Yes - that was kind of obvious. I think the question was WHY you do not want to "charge the battery when p3600 is connected with pc".
If you have a reason that others have not thought of, others might decide to do the same. Seeing as the USB is the only way to charge the phone - I'm guessing the only way to do this is modify the cable you use to connect to your PC. But then you'd NEVER be able to charge using this keyboard.

Lithium ion batteries do NOT! have memory so you
should use the batt up before charging them once more
it's a myth
it was Ni-MH batteries which was supped to suffered from that
heard that one can even damage Lithium ion batts by using that old myth as a way to "exercise" them
guess old myths die hard
same thing with the "you have to wait ½hour after you eat to go swimming or you get cramps and drown" thats a myth too
same thing with looking too much at the tv damage your eyesight or reading in with too little light on

Hi,on Prophet to disable usb charge,you can modify this key : HKLM\drivers\builtin\usbfndrv and put 0 to disable.On trinity,this key doesn't exist on wm6,verify if ,your os is wm5,thatv the key exists.

its good to wait half hour b4 any phisical exercise because the blood is naturally redirected to your stomach after esting to help digesting, exercising screws that up...
Watching TV is harmful in many ways, eyesight, radiation, hormones, day/night cycle, Can even trigger epilepsy...Especially using old TV sets.
Reading in poor light conditions can damage your eyesight if you do it often enough, it is possible to overwork any organ... Plus you get related problems like bad posture and back problems from subconscious compensating...

sorry for my english. i hope you understand me ok
I agree with Lithium ion batteries do NOT have memory...
... but i'd like to avoid charging battery when i connect Trinity to Pc because ALL batteries have a limited number of charge cycles.
continously charging make battery cells at the top lost a lot of charge cycles while the bottom cells no.
When battery cells finish the number of life-cycles, they are no more usefull decreasing the total capacity of battery.

Your USB cable isn't braided with 24-strand Unicorn hair. Therefore the power coming from the charger isn't pure enough for our Galaxy Nexus.

Stupid as it sounds, there is some truth to it (though OP probably didn't know, lol). Quick chargers wear out the battery a bit faster than a slow charger, so charging from the usb port on your computer is slightly better for the battery, but the charge takes a lot longer. This does not affect your battery capacity per charge, but affects how many cycles the battery lasts before it wears out.

Lithium ion batteries actually like a slow charge and discharge rate . By that I mean to prolong the cells life and IRS storage capacity. Optimum rates vary a little but I found in testing that makita lithium batteries provided best service with .5C charge and discharge rates...
Not exactly the same as your phone battery, but the same chemical make-up inside the cells..
Anyway.. lol

I heard that if you use a potato to charge your phone it doubles the battery capacity.

that seems about right to me. I browse a lot and routinely get about 3.5 hours screen time before my phone goes to the red zone. Which IIRC is around 15%?
I have my browser open and the brightness to 40% and my bluetooth off.
The battery life has been the sole black spot in owning this phone so far. I am sure the owners of the next generation phones will make all of us jealous. I bought a spare -regular- battery for just this reason.

[Q] Does it harm the battery if i do this?

I always had this question in my head and i think its time to ask. All android phones i had does this and i wanna know if this does harm in somehow the battery.
When i plug the phone to the PC to transfer some files it recharges the battery too, sometimes depending how big are they, the phone stays connected for longer. I want to know if it harms the battery doing this small, medium charges while transfering files.

Doesn't harm the new batteries.

More specifically, lithium-ion batteries don't develop the 'charge memory' older battery technologies like NiCad do if not allowed to fully run down before a charge.

Older batteries suffered from "memory effect", meaning that if you charged them before they were empty and until they were any less than full, soon enough their capacity would deteriorate.
New batteries don't have that problem. You can charge them any time you want for as long as you want. In fact, it's advisable to not let them discharge completely and charge them often.

It seems a bit ironic, previously we had to be aware from charging at any time and it was stronly recommended to charge only when battery is completely dead.
While these days it's better if we not let the battery completely discharged

[Q] Battery - should I charge straight away, or let it run down first?

