I received the Verizon quick charge bundle yesterday. Quite a deal for the battery, the car charger and the new slanted Samsung wireless charger. It seems like the wireless charger is pretty snappy, but with no replaceable battery, what will using it do to the long term battery life of the S7E?
Is it OK to use it whenever? Like frequently putting the phone on the stand to get it from 90 to 100%? Or leaving it on the stand all day or all night? Any tips on how the wireless quick-charging technology works and its effect on battery life would be much appreciated. Thanks.
I don't remember exactly which thread but someone mentioned that fast charging would also negatively affect the battery over time due to killing the battery cells. Might be in the battery life thread..I slow charge mine overnight and only fast charge using my car charger.

maybe thats why even sammys fast changer is not very powerful??..

So I was a bit skeptical about practical use cases for the fast charging. I made a general observation after the first few days. It's currently completely not scientific. But it seems when I disabled the fast charging, my phone seemed to handle battery life way better. Idk how efficient the energy is when done via fast charge, but I've always heard that a slow steady charge is better for lithiums.
I figured maybe this could cover the impacts of fast charge and whether people have noticed similar things. (Day 4)

Looking forward to your findings!
I disabled fast charge the day I got it. Seems pointless to me since the only time I charge is at night. It's a cool feature if I need a charge in 20 minutes but the note 3 I gave my wife would charge in no time as well.
Battery life is great so far for me.

I've been testing this as well. I leave fast charging on and I'm seeing an easy 14 or so hours off charger with 4 to 5 hours screen time.
Fast charging is incredible. My last charge cycle I recorded was 56% to 98% in 28 min. That's about 1.5% per minute. Though I suspect soome non linearity as it gets closer to 100%.
As far as the longevity of a charge based on regular or Gast charging . There will Likley be no correlation. The charge circuit will handle the incoming current appropriately and the battery is built to handle it. I am a EE and am intimately familiar with battery technology. The charger itself changes its output voltage for fast charging (stepping up the voltage but lowering the current) and I'm at sure there is some software as well as special hardware controls in place to ensure the battery is charging effeciently.
The usual problem with charging batteries too fast is due to heat build up in the battery. However, these new batteries were developed to solve these problems. I wouldn't worry about it.
Here are my results with just over 3 hours of screen time

I love quick charge. Nuff sedd lol!
After a whole day on wifi in the office plus weak cellular signal inside the building destroys the battery, I plug it in for 15-20 minutes and I'm good for a whole night. Love it.

18 hours off battery, 4hrs screen time, and still 19% battery.
I wouldn't care if fast charging destroyed my battery every 6 months. I'd buy another for $20, but it's not going to do that.
I went back to the slow charger for overnight charging and battery life has been pretty darn good. When I use the fast charger it says it gets to 100 quickly but I feel it drops down way faster. Anyone else feel this way?
yeah, same happened with the note 4. I only use the fast charger when i need a quick charge. I use my old note galaxy tab s regular charger overnight.

Yeah. Fast chargers are great (the one included with MXPE is superb) but they're not meant for overnight-leave-your-phone-on-the-charger-for-6-or-7-hours-while-you-sleep type charging. Technically, the less you leave your phone on ANY charger after it reaches 100% the better it is for your battery.

This used to be true, but I thought it's been debunked with current battery technology. Recent source anywhere?
No source... IMO. (And the fellow XDA members that replied to this thread)

He was asking for the source saying it is better to disconnect your phone once it gets 100% battery...
It's been proven it has no ill effect over time, and after charging to full it will stop charging until it discharges enough to need a trickle charge, at which point it will trickle back up to 100% and repeat the process.
If you have ever had a battery pack shut itself off after charging your phone to 100%, it's because it finished charging and didn't discharge quickly enough before the battery pack shut off.

I never use my rapid/turbo/quick charger (or whatever it's called). I only use the regular old overnight charger. I get great battery life. I know for a fact that heat is bad for all electronic components including batteries as can be read about in numerous articles on the subject. However, I also wonder about rapid charging to 100% why would the charge not last as long? Unless something that is reading the battery capacity is not accurate when the battery has been rapidly charged?
I don't have any scientific evidence. I just find I get better battery life using the old charger and noticeably worse battery using the rapid charger
I use the rapid charger and the battery life is the same with or without it.

I agree with this, my phone was on 15% and I was about to fall asleep so I left it plugged in for about 9 hours, and it was almost dead with 2hrs SOT and 5 hours after being unplugged. But if I unplug it when it's at 80-90% it lasts me almost all day and into the night.

