The Ulefone Power is the first smartphone to have a giant battery that also has a sturdy middle-class hardware and an attractive design. Apart from a 6050mAh battery the phone offers a 5.5-inch fullHD display, an octa core processor, 3GB RAM and a fingerprint sensor. Whether or not the Ulefone Power’s name says it all, we are going to find out in this review.

Ordering the Ulefone Power & scope of delivery

Ulefone Power LieferumfangWe got our device by The Ulefone Power can be ordered there for 172$ from China. Apart from the charging adapter (2A, quick charge adapter) and the USB cable there were included a silicone cover, an OTG cable as well as earphones. Additional accessories as for example a leather cover can be found at!

Processing and design

The Ulefone Power weighs 197g and is 10mm thick. You can choose between the colors black, white and wood. The back of our white version is laminated and resistant to fingerprints and dirt. The fingerprint sensor is located at the phone’s back and worked perfectly fine in our test. 8/10 tries unlocked the Ulefone Power without a fault report. After applying your finger, the system is displayed instantly. Although smartphones as the Redmi Note 3 or the Meizu Pro 5 unlock even faster the Ulefone Power’s unlocking time is still perfectly sufficient.

On the phone’s right side you find the power button and the volume keys as well as a camera button. The camera button is placed – for whatever reason – very unsuitably in the middle, however for portrait pictures this fits perfectly. The keys fit neatly in the body with only little wiggle room. The aluminum frame houses also the SIM slot (2*micro or 1*micro and micro SD up to 64GB) and the infrared sensor.

On the front there is a notification LED with three colors and the dimly lit soft touch buttons. In daylight the illumination is invisible which however is not necessary! The bezel is rather wide with 4mm. Those who were expecting a filigree and handy smartphone will be disappointed with the Ulefone Power. The battery power can be noticed in the dimensions. The Ulefone Power is obviously bigger than most of the 5.5-inch phones. In conclusion you get a robust and neatly processed smartphone with an optionally wooden back (rear cover can’t be exchanged).

The feel is – at least in our version – not extraordinary, but in comparison with other smartphones that house a monster battery it is okay. The Ulefone Power’s specials are still to be expected.


The 5.5-inch LTPS display has a 1920*1080 pixels resolution. Everything is displayed razor sharp with a pixel density of 401 pixels per inch. No matter from which angle you look at the phone the colors stay the same. Color representation and contrast are really great with default settings. Unfortunately at the moment there is no MiraVision in the system for readjusting. We hope that Ulefone will supply this useful tool in their next update. The display is very bright with 575cd/m2 in average, at the top however it is a bit brighter than at the bottom. In practice you don’t see the difference and readability in direct sunlight is well, depending on the angle, however, the display reflects very much.

Ulefone Power Display Tocuhscreen 5-PunktThe multi touch display registers up to 5 touches at the same time and reacts very fast and precisely. The Ulefone Power is protected from scratches by Gorilla glass 3 and the glass is nicely curved at the edges for a smooth touch (2,5D glass). Ulefone presents with the Power an all in all nice and flawless display.


Phones with a huge battery are part of every Chinese manufacturer’s selection. However, mostly they only use a slow quad core processor. The Ulefone Power sets a good example and uses a MediaTek MT6753 octa core. Unfortunately the system does not use the 64-bit architecture, yet. Here we have to wait for an update. However this has no influence on the smartphones speed. The Ulefone Power navigates fast and smoothly through the system without any noticeable interference.

Ulefone Power Antutu Benchmark Ulefone Power Geekbench 3 Ulefone Power 3D Mark (1)

Ulefone Power AndrobenchWith the 3GB RAM multitasking is absolutely no problem even with multiple Apps running in the background. The most graphics-demanding 3D games don’t always run a 100% smoothly but can be played well. The game having the most troubles was Asphalt 8 that could not be played at all, even with low graphic settings. Other 3D games as Nova 3 or Modern Combat 5 ran pretty well with only little lags. Heat development is average with 50° to the max. Those who want a pure gaming phone should better choose a Helio X10 or Snapdragon processor. In terms of battery life and performance combined, the Ulefone Power is at the top of the battery ranking at the moment!



