I have a Galaxy Note 2 GT-N7100 running on Android 4.1.1 JellyBean. The 4.1.2 update has been released a while back, but I still am reluctant to upgrade. I have read over the Internet that it causes the battery to drain faster than normal. Is there any truth to this?
Yes there was Issue with Battery drain but they had solved the issue and you can go for 4.1.2 and performance is good.
