[Q] Anyone using Qi charging?

I'm curious if anyone has been using Qi charging with their TabPro? Anyone's comments would be appreciated.
I used a micro-usb Qi coil receiver between my TabPro 8.4 and the Poetic case for a few weeks without issues.
But then something happened to cause the Qi charging pad to overheat. I ended up having to have the TabPro 8.4 replaced by BestBuy as the TabPro would no longer charge at all, even trying different micro-usb cables and 2.1 amp power adaptors. What was even stranger, was the battery continued to drain even after powering the TabPro off! I'm puzzled as to what was damaged, but the end result was the battery went from 41% charge to 7% charge overnight even though it was powered off (not sleeping, but powered off) and not connected to a charger. When I discovered it was at 7% I removed my account info, but even with the charger plugged in, the battery went down to 3% while working on the TabPro. When I checked on it an hour latter it was dead. If I plugged in the charger, after about 20 seconds it would flash the green battery for about a second, then it would go out. No boot, no charging, even after leaving it charging for 24 hours.
So I'm very reluctant to try to use Qi wireless charging on my replacement tab. I suspect the Qi charging pad failed and overheated. There is a spot about the size of a dime where the plastic partially melted on the charging pad. The Poetic case and the TabPro look fine, and the charging pad still acts like it is working. Very puzzling. Any ideas or cautions?

The only thing I can think of is maybe the Qi charging pad failed to deliver 2.1 Amps to correctly charge it (I don't think they even make 1 Amp coils yet? - though I could be wrong.) , maybe the tab went into charging mode but it was really discharging since not enough current was going in that it needed to charge + keep the tablet running so in the end maybe it destroyed the battery since it went completely flat which is usually a bad thing for l-ion battery's
Usually when android says the battery is at 0% the battery really has about 20% remaining for protection of the battery and preventing it from going completely empty (l-ion can really be drained to 2.5v but android reads 0% around 3.4v or 3.2v if i remember correctly as protection from flat-lining the batt), however if it was under charging mode I'm sure it would override this as it thinks it's plugged in so it's not paying attention to the battery, but really the batt is draining to compensate for the underpowered charger, that would be my guess maybe constantly using the Qi charger the battery circuitry changed the battery status from lv 2 (good) to ~ lv 4 (bad) since it wasn't receiving the current it was supposed to and the circuitry thought something was wrong with the battery cells or the battery just went bad since it was always under a charging / discharging state never reaching 100%.
on a side note
I found this tablet to be very fussy when using other chargers then its official one, I have tried several chargers and they just dont function like the stock one for example
HP Touchpad charger 5.3v - 2.0A - Very high quality charger and even won some awards for beating out other chargers - I found this would sometimes not fully charge the tablet to 100% it would idle around 98% (I have two of these chargers) - Charge current starts around 1800 mAh drops to 200 mAh when battery gets full don't think its enough to top it off. (charges at 5v)
10,000 mAh Power-bank (5v , 2.0A), found out this would not fully charge the tablet either it would get to 80%, upon further inspection the 2A port was only delivering about 1 Amp of current according to my amp reader (voltage drop to 4.98)
Samsung official charger (5.3v 2.0A)- though seems to start at a pretty high 5.60 volts (higher then other chargers) , and charges at about 1870 mAh , always reaches 100% with this charger. (I have two of these chargers since I bought another one as backup - both do the same thing)

That could be the case. Yet, for two weeks, the Qi charging had no problems taking the charge to 100%. It would charge a bit over 15% an hour. The Galaxy Charging Current app reported between 670 and 750ma charging current using Qi charging.
At this point I'll likely never know, but it could be the battery itself simply failed on the tablet. My question is mainly to see if anyone else has used Qi charging, and what their experience is. How can I display the battery status (you referenced lv 2 (good) to ~ lv 4 (bad))? The battery app from the Play Store does display "battery health" but I've only seen it say "Good".
On your side note, I occasionally plug the tablet into the USB port on my computer (measures 5.10V), and it charges at about 10% an hour while sleeping, and has repeatedly charged the battery to 100% when I leave it connected. I have an EnrePlex Jumper Prime 4400mAh that measures 5.18V, and charges at 1.5A. It has charged the battery to 100%, though will run out of juice if the battery is lower than 40% before I use it, it measures 5.18V.
I have an old Galaxy Tab 2 10.1 that I often charge via the computer's USB port, although it takes a long time, and it's battery is still fine after almost 3 years.

