[Shield Tablet Q&A, Help & Troubleshooting] 2kool2Bcruel:
Sorry if this answered somewhere but, I'm getting really confused these days between what is for the ORIGINAL and what is for K1.

I found this the thread titled [UNOFFICIAL][Guide] Update Original Shield Tablet to Android M (6.0)

And this says ORIGINAL in the title but in the steps there is the section called Optional Stylus Support which throws me off because the ORIGINAL Shield has a stylus and the K1 doesn't but I know there have been some mods for the K1 regarding some mods to the back shell because the area for the stylus is still there on the inside etc.

So I am just trying to find the suggested method, if one exists, to update from 5.1.1 to 6.0. I assume flashing the full OTA update through TWRP wont work since there is a change in the bootloader. And then finding a TWRP that works with the new bootloader.
[Shield Tablet Q&A, Help & Troubleshooting] satan89:
Flashing stock recovery, and then updating via OTA should work afaik. But OTA updates the bootloader, so you'll need a different twrp for it after that.
[Shield Tablet Q&A, Help & Troubleshooting] w0rtez:
I was going to ask almost the same thing before i came to this thread, if im rooted, could i just flash the new custom recovery TWRP-3.0 then flash MM 4.0 OTA and then SuperSU, doing all that from the recovery itself?
[Nexus 6P Q&A, Help & Troubleshooting] treIII:
Can someone with true knowledge let me know which position the radio is in on the Nexus 6p? I'm trying to figure it how to make a flashable zip for the radio.imgs available for the 6p to flash in twrp recovery. Thanks
[Nexus 6P Q&A, Help & Troubleshooting] Pain-N-Panic:
Not entirely sure of what you're asking. However, I believe TWRP 3.0 is able to flash the angler radio image file itself directly. Someone may correct me if I am wrong as there are only a select few .img files it is able to flash. You can check TWRP's website/forum for their changelog, should be listed in there.
[Nexus 6P Q&A, Help & Troubleshooting] galaxys:
No, you can not flash the Radio or Bootloader img in twrp 3.0. You can for others like kernel & vendor...

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] MinerBoy004:
Hello. I currently have a unlocked bootloader Kindle Fire HDX 7" with Cyanogenmod 11. I been looking into all that "hardware" stuff, and I was wondering if there is a way to overclock this device. I did seen some weird Cyanogenmod 11 kernel, but I'm not sure if that works. And if it doesn't, what can I do to overclock it then?

Thanks.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
You can't without a different kernel. All the custom roms for this device use the same kernel with possible exception to CM13 (believe that still uses v4 kernel) .

Given observed thermals with all cores maxed out you probably wouldn't have much head room of unlocked. Big jump in SoC temps stepping through upper frequencies; geometric curve.
[Samsung Galaxy S7 Questions and Answers] shingz96:
Asking about which s7 is with Snapdragon 820 and which version is Exynous 8890.

And also anyone know which is the best suit snapdragon or exynous one?:D:D Willing to know
[Samsung Galaxy S7 Questions and Answers] Nequs:
There is already a thread comparing the Exynos 8890 with the Snapdragon 820 over here:

http://xdaforums.com/galaxy-s7/how-to/exynos-vs-snapdragon-benchmarks-t3319913

But to summarize it a little bit:

The general consensus seems to be that the Exynos 8890 has the fastest processor, while the Snapdragon 820 has the best performing graphics processor. Notably, the Exynos chip seems to be faster at single threaded as well as multithreaded workloads due to the high single/dual core frequency of 2.6 GHz, and it's total of 8 processing cores.

Some people are concerned about the power consumption of the Snapdragon 820, and believe the Exynos 8890 to be the more power efficient choice.

There have been some concerns about the cell reception on the Exynos 8890 version, leading some people to consider ordering the Snapdragon 820 version.

