Your lowest discharge rate?

Hey guys, just wondering, perhaps you also have done a lot of tweaks to your laptop to make the discharge rate as low as possible?

I have done some tweakings such as undervolting my laptop, turning off the unnecessary background services (such as ntune, rivatuner, etc), and of course, reducing LCD brightness to the minimum. Afterward, my discharge rate decreased into 16750 mW (previously it's <20000 mW), I got additional battery life from 2:15 to 3:15, pretty nice huh? My battery is Li-on with 52370 mWH fully charged capacity.

I undervolt my t5250 processor, all the voltage consumption now is 0.95v on all multipliers (it's the lowest on my rmclock setting)

I wonder if you have other tips to discharge the battery consumption? what is your lowest discharge rate?

 

Here is one thread that discusses trying to reduce the power drain. It includes my basic suggestions such as Flashblock for Firefox. Turn off wireless if you don't need it and look at the Power Management options for the devices in Device Manager.

Some notebooks are better designed than others to be power efficient: See the attached screenshot for my Sony G11 drawing just under 6W. However, with a normal CPU and a dedicated GPU then 17W may be close to the limit.

ZOMG, 10 hours battery life! I wonder if I could go lower beyond this...

 

Most unlikely: the U1500 CPU is the equivalent of a 500cc engine is a motor car: It won't go very fast but will run all day on a gallon of fuel. Sony also made some other power saving tricks such as the integrated optical drive is on a USB channel so the power can be turned off. 12.1" display with LED backlight also helps.

The Samsung Q45 (normal CPU and X3100) can be squeezed down to 10W (see link in my previous post) but has the benefit of a 12.1" display (for a given brightness, backlight power will increase with display area, which is approximately the square of the diagonal).

I would see 15W as your bottom limit. My Zepto 6024W with T7300 and X3100 integrated graphics + 14.1" display can get down to 12W on minimum brightness. A dedicated GPU will always leak more power than integrated graphics.

see how f***** up my laptop's battery is lol. It dies in 40mins, but it will stay at 100% for 30 mins.

 

My system is a DTR so battery discharge is pretty rapid.
Best I`ve got with max brightness is about 2.3 hours.
