With Android 12, the Google Pixels will charge more slowly at night to conserve battery
Android 12 does good for your battery. Some Beta 4 users have noticed that when they charge their Google Pixel overnight, it gets to 100% just a few minutes before they wake up. This feature, already existing for a few months, seems to have been improved by the Mountain View firm.
At the end of 2020, Google introduced a new feature for its Pixels. Called “Adaptive Charge”, this blocks the charging of smartphones at 80% to protect battery life. It is activated in particular at night, to avoid spending too much time receiving the maximum amount of energy. Despite everything, the user still benefits from his battery at 100% the next day, thanks to an artificial intelligence that slows down the recharge to finish it a few minutes before waking up.
Only available on the Pixel 3, Pixel 4, and Pixel 5, Google has been relatively quiet on this feature. And for good reason : it does not work exactly as expected. Firstly, because it requires the establishment of very specific conditions, such as the fact of start charging after 9 p.m. and set an alarm between 5 a.m. and 10 a.m.. Secondly, because she still needed small optimizations. According to users of the latest beta of Android 12, it is now done.
Google improves Adaptive Charge for Android 12
Concretely, Charge Adaptive works the same way as before. In contrast, recharging is much slower past 80%. According to members of Reddit, their Pixel hit 100% battery between 30 and 90 minutes before they woke up, much better results than they got just a few weeks ago.

“In Android 12, the settings allow us to see the battery usage during the previous 24 hours, including charging sessions”, explains one of them. “So I was able to notice this: up to 80% the Pixel charges quickly (like in Android 11) despite having adaptive charging enabled and then, like in Android 11, it slows down until your awakening. However, it goes much slower: it finishes charging just half an hour before the time you are supposed to wake up ”.
Another specifies that “It charges up to 80% quickly and then stays on standby until about 3.5 hours before you wake up. Then it recharges for about 90 minutes at 6% per hour (so about until it hits 90%), then recharges for about 30 minutes at about 25% per hour until it is fully charged, which ends approximately 90 minutes before you wake up ”.
