How long should a battery last in a notebook?

#Post
1

I bought online from Levono NZ & it was delivered in late 2017.

Tech did a battery report on it

As per battery report : capacity 30000mwh full charge 21,760mwh .

It's not charging properly. Only charges up to 37% & then runs down quickly.
Sometimes it doesn't charge at all.

It's a Levono Yoga 310

Battery is dead, time to replace it.

Depends a lot on how it's used and charged. Hubby has a laptop about 4 yrs old and the battery is DEAD. Mine is maybe 3 yrs old and the battery is fine. Different machines/different usage cases etc etc.

Just checked the receipt for his lappy it's 4 yrs old almost exactly. HP.
Mines an Acer and 2 yrs 8 months old.

We've had other laptops and the batteries do eventually degrade. 4 yrs is ok but sometimes you'll get more.

The 2 new laptops I have had recently (first one was sent back because it was faulty) had a battery app with them that controlled the battery voltage for different applications. It recommended that the charge limit be set to 80% if you were going to have it plugged in all the time. Having them plugged in all the time at 100% charge apparently degrades and shortens the battery life.

If it only charges to 37% and runs down quickly it does sound like your battery is prematurely faulty but may have been caused by leaving it plugged in and charging all the time.

I still have an old, old Sony Vaio & an ever older Acer. The batteries are fine in those but too slow to be of any use now. I would have bought the Sony Vaios prequakes as I bought 1 for me & 1 for my son. I think I got a $100 discount for buying 2. In the first 2010 EQ my son had a plastic tumbler of water beside his at his flat that spilt on it. It would've cost more to repair than replace. Mine must be over @ 12yrs old now. They don't make them like they used to or are they just more power hungry these days?

Well looked after the battery should last a lot longer but most people don't know how too. Unlike lead acid batteries which should be kept fully charged for longevity, lithium batteries in laptops need to be kept about 50% which is about 3.85 volts (Fully charged they are about 4.2volts ) Lots of people have them plugged into the charger all the time which is not good for them. Or leave them flat which is equally bad.

In my experience batteries last around 2-3 years if abused (e.g. kept plugged or discharged in all the time etc)

That's the minimum. Anything more than 5 years is a bonus

How do you mean discharged all the time? Do you mean when you don't use it much?

Yeah, goes flat, put in a cupboard somewhere and forgot about

No I never did that. I use it most days but did take my Chromebook for a 5 day holiday to Coast so didn't use it then. The longest it's gone without use since I got it would have been 1 or 2 day. It was the bees knees until it wasn't!

What he means is, a lithium ion battery does NOT like be left dead flat or fully charged all the time, it shortens the life of them considerably.

Try draining the battery until the notebook shuts down then wait 10 min start the notebook until it shuts down this is resetting the memory ie % of charge its showing.
Then but it on charge with notebook turned off until it's fully charged.
I would also check your charger as most people treat their chargers terribly it might be a broken wire in the charging cable. Regards to the other poster they are right to a point about running the battery flat is not good but it's hard to always charge to 80% all the time which is optimum for battery life cycles as for me I run my phone off the charger when I can. The less you charge the longer the battery life cycles so if you are always going from full charge to flat you will have less charging cycles than going from 100% charge to 50% before charging it up.
Lastly think of your battery this way let's say your battery has 1000 cycles from full to discharge.
If you charge your battery at 50% to full you will get 2000 cycles and if you charge your battery at 75% you will get 4000 cycles.
So how you treat and charge your battery determines its life I'm talking about lipo batteries which are in phones laptops pretty much everything these days.
I hope this helps you understand batteries a little bit better thanks.

Many devices have software which enables control of the amount and rate of charge. Phones/laptops often allow the owner to set charge to a max of 80%. It's very common.

Batteries always have a very limited warranty anyway. It's a given that they deteriorate over time and it's expected they have a limited lifespan before requiring replacement.

The 'Problem' is merely that the OP was trying to ascertain, (as per the thread title), "How long should a battery last in a notebook?"

They obviously didn't really know. They've been educated and advised now and will undoubtedly replace the battery.

its a bit like asking how long should a pair of shoes last.

Yes thanks I didn't really know. I used my Sony Vaio for over 7 yrs without the battery failing. I never had a battery fail on any device I've had which includes 4 notebooks & 1 tablet. The Tech in KL thought it should have lasted longer.

I stick to Levono only bc the techs can do logmein & see what's the issue is & fix it for me. The last Lenovo notebook I had ( was much less expensive)
there was hardware fault so I replaced with Yoga 310.

I'm now using an ASUS Chromebook which I got at good price due to being relatively brainless.

The techs can use LogMeIn -or a similar remote control program- on ANY computer.

Huawei were able to do that on my phone it was incredibe they were able to see what it was running or had been running and were able to test it at the same time all while he was in another part of the country.
All I had to do was put in a code in a certain part of the support app.
Just incredible.

Yes my son did something similar to remotely take control over my computer from Melbourne. I didn't know other computer co's had free techs but wouldn't you had to have bought directly from their company? Not from a company like Hardly Normals ( sic.)

Well during lock down perhaps hardly normals and snoel lemons are running remote assist ?

I doubt it's free. Nothing much is.

It is free if you buy it direct from Lenovo.

With my ASUS Chromebook I have a free 1 on 1 tutor at an agency the runs activies for ppl with TBI etc. I'm sure 1 of them told me there was no way to get the shift key to stay on. I'm glad I checked here.

One of staff there is a complete idiot & told me that it would require complicated programming to change 2 keys that were reversed, The other switched the keyboard to the US setting. It took 3 seconds to do it!