The battery app from the play store probably does the same thing just shows a status as a replacement of the health, you can see the status with logcat occasionally you will see something like this ---
you might need root for some of these commands., you can use Terminal Emulator , adb shell, or sshd to access these commands.
Logcat::
1.
"D/BatteryService( 934): level:83, scale:100, status:3, health:2, present:true, voltage: 4091, temperature: 234, technology: Li-ion, AC powered:false, USB powered:false, Wireless powered:false, icon:17303447, invalid charger:0, online:1, current avg:-378, charge type:0, power sharing:false"
2. (shell)
dumpsys battery
will output something like this
Current Battery Service state:
AC powered: false
USB powered: false
Wireless powered: false
status: 3 < - unplugged
health: 2 <- health:2 would translate to good , health 1 would be excellent (though I have never seen a 1 status , 3 poor, 4 bad
present: true
level: 83
scale: 100
voltage: 4114
current now: -140
temperature: 248
technology: Li-ion
3. (shell, you can check out other files in the /sys/class/power_supply/battery/directory but be careful not to modify them)

UCH10 Fast charging not working

I have just bought the UCH10 from Sony to try out on the fast charging, its seems charging at the same rate as a regular 2.1A Charger.. Anyone facing this issue?

I don't know about the UCH10, but I know with my Powergen charger I see it going into HV (fast charge) mode. (The charger I have has an indicator for when it's in 9v mode).
However, I have noticed this device's thermal throttling is pretty aggressive. You need to let the thing idle if you expect it to charge at any reasonable rate thanks to the Snapdragon 810 being a power hog.

Confimed the UCh10 charger fast charge working
Only got 13% from 1% for 15mins
What happened!!

Mine came with the UCH10 charger and am using my short Sony usb cable that came with my headset (EC300). I went from 4% to 100% in 1 hour and 35 mins. At the end of the day with my bluetooth headset and smart watch conneted all day (12 hours) moderate use emails,mms,calls. I have about 42% remaining. It only seams to be getting better with each charge. Today it went from 5% to 100% in 1 hour and 22 mins.

Perheps Sony's fast charging is to speed up overall charging at a faster rate. As i was from Note 5, its charging takes only 10 mins to jump from 5% to 38%!!
Perheps they are both using different fast charging tech?

Both are using the same under different names. Samsung named it "Adaptive fast charging" and the rest use qualcomm's name "Quick charge".
For example mine is in the box with standard 1.5 normal charger, but I am using the charger from my dead note 4 (yes it is a quick charger one) which is charging z5p at the same speed like my note 4. Also I am monittoring the charge rate, and I can confirm that samis Adaptive charger charging at max using qualcomm's quick charge standard our z5p devices.
Edit:
If note 5 charging so fast it must be another tech from Samsung (or wrong battery stats - believe me I experienced these few times on my note 4 during flashing AOSP roms).
Cheers
Edit 2:
I can remember that note 4 when stock (tw) is charging much more aggressively during initial charge (upto around 50%, and then it just slow down), while AOSP is fast charging constantly (lower rate compared to samis stock tw rom) but use quck charge upto 90-95%.. It is a setting at the end. Yoi can force set this with custom kernel.

Is your phone quick charging ?

I used a few Qualcomm Quick Charging phones before, quick charge 2.0/3.0 and they were all pretty quick to charge, like 30 mins 60%. Just before the Razer I had the Oneplus 3T which used the Dash charge technology and that was like superquick.
The razer supposedly has the latest QuickCharge 4+ technology.. but I am yet to see the phone charge "QUICK".
When connected with the original razer wall charger, It is maxing at about 1920Ma using 4.01 V. (checked using ampere app)
I also tried a different usb c cable, on a different quickcharge 3.0 wall charger and it is giving me exatly the same output at 1920Ma max.
This is not right, is anyone else experiencing similar charge speeds ?

Don't know the electrical figures but performance wise mine charges to 60% in the first 40-45mins.
But then sadly it takes a while to finish the full charge. Like another hour.
On the lockscreen it states 'rapidly charging' so it seems to be using the technology. Remember this has a 4000mah battery, what phone were you using before?
That being said I'm getting fantastic battery life so in my case this doesn't bother me.