Same here. Rapid charge is awesome, and my battery life is very good as a business user.
I agree that fast charging is great for a temporary quick charge but not good using it to get your phone to 100%
Hi im a little sceptical about this wireless charging, as i had a Galaxy S6 with witch i used a 5$ 1A wireless charger (with original fast charger head ) and i think it ruined my battery as when the phone got 15% there were occasions where the phone would get from 15% to 2% in just a minute and after plugging it in it would go immediate 10%. Now that i have the s7edge i don't want to make the same mistake again i was thinking of getting a genuine "Samsung Fast Charge Wireless Charger Stand ", my question is does wireless charging affect battery lifespan (on the long run) or is it the same as using wired fast charging. I really like to keep the stock battery and prolong its lifespan as where i live i don't have access to genuine replacement parts and would get a chinase fake battery and i would lose water resistance. Also i charge my phone over the night.
Hello, after sending my s7 edge to warranty for terrible battery (2h Sot at the top after a clean install), i´m questioning if could be the use of wireless charging every night the cause of so fast battery degradation.
In battery health concerned, there is a difference using the wireless charger instead of normal cable charger?
And btw, a good Samsung wireless charger is better than a ordinary one?
I would also like information on this. I have used only wireless charging non samsung charger fast charging disabled in settings. My phone is almost a year old and it out still working well. Just curious about best practice for battery health longevity.

Yes, I'm also have quick charge disabled.
So, what kind of wireless charging? Regular QI, or the newer Fast Wireless chargers? The answer depends on that.
Batteries don't like heat. Batteries heat up when they are charged and discharged because of internal resistance. All those electrons flowing through the battery generate heat. The question is how much is too much.
Rapid charging (like QC 2.0 or 3.0) puts more power into the battery than normal slow charging. More power means more heat. And the closer to full charge the battery is, the more heat is generated. That's why all the rapid charge systems reduce the charging voltage and current as the battery "fills up."
Does wireless charging heat up the battery? For regular "slow" wireless charging, the answer is maybe, maybe not, but probably not enough to notice in any case. There are two things going on with wireless charging. The first is the wireless coils in the charger and phone, the second is the amount of power flowing into the battery. When charging, the coils generate heat. With a well designed phone and charger not a lot, but some. IF the coil gets hot enough, and is close enough to the battery, to heat up the battery, then it could have an effect on battery life. But the output of the wireless coil to the battery is not that great, so the battery won't heat up from the charging itself. Using a standard wireless charger on my Edge, the phone barely gets warm, so I'm not worried about damaging the battery.
With a rapid wireless charger, though, the answer may be different. Samsung's rapid wireless charger puts out enough heat that Samsung put a fan in it. How much of that heat reaches the battery I don't know. But since it's a rapid charger, it's pushing more power into the battery, which WILL make it hotter than a slow charger. So just like a wired rapid charger, it probably does have some impact on battery life
tl;dr version: If you're using a standard (not rapid) wireless charger, don't worry about it. If you're using any kind of rapid charger, only use the rapid charge mode when you really need to.

That's my opinion too.
The fact is that I'm using a regular/slow wireless charger and my S7 Edge barely gets warm at charging. But even so, my battery must have a problem ( I'm waiting for Samsung report). If it proves that wireless charging it's worse for battery (and it's just one year old), I'll switch to the good old usb cable.
You could test it out for yourself with my app

I recommend to read this
:good:
They replaced my battery, now its much better.
For now, I'll try using only the provided charger and cable.
There are so many options.
Superfast charging I find amazing. Quick plugin and the phone is back up to about 80% battery in no time at all.
Fast is ok. Just a little slower.
Standard is slow, it just ticks over.
I also notice that it appears to stop charging when the battery is full. Although I've stopped leaving my phone plugged in overnight.
But, I read that superfast might damage the battery and that's why it defaults to off. It's not a quick switch to enable/disable, so it's a decision to have fast or superfast on.
Or is life too short to worry?

Even if super charging would make the battery loose efficiency over time, I don't think it will be a noticeable problem during first owners time with the phone. I will upgrade in less than 18 months and I think most ppl upgrade within 2 years.

Fast wireless charger most of the time, but I did buy a couple super fast wired chargers to scatter around when I'm in a time crunch

Super Fast wireless charging all day everyday. I haven't plugged a cable into a phone since 2018. Battery life is solid so I'm never in a rush to charge a phone. Wireless is quick enough. I love the convenience of just throwing it in the stand without having to find the cable and stick it into the port. Especially in a dark room.
I've not really used wireless charging. So you have 15w wireless pads around the house?
Super fast charge too.
With PPS and the PD standard, it changes its power according to of the actual battery level and temp (and certainly more parameters) to avoid harming it.
I plug in every night, overnight next to my bed. Not fast charging, just regular charge, because it's not needed.
If you don't need to fast charge every day, turn it off. Doing it regularly will degrade long term battery life by a small amount. Both by the method of charging, and by the heat created by fast charging, as heat is bad for the life of a battery.
But all in all, it's not terrible. Just charge it howver you want. It's not going to cause any terminal issues. Just charge it when and however you want to.
I have switched off both Superfast as well as fast charging. Not sure if that will have any impact positive or negative as my opinion is that Samsung didnt go with 40W, 60W so on and so forth charging not because it cant do it (If Oppo,Vivo, Xiaomi can then Samsung definitely can) but as a bigger company they probably wanted to act more responsibly so they must have ensured that their 25W charging has negligible effect on battery and thats why they went with it. Just my 2 cents.
