My battery is draining really fast and takes a long time to charge
Quick story that may help some other people:
I bought my Verizon Galaxy Nexus used on Craigslist. It was a good deal. Right away I bought the extended OEM battery as well as the Seidio extended battery. The first thing I noticed was that battery drain was unusually fast. I'm no noob to Android phones, and a few of my prior phones had bad reps for battery life (HTC Incredible, Samsung Nexus S, HTC Thunderbolt), but this was something special. For the first time in my life I felt the need to use Juice Defender, and that was only marginally helpful.
I never minded with the other phones because I would use the largest battery available, charge on my 40 min commute to work, charge on the commute home, and everything would be fine. The problem with the Galaxy Nexus is that not only would it drain fast. It would take unusually long to charge, espcially when using during a charge.
The next thing I noticed was that the phone was getting very hot, especially in the top left corner, even when it wasn't doing much. Turning off LTE seemed to help but not much. After a couple months of use, trying ROM after ROM, kernel after kernel, reverting to stock, etc, things took a turn for the worse. I would go to sleep with a pretty good charge and wake up the next morning with a dead battery. Sometimes the battery was so dead it wouldn't even take a charge.
I called Samsung, and they were very responsive. Even though I wasn't the original owner and had no proof of purchase, they paid shipping both ways and had my phone repaired and back in my hands within a week. The paperwork that came with the repaired phone just said that a "component" had been "replaced". I called and asked them which component was replaced, but they couldn't give me any more details than that.
My repaired phone gets warm sometimes, even very warm, but I haven't noticed that hot upper left corner. Meanwhile, the battery life is night and day better than it has ever been. I can get through the day fine with the Samsung OEM extended battery, and the Seidio lasts damn long like it should but never did. The batteries now charge much faster as well. I can finally enjoy this phone like it's supposed to be enjoyed, and I have no more thoughts about upgrading some time soon.
Maybe Samsung just has amazing customer service, but the speed with which they handled this as a warranty repair makes me wonder if this is a known issue on their end. In Googling for a solution to my problems, I came across other reports of people who found their battery suddenly dead, unable to take a charge.
Here's my advice: If your battery life is atrocious - and I mean atrocious even with the screen pretty dim, no accounts syncing, LTE disabled, factory stock with no apps installed...
and you find your Galaxy Nexus taking a long time to charge (using the OEM charging cable)...
and your G-Nex gets super hot in the upper left corner even when it isn't doing anything...
then try sending it in for a warranty repair. The phone I bought on Craigslist was defective, and after struggling with it for months, all it took was a one week repair and I'm 100% content. It's a completely different phone.
