Latest OTA draining battery while charging?

I've noticed ever since the latest update, two HTC ones that I have are charging very slow.
I.e. if using GPS/navigation my car charger cannot keep the battery charged or when just using the phone itself. (Not while driving if course)
When on the previous OTA update it was fine. Yes they charge in AC mode. And the charger I have is rated for output at 2 amps just like my home charger which is fine.
Anyone else having this issue?

thats because your max output on the car is 500mA and that is not enought to run the phone and charge at the same time. Even if the charger is rated at 2amps the phone wont know and default to USB charging speeds.
To test this go to the battery and see if it says AC or USB:
USB max is 500mA
AC max is 2A
even thought the charger says it can do more, the phone doesnt know that unless the data pins for transfer of data are shorted indicating the phone is allowed to do AC charging.
EDIT:
More info on how to hack it to force AC charging:

That's the thing it does charge in A/C mode, not USB.
Which is odd, it only started after the last update in May, and its happening across two identical HTC Ones. Both are s-off boot loader unlocked running same version/software etc...
Basically it charges in the A/C current but is dying during charging

If you are s-off and unlocked what rom are you running? also do you have a custom kernel installed?

oh wow, if it says AC and its still dying while charging thats not a good sign. Are you 100% stock locked, s-on??

its been one of those weeks. i was looking at the OP.

Happening to two phones? Bad charger, go get a new one. Or test it if you are unsure, hook up a meter and check it out. But two phones losing charge while in AC mode on the same car charger screams "bad charger" to me.
Edit - Also, assuming your household charger works fine - and that is AC mode charging also, it pretty much narrows the culprit down to that charger being bad. If it was a rom issue it would be duplicating the issue on any charger it saw as AC.

If I recall you will get a "Slow Charging" notification if you're charging with less than 500mA. If you're seeing that notification then you're more than likely going to struggle to use GPS while charging at that rate.(It would take nearly 5 hours to fully charge that phone with it off using such a low amount of current)

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Nextbit Robin can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Charging speed with a Quick Charge 2.0 adapter is as expected: excellent. It is in line with other phones with the same capability.

Will Quick Charging work with my Motorola Turbo charger if I use the Robin cable on it?

I'm not sure, but I've tested it with Aukey (wall) and Anker (car) chargers, both work fine with Quick Charge 2.0 speeds.

I charged with the official charger and a Iselector Qualcomm quick charge and nothing as well. Iselector worked on both the V10 and G4. Not sure why this is not working

Nevermind. Charging fast now. False Alarm lol

I thought the charging speed was great when I wasn't paying attention, but when I did actually pay attention and time it, it took about 1 hour and 40 minutes to fully charge. So, I would check into that. Also, the Robin doesn't seem to be USB-C Power Delivery Compliant to deliver the rapid charging like the Nexus 6p and Nexus 5x does, so getting fast charging from USB-C chargers that take USB-C to USB-C cables is useless, you'll get standard speeds. So please implement USB-C Power Delivery in the successor to the Nextbit Robin, so we can enjoy that fast charging technology as well, in addition to Qualcomm Quick Charge fast charging technology.

I am waiting for my Robin to be delivered. I am really confused about the charger. Does it show anything on the screen when a proper quick charge 2 charger is used. Like, in my Nexus 5X when I use original charger it shows "charging rapidly" but when I use another charger it shows "charging" or "charging slowly" depending on the source.
I'm from Bangladesh and it's hard to find a certified QC 2.0 charger. Is it ok if I buy a charger which is has 5V2A or 9V2A or 12V1.5A written on it?

What version of the os?

With a Qualcomm 3.0 charger and 3.0 cables, I get 2500ma speeds (12.5w). Only when charging from less than 50% though. The charging speed slows down as you approach 100%. The lock screen should say "charging rapidly" if it's working though.

Android 7.1.1 with nextbits original firmware

Does the S9 support Qualcomm Quick Charge 4.0 or 4.0+? Or even QC 3.0?

I haven't seen this mentioned at all or not sure if the s8 supported qc 3.0 or Power delivery but does the S9 support QC 4.0 or 4.0+ or even qc 3.0 or Power Delivery like the Pixels?

According to GSM Arena, only Quick Charge 2.0 is supported...

QC 2.0 in a 2018 flagship phone is blasphemy.
Apparently USB-PD is also supported but is throttled.

Seems like samsung is treading lightly when it comes to battery, who could blame them.

The Note 8 supports Power Delivery, so I assume the S9 will as well.

While I see that it only is rated for 2.0, I've gotten used to 3.0 with my LG phone. The G6 charges fairly quickly. I would miss the fast charging speeds if it isn't as fast as the LG.

I'm looking forward to any fast charging aspect since my current phone doesn't have any of those features. Since Apple hasn't "invented" it yet...

Oh yes... my bad forgot they do have that function, just with the included accessories it still doesn't "fast charge" because apple wants you to purchase the $30-50 cable or wall charger to make it happen.

I noticed that charging takes around 30mins longer on my s9 compared to my s7. I'm not sure if that's because it might have a bigger battery or they've purposely slowed down charging to prevent an explosion lol. The phone doesn't seem to heat up while charging like it did with my s7.

It does have the same battery size. Nice that it doesn't heat up the phone.
By chance where you using the phone while it was charging? It will kick it from quick charge to standard charge if the display is on.

