A faulty iPhone battery can cause a range of problems. If your phone isn't powering on, isn't holding a charge, if it's charging slowly, or draining fast, your phone most likely needs a new battery. Bad batteries also tend to expand like a balloon over time, and this is very bad for your phone. "Bloated" batteries can cause internal damage, lift or crack your screen, and can even produce smoke or flames. Smartphone batteries tend to last for about 1-2 years before they start to show a decline in performance. iParamedics always offers free battery testing and evaluations to make sure that your phone is operating at its full potential.
