The real reason your phone battery gets worse #LithiumIon #BatteryLife #shorts

[00:00:00]Your phone battery isn't broken. It's doing exactly what it was designed to do.

[00:00:05]And the reason goes back 200 years.

[00:00:08]You notice it around month eight.

[00:00:11]Charges faster, [music] dies faster.

[00:00:14]You think, did I break it? Drop it too many times? Leave it plugged in overnight? None of that.

[00:00:21]This is chemistry, and it was always going to happen.

[00:00:26]In 1800, Alessandro Volta stacked [music] zinc and copper discs soaked in salt water.

[00:00:32]The first battery.

[00:00:34]It worked once, then slowly [music] died.

[00:00:38]Sound familiar?

[00:00:39]Every battery since then has had the same core problem. [music] Ions move to create power, and every single movement damages the material they move through.

[00:00:50]Your phone runs on lithium ion.

[00:00:53]Charge it, [music] and lithium ions push from one side to the other.

[00:00:57]Discharge it, they go back.

[00:00:59]Except they never go back perfectly.

[00:01:02]Each cycle leaves tiny deposits.

[00:01:05]The pathway gets narrower. Capacity shrinks.

[00:01:08]After 500 cycles, you're holding a battery that's already 20% smaller than the day you bought it.

[00:01:15]No repair, no reset.

[00:01:18]Solid state batteries could fix this.

[00:01:20]They've existed in labs for a decade, but mass production keeps getting delayed.

[00:01:26]Meanwhile, your 2-year upgrade cycle keeps moving on schedule.

[00:01:30]Volta's battery died slowly, too. Yours is just doing it in your pocket.

[00:01:36]Follow for more things that frustrate you, explained.
