Acer TravelMate 5740 Battery

This extends to the rest of the tablet as well. Take the famous kickstand at the back, for example. There's a slightly raised hinge along the sides, and it's easy to pull out with just two fingers. The stand looks thin, but feels very sturdy, and won't move even if you hammer away at the keys when typing, and use the touchscreen regularly. Everything is put together nicely, feels incredibly durable, and looks premium. There's a huge range of movement available to the kickstand as well - it allows you to set the tablet almost flat against the table - it might not always be a useful way to set up the screen, but there could be some times when it makes sense. At the other end, it can lean forward to nearly perpendicular. This means that you can adjust the angle fairly easily to use the Surface Pro 4 in a way that's comfortable for you. In this way, it feels a lot more like a laptop than the iPad Pro.

The same can be said about the Surface Pen as well - it works really effectively (although there were a few issues with palm rejection, which we'll address in the Performance section) and feels remarkably well built. It's accurate to use, and displays a small pointer on the screen when you're hovering close to contact - this allows you to be extremely precise with the Surface Pen. At the same time, it's relatively thick compared to many other styluses we have used, and this is a plus point, in our opinion. The extra size allows for a comfortable grip and the added heft allows for greater precision. We're not artists, but for simple sketching, the Surface Pen was excellent to use, and it also works extremely well for note-taking.

Windows has long allowed for handwriting recognition input, and this works fast and fairly accurately with the Surface Pen as well. You can't write as accurately or as quickly with the Surface Pen as you would be able to type, but using something like One Note, you can easily sketch down notes when you're talking to someone. It's a pretty reliable way to make handwritten notes that can be backed up to the cloud instead of being lost in notebooks. And our favourite thing about the Surface Pen is that you don't need to keep charging it up - Microsoft claims that the battery will last for 18 months, using coin cell batteries.

The Surface Pro 4 Type Cover Keyboard was the only area where we had a few problems with the hardware we were using. Considering how slim the keyboard is, Microsoft has accomplished something truly impressive in getting the keys to have this much travel, and the design includes a backlight as well. It's an impressive feat. However, the keyboard is really light, and doesn't really counterbalance the weight of the tablet. This means that the whole thing does shake a little when you're typing. It's not enough to make you unsteady but it feels uncomfortable. Also, the slight angle at which they keyboard is raised can't be adjusted so you really have only two choices there - completely flat, or fully raised. We actually preferred the former, as it gave the tablet more stability.

Because of how light the cover is, it doesn't really provide any stability if you're trying to use this laptop on your lap either; you can rest it there and type, but the whole thing does feel hugely unsteady. In our experience, it was best to tilt the kickstand a little extra, and then brace that against a raised knee, instead of trying to keep the stand level with the keyboard. This is workable, and also the setup in which around a third of this review was written, but it's actually not the most comfortable way to use the Surface Pro 4 for extended durations.

There is one thing we really loved about the keyboard though - that is the trackpad on it. This is fairly small, but hugely responsive, and extremely accurate. It has a really smooth feel and one that we enjoyed using consistently over the entire period of the review. In comparison, the ones we've used on most other laptops have a lot more friction, and just don't feel as smooth and comfortable to use; which is a big reason why a mouse is usually plugged into our work laptop.

The Microsoft Surface Pro 4 we reviewed was the entry level model, priced at Rs. 89,990. This model comes with a 6th generation Intel Core i5 processor clocked at 2.40GHz, along with 4GB of DDR-3 RAM, and 128GB of storage. The tablet comes with a number of ports, as discussed earlier, and also includes built in speakers with Dolby sound. As you'd expect, you can't upgrade the parts in this tablet, so whichever model you buy, the specs are final and can't be changed down the line.

The 12.9-inch display runs at a resolution of 2736x1824pixels (4K), at a density of 267ppi. At the typical viewing distance for a tablet or laptop, this is quite spectacular. Everything looks sharp on the screen, and reading text at a small font size is quite easy. The screen is great for watching movies on, or playing video games. The viewing angles are similarly comfortable. You can look at the screen from the sides, and recline it to the angle that's most comfortable for you without losing out on the visual fidelity. It's a huge step forward from the typical Windows laptop screens you get, and that makes this a really comfortable computer to work on.

Obviously, the display is also a touchscreen, which means that you can use it as a tablet without any accessories. It's quite responsive - there was never any instance where it didn't pick up a tap or swipe - although there are a few issues related to the on-screen elements which we'll discuss in more detail in the next section.

As already mentioned, the device is not overburdened with connectivity options. There is a single USB 3.0 port that you could of course plug a hub into if you feel the need. The Mini DisplayPort can be used to connect to a monitor, and otherwise there is the 3.5mm jack for your headphones. This will be a bit of a problem if you're used to working with a number of different accessories - the lack of an Ethernet port was particularly annoying for us because the wired access in office is much more effective than our internal Wi-Fi. Having a single USB port also means that we had to disconnect our mouse every time we had to use the port for a thumb drive, or to transfer pictures from our phone. You can argue that with the smooth trackpad and the responsive touchscreen, you don't really need to use a mouse, but if you're used to working in a certain way, then this setup could be a little inconvenient.

