I always hear since 10 years about new amazing batteries being invented, but in the end my iPhone battery today still holds only up for a day, why, where is the innovation getting lost?

Question

I am really wondering. so many technologies that i always used to hear about, but they never end up in new phones and stuff

Answer 1

If the processor (speed, number of transistors) and the display (number of pixels, brightness, size) had remained constant, then yes you would see longer battery life.

For example if you powered an iPhone 3G with the battery from an iPhone 15 Pro Max it would last for days. But you’d have the processor and the display of an iPhone 3G…

But processors and displays have NOT remained constant. They have progressed in huge leaps, and they consume more power.

This is balanced by improvements in batteries, leaving us with a phone that lasts around the same time.

Phone companies had to make a choice on balancing performance/display and battery life, and it was probably the right choice.
