| Dec 3, 2015 at 9:37 | comment | added | Vinayak | @ChrisH that does seem useful. I have a Lenovo notebook with the energy management app but without the button to override the current setting one time. @.siblynx may I suggest installing TLP on your device, if you able to? It supposedly helps you get more juice out of your battery by doing advanced power management. | |
| Dec 3, 2015 at 9:27 | comment | added | Chris H | @Vinayak maybe that's a different version, because I remember a button to fully charge it this time. That would seem to be a useful feature: optimise for battery lifetime, but allow the user to override if necessary, without them forgetting to turn the setting off again. | |

@ChrisH I think you're referring to this?. I believe you can have the same effect on Linux by installing the tp_smapi kernel module but I haven't tried it yet.

| Dec 3, 2015 at 9:16 | comment | added | user529094 | @Vinayak Well, this little poor machine (Asus X101CH) even has poor Linux support, and I use it mainly as a debug & testing tool. It even has soldered RAM and CPU. It's hard enough to access even it's hard driver and I do not want to disassemble it now (but I did that earlier once). So I let it be as it goes now. | |
| Dec 3, 2015 at 9:07 | comment | added | Chris H | @Vinayak, that's true. There is (on Windows) a tool to tell it to charge fully (e.g. before a long period without access to power), but it's buried somewhere in the options, even though it's a "do it now" tool rather than an option. The Lenovo I know that does this doesn't yet have Linux on it. | |

| Dec 3, 2015 at 7:23 | comment | added | Vinayak | I'm not sure how it works on Linux, but usually on Windows I get to 100% even though the battery has a bit of wear. I'll have to look into that | |
| Dec 3, 2015 at 7:21 | comment | added | Vinayak | Batteries age over time and a 22% drop in battery capacity for one that's been used over 2 years is not surprising. It's nothing that you need to worry about though. Not until battery wear guess up to 50% or more. | |
| Dec 3, 2015 at 7:20 | comment | added | user529094 | I understand that battery itself will not return back to 2200mAh 100%. Just confused with hardware indicator - will it consider new 1700mAh capacity as 100% and how to teach it. | |
| Dec 3, 2015 at 7:17 | comment | added | Vinayak | Certain Lenovo computers have software that cuts off power to the battery at 60% charge and maintains that battery level (even with the notebook powered off), which apparently increases battery life. You could do this manually but I can only imagine what an inconvenience that'd be. I am unaware of any software programs that can achieve the same effect on other computers. | |
| Dec 3, 2015 at 7:11 | comment | added | Vinayak | That's normal. It is unlikely that you will reach 100% again as your battery capacity has dropped by almost 22%. You should however, refrain from performing battery calibration very frequently and try not to drain your battery down to 10% or less as I recall reading something about that being harmful to your battery life. | |
| Dec 3, 2015 at 7:06 | comment | added | user529094 | Yes I see that last full capacity dropped, however I attempted calibration ten times since I noticed that, both with and without OS running to no avail. I once flushed it down to 0% even laptop was not able to turn on then charged. Still stuck at 90%. | |
