Numerous Sony Xperia users have recently reported that they are witnessing an astronomically high amount of battery drain over the past few weeks. Upon further digging into the complaints, we found out that most of these issues first came to light right after users installed the January Google Play System update [it’s a Project Mainline update and is different from OS/security patch update].
Moreover, upon having a look at the battery chart, we found that it was a system app that was consuming most of the system resources. The name of the app is CrashMonitor which is used to debug every instance of a system crash and collect data pertaining to the same. But ironically, it is the one that is resulting in the excessive battery drain on Sony Xperia devices. So you’ll have to disable this app via ADB, which, in turn, should rectify the underlying issue as well.

STEP 1: Install Android SDK
First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one.

STEP 3: Establish ADB Shell Connection
STEP 4: Disable Xperia Crash Monitor
That’s it. These were the steps to fix the Sony Xperia battery drain issue after installing the January update. As far as the official stance on this matter is concerned, the developers are yet to acknowledge this issue, let alone give out any ETA for the rollout of a fix. As and when any of these two things happen, we will update this guide accordingly. In the meantime, the aforementioned workarounds are your best bet.
