Wow! I know this thread is older but I thought I should say this worked for me as well. My Iphone 6 has been off and in a box for a year - I decided to sell it but it wouldn’t turn on. The screen was completely black with no charging symbol. First I cleaned out the Charging Port, Then I used my blowdryer for about 30 seconds on each side. I tried the Reboot ( Holding down Home & Power Button for 30 seconds) - nothing happened YET Then I plugged it in to my laptop - and the charging symbol appeared. I’ve had it charging for about 10 mins and it’s WORKING The heat really did help - I had it changing for a full day previously and tried the reboot several times and nothing. Thanks y’all!
