According to Google’s internal documentation, the main reason for the Pixel’s return is overheating. The company continues to address heat issues in future Tensor chips, particularly the upcoming Tensor G6. Leaked slides also show that battery life is another major area of concern for Google.
Google Tensor is a series of SoCs developed by Google specifically for its Pixel smartphones. Unlike other smartphone manufacturers that use off-the-shelf processors from Qualcomm or Samsung, Google developed Tensor in-house. This allows the chip to be optimized for the specific needs of the Android operating system and Pixel software.
