How to extend battery life for Samsung Ultrabook?

[LordLuBu]

Recently I had just gotten my Samsung ultrabook Chronos Series 7. I notice that I cannot remove my battery while charging like I did for most other laptops. It is somewhat like IPod and IPhone which the battery is in-built. I am very concerned about the battery life.(For my laptop, the battery usually lasts for 3 hours for high usage and 4~5hours for normal usage)

I usually have two ways when it comes to using the battery. I will like to seek your opinion on which one of them is better, or better yet, suggest another better solution for extending battery life(for long term usage, say 3 years maybe)

1. Activate Samsung Battery Life Extender, so that the battery will only be charged till 80%.(I heard that 20% should be left empty for lithium battery) And continue using my laptop as per normal while charging without removing the battery.(I cant remove it anyway)

2. I charge my battery till 90%, unplug the AC cable, and use the laptop without charging. I heard that it will reduce the amount of charging and discharging cycle on my battery, thus helping to extend battery life.(Correct me if I am wrong.)

Any input is welcomed and thanks in advance.

I'd want to save Samsung Recovery and a WIn7 backup image of the HD to wipe the HD and get a Clean Reinstall - Factory OEM Windows 7 for comparison, because I've not seen any OEM battery crapware that is better than Win7's built-in power options. The same can be said about all of the useless utilities the factory OEM's lard in along with the other bloatware that corrupts and throttles Win7. Most tech enthusiasts will not run these installs at all.

If you want to do literally a side by side comparison, then after saving your Recovery and backup, shrink C to do the Clean Reinstall to a new partition and try both as an experiment. Then you'll know for sure which runs better and can easily if you don't want it delete the Clean and Extend C again in Disk Mgmt, or we can help you delete the Samsung install and factory partitions and reclaim its space for the Clean Install.

I am still using Windows 7's power option to monitor my battery, with Samsung's utility extension Battery Life Extender. Sorry if I am a rookie, but I dont quite get the part for Clean Reinstall, do I have to go through those complicated steps to get a clear comparison? Because ultimately I just want to know which is the best way to use my battery to prevent shortening its life too quickly.