As is to be expected from Microsoft's flagship device, the Surface Pro 4 comes with Windows 10 pre-installed, and no bloatware to speak of. Windows 10 runs very smoothly on the Surface Pro 4, but there are some inconsistencies that are quite annoying and hard to fix. For example, there are small issues in setting up things like Cortana and the Surface Pen. We had to go through the setup multiple times before we could use either of the two correctly, which feels less than ideal. When you're actually using the Pen, palm rejection works well most of the time, but not always, and the problem is that it's not very predictable about it either. That means that you can't really be confident if you're "holding it right".

The biggest problem though, is that Windows is not really designed to be finger friendly. Yes, you can swipe in from the right and enter tablet mode. This is great if all you're trying to do is use the Surface Pro 4 as a tablet - but when you're trying to use it as a laptop but with a touchscreen, things start to fall apart. The default size of text and apps when you start the Surface Pro 4 is set to 200 percent. The first thing you're going to want to do is go to display settings and change this to 250 percent - if you're primarily using the device as a laptop. That's because although the text is fully readable at lesser magnification as well (thanks to the sharpness and clarity of the screen) it's a lot more comfortable at 250 percent. Unfortunately, a lot of the UI elements are still not easy to use with your fingers at this point. At 300 percent, this is less of a challenge, but then the amount of usable space you have on your screen gets quite limited.

Similarly, when you're trying to copy and paste text, or move files on your computer, you're really better off just plugging the keyboard in and using that or the trackpad - the touchscreen is just too limited. Of course, you can argue that this is why you have the keyboard in the first place. But it means that you can't really seamlessly move between the comfort of using a tablet, and the productivity of using a laptop, and the issue isn't the superb hardware, but Windows in its current form.

One of the main reasons laptops even exist is because they're portable, which means that they run off battery power as needed. If you're the type of laptop user who shuffles from meeting to meeting or to several different locations with your computer tucked under your arm, battery life is a serious concern. Somedays it's not easy to predict when the next chance to plug-in will arise, which makes battery life an important part of any laptop discussion.

The power required to push a QHD or 4K display is higher than that of a vanilla HD screen, which naturally leads to a decline in battery life. In our review of the MSI GS60 Ghost Pro 3K gaming laptop, which is actually a 3K machine, we lamented its lackluster battery life. In our tests, the battery went flat in just over two hours. In fact, poor battery performance seems to be the common thread among the laptops we've reviewed. The Toshiba Satellite P50T only lasted 2 hours and 40 minutes on battery, and its power-saving screen-dimming feature while on battery makes the computer virtually unusable outdoors.

Pushing more pixels in a display isn't the only added stress on battery life. The power necessary to output such pixel-packed visuals means most high resolution laptops require discrete graphics cards rather than integrated graphics. The need for a dedicated graphics card means the computer will naturally require more power than a laptop with integrated graphics. As laptop manufactures pack more and more pixels into their screens, the question of "is it worth it?" arises. In most cases, an Ultra HD laptop will look absolutely gorgeous, but that doesn't translate to it being useful. There are some serious trade-offs, including price, a lack of 4K content and performance that need to be considered before spending the money to move beyond 1080p.

On a day to day basis, the Surface Pro 4 proved to be up to just about any tasks that a journalist has - which is admittedly not a very draining experience, though we did manage to run Photoshop just fine. Opening dozens of Chrome tabs, editing PDF files, and simultaneously working on a Word and Excel documents while listening to music the whole time was perfectly smooth. That's simply not possible if you're using an Android or iOS based device. We were doing this while also transferring photos from a USB drive we'd plugged in, and there was absolutely no slowdown, and no awkward issues of hopping around from app to app - everything was just going on all the time in front of us, and we could pick and choose what we needed to do, when we needed to do it.

Also, it's worth noting that while the Surface Pro 4 does heat up when you're using it, this never gets unbearable even when you're doing something like gaming. The one area where the performance is disappointing is battery life. We've seen some people claiming 7 to 9 hours of use on a full charge, but that's not been the case in our own experience. With the suggested settings for the battery management and brightness, we typically got up to 6 hours of use on the battery. The Battery Eater Pro test (which shows the minimum battery life under heavy use conditions - your actual usage will last for longer than this) lasted for 1 hour and 32 minutes. And running the standard video loop test we use for mobiles, the Surface Pro 4 lasted only 5 hours and 35 minutes.

When you're gaming or going something else that's battery intensive, you simply have to plug in the Surface Pro 4. It's a far cry from other tablets which give you a lot more backup. In terms of performance though, this machine is quite capable even if it isn't a powerhouse. The top end model can definitely be used for gaming; the 4GB RAM in this entry level model is a little more limiting, however benchmarking tests showed that it's not too bad either. The POVRay benchmark took just over 7 minutes, while the CineBench R15 CPU Multi score was 206. PC Mark scores for Home, Creative, and Work (all accelerated) were 2,782, 3,608, and 3,677, respectively.

These are reasonably good numbers and since the computer is powerful enough for most office work, we tested the performance of a number of different games. We quickly learned that running current game at high settings is a bad idea as they're pretty unplayable. However, with a few tweaks, there are a lot of games that you can play on the Surface Pro 4.
