What's the normal temp during charging? I notice when on charging mode,I can really feel the heat on the phone. Initially I thought it was cpu until I use an app to verify. Its showing 47celcius. Should I ask for a replacement?

47 is very high i guess , normal is between 36-42 celcius. Check if many apps are running in the background while charging . Download cpu spy in the market to check if the cpu goes in deep sleep or not.
mine the temperature goes up only in one case
when I am surfing the net while the device is charging
while only charging the temperature is OK. Also if I am surfing and not charging it is OK
I also don't think that 47 has any threat on the device
Mine idle's around 22°C, hits 29°-31°C when charging on a 1A (1000mA) charger, and during usage hits 29°-33°C during high usage with occasional, brief peaks as high as 40°C. If your charger puts out more current, I could see the battery getting hotter, but 47°C seems too hot to me. I'd look into getting it exchanged, unless you have something running full blast while charging on a 2A charger. How's your battery life?
my battery life is ok..deep sleep working well at high percentage...i left wifi own downloading some data for games, not sure if that will make the battery warm up?

Strange Issue!!
when my phone is low on battery and i try to charge it (with the original ac charger or the usb); sometimes (almost half the times) the phone instead of charging .... DISCHARGES!!
i have tried all possible fixes. tried the battery calibration apps also. but it gets ok for a day and then back.
i can only charge my phone while its switched off!
Details:
1. on stock TW4
2. 3 pages on home
3. total widgets= 6 ( advanced task killer; digital clock; 2- circle launcher; quick battery; weather)
4. i kill all tasks always before charging!
WHAT AM I DOING WRONG? BTW I HAVE TRIED TO REMOVE ALL WIDGETS AND CHARGE ALSO! NO LUCK!
HELP!!
It sound like you might have a faulty charger, have you tried charging from your notebook, it`s a bit slower at 400mah compared to 650mah for the mains charger.

Yes, as a matter of fact, right now i am trying to charge through USB with the same drainage.
Switch the phone off for a while!... let the sucker charge.
And the problem is not always!
this is normal, already been posted. the charger is limited to 650 mA on wall power, and 450 mA on USB power. so it is easily possible to pull more power than is going into the device, say if you are gaming or pushing the device hard with navigation or similar.
next time this happens, turn off the screen for 10 minutes as a test, then come back, and see if the charge increased at all. it likely will increase.

yup! i was having the same problem and did this Roger says and its exactly that... GL
if your phone is hot too it will not charge as well.

My problem is when I'm not using the phone at all and the screen is off. Tried charging through both wall and usb charger.
The only way right now I can charge my phone is while switched off.
I always kill all apps before charging also... Still!
And if its charging while on, screen off, it gets hot also.

Edit: i also have read in many places that using task killer actually cause more harm than good bcoz it disturbs the proper sequece of how android shuts down an app or process..and cleans up the memory..this will result some of the apps or process to stay awake or come awake again when it sould be sleeping...

I once had this problem..after charging for 6 hours battery was only at 60% and phone was hot..found out that although the screen was off..the phone was wide awake all the time. For me the issue was the wifi manager was somehow awake and consuming power..hence phone was hot and battery drain while charging. Check your battery usage graph and see if your phone is awake when it should not be..and pin down the rouge app or process..
Hope this helps..

I've got a similar problem, while charging in a car using the SGS2 for navigation. BTW, what is the maximum Amper I can charge the phone without damaging it?
I really dont understand why Samsung keeps supplying this crappy charger. Desire Z and iPhone 4 both came with 1000mAh ones. Super fast charge on both! Come on sammy... This isnt a 900mAh feature phone. This is a big battery hogger dual core with a large battery inside!

I am using HTC's 1000mA charger and still,this happens to some extent,only much less.Try overclocking the hell out of it and then start benchmarking.Charging?Hell no.You may even need to draw power from the house next to yours!

I read somewhre in this forum that samsung has set a limit of max amperage on this device to below 700 miliamp( cant remember the exact value for ac charging and usb charging) so thts why the charger is rated to 700mah

That's right,but if the charger was 1000mA like HTC's it would continue to draw those 700mA it needs even while in use.You wouldn't notice any difference at all with it charging while not being used,but when screen is on there is a difference.
They limited charge current to 650 mA in the driver code, so that's why they use a 0.7 A charger. Using a higher output won't help unless someone compiles a new kernel.
I charge the phone until 100%. When unplug, it immediately drops to 85%-90%. On one occassions, it dropped to 40%! What's wrong with it?

Thanks. But...i tried charging it whilst it was turned off. The icon showed 100%. I then unplug and switched it on. The same happened. So, it should not be Apps related. Right?

