having major issues with my iphone 4

[TheKidHypno]

i've had it for a little over a year. i took it to the local ubreakifix store and they had no answers.

1. battery life is terrible. i can't get 6 hours out of this thing even with minimal use. it loses about 15% battery life without even using it per hour.

2. won't connected to my computer with the same cord that charges it with no problem

3. when it's in sleep mode the lockscreen flashes every minute (sometimes it will even bring up the play button for ipod as if i were to double click the home button)

4. it will go straight from around 40% to 1% then die.

what's wrong with this thing??
