Completed the iPhone 5 battery replacement and now my power (sleep/wake) button no longer functions. Is there a connector I might have accidentally dislodged while removing/reinstalling the 3 connectors near the power button? Or some other damage I may have done? Thanks -Ray
If you pryed the top part of the battery then you probably have partially damaged the sleep / wake ribbon cable flex assembly. There is one smaller connector near the 3 front panel connectors, that one is for the power / sleep or wake button along with volume and vibrate. Note that if the battery isn’t glued down it can damage the cable too. The cable runs right under the upper part of the battery.
