According to information obtained by the Android Authority from inside Google, the Pixel Watch used Exynos 9110 , a SoC for wearable devices made by Samsung, but the next-generation model Pixel Watch 2 is for Qualcomm wearable devices. It is said that it will adopt Snapdragon W5 Gen 1 which is a chip.
The Exynos 9110 has two cores (Arm Cortex-A53) with an operating frequency of 1.15 GHz, while the Snapdragon W5 Gen 1 has four cores with an operating frequency of 1.7 GHz. In addition, since the GPU core Adreno 702 is also installed, it seems that the graphics performance may improve dramatically.
The Android Authority claims that the biggest improvement is in the power efficiency of the chip, and in fact the Exynos 9110 that powers the original Pixel Watch was announced in 2018, and the process rules were released in 2017. 10nm process is adopted. As a result, ``Both the outdated manufacturing technology and outdated component design that Samsung incorporated into the SoC made the entire chip power inefficient,'' the Android Authority said.
On the other hand, the Snapdragon W5 Gen 1 is a relatively new SoC installed in smartwatches released in 2021 and 2022, and the process rule adopts Samsung's 4nm process, so it consumes less power than older chips. Efficiency has improved significantly. The Snapdragon W5 Gen 1 also adopts new technology to support low power states, so the Pixel Watch 2 is expected to dramatically improve battery life.
Qualcomm's chip for wearable devices also has Snapdragon W5 + Gen 1, but the only difference between this and Snapdragon W5 Gen 1 is ``with or without Qualcomm coprocessor QCC5100''. Sources say Google will replace this chip with a custom coprocessor based on the same NXP chip found in the original Pixel Watch.
One of the most important upgrades in Pixel Watch 2 is the adoption of ultra-wideband (UWB). The Pixel Watch 2 will have an NXP SR100T UWB module, which is expected to improve the accuracy of Find My Device .
UWB chips are also useful for technologies such as opening car keys with smartwatches. This kind of technology is already supported by BMW, and automakers such as GM, Honda, Volkswagen, and Hyundai are also developing it for implementation. UWB chips are installed in some Android smartphones, but not all Android devices. However, if Pixel Watch 2 is equipped with a UWB chip, it will be possible to unlock the car even if the smartphone side does not have a UWB chip.
In addition, the Android Authority points out that the UWB chip may allow media playing on Pixel Watch 2 to be seamlessly transferred to other UWB-enabled devices such as Pixel Tablets.
The following media transfer is also possible with Pixel Watch 2.

In addition, the battery capacity of the Pixel Watch 2 has increased, and it seems that the battery capacity will be increased from 294mAh of the original Pixel Watch to 306mAh. The increase in battery capacity is very small, but as mentioned above, the chip improvements are expected to greatly improve battery life.
In addition, the basic specifications of the display are the same resolution as the first model, 384 x 384 pixels, and the size is 1.2 inches circular OLED, but it will be changed from the Chinese manufacturer BOE to Samsung. pattern. According to the person who provided information to the Android Authority, it seems that no further changes have been confirmed in the display, but the Android Authority said that the brightness and energy saving performance of the display may improve due to the change in the manufacturer. pointing out.
In addition, Pixel Watch 2 will be equipped with Wear OS 4 based on Android 13. As a result, it seems that terminals using the old version of Wear OS can upgrade the OS in the background. However, the drawback is that Wear OS 4 almost doubles the required storage capacity, making it impractical for low-end smartwatches.

Pixel Watch 2 is being developed under two different codenames, of which the LTE compatible version is called 'Eos' and the Wi-Fi version is called 'Aurora'. Also, the Pixel Watch 2 has three model numbers: G4TSL, GC3G8, and GD2WG, but this is to have models available in some regions, and 'Google has announced the Pixel Watch 2 may be preparing to enter the Indian market,” reports the Android Authority.
