I'm a bit confused, I never had any battery die like that on me. I am currently using almost 5-year old T440s which has two batteries (internal and removable) and they are both still about 80% of their initial capacity. My laptop currently says it will last 8h on fully charged batteries which in my experience is fairly accurate.
I am using this laptop every day at work and at home. I am lugging it to every meeting, I am lounging on the sofa trying to get up to date with news and email. It has VMWare Workstation installed on it running at least one vm with Ubuntu at any point in time.
The ONLY two rules I follow is to 1) never allow battery to run very low and 2) make sure the laptop never uses a lot of power by trying to remove the culprit whenever fan starts to spin without apparent reason.
The laptop is on AC power as much as possible, whenever possible. I always alow it to charge to 100%. Whenever laptop is less than 100% I will make sure to connect it to AC as soon as practically possible.
Now, X230 is another premium laptop from Lenovo and it was debuted less than 2 years before T440s. It looks improbable to me that the difference in longevity can be attributed to some advancement made in that short time. I think taking good care of laptop (not letting it run hot or run out of juice completely) is much more significant effect here.
- Synaesthesia 8y agoI think it really depends on how many cycles the batteries have gone through. You say you keep yours on AC most of the time so maybe that’s why.
- lmilcin 8y agoWhat I meant is that laptop spens large portion of the day discharging, doing work. But I rarely let it get below 50% which is when main 6 cell battery starts running out before switching to internal 3 cell one. I unfortunately don't record the usage of my battery but mine would be different from the author of the article. In mine, I guess, you would see say 80% of days not going below 60% of charge. While I could technically last entire day on one charge bI never venture from home without charger and I always let it charge even if I have just few minutes between meetings. I also use the regular 65W charger to charge large battery which charges slowly (but I guess it helps maintain lower temperature).
- Synaesthesia 8y agoWell if you only discharge it partially, that only counts as a partial cycle, which helps keep your battery good. It's good to let it get completely flat every now and then, I believe...
- Shikadi 8y agoYou're confused why your batteries lasted longer when you took excessively good care of them? I don't think I'd be confused if a 30 year old car engine with low miles and proper oil changes still ran well
