The Samsung Galaxy S III packs in a powerful Exynos 4412 quad-core Exynos SoC clocked at 1.4GHz, that makes sure things remains smooth even under heavy load. Even though Samsung packs in a beefy 2100mAh battery inside the Galaxy S III, and some smart power-saving features, the handset’s battery life can be found lacking in certain situation.
A script from an XDA user, however, should help Galaxy S3 owners in extending the battery life of their handset. The script automatically turns off three out of the four cores of the Galaxy S III when the phone’s screen is turned off, thus preserving battery. The script, in fact, works with any dual-core or quad-core sporting Android device that has root access.
There is quite a debate going on over at the XDA forum thread whether this script actually makes any difference or not. While some users have reported a visible improvement in battery life, another developer has some solid proof that the script does nothing to improve battery life.
If you own a Galaxy S III with root access, and are looking to increase the battery life of the handset, go ahead and give the script a try.
