Today among the announcements of then new mid- and low-end SoC lineup Qualcomm also announced a new wearable platform dubbed the Snapdragon Wear 2500.
We don’t have many details on the platform and just interpreting what’s on the press release- but what seems to be happening here is that we’re looking at a new platform with supporting IC rather than a new SoC succeeding the Snapdragon 2100. In terms of disclosed specifications, the SW2500 matches the SW2100 as it uses a quad-core Cortex A7 as CPUs and uses an X5 modem.
The interesting thing about it is the way that Qualcomm describes the improvements – notably the 14% improved battery life of the platform. This seems to have been achieved by a new PMIC that reduces the quiescent current of the system when the SoC is sleeping. The new power amplifiers are said to improve peak power efficiency by 20%. The new power delivery is also noted to be 38% smaller than the predecessor which should allow vendors to optimise in terms of system PCB size and thus device dimensions.
The BSP (Board support package) provided by Qualcomm notably doesn’t outright run Android Wear, but rather an optimised version of Android O that is aimed at fitting the lower 512MB footprint and also had further software optimisations in terms of power management to shut off software components when not needed.
Given that Qualcomm is marketing this new platform for the kid watch segment, it’s likely that this is not the overdue “true” successor to the Snapdragon Wear 2100 that we’d be hoping for. While we’re awaiting confirmation, it also seems that the SoC on the new platform is the same one used in the 2100 so naturally the improvements are solely on the side of the supporting ICs such as the PMIC and RFFE, which would be a bit disappointing given the new naming for the platform.
The Snapdragon Wear 2500 is sampling right now and expected to come to market in the coming quarter, with Huawei expected to be the first company to come to market with a kids watch based on the platform.
