Ulefone Power 5: the biggest smartphone battery of the world

Ulefone created quite a buzz this year when the smartphone manufacturer presented its new flagship, the Ulefone T2 Pro. Their newest device, however, probably sets a new world record. The Ulefone Power 5 will be equipped with a 13.000 mAh battery, which is the biggest smartphone battery right now.

Ulefone Power 5 Smartphone

Ulefone Power 5? Did they forget something? Not quite. The Ulefone Power 3 was the latest Power device by Ulefone, which already convinced us with a good battery life. Ulefone apparently skips one generation because after the Power 3 they directly release the Ulefone Power 5. That being said, there won’t be an Ulefone Power 4. That may be due to the fact, that the number 4 represents bad luck in China. We have seen a similar decision from OnePlus, because they didn’t release a OnePlus 4 either. Originally, Ulefone wanted to name this device “Ulefone Power 3 Max”.

Ulefone Power 5: Blackview lookalike

The manufacturer Ulefone wants to go into antother direction with their newest smartphone. On the first glance, the Ulefone Power 5 shows a bigger resemblance to the outdoor-smartphones by Blackview than to the previous Ulefone smartphones. The main reason for that resemblance is the mix between metal and plastic elements in the outward appearance. The metal parts mostly sit on the sides and on the back, near the camera. However, the majority of the backside consists of plastic and rubber material. Looking at the first concept photo, one can see that there is a dual camera on the rear side. The fingerprint reader is on the right side, similar to the Blackview BV8000 Pro, which we already reviewed.

The majority of the frontside consists of the 6 inch display. Of course it works with an 18:9 aspect ratio, which became kind of standard in the last months. We appreciate that Ulefone uses an IPS display with a Full HD+ resolution. That means we get crispy 2160 x 1080 pixels.

The biggest smartphone-battery right now

In contrast to the predecessor, the Ulefone Power 5 comes with a battery twice as big as the Power 3. The capacity is 13.000 mAh, the third generation just had a 6.080 mAh battery. That means that the new Power model takes the pole-position from the Doogee BL12000. Because of safety issues, the 13.000 mAh are divided into two batteries. Interestingly enough, Ulefone claims the Power 5 has a one-week runtime because of this big battery! This means you would only have to charge this phone once a week! This, however, will need at least 2 hours and 30 minutes because of the 5V 5A fast charge technology.

Ulefone Power 5 wireless charging

Another pretty cool feature is the possibility to charge the Ulefone Power 5 wirelessly. Taking into consideration that the battery is huge and the wireless charging just supports 10 W output, a full charge will take some time.

Ulefone Power 5 with Helio P23 CPU

It is not enough to just put a big battery in a phone and hope it will turn out with a nice battery life. Therefore the right choice in terms of CPU is critical. Ulefone sticks with MediaTek and uses the MediaTek Helio P23 processor. This SoC is quite popular among outdoor- and battery-smartphones because it is very efficient. Even its predecessor, the Ulefone Power 3, uses this CPU. Furthermore the Power 5 comes with 6 GB of RAM and 64 GB internal storage.

Ulefone Power 5 Display

Although this device isn’t a camera phone in particular, it of course has cameras – four in total. On the rear one can find a dual camera consisting of a Sony IMX230 20 megapixel sensor with an ƒ/1.8 aperture and optical image stabilization. The secondary camera offers 5 megapixels. The selfie cam combines 8 and 5 megapixels with a ƒ/2.2 aperture. This camera also supports face unlock!

Android’s new operating system

Alongside the big battery there are some further interesting features. Of course there are the several wireless standards that are included. Bluetooth 4.1, 802.11 a/b/g/n Dual Band WiFi, GPS and GLONASS are of course part of the phone. Underneath the fingerprint reader there is a shortcut key. This can be used as a camera button, that will take a picture when pressing it. The second function is voice recording! Furthermore, the Ulefone Power 5 will come with Android 8.1.

Ulefone Power 5 front and rearside

Ulefone has a lot planned for 2018. The release density seems to be quite high this year. Because Ulefone didn’t reveal further technical specifications, we have difficulties to provide an adequate assessment. But until now, the previous Ulefone Power models had very solid processors and delivered a good performance. This is why we are pretty optimistic and expect a well-built smartphone.

    Having only recently purchased the ulefone power 3s a couple of weeks ago and being happy with the phone and its performance I might just be looking to get the power done when our comes out. I do however already plan on buying the t2 pro if it lives up to the expectations. I surely I don’t need all three or do I lol?

      @Ulefone user: You surely don’t need all three 😀 But that’s the fun about gadgets, isn’t it? You always have more than you need! I would probably stick with the T2 Pro, it is very interesting in my opinion 🙂
