Warning about battery replacements

When replacing a battery in your iPhone, or any electronic device for that matter, it's very important you use high quality or OEM batteries. While using aftermarket components may not be unsafe in some circumstances, a battery is a huge exception. We recommend only using reputable suppliers for battery replacements like eTech Parts, who provide not only high quality replacement parts but will warranty them against defects for up to 6 months.

Even though the iPhone 5 features a much larger battery than previous models, it's also powering the pixels to a larger screen. Since the iPhone 5 is now more than a year old, many owners may be seeing shorter than expected charge cycles that could warrant a replacement. Unfortunately, the iPhone 5 also seems to be more susceptible to faulty batteries. The most common issue seems to be users reporting when their iPhone 5 falls below 20% or so, it turns off and won't turn back on until plugged into a charger. This issue however, shouldn't be confused with a burnt out IC chip due to using a faulty charger. But if you're sure your battery is just bad, we can walk you through each and every step of replacing it, along with links on where to buy a new one.

The iPhone 3G and iPhone 3GS are well past showing their age but that doesn't make them disposable phones for many folks, at least not yet.

Perhaps you use it as a standby phone or iPod or you'd like to give it to a friend, relative, or child. Regardless the reason, a battery replacement can bring new life to both the iPhone 3G and iPhone 3GS. While a replacement involves quite a few more screws than other iPhone models, it's certainly doable for anyone mildly skilled with DIY repair. If you're willing to take the time and have just a few ninja moves up your sleeve, it's a super cheap repair to perform and may be worth it simply to have a spare phone laying around.
