Afte debloating windows some more, and switching of memory integrity - plus using EPP 220 (with the old tiger lake that was too slow) - I'm now around 6.2% battery use per hour with 55% display brightness which is equivalent to 85% on my old Gram (though likely when it was new more 70% - IPS get darker over years of usage) - and around 4.5% at night with 15% display brightness. 16-18 hours of real world use time. Yeah Panther lake likely can still do it quite a bit better - as it can get much more work done at very low power states. The only slow down with pretty tough restrictions is app launch. Launching a bigger program takes 2-3 seconds longer - however sustained demanding tasks are just as fast as without power restrictions - it just takes some time for the CPU to ramp up. The advantage is even surfing the web, editing texts, C10 package states of 60-70%. Meaning 60-70% of the CPU cores are fully switched off. The key was making the ramp up slow - otherwise Windows very often spikes up power. Panther lake seems to be great with higher EPP values in still just sipping power. So instead of 1-1.5w power usage for the package with those light tasks, it can do them with 0.5-1w for package. Meaning with panter lake you don't even need to debloat that much - just set high EPP and get great battery runtimes. Getting runtimes longer will after panter lake mainly be possible by better displays - and that's getting tough with the 2026 generation OLEDs already very power efficient and during daytime easily beating IPS. I also got rid of most LG tools. I think it's better to use intel for driver updates, and so far LG hasn't pushed a bios. So I disabled the LG services and run them only on demand, only intel update manager and windows update manager are allowed to run. And fan setting I just do via throttlestop/windows power plan. Yeah no AI fan mode, but the old ones all available and it just is more efficient. I have basically any hidden setting on the power plans enabled via registry - which helped a bit too. Oh and the battery now has 81wh capacity - that's 4wh more than claimed. But we all know the 80wh to 77wh was just a change as often LG batteries didn't reach full capacity. Seems to be a bit luck of draw.

I guess prices will be around 1900-2500€ for the Gram Pro. AMD version maybe starting at 1700€. https://www.notebookcheck.com/Hands-On-Samsung-Galaxy-Book6-Serie-Alle-Modelle-Preise-und-Starttermin.1219629.0.html In Korea the Galaxy Book 6 Pro is slightly more expensive That's less of a change than expected. But this time I guess there won't be any prices below RRP for quite a while. Last year list price was more an indicative thing and there were a lot of discounts. Good thing about the Galaxy book 6 Pro is - they will only launch a single basic panther lake CPU model. All others go H or X. The basic one is really a strong pass, besides better battery life you gain nothing over Lunar Lake and actually have even worse graphics. 100€ more for an H is a bargain considering the difference (and I'm sure if you set a high Speedshift EPP value the H will not consume any more power)

It's now not only RAM, NVME and even HDD drives are basically sold out until 2028. Mainboard manufacturers cannot get materials and so on. Even if they lower their profit margin prices will go up a lot. It's only about how much they preorderd with old pricing. AI datacenters just take whatever is available. AI is now surpassing humans in basically everything - so it makes sense from a business standpoint that all available ressources should be used to scale AI. Now humans will not stop eating and using up resources but things will get hairy (and that's right in the point of time where many resources get much harder to extract and less available). Getting a new laptop right now surely makes sense just as anything else you really need for work or life. I still think Panther lake is the biggest upgrade in the Gram line since at least the 11. gen. It's the first time without a big compromise either in performance or battery use. With the limited cooling power - it will be the most performant, and with the battery life it's just better than anything before. Plus OLED really improved in text readability and power use the last years. Besides contrast there is no improvement in IPS displays since many years. Higher refresh rates are pretty old - LG just took a long time to use more than 60hz.

Yeah, the main problem is that it must be quite a simple setting because on my first try I got it right. I gues I can only CMOS reset the bios to start from scratch - I think the load default is a saved set of options, that doesn't include all options. I don't think you can really destroy something - modern bios will restore to default after a couple of failed boots. Looking for what enables Prochot to 98° I destroyed my completely unlocked power envelope. And yeah the price increase mentioned in Korea was my reason to buy the Gram now - I really wanted it to be below 1000€ before VAT - so I can detax it in the same year. I would prefer 32GB but I rarely need it - and I have a server with 128GB for really big workloads that is idle 5.5 days of the week. The 2TB models sometimes have PCIE5 NVME disks - meaning twice the speed of PCIE4. But yeah that too is a lottery. It doesn't look likely prices will go back within the next 2 years - except if we have financial crash and then it's really hard to predict with prices of anything. After switching to Bitdefender instead of PandaDome and disabling most things in it - especially the web protection - I get pretty reliable 15-16 hours battery life for working with 60-30% display brightness depending on time of the day. I'm pretty sure with Panther lake 20 hours would be realistc after debloating Windows 11, and making sure antivirus is not set to monitor whatever. I can myself identify scam websites, and click on manual scan if I get download something where I'm not 100% sure. Bitdefender looks like right now the lowest ressource free antivirus. Trying to fully disable antivirus doesn't work well anymore with windows 11. Any kind of update will then put windows defender instead of none. That's especially annoying on a server where you are super careful anyhow and firewall plus login security is way more important than antivirus. I guess the new 2025 Ultra 5H or X7 model will be at least at 2000€ plus VAT when it becomes available in April? I'm in Taiwan next moth but prices there aren't much better than Europe. Only China and Korea are cheap.