The last two points in particular should be taken with a pinch of salt until more people get their hands on the phones and conduct some proper tests.
[Samsung Galaxy S7 Guides, News, & Discussion] sonhy:
very good stuff!

maybe you could also record the heat at the hottest spot of the phone during charging? I think qc3 has the same charge rate but its able to change voltage to reduce creating waste heat compared to qc2.0.

my main concern with the s7 is the battery life, i know it won't last me a full 18hr day so i really need a portable fast qc2 charger that is pocketable, so maybe 5000mah, but have not seen such a small qc charger tho
[Samsung Galaxy S7 Guides, News, & Discussion] CLARiiON:
Excellent post and well-made graphs. Thanks for your efforts.
[Samsung Galaxy S7 Guides, News, & Discussion] ISperfection:
well done. good info here.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
I don't have a thermal camera, or way to do that otherwise I gladly would. I can recommend a small 6000mah external battery pack if you want; Ill do a quick write up too (if you need one). The Samsung charger stayed at 9V the whole time per my multimeter's reading it just dropped go .5A near the end.

Thank you, I will add in a standard wireless charger test (since my free Samsung one is enroute), and I can also get their fast charger too. I believe Samsung's fast wireless charger is only 7W so it would be slower than the Choetech one but it never hurts to see how fast it is.
[Samsung Galaxy S7 Guides, News, & Discussion] sonhy:
[MENTION=5581268]Pilz[/MENTION] yes pls let me know of a qc2.0 small portable charger :) I think a quick 30mins charge to add 50% battery life mid day will be the best ease-of-use solution for me.

with the heat measurement, I'll be happy with your commercial grade temperature sensor that the great designer created for you, your fingers :p or better yet, the inside of your wrist.

preferably touching the same area on the phone every time and grading something like 1-5 hot/comfort levels maybe? just suggesting, no pressure :)
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
I'll look into some methods to measure the heat easily while they're charging. I'm conducting the standard wireless charger test using my free Samsung wireless charger right now :) QC 2.0 chargers the fastest when you start at a very low battery percentage, so ideally you can achieve the results posted, but ambient temperature, starting % etc contribute to whether or not that's attainable. It's still a good estimate for 30 minutes of charging +/- 5% for other factors. The phone also chargers slower when the screen is in. The rate would go from 9V/1.67A to 9V/1.10A with the screen on. It was very consistent when I turned the screen on and off during the test.
[Samsung Galaxy S7 Guides, News, & Discussion] sonhy:
i actually won't care about heat issues while charging this time round, it'll be like my moto defy, i just run it under cold water after a fast hot charge, wont be using the s7 for many years so not worried about moisture build up.

i have ordered a magnet micro usb cable that says its rated for 2.4A charging so hopefully it'll allow easy qc2.0 charging, no need to plug in, it magnetically snaps on and off.

i think the best charge setup would be a 30mins quick charge (magnet) on the office desk than a 60mins wireless qi charge, carried in your pocket type situation.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Did you by chance order the Znaps? I backed them ages ago for both the Type-C and micro USB connectors. If I'm lucky I might eventually maybe sometime before I die receive them. I don't expect much from a kickstarter campaign that's been delayed this much. I'm finishing up the standard Qi/PMA charging test. It shouldn't matter the standard it's using but if it's important the Samsung wireless charger is actually PMA.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
OP Updated

-Standard wireless charging test added

-All figures updated to reflect the new test
[Samsung Galaxy S7 Guides, News, & Discussion] sonhy:
no, its from aliexpress, $10 or so, ive seen cheaper so I would say the poor Kickstarters had their designs stolen and made cheaper... im not sure, i just buy what's available and easy. just search magnet usb cable, you'll find heaps, the more exy ones claim 2.4A current rating.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Let me know how it works, I rarely use cables to charge my phone becusse I hate micro USB ports plus I'm used to the type C on Nexus.
[Samsung Galaxy S7 Guides, News, & Discussion] peachpuff:
Have you tried charging with 18w charger(not wireless) rather than the samsung one?
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Yes it doesn't matter becuase the phone is only rated for 15.03W so it can't use more than that no matter the charging method. See screenshot below:
[Samsung Galaxy S7 Guides, News, & Discussion] sonhy:
[MENTION=5581268]Pilz[/MENTION] yeah sure, it should arrive in a couple of weeks. i hate plugging in as well, even with the usb type c, its reversible but finding the port isn't always easy, they should have made the port surface like a cone or funnel so your guided into the port more easily.

