hi guys

just wanna ask how long does a laptop's battery last on the average? my laptop's model is HP Pavilion dv5000 and recently i began to suspect that the battery does not usually last any longer than 2 hours. is that already the average battery life or is there something wrong with it already? thanks in advance

A quick way to turn the thread's observations into a definitive answer is to measure the pack, not guess from runtime. Several posters noted widely different run times and age effects (, , , , ). The single most useful fact is the battery's current full‑charge capacity versus its original (design) capacity: if the full‑charge number is much lower than the design number the pack is worn and the short runtime is expected.

On Windows (8/10/11) an official report can be generated from an elevated command prompt:

powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"

Open the generated HTML and compare DESIGN CAPACITY with FULL CHARGE CAPACITY. Battery wear percent can be calculated as:
wear% = (1 - FullChargeCapacity / DesignCapacity) * 100.
On Linux, upower or reading /sys/class/power_supply/BAT0/uevent will show similar values; OEM BIOS or vendor diagnostics on HP systems also report battery health.

If the battery meter looks wrong rather than actually low capacity, a one‑time calibration can help: charge to 100%, let the system discharge to automatic sleep/hibernate, then recharge to 100% without interruption. Do not regularly deep‑discharge Li‑ion packs — calibration only needed occasionally.

For better runtime without replacing the pack: lower screen brightness, disable radios (Wi‑Fi/Bluetooth) when unused, close background apps, and lower the CPU maximum processor state in the power profile. If the measured full‑charge capacity is substantially below the design value (commonly treated as a practical threshold around 70–80%), consider replacing the battery with an OEM or reputable equivalent and check the pack model printed on the battery. If replacement does not restore expected runtime, run vendor diagnostics (BIOS/HP Support Assistant) to rule out charging or motherboard issues.

Well, it depends on the type of battery, size of it, the screen size, hard drive speed, etc. On average, a notebook should get from 2:30 to 4:00 if I'm correct. My notebook, on "Power Saver," get's 4:00-ish usually.

Yo,
Also age and if you leave it plugged in a lot affect the life of a battery. In my experience, batteries just simply "run out" after a while (hence my battery for my Panasonic)
Also my *newer* Compaq Armada M700 says it will last 3 hours, then after it does down to about 60% it just dies...
So it depends.

The best battery life i have seen quoted is 5 hours! But normally average battery life varies on age and make model of the laptop. Normally it is around 2/3 hours for an average battery life.

My laptop gets a little under 2 hours of battery, which is the Dell C600. However, I've used a notebook that get's about 6 hours of battery life, and one that got 8 hours of battery life. If your want to increase your battery life, you probably want to add additional batteries. Also, I use Ubuntu, so I get a little less battery life.

My HP only gets an hour.
I think you'll find a battery rating at the HP site.
