24.12 Forerunner 955 Battery Drain

After the 24.12 software update, the battery life is terrible during normal usage (around 5% per hour). The watch doesnt even last the full day. 

What's strange is the battery drain seems normal during activities (Running / Biking )

Here's what i tried: 
1. Hard resets 

2. Connecting to Garmin Express and updating

3. Power Off / On the watch

4. Factory Reset

5. Downgrade to earlier firmwares

6. Removing the folders in GARMIN/ folder and resetting the watch

Even after trying all this nothing helps. Really frustrating as the watch is barely an year old. 
Has anyone else faced the same issue? i have contacted Garmin support and i dont think it'll help much as the watch was purchased in the US and im currently in India
