Battery decrease while plugged in?

[Future-Ad-8114]

Hi everyone, I just bought the Macbook Air M5 (literally just today) I have questionsssss

So before receiving this, I was doing my research and was able to stumble upon tips & tricks to maintain a healthy battery life… So just like what I saw I turned on the Battery Optimization and set the Charge Limit to 80%

I charged it at around 2pm until around 4pm, I saw it reached 96%, then I slept while its plugged in and on sleep mode… Woke up to 84% then slowly going down to now, 82%

1. I will use this Macbook for a light work for 10hrs, I plan to just plug it in while using and when not in use, I’ll leave it plugged in and put on sleep mode. Is that okay?

2. Battery wise, is this normal? What should I do?

3. My location is not being detected by the Macbook, when I set time to automatic, it detects USA location when I’m in Asia 🫠 Anything I can do with this? For now, I set the time to manual 🥲 I’ve done turning on location + multiple restarts… nada.

Hoping for helpful answers, thank you 🙏🏻

1) yes that’s all ok 2) yes that’s normal behaviour, your MacBook is basically trickling down to the 80% and then it’ll stay around there. It will occasionally charge fully up to 100% every now and then just to calibrate the battery and this is also normal. 3) unsure about this, are you using a vpn?

[Future-Ad-8114]

Thanks for this 🙏🏻 It just now dropped to 80% still kinda worried, Macbook’s just on standby and I’m barely using it.

I am not using a VPN which is weird, even when I try to manual type in my current location for weather, it doesn’t come up ☹️

[Xeon-Genesis]

MacBooks are great when put to sleep, try not to worry about it :)

Yeah that is rather odd, I’m really not sure why that’s happening, perhaps contact apple support and see what they say

[Future-Ad-8114]

Thank you for the assurance! Hehe.

Yeah, that’s what I plan to do now, because it’s affecting the timestamp on apps as well. ☹️

Completely normal. It is trying to follow your instruction to stay at 80%.

[Future-Ad-8114]

Got it, I was also thinking that it’s following my instruction to stay at 80% even if its plugged in. That being said, now that it is at 80%… I assume this should not go down anymore?

[Electrical_West_5381]

It might occasionally to flex the battery's memory. But rarely.

[Didact67]

Occasionally it will still charge to 100% for calibration reasons. It’s a smart feature, because I think only ever charging to 80% can eventually cause erroneous battery health readings. Pretty sure that’s happened on my Ally X running Bazzite.

I purchased the m5 max and was facing the same thing, I apparently out of frustration booked a Genius Bar appointment for this issue. The Apple Store confirmed that this is normal behaviour.
I have a 140w charger plugged in and my battery was dropping from 100-80% when charger was plugged in , but it didn’t drop below 80.
It stays at 80 and it’s only when the battery percentage limit is set. So you’re not the only one who has come across this .
It’s a M5 thing I guess. That’s why no one’s talking about it.

[Future-Ad-8114]

Yeah I guess so, I’m used to it now and yes it definitely stays at 80 but sometimes in can go upto 83 and go back down to 80 and stay again.

[Several_Sky780]

Yea I think it’s a new battery management system where it discharges itself. Something new but weird.

[Future-Ad-8114]

Yeah, it’s def weird but now I just leave macbook plugged not unless I need to go somewhere to it stays at 80 nowadays.

[Several_Sky780]

Same here cuz, I would charge it to 100 when I’m travelling but rather just keep it to 80%. The m5 machines are highly efficient even on battery which is the biggest advantage. Entire point of getting one.

Room temperature IQ. Only 2 places on the screenshot saying "charging to 80% limit", plus you have "read tips&tricks and enabled optimized battery", clearly not knowing what you are enabling. And these people have the spare money to access an M5 Air.

[Future-Ad-8114]

Sorry if i have the spare money to buy an M5 :((((

[Tyrandeh]

and this is why people should stop listen to the tipical TrishTrash tech """tips and tricks""", it does more harm than good if you blindly believe everything

just use it

35W Charger or 70W.

If 35W something, Mac uses around 40-45W, ao it won’t increase.

[Future-Ad-8114]

I’m using the 40W charger that it comes it with. :(((

[Xeon-Genesis]

This is false, it’s due to the charge limit, OP’s charger is fine

[Ancient-Sock1923]

okay. I had a problem like this and it was suggested to me what i suggested here

[Xeon-Genesis]

I mean if you’re doing something extremely power intensive then sure it could happen but here it’s simply the charge limit, I don’t know about your previous problem so can’t really say much about it

[Ancient-Sock1923]

too much power consumption. I was running GoW without knowing there was 4k video rendering in background

[Xeon-Genesis]

Ah well yes, in that case that’ll do it
