Google is rolling out an upcoming software update starting on January 8, 2025, for the Pixel 4a phones. The new update aims to improve battery performance and stability. However, this may come with a reduction in battery capacity and charging time.
The update, which is still based on Android 13, will not affect all Pixel 4a devices equally. While some owners can expect changes like reduced charging performance or altered battery-level indicators, others will remain unaffected.
Affected users are eligible for a free battery replacement at participating repair centers worldwide, including the US, Canada, UK, Germany, Singapore, and India. The offer is limited to those whose devices have suffered from physical damage such as liquid damage or exposure to sharp objects. For out-of-warranty damages like display cracks, there may be additional fees.
If replacement is not possible, eligible users can opt for a $50 USD payment or a $100 USD hardware discount code towards purchasing another Pixel phone on the Google Store.
