We have no way to confirm the claim, nevertheless the LionKing800 boasts a remarkable 365 days standby or 3-5 days talk. The source of that power is a 16,800mAh lithium battery -- that's about 10x the juice of a standard cellphone battery. This would be great even for a laptop, even if it could be shrinked to such a small size.
As to the rest of the specs, the GSM900 / DCS1800 dual-SIM phone costs $145 and packs a 3.5", 320 x 240 pixel display, 256MB of microSD memory, Bluetooth 2.0, 4 speakers, eBook reader, music player and a pair of rear and front-facing cameras into a 120 x 65 x 20-mm, N95ish shell.
