Nice that you are finishing the results. Follow up on my previous case. I have bought a USB digital multimeter that looks like this. I have studied the power trend requested by the fast wireless stand. Initially, when the S7E is placed on the stand, the power requested by the stand is ~9 V and ~1.4 A which means ~14.4 W is drawn by the stand. The power goes down from that value to around ~9V and ~1A (=~9W) and goes up again to maximum of 14.4 W periodically for ~15 mins. However, after the initial 15 mins, the power drawn by the stand starts to drop to ~9 V and ~0.7 A (=~6.5 W) in a few seconds and stays at that level for the remaining amount of time, unless you switch on the phone and interact with it for few seconds and let it idle and turn off the screen which causes the power draw to increase up to a max. of 14.4 W for few seconds before settling at ~9 V and ~0.7 A (=~6.5 W) again until you interact with the phone again (obviously that when the screen is on the power drawn by the stand is even lower). After 15 mins, the phone has charged up ~8 % of juice (note that the conversion efficiency of the stand is up to 80% as advertised by Samsung).

From my calculation, say an average of 6.45 W of power goes into the stand while the phone is left idle on the stand without interacting with it, and the battery capacity of the S7 Edge is 13.85 WHr, this translates to about ~130 minutes to charge the from 0 - 100 % but this obviously is not the case as the efficiency of the stand is only 80% and the phone itself is also consuming some amount of energy while it is charging for the background task like push notifications. From my experience, the battery temperature never goes beyond 37 degree Celsius while fast charging wirelessly. Hence, I am still not sure why my S7 Edge still take that long to charge like 25 % per hour.

Nice observation there mate! Gonna take care of my fast adaptive charger hehe!
[Samsung Galaxy S7 Guides, News, & Discussion] aazznn92:
Hi all, I think you can disregard what I said above. As I have discovered that the fast wireless charging speed depends significantly on the ambient, surface and battery temperature. I tried using a USB fan blowing towards the wireless stand while the phone is charging and I got a much improved charging speed. From 3-95%, it only took 121 minutes and the battery temperature does not go beyond 33 degree Celsius.

[Samsung Galaxy S7 Guides, News, & Discussion] hp79:
I appreciate your work. One thing I don't get is how is it that Fast wireless charging produce less heat than the regular wireless charging?

The efficiency should be similar, so the energy loss would be greater in the same time unit which means more heat. Or does raising the voltage to 9V (from QC 2.0) raise the efficiency that much? Or maybe your Qi Fast charger has a fan or better air flow than the slow wireless charger?

Also, I wonder how is it that wireless charging is even cooler than the wired QC2.0. Does that mean QC2.0 wastes even more power than the already inefficient wireless charging method?

One explanation I could think of is that the total energy waste is indeed higher for wireless charging, however since it takes much longer time it doesn't get as hot as QC 2.0 wired charging... but this is just my thought.

Whatever the case is, I noticed way more heat from using any mode of wireless charging than the regular cable charging. In my experience without any measuring equipment, if I rate the heat from 1-10, 10 being the hottest, I would rate it like this:

USB cable 5V @ 1-1.6A (1: luke warm, below 35C)

USB cable 9V @ 1.6A (6: hot, close to 40C) - this is QC2.0

Wireless 5V standard (8: concerning hot, over 40C)

Wireless 9V Fast charge (8: concerning hot, over 40C)

I mostly use QC2.0 charging. When I do a QC2.0 charge or wireless charge I either have a fan or the office is chilly enough to keep the temperature around 2-4 out of 10 scale (near or below 35C).

I have circular Choetech Fast wireless charger, Nokia D900 normal wireless charger, and several QC2.0 chargers.

[Samsung Galaxy S7 Guides, News, & Discussion] rokish:
thanks Pilz for helpful post

just got a s7e and looking for some charger, so any recommend for differents charger?

1. Best fast wireless charge: still Choetech 3coil?

2. any recommend for portable charger? i need capacity around 10.000mah with QC 2.0 and 02 output port. anker powercore+ expensive but have only 01 port

3. car charger with QC 2.0: i see aukey dual port QC2.0 with 11.99$ is the best price for value?https://www.amazon.com/Quick-Charge...&redirect=true&ref_=oh_aui_detailpage_o01_s00

thanks for help.

