Heya,

 

 

 

I have a Sabre 15 notebook from Gigabyte, The battery lasted for over 4 hours when new and now it can't even brush past 2 hours on the most economic settings. This is watching 1080P video from the SSD.
It has a 1060 and an I7 so it uses power but never was this bad. I do admit I do not use it on charge that often, Generally a movie or show every odd day of the week.
Just seems super low now. laptop is now 12 months old but I didn't expect it to get this bad. It never lives on AC power but I do game with AC power connected and then when I am not using it I have it disconnected.
I generated a battery report which I uploaded here: https://filebin.net/4emosmpd0tjqpdf8 

 

Any input is appreciated.

 


Cheers

In the time it took me to write this and generate the report I went from 100% down to 87%.. 
I have since set the processor state to maximum 50% and disabled the nvidia GPU when on power, Jumped up to 3 hours now but that is at idle with just this reply being typed.

Is anyone aware of any bench marking tools to gauge battery life or how ever?
PCMark 10 doesn't include it for free..

Cheers

I think there might be some linux tools that let you benchmark battery.

 

 

Generally most of the generic batteries that gaming laptops use aren't smart enough to report on battery health or the like.

 

 

For power saving its usually down to low screen brightness, low performance, low cpu voltage and disabling nvidia discrete (if you can) through optimus.

 

 

I remember doing a bunch of tweaks on a Sager laptop with a 970m before realising just having monitoring on the nvidia card would have it drawing power. I think it was recommended at some point on the notebook review forum to invest a bigger, quality battery if you wanted it to last.

Hey,

 

 

 

I already have my Nvidia GPU only set to be active when certain applications are open, so unless I am in a few specific games it is 100% disabled and i can see the voltage is at 0, usage etc etc via MSI Afterburner.

I have also set my processor maximum state to 50% when on battery too and it runs at 50% as well. I also made it disable turbo on battery and also dynamically change its speed. HDD is also not operating during battery use unless I am watching content from there.

Would having 5G network connected over 2.5G streaming content make it far worse with Chrome?

Cheers

I always found Chrome a real horror for chewing through battery life, especially when streaming video. That said, if you have always used it and still notice the useful battery capacity drop by half in a year, then that is pretty poor.

 

Presume you can see no other "energy thieves" running in the background when you bring up task Manager and check what is using CPU and disk?

This is a tough one, as usually the warranty explicitly states no warranty on battery.

Not sure how the CGA would view this.

Maybe start by contacting the retailer?




Swype on iOS is detrimental to accurate typing. Apologies in advance.

Under Win7 & WinXP there was a clash between the battery hardware and windows battery management. I am not sure if it was been fixed or continues with current versions of hardware and windows.

 

The hardware would guestimate from past useage, what the battery life was, and Windows would never let the laptop get to 0%. This meant the hardware saw decreasing usage and assumed it was deteriorating battery, recalculated the apparent "lower" battery capacity and it went in a vicious decreasing circle. By disabling all the auto shutdown, auto hibernate features laptops would often run for hours after the battery monitor reported 0%. I have personally seen laptops go for 2 hours after 0% battery was reported. With a few "real" cycles to the "real" 0%, the hardware progressively relearns the true capacity of the battery. Try it running some non-mission critical stuff.

Not sure how power efficient the radio is operating in either 5 or 2.4.

 

 

Chrome has been mentioned by a few of the *nix and macos users as a power thief. The apples switched to safari, windows to edge/IE (the horror) and nix to whatever else they had available.

 

 

Still I wouldn't put it past manufacturers of laptops to only expect those packs to last a year. Default ones aren't held in high regard in the notebook community.

Could it be the software you've installed doing things in the background taking battery?

Yeah Chrome is the main user when I am on battery and streaming, Otherwise it is the current app used for playback. But I have always done this and only in the last 2-3 weeks noticed a sharp decline. I could play Kerbal Space Program at 30FPS on max battery saver from AKL to BNE without a problem. (The A380 Didn't output 180W or around there for my laptop charger to work lol) But that proves my laptop was good for 2 hours under load even with the discrete GPU operating.

Did you see the file from the battery report I linked? Why would my capacity seem to rise over time? Is this the windows glitch you are thinking of?

It could be, Windows battery reporter seems pretty hopeless. Any other better tools apart from spying via task man?

It's a PB Tech Northshore purchase, like yeah I could try. I did have the dead pixel issue and they offered me a new replacement on the spot but I couldn't be bothered transferring everything for three dead pixels (Now 6). Could I use 6 dead pixels in under 12 months as a replacement request and pay the different to get the 12 core?

Hi Coil

 

 

 

When it comes the laptop battery life, it's best to keep the charge around 80%-90% and don't leave in the charger.

 

Basically, the batteries chemical set-up doesn't like to be full as the electrolytes need room to 'move' and having the constant trickle charge on the battery will use these electrolytes up faster.

 

Hope this helps.

 

 

 

Also, we can get replacement laptop batteries if you need.

Hey,

 

 

 

Thanks for the heads up. Its kind of hard with a gaming laptop and not wanting to do a battery out ordeal like some do.

 

Suppose its a trade off you got to make!
I will be looking for a battery in 3 months no doubt!

Cheers
