Customer Questions & Answers

Customer Reviews

Top Customer Reviews

Color: WHITE
• Who I am: I'm not a shopping lover, I am not a tech geek, but like most of you I hate spending so much money on overrated Samsung or Apple iPhones and hate contracts with network providers.

• What I got to say about Studio Energy 2 by BLU: I Absolutely recommend it for yourself or as a gift to someone who you care, because this phone boasts solid and stable performance, not only it has probably the longest lasting battery in the smartphone market. A comparison: if you consider the battery life of most iPhones and Samsung phones as cheap Windows laptop battery life, this phone has the battery life and efficiency of newest Apple Macbook Air.

• Who I "do not" recommend this phone to: Gaming lovers, 3D gamers, hardcore app developers, those who cannot put up with phones with unknown brand images

• Who I DO recommend this phone to: people who care about having a phone that does not die; who travel a lot, sometimes internationally; who put the importance of using a phone for work, studying, communication, productivity improvement; who use pretty reasonable Android apps; who watch a lot of videos and play games that do not require top-notch hardware specs.

• What do I think about this product in 1 sentence: "This smartphone is a beast, but it has things it can do and it can't. In my case I needed a phone that doesn't die even when I go out for a pub crawl with my friends. I needed a phone that does not cage me in to a contact. For fulfilling my needs, Studio Energy 2 has been the best, and it will be."

Overall, this phone is an incredible value. I would absolutely buy it again. For $129, it's a steal. The hype about the battery life is justified, and otherwise it provides a solid Android phone. It's not a flagship, I find myself dreaming of a better camera and wishing for a fingerprint sensor...but everything else is quite good here.

Starting off, I charged this thing to 100% before powering it on. I wanted to do a couple full runs from 100% to near zero. My first charge cycle, I unplugged and then started setting up and updating off the charger. I played around with the phone most of the evening, then used it at work and the next evening. I got over NINE HOURS "Screen On Time" (SOT). If you haven't heard that term, it's really the best indicator of a phone's battery life quality - your screen is on when you use it, so SOT tells you how long you have practical use. Anywho, 9+ hours is incredible. I've had many Android phones, and a few iPhones...this is double anything I've ever experienced. For comparison, recently I've had a Samsung Galaxy S5, Nexus 5, Blackberry Priv, and a Blu Studio C. None of these phones could consistently get above 5 hours SOT, and most sat closer to 3-4 hours SOT. To get 9+ is a dream come true; I've included screenshots with this review. On my second charge cycle now, I've got over 6 hours SOT and 52% left.

Other than the unbeatable battery life, the phone is very solid. I was a little considered it would be too thick given the huge battery, but that is not the case. I've included a four images with this review, for comparison purposes; three of these show the Energy 2 compared to other phones. The leftmost phone is the Energy 2, middle is a Samsung Galaxy S5, and the rightmost is a Blackberry Priv.

I am writing this review to help out those who use Tracfone but would like a better phone than the ones offered on the Tracfone website. I have been a Tracfone customer for several years now and was happy with the service except for the phone was terrible. If you use Tracfone and wonder if this phone is compatible the answer is yes. I will start by saying that I am replacing my ZTE Valet Z665C android phone. First off what you want to do is go to the Tracfone website and order a Micro SimCard (NOT NANO) with taxes and fees it was about $13.07 . Then order this wonderful new Blu Studio Energy 2 from amazon (worst part is that buying from amazon now takes forever if you don't use prime). When you get the phone and sim card delivered you will want to call Tracfone from a landline or other phone (not your cell number). Tell the person you are updating your old Tracfone with a BYOP and it is a GSM phone. Make sure they send you a text showing your minutes and text etc. available in case they lose all your minutes you will have proof. If it takes you less then an hour you did good and by doing it this way you should save time over the process that I went through. After they program your phone you will want them to send you a conformation email so you can be sure you have any further instructions you may need. It may take a couple few hours to transfer your number. Once done you should go to your old phone contacts and click in settings and transfer contacts to SD card (remember the file name). Then you can insert the SD card into your new phone and go to settings click export from SD to phone or Google acct. this should finish setting up your contacts. I am still learning this phone but I can tell you for $179 this is a very sturdy and nice phone upgrade with 4gLTE service. ....WOW on 12.20.Read more ›
