Like how does this happen? let's say you own your iPhone for 2.5 years and saved up to at least 300 cycles of charge used and now your battery's capacity is at 80%. How do you experience this? does the iPhone goes from 100% steadily to 20% and then it automatically shuts off at 20% while the battery bar shows it still has 20% left? or does it rapidly go from 100% to 80% very fast and then goes steadily from 80% to 0% slowly then shuts off?

If you have any first hand account or have any information of this, plz tell me. Thx!
 
As said above, the time it takes to go from 100 to 0 will just gradually become shorter. It won't die at higher percentage, or discharge more rapidly at just one part of the cycle.
 
For most, it will take several years for that difference to become noticeable.

My 6+ has 98% capacity with 154 cycles after 15 months
6S+ has 97%, 44 cycles after 7 months
6S has 98%, 47 cycles after 7 months
5S has 87.16%, 297 cycles after 2.5 years and I still can't tell any difference in battery life.

The battery would not drain in a gradual manner if it is 'old'. It will hit some %, say 20%, and just power down. When this happens, just get battery replaced. It is better to have it done in Apple Store

That is not true. While what you described may happen, it's a result of a calibration error. What you need to do is plug in the iPhone for a few minutes, then power it on and you'll be able to use the remaining battery life.

Only 154 cycles after 15 months. How???
 
I'm doomed. It has 286 cycles in just 8 months according to Battery Life app (am I reading this right?). 6s Samsung chip.
 
Don't you use it at all?!
Every day. With my average usage, yes, the battery goes for several days. I don't play any games, just apps such as Facebook, Instagram and a few other apps. You can see in the screen cap below, it does not say that the phone has been plugged in since last charge. This is on one charge.

How do you experience diminished battery capacity on iPhone?

Simple, leave phone on sun soaked dash of car every day for a week. Guaranteed you will experience diminished battery capacity. If it even works at all after that.
