    My iPhone doesn't drain to 0% anymore before it turns off, it drains to 4% (always) and then turns off. If I plug it, it turns on after a few seconds. At the beginning it always took a few minutes until it turn back on, so I'm wondering why it does that now and if I can fix it?

    Does anyone have the same problem?

    My original iPhone (2007 model) used to die before it even gave the 20% warning. Haven't noticed any issue with my iPhone 4 or 4S turning off with less than a few percent left, but they don't usually die on me either.
    Maybe your battery meter needs to be calibrated better? Do you charge it to 100% uninterrupted occasionally after letting it drain?

    This happened to me & I turned it back on & it drained from 4 down to 0 and then I calibrated it & that seemed to solve the issue.

    Yes, I usually charge it to 100%.

    I will try that the next time!
