I just bought a Samsung fast wireless charger with the intent on using it to charge overnight. Not sure why I didn't just opt for the slower one if that's my main use, but anyway, I'm worried about battery life and health with fast charging all the time. As it stands now, I only use fast charge if I really need it and just charge it overnight in slow mode. Does this wireless charge still allow you to use the slow mode or is it always locked into fast charge?

Yes you can. I have the same charger and all you have to do is go under settings>battery and on the bottom you can turn off fast wireless charging!

Awesome, thanks!
You can also just use a USB wall adapter that is not fast charge compatible, and it will charge at a normal wireless charging rate.
I just got my charger in, but I don't have a setting for fast wireless charging under battery settings. Right now it's charging normally, but when I do want to enable fast charge I have no option. Did it move with the latest firmware updates?
EDIT: Never mind, I just went out to check on it and the option is visible and enabled. Weird.
You can reference the charging tests I conducted with all charging methods for the S7 Edge. Fast Wireless Charging does not generate that much heat, nor does using QC 2.0

The setting for wireless charging appears only after using the wireless charger once. Maybe you have to reboot after that.
Another option for activating fast wireless charging appears under Accessoires at the bottom of all settings.

Slow wireless charging generates more heat than fast wireless charging. I've done about a dozen tests with both and the results are very consistent. In the end fast wireless charging is better as is QC 2.0 if you look at the temperature curves I posted above.

Plug in the quick charge 2.0 charger, there is no sign if it is in quick charging or just normal charging? Is there any sign on the phone to show it is quick charging?

Unless something is built into the charger you don't. The Tenergy has an LED the is blue when charging a non-QC 2.0 device and turns green when a QC 2.0 device is charging. Other than something like that all you can do is look at a battery monitor app and check how fast the charge is.
Check the current reading in GSAM.

You don't. But you notice that it charges from anything <=75% to 80%+- quicker then a normal charger. Reverts to slower charge rate from 80%-100%.
Only true way of knowing is to purchase an inline amp\volt meter. I bought one off eBay for couple quid. It plugs in to USB socket and you plug the charging cable in to it.

First of all, the phone will heat up a fair bit while charging. Secondly, you can connect to your phone with ADB over WiFi (with help of an app from Play Store), grab logcat and look for messages from the 'quickcharge' service. If QC is working, they will say that the phone has successfully negotiated 9V charging current with the charger.
You can just time it or something like that...

Where is this current reading in GSAM (screenshot)? I have the app (pro version/add on for rooted), and while it appears that one of my chargers is 2.0 compliant (based on rate of change on a graph)...I can't find where it shows the current/voltage option/graph mentioned above.
TIA.
Just post a screenshot GSAM whilst it's charging.

please help me
I can't find fast charging on/off on my N5 sm-n9208.
accessories features setting also lost on setting .
user manual guide include accessories features but my N5 lost
I think there is no option for enabling/disabling fast charging in Note5. You are forced to use fast charging.

hi ,
yes , i agree with @TAEL post above
i also found no option to "change " fast charging ...but ........
I had a experience where my fast charging just stopped "?"
I took/swopped my cable/ power cord with my old Note4 cable and fast charging was back again ! Also you can change charger plugs around ( eg Adaptive fast charging and a plain Samsung charger plug )
I thought about issue and came to a conclusion ,that surely consistent fast charging, cannot be good for battery and may shorten battery life ???? I now alternate with my 2 x Samsung cables/plugs .If i want fast charging i use my Note 4 cable/plugs (working ), vice versa.
If i want normal charging i use the other cable /plug .
Yes, i know these are a work around,
but surely, it's better than having no option in Note 5 battery settings ,regarding fast charging ??
good luck
As said, N5 no longer has the option to disable fast charging (cable). It does however have the option to disable fast charging for wireless charging. The option will appear once you use a fast wireless charger.
after I test with wireless fast changer I reply
thz
If you don't want to use Fast Charging.... don't use a Fast Charger.... simple. There's no option to disable it, but if you're not using a fast charger, then it won't fast charge.
Why My phone takes too long to charge.
You can find the option to fast/normal charge in the battery section.
Some kernels come with USB fast charging as an option that you can toggle. If you use this, does it shorten the battery health long-term ? I'm not referring to turbo chargers (aftermarket), this is just the kernel setting. I recall reading this awhile ago, but I was curious myself.

all it does is increase the voltage coming in when charging via a USB. USB charging voltage is about a quarter/third that of a wall charger. no, no negative affects.
Not at all, even with USB fast charge on it will draw less power than if it were plugged in a regular wall charger or the turbo charger. There's an app called Ampere you can use to monitor how much power the phone draws while charging (or even discharging) you can use it to see the differences between regular usb, fast charge usb, turbo charge, etc.
Ok, that's good to know. Now I can re-toggle the feature and not worry.:good:
What about if it is toggled on and you put it on a regular charger ? Is it still fine ?

if its on and you charge it in a wall outlet, nothing will happen. it will only work on a real USB connection.
Motorola put in support for the Qualcomm rapid charge in the nexus 6.
Read up:
https://www.qualcomm.com/products/snapdragon/quick-charge
It allows the battery to charge at a higher voltage with USB connections and Qualcomm certified rapid chargers AND a compatible cable. The nexus 6 can still recharge with standard chargers and cables, just at a slower rate regardless of kernel support.
To answer the damage questions: Moto says no damage to the battery as long as certified chargers are used.
Can't you use any standard usb charging cable? (Assuming it's not really long or poor quality)
Ok I have these 2 fast wireless chargers that worked previously before updates. They are not Samsung and have their own power supply. They did fast charger fine but now with the update it seems fast wireless charging is hidden under an acessories menu under advanced features. Well on my Galaxy s8 plus from T-Mobile.. there is no acessories menu.
So I can't enable it.. and it seems these chargers are not making it appear.. and again I swear they are capable of of charging this phone.
So I need some back door method of enabling fast wireless charging or the acessories menu. Perhaps through adb.
Anyone got any ideas?
I have S8+ with tmobile and its there.
Maybe do I wipe possibly?
But yeah it's in accessories and mine is enabled. Sounds like a faulty update?
And my wireless charger is fast charging but not as fast as wired fast charging.

Yea I think that for some reason the 3rd party wireless charger is not kicking in the option after this update. As before it was already enabled and working fine. I know the charger does indeed fast wireless charge this phone as it has all the standards and has done so in the past.. probably the only way for me to get around this is to use someone else's official Samsung fast charger to enable the accessories setting
Hi, I have a question.. I bought Samsung wireless charger 9w and I charged the phone completely switched off and the charging time was approximately 4 hours.. Is it normal? Maybe the wireless charging not working in fast mode if the phone is powered of?? Thanks..
9w is really low power to charge a 5000mah battery sooner than that
of course its normal with a 9w charger ... thats damn slow
Another question, is it bad for the battery on the long run?
I usually charge overnight during sleep so I don't mind slow charging just curious about battery life. Thanks
Qi standard allows one to use even lower charging power than that 9W for safer overnight charging. Check the alignment of the charging coils for optimal result.
9W is not fast wireless charging, it is normal; 15W is fast wireless charging.
