Wireless charging or USB charging

[caltroon]

Can I use a wireless charger and have a receiver in my phone and charge it wirelessly sometimes but other times plug it in with my USB cable? In other words, can I charge the phone both ways, but not do both at the same time?

Yes, as long as you don't try to do both simultaneously. This is true for any phone with wireless charging capability.
Does your S5 have the optional Samsung wireless charging back or an aftermarket coil installed?

 

[caltroon]

It's an aftermarket thing that goes over the battery. I got it on ebay and it's awesome - I use it for my original S5 that I had to replace because the charging port broke. I have an SD card in there and use the wi-fi to monitor our home security. I thought I'd try wireless since I had nothing to lose with the old one and it works great so I've ordered another from the same seller. I just wanted to see if I could have it in my current phone and either charge it wirelessly OR plug it in. Not both at the same time. Thank you for your response.

Just keep an eye on the temps with the aftermarket charging coil. I tried those on my S5 and they worked, but they created heat which was bad for the battery. After a couple of battery failures I gave up on them.

most phones these days....not sure on the older s5....the wireless charger will stop charging once, the phone is plugged in. my car charger does this. the car charger is only 10W...while my charger that is cigarette charger is 25w and charges the phone much faster. when i plug it in while it is wirelessly charging, a popup will say that wireless charging has been paused.

Yes, I never just lay it on the pad and walk away. The moment it's charged I unplug it.

But if the wireless charging capability is itself through a third party add-on (an aftermarket back panel for the phone) and isn't something the phone was designed for I would not count on it doing that.

 

[caltroon]

It's my original back panel - it's a piece of whatever the material is with a tab that sticks out over the two unused terminals at the top of where the battery is. I have so many batteries I'm not concerned if I overuse one and it dies. And actually the battery usage is great anyway so I only have to charge it every few days. As I said, it's only on wi-fi - no phone company sim card and no apps running but our home security and the minimum Android ones.

But you said in post #3 that the wireless charging thing was an add-on, or at least that's how it reads to me. If it's a replacement for an official Samsung part that ups the odds of the phone behaving sensibly (i.e. not trying to charge both wired and wireless at once) - though I don't think I'd risk it, and it sounds like you agree .

 

[caltroon]

I didn't know there is an official wireless charger for a phone as old as the S5. Yes it's an add-on. It's a rectangular thin thing that goes over the battery and two points go over two unused points at the top the battery. I lay it on top of a wireless charger. It charges. I take it off the charger. This is a phone that is useless for anything other than what I use it for.

There was an optional back cover sold by Samsung that had the charging coil built into it. The coil connected to the same terminals as used by the aftermarket add-on coils so I doubt the operation is any different. I don't think I ever tried to use both wireless and USB charging at the same time but it probably wouldn't have allowed both.

 

[caltroon]

If you saw my original post, I did say I would never try to charge them both ways at the same time. I just wanted to know if just having the wireless charger inside the phone would be a problem if I plugged the phone in a regular charger. That would not be for the phone that already is charging wirelessly. It would be for my current S5.

I own an S5 that I just use as an MP3 player now.

I can confirm what others said, the aftermarket charging coil does seem to over charge (and then bloat) the batteries. Even though the light goes from red to green, it still must be applying current to overheat the battery. I just use the USB cable now.

 

[Fox Mulder]

I wonder how it would work with the official Samsung charging cover, never got to try it. Unfortunately that cover made the phone too thick to use with a case which made it a no-go for me.
These days I have an S9 which has built-in wireless charging and it works very well. No excessive heating even with fast wireless charging, I have a couple of Samsung fast charging pads that have fans in them to keep it cool.

Hi Fox. While I have you on the line ... your suggestion re new battery for S5 (specs) Thank you, peter

That's a tough one. Since the phone is long out of production, the best option (which would be an OEM Samsung battery) is no longer available. Any "Samsung" batteries you see advertised will either be fakes or ancient old stock that have been sitting around unused for years. Either way you don't want those. There might still be aftermarket ones available but the quality will be hit or miss and there really isn't any way to tell. The only advice I can give there is to stick with replacements with the same capacity rating as the original battery, any batteries advertised as 'high capacity' that are the same size as the OEM one will be bogus.
