Following reports that the February security update for the Pixel 2 and Pixel 2 XL seems to be causing battery drain issues for the two Google phones, the company decided to address the issue saying the patch isn’t the cause of the issue. But it is hard to pinpoint what’s been causing the problems. There have been varying degrees of the issue affecting users differently. And it isn’t even limited to battery drain, some report that the phones are heating up, while others claim it takes them longer to charge. Some even report random Wi-Fi disconnections. These problems have been complained about enough that it gets a dedicated thread on Google’s Issue Tracking website. The company has confirmed it will privately reach out to users affected by these issues.
