Battery drain after SSD install on Samsung Laptop

[Lucabi]

Hi everybody!
A couple of years ago I bought a Samsung Laptop (model: NP300v5a) which had a good i7 processor and a 500 GB HD. I recently installed a Samsung PRO 840 (256 GB) SSD instead of the original hard disk and everything got better, with the exception that the laptop's battery life has really really shortened. Before installing the SSD it could last 3 or 4 hours, depending on Windows 7 power saving settings, and now it can't run for more than one hour and half, even if I use Samsung Magician (the software with comes with the Samsung PRO 840) or Windows 7 power saving settings to boost battery life.
Samsung's customer service doesn't give support on this kind of problems (I was told so by the phone girl who answered me).
Does anyone know what I should do? Thanks in advance!

That story, and the follow-up are 6 years old!

Do you have anything more recent?

well, you are right Yogi its rather old!i dont have anything newer but on some set ups with ssd i have noticed increased cpu and ram activity especially when performing writes of large files. also have you done any ssd tweaking like disabling prefetch, superfetch or something?

I have disabled Prefetch and Write Cache Buffer Flushing. Write Cache Buffer is enabled, however. I'm not sure about Superfetch setting. I've experimented with lots of different settings, just not lately.

yes i have done that too. also i have indexing dissabled , hibernation, windows restore and reduced page file memory to 400mb. i have done all that to free some gb from the OS ssd but also resulted in increased cpu and ram activity during copies mostly.

Lucabi, have you also tried any of these tweaks lately? also two years of usage maybe started to have an impact on batterys condition. it is possible that the deterioration of the battery emerged after the ssd upgrade.!

Likewise, I have disabled Hibernation, Indexing, Restore and I have my Pagefile set to 1024 MB.
