    Hey Guys,

    I was wondering if anyone knows what the battery life on the 2017 4K Razer Blade is. If anyone did a test please reply with your results, or if you know the answer please also reply with the results.

    I get 9+ hours on battery using word and One Note with wifi off and battery saver on, backlight on, and screen at 30%. On 2016 blade QHD+

    Don’t expecting 4K Blade 14 to run longer than 7 hours. Maybe with normal light usages like browsing, paperwork it would only 5 to 6 hours. If you want want longer battery life get FHD one. My FHD Kabylake 14 could only last around 8 hours on light tasks in battery safe mode.
    It’s pretty decent battery life for late 2016 14 QHD+, had this model for around a month before sold it for FHD, it just could hold not 6 hours for non gaming usage, did you make some tweaks like disabling touchscreen, disabling dGPU etc? It could compate my late 2016 Blade stealth battery with newer CPU architect (Kabylake) which is cool.

    9 Hours of gameplay and with the new Razer Power Bank you can expect to last up to 15 hours

    Yes right;) Don’t trust every advertisement on TV, it’s not good;) It’s only for stealth with USB C power supply, not for bigger brothers 14 and Pro. In fact in real usage Razer PB would only bump stealth late 2016 QHD maximal to around 14 from 9 hours. Maybe on new 8th gen CPU stealth it could reach 15 hours.

    Whoops I put an hour because my 2015 pro gets about an hour of good gameplay. Maybe 3 hours of regular use? It's a terrible battery on the 2015 pro but I guess I never intended to use it as such. It sounds like the newer ones have better batteries.

    No tweaks, only battery saver on and wifi off. And I can stand by my remark because I made it through 9h of lessons in uni with 20% still left.

    I see you have Blade early 2016 right, i thought late 2016, though it’s a decent battery life.

  10. Quick note on my Blade 14 4k - With tuning you can get excellent battery life.

    During normal work load for myself including Chrome web browsing, emails and Word document creation I am getting 9 hours on the 4K at 50% screen brightness. Temperatures are ranging between 39C and 42C.

    Below are some of the changes I made. Obviously, all of this is at your own risk. Be careful in the Services section. Take a quick Google if you do not know what the service does before disabling.


    · Uninstall Cortana

    · Disable Synapse - always re enable when gaming

    · Review Services for all internet connected apps (Razer and Intel). Razer has GameScanner, SDK something and Synapse (disable all). Intel has a number of "Connect" applications to disable.

    · Add Throttlestop - link to guide below

    · Undervolt GPU using MSI Afterburner - Keep this undervolt applied even when not gaming

    · Uninstall Killer Wireless Manager

    · Use balance mode in battery settings

    · Limit CPU to 99% in Advance Power Settings

    · Lower CPU maximum frequency to 2750

    · Disable Turbo in BIOS

    · Disable Screen Refresh – Intel Settings

    · Disable OneDrive

    - Stay on Windows 1703


    I am not 100% sure if all of the tweaks are resulting in the better battery life or just a combination thereof. My gut tells me it is the CPU/GPU undervolting and disabling services that are constantly pinging a external server looking for an update and or sending back diagnostic data.

    Cortana Uninstall Guide: Read carefully and read again. Uninstalling Cortana changes access to the Search bar. Other than the search bar being disabled I have not seen any other negative effect.

  11. I have a couple of questions:

    - intel settings state that disabling screen refresh will decrease battery life. Is this true?
    - I have read that people have had issues with connections after uninstalling Killer Wireless Manager. Have you noticed anything of this nature?

    Thanks
     
  12. I'm not certain about Intel screen refresh. Definitely no issue with uninstalling Killer. No speed differences or connection issues.

    The key is in the Services section and taking down Automatic server/web/update services running for non-windows apps. Plex, ITunes, Steam, Uplay, Origim etc all have services running that eat up the battery. Switch to disable or manual.
