[AT&T LG Optimus G] Rishi.:
Battery : With stock ROM and Zero Tweaks , you'll not obtain a very good battery life. It can sustain a day , though with light to moderate usage.

When you install modded apps , and custom roms , or patches to improve battery life , then the phone can easily last two days with light use.

For me , I am using couple of tweaks , and now my phone can easily stretch up to two days on one charge.

However , once you set all the 4 cores ablaze , i.e. turn on performance mode , and start playing HD games and running intensive tasks , the battery drains quite quickly. But still is considerably okay.

So for battery life , I would say it's not on the high end but it's not that bad either. It's okay.

Camera : To be honest , the camera results are poor. Not acceptable enough from a 8mp shooter with such a powerful engine. I have had Nokia N95 , Atrix 4g , and couple of other 5-8mp shooters , but the results are pretty much the same despite this one being newer in terms of technology.

I am using some tweaked camera profile settings , and it seems to drive somewhat better results , but still not to be called anything better than acceptable.

If you are planning to use default Stock ROM camera app , then let me tell you that this one has hard time concentrating and focusing .

Display: If I were to explain this is one word , I would say - Awesome!!!!!

Yeah , this is one of those smartphones with best display technologies and color reproduction. The color reproduced are bright , natural and very realistic. The screen has excellent contrast ratios , despite being a non-amoled unit.

At low brightness the display really goes dark enough , and high brightness , the white appears very true , which I think is good.

The sunlight legibility is good , but only at highest brightness settings.

Touchscreen response is really good.

Cons : Highly reflective surface of the display , weak and prone to cracks.

Performance : This is the part of story where this beast outperformed every competitor it had in it's class. It's really fast and snappy.

Krait is known for their performance , and this one has 4 of them running at 1.5Ghz each , with a powerful Adreno 320GPU which can sufficiently drive that gorgeous 720p Display.

I never felt anything that can be called lag relating to lack of sufficient hardware. The UI is almost fluid , and beautiful.

I have played heavy games , like Asphalt 8 , ShadowGun , NFS MW , Strike Team , MC4 , etc and the performance was nothing less that fluid. Never felt a jitter in performance.

Though , the phone heats up a little bit. You can either relate that to the all front and rear glass design that traps the heat generated.It doesn't really heats up like hell , but still you can feel the temps. after playing 20-25mins of HD games.

2GB of ram is more than sufficient at present scenario. Plus the introduction of Kitkat has even lowered that demand , though I am not really sure if LG's going to deliver Kitkat to this previous flagship device.

Build Quality : Excellent but Prone to Cracks and Death by Fall due to all glass design.

Yeah , this one is one hell of a gorgeous phone if you love workmanship. This one sports gorilla glass at front and rear! Yeah it's glass at back. :( :) . It's a thing to be proud of as well as to be concerned of at the same time.

There have been reports that the glass at back is not as strong as LG says it should be. It's prone to developing cracks at random places , either by slight pressure or by heat build up.

So if you are planning to buy this phone , then please be sure not to drop it , because that is guaranteed spider art at the rear .

Or else buy a protective case , which really does it's job. Trust me , you are going to need it one day.

Other then the glass menace , the rest of the phone is excellent as far as build quality is concerned. It looks beautiful too.Slim profile and sexy looks.

Speakers : Outstanding , and loud enough for you to not miss your notifications and calls even in the loudest environments. It scores a lot more than almost all of the flagship smartphones when it comes to loudness.

However , the good thing to notice is that despite of being so loud , the clarity is outstanding. It's crystal clear and never feels like a broken pipe even at highest levels.

Network reception : it's quite effective and good. Since , LG has used rear-glass so its even better.

Can receive signals even in the darkest corners , but I have used phones with better signal reception , like Nokia and Motorola based phones.

Call quality - Call quality is very good. The microphone records , crystal clear sound , and the phone's call earpiece is very loud and clear. But at higher levels it feels a bit blown.

User Interface : Well the stock UI is really attractive , and extremely fluid. There are hell lots of bloatwares though on the At&T variant.

I have tried several ROMS , but I am still with Stock UI as I am still in love with it.

Ease of use : Well this one is a Nexus's kin. ( Nexus 4 ) , So expect a lot from it. They share a lot of similarities , and that leaves you with lots of possibilities. There was a time , when people even converted their OG into a fully blown Nexus 4 . ( You heard me right.) Though , its recommended any longer , because of risks involved and the availability of Nexus roms in heaps. ( And they are good too. Thanks to the Devs.)

The phone is easy to root , unlock and install custom roms.

The LG phones are notorious for not having huge community , but still this one being close to Nexus 4 , received better support . Yeah , there are good members here , who have lot to say.

Even if you land in trouble , there are devs who have found out a method to resurrect your phone damn easily . That Potion Of Life is known by the Name "LGNPST" . It's the potion of life for OG ,and the favorite among LGOG community. At least in my consideration it is . I am sure others will agree too.

Let me know if there's a part which I missed in my views about this phone.
