True, but because there&#x27;s no &quot;warranty void if removed&quot; stickers inside, you could open up the iPhone, unplug and replug(?) the battery, and close it up. Apple wouldn&#x27;t be able to tell. Heck, I&#x27;ve replaced batteries in iPhones and they were taken into the store for other issues and they were covered under the warranty w&#x2F;o a problem.<p>So, AFAIK, there&#x27;s no warranty monitor to tell if the battery had been removed because that would almost certainly have false positives with phones that have fully depleted batteries. Sure, if you replace the pentalobular screws with the Phillips from iFixIt, they&#x27;d know you opened it, but if you put the pentalobular ones back on before going in, they won&#x27;t be able to tell.
