Digital Laboratory: We Test the Best Tablets in Brazil

Three top line tablets in the arena for a battle that promises to be fierce. In this month’s Digital laboratory we assess the main tablets available in the Brazilian market. We tested the appliances from Apple, Lenovo and Samsung. For treating top-of-line devices, functions and quality are not lacking in any of the appliances. But to elect a winner, we go to the comparisons between Apple IPad Air; Yoga Tablet 10, Lenovo; and Samsung Galaxy Tab S.


As always, design is the first impression. All appliances have metal finishing. We agree that design is a matter of taste, but pay attention to some details that can make a difference. The heaviest is the 10, Lenovo Yoga, with 610 grams; Next, IPad Air and Galaxy Tab S have virtually the same weight: 478 and 467 grams respectively.

Lenovo brings an interesting drawing, with a coupled support that allows you to leave it so, standing; It even facilitates the time to hold the appliance. Yoga’s 8.1 millimeters thick. Once again, IPad Air and Tab S are fairly close; The Apple tablet has 7.5 and Samsung, 6.6 mm thick. Although it is a matter of opinion, in the design aspect, Apple and Samsung begin this dispute with a technical draw; The two devices stand out, they are very fine and elegant.


Lenovo’s 10.1-inch LCD screen brings aboard the IPS technology and has HD definition of 1280 by 800 pixels. The IPAD also utilizes IPS technology, which allows for greater viewing angle, but the Apple’s 9.7-inch Retina Display has led back light and an even better resolution of 2048 by 1536 pixels. The Samgung brings not only the largest screen–10.5 inches–but also the largest definition; AMOLED screen 2560 by 1600 pixels.

Here we have two levels to compare. Lenovo with its HD screen and Apple and Samgung with Full HD screens. Yoga, of course, is in third position, beneath its opponents. Secondly, IPad Air does not allow you to be desired in color fidelity and high brightness. Anyone who has used an Apple device knows the quality of the Retina Display screens. Now the top definition of Galaxy Tab s is surprising. The contrast, brightness and colors of the Amoled screen of the device impress and leave no doubts; In this round, the Korean device takes the best.


For treating top-line tablets–the best of each brand–the performance of them all is superior to most models found on the market at Ablogtophone. But still, it’s possible to notice a certain difference between them. First, it’s worth taking a look at the numbers. IPad Air and Yoga 10 possess a giga of RAM; Already the Samsung device brings 3 giga of RAM.

Lenovo has in its heart a four-core processor with 1.2 GHz speed. The 64-bit IPad Air processor A7 also has only two cores and clocks of 1.3 GHz, but it’s worth remembering: in this aspect, it beats the device that delivers the best performance of the hardware and software assembly. Samsung’s handset once again stands out, at least in numbers: The quad-core processor reaches up to 1.9 gigahertz speed.

If what determines the winner in this round is the combination of the operating system and the processing of the appliance, here the fairest is to decree another technical tie between IPad Air and the Galaxy Tab S. The two appliances are extremely fast.

Operating system

In the Digital laboratory, we do not assign winners at this stage of the compared; Operating system is a matter of taste. But some important information can help when deciding.

Of the three models, only one has different operating system. The IPad Air and the new iOS8. Other manufacturers adopt Android, Google-led development software. Lenovo and Samsung bring the latest Kit Kat version installed on the appliance. Interesting is that Samsung opts for own resources, IE programs that modify the usability of the system; The Galaxy Apps.


Before you try the cameras, the settings of each appliance. Lenovo and IPad have 5 megapixel cameras; The Galaxy has 8 megapixels. The Apple tablet is differentiated by the crystal lens with five optical elements; While Samsung’s is the only one with Led Flash.

The photos on Lenovo Yoga 10 are good, but are still inferior to those of their competitors. The camera application brings several controls and the quality is already compared to the intermediate smartphones found on the market. Once again, on a much higher plateau, despite the same amount of megapixels as Lenovo, is the IPad Air. The definition of the image and color fidelity is fairly superior. And the new operating system iOS8 features interesting functions such as timer for selfies, time-lapse, panoramic photos and even luminosity control at click Time. But the round, once again, is defeated easily by Samsung Galaxy Tab S. The 8-megapixel camera combined with the ultra-high definition screen impresses. Color fidelity is the largest of the category and the application for photographing is the most complete of the three models. The flash is quite handy when low-light conditions; And the Korean model Front camera is also HD, with 2.1 megapixels. That makes it easy to choose…

Of course, all the tested smartphones also record videos and bring front cameras. As we just said, the Galaxy Tab S front camera is impressive. The device writes videos to Full HD with 30 frames per second. The IPad Air, also shoots in Full HD and brings an image stabilizer to avoid shaky videos. As well as its main competitor, the front camera, despite having only 1.2 megapixel, also writes in high definition. What drew our attention negatively was the positioning of the Lenovo Yoga camera 10; The camera is precisely at the bottom that they did to better handle the appliance–most of the time, to photograph horizontally, your finger will be in front. Smarter, to facilitate vertical and horizontal images, the Samsung handset is the only one that brings the camera strategically placed in the middle of the device.



The largest storage space model is the IPad Air, with 64 giga of memory. Then the models of Lenovo and Samsung bring 16 giga of internal space, but they offer the possibility to enlarge – and quite that memory – with the use of MicroSD cards. Thus, with the possibility of expansion and with the idea that memory is never too much, in this aspect Lenovo and Samsung reach a more tie than fair.


Test battery is a bit tricky, but experiments and information from the manufacturers themselves realize the following: Galaxy Tab S, Samsung has battery with capacity of 7900 miliampere-hour. According to Apple’s own data, IPad Air lasts up to 10 hours of use on Wi-Fi, with its 8600 miliampere-hour. Lenovo, promises the best energy efficiency of the category; A 9000 miliampere-hour battery lasting up to 18 hours of use with a single recharge. And with that data, Lenovo wins the round “drums.”


Bluetooth 4.0, Wi-Fi and GPS all tested models possess. 3g or 4g connections, only IPad and Galaxy Tab S bring and end up getting tied here too.


Galaxy Tab S has an ultra-battery-saving function and brings a biometric fingerprint recognition sensor that is well needed to unlock the appliance. The model also brings an infrared LED sensor that allows you to use the tablet as a universal remote control in a series of appliances.


Of course, your decision can weigh in your pocket. The Lenovo Yoga 10 is the cheapest of the three, with suggested price of 1250 real. Next, the Samsung Tab s, is sold for 2050 reais. The most expensive, but not much more than its biggest competitor is the IPad Air, which is found in stores by 2250 reais.

It is important to highlight that in the Digital laboratory we are not evaluating cost-benefit, but rather the best top-line tablet. Despite being the cheapest of the three, Lenovo Yoga 10 gets the third placement in this race. Still, the model stands out for the best battery between the three and the possibility to enlarge the internal memory with a MicroSD card. Second was Apple’s IPad Air. The device features excellent performance and the design that the Apple brand always stands out. But the great champion this time was the Samsung Galaxy Tab-S. The device features incredible performance with its 3 Giga RAM and its four core processor. The Korean tablet impressed by the quality of the Amoled screen and also with its 8 megapixel camera–In fact, it is the only model with built-in Led Flash. Not to mention energy efficiency and biometric reader. All these partial victories have consecrated Tab S the winner this time.
