My battery depletes even during charging for example if i play game or use barnacle.I have tried 3-4 different ROMS and its still the same.ALso,it take a lot of time to charge 100 percent.What is the problem guys.

The radio in the x10 is the problem.
Ask SE to program better.

Do you charge the phone via USB (computer)?
This is a common issue if you use your conmputer as a USB charger. Computer USB can't supply enough energy to your phone. The USB current is too low only 0.3mA or 0.5mA.
Just use the ORIGINAL charger or other well-quality charger with higher current (700mA+). This is enough for both charging and playing. Of course the charging will take longer time while playing.
The higher current will not damage your phone. It will charge your phone faster.
NotOriginal and cheap charger may have low current-output or the charger is sometimes bad designed than the phone will recognize it as i computer USB. (if bad designed than the phone takes only low current even if the charger is able to supply more)

Sometimes the radio uses more juice than the poor original 700mA charger can supply.
Causing a lot of heat to build up on the battery.
No,i dont charge through usb guys

Not glad to hear that. I have never (only 2+months with X10) observed a problem with the original charger while using the phone (playing, GPS or wifi). Sometimes a bit warmer, which I consider to be common.
In general is the reason the same. The phone requests more then the charger supply
I think it's a software issue.
The bluetooth used to eat away at the battery but BB.67 sorted that out.
Wifi never was a problem for me.
But the GSM Radio is a absolute battery PIG.
It's using so much juice it's scary.
I hope SE sorts out all the ****.

Well it is probably also related to the signal level..? I use BB 58, never use BT. The GSM signal is almost full at home (while charge).
BTW: To charge the phone with the original charger takes tightly 1h for me. (from +/-30% to 100%) (not using the phone)
Mine's was not charging above 88%, but then I deleted batt. stat and it went to 98% and then 97% and then again to 100% then I used an app called Battery Calibrator and everything is fine now.
Depends what game your playing. Pocket legends with screen and volume on full, wifi connected, overclocked and set performance etc etc I can use a fully charged battery plugged in and drain it in 2hours. Its just supply and demand, the charger can't keep up.

Yeah.. it's not getting enough juice.
The GSM radio "heavy power eater" + wifi = no good.
I use battery doctor, which gives options to kill unwanted applications, monitor battery temperature, do full battery recharge cycles.
But also you need to turn off Wifi for battery save and keep u away from radiation

I checked again and I think its coming just from the battery.. those terminals. My battery never reached over 45 C and usually operates in 32-37 C and phone does not reboot at all by itself, may be I am just over cautious. Also, it is X10 HD (newer batch).
May be there is something wrong with the battery as I have flashed many roms in last few days and had deleted batt. stat everytime I flashed it. Enlighten me on this stuff. Should I undervolt and underclock CPU to avoid any damage to CPU?

Hi all,
It is really exciting to see how a new device's forum gets filled up so quickly . (i'll be getting my device sometime today so I feel like a small kid waiting to go to the candy store hehe)
I did do some reading on http://www.batteryuniversity.com/ and also in different parts of the forum.
But i am not sure how this case fits in all of the battery discussions out there. If am going to drive in the states for 3-5 hours a day where i;ll need to use my phone afterwards to continue my day.
Will keeping the phone plugged in the car charger hurt the battery?
Thanks all.
The best to do in order to increase your battery's life is to let it drop to 5 or 10% then plug it on your car charger.
It will last longer then if you keep it plugged on the charger, that's for sure.
On the other hand, the average life of a battery of this type is between 1 year and 1 year and a half.
Personally I keep a second battery with me all the time.
That's what I used to do with all my previous devices so I never be short of battery
Thanks, then i guess i'll play it safe and recharge when it goes low on juice.
If i dare ask, given the scenario where you disrubt the battery while charging, would it hurt it? I read that it is better to keep it charging once plugged in, but then again this is Li-Ion which should not get hurt if you take it out while charging!
Thanks
Not charging in the car
I noticed that when I have my device pluged into car charger and use it as GPS, it does not charge or loose power. In other words, if it is half-charged when I get into the car, and I drive for 2 hours, it is still half-charged, no more and no less.
What is going all?
Thanks

