I've noticed that charging with 500mah charger, charges the battery MUCH slower than a 1000mah (1amp) charger, which charges really fast. I'll need to time it, but I'm thinking the 1000mah charger charges the stock battery in less than 2 hours, where as the 500mah charger takes many hours, I usually let it charge overnight.
My question is, is there any performance gain to slow charging vs fast charging? ie: slow charging giving a deeper charge, vs fast charging?
any opinions?
i use a 2amp charger i had already that fully charges the O3D in around half an hour/45 mins. get the same runtime whether i use that or the stock charger.

Any chance of a link to this charger, I'd really like that sort of charging speed.

My guess would be anything that would charge an iPad... those require like 2.1amp, so that would be a 2amp usb charger.... I've seen 2.1amp home chargers, car chargers, etc... all because of the ipad I'm guessing.
Its not that simple. Any device that uses USB for charging can only pull 500ma, that's a universal agreement. To get around this each manufacturer uses a method of "informing" their device that it is connected to a charger that can supply more current (HTC shorts the data leads in the supplied charger I don't know what LG does). I have a 1amp car charger but it still only gives 500ma but the genuine LG charger gives an amp because the phone "knows" it can supply more.
I'm going to stick a test meter into my LG chargers over the holidays to see how the data leads are connected.

The charger i have is a noname brand. I bought it from walmart for 6 quid. It also came with a 2amp car charger and a micro usb cable.
Micro usb cables are not standardised like that. Ive never heard of such a thing at all. As far as i know most phones will "fast charge" if they dont detect a data connection and dump as much current as they can into the battery so you can pretty much present them with whatever current you like and the charge time will just get faster. There is probably a hardware limit to that somewhere in the charge circuit but i dont know what the limit is. 2amps is the highest power usb charger ive seen but its not exactly aomething i regularly keep an eye out for.

Slow charging is always better as this will allow the optimal number of battery cycles before the battery's capacity will start to degrade.
So if you only ever slow charge then your battery will have a longer life cycle.
Hello,
my battery charger stopped working and i need a new one. I read a few review and i'm a bit confuesd, not every chargers with the capability to deliver 1000mAh works with every device. So which one oft them works with the desire s and delivers 1000mAh and not just 500mAh?
just buy a oem wall charger ,, easily found on ebay and also cheap
does it has any difference between 1000 and 500mah chargers? now i'm using original liveview charger with 500mah on it but also have 1A iPhone charger.

Overheating
im using an old S2 charger i think, its got an output of 5V, 0.7 amps and after flashing a costom rom, jellyfirebean im getting serious overheating issues, but only while charging with the phone on.
however i cant confirm this is the chargers problem yet
just a note, its the phone that heats up not the charger

Double that. Overheating can be only caused by the phone itself, or a defected battery (means it is near death, but for serius heating, you will notice like 1hrs of battery life for the phone).
On another note for the topic. I use 3 type of chargers for my phones:
At home my ASUS tab's one (which is rated 5V 1A at the standard USB, plus the extra for the dock, but it is ASUS specific), at work an old ZTE "dumbphone" charger (which is rated 5V 0.75A, and is a high frequency switching type, so really energy-efficient) and for any other my old SE X8's one, which is 5V 650mA (which is also switching type). Also dedicated charger cables, 1 nokia, 1 SE, 1 HTC and 1 ZTE at my car.
The phone's original 5V 1A is NRFB at the box of the phone, but I have a security backup Samsung charger (rated 5V 500mA and pass-trough type, so not really efficient, but stable) which works just fine. The S is not capable (or not enabled just yet) of fast charge mode AFAIK so no really chance for 500mA or more when charging (even when GPS and 3G on, and screen on max, which is aroung 430mA when I last measued it with a service cable).
reporting back
yeah i can confirm it was the 2 year old htc battery
i am now using 2 anker 1600mah batterys and they last a LOT longer + come with an enternal charger so i always have one charged, it also charges the old htc battery too externally so i can now use 3 battieries mwahahahaa
note i did have to delete battery stats in cwm to recalibrate
Hello Guys!
I got today a new P3110 and I discacharged it to 2% and I plugged it now to load.
I have seen the charger pushes 2A @ 5V , this is pretty much for a battery of 4Ah, I know from my batteries ( AA AAA and others) that the charging current should be max. 1/3 of the capacity of battery.
So my question is: IS it better to charge it with the Samsung Galaxy S2 charger which provides only 0,[email protected],1V ?
It would last app. 6h to charge it till its full ( can be done over night, hopefully the charger wont melt)....
What do you think about that? Woul it harm to battery(li poly) to do it with small current?
cheers
If the charger seems much then tell me why Samsung made it.

You have got to be kidding me. ITS SO THE TAB CHARGES FASTER. IT WON'T KILL THE BATTERY!!!!
Its because the tab has a much bigger battery 4000mah vs 16xxmah.
It charges it faster

Of couse it charges faster, but for long therm it will kill the battery faster. Its usual, like every battery. Every fast charger is not good for battery, I just wanted to know if somebody have a expieriance...

