The graph represents li ion battery in general as note2 as well as most phone using li ion. So it is valid
Only difference between different brand battery is the cell quality but even if battery quality is good, will have similar charge cycle reduction as lousy quality ones. Just maybe not so severe drop
I know note1 issues cuz many ppl buy from me shows me their bloated battery. Not a few cases. A lot of them. And most I ask use less or about 1 year
Fat battery points to li ion cells already being damaged by over charging. This is mainly due to the ic that supposed to protect that cell becomes defect after certain period of usage. With no ic regulating the charging, the cell bloats
Now why the ic failed? I don't know. Can be the ic quality and note1 specific issue. But pumping 4.35v will stress the ic more than 4.2v in principle (of course if note2 use much better quality ic will have less problems)
Actually when I started the question , I just want to know if note2 battery technology already taken a big leap compare to note1 that now Samsung allows it to be charged to 4.35v or there is no actual leap in technology, just that Samsung wants to boost battery life (4.35v will give you better battery life compare to 4.2v) in short term to show note2 is great but later we will see faster defect
I just curious if anyone knows

My very uninformed answer is that Samsung is probably not the only one with >4.2V charging for the latest Li Ions. I was searching out 18650 cells a few weeks back, and there are some which charge at 4.35V as well. So it could be that the latest charging designs call for input voltages up to 4.35V, which might mean that the cells are designed to those parameters.
