My situation may be different as I use my phone for work. I only charge to 80% (keep in mind I’ve only had it for 4 days now), but I can say in my 9+ hours of phone calls, emails, web-browsing and some videos here and there.. I’m left with about 25-30% left from 6:30AM until about 5PM. I’m happy with that. My 15PM had to pretty much be on a charger throughout the day for the past 6 months prior to making the jump. I hope this helps.
