[Q] Charging the battery ??

We all know that charging with the stock charger is very very slow so i was wondering if i can use a charger that outputs A) 5.2V/2.4A B) 5.1V/2.1A C) 5.0V/1.2A these are all charger that i have which one is the best to use without damaging the battery ????

none, as long as the charger your using isnt weaker than the stock charger, it'll make no difference. Having a 2amp charger might produce more current, but the phones going to accept only what its programmed for, which is what the stock charger outputs.
Its safest to use the stock charger with the stock cable, and if your phones fairly new, don't worry, charging speeds up after a week or two.

Phone has power supply control chip that limits the maximum charging current (1A in case of HTC One). Unlike fast USB charging maximum charging current is not something that is possible to be changed from any software.

Question about charger

Hello I have two questions... First is if I can charge all the phones with the fast 1500mah charger of Xperia Z1???
To my old Xperia sp, charger was 850 mah, can I charge an Xperia SP with 1500mah charger?

Yes your phone.will only take as much.current as it needs

so i can charge with the 1500 mah charger a battery that is 1650mah capacity ? but it wil charge FASTER than a normal charger ? that's the point ?

Wait, you are mixing things up! Your Xperia Z1 Charger does supply 1500 mA (which means 1,5 Ampere) of current at 5,0V DC.
Your Xperia S Battery has a Capacity of 1650 mAh (or 1,65 Ampere Hours) which means that it can supply 1,65 Ampere of continuous current for 1 hour (at 5V, I guess)
So: Yes, you can use a bigger charger and it will charge your phone faster, in this case nearly twice as fast. This will not damage your phone, as it will (as already said) just take the maximum current it can make use of.

I thought it was the chipset/kernel which had fast charge capabilities, not the charger?
If the phone only takes the maximum current it will make use of, it doesn't matter what the charger is spitting out, the phone will only draw what it needs to.
I could be wrong, but my Nexus 4 charged at exactly the same speed when I used my Nexus 7 charger as it did with the stock charger.

You are perfectly right! And it's also what I wanted to say. Of course if your phone is not able to draw more than 750 mA, a bigger Charger is useless.
But one can safely try it out!

Charging time?

Is it just my device or does this thing charge super slow? I can't even get a full charge in a hour and a half and the battery is only 410mah.

Do you use original AC Adapter? I use another one now and I can get it charged in 45 minutes, which is ok to me.

bad battery
I have been having really bad battery on this yesterday left it a home with a full charge at 9.0am and today at 7.30am had 11% it had screen always off and it had not been touched thinking of send it a off to LG to be looked at

I'm using the turbo charger from Motorola. I guess I can try another brick.

I use my Samsung charger with 2.0A and from 5% to 100 in an hour.. My orginal LG charger was only 0.7A!

I would advise against doing this. You will shorten the battery life due to the extra heat produced. Always use a lower amp charger unless you are in a rush!

Can someone tell me how long the actual charging time exactly takes ?
I use the original charger that comes with the device and it takes about 3 to 4 hours to fully charge the watch.
I find that quite long as I read the comments here.
The first tames it takes only 1,5 hours to charge it but all the other times it goes real slow.
A factory reset didn't help to resolve this issue.
Thanks.

As far as i remember battery have a capacity 410mAh, original charger have power output 700mAh, so charging time should be about 40-45 minutes max.
Change usb cable, if it doesn't help change charger (but it should have power output >700mAh)
PS. AFAIK using charger with power output >700mAh is harmless because watch limits charging current by itself.
Measuring charging time is best indicator.

Charging with 2.0A adapter will not increase the charging speed - the watchregulates the charging current, it will not just blindy "connect" the charger to the battery (in fact, I can't think of any piece of electronics that would have the charging logic in the adapter nowadays).
I had no problems with any chargers, not even with USB charging - the battery is very small, so unless you have a charger that can't put even 500mA you should have no problem.
I've seen an issue where the watch was "charging" constantly and ended with 85% and wouldn't charge anymore - reboot fixed that and it showed 100%.

