Some of you may remember i was a stones tbrow away from dumping this phone altogether, but reading more and more posts made me change my mind. First of all, let me.show you.this: Impossible. Right? No. Bull? Not a bit. Now, this was with light to moderate use and an extended battery, but I DID use 4g and wifi on and off for most of the day. The phone itself isnt as much of a battery hog, the problem comes from its faulty RADIO. (Yes i said faulty, deal with it) What i did was actually simple. Disable ALL connections to data, 3g, 4g, and wifi. The phones radio is weak, and is constantly scrambling to find signal anywhere it can. Shut off all your data if your not using it, and youll start to enjoy this phone a whole lot more. Reception still sucks at times but its a lot better as of late. Not sure why. Secondly, get the extended battery, no exceptions. I thought it was a gimmick at first but its a definite life saver. It MUST HE CALIBRATED. Period. Charge, die, charge power off, die, repeat. Do this 4-5 times. Yes 4-5, no less. I thought that was the biggest load of crap, but i tried kt in desperation and it works. There are still a ton of bugs with this phone, I'm not denying that.. but this cures a.major one until we can get an OTA with some better radio drivers. Hope this helps, and hopefully we'll see some results before jan 15th or i believe verizon wi have a lot of gnex refurbs to go around. Edit: and hopefully we can get some working autocorrect.
