Good battery life, especially the web browsing rating is great! This is it(unless Xperia Z1 beats it, which I doubt).
Finally, LG has put huge efforts to make the Optimus UI a worthy rival of Samsung's TouchWiz. And you know what - this time LG might have done exactly that. The new Optimus UI is more coherent and more functional, bringing lots of useful features and services while still managing to stay relatively simple to use. We have always appreciated the many themes and icon packs LG was offering with previous handsets, but let's be honest - nobody above the age of 12 was actually going to use some of those colorful disasters.
LG has done some great work on the design and ergonomics too, introducing the innovative Lock/Volume key on the back. Its positioning right under the user's index finger is indeed very clever and we are sure though at first it may look odd, it is one of the LG G2 key selling features. And we really like the double-tap lock/unlock trick too.
Please for the love of god stop listing NON removable battery as the main disadvantage.With new crop of devices one could easily get 2 days of battery life especially with 800.It's not 2010 anymore.
