Wow, impressed by the number of people saying, essentially, "I don't care, so you shouldn't either", or whatabouting with everything else going on in the world. We're on a site dedicated to discussing even minor details of Apple products. It is possible to care about other things going on in the world, and also want better information display on your iphone.
The iPhone currently gives the battery level in an analog format, which is good for a very quickly parseable general idea of the level, but which lacks precision. Like an analog watch. They are switching to a format that exclusively uses a digital readout for most of the time - this gives an exact number, but then the brain has to interpret that number to get to a general idea of the level. Like a digital watch. So, why not both?
The examples exhibited in this article show a number of better ways to handle this. When I initially saw the digital display, I saw it with a "100" (or maybe high 80's/90's?) display, with a full battery icon, and assumed the icon would become less full as the battery level lowered, like these suggestions show. I'm a bit dismayed that it appears Apple has completely forsaken the analog display in favor of digital, when that clearly wasn't necessary.