This is correct, but for the good of the battery you need to have it down to 5% (or less) from time to time

I used to have this behavior with my HTC Athena, but did not see it yet on the blackstone. I'll check in the coming days and will let you know
Hi Fadik,
I'd recommend just using your GPS and charging at the same time. Go with BigDede's advice and let it run down a bit before plugging in. This will help avoid possible overcharging.
Compare this with what most laptops are put through - permanently connected to the charger and hardly ever being used on battery. Our Dell still has more than half its capacity after three years of this. If you are still using your HD in 2 years, give a battery as a birthday present!
I don't know of anything that would damage your phone's battery during normal usage. The main battery killers are deep discharge (protection circuits turn your phone off before this point) and very high temperatures (you weren't going to leave your HD on the dashboard of the car during summer while you shop??). Oh, and the obvious, including blocking your car's wheels on a hill, providing canine nutrition, etc...
Hope this helps...
Thanks all for the feedback and input.
and I guess, I should replace the battery every year and a half

This is a common misinformation.
Do charge the battery often. The battery lasts longer with partial rather than full discharges.

Avoid full cycle because of wear. 80% depth-of-discharge recommended. Re- charge more often. Avoid full discharge. Low voltage may cut off safety circuit

All quotes from this handy table at batteryuniversity.com
So to adress the question of the OP:
Your battery will probably do just fine, as long as the pack itself does not heat up too much from the prolonged charges. The battery it self should be protected from overcharge, and tickle charge should not hurt it.

Im talking about personal experience here
I got my 2 batteries dead in less then 2 monthes on my HTC Athena
due to charging the device everyday while on 50% or more. (Actually charging it in the car, in the office at home, etc ...)
The 3rd one lasted more then a year when I was letting it drop to around 15 or 20%
Again, this is personal experience

I had this same thing when charging through the USB port in the car stereo. I had to revert to the dedicated car charger providing power from the cigarette lighter socket to get it to charge.
Hello
I had some trouble in the past, charging an Ipaq in my car.
You have to check how much the device can provide.
I think the wall charger is giving 1A.
On my USB car charger it could output 750mA. Maybe that's enough to maintain battery level in the case of the HD in GPS use.
I'll check.
You can check how much your usb on your car radio/USB can provide.
But I suppose it's 500mA which is the standard level given by a PC.And that may not be enough.
I just wonder is it possible to disable USb charging in Nexus One
until now i have fond nothing about this
i rely need this because i plug my phone for tethering at work
and the battery is 100% already there should be an option for this
Not sure why you need this, when the phone is 100% it will stop charging and draw power from USB while plugged in, surely this is preferable to rapidly draining the battery while being tethered?
the problem that i am using the phone for 8H for tethering (all the work time)
and the device get toooo hot i want to stop the chargeing ntile the phone battery dry than i will charge it again

From what I've seen from other threads on the subject of charging, doing what's practically a full drain and then charging again will not only create more heat but may also shorten the life of the Li-On battery.

It's not that making it 0% before charging it kills the battery life. The Lithium Ion battery's life cycle is poor and that's what it's infamous for. What makes it's life shorter is the amount of times you charge it. When you charge it all the time you're reducing the life of the battery greatly. This should help with that subject.
As far as disabling USB charging, I've never heard of it and I don't think it would be possible. If it is, that's great. My question is; why don't you use WIFI Tethering? You get the same results and you don't have to charge to use it.
If your phone gets hot while tethering, just use SetCPU to slow it down a bit... or maybe use a task killer to get rid of some of the background tasks. If your phone's already charged to 100% then it shouldn't get hot just from being plugged in.

SetCPU wont have any effect on this because the battery is what is getting hot from charging.
I still don't understand why people even use SetCPU anyways.
Couldn't you modify a USB cable and clip the power wires? I know it might be a hassle but it would be a sure fire way to keep it from charging and I believe the data connection would still work. That way you could have a true data only cable.

