Review LG L90 Smartphone

For the original German review, see here.
LG is another manufacturer that follows the trend towards product diversification and offers smartphones in all shapes and sizes. The L90 is one of the newer models and has a 4.7-inch display. The heart of the smartphone is a Snapdragon 400 SoC (MSM8226) with a clock of 1.2 GHz, four cores and one GB memory. The IPS display has a WVGA resolution of 960x540 pixels.
The smartphone is an entry-level mainstream device with an RRP of 249 Euros (~$345). LG launched numerous devices over the last couple of months and also produces the Google Nexus 4 and Nexus 5. If LG managed to implement the features of the mentioned smartphones into the L90, we can certainly expect an interesting piece of hardware.
Case
We cannot really support the "Design" claim of the manufacturer when we look at the case. In terms of visual design, the L90 is similar to many barrel smartphones. The case is primarily made of plastic and the structured back cover does not leave a very high-quality impression. The L90 measures 131.55 x 66.02 x 9.65 millimeters (~5.18 x 2.6 x 0.38 inches) and is wider and longer than the Moto G – but the situation changes in regard to the thickness (Moto G: 11.6 mm; 0.45 in). It is also superior in terms of weight; the L90 is around 19 grams (~0.7 oz) lighter.
We could not determine any build quality issues or uneven gaps at the LG device. That the torsion resistance cannot quite keep up with the Moto G is caused by the reduced thickness. You can currently buy the smartphone in black or white.
Connectivity
Contrary to the concept of the LG G2, the manufacturer equipped our review unit with the typical port and button layout. One positive aspect is the storage expansion via micro SD card. This may be mandatory since you can only use around 3.4 GB of the 8 GB integrated flash storage.
Software
Google’s current operating system is called KitKat (4.4.2) and is already preloaded on the L90. As usual with LG devices (for example LG G2), there are several preloaded apps and some software customizations. For instance, you can use a "KnockCode" to activate the device: A modification of the familiar pattern, where you have to touch areas of the display in a prearranged order.
Communication & GPS
Access to the Internet can be established via an existing data plan or WLAN module. On the road you can use UMTS (900/2,100 MHz), HSDPA 21 Mbps, HUSPA 5.76 Mbps or GSM (850/900/1,800/1,900 MHz). The WLAN module supports the 802.11 standards b/g/n; furthermore, you can use Bluetooth 4.0 for short-range wireless transfers.
The integrated aGPS module establishes a connection to the satellites relatively quickly. Our practical test with a bicycle and the reference device from Garmin (Edge 500) does however show that the accuracy is not perfect. Overall, the L90 is accurate to a distance of around 400 meters (~0.25 miles). That is just 3.4% of the complete track, but it is still annoying when you get an inaccurate result for your sports activities.
Telephone Functions and Voice quality
We could not determine any issues with the voice quality. There were no background noises or connection losses and we could clearly understand the person on the other end of the line. A small drawback is the hands-free feature because it is not loud enough. Here you should use a headset or an external device via Bluetooth.
Cameras & Multimedia
The main camera on the back has a resolution of 8 MP, whereas the front camera only uses a 1.3 MP sensor. An LED flash supports the main camera in darker environments – but you should not expect any miracles.
Compared to our reference camera, the pictures of the L90 are slightly too bright and colors sometimes appear too pale as a result. You can also see imprecise details and that the picture is not very sharp when you zoom into the picture on the computer (100%).
Accessories & Warranty
The warranty period for the L90 is 24 months, but the battery is only covered for 6 months. In the box of the smartphone is also an On-Ear headset.
Input Devices and Handling
Multi-touch inputs are absolutely no problem for the review unit: You can use up to eight fingers simultaneously on the screen and inputs are executed very quickly. There is hardly any delay between the input on the touchscreen and the execution. LG introduced the “KnockOn” feature with the G2 – but this is not the formerly mentioned “KnockCode” of the L90. You can activate the device with “KnockOn”, but the L90 unfortunately does not support this feature. We like the return of the dedicated navigation bar including the physical home button.
Display
The 4.7-inch display has a resolution of 960x540 pixels (WVGA) and can represent 16.7 million colors. The LCD IPS screen has a very even brightness distribution of 92% and can compete with the excellent result of the Wiko Stairway rival. We can determine an average brightness of 377.1 cd/m². The Moto G manages 416.8 cd/m², but the black value of the Motorola device is much higher compared to our review unit (0.54 cd/m² vs. 0.31 cd/m²). This results in a contrast of more than 1000:1 with 1,261:1 for the L90. The measured results of the X-Rite i1Pro 2 show surprisingly good performance.

