    Most Important: Do not use the phone when it is charging. That's damn harmful.

    Li-Ion Battery get hot while charging or while talking. When you do both at the same time, the battery get's extremely hot and can explode (not everytime).

    • Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
    • Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
    • Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
    • Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
    • Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
    • If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

    u've completely messed it up pal! the memory effect is seen in NiCd batteries. NiMH batteries do suffer from memory effect to some extent. Li based batteries (ion/polymer) haf little or no memory effect. so if the battery is li-ion/polymer then do not let it drain completely! one more word of caution: do not overcharge!

    I charge my cell as soon as it displays 'Battery Low' for the first time and charge it till it displays 'Battery Full'. I do not charge it when its half empty and always charge it till it gets fully charged. I also do not continue charging it after it displays Battery Full. I never put the charger on overnight. An important thing is to never remove the charger first from the phone and then from the power outlet. Always remove it first from the power outlet and then from the phone. Doing this the other way can damage the battery as well as the charger.

    ^^ This from Digit Fast Track to Mobile Telephony (page 77).
    "While charging the device, do not pull the adaptor cord out from the device until the main electricity supply is switched off, as doing this could cause a spike that could damage the device"

    @pathiks and mav3. Yes might have done that a 1000 times but 1 overheat is enough to blow it. Ask any mobile phone manufacturer or any electronics guy who is well aware of how Li-ion batteries work.

    Hmm me too pulls the plug off the mobile :D, however I had a bad exp with my 6600. I used to charge it every morning. So what happened over a period of time was that it used to discharge and get charged only the first specific amt. So if someday if I forget to charge it, it wud switch off automatically when that specific amount of charge was discharged. This happened around 2 months ago. Since then I'm not charging my phone unless it shows less charge. Now its working fine. But was scared as hell that I messed up the battery coz a new one costs 1200 :(
