Samsung Galaxy Buds 4 and Galaxy Buds 4 Pro are currently under development. Fans are expecting these new earbuds to launch in early 2026, probably alongside the Galaxy S26 smartphones. Now, new information reveals the battery life of Galaxy Buds 4 and Buds 4 Pro cases.

According to the latest information via GalaxyClub, both earbuds will come with slightly larger charging cases. The Galaxy Buds 4 and Buds 4 Pro cases could have a rated battery of 515 mAh, with a typical capacity around 530 mAh.

This is a small upgrade compared to the Galaxy Buds 3 series, which had a 515 mAh battery. Even though the improvement is minor, it should mean users will need to charge the cases less often. Samsung may also improve the earbuds’ efficiency so they can play music longer on a single charge.

Recently, the codenames and model numbers of the new earbuds also leaked. Samsung calls the Galaxy Buds 4 “Handel” (model SM-R540) and the Galaxy Buds 4 Pro “Bach” (model SM-R640).

Moreover, some design details have also appeared online. Early sketches show that the Galaxy Buds 4 will keep the stem-style design from the Buds 3 series, with a few small changes. The stems may be slightly reshaped for better comfort and use.

The Galaxy Buds 4 series seems to bring small but meaningful improvements. Stay tuned for more information.

Google’s original Pixel Watch has just received its final official hug.

With Wear OS 6, Google brought system-wide Material You theming to the Pixel Watch. Here's how to pick your color and set it up.

Samsung is getting ready to launch its next wireless earbuds, the Galaxy Buds 4 and Galaxy Buds 4 Pro. The company seems to be giving this new lineup a unique and creative touch. Instead of using simple or color-based codenames like in the past, Samsung has chosen names inspired by classical composers.

According to information via Android Authority, the latest One UI 8.5 software revealed important details about these upcoming earbuds. In Samsung’s Buds Manager app, the Buds 4 are listed under the codename “Handel,” while the Buds 4 Pro are called “Bach.”

Both names come from famous German composers, which shows that Samsung is adding a touch of classical music flair to its new products. This is a new direction for Samsung, as older Galaxy Buds had much simpler codenames.

While the names Galaxy Buds 4 and Buds 4 Pro had already been seen before, this is the first time we’ve learned about their codenames.  These names are quite different from previous generations. For example, the Galaxy Buds 2 were called “Berry” internally, while the Buds 3, 3 Pro, and 3 FE used “Jelly,” “Paran,” and “Gemstone.”

The new musical codenames might hint that Samsung is aiming for a more elegant design or an improved listening experience. So far, there are no leaked images or official previews of the Galaxy Buds 4 series. Only some icons have appeared in the early One UI 8.5 builds, and it’s unclear if they represent the final design.

Still, it’s clear that Samsung is continuing to improve its popular audio lineup while also working on new products like the Galaxy XR headset. Stay tuned for more information.

Samsung is rolling out a new software update to the Galaxy Buds 3 and Buds 3 Pro with charging improvement. The company’s premium earbuds are receiving this firmware in South Korea, with expansion likely in the coming days.

October 2025 update for the Galaxy Buds 3 and Buds 3 Pro includes a “stability code related to charging operation.” Samsung recommends users install this new software to experience optimal performance and experience.

Galaxy Buds leverage on charging case to juice up their batteries. However, Samsung’s patch could mainly focus on the battery aspect to improve the charging. The battery life may also get a little boost, elevating the user experience.

In addition, the update should’ve also carried stability enhancements. Meanwhile, no new feature’s addition has been observed so far. If you find any new, kindly let us know through DM on X @thesammyfans.

Samsung also issued a general advice that the update’s content may vary by model, country and carrier. That said, the Global users may or may not receive charging improvements when the rollout begins outside Korea.

Firmware versions:

• R630XXU0AYJ1 – Galaxy Buds 3 Pro
• R530XXU0AYJ1 – Galaxy Buds 3

You can install the latest firmware through the Galaxy Wearable app. Open the application, head towards the device’s Settings, followed by Earbuds Software update, and hit the Download and install button.

Remember, the rollout has started only in South Korea. An expansion could take some time, so don’t panic if your earbuds don’t fetch the OTA.

Thanks for the tip, Aptivi!
