[XPERIA X1 Q&A, Help & Troubleshooting] XavierGr:
I doubt it, have you used an ammeter to be sure about it? Even if that is true 1.5 Amperes for USB is clearly out of spec and completely up to the manufacturer to support it. The USB specification says it clearly, 500mA per port/controller.

That could help with faster USB charging indeed, though I don't know exactly how that cable is manufactured and it is clearly neither a standard cable nor described by the USB spec. Theoretically though it should work like a charm, I can't imagine how it could harm the device (if the wirings are correct).
[XPERIA X1 Q&A, Help & Troubleshooting] VaThInK:
You're right, but they have improved it for some time now.

Quoted from the Wiki:

"On-The-Go and Battery Charging Specification both add new powering modes to the USB specification. The latter specification allows USB devices to draw up to 1.5 A (low and full speed or 900mA in Hi-Speed mode) from hubs and hosts or up to 1.8A for dedicated chargers that follow the Battery Charging Specification."

http://en.wikipedia.org/wiki/USB

About 3/4 down.

I'm an electronics enthusiast and I have proper measuring equipments. Both my Fluke 289 DMM and its clamp meter adapter shows ~1A when I was experimenting with Cree Q5.

As I mentioned earlier, maybe X1 only requests 500mA from the USB port instead of the proper charging current.
[XPERIA X1 Q&A, Help & Troubleshooting] XavierGr:
Interesting, I wasn't aware that with USBOTG they updated the specification, my bad....

Still, maybe the members having problems have older USB ports. Do you charge your X1 and get very long charging times with the same USB port that provides 1 ampere for you?

Also what is the rating of the official SonyEricsson X1 charger?
[XPERIA X1 Q&A, Help & Troubleshooting] VaThInK:
I don't own an X1. I have TP instead and my TP is fine charging via USB. Took about 2.5~3 hours from 5% to 100%. Stock charger for TP is 1A. I haven't tried charging mine using the AC adapter as I assume it should take about the same time. Hopefully someone with an X1 can measure the current consumed when charging via USB. Also to all X1 owners, does your X1 gets warm (a bit hot) when charging via USB? As I said earlier, I have a feeling that they might have limit the current on purpose for some reason. Or you might be right when you said that people that are having this issue might have older USB ports on their PC. I think this is not a wide spread issue as not many people complained in here. ;)

USB OTG

Hi

Not all USB ports out there support USB OTG. You'll be lucky to get 1.5A out of a laptop/netbook for instance. As with all specs, sometimes they don't get 100% implemented - additionally, where there are several sockets on the same hub they may share the same 500mA.

I work for a company that develops USB devices for the healthcare market (ECG recorders), we have had issues with USB host hardware that does not adhere to the specs...

When a USB device enumerates, it tells the USB host what its power requirements are. There are several thresholds here which put the device into certain categories such as 'low power device'. On some hardware, if the device draws more juice than it said it was going to, the PC disconnects the power and then re-applies it - causing the device to re-enumerate. I had this on my Tytn II, and you could see exactly what was occurring by connecting a USB analyser in-line.

It would be possible for the X1 to query the host to see if it supported OTG, and request power appropriately, looks like they dont. One has to remember that USB OTG is relatively un-deployed in the field - it may exist on the devices wanting to be charged, but I bet its not present on many USB hosts out there.

When a device does not attempt to enumerate, the port that it is connected to will hand out 500mA. One could connect to 2 ports at the same time, but in some poorly implemented scenario's this may mean that each port supplies 250mA because the ports share the same 500mA. I dont know whether an OTG port will hand out 1.5A when no enumeration takes place.

