This morning will be a good test. Run to the gym, listening to music all the way, tracking sets and reps, it usually takes a good 20-30% out of my Pixel 4, so we'll see how the 5 copes now.
Battery definitely seems better after the reset. Things got disrupted yesterday and my routine had to change, so I didn't get a good comparison, but I think my jog to the gym and then home was around 18%, so much better.
I feel like yesterday I finally got battery life a bit closer to what some of you are getting. Yesterday morning was probably tougher for the phone than a usual gym trip. I spent 20 minutes on Zwift cycling (screen on) and then jogged 10 minutes to the gym, 45 minute work out, walk home, 20 minutes watching TV waiting for a haircut, then home. Almost all of this (aside actually having my hair cut) included streaming music or podcasts to Pixel Buds. With Zwift and the TV I would say it was a lot tougher than a normal gym morning, but I had 85% left after all of this. I'm reasonably sure my Pixel 4 would have been down below 50% and needing a charge before I went to work.
End of the day, 16hrs 30 off charge, SoT 3hrs 8 mins (I'm usually between 1hr and 1:30) still 22% left as I went to bed. Easily the heaviest day I would throw at it and it lasted just fine.
