The best smartphones with a powerful battery in 2023

In recent years, the autonomy of smartphones has improved markedly. Thus, chipset manufacturers have switched to advanced technical processes, and standard software developers are trying to optimize it. OLED matrices have become common, which in a number of usage scenarios consume less energy – and the screen, as you know, is the main consumer of battery power. And the latter (finally!) have become much larger – now 5000 mAh is not such a rarity.

But the more autonomy increases, the greater the “appetites” of users become, for whom the smartphone has become the center of entertainment, work, navigation and much more. So, there is no such thing as too much battery. And to be called the best smartphone in the world with a powerful battery, capacity alone will not be enough. I wish there was fast and wireless charging!

realme 8

This smartphone can last as long as six days, provided that it is used only as a phone and not for games, Internet and video. If we talk about the usual scenario, when you played a little, took some photos, watched a video, surfed the Internet, then it will definitely be enough for two days. Included is a charger that produces 30 watts. This is enough to charge a powerful battery from 0 to 60% in less than half an hour. And it takes another 40 minutes to get the battery to 100%.

 

Top 15 best smartphones with a powerful battery in 2023 according to KP

Xiaomi Poco M3

A phone with high-performance hardware that offers long battery life. Not only does the power source have greater capacity than most smartphones sold today, but the battery life expectancy is superior to most modern portable batteries. The most important part of the smartphone is the screen, which can display images with a high level of detail corresponding to the FHD+ standard. Not every smartphone in this price category is equipped with a display that supports this image standard. The plastic casing on the back panel imitates the texture of leather, which provides a more comfortable grip on the phone.

TECNO Pova 2

For 2023, this is a mass smartphone with the largest battery capacity. 7000 milliamps/hour is an outstanding figure. But the owner must “pay” for it with the dimensions of the gadget. We warn you, you should not buy it without first holding it in your hand – especially for ladies. 

This battery reserve is enough for continuous operation of the display for one and a half days – in the so-called reading mode. That is, under normal usage scenarios, the average modern user will more than have enough charge for two days, and not for a demanding user for three to five days. It’s a pity that the phone doesn’t support fast charging. It takes about three hours to wait for the battery to fill from 0 to 100%.

The phone runs on a G85 processor. It can conditionally be called a budget device for games. Modern 3D shooters cannot handle higher than average graphics settings, but with these settings virtual battles take place comfortably. This means there are no complaints in everyday tasks. Externally, the “tube” looks modern. Thin display frames, no cutout for the front camera – the lens is directly on the display. The rear camera works well even at night scenes.

ASUS ROG Phone 5s

This line of smartphones is for gamers. And a powerful battery for such a device is a must-have attribute in 2023. The battery charging algorithm is not the same as many other models: the smartphone itself calculates the optimal time and current for charging, depending on the situation. For example, when you charge a gadget overnight, it will take longer to charge, since there is nowhere to rush, and keeping the battery under voltage for a long time is harmful. During the day, on the contrary, it will be fully charged in less than an hour.

We won’t talk much about the filling – the person who buys such a device in most cases already knows all its nuances. Let’s summarize: everything inside is top-notch. Of course, there are more powerful models on the market. But to play modern shooting games and racing games with the best graphics settings, that’s enough. 

It will also appeal to those who like to edit videos and process photos. The phone also has a version without the S prefix – it came out about a year earlier, is externally identical, but the processor is slightly weaker.

Ulefone Power Armor 13

The brand produces “armored” smartphones. Of course, they won’t stop a bullet. But it’s easy to survive falling on asphalt, diving into sand and under water! The brand is valued among extreme sports enthusiasts, hunters, and fishermen. It is jokingly called the “doomsday smartphone.” The battery here is the most powerful – 13,200 milliamps/hour. This is enough to surf the Internet for 40 hours non-stop. Or about a week of normal use. 

There is fast charging, but with such a large battery it is not enough. Judge for yourself: in half an hour, about a quarter of the capacity is charged, but for maximum 100% you need another 2.5 hours. And if you charge with a non-original wire, then the full cycle takes about five hours.

The smartphone has a decent processor, a lot of RAM and built-in memory. This is top in its class. However, the tube weighs almost half a kilo and will not fit into every pocket. The manufacturer even suggests attaching it to a carabiner for unloading or a belt. 

Main characteristics

Oukitel K15 Pro

Another “armored car” in our ranking of the best. However, the manufacturer is trying to bring its appearance closer to a classic smartphone. The battery here has a capacity of ten thousand Machs. Please note that there are two versions on sale: Pro and Plus – the second is cheaper and has worse characteristics, but the appearance and battery capacity are identical. Charging the battery to 100% takes about three hours. In standby mode, it can hold a charge for about 30 days.

