IT168 evaluation Today's smart phone product life time has gradually become a condition of concern to everyone when buying, for most mobile phone enthusiasts now, carrying a mobile power for mobile phone charging has become their daily life, and Many people also develop the habit of spending a day on the phone. Last year, Lenovo introduced a mobile phone P1 with a long battery life. The large-capacity battery and one-click power saving feature are all great highlights. Recently, Lenovo released the second generation of this product, the Lenovo P2 mobile phone. In terms of details and experience, there has been a certain degree of upgrade, there has been an increase in the battery capacity, and the energy consumption of the mobile phone has been reduced to a minimum from both software and hardware aspects.
From the hardware parameters, this phone basically uses the standard configuration of the mainstream 2000 thousand yuan file phone. Its biggest bright spot is the large battery capacity of 5100mAh. Currently, the mobile phone products with such a large-capacity battery in the market are actually rare. In terms of the duration of battery usage, it can theoretically be more than 1 times that of ordinary mobile phones. This is an important point for heavy users of mobile phones and users who often go out for activities. In addition, in terms of other parameters, the phone's configuration is quite satisfactory, Qualcomm Snapdragon 625 processing with 4GB running memory performance, smooth enough to cope with daily multi-tasking and 3D games. At the same time, the features of pre-fingerprint identification, dual-card dual standby, and 4G-compatible full-network can cover the basic usage requirements of all users. In general, the Lenovo P2 is a very practical mobile phone.

Looking at the hardware parameters alone is far from being able to locate a phone in the end. After all, the current configuration of mobile phones at the same price tends to be assimilated. Being able to make your own characteristics will attract users. Then let's take a look at Lenovo P2 in the appearance and system of the two related evaluation content.
Appearance Lenovo P2 uses an integrated metal body design, compared to the plastic back cover, for the improvement of texture is very obvious, and the metal body is now the mainstream. The dual CNC cutting process adds some refinement to the product. In the thickness of the fuselage compared to the previous generation of P1 has also become thinner. The thinnest point of official data is only 8.2mm.
The front design of Lenovo P2 is very simple. The pure black panel hides the front top distance sensor and light sensor, hiding the opening looks more concise. The front camera is placed on the right side of the handset with a maximum effective pixel of 5 million.
Lenovo P2 uses a 5.5-inch Super AMOLED full HD display, Corning 2.5D arc glass, 100% NTSC color gamut, up to 550nit brightness. The Lenovo P2 also used three virtual buttons at the bottom of the screen. The user is more convenient when using it. However, the design is also disadvantageous. When the program is opened, the buttons will occupy some of the screen below.
Lenovo P2 uses a rectangular Home key design under the positive panel. The fingerprint recognition module is combined with its Home key. A slightly convex metallic ring is added around the keys. The material of the key surface is the same as the panel. For glass, improved durability. The touch and long press of this key also enables you to return and return to the main menu.
It is worth mentioning that, as a flagship product, the Lenovo P2 has designed a power-saving switch, placed in the middle of the left side of the fuselage middle frame, and can turn on the limit power saving mode in one click. Damping feel is still pretty good, when the left hand is holding one hand, you can use the thumb toggle switch to open a key power saving mode.
In the power-saving mode, Lenovo P2 also supports the use of some conventional applications, supports WLAN data connections and applications such as WeChat, QQ, Weibo, music, and e-books to meet users' basic needs in everyday life. And the phone also supports WeChat / QQ application dual-open function.
Lenovo P2's eXetremeCOMM intelligent communications enhancement system designed for business scenarios supports 7-mode and 21-band signaling, which basically covers the global network standard signal and is a true Netcom product. In addition, Lenovo P2 supports dual card dual standby, one of which can be inserted into the TF card. Both card slots are Nano models.
In terms of cameras, the P2 has also been upgraded with the previous generation of products, using the Sony IMX258 stacked camera, 1300W main camera +F/2.2 aperture, 0.2S PDAF phase focus, camera functions to meet the general user needs. We can also see that the aircraft also supports NFC functionality, UnionPay HCE mobile payment. At the same time support Alipay, WeChat fingerprint payment.
Let's continue to take a look at some of the system aspects of the Lenovo P2 mobile phone. Lenovo P2 uses VIBE UI 3.5 based on Android 6.0 this time. To be honest, the system does not have any outstanding features for everyone. Compared with the previous generation of P1 UI, it can be said that it is simplified a lot, it can be said It is easier to use.
