Time to check the ol' phone drawer Google Pixel 4a gets an unexpected update: Lower battery life It's intentional, and eligible users can get cash or free battery replacements.

This week, it will receive a rather uncommon oneone that intends to lower its reported battery life.The Pixel 4a, released in the summer of 2020, was discontinued at the end of 2022. It received its last official software update in the summer of 2023, followed by a surprise security update in November 2023. Throughout 2024, there were no updates. This week, owners of the 4a (and likely many former owners) are getting a new update, along with an email titled "Changes coming to your Pixel 4a."The email addresses "an upcoming software update for your Pixel 4a that will affect the overall performance and stability of its battery." The automatic software update to Android 13 "introduces new battery management features to improve the stability of your device," which will "reduce your battery's runtime and charging performance."Google goes into more detail on a support page about the "Pixel 4a Battery Performance Program," noting that only some "Impacted Devices" will see the reduced capacity and charging performance. Those with such devices (determined by a survey) have three options beyond just taking the hit: sending their phone in for a free battery replacement, receiving $50 (or the non-US equivalent) payment, or getting $100 toward a new Pixel phone from the Google Store. Those with impacted phones have one year from the scheduled software update on January 8, 2025, to choose an "appeasement option."Google has skipped the details on why "available battery capacity and charging performance" are taking a hit and what makes a device "Impacted," stating only that the company has "determined that certain Pixel 4a phones" need to "improve the stability of their battery's performance." But there are some educated guesses to be made. Given that the batteries in most Pixel 4a phones are somewhere between two to five years old and some of them were likely kept in capacity-diminishing low states of charge, many are in rough shape.Being in such rough shape, they may not provide all the power demanded by the phone, especially in notably cold or hot conditions. By constraining the battery levels at which the phone can operate, Google can prevent phones from dealing with inconsistent power that can result in unexpected behavior or shutdowns. It's akin to what happened with older iPhones being slowed down in late 2017, except Google is coming out in front of its software fix and compensating users for the change rather than waiting for it to play out in the courts.Ars has contacted Google for comment and will update this post if we receive a response.Kevin PurdySenior Technology ReporterKevin PurdySenior Technology Reporter Kevin is a senior technology reporter at Ars Technica, covering open-source software, PC gaming, home automation, repairability, e-bikes, and tech history.
