Series 11 slow charging, why?

[ndouglas]

I have not changed anything re: the wall plug, it’s a good one from Anker that before this new S11, charged my S10 just fine (and quickly). However I am noticing the new watch is definitely not always charging very fast. Just now it has been on the charger for almost 1 hour. During that period, it’s gone from 30 or 40% to…. 62%.

Isn’t this a little strange? Any ideas why that would happen? Has anyone else had similar issues with the Series 11?

I am accustomed to it going to 100% during the 30, 40, up to 60 minutes that it charging while I shower and let it sit for a while after that.

Does the battery graph on the watch, general, battery, show like an orange color for this time period? Or green? Orange indicates slow charging.
And a re you charging with the pick that came with the 11?

Is it best to charge with the newer puck?

I've used an older one over my last couple of Apple Watches (SE) but I don't think they supported fast charging.

I'll need to buy a new USB-C charger and some cables but I might just buy a stand if it'll cost about the same.

According to Apple fast charging requires the USB-C puck,

Fast charging requires an Apple USB-C Magnetic Fast Charging Cable. You can identify this cable from other chargers by the USB-C connector and the aluminium around the magnetic charger.

I would expect the older USB-A puck to charge the Series 11 as quickly as it charged the Series 10 though. As jz0309 said, check the charging graph in Settings, Battery. If the graph is yellow then the watch detected a slow charger was being used, it might be worth checking if the watch thinks the charging was intermittent but that might not be obvious from the tiny graph.

For comparison, my Series 11, charging with the bundled USB-C puck and a third party USB-PD power supply, charged from 12% to the full notification on my phone in 57 minutes yesterday.

I do not know if Apple changed anything with the series 11 charging puck compared to previous models, but certainly you need a USB-C puck/cable for any kind of fast(er) charging.
Years back, there were quite a few folks reporting that 3rd party chargers caused issues. While I haven’t seen posts about that in the last couple years or so, it’s an unknown.

Me, I charge both my U2 and my S7 on the puck that came with my S0, sure it shows “slow” on the charging graph, but I charge overnight so don’t need “fast” charging.

Thanks for the replies. Yes I use the S11 new charging cord and puck it came with. I felt a little weird switching it since the S10 being used before just barely 2 weeks ago would have been probably fine, but I figured maybe there’s some tiny change where the S11 cord is better, faster, or whatever.

I haven’t noticed the color beyond red when it’s super low, and green otherwise, on the display of the watch screen that is... I’ll keep a closer eye on the graph color in the watch itself, which I don’t look at normally but I’ll make a point to do so, now.

—^ very nice, yeah that sounds like what it _should_ be doing.

Most of the time I put the watch to charge it’s only down to 30, 40, or 50%, so 30 - 60 mins charging is plenty of time to shower and etc. then put it back on (I appreciate the sleep and health data so I wear it 24/7 besides when charging). So it’s odd that just yesterday and 2-3 other recent days before that, I had to keep checking it and noticed wow it’s still** not close to 100%? Usually I don’t have to monitor it much since I just put it back on when it’s semi-close to 100%, but the few times it slow-charges it is quite noticeable since it is soooo slow.

Today was fine, so I’ll keep monitoring and hope for the best, and maybe update this post in a week or so if anyone is interested.
