【Watch The Butcher, the Chef, and the Swordsman Online】

Lots of phones will be Watch The Butcher, the Chef, and the Swordsman Onlineannounced at Mobile World Congress this week -- Samsung's Galaxy S9 is the biggest one -- but none of them come with a battery that could last up to five days on a single charge like the Energizer Power Max P16K Pro.

That's right, the P16K Pro has over five times the battery capacity of the Galaxy S9 or iPhone X.

Some people value processing power, or a larger screen, or a better camera, but I think we can all agree that we want our phones to last longer.

That's where the P16K Pro comes in with its whopping 16,000 mAh battery. By comparison, the Galaxy S9 has a 3,000 mAh battery and the iPhone X has a 2,716 mAh battery.

Both of these phones typically last "all day" and need to be plugged in at night, but not the P16K Pro. Depending on your usage, you might only need to plug it in every five days, according to an Energizer rep. If you use your phone less, you'll see even longer battery life. The company says it'll have up to something like 40 days of standby time.

Of course, the trade-off with a phone with such a massive battery is thickness. As you can see in some of these photos, the P16K Pro is an absolute clunker. It's about twice as thick as an iPhone.

Despite its thick profile, Energizer's still managed to squeeze in some decent specs. The 5.99-inch 18:9 aspect ratio display (full HD resolution) is pretty large and there's dual cameras on the front (16-megapixel + 13-megapixel) and back (13-megapixel + 5-megapixel). There's also a fingerprint sensor on the rear below the cameras.

The phone's powered by a MediaTek Helio P23 and 6GB of RAM. It comes with 128GB of internal storage and has a microSD card slot for expansion. And there's also dual nano SIM card slots for people who like juggling two numbers.

Energizer says the phone will ship with Android 8.0 Oreo. Unfortunately, I didn't get to check out what the software looked liked on the P16K Pro because the unit on display wasn't a working model.

While most people aren't going to be down with doubling their phone thickness for battery life, it's not so bad if you really think about it. People already increase their phone's thickness with bulky cases, which don't add any battery life, or with battery cases that do. People also carry around external batteries that are equally as thick.

If you just consider the battery life, the PK16 Pro sounds like a dream for road warriors or backpackers who venture out into nature where there aren't any outlets.

Energizer says the phone will launch sometime in September for around $500, which is pretty darn affordable.
