It’s a very simple task to go out and buy a high-performance Android smarpthone, but one which has enough battery to last a few days? Not so easy, well before the Philips Xenium that is.
The Philips Xenium W8510 has a 3300mAh battery, and 4.7-inch display not much else is known yet, but we do have some amazing battery life figures. According to Philips this phone is capable of 35 days of standby time or 14
days hours of continuous web browsing! Whats more if you charge the battery from 0% for just 10 minutes it will provide up to 20 hours of talk time!
We’re guessing with this type of battery performance we could be looking at a slower MT6589M quad-core or possibly even one of the new breed dual-core Medatek chips! Still with this much standby time the Xenium W8510 could make a great back up handset if the price is right!Source ]
