You haven't even tried it and are talking about how its not efficient... lol.My knowledge of physics.
Every single source on the planet with any knowledge of low current wireless charging.
Ever wonder where that extra heat is coming from when you wireless charge your phone? That's energy that isn't ending up stored in your battery....
You can't convert electric current into a magnetic field and back without some pretty significant losses.
It's not a particularly efficient process.

No, it's just inefficient because it is inefficient - simple as that. I don't think it's a particularly bad feature - I do like the idea of being able to top off earbuds in a pinch if needed. Marketing it as being able to share power with a friend is a little disingenuous because it won't work that well in implementation. A huge portion of that energy you're draining from your battery to 'give' to a friend will just be lost in the process as heat. You'll be draining 10% of your battery to give a friend 5%. (The ratio will probably be much worse, especially if you both have cases on your phone.)
Honestly, it's just an example of a feature that sounds great but won't work well in implementation and people will be disappointed by it (except for maybe topping off earbuds or a watch that don't take much energy to begin with).
I'm not a fan of low current wireless charging in general. It is just a really inefficient technology that leads to further waste of energy. I prefer things that increase efficiency. It also takes like 10x longer to wireless charge your phone vs using a fast charger...
Sure sure, if it was Apple's it would be magical and would then be efficient. No point arguing really.
Use google messages. Or switch to WhatsApp like everyone else
It's funny.. but you forgot one thing.. it's Samsung, not Apple. Only iPhones have this weird behavior where battery strength drops from 80% to 15% at random.
It will be fine. I did and I never miss iPhone anymore. My rest of the family has iPhones.
They seem to be offering the $550 trade in for all the S10 models. Again, I don't believe most will get $550 for their phone once Samsung gets it in their hands on it and comes back with a much lower offer. If that's the case, I can get $550 for my iPhone X, spend another $450 on 10+, and then turn around and sell the 10+ for $900 unopened. That's a quick $450 profit for me. In essence, I would get $900 for a used iPhone X.
You are 100 percent correct, wireless charging is inefficient, so much lost energy in the process, but let's wait and see how well it actually works before making assumptions. For its intended purpose which will be charging accessories at a pinch it could work pretty well, lets say a earbuds battery case is 300mah, even if the S10 only has an efficiency of 50% . (i've read that it can actually be up to 80% efficiency btw) it will only drain 600mah out of the S10, with a 4100mah battery that's a hit that can easily be taken and that's a worse case scenario.
Why would anyone that can get the same deal buy the s10 for $900? I wouldn’t.
I believe you also need to get a new cable as well for £19 ish.
Because not everyone wants to trade a phone in. Some people keep their old phone as a backup. My point is that $550 trade in is probably too good to be true. They will get your old phone, evaluate it, and then come back with a much lower offer.
