If you still haven’t gotten the battery replaced in your older iPhone, the price to do so by Apple has gone back up. However, if you’re intrigued about doing it yourself, iFixit is still discounting its battery replacement kits at $30.
If you’re out of the loop, it was discovered a little over a year ago that Apple was purposely throttling down iPhones with old, degraded batteries to prevent random shutdowns and other problems. The fix? Replace the battery. But Apple didn’t tell anyone that until they were caught red-handed.
At that point, Apple began offering discounted battery replacements, which also led to increased wait times at Apple Stores. iFixit stepped in and discounted its battery replacement kits so that if you didn’t want to wait on Apple, you could do it yourself instead. And while it may seem daunting, it’s actually not too bad of a process.
If you’re not sure if your iPhone could use a battery replacement in the first place, you can check the battery health by going to Settings > Battery > Battery Health. From there, it’ll tell you whether or not you could benefit from a replacement.
