Why is my iPhone 4 not turning on unless it's plugged in?

Why is my iPhone 4 not turning on unless it's plugged in?

I recently replaced my cracked screen. I haven't had any problems with my phone at all. It charged, and I could call and send/receive text messages. Then, I went to a party without bringing my charger, and it was dying. When I looked at my phone it was dead. I plugged it in, and nothing happened. The Apple logo would just show up. After a while, it would turn on— but the date would say that it's December 31, and it was constantly searching for 100% battery life. I unplugged it and it turned off. So, I tried again and did a hard reset—but it still did the same thing. I plugged it into my computer, but it would turn on to just the logo and then turn off and keep looping every few seconds. I keep reading on the internet that people are having this same exact problem, but no one has answered them.

Sumera Ahmed, the first thing I would suggest is to replace the battery. Also, check the dock connector to make sure that there are no broken or bent pins.

"Two main issues may have happened to your [URL=http://www.forevermac.com/category/apple... |iPhone]:

1) A Dead battery, which means that it simply won't even hold the date/ time. There's always a small amount of charge left in the battery that ensures it maintains the date/ time. I suspect this is fed by battery and not the actual charger- hence it won't power on properly from the mains. Replace the battery.

2) The Power Management unit is corrupted/ your OS is corrupted. Far more unlikely.

I would replace the battery to see if that fixes it."

"i had this problem, I went out into town on the weekend, I ende dup quatting for a wee and it had dropped from my lap which was only 309cm off the floor.

It wouldn't turn on, yet I knew I had around 50% so I called it a night and got picked up. Thinking I was a little bit too drunk I thought id put it on charge in case it was actually dead..

It turned on once I put it on charge! I could not tell you how happy I was with it! but then I realised my phone was saying 100% then I knew there was something wrong, I took it off charge and it turned off this did my head in!

I pressed really hard on my battery so it could fit back in place and surprisingly this had worked my phone was freely working off charge! I was very happy! until today. it fell off my lap and down the side of my seat in my car, (which isn't far down) and now It wont work unless charging, iv tried pressing down on my battery and it works for about 5 minutes and then switches off again! :l APPLE NEED TO SORT THIS OUT! but yeah if anyone else having the same problem just try and put pressure on the battery and push it down as hard as you can so it fits back in place. Hope this helps:)"

"By squeezing the lower left corner you are excerting pressure on the battery connector which probably has a dry joint. Take the back off and put some card over it, when you slide the back cover back on it , it will put pressure on the connector and hold the joint closed.

I have the same problem too, but I think another factor that causes it is the memory. Mine's almost full which I think causes also the lagging that prevents the display to turn on. Try deleting some apps to free up your memory storage.
