[Galaxy S II Q&A, Help & Troubleshooting] dbzgod:
One is for JIG reasons, I know about flashing the older regular ones which I have for my Jig, but the other is if I need to claim warranty I need to be able to restore it completely, and Bell Canada for the GT-i9100M phone has a slightly modified Sbl that shows an M on the product name and no nag screen when you go into download mode either.

When I flashed to DXLP9 it has the new Sbl file in there and at the time I didnt know that it was going to change it around on me so I just want to be able to get the Bell one back if need be, but like I said before Bell doesnt have it in any of their firmware packages, the custom SBL is done at the manufacturing level and they dont publicly provide it.
[Galaxy S II Q&A, Help & Troubleshooting] Chainfire:
Do you honestly believe the Samsung Service Center will notice and/or care ? :)
[Galaxy S II Q&A, Help & Troubleshooting] dbzgod:
lol yeah I know. but still its not mainly about that, it is just one of those things where when something that bothers you and you just need to fix it/change it to the way you want.

I like poking around devices and figuring how to do what I wanna do, I know messing around with the bootloaders puts you into a chance of bricking but that comes with the territory, you live you learn, ive done simular things like this on other tech devices, and ive had great results the only thing ive ever bricked was an old Linksys router, but it had issues anyways so imo it wanst a loss and I got a newer one so it was all good and a great learning experience lol.

I do value all the input and opinons you and others have given though, its helped speed things along a lot.
[Galaxy S II Q&A, Help & Troubleshooting] shadowofdarkness:
One idea to see if a dd backup is ok to flash would be to get someone with a normal I9100 to backup theirs then do a "diff" of it compared to the file from a stock firmware download. If it matches then the I9100M's dd backup would be almost certain to work
[Galaxy S II Q&A, Help & Troubleshooting] dbzgod:
Yeah I have already done that and compared, I have a theory on how I can go about testing in a safer eviroment (kinda) and will test before I mess around with the Sbl bootloader, once it appears to be safe then maybe I will, still going over things.
[Galaxy S II Q&A, Help & Troubleshooting] dbzgod:
Lol my theory paid off and it worked ^_^ . I successfully have Bells Sbl packaged up in an Odin flash-able .tar.md5 (tested myself working great) and I also found out that the param.lfs from Bell is different as well (although only slightly different) ^_^ happy days lol.

Thanks for your Input and opinon Chainfire it helped a lot, and shadowofdarkness + E:V:A bouncing ideas and opinons imo is helpful and great, and aided in my thought process for getting things done. I will post my findings and how I went about doing everything later on when I have sorted everything all out.

I feel like Dr.House from the TV show right now, pushing hard and going balls to the wall on a theory ftw! rofl.

[Sony Xperia P, U, Sola, Go] BigPhil:
Have you ever wondered how an EP800 compares to an EP850, or an iPad charger? I have. Reading the comments on the forum there is a lot of subjective opinion, but little in the way of facts. With this in mind I decided to make a little app to measure how long it takes the phone to charge from 20% to 80%.

20% was chosen as the start because readings below this have a high uncertainty

80% was the ceiling because the Xperia shows down charging somewhere around 90% to protect the battery.

I wanted to ensure I was measuring the charger at its peak output.

So far I have done 3 runs:

EP800 (rated 850ma) with normal USB cable, 8845 seconds (est 427ma)

HTC B250 (rated 1000ma) with normal USB cable, 7910 seconds (est 477ma)

Unbranded (rated 1500ma) with "data" cable 3120 seconds (est 1211ma)

My current suspicion is that the charger is not as important as we have previously believed, it could be all about the cable. I will run some more tests over the next week using the same charger with different cables.

In the meantime, if anyone wants to give it a go, my app is available here

https://play.google.com/store/apps/details?id=com.vexedbadger.chargertimer

(once Google gets around to approving it)

and my latest results are here

http://vexedbadger.com/?page_id=97

But I will keep this thread updated until I reach a satisfactory conclusion.

