Samsung Galaxy S26 Ultra Brings a Battery Boost, Just Not a Big One

Monday, 24 November 2025 at 02:55

Samsung is moving in backstage to prepare its Galaxy S26 series for release. As usual, the lineup will bring the Galaxy S26, S26+, and the S26 Ultra. Of course, the Ultra will remain the highest flagship the lineup offers. We expect some improvements to come with the Samsung Galaxy S26 Ultra, and a new leak confirms a slight jump in the battery capacity. We're living in the era of flagships with large batteries, breaking the boundaries to 7,000mAh and promising 8,000mAh batteries soon. Despite this, Samsung will continue its conservative approach, increasing the S26 Ultra's battery to 5,200mAh from the S25 Ultra's 5,000mAh capacity.

Samsung Galaxy S26 Ultra Tipped With a 5,200mAh Battery

The leak came from China and confirms the Samsung Galaxy S26 Ultra will pack a 5,200mAh battery. We don't know if this battery upgrade will be noticeable in the day-to-day. It's not a big jump, but it's still a step in the right direction. Most of the past Ultra models had a 5,000mAh capacity, and the new bump suggests that Samsung is watching the competition with its Si-C technology. We believe the Korean firm will not adopt the Si-C tech at this point, as it tends to play it safe with anything involving battery and charging.

Interestingly, the new rumor contractics a Chinese certification from August, which revealed the Samsung Galaxy S26 Ultra would pack a rated capacity of 4,885mAh. There is a considerable difference between this and 5,200mAh. So we don't think that's the usual typical capacity for advertisements. The old leak indicated a typical capacity of 5,000mAh, which is more believable considering the 4,885mAh rated capacity.

Rumors Point To 60W Fast Wired Charging

Since the old leak is based on Chinese certification, and the new one in insider's info, we have to digest the news with a pinch of salt. We will have to wait for more sources to confirm the bump in the capacity. As far as the charging is concerned, some rumors have been pointing to a 60W wired charging and 25W wireless charging for the S26 Ultra. That would be a considerable enhancement. After all, Samsung has been sticking with 45W for years in the Ultra lineup. The S26 and S26 Ultra will charge even slower at the usual 25 Watts.
