Just wondering, I found these:
http://www.amazon.com/exec/obidos/t...t_shr?_encoding=UTF8&m=ATVPDKIKX0DER&v=glance
They are the correct micro USB charging units, but they are designed for Blackberry smartphones...Will these properly and safely charge our HD2's?
I love the folding plug design.
Hello Free Man:
FWIW..I had purchased one of these exact items from amazon. Haven't used it yet but I read the backpanel and the output is 5v @ 700ma. If you look at the backpanel specs for the wall charger shipped with your unit from HTC it'll show 5v @ 1A on the output. So the unit will work but will take slightly longer, I think.
Take Care
Well as long as it is safe to use, mine should be here in a few days. I would think it would simply take 30% longer to do a full charge and I am only really using the unit to charge overnight when on the road in hotels, so that is really not an issue as a full charge only takes a short time.
Anyone else want to step in and comment on the lower rating?
You are correct, this charger will take longer to fully charge the battery.
Just like charging from a PC USB port takes even longer since that only provides 500mA maximum.
It is absolutely safe to use chargers with lower ampere rating, the downside is that you will either get longer charge time it your device won't charge at all. But nothing will burn or explode.
So you are saying my device will charge safely, just take 30% longer? You mentioned something about it not charging at all, why would it not charge?
Will this shorten the batter life or anything to that affect? Thanks!

It may not charge at all if the device you are charging needs a certain amount of amperage in order to charge the battery.
No, this will not affect the battery life or anything to that affect.
Thanks, I plugged it in and charged it for 3 minutes and it did begin charging from 69 to 80% in that period, so it works fine and is quite fast. This battery charges fast in my experience.
Hello all, first I want to say that Xperia SP is my first smartphone so there are many things that still a question for me. I want to ask, is it overcharging the Xperia SP can cause damage to the battery? Because some people said it could damage the batteries and some people said no it doesn’t damage the battery. So which one is true?

You can't overcharge a phone, heck! I even put my phone on the charger ALL NIGHT, at least 10 hours (LOL) its connected. The USB charger turns on and off as necessary. Also, you dont need to charge the phone for over 8 or 12 hours, that was for prehistoric batteries of the 90s
What damages batteries is letting them discharge a lot like 5 or 10 percent.
Do a research about Li-Ion batteries, or any other Lithium battery and you'll find how to take a little care for those batteries. Basicalle: Never let the batteries fully discharge and do not overheat them. If you live in a very hot city like Mexicali, Phoenix, Las Vegas or any other place that gets temperatures up to 45 or more degrees celcius, avoid using the phone outdoors. (120°F)

Nowadays all smartphones have a smal charging circuit board that uses simple operational amplifier logic to cut power going to the battery when its level is more that 100%.Thus stopping battery from being damaged by overcharging.
But when you leave it on the socket and it is full when the battery drops at 99% it will start charging so remember that as an extra piece of information.

So, does this is the same when we connect the smartphone to the computer? Because if we connect the smartphone to the computer, the smartphone will also recharge. Will it stop the charging when it 100% too?

Yeah the safety board is inside the phone so wherever you connect it when it reaches 100% it will stop charging.(even when you plug it in your PC)
As for Xperia SP personally i cant charge it from my PC.When i use it with wifi on the battery barely manages to stay at the same level and it often discharges when charging!!!
Even with software verification the phone draws 500 ma maximum load (the phone charger provides 850 which is significantly more).If the phone needs more than that it will recharge and when it needs less it will charge (but in slow rate)
So bottom line dont charge it with you PC if you need a fast charge! (and dont worry about overcharging)

