Oppo R7 is quite an interesting smartphone, which upgrades on the super thin Oppo R5. The new R7 brings back the 3.5mm jack and adds extra battery capacity at the price of 1.4mm of extra thickness. We also get dual-SIM connectivity, a microSD expansion slot, a higher-res selfie camera and enhanced rear snapper this time around.

The Oppo R7 keeps the same key hardware specs – a 5″ AMOLED 1080p display, the same Snapdragon 615 chip, this time around with 3GB of RAM, and runs on the aging Android KitKat. The older Oppo R5 returned a disappointing endurance rating and we hope Oppo managed to fix this issue for the successor. Read more »

Samsung Galaxy S6 Active features a massive 3,500mAh battery. The rest of the rugged device’s internals are identical to those found in the regular Samsung Galaxy S6, so we were quite curious to put it through our battery test.

With roughly 40% more battery capacity than its non-rugged sibling, Samsung Galaxy S6 Active commands seriously high expectations. Read on to find out if the device delivers! Read more »

We recently gave the Huawei P8 a thorough review and, naturally, we didn’t skip on putting it through our rigorous battery testing procedure.

When examining the Huawei P8, and any of its siblings, for that matter, we really have to take into account the custom nature of their internals. Huawei has been straying from the herd and relying mostly on its custom Kirin architecture, courtesy of HiSilicon. So, even though, the ARM Cortex A53 cores, found it the handset are more or less standard, their performance and power consumption is slightly different from what Qualcomm or Mediatek offer.

Xiaomi Mi 4i turned out quite an interesting smartphone, a worthy alternate of the original Mi 4. The new Mi 4i model changes the design, keeps the 5″ screen and 13MP great camera, but comes running on the Snapdragon 615 chip. There is a beefy 3,120 mAh battery, which should keep the Mi 4i up for days.

The MIUI v.6, just like before, offers Performance and Balanced power modes. The Performance mode allows the phone to use all processor cores, while the Balanced limits the CPU usage in order to save battery. Throughout our tests – call, video, browser and standby we used the Balanced mode, as any MIUI users will do most of the time. We tried switching to Performance and re-test the device, but we noticed just minor differences in the results. Read more »

The AKA’s display is decent at 5″ and 720p resolution, but its Snapdragon 400 chip is rather dated.

The vivo Xshot just made it through out rigorous review procedure and didn’t do too shabby in terms of battery endurance. But, there are still a few things to note on the matter and we intend to do so in the following paragraphs. And if you want to check out the full, in-depth review, you can do so right here.

The vivo Xshot boasts an impressive specs sheet, featuring a Qualcomm MSM8974AA Snapdragon 801 chipset with Adreno 330 GPU, 2GB or 3GB of RAM, depending on the version and a 5.2-inch IPS LCD display.
