It really is very frustrating to have a weak battery that cannot hold much power to last a day with average activity. Reasons for a weak battery are the misuse of the battery and the lack of proper maintenance. The capacity of a mobile phone battery is measured by its standby time and talk time. It is measured in milli-amph hours (mAh). Rechargeable batteries have three main types, Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), and Lithium Ion (LiIon). Lithium Ion (LiIon) batteries are what you find in most mobile phones and in order to preserve the battery you might want to follow these steps.

Though there are Nickel-cadmium, Nickel metal hydride, etc, after the invention of Lithium-ion battery, because of its efficiency most of the laptop manufacturers are selling it along with their respective laptops.

Second, Remember not to play media devices like CD player when you are working with a battery. The point is the battery has to spin the CD. This will drain the Lithium mines Ontario battery power quite fast. So to stop the battery from draining fast by entertain yourself when there is power supply.
So how long does it last? Anything from 3 to 9 years if you search this question on Google. Everyone has a different opinion. In my experience about 6 years is the average. It's basically a large watch battery and is constantly supplying a trickle of power to the motherboard. Just like many of my watches the battery can last 2 years or up to 6 years (Fossil watches don't seem to last long for me for some reason). How long was the PC in the warehouse before it was delivered? And, how long was the motherboard in the warehouse before it was installed in the PC?
