Hello, After noticing a significant drop in performance, I took the plunge and upgraded my iPod 3G's battery from the one that was shipped to one manufactured by NewerTech. The thing is I want to ensure that this battery performs better than the previous one. As such, can anyone tell me the best way to charge a Lithium Polymer battery? Is it better to charge it as frequently as possible, or to let it run down between charges? Any help greatly appreciated. Stuart.
