I think 350 mAh battery vs 450 mAh inside d5 and x series can’t be improved by a firmware update…
@Mauro_S true - but battery management can.
This is what the problem is here.
Sure - there may be some hardware limitations but as yet we can only work with what we’ve got and see how it turns out.
The firmware - if it’s any good - could make this watch a very reasonable device indeed.
I watched yesterday the KW88 YouTube video…pretty nice comments from smartwatch ticks about the KW88…any new video or review on this watch?
