⚠️ Pixel 6a Battery Downgrade Coming Soon – Here's Why

June 2025: Google is set to push a mandatory software update for Pixel 6a users that will reduce battery voltage and charging performance. The reason? Overheating issues and **spontaneous battery fires** reported in some units after extended usage.

🔥 What’s Causing the Issue?

The problem is related to **battery aging and thermal instability**. After around 400 charge cycles, lithium-ion batteries begin to degrade, and thermal stress builds up—especially during fast charging or in warm environments. Google confirmed that multiple Pixel 6a units suffered **thermal runaway events**—a dangerous chain reaction that can lead to swelling, fire, or explosion.

This is not unprecedented—last year, Pixel 4a users saw similar voltage-limiting updates when overheating issues were detected post-warranty.

⚙️ What Is Google Doing About It?

In a statement tied to the Android 16 QPR1 Beta, Google confirmed a system-level update is rolling out:

A subset of Pixel 6a phones will require a mandatory software update to reduce the risk of potential battery overheating. The update will enable battery management features that will reduce capacity and charging performance after the battery reaches 400 charge cycles.

Though specific voltage figures haven’t been disclosed yet, if it mirrors the Pixel 4a update (which dropped max voltage from 4.45V to 3.95V), this could result in up to **50–60% reduced charging capacity**, directly impacting daily battery life.

🧪 How to Check If You’re Affected

Google says the update will target only devices with **400+ charge cycles**. To check your battery health:

• Go to Settings > Battery > Battery health
• If a warning is displayed, you're likely eligible for the update

If you're seeing battery swelling, abnormal heat while charging, or sudden shutdowns, you should stop using the device and **visit a Google-authorized service center**.

🔁 Free Replacements for Pixel 7a Users

Interestingly, Google is also offering **free battery replacements** for Pixel 7a users facing battery swelling. While the Pixel 6a fix involves limiting performance, the 7a is getting physical replacements due to a newer warranty policy.

💬 Final Thoughts

This move is a precautionary one—but necessary. Reducing voltage protects users from rare but severe thermal events. However, this does come at the cost of reduced battery endurance and slower charging.

If you're a Pixel 6a owner and heavily rely on all-day battery, you may want to consider:

• Getting the battery swapped early at an official center
• Using slower (e.g., 5W–10W) chargers to reduce heat generation
• Monitoring for Android 16 system alerts in July
