This is a good article from Steve Lichfield over at All About Symbian. The article talks about the current standard of battery life in mobile phones and discusses whether or not the life provided by some devices is acceptable.
As we are starting to see devices with larger, brighter screens, faster processors and more powerful applications, it is understandable that battery life on such devices will suffer. The point that Steve makes is that one of the fundamental requirements of a mobile device is that a full charge gets you through at least one day. With some of the new devices this is not the case and users have complained about devices dying before they are able to charge it at the end of the day.
Of some of the most recent devices, the battery life of the HTC HD2 has been highlighted as being insufficient. One solution to this is to use and extended battery for the device. HTC have released an official BP E400 battery with a kickstand, which is a very nice product but is experiencing severe manufacturing delay. We can now offer a third party HTC HD2 extended battery, which has also had some production delays but is now in stock. An extended battery is probably the best solution to extend/improve battery life, but we also offer other solutions where possible. These include cradles with a slot to charge a spare battery and emergency/portable charge packs.
We try to offer both official and third party extended batteries for as many products as possible and usually find that the latter are available approximately 4-8 weeks after a product launch.
