Best Battery Life Phone 2024
Until recently, even the most innovative smartphones suffered with low battery life. The contrast with older gadgets was especially annoying; early smartphones consumed little energy and could last a couple of days without recharging. Now that the trend has changed, we expect a device marketed as a phone with longest battery life to work 15-20 hours without recharging. In this review, we have collected a variety of phones with the best battery life, from flagships to budget models.
Which Smartphone is Best for Battery Life Right Now?
In our tests, the Asus ROG Phone 9 Pro became the smartphone with best battery life. Its battery life was more than 20 hours with active use, including playing video at maximum screen brightness. We were also pleased with the results of the iPhone 16 Pro Max. It worked for more than 17 hours straight. Of course, the manufacturer declared more, but at the moment it is the best result among iPhones. Also, depending on the testing method, results may vary.

Asus ROG Phone 9 Pro – Best Phone for Battery Life Overall
In our tests, the Asus ROG Phone 9 Pro became the best battery life phone, working for 20 hours and 34 minutes without recharging. Since the smartphone has an adaptive refresh rate, for the purity of the experiment we used it again at the maximum refresh rate of 165Hz, and it worked for more than 15 hours, which is also impressive. Asus 9 Pro is equipped with a 5800mAh battery and a 65W fast charging function, thanks to which the smartphone can be charged from 0 to 100% in just 50 minutes. Also, this model is not deprived of a good processor. Asus ROG Phone 9 Pro has a Snapdragon 8 installed, so we were pleased with the performance. Such good results are not surprising, since It is an Asus’s flagship smartphone with a price tag of $1,199. Overall, Asus 9 Pro is marketed as the best battery life phone for gaming, and it lives up to this name.
| Pros | Cons |
| Superior battery life | Little software support options |
| Snapdragon 8 processor | Dull pictures on main camera |
| Display with 165Hz refresh rate |
Asus ROG Phone 8 Pro
Asus ROG Phone 8 Pro can easily be called a phone with best battery life for active people. It has excellent performance thanks to the Snapdragon 8 Gen 3 processor installed on it and up to 24GB of RAM. Despite this power, the smartphone consumes energy moderately. With a 5500mAh battery, it was able to last almost 19 hours in our test. The Asus is also equipped with a 65W fast charging function, with which it charges 100% in just 40 minutes. The only thing is that the camera was a little disappointing. A $1,099 smartphone should have significantly better photo quality.
| Pros | Cons |
| Water resistance | Modest camera |
| Various gaming features | |
| Long battery life | |
| Impressive performance |
OnePlus 12R
The OnePlus 12R is one of the best battery phones with 5500 mAh battery, which provides up to 18 hours and 08 minutes of active use. It’s especially convenient that the device supports 100W fast charging, which allows you to fully charge your phone in just 26 minutes. Under the hood lies a powerful Snapdragon 8 Gen 2 processor, which is responsible for high performance and energy efficiency. We are also pleased with the good image quality on OnePlus. But you’ll hardly be able to enjoy taking photos on it, since the smartphone’s cameras are of mediocre quality, although there are 4 modules, and it seems like the manufacturer places an emphasis on it in the design. The price of OnePlus 12P is quite affordable and starts at $480.
| Pros | Cons |
| Powerful processor | Weak cameras |
| Fast charging function | |
| Nice display |
Apple iPhone 16 Pro Max – Best Apple Phone for Battery Life Overall
The Apple iPhone 16 Pro Max comes with a 4685mAh battery, providing a remarkable 17 hours and 17 minutes of active use. This model supports fast 30W charging and can reach 100% in one hour. Thanks to the innovative A18 chipset, which incorporates advanced AI features, one might expect increased battery consumption. However, the ample battery capacity effectively compensates for this. While there are some concerns about Apple’s choices related to updates and design in the iPhone 16 line, this model stands out in terms of energy efficiency, being a phone with best battery life among iPhones. As the latest and most advanced model, it is unsurprisingly expensive, starting at $1,299.
| Pros | Cons |
| One of the longest battery lives | May be too expansive |

Like many smartphones with high technical specifications, the OnePlus 12 has mediocre shooting quality. And at the moment the smartphone does not support any AI functions. It’s not crucial, but, for example, Samsung models in the same price category from $600 support work with AI.
| Pros | Cons |
| Reasonable price | Doesn’t support AI |
| Bright screen | Takes dull pictures in low lighting |
| Good quality camera | |
| Wireless charging |
Asus Zenfone 11 Ultra

Under the hood, the Zenfone 11 has a Snapdragon 8 Gen 2 processor, which provides the smartphone with quite satisfactory performance. I was also pleased with the quality of the shooting. This Asus smartphone has a camera set consisting of a 50MP main camera, a 13MP wide-angle lens and a 5MP macro camera. Good camera quality is a rarity for smartphones that focus on performance and battery life. The only disappointment was that the manufacturer only provides 2 years of support for Android updates, which is too little, especially for a $999 smartphone.
| Pros | Cons |
| Long battery life | Limited software updates |
| Reasonable price | |
| Good camera |
Samsung Galaxy S24 Ultra – Best Android phone for Battery Life
In our experiment, Samsung Galaxy S24 Ultra took 7th place, having worked for 16 hours and 45 minutes. So it’s definitely not the one Android phone with best battery life, although it’s still good. Galaxy S24 Ultra has a 5000mAh battery and works in adaptive mode, which changes screen refresh rate from 1 Hz to 120 Hz. Support for fast charging 45 W allows you to fully charge the battery in 1 hour 27 minutes. It’s worth saying that if you need a Samsung with a capacious battery, you don’t necessarily have to pay $1199 for this flagship model, since many smartphones from the A and M lines also have an impressive battery capacity.
| Pros | Cons |
| Rich display | Quite expansive |
| Incredible performance | Questionable color accuracy |
| The most innovative Android OS | |
| AI support | |
| Has an S Pen |

We can’t say that this smartphone belongs to the budget segment, so we wouldn’t ask for a completely poor package for it.

How We Test for the Best Phone Battery Life
To determine what phone has the best battery life, we started by continuously using each smartphone on basic settings, including activities such as playing videos and surfing online, to closely simulate everyday usage. Throughout this phase, our goal was to observe how long the battery lasted under typical conditions. To delve deeper, we conducted additional tests on phones with adaptive refresh rates set to the maximum. This setting often increases the display’s power consumption, providing insights into how these devices manage higher performance demands.
