So, I don't know if this is just my device or maybe already known. I don't see it here(or google) so I am going to post this so others can find this info faster than the 2hrs it took me.
Some Li-Ion batteries have a low max charge rate. Meaning you cant "over-current"(mA "Milli-Amps" or A "Amps") them too much(saves life). Well my Razr just showed me this. This can allow you to charge the battery faster if you have one that is tolerant of the "over-current".
Apparently maximum for the Droid RAZR is somewhere between 850mA and 1000mA
Tried using an HTC @ 1A and no joy.. wont charge.. actually says charging.. but the battery seems to have flipped the switch to not charge; and just continues to discharge normally; even the hidden status(dial *#*#4636#*#*) says charging but obviously not! Tried different HTC models and different cables. I am now only using my Moto supplied cable.
Even after it was dead. It would show the charging screen @ 0% and the light would be red. Stating that you cant turn it on cause there is not enough juice to finish boot. It would never go Green no matter how long I waited(10-15 minutes) usually only takes 5 minutes.
Found my OG Droid charger; remembering that it was lower than 1A. It actually is 5v 850mA. Charging away!
Remember the stock charger is rate @ 5v 750mA - this means you can probably use chargers from 700ish to maybe 900ish mA. I cannot confirm these estimates. Anyone else seen any other rates work?
Hope this helps someone down the road. I know it would have helped me!
MODS - Please, if this is wrong info please DO NOT HESITATE to notify me/remove/edit my post. I just want the right info somewhere, cause it was not well documented anywhere i searched via google.
Also - Thinking more on the subject - this could be the "Authorized Charger" bull that Moto likes to put on its devices i.e. The RAZR flip-phone was notoriuosly bad about this. Even my old nextel "beep beep" had this problem with OEM chargers. Had to spend $15+ on the official one. Again - if this info is wrong in ANY way please fix it or remove it.
use official 850mA charger and be happy. Motorola also confirmed using 1A chargers without any problems but any ways original ones are recommended.
Brilliant, my problem now makes sense!
Couple of questions: What does this mean to charging via USB instead of mains? Is it the plug or the cable that is rated to a certain ampage?
One more question. I found another usb plug rated to 300mA. I presume using this will just mean the phone charges slower? It won't have any negative effect on the battery?

Just adding my experience... Have been using an iphone wall charger w/ the usb jack on it and the supplied motorola cable. Its listed as 1000Mah. Battery Monitor Widget shows it charging around 945Mah. Doesn't get hot, charges like a bat out of hell. Down side is phone is about 60% unresponsive during the charge.
Found a little info on this. Apparently different cables, when plugged in, short different contacts to let the device know what it's plugged in to. Resistors change the current. Audio out can tell if it's plugged into a dock versus USB versus wall charger. The Verizon replacement didn't work for me, but an hard incredible one did. They both charged but only the htc recognized computer connections

My stock Razr wall charger is 750mA. I use a 1000mA car charger and it works fine - doesn't get hot and charges faster.
But sometimes you do have to be careful. I had a friend who's noob mother fried her Bionic with a charger that was too many mA for it to handle.

strange... my stock charger's rated 850mA.. maybe because i use international GSM version of RAZR.. but it charge just fine..
but even i tried charge it with blackberry's 700 mA charger or my ipod touch 1000mA charger it both charge just fine.. and it feels like the 1000mA charge slightly faster..
too bad i broke my old nokia n900 1200 mA charger..
I'm using an HTC 1A charger: the RAZR doesn't become hot while charging and it's charging faster.
The limit is 1A anyway.

dang! so i guess nokia 1200mA charger won't be any good then..
thanks for the info though.. i was thinking of getting myself a nokia charger after read this thread..
Ever since my first motorola I've noticed that the stock charger is 5.1 volts.
Charging with other brands always seem to give worse battery life.
My old Rizr only lasted a day when charged from the USB of my computer, but 6-7 days with the original part.
Some of that is apparent with my car charger too, it says it's taking charge, but sometimes it will run backwards with GPS running..
I experience the charger issue last night.
I had low battery when I went to sleep, put the cable in and it said charging.
Came late to work because the phone drained the battery instead of charging. I used a 5V 1.2A charger and its been working great until last night. And I noticed my original charger is 5.1V 850mA for the Razr.
You learn something new every day!

