Best Battery Life Phones 2025 – Power That Lasts

Best Battery Life Phones 2025 – Power That Lasts

Battery life remains one of the top priorities for smartphone users in 2025. Manufacturers are equipping devices with larger batteries and more efficient chips, resulting in phones that can easily last a full day (or more) on a single charge. Below, we break down the flagship, gaming, budget, and even refurbished phones that offer exceptional battery performance, with up-to-date specs and real-world test results to back them up.

Flagship Phones with Exceptional Battery Life

The latest flagship phones combine high-capacity batteries with efficient processors for all-day endurance.

  • Apple iPhone 16 Pro Max (3582 mAh) 

Apple’s 2024 flagship delivers the best battery life ever seen in an iPhone. In tests, it lasted around 22 hours of continuous web browsing, 10+ hours of video streaming, and 12 hours of gaming on a charge. 


This endurance comes from its slightly larger battery and the ultra-efficient A18 Pro chip, allowing the 16 Pro Max to outlast even its predecessors. Its MagSafe wireless charging adds convenience for those looking for a battery that lasts all day on phones.

  • Apple iPhone 15 Pro Max (4441 mAh) 

The iPhone 15 Pro Max sets a new standard for battery life in Apple's lineup. Boasting a larger battery capacity than its predecessor, with the introduction of the A17 Bionic chip, the iPhone 15 Pro Max achieves unparalleled efficiency, enhancing its battery life. 


The iPhone 15 Pro Max also supports the latest MagSafe wireless charging, offering a convenient and fast way to recharge your device.

  • Samsung S24 Ultra (5000 mAh)

The Samsung Galaxy S24 Ultra takes everything you love about the S23 Ultra and pushes it even further. Featuring a robust 5000 mAh battery, it is engineered to support even more hours of video playback and all-day usage, ensuring that your phone keeps up with your busy schedule.


Alongside its superior battery life, the S24 Ultra boasts an advanced camera system, likely improving upon the 200 MP main camera in the S23 Ultra, setting new benchmarks for mobile photography.

  • Google Pixel 9 Pro (5100 mAh)

The Google Pixel 9 Pro is built for efficiency, featuring a 5100mAh battery that delivers exceptional longevity, even under heavy workloads. Powered by the Google Tensor G4 chipset, it optimizes battery consumption based on usage patterns, significantly extending screen-on time. 30W wired and 23W wireless charging ensures you’re powered up quickly, making it an Android phone with the most extended battery life for professionals and content creators.


Gaming Phones with Marathon Battery Life

Gaming-oriented phones often include massive batteries and aggressive cooling to sustain long play sessions without frequent charging.

  • Asus Zenfone 8 Flip 5G (5000 mAh)

Asus Zenfone 8 Flip flagship delivers impressive endurance with its 5000mAh battery. While slightly smaller than gaming phones, it’s designed for power users, content creators, and mobile enthusiasts who need a device that lasts all day. The Snapdragon 888 5G chipset ensures fast performance, while WiFi 6E offers stable connectivity. The Flip Camera technology provides high-quality front and rear shots, making it a top choice for photography lovers.

  • Asus ROG Phone 7 Ultimate (6000 mAh)

With its monstrous 6,000mAh battery, the ROG Phone 7 Ultimate by Asus is the best battery life phone in terms of battery capacity. It can power through hours of intensive gaming and multitasking. This Asus gaming phone also boasts a 65W fast charging feature that can fully charge the battery in just 42 minutes, allowing you to get back to gaming in no time. With these specs, this device makes it to the top of our best gaming phone guide. 


Other Notables: Recent gaming-centric models like Xiaomi’s Black Shark 6 and ROG Phone 7 Ultimate (both ~6000 mAh) similarly deliver multi-day battery life with heavy use. The key is their combination of high capacity and aggressive performance tuning. If gaming endurance is your priority, a dedicated gaming phone will outlast typical flagships in the same performance class.

Budget Phones with Long-Lasting Battery

Mid-range and budget phones often include efficient chips and lower-res screens, meaning their 5,000+ mAh batteries can last even longer in practice.

