Galaxy S27 Ultra to Charge Faster Without More Power: Samsung Tunes 60W and Tests AI Against Lens Flare

Samsung has no plans to join the aggressive race to hundreds of watts with its Chinese rivals, but it does intend to cut the time its next flagship spends plugged into a wall outlet. According to fresh leaks, the Galaxy S27 Ultra will keep its wired power limit at 60W, yet it will charge faster than its predecessor thanks to retuned power algorithms. At the same time, the company’s engineers are testing a new neural-network camera feature designed to solve a long-standing hardware problem with stray light flares.

According to tipster WalleGalaxy, whose information is corroborated by the specialist outlet SamMobile, the South Korean developers have changed the current delivery profile. During the first half of the charging cycle, the controller will be able to hold values at 55–56W more steadily, without dropping the level because of early heat buildup. As a result, the phone will replenish energy roughly 2–3% faster than the Galaxy S26 Ultra with absolutely identical rated adapter specs.

A New 5700 mAh Battery and an Efficiency Gain

A couple of percentage points seems insignificant only at first glance. The point of the optimization becomes clear against the backdrop of a larger battery capacity. A database entry from China’s 3C regulator previously revealed a battery for the S27 Ultra with a rated capacity of 5534 mAh. In commercial specs, that translates to roughly 5700 mAh of typical capacity — versus the classic 5000 mAh in the S26 Ultra.

Instead of raising peak wattage in a way that would endanger cell longevity, Samsung focused on the useful area under the power curve. If internal tests hold up at release, the flagship will be able to charge a noticeably larger battery faster than the previous model charged a standard one.

A Software Fix for Nighttime Lens Flare

The second major novelty concerns mobile photography. According to tipster kro, as published on ITHome, the company is testing a specialized algorithm to remove lens flare. This refers to the green dots, halos and streaks of light that inevitably appear in a lens’s optical system when shooting streetlights, headlights or bright sun.

In test builds of the system, the neural network removes such defects almost without a trace already at the final post-processing stage of an image. It is not yet known whether this feature will remain exclusive to the S27 Ultra thanks to the capabilities of the new processor, or whether it will later arrive in One UI updates for previous lineups.

The official debut of the Galaxy S27 series is expected in early 2027. Until the announcement, Samsung is not commenting on leaks, and the power management algorithms and test camera features may still be adjusted by the developers.
