[Q] Kernel / Rom that supports USB fast charge? - Galaxy Note 10.1 Q&A, Help & Troubleshooting

I have looked in both development sections but have yet to find a kernel / rom that supports fast charge for the Note 10.1; The main reason I really want this feature is because I ran across a great deal on a 16,000mah battery bank. I can plug the note into any one of the USB ports on the bank but get the dreaded Xbattery symbol. Would be nice to see how long I could run the note off that bank as an "extended" battery.
Edit: Before anyone ask, the battery is capable of 2.5 amp output on the usb port(s), my local RadioShack had it on clearance for $25.00

You could turn off the tablet in order to use the port, but I got the feeling you are using this while charging , no?
To solve your "x" issue , get the PWR+ accessory from eBay since it has free shipping and its a bit cheaper. This will end the "x" on the battery icon as it has for my laptop. Not only will you be able to charge with that battery of yours, you will be able to do so with any USB port you encounter, and it comes in handy for that reason.
Well on your pursuits towards a fast charging kernel , there is an existing deal for the Galaxy Nexus that is a patch towards the fast charging mechanism you want. Perhaps a port could be created of the kernel patch in order for it to work with the Note 10.1, I dunno. I'm not much of a programmer myself, but I wish I coud take a crack at it if it means to charge faster because of its potential use.

Thanks for the info, and you are correct about wanting to use the tablet while it's connected to that battery. Kind of using it as an extended battery instead of just recharging it. I will look into that PWR+ eBay thing. Oh I might metnion I did try and build this: http://forum.xda-developers.com/showthread.php?t=1675042 but it did not work. (Still had the XBattery).
Edit: Ordered the PWR+ Thanks

No problem. Hope someone does do the fast charging deal.

Has anyone looked into building a kernel with USB fast charging yet?

Anyone ever tried this?

As a external powersupply, it says that the capacity is 12000 MAh so enough for 12 charges, or do I make a mistake somewhere?
It seems that a miniUSB connection is suplied whit it so I shouldn't now why it wouldn't do the job and the size is (for me) acceptable with almost 3x3x0,5 inch, I mean for tracking at locations whitout electricity it could keep your GPS going.

Tried what? No link? Product name? Anything?
USB Charging
Not sure about how many times it would charge your diamond...but it looks like it has a Female USB connector so any USB cable could be plugged into it to charge ANY device...if your device allows USB charging that is.
Best regards

12,000Mah!?!
Doubt it, must have been some serious squashing to get that much juice in there!
My laptop battery is twice the size of that and has 5100Mah capacity. Would be great to be able to charge it from that thing!
Ill just ordered
I just ordered the battery and as soon as it arrives I will write a review of it.
Willem
I don't think it'll work. There were some user reviews on similar charger saying it won't charge their ppc's through USB.

your laptop battery is also higher voltage, probably 12V.
think of the AA-size NiMh cells, the best ones are 1.2V 2800mAh.. two of those aren't close to the size of a laptop battery and yet they have higher mAh.
but you're right, 12000 mAh in that thing is utterly impossible
edit; anyone tried this?
http://www.instructables.com/id/Portable-USB-Charger-Version-2.0/
edit again; this seems more like a real product, but it's larger than the actual diamond is. not too convenient.
http://www.proporta.com/F02/PPF02P05.php?t_id=4125&t_mode=des
late edit; if a computer usb connection is too weak to charge the diamond, shouldn't it be possible to solder a cable that connects the diamond to two usb ports simultaneously?

I have one of those crummy double A chargers from energiser i got from a friend and using the mini usb included with it, the phone does indeed charge but only when its off. When its on the power its using makes the battery pack redundant, but thats for my crappy charger. I think this should work, and if not it would work for another phone or device.

I made a small calculation my 2000MAh is in size 40X35X10mm =14000mm3
The size of the 12000MAh is 74,93X74,93X14,986mm=84138,9704314
84138,9704314/14000=6,0099264593857142857142857142857
6,0099264593857142857142857142857 X 2000MAH (which is the size of my battery)=12019,85291877142857142857142857
Acoording this caluculation it should be physical possible I just don't now how much cell it has and neather or by just doubling the size you can double the capacity aswell.