---------- Post added at 04:00 PM ---------- Previous post was at 03:48 PM ----------

1 more question: i see s7e now don't support QC 3.0 but if we still use 3.0 charger is there any affect to the phone?

if not i'm thinking about buy a QC 3.0 charger so that i can use it for the next phone that support QC3.0 (or in the future s7e can activate s820 to use QC3.0 :D )

I have attached some thermal images I just took. You (OP) may download and upload them to your own image host/site if you would like to add them to the original post. I will also keep them uploaded to imgur but I don't know if they delete after so long, that's why I say do what you wish to keep them up and available.

Both sets (with/without case) were charged for 30 minutes each with the internal temperature in my house being 78°F and only a ceiling fan creating a small breeze in the room.

Both sets had fast wireless charging enabled and charged via fast wireless charging (I checked just in case it was only charging at normal speeds).

I used the official Samsung Fast Charge Wireless Charging Stand for the tests.

[Samsung Galaxy S7 Guides, News, & Discussion] travissand:
Thank you thank you for a thread with real data. It's so hard to find real information these days. I stumbled on your thread when trying to find out if my phone was capable of using the full Qualcomm 2.0 specs. In other words was it capable of the 12 volt input? The answer is found in this thread. No the answer is no. It's only taking in 9 volts. I'm so glad for all your work you put into the graphs so that we can understand what is actually happening with these different Chargers. That way we can make good decisions about which Chargers to buy four our needs.

I'm done so much testing of my own messing around with watt, volt and amp meeters. checking cheap cord to expensive chords standard chargers qualcomm 1. Chargers 2.0... I know firsthand what you've done for us was very very time consuming.

It's frustrating the phone companies are milking everything just like any Corporation does. Fast charging Is Not A New Concept. My RC car has been fast charging for many many years. It's 22.8 volt battery pack 4000 milliamp hours . And it charges in 24 minutes without getting warm. My freaking toothbrush has been charging wirelessly for 10 years come on Samsung get with it.

I feel like taking one of my high current connectors from my RC hobby stash and soldering it into my phone so I can bypass its own charging mechanism and pump some real current in that baby. Trying to mix hi current with delicate data cables is a joke.

There should be two ports a dedicated one for charging and the other with a removable waterproof rubber plug for data. The charging port should have 2 large round metal pads that detach with a seal around so you can replace it if it gets corroded and gunked up. That's what they should have done in the beginning it's all irrelevant now. With wireless charging you can leave the waterproof plug protecting USB port with the faster Wi-Fi you can access your phone without the data cable. Now if I could only find someone that's invented the perfect case. A case that has a kickstand which works both portrait and landscape and attaches to the Quality OtterBox belt clip. Has an extended battery built-in wireless charging and a metal saucer for the magnetic ball stand in the car. Heck why not throw in a 10-watt LED just for the heck of it. Okay one more thing a projector. And the kitchen sink. Sorry for my rant but back on topic here which was thank you.
[Sprint Samsung Galaxy S6 Edge] Dandroi:
Hi, i just bought a sprint s6 edge phone and I had to configure the apn in order to get 3g connection in Mexico with Telcel.

So what I'm trying to ask is that if I change the csc code from spr to tce then i would get the rom according my region and therefore 4g connection?

If this doesn't work, could I brick my phone?

Currentlu my phone is running renegade rom, and it's rooted.

Regards
[Sprint Samsung Galaxy S6 Edge] mkalter:
You won't get 4g and it won't brick your phone. It'll only reset it back to factory settings but it will not unlock other frequencies then the current ones.
[Sprint Samsung Galaxy S6 Edge] rickballs:
call sprint and get your msl code, go into ##data#, edit and turn on the bands for mexico. saludos y arriba las chivas
[Sprint Samsung Galaxy S6 Edge] mike0212:
It should work

I have my Sprint S6 Edge connected to MetroPCS and I am receiving LTE. When I was in Mexico I got my same phone connect to Telcel and my 4GLTE was working also. Just go in to the APN settings and where it says bearer, put it to LTE. It takes a while to connect but it will connect. As far as I know you only need the MSL if you want to send and receive pictures on 4GLte since you will need to edit the MMSC URL from there. Also once you change the APN settings make sure the network mode switched to automatic. In my experience Changing the sales code bricked my phone by saying "unfortunately, system ui has stopped" forcing me to go back to my stock rom.

