Nokia Asha 503, in-depth analysis


Not only do mobile manufacturers live in high-end ranges, and speaking of Nokia, this is even more valid . The Finnish company has shown its novelties in phones this morning, where the new tabletphones of the Lumia range and its tablet have shone . But the budget range, Asha , has also had its share of prominence.

The Nokia Asha 503 is the most prominent model in this segment, and it is already a smartphone with all the letters . With a three-inch touchscreen , 3G connection and a 5 mpx camera , the Asha 503 is not the most advanced smartphone on the market, but it sure is one of the cheapest. Nokia still has emerging countries in mind, as well as users of basic phones, who want the most features at very low prices.

Below we thoroughly review all the features of the Nokia Asha 503


Design and display

The LCD screen has a diagonal of three inches in length. It is a screen size that a few years ago was considered normal or even large. However, today it is one of the smallest smartphones on the market. It has a resolution  QVGA (320 x 240 pixels ). It is also far from the big markets in this regard, although with the screen size we are talking about, it cannot be said that it is insufficient. If we measure the resolution in relative terms (pixels per inch) we get a value of 134 ppi. It is not a spectacular figure either, but it is very much in line with the entry models that we find on the market.

Nokia has opted for a 4: 3 aspect ratio in this model . It is the most comfortable format for browsing the Internet, but less practical if we want to watch videos. Given the nature of this terminal, it does not seem that it is oriented precisely to this last function, due to the small size of the screen and the fairness of the resolution, so the 4: 3 ratio seems more convenient than the 16: 9 that we find in larger screen models. What the Finns have included is a Gorilla Glass 2 screen that protects to some extent from bumps and scratches due to impact.

The design of the terminal is quite casual and colorful, very much in line with the Lumia range, its "older brothers" . The model will be available in six colors (white, black, red, yellow, green and blue) and has a transparent protective cover that wraps the entire set.

Despite being the lowest range of Nokia, the camera performs quite well. And it is that photography is one of the most important points for those of Espoo, who have never neglected this aspect in their terminals. On the back we find a 5 mpx camera , with quite acceptable values. However, no camera has been included on the front of the phone.

The camera has a fixed focus system and allows an optical zoom of up to three times . In case the light is not enough, it has an LED flash that can also work automatically. You have the possibility of enabling some automatic image modes such as landscape or portrait so that the camera settings adapt to the type of photo we are going to take. Likewise, different color modes such as black and white, sepia, grayscale or negative also work.


Operating system and applications

Original text

For the Asha range, Nokia has its own operating system called Nokia Asha 1.2. It is a simple ecosystem, quite similar to the Windows Phone 8 that we find in the higher models of the Lumia range , but adapted to work on smaller phones with less power.

In it we can download many of the most important applications that we find in the largest application markets. In this way, we find apps like Facebook, Whatsapp, Line or Linkedin.

Among the most important own applications that the Finnish brand includes, we find  Nokia Xpress, a browser designed to consume little data, and the FM Radio functionality , something simple that is missed in too many mobile phones today.


This is the most important point of this phone, which sets it apart from the other Asha presented today. Unlike its little brothers, it can connect to 3G networks , which are used by most smartphones in our country today. In this way, you can browse pages at an acceptable speed even if we are not connected to a home WiFi network . In fact, it is compatible with HSDPA networks, also known as 3.5 G or 3G +, faster than traditional 3G.

With these connections, the Nokia Asha 503 can be considered a full-fledged smartphone . And it is that this range of phones had not stood out until now for the Internet functions. Also, do not forget some of the other connections that give more game to a mobile.

On the one hand we find the GPS antenna . In this way, the phone can access a multitude of functions. We can use the mobile as a browser when we walk or with the car. In addition, we can play with a multitude of applications that allow us to geolocate photos, send our location or point out where our favorite places are on a map. It also has bluetooth 3.0. This technology allows you to send data to other devices or use wireless accessories such as headphones or handsfree.

As physical connections we find a microUSB port to charge the battery or exchange data. This port has become a standard in today's mobiles, since practically all smartphones use it. In this way, we can find a multitude of accessories that work with it or exchange chargers with other devices. Another physical connection is the Micro SD card slot. It supports drives up to 32GB capacity.



As we have said, the Nokia Asha 503 has the possibility of integrating micro SD cards of up to 32 GB capacity. But the good part is, the bad part is that the internal memory of the phone is, for all practical purposes, non-existent. That's why all drives will come in the box with a 4GB capacity card . It is up to the users to decide whether to purchase a larger capacity one.

Autonomy and price

In this section we find the best and the worst of this model. The best thing is without a doubt the price, which will amount to 100 dollars (about 75 euros). It IS a very low price for a smartphone. The features of the Nokia Asha 503 are not spectacular, but it can fulfill its function very well if the user is not too interested in having the latest model on the market. In addition, for many consumers the size of these models is excessive, so a three-inch phone can fit very well with their expectations.

The worst is undoubtedly autonomy. The 1,010 mAh battery does not seem enough to power a phone with WiFi, 3G networks and a 3-inch capacitive screen. In fact, the same autonomy data provided by Nokia is not very encouraging in this regard. They claim that it lasts about 4.5 hours of 3G browsing and 12 if we do it at the (very) slow speed offered by a 2G connection. They are very low figures, even compared to phones in the lower ranges of other manufacturers.
