Harder and harder to turn it on
My (out of apple care) iPhone 11 Pro Max stays on black screen after a few hours not being used (most likely running out of battery).
It used to respond OK to the Volume-Up, Volume-Down, Side-button sequence, but not anymore. Now it stays black.
Last week it "magically" turned on again after 2 weeks untouched (connect to power screen). I took the opportunity to do a full reset (Recovery mode, not DFU as I couldn't get it to switch in DFU mode).
But It did it again: now I can't turn it on, no button sequence work, looks like it does not even charge (does not run hot, neither on several working plugs, nor wireless).
Call to Apple helpline didn't help beside they wants me to pay an excruciating amount of $$$ to get a replacement :-)
Anyone having solved that problem before?
Thanks in advance !
