The Axim X50v

replacement battery space is Volt 3.7 V, Capacity 1100 mAh, Weight 25 g, Color Black,

Length 51.58x36.95x6.52 mm ,Type Li-ion , exacted a price in performance. Because of the

need to reserve power, users were getting less than the full capacity of their batteries.

When the battery meter hit 0%, the battery still contained 15%, 25%, maybe even 50% of its

original charge, kept away from the user to feed the RAM.  this would allow someone to

go all weekend with a dead battery, then charge up again when they had the opportunity,

without losing their data.

To give an accurate picture of the X51v's battery life, and how it differs from the X50v, I've put together a table comparing

scores of both the X50v

and X51v, on both standard and extended batteries, as well as the X51v's primary

competitor, the iPaq hx4700. In all wireless tests, both Bluetooth and WiFi were active

until the device shut down. Processor tests simulate playing of a high-bitrate, DVD quality

video. Battery tests with the 2200 mAh extended battery resulted in just over 2x the

runtime of the 1100 mAh batteries in each permutation.

According to Dell's official briefing on the X51, the increase in battery life should be around 15% over the

same model X50. I found it to be higher in most scenarios, around a 25% improvement over a

similarly equpped X50v. This is quite impressive given that the battery capacity hasn't

changed in the least. While it's still not the longest lived model on the market, the X51v goes a long way

towards eliminating battery life as a negative of VGA devices.The Sale Prcie is
