2019 X1 Yoga Gen 4 Poor Battery Life

2019-08-01, 15:08 PM

Anyone else experiencing poor/short battery life on their new X1 Yoga gen 4, (p/n 20QF0016US, i7-8665U, UHD) ?

Have been experiencing between 4 -6 hrs battery life with lenovo default factory settings and little to no work load.

I am experiencing the same, short battery life 4 - 6 hours (advertised 18hrs) on no use or light webbrowsing and email, and when plugged in fans are on all the time and computer overheats.

What is showing in Task Manager to be hitting the CPU when plugged in/fans on/overheating? Keep in mind that the fan inlet vent is on the bottom of the laptop, so more care is required to avoid restricting it.

 

Anyway, I don't see that behavior on my 8665U/4K UHD/16GB/1TB X1Y4. About the only time I ever even know the fans are running is when watching videos with higher than 1080 resolution. Did your laptop come with BIOS v1.13 or 1.14 and EC v1.05? Everything else up-to-date?

that is what I would expect. I keep it on flat table thus the air-flow should be good. Memory is runnging around 8Gb, 50%, processor bounces around 8 to 12%. 

 

I ran all the updates through vantage before doing anything else, the current BIOS is N2HET31W 1.14. The core teperatures are around 55C, with maximum record 100C. 

the fans are running in intelligent colling, balanced mode. Is there a way to check if the fans are actually operational?

My RAM is at about 50%, also, but my CPU idles at 1-2%. Try sorting the CPU column high to low and see what's using yours.

 

What are you using for temp monitoring/reporting? HWMonitor on mine is showing 40-41C right now, with 62-63C as maximum.

I will keep an eye on it. It was running at 60C maximum at 100C, and yes I am using HWMonitor. I ran a full hardware scan with Lenovo Vantage and no issues, and after that I am currently at 3-4% processor (likely not related), nothing sticks out, and heat has come down and temperatures are closer to yours, 50C, and laptop is not as hot anymore.

Thanks for the help Nate. Not sure what have changed tho, but things are looking normal now. and back to the original topic the battery life shows as 9hrs now, not 5 as before.

Hi, what program do you have open when it's idling 1-2% CPU usage? I am still idling at around 8%. 

 

I am at 60% battery and it's estimated 4 hours of battery left.

Thank Nate and everyone for your reply.

 

I did a system update which included the BIOS and Intel Management Engine to the latest firmware. This seems to have resolved reporting of poor (4 hours) batttery life issue. At this moment, I now see that vantage toolbar battery power reporting between 8-14 hrs. Will see how it performs for the next few days.

 

Thanks.

I just got mine today. i7 with the UHD. I think I've run all the updates (I used both Lenovo Vantage as well as running the Lenovo utility deal). When it was all done, I was still only showing an estimate of 2.5 hours at 50% charge. I'm definitely hoping for better. Maybe there needs to be some settling in time? I'll keep track over the next few days.

Good day and welcome to the community.

Battery runtime estimates are dependent on many variables.

What kinds of things are you doing with your machine... watching video (and at what resolution), coding, rendering video, etc? What level are you running screen brightness at?

Regards.

Thanks for responding. I had restarted the computer and had it running with nothing else happening for about 5 minutes. The only thing open was task manager because I wanted to see what kind of background tasks were running. I have the screen set at 50% brightness. As I said I’ll keep an eye on it the next couple days to see how it’s doong over time.

 

Since I have your attention and I know you’ve spent a good amount of time with this device, can I ask you a separate question about HDR? I went into windows display settings and clicked on the options to play games and apps in HDR. When I did that, the display got very dark with a very red tint. I tried to run a Dolby vision video in Netflix and it was impossibly dark. Have you experienced anything like that with yours? I can watch Dolby vision videos in Netflix with the HDR option turned off without any issues.

Same thing happened to me when I switched HDR on for the first time.  Then I experienced flickering between bright and dim display when I had apps open.  I read in another thread here that there is an Interl Graphics Control Panel and it was recommended to set the saturation setting down to -25.  So I did that and it seemed to resolve the issue.  Have you tried that?

I returned mine when I heard about the Comet Lake update coming later this month, as well as the Yoga C940 coming in October.

I was also considering the Dell XPS 7390, but I tried and returned that as I wasn't impressed. I'll make a decision between the refreshed X1 Yoga and the C940 after they are both out next month.

Is the Comet Lake update just a faster processor? I haven't read about it.

As I understand it, it's the latest Intel 14nm processors, which they are calling 10th gen, even though they differ from the Ice Lake 10nm 10th gen processors. I'm not sure how many machines are out with the Comet Lake processors so I haven't seen benchmarking that shows whether/how much faster they are than the 8th gen processors.

I was able to find some articles about the upcoming updates. Thanks for the info. Fortunately, I don't think I will even use this version to it's performance capacity, but the new C940 looks great.

 

I am still concerned about the HDR screen working properly though. How did you determine that yours was faulty? I've never had an HDR screen before. It is a bit tough to know if it is working properly or not. I've tried some 4k HDR videos on YouTube and don't seem to have any color problems. Were the problems found only when you used Netflix in Dolby vision? Is there a setting in Netflix to cater to Dolby vision?

I'm not a tech expert, so honestly I determined it was faulty just by looking at it. It looked terrible when switched into HDR mode. It was somewhat better after getting the Intel Graphics Panel updated and removing the red bias, but it still just looked extremely dark. By comparison, the XPS 13 7390 looked only slightly dimmer than it's usual display when you switched it over to HDR. Same for my Razer Blade 2019. The way the X1 looked, there was no way you'd ever want to leave it in HDR mode.

As for Netflix, I don't believe there is anyway to calibrate the Dolby Vision. It just comes on automatically. I thought Dolby Vision looked fine on the X1 Yoga after I got the red bias removed.

I also thought HDR youtube videos looked and played well when HDR mode was set to off in the display options.

Thanks for the info. The HDR setting seems to be working ok for me so far. It was just strange when it dimmed considerably when I first turned it on as you experienced on yours, but some saturation adjustments seem to have corrected mine. I'm going to toy around with it again tonight as I've only had it for less than a week.

I have had my computer for about a month now. But within the last week, something strange has started to happen. The battery gauge shows plenty of power, but then the computer suddenly closes down, and just prior to doing so, the battery gauge shows 0%. When opening the computer it will again show say 78% power, but then a few minutes later it will again close down. This even happens with the charger inserted. I have tried to recalibrate the battery gauge, but this didn't help. Any suggestions?

I should add that i have recently been using a non-lenovo 60w USB-C charger. Could this be the explanation?

In continuation of my last message, the lenovo power gauge icon in the task bar now shows a red x, but if I go into lenovo vantage and check the battery, it says that the battery is good and that power is 100%

How is it possible for Lenovo to advertise 18 hours of battery life when I can barely get 6 or 7 hours with the battery saver on with the 4k screen?
