Charging the last few percentages is taking hours on Pixel phones
With the December 2024 Feature Drop, Google introduced an option to limit charging on Pixel smartphones to 80%. When enabled, the phone charges at its normal pace until the battery reaches 80% capacity, at which point charging stops automatically. All this is done to keep the device’s battery healthy for longer.
That’s exactly how the feature is intended to perform, as per Google

While most of the affected users are certain that the slow charging is being caused by a bug in the latest Pixel update, Google disagrees. The same issue was also recently reported on the Issue Tracker. A comment under this post, which appears to be from a Google employee, says that this behavior isn’t caused by any bug. Instead, it’s exactly how the 80% charge limit feature is designed to function.
It has been further noted that “in the current software build, the device charges at normal speed until it reaches approximately 77%, at which point it transitions to a lower current to reach the final 80% limit.” However, the comment also mentions that “we (Google) are currently working on optimizing the user experience.”
Something seems fishy
Google says the latest software update reduces your Pixel’s charging speed near the limit to manage battery health. I can’t thank you enough for that, Google. But does that mean that prior to this update, the feature wasn’t actually helping maintain battery health?
All that said, the only solution you have right now is to turn off the charging optimization option, which will eventually make your phone charge to 100% instead of stopping at 80%. As aforementioned, the tech giant is said to be working on optimizing the user experience of this capability. Let’s hope that by this they mean the engineers are working to reduce the time your Pixel currently takes to juice up the last few percent of the battery with the charge limit enabled.