So overcharging it will not destroy it? I often overcharge my Sony Xperia SP because I'm oversleep. At first it doesn't make any diffrence but last night I overcharged it again and the diffrence is so drastic. You said if the battery is 100% it will automatically stop charging, does it mean the power (charging) is off? So if the case like that where the electric gonna be transfer by the charger? Because I see it still charge like normal and overcharger not gonna destroy the charger? I want to replace my battery but I have to know for sure about this first
The charger is not in danger at all.The only thing the charger does is constantly providing the phone with 5 v. When the phone's battery drops to 99 % its draws current from the charger.
Also leaving the phone overnight to charge is not going to totally destroy your battery!Because its needs quite few minutes to drop while not in use so the 99 to 100 % cycle is not going to be repeated above 5 times! So bottom line ... its not harmful to charge your phone overnight. But if you have 100 % battery and leave it in the charger the battery performance will drop through the years and i bet it will not be noticeable at all!
Hi everyone, I'm looking for more info about the fast charge function of the Note 4: I can read on the charger that it either provides 5 on 9V. Does this mean that I can supply 9V on the USB port to fast charge my note 4 ? Does anyone know how the charger detects wheher it it should supply 5 or 9V?

Yes, it means that that charger will deliver power at 9 V (at 1.67 A) to the phone.
As for how it decides which voltage/current to use, it'll be as a function of the battery's charge level, temperature, and probably some other factors, but that's getting into some very specific settings for the phone/charger system by that point.

thanks for the quick reply! I've got a couple of Dc Converters (buck) and lipo batteries (11.1V) and was wondering how the phone signals the charger it can accept 9V and if I can use my DC step down to feed the phone with9V...
I guess I will have to try

I guess it requires original charger for that function, probably with kernel modification you can disable that only 9v OEM charger use for QC
Hello guys ! Do you think this fast charging function is alright for the battery ? as far as i know high current may damage the battery .

I agree that it might be damaging to the battery (but obviously not extremely damaging). Why else would there be the option to switch off fast charging? I've switched mine off anyway because I have no use for it as my phone charges overnight and makes no difference how quickly it gets to 100%.

I personally thought the option to disable Fast Charging was Samsungs' way of reminding us, or letting the uninformed know, that it can do it.
The generally accepted rule amongst radio control hobbyists is that provided the battery is well made, it's not the current that'll kill a battery - it's overcharging it (over 4.2V per cell on a LiPo). Provided that the charging circuit is good (and I have no doubt it is of a high quality) we shouldn't see any degradation in battery life when used with the fast charge process.
Others may chime in with more info, but that's how I understand it.

l believe the fast charge is safe for the battery as it charges it at 1C (=1hr charge) which is actually not so fast.
Here is my tip: I have an old charger to charge overnight and use the mote 4 charger only for fast charging during the day (I leave it in my bag). I'm actually lookingfor a way to make a fast charging battery bank.
So here is my question again: has anyone tried supplying 9V to the phone ?
best device in charging
its charging up the whole battery in about an hour, i really like that and the battery gives me a full day
So far right now i can talk for about an hour and play games for about an hour and leave it on overnight and all day and still have 82% left. I'm super impressed!

