    Battery quality degrades while being at 100% charged for long periods of time anyways. So even if you are accurate about this bypassing battery theory (and you're not), it's still bad practice.

    I've decided to never charge my phone again because I don't want to wreck my phone. I've got it on Ultra Power Saving and I've put it away in a drawer so I don't get the urge to use it because we know that using your phone has the potential to wreck it. I'll check on the phone once a day and if it has no power I'll have no choice but to get a new phone and start the cycle again. This phone business is sure hard on the wallet.

    The problem is that you leave it on. Turn it off and boot it up once a week to check if it has any life left. When you're done, turn it off.

    If you are using a certified Quick Charge 3.0 charger with a compatible device, there should be no damage to your device. Quick Charge 3.0 ha a new feature called INOV (Intelligent Negotiation for Optimum Voltage), which allows for a better power output and a more optimized charging cycle by dynamically adjusting the charging voltage over the battery charging cycle. However, if you just use a Rapid charger that you by from the side of the street then yes that may cause damage.

    With regards to the Qi Charging. Many Qi chargers today have maximum output of 5V/1A which will charge a Galaxy S7 from 9% to 100% in about five hours. BUT with the new Qi Fast charger, your Galaxy S7 can be charged from 9% to 100% in just over two hours.

    So even if you use the Fast Qi charger, its still going to be slower than your normal Quick Charge 3.0 cable alternatives. So i wouldn't worry at all about any sort of damage to you phone. I use a standard non quick charge, charger for my Blackberry PRIV which has an output of 1,300 mA and the Qi wireless charger has 1,000 mA.
    So, the Quick Charge 2.0 that the Edge uses needs the 3.0 charger to benefit from the INOV update?
    Disregard, I see the INOV feature isn't available on the 2.0 that the Edge uses

    There are plenty of sources and studies for this. Please research these studies and let us know if you're still unconvinced.

    Actually no, once the battery is fully charged, it is bypassed and the charger powers the phone directly... It's why the phone is cool when removing it from the charger in the morning... (Unless, if course the phone is not "sleeping" for some reason... IE background data or an app running all night... In that case it might be a bit warm.

    Bottom line, there is no issue with leaving the phone on a fast wireless charger overnight...
    It trickle charges when 100%

    Sure, fine. I stand by my statement.

    ...And sleep soundly every night as my phone charges. 😉

    Yes it was a smart-*** move and I am sorry about that. Please accept my apology.

    But here are the problems....

    1) Yes Fast Charging will heat up the battery and cause it to degrade faster. How much faster than a 1A charger? IDK.

    PROBLEM - Over 13 million S7 edges are in the hands of customers. The box comes with a quick charger only. So either Samsung is knowingly bundling an accessory that wears out the device faster, ensuring the owner will then upgrade every year to the new shiny thing, or it is safe to use. Which is it?

    2) Yes keeping the charge at 100% for prolonged periods will degrade the battery. Degrade it more than discharging from 80% to 40% a few times a day? IDK.

    PROBLEM - People, in general, charge their stuff overnight. And this is a mobile device, so going on your way with 100% charge is ideal for a true road warrior. And personal experience says keeping it at 100% does not significantly degrade the battery (I had an iPhone 6s+ 1.5 years old and with keeping it on charger the battery still had 92% capacity when I gave it to a family member).

    3) Sealed Batteries and "thin is in" like on the S6 and S7 lines have created the need for fast charging, and has let grown men wear skin tight jeans, and these men have no time to wait 5 hours for a charge, because they take 2.5 hours to squeeze one leg into their pants.

    PROBLEM - See number 1

    I agree with all three of these observations and don't know the answer to whether or not fast charging is actually worse or if staying at 100 is always worse, that's a study that to my knowledge hasn't been publicly published. Here's the thing though - on the 100% vs 80,40 whatever - my typical advice to people is, "try to do shallow discharges if you can, but if it's not practical, it is better to charge it to 100% and then go than it is to let it die from not enough juice. By a lot. Even if that means leaving it on the charger overnight".

    To be honest, when I saw the battery capacity of that iPhone I gave away was at 92% capacity, well, I was expecting it to be higher. I have no idea what a typical battery capacity is after x years, so I have nothing to compare it to. Maybe I'll check those older devices I have just for fun.

    So I'll admit that maybe there is something bad with keeping it at 100%. That is 8% loss on a 2750mah battery keeping it (mostly) plugged in and fully charged for 1.5 years. So if I had kept that use case going, at 3 years it would be at 84% capacity. It would still be usable but range anxiety may be a factor.

    Note 3 and S5 we just wouldn't care and buy a $20 replacement. I don't think we will ever get that again. I don't keep devices for 4 or 5 years, but I know some people do, so it is important to prolong it as long as you can.

    For sure fully discharging and recharging like you said is the big killer.

    Ever hear the term "planned obsolescence"?

    You are talking about a phone company which sells devices with a target lifespan of about two years. They don't upgrade the firmware more than once or twice per model, they don't recall a badly-made device unless it is literally exploding in people's hands, and they aren't even making them with user-replaceable batteries anymore.

    A faster charge is a selling point, never mind that it will shorten the lifespan of the battery from say four years to two-and-a-half; the phone will be replaced in less time than that.

    I would argue those decisions could be in response to public practice rather than driving it. If you knoe consumers average an upgrade ever 25-30 months, supporting devices for 24-36 seems obvious, though some companies choose to support for 18 months. Devices would be designed to have acceptable performance for a similar period. And obviously a manufacturer would have no interest in trying to make the consumers keep a device longer, they'd want to promote patterns more reminiscent of apples annual upgrade.

    I agree: the pace of innovation coupled with the two-year contract that most providers liked (until recently) pretty much drove the target lifespan.

    I will put it this way... One of our mods had his battery replaced the other day on his 6P and in the battery shop they had a poster on the wall that was realistic in the sense of common use but at the same time still standing by the "Keeping it at 100% / discharging is bad" facts.

    The poster said..

    "While charging to 100% overnight is not the best practice... It is still better than a full discharge".
