Hello folks, I am very concerned with my HTC HD2 as it takes like over 4 hours to fully recharge the battery. I have got this HD2 from the market here on XDA and it works very good overall, except for this problem when recharging it. I thought it was the charger and I have tried many usb to wall chargers even the the iPhone's 4 one, but nothing has changed.
I have also tried several roms and kernels but nothing has changed on this side as well. I wiped everything and put back win mobile 6.5 T-mobile stock rom, but hey, no difference here too..
I am wondering if there might be something wrong with the phone itself or can it be the battery going in holiday???....
How can I figure this out???
I have downloaded Battery Doctor from the market and it says the battery is in good health, and I get up to 14 hours with a full charge with mytouch 4G rom and kernel rafpigna 1.7 cpu 1.3Ghz OC.
Is anyone else experiencing the same problem ??? do you guys have any suggests ???
This problem is driving me really crazy...
Get a new battery, mine only takes 2 hours when completely dead.

You think is the battery?? but I get up to 14 hours of usage, I am not sure if its that good though, but I heard this phone is a sucky battery, and anyways why Battery doctor says the battery is in good health ??
Anyways I was thinking to get the battery extended 2300mah
How many hours does your battery last???
Are you using the original HD2 charger? I have tried many different chargers and they always charge at a different rate. It has to be that, not the battery.

Unfortunately it came with its original charger broken and I have never had the pleasure to try with it.. Anyways I am using a charger that has the same specs of the original one, which is the usb charger of the iPhone 4, and yea same result ...
I have downloaded currentwidget from the market and it gets less than 200mA of current in, when it usually should get around 400mA, sometimes the value goes down to 200mA as well, which makes me really wonder the problem might be the usb port of the phone .
Does a broken battery does that as well??

I think it has to do with the charger you're using . When I charge mine I usually see anything from 500+mA to 700+mA on my battery monitor widget depending on how much charge the battery has, and like Segnale007 said it usually takes about 2 hrs to fully charge.

I can't say it's the battery cause you say it lasts you 14 hours, usb port? maybe. Your battery is good for it to last that much (on averge usage of course). It's the different charger that you're using.

The charger I am using its the iphone 4 charger and just like the original one its a 100-240V ~ 0.2A 50-60HZ , which I have no idea about what it means, but I can guarantee u its the same ..
So, what charger do you suggest me to buy?? I wish it was everything except the phone ...

That's your issue there, 0.2A (aka 200mA).
The UK HD2 charger for example, is 1A (aka 1000mA).
To work out the maximum time it should take to charge the battery:
(capacity x inefficiency factor) / charging current
(1230 x 1.15)/200 = 7 hours
(1230 x 1.15)/1000 = 1.4 hours

Oh gosh, so ur basically telling me its the charger I am using what is ****ing up with the slow charging ???
Can you please point me at a good one???
I am totally ignorant about electricity and stuff like that ...
That charger only delievers 0.2 A which is 200ma , you need at least a 500ma charger, mine is a 1 A ( 1000 ma ) and its quite normal to see a 700 ma rate while charging..

Take a look on ebay or any local phone shop/online phone accessory shop.
You want a micro usb charger that has an output current of at least 500mA/0.5A
The original HTC ones are 1000mA.
Blackberry ones I've seen are 700mA so they're good enough.
200mA isn't a problem, it won't damage your battery, in fact it will live slightly longer as it's being put under less stress when charging, but don't use your phone while you're charging with it as you'll be drawing more current than the charger can supply.
So for instance, if you wanted a car charger so you could use the phone as a satnav and talk via bluetooth, you'd need a 1A charger to cope with the drain on the battery.

