Galaxy S26 Ultra rumours: battery & charging that don't satisfy

Apparently, the latest leaks about the Samsung Galaxy S26 Ultra bring two new "disappointing" - based on expectations - details: battery and charging.

Around 5000 mAh is again the most likely capacity - same as the S20/S23/S25 Ultra models. Tipster PandaFlash (PandaFlash Pro) reports that Samsung will probably not increase the battery above 5 400 mAh, again opting for the conservative route

Some others -even earlier- had talked about 5500 mAh , but there are no indications that this will be cut or confirmed in the final model.

Samsung seems to be continuing with 45 W wired charging, meaning without the big jump that other companies have made (90-150 W). From the leaks it is included that the charging speed will not be increased either.

Why "disappointment"?

Analysts cite two reasons:

• Inertia compared to the Chinese market that already puts 6 000-7 000 mAh units.
• Samsung's central choice to keep the models thin - so less space for more battery.

The S26 Ultra is in the early leaks stage, so nothing is official yet. Samsung hasn't confirmed either the official capacity or charging speeds.

Although the S26 Ultra looks powerful in terms of AI, cameras and design, the battery and charging will probably NOT be upgraded substantially compared to the S25 Ultra.
