Compare the Galaxy A57 with other long-battery-life Android phones by using the same kind of battery test, then weigh charging speed, screen and workload, software support, storage, price and local availability. Samsung’s “up to two days” claim is based on a defined average-use estimate—not a guarantee or a directly comparable independent test result.
How long does the Galaxy A57 battery last?
Samsung lists a 5,000 mAh typical battery for the Galaxy A57, with a 4,905 mAh rated/minimum capacity. It advertises up to two days per charge, based on an average-use estimate from UX Connect Research. In the UK, the firm assessed pre-release SM-A576 units from January 8 to January 18, 2026, using LTE and 5G Sub6 under its compiled average-use profile. Samsung says 5G mmWave was not tested and cautions that actual results vary with use. Samsung’s A57 specifications and battery-test details therefore describe a bounded estimate, not a promise that every owner will get two days.

Capacity and runtime answer different questions. The mAh figure describes stored charge; runtime also depends on the phone’s display, processor workload, network conditions and usage. Samsung’s 2026 interim report, for example, lists a 6,000 mAh battery for the entry-level Galaxy A07 5G. That larger number alone does not establish that it lasts longer than the A57 in a comparable test. Samsung Electronics’ 2026 Q1 interim report

Which battery-life test is fair?
Start with results produced by the same publication or test setup, and check what was measured. A controlled web-browsing test, a video loop, a mixed-use estimate and a percentage-drain observation are not interchangeable. Look for screen brightness, refresh settings, network connection, task and test duration; if those details differ or are missing, treat the figures as directional rather than a definitive ranking.

Tom’s Guide reported that the A57 lost 15% in its stated test window, versus 14% for the Galaxy A56 and 16% for the Nothing Phone 4a Pro. The cited excerpt does not fully describe that test protocol, so these figures are useful as a limited same-outlet comparison, not as a prediction of daily runtime. In separate lab-hour results, Tom’s Guide reported just over 15 hours for the Pixel 10a and around 12.5 hours for the iPhone 17e. Those hour-based results should not be ranked against the percentage-drain observations as if they came from one test. Tom’s Guide’s Galaxy A57 review and battery observations
Manufacturer estimates also should not be compared directly with reviewer lab hours. Samsung’s “up to two days” reflects its stated average-use profile, while a lab test measures a particular workload and stopping point. For your own likely runtime, consider whether your routine resembles the test, especially in mobile-data use, screen time and demanding tasks.

How should you compare charging?
Samsung says the A57’s Super Fast Charging 2.0 can reach 60% in 30 minutes. This is a manufacturer charging claim about topping up; it does not tell you how long a full charge will last. Check the product listing for your country to confirm charger requirements and what is included before assuming that the stated speed is available out of the box. Samsung’s US A-series comparison says wireless charging and PowerShare are unsupported for the listed 2026 A-series models.

What else affects the comparison?
Display and workload
Samsung US lists the A57 with a 6.7-inch FHD+ display and a 120 Hz refresh rate. A phone used for frequent gaming, camera work or mobile-data sessions faces different demands from one used mostly for messaging and occasional browsing. When comparing endurance, use similar brightness, refresh-rate and network settings where possible; otherwise, a difference may reflect the workload rather than a more efficient battery system.

Software support and ownership period
Samsung promises up to six generations of OS/One UI upgrades and up to six years of security updates, subject to model, market and rollout timing. That matters when deciding how long to keep a phone, but it does not indicate how many hours it will run on one charge. Samsung’s launch announcement and update-support commitment
Storage, expansion and local fit
Samsung’s US comparison lists the A57 with 8 GB RAM and either 128 GB or 256 GB storage, without microSD expansion. Check the exact regional model, price and network compatibility before deciding: specifications and availability can differ by market, and storage that cannot be expanded may matter more to some buyers than a small difference in a battery test.

A practical comparison checklist
- Compare endurance figures only when the test method and workload are identified; keep percentage-drain, lab-hour and manufacturer day estimates in separate categories.
- Check typical and rated capacity, but do not use mAh alone to declare a winner.
- Compare charging claims separately from runtime, and verify local charger requirements and box contents.
- Match display settings, network conditions and likely tasks as closely as possible.
- Include update support, storage, expansion, price, regional availability and network compatibility in the ownership decision.
Are there clear long-battery-life Android winners?
The available figures do not establish a complete, globally relevant ranking of Android phones by battery life. Tom’s Guide’s roundup says the A57 performs well on battery life while assessing the Pixel 10a as a stronger budget pick overall, but that is an editorial assessment rather than proof that either phone is the longest-lasting option. Tom’s Guide’s Android-phone roundup Use named alternatives as candidates to investigate, then compare results from the same test and confirm the device and configuration sold in your market.
