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.
Not comfortable with DIY repair? Leave it to the pros
If you aren’t comfortable performing a DIY repair on your own, don’t. It is possible to cause more damage or run into issues you aren’t ready for. In this case, it’s probably better to either pay the money for a replacement device from Apple or use a local or mail-in service that will handle the repair and any issues that may arise for you.

Pod Drop locations and mail-in options 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.
