Worst part is that battery technology doesn't have anywhere to go without some pretty extreme breakthroughs... They're limited by chemistry at the moment, you can't increase their efficiency and capacity without making them significantly more dangerous, toxic, and volatile.

Lithium ion batteries are pretty safe. If you look at a periodic table, Li is in Group I. Of you move down one period to sodium, you get a much more reactive metal. Lithium by itself reacts with water because all metals of Group I have a single valence electron. Water is very polar and pulls the electron towards it to try to satisfy its outer shell. Sodium explodes when it comes in contact with water. Potassium... well, even more explosive.

Those kinds of batteries have to be in compounds, normally Lithium bonded with another metal and oxygen. The higher the energy, the greater the output. But... the higher the energy normally mans larger molecule, which leads to bulkier and heavier batteries.

So manufacturers are stuck trying to maximize battery size so their phones can keep up with the lack in battery technology advancement. Start closing your apps and don't count on any breakthroughs soon. lmao
