I want to buy one, but even if a few people complain about it, I'm going to wait for the problem to be resolved completely before I get it.

I'll add some information. I have tested a replacement unit. Exactly the same: 10% drain in 8h overnight (supposedly Off).
I hope Gopro listen us and fix this issue.
One question. What card do you use? It is the only thing that they seem to consider.
I'm using a sandisk extreme 64GB (one of the recommended list. Part number already checked)
Maybe we can find a correlation if we share our sd card model...
Anyway, this is not the solution but it can help to find a workaround...

I think I have found a clue in this battery issue which could explain why not everybody is suffering it. And why sometimes our own gopros have no battery drain.
PLEASE TRY IT AND SHARE YOUR EXPERIENCE!
I have found out that the amount of standby drain DEPENDS ON THE AMOUNT OF DATA STORED IN THE SD CARD AT THAT MOMENT!!!!
A brief explanation. My usual test is recording some videos around 10-15 min, write down the battery level. Then turn it off and some hours later (sometimes 4-5 hours, sometimes 12-14 hours) write down again battery levels. Without removing the battery at any time.
And as soon as sd card is getting full of this test videos I format it.
But then analyzing my data I realized that standby drain in the first tests after formatting sd is much lower than the later ones! By far.
For example, I can have 10% in 8hours with sd half used, and tonight after a fresh format I’ve had 1% in 14hours (as always wireless, voice control, GPS off, but this time quick Capture On)
And somehow this makes sense. Depending on how you use your gopro, you’ll never notice this battery drain. For example if you just format/erase your sd after each video session.
Unfortunately, in a real world scenario, in a summer trip, you can’t download and erase your files, so we still need to fix this issue. (in case I am right and pointing out a candidate)
If possible it would be nice if some affected users can try it and compare its draining if they have a freshly formatted card instead of full of videos (same wireless, GPS , voice control OFF)
If this is confirmed then we’ll have a starting point. There are two options:
- That this drain happens in all brand of sd cards
- That only happens in some sd card models.
If we share our results we could identify this. And maybe gopro will fix this if it is not what is expected.
@danielr15 I’ve seen from your posts that you usually download and format your card. If my guess is correct, then this procedure could mask the battery issue. Could you please help us doing the reverse operation? Take an almost full sd card and then WITHOUT ERASING ANY FILES AND WITHOUT REMOVING BATTERY TURN IT OFF and leave it some hours?
It would be very helpful as you are one of the unaffected users.
It is important not removing the battery, since in this way any software loop will be terminated and probably there will be no battery drain masking any issue. But I’d like to emulate the normal behavior. Turn it off after using it.
PS: Disclaimer: Despite being a firmware engineer, I have no clue on how gopro systems are programmed. I am just having a guess based on my data. So I apologize in advance if experimental data proves this hypothesis as incorrect. But at least I have some hope that it is related….
PS2: A particular case is when there is no sd card. In this case I have seen erratic results, but my guess is that could be a different bug. Actually, at least in my gopro with no sd card when I turn it off, it takes more than 10 seconds to disable screen after the 3 beeps… So I expect that this is not working nicely anyway.
PS3: My card is in the list: SanDisk Extreme MicroSDXC (UHS-I / V30) A2 64GB SDSQXA2-064G-AN6MA
