Sharp B10 Smartphone Review

Florian Wimmer (translated by Mark Riege), 09/05/2018

Expensive for what it is. At 299 Euros (~$345), the Sharp B10 is at the classic price level of a mid-range device. However, at that price the equipment is not that good, so did the newcomer to the Western smartphone market miscalculate here?

Sharp B10

Sharp is back in the Western smartphone market. The Japanese brand is a well-known manufacturer in its homeland, and now two of its smartphones have arrived on the Western market; we already tested the Sharp Aquos C10 and found it to be good. While the Sharp B10 is 100 Euros (~$115) more affordable at 299 Euros (~$345), this is still at the mid-range level as far as the price goes. Anyone looking at the equipment will be disappointed initially: there is no fast ac-WLAN, only 32 GB of storage, and Android 7.0. On the other hand, the smartphone is supposed to convince with a dual camera system and a large battery, so we are curious.

As comparison devices we select the JVC J20, which is slightly more expensive, and also the BQ Aquaris X2, the Honor 10, and the Motorola Moto G6 Plus.

Case – Sharp smartphone with a plastic case

At a thickness of 8.8 mm (~0.35 in), the case of the Sharp B10 is a bit bulkier than the cases of the comparison devices, and you can also notice this when holding the device in your hand. The case is made of plastic, which is surprising for a device costing almost 300 Euros (~$346), but at least there is a metal frame. The black case is modest and the only design highlight is a beveled edge on the metal frame. The back is matte and not very prone to fingerprints. While pressure on the back has no effect on the smartphone, applying medium-strong pressure to the front becomes visible in the liquid crystal of the screen.

Size Comparison

Equipment – Small storage for the price

3 GB of RAM and 32 GB of storage are less than in comparable devices, and 4 GB of working memory and 64 GB of storage would have been the standard at this price range. While a microSD card can expand the storage by up to 128 GB, in our test the 64-GB storage card from Toshiba was not recognized, so we had to use a 32-GB model. The card can be formatted as external storage, but you cannot move apps onto it.

Software – Aging Android version on the Sharp B10

A fairly pure version of Android 7.0 is preinstalled on the smartphone, which is an older software version considering the recently published Android 9. In addition, after installing the most current update, the security patches are on the level of May 2018, which is dated at the time of this test. It is not clear whether there will be an update to more current Android versions.

Sharp only made some changes in the visuals, and the Settings look different than in the standard Android. It is laudable that the manufacturer did not preinstall any bloatware, i.e. software from third-party vendors.

Communication and GPS – No fast WLAN and the GPS has problems

The Sharp smartphone does not support WLAN according to the 802.11 ac standard but only supports the older n standard. This also shows immediately in the test with our Linksys EA8500 reference router, where the transfer rates are significantly slower than in all the other comparison devices. Although pages load relatively fast, you have to wait quite long for the pictures.

With six LTE bands, the most necessary are on board, but anyone traveling a lot will not be able to find an LTE connection in many countries. In our short test, the reception quality was decent in the German D2 network, and we had at least half the reception indoors as well.

GPS outdoors

While the GPS module is unable to locate us indoors in rooms with a concrete ceiling, outdoors it quickly finds a GPS signal that locates us at an accuracy of an acceptable seven meters (~23 feet). There is no compass, so that you cannot see your viewing direction in Google Maps. However, the location is quite accurate.

On the other hand, we were unable to get any decent results in our GPS practice test with the Runtastic app, and the GPS did not record our route even after multiple attempts.

Telephone Functions and Voice Quality – The Sharp B10 offers a good voice quality

Strangely the Telephone app is represented by a Contacts icon instead of a phone earpiece. It differs slightly from the standard look of the Google app but offers similar functions. We were unable to find VoLTE support in the software.

The voice quality is quite good. Although there is some slight background noise and our conversation partner does not sound completely clear, we can turn up the volume of the earpiece quite loud without the voice of our conversation partner becoming boomy. Our own voice is transferred clearly and easily understandable. We can also make phone calls with a good quality via the speaker in hands-free mode.

Cameras – A dual camera system with average quality

Picture taken with front camera
Picture taken with front camera

There is a dual camera system at the back of the Sharp smartphone. The main lens has a resolution of 13 megapixels and the second has a wide-angle characteristic with a resolution of 8 megapixels. You can switch easily and quickly between the two lenses in the app. The detail representation of the main camera is mediocre. Apparently the lens and software have more trouble with red objects in the image calculations, and there is very little detail in the red flowers. In the surrounding image, the details look muddy. There is strong image noise in weak light conditions, but at least the detail reproduction and brightness are decent.

Videos can be recorded in Full HD at 30 FPS. While the colors could have been a bit more vibrant here, the exposure reacts quickly to changing light conditions and details are reproduced fairly well.

The front camera also has a 13 megapixel resolution, but has problems in bright areas which quickly become too bright. Otherwise the color reproduction is vibrant and also fairly rich in detail in terms of its sharpness.

In our lab tests under controlled light conditions, the smartphone reproduces the test chart quite dark. With black text in front of a brown background, you can hardly see a difference anymore. The problems reproducing red areas also show up here, and the text on a red background appears blurry. Areas also appear grainy. While in terms of the color reproduction, the color areas also do not appear very cleanly, the colors themselves correspond relatively accurately to those of the reference color space.

Accessories and Warranty – Standard warranty

The box only includes the charger, a USB cable, and a SIM tool.

Sharp offers a 24-month warranty on its smartphones.

Input Devices and Operation – Easy operation, good fingerprint sensor

Google's GBoard is used as the keyboard app, allowing you to type quickly and smoothly. You can also download and install other keyboard apps from the Google Play Store, if you like.

