What is the best use of battery life?

Question

What is the best way to use battery life when constantly working on a laptop?
Is it best to run from a wall outlet and occasionally let the batteries recharge and discharge?
Or constantly charge, and then remove the power and discharge?

Answer 1

For Li-ion:
Optimal charge range for extended life: 30-80%.
If you want to remove the battery (store it separately), then charge up to 50-70%. There are constant disputes about this, I personally tend to charge about 50%, or approx. 3.7 V, if it is possible to control the voltage.
When storing, do not forget to check the charge level and recharge from time to time - deep self-discharge also kills lithium-ion.
If you want to keep the battery inside (built-in UPS), then look for power management software from the laptop manufacturer, in which you can configure the start and end charge range.
Set the same 30/80, work from the outlet, when the battery self-discharges up to 30%, it will charge up to 80%.
For some vendors / lines, this may be in the BIOS.
By the way, in the BIOS, also check for an option like FastCharge and the like - increased charging power. If it is, turn it off.
The options "constantly charged, slightly discharged - immediately charge to 100%" and "charge to 100%, turn off, work, charge again" will use up charge cycles earlier than you would like.
If an outlet is at hand, they are best avoided.

Answer 2

Perhaps many will not agree, but, in my opinion, you should not bother with all these attempts to somehow help the battery at all. The lithium-ion battery ages, degrades naturally on its own, even whether it is used or not. Why this hemorrhoid, if its resource is still not significantly extended? What depends on the person - unless you freeze the battery. And the rest should be used as convenient.

Answer 3

If the battery is of good quality, then no matter how you charge it, it will work well and for a long time. And if the battery is of dubious quality, then all sorts of tricks will not particularly prolong its durability.

Answer 4

1. Prescribe the transition to charging percentage by 80 ... 90 (usually ≈95).
2. At least sometimes give a discharge-charge.
That's all we can do.

Answer 5

1. Lithium batteries do not like to be kept discharged (40-80%). Those. you need to strive to ensure that the battery is always as charged as possible (preferably 100%)
2. Lithium batteries are very capricious in terms of charge-discharge (unlike acid, for example). Therefore, in any laptop or phone battery there is a charge-discharge controller that definitely does not allow you to recharge the battery or greatly discharge it. Thus, there is no need to remove the battery when working from the mains and you should not be afraid to discharge it completely (of course, if necessary)
A simple example from real life. The laptop is 7 years old, the battery was taken out 2 times during the repair, almost all the time the laptop worked from the network, i.e. the battery was 100% charged. The capacity dropped by 20% (instead of 5 hours of operation a little more than 4), the laptop is 5 years old, the battery was stuck in, poked out, charged using special methods from the Internet. the poor guy is already dead.

Answer 6

turn off the charged battery (although for greater safety it is advised to charge up to 80%) when the laptop is running from the mains.
I have a laptop at work permanently. The battery is in the bag, I used it from ~ a month ago, when I went to the object with a laptop. before leaving the battery charged up to 100%.
after leaving up to 80% (by eye) and turned off.
if there are no more trips for a couple of months, then I will take it out, recharge it and put it back in the bag.

Answer 7

Notebook 13th year. I did not remove the battery, it almost always works from the outlet.
Two hours on the battery still lives for sure
