Hi all!
I charged my Xperia Neo with another cable (the one from Kindle reader) and it actually charged it up much faster than with the stock one. I used the official transformer only with a different cable.
I've noticed that with the official set my phone charges aproximately at half the current than with others. So, I get it to charge at around 500mA with original and around 900mA with others (max. current as it depends on SOC - State Of Charge).
Is it any bad for the battery? How bad?
Actually, other devices such as Nexus7 charge at this current. And I believe they all have similar battery technologies.
It is safe, its like using a slow charger and a fast charger concept. The downside is the battery will reach its wear and tear and lessen its life.

It would lessen its life anyways since the battery needs to be charged, wouldn't it? Does it really matter to charge it at a higher current (around 1A)?
I'm no expert on this issue so I think that if Sony designed the transformer and the cable in that way there must be a reason.
Also I noticed that the heat from the battery produced during charging is higher.
- With original transformer/cable: 28ºC peak.
- With original transformer and a different cable: 38ºC peak.
Actually, I think that even wtih 3D games it doesn't reach that temperature.
Last time my phone was charging at higher current and i was doing a phone call it restarted after a while. Not sure if it was due to temperature though, but it might not have been the reason since my phone reached 41ºC before and no reboots have happened.
Somebody knows what range of temperature should this phone work with? I mean, not to provoke a reboot nor to damage the hardware.
I usually use and HTC one that is 1A at 5v and my neo is perfect... for example Samsung give you also a 1A at 5v Charger
That's what I wonder.
If all phone batteries are similar in the technology they use, why Sony provided a cable that reduces the charging current?

I don't know if it's a kernel/rom problem, or a hardware controller that's at fault, but ever since I got this phone charging in car chargers, computer usb outlets, and even alternate wall chargers has been painstakingly slow!
It takes forever to charge, and takes a dedicated powerful wall outlet to even do anything.
Anyone else experiencing this?
The default Samsung Provided Wall outlet charger provides .7A of power, while USB provides .5A of power max. Also what percentage do you charge it at, and can you take a screenshot of your battery usage graph?
The 3rd party chargers that designed for iDevices are not recognized as AC chargers and will be charging at USB mode which is much shower.

According to Entropy512, here is the quote:
Improved battery charge algorithm for faster charging - Initial research indicates we have an alternate battery charger chip (MAX8922) that differs from the MAX8997 used in the I9100. We DO have an 8997 also - but on our device for some reason Samsung decided to use an alternate chip instead of using the 8997's built-in charging. This means we have far fewer options (90,400,660 mA) in terms of charge rates compared to the I9100 (from 200 to 950 in 50 mA steps). So we might not be able to implement any fancy charging algorithms.

So if I am understanding correctly we were limited to 660 mA at max and unless some way to change it is found, there is unfortunately no use from more powerful chargers .

Perhaps you have either a faulty battery or a faulty charger.
Here is a link where you can buy a new battery and wall charger for under 8 bucks for both with free shipping!
Check it out here: http://www.ebay.com/itm/1800m-BATTE...045605?pt=PDA_Accessories&hash=item43aa9a4465
Put your phone in to power saving mode and see if it charges faster.
Other wise exchange it under warranty.
I've experienced that this devices charges significantly slower then my previous devices.
I found it odd when I saw the stock a/c USB adapter outputs at .7mA so i did a starch and found an article out there with a statement from Samsung stating that their devices are designed to charge slow because it's healthier for the battery.
I don't know if the charging current is restricted by some code in the kernel or a physical chip in the main board.
Sent from my SAMSUNG-SGH-I777 using xda premium
It is true that slow charges do increase the overall life of the battery. Also not charging it all the way or discharging it all the way will keep the life of the battery. If you discharge the phone all the way down, it will take much longer to charge than charging it back up from 20% or so.

Can you please post the output voltage and amperage for the battery charger on that accessory? Should be either on a sticker on the bottom of the device our written in fine print on the charger.
Also just to double check, it does not charge a docked device, just the spare battery?

Physical chip. However on other GS2s and original GalaxyS phones, the chip was fairly controllable by the kernel.
Ours isn't - it has three settings. 90, 400, 660 mA.

It is 600mA, and it just charges the spare battery.
I strongly advise against buying third party batteries or chargers. The Galaxy S 2 (AT&T version) uses a battery with NFC technology. Using anything other than an OEM Samsung battery, or an NFC compliant battery could cause damage to your device.

I'm wanting to swap the .7 amp stock Samsung charger for either a Motorola 950 mAmp or a 1.0 amp charger. Is there any danger to this? I wouldn't assume so, just a faster charge.
Then again I'm no electrician so I don't know.

