Some mobile phones can play songs in MP3 format. Some allow you to take pictures and store them. Some allow you to communicate with other mobile phones via Bluetooth. Some allow you to access the Internet. Some allow you to do all this and more. Technology can be amazing.
So, why don’t phones tell you when you need to recharge their batteries? I know you can see the indicator on the handset, but I don’t think people pay too much attention to it. Plus, if they’re putting all these fancy technologies into a phone, how about a battery alarm which tells you a day before, Hey, I’m scheduled to run out of juice, plug me in, so that you know that you can remember to charge your phone.
While we’re talking fancy-shmancy stuff, how about a smart phone that tracks how much you use your phone and then estimates how long your battery will last? I think the smart people who make mobile phones can come up with an algorithm for that.
Information about many hours of battery you have left would be so much more useful than the current indicators of battery status. I wonder if there are any mobile phones out there which show this kind of information.
