Over the past few weeks (months, idk?) my phone (Pixel 8) gives me a message that says “Charging on hold to protect the battery” when the phone is not plugged in. The notification stays forever until I select “override” to dismiss the safety feature. It will not charge (if I later plug it in) until I say “override”. When I say override, it will let me charge, but I will still see the notification again later, so it appears to be a temporary override.
This morning, I saw the notification pop up while I was using the phone. It was in my hands, not plugged in, and did the animation like I had just plugged in the phone to charge. It was at about 45% battery, so it also seems to have nothing to do with battery percent.
Am I just charging wrong, or I don’t understand how smart charging works, or is this incorrect behavior? In normal circumstances, I charge the phone overnight. Since this has begun, I have begun leaving it off the charger overnight and instead charging it earlier in the evening for a bit then removing it before bed. I’ve noticed recently that it only charges to 80%, so it is usually very low when I get home.
Sounds like something is damaged or defective. If it’s under warranty, I’d send it in for repair, otherwise I’d just live with it.
So, just asked Google Customer service about it. The answer does not make sense to me, but they said “Adaptive Charging on a Google Pixel phone may show the charging symbol even when it’s not plugged in because it charges to one hour before you unplug it.” They also told me several times that “You shouldn’t worry about it”.
This is not very satisfying, and doesn’t make sense, but it wasn’t going anywhere. I’m going to try turning off adaptive charging, because maybe it’s just really confused what my schedule is?
No, that’s nonsense. Adaptive charging uses your plugging-in habits over the last 14 days and your alarms so that it can charge at the slowest possible rate to reach 100% one hour before your predicted unplug time. It should never show the charging symbol when not charging (as far as I know, anyway).
You can turn the adaptive charging off if you don’t use it, but I think your phone is still going to think it’s plugged in when it isn’t, and still only go to 80% unless you override it.
Yep, I agree with you. I think the customer service representative just didn’t know what to make of the problem. They picked up on the fact that I use adaptive charging, and everything I got after that from them was telling me that this is how it works. I reiterated that it is doing this when not plugged in, but then we were going in circles, so I just said thank you and left.
If it happens again, maybe I will get a different rep and have more success.
No, it fast charges to 80% then restarts the (fast) charging to hit 100% at the correct time. At no point does it try to slow down the charge.
I don’t really know where this misconception comes from, the description in settings is pretty accurate to what it does:
That quote doesn’t support what you’re saying. The page that screen links to, however, says this:
https://support.google.com/pixelphone/answer/7106961?visit_id=638632664567131340-1406770578&p=adaptive_charging&rd=1#adaptive_charging
So maybe it does. Unfortunately Android doesn’t chart battery level while charging. I just plugged mine in and adaptive charging turned on, and Ampere shows about 1.5 A, so not trickle charging.
It would be nice if Google actually stated what it does.
I have a cable that shows wattage and my 7a goes all the way to 80% at pretty much stable 20W unless it’s overheating. The final 20% is a bit more random, but that’s true even without adaptive battery turned on - the top 10% won’t go above 5 W at all for me, for example.
To me “waits until you need it to fully charge” sounds closer to “waits at a safe level until it needs to fully charge” than to “charges slowly”, but English is not my first language and it might sound to me like a stronger statement than it really is.
But my point was more that nowhere does it state that it will slow charge (which I agree I didn’t properly communicate).
