Sony is taking longer than expected in rolling out Android 6.0 Marshmallow update to its devices, but that doesn't mean it has sidelined it all together. In fact, the Japanese technology giant has started seeding the Marshmallow beta with a new feature called 'soft charging' to the Sony Xperia Z2, Xperia Z3, and Xperia Z3 Compact, giving a hint that the firmware update will come to the devices soon.

After getting the firmware beta update, users of the device will receive "Charging optimization is enabled" message when they first charge their phone. The feature can be disabled by going to Settings > About phone > Status > Charging optimization.
