why my dash charger is slow sometimes is in 3500 ma and sometimes is in 2400 mah , it happens also when I have 30% or 50%

Cool down phone..
I have seen this as well depending on the plug is turned. I get dash charging on one side but slow charging on the other.

power saving battery charger:
I want to buy this battery charger,
because I've buyed my HD2 from GB (I live in Germany)
and the plug doesn't fit
But I have some doubt about the specs:
ORG: 5V, 1000 mA
this: 5V, 1200 mA
will this make problems?
Sure this would be fine!
Should work fine. If it doesn't fit try finding an adapter. They aren't expensive these days.
Doesn't it matter what the power output is for the charger? The mah rating, or anything or are you guys just saying that any charger with a micro usb on the end will work and that the phone itself will regular the power?
Your phone needs 1000mA minimum, 1200mA is 20% better It will work very well with your HD2. If you don't like it, pass it on please, I'll take it off your hands

That's not correct, you shouldn't really be going over 1000mA, I got a micro usb charger off eBay for 1.75GBP and its rating is 650mA and it works fine.
So you can safely charge your phone with a 700 mah rating, and it will just charge slowly but will not negatively affect the battery life longevity or harm the phone correct?
One person said it has to be a minimum of 1000 mah, so that makes me worried of going below and using a 500 mah and having my battery get screwed up, or the unit blow up.

Used my cheap ebay USB wall charger rated 500 mAh... worked for a week, now it's dead..just wouldn't charge anymore. Good thing the charger didn't blow up..lol

You can go below with no problems but there will be a minimum amount the phone will need to charge. My post above was incorrect about the charger i got, its 550Mah not 650Mah and still going strong. When purchasing chargers off Ebay i always buy from my home country, that way if anything untoward goes wrong i can go knocking on their door!
on chargers
what u guys should watch out for is the voltage not maH. 5V is what we need to pay attention to. If you use a higher voltage the battery will explode.
The difference between 550 mAH or 1200 mAH is the charging time. With 1200mAH your phone will charge quicker vs the 550mAH. Just think of it that you are trying to fill a pail with water. 550mAH is like using a small straw. 1200 mAH is like using a big pipe.
Hope this helps

This has been the most useful post in this thread thanks....
So, I have a Motorola charger for my BT headset that is rated 5V and 550mAH... I assume I can charge my phone with this safely without any adverse effect on the battery (just a slower charge)?
Makes sense as I think charging VIA usb cable and a laptop also takes longer... This would be great as I have a few of those motorola chargers lying around and won't mind using them for bedside overnight charging... it will free up another micro USB cable for me
I am assuming it will be ok cause USB charging from laptops/computers are about 4.7V at 500mah.... This means this little charger should be ok I think... I have ALWAYS left my phones connected for long periods of time to laptops/PCs... does not seem to affect battery lifespan. Can anyone confirm this or tell me differently?
im the "drop out"
yep looks like im the "drop out" i got coming from HK its only 350mA and even befor it arrive i look for another.
I see espansys have one 1500ma AC Adaptor but very expensive > but i suppose if want battery to last > good to get
So, I used my Motorola charger for my HX1 bluetooth headset to charge my phone overnight (with phone on). The only thing running was SPB time with an animated background.... The charger is rated 5V 550Mah..... all seemed to be fine at the begining.
However, this morning, I work up to a blank screen and the fully charged LED on. Even after unplugging, the LED stayed on and the phone was unresponsive. I had to remove the cover and pull out the battery to restart. I am wondering if it was the charger or perhaps SPB time? I will give it another go tonight without SPB Time v3.1.1 running to see if it does the same. I hope Im not destroying my battery!
Edit: I charged it last night from 5% till full with no SPB time running... no problems cool!
After I read several infos about this topic ...
Is that true that the Nexus S has limit of the amount of power it takes from the wall charger?
Suppose, it has limit of 750 mA.
Even if we use 1000 mA or 2000 mA, the Nexus S will take 750 mA during charging.
So, having much bigger mA charging rate will NOT speed up the charging time.
Am I correct?
Yesterday, I checked my Nexus S during wall charging:
65% charged at 01:57
87% charged at 02:48
So, it is about 22% per 50 minutes.
100% = 227 minutes (3 hours 47 minutes) ... almost 4 hours.
No task was performed, except turning on screen to check batt %.
And I was using HTC Desire charger (5v 1000 mA).
How long is yours?

