Not an issue, a question : battery life #49

Hello sir,

First of all, thank you for posting your CLOVER configuration, I've been using it and I'm quite happy with it! I have the exact same config as you do. Just a quick question: roughly how long does your battery last? Mine seems to be not even 2 hours (even though I have a battery with only 130 cycles).

Thanks for your help

Hello,

Glad this github repository helped :)

iStat menus estimate 11 hour "idling", more about 9h not doing much - simple web-browsing. but my computer has the beefiest configuration possible : battery is a 61++ pack ( 4X50M08812 / 72Wh ) plus the internal one

I'd recall changing some stuff related to power management in "pmset":

actual settings:

$ pmset -g
System-wide power settings:
Currently in use:
 lidwake              1
 autopoweroff         1
 lowpowermode         0
 standbydelayhigh     86400
 autopoweroffdelay    28800
 proximitywake        0
 standby              1
 standbydelaylow      10800
 ttyskeepawake        1
 hibernatemode        0
 powernap             0
 gpuswitch            2
 hibernatefile        /dev/null
 highstandbythreshold 50
 displaysleep         15
 sleep                15

 halfdim              1

you can debug when the computer wake from sleep using pmset too:

$ pmset -g log | grep -i "Wake from"
2021-12-28 13:43:46 +0100 Wake                  Wake from Standby [CDNVA] : due to PWRB/UserActivity Assertion Using BATT (Charge:61%) 9677 secs

=> you should just have entries when you wake the computer from sleep (opening the lid or pressing keyboard)

-> not from an email polling / calendar or timemachine backup while the computer is left sleeping at night

Regards

Wow, thank you so much for such a detailed answer :)

I have the regular flat battery and I just installed istats. It indicates a 46% battery health with 85 cycles. That's different from what I read in the "about this mac" section where it says 136 cycles.

In fact, I was wondering how the hackintosh deals with there being 2 different accus in the laptop. I guess you can't really trust the "battery time left" value and all battery-related data displayed on top of the screen.

I will try to run some idle tests with just the internal battery and with the external battery to see how long the battery actually lasts.

Again, your repo helped me a lot and I'm very grateful for that. Thanks again.
