Review: uleFone Power

Note: This review is imported from our former blog: Ulefans.com

More than a year ago after the release of the Be Pro and we have seen uleFone grown in their smartphone development and we see it back in one of their latest smartphones: the uleFone Power, which is provided for review by our eshop partner: CECT-SHOP.com.


The uleFone Power comes with a box full of accessories. Next to the phone itself you will find an USB cable for data and charging, headphones, manual, a traypin to get the simtray out of your phone, a wall plug and a USB OTG cable. Next to the standard package items CECT-SHOP also added two smartphone stands to it and a handwritten checklist of the package contains and a technical test. A service we haven’t seen before with other eshops.

Build and Design

The first thing we noticed about the uleFone Power is the weight. The uleFone Power has a weight of 190 grams, the cause of this weight is the 6050mAh inside. Yes, the Power seems to be heavy but the weight gives the smartphone also a premium and solid feeling. The uleFone Power has a thickness of 9.5mm and has due to it’s 5.5 inch display a size of just below an iPhone 6 Plus.

The uleFone Power is build out of metal and glass which favors the build quality. We have received the white version of CECT-SHOP.com and it just looks stunning in our opinion. For us it’s the first white version of a smartphone and now we know why people want a white one. The Power feels good to hold.

On the front we find next to the 5.5 inch display, the earspeaker, front facing camera and the proximity and ambient light sensors above. Below the display, you have 3 backlit capacitive buttons. On the back, you have a 13MP Sony IMX214 camera, dual-LED flash and the fingerprint sensor. Also the loudspeaker is placed on the back.
At the top there is a 3.5mm audio jack port and an IR blaster, while on the bottom you will find the microUSB port and the microphone.

On the right side, you will find the volume buttons, power button and a camera shutter button while you find on the left side a Hybrid SIM slot. This means you can choose to use the Power with two microsim cards (dualsim) or one microSIM and a microSD card.

Powerful specifications or…

The first thing you notice next to the size and weight is the 5.5 inch 1080P Full HD display which has 2.5D Gorilla Glass 3 for protection. UleFone also delivers the Power with a pre-fitted screen protector. Unfortunately ours came with a small dust bubble under it, but it’s a good service to the phone owners. The viewing angles of the display are good, as also the colors. Although the display is a little bit reflective, the brightness during direct sunlight is good. With Miracast installed you can even adjust the screen colors and contrast to your needs.

The 3 capacitive keys below the display are backlighted, but are dimmed to much in our opinion. You only see the difference of the buttons when you are operating in the dark. The Power also have a notificati is very dim and unless you’re in a dark environment, you don’t really see the difference. The light and proximity sensors responded good during our test. A notification LED next to these sensors can glow in red, blue or green and can be customized.

A feature we see a lot nowadays is the fingerprint sensor. The sensor can be used for unlocking your phone. Buildin software gives you the opportunity to give extra commands during fingerprint usage. The sensor is quick and accurate.


The Power comes with pre-installed Android 5.1 and uleFone has announced an upgrade to Android 6.0. The software is similar to stock Android although uleFone has customized some small things. For example there is no app drawer anymore and the u-launcher is included. CECT-SHOP pre-configured the Power in the German language because of its main focus on the German market. Of course CECT-SHOP sends out worldwide and the language can be changed easily.

The Power has an octa-core MT6753 64-bit processor by Mediatek, a Mali T720 GPU and 3GB of RAM. The operation of the Power is smoothly, but it’s certainly not a winner for playing heavier games. HD video playback and running some games are no problem for the Power and is not getting warm. You can see the performance back in the Antutu score of 37394. The score of just above 37000 is pretty good for this processor.

The Power has out of the box 16GB of storage which can be expanded to 128GB by MicroSD. The MicroSD can be set up as the default write disk. Please note, when you insert the MicroSD card the dual SIM functionality is not possible anymore because uleFone has chosen for a hybrid solution of the sim-tray. The Power also supports USB OTG for HDD or USB drives.

Connectivity and audio

The Power supports dual SIM (micro SIM) and 4G LTE (800/900/1800/2100/2600 band20,band3,band1,band7,band8 supported) and has a great reception. Although you can place two SIM cards, only one sim can support 4G when you are using 2 sim cards. The call quality is pretty good of the Power. The earspeaker has a clear sound, while the microphone does the job for a clear sound for the other side. The device supports Wi-Fi 802.11 b/g/n and Bluetooth 4.0. Both are having no connectivity problems in our setup and the WiFi reception scores very well. The GPS got a fast fix and is very accurate. A bonus is the infrared transmitter which can be used to control your home devices. This also worked flawless with our Philips TV and motorola setup-box.

When using the Power as your music companion on the road we found out that the audio quality is okay, but it sounds so plain. It is missing bass in our opinion. Also the volume through the headset can be adjusted in a higher volume too in our opinion. The speaker itself is okay, but can sound distorted when going to the maximum in volume.


The uleFone Power features a 13 Megapixel rearcamera with a Sony IMX214 sensor. The sensor as a f1.8 aperture and a dual LED flash on the back makes it possible to take your pictures in low light circumstances. The Sony sensor has been used in the past by uleFone and wasn’t always configured very well. For the Power the sensor is configured better. It even surprised us, the image quality is pretty good although the focus isn’t always accurate and in bright light the optimisation of the camera can’t always handle the brightness which makes the photos sometimes blurry in the corners. We expect that this will be solved in a future update. In our opinion the best photos are taken during sunny days, the colors are natural and the photo are detailed. Pictures taken from a short distance are handled well and are detailed when the focus is good. Not bad for a €169,99/ $189.41 smartphone.
When taking pictures during low-light circumstances can be better in our opinion. We took some pictures outside (without flash) and we missing the warm colors of for example the streetlights and we have some (expected) grain. Nearby pictures in the dark are okay thanks to the f1.8 aperture and the powerful dual LED flash.

The Power can record videos at 1080P but are for some reason of poor quality. Hopefully uleFone can fix this in a next firmware release.

The front camera for selfies is 5 Megapixel camera by Omnivision. The camera shoots some good photos in detail and is a good companion for your selfies.

Okay, but how about the battery?

The keyfeature of the Power is the battery. With a massive Sony 6050mAh battery inside uleFone claims to have a solution for the smartphone users who are complaining of no battery during the day. It seems like uleFone has done the job well and optimized everything with a good battery life in focus. We used the Power with a daily used pattern (wifi, calling, 3G etc) after one charge and the Power lasted for around 47 hours with, Pretty impressive. The Power package also included a USB OTG cable which makes it also possible to charge another smartphone with the Power.


The Ulefone Power is a great phone for it’s money. Okay it’s not perfect, for example the speaker quality in high volume and the low-light/video results that did not impress. The performance impressed us for the used chipset and although the camera isn’t at it’s best in low-light, the photos during daytime are very good and can get even better after some software improvement by uleFone. The building quality, it’s design and battery life makes it a must buy for everyone who likes a 5.5 inch phone with a good display, 4G LTE capabilities and the fingerprintsensor. The uleFone Power is available for €169,99/ $189.41 at CECT-SHOP.com.
