Is it me or everybody else. My charger heat up. its like it will burn my skin if i touch it. and it take 2+ hours to charge phone from 0 to 100%.
That is absolutely normal to take 2-3 hours to charge the phone fully from 0-100. Also charger heatup is normal too, but it should not be too high. You can check if the electric socket is good or maybe change to different electric socket to charge your phone.
same here with my gionee E7 MINI..IT HEATS LOT
Mine also heats a lot.
Btw anyone tried rooting?. I m willing to root

My Galaxy S, takes far too long for charge completely ؟
Today was the battery level of 19%, Connect the device charger, and after 5 hours and her grandmother, reached 93%
also the phone became very hot
Yes, I am also wondering about that. It takes about 6 hours to get from 5% to 100%. It is fine for me, since I charge the battery in the night, but sometimes there are situations where you want to get your phone charged quickly.
My previous iPhone 3G took about 1,5-2 hrs for complete charging.
I can't offer any advice as to why, but my phone charges from 30% to full in about 2 hours if I use the mains charger, but takes about 3-4 hours if I plug it into the computer USB port. The other thing, my phone doesn't get hot, only slightly warm.
I thought the same when I first got the phone.Have owned an iPhone for the last 3 years and that chrged up pretty quickly using the USB charger, in fact the Wall Charger is still sealed,never used.
But using the wall charger with the SGS really makes a difference.I would say under two hours from empty to full.

the usb port on a computer can only deliver i think 0.25amps where as a typical wall charger can do 1-2amps which is alot more. There it always charges quicker with a wall-plug-charger.
Sorry, i am from denmark, therefore my native language is not english
mine charges from 10% to 100% in arround 3 hours using the original charger...
I had the same problem initially, just do a few full battery cycles (2-3) and it should go away. If not, it may be faulty - how's the battery life?

Are you using USB or AC charger?
AC Charger gives you shorter charging time because of the higher amp input.
my SGS takes around 2 hrs from less than 10% battery in balance to full charge via AC charger.
The stock wall plug charger rated only 700miliamp, if you need fast charging you need to get a charger rated min 1amp, I use my old n97 charger to charge sgs, take about 2hr fr.black out condition, the charger rated 1.2amp output

Ampere rating is a max spec, the phone will pull as much as it needs. So you gain nothing from using a higher rated charger.

The problem is there are still
Today i got this message
" bttray temperature too high or low "
When I do I charge the phone
Yes it will pull >1amp rather than .7amp

The S2 takes forever to charge the battery. Coming fron the iphone 4 i suspect this takes ay laeast twice as long to charge!
Considering the battery performance isnt that great, this is a double whammy!
What do you guus think?

Yeah, I noticed the same thing. I'm always charging it when I'm at home to keep it fully charged, in case I'm going out.
charging takes me about 3hours (from empty). It is stanrard time
Same here for charging. Between 3 & 4 hours. But battery life is getting better especially if i disable 3G and wifi

Im using nokia charger 1.2A and HTC charger 1A and also i have 0.7A all of them takes about 3 hours may be hardware bug?
I've been using a BB charger for it, and thought maybe that was the reason. Glad to know it isn't.

Yep, I confirm.
Charging takes around 3 hours.
I can use it almost 48 hours before it needs to be charged again. So it is not really annoying.
Stock SGS 2 with official battery charger and a full drained empty battery 3.5 hours to charge to 100% .

About 3 hours here which is fine, charging from the supplied charger connected to electricity mains. Are you charging via the USB connector? It will take a lot longer, something called trickle charge or something like that.

I noticed this when my brother bought the same phone. His takes a ridiculous amount of time to charge, maybe 1% per 10 mins or so and it gets really hot while doing so.
Mine on the other hand doesn't get hot at all and charges at least 3 times faster than his.
please state charge state, ages, fast normal etc.
firmware and revison thanx
The charger shipped with my S2 has only 700mA...
especially if you are using the phone (worst: gaming) while charging it seems to get never finished . I guess the current drain doesn't left much for the charging.
So i'm using my old HTC-chargers (one AC=>USB and AC=> MicroUSB) witch both supplies 1000mA.... ~43% more in theory
Hard to say how big the advantage is in fact, but it makes a difference.
Also keep in mind, that a standard USB-Port supplies max. 500mA, depending on other USB-devices even much less. I also read that the charging result is "better" if you not using it in the meantime.
You can buy USB-Chargers up to 2100mA (e.g Amazon), but i have doubts that this will be improve the charging time because on the type-label behind the battery is written Rated : 3,7V-1000mA. Even more current wouldn't not damage the device (afaik!!!), the device or the battery could not charge faster.
Maybe somebody knows about what is meant by the the 1000mA exactly. Would be nice if the device could be charge a little bit faster.
Otherwise i am going to buy a 2nd battery with an external charger.
greetings
I found this on Android Forum

USB charging is slow on the S2 as it uses trickle charging
"Trickle" is an exaggeration.
The phone can tell whether it's connected to USB or a mains charger. If the latter, it limits charge current to 650mA. If the former 400mA.
It will charge faster on the mains but not loads faster.

