We are all tickled that Apple has certain procedures for testing their batteries and their TINY little screen can go for 6-7 hours. My life is complete knowing this...on an Android forum.
How does Apple judge normal use I wonder? My aunt uses her iphone then puts it away. She certainly doesn't use it for 6-7 hours straight. I guess those people are wealthy and bored, or unemployed.
See, this is what normal people do. They don't count their screen time in hours and minutes. They use their phone, charge it, use their phone, charge it. I haven't had above a 35% charge in three days because I toss it on a charger until I need it and leave. Just like I don't top off my gas tank, I also don't do the same with my phone. I don't know anyone who uses their phone and refuses to charge it until its dead. They charge it when they go to bed, or they do not need it. They see it needs some topping off, they toss it on a car charger, etc. If a phone makes it until you go to bed...who cares if the screen stays on for 2 hours, or 20? If you have a need for 4 hours of screen time a day...consider a hobby. Or a job.