I suggest you do a simple trouble shooting...charge your phone to 100% while it is off.
Than unplug, switch on your phone and just leave it for half hour or an hour without doing anything.
Than swith your display on...and go to settings
Select about phone..
Go to battery use and tap on the graph.
It will show you a few horizontal lines.
Make sure your screen on and awake time bars coincide nicely.
While your screen is off your awake bar should be very very minumum... most of the high battery drain casses will have a very short screen on bar but a solid long line of awake time.
This is normally due to some rougue app or process...and you have to narrow it down.
If your graph looks normal..than you could be having a defective battery or in worst case a defective hardware.

The max of 0.7 amps is a partykiller... When in my car, I'd like to have my phone record everything (dailyroads voyager as dashcam), while navigating... Definitely discharging there while on stock carcharger! So I will have to choose when I'm going on holiday (12 hours drive...)

I had a same problem before. But after I reflash 2-3 times (literom 1.5 for now) it's gone, and charging normal on car and wall charger while gaming or navigate.
So I was wondering if anybody knows what the normal battery voltage is supposed to be for this phone?
Because I have noticed that the battery voltage is spiking fairly often at 4.3V or more, when it's charging at 90% charged or above.
current
Which kernel are you using? There is a option to change charging current in some kernels.. check for it using EXtweaks. if so change it to a lower value.. default is 650mA on my s2.

On mine too! I've seen it at 4.3v+ when the battery is at 100% charge
I'm no theoretical electrical philosopher type, but voltage will read higher while you're charging. Your car battery is at ~12V while the car is off (it's a 12V battery), but while the car is running voltage will be ~14V

Which battery app is that?
Yea it only seems to spike above this when charging above 90% before 90% it never reaches 4.3V. I've set an alarm to tell me when it goes above 4.3V that's how I know.

Are people here with this problem also experiencing the problem of the phone detecting that it's on low power USB charge mode when it's actually plugged into the wall and supposed to be on AC??
Not me, but we don't know that this is a problem.

I was charging the G2 in the car today while using gps navigation. The phone kept loosing percentages even though I use a fast charger. Looking at the GSAM stats, it seems that the phone did not draw current from the charger at all... Could it be because 35 degrees Celsius is too hot for the battery and hence the the phone prevent charging?

Yes, it's a safety feature.
It was drawing roughly 40mA. What this person said. ^ It also slows on top end charge.
as the title says, my G2 is charging at barely 500mA. while earlier it used to do at 1600mA. Now the charging speed is painfully slow.
Using stock charger and cable, just like before.
D80220b-HKG. Total Stock. Unrooted.
any solution?

really helpful forum.
anyway i found the cause. Gsam helped a lot.
It's because of hot weather these days.
Normally battery temperature is between 30-35 °C. When i plug in to charge, it starts fine at 1600mA, but battery temperature also begins to rise and as soon as battery hits 36°C, thermal throttle kicks in and charging rate drops to 500mA to keep the temperature down.
In winter didn't have this throttling.
Also if the phone is turned off then it doesn't care about temperature and charge at full speed all the way. But when it is ON, it intelligently negotiates charging rate depending on thermal conditions.

i think this thermal throttle came in after recent D80220b update.
really annoying though. i have lost quick recharge capability.
any way to bypass it? 500mA is way to slow

So no solution guys?
If i turn it off and then plug in the charger, it charges fast like before (1% in 1 minute).
But when turned ON, it negotiate really slow charging rate and phone feels just cold from back side. When it used to charge fast, then little heat could be felt on back cover.
Right now if i want to Keep it ON and charge at full rate, i have to keep battery temperature under 35°C which can only be done if i keep it in front of AC or in refrigerator.
Gsam is just guessing the rate based o charge before and charge after.
When it is charging slow go to settings and batter and check what it's detected as charging with will say AC or USB.

Turn off thermal throttling in the 'hidden menu'.
There is also a throttle for when the phone gets too cold, FYI.

Install gsam battery monitor to check temps during charge. Mines goes to 40 celcius with fast charging .i disabled fast charging and my battery goes to 37c and slowly decreases as it reaches 100%. My suggestion is disable fast charge to increase battery life. Its only like 15 to 20 minutes difference to me.

Even with regular use mine goes upto 40 degrees and with certain apps and heavier use mine goes upto 60 degrees celsius. It gets warm i the top right corner of the phone . Is thid normal ??
Not normal .

I don't think 60 degrees is normal. I think phone manual says it should say below 40. Try disabling fast charging and see what happens.
Hi ,
Can you install cpu-z and check your temperatures.. i just want to have an idea of another phones temperature handling
If your using fast charge it will heat up a bit. My hits 45 celius while using it. With normal charging it stays at about 30 Celsius.

My heatup issue is with charging port side. It heats up a lot while charging. So hot that you can't touch it...
If i disable fast charging, my charging speed becomes extremely slow.,
I also seem to get better battery life when I have fast charge off, only use fast charge when I'm out and about to top it off.

Mine is only 20-30 minutes difference between normal/fast charge. Max charging temps for non fastcharge = 37c ( depending on what hour i charge, at night is 35c.) .Fastcharge = around 40c-42c max(for now)
How slow is extremely slow?
