Charger rating - Samsung Galaxy Ace Plus S7500

I lost the charger that came with the phone so got myself another charger. This new charger takes a hell of a long time to charge the phone, takes around 3-4 hours to get a full charge. I see that the Current rating is a pathetic 0.7A.
Could anyone let me know what is the Ampere rating of the charger that came with the phone? I'm thinking of buying a 2A charger for quick charging, anyone using such a charger and will that be safe? Thanks in advance for the answers!

It's 0.7A too.

Battery charging, 500mah (slow) or 1000mah (fast) any difference in performance?

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.

[Q] Buy a new charger or not?

Got my new moto g yesterday and its damn good but the thing that frustrates me is the charging, I got a charger with 550mA output and it takes about 4 hours to charge from scratch. I am thinking to buy a new charger and read somewhere that the max cap is of a 1.5A power supply, I need to know how much power supply should I have for maximum battery years. Should it be 1.5A or my current charger or something in between like 1200mA. Thanks in advance.
It really depends on the electronics circuit inside the moto g and also on the one in the battery.Motorola says max recommended is 1,5Ah.I`m using an HTC charger (the old ones) with 1Ah / 5V rating , its charging it for about 2hrs.Also tried with Sony 880 charger (1,5Ah, and it took ~1hr and 30 min.But what I can tell you is that if the charger is high quality one, they all follow the 2( 3 ) step charging in a nice parabola.
If I were you , I would have gotten something with higher amps, like at least 0,9-1,2 at least, cos waiting 4hrs for it to charge is a pain, otherwise it wont be a problem for the batter at all.

A slow charge is likely to be best for overall battery longevity so as a balance I'd go for something around the 1amp mark. I use a .75a Blackberry Charger - takes 3hrs to fully charge from empty.

[Completed] Charger help pls

Just bought a new nexus 4 and I've noticed it takes an age to charge anyway I found another two chargers at home and on one of them it says fast charger and the cable is a lot thicker and the other is just another charger but its made by motor rolor.Now when I plug the fast charger in it says its going to take 30mins less than the original charger to complete and when I plug the motor rolor in it about 15 mins quicker than the original charger .my question is would i be doing any harm to my battery if I use the other chargers and should I just keep using the original one.

Nope
You Can Use Any Charger
Cheers
Hi I've been using the fast charge motor rolor charger and its actually taking 2 hrs quicker to charge my phone .now I haven't had a phone for a while my last device was a galaxy s2 and I'm sure it never took over 3hrs to fully charge.so I'm thinking maybe the nexus original charger was charging far to slow anyway.any thoughts on this? Thanks again

Fast Charging?!?

Hello.
Can someone explain me how on earth does fart charging works on this device?
I've tried the included cable and charger, third party chargers and i don't see any fast charging going on?!? or any indication on screen that it's happening.
I've read somewhere that you need a special cable to use with the included charger (?!?!) is this true? where do you get this cable?
Phone is amazing but the charging part is really is really weird if you ask me.
Thanks.

do you get any message saying fast charging?
it doesnt show any fast charging message, so i wouldnt rely on such a message to make sure its working. just use the included cable and charger and ull be fine it takes about 2.5 hours to charge from 0-100% via fastcharge

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol
Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00
trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.
I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.
Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.
i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...
Sent from my Huawei Mate 8 NXT-AL10 using Tapatalk
Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.

Charging thoughts.

I just got this wonderful phone, but there are some mysteries that I would like to get solved. Mostly, they are about charging. I would like to use wireless charging, but most QI chargers only deliver 600-1000 MAh. If it delivers 1000 MAh and the power conversion rate is set by manufacturer to 70%, does that mean that it only charges with 700 MAh?? That way it will take 4.5 hours for it to charge from 0-100%. BUT... my original wall charger shows appx 700 MAh when I check it with the pro version of the app Galaxy Charging Current and the pro version of Ampere. The phone says the phone is done charging in appx 1.5 hours. What decides the rate of charging?? I have tried a LOT of chargers, even the now leftover charger from my Galaxy S4, but they don't charge as fast. Some of my USB wall chargers take over 3 hours to get the job done, and I would like a spare that does it as good as the original. There are som 3 Ampere chargeres on ebay, are any of them any good? Hope to get this clarifyed.

Hi,
Which phone? Kindly provide us the more details.
My phone
What? You are not psychic?? ;=) My bad, I thought I posted this in the Galaxy S7 forum, but must have been sleepy. Like I wrote, it is a Samsung Galaxy S7. Sorry for the slip.
