How long would a smart phone charge last, with no use?

So now put in a sim, turn on WiFi and BT and put it in a tin box so it is constantly searching for a signal, and see how long it last then.

^ Only because it means you get to eat a whole Selection Tin of biscuits, before you can put the phone in there!!

pick up a free pay as you go sim, don't actually register or put money on it. Should still try to constantly handshake with networks.

Personally I've given up on wifi on my phone, that way it generally lasts me a week, but I don't really do much on my phone.

And your point is?

If you look at the power draw statistics for various parts in the phone its usually the screen,followed by the wireless components which draw the most power. Its why if you use a mapping utility or play any game which uses the modem a lot(like Pokemon Go or Ingress) it hammers battery life.

Just making sure any potential bias is disclosed and declared up front....

Cellphone batteries are like any other kind of battery, which means that if they go unused for quite sometime, they will eventually lose their ability to hold a charge. For example, if you have ever looked at the package of everyday batteries like Duracell's, etc..., you'll notice that they have an expiration date on them. Usually though the expiration date is quite a few years away, so in theory, they could still work 10 years later.

I’m afraid that is incorrect. Different battery chemistries have different characteristics. Duracell’s of the type you described are primary cells and cannot be re- charged and they self discharge over time.

Cellphone batteries are lithium ion secondary cells. They have very low self discharge and can be recharged many times - typically >500 , although they do lose capacity over time.

In this case, I think 12 days/ 5 hours (Assumption)

My s6's battery would probably die in a single day just on standby, it's quite shocking,

Generally speaking, it can be used for 3 hours under full charge.

[Laktog]

It should last about 20 days if not signed into any email or similar service that requires constant refresh
