Starmobile Diamond X1 first impressions, benchmarks

We’re able to get a hold of a commercial version of the Starmobile Diamond X1. Some units were already available in the market as early as January 31 (same day this unit was bought in SM Megamall Cyberzone).

The handset did not fail to impress the first time we saw it. While most of the buzz around it was about the octa-core processor, we reckon the design and build quality should be equally given attention.

The Diamond X1 does pretty well in the design department. It looked simple yet feels solid and comfortable to the hands.

Despite the large form factor (a 6-inch display), the Diamond X1 doesn’t feel like a huge phablet. This is probably due to the very slim profile that allows for a good, comfortable grip. At 7.5mm, it is probably among the thinnest in its size category (the Xperia Z ultra is 6.5mm while the Galaxy Mega is 8mm).

The white and gray tones make it look simple yet elegant, but it could pose some problems in the future in terms of smudges and fading. The silver trimming is a pretty common accent but were not complaining.

The back side is painted with a silver-metallic finish along with whiter paint jobs at the top and bottom to give the body an aluminum-alloy look, despite it being a thin sheet of polycarbonate material.

The large camera lens is flushed right close to the top right corner along with the tiny LED flash. The Yamaha speaker grill is right across it and there’ another one on the opposite end.


Up at the front is the 6-inch IPS LCD display with 720p resolution that’s decent enough even for its size. The display quality is good, images are crisp and clear and the only time you will notice the pixels is if you look a little closer to the screen.

The capacitive touch buttons are lined up at the bottom end (Menu, Home and Back) and you get haptic feedback for every tap of the screen.

Starmobile uses its own custom UI on top of Android 4.2 Jellybean. It looks simple, nothing fancy but really clean and well-done. The handset performs well, is very snappy and loads apps quite fast. Gaming is also equally good and so are the dual Yamaha speakers at the back.

Starmobile Diamond X1 specs:
6-inch IPS LCD display @ 1280×720 pixels, 245ppi
Scratch-resistant coating
MediaTek MT6592 1.7GHz Octa-core processor
Mali 450MP4 GPU
8GB internal storage
up to 64GB via microSD card
WiFi 802.11 b/g/n
Bluetooth 3.0
18MP BSI auto focus camera with LED Flash
8MP BSI front-facing camera
Dual-SIM, dual standby
GPS w/ aGPS support
FM Radio tuner
2 x Yamaha 1420 speakers, 1.2watts
Li-Ion 2,400mAh
Android 4.2.2 Jellybean

The final battery rating of the Diamond X1 is only 2,400mAh. This could be the only deal-breaker especially if you use mobile internet all the time. We’ll be testing the battery life with our standard bench in the full review.

We also took a bunch of benchmarks on the device and got these scores.

Benchmarks scores for Diamond X1:

Quadrant Standard: 16,069
Antutu Benchmark: 27,490
Nenamark 2: 60.2fps
Vellamo: 2,086 (HTML5), 653 (Metal)
SunSpider: 1,106.4ms

The Antutu score was pretty high, coming close to the Snapdragon 800 of Qualcomm. So is the Sunspider score (lower is better).

The Starmobile Diamond X1 got us very impressed in the first take. It is really good and very promising for a local brand. We will find out more on our full review in the coming weeks.

    The phone looks so good, and the benchmarks kick ass! But with the battery, I don’t think this will hold up to long usage hours because of its 8-core procie.

    • Miko Puracan says:

      One of the best smart phone released by starmobile!
      The battery capacity is not a big deal, it is actually an advantage kase removable naman. Battery price is between 350 to 500 pesos

    • Shuya says:

      You can buy a motolite to make it running for 1 year. Dont buy it if you think the 2400mah is not enough. Just my 2 fuc_ing cents

  2. meh says:

    Mediatek, no LTE, small battery

  3. roiji says:

    *slow clap* pwede na..
    And dat yamaha speakers… :D
    How much nyo nabili?
    At gumagana ba yung FM Radio Tuner?

    Starmobile did a terrific Job releasing this masterpiece. 2,400mah battery is really not a big factor since optional power banks are already available in the market and the Octa Chip-set as what they say is power efficient. Kudos Starmobile!

    • Jax says:

      Sorry, but the ‘power banks are already available’ excuse won’t cut it. As a phone user I want to continue using my phone without the need to undergo the hassle of charging it with a third-party device.

      I’m crossing my fingers that the octa-core itself would help prolong the 2400mah battery of X1.

  5. maki says:

    dual sim + octacore + small battery capacity = killer combo as in dead on arrival sa market. sumama lng sa octacore bandwagon. kng mhrap pa signal ng sims mag durog battery mo

  6. jan suico says:

    I’d prefer the Cherry mobile Z2 Octa-core over this. The winning proposition is of the “availability”. the Z2 is already on shelves here in cagayan de oro while the SM X1 has yet to arrive. Why would i consider a phone that only exists in blogs and over hyped.

    • zhel says:

      Just got mine. It’s available in most major malls here in manila… nice phone. But the cm phone looks nice too.

  7. Saw this phablet in Lazada and I’m seeing the battery specs at 3000mAH. Hope it’s not a typo.

  8. jadgreat says:

    hehe lahat na lang battery ang problema. hahaha pano nyo ba gamitin ang fone nyo? walang patayan ang screen? hahaha

  9. Vanessa says:

    I’m not a gamer or a multimedia fanatic. I don’t even watch movies on my phone. Moderate phone user usually for work and acads.

    Is Diamond X1 a good buy? (I’m after the screen size)
    Or is Starmobile v7 better? (considering my needs?)

    • gvmm says:

      Got this unit a week ago and like you I’m a moderate user. The X1 is a good buy from my one week of use. So far am happy with the unit. With moderate use I think battery will last 1 1/2 days to 2 days from my experience. Really don’t know why there are a lot of negative batt life reviews for this unit. In my opinion batt life is very good. If you plan to get this unit I suggest you get the original flip case, it has a magnet on it that shuts the screen down when you close it. This may help is save battery life too.

    • ferdie n says:

      Hi gvmm, where did you bought it and how much?have you tried using it online for a long time?thanks

  10. Elmer says:

    I recently bought X1 and its great. Speed is superb. Everything is Great!
    But I am not that favorable to Diamond X1’s camera, its somewhat similar to chinaphones.
    But overall, X1 is great and hope it will do good for me in the future… out of the country
