Premature battery wear on new iPad mini?

Got a new Mini 4 around the third week of April and I ran the Battery Life app yesterday and see that the battery life wear is down 2% to 98%. When I ran it new back at the end of April it was at 100%

Is the app accurate? Isn't 2% wear for a infrequently- moderately used tablet (not heavily used) a bit worrisome? It's only been roughly 1.5 months.

Thanks.

Battery wear is like Windows estimating the time until an install is finished.

2% wear will have absolutely no impact on your battery life. None. Lithium technology is intermittent, unreliable, and therefore the health should be considered with a hefty pinch of sodium chloride, especially when it's in the 90%+ range. A battery doesn't charge to 100% of its capacity anyway, otherwise they'd last about 4 charges. It charges to 97% or so, and iOS interprets at 100%.

Part of the trouble is that you ran the battery wear app when, seemingly, you had no actual concerns about your battery life. You had no reason to run it. Obsessively checking the 'health' of a battery will only put you in a poor frame of mind, and negatively impact the enjoyment of your device.

Use a device as you normally would. There is no right or wrong way to preserve a battery. They will always deplete naturally. If eventually you are having poor battery life, then do something about it.

That is waaay too small an amount, and you've had your device for waaay too short a time for it to mean anything. Battery wear is an estimate. Try checking it again in several months to a year. Or better yet, unless you notice a significant decline, don't worry about it all. Otherwise you will spend your entire time owning the device being anxious about every percent drop and imagining that your battery is worse than it is. You will not enjoy your iPad this way.

It's like being a hypochondriac. If you worry too much about your battery, you WILL convince yourself that there's something wrong with it.

Lithium ion battery chemistry degrades over time with or without use. And even with perfect care. So it's only been 1.5 months to you personally but that poor Mini 4 has been on stock shelves at one warehouse or another for a year now that's 12 months of the chemicals going bad over time.
