In BIOS it displayed Battery 97%, vs. when I logged in is fully charged. Why the discrepancy.....was it showing battery health?

Thanks.

Batteries degrade over time (you'd be surprised how quickly). Maybe the bios is showing battery health has degraded by 3%. Your 97% becomes the maximum and shows as 100% of the capacity left.....does that make sense?
Could be an overcharge protection built in

As you have a Dell, there's a little app called Dell power manager. It's one of the few Dell apps I keep on a system

Exactly, just like my cell's battery, charges to 100% but after 18 months app shows health as 91%, degraded by 9% in that time.

Maybe more discharging frequently like once weekly to 20% should keep it at 97%....:unsure:

Thanks.

Your milage may vary, but a lot of laptop manufacturers suggest doing the following on occasion to sync the battery level indications. To do so, perform these steps:

1) Plug in the laptop and let it charge completely.
2) Reboot into safe mode.
3) Set the computer to boot normally (not in safe mode) for the next time you boot but remain in safe mode for now.
3) Pull the plug and let the computer run until it loses power.
4) Plug in the computer and reboot normally.

Hopefully that helps!

Exactly, just looked at my iPhone, battery health is at 87% but it'll always charge to say 100%, But that's only 100% of the 87% that's available :unsure:

3. Boot normally immediately after safe mode?
4. Loses power to 0% turns off or less......like a charge/discharge cycle to sync. Occasionally do a drain, charge discharge on my cell

Thanks again!

They say charging to 100% degrades battery much quicker vs. charging to 80% less wear tear...at least for cell phones!

Unplug and let it run until dry in safe mode
You can use MSConfig to set it to boot normally at the next reboot
Plug it in and reboot and charge normally

How long is safe mode after a full charge?
Or immediately reboot from safe to normal mode and run it till it powers off?:rolleyes:

While in safe mode run the battery flat and turns itself off, then plug it in and reboot normally

Personally I don't care about my cell's battery since it costs hardly $30/- that's one reason that I charge to 100% with a wear of 0.96 per charge cycle.......
