Today’s smartphones might be powerful beasts, but they are also energy hogs. Even some of the longest-lived Android smartphones only manage around 12 – 15 hours of talk time, and less than 15 days stand-by on a single charge.

That’s probably enough for most users, but what if you are looking for something that lasts even longer? Enter the Philips Xenium W8510, a mid-range smartphone with a mega-sized 3,300 mAh battery.

Thanks to its massive battery, the Philips Xenium W8510 manages to provide 18 hours of talk time over 3G, 14-hours web-browsing time over Wi-Fi and roughly 35 days stand-by time.


While battery power seems to be the biggest focus here, it appears that the phone also will feature a 4.7-inch 720p display, a 1.2GHz MediaTek quad-core processor and 1GB RAM. Not much else is known about the hardware, though we can tell you that the W8510 features fast-charging.

Reportedly, the fast-charge functionality will allow you to charge your dead handset for only ten minutes and yet you’ll already have enough energy to make a 2 hour call or handle 20 hours of stand-by time.

The Philips Xenium W8510 might not have the most impressive hardware specs, but it’s hard not to be at least a little impressed by its battery life and fast-charging capabilities.

Unfortunately, the handset will probably never make its way outside of Japan, which is a damn shame. If the Xenium W8510 ever came to your local market, would you consider it – or would you rather sacrifice a little battery life for beefier specs?