I use the 1amp Monster charger and it makes no difference in charging speed. From what others have posted our phones charging chip limits the input no matter what charger you use.
Oh really??? That sure is discouraging... Well thanks for the heads up
I can verify that from personal experience. My charger I leave in the living room is a stock motorola brick originally with the atrix. And I've never noticed any difference between that one and the samsung branded one that came with the phone.
Though the motorola cord is stupid short. Any motorola users out there know what I'm talking about.

If it didn't you battery would explode. You can use anything up to 2amp (I've used my playbook charger) and you should be fine, but it won't change the charge speed.
Lithium batteries have a very specific range of operation, and do not tolerate excursions outside that range.
Charging (or discharging) at too high a rate will cause the battery to fail because it increases battery temperature, and because it encourages the growth of dendritic Lithium metal which will short circuit the cathode and anode (increasing temperature). Overcharging and discharging can also cause failures, but most Li-Ion batteries have an internal chip to prevent these situations.
Initially a failing battery will "puff" due to gas generation from the breakdown of electrolyte, but the cells are vented to prevent them from exploding. If the failure is allowed to progress (for instance if the battery is left on charge at too high a rate), the battery will ultimately achieve a condition of "a highly energetic exothermic chemical reaction". Temperatures well above 300ºC are possible - and you can't put it out since it's not combustion, it's a chemical reaction.
It's hot, and it generates a lot of smoke, and it'll set things nearby on fire, but it doesn't actually "explode".
Dang I feel dumb when I read posts by people who are obviously way smarter than me. I mean, I know it's not a high bar, but still.

I agree with t most everything. watch a video off a li-ion battery exploding (out lighting on fire) they are very violent. The only gripe I have about that last post is burning and fire is still a chemical reaction... I would compare it to thermite which is a rapid oxidation of two metals (which I'm not sure if that classifies as burning or not? HMM) =P just poking fun
PS. Thermite can "burn" without the presence off oxygen and so it doesn't burn... Just reacts. I'm assuming that li-ion does the same...

Basically, anything with a rating of 0.7 amps or above which shorts D+ and D- together (indicating a dumb charger) will behave the same.
Our internal charging chip limits to 650 mA on AC and 400 on USB. So the only thing you have to watch out for with cheap chargers are:
1) Voltage WAY off from 5 volts (USB standard) at 650 mA load
2) Does not properly signal "dumb charger" causing the phone to charge at 400 mA
So I got a 1.0 mAh USB charger from a Palm device and so far it seems to charge significantly faster.
Not trying to argue the science behind it but that's what i'm seeing.

What's the charging time difference?

I don't have a specific time. I can try clocking one once it discharges but it was MUCH faster than stock. Like I'd wait several hours for about 50% and this one does 40-50% charge in about 1 hour if not less

Might have issues with your other chargers then. That's about what mine charges at.

This is with use which always slows it down with my charger.
But i'm not denying it may be my charger. Anything is possible.
I also noticed the palm cable is a lot thicker. Idk if that's significant in this application though.

Could be. In general rule of thumb is the thicker the cord the better. Though usually stock usb cables are great. You could try a different cable with the brick.

Wondering if anyone has tried it? I remember reading that the wall charger from my Tab 10.1 was more powerful than for the phones because it would take FOREVER to charge. Wonder if it's compatible with our S3?
Anyone?
I believe that anything that charges on USB is just getting 5 vt, so any charger would work with any phone/tab if it is charging through USB. I would guess that the wall chargers are also putting out 5vt and would therefor be fine with any mini USB plug charging device.
Easy to check, plug it in and see how it works. (Buy insurance first )
Yes,
I have been using my tab 10.1 charger since the first day I got my sgs3.
It DOES charge faster, about an hour for a full charge from <8%
No problems I have noticed, and I am using blazer rom.

An hour, eh? Nice. I thought it would charge faster but not that fast.
And im definitely talking about the using an outlet, not usb.
Thanks for the confirmation!
No problem,
I knew you meant the AC charger, and that's why I posted. USB charging is slow until someone adds in the fastcharge ability to a kernel for our s3's
Glad I could be of help.

Any modern device will limit its own current draw to what is needed to do the job. While it is certainly possible for a charger to be underpowered resulting in slower charging it should not be possible for a charger to be overpowered. That is, there is some maximum charge speed the phone is capable of and that limit is expressed as its maximum mA draw. a charger that sources under the max mA will be slower than one that meets or exceeds it. A charger that exceeds the max mA will not charge any faster than any other charger that also exceeds the device's max mA regardless of the differences in their source capacity.
So, if that makes sense to you then you should know it ought to be safe to use a powerful charger and that if faster charging results then the stock charger is in fact underpowered for the device it was paired with.
Disclaimer: Any engineer worth his salt is going to current limit the charging circuit on the phone. However, if this were not the case then providing increased charging capacity will most certainly damage the device.

