بله درسته. برعکس اونی که معمولا همه می گن هست. من اون سایتی که پیشتر دیده بودم رو پیدا نکردم بنابراین یه سرچ کردم منبع زیر رو یپدا کردم که توی بخش ۳ در این مورد گفته. نوشته که عمر یه باتری بر اساس سیکل های شترژ هست که بین یه شارژ کامل و یه دیس شارژ کامل محاسبه می شه.
3. Memory effect? In a word,
Nope. The phrase belongs to nickel-cadmium (NiCad or Ni-Cd) batteries. If you charge a Ni-Cd battery before it’s completely discharged, it will lose capacity to charge fully the next time… as if it remembers the smaller charge capacity and regards it as the new norm. Hence, Ni-Cd batteries have to be completely discharged before charging again, to retain their full lifetime between charges. This is a peculiarity of Ni-Cd batteries, not shared by Li-ions. In fact, your lithium-ion battery likes it better if you
don’t discharge it all the way between charges. This is why Apple recommends that you go ahead and plug in your charger when the device gives you its low battery alert. When you charge, the battery doesn’t really mind if you don’t top it off. Li-ion battery lifetime is all about
charging cycles. One charging cycle is the time between one full charge and one full discharge. You can partially charge or discharge your battery many times during a single charging cycle. In short, your lithium battery has
no memory effect, and you can recharge it, in whole or in part, whenever you feel like it.
این که بذارید خالی بشه و بعد شارژ کنید عمرش رو کاهش می ده. ولی همه بخصوص فروشنده ها این طور توصیه می کنن که در اصل مربوط به باتریهای قدیمی Ni-Cd هست و برای باتریهای لیتیوم بده.
