I have had an iPad mini for about three weeks now and I have a very subjective feeling its battery life is very disappointing. I'm trying to rationalize and refute this subjective feeling, but with no success so far. I switched to the mini from a 3rd Gen iPad which is notoriously the most battery-hungry and it seems the mini lasts much less with doing exactly the same tasks I always do on an iPad - web, email, facebook, music in the background, and occasional gaming. I know that 3D games drain the battery really fast but to me it seems as if the battery drained as quickly when performing "standard" tasks. I also mostly use 100% screen brightness in daylight, and although I realize that that drains the battery a lot, I did the same on the Retina iPad and it lasted much longer still. Today I started using the iPad just before 11 o'clock, now it's 2 PM where I'm located and the battery is at 40% (100% brightness, using just Music, Safari, Mail, WiFi only). Is it normal? Is there an objective test that I can do with the iPad and compare the battery performance with some sort of a reference? I have been searching for something like that but to no avail. I'll be very thankful for any help and comments.
