I know its bad to overcharge your phone, so when i sleep i leave my phone plugged in and charges in about 2/2.5hrs and the rest of my 5hrs more sleep its overcharging. is there a way to slow down the charge which i can calibrate to about 5hrs and change it back for daytime charging. will be Very useful to me
using:
Ressurection remix pro ics v1.1 + siyahKernel 3.0rc2
Uh overcharge? Correct me if im wrong (someone who may be a little bit more informative), but our phones are made to prevent overcharge. Once it reaches its maximum, it actually starts discharging and then recharges once it drops to a certain point. There should be nothing wrong of leaving the phone plugged in when you sleep.
thats a + to hear =D i dont need to worry about it ty!
although i guess my older phones dont, running GB (galaxy ace, huawei u8220, huawei u8110)
s2 has overcharge protection ,so it should not be a problem
If you're still worried after Kaze's reply you could get yourself a timer plug from pretty much anywhere, cheap too. Set it for 3 hours and away you go.

I know there are a bazillion battery related threads for the X10 already. I have in fact read many of them. I cannnot say that I read all of them.
When I play Pocket Legends on my X10 (for a few hours), my battery will go low enough that the phone will shut off EVEN THOUGH the phone is plugged in to the wall charger while playing.
If anyone else here plays Pocket Legends, can you tell me if you are experiencing the same issue?
I have the default .5a charger that came with the phone... should I see if I could find a higher capacity charger? Would that help? Or would that just fry my battery?
The only thing I can think of is that there is not just built in function that says to stop charging when full, but also, don't charge when warm/hot.
Other than this irritant, I really like my X10.

I will test for you now. I play pocket legends too and i dont think i have encountered this problem but I am testing to make sure now.
EDIT: OK when connected to the pc to charge through usb, I dropped 5% from 58% to 53% battery after about 10 minutes of playing. This is on minimum brightness and about half volume.
I will test now with wallplug.
EDIT2: On second test using the wall plug, minimum brightness, half volume. I began at 54% and it dropped to 52% after 15 minutes exactly.
Maybe I have not done enough testing but its pretty conclusive that it fails to hold a charge let alone gain any during a play session of pocket legends. It seems we have a problem.
There is a "Battery saver" slider in the options. Maybe that will help? I might try.
EDIT3: Turns out battery saver just cuts framerate. The further along the bar the more the framerate gets cut which i suppose would technically help with battery but it leaves the game looking horribly choppy in motion.
I think the following would be a good scenario...
With your phone at less than a full charge (95%), plug the phone into the wall so that you know that the charge is on an up cycle. You do not want 100% charge when starting the test.
Start pocket legends and play for an hour or so (2 hours would be ideal). Note the battery level afterwards.
Thanks for Testing!!!!
I appreciate it.
BTW... I am BuLLitz in game as well.
i had the same thing happen to me playing angry birds. but it never dropped past 12 percent. started at 59 percent. played for about 1 1/2 hours. not sure if it would have went completely off but I've heard that you kind of have to break the battery in. I got my x10 on the 27th of December 2010. and i have been noticing longer batter life after each charge. (on charge 5 now)
Hey everyone,
Got my x10 second hand about 2 months ago and think the battery is pretty good, better than my old bb storm anyway! Havnt found the same problems with pocket legends and angry birds, and found the phone did not lose any charge when playing angry birds with max brightness, I cant vouch for it charging while doing this though. But I did notice my charger is a 700mA one as opposed to the 500mA mentioned by the thread starter. It may well be worth getting a higher spec charger as there is a BIG difference between .5A and .7A you could try a 1A charger but I havnt noticed any difference in charge speed when using a 1A HTC one. Another thing to try is conditioning your battery every month or two, let it run down until the phone dies and charge it switched off overnight, could be the placebo effect but it seems to help! Hope this helps.

Our phone won't charge if it reach certain temperature around 52 degree or 50 degree and more. So it's useless to charge while playing a game. Because it will stop charging when the temperature hot enough. And when we charge while playing, the phone temperature will increase faster. Btw I play pocket legends too but never play while charge. ^_^ play and just take a break when our phone run out of juice.