The Mediatek Helio P60 processor in the K15 Pro is considered obsolete in 2023. Modern games run poorly, and it takes time to launch the camera and demanding applications. Inside the smartphone there is a set of utilities typical for such mobile phones: a magnetic compass, orientation, proximity, light and gravity sensors.

Xiaomi Redmi 9T

The Redmi line is the maximum balance of price and quality. It began with the brand making a minimal markup on the cost of parts. This is how gadgets gained their popularity. The ninth Redmik has many variations with different postfixes C, A or no letter at all next to the model number. The T version has a powerful battery. The original charger fills 100% of the battery in two and a half hours.

The Snapdragon 662 processor is mid-range. It is still relevant in 2023, but users have reported a number of performance issues when processing large amounts of data. For example, a heavy website loads with noticeable lags. 3D games run at low quality settings. An advanced user and technology fan will notice the nuances and will be dissatisfied. 

But if you need a phone to make calls and communicate via instant messengers, then no problem. The rear camera is acceptable, the photos are slightly blurry. You shouldn’t expect stunning selfies from the front camera.

Infinix Hot 11 Play

This manufacturer is just entering the Russian market and has not yet gained much fame. But the brand has already earned respect from technology fans who want to save money. A capacious battery, combined with a well-optimized shell and a not-so-fast processor, have a positive effect on operating time. Two to three days under normal usage scenarios is a pretty good indicator. It’s a pity that the included charger only provides 10 W, which is why it takes almost five hours to fully charge.

The phone has a proprietary Power Marathon function. When there is very little charge left, increased energy saving is activated so that resources remain, for example, making a call or sending a message. The technical hardware copes well with everyday use cases and handles simple games. The camera is soapy and not very sharp – a common solution for a budget model. During the day the photo quality is acceptable.

Lenovo Legion Pro

A gadget with a daring youth design. The mobile phone has two Type-C ports, which are used for charging or connecting joysticks and other gaming devices. The first is traditionally from below, the second is from the side. Two ports are also needed so that the user can charge it and still hold it comfortably in his hand. And if you plug the charging cable into both sockets, charging will go twice as fast – in just half an hour the smartphone will be charged to maximum. Accordingly, charging through one cable takes about an hour.

Technical characteristics are excellent. In 2023, all games and applications will fly. The blissful picture is complemented by a juicy AMOLED screen with support for 120 and 144 Hz – with such a display, all animations look very smooth. The phone has powerful speakers. What’s unusual is the location of the camera. Block with lenses in the center of the body. This was done specifically so that the player – after all, it was made primarily for gamers – could comfortably hold the mobile phone horizontally. Photos come out very sharp. You can record videos in 4K resolution.

BQ 6630L Magic L

In the line of the domestic brand for 2023, this is the phone with the most powerful battery. The company operates in the low price segment, so expecting miracles of performance, a sharp camera, and a large amount of RAM from it is reckless. At the same time, for its price it is a good device. Moreover, taking into account the battery capacity of 4920 mAh, it is enough for two days of moderately intensive use. But the budget played a cruel joke – it takes at least four hours to charge the gadget. Fast charging is not supported here.

Its performance is enough for simple games, instant messengers and the Internet. The screen is large, the gadget fits well in the hand and, despite the glossy body, does not slip. The sensor, in budget fashion, is placed on the back cover, rather than built into the screen or unlock button. However, some people find it more convenient. The model as a whole has good ergonomics. The camera is only suitable for pictures with good lighting.

Samsung Galaxy M52

There’s an interesting story behind this gadget. Its predecessor, number M51, had a battery of 7,000 Machs – the model is now out of production and a new one cannot be found on sale. The community of tech bloggers thought: since they set their sights on such a record capacity, they will continue to delight the audience. No such luck – you get 5000 mAh. Of course, this is a smartphone with a powerful battery, but after the last hit it is disappointing.

The smartphone supports a screen refresh rate of 120 Hz. That is, all the animations when scrolling through social networks, in games and on the Internet are very beautiful. Charging is enough for an honest working day and evening. But if you disable this function and set the screen to the usual 60 Hz frequency, the mobile phone will last two days. The battery charges in approximately two hours. You can praise the gadget for its good build, sharp and fast camera. Performance for everyday tasks, games and video processing is decent.

Nokia C30

A smartphone with the largest battery in the Finnish brand’s lineup. Fully charges in about three hours. And with normal use, the battery lasts for three days. In many ways, the secret to such performance is a weak processor. The model is called a “dialer”, hinting that except for communication and surfing the Internet, this gadget is difficult to use for other tasks – it simply won’t last.

