.has anyone noticed that if they take their axim out for a few senconds it goes down to 99% then takes 1/2 hour to charge upto 100% again eventhough its only taken say 1/2 hour to charge 40% of it?

Here's some LiIon Battery Information:

All Consumer LiIon batteries (other than coin-type) have circuitry in the battery itself, to prevent overcharging under any circumstances.

LiIon batteries are actually quite dangerous commodities and the only way they were allowed into the Consumer market was to include this circuitry.

Quote:

From First Link: The charge cannot be terminated on a voltage (Which is what the Axim's green light is indicating). The capacity reached at 4.2 Volts per cell is only 40 to 70% of full capacity. For this reason you need to continue to charge until the current drops, and to terminate on the low current. (Which is what the Battery's Sensing Circuitry is sensing, and then doing). It is important to note that trickle charging is not acceptable for lithium batteries. The Li-ion chemistry cannot accept an overcharge without causing damage to the cell, possibly plating out lithium metal and becoming hazardous.

I dunno. I am not sure if it is normal to take 1/2 hour to charge from 99% to 100%. It takes less time to charge my X5 from 60% to 100%.

neonkoala, have you tried different power management settings? Start > Settings > Systems > Power > Advanced. Try select "Turn off device if not used for x minutes" on battery. It should give you longer battery power.
