uniqe15 Posted June 21, 2015 Share Posted June 21, 2015 Hello everyone, is there any magic way to improve battery life on hackintosh? (e7440 on 10.10.3). On windows I'm getting about 6-7 hours of battery life on hackintosh its one and half. Is it possible to make a energy profile ? Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted June 21, 2015 Moderators Share Posted June 21, 2015 http://www.osxlatitude.com/tuning-performance-with-fakesmc-smbios-plist/ are you on Clover or Chameleon? Chameleon, you'll need AppleIntelCPUPowerManagement patched. Clover has it patched on the fly. Make sure you don't have NullCPUPowerManagerment installed.

uniqe15 Posted June 21, 2015 Author Share Posted June 21, 2015 I'm on clover, and i haven't got any nullcpupowermanagement kext Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 22, 2015 Administrators Share Posted June 22, 2015 There are examples of what to do here. This was all based on Chameleon installation, not Clover which may overwrite some of those settings... Link to comment Share on other sites More sharing options...
Karrerin Posted February 12, 2016 Share Posted February 12, 2016 Herve, have you managed battery life issue? Jake, how long your battery lasts in E7450? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 13, 2016 Administrators Share Posted February 13, 2016 I don't have battery life issue. My systems (including my Haswell-based E6440) are tuned and run on SSDs... This being said, I've never measured battery life on the E6440 between Win and OS X but I think they're roughly the same (around 4hrs). Win7 runs off a 2.5" SATA-III SSHD, OS X off a mSATA SSD in the combo slot. As a 1st element of comparison, here's a sample of what Win7 and El Capitan individually report : Slightly longer life in OS X is probably due to mSATA SSD vs. SSHD (with mechanical parts and motor) for Windows. I'm not disabling Turbo boost when running on battery. NB: Battery is Dell 97WHr, 9 cell, model CRT6P. No need for any AICPUPM patch on Haswell platforms. CPUPM is handled by the kernel for those, hence the need to patch it but AICPUPM can stay totally vanilla. Link to comment Share on other sites More sharing options...
