does this help the battery life in any way?
- Alex3917 10y agoNo, if anything the energy impact looks worse than before on OS X. I love Chrome, but the fact that it's almost completely unusable on laptops that aren't plugged in is problematic.
- stemcc 10y agoRAM is one of your least power hungry components compared to other parts of your computer, such as what generates heat (CPU/GPU) or produces physical motion (fans or spinning drives).
- Bud 10y agoThis makes no sense. RAM generates heat just as CPU does, and RAM also actually does consume a substantial percentage of laptop power. However, said usage isn't related to how much RAM is being used, really; it's a constant usage rate to keep the current RAM state alive.
- ptaipale 10y agoWell, it makes sense to me: CPU and GPU take in the order of 10 times as much power as RAM. RAM power usage just isn't depending on load, like that of CPU and graphics.
- cxseven 10y agoReducing RAM usage will reduce disk activity, though, so there's that.
- 0xffff2 10y agoWhy would that be? Unless you're frequently running out of RAM and swapping to disk, RAM usage shouldn't correlate to disk usage much, right?
- haneefmubarak 10y agoBecause all of that "unused" RAM in the background is actually being used by the OS for disk caching, thus reducing the overall frequency of reads.
- richdougherty 10y agoHard to know. Lower memory usage will generally help battery usage, but it sounds like the garbage collection is more aggressive now, which might offset the savings.
- greglindahl 10y agoIf you avoid swapping because of it, yes.
