Getting the most battery life from portable systems

Run time of portable systems is increasingly important as devices
become more feature-rich with power-hungry processors, transmitters,
receivers, and media playback, to name just a few. Using a battery
"fuel gauge" is the natural step to increasing run time of the system.
Unfortunately, previous-generation gauges are up to 15% inaccurate,
depending on usage profiles and cell aging. This article describes a
third-generation technology from Texas Instruments (TI) called
Impedance Track, which can provide up to 99% accuracy for the entire
lifetime of the battery pack and extend its life.

Hello,
Using the mobiles which can be charged by USB, they can be charged by portable systems. So that no problem occurs even if there is no charger for mobile. we can charge them by using USB so that we can use our mobile phone. And we can get the mobile charged enough by using portable systems connected with USB.
