According to a fresh claim, Samsung’s forthcoming Galaxy Watch 5 lineup may include a new ‘Pro’ model. Samsung released two different Galaxy Watch 4 models last year. This year, Samsung will expectedly introduce a new series. It will provide buyers with an upgraded design and functionality.
Samsung’s future smartwatch’s codenames surfaced within the Samsung community forums. These codenames suggest that a Galaxy Watch 5 “Pro” variant is in development. The finalized names of the variants may vary. “Heart-S,” “Heart-L,” and “Heart-Pro” are the three codenames as reported by GalaxyClub. It is indeed difficult to decipher information from the codenames themselves, but the source has linked these codenames to model numbers.

Galaxy Watch 5 variants
As per the source, the codename for model SM-R90x is Heart-S, while the codename for model SM-R91x is presumably Heart-L. Additionally, the codename for model number SM-R92x is Heart-Pro.
The Heart-S codename is presumably the given name for the most compact 2022 smartwatch variant. Its size will range from 40mm to 42mm. The Heart-L codename presumably corresponds to the larger Galaxy Watch 5 model. Additionally, its size will be 44mm or 46mm.
The “Heart-Pro” is the most advanced variant of the three. Earlier, “Galaxy Watch 5 Pro” was the expected name of this variant. It’s safe to say that whichever name ultimately comes up, this watch will incorporate advanced features.
A massive 572mAh battery will allegedly power the Pro version of the smartwatch. This is an improvement, up from the 361mAh battery capacity of the 46mm Galaxy Watch 4 Classic. To put into perspective, there will be an almost 60% increase in capacity on the upcoming watch. A 572 mAh battery would probably provide less than two days of battery life for most users who will use it intensely. Additionally, if users do not turn on all the features, the battery will probably make it past 48 hours of use with a battery of this capacity. The non-Pro models are also expected to get equipped with batteries that have a long battery life.
Samsung will presumably equip the smaller “Heart-S” Galaxy Watch 5 variant with a 276 mAh rated capacity battery. This is an improvement when compared to the 247 mAh, 40mm non-Classic Galaxy Watch 4.
