**Speculations Indicate S26 Ultra May Not Receive Significant Battery Enhancement After All**
Speculations regarding the Galaxy S26 Ultra have been prevailing for several days. We’ve already encountered S26 battery leaks that suggest Samsung isn’t prepared to implement silicon-carbon just yet, and now it appears that hints of Samsung potentially adopting quicker charging rates could merely be a distant wish for Galaxy enthusiasts.
These speculations initially began to gain momentum in July, when a prominent leaker, Ice Universe, posted on X that the Galaxy S26 Ultra was “100% confirmed” to exceed the 45W fast charging capabilities that Samsung has maintained for a couple of years. At that time, Ice Universe did not provide specific details on what those new speeds would entail, but subsequent reports expanded on the topic and appeared to support it.
Those additional reports, which were disseminated by Sam Mobile, indicated that leaked firmware documents suggested 60W charging speeds would arrive with the S26 Ultra upon its debut in 2026. Nonetheless, that does not seem to be the scenario, as fresh reports from Sammy Guru imply that the S26 Ultra might continue to be restricted to the 45W charging speeds seen in the Samsung Galaxy S25 Ultra and prior Galaxy models. According to Sammy Guru’s findings, certifications from Chinese regulators indicate that the S26 Ultra has only been approved to charge at rates of up to 45W.
**The narrative keeps evolving**
Now, it is noteworthy to mention that the Chinese certifications do not explicitly mention the S26 Ultra by its name. However, leaks from the GSMA database have provided us with the model number for the S26 Ultra, which is SM-S948. With this information, we can observe in the certification here that the Galaxy S26 Ultra is solely rated in China for 45W charging speeds.
This latest leak, therefore, suggests that prior speculations regarding the S26 Ultra being guaranteed to feature faster charging are unfounded. It is still quite plausible that Samsung could be sending a distinct variant of its phone to China — as regulatory requirements can differ from one nation to another. However, there is no present history of the company implementing such significant alterations to its primary flagship phone lineup in the past, so this would be an entirely new approach for the company.
Naturally, there is still much to anticipate with the Galaxy S26, including some significant design updates to the S26 lineup that have surfaced over the last few weeks, potentially featuring more rounded corners on the S26 Ultra.
