@Terrance, I don’t think a power bank is a good idea here. All they can do is ‘charge’ the battery and in my experience they
barely keep the mAh from falling when the phone is in use, let alone putting more charge into the battery.
I think what pere carrizo wants is to ‘run’ the phone, possibly without even a battery present, bypassing the charging logic completely.
I’d like to see a variation on this idea: provide connectors for a 9v(?) battery, which you attach temporarily in parallel with the
extant, so you can change the battery without having to reboot the phone. What this’ll do to the Coulomb-counting, I don’t know.
@Terrance, thank you; I’d forgotten about temperature sensing and identification.
I’ll have to do a dumpsys battery to see what info the OS is seeing from the combined battery.
I have paralleled one wire (other than the -ve line) and this seems to enable the NFC antenna (mounted on the S5 battery) to work
I’ve just successfully paralleled two Samsung Galaxy S5 batteries. It works but it’s too early to tell what the additional capacity will be in practice.
The voltage of the two batteries reported by my DVM is 4.8v (!)
I couldn’t relate the pin names to what I could see under the PCB cover, so I soldered the two + terminals
together with a solder blob. I also connected a wire between the two negatives (pin 3; there are four pins)
On this model, the NFC inductor is laminated to the battery to get it as close to the outside world as possible; I got this working
as well by removing the NFC inductor from the “inner” battery and wiring together one of the other pins, so as to connect it to the
outer battery. I’ll try and get some pictures but I don’t know to upload them in comments.
I am also going to try and put in an aftermarket wireless charging pad. I’ve had one before, but the thicker battery in this case will
change the geometry a bit.
