Review of the Samsung Galaxy A51 smartphone. NFC, 4000 mAh

Haier Power P8

Display: 5.5 inches, 1280*640
Processor: MediaTek MT6739
Memory: 1/8 GB
Battery capacity: 4500 mAh
Operating system: Android 8.1

Price: from 4,000 rub.

Haier's budget smartphone is a device with its pros and cons. First of all, the device is worth considering for its autonomy - a large battery for a small screen and an undemanding processor provides at least 2 days of operation. The second positive point is that there is 4G for a modest price. It would seem that this cannot be attributed to the advantages, but even in the era of the advent of networks, some manufacturers manage to produce equipment without LTE. Another nice thing is the dual cameras on the back and front - 13+2 megapixels and 5+2 megapixels. Of course, their results are not top-notch, but they fully justify their price. There are some drawbacks - while the processor is still relatively good for a budget device, the memory of 1/8 GB is frankly not enough.

Advantages:

Excellent autonomy.
Dual camera front and back.
LTE support.
Separate slot for memory card.
Pure Android.
Very low price.

Flaws:

Large thickness – 10.8 mm.
Small memory set – 1/8 GB.
Slow to charge.

BQ 5514G Strike Power

Display: 5.45 inches, HD+
Processor: MediaTek MT6580
Memory: 1/8 GB
Battery capacity: 5000 mAh
Operating system: Android 8.1

Price: from 4,990 rub.

The budget new product from Haier looks more interesting against the backdrop and the key word here is “looks”. If the previous device suggests that it was released in 2015, then the BQ meets the requirements of modern times - thin frames, bright body colors, a fingerprint sensor on the back cover. At the same time, the model has a huge battery, but the thickness is 10.4 mm - this is a bit much, but less than that of Haier. In terms of tactile sensations and appearance, the smartphone as a whole is not bad, but the filling here is modest.

A minimal amount of memory and a weak chipset cope with undemanding tasks, but this is more likely due to the pure version of Android. The device does not have 4G - this is a serious disadvantage compared to the previous model. The rest of the device is standard - MicroUSB connector, long-term charging, 2 SIM cards, single cameras - 8 and 5 megapixels. The BQ 5514G is the choice of those who need looks and autonomy, rather than performance and fast browsing.

Advantages:

Modern appearance.
Not bad ergonomics.
Capacious battery.
Several body colors.
Good screen quality.
There is a finger scanner.

Flaws:

It takes a long time to charge.
Very little memory.
No LTE.

DOOGEE S40

Display: 5.5 inches, 940*480
Processor: MediaTek MT6739
Memory: 2/16 GB
Battery capacity: 4650 mAh
Operating system: Android 9.0

Price: from 6,400 rub.

Those users who are looking for not just something affordable with good battery life, but a smartphone that is reliable in any conditions can turn their attention to the Doogee S40. The model fully meets these requirements. It has full protection according to all standards: IP68, IP69K, MIL-STD-810G. It won’t break, won’t drown, and even in cold or hot weather it will work without any problems. In addition, there is a capacious battery - according to the manufacturer, it will last for 18 hours in games, and you can surf for more than a day.

The device has a good set of wireless interfaces, including LTE, NFC and Bluetooth 5.0. The main camera is dual – 8+5 megapixels, the front one – 5 megapixels and can unlock the screen by face. For those for whom this protection is not enough, a fingerprint scanner is provided. A 2/16 GB version is available in Russian retail; on Aliexpress you can buy a 3/32 GB version, which is more relevant given the combined slot for SIM and memory.

Advantages:

Complete protection from any external influences.
Excellent autonomy.
Not bad cameras.
There are LTE and NFC.
Fingerprint and face protection.

Flaws:

Old processor.
Combined slot.
Low resolution, however, for a small diagonal, the purpose of the device and in order to save battery, this is justified.

Ulefone Power 3

Display: 6 inches, FHD+
Processor: Helio P23
Memory: 6/64 GB
Battery capacity: 6080 mAh
Operating system: Android 8.1

Price: from 7,790 rub.