I'm not up-to-date on battery etiquette, so thought I would check with you chaps. I should be picking my One X up from Carphone Warehouse tomorrow or Wed, but wanted to know whether it was considered better to charge immediately, or to use the battery until the phone dies, then charge fully, or some other third option. Want to make sure I get the best out of the battery, obviously.
Thanks!

What you really want to do is condition your battery. You don't need to do it immediately but in the first week or so of having the phone. By conditioning, I mean... Charging it until it's full, then using it until its fully discharged, then charging it again. Repeat this cycle ("fully discharged when charging") for 3 to 4 times... after that, you'll notice that your battery lasts longer than usual. It's what I've done with all my phones, seemed to work pretty good.

A lot of the time android will shut down just before your battery is 100% empty, you will find if you try to turn your phone on after its shut down it will still boot and run for 15 - 30 mins, depending on battery age and condition ofcorse. And if you keep on turning on the phone when its battery is very low/empty you will then start to damage it.

How to Prime Batteries
...Rechargeable batteries may not deliver their full rated capacity when new and will require formatting. While this applies to most battery systems, manufacturers of lithium-ion batteries disagree. They say that Li-ion is ready at birth and does not need priming. Although this may be true, users have reported some capacity gains by cycling these batteries after long storage....

Conditioning the battery was needed with old style batteries.. new Li-xxx batteries don't need one.. and what does an extra 30mins actually mean to you ...
now you can buy original replacement batteries for 20-30$, so if it loses it's capacity after some time you can easily buy new one...

I'd use the battery as soon as you get it until completely drained.
Then perform a full battery charge without use, its best to do this to ensure a full 0%-100% charge.

Battery issue

Dunno how to say it in English but physically my battery is getting bigger, and when on battery low, it gives me the notification and the phone just turns of on the same second.
The battery is starting to be like a balloon and and hardly fits in the phone, can anyone tell me what's happening?
btw, I'm using the stock ROM now.

Hi, found this on eHow and as automobile electrician dealing sometimes also with batteries i cannot confirm that your battery was bloated just because of playing games an charge phone at same time. Li-Ion cells don't like to be fully discharged. When u charge them before they go out of power is the best you can do to preserve their capacity.
Don't use your phone with silicon case when gaming because it can prevent air ventilation in the phone and cause it to heat up more when placed under heavy load like when playing games.
And now what can contibute to a battery bloatup:
Battery Components
• Most cell phone batteries contain a lithium-ion mixture. Lithium is an alkaline metal, and its ion simply has more electrons than protons. The battery also contains a positive and negative electrode, and when you use the battery, the lithium ions move from one to the other, creating an electric charge. Under normal circumstances, the lithium ions can continue to absorb and dissipate energy. However, if you expose the battery to certain conditions, its chemistry can change, causing undesirable effects.
Water Damage
• Your cell phone battery is extremely sensitive to water. The plastic casing provides some protection; however, if you expose the metal electrodes to water, they can corrode and become ineffective. Water leaking into the batteries case can cause it to appear bloated. Discard such a battery immediately because the lithium solvent can be harmful if you come into contact with it. If the phone has been submerged in water, this is usually enough to cause water damage to the battery if there is not a tight seal between the battery and the phone.
Heat Damage
• The lithium solvent that carries the charge from electrode to electrode is extremely sensitive to heat. If you expose the phone to temperatures that considerably exceed 77 degrees Fahrenheit, the battery may lose its ability to hold a charge over time. This is considered normal. However, if you consistently expose it to higher temperatures, then you can cause the lithium-ion mixture to rupture the cell, which can cause the battery to appear bloated. Most lithium-ion batteries contain fail-safes that prevent them from operating in extreme temperatures, but there is no guarantee that these will work in every case.
Prevention
• Prevent damage of this sort from occurring by not exposing your phone to extreme temperatures and unsafe environments. For example, do not bring your mobile phone near pools or inside of saunas. On hot summer days, keep the phone and other electronics out of direct sunlight.

