    • Li-ion iPhone battery

      The Overstock price is great but -this battery was totally defective. Overstock gave me a refund ASAP (but no reimbursement for S&H). Excellent customer service.

    • Worked fine at First

      I have a iPhone 3G , So I bought this low cost battery and the install was very easy. You need more tools than what was given to do the install. I used a paper clip to take out the sim card, a 00 screwdriver for the tiny screws , a suction cup to lift up the screen. So this battery worked fine at first then my phone keep shutting of automatically stuck when it was on and , I took the phone apart again took out the battery then put it back in and still had the issue I then reinstalled my old battery and the problem went away, maybe I got a bad battery.
