TL;DR New strings of code provide updated information on the battery capacities for the Galaxy Buds 4 and Buds 4 Pro.
The Buds 4 Pro will see a significant jump in typical battery capacity compared to the Buds 3 Pro, but the Buds 4 will see a minor decrease.
Another update suggests that the previously reported head gesture feature may be limited to Bixby for answering yes-or-no questions.
The next generation of Samsung’s Galaxy Buds is on the way. Over the last few months, we have been uncovering a variety of information about the Galaxy Buds 4 and Buds 4 Pro. Recently, we spotted a few details about the battery capacities and a new “Head Gestures” feature hiding in strings of code of a leaked One UI 8.5 build. Since discovering this information, these strings have been updated to provide more details and context.
Back in early December, we learned that the Buds 4 would have a battery capacity of 42mAh, while the Buds 4 Pro would come with a 57mAh battery. At the time, the words “typical capacity” appeared next to these numbers, leading us to believe these were the typical battery sizes for both models. However, a recent update reveals these are the rated capacities, rather than the typical capacities. It turns out that the typical capacity for the Buds 4 is 45mAh, while we can expect a 61mAh capacity for the Buds 4 Pro.
If you’re wondering what the difference is between typical and rated capacity, here’s a quick explanation. The typical capacity refers to the average actual capacity of a battery in a production batch, based on the manufacturer’s specified charging and discharging conditions. Rated capacity, on the other hand, refers to the guaranteed minimum capacity that a battery will have.
For comparison, the Galaxy Buds 3 have a typical battery capacity of 48mAh, while the Buds 3 Pro features a 53mAh battery. That means the Buds 4 will still see a slight dip in capacity compared to the last generation. However, the Pro version of the earbuds is receiving a significant boost. This would actually bring the capacity back up to the same level as the Buds 2 Pro, which also has a typical capacity of 61mAh.
