A new report details the expected battery and charging features of the upcoming Galaxy S26.

Samsung's Galaxy S26 series is anticipated to bring significant changes. Besides improvements to its software, display, and processor, the focus is expected to be on improved battery performance and charging capabilities.

Rumored upgrades include stacked or silicon-carbon batteries, Qi 2.2 magnetic wireless charging, and increased wired charging speeds for all models.

The lineup is expected to consist of the Galaxy S26 (or S26 Pro), the S26 Plus, the S26 Ultra, and the thin Galaxy S26 Edge, each providing different sizes, battery capacities, and charging features.

Here's an overview of the expected battery and charging capabilities for each model.

Will the Galaxy S26 have improved battery performance?

Galaxy S26 and S26 Plus

Likely, yes.

The base Galaxy S26 might feature a 4,300 mAh battery, an increase from the S25's 4,000 mAh, while the S26 Plus will likely keep its 4,900 mAh battery. Efficiency gains should come from the Snapdragon 8 Elite Gen 5 or Exynos 2600 chips (both using a 3 nm process) and new M14 OLED panels, designed to consume less power while providing higher brightness.

These enhancements, along with One UI 8.5’s optimized background-task management, should translate to longer battery life compared to the S25 series, even without larger batteries.

Galaxy S26 Ultra

The Ultra version will probably offer the most battery life in the series, even if it maintains the same 5,000 mAh battery. Any increase in battery life will likely come from greater power efficiency.

An improved cooling system and the 3 nm Snapdragon 8 Elite Gen 5 chip are expected to help maintain performance and reduce thermal throttling, preserving battery life during intensive tasks.

Samsung’s updated AMOLED panel tech should also decrease power consumption, resulting in a noticeable improvement over the S25 Ultra’s battery performance.

Galaxy S26 Edge

The priority for the Edge is a slim design. With an expected thickness of only 5.5 mm, battery life will likely be its biggest challenge.

However, Samsung might include a 4,200 mAh battery (compared to 3,900 mAh in the S25 Edge). With the efficient Snapdragon 8 Elite Gen 5 and AI-optimized power management, the S26 Edge should offer longer battery life than its predecessor while maintaining its slim profile.

Expected Battery Capacity:

* Galaxy S26: 4,300 mAh

* Galaxy S26 Plus: 4,900 mAh

* Galaxy S26 Ultra: 5,000 mAh

* Galaxy S26 Edge: 4,200 mAh

Will the Galaxy S26 offer wireless charging?

Galaxy S26 and S26 Plus

Yes, both models are expected to support 15W Qi 2.2 wireless charging. Magnets inside the phones should allow seamless alignment with Qi 2.2 chargers and accessories, improving upon the S25 series' "Qi2 ready" status.

Galaxy S26 Ultra

The Ultra will also feature Qi 2.2, providing better charging efficiency and reduced heat, important for a phone with a vapor-cooled design. Wireless charging speeds will probably remain at 15W, even for the Ultra.

Galaxy S26 Edge

Yes, this upgrade is especially significant for the Edge. It is expected to be the first ultra-slim Galaxy to have built-in magnets for Qi 2.2 charging, supporting up to 15W wirelessly.

Will the Galaxy S26 have reverse wireless charging?

Galaxy S26 and S26 Plus

Yes. Wireless PowerShare (5W) should be available, useful for charging accessories like earbuds or smartwatches.

Galaxy S26 Ultra

Yes. The Ultra will likely have Wireless PowerShare at 5W.

Galaxy S26 Edge

It's unclear. While the S26 Edge is rumored to offer wireless charging, there is currently no information about reverse wireless charging.

What charger will the Galaxy S26 use?

Galaxy S26 and S26 Plus

Both phones will likely support USB Power Delivery (PD 3.0 with PPS), allowing the use of Samsung’s Super Fast Chargers or third-party PD/PPS chargers from brands like Anker or Ugreen.

* S26: 25W max

* S26 Plus: 45W max

A USB-C cable will likely be included, but not a charger.

Galaxy S26 Ultra

The Ultra is expected to support 60W wired charging using the PD/PPS standard. It should work best with Samsung’s next-generation 60W adapter but will also be compatible with standard PD chargers.

Galaxy S26 Edge

The Edge will likely be limited to 25W wired charging. While Samsung’s 45W Super Fast Charger or any PD/PPS charger can be used, the S26 Edge will only draw a maximum of 25W.

How fast will the Galaxy S26 charge?

Galaxy S26 and S26 Plus

* S26: 50% in approximately 30 minutes (25W)

* S26 Plus: 60% in approximately 30 minutes (45W)

Wireless charging at 15W should reach full charge in about 1 hour and 30 minutes.

Galaxy S26 Ultra

If the rumored 60W charging is accurate, the S26 Ultra could reach 50% in about 20 minutes and achieve a full charge in about 45 minutes. This would be a notable improvement over the S25 Ultra’s 57-minute charging time. Wireless charging will likely remain at 15W, taking around 2 hours for a full charge.

Galaxy S26 Edge

The S26 Edge should reach 50% in about 30 minutes. Wireless charging (15W) could take approximately 2 hours and 10–15 minutes for a full charge.