The touchscreen offers a good surface and can also be operated easily in the corners. The navigation keys for the menus are on the screen, and the only physical buttons are the standby key and volume rocker on the right side. Both can be felt easily and activated precisely.

There is a fingerprint sensor on the back that reliably unlocks the smartphone from standby with minimal delay.

Display – Low resolution, decent brightness

Subpixel grid
Subpixel grid

There are only 1440x720 pixels in the 5.7-inch display of the Sharp B10. That is very little for this price range, and all the other smartphones in our comparison offer at least a Full HD resolution that has been expanded to the 2:1 format. At 549 cd/m² on average, at least the brightness is quite decent, but we can also find brighter screens in our comparison here. The brightness distribution is also okay at 90% but is not a top value.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8838 (minimum: 43 - maximum: 142900) Hz was measured.

We do not detect any PWM flickering. At 0.63 cd/m², the black value is also quite high, causing a significant gray veil in dark areas. The contrast ratio is mediocre at 889:1.

Our tests with the spectral photometer and the CalMAN software reveal a slight blue tint in the display. While the sRGB color space cannot be covered completely, the color deviations remain within limits.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
14 ms ... rise ↗ and fall ↘ combined↗ 3 ms rise
↘ 11 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 10 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.8 ms).
       Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined↗ 27 ms rise
↘ 21 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.3 ms).

Outdoors, the smartphone benefits from the decent display brightness. However, you have to live with the reflections on the shiny glass display.

The viewing angles of the IPS display are good, and there are at most only minimal color shifts at viewing angles from the side.

Performance – The Sharp B10 is quite slow

Quality journalism is made possible by advertising. We show the least amount of ads whenever possible. We intentionally show more ads when an adblocker is used. Please, switch off ad blockers.

The MediaTek MT6750 is a still fairly young SoC that brings hardly any current technology. For example, it is still manufactured in the 28-nm process, which causes it to be less energy-efficient than SoCs that were manufactured using a more modern process. While with 8 cores and 1.5 GHz, the performance potential of the Sharp is not really too small, it still remains in last place far behind the similarly priced comparison devices, and that is the case in all the benchmarks. The ARM Mali-T860 MP2 graphics unit does not fare any better.

* ... smaller is better

In terms of the storage, our first problem is that it does not recognize our Toshiba Exceria Pro M501 reference storage card. For a 300-Euro (~$346) device such as the Sharp B10, this should not happen. So we are forced to use the much slower Kingston storage card with 32 GB. The access rates are disappointing correspondingly. In terms of its internal storage, the Sharp smartphone also presents itself with slower access than its comparison devices.

Games – Current games are playable on the Sharp B10

Thanks to the low resolution, current games such as Asphalt 9 can run on the Sharp B10 and the frame rates are also fairly smooth. However, the selection of graphics interfaces is limited. For example, the graphics unit does not support the modern Vulkan interface, which might create some problems in terms of future proofing. We are able to evaluate the input via position sensor and touchscreen easily in Temple Run. Operation is quite fast and does not represent any limitation during gaming.

Temperature

While at a maximum of 42.2 °C (~108 °F) the Sharp B10 does get warm, the warming never becomes uncomfortable, particularly since its location is very limited. During idle operation we hardly notice any warming.

Speaker

Pink Noise speaker test
Pink Noise speaker test

The volume of the small speaker on the bottom edge of the Sharp smartphone is good, but the sound is very slanted towards the highs and therefore slightly thin. You can hardly hear any deep mids. While this causes voices to sound clear and the speaker does not know any booming, music does not sound very attractive.

There is a 3.5 mm audio port on the bottom edge of the smartphone. Using this or via Bluetooth, you can connect external audio devices which works without any problems and causes the sound to improve significantly.

Battery Life – Sharp smartphone with a good battery life

Power Consumption

The Sharp B10 is neither particularly efficient, nor does it consume too much power – instead it levels out at medium values. There are definitely more efficient devices in our comparison. If we consider the lower performance capabilities of the Sharp smartphone, we must say that the power consumption is quite high for this.

Battery Life

Lasting 15:03 hours in our WLAN test, the Sharp B10 strikes a very good figure in terms of its battery life. The strong battery with 4000 mAh is responsible for this, which theoretically allows it to even last for almost two workdays of constant usage. So in everyday use, you do not need to look for an outlet all of the time. 

Quick Charge is supported, and the included charger completely recharges the battery in slightly less than two hours.

At the time of our testing, there are not really any price drops for the Sharp B10 yet, and most vendors still charge 299 Euros (~$345) for the smartphone. In our opinion this is quite a lot for what it offers: a quite small storage, a comparatively slow SoC, fairly slow WLAN, problematic GPS and then there is also only a bland plastic case.

In addition, there is no information on an update to Android 8 or even 9, and at the time of the test the security patches are already quite old. We could live with that for 100 Euros (~$115) less, but the 300-Euro (~$346) price range offers so many good smartphones at this point, that the Sharp B10 will really have a hard time at that price.

The good battery life, the decent voice quality, and the low temperature development are positive aspects. The display also offers fairly decent measurement results, but at 1440x720 pixels, the resolution is much too small for this price range.

At 300 Euros (~$346), the Sharp B10 is too expensive, despite its good battery life. Even if you can get it for cheaper, you still have to live with some problems.

The Sharp B10 also surprises us with its bad price-performance ratio, since the Sharp Aquos C10 was a good smartphone. At least you should hold off purchasing the Sharp B10 until the price drops.

Due to the bad price-performance ratio and the problems with the microSD and GPS, we deduct two percentage points.