Theoretically, since is a 1.5A charger (or 1500ma) it should charge our device from 0 to 100% in about 1 hour and a half.
OR......
28 percent in just 30 minutes....................that's almost 1% per minute......
I'll get it this Friday and report back. Might as well go pick one up for yourself. You have to use your own USB Cable.... OEM Cable seems highly recommended.
CHEERS!
IF and only if its middle pins are shorted you will get a max of 1 amp charge, not 1.5.
I think just the pins on your cable need to be shorted so if you use your OEM cable that came with the Note then it should work.
OP- Please report back how it works out. Thanks for posting.

As said earlier, this is incorrect. If the pins on the cable are shorted, the cable won't pass data. If the pins on the charger are shorted, any USB cable will allow fast charge.
get a 10 amp charger and it will charge even faster.
Guys dont be stupid. Note wont charger faster than what an 1 amp charger does.
You have to have special kernel mod to get a higher amp charger to charge faster.
edit : if u r spending that money get a genuine hp touchpad charger. its 2amp. At least will be useful for other devices as well

The Xperia Tablet Z is a notoriously slow charger and won't charge over USB (from what I've heard, I don't have mine yet). Does anyone know of a portable charger or power pack that'll work with it?

The Xperia Tablet Z is supplied with a charger that connects to its USB port; so, the XTZ will charge via its USB port.
If you attempt to charge the tablet via a computer's USB port, that port must be capable of supplying enough charging amperes, otherwise, the tablet will not charge. Standard USB 2.0 ports supply up to 500 mA and standard USB 3.0 ports supply up 900 mA, neither of which is truly enough amperes to charge the tablet. USB ports on computers that are specifically designed for charging devices usually supply 1500 mA (1.5 A) or more. Some manufacturers mark these types of USB ports with a lightening bolt symbol.
As for portable chargers, I have not used any except for chargers that fit in my automobile's power plug (cigarette lighter plug).

Any halfway recent (read: last 5 years) USB charger will work with it. Be it the one Sony supplies with the tablet, an iPad charger...or one for the Galaxy Note 2.
USB chargers are standardized, you need a "special" one nowadays about as much as you need a "special" socket for a device with a power plug.
The only difference is that we have weaker and stronger chargers, but this does not limit their usability. If you use a weak charger your device will charge slower, if you use a charger with an higher maximum power as your device needs it will expl nothing bad will happen either, it won't take more from the charger than it can handle.
Personally I bought (since I need the original 1.5A charger for the dock) a 2A Samsung charger for travelling. I think it is the same as the Galaxy Note 2 uses, which you already have.
Oh, and it charges with the 2A one over USB also around 30% faster than with Sonys 1.5A.

Maybe I'm not being clear.
Portable power supply. With a battery. One that puts out enough power to actually use the XTZ while it's charging, even if doing so only keeps the battery the same rather than actually charging it.
Can anyone recommend anything?
I know it uses a standard micro USB connector to charge but I've heard it won't charge from most PCs as they don't put out enough power. My understanding of many portable chargers is that they also don't put out a great deal of power unless specifically designed for laptops and the like. I don't know if the tablet's needs are quite that, but I'm looking for anyone who has experience using a battery pack with it and if anyone has any recommendations.
Or am I being silly and it'll work with anything capable of charging any tablet?
Thanks.

It should. The XTZs battery isn't exactly high capacity as tablets go. The Nexus 10 has a 50% bigger one and the iPad3/4 one is almost twice as large.
The principle of power packs is in the end identical as that of basic USB chargers, even a 500mA one will charge the XTZ, but it will take around 15 hours for that (and around 24+ hours to charge an iPad). It isn't a question of "working", but of "working how fast". But, as said, the XDZ hasn't exactly an huge battery, so if anything it will charge faster than other Tablets.
Assuming you do not use it, that is. It is quite possible to discharge it as fast a 3A/hour if you use maximum screen brightness and CPU intensive tasks. But you can discharge other Tablets faster than you can charge them as well.
So what to use - same principle as with USB chargers, pick any. It does not matter if its power comes from a power plug or batteries. If ti works for one USB device it will work for all. What matters is it's maximum A output. One with 2A should be able to charge the XTZ in 4.5 hours, one with 1.5A in 6 hours, and so on...

