  • didn't seem to work with my iPhone 3GS (32GB)
    Verified Purchase

    I swapped my original battery with this one, expecting to get longer battery life. My phone kept crashing re-booting randomly, and I also discovered that my iPhone would not charge. To double-check I swapped back to my original battery and everything was working fine. So I am staying with my old battery as of this review. I could not tell if the battery is defective, or if there is an issue with compatibility with this battery and the iPhone 3GS based on my experience. Therefore I would not recommend this product to someone if they have an iPhone 3GS.

  • Not Compatible 3gs
    Verified Purchase

    Listing said this battery was compatible with a 3gs 16gig iphone. I installed this battery and induced the iphone to reboot every 5 minutes. After connecting to itunes, an error code kept appearing. The error codes translation was "bad battery/wrong battery". the battery i was sent was a APN 616-0347 3.7v(covered by another sticker). The battery required for a 3gs 16/32 is a APN 616-0435 4.51whr. Not worth the time and effort to send back. Just fix the listing. Thanks. 1 star for the quick shipping.

  • Cheap product=Low performance
    Verified Purchase

    I selected the product based on the low price but I will never do it again.... Installation was a bit difficult but there are few good internet sites with clear instructions. The battery was charging and performing good for the first five days, necessitating a recharge after 24-30 hours, after that, if we were using the phone or just leaving it open or closed, the battery was loosing the charge in less than 7-8 hours. I suppose that this OEM product is made with the poorest and cheapest Chinese Li cells. It is not worth even returning it. I will shop around for a new phone with available replacement batteries on the market...

  • replacement battery caused frequent phone restart
    Verified Purchase

    Mechanically correct - it fit in the iPhone 3G. Replacement battery caused iPhone 3G to restart frequently, so I put the original battery back in and the problem was eliminated. For that price, I will recycle it instead of paying return shipping. Paid 2x battery cost for faster shipping, so that is extremely annoying.

  • Battery ok once the bugs ironed out
    Verified Purchase

    Installed the replacement battery in my 3G. Firmware 3.1.3. Followed instructions on youtube. Took about 35 minutes, being careful. I purchased the suction cup and screwdriver set as well from overstock. Only needed the phillips screwdriver and the suction cup from the purchase. The battery, once installed, only lasted about 9 hours (no different than my original that was 3 years old). I then synched the phone (but not updating the OS - keeping it at 3.1.3) and now the battery has lasted around 24 hours with light use - still with 70% power left. I am not sure why the synching made the battery last longer, but it appears that it did. I will update if the battery meter is not accurate, but so far it looks good. Good luck!

  • its a friggin battery for the 3g
    Verified Purchase

    replaced a battery in the iphone 3g with this one. Seems to work great and possibly better life than the original battery. Just followed the instructions on youtube and it was all good. I would recommend a suction cup to get the screen off after removing the first 2 screws on the iphone. peace out ninjas
