NTT DOCOMO has officially launched a new software update for the Xperia 1 VII (SO‑51F), aimed at fixing charging problems that appeared after the recent Android 16 upgrade. Many users had reported that their devices stopped charging properly, especially when using certain fast chargers, and this update is designed to resolve those issues.
The problem first surfaced after the Android 16 rollout on October 30. Some Xperia 1 VII owners noticed that their chargers, particularly USB‑PD compatible fast chargers and adapters from specific manufacturers, failed to power the device. Complaints included situations where charging did not progress at all, and restarting the phone did not help. This bug had a significant impact on daily usability, making it one of the most frustrating issues for Xperia users.
DOCOMO has now confirmed that the latest update addresses this bug. The new build number is 71.1.A.2.75A, which replaces the earlier version “71.1.A.2.75” released with Android 16. Users who still see the older build number must update to the modified version to ensure proper charging functionality.
The rollout began on November 18 and will continue until all affected devices are updated. The process is quick, taking about four minutes depending on the network environment. Updates can be performed over 5G, Xi, or Wi‑Fi connections, making it accessible for all users.
DOCOMO offers two update methods:
- Automatic update: The system will install the patch automatically between 2 a.m. and 6 a.m.
- Manual update: Users can go to Settings → System → System Update and apply the fix immediately.
Once the update is downloaded, tapping “Restart Now” on the notification screen will complete the installation. This makes it convenient for users who want to fix the issue without delay.
DOCOMO strongly recommends that Xperia 1 VII owners apply the update as soon as possible, especially if they are experiencing charging problems. Since the bug affects power supply, it has a direct impact on usability and reliability. Fixing it early ensures that devices remain stable and functional.
Looking ahead, DOCOMO and Sony are expected to continue releasing updates that improve overall quality and performance. While this patch focuses on charging, future updates may address other issues and enhance the user experience further. For now, this fix is a major step forward for Xperia 1 VII users who have been struggling since the Android 16 upgrade.
Quick Take by Sujit Ram: This update is more than just a bug fix—it restores confidence in the Xperia 1 VII after Android 16. Users should apply it early to avoid charging headaches.
