Unless you have a super-strong battery which can sustain a lot of energy at once, you’ll have to deal with this issue.Well, not anymore. This is where Greenify comes in handy!

You need to have an Android phone as it’s only available for Android. It identifies the most power-hungry apps and hibernates them to significantly expend the battery life of your Android Phone. You would have noticed that some apps still linger around in the background even after you are done using it. You wouldn’t need to do anything about them as ‘Greenify’ would auto-hibernate them. It makes your battery last significantly longer than it would in normal circumstances. Source – Greenify Google Play