The CalMAN screenshots show that red colors are too pale on the smartphone screen. The grayscale on the other hand is very close to the ideal value and the display has an average color temperature of 7,355 K. We can see a deviation from the ideal value with a brighter grayscale.
Thanks to the high contrast in combination with the decent average luminance, the display content is easy to read outdoors. Unfortunately, there is no brightness sensor, so you will have to adjust the brightness manually.
You might think that an IPS display usually offers very good viewing angle stability, however, not in this case. We can see that the contrast and colors fluctuate as soon as you look at the picture from the right top. Viewing from the left top results in a hardly visible picture because of the low brightness. Straight and slightly horizontal as well as vertical viewing angles, on the other hand, are no problem.
Performance
The Snapdragon 400 is already familiar, we reviewed the SoC multiple times in the past and it is used in many devices. The quad-core runs with 1.2 GHz, executes tasks very quickly and benefits from the Adreno 305 GPU. All that is supported by 1 GB memory. This combination is also used for the LG G2 Mini, Motorola Moto G or the Nokia Lumia 630.
Both the results of the Moto G and the L90 are very similar in several benchmarks and the MediaTek MT6589 from the Wiko Stairway is in the same ballpark as well. Samsung's Galaxy Core is somewhat of an outsider with its Renesas MP5232 – the dual-core can only keep up with the performance of the quad-cores in the Single-Core mode of Geekbench 3.

* ... smaller is better
The comparison of the writing performance shows that the storage module is not one of the fastest on the market. All rivals manage higher results, sometimes with an advantage of up to 425%. The situation does change with read operations; the L90 can beat all competitors, except for the Moto G in one benchmark.

Videos & Games
The Snapdragon 400 is powerful enough for Full HD movie playback or complex 3D games. QFHD videos are not supported by the SoC – accordingly, the smartphone has big problems with the playback of these contents. You should select a Snapdragon 800 if you want to watch these very high-resolution videos. The mentioned SoC can be found in many high-end devices, for example the LG G2, the Google Nexus 5 or the Xperia Z1.
Emissions
Temperature
The temperature development is very similar to the Moto G, but it is not quite on the same level. We can measure between 32.1 and 31.3 °C (89.8 and 88.3 °F) under load at the front and the back of the L90. These values drop by around 3 °C (~5 °F) during idle. We can see that the device only gets warmer in the top third in general with a maximum value of 36.5 °C (97.7 °F). However, this is still tolerable because you usually hold the smartphone at the bottom end. The temperature of the power adaptor is also okay with up to 40 °C (104 °F).
(+) The maximum temperature on the upper side is 36.5 °C / 98 F, compared to the average of 35 °C / 95 F, ranging from 21.9 to 56 °C for the class Smartphone.
(+) The bottom heats up to a maximum of 34.1 °C / 93 F, compared to the average of 33.8 °C / 93 F
(+) In idle usage, the average temperature for the upper side is 29.2 °C / 85 F, compared to the device average of 32.7 °C / 91 F.
Energy Management
Power Consumption
The power consumption mainly reflects the efficiency of the hardware combination. Do they work well together and how good are they adjusted to each other? The consumption is between 0.5 and 1.2 Watts during idle; maximum load for the quad-core results in 1.6 up to 3.2 Watts. These are good results, especially when you consider the bright display. However, the competition from Motorola shows that there is still room for improvement. The Moto G is more frugal, despite the even higher luminance. The only way to beat the battery runtimes of the Moto G is a higher battery capacity.

Battery Runtime
We already mentioned that LG has to compensate for the high consumption with a larger battery capacity. 2,540 mAh is actually rather generous – almost 500 mAh more than the Moto G. Another advantage is that you can easily replace the battery.
We used several tests to see if the larger battery capacity results in the desired success. Two of three scenarios show that LG’s decision was correct: We can measure a runtime of 4 hours and 11 minutes for the L90 under load. This is a small lead over the Moto G, although only by a couple of minutes. We can determine a bigger advantage in the WLAN test, where our review unit beats the Motorola by 3 hours. The idle test, on the other hand, favors the competitor, although only by around 35 minutes.
Verdict
LG’s L90 is supposed to rough up the mainstream segment. The specifications are similar to the Motorola Moto G, however, the South Korean manufacturer cannot compete in terms of price – but more on that later. The Snapdragon 400 provides sufficient performance, and the 4.7-inch display manages an average brightness of 377 cd/m². The case materials leave a somewhat cheap impression, but the handling is still good thanks to the structured back cover. We also want to mention the battery runtimes: Almost 24 hours with an activated display is very enduring.
Deciding between the Moto G and the LG L90 is certainly not easy. One of the biggest drawbacks of the competition is easily solved by the L90 – you can just extend the small internal storage (8 GB) with a micro SD card. You can currently get the L90 (black) for 235 Euros (~$326). If 8 GB flash memory is sufficient for you, and you want a display with better viewing angles as well as an HD resolution, then we can recommend the Moto G (8GB) – the price is around 75 Euros (~$104) lower.