Good batt life here too. About an hour and 50 minutes from 4% to 100%.
Not sure how right that is. I think it was prolly 30 to 40 minutes to 50% or so.
Funny thing was, I charged while the phone was off, the white icon on the black background showed 100% (no numbers but it was full) but when I started the phone the battery status was 95%.

Ok, I got the other phone replaced because it had couple issues. I put this new phone on charge last night when it was on 7%. On the ampere app it maxed out to like 3000 something Ma and there was a buzzing/whining noise coming from the charger/wall adapter. I left it on charge till like 40% or something and I was not comfortable with the sound from the charger so i removed it.
Put the phone on charge today, it was on 35%. The sound from the charger is still there but not as loud as yesterday. Checked on the ampere app, its pushing on average 1900Ma this time.
35% at 11:27
50% at 11:45
61% at 11:57
75% at 12:13
91% at 12:34
96% at 12:48
1. I still feel the phone is not charging fast enough although it is saying rapid charging. Like mentioned before, connecting the phone to a lower standard quick charge 3.0/2.0 power port is charging at the same numbers..
2. Having looking at these links below, the numbers dont add up to what they are advertising quickcharge 4+ with.
https://www.qualcomm.com/products/features/quick-charge
and https://www.qualcomm.com/news/onq/2...alcomm-quick-charge-4-your-next-mobile-device
3. I've never had any charger/ wall adapter that made such noise. Is this a defective unit, or is such noise on these expected if it is like charging at a faster rate? the previous one was queit.. but then again the previous one did not push over 1900Ma, this one got to over 3000Ma.

Don't know what to tell ya, but I've heard zero noise from the chargers, I've got 2 units. Purposely kept my original instead of using the rma'd charger just in case. I'm not sure what their total sales are vs defective units, would be nice to get some communications from razer though.
I'm glad they got an update out after 5 days, shows they're working on it, but the update broke the sound and there's questions people have, all razer seems to do is say 'contact customer service'. Which isn't very cool when you're sitting there wondering wth is happening with the direction of it all.
Still love the phone though. Best specs of anything out there, sounds like just as many bugs as the pixel 2 or the iphone x too. heh
And it's a bonus to razer since this is their first and those companies have been doing it awhile.

Just changed out the charger for a leeco rapid charger it is rapid charging now looks like the wall charger they sent us are bad. That sucks time to call and complain. Also the USB cable is to thin to support rapid charging.

I was on live chat yesterday, they said they will go through with the warranty team and try send me a new charger. They will probably just send out the same thing. The dash charge cable my oneplus 3t had was proper thick and that was charging at around 3000-4000mA on average till like 60%, then it would usually slow it down but that was a proper quick charge.
I connect this cable, it pushes to 3000mA for like 5 seconds and then goes back down to 1900mA. I think its either that the equipment they are using is just crap and not ready for quick charge or that they have large number of defective charging units.

Sad to be bumping this but I also have huge amount of noise coming from the charger, I have to say that 60% on standard phones is half or less of what 60% on the razer is, but yeah there is no difference for me from QuickCharge 3 and 4+, it's quite weird.
I'm going to go through and get a new charger, also the cable's lining is also ruined somehow, detached from one of the USB-C ends and as far as I can see seems to be protruding some alloy, most likely just some protection but it's really just what usually happens, also with mices from Razer.
Goodluck to everyone.

I'm using both the included one and my old nexus 6p one and both charge rapidly and pretty freaking fast too

I've come to a conclusion and still awaiting feedback from Razer aswell to confirm this, that either my phone is defective or Razer are claiming to have this phone equipped with QC 4+ but it really is not.
Qualcomm say:
When Quick Charge 4 was announced, it promised to bring even faster charging than its predecessor, allowing a device to go from empty to 50 percent in just 15 minutes.
The current Quick Charge 4 technology, announced in November of last year, promises five hours of charge in five minutes, a 20 percent improvement in charging speed and 30 percent improvement in efficiency than the previous Quick Charge system.
The company announced even more improved specs today: the Quick Charge 4+ system, which the company promises is up to three degrees cooler, up to 15 percent faster and 30 percent more efficient than Quick Charge 4.
So can anyone confirm that you are getting these numbers when charging your phone? No way near what Im getting. I've tested and compared the charge speed using Ampere App and could not see a single difference between QC 3.0 and 4+ on this phone. I've used the original wall adapter + usb c cable combinations as well as using a standard QC 3.0 wall adapter and a usb 3.1/3.0 cable.
The phone starts charging at around 3800mA upto 25% then reduces drastically to 1800mA and charges to full charge. Issue lies here because at 1800mA the phone is NOT quick charging. It charges quick upto 25%, very quick actually but after 25% it charges very slow. I know the fact that due to heat the phone will not charge at 3800mA throughout so would need to drop but this drop should not be at 25%. My oneplus 3T used to charge at around 3000-4000mA 60-70% then used to drop towards 1500mA-2500mA mark and would complete the charge at this rate. It was very quick, 0-70% was like in 30 minutes.
This is what I've got yesterday.
Started Charge @ 14:53 / 15% / 3800mA
14:57 / 21% / 42 mins untill full
15:01 / 26% / 44 mins untill full