[Samsung Gear 2] slapshot2286:
Ok so I have used the camera manager on the Gear 2 to take photos using the phone's camera while viewing on the watch. Is anyone familiar with possibly reversing this function so we could see the Gear 2's camera on the phone and take pictures through it? Its difficult to near impossible to take a photo if you're holding the phone at the same time, but if you were to be able to use the phone to view the Gear's camera, you could just point your wrist and use the phone to snap the photo. Anyone have any ideas on this?

Thanks!

i expected as much based on the geekbench scores :) thus far, the s7 edge top multi score is only 2.5% above the top mate 8 score, so yeah, in everyday operation they should be operating exactly on par!

very nice comparison video indeed, what i find intereeting is the insanely high contrast of the s7 edge display, compared to that the mate 8 display looks almost washed out *lol* and thats crazy considering how brilliant it actually already is imho! :)

Just returned my s7 edge. Screen was too small and the curved edges have an annoying blue hue when looking at it from the front. Battery was really bad in comparison to my mate 8 so gonna stick with this beauty. Camera was very very good though.

The gear vr was really good but just not enough to warrant keeping it.

[Mate 8 General] bricky23:
I have had this phone for about 24 hrs. But so far it is the best phone I have ever used! It's what the nexus 6P should have been. Nothing slows it down. And the battery is insane. I have been using quite a few phones that don't have an app drawer. So I even like and am using the stock launcher. I downloaded the stuff needed to unlock and flash a rom. But I think I will just use it stock. Great phone!
[Mate 8 General] CloudCompute:
In the video, the blacks on the S7 edge look really deep and on Mate 8 it's just ok, which was expected as S7 Edge has an amoled dosplay. However the whites on the S7 Edge look also much more clearer brighter and accurate compared to Mate 8, which isn't white enough. And colours and contrast overall look much better on the S7 Edge. I want to buy a Mate 8, I hope the difference in the display quality isn't as pronounced as it seems in the video. For me a gorgeous display is just as much or more important that the speed and performance.

I am looking for feedback from folks that have held both the devices up close.
[Mate 8 General] manook:
I've owned both and trust me the s7 edge just can't compete. The screen on the edge is nothing special. The edge itself causes a blue/green hue down either side and made me feel nauseas. Its ALOT smaller, it felt tiny in comparison.

I have never stuck to an older phone when new stuff comes out. That was until I've had a mate 8. The battery life on this is much much better than anything else I've used.
[Mate 8 General] sobelixtus:
I currently have both S7 Edge and Mate 8.

S7 Edge has much better camera than Mate, but that's really it. Everything else is better in Mate. Battery life and overall usage are much better in Mate. My honest opinion.
[Mate 8 General] jbmc83:
thats what i said in my post ;) not worried at all, just thought that was noteworthy
[Mate 8 General] CloudCompute:
Thank you manook and sobelixtus. I have one more question though. I have a Mate 7, and am pretty happy with it. Is the display on the Mate 8 significantly superior to the one on Mate 7? I guess it is, because the display on Samsung Note 5 is so much more punchier compared to the Mate 7, and I see comments here indicating Mate 8 display is just as good if not better compared to the Note 5.
[Mate 8 General] Polonius:
I had s7 edge for a few days and decided to sell it.

S7 edge (820) version still lags, both gaming and ui. And battery life is just average. Mate 8, on the other hand, is a fast, smooth, long living beast . I don't ever regret selling my S7 edge for Mate 8.
[Mate 8 General] rowihel2012:
samsung problem

not the sd820

touchwiz is crap
[Mate 8 General] dannejanne:
I have both the Mate 8 and S7 Edge (Exynos) at the moment. However my S7 Edge will most likely be returned.

