BLU Studio Energy blows away the competition in our battery benchmark test

BLU Studio Energy blows away the competition in our battery benchmark test
BLU is certainly turning heads of late, especially after announcing a slew of new smartphones not too long ago during CES 2015. We’ve been astounded recently by its mind-boggling thin smartphone in the BLU Vivo Air, which impressively enough also features one killer design with a premium quality attached to it. Getting the chance to check out its latest smartphone, the BLU Studio Energy, it’s clearly not messing around with its monstrous sized 5000 mAh “super” battery.

So far, our battery benchmark test list reveals three smartphones that top the chart – the Motorola DROID Turbo, ZTE ZMAX, and Huawei Ascend Mate 2 4G. Well folks, the BLU Studio Energy triumphs over all those other aforementioned smartphones – catapulting straight to the number one spot. Armed with a 5000 mAh “super” battery, which more than eclipses that of the capacities in the other phones, the BLU Studio Energy is able to reach an awe-inspiring mark of 14 hours and 53 minutes from a full charge.

Seriously, it doesn’t just beat all the other phones, it actually sets the benchmark for everything else. In fact, there’s still a huge gap between it and the second longest lasting smartphone in our list – the Huawei Ascend Mate 2 4G, which taps in at 11 hours and 26 minutes. To be fair, though, the BLU Studio Energy’s incredible longevity can be attributed to 5.0-inch 720 x 1280 IPS display, which wouldn’t require as much juice when compared to those with higher resolution screens. Paired with that Herculean-sized 5000 mAh battery, there’s no wonder why it’s able to last longer than everything else we’ve tested.

The benefit to users of course is obvious, but on the other side of the fence, it takes over 300 minutes for its battery to be fueled back to 100% capacity from a completely depleted stage. To that end, it’s the price you pay for having a phone that deliver outstanding battery life. Ultimately, though, the BLU Studio Energy’s record indicates the trend we’ve been aware for some time now – that larger capacity sized batteries are needed. And would you believe it's selling for $149 outright through Amazon right now? That's a pretty good steal to tell you the truth!

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

Dude, also look at the hardware. A 720P screen?? Seriously?? Z3 Compact is way better with a lower capacity battery. All the other phones in the top list have a FHD/2K screens and snapdragon 801/800 processors.

its not like you're going to get it down to 0% in a day or just charge it while you sleep then

OMG !!! What the f**k do you want for $150? Plug it in before you go to bed and be done with it.

It also helps not having an LTE radio bogging it down either. How hard is it to charge a phone every night before going to bed?

What the hell! Why would this so-called battery champion phone take over 300 minutes to charge up to 100%? I have a phone with a 4,500 mAh battery and it charges from zero to 100% under 90 minutes! The phone lasts me 2 days on a single charge and yet it also charges up to full in no time.

Well, taken into account that the battery will last a significant longer time than even the phone you have, I would bet that you'll very rarely go to bed with anywhere near half the battery depleted. Which puts the charge time under 2 and a half hours. The average person sleeps more than 2 and a half hours, so that gives you ample time to fully charge your phone and the comfort in knowing that should something happen over the course of the next 3 days that prevents you from charging your phone, your device will still be functional when all others (including your current phone) are dead.

Cheaper battery tech doesn't charge as fast. But slow charging prolongs the life of a battery anyways.

Likely has a Mediatek processor and your device has a Qualcomm. Qualcomm has their RapidCharge thing that ramps up the charge rate, which can make charging a higher capacity battery less painful. AFAIK, Mediatek does not have such a feature.

Wow, this monster lasts more than twice as long as Apple's offering. How many days of average usage does this equate to?

Holy smokes! It lasts more than twice than my iphone 6 plus! Insane.

My Droid Turbo gets mediocre battery life, unfortunately. Thinking I have a defective unit, don't know that it can be returned, though.

Blame the resolution.

True, but I mean compared to what I've seen people getting online. Most people seem to get at least 6-7 hours of screen on, I get around 4 with very light / moderate usage.

Well, plug it in before you go to bed. Assuming you sleep more than five hours. Hopefully, you are not sleeping with the device . Otherwise, what you need is, some mental counseling.

Isn't this just a rebranded Gionee?

Of course it's going to rock on battery life. It's specs are really not even mid level. What I don't understand is that if the major OEM would increase just by 1MM in thickness they would be able to add around 1000 mah to their battery's.

Low power processor + Low resolution. Lower resolution will ALWAYS mean better battery life on the same processor vs higher resolution. Been saying this stuff for years and people still don't get it. See Z3 Compact as well.

Ooh, 15hrs+ on screen time should be the new standard lol.

Charging time is not a real issue unless it is more than 6 hours, since people usually charge phones through night when we sleep

For all the guys with the complaints. ITS $150 BRAND NEW WITH NO CONTRACT. Hell, I might eventually pick one of these up for my kid as their emergency phone. Forgot to charge it this week? Still has half a battery!
