battery charger?

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!

Phone overheat when charging.

Does anyone know why does my phone always overheat when I charge it? My wifi is off, and basically killed all my running apps.
This doesn't happen on my friend's nexus one.
By the way, I'm on FRF91 at&t. Anyone mind helping me with this? It would be greatly appreciated.

What do you mean by overheating? Like turns off, bursts into flame, "feels hot"?

There's greater heat if you charge via USB as opposed to the wall charger. Did you both use the same charging methods?

Why does a usb cable heat up more than a "rapid charger" i thought the usb charged half as fast.
It would be logical to assume that less energy would produce less heat,
Please explain

Mine was also cooking on the charger. But after I switched to undervolted kernel the heat is not as high anymore.

I believe that the reason would be that USB has constant current, while rapid charger "pulses" the current, making the charging much more effective.

How do you undervolted the phone?
The temperature of my phone can go up as hot as 41C when I'm using the wall charger. But I charged it using the USB cable, it does not get hot at all.
So, is it possible that my wall charger is broken?

Only 41C? Don't worry about it then.

41C is nothing to worry about really. You should only be concerned if it went over 60C and even then it's mostly the battery that's paying the price.

Ah well... All my previous phone never reached that hot when it's charged.
I'm relieved that it's normal to reach 41C when charging then.
Thanks guys.

Yes, there is a difference. Since the capacity charge is definitely different (5 V @ 500 mA vs. 5 V @ 1 A) there needs to be some sort of transformation in the power supply of the Nexus One. And transformation always releases heat.
Since the Nexus One and the Desktop Dock ship with a charger, this seems to be the preferred charging method and it makes sense that the phones power supply was designed to reflect that.
From my own experience I can say that my Nexus One get's very hot when charged via USB and almost no heat increase occurs when I charge it with the wall charger. But there might be a difference for users with 110 V ~ in their sockets.
Also check out the Li-Ion Battery guide, krad1992.

I also noticed that the phone gets a little hot when charging it. But I think that is natural. Also, it wasn't as extreme as you put it, where it would "overheat," instead I could notice that the phone was warmer when placed in the hand, especially in the lower bottom corner. But it never overheats...

If the heat worries you, you could always installed SetCPU (on a rooted device, of course) and set a profile to scale the processor speed down when charging, and I believe the newer versions of that app even let you set a different profile for charging via USB versus AC.

OMFG, nonsense FUD. 5V is 5V. The phone only draws 500mAh when a 'USB' charge is detected, vs drawing 1Ah when an 'AC' charge is detected. The power supply is not pushing power into the device.
I'm not disagreeing that your phone gets hot when charging with a slow charge, but your assumptions are total nonsense and it's not normal.
Maybe you have some software doing something weird when USB is plugged in charging.. Ever tried shutting the phone down and plugging it on USB and seeing if it also gets hot?

That might be a little harsh...
My phone ALWAYS gets hotter charging from USB (and especially from a USB cable plugged into a non-HTC 1, 1.6 or 2A wall charger).
The phone detects whether it should be in AC or in USB mode based on whether it a couple of the pins are shorted in the cable (this has been confirmed by people taking hotknives to their chargers). If it detects USB mode, it only draws about 450mA. In AC mode (thus, if it sees shorted pins, like in the stock HTC chargers), it'll draw somewhat (slightly) less than 1A.
I think that imperfect quality control or imperfect engineering on the phone might cause some drawn current to escape as heat when in USB mode, but not to while in AC mode.
This does not (at least for me) seem to be a software issue, because I have seen the EXACT SAME BEHAVIOR on CM 5.0.5, CM 5.0.6, CM 5.0.7(.x), CM 5.0.8, FRF50, FRF83, FRF85b, FRF91 and CM6 (both nightly and RC1). I've tried out dozens of kernels, and the problem seems to be a LITTLE better on more fiercely UC'd versions.
Plugging into USB and charging ALWAYS causes my phone to become warm or hot to the touch (after 30min to 1Hr, of course). After a good while, temps go on up to 34-39 on USB, with very little user activity or screen use, versus 29-32 when in AC mode. I have never had the slightest PROBLEM linked with this issue - that level of heat just isn't bad for something designed to work in the sun, sit in your pocket all day, etc.
I can confirm that this is also a problem on an HTC Desire - both the IDIOTIC self-limiting AC/USB regulator and the heat-while-charging-USB issue.
The AC/USB logic used by the phone is the most user-unfriendly thing I've ever seen on a phone, because it is MUCH too strict. It is solely designed to get you to buy "official" HTC fast chargers, rather than letting you use third party gear.
My Milestone would charge (and draw) fast from any old wall bump that could feed enough juice. iPhones do it. My BlackBerry Bold would draw well over 1A and fully charge in less than an hour off of anything that fed enough juice. But my fantastic "superphone" can't do this? That is really the ONLY thing I don't like about the N1 - and it will probably stop me from ever buying an HTC phone again, since I have confirmed exactly the same behavior on other models. Here's why:
If my wife and I travel with our kids, with multiple USB-charged and powered devices, I either have to bring both my US-only N1 charger AND an adapter (we live in France) PLUS another USB source (like a 2-in-1 or a 4-in-1) and cables, OR I can just bring the other source and count on 7 hours a day with my phone plugged into the wall, since 450mA is crap. And all of this is because HTC wants me to buy and use their chargers - which do not accept USB plugs like Moto's, Apple's, third-party, etc.

