Laptop battery life...

I stand corrected :sigh: . C cells, probably still has charge as I remember not much used C cells! ;)

Hi All, Not really being a big laptop person, I am seeing with my work Lappy the battery is good for around 10 minutes from a full charge it drops extremely fast, I am talking 93% to 15% in the space of 10 minutes while not being used! (Outlook open, Teams open, Chrome & possibly Edge open) the thing is you need to plug it in to get any useful work done, I have got on to our IT dept about it ('Well run BatteryReport and get back to us'). Battery report shows the battery falls off a cliff. So are 'modern' laptops really bad at power management or does the OS (11 ver?) run really badly from a power point of view. Back in the day Laptops would last and last (I remember the first laptop I dealt with an Amstrad PPC512 used it on site for four day didn't need to charge it!) rant over Glenn
Back in the day I lugged around a Dell 17-inch XPS system whose weight was a real factor in airports. I downsized from that to an Asus 15.6-inch Core-i7 and had to buy an extended-life battery that only added to the weight. I used a wheeled laptop case to deal with all the crap you need -- it's not just the weight of the laptop, but the power block, the cables, and whatever. Now I use an LG Gram-16 12thGen Core-i7 that has amazing battery life and weighs less than a kilo. It's fast, light, has a great screen, and was a reasonable price. VStudio runs in a flash so I can realistically do on-site development when needed.

The entire laptop is 18 months old (warranty?)
Not generally known but for more expensive items one can often make a case to the manufacturer when there is an extreme failure reasonably outside of the warranty window. After all they don't really want you going around posting that your battery failed after only 18 months.

As I read this you have a device that has the same alkaline batteries in it from 40 years ago?
I stuck a set in PPC512 many years ago, last I heard it was still working. Got replaced a couple of years ago, the company Involved couldn"t change a lightbulb.

If something were draining the battery that fast then some things in the computer would be getting very warm very fast.
Well it was getting warm or hot around the area of the interface. Hence me getting a little worried.

Lithium batteries really don't like being kept at 100% state of charge (it degrades them). The way most people use a laptop ensures premature battery failure. My laptop spends 99.9% of its time plugged into a docking station (constantly charging the battery). I doubt if my battery will last any longer than yours. Laptop makers should add an on-line battery mode that charges (or discharges if needed) the battery to 30% state of charge. At this level of charge a lithium battery has a greatly extended shelf life. When you need to travel, you charge the battery to 100% and off you go. They wouldn't be able to sell as many replacement batteries if they did this so I don't ever expect to see anything like this. Phil Ouellette, BSEE

Battey's in general don't like 100% or anyother value for long periods. You try to tell non-EE people (marketing!) that they look at you like you are selling snake oil.:omg:

For some reason, "Laptop battery life" made me associate to a Duracell rabbit. Maybe that association is NSFW, thus not suited for the Lounge.
Religious freedom is the freedom to say that two plus two make five.
I often wonder did Duracell use the rabbit in Europe due to the Engeriser Bunny in the States?

My 2015 vintage Lenovo has battery management so I keep charge at around 55%. click of a button and it will charge full if you know travel is imminent. My new Dell work laptop also has Battery management. I have it also set to keep battery at 50% since it is plugged in and powered on 24/7 99% of the time. If I am not traveling, I will cycle the battery down to about 20% and then charge it back up and run it back to 50% again maybe once every 6-8 weeks.

When we were reviewing new laptops for the dev team, our CTO said that he wanted light laptops for when going through airports. I looked at him and asked why. I said that I've been on 3 business trips in 10 years of employment here. I don't care about airports, I want performance. In addition, many of us could use a workout. The airport argument seems to be the most American thing I've ever heard. We want bigger everything until we have to carry it.

That's because he was worried that the slightest IT person would injure themselves. It's all about exposure. If they go with the lightest devices, no one can hold them accountable for staff having to carry all that weight and injure themselves. IMHO, the best way to get around that would be to have three different models on the catalogue and let staff pick the one that suits them best. Then they choose. They make the choice around what they are comfortable enough to carry.

They last longest when stored at 40% of capacity. That is why everything you buy with lithium batteries comes charged to about that. Avoid storying batteries at elevated temperatures too. It is ok to freeze them, just warm them up before charging. Charging a frozen battery can destroy it.
