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.