Well. Mine is the other way round. When I charged it with my USB cable, it doesn't get hot at all. But, it gets very hot when I charge with the wall charger.

You voted yet? My results from today are even lower than that of yesterday, but my house is colder than my office.. Wife likes it frigid.. 27C charging on USB today.

Maybe you are using the phone while it's being charged, thus using the processor and producing heat?
I can leave mine on all day, and it doesn't get any hotter than a regular phone being charged. But if I have the OLED on and using processor, then it gets a little warmer.
The hottest I've seen mine get of 47 c, and that was because I was outside at the pool and the sun was killing it lol.

Though your slightly unkind post was answered sufficiently by big_adventure, I'd like to add something.
I suspect we both don't know how the input circuit of the Nexus One is designed, so it's pure speculation when we talk about how the power input is handled. HTC can be quiet fast with their hardware iterations, so we might even have different revisions.
But, the Nexus Ones Li-Ion needs a current of 1.4 A (1 C) until 4.2 V cell voltage are reached, ideally. The power the AC wall charger delivers fits in quiet well with almost no transformation. The maximum current the USB port can deliver is way out of the ideal range so there's the need for some more sweet magic in the circuits. And sweet electronic magic is connected to releasing heat.
However the input circuit is designed, there are definitely differences how the input of both charging methods is handled, causing varying levels of heat increase. Depending on what the engineers chose as their bias point. Tolerances have impact, of course and hardware revisions might have changed things. I'd like to be more specific but I have never designed a mobile phone charging circuit nor do I intend to disembowel my N1 for the sake of an argument
Caution: You may find speculation and assumptions but no FUD
Take care.

Can Milestone charger be used for OB?

I'm about to use a Moto Milestone 1 charger for OB but I'm afraid that it may harm the phone. Both phones are listed with MicroUSB 2. Any tips?
thanks

Don't worry.. it will work Ok, but OB charger has 1000ma, if you use another charger that has let's say 500ma (like USB) it will take 3 hours to charge the phone instead of the regular 45 minutes!
I use a samsung cable directly from USB, the car USB port, a samsung 5530 charger, a LG optimus one charger, and they all worked, with various degrees of effectiveness!
The most useful one is the car's USB port that, even if it cannot keep up with the GPS (it charges slower than the battery drains), it can keep the phone running with 10% loss every hour with screen activated and GPS at the same time! The problem is that I hate radio and don't use CD's that much, and usually end up with the phone depleted before I reach the destination!

Thanks man! Ok I'll check that "ma" thing. BTW is it written on the battery or charger?

Both places; battery specify working and standby V and mA, charger specify the V and mA provider
So you can use almost every different charger if the specs are the same, but be aware of this: don't use a charger with less mA since it can burn the charger

Ma - miliamps.
How many milliamps in 1 watt/volt? The answer is 1000.
I assume you are converting between milliampere and watt/volt.
I never had a burnt charger by the way, that would be very strange considering that the phone is accepting 500ma from the start (that is the USB output on any PC), and I even saw chargers with a power of 2W (SUPER FAST CHARGERS). The Motorola chargers are 850 ma usually, so it should work quite good!

Indeed, it's very strange to have a burnt charger and we don't need to go into an electrical discussion but that happens because of 2 possible things, very high-peak of voltage or prolonged use of under-voltage

Thanks. Printed on my Moto charger is 850mA so I'll rather use it for my OB next time.
BTW, currently I'm using a replacement charger for my OB with a name "super charger" printed "4.5v - 9.5v 800ma"
It's charging at normal duration in fact I'm using it for days. The only problem is that my OB touchscreen freaks out if I use it while that charger is connected. It's obvious when I run the multitouch testing app because touch points run all over the place. Touchscreen goes back to normal if I disconnect the charger. I tested that "super charger" to my milestone and the same abnormal thing happens to the screen. What causes it?

