I think that chasing into ‘thinnest smartphone ever’ at the expense of e. g. battery capacity or functionality (like being removable) is very annoying.
I was displeased when I read in the article that people were disappointed by the plastic back of the Samsung Galaxy Note 4. 
It was a very practical design, rubberized, providing decent grip to the hands, unlike the present glass ones.
The EV batteries are currently recyclable. There is an recycler in California. The main issue right now is that there isn’t enough EV batteries that have gone bad. They are holding up very well if they are liquid cooled.
The fire issue with EVs is way, way over sold. However, when it does happen, they pretty much have to let it burn it’s self out and pour massive amounts of water on the fire.
Any fire is going to release a lot of toxic fumes. Here is the USA, with the amount of guns and ammo, firefighters have to be concerned with getting shot when dousing out a fire. Anyhow, firefighters use portable breathing apparatus to deal with toxic fumes.
Yeah @user990, much depends on the chemical makeup of the lithium battery? If it’s lithium ion, you can use water, but massive quantities are required! If it’s lithium metal, you need specialist type D equipment… From what I have read about lithium fires, especially EV fires, the firefighters just let them burn, usually it takes approximately 2 hours for an EV to burnout, they will burn without oxygen, intensive use of water only has a cooling effect as it will continue to reignite… When I had a BMW i3 EV, Insurance premiums were excessively high, and only certain insurance companies would actually cover you, for me at least, approximately 4 times my normal premium, and I couldn’t fathom the extra cost, I now, kinda understand why, a complete carbon fibre shell, and a fire hazard…Tis also kinda scary, with the amount of large & small lithium batteries that I have around my house, several KW Hours… Cheers Kev 
Is this for real???
