I have a 4s and have had fair battery life. About 6-7 hours usage and couple days of standby. My problem is that I have springboard crashes. I've had crashes in launching the appstore and settings apps and some appstore apps. I have quite a few "LatestCrash" reports and a few LowMemory ones. I have done a dfu restore 2 nights ago so not sure what to do? Should I get it replaced with the error codes that I've been getting?
