No battery lights showing charging if over 95%?

When I charge the P3S batteries from a low level (say 10%) to 100% I first get 1 LED blinking, then 2 then 3 and finally up to all 4 and when the charge is fully complete - the battery lights go off completely.

I unplug the charger, and if I touch the button on the battery - I get 4 full green LED lights.  Fully charged.

So after leaving a day or more I then used the battery to start-up the P3S just to show some friends.  I did this a few times, but didn't start the props turning - just showed how the P3S started with the camera, gimbal, lights etc.

But this morning I thought I'd better top-up the charge so plugged it in and nothing.  Same with the second battery.  Both batteries show 4 full LED lights when the battery button is pushed.

So I am concluding that although the batteries may not be at 100.00% they are probably 96-98% and so at that level, when plugged-in to the charger, this is considered essentially 100% so no further charging takes place.  

IS THAT CORRECT?

Tonight when I plug-in the battery to the P3S I'll note the battery charge read-out.  I don't think I've ever read 100% -- mostly it reads max 98%--- but I assume that the charger won't do any more charging after that 95% level is reached?  (Also guessing that the intelligence here is not the charger, rather this is in the battery itself-- is that correct?)

Thanks for any comments.  

Best regards,

You're correct, if the battery is almost fully charged (I'm unsure the exact threshold) it won't charge back to 100%; it just sits there doing nothing.

However, if you plug it in to the charger and then turn the battery itself on (1 quick press, 1 long press - like normal) the battery will charge to 100%. Once it's finished charging the battery then turns itself off.

Genuine method to top up, recently recommended by a DJI moderator in a forum post.

I wouldn't make it a habit of doing that.  Why not go out and use your battery so you can properly cycle it.  Remember, cooking the battery shortens its life.  Charge it and use it.  Store it at ~50% charge.

If you are above 95% consider it fully charges. Yes, you may not get 20min, may get 19, but does that reallt matter? Remember that the batteries do have a finite number of cycles, so if it's almost full, it may be better to fly it out, and recharge then. You are also aware of the battery setting in DJI GO app, that will put your battery into discharge state if not used for x days? I usually see it set for 4 days, and it's a setting PER BATTERY.... That is to prevent puffing from a battery that has been full ycharged and not used for a while....

Also a great comment!  I have my batteries set to begin discharging after 5 days-- may reduce that to 4 days.  Really appreciate the comments!  Thanks!

Super!  Thanks and as a Mac guy since 1989 I tend not to read manuals!  lol-- actually I do and remember seeing this when I first got my P3S about 6 weeks ago-- will have a relook at the manual.  And I think that what others have said about charging and then flying instead of topping-up is probably good advice.  

Really appreciate it!
