Hello everyone , i ve been wondering since i saw the conservation energy mode in lenovo settings , because i do 3d modeling and i use my pc for long days , so i have to charge it 3 or 4 times a day ,wich will reduce the number of cycles (by 3cycles per day);or use the conservation mode and plug the ac all the time ?
so my question here , is this conservation mode would have an impact on the battery life ?

Hi wassim320 ,
Most users on Windows 8 have Lenovo energy manager to prolong their battery life.
Its main task is to prevent overuse of the battery limiting it to less than 100% (default at 60%) so that not all the components of a lithium battery are exposed thereby having longer usable elements for a longer life since battery are consumable parts.
In Windows 10 , same power management protocol are integrated with Lenovo setting downloaded as a metro apps of microsoft store to gain the same power management and battery control.
This is designed specifically to Lenovo users that needs the machine powered at longer periods so the more that battery life can at least be controlled in periods that it goes idle .
Using the ac adapter switches power need from battery to ac via smart chips lessening the discharge rate of battery but doesn't require it be always on ac .
Laptops are still mobile device (to have a computer on the go) as its main purpose. But if you have access to an ac power , this save your battery life with conservation mode working for you in the background (others would even remove their battery eventhough we have such softwares and smart chips because heat would still play as contributor to faster battery life).
More about the softwares here on this article and how it can help users.
Hope this help answer your query.

IIRC, The new type of battery will count the cycle differently from old type one.
I need to fins more infoemation on the battery type. But new type of battery (start using about 10 years ago, I think? this is kinda old already. lol) will count each cycle when the battery recharged hit 100%. Example, if first time you have use 50% battery and have 50% left. This will not count as cycle but only a half. If you recharged it and the next time you have use 30% and recharge again. This will count as 80% of the cycle. So, if your battery recharge count hit 100% this will count as 1 cycle.
BUT!!, as conservation mode is only made for who plugged-in ac power and did not use the battery for a long period of time. This will help discharge the enegy storage on the battery and help conserve the battery life.
There are even a story going on in my country that you have to remove the battery when the recharge hit full capacity to help conserve battery life... well, that is only half-true. Because the battery will stop recharge when it hit 100%. So, no more power is going in-or-out of the battery. Also, the removed battery will still have full capacity, if you did not use it for a long time there will still be an impact on battery life.
PS. Also, DO NOT used your battery until it is down to 20%!! This will have a very high impact on your battery life. I have done it and only a week (I only use it until 10% and recharge it 1 time a day, so total of 7 times) my battery life going down from 2 and a half hour to only 1 hour when full capacity.

Thank you for your answer spidey101,
For me it s windows 10,so lenovo settings it s already installed on my laptop,this is actually where i saw the conservation mode.
As i said , i use my laptop for a very long periods of time , so i won t enable this mode until the ac adapter is plugged to the pc , wich i think from what you said it s good for the battery life .
Unfortunately for me , if i want to remove my battery ,to protect it from high temperatures,i have to open the computer ,because y50-70 batterie aren t removal like others ,well it can be removed ,but i don t want to open it for the moment , to not lose the warranty...but i think for this next 3 months i ll be fine with the temperature problems,because it s cold right now ,most of times my pc is very cold from the outside as well as the inside.

Homin,thank you too ,
For the record ,it s li-ion battery with 4cell ,60wh and 15v.
dont worry for the cycles , i try to do it correctly ,when the system tells me to connect the ac adapter i shut down the pc and connect it until it s fully charged.
You re right ,when the pc is running and plugged , when it reaches 100% of charge ,the ac stops automatically to transfer power , i checked it by touching the ac adapter after 20min from 100% , it was cold .
For me ,as i said in last answer , i can t remove my battery ,except if i opened the pc,so what i think:I ll use my battery sometimes (short sessions) , and for a heavier use,i ll enable conservation mode , with ac plugged of course , to have more battery life.
And finally ,to answer to your idea about discharging it more than 90%, well i made a mistake last week , i ve been using my pc for 2-3hours ,then i saw that i have 15% left , i said to my self i ll plugged when i reach 10%; but suddenly i reached 6% , i turned it off immediately and charge it to 100% ; do you think this will have an impact on the battery life , because in the webs and forums it s said that we shouldn t discharge it over 90% , and some manufacturers says we shouldn t discharge completely (to have 0%).

Hi wassim320 ,
About removing the battery , you really don't have to unless you want to be very cautious about this because again new battery technology would have an electronic configuration that safeguards battery life automatically preventing such things like overcharge and undercharge risk that happens with battery before like a myth debunker .
Battery care is better than before so that there is no need to open the laptop.
Practices for lithium base battery (even for mobile phone ) would be to prevent over discharge and over charge but are still done on cases of doing manual battery reset gauge suggested to be done 2-4 months in some but for me better just to do it when there is an issue with charging thus avoiding normal functionality (nothing to fix when nothing is broken).
