    Hello everybody


    I would like to be able to set the level up to which my battery charges (for example 80%) and the level where it starts charging (for example below 40%) in order to keep the battery alive as long as possible. I usually use the laptop connected to the power and if I use it on battery, then just for max. two hours so it is fair enough to have even just 50% of the capacity.

    Does anybody know if there is a solution for that what can be used on all kinds of laptop brands, for example a little program? I couldn't find one until now, they all just do other useless things but not what I wish.

    I really don't understand why I cant say myself how I want my battery to be charged. I hope we can find a solution for that, for any laptop. That's the reason I post this Question here and not in the Samsung Area.

    I know there are other Brands, for example Lenovo, where a function like this sometimes is implemented.

    Thanks for any help and already thank you for answering me!



    My laptop: Samsung Ativ Book 8 with Win10

    What I did until now:

    I looked for a solution and found out, that on older Samsung laptops there was something called "Battery life extender" which was also possible to enable/disable in the bios. However, on newer laptops like my one they removed this option completely.
    In my bios there is nothing about that. And if I go to that Samsung Settings installed onto my Windows, there is just an ECO-Mode what I dont need at all.

    So I tried to download and install that "Battery life extender", but it just doesn't work on win10 I guess.
    I also looked for other programs but none I could find which can solve my problem. They all do just other unnecessary things like energy saving blablabla...

    In this forum i found a thread what cares about the same problem but doesn't really solve it for new Samsung laptops: http://forum.notebookreview.com/threads/where-is-battery-life-extender-samsung-notebook-windows-8.703322/http://forum.notebookreview.com/threads/where-is-battery-life-extender-samsung-notebook-windows-8.703322/

    I just signed up here for this issue because until now i spent around four hours googling around for solutions and i can't believe that it is so difficult to manage that. I guess it might be quiet tricky to access the battery charging options and maybe its different on every laptop brand and series...but i really hope to find a solution and also help people who have the same problem in the future. It is not just about my battery but to being able to keep control about what is happening in our devices. I hate to be unable to change settings.
    Hope some can understand me.

    Cheers!

    Hi.

    It`s years since i had a Samsung notebook but i had quite a few of them, and yes they had a battery saver that stopped the battery charging at 80%.

    Hopefully MOD John Ratsey who watches over the Samsung notebook section knows a lot about Samsung notebook and might be able to answer your question.

    Try sending a PM to him or post in the Samsung section.

    I'm going to move this to the Samsung forum as it's more likely that someone there (although it's not very busy these days) may know if there is a fix. The charging is controlled by the BIOS so the fix has to be made there.

    I recall Samsung saying that they had improved the battery / charging process so that the battery life extender facility was no longer needed. In reality, they were probably getting too many problems from users complaining that their batteries didn't charge fully or the computers didn't run very long on battery. Both Dell and Lenovo (and maybe HP?) still offer battery charge management options on their business notebooks but not the consumer models, presumably on the basis that those who use the capability know what they are doing.

    Exactly which model of the Book 8? What is your normal battery usage pattern. If the computer is normally plugged in to mains power then just leave it plugged in. Once it is charged up the the charging will stop.

    Thanks for the replys and moving the thread.

    The model is NT870Z5G-X29

    Ye I think Samsung's just taken the easy way...making it more annoying for people like me who have a bit passion about technics.

    Yes, normally its plugged in but sometimes I take it to school, however there I don't use it much, and basically just for texting with low battery usage. So i could usually easily serve two days with a cycle. Now i use a cycle every day and some say that the number of cycles makes the battery life.

    I know that the charging stops at 100%, but the aging of the battery over the time is faster the more it is charged and there is that issue with the temperature rising when the charging approaches 100% which is said to be not that good as well. As far as I read that heat problem was the actual reason for Samsung to make that "battery life extender" tool.

    I had a look into the Bios, there was nothing about that. And actually that Bios doesn't look like a bios, there is already a quiet graphic surface with even the touchpad working.

    While I agree that the overall battery life can be extended by avoiding charging to 100%, most notebook manufacturers have tweaked the charging rules to substantially reduce the charge rate as the battery approaches 100%. You can check what happens on your notebook using a program such as BatteryInfoView. It's also possible that newer batteries have been configured so that 100% on the gauge is not 100% of maximum capacity but a bit less in order to give longer life at the expense of maximum capacity.

    Manufacturers express the battery life in charge cycles without actually defining what it means. Some batteries report charge cycles to BatteryInfoView but many don't. However, after many years of thought on this subject I have concluded that a charge cycle involves substantial discharge / recharge. Draining a battery from 100% to 60% and then recharging it is more likely to be half a charge cycle than a whole one.

    You might want to check the wear on your battery. To do this you need to put it through a full charge-discharge-recharge cycle. There is a calibration utility in the BIOS which discharges the battery until empty and avoids Windows shutting down / hibernating the computer with several percent charge remaining (but the accuracy of this amount may drift over time as the battery wears).