The 2021 model from Ulefone, due to its “age,” has a very pleasant price tag, but at the same time it is not at all outdated in technical terms. Moreover, the device looks nicer in terms of filling than any competitor in this rating. But first of all, it is worth noting the design - this is a classic gadget with an 18:9 aspect ratio without cutouts for the camera, but simply with a thin frame. There are 4 cameras here - two in front and two in back. The main module is 16+5 MP, the front module is 13+5 MP. The pictures are of high quality.

The hardware is more than decent - a powerful processor from MediaTek capable of running even heavy games and 6 GB of RAM. Internal storage – 64 GB. The card slot is combined, but rare users will need to install an additional microSD here. In addition, the device has various amenities - an event indicator light, an excellent battery with fast charging and a Type-C connector, and a finger scanner.

Advantages:

High level of performance – enough for gaming.
Good cameras.
Excellent battery life and fast charging.
There is an event sensor.
Fingerprint sensor.
With a large battery, the smartphone is quite thin - 9.85 mm.
Good sound quality.
Protective glass on the screen.
Excellent high resolution display.

Flaws:

At the start of sales, the device had a vulnerability - the speaker broke; in later batches, according to reviews, there are no problems.
No NFC.
There is no headphone jack, but an adapter is included.
Impressive weight – 210 grams.

Rating of smartphones with a powerful battery

Poco is a special gaming line of Xiaomi smartphones, which, in addition to high performance, boasts a good balance of price and quality. A 5160 mAh battery is installed inside the device. This is a fairly average battery for this segment of mobile phones. A mid-budget Snapdragon 720G processor is installed. The largest share of energy consumption is made up of an IPS display with a screen refresh rate of 120 Hz. PUBG uses 8-9 percent of your battery per hour. The phone can withstand about 13 hours of continuous video streaming with Wi-Fi turned on, which is pretty good for a 120Hz screen. Complete charging brings the battery up to half in half an hour, and up to 100% in 65 minutes. There is even an infrared port, forgotten by other manufacturers, which is used to control other devices at home.

MediaTek Helio G85 processor.

Average price: RUB 15,350

The rating continues with the top smartphone in the Redmi line - Note 9. The smartphone is equipped with one of the latest MediaTek Helio G85 processors. Despite MediaTek's reputation, this chip works very efficiently with the phone's resources, allowing it to last for a day and a half when paired with a 5020 mAh battery during normal use. In the case of games, about 10-12 percent of the charge per hour is consumed. When playing video, the smartphone will last 16 hours with Wi-Fi turned on. These are pretty good figures, especially considering the rather power-hungry, but beautiful and bright IPS display.

The last Samsung in the ranking was the youngest model in the series - M21. It, like the two previous smartphones, boasts a 6000 mAh battery, a mid-range Exynos 9611 processor and a proprietary Korean SuperAMOLED display with a diagonal of 6.4 inches. Unlike older versions, it has only 4 GB of RAM and 64 GB of storage, and also has a worse camera. At the same time, the phone still remains a good example of autonomy: with active use, about 20 percent of the charge will remain by the end of the day. The phone can withstand about 15 hours of continuous viewing of YouTube videos.

Peculiarities:

bright SuperAMOLED display with high energy efficiency;
good processor for a budget phone;

MediaTek Helio G35 processor.

Average price: RUB 11,650

Another representative of the budget segment of the rating, Realme C15, boasts an impressive 6000 mAh battery. This was achieved by installing a modest IPS display with a resolution of 720 pixels and a budget Helio G35 processor. Modest power consumption allows you to get crazy battery life: the phone can withstand 25 hours of YouTube, 10 hours in Asphalt 9. Overnight the phone loses only 1 percent of its charge. There is no fast charging, but the included power adapter charges the phone to 100% in 3 and a half hours. The manufacturer also had to sacrifice the camera, which here produces rather mediocre photos.

Peculiarities:

impressive autonomy;
low cost;
mediocre photographs;
poor performance in demanding games;
The screen is quite low resolution.

The final smartphone in the ranking was Redmi 9 with 4 GB of RAM. This is a fairly mainstream smartphone from a Chinese brand that has all the necessary functions of a modern phone, from a FullHD IPS display to NFC and an infrared port. A 5020 mAh battery is installed with the ability to quickly charge with adapters up to 18 W. An energy-efficient Helio G80 processor is installed.