That's true for another Li-Io-charger which I bought from DealExtreme. From what I can see, they don't check their inventory very thoroughly for function and quality. Most of the stuff is just fine, but there is also some junk - and my Li-Io-charger was among it.
Since they advertise it only for the PSP, I can imagine that it will not offer the high current to charge a working Touch Diamond.
Have fun!

Do you now howmuch is the power use off a PSP?
I do agree with you that not everything is made off gold what they sell at DealExtreme, I also bought already some useless stuff from them but this item should be a verry big mistake from them cause there are rumors at there site about this item, I even doubt about it aswell and thats why I cancelled the order but after I made the calculation I am in doubt again.
I travell a lot and one off the country's which I visit a lot is Brasil and for such a country whit the infrastructure availleble (or just NOT availleble)
If you make a long bus journey or plaintrip (Brasil is at least 12 hours where in you have nothing to do) or even in the bush or just tracking such a item could be ideal.
Willem
After a email with my doubts Deal extreme send me the folowing message, in a previous message Itould them about the doubts and asked them to check or the ordered battery is realy 12000 mAh, they have checek it with the suplyer which confirmed the capacity of the battery, as soon it arives I will post a review of it, which maid take a few days cause I want to test how many times I can charge my phone with both a 2000mAh and the original 900mAh battery.
Dear Willem ,
Thank you for your reply.
Item 19086 was shipped on 12/31/2008 after checking. The supplier informed that it is 12000mAh, we will keep the ticket open, please feel free to send the news once you got it?
Thanks a lot.

Received the battery
Received today the battery but the Mini USB doesn't fit at my Diamond the output is 5V 700mA anyone now or this is enough to use and charge my Diamond at the same time cause if this is possible I will try to make a custom cable.
Someone can tell me aswell which contacts are used to charge a phone on mini USB, as you can see it seems the contacts are about the same there is just a diference at the outside off the connector, the main outside connector is a standard plug but I don't now or there are connectors at the market to make from the standard connection a mini USB
The connector fits at my dock and is able to charge my phone so in case of emergency I can charge the extra battery that way
Here some pictures
http://84.104.255.96/connector/index.html
Well I tested the battery and the outcome is disapointing, could charge my 2000mAh battery once complete so I gues all the critics about it where right, I have contacted Deal Extreem but untill now no answer.

Alternative to Spare Batteries

I like a lot of people use my phone very heavily yet I don't have an opportunity to plug my phone into an AC charger until I return home. A great remedy to the problem is this handly little AA charger.
http://www.igo.com/accessories/powerxtender-charger/invt/ps002640004/
The reason I like it so much is because cheap portable battery packs usually pack under 1000mah of power. Thats not even enough to give you 1 full charge. And the more expensive 2000mah+ packs are often on the large side and well... expensive lol. On the other hand this little bugger is cheap and small enough to sit in my pocket without being a bother. What I find is the best part of it is the fact that you can choose what kind of AA batteries you put into it. I opted for Energizer rechargeable which are rated at 2450mah EACH for a total of 4900mah of power. Thats the equivalent of 3 G2x batteries. Keep 2 more batteries in your backpack/desk/purse thats an additional 4900mah. If that can't get you through the day you have more than just phone issues
Originally bought it for my Vibrant but quickly found it was awkward because the the product doesnt come with a cable adapter. This meant it was hanging and putting much strain on the usb port of the phone. Out of fear of breaking it I stopped using it. However since the G2x charges from the bottom there is absolutely no problem espcially seeing as I bought a 20cm micro usb extension cable so that the charger can sit in my lap or on a table while using the phone.
Just thought I'd share this since we can't get legit replacement batteries yet and even when they do become available they will cost a pretty penny. Got mine from Staples but they can be had on amazon also along with the usb extension able and rechargeable batteries.
This one works very well, too:
Well I'm a new member, so not allowed to post outside link. Therefore goto
Amazon
Duracell Instant USB Charger with Lithium ion battery
Pick the very first one
You don't need to by batteries or an extra charger. You can recharge it via your G2x power supply or any computer.
This was my favorite (coming from g1)
Too bad theres no new version for the micro usb's now..

This can be added on, though it wouldn't be very convenient since its a slide in/out connector

I almost bought one of those until I saw how low the capacity on it is. Looks tiny though which is nice.
J&R has Veho 5Ah external battery for $35 and I have 2 of them.
Just use regular microUSB cable to charge the phone and leave the original cable secure.
I'm thinking about getting the i-up 13,200mAh pack.

