I updated to the latest 16.10 build of LO and I notice huge improvements on the battery side. The phone lost hardly any charge yesterday and the indicator is predicting 6d (yes, six days) battery capacity. Good Work

a little update from side besides that most people are of the opinion that battery life depends heavily on mobile network signal strength.
I’ve made some contradictorily experience in this regard.
Although the signal quality is mainly good predicted battery life is shorter as when signal quality is mainly bad.
shorlty aftwards the signal quality was mixed but battery lasted a way longer
After I had done the last screenshot I used the phone a bit but put it aside a couple of minutes later. That triggered something what caused the battery to drain as shown in the screenshots above but I cannot explain what it is.
Any troubleshooting with BBB and the support of the guys moderating [APP][2.1+][7 jan. - V2.2.2] BetterBatteryStats on XDA didn’t help either.
Unfortunately I don’t have an app what shows me app etc activity history (not as a summery as in BBB), so I could narrow down the trouble maker.
Does anyone know a proper app?
My hope lies know in Xposed and Amplify, what can know be installed on LineageOS run FP2

Well, in the first two pictures, bbs wants to tell you that the phone didn’t sleep for a noticeable time. Whether this matters depends on the specific wake locks or other events it’s reporting.
Also, in my experience, i have a high variance of battery drain while sleeping, ranging from .1℅/h to 2%/h… I couldn’t nail this variance…

actually those are screenshots.
Battery drain is a way more than .1℅/h to 2%/h.
I need some tool what shows me activities per point of time not as a summery for a specific period of time. That would be very helpful to narrow down the consumers.
Sure these are screen shots, but you notification bar shows a notification from bbs. Not in the third picture.
The drain i was referring to was the idle drain

I totally agree, best battery life ever on FP2 with 16.10 build.
I can only add more enthusiasm for this build: A long (10h) train journey yesterday hardly drained the battery compared to older LO builds despite all the power consuming factors of a train journey: Lots of mobile transmissions because of the cell changes when the train moves, data use, WiFi, listening to Music, tethering for my tablet etc.

how?? still draining battery, but I almost no apps runs in background.
Trying to limit wakelocks by means of Privacy Guard but don’t see an impact
Well, my usage today resulted in the following observation: while using, at least in some apps, the phone was noticeably warmer. I don’t know whether i should try to investigate or wait for the next weekly, as it is known there’s some wakelock issue (though wakelocks shouldn’t matter while display is on, by definition)

Nobody said that next weekly would fix anything
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 before 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.

Well, of course everybody expect the next weekly to fix everything
We’ll see what next Tuesday will bring
(This means, of course you’re right. BTW, in my setup i don’t experience a stray wakelock.)

I flashed the latest modem-17.09.03.zip (baseband 4437.1-FP2-0-07) today and get considerable more battery drain than with modem-17.07.06.zip (baseband 4436.1) that I was using until this morning.
Since the update today i habe the most amazing battery stats since i have my smartphone 1 1/2 years ago! I’m impressed!

Since the search function doesn’t show a reference to it in this thread yet and I just remembered …
Be aware of the performance profiles of the battery saver settings.
When I installed LineageOS i did set the profile to “Efficiency”.

Can you share your settings in:

I didn’t read the whole thread, but it seems I also have a high battery drain with a new FP2 and latest LoS. I flashed the latest FPOS before switching to Lineage because of the modem files (dunno if I was right). What are suggestions to improve battery usage could someone give a short summary ?
Thanks,
Singu
I guess that is one way to get the latest modem files, but it’s not practical to do for every update. You can just download the latest files here: #modemfiles and flash them via TWRP.
