Upgraded to a new 955 Solar, battery life does not last longer than 9/10. I have restarted the watch, i use a basic face watch, the Oximeter is set on demand only, i don't have any other gadget linked. If i complete an activity it will lose 5/8%. Solar part doesn't charge or keep the battery charged therefore also not useful. Not suitable for long distance races or to wear as normal watch as you are constantly charging it . Any suggestions are appreciated
