Hi. I need more info. Too many factors here.
How old is your battery?
Do you use your laptop mostly on battery?
After boot, in activity monitor, is there any app or daemon running in the background pumping energy?
What are your bios power setting? battery profile? Mine is adaptive.
Was it always like that or suddenly your battery capacity drastically decreased?
If you have windows, is the battery life the same?
1) If you have windows installed on another partition (or disk) do this to check your actual battery capacity:
The issue I've been coming across recently seems to be mostly with Dell's XPS line of laptops, though it can certainly affect others: My new XPS 13 9370,www.ultrabookreview.com
If your capacity is above 90Wh, don't proceed to full discharge. just do a cmos reset (see below).
Do this once maximum and read carefully. Respect the 3 to 5 hours necessary to cool down the battery after full discharge.
2) Once done before switching on your laptop, disconnect the battery and do a cmos reset by holding power button 1 to 2 min to fully discharge the mobo capacitors.
3) Do a full test at idle disabling sleep and report the time until nearly full discharge.
4) remove ADP1 ssdt in patched folder. reboot. clean nvram at clover screen. reboot. put back ssdt. reboot. clean nvram, reboot, shut down. Reboot.
This improved my battery life. In my case it was a new battery that needed just to be calibrated.
5) If all of this fails. Try a clean install.
Coming back to this after loong time, so i tried voltageshift and used values of -135 -110 -135 and looks ok. So i installed coconut and see that my battery is:
Yes so by the looks of things my battery is crap. Well also note charging with 39w while on battery discharge would be around 37w (haha so same discharge time as charge time) but with voltageshift would be around 18-22w which is better actually felt that i would go around 5hrs defo more that 3hrs. Ok so with this state of my battery (it also tells me to replace soon) i guess it is the best i can get atm.
looks like my laptop is older than i thought..
i have 15" i7-7700q 4k 32gb 1tb
so what kind of voltageshift offset are you using for this proc? what would be the lower discharge wattage you could get? Also has anyone tried to use ./voltageshift power <PL1> <PL2> changing these values to limit power use to improve battery life? disabling turbo? thanks
