leaving ipad plugged in all day

[charlituna]

You forgot to include the rest of the Apple statement:
"iOS 11.3 includes a charge management feature to help maintain battery health, which monitors iPad for use in these situations and, as required, reduces the maximum charge level. The battery indicator will display the charge based on the adjusted maximum battery level. The maximum charge level will revert back to the previous level when iPad is no longer connected to power for prolonged periods and as conditions and battery health allow."

In other words, apple knows this and takes care of it through their software.

the fact that they did this tells us that yes it is bad to have the iPad fully charged all the time. they actually went in and adjusted the software to figure out that it hasn't been off the charger in an extended time and actually stop charging it until it gets to a safer level.

and before the tin foil 'they just want to take money from us' crew jumps in, it's just the opposite. keeping the battery at more like 50-60% reduces the change of a swollen battery which would potentially mean you having to pay to get that fixed (depending on the age of the iPad)

It says it helps maintain battery health. It doesn’t indicate it resolves this issue completely. Your best bet is to still unplug and discharge regularly.

it's very possible that this management software is also accounting for that. the batteries probably are not one solid battery cell so the software can adjust which cell is being charged and which is discharging so that it cycles through each of them in turn. which is kind of the point of letting it discharge via use etc. in fact Apple no longer says that you have to let it completely go to zero. you just need an aggregate discharge of 100% per month. that suggests that charging management software is already working on all devices. otherwise 10+10+20+5 etc wouldn't do the same as 100 in one shot

should I leave my iPad plugged in all day in the white zone?

You generally want to unplug the cable once the charge is complete.

You can't hide from the fact that li-ion battery chemistry doesn't like fully charged batteries.

iOS 11.3 was updated to include charge management because there were reports from kiosk users and teachers (who use charging carts) seeing swollen batteries from iPads. It still keeps the battery slightly below 100%, but that's still not great for battery health.

Looks like I'm late to the party but can confirm this. IT Support for healthcare chain and am having to pull mounted ipads off the walls all over with swollen batteries. Some screens were bubbled out a few mm only, others > inch and looking ready to burst.

All were running iOS 10. All on 24/7 in kiosk mode locked in 1 app.


Are you still kicking around here JPack?

I'm going to replace batteries and update iOS if nothing else is damaged within the ipads. Wondering if I'll be fine moving forward with the changes mentioned in the newer iOS battery settings or if I should invest in smartplug/timers to only have them on power for X hours a day?

Apple doesn't explain how their charge management feature works, so I have no idea how it works. But I suspect the issue is resolved. If I had to guess, the feature probably reduces the battery max charge capacity to 40 or 50% if it detects iPad being charged for long periods of time.