But we get a price that is quite affordable for 2023. It also runs on pure Android. It is believed that this is an ideal solution for low-performance gadgets. Plus, no junk software on the internal memory upon purchase. There is a fingerprint sensor and face unlock. The quality of the cameras can be described with the phrase: “There is a camera and that’s okay.”

Samsung Galaxy M31

The screen brightness is enough for comfortable use outdoors in direct sunlight. The camera module is capable of fast and clear pictures with a high level of detail even in low light. The amount of RAM allows you to keep resource-intensive applications open in parallel without any loss in the usability of the phone; this speeds up the discharge process, but is compensated by the capacity of the batteries. The presence of NFC technology, a memory card slot, and a mini jack acoustic connector have turned this smartphone into a universal and useful assistant, with potential that will last for several more years.

How to choose a smartphone with a powerful battery

We recommend choosing a smartphone with a powerful battery based on the following criteria:

Battery

The battery determines how long the smartphone will work without recharging. A battery with a capacity of 5000 mAh or more can be called powerful. Smartphones with such a capacity can last from 3 to 5 days on a single charge with minimal use (rarely answering calls and SMS). The maximum nominal battery capacity of gadgets can currently exceed 10,000 mAh, but the actual operating time depends on the optimization of the software and hardware of the developers. 

operating system

You can choose a smartphone with Android and iOS operating systems. There are also realme UI and MIUI shells based on Android.

Most smartphones in 2023 come with Android OS¹ . Among the advantages of this software are the availability of flexible interface settings, additional options for advanced users, as well as a significant number of free applications on Google Play.

The main advantage of iOS is that it is tailored strictly for Apple devices, which means that such a system is a priori stable. It is also necessary to note the reliability, high performance and well-established communication when working with the software. In addition, iOS has a high level of security, stable updates and a clear interface.

The realme UI and MIUI shells are based on Android. They have no significant differences from “pure” Android, but additional software has much wider functionality: individual customization of the desktop, a second space (two separate desktops) and Mi-Drop for fast file transfer (analogous to AirDrop from iOS).

Screen

Pay attention to the screen diagonal and its resolution. The higher these indicators, the more comfortable it is to watch movies and play games. But gadgets with large screens also have their drawbacks, the main one being their large size, which is why they may not fit in your pocket. 

The optimal screen size for a modern smartphone starts from 6 inches and above. Resolution affects the clarity of the image. The most common: HD (720p), Full HD (1080p), Quad HD (1440p) and Ultra HD (2160p). Most often, users choose smartphones with Full HD² resolution . 

In the case of Quad HD and Ultra HD, images are clear and realistic, but extra pixels consume more power, which affects the battery life of devices. In HD, the picture will be less clear in games and videos.

Matrix

The brightness and clarity of the image is affected by the type of matrix. It comes in the following types: 

• IPS is bright and not very expensive to produce. This matrix has a large reserve of brightness and natural color reproduction, but due to the separate backlight layer in the design, the power consumption is quite high.

• OLED (modifications AMOLED, Super AMOLED, Dynamic AMOLED) is more expensive to produce, but conveys deep and rich color. At the same time, OLED has higher contrast, very low power consumption and small thickness, which allows you to make the device thinner.

In modern devices you can find AMOLED and Super AMOLED modifications. They have no differences in image forming technology, but there are differences in the way the touch matrix is ​​attached: the touchscreen is integrated directly into the display, and is not superimposed on top, as in a regular AMOLED. Due to this, the air layer is removed, the amount of reflected external light is reduced, and the image becomes even brighter.

Cameras

The camera resolution of some flagships reaches 108 megapixels. And the main sensor comes to the aid of several additional sensors designed to improve the quality of pictures. For example, an ultra-wide-angle lens captures more space and is ideal for shooting landscapes, a portrait lens blurs the background, a telephoto lens is suitable for shooting distant objects, and a macro camera allows you to capture small objects at close range. 

Also, one of the main characteristics affecting the quality of photo and video shooting is the matrix. The matrix size is calculated in fractions of an inch, and is indicated in the parameters as 1/x. The larger it is, the more light it captures. This means the higher quality and more detailed photos and videos are obtained. Another important criterion is optical stabilization (a system to counteract camera shake). The technology compensates for camera movement and prevents image blur.

But do not forget that a good camera combines powerful hardware and competent software, which are properly configured and work harmoniously with each other. This is why smartphones with the same camera characteristics can shoot completely differently.

 

Additional functions
