Samsung Galaxy Note 4 Reportedly Receiving Update to Improve Battery Life

According to a report, Samsung has pushed an update out to the Galaxy Note 4, called firmware number XXU1ANJ4. It is said to be around 36MB in size, and it reportedly improves some features of the handset (unspecified), and significantly improves the battery life. For those unaware, the Galaxy Note 4 features a large 3220mAh battery.

The update should install after users open retail units on day one, and won't come pre-installed, as per Sammobile. Samsung is yet to announce the update officially.

Samsung is all set to launch the Galaxy Note 4 in India on Tuesday. The company started sending media invites last week for the launch of the "The Next Galaxy."

Earlier on Monday, an established retailer shared what appeared to be a promotional image of the Samsung Galaxy Note 4 that mentioned October 17 as the availability date in India. Notably, Samsung in the invite had not indicated a launch date or announced pre-orders for the Galaxy Note 4 in India, but the retailer's information has largely turned out to be accurate in the past.