YOAH!!! Thats insane!
I know that the amperage on the charger is huge in its speed.
I used many custom Roms and kernels in the past on other phones with fast charge. I used several chargers and always charged much quicker with higher amperage outputs. Some were as low as 300 MA to as high as 1.2A. This is why the amperage is so high on this phones charger. The voltage is needed to push the charge quicker. Good luck finding high A charger at 9v.
My 1.2A charger i use as backup is much faster then the 500/700ma ones I have but they are all 5v and can't compete with fast charge.
Sent from my *ROOTED* Note 4 SM-N910W8
I'm also looking for a power bank that would be able to charge at
- 5V 2A,
- 5.5V (Galaxy Tab S)
- 9V (Note 4).
- with 2x18650
- able to charge itself fast too;
- charge-through (charging a device while changing itself).
i now have this ENB model, but it does not deliver 2A to Tab S (and charges at 5V not 5.5).
And it charges itself with 1A even from 2A-capable power supply.
Hi all,
I notice something that the note 4 does not charge fast after I installed S-View cover (original one), although an indication appeared that it is using the fast charging function.
I guessed it assume that the cover is open and charge slower. However, if I removed the S-View it charge noticeably faster.
Do you think this a bug in firmware ??
Thank you,
The so-called USB fast chargers query the device to be charged. Devices capable of fast charging at 9V DC have additional circuitry in their USB ports that the charger can detect. If the charger doesn't detect the circuitry, it falls back to 5V DC mode, like any other USB charger. Assuming the fast charger is functioning correctly, it should not over-charge an older phone or tablet that doesn't support fast charging; it will simply take as long as the original "dumb" USB charger did.
Hey guys I just bought the Nexus 6 and been looking around here and didnt find anything on best ways of charging the phone. I know the phone comes with the quick charger, but I tried it and the phone got real hot and I am pretty sure its not good for the battery in the long run.
That being said I do not want my battery to start losing charges since it does not have a replaceable battery. I am just curious if anyone on here uses other methods of charging the phone or better yet if anything is proven to be safer to charge. Right now I am charging the phone with my previous Samsung s4 charger and seems to charge fine, but if its not good to do this I would like to know sooner than later.
The n6 is meant to charge fast and isn't the first phone to use fast charge technology so I think we are fine using the stock charger.There's no way a battery charging that fast isn't going to get hot.
Define "real hot."
It is normal for the phone to get quite warm when charging. It should never be hot to the touch though. In this context, by hot, I mean you're unable to hold the phone. If you're able to touch the back, and keep your fingers there for more than a few seconds, then the phone is warm, not hot. Anyone who has had a battery overheat can tell you that the difference is unmistakable.
Chargers will, by definition, heat the battery to some extent -- how much, depends on what kind of charger. The order (from warmest to coolest) is: QuickCharge 2.0 (Turbo Charger), qi wireless charging, QuickCharge 1.0 ("Traditional" 2A charger), Regular 1A charger, USB charger (500ma). However, the heat produced by ANY of these chargers is normal, and the battery was designed to handle it. The life may be lessened by the heat to a very small extent, but it should still last way longer than the 1 to 2 years you'll likely own your phone. Plus, technically, the battery IS replaceable. It's just not designed to be user-replaceable, but there are businesses that will replace them. Or... you can purchase an after-market warranty, most of which cover batteries.

I meant just warmer than normal use of the phone. I understand the phone gets hotter the faster you are charging, however I charge my phone every night so what is the point of the quick charging except when I am at work and my phones about to die?
I just feel that the phone will last longer by not quick charging it, but I could be wrong. What I really want to know is if anyone knows if its better for the phone if you just charge with the 1.0 and if so which charger should I use? Maybe another motorola one or would the samsung one work fine?

Technically, yes, it'd be better for your battery, but realistically, you'll never notice, since you'll probably get a new phone long before battery life becomes an issue.
However, to answer your question, any 1A charger designed for Android devices will work (If they're not designed for Android, they'll show "Charging (USB)" in the battery monitor, and will only charge at 500mA). The brand isn't really important, as long as it's a reputable brand. (...and before you ask, yes a 2A charger will work fine too, but will heat your battery more than a 1A charger.)

Ok thanks...I guess ill continue to use my samsung 1a charger since it works. And I know that I wont have this phone for the whole 2 years, but if I charge the phone every night anyway why take the risk of damaging the battery at all with a stronger charger when I dont need it right?
Anyway thanks for the advice and ill keep using my samsung charger.

Hi,
Does it damage battery life or the phone itself to charge with a powerbank which doesn't support Huawei FCP? I mean If I charge my phone with ie Xiaomi QC3.0 Powerbank, is that OK?
Second question, what is the best practise to charge the battery. I mean, is it OK to keep it plugged in after 100%? What are the other points to consider?
Best Regards.
No, in fact, I have a very cheap charger on my phone, slowly charging it.. the reason is because slow chargers lengthen battery life. If I'm in a hurry, I'll use Huawei's own charger.
Batteries and their regulators are far more intelligent than they used to be. They will regulate the current at peak load.
