In 2021, Google launched its first in-house Tensor chip with the Pixel 6, aiming to bring advanced AI and machine learning features directly to the device. The ambition was to turn smartphones into mini powerhouses capable of handling tasks that typically required cloud computing. This set off Google’s journey to infuse AI deeper into its Pixel lineup, moving quickly from one Tensor generation to the next.

Today, the Pixel 9 boasts the latest Tensor G4 chip, marketed as Google’s “most powerful chip yet, designed to handle Google’s advanced AI.” With 12GB of RAM, the Pixel 9 promises speed and a smooth user experience. Yet, these high-performance features seem to come at a cost. Many users are finding that the basics—like battery life and thermal handling—are falling short.

A report from Android Authority recently highlighted that overheating has become the leading reason for Pixel returns, with 28% of customer complaints citing excessive heat as a significant issue. Internal documents show Google’s acknowledgment of this, listing “Thermals – #1 reason for Pixel returns” and indicating that thermal limits may be set too high, especially for power-intensive tasks. The report also notes that better thermal management could greatly enhance user satisfaction.

Battery life is another major complaint. Google markets the Pixel 9 as having a “long-weekend battery,” designed to last over 24 hours and up to 100 hours with Extreme Battery Saver. However, real-world usage seems to fall short, with many users expecting closer to 36 hours on a single charge. For today’s smartphone users, dependable battery life is essential, and the Pixel 9’s performance in this area has left some users disappointed.

It’s likely that the Tensor chip’s high demands for AI processing contribute to these issues, drawing more power and generating more heat than average smartphone tasks. While the AI capabilities of the Tensor chip are impressive, balancing these features with essential factors like battery efficiency and heat control is a challenge that Google may need to address moving forward.

With the anticipated release of the Tensor G5 on the Pixel 10 in 2025, and the G6 slated for the following year, Google has a chance to improve in these key areas. As the company continues to innovate with AI-driven experiences, ensuring that the fundamentals—like battery life and thermal management—are up to par could be vital to meeting user expectations and satisfaction.
