Laptop Battery Longevity

[arjaybe]

I bought a refurb laptop - my first laptop ever - and I found out that it loses 15-20 percent of its charge per day when suspended. Is this normal or did I get an old battery in this machine? Obviously the info in my sig is irrelevant.

You can probably run diagnostics on the machine from the BIOS. That will give you a good idea. Leaving things suspended does use some power. Your number sounds excessive, but then I never suspend things. I deprive them of electrons so they might rest 'totally'.

[Nix Hard]

Wouldn't expect more than 6-7 days on standby myself, may depend on amount of RAM you have.
More RAM more juice used to keep little Eric the electron alive while sleeping.
Always thought of Suspend as a short time thing unless plugged in to mains power.

Haven't got Hibernation working on my lappy yet, will save that for next install with new MXlinux KDE version.

If @manyroads idea doesn't work for you, try playing a video looping at full screen brightness to see how long it lasts, then check your time against reported battery times from reviews of your machine.

Cheers NH

Okay, it's good to know that it's not out of line. I'll check the diagnostics in the BIOS.

edit: The diagnostics in BIOS are rudimentary. RAM and disk if I remember correctly.

I'm going to go back to keeping it plugged in when not in use. I stopped that because I didn't know if it was a good thing to do.

There are battery health applications. Mint has one, and I thought MX did as well - I'm in MX-KDE and the KDEInfocenter has some battery information: my 2-years-old LG Gram has a nominal capacity of 80kWh, but actual of 74 kWh, which is okay. I've had some batteries new and installed and their capacity has dropped dramatically over a couple of months, but these were cheap ex-China, as opposed to OEM which are probably also sourced from China but higher quality and worth the extra.

Thanks. I checked the KDE Info Center, but it doesn't show any kWh, just Wh -- around 48. I didn't see anything that might show battery health.

This is from your QSI at the top of your post arjaybe;
"Battery: ID-1: BAT0 charge: 46.5 Wh condition: 47.7/47.7 Wh (100%) volts: 12.7/11.4 model: 333-42-2A-A HV03048XL
type: Li-ion serial: <filter> status: Discharging "

Mine old lappy shows this; "Battery: ID-1: BAT1 charge: 23.9 Wh condition: 23.9/28.5 Wh (84%) volts: 16.0/14.4 model: COMPAL PABAS0241231 type: Li-ion
serial: <filter> status: Full"

QSI reckons your batt is good as, a practical stress test should confirm it.
As per my earlier comment.

Cheers NH

Does that mean that the nominal capacity of the battery is 47.7Wh and that it was at that when fully charged? It looks as if it might judging from what I found at the HP site. This is what I wanted: to learn how to assess laptops. Thanks.