They have a bigger version for 32$ as well. The 22$ version gives me a full charge from around 30%.
Just received my Pebble XT 5000mah pack. Won't be able to put it through its paces till next tuesday. Upon first impression, i think im in love with this thing already. its small enough to sit in pocket without having much presence. extremely lightweight. and the cord is long enough to be able to have the charger in your pocket and phone in hand (thank you lg for putting the usb port at the bottom). All info I have read indicated that it really does output 5000mAh of power so even a heavy user such as myself will have no problem getting through a full day of use.
Just wondering how everyone's batterys are working out for them?
Also how many full charges did you get?
Also any likes or dislikes of product they decided to buy?

That looks like something that might be good out camping or something where you needed to charge your phone without touching it. But I would figure actually picking it up and putting that much weight on he usb port a very bad idea... This should come with a extension cord to charge while using, even texting or something would be pretty difficult to hold both...

ImaxPower IMP500 (5000mAh) External Battery
I've used an IMP500 Rechargeable (5000mAh) external battery pack for a few years with great sucess. They make them as large as 11000mAh (or more?) and even have solar-rechargeable options. Just take a look at New Trent or other similar products on Amazon or eBay.
The best part about the IMP series is that they have multiple adapters for iPhones, mini/micro USB, PSP, DS, and other devices so you can charge your phone and anything else you might be carrying around with you.
Link to NewTrent for info on models
I'd recommend buying elsewhere because you can find them for 30-50%+ off.

External USB Battery Charger for HTC Desire Battery

Hi All,
Couldn't find this posted before so wondered if anyone could recommend a USB Battery Charger to change the batt from my Desire without the phone. I have a spare and going on travels want to be able to just leave the battery charging on its own and not use the phone all the time.
Ive seen quite a few on ebay and some look really dodgy with adjustable charging pins etc whereas others are ridiculously cheap and i can only imagine will ruin my battery.
Key points are it should be small, light, USB powered and whilst I accept it will not charge as good/full as through the phone - not to knacker my batt completely.
Cheers for any help.

I have been looking for the same thing and found a battery pack on Amazon for £25, manufactured by New Trent it has a 5000mAh battery in it and can recharge your phone at least 3 times.
I ordered the dual output version on Sunday, so hope to get it and try it out in a couple of days.
Using a Veho pebble here, works great
would be nice for a faster charge though, it seems a bit slow for 750ma

I've got one of those. It's really good, one of the outputs is 1A so charges up really quickly.
My only criticism is the on/off button is easily pressed by accident, but that's really looking for problems. Oh and it would have been nice if the usb socket to charge it was a microusb one so I could use the same lead as the phone.
It's a good battery pack.
It certainly sounds like it is going to be good.
With regards to charging the pack itself, does it come with a USB to mini USB charging lead?

Mine didnt come with any charger or leads but as I have a box full of that stuff it wasn't an issue.
Edit: I'm an idiot. It came with a lead with a selection of interchangable tips to fit most phones.
I forgot as this is now also living at the bottom of my tangled box of leads.
Thanks for the replies guys.
Yeah i actually had one of those external battery packs (5000mah) but found that you could not even get 2 full charges out of it and therefore not worth the extra weight/charge time.
Basically its misleading because the voltage of the battery is different to you phone battery and it need to be upscaled or something - there are quite alot of posts about it. Let us know if you manage to get 3 charges though - that would be good.
But anyone used external chargers for the a spare phone battery?

