[Q] charger question

Hello,
I have a micro usb charger that cam with my hp touchpad. looking at the label it seems like it supplies a 2A current as opposed to the 1A our phone takes. Can i use it on the G2x resulting in faster charging or will i damage the battery?
thanks,
Ismail

You can use it as long as it supplies the correct the voltage. I use a 2amp charger with my G2X and I love how fast my phone charges. The phone will only draw as much as it can.

A faster charge results in a hotter battery. Some people think fast charging the battery is also the cause of the infamous SOD (Sleep of Death). Keep an eye (or ahnd) on your phone and make sure it is not getting too hot while on the charger.

The hotter the battery goes, the shorter the battery life span will result as li-ion battery doesn't quite like in hot temp. Never tried a 2A charger to charge my G2X, so I would not know. But I am using a 1A charger to it and it works great If 2A charges does not cause the battery to go too hot, it should be fine.

I've been using this charger since May with no issues. The battery will only draw as much as its capable of drawing. As long as the voltage is the same as the stock charger then there is no issue. You could connect it to a 5 amp charger and it would still only draw the 1.x amps its designed to draw.

Going too low on amperage is where you have to be careful.

thanks for the replies, turns out that 2A charger is 5.3V as opposed to the 4.8V LG charger...

+1 on that, LG may be dumb, but they're not dumb enough to let their phone overload with un-needed electricity.

slow charge

I read a post here and I didn't quite understand which charger should I buy for a quick charge.
Appreciate the help.

The one that came with the phone.
The phone will only take in what it needs.
This phone charges the fastest I have ever witnessed on AC obviously.

only use the charger given with the box cause they have settled some voltage parameters according to phone's battery ...so dont go for any other charger ...it might heat up your battery or any wrong can be happen to u ....
bro it is 2300 mah battery so it takes time to fill up some juice into battery ...
dont worry

Any 2 amp charger will work. 1 amp chargers will work too but won't charge as quickly.

All (good) USB chargers are going to charge at the same 5V as the Nexus 5 charger. Any charger from another phone will work without issue, but if it's under 1.2A it will charge more slowly (many are 1A). Just don't buy a cheap, poorly made charger and you'll be fine.

The major assumption here that a slower charge leads to a higher run time is not true.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
A slower charge leads to the saturation charge phase taking less time while the constant current phase takes longer. The battery in the Nexus 5 and the accompanying 1.2A charger is meant to give you the quick 70% charge that is discussed in the BU article and then trickle charge during the saturation charge. If you're charging overnight it doesn't matter which method you use, you'll still reach 100% around the same time and the runtime will be the same.

Tnx everyone, I have the original chargr but I lost is cable.
I tried many cables but that just are not fast enoug.
Any idea where I can buy one?

[Q] Galaxy S5 fast charge?

fast charge is generally a feature that needs to be built into a custom kernel

Don't know about you but my S5 chargers incredibly fast compared to my SIII and Nexus 7. Even with fast charge on.

Agree, my S5 charges at 1.2A given a charger capable of this, and that is fast.

correction S5 chargers are shipped with a 2.0A chargers and it charges at that rate.

Yes, the S5 charges at 2amp. (Kernel reports 1800mah)
If your phone is reporting that it charges any slower than that, it's an energy deficiency of the charger supply, bad cable, or bad micro usb connection.

I use an app which reports charging current. With a standard micro usb cable i never morw than 1200 mA (and about 450 mA from a PC/mac usb plug)

While it's true that the phone ships with a 2A charger, the charging current does not exceed 1.2A AFAIK.

Gotta love MicroUSB 3.0.

It already charges from under 10% to 100% in a mere 2 something hours (bundled charger and USB 3 cable). You want something much faster than that???

Yes I think in the end it is something around this current. What the apps report is more "charging in 1800mA mode" and not really charging with continous/real 1800mA. If you like to know more exactly what the current is you may write down time/percentage values for e.g. every 5% of battery power starting with an nearly empty battery. Then you can draw an line of the effective loading current.
With the original charger you should be able to get stable 1800mA but if the loading circuit of the S5 really goes this high I did not check.

I believe it peaks at 1800mah with the screen off. It is 1200 mah limited when screen is on.

Sorry to awaken this post.
As most of you, my S5 reported charging at stable 1200 mA with wall charger, probably 1800mA when turned off.
But, I can say a custom rom unleash battery charging in the same conditions as stock rom. I get stable 1800 mA with LineageOS, even screen on, with original charger and usb 2 or usb 3 cable.

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.

Honor 6x charger related.

Is it ok to use 5v and 3.4 amp approximately 17.5 watts output charger to charge my honor 6x bln-l21 model? Or it will damage my battery life. I have tested it it charge my mobile but I want to know that it would b ok to charge my mobile with it? Company recommendation is 9v 2amp output charger.

I think you should use stock charger....
Otherwise it will decrease the life of your battery..also can decrease your battery backup..

But the company said it supports fast charging upto 18 watts. And the one I talking about is 17.5 watts charger. Also the stock charger came with smart phone charges very slow 3.30 hour to be fully charged.

It may damage in long term but now a days batteries are designed in such a way that they will suck only power as per there design and architecture. Even if you use 10A charge it may damage but battery will just use the rated power it designed for. It wont accept entire 10A.
You may use 9V/2A charger..if using high rated one, it will just make little difference not charge in half time

Thank you all for your reply and your precious time...

Read this http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries when you'll have 10 minutes like to dedicate on reading these declarations on li-po batteries, to understand better good and bad points that rotates about fast charging personally i never used it, it'd be possible through a custom kernel but in my case, 40-50 minutes to obtain a 40% (that is also what i use daily, more or less...) is more than enough.
