, as well as the optimized power draw in standby mode result in excellent battery life. Our own battery benchmark returned over 9 hours of screen-on time when testing, which puts it towards the top of the pile, and everyday observations confirm that you can eke out day and a half or even two days of battery with it with normal usage.
Those of you who got Samsung's latest and greatest phablet will be delighted to know that an over-the-air update is rolling out that aims to improve battery life even further through some software optimizations. Besides the battery life improvements, Samsung also mentions call quality and security enhancements that will come with the 144MB update, though it's not specified what these entail.