With very, very light use about 55 hrs. That's not extended.
Alright, my dad has managed to temporary fix its original charger and I can confirm there's nothing wrong with the battery and the phone itself. It gets beyond 800mA with the original charger and fully recharge the batter within an hour and half, which is great..
Ok now I have to find a compatible USB to wall charger with the same frequency.
Since its a T-Mobile US HD2 its original charger is american, and since I am in Italy I'd get an Italian standard wall charger. Does the Italian HD2 original wall charger has the same frequency of the american one??
Thanks

Like many of you guys, I have custom built my own PC. Yeah, it's a little outdated with a Q6600 but it will do for a good year or two more. Good thing I bought a Quad Core. But anyways, getting back to topic, you guys should realize that the Power Output of the front two USB ports are not the same as the USB ports that are in the back. This is a fact as far as my system is concerned. I know because I use a Lacie External drive which will only power on with the rear USB ports.
If you charge the SGS with the included wall charger, it will charge up in about 4 hours. When I leave it on my front USB port, I would wake up in the morning only to find it 60-70 percent full.
PS - I am amazed by the battery of this thing. Here is the break down. I fully charged by 1am. Took it off... then started using it quite a bit till around 3am ish. When I went to bed, the charge was at 72 percent. I work up 6 hours later and guess what, it was at 69 percent. Pretty neat.
The USB 2.0 only requires that a motherboard provides 150mA to a single port (& 500mA to 5 ports). Where as a chargers don't conform to this standard and provides a much higher charge, which charges your battery much quicker.
Only use USB if you have nothing esle.
The wall charger that came with the SGS is a 700mA. I just ordered a 1000mA wall and car charger.
The more I use this phone the more I am amazed by it. The Battery life on this thing is really great. It's already been close to 12 hours (11:30) and the battery is now finally at 49%
I've used this phone quite a bit and the battery held up really well. I used Let's Golf, Navigation, Armored Strike, Calls, Texts, Gmail... Good stuff.
So your telling me if i get a charger with more mA it will charge faster? Where can i get a bigger mA charger.
I don't know, but my battery charges fast as hell. It goes up about 5% in 20 minutes.

5% in 20mins, that's 15% per Hr, or 6.5 hrs from empty to full. You are happy with about 6.5 hrs for a full charge?

will it hurt the battery life or shorten the amount of time you can use the battery if you use a higher mA? because if it wont then why didnt Samsung just include a 1000mA charger with it?

It will do neither.
read this. Gives some basics on Li-ion batteries. link
Essentially these batts can and should be charged at 1C c=capacity. Our batts are 1500mA so we could and should charge at 1500mA.
Slower charging is fine but these batteries rely on circuitry recognizing a drop in voltage to turn the charge off, or down to a lower current as to not damage the battery. If you charge at a higher rate the drop in voltage is more obvious than with a lower voltage and harder to miss thus less chance of an overcharge and battery damage. Added bonus is the battery charges quicker
Over charging is the killer of batteries. Overcharge occurs more from circuitry missing a change in voltage and failing to terminate.
Hope this helps.

If you were an engineer and could save the company one cent, how would you do it? That was about one cent worth of cooper in the charger times ten million devices.you just made your year end bonus.
A dedicated chip inside the phone regulates the battery charge.

700 mA. See the info panel on the charger, it'll tell you.
So a charger with more mA will charge my phone faster i assume? I wont loose any battery capicaty right? It wil charge the same amount just faster i assume?

PID:5139 USB 2.0 A Male to Micro 5pin Male 28/28AWG Cable - 10ft
Very weird thing is happening, instead of charging my phone it drains it .
The battery icon moves back and forth as if it is charging but it drains my battery relativity fast.
5 mins using the car charger I lost 25% of battery life .
Does anyone know why this is happening ?

2 problem is the battery does not last me a full day and i got nothing on it i need a bigger battery asap or i got to return the phone my mytouch lasted longer than thins one please some one help me find a way to get it to last longer or a bigger battery thanks
I am wishing for an extended battery too. Currently, I'm using one of those Duracell pocket lithium ion USB batteries.