Ulefone installed on the Power an unchanged and clean Android 5.1 system. Even an update to Android 6 Marshmallow will be accessible. The system runs reliably and the launcher has the stock Android looks.

In the options menu you find additional options for the notification LED’s color, SmartWake gestures and gestures for the proximity sensor. Multiple fingerprints can be taken into storage and even single Apps can be blocked.

Ulefone Power System Andorid 6Apart from that only the usual Google Apps are preinstalled as well as an additional launcher (ULauncher) that can be activated as needed. Those who want a clean and almost unchanged Android system have the perfect phone with the Ulefone Power. Of course the Playstore is preinstalled. Updates are received directly via OTA on the smartphone.


Ulefone talks about a 13 megapixel Sony IMX214 Sensor with an f/1.8 aperture. As a selfie cam they use an Omnivision OV5648 sensor. The rear camera is perfectly suited for occasional snapshots; however, you should not expect a replacement for a camera. The color representation is a bit too cold and even in good light the pictures are a bit blurred. Close-ups are in good quality. The autofocus works fast and the shutter speed is good.

The double-LED flash on the phone’s back is extraordinarily bright and works perfectly together with the camera software. The front camera serves for selfies and video calls, however the images are not overly well. You can find smartphones within this price range that take better pictures. Above all, the recent Cubot devices (X16/X17) are to be mentioned.


Ulefone Power Empfang und NetzThe Ulefone Power’s reception is above-average good. Even at places where I usually don’t have reception I was still able to phone someone. Both SIM slots can use LTE internet, but not at the same time.

Calling quality is also good and the voices are transmitted in a clear way. I was able to understand the callers perfectly in a pleasing volume and with a slightly tinny sound. The proximity sensor works great during the call. The internal speaker is average and starts to make noise at high volume. You shouldn’t be expecting a very well defined sound; for notifications, ringtones and talking hands-free it is absolutely okay. Via the audio jack you get great sound quality with middle-class headphones.

Ulefone Power Sensoren SensorboxHere the Ulefone Power surprised us. Next to the 3 usual sensors (proximity, light and direction) Ulefone has built in an infrared sensor and an electronic compass. Even OTG is supported and worked perfectly in the test. The IR sensor works with every remote-App accessible in the Playstore and I was able to operate our Sony TV without any problems.


The WLAN module transmits in the 2.4GHz net with n-standard. 5GHz is not supported. The reach is above average and the signal was constant with a quick connection.
Ulefone Power GPS Test Fix (1)The compass worked well together with the GPS, however it had to be recalibrated every once in a while. During pedestrian navigation I always knew in which direction I was heading. The navigation in the car was also great. During the 100km test route there were absolutely no problems and all of the instructions were at the right time (Google Maps navigation).

Even in terms of connectivity Ulefone stands out of the competitors with additional sensors and awesome WLAN reception.


Ulefone Power Battery BecnhmarkThe Ulefone Power houses a firmly attached 6000mAh battery. The charging adapter that was included in the delivery takes 2 hours and 10 minutes to charge from 0 to 100% and 5913mA were transmitted in the Ulefone Power. These are very good values. At normal use 3-4 days are not a problem even with power-consuming Apps. The Power offers twice as much battery time as a normal middle-class Smartphone. Even extreme power-users can make it through 2 days with the battery-phone. If you set your display to mid-brightness (300cd/m2) the Ulefone Power makes it for 12 hours and 42 minutes trough the Geekbench 3 Battery Benchmark. With 4830 points the Power is one of the best smartphones out there.

82% Battery-monster

The Ulefone Power aces the mandatory parts. The good processing with optional wood optics, the very good reception with all LTE bands, the high reach of Wi-Fi, the good fullHD display, the clean system and the enormous battery life are a clear plus for the Ulefone Power. Also the Power’s speed is noticeably higher than the competitors’ battery-phones. A negative part is the camera, which in fact isn’t too bad at all. A 6000mAh battery doesn’t fit in a filigree shell and is not exchangeable; this might be a bit annoying. With 197g the Ulefone Power is also not a lightweight. All in all Ulefone raises the bar and makes it to the top of the battery-ranking. The phone convinces in the test and we give you a clear buying recommendation.
