It is advisable to charge more often up to 80%.


Recommended Posts

I inquired of Microsoft Copilot AI:

"Does charging the battery from 50 percent to 80 percent more often, rather than charging it less frequently from 20 percent, result in a decrease in battery lifespan?"

The reaction implies the need for charging at shorter intervals. If somebody has a differing opinion, kindly provide the rationale behind it:

The effect on battery lifespan is influenced by several variables, but on average, charging the battery more often from 50% to 80% is less detrimental than charging it less often from 20% to 80%. The reason is as follows:

"Cycling Depth: Charging the battery from 20% to 80% utilises 60% of its capacity, whereas charging from 50% to 80% only utilises 30%." Increased depth of discharge cycles may lead to greater long-term wear.
Heat is generated while charging from lower levels of charge, such as 20%, since there is a larger flow of electric current. High temperatures have a negative impact on the overall condition and performance of batteries. Regularly charging the battery to a shallow depth (e.g., from 50% to 80%) produces lower levels of heat.

"Batteries undergo mechanical stress when they are being charged and discharged." Regular and superficial cycles reduce the mechanical strain on the cells.

"Cell balancing: Certain contemporary electric vehicles employ cell balancing techniques during the charging process." Regularly charging the cell helps to preserve its equilibrium.
Generally, it is more beneficial for battery life to charge from 50% to 80% more often. Nevertheless, it is crucial to adhere to the manufacturer's guidelines for achieving the most efficient charging methods.

Similarly, same principle may be used to phone batteries. I make it a habit to charge my phone every night, regardless of its current charge level. Additionally, I have adjusted the maximum charge limit to 85%. I have not had any issues with my phone battery for many years.

It is intriguing to determine the precise charging regimen that is most favourable. However, based on my experience with different battery types such as those used for tools, lawnmowers, electric bikes, and phones, I have come to believe that maintaining the charging levels between 20% and 80% whenever feasible offers the greatest likelihood of achieving a prolonged and beneficial lifespan.

Apple has included selectable charging choices on the iPhone 15 Pro. One option limits the charging to 80%, while another option, called 'Optimum', mostly follows the 80% charging regime but allows the device to charge beyond that, up to 100%, as it deems necessary. When the screen metre reaches 20%, I typically charge the gadget. However, if it is late in the day, I like to wait until the following morning to charge it, since I avoid leaving batteries charging inside overnight.

I have transitioned from consistently powering down my phone throughout the night to opting for Aeroplane mode, which allows my watch to track my sleep patterns when I want to observe them.

While visiting a cycling forum during the early stages of Ebikes' development, there were several debates on the 20%-80% charging regime. Some individuals argued that the battery chargers were sophisticated enough to consider 0%-100% as really being 20%-80%. I have always been sceptical about the truth of that statement, but it is irrelevant since not all charges possess the same qualities or capabilities.

I agree with your statement that not all chargers are created equal. Avoiding 'rapid' charging until absolutely required will significantly improve the lifespan of your phone's battery, since excessive heat generated during fast charging can have detrimental effects on battery health.
I use 'smart' plugs to charge my iPhone15 Pro and watch. These plugs are programmed to provide a low wattage charge (5W) for a duration of 2 hours, namely between 5 and 7am, in order to improve the charging process. If I determine that they need further charging during the day, I will provide a brief and rapid charging session.
In addition, I have established 'Shortcut' automations that use Siri to verbally notify me when my battery level exceeds 80% or falls below 20%.

This information is valuable to me since I own both an EBike and an older iPhone. However, I much want the iPhone 15 Pro for the reasons you have mentioned. I was unaware of the Optimum setting. I would readily and enthusiastically agree to it without hesitation! I hope that future electric vehicles (EVs) are equipped with an Optimum setting.

Kia already has built-in configurations to restrict the maximum charging capacity. (user specified, as it is appropriate)
It should be noted that it is not possible to fully charge a battery to 100% due to the buffer between the overall battery capacity and the useable capacity.

The question is fundamentally flawed. The answer is contingent upon the specific kind of battery you own.
There is no one solution that applies to all categories.

Kia cell balancing is performed by charging the battery to its maximum capacity using an alternating current (A/C) power source, as stated in the manual. It is advised to carry out this procedure once a month in order to maintain the battery's optimal performance.

Conclusion of the day. The depreciation of your battery will not be noticeable for many years.
Observe the leafs that are over 10 years old, together with their basic, compact batteries that lack temperature management, but continue to function. What is the expected lifespan of a Kia battery with thermal management?

I prefer relying on Bjorn Nyland's empirical testing and outcomes for older vehicles, rather than an AI-generated response.

At the end of the day, I am recharging my automobile to levels that are appropriate for my current requirements. The responsibility of dealing with the battery will be left to others when the automobile reaches a much older age.

Charging our plug-in hybrid electric vehicle (PHEV) to less than 100% would greatly diminish its practicality, thus I always ensure it is charged to its full capacity. There is no decrease in the distance that may be travelled without recharging the battery after 18 months or 12,000 miles. Based on my comprehension, maintaining the charge state at a high level, rather than simply charging to 100%, exacerbates cell damage, such as dendritic development.

Significant advancements have been made in understanding battery performance in recent years. However, despite these improvements, experts acknowledge that there is still a considerable amount of knowledge yet to be acquired. This reminds me of a speech by Donald Rumsfeld, the former US Defence Secretary, where he confidently discussed the known and unknown aspects of a subject.

Impressive speech that thoroughly bewildered the audience, providing just a glimpse of its full content.
