About mid day my battery suddenly shows that it is dropping 1% every 30 seconds or so when the display is on, at about 9 hours it goes into battery saver mode showing 12% or so. After cold booting the watch- it shows the percentage back at around 60% and works normally. This just started happening about a week ago. I’ve had the watch for about 2 months. Any thoughts?
I have had this happen before also . A full reset after software update did the trick for me . On another watch ( but many years back ) i used one of the playstore battery cailbration apps , i was warned it wouldnt work but it did 
. Unsure if these things are still around and work

It can help Tim.
In android 5.1 you could wipe the battery stats and get results but Android 7… I’m not sure if it is a plecebo effect because you need root access for wiping battery stats now…
My advice is also make a factory reset followed by a full charge and then complete discharge.
Do this a couple of times to see if it is a battery problem.
I have to say though that it is a small battery in the kw88 pro and around 9 hours is not bad.
