Recommended battery threshold for P50/70?

Q: Recommended battery threshold for P50/70?

Currently, I have 85-95% charging and stop charging thresholds set up. But I think there might be some optimal setting to maximize the battery life. In the mean time, the total battery time is too short if I set the stop charging value too low. What do you use or any recommendations on the setting? Thanks.

Not sure where I'd submit a bug report, has anyone else experienced the following? I have my charging thresholds set to 80% in Lenovo Companion for my T470. However, it seem like half the time it will end up charging one or both batteries to 100%. What seems to happen is it charges to 80%, and it might sit there for a little while, and then a battery creeps to 81%, at which point it then gets charged to 100%. I'm assuming the code behind the threshold portion of the program is saying if charge == threshold rather than if charge >= threshold to determine when to cut the charging off.

I just bought a Yoga 730. I noticed that the Lenovo Vintage does not have the battery threshold in the hardware setting. How do I protect my battery from over charging or keep charging the moment I plug in the power adapter? I don?t want to just use 10 to 20% only and the battery start charging when I plug in.. battery will spoil due to the cycle of charge thing. help.

It's great that Lenovo Vantage cares about the lifespan of our batteries and offers us a choice of charge threshold.  But it offers no guidance what maximum level to set, except that it should be less than 100%.  Lenovo must have studied the effect of maximum charge on battery lifespan, and I wish it would share that information with us.  Higher maximum offers a convenience for most users, but they might be willing to trade some of that convenience for some increase in battery lifespan.  We need data in order to decide.  For example, does even setting the maximum at 95% have significant livespan advantage vs. setting maximum at 100%?  Without knowing such things we're just bumbling in setting battery charge threshold.

My P51 battery is set to start charging when below 80% and stop charging at 95%.  (Lenovo Companion> Hardware Settings> Power> Battery Charge Threshold> Start Charging When Below 80%> Stop Charging at 95%).  I have my P51 plugged in all the time.  The battery always stays at 95% charged, it never reduces down to below 80% and then automatically recharges back up to 95%.  Obviously the P51 will run the battery down when unplugged and then when plugged back in it will recharge back up to 95% capacity and stay there.My older T530 had the same settings as my new P51 does but it honors the charging perameters  set by the T530's Lenovo Companion's Charging Threshold....The battery charge gradually reduces to below 80% and then it automatically recharges back up to 95%...Thus "exercising the battery".                       My question is two fold...1.  Why doesn't the P51 perform the same way that the T530 does using the same Charging Thresholds?2.  Isn't it beneficial for a Lithium Battery to vary it's charge vs. staying charged always at the same level? Curious...Altoid666

A:P51 Battery Charge Threshold

My guess is that the power management works the same.  Probably, the T530's cells are slowly losing charge over time and when it gets below 80% it charges.  The new battery cells probably lose charge also, but MUCH more slowly.  When it gets below 80%, it will charge.  If you want to vary the charge level, unplug it for a few minutes, occasionally.  I think Lithium cells degrade over time, but I think the degredation speed has more to do with ambient temperature and number of recharge cycles.

Hi! I have X1C 5th 20HR. I was using it with the Windows 10 Pro which came built in. I was using it with the battery charge threshold option (95%).After that, I switched to Ubuntu and clean installed it. I tried to change it (charge threshold) also with Ubuntu, but I failed. The battery was only charging up to 94 % all the time. I was okay with it.Yet, after several months, I had to change back to Windows. Now I have Win10 Pro again, but this time, whenever I try to set up a threshold, it is set for several seconds, and after that, it turns itself off automatically. I tried it like 30 times already with a different threshold, with different levels of battery charge, almost with an empty battery, but no result.Is this behavior expected? How can I fix it? I will attach my attempt as GIF file

I have a T470s with two batteries where one discharges before the other. I was wondering if there is a way to set a threshold for when the laptop would move from using battery 0 to battery 1. The problem is my battery 0 has gone through much more discharge cycles than battery 1 (I think 20 to 1) and I want the laptop to switch to battery 1 when say the battery 0 reaches 40%.  Any advice would be great.Thanks

Hey guys, my IdeaPad U41 shipped with Windows 8.1. My work, however, requires me to use linux as my operating system. I got to choose which distro I wanted to use though, so I went with openSUSE. The problem is, that I can't figure out how to set or unset the battery charging threshold. It is currently set to stop charging at around 60% to preserve battery life. Since I'm going on a trip tomorrow, I need this limit out of the way as fast as possible. Does anyone know of an easy way to achieve this in openSUSE (tumbleweed)? I know that some Lenovo machines ship with linux by default, so I figured there ought to be a way of doing this... EDIT:So, I spent some more time, googling the issue, and foud this tpacpi-bat-tool. It is targeted at ThinkPads and I wondered if it would work on an IdeaPad as well. I hesitated trying it out yet since I don't want to mess anything up.Any help is greatly appreciated. (I couldn't find a BIOS option or anything.)

