No Li-ion battery is 100% safe. Batteries in sealed mobile phones are mostly of a pouch type. They are cheaper to make than the rigid/slab type, but require some extra handling and installation precautions.
Pouch battery may swell a bit during charge/discharge cycle and the battery compartment allocated in the phone should be large enough to accommodate it. Pouch batteries are getting thinner, to fit into thinner phones, which makes them more vulnerable to physical stress and overheating. Coupled with rapid and wireless charging, which tends to heat up batteries, it is no wonder the manufacturers are hitting the Li-ion batteries' limits. Btw, wireless charging is a fancy name for your mobile phone playing a secondary winding in a transformer.
Until battery technology improves, safer way of rapidly changing the charge status of your mobile phone battery is to get a phone with a removable battery and carry a fully charged spare one to swap when required. At the moment, a battery is the weakest point in a phone and one of the first components to either fail or under perform.
There is a report from Bloomberg saying "The original batteries that Samsung used for the phone were "slightly too large for the phone's compartment." The battery components were sometimes pinched, which could cause a short circuit, the safety commission said when announcing the recall on September 15th."
Looks like the replacement Note7 didn't get its battery compartment increased, as everything is too tight anyway, and its new battery didn't get smaller in size, as that would reduce the battery capacity.
This wasn't faulty battery anymore & could be faulty hardware also..
Samsung only think about profit and not for is fans. amoled display may be the best but only for six months and what?new phone.TouchWiz in a few months crashes,Note7every month a new phone.

Shame on people who comments like this. I no longer support Note7 too but I dont want to humiliate Samsung either. I still have my humanity intact. You talking about moral duty yet you have no moral yourself. Anyway, to all people out there, please return your Note7 and change to an iphone or something that doesn't explode. I dont care about this phone anymore. There is no saving it. Good day. Move on.
I guess the market is not ready yet for 64gb base model phones... Sad
this is a big scratch for Samsung, I'd stop the note7 production a long time ago and keed with the S7 Edge that is a very amazing phone, and wait until the new wave of phones with a S8 and Note 8 for a clean re start up
I was so hyped about note 5 a year ago. Then i saw rumors about galaxy note 7 , not note 6. But guess what. I never thought that sammy's batteries will be that bad. RIP samsung. I hope the S8 is coming "safe".
Stay away from these overpriced pieces of junk.
This is pathetic of Samsung. On the first recall did they do enough tests to ensure it's safe for use after the replacement. Maybe something else is at fault that spark the battery. Back to the drawing board, Samsung.
I can't wait till Note 7 finally comes to Europe, it's gonna be so cheap :)
I'll get a great device for a little money

Harakiri "Hurry's Kind"
Even two or three months delay for releasing was very better than this Century Big Tragic Batteries Story!
Samsung! Close your eyes on apple forever.
Hurry, outcome: unknown problem in your batteries, "Phantom Batteries"
