hey guys i am having two chargers, one the stock one and another from htc hd2
when ever i charge my battery with stock charger., it takes 3 hours to get 100 pc and mA seen with my battery monitor widget is 570 mA
but if i use htc charger it charges in 1.45 hours and mA varies in 600 to 1200
should i use htc charger??
will it harm my phone or battery??
please reply fast

Probably not the best idea to bark orders like, "please reply fast", especially at this particular time in this forum.
Your mA should be somewhere in the neighborhood of 4350mA fully charged. What you've stated above doesn't make sense.
Sent from my Atari Falcon030
What you are seeing is the difference between a low amperage charger and higher amperage charge (or watts if you prefer)
The so called "rapid chargers" will push a higher milliAmp to charge devices quicker
i.e. the difference between an iPhone charger and an iPad charger iPhone = 5volts 1amp, iPad = 5volts 2+amp (technically is 2watts, but i'm not in the mood to convert to amps)
Now whether or not it may damage your phone I can not answer, however I have been using a 2watt iPad charger on my phone for quite some time with no ill effects... just charges a we bit quicker.
mA is per second ...have u ever seen battery monitor widget??
should i use htc charger or not?
I don't have to see battery monitor widget.
mA or milliamp or even milliampere is a measurement of electrical current through any given conductor (the amount of power something can push or pull at any given time)
Batteries are rated in milliamphour or mAh, which is the amount of current a battery can store and release in any given hour.
The HTC charger shouldn't cause any problems because the battery charging controller should be built into the phone and the batteries are protected to hinder overcharge or over-discharge.
However, I will not state that it cannot cause any issues because I'm not a Moto engineer, so I don't know for sure what the hardware can withstand.
But, as I said earlier, I charge my phone on an iPad charger consistantly, and have not had any ill effects as of yet, and I can almost guarantee that the iPad charger pushes more current than your HTC charger.

Which Battery Monitor Widget are you using? Made by 3c? or fsinib?
I'll check what my phone states while charging on the iPad charger.

I've got the app installed, have to wait for a full charge cycle before it will start returning proper current... I'll let you know what I find A.S.A.P.
I've been using the 2 Amp HP Touchpad charger for almost 6 months without any ill effects.
Hey i was just curious whether more electricity flowing through my phone would damage it but as you all guys said it wont as the battery has some anti overcharging system and you guys have been using other then stock chargers ...then im also using ...thanx to all
Motorola has a Travel Charger that apparently supplies 8watts which converted at a fixed 5volts is 1.6Amps or 1600mA
Motorola states that it is compatible with our phone...... I think we'll all be just fine with whatever charger you want to use!

i've been using battery monitor widget & system tuner (both free) for nearly 1.5 month
the current u r seeing "570mA" with stock charger is ur charging current +/- ur consumption current
another charging current "600-1200" is from htc charger
our stock charger has max o/p capacity of 850mA @ 5.1V .... similarly u can check htc's o/p capacity (i guess it is 1.2A @ 5V)
observe your consumption while heavy/moderate usage & standby it will vary
it is simply average current consumed in 10 min. timespan (pretty sure we can't change it)
m plannin to buy both after stable ICS release