Having another device and cable to carry around works, but is a pain...
my battery easily lasts a day. I can get through a full 9 hour day of work and still have 78% battery left. Not to mention I left my phone off the charger last night, got up 10 hours later and the battery only went down 3%
You sure you dont have any programs open? Also I don't use a task manager if that means anything to u

I bought this, it took about 2 weeks to get to me,(but for 12.99 for 2 batteries and a wall charger) as it was coming from hongkong, but got it yesterday, and its great, 2 extra batteries, and a wall charger so now i dont even need to charge my phone, i let the battery die so i can train them right, and just pop in a fully charged one when needed. the charger even has a usb hookup like the original wall charger that came with it, so really you could charge an extra battery, plus the one in the phone through the usb cable. The batteries are the same as the stock one that came with the phone. I wish i would have done this with my G1, instead of spending 90 bucks on 1 extra battery that didnt even have an external charger.

They are Samsung batteries, they look exactly like the one that came with my phone( down to the details written on the battery, only different thing is the date which was from 6/10 where the one with my phone was 7/10 and the s/n number), so I would say yes it is the same quality.

I got the same type of deal on ebay, 2 batteries & the charger (did the same thing with my MT3G as well), it's always nice having extra batteries, and I can use the charger when I'm traveling (it will also charge up my PSP). Now just need to get a mini to micro USB adapter and I have one less cable to carry around for charging - although I recently got an external drive for data storage, so I guess I will need a second cable if I want to tether my phone and use the external drive.
The batteries are not as good as stock and one seems to hold a charge better than the other (have to mark them so I remember which is which - these are generic one without the Samsung label), but as I train them via charge, use until dead, swap, charge, this should at least max them out a bit. The ones I had for my MT3G actually outperformed the original battery that came with so was hoping for the same. But considering how cheap these are, I could even pick up a couple more.

Those batteries from Hong Kong are not an original Samsung battery, they are just compatibles.
The lasting power of a li-on battery depends not just on the mAh, also the circuit inside the battery counts much of it.
The circuit takes care of the special sleep modes and energy saving features of a battery.
Samsung has its own energy saving codes that can not be put into a common compatible batteries.
This is why an original one is much more expensive than a compatible ones.
Extended battery for the vibrant, lasts twice as long and great door
Check this out: Moretalktime's feedback is 100% and the door is soft rubberized--better than stock IMO. It cradles well in your hand in a very comfortable position and lasts over twice as long.

Re: Batteries not lasting all day
I'd like to throw in an observation on this thread. My battery life is quite good on my Vibrant. Lasts all day easily but there are a couple of things to take notice of. First, I do not use any task killers or such, but I do check if there are any running programs with the built in task manager and stop them once I'm through with them. I've found that Voice Search and Web Access continue to run even after I've closed or backed out of them. Thus the need for use of task manager. But here's what I really found out. I've always charged my phone using the wall adapter with USB cable plugged into it. Never had a problem with battery life. Then for some reason, I decided to start using the USB cable attached to my computer. It would charge as normal and each morning it showed 100% charged. But after about 1 week of using the USB cable from the PC to charge the phone, I started having the horrible battery issues that I've read about. Extremely fast discharge. Leave at 8am and have like 50% use at noon. Crazy. So I started using the wall charger again and the phone has returned to its original state, easily lasting all day. Just a heads up for some of you guys having battery problems. No idea why this has happened but I've confirmed it. Maybe the Power Management thing on the USB ports on the PC?
I just saw this thread after a search on Google. I already posted elsewhere, but this looks like it might be the battery some of you are looking for.

If nothing else, they also sell a 1600mAh battery which is 100mAh larger than the stock battery and still fits unter the stock cover. Good Luck

Hi
Using today the phone @ 100% brightness with car charger connected and using Sygic / Copilot, I see that my device can't not even charge at the same time that I am using it, but maintain their % of battery. Even with the charger the phone drains battery.
WTF samsung, So i cant make a long travel without running out of battery?
Anyone more with this problem?
PS: My HD2, HD, TyTN2, etc doesn't have this problem with the same car charger, they even charge at the same time.
What's the rating on your charger? I had to swap mine out for a 1A one in order to cope with GPS use in the car. Haven't had a problem since then.
I suspect the one you're using is 750mA or even potentially 500.
I have just had the same problem. I knew i needed a higher amp charger but i thought i would give it a try. The one i used is 650mA, so that's definitely not large enough. The normal 'house' charger is 0.7A (700mA) so in theory that size or above should charge whilst the S2 is being used.
I have a 1200 mA usb adapter for car (a sony ericsson, very very slim one) and I have no issues. You need a decent amount of power for that phone so 650mA will not do, have at least 1000.