the use of the magnet is awesome, Sony's external side charging pins have been around for ages, its really the charging current and quality of the copper that im worried about.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
I just wish they had Type-C because its so much better especially after using it for a while now.
[Samsung Galaxy S7 Guides, News, & Discussion] xxaarraa:
I never knew that plugging in a micro USB cable was so difficult. It could be one of those things that once you try a better alternative (type c maybe?) makes you ask how you lived without it, but I don't see what the fuss is about just yet.

I've used wireless chargers for years (way back in the NExus 5 days even) including in the car. Any word on fast wireless charging and heat? I'm worried about it pumping a ton of heat on to the back of the phone especially for extended periods such as overnight.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Micro USB is just more of a hassle becusse usually you need to angle it while inserting it into the phone. Type-C is nice becuase there no worrying about how I need to orient a cable when I'm half awake plugging my phone in. It's hard to understand why its nice until you use it everyday.

I haven't been able to measure the heat yet, but the phone is cooler using the 10W wireless fast charger than it is using QC 2.0. The phone isn't hot to the touch but it is warm using the fast wireless charger. I'll try to download a battery monitoring app that measures battery temp while it's charging. This method won't be as accurate as physically measuring it, but it should still give a good indication of the temperature.

Edit: I tested the temperature using GSAM battery montior via the fast wireless charger fro ~6% charge (28-34%) and the temperature rose 6 [F], the I let the phone cool and tested QC 2.0. The phone was charger for 6% to keep things cosnistent with a temperature change of 5[F]. I would need to find a way to more accurately measure these values because that quick test doesn't really mean anything at this point.
[Samsung Galaxy S7 Guides, News, & Discussion] ahrion:
Does the Adaptive Fast charging by Samsung with with QC 2.0 compatible devices or is it only exclusive to Samsung?
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
It's just a QC 2.0 charger from what I can tell. I have a battery pack that will charge using QC 2.0 so I can test it using my multimeter
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
It is the same thing as QC 2.0. I used the Samsung charger to charge a battery pack which takes QC 2.0 and it was putting out 9V so that means its a QC 2.0 charger and Samsung is just branding it differently.
[Samsung Galaxy S7 Guides, News, & Discussion] Eyalbc:
Hi, great work.

did you see the KMASHI Fast Wireless Charger ,Wireless Charging Pad for Galaxy S7,Galaxy S7 Edge, Galaxy Note 5,Galaxy S6 Plus, S6 Edge+ and other QI Enabled Devices - on AMAZON it say it is 15W and it is $21.
[Samsung Galaxy S7 Guides, News, & Discussion] peachpuff:
I doubt 15w output is possible with current chargers, there's a lot of efficiency loss with these wireless chargers so to get 15w output with them you'd need around 20-25w on the input side. So far qc3.0 can only do 18watts.

Maybe pilz can measure the input wattage with that usb tool and use the ampere app to measure the readings on the phone to see the efficiency loss. I'm seeing 50% loss with those ebay wireless chargers. Around 1.3a on the input and 700mah on the phone.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
I have measured the input voltage for each charger via my multimeter. The Samsung standard one is usually 5V/1.2A, Samsung wall charger 9.1V/1.67A (fluctuates), standard wall charger: 5V/1.6-1.8A, and finally the fast wireless charger 9V/1.8A. All of these change depending on a variety of things,but I wouldn't mind taking pictures to show each oens output.
[Samsung Galaxy S7 Guides, News, & Discussion] peachpuff:
That's 16watts, what does ampere say when your charging the phone at that rate? https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en

I wonder if the ampere reading is at 5v or at the battery voltage, normally around 3.9v.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Ampere isn't accurate so I don't use it. I use a multimeter directly plugged into the USB charger and cable. I'll double check the voltages on the fast charger for you but the phone isn't getting 18W ifs getting 8-9W
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Here's what my multimeter is reading (which seems more like what's going into the phone from the wireless chargers but I could very well be wrong). If you really want ill use Ampere but its not as accurate because the current drops when the screen is one significantly which I can demonstrate in a video if you would like. See attached images for the voltages

The phone started at 57% battery for reference so the rates will be higher when the battery is below 40%. This is just to give you an idea of whats going on.

