iPhone 3GS Batteries

Our iPhone screens go through multiple layers of inspection and testing to ensure you receive the highest quality screen available on the market. Our suppliers perform full functional testing on all iPhone screens they receive from the factory, and reject any parts that fail to meet our rigorous quality standards. Supplier testing is routinely audited by iFixit staff in China to guarantee that they are doing it right. iPhone screens then undergo additional inspection once they are received by iFixit, with our team performing functional testing and measurements of luminance and color balance. Display assemblies that fail to meet our specifications never reach our shelves, enabling us to stand behind our iPhone screens with a lifetime warranty.

Our iPhone batteries are sourced directly from the factory, and iFixit staff routinely audit testing procedures and assembly processes to ensure our batteries are of the highest quality. Our suppliers have been carefully vetted to guarantee that they can meet our rigorous quality standards. We closely monitor quality metrics to confirm that our batteries are meeting the quality and performance expectations of our customers, and we stand behind all of our batteries with a one year warranty.

Your repair experience is not going to be easy or enjoyable if you receive a part that doesn’t work. To save you the frustration, we ensure that our products are fully tested. We routinely audit the testing procedures of our suppliers, and closely monitor quality metrics to verify that they’re doing it right. If we identify an issue, we implement our own internal testing to prevent faulty products from reaching our shelves. If a part fails to meet our meticulous quality standards, our team will intercept and reject it — so you can buy with confidence. Our batteries carry a one year warranty, while our other parts are backed by a lifetime guarantee.
