I currently have 23.12 installed on my Fēnix 8 47mm AMOLED and the battery's till drains crazy fast like it has been doing for a few weeks now. Before I had 19 days average battery life and now I have to charge every 10 days. Updated to 23.12 yesterday, charged it to 100% and today I have 86%. GPS is off, Touch is off, SAO is off, only light on gesture is on.
Garmin has introduced a new update for many of its high-end smartwatches. Rolling out now, the new update is said to improve battery life while also addressing bugs that hampered voice calls in recent updates.
