Firmware update kills bug draining Apple AirPods Max battery

The Apple AirPods Max is an over-ear headphone that turns on automatically when it detects that they are over the user’s ears. Each ear cushion uses memory foam to create a seal that Apple calls an important factor in creating immersive sound. The AirPods Max also borrows the Digital Crown from the Apple Watch to allow for precise volume control, to activate Siri, play or pause music tracks, and answer or end phone calls.

This past Tuesday Apple released firmware version 3C39 for the AirPods Max. Since Apple did not include any release notes with the update, many were forced to blow the dust off of their Magic 8 Ball to find out what good the update did for their AirPods Max. Some believe that the update exterminated a bug that causes the battery to drain rapidly whenever the device is placed in its Smart Case.

When the AirPods Max is placed in their Smart Case, they are supposed to go immediately into “low power mode” followed18 hours later by moving into “ultra-low-power mode.” But since the wearable was released in December, some users have complained that the battery life on their AirPods Max drops from 100% to 1%-or even down to 0%-overnight even when the device was sitting in the Smart Case all night. A pair of graphs depicting battery usage on the AirPods Max prior to and then after the update to 3C39 reveals that before the update, the AirPods Max battery was draining every 30-minutes. The graph covering the battery drain following the update showed a very little drop in battery life for the over-ear headphone every half-an-hour.

The reason for the improvement can be traced back to one big adjustment. Prior to the update, with the AirPods Max in their Smart Case, it would take 18 hours for the “ultra-low-power mode” to kick in. However, after installing the firmware update, it takes only 30-minutes for the “ultra-low power mode” to start working. That means that the battery stops draining too fast 17 and a half hours earlier than before. The update also exterminates a bug that causes the AirPods Max to crash when connected to a device running iOS 14.5.

So how can you install the firmware update on your AirPods Max. What would you say if we told you that it is not possible to do it manually? The headphones update automatically when connected to a power source while located right near your iPhone.
