Durata della batteria

[SamueleMattia]

Buonasera a tutti.

da pochi mesi ho acquistato un Laptop HP Pavilion 15-eh1000, processore RYZEN 7.

Utilizzando il notebook per navigare su internet e utilizzare Office (word, excel) la batteria, carica al 100%, dura soltanto 3 ore.

Secondo voi è normale questa breve durata, dal momento che la scheda tecnica indichi circa 9 ore di autonomia?

Grazie

"Good evening everyone.  A few months ago I bought a laptop HP Pavilion 15-eh1000, processor RYZEN 7.  Using the notebook to surf the internet and use Office (word, excel) the battery, 100% charged, lasts only 3 hours.  Do you think this short duration is normal, since the data sheet indicates about 9 hours of autonomy?  Thank you."

This is a complex question, because it depends upon how much demand you place on the battery.  If you play video games, you draw more power than if you just check email.  To conserve battery power and maximize battery life:

● Lower the brightness of the display.
● Select the Power saver setting in Power Options.
● Turn off wireless devices when you are not using them.
● Disconnect unused external devices that are not plugged into an external power source, such as an
external hard drive connected to a USB port.
● Stop, disable, or remove any external media cards that you are not using.
● Before you leave your work, initiate Sleep or shut down the computer.

You should know:

1)  BIOS:  Keeping the notebook plugged in all the time will cause the battery to enlarge (swell) over time, and limit battery life.  The intent of HP to run on a "battery only" was to charge the battery up to 100%, then disconnect and use the laptop normally until the battery discharges to 20%, then charge the battery again.   The 9 hour battery life quoted by the salesman is the extreme case, with minimal activity, and is based upon maximum capacity of 100% battery charge down to 0% battery charge. 

However, battery life can be even less over time if you keep the laptop plugged in all the time:  this will cause the battery to swell.  If you intend to keep the notebook plugged in all the time, you should update the BIOS to the latest revision.  In the BIOS you can set the battery charge ***not to exceed 80%*** - this will prevent the battery from swelling and ruining your battery life.  Of course, you should only discharge the battery down to about 20% before charging again for maximum battery life, so this limits your available time away from the charger.  Operating the battery long-term in the range from 80%-20% = 60% x 9 hours = 5.4 hours.  No one will tell you this - it is information that is difficult to find - it is not in HP's User Guide - it can be found on the HP Community Forum. 

2)  Only use the official HP battery replacement.  Why?  If you buy a cheap Chinese battery, the Chinese discount battery people won't tell you this, but the Chinese battery capacity is really only 74% of the HP battery.  The battery cells are physically smaller, (the battery weighs less: 213 gr HP battery vs 169 gr Chinese battery), which is why they can sell it cheaper.  I've taken the Chinese batteries apart and can confirm this.  However, the same operating conditions apply for Chinese battery charge capacity (80%->20%), but now the usable battery charge is 74% less, or 5.4 hours x 74% = 4 hours (on a new Chinese battery). 

Yes, the HP battery is more expensive, but with correct treatment of the battery, it should last a long time.  You should replace the battery BEFORE the notebook goes out of warranty, because HP will no longer sell the official HP battery in their warehouse after the warranty expires (at least they did obsolete the battery for me), and you'll be stuck with only a cheap Chinese battery replacement. 

Battery replacement is a skilled, delicate procedure, so get someone skilled to help you.  You only need the replacement battery, a Torx T5 screwdriver, and a #1 Phillips screwdriver, and the HP Service Manual, but you have to ***gentle with the parts***.  If you replacing the battery yourself, and somehow damage the computer, you can possibly void your HP warranty, so waiting until later in the warranty period may be advisable.  Or have a skilled person do the work.  If you are not paying attention, you can put the battery in backwards.

3)  If the battery charging levels are not respected (80% ->20%), the battery life will decay quickly, as you have experienced.   You should know there is also an "HP Command Center" software program that is not well known, that will allow you to put the notebook in a "Comfort" mode, which slows down the fan and the CPU to slow power consumption, but still allows acceptable performance.  This is not mentioned in the HP User's Guide.

4)  There are many unnecessary program calculations and telemetry going on in the background of your notebook that is consuming your battery, with no productive result for you.  People call this unneeded programs "bloat".  If you search for ways to "Debloat" Windows 10/11, it will remove unneeded programs.  If you search for "turn off background telemetry", you can save your battery life for programs you actually use, instead of wasting power sending Microsoft/HP/Google/McAffee antivirus uploading your websurfing and purchase history and sending you advertising.  You may want to ask for help performing removing background telemetry task, or look at the videos on YouTube on the subject.  Turn Privacy to maximum to save your battery charge.  Avoid using OneDrive - keep your files local - until you are plugged back into the charger.

5)  There is a "HP Fast Charge" feature (select products only), but fast charging comes at a price of lower battery longevity.  Slow battery charging will give you longer life.  You can charge as fast as you like up to 50% charge, but then the charge should be slowed down.  Your HP Adapter's ability to provide charging current will influence how fast the charge will be.  A smaller, less powerful adapter is better for battery life, but it takes longer to charge and may not be powerful enough to drive the laptop while using it.

6)  To monitor the status of the battery, or if the battery is no longer holding a charge, run HP Battery Check in
the HP Support Assistant app: 
a)  Type "SUPPORT" in the taskbar search box, and then select the HP Support Assistant app.
b)  Select My PC, select the Diagnostics and tools tab, and then select HP Battery Check.

If HP Battery Check indicates that your battery should be replaced, contact support.  Or order a spare replacement battery and have someone skilled to replace the battery.  The "HP Parts Surfer" website is the best way correctly identify the replacement battery along with your product ID and serial number.