I was thinking that your charge takes so long because you could have some process draining your battery in the meanwhile (that starts when you connect your phone, like a tasker thing or smt). Newbie thoughts so correct me if this is impossible

I could try to do a factory reset and see after that if it charges much faster then now.
For the moment i have a few apps on the watch, i do not know if it matters or not for to influence the charging time.
It's weird that we do not have the ability to load the watch while it is off.
From the moment that i put it on the charger it turns on automatically !

hello my friends.
the charging dock is limited to 0.85 A (850mA)
It makes not more sense to use a Adapter with 2.0 A Output. It won't charge faster.
Look if every pin on your dock is ok.
also the connection pin on your watch.
Try to clean a little bit with high percentage alcohol.
best regards

Problem solved by using another USB cable.
Now fully charged in 1,5 till 2 hours.

I haven't measured the charging time of my watch but it looks to me pretty fast. I guess with original charger 30 mins - 45 max, not a min more.

Don't sweat the amps

Hi,
that statement isn't particularly correct. The charging system in the watch (as with any LiIon battery) will draw as much current as is "good for it" and no more.
Just because a charger offers 2A doesn't mean that this is the amount of current flowing through the charger / battery!

[Q] Quick Charge 2.0

So yesterday I bought a 2.0 charger off of amazon with the choe brand name. According to the ad it works with nearly every android phone, including the HTC one m8. For the past year I have been using a charger from my last phone which was a crappy flip phone and thought nothing of it, but I am wondering does this charger truly work?? According to app "Ampere" it is much slower. Also, I've read reports about phones heating up and that's what mine did last night, is that normal? How long should it take for me to full charge my HTC one m8?

It will heat up, that is normal. It'll use most of its 2.4A between 20 and 70% and then slow down. Your total charge time shouldn't take more than 1 hour, and make sure you're using the supplied cable.

Thanks for the response! So if it doesn't charge 1 to 100 in 1 hour than is something wrong? Also will a charger like this have any effect on how long my battery lasts? My last charger for whatever reason was for my last flip phone believe it or not, I never bought a new one.

no I wouldn't say that.
my 2.0 QC will get it done in about 1-2 hours compared to the 3-5 or so it took with stock charger.

0-100% will take more than an hour. I've timed mine a few times from 0-100%, not using the phone at all and in airplane mode waking it up every 5 minutes to check percentage, volts, and charge rate using Gsam batt monitor.
Comparing the two chargers (OEM HTC QC 2.0, and original HTC charger- which I believe is QC 1.0) the QC 2.0 is definitely faster. Even though there is nothing on the phone telling you it is using the higher wattage charging mode, it is. So, 0 to 100% using HTC's QC2, usually takes around 1:20 minutes if I remember right. As in the other post, it starts out rather slow to around 20%, then kicks in to high gear until around 80%, then slows back down all the way to 100% so as to not overcharge the battery and harm it. It really is amazing the speed that it charges at. It does get rather warm, which is normal, but shouldn't hurt the phone.
Now, completely draining and recharging these batteries frequently is not good for them and will decrease the useful life sooner. Keeping it somewhere around 80 % is ideal but realistically not practical and the manufacturers know that. That's why they build in overcharge circuitry protection so leaving the charger on all the time "shouldn't" harm the battery. Draining it down to zero and doing a full recharge cycle on it frequently WILL decrease the lifespan. The batterie's useful life is basically determined by a finite number of charge cycles.
There's tons of info on charging and batteries out there if you are looking for more reading too.

Anyone heard of the brand Auzen? It's popping up alot on aliexpress and around asian market. Not too much reviews yet on that brand.

don't play with quick chargers .I bloated my m8 batt once trying it .it charge at 2.4a .our device max is 1.5a.
If you insist using it then don't full charge with it n monitor closely .

