    I've managed to get it to run for about 6 hours plus on paperwork and web surfing with occasional video playback.

    That’s great you should share the setting to other Blade 15 base users. I’m assuming that you don’t install new ssd on free ssd slot, do you?

    Undervolting. I'm just playing around with because I'm not too good with all these technical terms. I used Intel XTU. Interface to me is easier to understand and it runs on startup, quite user-friendly.

    Core Voltage Offset -0.140V
    Processor Core IccMax 127.500A (default is 128, not sure if I should be messing with this).
    Turbo Boost Short Power Max 78W
    Turbo Boost Power Max 58W
    Turbo Boost Power Time Window 24s

    Cache Voltage Offset -0.140V
    Cache IccMax 127.500A (default is 128, not sure if I should be messing with this).

    Processor Graphics Ratio Limit 7x (for the work that I do, documents, watch videos, music production. No games. I don't think I'll be tapping a lot on the GPU.)
    Processor Graphics Voltage Offset -0.210V
    Processor Graphics IccMax 20A (can't rmb the default, should be 28A.)
    At this stage, I'm randomly setting numbers on the GPU because I have no idea if I'm really needing that power or not. So maybe someone can guide me on this.

    I'm not a tech guy, so I'll need help with the settings. These are the settings I used but please let me know if it'll do more harm instead or if there are better settings for undervolting, post it here too.

    I've done the CPU stress tests for 59mins (max duration for XTU) and the highest GHz is 4.0, average around 2.9 to even a 3.1. Temperatures max is about 80, the lowest is about 40. Used Cinebench and because I'm powering down on the CPU and GPU, the results are not that great (bottom 4). With the GPU at default and CPU at -0.120V, it's actually pretty good (top 4). But I'm not sure if Cinebench would be a good test for someone with my kind of usage since I don't use it to render graphics, but it surely is a good indicator for the CPU too.

    Total runtime is about 6 hours (not counting the sleep time, which in total is about 1 to 2 hours, didn't keep track).

    There are a couple more things I did which is not related to undervolting, such as dark mode, power saver, frame rate, screen brightness, removing/disabling unwanted/unused apps.

    Those are huge things to get better battery life. Keep that setting you’re doing already great with your base model with only 65Wh battery capacity.
    For answer your question about icc max, it is about power limit, how much Ampere your chip is allowed to pull the power @100% however I see rarely users tweaking this area especially on igpu since most manufacturers lock it down per bios, some are tweaking only on the core area (under voltage offset usually). To revert it to default you can try discard it or crashing the laptop (by put extreme low undervolte value on voltage offset, once it crashes xtu will revert the setting to default), FYI 8750H defaults is 32 A.

    I really wished the battery could have been slightly better. Even a 70Wh would've been nice. I don't use it for gaming, more for creative work and if it doesn't last long even during web surfing and documents, then creative works like music production (what i'll be using it for), will probably be worse.

    It’s the trade off for having extra ssd bay (Blade Pro 2019 has also lower battery capacity due extra cooling fans), however if you want to give a shoot, you can try buying 80 watt Blade 15 advanced battery like from eBay and install it yourself, I don’t see user doing this yet but theoretically like other notebooks with two different options (bigger battery or extra storage bay) you can install bigger battery if you want longer battery life. And I see it’s not impossible from this picture from Blade 15 2018 models.

    I bought the base model because of the extra 2.5" slot. Hopefully next time razer releases higher battery capacity where consumers can just purchase and replace it
