Since version 4.90, the battery life of my Venu SQ Music has gotten much worse. Normally 7-8 days without activities/music was possible, now maybe 4-5.
When I have a run together with my wife (she has a Venu SQ) for about 25 minutes, her SQ's battery drains about 5%, mine about 23%(!).
Nothing has changed in the watch settings.
Some versions ago I noticed the same and eventually it got fixed in a software update.
