Hello,

I have a Asus ROG Strix gaming laptop. Model is GL704GW-PS74. I bought it brand new in 2019. I just recently upgraded to Windows 11 a couple months ago. I have been having a battery issues as of late, and I am not sure if it's because of the age of the battery, or because of something else going on.


I do mostly run the laptop on the power supply. I have the 'My Asus' app that keeps the battery at 60% while plugged in. It's an option that says "Maximum lifespan mode".
So, if I charge the battery up to 100%, I can run the laptop a good hour or so without any issues on the battery. If I don't charge it to 100%, it's random as to how long it will run on battery, but it's consistent.


For a while now, I have noticed the battery will not stay charged up after I do a full shutdown. I can charge it to the 60% and go to boot it up 5 hours later, and it will boot up, but shortly after, it dies. I have to plug it in and re-boot. But the thing is, after I charge it up for a while, I can unplug it from the power supply and it stays running for 45 mins to an hour, depending on how much it was charged.


Is there a reason why the battery would be draining after I do a full Windows shut down? I have gone into the BIOS and turned off "fast boot" and the went into control panel.power options and turned off Windows fast boot options as suggested on a couple articles I ready, but neither seems to fix the issue. Is there something else I should be looking into? Is it strictly a battery issue?

I know it's a couple years old and I have been using it mostly plugged in and this all could cause battery issues, but I can't understand why I can use it on battery after I charge it for a bit, but it drains after I do the full shutdown. any suggestions or help would be greatly appreciated. Thanks.
 
my money is on the battery.

the average life span for a Li-ion battery is between 2-3 years in my experience.
however you use it - always on charge, only charge when depleted, never fully charge, never fully deplete, blah blah blah - it's all crock.

unlike NiCd and NiMH batteries, Li-Ion do not suffer the old "memory effect" problem that plagued the earlier technologies.

it does however suffer from oxidisation as soon as the battery is made, nothing to do with recharges.
this oxidisation reduces the lifespan and charge capacity as the battery ages.
it varies greatly between units due to the usage of the battery, the electrolyte used and the quality of the material the electrodes are made from.
geeky article here; https://pubs.acs.org/doi/10.1021/jacs.0c06363#

in a new battery, I used to see about 2-3% drop in charge over a 24 hour period when the PC was off.
this gets worse as the battery ages.

yours sounds like it is losing 60% of it's charge within 5 hours, which either indicates the battery is really shot or even when turned off, something is still running, perhaps some sort of ASUS or Microsoft sleep, hibernate or standby mode even though it's told to "turn off".