  • Motorola Moto G (5000 mAh) 

This affordable Motorola phone is a battery champ. It delivered about 12 hours and 43 minutes of active screen use in tests, including 12+ hours of web browsing and 16 hours of video playback on a charge. Many users report getting 2 full days of moderate use thanks to its power-sipping Snapdragon 6 Gen 1 chip. The Moto G Stylus 5G’s endurance even beats some flagships, making it ideal for those who need great battery life on a budget.

  •  OnePlus 11R 5G (5000 mAh)

The OnePlus 11R 5G powerful mid-range phone boasts a 5000mAh battery and impressive endurance. It provided over 12 hours of active screen time in tests, including web browsing and video playback. The Snapdragon 8+ Gen 1 chip ensures power efficiency, extending usage to nearly two full days on moderate use. While not a flagship, its battery outlasts many premium models. (It also supports 100W SuperVOOC fast charging, making quick top-ups effortless, making it one of the most efficient smartphones for users who need all-day power.


Others: Devices like the Motorola Moto G Power and Redmi Note series also consistently offer 5,000–6,000 mAh batteries, prioritizing longevity. For example, the Moto G Power (2023) and Redmi Note 12 comfortably give 2+ days of light use on a charge, making them favourites for battery-focused shoppers.

Refurbished Phones That Still Hold Up in 2025

Buying a recent flagship second-hand can yield top-tier battery life at a lower cost. These older models remain highly competitive in endurance.

  • Apple iPhone 13 Pro Max (4352 mAh)

A modern classic, the iPhone 13 Pro Max is still a battery life king. It was rated for 25 hours of video streaming by Apple and achieved about 10+ hours of web browsing and 19 hours of video in independent tests. It outlasted its iPhone 12 Pro Max predecessor by a huge margin and even slightly beat the 14 Pro Max in some stress tests. In a YouTube streaming endurance test, the 13 Pro Max clocked 20 hours 5 minutes, virtually tying the newer Galaxy S23 Ultra. This means a used 13 Pro Max can still easily provide all-day heavy use in 2025. 

  • Apple iPhone 14 Pro Max (4323 mAh) 

The iPhone 14 Pro Max has become Apple's best battery life phone. With a battery capacity of 4323 mAh and the A16 Bionic chip's power management features, it can endure the busiest days. The adaptive refresh rate also helps in elongating the battery life. An always-on display is a battery-draining feature, but that's not the case with this phone. The phone also supports MagSafe wireless charging. Head to our Apple Refurbished collection and get the best iPhone 14 Pro Max price only at Phonebot.

  • Samsung Galaxy S23 Ultra (5000 mAh)

Last year’s Samsung flagship was readily available and refurbished, and its battery life is outstanding. The S23 Ultra’s Snapdragon 8 Gen 2 chip brought a significant efficiency jump – reviewers saw 13+ hours of web surfing in one go and around 11.5 hours of mixed heavy use (screen, video, apps), which edged out Apple’s best-in-one test. In a controlled video rundown, it lasted 20 hours and 7 minutes, slightly beating the iPhone 13 Pro Max’s 20h 5m.

  • Google Pixel 7 Pro (5000 mAh)

While not quite on the level of the iPhone 13 PM or S23 Ultra, the Pixel 7 Pro delivered solid battery life that holds up. It can get around 6–7 hours of screen-on time in real use, thanks to Google’s optimizations. It lasted over 13 hours in video playback tests and comfortably a full day of use per charge in reviews. As a refurb, it’s cheaper to get Google’s AI features and still expect an all-day battery. (The newer Pixel 9 Pro improved efficiency further, but the 7 Pro remains a decent battery performer if you find one at a bargain.)

Find the Best Battery Life Phone for Your Needs

Whether you go for the latest ultra-premium flagship or a reliable older model, you can find phones in every category that excel in battery endurance. The flagships combine big batteries and efficient chips to push past a day of use, gaming phones maximize mAh for marathon sessions, budget phones squeeze out multi-day life with frugal hardware, and even refurbished recent flagships can rival or beat many 2025 releases in screen-on-time. Always check reputable reviews and battery test results.
