iPhone DIY repair: Ultimate guide to replacing the battery in your iPhone

Everything you need to know to DIY (do-it-yourself) replacing a dead battery in your iPhone

If you've got an iPhone that's going on a few years old, you may notice that your battery doesn't hold a charge like it once did. That doesn't always have to mean you have to run out to buy a new iPhone. A replacement battery is actually not very costly and as luck may have it, it's one of the easiest DIY repairs when it comes to most iPhone models.

As long as you've got a little bit of patience, we can walk you through how to squeeze lots more life out of your iPhone with a brand new battery replacement.

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 at least 90 days.

You should always proceed with caution when buying replacement batteries. While a cheap price seems like a good deal, it may not be if it damages your iPhone. In this situation, you really do get what you pay for.

The iPhone 4S is only going on over a year old but for heavy users, that's enough to start taking a toll on your battery. If you picked up an iPhone 4S fairly close to launch, you're probably out of warranty by now. If you notice your battery deteriorating and no longer holding the charge it once did, a battery replacement for the iPhone 4S only consists of about 4 screws, one clip, a few tools, and about 15 minutes of your time.

Just watch out for that tiny grounding clip underneath the battery cable. You'll need it for reassembly and it's easy to miss. Hit the link below to check out our complete guide for replacing the battery in your iPhone 4S.
