Tipster claims the Samsung Galaxy S26 Ultra's battery capacity will be less than 6,000 mAh

A recent report coming out of South Korea claimed that Samsung was planning to pack next year's Galaxy S26 series with Si/C batteries, possibly with a capacity of up to 7,000 mAh. However, a tipster claims the Samsung Galaxy S26 Ultra won't even have a 6,000 mAh battery.

The tipster was quite confident in their claim and said they would delete their X (previously called Twitter) account if the Galaxy S26 Ultra came with a 7,000 mAh or even a 6,000 mAh battery.

Furthermore, citing five sources, the tipster said Samsung's test lab only has a battery with a maximum capacity of 5,550 mAh. But that's probably the typical capacity since the actual capacity is 5,396 mAh.

I’ll delete my Twitter account if Samsung gives the Galaxy S26 Ultra a 7000mAh or even a 6000mAh battery I bet. 🙂

"Based on my Five Sources, the internal Samsung Test Lab only seem to have a Capacity of Max 5500mAh not more".

It's worth mentioning that this tipster didn't reveal if they were referring to Si/C type batteries or the Li-Ion batteries we have on the Galaxy S25 lineup.

Even it’s not complete 5500mAh it’s like 5396mAh.

Anyway, the launch of the Samsung Galaxy S26 lineup is about a year away, so it's best to wait for this information to be corroborated by multiple sources. We'll definitely hear a lot about the S26 series in the coming months.