Hello guys ;
I didn't see anything like it , so i decided to make a guide for a portable charger.
This is especially handy if you have leftover batteries from old phones , you can't use them on your new phone but they still function. Why throw them away ?
Instead you can make a portable charger with it. Even AA ones will work. (Rechargeable recommended but not necessary)
You would pay 30-40 dollars for a portable charger with 5200 Mah capacity , What I'm offering is 12 Dollars for 7000 Mah Capacity.
So , It's practical , has a low cost , easy to make , has a high efficiency and if you have a little creativity it would look great.
First you need to understand the mechanics of a lithium-ion battery (Which we use)
It consists of a lithium ion solution , an anode and a cathode floating in the solution.
Lithium ions will move from negative (Cathode) to positive (Anode) taking electrons from lithium ions in the process , thus making it neutral.
This process is reversed by charging , delivering a desired current to lithium atoms will ionize the solution and making the neutral atoms , ions once again.
The current always flows from higher voltage to lower voltage , that's why the chargers are usually rated 4.8-5.0 volts in the chargers , instead of 3.7 like the battery.
If you use 3.7 volts in the charger the current will not flow , it will balance and it will not charge.
Dump charging means charging a battery at a higher rate than the phone allows by using batteries.
P920 will not accept currents higher than 1 amp so you will not be able to dump charge your battery using the charge slot , instead you will use the wires to connect the charger to your battery in the right polarity.
you will need to hold it by hand but no worries the process takes about 30 seconds to charge it from 0% to %50...
It decreases the life expectancy of the batteries so use it just for urgent matters.
So this is all you need to know so far as mechanics are the concern.
Prerequisites ;
Two batteries (Can be ordered from ebay , 3.7 volts 3500 mah , perfect for a portable charger) (You can use only one. In that case , skip the first step)
Insulated copper wires (Can be obtained or salvaged from anywhere , quality ones will improve the current)
A Step-up regulator (Can be bought from ebay , link will be given)
A custom made case (Optional , You can use electric tape to seal it instead)
A soldering iron
Solder
1. Connect the batteries in parallel ;
Take a copper wire and solder it to one of the batteries' negative terminal and to the other battery's negative terminal.
Take another copper wire and solder it to the positive terminal of one of the batteries and to the other battery's positive terminal.
Now you've wired the batteries in parallel.
It will not increase the voltage instead it will couple the "Mah" ratings and the current.
2. Take out the Step up regulator and wire it to the batteries in parallel ;
Take a wire and solder it to the negative side of the batteries in parallel (Doesn't matter which but we will use that battery one from now on.) and to the step-up regulator's negative side (It's marked on the pcb)
Take another wire and solder it to the positive side of the battery (the battery you just soldered the negative side to) and to the positive side of the step-up regulator.
And poof , you just made a portable charger.
You can connect it to your phone using the usb female output plug on the step up regulator.
Now it's time to make a case for it or you could just use electrical tape to seal it off. (That's what i did)
What we did (In short) ;
We wired 2 batteries in parallel and made the current 3.7 volts and 7000 Mah.
Then we used a DC to DC Step-up Regulator to increase the voltage to 5 volts to promote the flow of current from the charger to the battery.
Then we built a case to put the charger in or we used electrical tape to seal it.
Notes and Advice ;
Cut the insulation on the wires short , otherwise you can short-circuit the terminals. (Or use hot glue on them)
Take a drop of solder and drop it to the battery terminal using the soldering iron it's enough to make the wire stick to the terminal.
Coat the wires with solder before soldering.
The polarizations on the terminals are marked on the battery sticker. (The ones that are not marked are "Ground" terminals)
The polarizations on the step-up regulator are marked on the step-up regulator's pcb (Printed Circuit Board)
Do not short circuit the terminals , ever. (Use hot glue to make sure) (Optional)
You can use any DC battery rated 3.7 volts for this. They are as cheap as 2.50$ for a 3600 Mah rated one
If you don't use the step-up regulator , you will charge slowly and only when the battery on the phone has %30 or less charge remaining.
If you have a question , please ask.
If you have a webcam or video camera , i can remotely help you build it.
If you think i missed anything , leave a comment and i will edit.
I made mine before i decided to make this guide so i will not be providing a video for it , but the users of this guide are welcome to make a video for it , i can put it on my post.
With the links i gave , it costs about 20 dollars to make , it has a 7000 Mah rating more than any portable charger will give.If you use one battery it's 12 dollars. If you use other batteries on ebay it can cost as low as 9 Dollars for 7200 Mah rated charger.
The cheaper ones on the ebay will work just as well.
Links :

http://www.ebay.com/itm/370718295020?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 (Step-up regulator , rated 5 volts)
http://www.ebay.com/itm/3-6V-3600mA...802080332?pt=UK_Batteries&hash=item4609337e4c (A 3600 Mah battery 2.84$ great for it.)
Good Luck.
Cheers!

First , things you make by yourself are more valuable than the ones you buy.
You cannot dump charge with the portable ones.
You'll pay at least 30-40 dollars for a 7000 mah power supply.
It doesn't have to be ugly , i'm planning to make a case out of mahogany , i'll post a picture, see if it is ugly.
Most important of all when you do it , you also learn and you don't throw it away when it is broken you fix it.
Well , to be honest i just wanted to give back to the forum that taught me so much , but now i understand why xbsall abandoned his work...

Yeah this is especially handy if you have leftover spare batteries from old phones.
4 AH is really good for this , more the merrier
But if it is 6 volts you would need a linear regulator or a dc-dc converter like a 7805 , though making a dc to dc converter would be more efficient because 7805 will dissipate a quarter of the power as heat.