Hi,  As it is not good for the durability of a lithium battery to be charged above 80% , and unplugging the power once the laptop reaches 80% charge is not really an option: I am wondering if it is at all possible to set the battery charging threshold/limit/maximum to 80% for an HP Laptop ? (For example by using any software or sepcial setting) So basically a tool that stops the laptop from charging the moment in reaches 80%, in order to increase the battery's durability. Other manufacturers (Samsung/Sony/Lenovo...) offer certain battery control tools in order to maximize the lifespan of the laptops battery. Is there a tool by HP/for HP laptops?  I am sorry if this is a repost or if this question was already answered elsewhere. I use a HP Spectre x360 and Windows 10. Thanks in advance!

Hi everyone!After a month of using Ubuntu on my Yoga 2 Pro machine i realized that the battery is degrading when the laptop is continiously connected to AC.Dual boot with Windows is not an option - because to change the battery threshold you have to make a reboot and keep the space for windows on your ssd drive.So what have i done - i studied Super I/O registers values while enabling/disabling different Yoga 2 Pro management features like battery threshold, quick charge and usb charging and wrote a simple program which allows you to change this feautres from Linux. Find the project here:https://gitlab.com/mikoff/Y2P-PM/The program can set up different Yoga 2 Pro power management features and read their status.

Hi there, I have a question with regards to power management for my Lenovo thinkpad x1 yoga 3rd. I tried finding a solution to be able to manage the charging threshold points myself.However, anything I found points to either old solutions (Lenovo Companion, Lenovo Settings) or it doesn't seem to be fully working for my device and environment (Windows 10).I have ended up installing Lenovo Vantage from the Windows App Store but I notice that:- it takes a long time for the app to start (several minutes)- there is no "Power" menu item under HW I am not sure if the app is compatible with my device? For example, the Update System Drivers function doesn't seem to work at all. I triggered the same and the hour glass indicates gathering information but nothing seems to happen (I waited for more then 30 min).  So, as I usually work off the power supply and only seldom on battery, I want to be able to limit charging of the battery to a max of 80 or 85%. I found some instructions on tweaking registry settings but all they did so far is showing the battery icon in the task bar (but maybe that came with the Lenovo Vantage installation, I can't be fully sure).  I read several posts that the threshold settings are not necessary for modern / new systems but being an electrical engineer and having read up on the Lithium Ion Battery charging issue, I beg to differ!

Hi. I'm having issues with my battery threshold option. I want the battery to stop charging when it reaches 80%. However, it will never keep the setting on forever.

The laptop will not hibernate unless I Close the Laptop lid. I went into power options in the control panel and set hibernation to be activated when laptop was running on battery and reached low batt threshold of 20%. When the threshold is met, nothing happen.

Tried a different power management plan and configured the hibernations settings similar to the above, still nothing happened.

I dont remember running the disk clean up utility which I hear can delete the hyberfill.sys file which stops hibernation.

I went into CMD as administrator, and used the powercfg command with the

-h on switch, makes no difference, I even turned hibernation off (-h off) and then turned on again, still no difference.

Went into CMD and searched for the hyberfill.sys file in the c:\ file is present, I think its about 2GB in size.

Any ideas?

A:[SOLVED] HP Laptop will not hibernate when low/critical Battery threshold is met

An update, I think this may be battery related or perhaps even ACPI related?? Battery seems to have an issue charging, I dont remember this happening before. The power supply is working because its providing power to the laptop, but the battery wont charge.

Tried setting hibernation to turn on even when power supply is plugged in and battery is at low batt threshold, it still will not hibernate.

Only way it will hibernate is if you close the laptop lid or click on the start button and actually choose the hibernate option which is amongst the restart, turn off, sleep options.

I have tried to adjust the battery charging thresholds for my L720 using Power Manager 8. The idea is to preserve the battery by charging only between 46% and 50%. The system accepts these settings and shows them when the pointer hovers over the power manager in the toolbar, but forgets them every time the computer goes into standby or hibernation. This makes the settings pointless. I am running Windows 10 and believe that both Windows and the power manager are the latest versions available.