I am also eagerly anticipating the EP851. I wonder just how good its boost charge feature is. Could it simply be a normal 2A charger with pins 2 and 3 bridged?

If you do give the app a try, post your results here.

-----------------------------------------------------

For newcomers to this thread I believe I have made an important discovery. I ran a test using a HTC B250 1A charger. I did it first using a normal USB cable. I then repeated it using a USB charge cable (2 wires, no data lines) and got these results

Data Cable, 7910 seconds, est 477 ma

Charge Cable, 3530 seconds, est 1071ma

In other words the cable you chose to run between your charger and the phone is absolutely critical in determining the charge speed. Here I have observed over a 100% speed increase.

Using the supplied EP800 (850ma)

Data Cable, 8845 seconds, est 417ma

Charge Cable, 5170 seconds, est 731ma

Again, a huge difference.

Oh, and the BlackBerry Playbook charger is a beast.
[Sony Xperia P, U, Sola, Go] BigPhil:
I have just done a run with the BlackBerry Playbook charger HDW 34625 (2000ma).

20-80 in 2875 seconds. That means approx 1314ma output. An estimated 0-100 in 1hour 20 minutes.

I have a new charger of choice : )
[Sony Xperia P, U, Sola, Go] LahiruRD:
Nice find, but is it good to charge the battery like that ? :rolleyes:
[Sony Xperia P, U, Sola, Go] Scratchling:
I suspect you're correct OP.

I charge mine with a 1A iPod charger with an x10 cable + 8M Extension cable(sockets only on one side of the room), with that charging is pretty slow. Tried it without the extension but it wasnt noticeably faster. Then one time I used a 15cm USB Micro cable from an unknown device on the front USB port of my desktop(500ma maybe, probably less) and it was insanely fast.

So yeah, think its the cable.
[Sony Xperia P, U, Sola, Go] BigPhil:
My guess is that Sony know a thing or two about batteries. They control the amount of charge passed to the battery. A very conscious decision is made at 90% to reduce the power flow to the battery. I am happy to chuck as much power as I can at it.

Also remember that Sony are about to release the EP851, a high speed charger.
[Sony Xperia P, U, Sola, Go] defsix:
If I remember correctly if you connect only the power cables within a USB cable the maximum you will get from most devices is 500ma. If you connect all 4 cables as a regular USB data cable, the 2 devices communicate and then the phone will ask for maximum current from the USB host. This could be several amps. This is why there is a variations in charging times. Try several different cable on the same port, then try them all again charging from different hosts, ie. OEM USB charger, computer usb port, other USB chargers.
[Sony Xperia P, U, Sola, Go] BigPhil:
I think you are close top the answer there. The USB 2.0 spec says 500ma per port. This spec was written long before charging smartphones via generic USB cables became the norm. Some manufacturers now offer high ampage ports on the motherboards. I know Apple does, my aBit one does and a few gigabit ones do.

The phone tries to detect if it is being charged from a computer USB port where it is capped at 500ma, or from a power supply that supports more than this. There are two conventions that I know of. Apple puts a resistor between pins 2 and 3 (the data pins). IF this resistor is present hen the device charges at full power. HTC (and a few others) rely solely on pins 2 and 3 being bridged. I think this is the USB standard as well. Some batter apps will tell you if the detected charger is in AC (high ampage) or USB (capped) charge mode. The speed difference is pretty dramatic.

Some cables come with pins 2 and 3 pre-bridged. They are no good for syncing but great for charging. I am running some tests with one now.
[Sony Xperia P, U, Sola, Go] shmoejoe:
Interesting app, I have a bunch of random USB chargers and such floating around. I use as my standard charger the 850, but I have wondered if I can get better charge from the piles of other chargers floating around.

I also have a BlackBerry bold charger (direct connection to phone via fixed USB cable) do you think that could perform better? I guess I will test it out first.