The Sony CPF2LS USB Portable Power Supply with 7000 mAh Battery charges at 1.5 amps so it should work for you. I'd post a link to Amazon, but, alas, I can't. It's around 63 bucks.

There is a slew of chargers that will charge it. You can use laptop USB, but like mentioned if you use it while charging it will drain
To solve this problem you simply need to have a portable charger that will put out at least 1.5amp(which is what the tablet charges at if im not mistaken).
So plenty are on amazon or ebay which you should have access to in europe
I use powergen ,they work well and is good quailty. Like either of these will workbigger mah will make the charger simply last longer)

Key thing is to simply look for the amerpage it puts out before you buy, that's how you know if it will charge and use the tablet at the same time. I can sucessfully do both using my car charger(2amp made for iphones) and my Powergen

The thing is this entirely depends how you use it. It is quite possible to use it in such a way that you would need a 3A charger to stop it from discharging. I do not think such one exists nor that the battery can accept such a charge.
So AFAIK a charger (be it a power plug or battery one) which stops it from discharging under all kinds of usage scenarios does not exist.
Therefore there is no answer to you "which charger I should use" question, only that the more A a charger puts out, the more usage scenarios will be covered (as in "will charge tablet while using it that way") by it.
Test how fast the Tablet discharges (without charging it) when you use it the way you plan to while using your charger. That will give you an indicator what kind of power you need. I.e. if it takes 12 hours even only a 0.5A charger will work, if it takes 2 hours you would need a 3A charger, which likely doesn't exists.
Im using an innergie charger that gives 2.1 amps and it charges a little faster than the 1.5a that came with it!

You know that that charger will only charge around 66% of the XTZs battery, though?
(Effective maximum capacity ~4A (see "attrition factor" explained in 2nd review), XTZs battery: 6A)

Charges alot faster so for people with other chargers I should check samsung chargers haha.
Heya,
I've used the Momox iPowerPro+ on my Xperia Tablet Z and no problems
http://shop.brando.com/Momax-8500mA...2-1A-1A-External-Battery_p08658c0191d003.html
Hi everyone,
I have just swapped my Galaxy S3 to a HTC One X+ because I couldn't stand Samsung's Touchwiz, and I love Sense 5. The downside is the charging times on this new phone are pretty laughable!
Now I know different cables can give different currents consistently, but I have three cables (one at work, one in car, one at home) that would all deliver 1000mA to my GS3 and I could go from 10% to 100% in about 90 minutes, about 1% per minute, it was great! Battery life on this phone never degraded so I know 1000mA wasn't damaging at all (all GS3s can take a maximum of 1A).
I've now moved over to the HOX+ and it's taking absolutely forever to charge, between 3-4 hours to charge from low. I simply can't wait this long, it's beyond a joke :crying: I've checked Better Battery Stats and my battery usage is about the same as my GS3 when unplugged (about 4-5% per hour) which is fine, so why the difference in charging times?
On my GS3 I had an app which showed me charging current that was specific to GS3s and was very reliable, but I can't seem to find a reliable app for the HOX+, the one I have is Battery Monitor Widget and it reckons I'm charging @ 330mA and I'm currently at 22%, that can't be right can it?
Here is what my phone is says when charging "Charging (USB)".
In the past hour it's done about 20%.

Erm thats the issue. When you charge using the AC (By cable to the electric socket) it says "Charging(AC)" . This usually takes me from 10-100% in about 90 minutes with the HOX+.
Somehow either you are connecting it to a usb hub (laptop or a computer) which is pretty slow compared to the AC, or your phone is mixing up the AC and USB currents. So an advice, use an electric socket and make sure it says "AC" in the power tab. IF so, check the charging time you should find it similar to that of Samsung.
I also think usb 3.0 is faster in charging than 2.0 ? If you are on a new pc with a new motherboard you should find your sockets 3.0, so don't use a usb hub especially if it says usb 2.0 since it will be pretty slow.
Hi Gand0ur, thanks for the advice.
I should have said before; I never charge via a computer/laptop/USB hub. Only directly into the wall. It is an aftermarket charger but it's a good quality one as it charged my GS3 @ 1A and also my old Sensation charged in about 90 mins.
I've just tried a different cable and still the same outcome. I'll try another wall plug when I get home tonight

