Massive Battery drain on Vivoactive 4 #181

Closed marco123445 closed 3 years ago

marco123445 commented 3 years ago

The Battery drain on my Vivoactive 4 is massive since a recent update

LibertyBeta commented 3 years ago

I'm seeing similar drain on my VA4 as well as the Infocal face, which uses a lot of the same code.

mkuthan commented 3 years ago

The same for Vivoactive 3, version 2.4.3. Unfortunately I don't know previously installed version.

zigford commented 3 years ago

Same here. Any logs I can gather to help? Love the crystal watch face

warmsound commented 3 years ago

Hi guys, thanks for reporting this issue, and sorry for the slow reply. I have a VA3, and I'm monitoring the behaviour on my watch. A few initial questions:

Thanks for your support and help,

Vince.

Forerunner 245 and a (now returned) VA4. New clean installs. Stock settings.

Saw around 2-4% hourly drain verses 0.5% on stock watchface.

warmsound commented 3 years ago

@LibertyBeta After a fresh install on my watch, battery dropped 4-5% within the first hour, but then stabilised to the usual ~0.5% per hour. I assume your high hourly drain is continuous?

zigford commented 3 years ago

I'll do an overnight test with mine on stock settings. I got my VA4 new earlier this month, so I think I installed crystal fresh and hadn't gone through the watchface update.

LibertyBeta commented 3 years ago

@warmsound Yeah, drain never normalized back down to ~.5%. Checked overnight as well, same. Rough drainage stats. I charge on Fridays, so I can test again end of week if that helps.

zigford commented 3 years ago

Overnight with stock setting it worked fine at .5% battery drain per hour. Which heart rate setting affects battery life more the normal one or the live (5s) one?

warmsound commented 3 years ago

My VA3, firmware 7.40, Crystal 2.4.5, has lasted just over a week before needing a charge, so I haven't been able to reproduce the problem.

However, I've found this thread for the VA3 7.40 firmware where high battery drain is reported generally (e.g. dead in 10 hours), so it's possible that the firmware, rather than Crystal, is the root cause. High battery drain also reported on this thread for the latest VA4 5.10 firmware.

What firmware is everyone running?

It would be interesting to know why only some users experience the issue, and whether a watch face can do anything to make the problem worse.

@zigford the Live (5s) HR setting will drain the battery more. The difference is in low power mode: assuming you're showing seconds, the regular HR setting doesn't update the screen at all, so only the seconds need to be drawn each second. With the 5s setting, every 5th second, both the HR figure/dot and the seconds need to be drawn. The CPU time required to update the screen is related to the area of a box that encloses all elements that need to be updated, so every 5th second, there's a bump in the CPU time required. So the 5s HR value (as opposed to e.g. every second) was chosen as a compromise. In any case, CIQ has a hard limit of 30ms per frame, averaged over a minute. Crystal takes ~5ms per frame on VA3, with Live (5s) taking ~31ms every 5th frame. (vague here, as I used to think the CPU time was directly proportional to the area of the enclosing box, but that no longer seems to be the case.) Probably more info than you wanted... 🤓

Thanks @warmsound for the detailed info. I’m starting to think the problem is for all third party watchafaces on this firmware. I’ve found another bug that only affects third party watchfaces. The hydration reminder always crashes when accepted if a third party watch face is active. If a built-in one is used it works fine.

I’m testing drain between various other faces and so far the difference is quite dramatic when compared to the built-in ones.

I haven’t been able to repeat my previous overnight test with crystal consuming ~.5% but I was attempting to use a light theme which I suspect uses a fair bit more power. On light red, I haven’t been able to get battery drain below 1% per hour.

Checked the CL for the 6.x beta for the 245. No response yet on if this CIQ bug is fixed yet. -- Rainer Paskiewicz

Some facts:

zigford commented 3 years ago

New update available with note

Fixed some scenarios where battery drain can occur on Connect IQ watch faces

my gut feel is it’s related to the hydration tracking crash that happens with CIQ watchfaces.

Time will tell.

Thanks all for the update on this - let's hope the firmware update solves the problem 🤞