Mine charges fine over USB with no issues at all, takes around 2 hours to reach full charge which seems fine.
[XPERIA X1 Q&A, Help & Troubleshooting] jackleung:
As many already said, I think the 500ma is the minimum it has to supply and it's up to the system builder to decide the max. I had a Western digital portable hd which is very picky on current and the quality of the USB cable. All of my desktop (Asus Maximas MB and MicroStar ...etc) can't start it without supply the secondary power source in the Y connector. But my Asus EEEPC can power it up w/ it's own w/o problem.
[XPERIA X1 Q&A, Help & Troubleshooting] VaThInK:
I can assure you that I'm able to suck 1A from my PC USB port without enumeration and the host didn't cut the power either. I haven't tried to push it to 1.5A because I'm afraid my LED light would die.
[XPERIA X1 Q&A, Help & Troubleshooting] ahlok_hk:
I think that USB charging is slow because of a design flaw of X1.

Unlike my Tytn and Wizard which totally turn off the backlight after some time, when the X1 is connected to the PC using USB, it on lower the brightness but keeps the backlight on no matter how long you set it to off in "Setting" -> "Power" -> "Backlight". That is a waste of power as I guest the ATI graphic chip in the X1 is a power drainer.

As I result, I notice that if I turn of the screen using the power button, the charging will be a lot faster. I hope Sony Ericsson or HTC would fix it issue soon because it is really very inconvienent...
[XPERIA X1 Q&A, Help & Troubleshooting] dwd:
There is some kind of problem with the usb charging, i just tried using the usb port on my computer, it says it is charging, but nothing is happening, but after a power off/on on the x1 it starts charging and the battery meter is going up.
[XPERIA X1 Q&A, Help & Troubleshooting] ikeabuchi:
Just needs a driver update, Its not requesting the higher current mode of the usb 2 standard, I made a small interface that plugs into it just as a test to enable this mode, and all is fine, I can see without the interface it takes a while to charge but when im using it as a hsdpa modem the t=slow trickle charge is welcomed to be honest since the time on the net offsets this so the time i finished its charged up, hour or so
[XPERIA X1 Q&A, Help & Troubleshooting] erichui:
I don't see how this is a design flaw? I haven't actually tried it myself since I prefer to shut down the screen manually but there is a setting to turn off device if not used for "x mins" ? Then just set it a timer if you wish it to be shut down like when it is on battery power the screens turns off after 1 minutes.

Without such a setting people are going to complain saying "I want my screen to be on when charging" in scenario such as when mounted in a car. I know I would complain if they force my screen to be shut down when charging.

And while I haven't used many Windows mobile, all the ones that I have used seems to have the same behavior as my X1 (imate JASJAM, dopod c730)
[XPERIA X1 Q&A, Help & Troubleshooting] ahlok_hk:
I guess you should try it before you give any false comment.

My test settings on X1 are:

On battery power:

turn off backlight after 1 min

turn off device after 1 min

On external power:

turn off backlight after 1 min

turn off device after 1 min

My test settings on Hermes are:

On battery power:

turn off backlight after 1 min

turn off device after 1 min

On external power:

turn off backlight after 1 min

turn off device after 1 min

Even if I set the X1 to turn off after say 1 min (when on battery or charding), it still keep turning on with backlight ON if I plug in the usb sync cable. This is totally different behavior compared to my Herems (equv. to your imate JasJam) which turn off backlight completely after 1 minute. I have tested it myself many times.
[XPERIA X1 Q&A, Help & Troubleshooting] erichui:
well I just did the test you have mentioned, you are right that the device does not shut down on external power "ONLY" when connected with the computer with the USB cable. However it does shut down when connected to a power point (such as using the AC to USB powerpack that came with the device).

I also tested device shut down on my dopod c730 and the device does turns off when plugged to the usb port on the computer.

Don't have the JASJAM with me so can't really test it.

I guess the conclusion is that SE have a bug with the device not turning off on external power when connected to the USB port on a computer. Probably best to report it to them I guess.
[XPERIA X1 Q&A, Help & Troubleshooting] vinokirk:
I have had two X1's due to a contractual error with Vodafone, and I had to take my first one back. With my first X1, when i connected it to USB the battery icon didnt change, it just stayed as a battery and I left it in my computer with teh battery nearly drained and after 9 hours it only had 2 battery bars.

With my new X1 when I plug it in to the USB the battery ico changes to a plug ion, just like it does when you plug it into the mains, and it seems to take about 5 hours to fully charge!

