Please read this site: The high-power lithium-ion [FONT=Verdana, Arial, Helvetica, sans-serif]Do not discharge lithium-ion too deeply. Instead, charge it frequently. Lithium-ion does not have memory problems like nickel-cadmium batteries. No deep discharges are needed for conditioning.[/FONT] I know once the battery bashing starts there will be 1000 suggestions to deep cycle batteries. Android may benefit from a discharge cycle, but I can't find anything authoritative on this yet. Perhaps a developer can help?