That isn't necessarily true. This charger has been the fastest thing to ever charge my HTC Sensation and GS3, and come to think of it my Nexus 7 charges faster with this charger too. As I said earlier, I had an app on the GS3 which showed it was outputting 1000mA (maximum the GS3 allows) and it would charge that phone in around 90 mins. According to the HOX+ app I have I'm only getting 330mA. Whilst I agree that poorer after-market chargers often give dubious results I'm confident that this isn't the charger's fault.
I'll try the a HTC charger when I get home, but the other night I had it on charge with the HTC charger and it didn't seem to move very quickly.
I'll just say what I know from experience with my HOX+: it only seems to be charging in a normal (and pretty fast) way with the original, from the box, charger.
I tried charging it with the charger from a Desire Z - slow; charger from Desire S - slow; a Nokia charger - slow.
I also noticed that while the Desire S or Z can get charged while being used, when using a car charger (a Nokia one), the HOX+ seems to be using more current, and it ultimately dies. It happened this summer, so this might be an issue.

I think you're right! I tried my wife's HTC One S charger last night (because the HOX+ doesn't come with one) and it changed to Charging (AC) for the first time. I have to say this is a massive let down for me, my car charger saved me so many times with my GS3 (for example I drove to Scotland and used GPS all the way, and the phone still charged right up at the same time) I'm not sure I can handle it not being able to cope with other chargers.
I find this extremely frustrating Is there not a hack to get around this with root?
I'm not sure about the Samsung, but the HTC will only go into the fast/AC Charging mode when it see the Data+ and Date- signals shorted on the USB port. This can be designed into the charger, such as the factory HTC wall charger, or you can buy "charging only" cables and then use any USB charger to get your HTC to go into AC charging mode. These charging only cables are tough to find, but amazon does sell them. Keep in mind that the charging only cables will not transfer data at Data+ and Data- are shorted. Once you are in AC charging mode, the phone takes over and determines how fast to charge. At low battery levels (less than 80% or so), the charging rate can be as high as 1000ma/h or the maximum the charger is rated to deliver. If the charger is rated to deliver more than 1000 ma/hr, the most your phone will draw is 1000 ma/hr.
Now there is another variable, the cable itself. Cheap cables sometimes have too much resistance to pass 1000ma/hr and can be the problem as well.
One other issue is the number of knock off chargers and cables out there. Beware of e_ay. You may not be getting what you think you are.
One final note, Apple designs the ipod to look for the Data+ and Data- signals to not be shorted (opposite of HTC and most android manufacturers). So chargers that are designed to charge Apple devices will need the Charging Only cables to charge android devices in the AC charging mode.
So if I didn't confuse myself, hopefully this will answering some charging questions. I've researched this and have tested many chargers and cables.
I recently purchased a wireless charging adapter from http://www.amazon.com/gp/product/B00QMIM6EM/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1. I bought two, one for my alpha (international variant- exynos octa core). One for my wife's alpha (ATT variant quad core snapdragon) my wife's phone is able to charge on my wireless chargers to 100% every time. My phone will charge to 71% and stop. the receiver will show charging but the device will no longer charge. While plugged into the wall my phone will charge 100% so its not a battery issue. I thought it could be an overheating issue as well, however my phone is cool to the touch and even when I turn the phone off to charge it only charges to 78%.
My question is obviously, does anyone know what could be happening?
Is there a security setting im unaware of?
its worth noting that I have upgraded to 5.0.2 firmware through Odin recently.
Thank you for your help. I cant seem to find an answer to my issue on the googs
I have the same issue with SlimPWRcard from fonesalesman.com on 5.0.2.
Did not get the chance to test on 4.4.4 as I just got the phone and flashed the UAE 5.0.2 directly. Might give 4.4.4 a try during the weekend.
Hi all, I have the SlimPWRcard from fonesalesman.com as well. Qi charging has been fine on 4.4.4. On Friday I upgraded to 5.02 and my phone now stops at 69%. Very annoying.
And to add I can charge it to 100% fine through USB.
Any ideas?
---------- Post added at 03:55 PM ---------- Previous post was at 03:06 PM ----------
Also to add, I factory reset the phone this afternoon, and the problem still exists. I am thinking now that if I don't find a solution I will downgrade to 4.4.4.
Maybe in the 5.0.2 they have increasing the charging current, and the wireless charger can not provide that current.
Any way to solve that problem?

