I have been getting very bad battery life since I had my KW88 2 weeks ago. The watch will not last more than 7.5hrs.
I tried turning on flight mode, but there was no significant improvements.
I was so disappointed that I decided to order the newly released finow X3+ to see if it was better.
Three days ago I came across another battery problem thread. I decided to give it a try.
Following recommendations by +Tony Bunn and also turning off the show time on wrists movement, I managed to get more than 16hrs of battery life.
The battery improvement could solely be attributed to disabling wrist movement monitoring. Can someone please try it and report the battery life, before running any of the battery calibration apps.
And now with the new found way to add custom watchface to the kw88, I am really starting to love this watch.
The X3+ looks good and feels very well built, but it’s very very heavy compared to the KW88. Will need more time to check out the battery life on the X3+.

All, I have had some success improving my battery situation with the KW88.
There are two apps in the play store that work without ‘rooting’. First I ran: Repair Battery Life PRO which is free.
This scanned and found a lot of low cells and quite a few inactive within the battery. I then selected repair, the app then (apparently) ‘fixes’ the reported discrepancies and when retested reports all healthy.
Then I ran the second app: Advanced Battery Calibrator, also free:
This seems to reset the charge memory in the battery. You then have to switch off the watch and recharge until 100% before switching on.
After this the watch ran all night (radios off) and only depleted to 97% by the morning and then ran all day with wifi on for an hour and then sim enabled for 4 hours. It then shut down by 17:00 - I didn’t see a transition to battery saver mode as I was busy with work and didn’t see the % state before it shut down.
However, in summary, I got a lot more life than previously. To be honest I was half suspecting these apps to be either ‘snake-oil’ or exaggerating their efficacy, but it seemed to make an improvement for me. Hopefully this might help others too. Tony )