On Charge Draining Like No Tomorow

I Have A Samsung Galaxy Note 10.1 I Got It About 8 Months Ago I've Used The Samsung Official Charging "Cable" For Most Of That 8 Months but about 2 months ago the cable became loose at the Samsung cable to tablet end exposing the wires so I was careful with it and put it away and used my friends official cable then he needed it back so I went off and brought a generic cheep cable for $3.50 So all was good there but slowly I've noticed my battery going crazy like taking longer to charge "2 Days to full" and things like it discharging by 2% when I am on Google while its on charge and when its off charge playing 1 game uses almost all the battery.
so being the awesome soldier that I am I made myself a 5cm cable hoping that the long cable I was using had something to do with it but still I had the problems listed above so I did some Googleing and maybe a 2.5A charger would be helpful But its not recommended. also I sent a email to Samsung and being the "SUPER HELPFULL COMPANY THAT THEY ARE" has not responded to my emails in the past week's Also I Spoke To A live chat person thing and Being "Soo Helpful! " Said that its a hardware fault and I need to take it into a Samsung repair place and fork out $100+ Bucks to get it fixed "HELL NO AnT No BoDy GoT TiMe FoR ThAt" so I didn't go to Samsung to get it repaired so I want to know if any of you guys out there have any idea to fix this problem im having because its so hard to do anything.
Just Checking my emails while its on charge uses %4, On Google for like 5 mins Uses 2%, Playing A Game For 30Mins Uses Well Almost Flattens It, And Watching Some YouTube Takes It Down To 0% And Then Shuts Down( I Watch Lost Of Videos) All This While Its On Charge
At The Moment How Im Copeing Is I Carry Arrount An Inverter And A 12V Battery To Keep It Charging
The SGN 10.1 charging cable is a specially designed cable to deliver 2.1A 5V to the device.
Most "cheap" cable on the market can only deliver 0.5A - 1A 5V when used to charge SGN 10.1
You should find the correct cable specifically built for SGN 10.1

Thanks but how can a cable make all the difference i managed to charge off my old one its just got exposed wires and it still drains when i use it
Are you certain that the battery is actually draining that fast and not simply misreporting it in the UI?
I had a similar problem where the battery didn't seem to last but I eventually noticed that a reboot would completely change the amount of charge remaining, sometimes by as much as 20%. I cleared the battery stats and is been fine since.

Well actually when-ever I turn it off it doesent charge much and if I restart it the battery stays the same but over the last few days ive noticed something weird when its on chatge and I play a game it drops about 20-30% but when its not on charge and on battery it drops by about 5-6% could the charger be draining it? also I have a new new cable its generic (IM NOT PAYING $60 FOR A CHARGER CABLE) and there is no difference still does the weird charging thing also I tried the old cable and still does the same thing the olny thing wrong with the old cable is that the wires where exposed so I dident want to use it just incase it broke

If you don't want an OEM cable and charger you can buy a crap chinese one. But as you and many others have discovered - they suck. This is one of the biggest complaints I have always heard about Samsung.
The solution, and the only on that I have found that works 100% of the time is to buy a replacement from Samsung. Period. Nothing else works like the OEM parts because they aren't OEM parts.

The wiring on the OEM cable is somehow different than most cheap cable.
I'm experimenting by buying a 3M long "cheap" N8000 cable on eBay, may be it can help (delivery time is VERY long )

What ROM are you using?
Stock or Custom?
Rooted or not?
If you are Rooted (Stock or Custom) you can use Battery Calibration app to erase batterystats.bin to calibrate your battery percentage which are needed if you change ROM.

$60 just for a cable? Really? I live in the UK and I bought a whole new charger (official Samsung one, too, including a cable) for about £12 on amazon. Just go to Amazon and replace the charger, it sounds like it'll be cheaper than just the cable (probably 15-20 USD or maybe 30-35 AUD, I'm not sure what the rate is and where you live ) and if it is a charger related issue that'll be fixed too.
Just so you know, I bought the 'travel charger' (the white one) and it works perfectly. Supplies the same current and voltage, and it's a smaller unit, and cheaper! I'd just look into getting one of those.

USB type C magnetic charger

Does anyone know/own a magnetic USB type C charger for the s8+ that feature quick charge.
I want to know how well they hold up before getting one.
Dont hold your breath. If they are anything like the ones for the s7 edge they were crap and very cheap made. Easily disconnects from the cable. Didnt always fast charge. Need to ensure it attaches right if not it may not charge at all or charge at normal speed. Would not buy another ever again.
https://www.amazon.com/gp/aw/s/ref=...+fast+charge&sprefix=magnetic+usb+type+c+fast
Can't vouch if any of them ACTUALLY fast charge. A customer does claim out works on an S8 though.
Thanks for the feedback guys. I've reviewed numerous ones on Amazon and most of them are mixed. I'll keep on digging.
I'll post a link If I find something decent that gets the job done.
Please keep us updated!
Will do. I know the phone is still pretty new. So I'll give developers of the mag chargers for the s8 a little more time.
I'd like to find one so that I could just leave it connected and not have to worry about breaking my charging port..
