Samsung Galaxy M31s 6/128GB

Samsung Galaxy M31s is a step above the Galaxy M21, although the battery capacity remains unchanged - the same 6000 mAh, which is charged by fast charging.

It uses an excellent 6.46-inch matrix with a resolution of 2400x1080 pixels, the familiar Samsung Exynos 9611 chipset of its own production, 6 GB of RAM and 128 GB of ROM. The fingerprint scanner has moved from the back cover to the side power button. Why this was done in the presence of an AMOLED screen is unclear.

While the Galaxy M21 has a triple main camera, the Galaxy M31s has a quad camera. I must say that the main module takes better pictures.

Good cameras
Clean, minimal software

Minuses

No wireless charging

The Asus Zenfone 8 may not match the battery life of its predecessor, but it still clocks in at a solid one minute less than the OnePlus 9, and it's also the smallest flagship Android phone on the market to deliver impressive battery life.

It allows one-handed use, which can't be said about any other Snapdragon 888-powered phone. But the Asus Zenfone 8 has some compromises, it lacks a telephoto lens and full 5G support, but compared to price and performance, these are minor compromises depending on your needs. needs.

BQ 5535L Strike Power Plus

We won’t lie: a 5000 mAh battery is far from a record in the world of mobile technology today, but the BQ 5535L Strike Power Plus is interesting because it combines quite expensive functions at a low cost. Which? Of course, a 5000 mAh battery, a fingerprint scanner and even an NFC module.

Honor 10X Lite

A fresh smartphone from Honor, equipped with a 5000 mAh battery with support for fast charging.

However, experts note that this is not the main thing - what is more important is the camera, which is surprisingly good for its segment. We would like to thank the following modules: main, wide-angle, macro and depth sensor. There is support for night mode.

A relatively large display with a diagonal of 6.67 inches with a high resolution is installed, there is NFC, and the Hisilicon Kirin 710A is used as a chipset, which is paired with 4 GB of RAM.

Minuses

Not the best cameras in the class

Based on testing results, the OnePlus 9 Pro is currently the most powerful Android phone on the market and one of the few Android phones that beats any of the iPhone 12 models. And although it lags behind the ROG Phone 5 when it comes to maximum battery life at 60 Hz, it actually pulls ahead when you compare them side by side at 120Hz. This is all the more impressive considering the OnePlus 9 Pro's 4,500mAh battery compared to the ROG Phone 5's 6,000mAh battery.

The OnePlus 9 Pro is also a much more advanced device than the ROG Phone 5, with cameras that are at least competitive with the best from Samsung and Apple, even if they are still a little behind in some respects. If you're looking for a flagship phone with the best battery life from a company other than Samsung and gaming isn't your only goal, the OnePlus 9 Pro is your best bet.

Xiaomi Poco X3 NFC 6/128GB

Many experts call Poco X3 NFC one of the most successful smartphones of recent times. Why?

The word NFC in the name speaks for itself. But if an NFC sensor doesn’t surprise anyone in this class today, stereo sound and splash protection are rare. And the design is gorgeous, you can see the case yourself in the image below.

As for the battery, its capacity reaches 5160 mAh, of course, there is fast charging. An excellent 6.67-inch diagonal screen is installed, and the main camera with 4 modules takes very good pictures.

Which phone with fast charging function should you choose?

Our review contains all the best smartphone models with fast charging functionality. We tried to take into account the wishes of all consumers by adding affordable smartphones and top solutions to the TOP, the best among which is the current flagship of Apple. If you need something more affordable, but with an NFC module, we recommend Xiaomi. A smartphone from the Highscreen brand will offer a little more power at a lower price, but in this case you should carefully look at the modification so as not to accidentally purchase a version without an NFS chip.

OPPO A53 4/64GB

The characteristics of the OPPO A53 are unlikely to impress anyone, but only until you see its cost: here you have 90 Hz support, a 5000 mAh battery with fast charging, and an NFC sensor. The case design is also very good.

It uses a 6.5-inch matrix with a resolution of 1600x720 pixels, a new Qualcomm Snapdragon 460 processor with 8 cores, 4 GB of RAM and 64 GB of ROM.

Camera? There is a triple camera, but nothing special stands out.

ZTE Blade 20 Smart

Here you have a cool body design, a high-quality 6.49-inch display, a very vigorous platform based on the MediaTek Helio P60 chipset and 4 GB of RAM, and a powerful 5000 mAh battery with fast charging.

Experts note the camera: if the main module takes good pictures, then the wide camera is better than many more expensive smartphones.

Xiaomi Redmi 9A 2/32GB

Xiaomi Redmi 9A is a budget smartphone, one of the most inexpensive in the company's lineup.

You shouldn’t expect incredible characteristics from it, everything is quite simple, but at the same time not bad: a good 6.53-inch matrix, a good MediaTek Helio G25 chip, which works together with 2 GB of RAM, two regular cameras (front and main), which normally removed, as well as a 5000 mAh battery.

There is no fast charging, as well as a scanner or NFC sensor, but there is a face unlock function.