Thanks again for your useful apps! I used the nfc one and love it :-)
[Sony Xperia P, U, Sola, Go] richteralan:
I wonder why no smartphone now uses USB3.0

Allows maximum 5A and 1.5A when communicating+charging.
[Sony Xperia P, U, Sola, Go] krabappel2548:
Yes, I'm asking the same question :p

I'd love to charge my XS really fast via my USB 3.0 port :)
[Sony Xperia P, U, Sola, Go] Pezo:
5 Amps? Wow, that would be 25W put into a battery so you have a smoke machine as well ;-)

Multi-purpose charger
[Sony Xperia P, U, Sola, Go] richteralan:
yeah 5A maximum....

I think 1.5A~2A is more than enough for now comparing the mere 500mA USB2.0 provides.
[Sony Xperia P, U, Sola, Go] BigPhil:
I have a usb3 pci card on order. I will post some test results when it does, but that will probably be June. In the meantime I am seeing a very noticeable difference using a charge cable. To the poster with the blackberry charger, I think that will leave your Sony charger standing
[Sony Xperia P, U, Sola, Go] krabappel2548:
I have a USB 3.0 port, will do some tests on charging time between my USB 3.0 and USB 2.0 port ;)

Will post the results as soon as I have them :)
[Sony Xperia P, U, Sola, Go] BigPhil:
I have just ran a test using my HTC 250 with a charge cable. THis is a charger I have previously tested with a normal data cable

In other words the cable you chose to run between your charger and the phone is absolutely critical in determining the charge speed. Here I have observed over a 100% speed increase. Will update the first post with these findings.
[Sony Xperia P, U, Sola, Go] Scratchling:
XS in for repair but gonna do this with my x10 now for ****s and giggles.
[Sony Xperia P, U, Sola, Go] Efe64:
5 Amps?

U mean volts...

Usb 3.0 is max 900mA = 0.9 Amps.
[Sony Xperia P, U, Sola, Go] richteralan:
Battery Charging Specification 1.2[12]: released in December 2010. Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A.
[Sony Xperia P, U, Sola, Go] FenrirMX:
So having a current up to 1.5 A or maximum current of 5A, which one is it?

My guess is that the second one meant volts.
[Sony Xperia P, U, Sola, Go] richteralan:
No. The second one means 5A, if you bothered to read the specification whitepaper.

And my post explains clearly the difference between 1.5A and 5A current:

1.5A for "UNCONFIGURED DEVICES", and "HIGH SPEED COMMUNICATION WHILE HAVING A CURRENT UP TO 1.5A"

5A is the MAXIMUM ALLOWED CURRENT.
[Sony Xperia P, U, Sola, Go] hamidych:
LOL :D I am a bad person, after the second page, was waiting for somebody asking if it is possible to replace a battery in XPERIA :D

Seriously guys, I have weak knowledge abut how the battery charges, I mean about the physical process... Are you sure you are not harming the battery when charging it with unbranded cables / chargers?

Can anyone tell that it is safe to charge your phone with anything, and explain why?
[Sony Xperia P, U, Sola, Go] Pezo:
An attempt to un-scare people from third-party chargers...

The only thing a charger does is take the mains voltage and transform it into 5V direct current.

The only difference is the ripple on the output voltage (the alternating part resulting from the transformation, I can explain that in more detail if you like), the maximum current that it can deliver and maybe some kind of communication with the device to tell it how much current it can take (for example a resistor between the data lines).

The ripple doesn't need to concern you, as the phone also has capacitors that filter almost all of it out.

The maximum current is only of concern in that it limits the maximum rate the phone is charging to a lower level (a 500mA charger cannot supply 1A). If a charger could, for example, supply 10A your phone would still only charge with maybe 1.5A, because the charging regulator inside the phone limits the current into the battery.

If the charger does communicate with the device, fine, if it does not it will simply limit the current supplied to the phone.

