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

Smart phone batteries have doubled or tripled or more in capacity during that 10 year period. The phones are more energy demanding now (processors, sensors, high refresh rate screens, comms, background apps etc etc etc), and we use them more than ever before. That’s why you aren’t seeing a practical extension of battery life. THe tech is improving for sure.

Galaxy S3 – 2100 MaH battery (phone I had way back)

Redmi note 10 pro – 5000 MaH battery (Phone I have now)

​

Also, charging is much faster than it used to be, and batteries don’t like being at maximum charge for long periods. Thus frequent, brief top ups are also optimal for battery health and user experience, while limiting the size the physical size of the battery itself
