Battery life remains one of the most important features to consider when buying a premium smartphone, particularly for Samsung users who spend long hours streaming videos, browsing the internet, using social media, gaming or working on their phones.
Samsung’s high-end Galaxy range includes several devices with large-capacity batteries, while newer processors and software optimisation are designed to improve power efficiency.
Samsung’s current flagship range includes the Galaxy S26 series, while premium foldables such as the Galaxy Z Fold7 offer a different combination of battery capacity, performance and screen size. Samsung lists the Galaxy S26 Ultra with a 5,000mAh battery and up to 31 hours of video playback, while the S26+ has a 4,900mAh battery and the same claimed video playback figure.
Here are 10 high-end Samsung phones worth considering if battery life is a priority.
1. Samsung Galaxy S26 Ultra – 5,000mAh
The Galaxy S26 Ultra sits at the top of Samsung’s traditional smartphone range and combines a 5,000mAh battery with a large 6.9-inch display and flagship hardware.
Samsung says the phone can provide up to 31 hours of video playback on a single charge. The device also uses Samsung’s latest processor and power-management technologies to improve efficiency.
Its 5,000mAh capacity remains one of the largest batteries available on Samsung’s flagship S-series phones.
2. Samsung Galaxy S26+ – 4,900mAh
The Galaxy S26+ offers almost the same battery capacity as the Ultra model, with a 4,900mAh battery.
Samsung rates the phone for up to 31 hours of video playback, making it one of the company’s strongest options for users who want long battery life without buying the Ultra model.
It features a 6.7-inch display and is powered by the Snapdragon 8 Elite Gen 5 for Galaxy in markets where that configuration is offered.
3. Samsung Galaxy S25+ – 4,900mAh
The Galaxy S25+ remains a high-end option for users looking for a large battery in a conventional flagship phone.
It packs a 4,900mAh battery, matching the capacity of the newer Galaxy S26+.
Its combination of a large display, flagship processor and sizeable battery makes it suitable for users who frequently stream content, browse social media or use demanding applications.
Samsung’s battery guide lists the S25+ among its Galaxy phones with a 4,900mAh battery.
4. Samsung Galaxy S24+ – 4,900mAh
The Galaxy S24+ is another premium Samsung phone built around a 4,900mAh battery.
Although it is an older generation than the S25+ and S26+, its battery capacity remains competitive with newer flagship models.
For buyers looking for a premium Galaxy phone without necessarily purchasing the latest generation, the S24+ can offer a combination of flagship features and substantial battery capacity.
Samsung’s battery guide lists the S24+ alongside the S25+ and S26+ in the 4,900mAh category.
5. Samsung Galaxy S25 Ultra – 5,000mAh
The Galaxy S25 Ultra comes with a 5,000mAh battery, placing it among Samsung’s largest-capacity conventional smartphones.
It was designed as Samsung’s flagship Ultra device before the arrival of the S26 Ultra, with a large display, advanced cameras and high-end processing hardware.
The 5,000mAh capacity means the S25 Ultra remains an option for buyers who want a premium Samsung phone with a large battery without moving to a foldable.
Samsung’s current device listings continue to show the S25 Ultra with a 5,000mAh battery.
6. Samsung Galaxy S24 Ultra – 5,000mAh
The Galaxy S24 Ultra also features a 5,000mAh battery.
Its large battery is paired with a 6.8-inch display and flagship hardware, making it particularly suited to users who need a premium device for photography, video, gaming and productivity.
While newer Galaxy models have arrived, the S24 Ultra remains part of Samsung’s high-end Ultra family and has one of the company’s largest battery capacities.
7. Samsung Galaxy Z Flip7 – 4,300mAh
Samsung’s foldable phones traditionally have smaller batteries than the company’s largest S-series models, but the Galaxy Z Flip7 increased its capacity to 4,300mAh.
Samsung says the Flip7 can provide up to 31 hours of video playback, despite its compact foldable design.
The phone therefore offers an interesting combination for users who want a premium foldable without giving up as much battery capacity as some earlier compact Galaxy foldables.
8. Samsung Galaxy Z Fold7 – 4,400mAh
The Galaxy Z Fold7 features a 4,400mAh battery.
Unlike the conventional Galaxy S phones, the Fold7 has a large foldable inner display, which gives users a tablet-like screen for multitasking, entertainment and productivity.
Samsung rates the Z Fold7 for up to 24 hours of video playback. Its battery capacity is smaller than that of the Ultra S-series phones, but its foldable form factor gives it a different advantage for people who prioritise screen size and multitasking.
9. Samsung Galaxy S26 – 4,300mAh
The standard Galaxy S26 comes with a 4,300mAh battery, which is an increase over the 4,000mAh battery used in the Galaxy S25.
Samsung says the S26 can deliver up to 30 hours of video playback.
Despite having a smaller battery than the S26+ and S26 Ultra, the standard S26 combines its capacity with a smaller 6.3-inch display, which can help make it a practical choice for people who want a more compact flagship.
10. Samsung Galaxy S25 Edge – 3,900mAh
The Galaxy S25 Edge is included for buyers who prioritise Samsung’s premium design and thin form factor alongside flagship performance.
It has a 3,900mAh battery, making it smaller than the batteries found in the S25 Ultra and S25+.
Samsung’s battery guide places the S25 Edge in the 3,900mAh category, below the 4,000mAh S25 and 4,900mAh S25+.
Samsung’s published battery guide confirms these capacity groupings, although actual battery life varies according to factors such as network conditions, display brightness, applications, settings and usage patterns.
