Battery drain of new SQ2 music edition device

Battery drain of my Venu SQ2 in 4 days.

Bought the watch on 17th Feb 2024, battery does not last more than 4 days. GPS mode only when walking. Not used Spo2 as well.  Any tips to improve?

Have reached out to service centre, they ask for the device to be sent to troubleshoot further. Not a pleasant experience with the new device
