IPhone 4 not switching on or charging

So I have an iPhone 4 and I'm pretty sure my phone died today, as I went to charge it later on, it would go to the apple sign as soon as I plugged it in to charge and then it went to my passcode lock screen and then went black. It did the repetitively until I plugged it out.

I plugged it in to my other computer with a different USB charger, and now it doesn't come to the apple sign at all, it just stays on the charging bar in the middle of the screen with a bit of red and will not charge or switch on at all.
I've tried holding the lock button and home button at the same time and still nothing.

This happened randomly, and I would really like some help if anyone can give me some advice!

I'm sorry but I think it is time for you to upgrade or if you don't have the money wait 4-5 days on the charger sometimes things like this sort themselfs out