Samsung may not match Apple's battery optimization software, but it makes up for it by putting larger batteries in its phones—and it works, too. In fact, among the current generation, Samsung phones are on average ahead of their iPhone counterparts, unless you turn off 5G on Apple phones.

Galaxy phones can't match the performance of the iPhone, but they have a lot of other features besides battery life. In the Galaxy S line, you have massive zoom capabilities on the Galaxy S21 Ultra's camera, stunning 120Hz AMOLED displays, and incredible Windows 10 integration.

Samsung also makes some of the most unique smartphone offerings available today, such as the Galaxy Z Fold 2 and Galaxy Z Flip 5G, which have significantly better battery life than their direct competitors. Finally, for stylus fans, there's the Galaxy Note 20 Ultra, one of our favorite phones of 2022 and possibly the last Galaxy Note we'll ever see.

A budget smartphone from Honor, although you can’t tell from its appearance.

realme C11 2/32GB

And another budget phone, only this time from the already well-known company realme.

This model uses a powerful battery with a capacity of as much as 5000 mAh, but since we are talking about an inexpensive model, fast charging is not provided.

The smartphone has a very stylish body (the inscription on the back cover alone is worth it), a 6.5-inch screen, and even a good platform for its segment based on the MediaTek Helio G35 chipset and 2 GB of RAM. Built-in - 32 GB, can be expanded via a memory card slot.

Alas, there is no fingerprint sensor, but, as far as we know, it is replaced by the face unlock function.

Xiaomi Mi 10T Pro 8/256GB

Xiaomi is expanding its model line. Meet Mi 10T Pro - a slightly simplified version of the flagship Mi 10 model.

Here you will find a completely different design of the rear panel, a new 6.67-inch IPS screen, not AMOLED, which at the same time supports a refresh rate of as much as 144 Hz, a new main camera - it takes pictures, of course, easier than the flagship, but at a decent level .

pros

Super fast charging
Crisp, smooth 120Hz screen
High performance

Minuses

No microSD card slot

The OnePlus 9's price makes it more of an upper-mid-range phone than a flagship. It's also pretty close in performance to the OnePlus 9 Pro, given the same 4,500mAh battery and Snapdragon 888 processor. The OnePlus 9 actually lasted 31 minutes longer with 120Hz mode enabled, which is a big difference from the OnePlus 8T, which there is a significant hint of a higher refresh rate. Like the OnePlus 8T and OnePlus 9 Pro, it offers 65W fast charging with a charger in the box and, unlike the OnePlus 8T, it also supports wireless charging.

It loses several key features of the OnePlus 9 Pro, such as Sony's new IMX789 primary wide-angle sensor, 3.3x telephoto lens, and 120Hz adaptive display. However, it has an identical 50MP ultra-wide-angle sensor and the same new Hasselblad color technology applied to its cameras, which has impressed us so far. If photography and videography are less important to you, the OnePlus 9 is otherwise nearly identical to its more expensive sibling.

Samsung Galaxy A21s 3/32GB

Samsung even installs quite powerful batteries in many of its inexpensive smartphones. One example is the Galaxy A21s, which received a capacious 5000 mAh battery with support for fast charging.

In many ways, this model is similar to the older Galaxy A series smartphones, but there is no AMOLED screen (TFT PLS technology is used), and the processor is far from the most powerful Samsung Exynos 850. At the same time, the design is 100% recognizable. This particular version has 3 GB of RAM and 32 GB of internal memory.

The camera received 4 modules. It takes good pictures, but you shouldn't expect miracles.

Battery size and life

Battery size or capacity , usually measured in milliamp hours (mAh), refers to the amount of energy a particular battery can store. Simply put, the higher the milliamp hours (mAh), the longer the battery lasts. So if battery life is important to you, choose a battery with at least a 4,500 mAh capacity.

Battery life is also important. Please note that battery life and operating time are two completely different factors. While runtime defines the period from one charge to the next, runtime refers to the number of charges a battery can handle before its capacity drops to an unacceptably low level. In light of this, if you need a quality battery, choose a battery with a minimum lifespan of 300 charges.

Does this mean that the larger the battery and the longer its lifespan, the longer the battery will last? In an ideal world this would be yes. But, there are several variables involved. One such variable is the display. If your phone has a larger screen, it requires more power to operate and therefore consumes more battery.

Display and chipset

If a smartphone has a small display but high resolution, it will have more pixels, therefore requiring significant processing power, and will drain the battery faster. For example, if you have a fully charged smartphone with a 3000mAh battery and 1440P resolution, and your friend's phone has the same battery but with 1080P resolution, your phone will die faster.

Apart from the display, the chipset is another variable that affects not only the battery life but also the performance of the smartphone. Rule of thumb: the newer the chipset version, the higher its performance and lower power consumption. For example, the Qualcomm Snapdragon 855 chipset is faster and more power efficient than previous versions.

Therefore, if you want to get a phone with maximum battery life, you need to consider not only the capacity and life of the battery, but also the characteristics of that particular model.
