Durable is gigantic understatement!
With full charge in 1.5h you can talk for 14h straight, play HD video for 7 hours or… put phone on stendby for 14 days (I don’t think it is possible to not use it for so long but, yeah) and all of this with 3000mAh battery!
Wow, that’s what I understand under battery usage optimalization. As for components it looks quite good as well:
