r2 optimal battery

I know this question surfaced in the past, but i cant seem to get more than 3hours of battery. Unless i turn off turbo/ OC in Bios, is this completely necessary to see 5+hrs out of this thing?

How do i disable flash from starting the 335? What other settings should i make sure to check when really trying to stretch its life?

 

That seems incredibly low. With turbo on and OC @ 166 mhz, I get no less than four hours of normal use. Generally, with moderate settings I get seven hours on average.

 

I only get around 1 hr 20 mins gaming time and 3 hrs to listen to my favourite musics x.x
Does turning off turboboost prolongs battery life a lot?

 

You may have a failing battery.. My r1 used to get 6 hours gaming, now I only get maybe 2 hours.... dell got me a new battery the other day though

 

Thats odd, according to the batterybar software, i have 0%battery wear. Generally, with overclock and turbo w/ battery set on "high performance" i get 3-4 hours. Which settings should i check into?

 

how about the discharge rate? what how much you get? mine is around 14000 when browsing using wifi and around 11-12000 when idle. and i got 4.6% wear on my battery, so around 3 hours usage

 

jrowinski, my r2 (i5 520um,8g ram) can withstand hours of daily use (wifi browsing, playing flash videos, typing, editing pdfs etc) with turboboost on, it's up to 6,5 hrs with turboboost off. But That's after I tweak power profiles and clean install without using dell datasafe, DWLAN, and aliensense.

you can remove your browser and media player from nvidia setting, also use integrated graphic card for general preference. it helps in my case.
I used to get 15-18,000W discharge prior to clean install and disabling aliensense, DWWLAN, and tweaking maximum processor frequency (on balanced: 70%, power saver: 50%), minimum frequency on 1%

that's all I do. for now.

clodderes, my discharge rate is around 12000 with wifi, browsing using chrome, and it's up to 14,000 something if I use USB dongle broadband modem. Idling is around 8,000-9,000, depending on which power profile i use. all with 3 bar brightness. my full charge capacity is 64,000 W, so it gives me roughly 5 to 6,5 hrs of typical usage.

I hope that helps. If any of you got other tips, I'm all ears..

 

6-7hrs sounds amazing. How much has the discharge rate improved after a clean install? How much more does the i5 get than the i7?

Here is a screenshot of the batterybar, i7, overclocked to 166, turbo enabled. wifi on and idling.

these are screenshots of my r2 idling and with light browsing. I was using usb dongle, wifi off (sorry but no wifi in my area so I'm stuck with usb dongle), balanced mode. btw, I'm using norton internet security 2011 which contribute to noticable amount of discharge. I can squeeze more battery life using MSE, but I have long history with norton so I stick with it hope that helps for comparing also include my spec (no OC, alienware fx on)

 

Hey im having similar problems myself. You should check out my thread incase there is any info useful to you, i will be sure to keep an eye on yours.

Thanks

 

Seems like im discharging too much juice, is it recommended i reformat to get rid of the bloatware or would it be something else?

 

Um, I only recommend clean install (reformat) only after you've tweaked your settings; I tweaked some setting (maximum/minimum processor frequency, disabling DWLAN service and aliensense, updating command center and intel graphics setting, disabling turboboost, bluetooth, LAN port, and firewire port from BIOS) then. At that time, I settled with 9-10k idle. Apparently it got lower discharge after I clean install and keeping the tweak I mentioned above.
