Samsung is preparing to launch the Galaxy S6 at the Mobile World Congress on March 1, and everyone is scouring for news on what could be the biggest tech announcement of the year.

One feature that could be returning to the Galaxy line is wireless charging, originally available on the Galaxy S4 but removed on the Galaxy S5.

Even though wireless charging isn't a game changer, Samsung might be adding new technology for faster charging to make up for a limited 2550 mAh battery.

This might be the first time Samsung locks its battery inside of the device, not offering a detachable back to remove the battery. This means Samsung will need new ways to provide extra life on the Galaxy S6.

Samsung will use the Qi standard for wireless charging and should launch its own charging pad for the Galaxy S6. It may also offer ways to save battery life, like a low-energy mode.

Stripping back the TouchWiz skin may also lead to extra battery life due to Samsung's overuse of animations on its Nature UI. Hopefully, on the Galaxy S6 most of these battery draining animations will be removed in favor of Google's new Lollipop animations.

The Galaxy S6 will run on Samsung's octa-core Exynos processor not known for its battery saving capabilities. The Qualcomm Snapdragon 810 does have several features to save battery, but Samsung had issues installing it on the Galaxy S6.

Samsung might also be adding a 2K display onto the Galaxy S6, another source of concern when it comes to battery life. Hopefully, Samsung will learn from LG's own troubles with the G3 battery life.
