Double Battery Lifespan [ZenFone Max3 5.5]

Question.
This feature will help our batt phone to last double its normal batt span and it can be use up to 500 times only?
Am I Corret?

Thanks.

When you activate "double battery lifespan" it uses an alternate charging method which is slower, however less damaging. Lithium batteries love a slow charge. That is why it says it will decrease device usage between charges. Sort of an odd way to phrase it. In other words, after five hundred charge and discharges you will only have lost half the usable capacity you would have lost had you not been using "double battery life". Got it?
