Default How to tell if battery is defective?

I am within the return period of my G2, but not sure if my battery life is normal or not? I get 3-4 hours screen time on VZW 4G, with sync on and all GPS and NFC related stuff off, running a de-bloated LG rom. All the reviews I have read they getting 6-8 hours of screen time, pretty much twice of what I am getting. Is this normal or do I have a defective devices? I kind of don't want to return as I have a screen protector I got at the same time I got the G2 and hat the store install so that makes transferring the protector harder? If it really is defected, then I must return it, but how can one tell if battery is really defective or actually normal?

On a side note I know people with Galaxy S4 getting similar battery life as me, but I would think that would be expected since the S4 has a smaller battery vs the G2. Thanks.

Depends on many things and mainly what brightness level u get the screen time u mentioned for. It is normal to get way less screen time with 100% brightness than say with 50% or less brightness. Also u don't mention where u get the said screen time. Is it browsing the net or watching youtube vids for example or playing heavy 3d games? That affects screen time as well. Way too little info u shared here for anyone to be able to really help you...
Hit the thanks button if I helped you...

Try disabling sync, Google now, and have it on 50% auto brightness...it has helped me a lot.

The OP has a point. I have seen that the Android System takes almost the half of the battery stamina. And after tracking what exactly it came up that the Radio drains to much battery. I try to find solution or anything but didn't find anything yet.....


Maybe Levi Strauss should sue Apple too. He came up with the single button concept on pants first. Apple copied him...........

HTC - was great
Moto - is good'ish
LG G2- the best phone i had (for now)

How did you figure out it's the radio, bro? I also have a massive android system drain and I don't know what it is.

I used wakelock detector. The app showed me that the most power is gone to the radio.

I can't understand a sh*t. Everything was fine and suddenly it starts to consume power like hell. I disabled play services and all apps except play store. Removed unused apps even those from LG like dictionary etc. Now i am at 87% with 1hr 14min screen time and android system is still with biggest rate of power consume. At least android os is no more second power consumer....... i am goin nuts right now....

Even my SXL after all updates with everything on has less power drain then the G2...and the most consume comes from the screen.

I disabled knock on and I am at 85% with 1h 8 min sot. Android OS is the second highest drain but android system has settled down a bit.
