Three days sounds awesome, but is it realistic?

Miami-based smartphone maker Blu, known -- like so many companies these days -- for producing cheap phones with solid specs, has a new phone out, and it promises something that all smartphone owners crave: decent battery life.

The Blu Energy XL is a 6-inch Android smartphone with a 5,000mAh battery which, while not unheard of (Acer Liquid Zest Plus has one, for example, and the Oukitel K10000 has an insane 10,000mAh battery), is definitely one of the larger batteries we've seen.

A quick comparison to popular phones of today: The iPhone 6S Plus has a 2,750 mAh battery, the Samsung Galaxy S7 Edge has a 3,600mAh battery and Huawei's Mate 8 has a 4,000mAh battery.

But Blu has gone one step beyond even Acer, who promises two days of battery life for the Liquid Zest Plus. The company claims the Blu Energy XL's battery lasts 30 days of stand-by, or up to three days of standard usage.

Three days of usage sounds like a fairy tale in a world where most smartphones don't even last a day. And without testing the Energy XL, we can't really say whether Blu's claims are true or not, but we have an educated guess.

The phone sports a MediaTek MT6753 octa-core chip, which can't compare with top smartphone chips of today but it's not as power-hungry, either. But the phone's screen is a 1,920x1,080 pixel AMOLED -- hardly the best option if you want to conserve power. With AMOLED screens, having a dark theme and background conserves energy, so with some optimizations, we can imagine the Blu Energy XL will have a really solid battery life, but three full days still sounds like a stretch.

The rest of the specs are in line with other top smartphones today: 3GB of RAM, 64GB of internal memory, a 13-megapixel rear camera and a 5-megapixel selfie-cam.

Here's the other piece of good news: The phone costs $299, unlocked. Unless you must have the phone with the latest and the fastest processor out there, it's a pretty good deal, even without the outrageous battery life claims.

The Blu Energy XL is available exclusively on Amazon, in silver and gold.
