Barely getting 3 hours SOT on a full charge (P7)

It might be placebo but after the June update my battery life has been struggling. I'm pretty sure I'm not doing anything different but I'm open for suggestions.

I did get a battery replacement because the entire back panel on my phone was replaced but I doubt that could be the issue since my battery health is literally at 100%.

What's the average SOT P7 users are getting these days? I can't imagine even 5 hours of SOT can count as "all-day battery". For reference I'm using LTE with my brightness around 50% most of the time.
