How to Enhance battery life

[abubakarsufyan]

To enhance battery life or optimal use of battery of my Probook 440 G5, kindly guide me in following:

I use the said laptop in my office and home where all time electric power is available. Now suggest me:

1. when I am using laptop, should I plug in all the time even after battery is charged full or

2. I should remove the adopter after full charge and use the laptop till battery is discharged to 15 or less% and again plug in to charge full and so on ... or

3. Any other way of charging/discharging, for best/effective use of battery, please

Easy question.  When AC power is available, keep the laptop attached to the adapter and to the wall AC power.

Lithium-ion batteries last longer when kept at near full charge.  Repetitive charge/discharge cycles are not conducive to long battery life.

Thanks dear .... Thats what i was looking for

I agree with @Cheyenne4's answer. Lithium ion batteries are damaged most by depth of discharge, so anything you can do to minimise depth of discharge is important. If you are going to turn on the system and can connect external power, I would always do so.

Ideally you do not want to keep recharging lithium ion batteries to the very top, which is why systems will often not start charging if the battery is something like 85% or 90% charged already. If you have only discharged the battery to 80% and do not intend to use the system again for 3-4 days, I would consider not connecting up power until you need a fully charged battery or you want to use the system when you have external power available. On the other hand, deep discharge is much worse than full charges, so it's better to charge too often than not to charge. I certainly wouldn't store any lithium ion battery for a prolonged period without giving it a periodic charge.

Wear on lithium ion batteries is inevitable, not least as they deteriorate over time irrespective of use. The best you can do is delay that wearing process so far as possible.
