The Oppo A5 Pro 5G may not shine in all areas, but its excellent battery life is hard to overlook. With a price tag of around $279, it serves as a robust choice for those needing a device primarily for calls and emails.
In our tests, the 5800mAh battery easily lasted an entire day of streaming, messaging, and listening to music without dipping too low. Users who engage in less intensive tasks could potentially stretch usage over two days without charging.
The 120Hz screen refresh enhances the scrolling experience, making it perfect for social media. Plus, the IP69 rating means added durability against dust and water.
However, the device slows down noticeably during regular use, primarily due to the MediaTek Dimensity 6300 chipset. The low display resolution of 1604 x 720 does further dampen the experience, yet the Oppo A5 Pro remains a commendable option for budget-conscious professionals.

8. HMD Skyline – Best Repairability
Pros
- Sharp 6.55-inch screen

- Lacks headphone jack
Price When Reviewed:
$499.99
- Battery test score: 18:23

The Xiaomi 15T Pro is not only noted for its battery prowess, but it stands as a superb value that positions it well against pricier rivals, retailing at around £649.
In our PCMark testing, it demonstrated impressive endurance, lasting 16 hours and 39 minutes—surpassing both the Pixel 10 and Honor 400 Pro. During actual use, we achieved over two days of battery life without needing to recharge, making it a perfect choice for those who find their phones struggling to keep pace.
With 90W wired charging and 50W wireless charging, you won’t be kept waiting long when it comes time to recharge. The generous battery capacity holds strong even while powering a vibrant 6.83-inch 144Hz OLED display, supporting streaming of movies and gaming sessions without stress.
While HyperOS can feel cumbersome compared to stock Android or OxygenOS, this is a minor setback when put next to the top-tier cameras capable of some of the best imagery we’ve seen from mid-range devices.

Other Phones Evaluated
While the current assortment in this article is our favorite when it comes to battery efficiency, other devices were evaluated closely.
For instance, the HMD Fusion, with unique customisation options and repairability, faces stiff competition from the Fairphone (Gen 6). Its battery is easily replaceable to avoid degradation and boasts a remarkable eight years of software updates — a solid investment for less frequent upgrades.
Currently, only the iPhone 16 Pro Max pervades the list, but the iPhone 16 Plus also impresses with the potential for up to two days of battery life under certain conditions. The new iPhone 17 series may further lengthen battery longevity when we get to benchmark it.
Despite the inclusion of two Nothing devices already, the Nothing Phone (3) failed to secure a spot; however, it remains a strong contender. If you prefer the aesthetic of the Nothing Phone (3a) and want enhanced specifications for a refined experience, this could be an ideal choice for you.
Interestingly, the stunning Motorola Edge 60 Pro did not perform as well in our PCMark battery assessments but excelled in day-to-day use. Its attractive design distinguishes it in a market full of more mundane-looking phones.

Our Mobile Editor, Anyron Copeman, meticulously maintains this guide to top battery life phones. His editorial efforts focus nearly exclusively on mobile technology, with assistance from Reviews Editor Chris Martin, who brings nearly 15 years of phone testing experience.
Selecting the Optimal Phone for Battery Life
When seeking a phone with outstanding battery longevity, it’s critical to evaluate each device through various tests.
This includes tracking typical battery drainage during everyday tasks and measuring power retention after 30 minutes of charging. These observations are measured against hard data from PCMark’s battery assessment, which simulates real-time demands to gauge performance.
This comprehensive approach empowers buyers to see through marketing claims, ensuring devices align with personal usage patterns.
Moreover, every phone listed is evaluated for proficiency in other essential qualities, such as camera performance, display quality, and overall capabilities. There’s no advantage in great battery life if a device is lacking in other substantial areas.
Buyer’s Guide for Battery Life Phones
1.
Understanding Battery Capacity Measurements
Battery capacity is quantified in milliamp-hours (mAh); generally, higher mAh ratings indicate greater capacity. That said, more substantial batteries do not automatically equate to superior battery life.
Efficiency lies in a device’s processor and software, as well as personal usage trends. Premium devices may need larger batteries to support their advanced features while maintaining longevity.
2.
Factors to Keep in Mind When Buying
Consider the intended uses for the phone before purchasing.
Larger screens with high resolutions will inherently reduce longevity compared to devices with smaller displays. Some models may claim large capacity batteries for endurance but lack impressive charging speed, making recharging tedious if not done overnight.
Effective fast-charging rates to note moving into 2025 should surpass 45W, with some models even exceeding 80W and beyond, which speaks to the top tier in the market.

Review Summaries of Our Findings
We ensure consistency by including only devices tested with our advanced benchmarks, such as PC Mark for Android’s Work 3.0 battery evaluations. iPhones are an exception, as we assess them based on practical use and experience.
It’s important to clarify that results yield readings as durations, but these do not definitively indicate real-world usage.
Each test is conducted under uniform conditions, with consistent screen brightness (set to 200 nits) to guarantee a fair trial. The device is allowed to naturally drain while continuous processes run.
For instance, if a device lasts 12:15 during a test, it implies it remains active for 12 hours and 15 minutes under set conditions. These results may differ from a phone’s reported screen-on time because personal usage and power management settings dramatically impact real-life experiences.