So (maybe a poll should be done?) who has the first scenario and who gets he second scenario?
[XPERIA X1 Q&A, Help & Troubleshooting] VaThInK:
Personally I believe that they've done this on purpose. Because when it's connected to PC, the phone will not go into standby mode to keep the data connection alive. Otherwise it would be very annoying if the phone goes into standby when you're in the middle of transferring big files. I could be wrong, but I think this is the reason why.
[XPERIA X1 Q&A, Help & Troubleshooting] erichui:
well that could be one of the reason too, however I will have to test it out first. I haven't actually tested it on x1, but according to my own experience with the imate jasjam when the device is plugged in to the usb port and the device shuts down, my active sync would lose connection too, which was very annoying because when I am doing debugging of applications using Visual studio.

Of course I guess that is the whole purpose of the check box of external power settings.

It doesn't really bother me since I prefer to have it shut down manually anyways, but it could bother some people.

vinokirk regarding to your charging issues, not trying to make you sound stupid but did you verify that under your "Power" Settings, you have the checkbox "When device is turned on, do not charge the battery when connected to the PC" unchecked right?

One more thing is, did you try with another USB port? I can't recall if it actually happened to me, but I think I might have experienced that sometimes when plugged into certain port the charging icon doesn't actually comes up, and I assume that I might not actually be charging, so I actually need to try another usb port and it will work fine. (note that the same port might work again after a restart or something) This was experienced with the Imate JASJAM.

I didn't exactly calculate the time it takes to charge the battery from empty to full with the X1, but from my experience with the iMate JASJAM USB charging isn't exactly quick either, I wouldn't be surprise if it actually took 5 hours to recharge from empty, so the behavior about taking 5 hours to charge just seems normal to me.
[XPERIA X1 Q&A, Help & Troubleshooting] nek4d:
I remember on HP Ipaq 6815 there was a selection between fast and slow usb charging. The time difference was very big.

I assume that the X1 charges in slow mode from usb-PC.

Anybody knows a way or program to make it fast?
[XPERIA X1 Q&A, Help & Troubleshooting] Dandie:
I think mine charges fast when in USB drive mode and slow when in ActiveSync mode.

Slow charging is better for the battery though, so not too bad if you have the time.
[XPERIA X1 Q&A, Help & Troubleshooting] johnchan78:
Okay guys, I've had experience with this.

A few things affect the charging speed that you may NOT be thinking of.

1) Laptop or desktop: Laptops many times have low-powered mode and similar to save battery, and output less power to their USB ports. This depends on different manufacturers, but it is certainly something to consider.

2) CPU load: check your X1's CPU load. I found that, for whatever reason, charging from the laptop caused various CPU loads to spike up, whereas when charging from the wall charger, it did not have this problem. Also, the screen did NOT turn off much, or at all, when connected to the laptop, but would turn off when connected to the wall socket. I suspect all these issues are related to Activesync being on when connected to a PC's usb port.

3) One thing to consider... some portable USB HDs (the ones that connect only to USB port and get their power from the USB port, like the laptop-style HDs), usually come with a USB cable that has TWO (2) port connectors. That is, it connects to two of your usb ports simultaneously, and draws power from BOTH of them. I've seen USB HDs that could only power up properly using 2 ports (otherwise, you just hear a whirring-clicking sound as the portable HD fails to fully power up, which is when it uses most power). Same thing for the X1... connect one of these 2 port USB cables, and if your port isn't providing sufficient power, then 2 should.

4) Either way, the way I do things is... if I'm going to a meeting or need a quick charge, I always use the wall charger... you are sure to get the fastest charge that way... and if you want to sync and trickle charge, then laptop's USB ports.

This is my conclusion.
[XPERIA X1 Q&A, Help & Troubleshooting] crabby09:
Well... I thought I'd give it a go as I usually charge by wall socket.

The phone charged 40% in 10 hours. I have my computer set to 'performance so it shouldn't go into a low power state, but I think the USB port I used wasn't being fully powered anyway.

