It’s my first iphone and i see that it has a verygood battery life, as I’ve used it for 15-16 days and one single charge upto 100% can easily hold till 2complete days, in one charge cycle I’ve watched 6eposids of 30mins each and a movie of 2hr25min. Overall batter is really osm, I didn’t expect this from iphone. I usually keep the power between 30% to 80% and this holds for 1 to 1(1/2) in a decent use of continuous screen time about 5 to 6hrs smoothly. Well battery is good..
Obviously with appleA15 chipset it’s really soo smooth, overall having a 60hz display while all ther brand are running with 120hz display. But still i say it is smooth to a good decent level.