Probably it's something to do with high voltage... I'd avoid using it if something like that happens to my phone..
Usually the USB style chargers are pretty standard... the speed with which they work are strongly related to the power (Amperes) they provide, the voltage "should" be pretty standard!

Battery experts say to try and use a charger that's rated half the power of the battery.
So for a 1500 mAh battery, a charger of 850 mAh should be a better option than a 1000 mAh one.
Yes, the 1000 mAh charger would charge the battery faster than the 850 mAh one but it will decrease the lifetime of the battery faster.

Just for be able to post new thread. Sorry.

Hello, I don't want to start a new thread so I'll ask here.
The charger that came with my OB seems to be damaged. It was working properly until last last night. My phone detects the charger but it won't charge. Got powermax turned on and it automatically turned off when I connected the charger, so I know my charger does have issues.
Tried banging the charger last night, connected it to phone and started charging, woke up to see that it stopped charging 2 hours ago. It didn't even fully charge my phone. Now I'm charging it with my pc via the USB cable. I noticed that the touch screen goes wild when I use it while connected with the USB.
Now, I'm planning to buy a Galaxy S2 charger. Is it safe to use? S2 and OB has almost the same battery capacity so I'm considering it. Any other suggestions? OB ain't popular here in the Philippines so finding accessories is a real pain in the a**.
Fitted a Corby 2 charger and it seems like they use Mini-usb too. Haven't tried charging with it though.

My original charger also died... Now I use the one that came with my bluetooth headset
So I guess using the OB charger on other stuff is okay too. USB is always ~5v.
You need to test the charger with something else to be sure, though.
I had the same touchscreen freaking out problem with my old LG KS20, whenever I charged it. Like it was shorted or something. So it maybe a problem with the phone itself.

So, you agree that I use a Galaxy S2 charger? I think it would be fine since my friend with an S2 used my charger to charge his phone and it went well. I'll ask him to buy me one tomorrow. Tnx for reply

Ok kabayan, don't forget to share here the result after u try gs2 charger. I too am looking for safe alternative to my milestone charger.

Standard port - standard voltage
Don't even bother, if it has a micro USB it should be fallowing the same standard as USB for charging (5V)...
Of course test the charger for any adverse side effects like screen flickering or short battery life, and don't use it if something like that occurs, but because of the standardized voltage and the fact that usually phone chargers have between 500 - 1000 mA, 99% of chargers work...
I still haven't found any incompatible charger for my phone and I don't even buy a phone if it has a non standard Charging/Data Port... it's just stupid... so no Iphone for me!

Hello guys! I'm here for an update. For the past week I've been using a Corby 2 charger. And guess what, it works just fine! only downside is it won't charge it up to 100% (usually gets to 99% upon unplugging). And it charges the phone a little slower than the original charger. I always let the phone overcharge overnight to have 100% battery.

Can it cause any damage if using a 2.1amp wall charger instead of the original 1.5amp ?

I think the phone charges how much it needs/set. So if you give the bigger charger it can be that the phone doesnt charge faster. But i'm not sure also my explanation is bad I know
" So if you give the bigger charger it can be that the phone doesnt charge faster."
So it will not damage something. That I wanna say with this sentence
But for a 100% correctly answer an other person have to give an answer like a dev

The phone SHOULD only take the charge it needs, it has an auto cut out when the battery is full so it won't overload and damage the battery.
Charging amps is a funny business. A 1.5 amp charger on a ten metre cable will be practically the same as a 10 amp charger straight into the phone. You lose energy through the cable. The cable my dock came with is rated 2.1 amp but the charger itself is only rated for 0.5 amp. So it takes forever to charge, till I plugged a 3amp charger in, it charges at the same rate but the phone gets much hotter.
I dunno, I just stick to keeping the amps and cable ratings the same as the one that came with the phone in the box. That way we know we can break anything:good:

Is there something that can be done to fix this ? has anyone found a cure yet ? (other than dipping the phone in water to cool it down)

Ignore it, the phone will automatically shut itself down to protect itself long before the temperature is high enough to actually cause it any permanent damage. It's actually nice in my profession, warms the hands on freezing cold days.

[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.

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?
