Android 14 stable update has reportedly fixed heating and battery life issues on the Google Pixel 7 and Pixel 6 devices.
Google hasn't mentioned anything about fixing overheating and battery issues on the Pixel 6 and Pixel 7 in the Android 14 changelog. It is possible that the brand may have tweaked the CPU scheduler to reduce the usage of the big CPU cores. This may have led to an impact on battery life and the amount of heat the chip generates.
Whatever may be the case, this is a welcome change for Pixel 6 and Pixel 7 customers. It is a good sign that Google is working on improving user experience even after it just introduced the Pixel 8 series. The Android 14 enhancements should also bring noticeable improvements to the Pixel Fold as well but we need more user reports to tell for certain.
Do note that Android 14 will not magically take away all the shortcomings of the Pixel 6 and Pixel 7 as Tensor chipsets are usually power-hungry and the phones might still get warm on heavy usage or while gaming. However, the issues should be optimised to a certain level.
