So for my ipad 4 which is about 4 years old, when I get only 78.6 % charge capacity it should be counted as normal because its much older then 2 yrs even though I only have less then 400 cycles?
Got a tip for us?

No but Lithium Ion batteries chemically degrade over time even with perfect care and use. So in 2 years 100% may only really give you 80% use time.Can you damage the battery if you leave it plugged in at 100% charge?
The worst thing you can do to any Lithium Ion Battery is
#1. Charge it constantly. Or too frequently
#2. Let it run down to 0%
My iPad 4 has 77% left after four years and, iirc, 530 cycles or so. That proves that time degrades battery. It shouldn't be anywhere close to 77% if it had let's say 530 cycles and 6 months, but it has a long while until it reaches 1000. (Who knows how low will the capacity be when it actually reaches 1000, it could take 4 more years or more.)
Wow, I did not know the batter cycle life of the iPad or the iPhone (I thought the iPhone would be at least 500 cycles).
Suddenly, this makes the decision of purchasing a new iPP when the models are refreshed a very good idea.

"Charge Cycles3
A properly maintained iPad battery is designed to retain up to 80% of its original capacity at 1000 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs."
Somehow, I always thought it was 200 full cycles. Maybe that was just my old MacBook Pro battery.
I know this is an old thread, but just downloaded one of those battery health apps and my ipad mini is approaching 1200 cycles with only a 12% drop in capacity, i had no clue how many times i have charged that thing, never a problem with it.