The Lenovo P1 mobile phone is powered by the VIBE UI3.5 system based on the Android 6.0 platform. Its default theme is also similar to Google's native operating system. Practical and simple to use. In the drop-down menu, VIBE UI is also borrowed from the design style of Google's native system, and can be customized shortcut function keys, allowing users to easily use in the use.

Relative to other mobile phones, VIBE UI's multitasking management interface is a bit too concise. The basic copy of the native Android style, although there is a button to clear the memory button, but the remaining amount of running memory is not marked. This may not have any effect on the average user, but for some mobile phone enthusiasts, it is not very comfortable to accurately view the remaining RAM. Fortunately, some additional tricks can be solved by installing plugins or applications.
The Security Center and Lenovo Calendar are featured applications of the VIBE UI system. The former includes a variety of use features, such as: traffic monitoring, rights management, application management, harassment interception, background management, power management, space cleaning, mobile security, privacy mode. The privacy mode is one of my favorite functions. The user can set another pattern password. When you use this pattern password to unlock the screen, it will automatically enter the privacy mode. The advantage of this is that when someone wants to play with your phone, you can let the phone silently enter the privacy mode. In this mode, you can hide the pictures, videos, contacts, applications and other information in advance, which can prevent important information from leaking. .
In addition, the Lenovo calendar has more than the traditional calendar software except for the lunar calendar and holidays. You can also automatically add contact birthdays, credit card repayment dates, and more. Smarter, users can also subscribe to lottery lottery dates and multi-city single-double dates, which is very convenient.
The biggest highlight of VIBE UI3.5 is ease of use and simplicity. However, there is still room for improvement in the unification of system interfaces. Comparing with the current situation of domestic contending, it still has strong competitiveness. Hope that Lenovo will be able to make the UI more perfect in future software upgrades.
With the rapid development of the mobile phone industry, the camera's camera function has a tendency to catch up with ordinary cameras, and it has unique advantages in terms of portability and ease of use. Therefore, more and more users will give priority to how their imaging effects when purchasing a mobile phone. Here we take a look at Lenovo P2 this phone can meet our daily shooting needs.
Lenovo P2 mobile phone camera evaluation
Lenovo P2 mobile phone uses a 13 million-pixel main camera, and both have phase focus function, compared to the traditional contrast focus, the focus speed is very obvious, the official data said, can achieve 0.1 seconds of rapid focus. It is worth mentioning that the camera also has a very useful feature - open screen shots. As its name implies, its greatest feature is that it can take pictures quickly and quickly when the screen is turned off. When the user encounters the need to capture the situation, you can directly take out the phone, without lighting the screen, double-click the volume button + or volume - directly, you can take pictures directly. However, in this case, since the display on the screen cannot be seen, the result of the photographing may not be ideal, and the virtual focus condition may easily occur.
In the normal photo mode, the user can adjust the white balance, ISO options, and metering methods to change the imaging effect. However, taking into account the daily user's habits, this time the proofs were all shot in the automatic mode, without any post-processing other than cutting.
Lenovo P2 mobile phone camera evaluation
First of all, let's take a look at the resolution of the photos taken by Lenovo P2 mobile phones. After the details of the image are enlarged by 100%, we can still clearly see the details of the building. So clearly showing the details of the photos, but also mainly rely on its main camera 13 million pixels. In addition, for the grasp of white balance, Lenovo P2 is still in place. When the light is bright, the photos taken can be very accurate to restore the actual color. Let's take a look at the other proofs shot on this phone.
Although the camera ability is not regarded as the main selling point of the P2. However, we can see from these proofs, with the Lenovo P1 mobile phone in the case of adequate light during the day, the photos taken can very well restore its original color, while its background blur effect is still OK. Image quality is still relatively high. However, in the case of insufficient light at night, the imaging effect of the phone is not ideal. To prevent glare, it had to sacrifice the brightness of the photo. Although this approach reduces noise, many details of the photo will be covered in black.
Although Lenovo P2's comprehensive camera capabilities can not be compared with the current flagship mobile phone, but in the same price of the mobile phone, it can be regarded as a medium-side. In addition, the phase focusing technology also adds a lot of points to it, and it really does a lot faster on the focus speed than the ordinary contrast-focused ones. However, for the average user, Lenovo P1 can fully meet the needs of daily shooting.
