This may appear a bit concerning at first, however, it is just another security feature from apple that aims to provide better privacy services. I turned off optimized charging and it will still only charge to around 80% or so. Low power mode is enabled:
If This Icon Is Red, Then Your Iphone Has Less Than 20% Charge.
I put her battery into my phone and it showed it was 99% charged. The yellow battery on your ios device means that it is in low power mode. When i got home from work i turned it off and it shows a gray battery and then a yellow triangle with exclamation point.
Turn On The “Set Automatically” Switch.
Nope, your iphone doesn’t have a bad liver and is not suffering from a jaundice infection, it. If this icon is yellow, low power mode is on. The yellow battery indicator represents an activated energy saving mode.
When Low Power Mode Is On, The Battery In The Status Bar Will Be Yellow.
Yellow is battery saving mode green is battery is currently charging/connected to a power source white is iphone is using battery as power source You'll see and the battery percentage. It means it isn’t getting full power usually from not using the proper usb wall plug (tablets require 2 amp chargers) basically it means when the screen is on it isn’t charging, it will charge with the screen off (at least mine does) but slower than normal, with the screen on it wont lose charge but wont gain either (.
Go To Settings On Your Iphone’s Desktop.
My iphone has a issue. So what does the yellow color mean? To fix this, you should try moving your iphone or ipad to a cooler location, which would be more conducive.
