Just recently a leaked firmware XXELK4 containing the latest Android 4.1.2 for Galaxy S3 was released on the internet world. Probably thousands of Galaxy S3 users installed it immediately as it seems to be very close to perfect, even though this is not the original update and you have to install it via Odin.

A great thing about this update to Android 4.1.2 is that it brings amazing battery life on your Galaxy S3. In the past people reported that the Jelly Bean update is terrible with battery performance.
Well, it seems that battery problems are gone now with this leak. There have been a lot of users stating they get double the screen-on time they got on Android 4.1.1. Also the battery now lasts even one full day with data on and wi-fi on. Of course, there are some tricks you can try to make sure that you get the maximum of your battery. But overall, the battery performance is great with the Android 4.1.2 update.
Here are some testimonials from xda-developers forum users that installed this firmware:
- “Finally a firmware that’s excellent for battery”
- “Battery is awesome on lk4 :)”
- “This new leak is great, smooth and battery friendly, no more wi-fi battery hogging.”
If you are the kind of user that knows what Odin is, I recommend you try this leaked firmware if you are the owner of a Galaxy S3 device. Even though there may be some bugs and your warranty is voided once you install it (probably you already voided it), this update brings amazing new features for the Galaxy S3. Of course, you can always wait for the OTA that is supposed to roll in December, but look how much it took for Android 4.1.1 to roll on all Galaxy S3 devices, maybe waiting isn’t a solution anymore.
