discuss stuff that does NOT work ONLY ! https://download.lineageos.org/FP2 If you have installed gapps, do not forget to flash new Android 10 gapps at the SAME time, otherwise you will BREAK your stuff (like on previous upgrades). Chris Note: There is also a lineage recovery available that can be used to flash lineage and gapps. It does not support data partition decryption (either). Note: Do not upgrade from unoffi…

Lineage 17.1 - FP2

Some news about some ongoing issues: Now there are three FP2s under LOS 17.1 in my family (let’s call them device A (mine), B and C), so we can do further testing about the current bugs. FYI: Device A has magisk and is rooted, device B has magisk and is rooted, and is encrypted, device C hasn’t got much more than basic LOS, just a few apps but that’s about it. Mobile data issue I had it quite often again lately, but it is again random. We have observed the same bug on the three devices. When …

Seconded.
LineageOS isn’t developed by FP. And if you are talking about the firmware files of the FP2 (since the problem is probably related to this somehow), I’m afraid they won’t receive an update anymore, not if Qualcomm doesn’t want to (which is unfortunately the case).

Thanks for the information. Since I’m not a developper, I’m just wondering why the problem of random reboots persists since 2017. I have no idea if the origin of the problem is the same. Lineage OS, FP2 … I’m just the user. I switched from FP2 OpenOS to Lineage two years ago, and I have the problem since a couple of months. In my opinion it must have come with one of the updates?
Nevertheless: Happy New Year!

I’m just wondering why the problem of random reboots persists since 2017

One reason may be that there’s a myriad of reasons for the reboots. You’ll find a lot of them here if interested…

A little Guide to... Random Reboots

This collection of troubleshooting advice for random reboots was formerly the first post of this topic (please continue there if you have questions about the guide or want to share your experiences). I now made it into its own wiki topic and gave it the unique tag #rebootsguide to make it more visible (and hopefully to encourage people to keep it up to date). For troubleshooting reboots on FP2 you may also have a look at the official support pages and select → Fairphone 2 → phone reboots there. …

Hi Volker
Thanks for the Guide and the Support Link. Meanwhile I have bought a new battery and the problem is still there. Also the latest LINEAGE updates didn’t change anything. I’m now pretty sure that the rebooting is connected with the charging level of the battery. If I charge 100% I have up to 10 reboots within 2-3 hours, after that it works fine. If I charge up to 90% I have less reboots. I will try to find out charging limit to exclude reboots. Unfortunately that means I have to stay with my phone to disconnect the charger in time.

Hi Markus, maybe this helps you, this app stops the charging by itself…

Battery Charge Limit | F-Droid - Free and Open Source Android App Repository

Lineage 17.1 - FP2

I continued to use LOS 16.1, have spared me the installation of 17.1, because I expect me more no improvement in stability But I can give you one suggestion: If you have root access you can try Battery Charge Limit the program will stop charging before reaching 100%. I have set it to 92%, and I believe at least that my reboots are less.

[Volker]

It’s a good app. But you should keep in mind that it needs root access to work correctly.