Well seing that the price difference between Panther lake ultra 5 H and AMD isn't that big I would rather recommend that model. That effectively OLED now wins over the IPS in battery life and the green seams for text should be mostly solved in newest generations is in my eyes the differentiator. I would stay away from the non H series basic panther lake however.. they actually shouldn't have better battery life Vs the X/H as panther lake can basically switch off all cores that are not in use and just run the 4 LP cores, and performance of AMD will be much better at lower prices. Well let's see once they are actually sold. LG will increase prices again for all 2026 notebooks in March. Best time to buy a panther lake or AMD gram were those group buying events in January in Korea. Also I think it's still a lottery it you get an IPS black or traditional panel. At least 2025 contrast figures on tests varied wildly.

quite a good comparison between AMD, Intel Gram Pro vs Samsung Galaxy Book 6 with Intel X7 Also a few more videos. Panther lake really buries AMD now on battery life, but also vs Lunar lake it's 20% better in real life. Quite impressive. Also OLED is by now better at battery life at higher brightness. LCD can onyl win at low brightness levels (below 200, above OLED wins easily). OLEDs really have improved a lot over the years while LCD haven't that much (and I'm quite sure LG Gram Pro uses IPS Black v2 panels, they just didn't talk much about it). With the OLED on the Gram Pro being anti reflective now too, I think the case for LCD isn't that big anymore. Too bad there is no microLED LCD by LG. There's talk about prices of the new notebooks rising again in March, that's after they already increased them in February.

Oh I finally found the Prochot Offset setting in the bios - it's under thermal management and then called TCC Offset. Just set it to 2 instead of 8. I don't see a reason to limit to 92°. Theoretically 0° is possible, but my old gram sometimes BSOD with 0 as it can overshoot by 1-2 degrees. So 2° offset is optimal. Edit it's a mess. I'm not sure anymore which setting I have to activate to be able to modify it inside the bios. I cannot figure it out anymore and it's locked now. However I managed to change some setting so I can change it from Throttlestop and it works, however also don't know what I changed for that - and in the same process I messed up some limits so that EDP other throttling kicks in at way lower wattage. It's a bit trial and error - if it doesn't work then full reset the bios and try again from scratch. But basically anything is possible that the hardware supports (no undervolting as Intel blocked this many yeats ago)... Edit: it's a mess. I simply don't find out what I did initially to have unlimited power. And bios load default is not fully resetting all of the hidden options, seems they are not part of the default. the best I get is 30w constant and before a 28seconds 45w window. So 10700 on Cinebench R23 is max. I had gotten 12.000 at some point with 40w constant power and that was with 8° Prochot Offset. Now I somehow managed to keep the 2° offset set via Throttlestop - but I don't get full power anymore... Limit window in Throttlestop doesn't show anything - it simply doesn't draw more.

Ah and what to buy. In general I would have said, wait and get the Ryzen 7 AI 450. They are sold cheaper than the poor Ultra 5 325/335 models right now with twice the multicore performance, and still great battery life (yeah those low power panther lakes gonna be astonishing in battery life still beating Lunar Lake by 20% or so but at actually less performance). The new H (or X) panther lake look great in benchmarks, but they will cost a fortune. Now the problem is - with RAM/SSD prices skyrocketing right now - prices gonna increase a lot more than expected. A lunar lake Gram Pro on offer or a 255H model on offer looks like the best choice. Especially if you want 32GB it's gonna be a steep price. LG sells the new gram Pro with 256GB SSD in the base models to counter prices (and likely betting buyers just swap with an older NVME they still own and put the cheapest junk in just for selling and getting the price right). Oh yeah - Geekbench 6 with AI fan mode: 2700/10600 vs in silent mode: 2700/10100 Geekbench 6 GPU gives identical 30500 approx (255h would have 15.000 multicore and 40.000 GPU score on default settings with LG gram more or less). So it hardly makes a change but Geekbench has not much sustained load. PL1/Pl2 set at 45w, and Speedshift EPP to 20 (setting it to 0 may gain some more points - but is really pointless as it increases heat a lot. On battery I run EPP at 180 usually, or 210 if I have scarce access to power.)

Oh I see, yeah the LG tools mess around quite a bit in lower settings. But it does make sense in a way. I locked everything in Throttlestop unter TPL to avoid LG messing around the values.

