These are the some simple and affordable things which can be done to save your laptop & its battery life.
Cooling System:
The first thing is to check the cooling system of yourmachine i.e as laptops are completely packed devices the heat is dissipated less when compared to desktops.So it is essential to setup a cooler for your machine to extend processors life.If this system is not checked especially for continuously running machine this would lead to system breakdown(extreme conditions).The speed of the processor also gets degraded due to excess heat.
Charging Procedures:
Do not plug your machine continuously for charging.You may think that your machine will the fully loaded with power when you plug it continuously ,but actually what happens is thebattery gets heated up.When you continue this process,it leads to improper lifetime of battery i.e you machine will indicate full battery charge,but when you let it run for few minutes it drains up.So it is safe to charge only till the battery gets full and not more than that.
Softwares Needed To Be Installed:
Check that your system does not have unwanted software's.Install only oneAnti-virus program which is up to date.Check that you don't install two versions of a software.If you are going to use software's such as MAYA (Graphics) you need to buy a laptop with higher end configuration.See that you don't run two large software's in a machine at a once,this may lead to system stuck,this is due to insufficientRAM memory.Never hesitate to update your system,better switch on automatic updates.
