Xolo WIN Q900S Review : The Lightest Windows Phone is Impressive

When Xolo announced its first Windows Phone, I wasn’t really positive and it was mostly because I have not seen other OEMs to come up with really good Windows Phone to the market apart from Nokia Lumia devices. Xolo proved me wrong here and in this post, I am detailing every aspect of the devices that is totally worth knowing about. If you want to watch the video, scroll down to the end!

Display & Screen:

This phone has left us impressed with its stunning, 4.7 inch 72P HD IPS  332 PPI display which can show more things i.e. text on the same screen size. The texts are sharp, action center has one extra item on quick settings, less scroll everywhere, and readability is a treat here.

Also I noticed that screen is pretty bright compared to the Lumia phones I have used till date. Even at low profile, the screen is visible but when you get out to daylight, switch to medium and it should work out. However if you used a Lumia with clear black, you going to miss it all the time.

That said, the response to touch and swipe is very good. You feel that when playing games like Asphalt 8 and Temple Run where you do swipe a lot.


Build & Design

While it’s not one of the toughest phone in the market but it’s definitely the lightest of all Windows Phone devices out there. The phone is really sleek, has an amazing grip with matt finish rear case. Xolo had to compromise a bit to get this sleek design out which means you should be careful not to drop the phone.

That said the phone is just   7.2 mm thick with rounded corners and a metal rig runs around the body to make it look premium and adds to the strength. The buttons are placed just beside the rig its inwards making it almost invisible when seen from the front. This arrangement also makes sure you do have easy access to buttons though they are little hard to press and it’s probably because you cant have thick buttons.

The rear of the phone houses the camera and led flash on extreme top left. This has little inconvenience though if you are used to cameras which are located on top center. Keep your fingers off the lens when taking the picture.

Those who want to know how strong is the scratch resistant Dragon Trail Glass, its little disappointing. I already have few scratches after using it over a week in spite of being pretty careful about using phones. Recommend using the screen guard which comes with the package.

Camera (Picture and Video Quality)

We have done a detail review of Camera for both day light and low light. If you want to get into details, follow this link up else just watch this video below.

Application Performance

This phone is powered by Snapdragon 200, 1.2 GHz processor and has 1GB RAM to do all the heavy lifting.

The hardware makes sure you wont feel any lags when using any app. I have used WhatsApp Heavily, Twitter and Facebook all the time and there was no problem. The notifications show up properly and launch time is pretty fast.

Game Performance with Asphalt 8 : Airborne

If I have to say it in one line—Brilliant Display, Amazing Performance and no Heating Issue. This device is perfect for gaming from every possible angle. The display makes sure the gaming experience stays sharp, there is no color variation and you experience every bit of it.

During my gameplay which ran over an hour, there wasn’t any performance lag even though the game was on Class 10 MicroSD card. A lot of wreck were enough to tell us that. However I did feel the FPS was kind of low which came in the way a lot many times.

Also, even being thin there is no heating issue even when you play for such long hours. Check out the gaming review below.

The battery drop was 1% on an average for every 15 minutes of gameplay with this game. It may change though when you change the game.


  • Day 1 & 2 ( 3G & Casual Usage) : Average of 15 to 16 hours.  (1st Charge)
  • Day 3: 3G / WIFI / Download / Music and Games:  12 to 13 hours.  (2nd Charge)
  • Day 4: Everything Possible and it still lasted for 14 hours.
  • Day 5: This was crazy and with almost everything it survived for 26 hours with 6 hours of standby time.

What you should notice is that the phone’s battery life improved after 2 charges. I used the phone a lot from every aspect on Day 4 and it still lasted for straight 14 hours. Not to miss the Day 5 results.

Apps used: WhatsApp, Camera, Asphalt 8 Airborne, Mehdoh for Twitter, Music, Facebook App and Messenger.

Overall, the battery performance is impressive The phone is going to last for all day i.e. 16 to 18 hours and you should be back to your charging station by that tome on an average.


The phone comes with 8 GB of internal storage of which you get 4.5 GB to use. While 8 GB is just fine for most of the users but if you want to expand, grab a microSD card of Class 10 and move all your apps. That class will make sure that you get performance and space both to get you the best experience.

Music Experience:

WIN Q900S comes with powerful speakers, loud enough for listening to music, watching movies and playing games. While the sound stays loud when you are holding, but it cuts down by half when you lay it on flat on a table. The phone rear is a perfect flat and there is no curve for the audio to escape.

When used with earphones, it delivers an amazing experience. I had no issues on level of loudness or bass.

A lot of people asked if the phone comes with equalizer and the answer is no and none of the players on Windows Phone,as of now, support that.

  • Performance - 8.5/10
  • Battery - 8.5/10
  • Music and Speakers - 8/10
  • Gaming - 8/10
  • Value for Money - 9/10


Overall a highly recommendable phone. Right from Display to Camera to Quality is great. Totally Worth the Money


Overall, it’s a highly recommended phone at this price point. Not only you get screen guard and a flip case as a deal, the amazing display quality, lightness of the phone and performance is brilliant. While camera is a great deal for day light pictures, the low light are not that good even though it has flash. Not to forget the battery life which will last for a day anytime.

That said, the phone is priced at Rs 10,000 or less and you can go ahead and buy it!
