Samsung may finally fix its 45W ‘slow charging’ issue in S26 Ultra!
Samsung might finally be listening to fans who’ve been complaining about charging speeds that feel stuck in 2019. A new firmware leak for the Galaxy S26 Ultra has revealed something exciting: 60W fast charging is likely on the cards. And after years of criticism, that’s a seriously welcome upgrade.
This news comes straight from an early firmware build of the S26 Ultra, which also offers the first real clues about the device’s software and charging capabilities. While Samsung hasn’t officially confirmed anything yet, the new evidence is strong enough to treat as a near-official teaser.
Charging complaints around the Samsung's flagships are loud and clear
Let’s be honest—Samsung’s charging speeds have been way behind the curve. The Galaxy S25 Ultra was supposed to support 45W Super Fast Charging 2.0, but in reality, many users found themselves stuck at 15W or less due to bugs related to Samsung’s 5A cable. Even with the official 45W adapter, the speeds were inconsistent and often required switching to a 3A cable or disabling fast charging altogether.
Meanwhile, brands like Xiaomi, OnePlus, and Realme are flexing 80W to 120W fast charging on their flagships, powering up in 30-35 minutes or less. The Realme GT 7, for example, really impressed us in this regard. So, Samsung sticking to 45W—especially when it didn’t always work—felt like a major letdown.
The firmware confirms a long-awaited wattage boost
Thankfully, it looks like the tide is turning. The newly discovered Galaxy S26 Ultra firmware includes references to 60W charging support. The discovery was made by tech insider Erencan Yılmaz and shared on X (formerly Twitter), backed by a screenshot from the firmware code itself. It’s the first real sign that Samsung is finally ready to ditch the outdated 45W ceiling.
And it aligns perfectly with an earlier leak by trusted tipster Ice Universe, who mentioned that the S26 Ultra would come with a 5,000mAh battery, a slimmer frame under 0.31 inches, and the new 60W fast charging standard. We hope the Galaxy Z Fold 7 also gets the same treatment.
One UI 8.5 also confirmed for the S26 series
The same firmware build also gives us a peek into the software side of things. The Galaxy S26 series is expected to ship with One UI 8.5, based on Android 16. This will likely act as a bridge between the current One UI 8 (seen on the Fold 7 and Flip 7) and the eventual One UI 9 update based on Android 17, expected to land in mid-2026.
The 8.5 version is expected to focus on new Galaxy AI tools, polish up the UI, and hopefully iron out the bugs that plagued the S25’s charging experience.
Final thoughts
If Samsung does go ahead with 60W charging, the Galaxy S26 Ultra could finally stop being the slowpoke of the flagship world. It’s not just about faster top-ups—it’s about keeping up with what premium users expect in 2025. And judging by this firmware, Samsung might finally be ready to deliver.