Choetech 10W wireless fast charger: 9.34V/1.33A (12.44W)

Samsung standard wireless charger: 5.27V/1.23A (6.48W)

Tronsmart QC 3.0 charger (still works with QC 2.0 devices): 9.20V/.96A (8.83W)
[Samsung Galaxy S7 Guides, News, & Discussion] peachpuff:
Just try ampere for a bit, 12w is being sent to the charger, but how much is the phone receiving wirelessly?
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Okay, but the current drops from 12w to ~7W the instant the screen turns on like clockwork
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Here it is fast wirelessly charging with my little multimeter next to it. The 10W Choetech fastbwirelws charger is plugged into my QC 2.0 Aukey power bank for reference. The Ampere readings kept jumping around from 10mAh to 1500mAh
[Samsung Galaxy S7 Guides, News, & Discussion] Eyalbc:
so any verdict on the KMASHI Fast Wireless Charger?

anybody own one?
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
No, but judging by the number of fake Amazon reviews I would avoid it.

[Samsung Galaxy S7 Guides, News, & Discussion] sweets55:
Nice graph. I read the thread but it's early so might need to read it again. I have two non fast chargers (Samsung and Choetech Iron Stand). I have two Choetech fast chargers T518 and T511-S. Yes I like wireless charging. LoL When I pull down the drop bar when the phone is wirelessly charging the charge time to fully charge the battery is about same. The fast chargers say fast charging on the display. What cable to I need to get for the fast chargers to charge faster? The one 2.0 fast charger to the right with the black dot doesn't even work with the Choetech fast chargers but does with the Samsung. I got them mixed up but think that might be the one that came with my S7E. The other two are S6E and Note 5. As far as heat I used just the wall charger once for 20 mins and it was warm. I charge my phone overnight on the wireless Choetech stand and never noticed it being warm. Not that I really care since I never keep a phone that long. Damn T-Mobile/Jump.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
The phone charges at about 33-50% slower when the display is on. I can take a short video clip to show you how the instant the display turns on, the current drops off. This only happens on the S7/S7E and not either one of my Nexus 6P's.

The Choetech 10W fast charger needs an 18W power supply (QC 2.0 or 3.0), so the stock Samsung 15.03W one will not work properly with it. Choetech contacted me to say they're working on a newer version that will work with Samsung's stock adapter for fast charging. I will let you know when I receive it to review.

The Samsung Fast Wireless Charger does fast charge with their stock adapter (the adaptive fast charging one) which is why it has a lower output than the Choetech charger (slower charging). I use a 18W Tronsmart/30W Power Partners chargers, or one of my multiport QC 2.0 (18W each port) charging hubs to power the fast wireless chargers. If you try a 18W charger it should work at it's full speeds for you.
[Samsung Galaxy S7 Guides, News, & Discussion] sweets55:
Oh are you referring to having the always on the display I don't use that. I never leave leave the screen on while charging well I might just turn it on for a second to check notification. Ok I think I understand now. Thanks for the fast reply. hehe
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
AOD doesn't affect the rate form what I've noticed, I'm talking about physically turning on the display. No problem, let me know if you have any questions.
[Samsung Galaxy S7 Guides, News, & Discussion] sweets55:
Damn already ran out of thanks. I'll get ya tomorrow. :good:
[Samsung Galaxy S7 Guides, News, & Discussion] darkphantom:
Okay, so if I have the wireless charger that doesn't say fast charge, it is the standard one? it shows 5V @ 2Amps on the bottom. I tried with my S7 Edge....very slow charging compared to wired.
[Samsung Galaxy S7 Guides, News, & Discussion] peachpuff:
That's the 5watt charger, the fast charge one outputs 10watts.
[Samsung Galaxy S7 Guides, News, & Discussion] darkphantom:
The actual charger that connects to the wall has 9v [MENTION=1247388]1.6[/MENTION]7a
[Samsung Galaxy S7 Guides, News, & Discussion] sweets55:
So let me get this straight. To get fast charger to work like it should (Fast) I need a 18w power supply which is not a standard Samsung fast charger for any of the past phones like the S6 or Note 5 correct?
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Not a problem!