I've found that it almost doubles my battery lifetime by reducing the CPU speed when the phoneis on standby to almost minimum... Otherwise my phone doesnt last all day (from 8am to 1am)... It is actually one of the most useful apps on the nexus for me at the moment...

Most people misunderstand how a processor works. Your phone automatically idles at 386mhz. Setting a MAX does nothing but limit the availability. A 1ghz processor doesn't run at 1ghz consistently. A 1ghz processor just means that 1ghz is available. If your phone is sleeping then it's not using very much at all. The only reasonable change would be to change your MAX to something lower for Screen On or setting the MAX to like 100mhz for screen off. Other than that, you make no changes.

Yes, but not more often than that (I've heard numbers like every 50 cycles (~2 months)). Unlike other types of batteries, LiIon batteries do not like the full discharge / full recharge cycle.
Take the battery out. The phone will run off of USB power only. It works with my old G1. I haven't tried with my nexus though.
USB Connect without charging Galaxy S
I just tried 'snipping' the power wire (Red) on a USB cable, now nothing happens when connecting the cable, it's as if the devices (Samsung Galaxy S and Nokia E72) need the power line to connect for data transfer.

in fact that's not a good a thing to do, the worst ennemies for liion batteries are heat and voltage stress.
voltage stress results from either full charge or full discharge , the optimal charging pattern is 10% - 90% (but partial charges in between are of no harm at all)
by all means try to avoid full battery drain and/or keeping charger plugged after full charge.
following these guidelines you should more than double you battery life span
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...

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

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.

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??

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.

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?

As i posted before...something is always awake on your phone..try looking at your battery graph..and i am sure your device is quiet warm..

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.
Is it possible to ruin my phone's battery due to overcharging? I charge my phone overnight no matter what percentage it is on, I still charge it I know this is bad, but can this ruin the battery? thanks
You should be able to charge as long as you want w no problems as long as you're doing this in a cool or room-temp environment (rather than say leaving it alone in a car charging at high noon w AC off, windows down & no sun shades on the windshield). If you have your phone charging in hi-temp conditions too long\often your battery swells & you get gradual irreparable damage.

If u make a correct use of your battery it won't get damaged. Extreme overclock, overvolt, etc can ruin your battery, but if u charge it every day because ur battery is empty it's ok, and u won't have any problem.

You should be fine. Just look out for power surges!

thanks man =) thanks to the both of you who replied
Normally, when your phone reaches 100 % full battery level, it stops charging and starts discharging. At around 95 % level, it starts charging again. This all takes a toll on the battery, especially over a long period.
If your phone's battery is at or above 50%, leave it alone or turn it off for the night.
I have an external battery pack for use during the day time, just for situations like this.

I don't think that's correct. It should switch to a trickle charge, which won't harm the battery, not stop charging completely.

What I spend a lot of time charging the phone through USB? I leave it on charge at work plugged into the computer through USB as there are no free plug sockets. My battery just seems to be getting worse and worse over the last couple of months... Could this be the problem?

It'll automatically stop charging itself when it's full, it's impossible to overcharge a modern cell phone battery these days. They are a bit more computerized than the old nicad batteries from back in the day. It's actually healthier to give lithium batteries partial charges at a time instead of draining to zero percent and charging to 100 percent.

I doubt it. Could be a faulty battery, but more likely to be apps draining it in the background. Install BetterBatteryStats and see what is using the battery.

i'm using app called full battery & theft alarm. i always charge my phone during sleep, and this app will wake me up to disconnect the charger if the battery is full.
i hope this will prolong the battery life
How do you know your battery is getting worse if it's always charging?
My personal experience is the less you charge it, the better it will perform. However, when you DO charge it, make sure you are less than 30% battery and charge it to 100% before removing it.
For me it's easy, I basically charge my phone at night when I go to bed and that's it. I easily get through an entire day on this phone, though I admit I usually only have about 2-1/2 hours screen on time (I mostly use my tablet when I am at home)
