this has been going on too long wtf is this? just recently it did the worst yet.. -leave house, battery 42% -walking outside check time, battery 42% -10 mins later check for messages, battery 31%, phone shutsdown as it would with 1% battery, will not start again just shows plug into power screen until it "warms up", it was 10c outside not -40,with my hand in pocket holding the phone as always.. -soon as i get in the mall it started booting up the stopped and shutdown again MID BOOT.. -10 mins later boot up fully, battery 34%, shutsdown again in 1 minute -10 mins later booted again, stayed on now the battery is 36% -updating 2 apps over lte, battery shoots from 36% -> 20%, shuts down seconds after apps finished updating -boots up again (boots fine when its "warm" room temp warm), battery 25% -hour later it shutsdown again, countless reboot tries (outside again) it finally boots, battery 10%, shutsdown.. -get home, boots, battery 22% for the next 4 hours the same shutdown/bootup battery going up and down keeps continuing until the battery is ACTUALLY down to 1% ios 6 never ever did this, at worst it shutdown once at 4%. even using it in -15c cold winter it never did this. i always take care of my device and battery, i do the full charge/run down once or twice a month i do everything apple says on their battery faq, it has never been exposed to extreme cold or heat not even for short periods. yes i reinstalled 7.0.3(and from dfu even though its no different), yes i wiped all network settings, yes i wiped ALL settings, yes i tried turning off lte, yes i did soft/hard reboots, yes i tried wiping everything setup as new, all same result, it is not my backup. it is also out of warranty as of sept when iphone 5 launched. im certain this is a software problem thats APPARENTLY NOT GETTING BITCHED ABOUT ENOUGH TO APPLE, not hardware..is there anyone else with this problem that found a magical fix that i havent tried?
