Among LG‘s cheap mobiles, the LG K40 and the K40s occupy an important place. We are facing two devices that do not even reach 150 euros, and are intended to penetrate those users who do not need large technical displays. Today we wanted to see the exact differences between both devices, to see which one is worth the most.
The battle in the entry range is very fierce. All manufacturers have bets below 150 euros and it is not easy to opt for one model or another. The LG K40s came as an improved review of the LG K40. It is true that it improves in some aspects, but in other technical points both terminals are very similar.
Screen and dimensions
The first thing we see is the difference between the screens, although not so much in resolution (both have an LDC IPS HD + screen if in size. The LG K40 has a 5.7-inch screen, while the K40s reaches 6.1 inches . Furthermore, the passage of time gives some disadvantage to the K40, wearing large frames at the top and bottom of the screen. the K40s looks more current appearance with a notch dropwise to achieve better connection between the screen and the body of the terminal.
We see an important difference in the weight of both devices, since the K40 weighs 144 grams, while the K40s has raised this value to 186 grams. In the thickness they are still very similar, although in this aspect once again wins the K40 with its 8.3 millimeters compared to the 8.6 millimeters of the K40s.
Same brain and memory
When we lift the hood we see that things are exactly the same in both terminals. Both integrate the MediaTek Helio P22 processor, a classic of the input range that cannot be asked for great technical requirements. Both have versions of 2 and 3 GB of RAM and a single version of 32 GB of internal memory , expandable by microSD cards.
Cameras
Where we do find differences is in the cameras section, which is where LG justifies the “s” label of the K40s. In this sense, we go from the only 16 megapixel rear camera of the K40, to a double rear camera with 13 and 5 megapixel sensors . I n the front there also changes as the chamber K40 is 8 megapixels, while the sensor selfie neigbourhood in the notch of the K40s reaches 13 megapixels.
Connections, battery and OS
Nor are there excessive differences in the connections of both terminals, which maintain elements such as the 3.5 jack. Interestingly, both devices, despite being so cheap, offer NFC connectivity, something to be appreciated in this price range. The LG K40 arrived on the market with Android Oreo, while the K40s did it with Android Pie, which gives it a lot of advantage in terms of battery performance and security. There is no hope that either of them ever see in their guts Android 10.
The LG K40 has a 3,000 mAh battery, compared to 3,500 mAh of the Lg K40s. This difference added to the management of Android Pie K40s, make the autonomy is totally on the side of the second.
Minimum price difference
As we say, we are facing two very cheap terminals. The LG K40 can now be purchased for about 119 euros, while the K40s goes up to 135 euros. We are talking about a difference of only 19 euros between the two. Because of this, there is no doubt that the K40s is a better purchase option.
