I bought a used X2 for my wife after she dropped and fried her shiny new Droid Razr. She has used it for about three months with no issues. Last week that changed, the phone started shutting down whenever it went into standby mode on battery power. This does not seem to be an issue while plugged in. <long winded detailed description follows> Whether it was allowing the phone to do it itself or by pressing the power button to shut off the screen the phone will shut down and not power up. I have tried holding the volume button while attempting to turn on to no avail. I can pull the battery, reinstall, and everything boots just fine. I can keep the phone on for 20+ minutes playing a game, making a call, pretty much doing whatever and everything is fine but if it goes to standby a battery pull is required. I have done a factory reset twice (once while online with a VZW tech), tried with and without the data card installed, still no solution. It will occasionally alow me to press the power button to go to standby, then press again within 5-10 seconds to power back on. It seems if I wait more than 10 seconds the phone shuts down and requires a battery pull to restart. I have searched for an answer and some say to put the battery in Performance Mode. I did and it does not help. Some say it is a bad app installed. I have uninstalled everything I can uninstall and it still happens. There are so many posts on so many forums I have to think there is a solution out there but I cannot find it! I am running everything stock (no root), here are some particulars if it matters: Android Version: 2.3.5 Kernel Number: 220.127.116.11-00008-gc406305 Build Number: 4.5.1A-DTN-200-18 System Version: 1.3.418.MB870.Verizon.en.US Any help would be GREATLY appreciated!
