TL;DR
- Android on the Google Pixel 9 sequence has a better threshold for what it considers quick charging.
- Earlier Pixel telephones would present the “charging quickly” textual content on the lock display for any charger that delivered no less than 7.5W of energy.
- The Pixel 9, nevertheless, solely exhibits this textual content for chargers that ship no less than 20W of energy.
It’s been over two weeks since Google unveiled the Google Pixel 9 sequence, and we’re nonetheless studying new issues concerning the units that the corporate didn’t point out at its Made by Google occasion. Whereas it’s unlucky it didn’t get round to mentioning neat options like Adaptive Contact, it’s comprehensible that it didn’t have time to say a few of the actually minor quality-of-life adjustments. That’s what we’re right here for, although.
Earlier right this moment, APKMirror founder Artem Russakovskii posted on X about a side of his Pixel 9 Professional XL that he discovered annoying. He talked about that his Pixel 9 Professional XL now not exhibits the “charging quickly” textual content on the lock display. As a substitute, the lock display exhibits an ETA for when his cellphone will full charging. The explanation that is annoying is as a result of it makes it tougher to inform if the cellphone is linked to a quick charger.
Additionally the Pixel 9 Professional XL annoyingly eliminated the “Charging quickly” and changed it with an ETA. Whereas the ETA is helpful, I can now not simply inform if I’m linked to a “quick” charger or not.
Because it seems, although, the “charging quickly” textual content hasn’t disappeared from the lock display. It nonetheless exhibits up for those who use the Google 45W USB-C Charger, as talked about by some customers within the replies to Artem’s publish. Nonetheless, you don’t want a 45W charger for the Google Pixel 9 to make the “charging quickly” textual content seem on the lock display, and also you actually don’t want to make use of Google’s official charger to make it seem, both.
In actual fact, any charger that may ship no less than 20W of energy to the Pixel 9 will set off the “charging quickly” textual content to seem on the lock display. That is because of a current change in Android that’s presently solely enabled on the Pixel 9 sequence.
We reported earlier this 12 months that Android was making ready to improve the quick charging threshold from 7.5W to 20W. The OS on all different Pixel telephones nonetheless makes use of the previous quick charging threshold of seven.5W, however the OS on the Pixel 9 sequence makes use of the upper 20W threshold as a result of Google set the system property charging_string.apply_v2 to true. When this technique property is about to true, the 20W quick charging threshold is used to find out whether or not to indicate the “charging quickly” textual content on the lock display. Though my preliminary reporting on this modification was based mostly on code I discovered inside the third beta of Android 15, I examined the Android 14 firmware for the Pixel 9 sequence and located it was enabled there, too.
Although the quickest charging speeds are solely assured for those who use Google’s official 45W charger, you must be capable to quickly cost any cellphone within the Pixel 9 sequence utilizing a quick USB-PD PPS charger, as Google’s telephones don’t use a proprietary wired charging normal. Nonetheless, it’ll must ship no less than 20W of energy for the Pixel 9 to think about it as “quick,” because the Android OS on the system now not makes use of the previous, outdated quick charging threshold.
