Not going to correct as the bars are a visual indicator only. Unless the Instinct is any different, there is likely to be a percentage shown when connected for charging. That's a far better measure of usage.
Yeah, no percentage anywhere on this thing, probably the top requested feature to be added everywhere you can find reviews, including this site.
So... you're saying that 1 bar <=20%, I had assumed 1 bar >=20%. I would tend to want to disagree with the former as that would logically mean that as soon as you go from fully charged (100%) to 99%, then you would fall into that criteria and therefore very quickly lose a bar within hours after unplugging the charging cable (and falling from 100% to 99%). However, I can't speak with certainty that the latter is how it is coded... which I guess would be yet another request to have a percentage reading in this thing somewhere at least as that would very easily clarify this.
I would note that I have also noticed about at least a bar a day, if not more (about 4 bars by the 3rd day), but that was before I've done a full reset (last night at the last 100% charge). I'll keep wearing it as is and just report back I guess over the next couple of days I guess. However, at this rate, 5 bars means 2 days under 1 week, and only with just about every feature disabled, so that's not good.
Also, for clarity, I've determined full charge to 100% 24 hours ago by charging until the animation stops, per info I've found elsewhere on this forum.
Anyone else have any other suggestions or things to try, please let me know, thanks!!