Xiaomi Redmi 8A

Display: 6.22 inches, HD+
Processor: Snapdragon 439
Memory: 2/3 GB and 32 GB
Battery capacity: 5000 mAh
Operating system: Android 9.0

Price: from 7,600 rub.

Xiaomi has seriously decided to take share from its competitors. Each new device finds something to surprise. So the new 8A is an inexpensive smartphone with a powerful 5000 mAh battery. It is charged via modern Type-C and has a fast charging function. For the money, the device is interesting - a good, fresh processor from Qualcomm with eight cores, a sufficient supply of its own memory and the ability to install microSD in a separate slot. The model runs on the current version of Android.

There are some drawbacks - a modest resolution for such a large diagonal (this does not affect the overall image quality), a small amount of RAM in the cheap version, and single cameras on the back and front - 12 and 8 megapixels. They take pictures well, but the single module looks no longer fashionable. Instead of unlocking with your finger, there is face scanning - the camera is located in a drop-shaped cutout, which ultimately gives a larger usable screen area. The device is available in several colors – black, blue and red.

Advantages:

Excellent battery capacity and autonomy.
Fast charging.
Fresh chipset.
Fresh OS.
There is face unlocking.
Separate slot for memory card.

Flaws:

Single cameras do not look modern, but this does not affect the quality of shooting.
The resolution could be higher.
No NFC – considering that this is a Xiaomi smartphone, it’s not surprising.

DEXP Ixion XL145 Snatch

DEXP are known to be the only ones who have a series of smartphones with high-capacity batteries. This line includes 11 models, which are equipped with 3000-5200 mAh batteries. In this article, we are only interested in those that have a capacity of 4000 mAh and above.

The characteristics of the phones in this series are very different. In any case, this is rare, since other manufacturers offer a maximum of 2 models with a powerful battery.

DEXP Ixion XL145 Snatch
DEXP Ixion XL145 Snatch is a fairly compact smartphone.
Under the cover is a 4000 mAh battery. It has a 4.5 inch display (IPS+OGS). The screen resolution is 540 by 960 pixels. The heart of the device is the eight-core MediaTek MT6592, clocked at 1.7 GHz.

Processor: Snapdragon 439
Memory: 3/32 GB
Battery capacity: 5000 mAh
Operating system: Android 9.0

Price: from 8,990 rub.

The new product from Vivo is a good smartphone in terms of features and price. It can be called a direct competitor to the previous gadget – Redmi 8A. They are very similar - a large screen with a teardrop notch, the Y11 has a larger one, but the resolution is still HD+. Both devices run on the same chipsets and have the same memory set; the Y11 also offers a separate expansion slot.

The difference is that the gadget from Vivo was marked by a dual main camera – 13+2 MP and a single front camera – 8 MP. Their work is complemented by AI, which promises pleasant pictures as a result. Reviews confirm this. In terms of cameras, many will prefer this device. However, there is also an argument against the purchase - the old microUSB connector and the lack of fast charging - a full set of capacity will take about 3.5 hours. A fingerprint sensor is provided for protection.

Advantages:

Excellent autonomy due to a capacious battery and energy-efficient algorithms for its operation.
High quality camera.
Nice appearance.
Modern OS version.
Fingerprint sensor.
Decent performance.
Separate slot for memory card.

Flaws:

In bright light the screen lacks brightness.
The low resolution is felt in games and when watching movies in high quality.
Old microUSB connector.
It takes a long time to charge.
No NFC.

Flagship models

When creating flagship models, the most advanced technologies are used, due to which the device can last much longer on a single battery charge. In this group of mobile devices we note the following models:

Samsung Galaxy S7 Active is a market leader in mobile devices and has a 4000 mAh battery. The Korean manufacturer increases the service life of its devices by optimizing software and hardware. The body of the model is a combination of plastic and rubber; mechanical keys are placed on the front.
The Asus Zenfone 3 Zoom is another expensive offering. It is characterized by the presence of two rear cameras with an optical zoom function. The installed display is made using AMOLED technology, the memory is 64 GB, and the battery capacity is 5000 mAh. High-quality metal is used in the manufacture of the case.
