The main weakness of most smartphones are short battery life because a smartphone needs more power to run its fast processor compared to feature phone. Therefore, some manufacturers try to increase battery life by optimizing the phone and offering high capacity battery.
A new smartphone from Philips called Xenium W8510 is claimed to provide up to 35 days of stand-by time. The battery can survive up to 18 hours for talking in 3G mode and up to 14 hours for browsing via WiFi.
The battery capacity is 3,330 mAh – it’s very big for a smartphone, but not the biggest. Interestingly, the battery charging process is very fast. If you charge the battery for 10 minutes, it can stand-by up to 20 hours or 2 hours of talk time. Charging for 30 minutes gives you up to 57 hours of standby time.
Philips Xenium W8510 has a 4.7-inch display with HD 720p resolution. No information about other specifications of this handset.
