Google's Mandatory Software Update Kills Battery Life on Pixel 4a and 6a Models

Google has been quietly throttling battery life on two of its Pixel models, the Pixel 4a and Pixel 6a. The company's 'Battery Performance Program' was first introduced for the Pixel 4a in early 2025, citing a need to improve battery stability.

The program affected certain devices, reducing their available battery capacity and charging performance. This was not limited to just older phones; newer models like the Pixel 9a were also affected by the mandatory software update that reduced battery life and charging speeds.

For users of impacted devices, Google offered a range of 'appeasement' options, including free battery replacements, cash payments, or Google Store credits. However, these remedies only lasted for one year, leaving users who missed out with no choice but to live with the reduced performance of their batteries.

The Pixel 7a is another example of Google's ongoing issues with battery reliability. In April 2025, a support document outlined an 'Extended Repair Program' for the device due to unexpected battery swelling, which can pose safety risks.
