Ok, as if the LTE doing just 300 kb/s wasn't bad enough, around day 10 or 12.. Verizon pulled those same old scam artist tricks out of their sleeves. With no warning, without any high usage (honestly... it was too slow to use and enjoy it), my phone constantly went to 3G, and stayed on 3G no matter WHERE I was. I could go into airplane mode and turn it back off, and it would connect back with LTE. If I constantly used LTE, it wouldn't drop the LTE... but as soon as my phone wasn't being used for 15-20 seconds... yes, literally that amount of time... back to 3G. That... is how a scam artist does. OH, and not only that, but if you are ever in east Tennessee, you can put my word to the test. Verizon 3G is UNUSABLE. 10 kb/s all the time, and it's been that way for 8 years. In AT LEAST a 60 mile radius. They get you right up there to the 14 day WalMart electronics return policy, then they flip the switch. JK, it's automatic because it's programmed, but you know what I mean.
I have gotten many of the free apps from Amazon, but have few of them installed. I wish I could remove the ones I don't care about from my list! At any rate, I had an epiphany after reading this thread. One of my other major annoyances is that the notification bar almost always said I have new apps to install and/or updates. During this most recent burnout of battery, I went into the App Store app and disabled ALL notifications. The CPU usage abruptly stopped and my phone went back to normal. I wonder if the app store is waking up and comparing the list of apps you have with the list you own (since my list is rather extensive, even though I only have a handful on my phone), and this process is what's burning up the CPU and thus the battery. I'll keep an eye on it and see if that actually fixed it permanently!
