In use battery life is largely the same, though Intel has added some additional features with 12th Gen Intel Core that can improve in-use power consumption in some scenarios. The main optimizations we were able to land were in standby power consumption. For Windows users, this means longer Modern Standby before going into Hibernate. For Linux, more importantly since hibernate is atypical, it means being able to leave your laptop unplugged for much longer when not in use.