Not sure if this is the exact model but I found it to be the best because it's slim and there is nothing sticking out of the car socket, has a lot of power and I can power any usb device with it.

Yest but probably you hava a chinese charger. The rating on it is never near the real one.
oh, I see, crappy charger, ill change then thanks guys
TomTom recently released a high speed multi charger. I replaced my old car charger with this one as I had a similar slow charge problem. Never had a problem ever since. All my weapons are always fully loaded with enough power! Expensive though!

If someone is using a cheap higher-powered mains adaptor without issue, could you please post a (UK) link? Also if anyone knows of a cheaper alternative to the £20 car charger that would be great too!
I had same problem.I bought Samsung charger and no problem after

2.1 Amp TomTom charger is way too much for this device. Samsung wall charger is only rated at 750mA, but someone even found out that in source level Samsung has limited the power current at only 650mA.
With 1 Amp (1000mA) top quality car charger, the phone lost charge while using Navigation on full brightness.
Very slow charging in general for this phone.

When you have the car charger plugged into the phone go into Settings/About phone/Status & look at "Battery status"; it should tell you if the phone thinks it's plugged into a USB port (in which case the phone will draw only 450 mA) or an AC charger (from which the phone will draw 650 mA). These limits are built into the Samsung ROM, presumably to keep the phone cool and/or extend the battery's lifespan. They could be overridden (especially the AC charger current limit) in a custom ROM.
Absent a custom ROM, if the Status display says you're connected to a USB port, you could try a different charger, or connecting USB pins 2 & 3 (the two center pins on the USB A connector) together. That's how the phone decides if it's connected to a USB port or AC charger -- the low-resistance (less than 200 ohm) connection between the two USB data pins is the key. The spec calls for 200 ohms resistance between the data pins, but some of the low-end high current chargers I've seen just have a direct short.
If that doesn't work, or if the Status display says you're charging off AC, then try some of the other battery-life tricks documented here in the forums; they should reduce the device's draw from the battery, allowing the charger to do its job.
Wow, this is kind of disappointing i have to say. I have noticed the USB charging is incredibly slow. You can't ever rely on it, i think it would take close to 5 hrs to fully charge from USB, that's insane! By mains it's somewhere between 2 and 3, but that's still way too high.
I take it if you buy a higher-powered mains adaptor (not one for the car) then we'd definitely get the benefits of a faster charge? Can someone post a link to one they are using and know works faster that the stock one?
Cheers
I ll try ur tricks guyz.
for the time being this is my situation (and it sux):
-car charger 1A 5v
-slow chargin and hot device
-using navigator equals : phone burns, drains battery and in the worst scenario freezes
yesterday I received a call while phone plugged into car charger with navigator session. wot happened is phone freezed (screen didnt switch off) and I saw PROXIMITY SENSOR WAS RED!

The first post got me worried for a while, but this info has put me back to ease. Pre-ordered the GS2 (India) and getting the original Samsung charger along as a freebie.
Yeah, i have simelar experience with the samsung s2 in my car.
Its eating the battery even when its plugged in and i think i have a good charger..
I found 1 solution.. I use now copilot, you can set different setting to disable the screen automatically when you drive a straigt forward for some kilometres, only when you need to turn it comes up again.
thats how i set it and it loads a little, but bad anyway.
Maybe thats what the + means in Super Amoled + (+batteryusage)