A very good question , i'll put it on the main post.
Not at all , it is no different than a wall charger.
The default LG wall charger for Optimus 3D P920 is rated 4.8 Volts with 1 Amp of constant current.
What we made should rate about 5 Volts and 1.5 Ampere of variant current.
Your Optimus 3D's charging mechanism will not accept currents more than 1 Amp so it will regulate it instead.
5 Volts will also be regulated by your built-in regulator to the optimum level which is 4.8 volts , a small difference that is.
sound nice. but as i know 5V by 1.5 A is 7.5W and 4.8 by 1 A is 4.8W. I am not sure but i would expect higher temperature during charging. And according to Li 3D to 2D structure it means shortening the life... As i remember 10 degree difference like 15 to 25 or 25 to 35 degree shorten the half life 1.5 times... well ofcorse this is only emergency process that you suppose (am I right?) and it is not made for every day use.,
ps. i am expert about the Li battery. maybe i am wrong.

You're partially right , it wouldn't however decrease the battery's lifespan because the output will be regulated to optimal levels before it reaches the battery.
Only way to decrease amps is to put some form of resistance in front of it , as it passes through the resistance it will dissipate the consumed current as heat.
So , the resistors will heat up (not by much) but not the battery.
It can be prevented however , by using a regulator with an output of 1A. (Can be found on ebay , radio shack)
Or a less complicated solution ;
A 3.7 volts and 3500 maH rated battery will produce around 945 mA of current , close to the wall charger itself.
So , instead of wiring batteries in parallel , you use one battery.
Another solution ,
Instead of wiring batteries in parallel , you wire them in series then use a linear regulator or a step-down regulator rated 5 volts.
Instead of your phone's resistors , the regulator will heat up
Another one ;
Don't use the Step-down regulator
It will de-promote the flow of current , you will get a really small amount of current that gradually increases as your battery's charge decreases.
However , it will not fully charge your battery , only keep it from going below a certain percentage.
In a good democracy , you never run out of solutions
Hi,
I bought HTC Sensation as a second-hand (used) phone, and I got a charger which has written "Made in China" on it.
Although it does look like the same as I see in unboxing videos, i have some confusions. So, I tried to charge my phone with it and left it overnight. The battery was half charged in that long time and was losing charge percentage if used heavily while charging.
Since then, I did some attempts and notices following results:
>I used my brother's Sony Xperia Arc's charger on my phone and the results (charging speed) are better now.
>I also used Samsung's USB cable to charge via pc and it is also giving good results.
>When I used HTC's (so called) usb cable which I am using for charger to 'connect and charge' via laptop, it shows same result as when connected to charger.
>It was written Charging (USB) when charging via HTC charger and Charging (AC) when charging via Sony's charger.
>I can also see a noticeable difference that HTC's (again, so called) charger has output of 200mA and Sony's original charger has output of 850mA.
I understand that this makes a big difference.
Now, I want to ask that does HTC really give chargers of 200mA?
Finally, coming back to the title, how can I recognize if my charger is fake or not? Any indications etc.?
(I am trying to attach some pictures of it).
Aaaaaand, one more question!
Does battery always drop down by 10-15% or even 30% if I use camera for less than 10 minutes or is 'my' battery having problems?

Thanks for your reply, it's really helpful.
and yes mine also charges very fast till 80% (with Sony charger)
Do you use it continuously and heavily with very short breaks for 8 hours or does it just sleep on standby?
If I leave mine on standby, it drops only zero to 5% charge in whole night. If I use it for like 6 hours while installing apps and browsing via opera mini, it drops down from 100% to 30%, sometimes even lesser.
I bought many adapters from Ebay, and all were fakes, If you would put original and fake charger together you would see little differences like little bit moved logo. Also it depends on cable, do not you longer than 1,5m. I have 2,5m cable and it is behaves as you written, it is too long distance for it, I do not really undarstand it but it does not charge it normaly. Normaly you should buy 1A charger. I bought 0,5A external charger and it has same results as you mentioned. 850mAh should be allright but I thing that best you can do if you are going to use more USB charging ports - buy on Ebay 4 USB PORT charger witch gives really good result and best thing that you can charger 4 things at same time on your cables. I am using it all time. That was best investment in chargers. Price about 7€
All is well HTC phones behave the same way

Thanks a lot for your input. I will buy htc charger because sensation users have told me that the charger is fine and that the problem is with mine only. I don't think that length of cable can be the problem because my SE's charger is a bit longer than htc's and it charges faster. My old Nokia's charger length was also very long and it also used to charge quickly, actually it still does (on other nokias). I will buy from market.

what's 1A ? I have only heard that mAh determines the speed of charger. Is Ampere and mAh similar?