I think you are correct about the 'current'.
With 5.02 installed, Qi charging increases the temperature of the phone to the point where I get an error message stating there is a problem with the battery, when I know there is not, and the phone gets quite hot.
Reverted back to 4.4.4 via odin and Qi charging is working fine again.
It would interesting to know if users with the official samsung wireless charging cover get this problem with 5.02. I am using a 3rd party wireless receiver.
I have connected the wireless chargins pads directly to 5v and the phone charged to 100%.
So I was right and in 5.0.2 the charging current was increased and the 3rd party wireless receiver can not provide that current.
Any android developer knows how we can customize the charging current?
I Charging from current usb 4.3v and 4.2v when wireless virtually identical.

Feeding 5v directly to the contacts it as a charge on the usb cable without control. And why then up to 70% is sufficient 4.2v?

The charging circuit needs 5V and not 4.2V.
Both usb cable and wireless charger module supply 5V, but usb cable can drive up to 2A and wireless module only aprox. 500 mA

I used the program Amere. It shows the charge in volts via usb and wireless charging almost the same. eg 4.3v and 4.2v. If anyone has the original charge Samsung. Take a screenshot with this program by 70% and 85%, for example. For what would be found unlike fonesalam.

That value is the voltage of the battery.
And the voltage in a battery is not linear, so 4.2v or 4.3v in the battery may correspond to very different charge states

It is known that the charge samsungovskaya still charging up to 100% (though sometimes problematic). It is necessary to compare the behavior of the SlimPWRcard from fonesalesman.com and original.
PS Sorry for my English as the transfer from googl translate.

Yes that comparison would be interesting.
Would the original charge to 100%?
In the ampere app what is the charging current of each?

Yes original 100% on 5.0.2
I have only SlimPWRcard. Need a holder of the original Samsung

On Ampere app I have 680mA using the original wireless cover (95% battery level).

You can make a few screenshots from the program to analyze and compare.
For example, up to 70% and then 80%
Hi all! (first post on XDA)
I recently bought a SlimPWRcard from fonesalesman and have it installed on my galaxy alpha (SM-G850F) Android 5.0.2 (OTA-update) with the stock "samsung experience". I'm also using the original samsung s-view-case for the Alpha, so I had to rasp the metal studs a bit (on both the SlimPWRcard and the flipcase) to make the SlimPWRcard fit.
I've had the same trouble as everyone else here with the phone charging wirelessly to about 70% and then stopping. When the phone has reached 70% the stand-alone-charger is still on, but the phone isnt accepting charge to the battery.
Today i discovered by accident that if I have the Samsung screensaver "daydream" active AND the s-view flipcase open, then the phone keeps charging above 70%. I've tried this several times now. If I turn off the "daydream" screensaver the phone wont charge above 70% wether I have the s-view-case open or not. If I turn on the screensaver and leave the flip-case open the phone keeps charging. If I have the screensaver on and the flip-case closed the phone doesn't charge.
I have no reasonable explanation for this, but maybe it'll help someone else to figure something out. Maybe the phone draws more juice from the battery when the screen is active and that keeps the battery accepting charge wirelessly?
It also seems that if I keep the screen active (like streaming from Youtube or simply continuously swiping the screen) the phone also keeps charging. However, if I let the screen go black, wait a few seconds for the charging to stop and then activate the screen again, then the charging wont start again. I have to let the phone start to charge and then keep it "active" for the battery to keep charging.
The charging seems to be slower after 70% and the phone gets a bit warm. but I guess the slowness can be attributed to the active screen.
So is this something worth investigating or is it just a fluke with my setup?
I happened or nearly happened to repeat the trick with the screen saver. The truth just once. At the same time nebylo charge indication, but though Meden but it was. Several other attempts have failed. The truth is I do not have a cover.
I have both the SlimPWR card and the official Samsung wireless charging cover, in KitKat both worked just fine, charging up 100%. After the Lollipop Update, only the original cover tends to charge to 100%, not always indeed, sometimes it stops around 95%, but the SlimPWR card stops around 70%. I don't have the displaycover, but i will check the Daydream option above.
