Re: Just curious
Not sure you can put any meaningful figure on "runtime" because people use phones in so many different ways that affect consumption. Using a phone mainly to check emails and make & receive a few calls and SMS messages is completely different to using it to watch Netflix, YouTube and be on social media for half the day. If you use the cellular connection significantly, then how close you are to the cell tower makes a huge difference to the power consumption.
I put my phone on charge when I go to bed and unplug it when I get up. I do not want to have to charge it in between. Therefore I want a phone that has a runtime of 16 hours at least with the way I use my phone 99% of the time.
