Hi All,
How much does your battery last ?
Mi M17xR2 is 2 months old and battery last only 1 hour (trottlestop enabled with 12x multiplier and powersave option enabled), according to HWinfo the Wear Level is 10.4%
is this normal ?

I got 17% wear even though I barely use it in battery mode.
I thought to take off the battery when not in use, but my laptop really looks weird.
Right now it gives me around 1 hr 10 min under 9400 GPU, LCD mid lit and other normal. -
Yup that is very normal for both battery life and wear and tear %. Mine is roughly about the same on all my M17x's. I find that if I drain the battery all the way till it dies my wear % always increases slightly. Like 1% or around that each time. Over long term use though the battery will keep going down and end up not being able to hold its full 100% capacity charge.
I like to keep it in there as a UPS though + i move the notebook around quite a bit from time to time. So it is handy to have 1hr or so battery life.
Cheers.

Yeh the wear amount can go quite high after while even though you don't use it much. The battery in notebooks, for the most part need to be actually used. Even if they are not being used they will still slowly but surely wear down and die. So the best way to prolong them is to discharge them down to about 50% charge and then store it in a dark cool place.
However most of us like to keep the battery plugged in and use it as a UPS. So theres not too much we can do really. Just make sure to use it from time to time. Like once a week or so. + don't use the battery till it hits a very low% as that will wear and tear it more often than not. Once in a while it is good to completely drain the battery as well. Usually like once a month or once every 2 months depending on overall battery usage.
Cheers.

Yeh thats true actually. I found the same thing happens to me. So I try not to let the battery get too low or die anymore when I use it. Sometimes I forget of course. However you can also set it in the power options when you would like warnings and low battery signals. That will help to hopefully minimise the wear %.
Cheers.

Mine is 3 months old. HWInfo says it has a wear level of 6.5%. I currently get slightly over 2 hours in power saving mode (low brightness, Video cards set to maximize battery life, Processor under %50 of full speed).
I leave it in all the time except when I take the laptop apart. Only fully discharged 3 times.
I dont know what it means, but that is the way I roll

^^^^
nobody told me that when I was asking for info on discharge to prolonge my battery life and guess what I got....
7% more wear!

My M17x is about 6 months old, and when in a class without a plug to suck power from, I can get about 2.5 hours. That is not idle! Not that writing programs use a lot of power...
Batt- power options - onboard video, screen 50%, all other settings the same as when it is plugged in. -
2.5 hours? Hmm... I've tried many settings on mine and can't manage more than 1.5 hours from full charge. I have all lights off, stealth mode off (this feature really is useless btw), settings to battery saving mode, brightness to about 40% (it's very bright for my eye ahaha), etc. My average is a tad over an hour which means I don't go anywhere that doesn't have an outlet
-
well first Red has the R1 that has the integrated option, runs far less juice than the 4870CF
Make sure in your Power Save profile that the ATI Adapter is also set to Maximize battery life. Sometimes the Power Save mode forgets to set that.
And for the hard core, you can try to use something like RAEDON tools to down clock the cards, but I dont have first hand experience on this to help more than that. -
I wished that my battery would be supported by warranty...
-
The only thing left to do is turn down the clock on those video cards seeing as I don't use them anyhow But I'm always by an outlet so it's alright.
