Great laptop but why did they shrink the battery when 4k and quad-core need more power?

You know, with the previous laptop to this, the Yoga 910, Lenovo released a BIOS update where the 2 fans no longer can crank up to 100% when needed. Reverting back to the old '23' BIOS from newer BIOS versions solved that issue. Also with the 910, cyclical heavy throttling was a big big issue under 100% load. I saw that mentioned in this 920 review as well.

Should have tested the fan speed in the review I think but don't blame u for not knowing they may limit the RPMs for noise sakes (who the heck want that, yay throttling but it's quiet!!). I will stay away from the 920.

I am trying to decide between the Lenovo Yoga 920 and the HP Spectre x360 based on battery life. However, I want to compare the 4k version of the Yoga 920 to the 4k version of the Spectre 13.

I want the 4k version because I want 16gb of ram and a 1tb hard drive and only the 4k version offers these specs

However only the 1080p version of the Yoga 920 is reviewed here. This is rated as having a higher battery life than the 4k version of the Spectre:

1080p Yoga: 11h25m on wifi test, 2h20m in load
4k Spectre: 7h4m on wifi test, 2h1m in load

But I was wondering which one I should expect to be better if I go for the 4k version? Would the 4k Yoga's battery life be a lot lower than the 4k Spectre x360? If they are similar then I'll choose the Yoga as it appears to come out faster

Thank you!

Lenovo laptops are not the same old IBM workhorses. Quality is exceedingly low, and service not up to the mark.
For my business use, I purchased a high end Lenovo Yoga 900 (in the $1400 range) which immediately after it's 1 yr warranty was over, refused to power up or charge.
The Lenovo service center is charging me $80 just to figure out the problem, and has suggested a possible $400 for eventual repair.

No other brand I've purchased has given such a terrible experience - Dell, HP, Sony, Toshiba, Apple.
Why would someone buy a $1500 Lenovo when even the cheapest $300 HP machine doesn't go bust after a year?

Lenovo refused to repair it or even tell me what is wrong - free of charge.

Charging a certain fee for analysing the issue outside the warranty period is the norm. You'll get exactly the same with Apple, HP, Dell and all other major brands.

With respect to your Lenovo failing after a year, I would call that just bad luck. I bought a $1500 HP laptop for my son. It died right after booting up. Again, bad luck.

I've had an Acer Aspire S7-393 myself which worked flawlessly for the last 3 years. Does that make it any better? No. Just good luck  :)

If you want almost same as IBM quality then get Thinkpad series, not some fancy pants like yoga lineups. That is what they acquired from IBM and they are business laptop so that's why it's more durable than usual.
Other laptop is just pretty much lottery, it may break anytime depending on how much daily abuse.

Hi,
Does anyone knows about the UHD variant - which display panel is using .. cannot find any reviews.
Thanks

Can you please review the updated Lenovo Ideapad 720s 14" with 8th gen and MX150? Thanks.

@PG: Not at all.

@Malcolm: UHD mostly enhances text and vector graphics sharpness. Image and video quality enhancements on a small 14" display when viewing 4K content wouldn't be perceptible even when you're staring an inch from the display. Therefore assuming numbers like brightness, contrast and color accuracy are equal, going with the FHD screen will not take away from drawing experience.

Also, there are minimal battery life differences between same laptops with Intel i3, i5 and i7 U-series CPUs because faster chips take less time to boost and reach a ceiling frequency before dropping back to its base clock, consuming similar amount of power as a slower chip. Though this isn't the case for 35+ W TDP HQ/K-series chips.

Is there much real world difference between the i5 and i7 models, outside of gaming? I would be using this for office work and occasional Lightroom and Photoshop use.

Is there a difference in drawing resolution between the FHD and 4K UHD screens?

I'm tempted to go with the i5 FHD model for the increased battery life, but might "upgrade" if the drawing experience was enhanced with the UHD screen.

Thanx!

I am a new owner of the Yoga 920. I have been disappointed with the color of my FHD display. Is the ICM file you link AUO_B139HAN03_0 the X-Rite calibrated ICC?

Appreciate your time.

Jeff

Hi Jeff,

Sorry for not answering sooner....
The answer is yes - we always attach the calibrated ICC for each notebook we review.

Thanks,

Bernie

Why HWinfo detects only 4 cores??? It should be 8 cores - 4 phisical and 4 virtual.

Maintenance manual for yoga 920, page 43, confirms that SSD can be upgraded. But it is located on the other side of the mainboard. You need to unplug battery, speakers, side IO board, wifi antennas and maybe some other cables in order to remove the board.
