My iphone 4 only turns on when plugged into a charger?

My iphone 4 only turns on when plugged into a charger.

Previously, it had minimal water damage but I successfully got it in working order - restored it, dl'd apps, made calls, played music fully functional (or so I thought).

There is nothing wrong with the lcd, visually, or phsyically, I am able to see and flip through apps.

On the flip side, once I unplug the iphone from the charger, when it is inactive and on sleep mode, it doesn't want to turn back on, unless I plug it in to the charger. Note, as soon as I plug it in, it will turn the phone on whilst taking a picture of the screen... as if I pressed the sleep and home button simulatenously to take a photo of the current on the iphone. Everytime, it doesn't fail.

Now that the battery is fully charged, it won't turn on even when I do plug it into the charger.

I tested if my phone was really off by calling it but its not considering that it doesn't go straight to voicemail, it just continues to ring then goes to voicemail after the normal duration of not picking up.

Lastly, one thing I notice is that the backlight of the iphone 4 is still on for some reason, like a dim light thats only noticable when you the lights are turned off.


I know this is lengthy but I'm in need of help on pin pointing the issue. Any feedback would be much appreciated thanks!

I am having a similar odd issue. First of all this summer i took my iphone 4 to apple because my screen had quit. I could hear calls and texts coming thru but screen was unresponsive. I was a month out of warranty so the nice fella at apple gave me a 30 day warranty, then replaced my handset with a refurb. Saturday night at dinner i was on my phine and it died. I plugged it in thinking nothing of it and went to bed. When i wooe up after the charger had been on all night all i had was the black screen with the battery (red) and lightning bolt, meaning it knew it plugged in but still did nothing. So off to apple i go. They said i was out of warranty and the problem (never said what problem) would cost 170 bucks to fix. So i went and upgraded to the iphone 5 ( figured if i'm spending that anyways may as well be on a new phone). When I got home i tinkered with the old one with all the online suggestions i could find. (Cleaning ports, hard reset, putting into recovery mode, and checking indicators for water damage which there was none). Still only saw the battery symbol. I left it alone figuring i can sell off cheap and someone else can repair. Last night for kicks i plugged it in again and it came to life! It is in recovery mode (needs to be hooked to itunes to regain functionality) but showed 100% battery charge. I went to show my bf and realized an issue. If its not plugged into the wall adaptor, it wont turn on. I figured then that if i can get it plugged in and pull it up on itunes maybe it would be fine. When plugged into the computer it wont hold enough power. It thrns on shows the apple for 30 seconds, shuts off. My ending conclusion on my own is that it needs a new battery in order to be revived. Anyone think this sounds like a reasonable conclusion? Or will i be wasting money? If i can get it restored to functional, cheaply i can give to my bf (his pos lg phone is almost toast) or sell it.
