I know It'd be better a solution to go to an iPhone repair shop with that.
Before I go I'd like to ask and hear if anyone having the same issue as I do.
My iPhone is not turning on now.
When I wake up in the morning I figured out my phone's off. It happens sometime as the existing Battery having some troubles before.
It wouldn't charge till 100%.
Usually it stops charging on 70-80% on average.
And turns off sometime while it had about 30-40% charge.
So I thought that was the issue.
When I tried to turn in on the screen didn't came up, I was just hearing the sound of the empty charging bip (you know what I mean, that warning sound while your'e phone having 10-20% charge).
Then I connected it to the wall charger.
The display is still blank.
Now I'm hearing the sound of charger connecting continuously/repeatedly.
It was just annoying.
So I turned the phone off.
And till then It's not taking charge neither turn on.
I have changed the battery then (as my friend got a spare battery).
Nothing happening.
Any idea would be appreciated.
Thank You in Advance.