But I can confirm this. I´m having actually here 4 batteries for the SGW and one of them is bloated due to heavy usage while charging the battery. This battery was my best battery but now it´s just a paperweight. It´s still working well though it´s bloated, but I´m not going to risk anything.
You can´t simply compare a car with its lead battery to this device, because in the car the battery is just needed to start the car. Once the engine is running the battery is not needed as the generator is producing enough electricity for the entire car and to charge the not needed battery.
You can even remove the lead battery completely and just connect the car to a powerfull enough source to get it started. Onec its running, you can remove the source too and it will continue to run.
With the SGW and its LI-Ion battery things are a bit different. You for example can´t simply plug in the charger and turn the device on without the battery. The battery is still neeeded to power on the device for two reasons. First is the charger might be not strong enough to offer enough power but the obvious one is, the circuit inside the phone reduces the charging current to a max. level and the voltage to be 4.2V max. It acts like a constant current and constant voltage source where the preset max limits can´t be exeeded. The real charging current and voltage are depending to the charging level and the battery resistance, but will never exeed the max limits in a proper working circuit.
Additionally this circuit is feeding the battery directly, so the current is floating first into the battery and then the battery is feeding the entire device. So at heavy usage the power offered by the circuit will be not enough to be simply passed to the device and so the battery will be stressed twice, as it´s charging and discharging at the same time.
This is still a simplyfied explanation to what is really going on, but explains a little bit why you can´t compare a car with it´s battery to this device.
Also, the batteries for the SGW do not offer it´s own protection circuit. The only circuit that protects the battery is build in into the phone.
So the best advice that can be given here is to avoid heavy usage while the battery is being charged. Better charge it first, use it then and recharge when not in use.

I´m not sure where you digged this out, but this is simply not the full truth. In neutral stage each element is having as much electrons as much protons it has. Ions are either having temporaly more or less electrons. They can be ionized positive or negative.
In a normal Li-Ion battery it´s the anode that consists of lithium and is having positive lithium ions, so less electrons than protons.
In a lead battery both, the anode and the cathode consist of lead. One is positive ionized and the other one negative.

Sorry if it souded as i would compare a Li-Ion to a lead battery. I was actually not doing that. By that i meant that i understand somewhat of batteries. I've learned about batteries (how different types work) back in school. All Li-Ion based batteries have their own protecting circuit. It is not depending on the phone. This circuit built in every Li-Ion based battery prevents it from beeing overcharged, wich would result in the battery exploding. It also gives the phone a limited feedback on battery charge status, and perhaps somewhat potecting the battery to be fully drained wich would result in irreversible damage to the cells. I agree with you that it is better to charge when not using them, but in real life this is not easy to do when you (by what cause ever) want or have to use your device. I am not a gamer so i am not using my phone that way.
Since i am using my phone lots of times plugged on a charger, making phonecalls and doing other stuff like email, surfing the web, watching videos and so on, and never get close to that issue (battery is almost 2 years old) i still don't think that that would be the biggest problem.
On hot days is it not recommended to use our devices with heavy loads, ofcourse you could climb into the fridge (may not be a problem then), and it is also advised to avoid humidity. That's all i know for now, that it would contribute to a bloated battery.
Sorry if i unattendedly caused some confusion.

Not all Li-Ion batteries have their own protection ciurcuit. Only the protected ones. Do a search on google about protected and not protected Li-Ion batteries.
In cellphones most batteries are not protected ones because of the circuit taking to much space and so incrasing the battery size a lot. Therefore the protection circuit gets moved into the phone but the battery itself is not protected at all. In most batteries the feedback you will only get is the temperature. It´s mostly a simple thermistor either being somwhere close to the battery or inside the battery. The rest is calculated by knowing the capacity and monitoring the voltage and current drain.
So the only circuit you will find in not protected batteries is the one for reading the thermistor, if there is one build in. But this circuit will not protect the battery against a short circuit.
Just to not confuse about this. There are of course protected batteries for cellphones as long the circuit can fit into the part where the connections are.
But the truth is this circuit can fail to disconnect the battery from a short circuit and there are even batteries with fake protection. So there is a pcb with a circuit, but this is just fake and doing nothing.
However regarding this discussion about bloated batteries it doesn´t matter the battery has a protection circuit or not. The protection circuit only disconnects the battery if a short circuit occurs or the battery voltage drops below 3V.

Buy a new battery.
