Comparison Meizu M8 64 GB vs Meizu M6s 64 GB

The term “operating system” in this case refers to all types of firmware — both full-fledged operating systems such as iOS and Android used in smartphones, and software platforms for regular phones (non-smartphones). The main difference between these two categories is that a full-fledged OS initially has a more extensive set of functions and also allows users to install and remove various applications — from games and social media clients to specialized tools such as photo and video editors.

Among modern smartphones, two operating systems are the most widespread — Android and iOS. Here is a more detailed description of each:

— Android. A free open-source OS by Google. It is used by almost all modern manufacturers except Apple; it is available on the market in numerous versions — in particular, the current ones are Android 14, Android 15, Android 16, Android 17. It should be noted that one OS version may have been installed when the device was released, while by the time of sale it may have been updated to a newer one. Functionally, this OS is notable primarily for full multitasking support and an extensive selection of available apps — in both respects, it surpasses iOS; on the other hand, Android apps generally have somewhat lower quality due to less stri...ngent requirements. Android initially has close integration with Google services — the Google Play app and content store, Gmail email, Google Drive cloud storage, etc.; however, exceptions to this rule are possible. Note that the latest versions of this OS can be found on the market both in their original form and in one of two specific editions:

• - Go Edition. A modification of Android designed for affordable smartphones with “weak” hardware. Both the OS itself and standard apps (Assistant, Gmail, etc.) have been redesigned in this edition to ensure reliable operation even with low processing power. At the same time, developers have tried to preserve the functionality of full Android as much as possible — nevertheless, some specific features are still unavailable in Go Edition (for example, standard maps do not support turn-by-turn navigation, and compatibility with the Wear OS system on smartwatches is not provided).
• - HMS. An edition of Android used in Huawei smartphones. Due to US sanctions against China, this company cannot fully cooperate with Google — in particular, it cannot use Google services (Google Mobile Services — GMS) in its Android smartphones. HMS — Huawei Mobile Services — was introduced as a replacement. These services include a Huawei ID user identifier, the AppGallery app store, proprietary equivalents of Google's main services (assistant, browser, cloud storage, music/video, etc.), as well as tools for app developers.

As for individual Android versions, here are the main features of its variants:

• - Android 13. A popular operating system for mobile devices, the 13th version of which was released in 2022. No radical innovations were implemented in Android 13, but the OS introduced a number of useful features and changes. In particular, the Material You workspace design concept can now select primary colors from installed wallpapers or themes and apply them to icon display throughout the system. User data privacy has reached a new level — Android 13 allows configuring individual permissions and selecting specific images from the Gallery that an app can access. Users can choose the default interface language for each program. The system has also become more energy-efficient, while the clipboard and barcode scanner have been improved.
• - Android 13 Go. A lightweight version of the Android 13 operating system designed for installation on low-power smartphones. A distinctive feature of the OS is a special algorithm that optimizes the smartphone's processing power. The system also lacks some hardware-demanding functions. Android 13 Go introduced the Material You interface design concept, allowing the menu color scheme to be adapted to the installed wallpaper. The Go version inherited from the full Android 13 system the ability to grant apps permission to send notifications and the option to change the language for specific programs.
• - Android 14. An operating system for mobile devices released in 2023. Frankly, there are few system changes in the 14th version of Android, with the main focus placed on flexible interface customization. Among the new features, it is important to mention notification display via the flash or screen: a flashlight blinking pattern can now be set for each app, while a color palette for notifications can be selected for the screen. The operating system also introduced a useful option for adjusting screenshot capture, added a widget for displaying battery charge and a list of active connections, and implemented a system-level app cloning option. System fonts in the OS can be increased up to 200% of their standard size, with non-linear scaling — it is primarily applied to small text. Other improvements include enhanced system energy efficiency and cosmetic interface changes with more rounded elements.
• - Android 14 Go. A lightweight version of the Android 14 operating system for budget smartphones with limited hardware resources. The Go Edition distribution includes simplified standard apps while providing basic Android functionality with minimal performance and power consumption requirements. Despite its “lightweight” nature, Android 14 Go supports improved notifications, new controls, and privacy settings that debuted in the full 14th edition of Google's OS. However, smartphones with the lightweight Go version are not compatible with Wear OS smartwatches — this should be taken into account.
• - Android 15. The Android 15 operating system was released in 2024. Notable innovations include native support for satellite communication (for contacting emergency services or sending SOS signals), the ability to record and share only a specific app window rather than the entire screen, updated hardware extensions for camera control, enhanced control over messages, and flexible volume adjustment. The system has also traditionally received improved security features and increased energy efficiency.
• -Android 16. The 2025 version, where one of the main innovations is Live Updates dynamic notifications — they show delivery progress, trip status, or another process without requiring the app to be constantly opened. The system also automatically groups notifications from the same app, received an enhanced Advanced Protection mode, and improved hearing aid controls.
• -Android 17. The next generation of Android was officially released on June 16, 2026. The main focus is on multitasking: apps can be opened in floating Bubbles windows, quickly switched between, and expanded to full screen. It introduced improved screen recording with user reactions, an optimized gaming interface for foldable devices, and external controller button remapping. The system also received stricter access control for location and contacts, enhanced stolen smartphone locking, and memory management to improve stability and battery life.