16:30 / 96% / 5 mins untill full
16:38 / 98% / 3 mins untill full
16:45 / 100% / Charged
Took 108 minutes for full charge from 15%. This cant be right for sure? Can anyone confirm.
Note: I've had no apps running or anything in the background. Also note at 14:57 it said 42 minutes for full charge, 30 minutes later it was still saying 42 minutes for full charge

I think I'm going through the same thing. I'll charge and test it.

My experiences are similar to others. I am not using the box charger. I am using 2 types: Motorola TurboPower 30 USB-C, and the AUKEY 70W Charging station (Using the QC 3.0 port). I have no idea if its doing QC4+.. It just says "charging rapidly". I am using an app called AccuBattery pro. It is at 85%. See the attached picture for the metrics charging on the Motorola charger. The one thing I miss, which my Nexus 6 did without an app, it would tell me how much time until full.

I have the same exact issue

Can you guys all test your charge using the Ampere app and jot down the numbers like I have done. Make sure you put it on charge when the battery is below 25%. If everyone is getting the same numbers then the phone does not come with QC 4.0+ and/or it cannot handle heat properly hence it is only charging quick upto 25%. Or else, some of us have bad units.

I'm experiencing the same behavior you are using the QC4+ Charger and cable that came with it.

I did get in touch with Razer and at first they were not willing to accept that there is a problem and they were insisting that the behaviour was normal. After forcing them to "explain" why it was normal, they could not really say anything so they gave up on it and now they are saying I could send the device in for them to check it. I also got the half screen freezing issue which I believe is a hardware problem (somewhere on this forum and Razer forum confirmed) so I have just put a RMA request and will be testing out the replacement device when I get it. If the replacement phone is no different and all you guys are getting the same numbers then like I said, I dont think Quick Charge 4+ is implemented to their devices and its just "false advertising". I cant think of anything else.

Had the same issue charging stops at 20%
but the problem is not constantly appearing

Well so far we have yet to see someone come and say Quick Charge on their phone works after 25%.

Bit of a misunderstanding
So first of all Qualcomm states up to 50% battery in 15 minutes, but that will only hold true if used on the smallest of smartphone batteries aka round or just bellow 2000mah.
So technically 1000mah in the first 15 mins which will be about %25 of the razer's 4000mah battery.
Razer is selling the chargers themselves on Amazon on the razer store and in the description they quote up to %50 battery in 40 minutes which in real life means 50 percent in ideal lab situations.
So your phone and charger are working correctly and at the maximum nowadays technology allows.
Just always remember with anything new that comes out with technology like when they touted the up to 4g speeds theoretical limit this and that etc hardly anyone if ever anyone will ever have the pleasure of experiencing the up to... that has been touted.
I hoped this helped and maybe clarified things for some people.

Just always remember with anything new that comes out with technology like when they touted the up to 4g speeds theoretical limit this and that etc hardly anyone if ever anyone will ever have the pleasure of experiencing the up to... that has been touted.
I hoped this helped and maybe clarified things for some people.

There is nothing to misunderstand here. The last phone I used had a 3400mAh battery and charged to 60% in 30 minutes. Razer has the extra 600mAh yes, maybe the charge technologies are not exactly the same yes agree on that too, but this does not mean that the 4000mAh Razer could only handle Quick Charge upto 25%. Whats the point of having the technology if the remaining 75% is going to be slow. Doesnt make any sense, Quick Charge 3.0 devices dont work like this so why should it be this way on this phone.
Took 108 minutes for full charge from when the phone was on 15%. Said 42 minutes for full charge. 30 minutes later it was still saying 42 minutes for full charge.
Im just not convinced that Quick Charge 4+ is working as it should on this phone. Either software or hardware related dont know but something is wrong. On this forum or the Razer forum cant exactly remember but some guys were saying how the provided usb c cable was not even a proper usb c cable and it was too thin. Just thinking maybe that might also be a reason or maybe not i dont know.

