iPhone 3G shuts down when locked, what do I repair?
My 3G will shut off when it goes into lock mode. This does not occur when it is plugged in. The power button is also unresponsive whether plugged in or not.
I have already taken it completely apart and made my best attempt to clean everything with isopropyl, even the underside of the power toggle.
When this problem first came up I also noticed that upon every single reboot (which only happens after I plug it in), the battery would be in the red zone, and would require charging time to reach green again. Due to this, I ordered and have already replaced the battery, many thanks to ifixit and the guides provided. Since then I have not seen a depleted battery upon reboot, great, one problem out of the way. On to the next.
I was condsidering replacing the headphone jack assembly, assuming my power button was un-salvageable. The only thing staying my hand is the $50 price tag for the part and no guarantee that this will also fix my shut down problem when the phone locks. The headphone jack, mute toggle, and volume buttons are operational, it is only my power/lock button that will not respond.
The 3G will wake up when locked if it is plugged in by use of the home key, but if I let it lock unplugged I must plug it back in so that it reboots to turn on again.
I have completed several facory resets while praying to the technology gods, but alas, to no avail.
#1: Depleted battery upon every reboot (FIXED)
#2: Unresponsive power button.
#3: Shuts down upon locking when unplugged.
Does anyone have any suggestions for me? Does anyone think replacing the headphone jack assembly may fix the shut down problem as well? Is there a finicky way that I may have foregone to clean and reassemble the power button? Have I lost my first iphone to the ravages of time (over 3 years old) and a humid climate?
first off you can buy a headphone jack for about $5 anywhere on ebay, ifixit has good stuff but if it's prices are stopping you from saving your phone then buy elsewhere (sorry ifixit). I would try that first but I suspect this is the power ic..most phones when they sleep can be woken by home button too which is why I think it might be more than a simple headphone flex. As repair costs go it is cheaper and easier to do the headphone than the power ic so do that first
