My 3GS iPhone randomly shuts off
My 3GS iPhone randomly shuts off or gives a low battery indicator even when the battery is not low. I tried going to the Apple store and they were not helpful saying to close out apps using the multi-task button. Even after doing that, my phone was continuing to shut down. First is was around 33%, then 54%, then 76%, then even at 97%. So I had the battery replaced with a brand-new battery.
Now not only does the phone randomly shut down saying a low battery, but it is not recognizing the charge on the battery. I had the phone on for six hours unplugged and it remained at 100% charge. Then I went to make a phone call on it and after two minutes the phone completely shut off. It would not accept a charge. I had it charge overnight. I tried using different cords. I tried plugging it into a USB port on a computer, using the wall charger, and a car charger. The phone kept saying the battery was dead. Then miraculously then phone started to work a day and a half later, but only for one phone call. Then phone died again and has not accepted a charge for two days now. You would think after two days, the NEW battery would be charged.
My phone is not under warranty. I do not have the funds to purchase a new iPhone at this time.I know there have been a lot of posts about this, but I have tried every concievable option out there and nothing is working. I'm frustrated. Is this an operating system error and can it be fixed? Or is the phone trashed? ARGH!!
