Why can't they invent a phone battery that hardly ever needs to be charged?

Can't they invent a battery that would last at least a week??

    The phone manufacturers probably could supply a phone with a battery that would last a week or more, but we would he  ahve a situation where the battery would be more expensive than the phone itself

    Good idea but it would be bulky / heavy and out of most people's budgets.

    They do make batteries that last at least a week. Heck, the battery in a smoke detector lasts a couple of *years* before it needs to be changed.

    They also made phone batteries that lasted a week easily, but that was in the years before smartphones. The more things that they do, the more power that they need. It's a balancing act between power drawn by a device and the power supplied by a battery and the size and weight of everything.

    In other words, they could make an iPhone or Android battery that lasted for a week, but it'd weigh a couple of pounds and probably not fit in your pocket.

    That would be almost impossible as energy gets depleted rather rapidly im sure elon musk would love that though

    Get yourself a 20 kilo battery and it will last for weeks.

    Researchers are trying, but battery technology has a lot of roadblocks.  Furthermore people will generally prefer a smaller more powerful phone that lasts a full day vs a larger less powerful phone that might last a week.

    1. Longer life batteries cost more and people don't want to pay for it after a certain point, since for most people charging overnight is not an issue.

    2.  Bigger batteries add bulk to the phone that people don't care for.

    3.  Physics:  Battery tech has largely stalled.  Scientists have had a very hard time figuring out a reliable new battery technology that lasts significantly longer.

    That wouldn't make them much money would it.

    It all comes down to the capacity of the battery, and there have been billions of dollars investing in batteries with more capacity.  The problem is they then get paired up with devices that just make more power demands and you move no further forward!

    *Still using my Moto E4 Plus, with it's 3-4 day battery capacity!

    Yes, of course a phone could have a battery that would last a week between charges --- 

    if you didn't mind the phone being two centimetres thick to accommodate such a battery. 

        

    It could be done today if the public would buy it. 

        

    Don't hold your breath...
