those looking for EU original 2A travel adapter, fyi, next week stock should arrive

and also will be bringing in IRON MAN battery cover (also will have cute hello kitty too). lol

guys, a bit off topic question

how to put in the youtube link properly?

lol. thx bro

it works

i put the entire hyperlink in it

btw, possible to resize the youtube display?

hi all,

you guys know that note2 battery is charged to 4.35V instead of general practice of other phones which is charged to 4.2V

In principal, if all things are the same, charging to 4.35V reduce battery life by more than half

so my question is, anyone has an idea if the samsung cell is so great compare to others that it can withstand this higher voltage or can we expect shorter life span for note2?

By battery life I mean how long it can last before the battery finally degrade or died completely

In short charge cycle reduced by half

I mean to point out the comparison between different max charge voltage impact of battery life, not the absolute value

Anyway if want to do interpolation, note1 battery many user complain their battery fat after only less than 1 year use

Also doesn't match the graph on absolute value

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

That's possible but btw bro. Even note2 if you have the right charger can go up to 4.4v as well . Will get even better battery life but consequences is ...... will die faster

Lol.

I just trigger the discussion because a bit curious only on battery tech

I can't forecast when note2 battery will die. Haha

Bro that graph is generic only ler

Most likely they use some 18650 cell

May not come from Samsung

Again that graph main purpose to show the effect of higher charging voltage impact relative to lower ones

Don't take the numbers on absolute terms

Will be interesting to see how would note2 (4.35v) compare to note1 (4.2v) in terms of battery life

bro,

you sure?

Look at charge cycle #400. Didn't see the 4.35V anymore

yes bro, i know note2 3100mah is not in the graph. again as stated, this is a generic graph to show the relative comparison between 4.2V and 4.35V max charge cycle.

and again, even if there is a 3100mah graph, it may look different for note2 battery (original) because the quality is different

So, pls don't take the charge cycle numbers literally and apply it for Note2 to predict how long it can be charged before it died off

###########

I give a simple example. Controlled environment experiment for a specific car maker shows

1) 30 litre petrol tank car can go 300km
2) 10 litre petrol tank car can go 100km

Now if take a car from a different maker with 40 litre petrol tank, will it be able to go exactly 400km ? this hard to say. can be 400, 450 or even only 350 because it depends on how efficient is the design

BUT can we agree that with bigger petrol tank, we can drive further? Yes, we can say that

##########

so that's what i am trying to point out. i wouldn't say from the graph what's the actual charge cycle will be for Note2 but we can agree charging at 4.35V in general will reduce the charge cycle compare to 4.2V

hope this clarifies things

##########

and as stated in my earlier post, i was more interested to compare Note1 (4.2V) to Note2 (4.35V)

From my experience (selling replacement batteries to those pregnant ori batteries), lifetime is about 1 year.

So if Note2 battery is indeed a positive leap in technology, then we will see similar or maybe better charge cycle compare to Note1

BUT if it is still the same battery technology as in Note1, then will have lower charge cycle for Note2
