Hi,
As far as I understood, the battery life of the Apple Pencil Pro should be something around 12 hours…

I leave mine attached all time to the iPad Pro M4, because this is how it’s intended to be… and it seems to be always charging with the ligthning symbol.

That being said, when is use it, the battery seems to go down a few percents in few minutes. I never used more than 10-15 minutes at time, but by then it’s something around 80-85%. If I use it for 1-2 minutes it goes down to 97-98%. Is it normal? With these figures, I doubt it could last 12 hours, but neither 2 hours…

Maybe it’s the normal behaviour. I have Apple Care+ so I’m not worried, but just to know..

Thanks!

Same here, the pencil is draining too fast. It goes 10-15% of battery in just half an hour. I don’t know if it normal, but it should have lasted longer than that.

I use my pencil pro seldom so I do not leave it on the iPad charging all the time. When I do need it, it still has 50% of the battery after charging a week ago. If it is dead, it only takes a few minutes to charge enough to accomplish my needs. I assume you are using the pencil more than me, I think with the additional pencil function it is going to use more power. It sounds like it from what you have experienced.

it could make sense… thank you
 
Same here.

When the pencil is at 100 % it takes a bit but than it goes faster and faster to direction 0%.

Under 50 i have around 40 - 60 Minutes.

Have test it today complete: Not with drawing etc. Was work on Insta and was delete there many users etc. So I was wish with the pencil a lot. After around 3 h the thing was empty.

Do you have this like that too?

Please let me know.

let us know how it goes!
 
I am seeing that if I turn Bluetooth off on my iPad, the pencil battery holds longer. So it seems the range is longer and the pencil is connected and draining when not attached.

Anyone see the same?

With the original AP1, when I'm not using it I turn off the BT connection. It helps a lot. I spend days or even weeks without using the pencil, so it helped me. In my case it is worse (because of the lightning port) to connect again. For your cases, I'd say you would retain some of the comfort.
 
My Apple Pencil Pro can sit off the iPad for days without being used and every day I see the battery has drained anther 10-20%.

I thought it was supposed to switch off or go into low power mode? It's definitely not being moved in any way to trigger a power on.

I've been using my 11" iPad Pro with Pencil since release date in 2018. For years leaving the Pencil attached had negligible impact on standby battery. Over the last year or so the iPad began to be mostly drained after being in my bag overnight. I assumed the battery was reaching end of life - although that seemed odd as battery life otherwise seemed normal. I finally happened across some posts where this was also happening on new iPads. I tested it, and if I remove the Pencil, standby battery life is back to normal.

This worked perfectly for years. Unfortunate that Apple has broken it and never bothered to fix it.
 
I draw in Procreate. Batteries are completely discharged in 2.5 or three hours of work
 
If the battery is cooked it’s just probably never getting to peak voltage, hence getting stuck at 97ish %.
 
I have this issue too – I charge the pencil to 100% and regularly leave it off the iPad, not touched or moved for days and it has drained to like 50% without ever being used.

Is really annoying and wondered if I had a bad battery – happens all the time, even if the iPad is turned off too.

You’re supposed to disconnect the Pencil from Bluetooth when not using it or it WILL DRAIN. Hope this helps!
 
Using the Find My app you can re-add the pencil. That option disappeared once I removed it from Find My.
