imagesSamsung Galaxy S2 was just recently updated to the 4.1.2 version on Jelly Bean and I can personally say they have pleased a whole lot of users. This update was simply becoming too annoying because everybody was asking everywhere about when it will come. Well, now it finally came and its seems to bring a lot of new features among which is the Galaxy S3 Nature UX user interface completely replacing the previous Galaxy S2 UI.But apart from all the new features that the update brings, it seems that the update also brings some issues. For example the battery on the Galaxy S2 running Android 4.1.2 is draining much faster than it would on ICS. Or at least that's what most of the users that installed the update are saying. Of course, the battery on the Galaxy S2 is not the best one out there, and if you even own the device for a year now it will definitely drain faster. But still, let's look into this battery draining too fast on the Android 4.1.2 Galaxy S2.As you know, one of the biggest issue with Samsung phones that are not a Galaxy S3 or Note 2 or similar is the battery. All the exciting features and improvements that the Android operating system is offering are too much for a simple 1600 mAh battery to  handle. So apparently the update Galaxy S2 to Android Jelly Bean is eating a lot of the battery very fast.Some advice may be given to prevent battery draining too fast, for example turning off Wi-Fi when not using it, turning off location from Settings, disabling all the pre-installed apps and Google apps that you don't use. But the truth is, the battery in the Galaxy S2 is simply not powerful enough to handle all that Jelly Bean is offering completely. You can indeed win a few extra hours of usage by disabling bloatware and different settings, but that will only take away from you the full Jelly Bean experience. For example Google Now is a very exciting feature and a lot of users enjoy using it, but it seems that it uses very much of the battery. Shutting it down would save some battery life, but it will simply take away a nice feature from you. And what's the point in wanting updates and new features if you end up disabling all of them eventually?Have you installed Jelly Bean on your Galaxy S2? How is your battery doing?
