Review of the product design of the vivo Y91i

Rating of the ease of carrying it around and getting it in and out of bags or pockets

When deciding whether to buy an vivo Y91i, the first important factor is its size. Smartphones are used daily, and so it is important how easily they can be carried around and pulled out of bags or pockets. This review assesses how easy it is to carry the vivo Y91i around and put it away.

Ease of grasping it in your hand to carry around

The vivo Y91i is easily held with one hand, and its size allows it to be firmly held. It is small enough to be held in one hand together with things like a wallet, but this may be a bit difficult for ladies with small hands.

Ease of carrying it around when placing it in your pocket

It doesn't feel strange even when you put the vivo Y91i in a pocket. In addition, when sitting on a chair with the phone in a pocket, it can be kept comfortably as it doesn't get caught on one's clothes or body.

Ease of getting it in and out of your pocket

Sometimes taking the vivo Y91i out of your pocket doesn't go so well as it gets caught on fabric easily. It's safe to assume that some people will find it stressful that it is difficult to take it out smoothly.

Ease of getting it in and out of your bag

The vivo Y91i is a size that allows you to take it in and out of your bag and use it with ease. Also, since it is compact, even if your bag is small it won't get too bulky which is convenient.

Assessment of user-friendliness and ease of handling

It is important to consider the ease of using the phone in one hand. It can be said that it would be very useful if it is easier for you to send emails and instant messages or answer calls using one hand while cooking or using your computer. Here, we have reviewed the vivo Y91i by focusing on the ease of using it in one hand and the ease of typing in letters.

Ease of grasping the phone in one hand

The vivo Y91i is a size that allows you to have a firm grip even while using it. Since your hand is kept stable, it is difficult to accidentally drop the phone, and it is very easy to use. Since the original body size is small, the phone is still easy to hold even when using a case.

The weight you feel when using the phone with one hand

The vivo Y91i is a slightly heavy smart phone so using it with one hand for a short period doesn't cause any pain, however when used for long periods continuously it can hurt your hand. If you add a case and accessories it feels even heavier. It is preferable to use the phone with two hands and a proper case.

Ease of pushing the upper button on the screen using one hand

When using the vivo Y91i with just one hand, it is quite difficult to press the button on the screen edge. We suggest you operate the device with both your hands rather than pushing your luck with just one hand.

The size of the buttons on the App

The buttons on the vivo Y91i are displayed quite large. Because of this, it is difficult to press something by mistake and it feels very easy to use. Even with games that use small buttons, it's difficult to press something by mistake making it very easy to play.

Ease of typing in letters using the flick function

Keys on the vivo Y91i can be pressed even when held with one hand, but your grip may weaken when trying to flick the buttons at the edges. As a result, it may become unstable in the hand when flicking quickly, but it won't be easy to drop as long as you are careful.

Ease of typing in letters using the keybord funtion

If you aren't being careful it is really easy to mistype when using the vivo Y91i with two hands since the buttons are so small. In addition, typing at high speeds is pretty difficult and I can't say its very suited for it.

Assessment of whether it is suitable for standard use

Assessment of whether it is suitable for standard use

For people who use their smartphone on a daily basis, high performance is a rather important factor. When the performance is not good enough, then, for example, applications don't work as they should or the screen is difficult to see, and this causes stress. This review looks at whether the performance of the vivo Y91i is suitable for making phone calls, messaging, or using SNS.

The size of the letters and the ease of operation

Because the display of the vivo Y91i is much larger than ordinary phones, characters are displayed quite large. Therefore, it is suitable for reading long bodies of text and exchanging long messages while doing research.

Ease of reading sentences

Since the vivo Y91i displays characters smoothly, it can display them beautifully. Even when viewing small characters, the jaggedness of the character outline is not at a level seen during normal viewing and is displayed very naturally. Because of this, it is difficult for your eyes to become tired and make the phone suitable for reading long bodies of text.

The beauty of the overal screen

The vivo Y91i can display photos and videos beautifully. While people with good eyes can see jagged outlines when they look at the display up close, it is not really something of concern.

Ease of writing sentences

The vivo Y91i has enough screen space even when typing and the screen is hidden by the on screen keyboard. Because the sentences being typed can be seen clearly, the phone's screen size makes it suitable for typing and editing large bodies of text such as office documents.

Does it have sufficient performance to make calls and send emails?

Whether it be a phone call, mail, or during a chat, the vivo Y91i provides smooth performance. Even when using the phone in demanding situations, you can use the phone comfortably since there will usually be no lag.

Does it have sufficient performance to search for things and using Social Networks?

It is more than adequate for applications such as using social media—like Facebook and Instagram—and searching the Internet. Sometimes, though, it may feel a bit slow.

Does it have sufficient performance to do other tasks while searching for things and using Social Networks?

There isn't any sense of inadequate performance even when several apps are used at the same time and there is frequent switching between apps. In rare cases, it may feel slow and the display may lag, but I don't think one will feel stressed during practical use.

Summary of vivo Y91i performance and functions

The size and weight of the vivo Y91i

The body of the vivo Y91i is 3.0 inches (75.1 mm) wide, 6.1 inches (155.1 mm) long, and 0.3 inches (8.3 mm) thick. Also, the screen size is 6.2 inch, and it weighs 163.5 oz (163.5 g). Compared to normal smart phones, it has quite an impressive size. It is easy to see and operate due to the large screen, but you can almost forget about using it with one hand. It is quite heavy and not really suitable for operating with one hand.

The battery life of the vivo Y91i

The vivo Y91i has a battery capacity of 4030 mAh. Compared to normal smart phones, it has quite a high-capacity battery.

The processing capability of the vivo Y91i

The vivo Y91i uses the Qualcomm SDM439 Snapdragon 439 CPU with 1.95GHz+1.45GHz×8(OctaCore). The memory capacity is 2GB. The CPU processing performance is average. This level of processing is perfectly fine for games and Internet searches. It is slightly lacking in terms of high-capacity processing such as 3D games, but there are no real issues for normal usage. It has the memory capacity of a standard smartphone. Having more capacity would make apps less likely to crash and make it easier to use, but the performance is fine for the Internet and emailing. For gaming, you would want the next level up in performance.

The camera of the vivo Y91i

The vivo Y91i has a back camera with 13 MP. The front camera has 8 MP. Its rear camera has slightly better performance compared to normal smart phones. While there are times when I feel it is lacking, it is able to take pictures with satisfactory quality almost all the time. The front camera performance is also roughly the same as a standard smartphone. The image quality for longer distance photography is less than satisfactory, but on the whole, there are no issues with short distance photos.