Thanks to everyone for their input (and 3Dawg for providing test results). From a full charge, while using a wall charger, at about 3 or 4 hours the device shuts down due to a completely drained battery.
It SUCKS.
It shouldn't be using any battery if it is on a charger...
That's my opinion anyway.
It makes sense to me what was stated by epinion as I suspected that the charging shuts off if the device starts getting hot.
But... I think I will look for a stronger charger anyway.
I don't know if it matters, but I probably should have posted my phone info:
X10a
Firmware 2.1-update 1
Baseband Ver. 2.0.46
Kernel 2.6.29
Build 2.0.A.0.504
Turning my brightness down as far as it gets helps improve battery life (while plugged in) but does not fix the issue.

This is clearly a problem with the charging circuit.. meaning you need to try send it back to SE..
This is why i hate SE.
As some of you may have read about charging issues and have rooted phones that seem to charge slow, then you probably have read the temp fix by restarting with you phone pluged in. This itvself does work if you have a newer fast charge capable kernel. Ie: pretty much any imoseyon kernel. This is true and effective till a call is placed, then the charge will go from hundreds of mA down to around 150mA. (Get battery monitor app/widget from market) to increase charging even faster, restart phone (not hot restart) being plugged in or not doesn't really matter. After phone is back up, you will notice its charging super SUPER QUICK! (Im using the latest imosey GB kernel btw) after phone is up and charging, don't make any calls. Text n surfing are fine. Put the phone in to hibernate mode. Sure you wont get any calls or texts for that time, but with the phone still actually on and the kernel working with even less to do because of its sleeping state, the charging should fly! Get the widget n try it out. I average about 1% every min to min and a half.
After you hit the 90% mark though the kernel may kick in and slow charging waaaay down to complete the charge. Feel free to thank if this helps ya out and good luck :0)

hi I've heard plenty of times that you should charge your phone once you get it or charge overnight..is this true in anyway? I always go straight to playing with my new phone and then charge once battery dies..any thoughts on this myth?
Hi. I have heard a few different things about this. I think there is a thread on here I read about it as well.
First is that it won't matter because batteries no longer need to have that memory thing.
Then there was one that said let it deplete, charge it and then when the light goes green unplug it and replug it in. The light will go red for a few more minutes and then green. That will set the battery.
Then I also read that you shouldn't charge it completely or let it completely deplete because that will lessen the charge over time
The last I heard is that (and this was under the discussion about extended batteries if I remember correctly) the batteries are made so that the battery meter tells us it is dead even though there is still a little bit of a charge on the battery that way it doesn't do anything bad to it.
So I really think it depends on who you listen to. I did the let it deplete and charge it thing once so far. I get decent battery life. I tested it and got 10 hours out of it with medium usage and I usually get more when I toggle off the 4g when not using it but haven't timed how long for that yet.
Hope that helps until someone who knows more specifics posts something.

I don't think it matters any more. I plugged mine in after I did initial setup and let it charge to green light, didn't do any special bump charging or charging while off. The battery is designed to be used as is, without any tricks. Always overcharging to 100% or completely draining to 0% is probably worse than just using it normally and plugging it in when you notice it's relatively low.
There's a battery log that Android keeps regarding voltage and reported capacity that it uses to adjust the percentage display that you see on your phone. This changes over time as it gets a better idea of how the battery discharges, so built into your phone is a mechanism to make sure the reported capacity is accurate. If it gets "off" a bit, like if you see a huge spike up or down in battery capacity after a reboot, it's just adjusting itself.
But, as you know, Android users love to control everything by themselves, and not leave anything to some process behind the scenes. Hence the clamor for root so we can install whatever we want. So some people like to trick this adjustment mechanism by force charging the phone to full when it's off, which gives the battery capacity adjustment mechanism a "true" full charge to base its reporting on. Also, I don't believe the kernels in stock ROMs will charge to what it believes a full 100% charge is, to protect the battery life. Bump charging kind of gets around that, if I understand the process correctly.
Also, I don't charge overnight (lack of outlets in bedroom) so I make sure it's topped off before I go to bed. Even if it's not, it can make it through the night just fine, since it's not being used. So that's not that much of an issue anyway.
TL; DR: Just use it, plug it in when you need to.
As the title would suggest, my poor GS2 gets VERY hot when charging. Not all the time, but often.
If I charge from my PC's USB, it doesn't, but when I use a mains charger, it overheats.
When I finish my night shifts, my battery could be down to 20%, so when I go to bed, I plug in the phone, set it's alarm and pop it under my pillow, like I have done with every phone I've ever owned without issue. I wake up during the night and pull out the phone to check the time and almost leap out of bed because of how hot the device has become.
To make matters worse, it's discharged in battery power. This morning was the final straw, as when I checked the phone and it was red hot, it was also dead. I held down the power button and booted up the phone. It showed 15% battery left. I know people say that when it's charged, remove it from the charger, but it isn't practical. Besides, I've never had to do this on any other phone I've owned. This is unacceptable for me to rely on any more. Is this a common issue?
Or my fault because I have rooted the phone the tried custom roms/kernels/modems on it before?

