Does the nfc option kill battery life - Samsung Galaxy Nexus

I had it on this whole time wondering if that was killing the battery life all this time

It's only active while your screen is on. So it shouldn't affect your battery life that noticeably.

[Q] Good battery life?

Hi
Right now i have jelly belly with franco kernel build 17. But i get like 8hours of battery. Under clock to 700Mgz, undervolt, low brightes, and no data. So any help with this will be apreciated.
Ps: i use a battery saving app DX-Battery saver

Download CPU spy... and see if the phone is sleeping properly

It is. I only text in it. Most of the time its on deep sleep

Probably have a wakelock issue. And underclocking that far can actually cost you more battery because your phone stays awake so long completing tasks rather than sleeping.
Also, battery saver apps suck.
My friend told me that so i went to 1.5

Battery improved after jelly bean!

Ok when I had 4.0.4, my battery life was terrible and that was because of battery leak from android os. Now , android os is taking battery normally anyone else noticed this?

Mine is not too bad. 78% after about 8 hours of usage, standby. I'm at work, so barely used the phone today.
Ah my battery life increased too. Glad to see Google fixing some problems ICS had.

That's pretty standard. There's a lot of battery life threads where you can post your stats.

That's pretty good. Mine gets around the same - I always forget to check it before charging. XD

I used to always get 2hrs. Im not longer using light flow now and I think that could have been one of, if not all, the culprit to being plateaued out at 2hrs.

Show me a 5 hour screen life with real usage and I will be impressed.

Well my battery dies really fast after I updated. I have the stock battery.
