Pixel 3 Watch 45mm Battery Life

Hello everyone, I have a quick question please. I am trying to decide between Pixel 3 Watch 45mm (Wi-Fi) and Huawei GT5 Pro. I am leaning towards Pixel 3, but I am concerned about battery life (GT5 has 7+ days of battery life). Could you please confirm whether I can push through at least 2 days between charging on Pixel 3? When it comes to background tasks, I only care about continuous heart rate monitoring and sleep monitor. I don't need AOD, Google Assistant etc. Thank you very much in advance!
