New leaks suggest the upcoming Galaxy Buds 4 lineup will feature mixed battery updates — good news for the Pro model, but a downgrade for the standard one. According to the leaks:
The Buds 4 Pro is expected to come with a 57 mAh battery per earbud, up from the 53 mAh in the previous-generation Buds 3 Pro.
The standard Buds 4, on the other hand, reportedly drop to a 42 mAh battery per earbud, down from the 48 mAh used in the Buds 3.
Early reports also hint that the charging case for Buds 4 / 4 Pro might get a slight increase in capacity — enough to help offset, at least partially, the smaller battery in the base model.
What This Means for Everyday Use
Pro users may benefit from better endurance. The increased capacity in the Buds 4 Pro suggests a likely boost in listening time, especially when using battery-hungry features like Active Noise Cancellation (ANC). For users who value longer playback and frequent use, this is a welcome change.
Base model users might see a drop — but not a big one. While the Buds 4 are losing battery capacity, Samsung’s rumored bump in charging case capacity could help compensate. If efficiency improvements in hardware/software hold up, actual battery life might stay acceptable.
Mixed strategy — differentiation via model tier. The divergence suggests Samsung is doubling down on making the Pro model a “premium choice” (bigger battery + presumably full feature set), while the regular Buds 4 may aim for a more budget- or efficiency-oriented balance.
What We Still Don’t Know
Because the data comes from leaks (firmware snippets, battery-spec listings), there remain many unanswered questions:
Will the real-world battery life gains/losses correspond exactly to the mAh values? (Battery life depends on usage, ANC, codec, volume etc.)
What about other features — ANC quality, audio performance, call quality, fit & comfort, durability? Battery is just one piece of the puzzle.
Will the charging case upgrade for the base model actually reach consumers? And how much of a difference will it make in total listening time?
Worth the Upgrade?
If these leaks hold true, the Galaxy Buds 4 Pro looks like a promising upgrade — especially for anyone using earbuds a lot, or relying on noise-cancelling and long listening sessions. The standard Buds 4 seem like a cautious, efficiency-focused step: fine for everyday users, but possibly less attractive if battery life is a priority.
As always, leaks are one thing — real-world performance may differ. I’ll be watching for full specs, battery tests, and user reviews.
