I want your phone if it lasts 14 hours while surfing the web. The 15PM may have 14 hours of battery life, but not while continuously surfing the web. Web browsers significantly cut battery time. Sounds like you're telling a tall View attachment 2407045 tale.
Ha ok two things I should have mentioned. I'm bad at math, and that was not continuous.
That was from about 8 am to around 10pm, and it was not of course continuous. It was eight hours of work and then several hours of tv and reading, with Arc open the whole time. M1 Pro 14", started the day with 100% battery. I took a break every time my watch told me to stand up, breaks for food etc when I closed the laptop.
But I would think if Arc was battery hungry, that would have drained faster. I didn't notice any more battery drain than I would expect.
