iPhone 7 suddenly goes dead

My iPhone 7 now and again suddenly goes dead, can't press any of the buttons to wake it, can't hard reset etc, battery always between 50 to 100%.

The only way to get it fired up again is to plug the charger in for literally a second until the apple logo appears, then it starts and operates as normal.

Anyone got any ideas on this??

Have you tried the hard reset method for a longer period of time, like 20-30 seconds?

Yep, nothing, the only way to get it back alive is plug the charger in for a few seconds. It then starts up as if it's been turned off with the apple logo.

Just confirming.You do know the hard reset button combinations are different for the 7 right?
 
Let me just say that battery technology has limits if you use too few cells and make these cells thinner and thinner.
A battery has to provide a stable current to the voltage regulators at all times to ensure any device can run.
Every single factor, like temperature, power drawn from the cells, etc. will affect these fragile chemical containers.

What I'm getting at here: In the old days people build battery packs with loads of cells and thicker materials just because the quality and reliability was inferior. They had much more headroom to operate.

Todays batteries are designed much closer to physical limits.
As long as manufacturers continue the thinner, smaller and higher energy density road, we will see more and more products that either fail right from the start or will be electronic waste one year later.

This is sad news for everyone.
And it's not an iPhone problem at all.

Of course it's an iPhone problem. Are you saying it's washing machine problem?

You intentionally misinterpret my words ... fine.
It is an iPhone Problem today, but it's a design problem that is not specifically iPhone-only.
