Loving the battery life on the Ultra so far even from the Series 7 45mm. Been in use for 46 hours so far from a 100% charge and I still have 28% left, should be able to squeeze close to another 24hrs out of that. My usual use is text messages, email, get quite a few notifications daily, package tracking, using the timer if cooking and controlling my home with the home app so nothing really demanding.
