You are probably already familiar with UMi Plus, the recent most addition to UMi’s fast expanding smartphone portfolio.

Boasting a 5.5-inch Full-HD display and powered by the Mediatek Helio P10 SoC, the UMi Plus is expected to play a critical role in UMi Digital’s ongoing efforts to establish itself as the destination for “budget flagships”.

So, quite obviously, the company has left virtually no stones unturned to equip its new-generation smartphone with all those features that make it a worthy rival to the products from already established brands such as Apple, Samsung, or to some extent even Xiaomi.


But as the average smartphone user understands very well, the more powerful the hardware inside a smartphone are, the worst effect they collectively have on the device’s battery life. Keeping that inconvenient fact in mind, UMi has made the right choice of going with a massive 4000 mAh battery with the UMi Plus.

The UMi Plus battery is manufactured using Sony cells, a 690Wh/L high-density unit that paves the way for a much more efficient performance compared to regular batteries with ‘traditional’ density units.

To prove its point, the UMi Plus was recently put under a series of tests designed to gauge the device’s overall battery performance. All tests were performed with 60% screen-brightness (of course with the exception of talk time which was carried out with the screen switched off).

Here’s a rundown of the test results:

umi plus battery performance

Talk time: With the screen off and connections inactive, the average talk time achieved by the UMi Plus in a 3G network stood at 32.45 hours. Pretty impressive indeed!

Internet browsing: With Wi-Fi connectivity active and the screen brightness set at 60%, the device managed to surf the internet for around 8 – 10 hours, which is undoubtedly much higher than the bulk of the devices in its league.

Video playback: This test was conducted with the screen set to 60% brightness level and connections switched off. A video was played in the loop until the battery completely discharged. While you would probably expect somewhere around 4:30 to 5 hours of media playback time considering the device has a 5.5-in full-HD display, it managed to surpass all expectations by reaching 7:20 hours.

3D Gaming: And finally, as game lovers would probably agree with me, there are few things in this world that can be as annoying as having to quit a game midway because of  those pesky “low battery” alerts. However, you probably wouldn’t have to go through those sickening times again if you chose to pair up with the UMi Plus. At least that’s what the test results suggest.

In the test (conducted under the same parameters as above), the device managed to run 3D games for a whopping 6:39 hours.

Now, we are not yet sure to what extent the sheer impressive performance of the UMi Plus will echo in real life usage of the phone. However, even if the device manages to pull off a performance anywhere close to those test results in practice, it will surely earn itself some serious credibility.

The UMi Plus is currently available for pre-sale for $179.99 and will be shipped starting Septmber 30th.