Of course I'm not saying any third party charger is good for your phone, it could for example supply 7V instead of 5V, possibly ruining the phone. But I think the majority of chargers are pretty safe, otherwise they wouldn't sell.
[Sony Xperia P, U, Sola, Go] hamidych:
Thanx a lot for the explanation. I have one more question: if we are charging the phone not from a charger device, but from a USB out - PC / Car / etc. is there anything to worry about? If this is a USB out it always gives 5V output?
[Sony Xperia P, U, Sola, Go] Pezo:
For car chargers the same holds true, the primary power source is just another one.

As for a PC, the only possibility that comes to my mind that the voltage would differ is that the power supply of the PC itself was malfunctioning.

But I think you would notice that, with all the smoke coming out and such :-P
[Sony Xperia P, U, Sola, Go] hamidych:
Got it.

Any test results on the USB 3.0?
[Sony Xperia P, U, Sola, Go] BigPhil:
Hi Pezo,

You obviously know quite a bit about these things. Do you mind commenting on a statement I made in a different thread, basically

I am sure I am correct with this statement, but second opinions never hurt.

[Sony Xperia P, U, Sola, Go] biolante:
Hi there,

It is l very nice and interesting finding you did and I thank you for that.

I would like to ask, however, for a tip how to distinguish the data and the charge wires from each other.

I saw the theory about puns and etc. but how could I know what is the wire which I am holding now :confused:? Could I see the pins inside the wire by just looking at it :)? And where usually I can find a charge wire (2pin if I understand correctly)?

Forgive my questions if they are too simple.

Thank you in advance for the answer.

Cheers

TT
[Sony Xperia P, U, Sola, Go] defsix:
http://www.pinouts.ru for the pinout. Generally the red and black are power. The remaining 2, usually green and White are the data. Sometimes the inclusion or exclusion of the braided earthing around the the cable can have an effect also.
[Sony Xperia P, U, Sola, Go] BigPhil:
I would love to be able to give you a definitive answer.

My charge cable was labelled "Charge Cable". Tellingly it looked like speaker wire, two distinct cores to the cable. Likewise the BlackBerry obviously has just two wires.

You could always sacrifice a normal USB cable, open it up and join the data wires.

For my car charger I dismantled the charger itself and put a blob of solder on the USB out port, joining pins 2 and 3. Now any cable I use is treated as a card charger. I cant bring myself to try this on a mains charger. I have a bit of a fear of messing with 240V AC current...
[Sony Xperia P, U, Sola, Go] Pezo:
I only heard about the charger and non charger cables here at the forum, but it seems reasonable to me. I haven't looked into it yet as I use the Sony charger and cable most of the time, but I'm planning to measure the current input myself with different cables (the app doesn't really work for me).

I wouldn't expect a phone to pull 6A, but a tablet may.
[Sony Xperia P, U, Sola, Go] BigPhil:
Just ran a test on the EP800 with a charge cable. 20-80 in 5170 seconds, estimated output 731ma. Thats nearly 40% more than with a data cable (8845s, 417ma).

The more of these tests I run, the more I think every Xperia S owner should have a Playbook charger...

Gonna play with the iPad charger next. I suspect it will be disappointing as Apple dont seem to play by the same rules as everyone else.
[Sony Xperia P, U, Sola, Go] Scratchling:
Using an ipod charger in tests atm, its shít alright.
[Sony Xperia P, U, Sola, Go] jonmorris:
I've been using an HP Touchpad charger (5.3V 2A) and it seems fine. This is also with the USB cable supplied with the Touchpad, which I presume is designed to fast charge.

Will run the app and do a proper speed test, when the battery runs out.
[Sony Xperia P, U, Sola, Go] Scratchling:
1251mA	Ep800	850	EC600L

1379mA	Ep800	850	EC600L

Is my x10 throwing the test, is this a bug with the app, or is the rating total bs?

