i would give it an 8 to a 9 i actually really like it but unfortunately the battery life on it is leading me to go exchange it for something else. I will admit i am a heavy user, just to give an example today i unplugged to day at 6 am went to the gym had pandora for about an hour, came home and youtubed, fb'd, a few txt, few phone calls at around 11:30 i plugged in and was about 75% so i plugged in, took a shower, got ready for work. unplugged and i was about 90% got to work and much of the same fb'd, googled, youtubed, txt and a few calls. at around 6 i was at 40%. And heres where the problem lies, most will say well whats wrong with that? which for most this will suffice but for me this is a big issue. at this time is where i start receiving more calls more txt, i want to see whats going on as far as f.b. and other such things. So this is decision time do continue, knowing i will mostly likely be in the teens by 8 (time that i get off work) then if something happens as far as getting together with friends to meet up at a bar then im screwed. i wouldnt have enough juice to capture moments and the must have fb pics of your drinks and food(lol) or just receive a call or anything. Alternative would be start to recharge at 6 and not be able to toy with it till 8 and possibly be at high 60's low 70's. And before you guys say it, yes i can plug in while at work and yes i can get a car charger but as most of us know if you use it while charging it either stays at the same percent or crawls a few points up, and charging in the car amounts to a few percentages up given the short drive.
So having said all that, the phone is gorgeous, performs great, boom sound makes youtube, games, videos a great expierence,the screen is beautiful. But for me i have almost fully made up my mind to return it. Had i had the option for an extended battery i would keep it no question. Also because i just remembered just to give you a better gauge of how heavy i use my phone, my last phone was a s3 with a 4000mah battery and i would run it out by the end of the night but i never feared running out of juice getting off of work. And i mention this because i know for most this phone does a bit better or at least the same as most phones in the battery department but regretfully not for me.
yes i do tend to ramble. hope this helps.