★★★This topic is for them who are having problems with stock charger and cable. If you don't have any problems, ignore this ★★★
Well, since I purchased my Note 2, I kept facing this slow charging problem. Now what is slow charging some of you will ask? Well, it's simple. The device is taking more than normal time for charging. Now how do you know the default/should be rate for charging? Simple again. The AC adapter clearly says output rate as 2000 mA or 2.0 A. So with that calculation Note 2's monstrous 3100 mAh should be fully charged with 2 hours. But as we've seen steady 2.0A is not the output case in some/many scenario, so add another 30 mins to it. So whatever it is, from 0-100%, the device shouldn't take more than 2 hours 30 minutes.
And for me, it was taking around 5 hours! Sometimes 4 hours 30 minutes, and if it's very fast then 4 hours. Well I was never gonna wait 4 damn hours before going to my office and irritate myself, and I don't have the habit of charging overnight, unless I absolutely need it.
So I kept calling my retailer, asked for replacement, and they did, well, you won't believe, they replaced three times actually, so I had three different Note 2, with three different charger. Well, each of them acted absolutely fine at first 3-4 charge, then the problem was back again and again. I in fact turned off the device and put it into trash once.
Then I thought let's try some different USB cables, I tried my friend's Galaxy Ace cable. Charging current kept fluctuating between 1000-1200 mA. Which was better than those faulty stock cables, which provided steady 900 mA. Sometimes it even was detecting the AC current as USB, which would provide a mere 460 mA and would take God knows how long! Then I found my piece. I went to my retailer, frustrated and angry, asked them to give me the thickest and shortest possible cable, and they provide me one from a Samsung phone's box, but I can't recall which device was that! And then I sat there for half an hour, kept plugging and unplugging, and the current rate was rock steady at 1800 mA. I took it, paid just 10$ and came back.
Since then I have charged my phone almost 10 times and the current rate never went below 1800 mA / 1.8 A.
This is the cable I am using, do notice that it has 5 pin set up against stock cable's 4 pi, if that matters in any way, and it's about 10% thicker than the stock cable and also about 9" shorter.
And how will you monitor the charging current, three ways are there,
1- Battery Monitor (yet I don't know how to exactly use it)
2- If you are rooted (which is a must anyway), then just go to, /sys/class/power_supply/battery/current_avg
3- Use the app from the link below. It basically reads the current value just exactly as above but it saves the time to go into that file every time. A big thanks to Deadvirus.

Same here, it's done within about 2 hours every time, from ~1%. Something definitely must have gone wrong with yours :s
R: [SOLUTION] Slow Charging!
You are amazingly right. Every charger/cable combo I test seems to deliver different currents, according to the app you posted, ranging from 600 to 1300 (mA?).
Didn't know that could happen. Now I am looking for the Holy Grail of chargers, too.
After some tests: original chargers of Note 2 and Tab provide 1800 mA; no-brand Chinese labeled 1500 gives 1400; one Nokia labeled 1200 gives 1300, another, labeled 1200, gives 1200. Puro brand, labeled 2100, gives 1100. Another Chinese, no-brand, labeled 2000, double usb, gives 1100 per socket. Other no-brand samples give 600 or 300 mA.
Enormous variability.
Think I'll use the 1800 mA Samsung for when I'm out, and the good Nokia's for overnight charging when home.

Thank you for nice explanation! Now it's much clearer.
For me...
Stock charger + stock short cable (0,9 m) = ~2+ hours
Stock charger + some other cable (1,8 m) = ~4+ hours
,don't know about thicknes. Mb stock cable is thicker, or at least harder to bend.
Sent from my GT-N7100
Thanks for the APK, I found a huge variance in charging rates based on a combination of chargers and cables. Goes to show that the cable makes a huge difference. Here's my findings:
** Stock Charger (2A):
w/Stock Cable (4-pin) - 1698
w/Cable from another phone (5-pin) - 1698
w/Cable from battery pack (5-pin)- 1698
w/generic eBay cable (4-pin)- 100! - It didn't charge at all, even with screen off.
** iPhone Charger (1A):
w/Stock Cable (4-pin) - 1300
w/Cable from another phone (5-pin) - 1100
w/Cable from battery pack (5-pin) - 1300
w/generic eBay cable (4-pin) - 100!
** Car Charger (1A):
w/another generic eBay cable - 490
(Was running Redpill kernel, not sure if that has fast charging built in which might affect results).
The app is really helpful. Been wondering what the charging current was on different chargers.
I measured it using the app based on current AVG and not current NOW. This is because I used a 800ma blackberry charger and yet current now shows 1698 which is impossible.
The app will tell you which cables and chargers are good. I was shocked that out of my 8 cables only 3 gave an average of more than 1000, the rest give around 800 or less.