Using an iPhone (1000mA) nubby it takes sometimes over four hours to charge mine
It definitely seems limited to me - though it seems that 1-2A chargers do cut 10-20% off of the charging time of the .7A stock charger. I said 30% in another thread, but further testing indicates that's not the case. Maybe the limit is around 750 or 800mA, and the stock charger doesn't really give .7 ?
if you want to charge the battery real fast
don't charge inside the phone
use a Wall charger for the battery, and it charges 100% in a little over 2 hours
the ones you find on eBay or Deal Extreme
find the ones that charges at 1000 mAh
you wont find any wall chargers for 2000 mAh (only available for cars)
the highest i've seen for wall is 1200 mAh
in my case it came in a combo so i got 2 extra batteries + wall charger

Could you share the ebay link please? Thanks!
I've noticed that if I try to charge my razr I with my car charger (2000ma USB griffin cigarette ) it charges quickly.
If I try the same with my ipad charger it seems to go really slow?
The ipad charger should also output 2000ma so I don't know why it's charging slowly unless the razr i is limiting the amount of current it is drawing?
Bigger battery, more charging to do. One guy, somewhere on here, posted a chart showing the speed and duration of his charging. It took about 2 hours for a full charge. Know that generally, phones are made to accept a charge faster for the first 30/40/50% of the cycle and to charge more normally after that.
You just have to make some counts. The charger charges at 900 mAh. So you need 2 hours and 10 minutes (more or less) to charge all the 2000 mAh battery. Maybe you use a different charger that charges more mAh.
i am using an app called battery monitor widge from the play store t and have logs for the past day .
its showing different values when charging with the stock HTC charger.
Not sure if the phone or battery circuit does this , it seems the charging on the htc charger is on/off... like charging in pulses
sometimes +600 mah, stops , sometimes _ +300 mah stops , sometimes - xxx mah ...
i think its trickle charging they say the phone trickle charges after 80%. but the prob here is on the HTC charger the charge is fluctuating even below 80%
i tried a note 1 charger which has the same rating as the HTC charger. same behaviour
so it tells me the battery does not like 1A
then i switched to a 700 ma samsung charger . so far it shows a constant current of 800 mah...there is no on/off behaviour
and there is a constant charging current applied except that around 90% onwards the charge tapers off
I seem to recall reading something on the web a long time ago that said that charging at less than 1C could actually result in a faster charge to 80-90% charge.
The rationale being that if you charge at a higher rate, it forces the voltage up to the maximum faster and then the charger has to ramp down the current faster.
If you charge at say 0.7C then it takes longer for the voltage to hit the maximum and then, counterintuitively, the average current for the duration of the charge is actually higher.
I am tested this theory now... but it seems like it could be true.
using samsung charger rated @ 7C and using the battery monitor app, the samsung charger is keeping the phone charged at a constant 700 mah but the HTC charger is fluctuating from 500+ mah to 600 mah ten sometimes to 900 mah
not sure why the samsung charger seems to charge the HTC one faster than the HTC charger..
cant explain why though
They say there are different chargers behave differently with different batteries.
can someone care to share some light here?
is the HTC charger defective?

Even I will like to know. I have been using the blackberry charger for charging my HTC one. The charger is rated 5V, 700 mA. Is it safe to use it permanently with HTC One.
I've seen the Qi-Infinitiy 3 Coil Folding, the Choetech T511, T513 and the TechMatte, is there a preferred brand? from a quality and performance perspective?
What should be the average time to fully charge the phone from an almost empty battery? right now I am at 40% aprox and it says around 2 hours to fully charge the phone,
Thanks a lot
This is what I bought Mikobox it has been working great and it was cheap. I leave mine on the charger overnight so I don't know how long it takes to recharge when at 40%?
I bought the Aukey Luna first but found it wouldn't charge the phone to a 100% after a week and after a few weeks it was only charging to 90% so I sent it back.

Dewnload Ampere so you can compare charge rates more accurately. I get anywhere from 500 ma to 700 ma when qi charging at home
Using the Tylt Vu. Very easy to line up. Works through cases & seems to charge quickly. I've been extremely happy with it.

I just checked mine, is at 75%, 879mA and 4.27V, the temperature is 94F. I am using GSam Battery Monitor Pro to measure the Amps.
I am using the Qi-infinity 3 Coils Folding Wireless Charger
I get 750 ma using this charger:
http://www.amazon.com/Itian-k8-Stan...249729&sr=8-9&keywords=itian+wireless+charger
With either rinkge fusion or TPU case. Also almost the same size as N6; works great
I forgot to mention that I have a Nillkin Super Frosted Shield Matte Hard Case Cover installed in the phone, that might affect the performance of the Wireless charger
...
I have been using a Choetech Stadium since January. Bought one for work too. Never been more happy.
