Recently I got a security update and I installed it. From the next day I'm facing a serious battery drain issue. Earlier my battery would last for a whole day for minimum 6 hrs on a full charge. But now after the security update, usage of 2 hours battery percentage comes down to 30 and below it. Above are the screenshots provided from which you can see that I barely used any app and still the battery percentage gone to 19%. Please help me regarding this.