Does it have a fan on it or say "fast charger" ? If it doesn't then it's the standard 5W wireless charger. The input on the bottom will say 5V/2A, but don't forget how inefficient wireless charging is. The real output is more on the line of 5W.

No, the fast charger outputs ~7.5W. The Choetech one I tested is actually 10W (it needs a 18W input vs 15.03W for the Samsung fast wireless charger). Look at the total charging time for both of those fast wireless chargers. The Samsung is still slower despite having a cooling fan built into it which allows it to charge faster long. The Choetech 10W beats it by ~11 minutes becasue it has a higher output; the Choetech also will NOT work with the stock Samsung adapter, you need a 18W QC 2.0/3.0 one to get the max speeds out of it.

The Samsung Adaptive Fast charger that comes with the phone has 2 outputs: 5V/2A (10W) and 9V/1.67A (15.03W) which is the maximum rate the phone can charge with a physical cable. The phone can charge at 15W via a wireless charger once a true 15W one is released (like the Incipio one). I can take pictures of each charger, its rated input, and my wall adapters that were used to conduct the test if that would help out. Once a 15W wireless charger is released I will get one to test.
[Samsung Galaxy S7 Guides, News, & Discussion] peachpuff:
What if you try the 18w charger with the samsung wireless fast charge?
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
That won't make a difference because that charger can only take a maximum input of 9V/1.67A just like the phone. I can plug my S7E into my 30W PowerParnters QC 2.0 charger, but it will only charge at a maximum of 9V/1.67A that it's rated for.

Edit: to be clear I'm referring to Samsung's Wireless Fast Charger NOT their standard wireless charger. The above still applies to both, except the standard wireless charger will only take a max of 5V/2A and output ~5V/1A
[Samsung Galaxy S7 Guides, News, & Discussion] peachpuff:
Ah ok, so it looks like the cheotech is the only one that does 10watts so far.

That's quiet the efficiency loss, 15w input to 7.5w output.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
That's correct, and the charging data seems to support that. Samsung never stated the output of their chargers, but it can be assumed from their speeds if you do the math. There is a lot of power lost to head while charging wirelessly especially with a thicker case which adds 'resistance' by increasing the separation distance between the coils.

OP Updated:

-Figures simplified for wireless/wired

-Added pictures of each charger
[Samsung Galaxy S7 Guides, News, & Discussion] sweets55:
Pilz - So this is the Choetech charger that I need for the S7E in order to get fast charging to actually fast charger correct?

http://www.choetech.com/choetech-c4003-adaptive-fast-charging-quick-charge-2-0-charger/
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
Yes, that one should work fine with their 10W fast wireless charger. Any 18W QC 2.0/3.0 wall charger will work just fine.
[Samsung Galaxy S7 Guides, News, & Discussion] Pilz:
I'm going to use a QC 3.0 charger and add it to the test to prove it shouldn't change the charging time vs QC 2.0 since the phone doesn't Southport support QC 3.0

Very good data.

I am curious to know tho.

I noticed with my Note 5 .

When charging with a slow charger my phone battery lasts longer as apposed to charging it with a fast charger.

I haven't tried slow charging on my S7 edge as yet.

Would like to know if slow charging actually helps the battery last longer in a way ?