Battery life span is a matter of charge cycles 0%-100%-0%. That is 1 cycle and surely batteries don't discharge to 0% not charge fully to 100%
-AFAIK- Even with lithium, Its the heat build up when "fast" charging that shortens any battery life - (same with fast discharging- I would never use those apps that do so) , so I agree with shOne. I have the same model & have noticed the battery does get quite hot when mains charging,( though have never thought to check charging AH).
I would imagine that the only damage you would do with using phone charger would be to the charger, by sucking out more than it can handle, not the battery ! -
-- But why not charge it via a pc usb port - this take a lot longer (so presume much lower AH) than the mains plug in charger - Most usb pc ports are nowadays - permanently live, even when pc off - same with the usb on a modern sky/virgin box. My battery does not get hot, charging this way. I dont know what the charge rate is charging this way ,because both the inbuilt notification & my battery app say "discharging" - (although actually charging)
(I agree that Samsung have provided a quick mains charger, and wouldnt be averse to selling replacement batteries earlier than would otherwise be neccessary, !! (I wouldnt use cheap replacement batteries in any I.T. stuff - I "blew up " a laptop once as a result!!)
I believe that the 2 amp charge is reasonable with the out put of most lithium batteries for this type of device. Since it is a lithium it will not be overcharging or over heating due to sensing, it would be a serious fire hazard... fyi I use a2 amp charger from Wal-Mart and I do not notice my device really heating up...

Agreed. The worst I got was a cheap replacement off a street without a packaging for a dollar. When I plugged it in for a few minutes the battery turned extremely hit and the battery expanded as if it was a puffer fish that took an electric shock

LOL.........mine was a supposed "genuine" DELL replacement battery I got on EB from HK. On the first charge (in the bedroom) heard a strange hissing then a loud "pop". Some of the underside casing was actually melted and there was battery gunge all over the internals!

A lot of things I bought from Hong Kong off Ebay actually came from mainland China pfff.....
It's those low quality defects they send you. Mass market goods in china doesn't require quality passes unlike Hong Kong where it's illegal once they get pass customs.

OK, electronics 101, chargers DO NOT PUSH power to a a battery, 2 AMPS is the chargers MAXIMUM OUTPUT, the device plugged to the charger PULLS what it wants (up to a maximum of 2A of current) so it can charge in a reasonable amount of time, you may be able to charge your tablet with a lower output charger but all it would do is take longer to charge (if the charger even had the power output greater then the static draw of the device), which is why most tablets simply CANNOT be charged by the USB 2.0 port on a computer or other small .5 A output chargers. You may very well charge while generating less heat, because of the slower charge cycle using the .7A S2 charger, but at the same time if you try to use the tablet while it's charging on the smaller charger it may very well drop in battery percentage as the smaller charger may not be enough to maintain the current requirements to charge the battery and run the device.
So in short, would charging with the smaller charger harm the battery, NO, but if it is enough to actually charge the device it will take atleast DOUBLE the amount of time to recharge as it would with the regular 2A charger.
I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

I read somewhere that if you activate airplane mode the battery is charging faster.
Anyome using a 2A charger instead of a turbo charger?
Like a samsung 2A charger
Or a 2A power bank?
Any issues?
Because 1150 mah is too slow
I was also wondering this.I tried it with my 2,4a ipad charger once and it was charging twice as fast, but i dont know if this is good for the phone. Using the normal charger again to be sure.
With normal 1.2A charger, it takes almost 3+ hours for my phone to fully charge. I used my Galaxy Note 10 charger which is 2A and it got charged in 2 hours. I read it in the forums that even with 2A charger, we cant take the advantage of turbo charging as it will need a charger of 2.4A.
I dont know how 0.4A will make a difference but still, my knowledge is limited in this case and wouldnt want to comment on it.
The charger has to be Qualcomm QC 2.0 certified (that's a specification) to take advantage of the turbo charge mode. The amps put out by the charger is kind of secondary in this situation as the charger and phone both need to be "talking on the same page" i.e. QC 2.0
At that point (charger is QC 2.0) the special circuitry kicks in and goes into turbo mode. So its a little more involved than just throwing more amps at the phone. If you google Qualcomm QC 2.0 specification then it will give you a better idea of what it is all about.

Turbo charging steps up to 9v and 12v depending on what wattage the phone can handle.
I think our phones are 15w and the Style is 20w or so.
I can't get my phone to charge faster with a 2amp charger though, only my turbo charger.
I used digitech 2.4amp charge ans works like a charm superb....
It isn't causing any issues? Like battery degradation?
Sent from my XT1562 using Tapatalk
I've been using my Moto turbo charger every night for a couple weeks now and haven't noticed any issues. The phone doesn't seem to let the battery get over 35'C when its charging, so I don't imagine it'll damage the battery.
Think I may get a car charger soon, sometimes I forget to charge at night so it'd be cool to get a full charge on the drive in.
Battery will very likely not last as long when doing fast charging always compared to "normal" charges
Any fact to back that claim?
Im using a Belkin 2.1A charger, no problems whatsoever.
So what's conclusion is it safe to use 2a charger without doing damage to battery

I'm using a 3a charger and it's fine
You can't harm a battery with a higher amperage output charger. The phone will only consume what it is able to. If the voltage was higher (excluding quick charge adapters) then yes that will do damage, but that's a strange situation as no charger should do that unless it's quick charge.
That being said, on hand I do have a feeling that quick charge can actually do long term damage if used a lot but on the other hand, it seems to limit the maximum temperature to around 38'C. Above 40'C can cause irreversible damage to the cell. I'm using a car charger now and when the phone is in use, it gets up to around 38 or 39 and it cuts back on the charging current.
Interesting article explaining Qualcomm, fast charge, turbo charge using all the same technique under different names. They all use the same Qualcomm technique.