— iOS. Apple's proprietary operating system, used only in this manufacturer's gadgets. The main advantages of iOS over Android are primarily careful optimization for specific devices (allowing good performance with relatively modest RAM capacities), overall ease and security of use, as well as high app quality. In addition, iOS updates are released regularly and are available for all devices (except clearly outdated ones that can no longer handle new system versions). On the other hand, this OS does not support multitasking and is as closed to the user as possible: in particular, apps can only be installed from the proprietary store, there is no access to the file system, and memory cards are not supported in principle.

— Harmony OS. A universal operating system by Huawei, also known as Hongmeng. It supports a wide range of devices: smart home ecosystem equipment, smartwatches, smartphones, and tablets. Harmony OS is a kind of overlay on top of Android without Google services. The app store for devices running Harmony OS is called AppGallery.

— Flyme OS. A modified version of the Android operating system used as the software platform for Meizu smartphones. The OneMind engine is responsible for OS stability. Flyme OS has no app menu, and all program icons are distributed across home screens. Distinctive features of the platform include advanced file management tools, the Aicy voice assistant, flexible mEngine vibration adjustment, Family Guardian parental control options, and a structured gallery with a convenient visual editor.

— Proprietary. This term most often refers to basic firmware installed in a regular phone (not a smartphone), usually a button phone. Such firmware has a more modest set of pre-installed programs than full-fledged operating systems; at best, this set can be expanded with universal Java-based mobile apps, while additional apps are often not supported at all. However, this cannot be called a disadvantage, given the specifics of traditional phone use.

Note that devices with other operating systems besides those described above can also be found on sale. However, most of these are either outdated models or devices with rare and uncommon types of firmware.

The ratio of the screen area to the total front panel area of the phone. Simply put, this spec describes how much of the front panel is occupied by the screen; the rest is the bezels.

This indicator is given exclusively for smartphones with touch screens — it is for them that it is most relevant. The larger the percentage of the body is occupied by the screen, the thinner are the bezels, the neater the smartphone looks and the more convenient it is to work with it with one hand. As for specific numbers, the average values are 80 – 85 %, the higher values allow us to talk about a thin bezel, and more than 90 % — about a “bezel less” design.

Separately, we note that this parameter has nothing to do with the aspect ratio of the screen. The aspect ratio describes only the display itself — its proportions, the ratio between the larger and smaller side of the rectangle.

The number of cores in the processor of a mobile phone.

The core in this specific case refers to the part of the processor that executes one thread of commands. Accordingly, the presence of multiple cores allows you to work with multiple threads simultaneously, which has a positive effect on performance. At the same time multi-core CPUs are now found even in the most inexpensive modern smartphones — even chips with 8 cores are not uncommon among them, not to mention simpler quad -core and six-core solutions. And some modern processors can have up to 10 cores.

Theoretically, more cores can improve processor efficiency. However, in fact, the performance of the CPU (and the smartphone itself, eventually) depends on many additional factors. Thus the number of cores is purely a reference parameter. For example, a high-end quad-core processor may be much more performant than an inexpensive eight-core one. So you really should focus on overall level of performance and the results shown in various tests (see below)

It is also worth mentioning that individual cores of mobile CPUs may vary in clock speed, performance and power consumption. The classic version is 8 cores working according to the “4 + 4” scheme: 4 relatively “weak” and power efficient cores are responsible for simple tasks like Internet surfing, and ano...ther 4 – more powerful ones - turn on when high performance is required (for example, in games with advanced graphics). This scheme of work allows you to achieve the optimal balance between performance and energy efficiency of CPU.