If I leave mine on standby, it drops only zero to 5% charge in whole night. If I use it for like 6 hours while installing apps and browsing via opera mini, it drops down from 100% to 30%, sometimes even lesser.

Don't worry if the battery takes more time to charge aboove 80%, it is due to the electrolyte in the battery....the material used has that characteristic....and it is used widely...it cannot be helped as of now....

yes I know this, if i have 80% charge, I already have enough to fulfil my most requirements..
Hope they invent batteries with more capacity soon

1A is 1000mAh. My charger is a 1A 5v output. 200mAh sounds a little low. Even a USB port is 500mAh.

Hi mate.. Don't worry about original HTC charger.. Numbers on it are lil bit confusing but it outputs 1000mA(1A) so its powerfull enough to charge any phone out there if not broken or st..
Hello,
your charger seems ok, when you carefully look on sticker, there are input and output characteristics. For input you have 240V and 200mA (current is irrelevant for input, it is lower because of high voltage on input) and for output 5V and 1A (you should look at this value of current) which is normal for original chargers. If you have battery fully charged in 2h than you dont need to buy another one. Charging is always faster on the beginning because of higher voltage difference and on the and it slows and probably change charging type so dont worry, it is ok.
mAh is value for capacity (battery capacity based on current usage), mA is for current value (current usage, charging current etc.), very big difference...
mAh (milliampere-hour) https://en.wikipedia.org/wiki/Ampere-hour
mA (milliampere) https://en.wikipedia.org/wiki/Ampere

Thanks for your replies.. The charger whose images I had posted is still sleeping in my drawer because it charged very VERY slowly (yes, it's in caps). I thought that it was original and had some problem in that specific set. So, I bought a same new charger of 1A and I mistakenly connected in on a wall socket which was slightly loose. After some minutes, it started making noises of continuous sparks within it. So I disconnected and tried on another socket without the mobile connected this time. So the charger again produced a big spark which affected the voltage of whole house for a second, thank God it did not touch me. It now rests in garbage. Now I bought same charger again thinking that the loose socket part was my fault, but the same thing happened again when I connected it on another SLIGHTLY loose socket, where all chargers of home normally go. And I got the same results. So then I realized that I am not going to get an original one. Finally I bought a kyocera charger, for 1.5$ (converted amount) which is still working by the grace of God.
First of all . Every night when I go to bed, I like to plug my phone in and charge it while I sleep.
6-7 hrs or so.
Is there a way to stop this fast charge feature , or turn it off. It's a cool addition, however I feel I'm doing more harm leaving it plugged in all night??
Could I just use my old blackberry charger block instead?

Technically , yes you can use any charger you'd like. You don't have to stick with the fast charger. I will though , highlight that the fast charger is optimized for the S6 battery and the battery is optimized for it , so there is no harm in keeping the charger plugged in.
You can't damage the battery if you leave it on all night. All phones have special circuitry to stop charging once the battery is full.
Fast charge works by increasing the voltage, not the current. This is a much safer approach for increasing the power transfer from charger to phone. As it is primarily the amperage that increases thermal output etc.
Although the phone will get warm initially while charging, all phones will. But when the battery reaches full capacity, the battery circuit actually says "okie dokie. I've got what I need now. Let's just trickle charge to keep me full till my boss is ready" and hardly any power will flow through, and the temperature will drop.
Actually makes me wonder about setting up a temp/time monitor while charging to see exactly what happens and when now :3
But as others have said, both charger and battery are optimised for it, and it is plenty safe enough. It's what I do!
There is also nothing stopping you using any other (safe and preferably branded) 5v 1A charger. It will just charge slower. Much like what you are already used to. 3-4 hours instead of 1-1.5ish hours.

Forgive me, I dropped my electrical engineering major, but when we're dealing with direct current, doesn't increasing the voltage by definition increase the current if the resistance doesn't change?
I used the Ampere app to compare the regular charger, from which the phone pulled around a half of an amp, with the fast charger, from which the phone pulled a full amp.