My other cell phones are fully charged in 2 hours, more or less. And yes, I'm considering selling it, because I like to use my gadgets and the SGSII doesn't admit an intensive use without running out of battery, unless you have a second battery.

Yeah, I do sleep more than 3.5 hours per day and I try to charge it every night, but the problem is when the phone runs out of battery in the middle of the day and you don't have 3.5 to spend in charging it fully.
I think the iphone 4 is only a 1420Mah battery if I remember correctly while ours is 1650. Sure, it takes perhaps another hour to charge but I don't find it a big deal. It does appear that the first 50% charges faster then the second half as well but that could just be my imagination.
I have read that Samsung phones charge slower so that the battery life will be longer than that of those other phones such as HTC where the phone charges a lot faster. I'd rather get another year out of my battery and it take longer but do admit 3.5 hours does seem like a while.
this topic has been covered. teh SGS2 battery driver is capped at 650 mA for wall charging, 450 mA for USB charging. this code resides in the battery driver.
someone could compile a new kernel with this value raised. other phones like the nexus one charge at 980 mA for wall charger, 480 for USB.
samsung capped charge current, likely for heat issues, nobody really knows.
same. take long time to charge and heating if charge n gaming. the hottest spot at camera side

In between 50%-100% screen was on for 10 mins with 8 mins whatsapp chatting and 2 mins whatsapp call..
95-100% took just over 20 mins..
Is this normal charging speeds for QC 3.0
Or I got a defective piece..

You're using the device while it is charging? That's going to cause some overheating and many other issues. Try charging it without using it and see if the results change.

That's how every li-ion battery charges. That's normal. This is precisely why manufacturers advertise 0-60% (or close) charge time instead of how long it takes a phone to fully charge
OP, give this a read - http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries .
tl;dr charge rate isn't linear.

I will try to not use phone and check the stats again
Thank you
All recent phones have a logic chip which decideds the rate of charage in order to minimize the effects of quick charging on battery life and to avoid overheating. Slowing down the rate of charging the closer to %100 is done in order to protect the longevity of battery life, the chemical process involved in charging is not %100 efficient and the higher the rate of charging close to capacity the less efficient it is, this translates to permanent loss of charging capacity next time you run the charging process. Temperature also affects the rate of charging the logic chip dictates. If its too cold it slows down the rate until it heats up to optimal range. If the battery didn't have a temp sensor you could make it loose %90 of its capacity simply putting it in the freezer then QC charging it. If its too hot there is a risk of overheating and fire, so if you are running resource intensive apps your rate of charge will drop to avoid excess overheating. There is NO danger in using the phone while it is charging, even resource intensive games
i heard the battery get totally broken after one year of using the original 25W charger , what is ur experiences ? does ur phone over heat too when charging does it get to 50-60 C degrees?
I've been charging mine with the turbo charger since day one, it's been fine. There is technology built in to monitor the battery temps and ramp down the charge speed as the battery gets full. I've had my phone for 16 months now.
Max temp I get is 42-44c

same here : 15 months with my MXF the 25w turbo2 charger.
Battery never go over 45° in charge, battery life still as good as the first day
In my car I have the Moto 25w charger. With navigation and other apps running the temperature rises to about 46 degrees. At this point the charge rate drops. Only if my telephone is at the cool air and out of its cover does the charging rate remain at the full turbo charge rate

Not so much that the battery fails. The connector (which is kind of crucial for QC 2.0/3.0) or the charge controller craps out. Battery's fine. Was fine when I did my swap out for charge failure. It's not the battery, which people incorrectly presume is the problem- the charge system is a feedback loop process running in the background while the OS is running. When you're dead, down, no charge in the battery, the device only draws USB 2.0 power levels, 500mA, until the OS can come up enough to manage the charging. Part of the reason they do this is because you're using a USB connection to charge with and unless you've got the 1.5 A USB charge slot or an AC charger with the ability to source up to 2.4 A of juice, trying to pull that much current will wipe your USB port on a PC/Laptop/etc OUT. This is just with traditional charging. Turbo/QuickCharge charging is about raising the voltages over the USB 2.0 lines on a cable to up to 12v as opposed to 5, to allow you to jam a bit more current through the lines and to the device, effectively doubling the power being fed to the charge system. Problem with that is that you REALLY need the OS up and running to manage that. It requires info from the Charge Controller chip that is handshook from the charger.
If your charge controller is damaged, or if the cable doesn't have clean data and power lines, it just simply WON'T WORK. It will just USB mode charge until you fix the "problem"- either of which requires Lenovo to re-work the board...if it's even possible to fix. USB charging takes forever with this class of device- because the battery is a huge tank of juice compared to the devices of old. So it "looks" like the battery got "broke".
Having said this, there's about 20-40% of the units out there, depending on the crowd you listen to, that have a defective charge controller system and the phone flat-out won't ever go into any mode other than USB.

First impression your charger isn't the right amperage. When I was using 2A charger wasn't getting a full charge , heated up and took a long time. Add a ROM, apps running in the background, charging mod and weak battery sounds like disaster. Looks like your phone reset also unless that was you. With the stock charger I'm getting at least 2700mA depending on how low the battery is. Could go as high as 3000mA in ampere.
