Ive noticed in many threads people asking questions about either their flight batteries or their controller battery.
The above link has a lot of usefull information related to lithium ion batteries and will hopefully help to answer a few questions that people may have

Planned obsolescence, or built-in obsolescence, in industrial design and economics is a policy of planning or designing a product with an artificially limited useful life, so it will become obsolete (that is, unfashionable or no longer functional) after a certain period of time.[1] The rationale behind the strategy is to generate long-term sales volume by reducing the time between repeat purchases (referred to as "shortening the replacement cycle").[2]

Producers that pursue this strategy believe that the additional sales revenue it creates more than offsets the additional costs of research and development and opportunity costs of repurposing an existing product line. In a competitive industry, this is a risky policy because consumers may decide to buy from competitors instead if they notice the strategy.

That table basicaly states that the more you discharge your batteries for example flying untill you get a low battery warning the less charge cycles you can expect to get out of your batteries.
This simply equates to less flights over a period of time but longer flights. As opposed to getting more shorter flights over the life of the battery

To put this in simple terms if you do lots of long flights your batteries wont last as long as they would if you did lots of short flights.
Also the manner that you fly in has a dramatic impact on your batteries.
If you want your batteries to last longer then you are much better off to fly low and slow this will minimise the current draw on the battery during flight.
Try to get in the habit of not pushing to 100% on the joysticks.

Thats correct treat the drone gentle and you should gets lots of flight time out of it.
Ive only ever flown my drone in sports mode a cple of times and have no intention to ever doing it again.
The strain on the drone and battery is very high when you start fliying around at those speeds

"if you do lots of long flights your batteries wont last as long as they would if you did lots of short flights."
But as the table show charge cycles, you might get more total flight time by not think too much about it. If you were planning for use only 10% at each flight a lot of your battery usage would have been used on warm up, waiting for GPS etc. ;-)

I wasnt meaning that you should only do 10 minute flights. If you concider the figures in the table you will notice that optimal discharge is around 50% this will give the best longevity and overal use from the batteries.
So for instance if you were to fly your drone conservatively you should get a decent amount of flight time.
If you were to fly at extremes ie 100% on the sticks your flight times will be conciderably reduced before you get to the 50% battery point

Surely, no modern manufacturer would use such tactics.  I mean, really.  Reputable companies like Microsoft, Apple, pick any automobile manufacturer, basically any tech industry, are strictly altruistic, aren't they?