For a 3400 mah battery to charge to 60% in 30mins you would need more than 7amp charger .
I don't even know one if they exist.

I thought this was a fast charge device

Compared to my S8 it does not charge fast, is there a setting I need to enable for fast charge?

You have to turn off battery care or else the last 20% charges very slowly.

According to my research, with battery care it charges fast(8V 1,5A) until 50% of the battery, then it goes 5V 1A.

Are you using a Quick Charge enabled charger or the standard one delivered with the phone?

I did some tests today at work, charged from 0% to 90% with battery care ON, and bluetooth ON.
0:00 - 0% - 8,6V 1,3A
0:04 - 5% - 8V 1,3A
0:08 - 10% - 8V 1,3A
0:18 - 27% - 7,7V 1,3A
0:26 - 33% - 7,7V 1,3A
1:00 - 73% - 5,3V 1,3A
1:19 - 85% - 5,8V 0,6A
1:30 - 90% - 5,5V 0,6A

I don't have this phone but try installing Ampere from the Play Store. If you see it charging anywhere in the 2000+ mA range it's doing Quickcharge. Keep in mind it does so up until 80% I believe. At least that's what my Axon7 does but I believe that's how Qualcomm Quickcharge 3 is designed- to rapidly charge until the last bit to maintain battery health. Notice the numbers in the person's measurements above how it ramps down after 80%.
Also, if you purchase any 3rd party chargers make sure to only buy models Qualcomm says are certified for Quickcharge. There's a PDF on their site that lists all of the certified chargers.
My Axon7 will charge at around 2300-2400ish mA until 80% and then drop to around 500mA for the remainder. I also might have to reseat the cable if it's not kicking in.
But that last 20% is by no means quick. That's why these fast charging technologies advertise them with slogans like "15 minutes for 2 hours charge" or whatever. The slogan only applies to the quick charging timeframe - you will get a couple of hours if, say, you began charging at 25% . If you want to get a full 100% it'll still take an hour or more to trickle charge the last 20% or whatever.
Personally, I bought a certified Quickcharge 3 charger for my car and 1 for the house, the OEM charger I use at work, and at night I use an old charger that isn't Quickcharge. It's really mainly handy for the car when you need to get that oomph when you're out and about.

Question S22 Base Charging Confusion / Poor Charge Speed

I have had my S22 base for about a week, and while I am still concerned with the life I'm getting (same apps and usage pattern, about 4+ hours of SOT and 15 hours of mixed use) vs the S9, I had decided to keep it until ...
I can't get the thing to super/fast charge. I do not have a Samsung charger (waiting until I get my voucher) but do have a number of 15W and 25W PD-compliant chargers that work on everything from my S9 to my laptop. Unless I turn the phone off, all of those chargers charge S22 at a rate of 10-20% per hour, with Accubattery readings in the 200-1100 maH range, NEVER a value over that. The battery temp and voltage are well in spec. It is currently plugged into my laptop PD compliant charger at a rate of 900 mA with a "time to 100%" of 30h.
Likewise, I bought 2 car chargers that are S21 certified as well as QC3.0 and PD3.0. It has a 30W port. I used the cable that came with either charger (I've tried a ton of cables) and sometimes it gives a "0mA" reading while other times it goes 200mA-800mA at a good voltage. That means while I don't lose charge, I also don't gain. On my 30 min drive home I went from 23% to 24% with dark mode and no apps running.
Finally, to extend the mystery, depending on which aftermarket charger I use the phone itself thinks I'm Fast Charging or Super Fast Charging, reporting that on the lock screen and battery screen. On that screen it says something like 30m to 100% even though the observed charge rate is much lower.
Samsung won't talk to me unless I'm using a Samsung charger and I can't wait until I get the voucher/those are in stock ... I have 5 days to return it and unless you can help me (Obi Wan) I'll be back on that track.

I use my old 25W (original from N10+) charger and it takes about 1 hour to charge from 15-20% to full. I have the DevCheckPro app showing me at the start 17-18W and about 6-7Amps of charge load initially, at the beginning.
