Re: How much does the iPhone 7 battery approximately last?
For me iPhone 7 is a phone for whole day use with comfortable margin. But I don't play games much - around 20-30 minutes of puzzle games + few rounds of online scrabble. I have two e-mail accounts with 15 minutes checking interval, essential apps like FB, WhatsApp, ... which consume some battery, take few photos ... At the end of the day I have around 30-40% battery left, so I have no problem to call a taxi or get a SMS ticket for a bus or a train when I'm coming late night home.
For a comparison, I had Lumia 950 and it was able to survive busy day till a midnight with difficulties. On the other hand, Lumia has quick charge so I could charge another 50% of battery within 20 minutes quick stay at home.