Will try a USB port on the motherboard tonight and let you guys know.

crabby
[XPERIA X1 Q&A, Help & Troubleshooting] maedox:
40 % in 10 hours! O_o

Then it's definately not charging the way mine does. From my laptop at work it is slow, which I expect, since it's a laptop. At home, when I connect it to my desktop monster, it charges from 40-50 % to full in between one and two hours depending on how I'm using the phone. It's usually in AS mode.
[XPERIA X1 Q&A, Help & Troubleshooting] alias_neo:
Same

On my desktop at home I get a full charge in about 2.5 hours, the ports are 500mA standard USB output.

My laptop however the battery will actually discharge faster than it charges (or almost), probably because the laptop ports generally only supply about 200mA-250mA and are more likely to go into a power save state.

It is possible to check the power capacity of your hub by ging to the USB port device in Device manager, it will even tell you how much the connected device(X1) is drawing.

HomeScreen++ is also helpful because it will show you a positive mA drain (instead of a negative figure for draining battery, you can see how many mA are going into the battery.

Note that the wall charger supplies 700mA.

The battery is 1500mAh, so dividing this by the charge current will give you the time taken to charge (in theory), although it will differ because of other factors.

1500mAh/500mA (standard USB port (desktop)) = 3 hours charge time.

1500mAh/~200mA (laptop?) = ~7.5 hours charge time.

(don't forget to take into account that the phone is draining the battery at the same time, so in reality it will take a bit longer.

[Samsung Galaxy S22 Ultra] mrlove6:
hey, great to see that. yet I do have important question please, I have already rooted mine 2 weeks ago, and had to roll back to stock as bluetooth policy/security can not connect to watch. system was not completely mountable. anyway to make it short :D did you tried if the watch can connect ? Is there is any chance flashed the rom on top of the current stock wipe data or something? can not rescue banking app and wait them to send me new qr code...
[Samsung Galaxy S22 Ultra] Williamtung:
Yes, do you mean the watch cannot connect to your phone because you have rooted? Then have a try at this https://github.com/3arthur6/BluetoothLibraryPatcher/releases/tag/v2.4.1 it attends to avoid losing bluetooth pairings after reboot or airplane mode switch on rooted samsung devices. It is required to fix pairing issues with Galaxy watch

About your system mountable problem, use 'ADB shell', then 'mount -o rw,remount /system'. Have a try whether it is working. I also suggest you can use MiXplorer. It can mount root rw-table.

About Samsung apps and Knox stuff, they won't working. For banking apps, if they only use safety net like Google pay, it will work. If not, like Samsung pay, it will not work
[Samsung Galaxy S22 Ultra] mrlove6:
It was all fine except bluetooth will never work even the patcher tried with dr.ketan to solve it, but seems that the new policy from samsung vendor is not mountable. Anyway according to bank and etc. it's also no problem, always works for me. My concern was: is flashing ur rom may lead in any chance to wiping data? Or 100% guaranteed no. If it may I'll try it on sunday so I can order the qr code from bank to install the app again, don't wanna risk it like 4 days with no bank app

[Samsung Galaxy S22 Ultra] JazonX:
Guys,

S22 - Root is not as the Models before this. Even though we have achieved root, We haven't achieved R/W capability in the partitions. For now, Only CSC mods can be done, and anything else needs to be applied via Magisk (Or TWRP when it comes).

Vendor partition cannot be mounted , hence the bluetooth patch will not work unless it's a module with the complete changes.

Also, S-Health will not work either, because build.prop cannot be modded to remove the security check.
[Samsung Galaxy S22 Ultra] Williamtung:
Ok, thanks.
[Samsung Galaxy S22 Ultra] dr.ketan:
Though system can not be mount R/W still lots possibility there to mod & fix. I have almost tested all my ROM features of S21 and no issue on S22U eother. Just tested GW4 and Samsung Health too just now and posted SS on my thread.

Even if this remain same forever, it's not end of development Probably we just needs to change scenario to use custom ROM with new method.

Use magisk 24.3 to modify AP from firmware with magisk, then use adb to transfer AP patched-magisk to pc.