Basically youre saying the phone itself wont pull in anymore draw than it knows it can handle. So I guess if it does charge faster than great. Long as it dont fry im happy!
can anyone give recommendations for the xperia z tablet? on a side note, anyone happen to know the maximum amps that it will safely accept? i've seen some iphone chargers that claim 2.4A, but not sure if that would be compatible with an android tablet or if there is some kind of regulator in the sony tablet that would prevent it from accepting more than what the default charger outputs. i'm also wondering about long term effects of using something that has a higher output compared to the stock charger. would that be a reason for concern?
The Xperia Tablet Z has an internal limit of 1.8A. That's 300 mAh more compared to the one that comes with the device (1.5A). You can buy an iPad charger (2.1A). It won't cause any problems, because the device won't recieve the other 300 mAh. If I'm right, those are dissipated with heat on the charger itself.
thanks! thats just the info i was looking for.

It's not really recommended to change chargers on your tablet.. i even spoke to Belkin care yesterday i asked if this charger will work with my Tablet Z clicky Belkin said to me even tough it will work, with my Tablet Z. But they do NOT recommend it, as long run it will destroy the battery life... if you really need juice on the move, just pick up a charge pack that Sony sells on there website...
No idea how it affects battery life but the ipad 4 charger will charge the tablet Z in like half the time.
I have tested this myself.
I went back to the orginal charger because i charge overnight anyways and i don't want to kill my battery.

i own ipad charger 2,4A and it helps to charge the tablet only 30% faster, not half time. Original charger doesn't manage to charge the battery from 0% to 100% for 6 hours, so it's no good( The ipad one makes it in 4.15.
I have noticed that it takes much less time to charge the tablet with the latest 4.3 update.
I ended up getting this one http://www.amazon.com/gp/product/B004OZMWUS/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
it had a lot of positive reviews, a 6ft. chord and charges at 1.8A, I figured anything over that would be overkill.
I know there is a thread about what charger to buy, but I have a specs question. Mine z5 came with the International charger and I am in the US. I noted it is 5v and 1.5a. I have a 5v 1a charger on hand. Can I use that?
Sure, it will just take longer to charge.
No lasting negative effects on the battery?

Most certainly no negative effects. In theory it should actually be better for the battery to charge it with less current, but I don't know if that is true.
Different topic: I read that there are multiple versions of the Z5 (US, Europe, ...) and that they support different LTE frequencies. So maybe you want to check if your mobile connection works as intended, if you don't have the US version.
My phone is showing LTE after choosing my apn settings.
I tried using a 5V 1A charger with my phone and it doesnt seem to work. (It works fine on my old phone) The charge light keeps turning on and off. The vibration pulse you hear when it starts charging keeps pulsing too.
Better use an HIGHER amperage, than lower!! Charger will adapte it to phone specifics...A lower amperage will reduce your battery capacity in long time.
I once connected my Z5C to an old 500mA charger (caught the wrong cable) and kept using it a bit (screen on, etc.) and it gave me a nag screen that said that the charger is not suitable because apparently the battery drain from usage was more than what trickled back in.
However, if left alone even a 500mA charger should eventually charge the phone, taking much longer though.
Generally, with chargers, you need to get the voltage right. If the Amperage is higher that what the OEM charger is it does not matter. The electronics in the device limit the charge to what the device can handle. The Amperage on the charger is the max it can deliver. In other words, the charger does not pump 2.5A into the phone forcefully, the phone just nibbles whatever it can take (say 1,5A).

Any reliable source for that? The charging will be slower - yes, but I seriously doubt, that this has negative long-term effects on the capacity.

I think you need a 2A charger to be sure with the Z5c. Most of my older chargers take hours to charge it, and the car USB port (Nissan Qashqai 2015) barely charges it at all.
The UCH20 that came with the phone, takes 2 hours 15 mins to charge the phone fully. I got a quick charger which takes around 1 hour and 10 mins at max
Wow, really?
It is basic electronics. The voltage must be the exact one. Amperage is what the device draws , therefore the charger must be capable to provide a minimum not a maximum.
I repeat, it is basic electronics!
Now a more pertinent question :
What are the voltages for quick charge ? Does anyone know?
If someone has a original charger with quick charge can you please state what voltages are written on it?
Should be 2 or 3 voltages with lowest 5V
Edit : Found myself the info on Sony UK website of a Sony charger.