The parameter determines the overall performance of the smartphone: the more RAM, the faster the device works and the better it copes with an abundance of tasks and / or resource-intensive applications (ceteris paribus). This is even more true in light of the fact that large amounts of "RAM" are usually combined with powerful advanced processors. However, only devices with identical operating systems can be directly compared with each other, and in the case of Android, with the same versions and editions of this OS (for more on all this, see "Operating system"). This is due to the fact that different operating systems and even different versions of the same OS can differ markedly in terms of RAM requirements. For example, iOS, thanks to good optimization for specific devices, is able to work efficiently with 3 GB of RAM. For modern versions of Android in the regular edition (not Go Edition), the mentioned 3 GB is actually the required minimum. Under such an OS, it is better to have at least 4 GB or 6 GB of RAM. In high-end devices with powerful electronic "stuffing" you can also find more impressive numbers - 8 GB or even 12 GB or more.

The test results are specified either by a younger model in a line or a particular model, made for a better understanding performance of phone models if you compare phones against these parameters. For example, the 128 GB model has test results, and the 256 GB model has no information on the network, and in both models you will see the same value that will give an understanding of the overall performance of the device. But if the editorial office has information for each model individually, then each model will have its test results filled out, and the model with bigger RAM will have bigger values.

The result shown by a device when undergoing a performance test (benchmark) in AnTuTu Benchmark.

AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It evaluates the efficiency of the processor, memory, graphics, and input/output systems, providing a clear impression of the system's capabilities. The higher the performance, the more points are awarded. Smartphones that score over 1.5M points are considered high-performance according to the AnTuTu ranking.

Like any benchmark, this test does not provide absolute precision: the same device can show different results, usually with deviations within 5-7%. These deviations depend on various factors unrelated to the system itself, such as the device's load from third-party programs and the ambient temperature during testing. Therefore, significant differences between two models can only be noted when the gap in their scores exceeds this margin of error.

The result shown by a device when undergoing a performance test (benchmark) in Geekbench.

Geekbench is a specialized benchmark designed for processors. Since version 4.0, it also includes tests for graphics processors, and by the end of 2019, version 5 of the benchmark was released. Typically, the specifications for portable gadgets include data specifically for the CPU. During testing, Geekbench simulates workloads that occur during real-world tasks, evaluating both single-core performance and the efficiency of multi-core operations. This provides a solid overview of the processor's capabilities in everyday use. Additionally, Geekbench is cross-platform, allowing for comparisons between the CPUs of different devices (smartphones, tablets, laptops, PCs). In reference materials, only the multi-core test results for the processor are usually provided.

The result shown by the phone in the 3DMark Sling Shot Extreme (OpenGL ES 3.1 / METAL) test.

3DMark is a series of tests originally designed to check the graphics part of the device for performance; later, tests for CPU and memory capabilities were added. Specifically, Sling Shot Extreme is one of the latest versions of 3DMark, released in 2016 aimed at powerful high-performance devices and gaming smartphones, for which earlier tests were insufficient. One of the key features of the test is support for resolutions up to 2560x1440 (predecessors did not exceed a maximum resolution of 1920x1080, and sometimes even 1280x720). Furthermore, in accordance with the name, the test supports OpenGL ES 3.1 specifications (for Android) and Metal API (for iOS), used in modern mobile video chips; and from mid-2019, it also includes support for 64-bit processor architecture. Thus, 3DMark Sling Shot Extreme allows for an accurate assessment of even the most powerful and advanced modern smartphones. The evaluation is traditionally indicated in points, the more points — the better the result.

It should be noted that the results of any benchmark are usually quite approximate, as they depend on many factors not directly related to the system. The error conditioned by these factors usually amounts to about 5 – 7%; therefore, a substantial difference between two models can only be discussed if the difference in their scores exceeds this margin of error.

The number of individual lenses provided in the module of the main (rear) camera of the device. Specified only if there are several lenses. At the same time, each «eye» has its own sensor and, in fact, is a separate camera; however, they can be used in conjunction, forming one image from data from several lenses, or mutually complementing each other's capabilities. As an illustration of the second case, the following example can be given: when using the zoom, the smartphone can automatically switch from the main optics to the telephoto lens when the magnification selected by the user exceeds a certain threshold.

The simplest version of the main module with several lenses is a dual camera, however, devices with 3 or more rear cameras are becoming more common (in some models, the number of lenses can reach six). Anyway, these cameras usually differ in specifications and perform different functions. So, an ordinary colour camera can be supplemented with a lens for black-and-white shooting, which improves contrast; in some models, lenses with different focal lengths allow you to choose the optimal viewing angle for certain conditions; information from an auxiliary lens (see below) is usually used to adjust the depth of focus on an already finished shot, etc. These details should be clarified separately, but anyway, several lenses mean more shooting options.
