After a far too long period of time in which smartphone manufacturers have looked unwilling or unable (or in some cases both) to make any compelling advancements in the battery life department, things are at long last moving in the right direction.

changhong z9 How big is big enough? Changhong Z9 smartphone packs 5,000 mAh battery

Philips has very recently unveiled a smartphone claimed to last up to 35 days on a single charge, Lenovo has announced a P780 with a 4,000 mAh battery, the upcoming Oppo Find 7 might sport an equally as hefty ticker and now we’re hearing word of a handheld with a… wait for it… 5,000 mAh battery.

Yep, you read that correctly. It’s 5,000 mAh, so almost double the Samsung Galaxy S4. Where exactly does that put the real-life autonomy of the Changhong Z9? No idea, but we should be looking at close to 30 hours of talk time. Maybe even more.

After all, the biggest battery munchers are usually the display and processor and in this case they really shouldn’t need too much juice to work as the former boasts a modest 720p resolution, while the latter is a quad-core 1.2 GHz MediaTek MT6589 unit.

Not to be a party pooper or anything, but the meager panel and CPU make the Changhong Z9 an above average phone from basically every standpoint aside from battery life. Plus, there’s only an 8 MP camera slapped on the big guy’s back.

On the bright side, the Z9 is huge, with its display measuring 5.5 inches in diagonal, and it also runs Android 4.2 Jelly Bean. Furthermore, some sources claim it measures a record-breaking (considering) 9 mm in thickness, though if you ask me such a wasp waist is impossible to achieve with a 5,000 mAh battery.

Oh, well, only time will tell if all of the above mentioned details are legit, with the Changhong Z9 expected to be officially unveiled in a matter of weeks. Anyone thinking of jumping on a plane to China once this goes official?
