Monsters from Asia: The $149 BLU Studio Energy with its insane, 5,000 mAh battery

Established just a few years back in 2009, BLU Products is a Miami-headquartered mobile phone manufacturer, or at least that's the official story. We're not sure, just how much of the available BLU smartphones the company actually makes itself, however, seeing as most of them are re-branded handsets from China. The impressive BLU Studio Energy is one of them, and its story is well worth your time.

Based on the aptly-named Gionee Marathon M3, the Studio Energy has two highly enticing selling points. First, it costs just $149 on Amazon US, and second – it features an insanely large, 5,000 mAh battery that made the phone the absolute record holder in our battery life benchmark as of this writing, with a time of almost fifteen hours. This makes BLU's claim of 96 hours of "standard usage" and 45 days of standby believable, and the inclusion of a special reverse charging cable in the box – logical.

But that's not all there is to the Studio Energy, though admittedly, it is its highlight. Considering its affordable price tag, the rest of the specs don't sound too shabby – we're looking at a 5-inch, 720 x 1280 resolution IPS display with a Gorilla Glass 3 cover, a quad-core MediaTek MT6582 processor, 1GB of RAM, 8 gigs of storage (expandable through microSD), an 8-megapixel rear camera, and a 2-megapixel selfie snapper. The phone is outfitted with the usual connectivity features sans LTE – 3G HSPA support (21 Mbps), Bluetooth 4.0, A-GPS, and even FM radio. The Studio Energy runs a build of Android 4.4 KitKat, but BLU has promised an upgrade to Lollipop down the line.

BLU is not an Asian company, it's an American company. They just rebrand their phones from Chinese manufacturers.

They don't source from multiple Chinese manufacturers. The specifically import Gionee phones. All of their phones are Gionee rebrands.

1GB ram and 1.3Ghz Quad CPU with Mali 400 GPU.... not attractive buy period. minimum mid-end for 2015 is 2GB ram, 2Ghz Quad with Mali 450 GPU, 16GB internal storage.

Then it's not for you. There's many people that would sacrifice speed for insane battery life.

Not all people need a 2gb ram phone. You're not the only consumer in this world.

2GB ram don't drain extra battery life. I don't mind paying a bit more for the RAM. Besides XiaoMi is doing 2GB for the RedMi series and its price is about the same or lower.

Well I would mind paying extra. Like was said, this phone is not for you! It's for me! In fact, i just ordered one off of amazon after reading the article. The phone comes with a phone case and screen protector -INBOX. What other company does that? This phone's selling point is the battery, plain and simple!

I have a BLU Studio Energy, I've owned it for about 5 days now. It's actually an excellent phone. It's my secondary phone to a OnePlus One. The processor performance reminds me of the 2013 Moto X. Infact I sold my old secondary phone a 2013 Moto X in order to buy this phone so the Moto X performance is pretty fresh in my mind. I popped my sim card into the Energy and went around for the past 3 days and it's obviously a little bit slower than my OnePlus One in processor speed and network connection but it's totally livable. I get around a 120 ms ping with a 4 Mbps download speed on AT&T. Build quality is excellent, screen is perfectly fine looking, camera is better than the Moto X it replaced, and the led torch on the back is insanely bright and makes a great flashlight. The battery life is insane, I had it sitting around the house on my day off for 13 hours with the screen off doing a standby test on it and the battery dropped 1%! 1 freaking percent in thirteen hours... Either way, there's more to phone ownership than spec sheets. Try buying one before you run on and on on the internet like a fool.

Yes there is more to a phone than a spec sheet. However, most of the professional and owner reviews on this phone say that it stutters and lags when scrolling or changing apps. Have you experienced this or does your phone scroll smoothly.

25. Doakie

The most stutter I've seen is in the Android settings menu. The stock launcher is pretty horrible and it runs extra slow. I started out using the Google Now launcher then switched to my usual default Nova Launcher. Nova runs glass smooth when flipping between desktops and app lists. The only other hesitation besides the system settings menu is upon hitting an icon on the desktop sometimes it hesitates a second before the app opens, but it's no slower than a 2013 Moto X. In fact it's probably smoother than the 2013 Moto X was. If you want a readily available comparable I'd recommend you grab a 2013 Moto X and try that out and see how smooth it is.

Take a second look at the price please... This phone is focused on endurance, not performance.

Then what's the point of the "Monsters from Asia" thing? BLU is not even from Asia.

We should be used to it by now. PA is fast in delivering the news, accuracy not their primary forte.

Blu is a American company that rebrands and imports Chinese phones. Blu's phones are designed and made by Gionee.

I have used the Indiandian version of this phone, Gionee M3 and the battery life is below average considering the 5000 mAh battery. Even Note 3's battery life is better than this phone's despite the larger screen and much more powerful processor.

11. Doakie

Interesting. That's not my experience at all. The lowest I've seen mine go with a day of heavy use was 52% after 16 hours of usage. I woke up at 10am and went to bed at 2am and it was at 52%.

12. Doakie

And I used to own an AT&T Note 3 which was dead everyday by 3-5pm when I'd wake up around 8am. Currently my OnePlus One is right around 30-40% at 5pm when I get off work and now I tend to wake up around 5:20am. So my OnePlus One trumps the Note 3 in battery performance but it's no where near as long as my Energy. I wish I had more experience with the Huawei Ascend Mate2 4G, I just bought one for my wife two weeks ago but I'm not sure what her battery life experience is. She says it still has a significant amount of battery every night she goes to plug it in, but I'm not sure what percentage that is. If you haven't guessed in our household we've made a switch to more battery heavy phones.

My own Note 3 is a positive experience. End of the day i have about 70% plus or minus. I do an average of an hour web surfing.

You're lucky then. My Note 3 would last until the end of a work day. My wife's Note 3 would last about 5 hours of intermittent use and would be dead. I bought her an Ascend Mate2 4G and now she's happy.

You should have bought the THL 5000 (see Android Authority's review). Much better specs with the same large battery.

It would be really nice for PA to do a full review of this phone. I'm sure its not for me, but it may be something great for my wife. I got her the LG L90 and that thing has been a piece of crap. She's not tech savvy in the least and that phone just has so much crap on it.

Another stupid article, thanks PhoneArena. BLU is not Asian, but American company. Apple pays to Chinese manufacturers to produce iPhone. So does this makes Apple Asian (even Chinese) company as well ?

Apple designs those phones that it then pays the likes of Foxconn and Pegatron to manufacture. Gionee has an ODM-like relationship with BLU. Surely, you must be seeing the difference?

The difference is apparent to anyone with brains. Obviously he doesn't have any.
