Because it is mentioned so often like it is a general problem …
I have no noticeable battery drain with LineageOS (migration from unofficial to official build didn’t make a difference).
And I had no noticeable battery drain in Fairphone Open OS (apart from when I left the camera App on).
I didn’t take any extra measures to get there like taming WiFi or installing some battery optimizing App or something, battery life for me was and is just normal.
So there’s a fair chance that if you don’t have a problem with it in Fairphone Open OS, you will not have a problem with it in LineageOS.
I think that’s a very good question! And I think we as a community could write a wiki post describing that (it is also subject to changes). Not sure how that works with this forum or where to start. I guess a decent start is looking at the changes between Android 6.0 and Android 7.1.2. Where else could one look?
Here’s my first attempt feel free to edit:
Battery Saver can be enabled from 25%
No longer can disable either 2.4 GHz or 5 GHz (whole WiFi needs to be enabled)
Now that I think about it though, might become a large list (too noisy).
I’m asking as I’ve learned today that BLOCKS2 (btw. I’m still waitng for may watch but they doing a hard but great job) is going to do more or less exactly this by founding the project OpenWatch.
They are going to cooperate with
Team Carbon as well as some of the team behind Lineage OS
what allows to use software dev. resources in much more efficient way. That would enable Fairphone to shift manpower from software to hardware and sustainability promotion.
Thank you for your question. As said in one of the topics you linked to: at Fairphone we are very impressed by the work of the community and we believe that their work is a huge contribution to the longevity of the Fairphone 2. Successful alternative OS’s for the FP2 will enable users to keep the phone longer and prevent ewaste.
That said, there are currently no plans to support LineageOS officially. The team has their hands full supporting the existing two OS’s and has no resources to support another one. Let alone the required pressure it would put on the legal, product, communications, marketing and support team if Fairphone start supporting a third OS…
But to explain a little further: the Fairphone ships with Android with Google services; Fairphone OS. If you want to sell many phones in order to achieve impact in the supply chain, there is currently no other option then to use standard Android. The majority of people expect a standard OS that works out of the box with the apps they use and need.
If we look at the number of people that currently use alternative OS’s on their FP2 it shows that only 5% changes the default OS to something else (Fairphone Open, LingeageOS, Sailfish or Ubuntu).
Making Fairphone Open is a small effort for us as it is very similar to Fairphone OS and puts little pressure on the teams capacities. Supporting a whole new OS, like LineageOS, is really no option.
I replying a bit late, but after some hesitations to switch to LineageOS, I have to say, my FP2 is running much better with Lineage OS and the little improvements of Android 7.1 are welcome.
I’ve not a single issue with LineageOS where with FPOS or FPOOS I had some.
I agree if we talk about the main OS where commercial aspect come into play.
If FP would cooperate with the dev. community a way closer they won’t need to rely on the good will of the community as they are part of it.
The community achieved quite a lot whereas FP seems to fall behind in terms of long term usage of the Fairphone. Thanks to the community I’m able to run Android 8 on my super old Samsung SII whereas Fairphone still runs on 6.
I agree that should not just port the LineageOS source to Fairphone but rather contribute actively to the source in order to push FOSS Android. There are some suggestion above in this regard.
It would be quite a message if FP would do so.
