Well I’ve had an interesting couple of days with my KW88. Having been as disappointed as many with the battery life I resulted to switching to 2G with everything else off - this gave me a full days use with SMS for staying in touch - still not great.
I emailed Kingwear and gave them stats on how little life I was getting and asked if it was a known problem and if there was a fix (battery or firmware). The overseas Marketing Director gave me this response within a few hours.
The battery has been well improved. Please send the feedback to the reseller whom you bought the KW88 from, so that the related sales will do the after sales services.

So I contacted the reseller who’s a seller on AliExpress. He was super responsive and used watsapp for a long dialogue. My firmware version was 20160719 (19th July 16) and he gave me an upgrade to 29th July version (files are dated 30th July)
After a lot of toing and froing and help from Shenzhen, I finally downloaded it and flashed it into my KW88 - happy days.
it remains to be seen how much this addresses the battery life, but its supposed to help significantly.
Really happy with the watch and the capability it has, and well impressed with the support from Kingwear and the Chinese reseller.
Will keep you posted.
This may be old news, but thought it was worth sharing with the community… :O)
