My phone is daad

Amit, you haven't given us much to go on here. I assume you're saying the phone won't turn on, is that right?

If that's the case, tell us more. Did anything happen to the phone before it refused to power on, such as being dropped, exposed to liquids, a system update,etc.? How was the battery life previously? Did it take a full charge and last a decent amount of time, or were you having to charge it frequently?

Have you tried a new charging cable and charger, or verified that yours works on another device? How about the charging port; did you examine it carefully for any debris or pocket lint that could be keeping the charger from being inserted fully? Have you cleaned it out carefully and checked for any bent or broken pins inside?

You might want to purchase an inexpensive USB ammeter to see how much power the phone is drawing when it's plugged in; that will help pinpoint whether it's a charging port or charging circuit issue if indeed it isn't getting any power.

If you want to just dive in and start replacing parts, I'd suggest a new battery and a new charging port, then reevaluate and see if that fixes the problem.
