Google has long been known for periodically rolling out new versions of its Android operating system, each update bringing new features and improvements. The latest addition to the lineup is Android 16, which is set to be made available soon for all Pixel phones. However, cybersecurity insiders have revealed an intriguing piece of information: the new version of the OS might unintentionally block the fast-charging feature on smartphones, specifically due to the introduction of a security measure called “USB Protection.”
This USB Protection feature comes enabled by default in Android 16 and aims to safeguard devices against potential threats by limiting data transfers over the charging port. The feature restricts the charging port to a “charging-only” mode, blocking the usual data negotiations that are required for fast charging. In simple terms, fast charging works by the device and charger exchanging some data to communicate optimal charging parameters—something that Android 16 would prevent.
Fast Charging and How It Works
For those unfamiliar, fast charging has become a standard feature across many modern smartphones. As consumers demand quicker ways to power up their devices, manufacturers have answered with fast-charging technologies that push more power through the USB port. These include technologies that range from 18W to 120W charging speeds, depending on the manufacturer.
Popular phone brands have equipped their devices with advanced charging capabilities, including:
i.) Samsung offers 25W charging on its latest Galaxy series.
ii.)Â Motorola features up to 33W charging in its Moto series.
iii) Chinese brands like Xiaomi, Oppo, OnePlus, and RealMe have pushed the limits even further with 120W charging, capable of fully charging a large 7000mAh battery in as little as 45 minutes—a significant improvement compared to the 3+ hours required by traditional chargers from other brands.
These fast-charging speeds have revolutionized how we charge our devices, making it easier to power up a phone in a short amount of time, which is especially useful for busy, on-the-go lifestyles.
The New ‘Advanced Protection’ Feature in Android 16
However, with the release of Android 16, Google has taken a more cautious approach toward protecting users’ sensitive data. The Advanced Protection feature is being introduced to prevent unauthorized access to devices through their USB ports. As part of this initiative, fast-charging functionality will be automatically disabled by default.
What does this mean for users? Essentially, the phone will no longer negotiate data transfer when connected to a charger, preventing the fast-charging feature from working. While this may seem like a minor inconvenience, it is important to note that this measure is being implemented to safeguard users from potential data breaches and security vulnerabilities that could arise from malicious USB connections.
How to Restore Fast Charging
For users who still want the fast-charging feature, there is a simple workaround. To re-enable fast charging, users will need to unlock their phone and then reconnect the USB charger. This process essentially triggers the necessary data negotiation and restores the device’s ability to charge at a faster rate.
While it may not be an ideal solution for everyone, the process only takes a few seconds and ensures that the phone remains protected from potential threats.
Does This Apply to Other Devices?
It remains unclear whether Android 16’s Advanced Protection will affect devices from other manufacturers in the same way. Notably, in tests conducted on the Pixel 8 Pro, the device was able to fast-charge without any issues, even before unlocking. However, this doesn’t necessarily mean that the fast-charging feature will remain unrestricted on future devices.
Given that Google often prioritizes its Pixel lineup for updates, it is likely that the Advanced Protection feature will first roll out to Pixel users. Pixel devices are often the first to receive new features, patches, and updates, meaning Pixel owners could experience these changes sooner than users of phones from other manufacturers.
Conclusion
In summary, the upcoming release of Android 16 introduces an exciting new Advanced Protection feature aimed at securing devices against threats via USB ports. However, this security measure may inadvertently block fast charging by default. While this change is being made to enhance user safety, the workaround of unlocking your phone and reconnecting the charger should allow users to continue enjoying the convenience of fast charging. As Android 16 rolls out, it will be interesting to see how other manufacturers respond to similar security concerns and whether they adopt similar features in their own software updates.
