Just about 1 year lol so old.
Meanwhile battery tech hasn't changed in over 10 years. Yes, leaving your phone plugged in overnight sitting at full charge WILL take it's toll on your battery health. Note, I said health not life. People think this means they won't get as much use during the next day out of the charge, this is not what I am stating. Leaving it plugged in overnight wastes recharge cycles and being kept at max voltage (4.2v) for extended periods of time (8 hours a night) WILL burn out the cells faster, meaning in possibly a year or less you will see significant loss in battery health, leading to shorter charge cycles.
Please stop denying the facts. Yes in less than 2 years most people will have moved on to a new device, leaving their old battery sitting around collecting dust. At which point it's health won't matter much. But do not argue that it doesn't take a hefty toll on it when it clearly does, as has been proven time and time again through multiple studies and tests.
I'm not denying any facts, the problem is we don't know the real facts. We don't know the author's qualifications or where he got his information from or how old that is. What we do know is that the tech changes from generation to generation, and currently a generation is less than a year. This is not 10 year old tech.
I would suspect, based on my DC power supply background, that these phones do not do what the old analog supplies did, which was just dump power into the battery forever. Smart chargers sample and provide current as needed. They don't feed it continuously. Even the latest power tools - the lowest tech of hi tech - have smart chargers and the manufacturers tell you it's OK to leave them plugged in. I think Samsung is quite a bit higher on the tech scale.
Basically, we don't know exactly what the chargers in these phones are doing, but we do know that they're software controlled, and it behooves Samsung to make sure the battery is as good as possible at all times.
I got over two years from my last phone on the original battery and that was docked every night. I never saw a decrease in battery life and that was two generations ago. However, after saying that, I must point out that the plural of anecdote is not data. In other words, just because you or me or Betty or Fred had something good (or bad) happen, it's not necessarily true across the entire line.
I'd like to see the results of a few of these many studies, but only as long as they are based upon current battery and charger technology, else they are irrelevant. Rest assured that whatever the latest algorithms are and the reasons for choosing those are going to be a trade secret.
It all boils down to we should each do what works for us, and remember that the cost of a battery is insignificant over a period of 2 or more years. Only a small percentage of us will still have these phones come January of 2015 and you can be sure that a vast majority of them will be replaced while the factory battery is still good.