Benchmarks is one thing. Real world usage another. My Mate 8 flies compared to the S7. Mate 8 is much more responsive and faster in general operation. Samsung still has its lag from time to time and generally is hesitates a lot more when doing things. Delay on things that Mate 8 does not have. Also the S7 lags in games even Monument Valley while they run perfectly smooth on my Mate 8.

You can't tell the S7 Edge has so good specs because it's bogged down with bad software.
[Mate 8 General] themissionimpossible:
However... observed Samsung S7 lags and delays might be partially due to its display resolution which is QHD (1440x2560 pixels) compared to Mate 8 FHD (1920x1080 pixels).

So the S7 GPU is moving/drawing 3,686,400 vs. 2,073,600 pixels, almost twice than the Mate 8 GPU.

Essentially, the point is if the QHD resolution is something worth to have or not...
[Mate 8 General] dondavis007:
Shouldn't matter, it's 4 gpu cores on the mate against 16 on the S7. It's just the way lagsung is. I've had quite a few and even if TW it's way better nowadays it's still not very optimized. Nothing can compete with stock Android/AOSP but some oem layers are just better than others. I'm my opinion HTC is best on optimization.

For this reason I've never used Touchwiz in my Samsung ex-smartphones (starting with the Galaxy S2), but always installed Nova Launcher...;)
[Mate 8 General] dannejanne:
The camera on the S7 Edge is not always better than the one in our Mate 8's. I have both phones and did some comparisons last night indoor when the sun had set. The Mate 8 beat it in every category. Both set to auto mode. To top things off the Mate 8 used double the ISO than the Samsung which results in more noise and blur. I downsized the Mate 8's photos to the same size as the Samsung. The S7 Edge has unnatural colors (strong yellow), less details and looks more compressed.

Also, the Mate 8 is much more responsive and fluid than the S7 Edge. There really is no contest. You can not tell the S7 Edge has those good specs because it's completely boggled by bad software. I get lag in most games with the Edge even Monument Valley. Totally smooth on my Mate 8.

Mate 8 (ISO 320), S7 Edge (ISO 160)

S7 Edge (ISO 400), Mate 8 (ISO 800)

[Mate 8 General] CloudCompute:
I saw an S6 edge+ yesterday in a retail outlet. I compared it to my Mate 7 side by side, and I have to admit there is no comparison. I was blown away. Be it the brightness, contrast, color saturation, or the paunchiness, S6 edge+ display is absolutely stunning, gorgeous. All other phones have comparable displays, but Samsung top line is a different league altogether. I guess it's because they have Super AMOLED displays.

Now, I ain't a Samsung fanboy, I've never owned a Samsung phone and wouldn't' buy one. What I am trying to find out from folks on this forum is, does the Mate 8 have a display that is as pretty as the S6 edge+ or is it more like my Mate 7. I don't have a way see one in retail stores in my country.
[Mate 8 General] dannejanne:
It' pretty close to the Mate 7 screen not very big difference.
[Mate 8 General] CloudCompute:
To me that's a little disappointing. Mate 7 display is great, in fact it's better than all other ips displays, however it's no match for the Super AMOLED display of the S6 edge+. I hope Mate S2 comes with a Super AMOLED display with above 700 nits brightness.
[Mate 8 General] dannejanne:
Don't get you hopes up too high. The Mate S had a Amoled display but a very bad one. Samsungs panels are in a league of their own and they always sell their older ones to other companies to have the upper hand in display quality. The one on my S7 Edge is amazing.

[Mate 8 General] bricky23:
If anyone has both. Try the game Ramboat from the play store. It was smooth as silk on the Mate 8. But I wanted a smaller phone, so I got the s7 edge. It is laggy, drops frames, jittery. Other games play very well, on the edge. And I am not a big gamer. But I do like playing that game. :(
[Mate 8 General] blackinfinity:
Well the story repeat itself. Samsung got good hardware with bad coded software they never take advantage of their superior hardware.
