Anyone tried Charging One smart phone with another's Charge? Just curious whether this is possible..
-
I had this idea since I have one old non smart phone, and I have a SONY XPERIA. I'm just thinking if it's possible to charge one smart from with power from another smart phone.
Depends on the connectors, voltage and current requirements. If the connectors match (and they use the same polarity, most do, but is it a VERY good idea to check) then check the voltage: if the charger gives too much, the phone may not cope with it and could be damaged. The other fun and games is the charge time: some phones (Apple, for example) and tablets use a high current charger which signals availability to the phone via the connector - if it's a good 'un, then the charge will take an hour, say. If it doesn't get the right info, the charge can take 20 hours. (My Nexus tablet is like that: high current charger and supplied short cable is 1 hour for a full charge, change the cable for a longer one and it's all day and night...)

You'll just end up with two partially charged phones - if you have one full battery and one empty battery and connect them together in some way, they will equalise their charges, with some loss along the way caused by resistance in the cables etc.
It's well known that if all the cat videos and porn disappeared from the internet there would be only one site left and it would be called whereareallthecatvideosandporn.com

Useful when one is about to die. So some share would give some chance to make some important work in it.

If it has got the standard micro usb connector, pretty much any charger that fits is going to work as the voltage/current it part of the spec. The dire warnings about using only "Sony" chargers are there in case you use a cheap adapter, it fails and blows your phone. Because of the warning, you can't get a replacement from Sony. That said, I've used cheap chargers on my phones without problem

That would be great to have Micro USB to Micro USB charging, I wonder whether that is possible? In my case I have Samsung older phone and Sony Xperia. I would love if I could charge Sony from Samsung when needed because I'm a heavy Xperia user and battery is draining fast. But I'm afraid whether they will get damaged if I do so.

I did that sometimes, never had problems (two phones with micro USB)..

Please let me have some ebay or amazon link to find that cable? or you made it yourself? I couldn't find that.

Came included with phone, one is even an old HTC cable I had, still worked on the new NOKIA.. Better not do it yourself, probably the specs are not publicly available..

I think what he wants to do is charge one phone from another phone, not with another phone's charger.

Taking the power of one battery to the other battery? Ah, he doesn't have any electrical power then where he is? His computer must be than a laptop with direct satelite connection which will soon have the same problem.. :)

I wouldn't have thought so. The sockets will probably let power in, but not out. A single transistor in the circuit would ixnay it, and there are probably several.

I usually charge my smartphone batterie with a usb-to-copperCable yes you read that right ... i wanted to flash my htc sensation but in the mid of the flash the power ran out so i had to recharge it ... if you flash a smartphone and you are not done with it - it wont charge so i had to improvise ... cut off the cable and connect the wires to the batterie ... half an hour later i finished the flash ... I am not MCGyver but you can call me so :-\
is this a signature ?

I think it is more of a conceptual problem. Old phones have batteries that last for days, smart phones last for hours. If you are traveling with both and your smart phone gets low can you top it up with the juice from your old fashioned one?

You mean use the old fashioned one as a charger? I don't believe that would work: the phone plug (which is physically on the device) is only "eating" current, not "getting it out" as far as I know. (could be wrong so)

AFAIK USB cables with two of the same type of end connector (both A (PC/power plug), or both B (device)) violate the standard; and the odds of one of your phones having circuity to drain its battery to charge something else using an invalid cable design are just about nil. It'd add volume and mass; both of which are highly constrained in a phone.

That's only because old phones were used a lot less and used a lot less power when they were used. ex My '04 model year fliphone's OEM battery is only 1.1 amp hours; vs 2.6 for the GS4

I use a FREE charger most of the time - a free USB port on my desktop ;)

The reason for my thought was, the ability that a smart phone can power up a USB Device (e.g. USB Pen Drive) and read it's contents and the ability to charge a phone using a USB power input. I wonder no one has tried this. Who likes to ruin the smart phones... ;)
