Just switch the HTC USB cable to the ipad charger
I am using the ipad charger rated at 10W 2A to charge the HTC Hd7,
its taking longer than usual to charge like instead of 2 hours, it goes to 3 hours
I did this after reading some threads about the galaxy tab having longer battery life after charging with higher rated chargers
I always thought that the HTC charger had a problem of not charging the phone fully. i also did notice it charges the phone fast but the charge foes not hold well
now its 3 hours charging on the ipad charger,... will update later how the battery performance is...

i have finished charging
under mango official rom i am running
battery saver says : 100 % ( 1 day 18 hours)
thats a whoopping 42 hours
something i never got with the HTC charger!
hmmm serious? what phone you on? 7720? curious on this.
I am using the Mango Asia Taiwan rom
Sounds good.. Might get an iPad charger and try it out..

That's pretty interesting. I wonder what others with HTC devices are getting. I just charged my HTC 7 Pro with the included charger on 7712 and it's reporting 1 day 12 hours.
I might get an ipad charger too.
How has the performance been?
It's cause some manufacturers ship high speed chargers (RIM, Apple), while others do not. HTC, being a cheapo manufacturer, don't ship them. They cost more than the normal chargers.
BB with 1500 mAh battery. 50% to full on a RIM charger in ~30 minutes or so.
HTC chargers are bad. I always use my Samsung chargers with my HD7. They seem to charge the phone up faster.
But make sure the charger you use is safe to use with that device, Lol.

MOSt chargers nowadays use the same USB connection scheme, so long its 5V its safe.
There is abolutely no difference between chargers, only charging time, if I am charging my HD7 with stock charger (1A), it´ll take about 1,23 hour to charge it fully, then it´ll cut the charging process to not to damage battery cells. If I´ll use USB (0,5A), it´ll be fully charged about 2,46 hours later, while not holding the charge when the charge process is completed (0,5A is simply not enough to feed the device directly so it is forced to use the battery).
However, If I´ll use 2A charger, I´ll have my HD7 charged up in same amount of time as stock charger (1A or 1,23A - same as a battery). So, the reading what your getting (1 day, 18 hours), is a big BS, everyone will get the same reading when not playing with a phone for a while, start some game for example, you´ll get 6-7 hours est. battery life. This is simple electrotechnics stuff guys...

i dont know it seem to make my phone last 50% longer but there was a battery indicator reporting problem, when it was down to 5%, it rebooted the phone and got 49%.
can seem the explain it,..
According to Qualcomm:
https://www.qualcomm.com/products/snapdragon/quick-charge:
In laboratory tests using a 3300mAh battery1, a Quick Charge 2.0 enabled device went from 0% to 60% charge in 30 minutes, while a device without Quick Charge 2.0 using a conventional (5 volt, 1 amp) charger achieved just a 12% gain in the same 30 minutes. A device with Quick Charge 1.0 managed a 30% charge in that time period.
Scrolling down on that page it shows the most popular Quick Charge 2.0 devices, the LG G4 is among them.
So the G4 3000mAh battery should be above 60% in 30 minutes if it uses Quick Charge 2.0.
I got this charger:
http://goo.gl/082zmj
Seems legit, but my charge times seem to be stuck at 1.0. That is it went from 19% to 55% in 30 minutes, which means it charged 36% in 30 minutes.
What kind of time have you clocked with your Quick Charger?
Also, my G4 got quite hot when charging.
Already a thread about this.

It will answer all your questions.
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

15:06 / 30% / 50 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.

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.
Ok so tmobile lg g8 wont charge up above 980ma current regardless of the charger or cables used and regardless of the battery level. So basically charging at less than 4 watts total. My one plus 6t will do at least 12 to 15 watts low battery charging.
What gives???
You might have a defective unit. I don't have any measurements, but my T-Mobile unit charges quickly with both OEM and third party chargers.
Ok did a test in stock charger took 1 hour 42 minutes to fully charge. Whats anyone else getting?

Could be the Optimized charging option in Setting/Battery. Uncheck and try again. This will slowly charge the phone to prevent unnecessary overheat and prolong the battery lifespan.
That option was turned off

Hi
I've not got the phone but as the charger isn't a proprietary one like Huawei and OnePlus the average charging time is about right. I had the HTC U11+ which had the same charger Quick Charge 3.0 and took over 1 hour 30 to charge.
Currently have an OnePlus 6T and the charger we get will charge the phone in over an hour.

Are you measuring the charge rate with the screen on? If so then that's your problem. Charging is limited to 5W when the screen is on to limit heat buildup. You'll need something like 3C battery monitor to record the rate when the screen is off. I've attached an example of my V40 charging on my Anker Powerwave 7.5 stand. With a wired fast charger it tops out at 2600ma.View attachment 4750253

I got a pixel stand before the upgrade and I could fast charge most of the time of a charging cycle. However after the system upgrade to Android 10, it now can only fast charge for a short while and then the temperature goes up to 42 degrees Celsius, and the charging current goes down to almost zero. The battery charges only 10% in two hours. It can never go up to 100% during the charge at bedtime of about 7 hours. Anyone has the same problem?