True...ish.
I use Anker's 30w charger (and I do use Apple's USB-C to Lightning cable). It wasn't that big of a deal for me because I needed a new work/travel charger setup anyway.

Nope I leave it since I'm aware of that limitation. I prefer the phone to heat up tbh and charge 30mins quicker!

No, it is not. Not even my S7 Edge did that. Fast Charge stays regardles if you have the display on or of, if you're using the phone or not. I heard (but not confirmed tho) that this happens during WIRELESS CHARGING. This I don't know and cannot say if it is true or not. But the fast charge with the original Samsung wall charger will not switch from "fast" to "normal" unless it's an issue

When fast charging my charge voltage wont go above 7.5v when the QC2 spec alows 9v and 12v.

There was annoying sound coming out from the usb port of the S9+ when i plugged the device using Anker QC3 charger.

Curious to hear other experiences, but my T-Mobile S9+ is very erratic with PD support. Using Anker's latest five port charger with PD, my S9+ will start indicating "fast charging", but will always drop back to "cable charging" at a very slow speed. Hmm.

On my S7, and I'm pretty sure the Edge uses the same charging technology, it'll switch from [email protected],6A=~15W to [email protected]=~5W after I turn on the display, just because it says fast charging that doesn't mean it's actually doing that. Have you tried it yourself using a USB power meter ?

When it switches, the notification also change from "fast charging" to "cable charging" or something like this.
If it is still displaying "fast charge" I really doubt that Samsung would charge it normally. More than that, it would be something everybody will brag about and be a well known issue and it is the first time I hear about it. For wireless charging yes, I heard this...but never for cable charging.

There are results when you google it, for the S7 and S8, I guess it's not that big of a deal because it displays "fast charging" and because people expect the phone to charge slower when active. Fast charging while being used was also the big selling point for "Dash charge" the fast charging tech from OnePlus.
It also says so in the manual on Page 12 :"You cannot use the fast charging feature when the screen is turned on. Turn off the screen to increase the charging speed" http://downloadcenter.samsung.com/c...G935_UM_EU_Marshmallow_Eng_Rev.1.0_160219.pdf
But to see it with your own eyes, just get yourself a cheap USB power meter and measure it

Fast charging => slow. Cable problem?

4 days and problem with charging already? ^^
When I use the cable usbc in the box, impossible to have fast charging anymore.
But when i use the cable of my s7 + the adaptator of the s9 => no problem.
It's the cable, I presume? Have you notice a problem with yours?

No problems so far. Fast charging every time. Seems like cable issue.

Mine fast charges but it never hits 9volts only 7.5v

I have tried 2 chargers (provided by Samsung) for my S9 Plus and Im still not getting a fast charge. It take around 3-4 hours to charge my phone and that usually when I am starting out around 20%. Has anyone else had this issue? I'm wondering if I have a bad phone. I cant imagine 2 chargers being bad.

It seems that you've answered your own question. I have a ton of usbb cables so I just got a pack of adapters and been using it and getting fast charging since.

you need to go for samsung warranty in your city, or to go where you purchase your mobile, to replace your cable or to replace your mobile or to fix your problem, may the problem in connector of the phone, or need software.
good luck

If I turn on fast charge it takes of 10mins calculated time to full charge, is that it ? Is that all we get for fast charge a decrease of 10mins?

I have a Strange Issue. When i connect Samsung Original Charger And cable....Sometimes its shows Fast Charging....But my battery discharge. While Showing Fast Charging there is no time to full notification not shown. when the message shown chaging works perfectly. It looks like a Software issue

Do you have another cable you can try? Or another charge from a prior Samsung phone?

warp charging issue

Warp charging doesn't go beyond 3.5Amps on ampere app causing slow charging rate shouldn't it give close to around 5.2Amps charging speed? Can anybody share their screenshot or is there a issue with my device

With Warp Charge there are several factors that come in to play. The charger itself, the USB Type-C Cable and your device.
Has Warp Charge ever worked on your device?
When the cable is connected do you see "Warp Charge" displayed on the screen?
Did the Ampere App ever show the maximum 5.9 amps or does it always show a maximum of 3.5 amps?
Are you using the original Warp Charge wall outlet adapter and original USB Type-C Cable?
If Warp Charge was working before, how long has it been since you last saw it work?
Have you modified the device at all?

Yes it was all working before I have earlier got 5.2 to 5.5 amps but from past couple of months it's been fixed at 3.5 amps now, and yes I have been using original warp charger provided and no haven't unlocked or rooted my device, could this be a problem with the device or any other fix for this?

Bought mine 2019-12 . few days ago (2020-03-30) warp charge stopped working, it still charged, but extremely slow like 40 percent an hour. When it was off i tried plugging in charger, but it started looping, it didn't boot to an animated picture with charging battery, but it still could boot into OS when power button was pressed. Did a factory reset, didn't help. Connecting to pc usb still recognizes it. Had a feeling it was a hardware error. Maybe fast charging module went bad.
Sent it for a warranty repair, got an answer that it will take more time because it was sent for an higher level service. I guess it's quite bad, it could be a motherboard fault.
I read on oneplus forums that quite a few people has a same issue.

Connect it to a pc, see if it is recognized. Mine stopped working & it was a bad USB Car port. It would still slow charge but no warp charge & no windows pc would recognize it connected

Hi! I have the same issue, only difference is that mine is sometimes charging at warp speed and most of the time at 3300 mAh "dash speed". Did you manage to see what the issue was?
