(sorry if I picked the wrong category, I'm still relatively new to this site) The idea would be that phones could have the option of adding rechargeable batteries into it, aswell as a separate charging cord. With this, a person could have 1-2 rechargeable batteries plugged in while they're somewhere else, and instead of charging it overnight to get back to 100%, you can put another battery in and instantly get back to full charge, like a console controller. If someone forgot to charge overnight / is just online alot, it would be an extremely useful feature. I dont know how this would fit in a phone, but our computers used to take up entire rooms so eventually I imagine it could be possible

Phones with a removable battery and alternative solutions https://www.android...ble-battery-697520/

       I hate to sound super old when I say this, but here we go anyway. This idea is perfectly sensible, so sensible in fact that it's just how phones used to be.   

       At first, mobile telephones were massive analog power hungry things that needed to be plugged into your car or have a massive separate battery weighing many kg. Then, they moved over to digital. Something like the Nokia 3310 <link> was pretty ubiquitous. It had a removable battery, but that didn't really matter as it had such a small, low power screen and so little computing power, it's battery lasted in the order of a week.   

       Then, they started piling features into phones: cameras, large color screens, GPS, Bluetooth. The first smart phone I had was a Nokia N95 <link>. That ran through its battery in half a day, if you used many of the features, GPS being the worst. So, it was common to buy a separate charger and extra battery so you could keep a spare <link>. There were a few things wrong with this, 1st, the batteries weren't designed to be carried around. All the contacts were close together on one end and could short on some keys/change etc. in your pocket. Then, to change the battery, you're turning the phone off.   

       That led me to suggest the dual battery phone <link> so you could keep the phone powered on while switching batteries.   

       As smart phones became more sophisticated, the batteries became more integral to the structure... it's more space efficient to package a non-removable lithium ion cell.   

       Then, the external power bank came along and everyone realized that it's more convenient to have another battery that can charge the first battery without turning the phone off.

       What [bs0u0155] said, along with noting some newer phones do offer removeable batteries. Somewhere in the middle of that mess are things like Apple's Magsafe battery packs - not integrated parts of the phone but firmly attached while in use (rather than hanging off the end of yet another cable).

       //some newer phones do offer removeable batteries.//   

       Good to know that's not completely dead as a feature. I think there will always be a small market for them. At least while there are groups of individuals who aren't going to relinquish their phone but want to be in the room with interesting and highly sensitive information/things. The same people might also be among those who absolutely need to know if their phone is off.

       About a hundred years ago, I had a Nokia 6210, paired by infra-red to a Psion Series 5 computer so I could do emails out and about.   

       The best thing I liked about it was that you could put your hand in your pocket and press the battery release button to kill the phone totally (by sliding the battery away from the contacts) instantly and without anyone noticing. I also remember getting a spare double-sized high capacity battery which would run it for a couple of weeks without needing charged.   

       The Psion computer ran on 2 AA cells so in an emergency you could go to a wee shop and buy a couple and carry on working.

       [poc] I remember those double-sized high capacity batteries. I had one for my Motorola phone in 1995

       //put your hand in your pocket and press the battery release button to kill the phone totally//   

       Working in the opposite direction, I had an old Samsung that with a press of 2 keys would give you a fake phone call a few seconds later.