I'm not really sure what you mean by " so should avoid charging the battery is more than power", but battery lifespan in lithium batteries is decreased by FULL discharges and recharges. The best possible routine for making lithium batteries last is to charge early and often. And as genetichazzard pointed out, there is circuitry included that stops the charging (or trickles it) once it reaches full charge.
"Rapid charging", in general, will cost you life in batteries, but that is usually in reference to 4A-6A rapid charging, where this new Samsung charger still does not exceed 2A. I trust their battery engineers. They've one of two things: they have either engineered the batteries and chargers to last in their first sealed body phone, or they are trying to screw us by making a battery/charging system that will force us to pay for a costly battery replacement. They won't stay in business much longer if they go the second route.

I have no idea of the complexities in the technology, or how the phone itself deals with the current from the charger. But I looked at the fast charger that came with my s6 last night, and it is rated like this;
9V 1.67A
5V 2A
The 9V output provides a 15W of power, whereas the the 5V output provides 10W of power.
And after a little bit of reading (can't site my source now as I forgot the website), it is the current that generates heat in the components (such as wires).
So by upping the voltage, the charger is able to transfer more energy to the phone safer than if manufacturers continued to just increase the current.
There will be a smart switching method of some sort within the charger to go from the 5V circuit to the 9V circuit, with a slightly higher resistance to drop the current.
And before I ramble on without making much sense, that is what I have learnt

You are right. Chargers and rechargeable batteries as a whole have been getting "more intelligent" over recent years.
No idea exactly how they do it, I know that a lot of batteries have chips in the that monitor things such as charge capacity and its "health". So I am assuming that they have some form of circuit switch to a higher resistance circuit when the battery is full, so that only a very tiny current can flow, keeping the battery full, without killing it.

Almost always, the circuit is built into the charging device, not the battery. In the case of phone batteries, the phone is the charging device.
Link to more than any non battery engineer needs to know about lithium-ion batteries and charging.

Thanks for the link/info. A while after I said all that, I started thinking that it can't be right.
The phone does the regulation, but I'm pretty they (the batteries) do have an integrated chip for health stuff.
Cheers again for the correction!
I've modified a system file to have a faster charging (3100 mA i've set, like the quickcharge of lg g5), original max current is 2300 mA
For now it work only with screen off in future i try to have this with screen on.
Download attachments
extract it
Replace "thermal-engine-845.conf" located in /system/vendor/etc
Reboot
Device may be more hot than usually because it charge more fast but check if became too hot unplug for a while or restore original file in attachment (high temp and fast charging reduce battery life!)
Now i cant test it because my phone is at service for a mic problem but tell me if it work!
I whold strogly advice agqinst this mod as the creator dont even know the difference between mah and mA
---------- Post added at 07:44 PM ---------- Previous post was at 07:42 PM ----------
And at what Voltage?
If u alow. 3.1A at 11 volts fast charge u might start a little fire.. Most cabls cant handle that and would melt

The stock charger can't do 3A 11 volts so no worries there.
Also on custom roms I was able to get 1.8A 12Volts witch it actually pretty good
Yes but the kernel meshure the resistans in the cable (ohm)
And adopts it current. If u screw with thiis settings and running to high amp on high Ohms the resistans will cause heat....
Thats wye old cable charge bad. Its a security feature to avoid heat by resistance.
Man u shuld realy read upp on this befor postning this

Yea mA, sorry for my error i go to correct
3.1Amps at the battery, doesen't matter voltage trought the cable
It can be 5V 3.1 amps, if cable is good with a low resistance measured by the phone , 9V at 1.7 amps, 12V at 1.3amps with a old cable and not so good cable, so max power is always less than max 18 watts (but better than stock ~ 10W)

I use original values of the lg g5 of the quickcharge so i don't think is so dangerous, i don't touch negotiazion of voltage, only the current to the battery, if a cable is old/bad the voltage rise up to 12 volts to avoid heat of the cable, (but probably more heat to the phone due to conversion) Max power still under 18 Watts

thanks for uploading this setting, it works perfectly on my lg g7. by any chance you don't have a configuration for the thermal throttling of the cpu?
Not Work Android 10
This is not working on Android 10. I already tried it.
Just so everyone is clear, amperage is pulled by a device, not driven by the charger. That means if you tell your device to pull more amps than the charger or wires are rated for, the charger or wires may heat up and can cause a fire, or at least can cause the charger to burn out one of its components. I'm not saying that will happen, but that it can, and you should be careful when trying anything like this. Electricity is awesome, but it can be really dangerous if not treated carefully.