Any software licences do not get transferred, also all websites the login cookie is deactivated. Authenticator needs to be re-initiated. But all my registry hacks and modifications survice - it would take me ages to redo all of this which is needed to tame Windows 11. So it's still much faster. And a used windows pro license is like 10€ so I don't care and just buy a new used one. I don't really know how to deactivat a license so I can reuse it on another PC. Also I think not all licenses support this. Noise is very low. Actually I ran Passmark full test on Silent with fans off, and I still got 19,500 CPU mark result - so higher than an non modified. It fluctuates quite badly but 15-25w are possible passively cooled without the fans running at all. I really didn't expect the fans kinda mainly keep the base cooler but have not that much effect on the CPU below 5-10 minutes. See the results once silent once with AI fan mode. They are better than 155H intel inside the Gram. Passmark is pretty good estimate of real use except gaming. But it's quite obvious that the lower benches which are done later suffered from the heat build up (full run takes nearly 10 minutes) Cinebench is also with AI fan mode.

I asked LG Korea via email about Aerominum and it's use in 2025 LG grams. They replied that indeed they used it but exclusively in LG gram 16 pro models in metal grey colour. It wasn't used in white nor black colour models, nor in any 17". Also they said they still adapted thickness and frame of display for 2026. So I guess the rtx 5050 arrow lake models do not use it because they have black colour. Also it's not yet used on lower body also in 2026 but may come for 2027. I had gotten curious because my gram pro 16 with lunar lake feels cold like aluminium on the display but usual warm on the rest of the frame. So if it feels cold it's the new Aerominum. That's also why the white LG gram pro was 1196 grams but the metal grey 1226g with identical internals. So if they go all body Aerominum it would add well over 100g, I guess the backplate will be kept in magnesium, but the keyboard frame could switch for 2027. That way may only add 40g or so. The backplate is paper thin I don't think they will change it.

Why is the dynamic power limit so low? With that amount of power it will not even best a lunar lake at 40w with much more cores. Is it one fan only? Even then I think you could increase it by 50%. I think it's only needed to set overclocking lock to no then afterwards it's unlocked in throttlestop. With two fans could outright double PL1.

Lunar Lake, I'm a bit less positive about my gram. After activation of all power saving options it limits all cores to 37w and puts 28w max power use. That stays even if you plug back in. Now for battery use that strategy really makes sense, anything above 3700w brings rather marginal gains at a high power envelope. But if plugged in I like my 37-45w power budget which is about the max the two fans can cool. Panther lake will be much better. First 25% more airflow from fans , second twice the die size so that alone should bring 50% more power budget at same cooling. So panther lake you should be able to run around 60-70w continuously without worries after repasting and modifying the pl1/2 limits. Arrow lake similar. But it makes sense dual fan increases the cooling power around 50%. So from 28w to 41-42 average. 28w was around the max possible with single fan on U intel chips after repasting (before 23-24w). Note repasting once a year is likely needed.... The plate leads to quite big punch out of paste. And yeah still 8° Prochot offset, cannot find out which setting in bios locks this. That's about 7% less power draw due to this. But then maybe it means less problems with cooling paste punch out.

After repasting I now get constant fully loaded power use slightly above 40watts. Huge change. LG had put enourmous amount of paste onto the CPU. Now good point about that way is - it will never pump out as much as they put, bad think is performance. I went with Durnaut by Thermal Grizzly as this is considered to be the most durable paste on the market right now (except some funky Chinese ones where however you never know if you get what you order...) with great performance. Actually repasted my 2021 lg Gram - it was basically plain metal - everything of the Arctic MX5 pumped out. I guess that's quite common on grams with the thin case and thereby varying pressure on the heatpipe all the time. Not sure about My Gram - it somehow messed around so much that it blocked CPU to 28w and 37 multiplier - changes PL1/2 time limits and much more - it really goes deep down. Also it messed around in some hidden by default windows energy plan settings. Now it does some magic - but it's really changing things you wouldn't expect.

Usually I don't believe much in whatever apps supplied by vendors making claims about battery life improvement - but what does My Gram do? On idle it decreases the CPU package from 0.5-0.8 to 0.3-0.7 watts - that's really crazy low. I left my 2025 16 Gram Pro in idle with browser open and display off prevented for 2 hours and it only dropped 6.1 % battery - screen brightness at 30% which should be around 150 nits. That would be well over 30 hours of battery life. Surfing the web and browsing I usually got without gram about 6-7% per hour, but with my gram only 5% per hour - meaning around 20 hours batttery duration in real life. Yeah not panther lake levels but not far off. Wifi/Bluetooth both on. System drive Lexar NM790 - the lowest power use NVME with Devsleep (lowest) enabled. I really do wonder what windows settings does My gram change.
