Dual-screen, E-Ink showdown: Oukitel U6 VS. Siswoo R9 Darkmoon

They’re big, they have big screens, and they both have two screens – the Oukitel U6 and Siswoo R9 Darkmoon are powerhouses that collide today, only on XiaomiToday.

Let’s see which one is better.

Big screens and quality processors are the standards in today’s smartphone industry, where manufacturers are racing against each other to produce a better, faster, and unique model that will win over the competition and get the status of the best-selling device. In a race for the customers, innovation and quality-to-price ratio always set the market present state. Everyone’s evolving, and everyone tries to win the shoppers by implementing something new, something of higher quality, or something that will customers like.

Today we’re comparing the two similar devices, both of which having a unique feature – a second screen. That is the new commodity to the smartphone users, which was introduced years ago with mobile phones that could open, revealing two separate screens, and others. The second screen on today’s rivals is used as a secondary display, providing black-and-white imagery and text. The readers are targeted with this screen, and people who always need extra juice from the phone – E-Ink display spends very, very little energy (way less than a standard display), and the device can last significantly longer if the user opts for this screen.

Next, this screen provides surprisingly good viewing angles and visibility on direct sunlight. The standard display can’t compare with E-Ink display in direct sunlight because it often becomes unusable. This feature might be very useful, as it saves tremendous amounts of energy, and can even display some images even if the battery is dead.

The two phones that we compare today are both rocking the E-Ink screen and are similar in other technical aspects. We present you Oukitel U6 and Siswoo R9 Darkmoon.

Oukitel U6

oukitel-u6-81-840x447
A battery life of 120 hours using the E-Ink screen

Build/ Specs 

The Oukitel’s handset released in August 2015 is a beautifully designed and assembled; the resemblance with other phones in the market is unavoidable, especially when you notice the bezels and the metal framing. This smartphone is powered by Mediatek MT6735M Quad-Core processor, which is a good one, but not the best solution out there – it has a similar performance levels of the Snapdragon 410, running at 1.3 GHz. The processing unit is backed up with 2 GB of ram, and 16 GB of internal storage, with possible expansion up to 32 GB, to a sum of 48 GB of storage. The specs are excellent, and the Android 5.1 will run without flaws on it.

Design, Screens

The front of the U6 smartphone uses a 5.0-inch screen, built-in IPS LCD technology and having a 294 pixels per inch – PPI. Not really dense, but this spec isn’t somethings that significantly matters to the end user. The screen looks good, colors are fine, and it will serve the user well for every essential occasion. The resolution is 1,280 x 720 pixels – 720p, which is not the best one in the era of 4K screen smartphones. On the other hand, this screen will provide a substantial experience and viewing angles. Next, there is a 4.7-inch E-Ink screen on the back, under the camera. This super-efficient screen can get you through the 120 hours of usage if you use it as a primary display. The E-Ink screen becomes the primary one when you turn it on, and the regular screen goes off.

Battery/ Connectivity

The Ouktel U6 packs a 2500 mAh unit, which is advertised to run up to 120 hours. The marketing trick used for this statement covers up the fact that it can run this long only if using the E-Ink screen; when you use the regular screen, which has a 5-inch diagonal, the battery can hold up to 3 hours 45 minutes of screen on time – this result is below average. Dual-SIM option gives you an option to connect to 2G, 3G, and 4G

Additional features

The phone runs on Android 5.1 Lollipop, has a Bluetooth connectivity, infrared blaster, and a decent storage. The E-Ink screen is the main feature that differentiates this phone from the competition, and on the dual-screen segment, this phone is among the best-looking ones.

Prices / Availability

This phone is priced at $239.99 / 1555.87 Yuan

The manufacturer’s site announces there are no available units for sale at the moment, as the phone was hot on its initial release, and they don’t have it in the stocks. On the other hand, some online sellers have it available.2

Pros & Cons, Our Opinion

The design, build, and the performance of the phone can definitely be considered as advantages. The device looks great, feels good in the hand ( a bit slippery sometimes), and the Android 5.1 experience is good. The resolution of the main screen can be considered as a downside; 1080p resolution is standard today. The E-Ink screen lives up to its name, and prolongs the battery life; on the other hand, not a magnificent performance in durability can be expected if you’re using the regular screen. The lack of wireless charging is another con that don’t affect the phone’s overall grade that much, but might be significant to some users.

The back screen is 4.7 E-Ink unit, which works on the different system. When the screen is energized, the ink will change color and display the image. That requires only a fraction of energy for image displaying.

E-ink screen has a lot of “microcapsules” attached to the surface. Their function is to channel the negatively charged black particles and positively charged white particles. By changing the particles in the ink cells, the capsules then move to their similar pair, and format to create the image on the display. This system is really efficient, and if the phone is used only for this screen, it can last for about 155 hours, or 10-11 hours of screen on time.

Pros & Cons, Our Opinion

The Siswoo R9 Darkmoon is a quality device, providing a wide array of functions, great battery life, a quality display and a secondary display which will be your best friend while reading books and want to save some more energy. There are few flaws that we can mention about this phone: besides the price at some stores, the in-call volume is sometimes too low, and switching between networks can sometimes be slow. It depends on the carrier. The older version of Andriod can be considered as a flaw as well, but updating to the newer version of the Android OS is available, and easy to perform.