1) change to a diff kernel and see for the issue.
2) well charging from 10~20% to full 100% will lead to heat up the phone than charging from 50~60% to full 100% , hence also check for the same and see

I should have mentioned. This happens on any Rom and I've tried 4 kernels and still the same issue. Only thing I haven't tried, is going back to Samsung stock rom. Going to try that today, see if that solves it and report back.
Like Samsung told my wife "when it gets hot dial *#*#4636#*#* and note the battery temp".
Is it still under warranty

Well the PC's USB output would be limited to .5 A whereas your wall charger could provide 2 A. This might just be normal IMO, although I can't say that my phone gets ridiculously hot during charging. As others mentioned, I would check the battery temp.
The issue is already in his post and the solution as well.
1) The S2 has the tendacy to get hot. Its all very compact and there are no internal ventilators so the S2 dissipates heat to the rest of its body.
2) There is a Power difference between the charger and a USB cable. The charger gets hotter since it delivers power directly of a higher voltage and slightly higher amps then a usb port.
Your issue comes from one sole thing. Your bed. beds have very poor heat dissipating abilities, in fact, it has none. Considering no fresh air is delivered to your device, because it is stored under your pillow. Not to mention your pillow, the rest of your bed stop heat from leaving and it builds up. Ontop of that your heavy head is resting on it, pressing the pillow tight around the device.
in short, it has no way to relieve the heat. There is a simple solution of a non technical matter. Don't put the darn device under your pillow.
(the same counts to people that use there laptops on there beds pillow or covers without a proper cooling matt, before wondering why the hell there device shut down all of a sudden.)
The problem is you put your phone under your pillow. I made this mistake a few weeks ago and the phone was too hot but no problem when i charge it somewhere not under the pillow
I agree, I should stop doign that. But one question, if that's the case and the getting hot is normal, then why did the battery drop from 100% to 8% while plugged in?
Your cooking the battery, thats why.
i'll admit i charge my phone and leave it ON the bed so air still circulates but it did used to get hot. Not sure if any changes i've made such to things kernel, ROM, modem or undervolting has caused my change in temps but my phone never feels warm anytime day or night weather its on charge or not where as my partners phone (stock sgs2) does get hot using the same charging habits as myself

Another odd issue. If I mains charge my phone or connect it to my laptop(not PC the PC charging seems to not effect it) the phone lags. Menus take longer and it really struggles to register my touches on screen.

For the AC charger this problem is known: if the charger is of poor quality it will generate too much 'noise' (ripple) which disturbs the electric field used by the touchscreen. However the original Samsung charger is of good quality and does not have this problem.
Experiencing these kind of problems when charging by a laptop USB port however is abnormal.
Interesting.
I bought an official Samsung charger off ebay, and it produces the same results. Much to my frustration.
Leaving it plugged in all night however was fine, I placed it on a shelf and the phone was actually cold when I woke up. I'm just worried the battery is ruined. It seems to drain quite quick.

Another problem i faced recently was the battery draining to fast, i was told to pull the battery out for atleast 3 mins, this lets the CPU etc cool off, since then i've had no problems at all and getting a good 12 hrs atleast on battery use

Hey guys i am on CM10.1 with cm kernel... am really confused about charging my phone... i usually prefer to charge my phones over night ... is it okay.. ? i keep the phone on ac charger all night... and when i wake up its 100% charged..., the point is the device gets charged in 2-3 hours.. i usually sleep for 7-8 hours so the phone is lying around plugged into power for 4 hours.. is that okay? its holding to 100% for nearly 4 hours... that freaks me out... or is it trickle charging... i mean it drops and then charges back? i also read somewhere that the s3 has a built in mechanism to protect from over charging.. or it shuts down charging if the battery is heated up... since i am not on stock rom is that mechanism still in work ?.....
btw i really dont care about the battery life cycles if its goin to run decently for 2 years...
I always charge my phone overnight and never had any problems (Stock and Custom) You're safe
you're fine
Phew...needed someone to say that.. thanks..