That's impressive, I use a QC2.0 car charger, I use a variety of wall chargers that run from 1.0A to 2.3A at 5V.
So far, my battery is still very happy.
Sounds like you got a cheap knock off charger or your battery/charging circuitry was damaged/faulty and/or your ROM/firmware weren't proper, for that kind of damage to occur.

I don't think Ampere works. I once did a test (last month) and had 6 different USB cables and I wanted to see which was the best, every time I used one I got a different reading, from 200 up to 1600. Even using my Anker Quick Charge 2.0 I only got 400 so it stated.

I have been using Aukey QuickCharge 2.0 and gives pretty decent charge times.

I have a QUICK Changer 2.0. works great.. have some tips...
You know there is some colors on cable conectors ends you have to choose the right one..
- If the cable is not a quality one can result to slow charging.
Black ----- 1.0. most in stock phones
White------ 2.0. the right for fast charging...
The time on reaching 100% on battery,well Quickly charger 2.0 will reach 80% on your battery fast and it will change the next 20% slower...
There is some app in playstore can help can see the amperage live in mA..
Connect your charger to get the battery charging current or disconnect it and get the negative discharging current... and you can see your battery charging current mA is constantly changing because even on charging phone still using current (negative discharging current) and this is always changing.
On my case I see higher mA reading only under really low battery...

I have a problem with my m8 and aukey 2.0 quick charger....
After firmware update to 6.12.xxx.xxx mm , the app ampere tell me max 1600ma before update its tell 2000ma .. Its a bug or a feature of the new firmware base...??? I have cyanogenmod 13

Im using the same aukey 2.0 quick charger. Works perfect.

M8 is 1.5a max .if you use 2.0a logically you're overcharging it. Just wait for it to get bloat n replace the whole bat. worth it ?

Hi, i just wanted to say something. After many bad chargers i bought, i found the Nillkin chargers (2Amps)and Nillkin cables (2.1Amp) the best and best quality. I am always testing with good Usb voltage tester and it can charge up to 1.5 amps max on M8 and on LG G3 1.8 Amps. As long as the charger is 5.0V, amps can variate and it doesnt hurt your battery, it just charges slower or faster. In my case its charging 1% per minute on both phones. It doesn't matter if the cable is black, white, green... cables must be thick, around 18AWG that support high ampers which mean faster charging. thin cables are sh!#. And for car i also found the Scosche dual charger great for every device with Nillkin 30cm cables and Kenu airframe holder.
You can use 2.4A chargers on M8 without problem as it will only receive 1.5amps.

I'm using Anker PowerPort 1+. It's very good and you can use for iPhone iPad & almost Android devices.
I bought it here: http://www.amazon.com/Anker-Charger-PowerPort-Samsung-Wireless/dp/B014F3D8FQ

That logic is incorrect. The phone will only draw as many amps as its rated for (1.5 amps) regardless of what the charger is rated to supply. Think of the charger amp rating as the "maximum it can supply" instead of "what it will always supply".

Ampere shows max charge rate for me at 2000ma. Where do you get the idea it will overcharge?

Z3C charger specs

Can anyone tell me what kind of charger does the Z3C use? I think I lost the one that came with it.

Any charger that has Qualcomm QuickCharge 2 built in.
They are a little bit more expensive, but are worth it in my eyes.
They charge a lot quicker than normal chargers as the charger monitors battery temp and delivers maximum charge without stressing the battery.
I can charge my phone from under 10% to charged in 2 hours and it's not even warm.
When I plug the phone into my PC at work it gets really hot and I'm sure that's not good for the battery.

It CAN be charged by any QC 2.0 charger but you won't get any out-of-the-box. The standard charger is EP880 paired together with EC803 charging/data cable. My original charger stopped working after just 10 months and now I'm using Blitzwolf BW-S2QC charger.
But it's true - quickcharging a phone does not even make it hot or anything like that. Unless you start using it but it's my case
I recommend buying QC 2.0 charger.

Be sure the cable you are using supports quick charge 2.0 as well