Hi!
So, the AC adaptater mentionne 2A but it doesn't mean that your devuce consume 2A... It means that the AC adaptater can provide 2A under 5V.
If a load need to consume 500mA the adaptater can provide enough power. But if it needs more than 2A, the ouput current will be at the 2A max but your voltage will decrease (it means that you have a device problem!).
The only thing to do is to refer to the user manual of device.
One thing more, the USB protocole fix the maximun current to 1A!
An other thing, if you want to have a better battery life it recommended to charge your battery slowly. Just have the habit to charge it during the night.
See ya.

Yes, the stock charger doesn't provide full 2A current.
And is it true that if the device is charged slowly the battery backup will be better? I mean that would be good then. I'll try that, thanks for informing.

On my old cable, the damaged stock one, it'd take half an hour to reach 100% from 99. With this one it takes 5-6 mins.
This whole charging process is complicated that much I can say.

Unfortunately I got a grey import so my stock charger was for a different country.
I'm having to use a 1.0A charger instead.
It still only takes a few hours to charge though. I sleep for 4-5 hours and it's always fully charged when I wake up.

I don't know what drug Apple put in their chargers, but i've always noticed my iPhone charging waaaay faster than my S2.
I even tried draining them both to 0%, and charging them with their original chargers. As soon as the iPhone was full of juice, the S2 was just about 50 or 60%
So i did some research about the safety of using the Apple charger, and it appeared to be all OK.
I'm going to end up buying a new battery anyways because i feel like mine has worn out, so i thought it was a good idea to plug the S2 in the fruitplug.
After i plugged the USB cable into the Apple charger, i immediately noticed the phone charging way faster. Waaay faster.
The phone does get a little warmer, but not too warm. I charged the phone from 8% to 100% in less than a hour!
I'm still experimenting the safety of this, by constantly keeping a look at the temperatures, and how hot the thing feels, and it appears to stay safe.
I recommend to remove your case and battery cover and keep an eye on your phone if you consider trying this, but for now i can say one thing:
If you have an iDevice in your house, charge your phone with the fruitplug
on the other side... what do you think about it? Would you try it?

According to the information on the charger, it outputs 1A. My samsung charger also outputs 1A, yet it charges faster with the iPhone charger.
I did some quick research and found that the iPhone charger would have a special sort of **** inside of it that charges the phone in a different way. Not sure if bull**** or actually true, but they did put some sort of magic or drug in that thing to make it hypercharge anything i charge in it
They couldn't have put anything inside, it all depends of voltage and amperage.
You can use charger with higher amperage than your device need though.
And, yea, you can use charger with more amps, but you cannot use charger with higher voltage than 5V.
iPad charger gives [email protected], but last time I tried it with a Samsung phone, it wouldn't charge.
Nightshadow931 said:

The higher the amperage, the faster your phone will charge.
You can use charger with higher amperage than your device need, your phone would charge just fine, only faster. But it would cause heating your device, thus reducing the life of your battery.

So 650mah, and a 1650mah battery, that means 2 and a half hour for full cycle. And that also means something is happening to that apple juicer

This.
S2's hardware doesn't allow it to charge more than 650mAh from an external charger. So it doesn't matter if you're using 1Ah or 2Ah charger, it will be the same.
Now, that's for the international i9100, who knows if there's something different with other versions or if the phone has a faulty hardware. I've also noticed that my phone recharges much faster right after being quickly discharged. So it could also be that the metering is faulty and there was juice left in the battery.