UPDATE:

This should be made clear in the app itself Phil.
[Sony Xperia P, U, Sola, Go] krabappel2548:

Sorry I don't have results of USB3.0 yet, something interrupted the test..
[Sony Xperia P, U, Sola, Go] Pezo:
I don't have tests with the app, but I charged from two different USB 3.0 ports on different computers and it's definitely not faster than standard USB.

My guess is that 1.5/5A have to be negotiated with the host and that that's part of the USB 3.0 protocol.
[Sony Xperia P, U, Sola, Go] krabappel2548:
Ok, thanks for the info, as a dev I can't leave my device alone for more then 15min so it's nice to hear someone had already tried USB3.0 :)
[Sony Xperia P, U, Sola, Go] BigPhil:
Are you sure you used an iPad charger? I have only ever seen them rated at 2.1A (10W). I have just run a test with my iPad charger (2.1A) using a USB charge cable.

4315 seconds, approx 879ma

This is my first genuinely surprising result. Previously chargers have either worked at a bit under capacity (due to the phone being on) or around 500ma. This is behaving like a 1A charger. I wonder if the charger itself has a cap for non-apple devices? As always, Apple is a mystery.

This test shows again that if you are using a wall plug to charge your phone, you should be using a dedicated charge cable, not a data cable. Now if only I could find somewhere that sold them*...

* I have a few I think will work being shipped from dealextreme at the moment. Will test them the day they arrive.
[Sony Xperia P, U, Sola, Go] mrsatan:
Is the Sony ECL600 not a charge cable then?
[Sony Xperia P, U, Sola, Go] BigPhil:
Is that the one that comes with the phone? If it is, or you can use it to sync with a computer then no. From my limited testing (about 10 permutations) you will get a much faster charge time with a different cable. I found that the one that came with my kadigi dock works great, as does the orange tipped one built into the playbook charger.
[Sony Xperia P, U, Sola, Go] mrsatan:
Thanks Ill have to pick up a Kidigi dock then when I get my new Xperia S back. Not sure if I can find a better price here in america then 22 dollars which i guess isnt too bad.
[Sony Xperia P, U, Sola, Go] Scratchling:
Yes

Ok, maybe its not then. The charger is 3rd party and its 500mA/1200mA(two separate ports). I assumed that was ipod+iphone / ipad but maybe its ipod / iphone but no ipad.

Yes, its the one that comes with the phone, L-shaped jack.
[Sony Xperia P, U, Sola, Go] BigPhil:
There is a chap in the uk selling Timri branded ones for 9.90. I have 2 of them now. If the dock you want has the same accessories as mine, its a bargain at 22 bucks. The charger itself performs like an ep850
[Sony Xperia P, U, Sola, Go] BigPhil:
A quick test has proved me wrong. I did the original test with a different data cable. Repeating it with the Sony one game a 5045 and an output estimate of 749ma.

I guess I should use the genuine cable to test a few of the other chargers.
[Sony Xperia P, U, Sola, Go] jonmorris:
Can anyone here identify the right cable to charge with?

I've found in a drawer a Sony Ericsson cable (still with tag on it) marked EC450. I presume it's a data cable (it appears to be fused at both ends) but wonder if it also allows faster charging?

I've picked up so many microUSB cables over the last couple of years, I'm at the point where I'd like to ditch the cables that don't fast charge and just keep those that do/can.
[Sony Xperia P, U, Sola, Go] mrsatan:
So the genuine cable is working ok or not. Let us know.
[Sony Xperia P, U, Sola, Go] BigPhil:
Works fine with the ep800. Sorry for amy false alarm.

I'm really sorry to hear that. I only have the one device to test it with.

Did you use the standard settings (min:20 - max:80 - battery 1750mah)? Did it tell you how long the charge time actually took?

I did have a bug in v1.1 I think whereby at the end of the run if you rotated the phone it would determine that an entire charge cycle had just completed in the poll time (5 seconds) and rate the charger at 300A or so. I thought I fixed this in 2.0.

On a side note, that app now has 5800 downloads! I was expecting about 30.
