Does the Core M3 model charge slower than the i5 and i7 models?

Is the battery take longer to charge on the Core M3 SP4 compared to the i5 and i7 models? Is the charger underpowered on the entry level fanless M3 model?

Both models are around 2 hours 30 minutes for a full charge (sources: anandtech, winbeta and my own core m3 SP4

Thanks! What kind of battery life are you seeing on your m3 SP4?

Solid 6-8 hours when doing office work or surfing.
With Wi-fi off when reading or doing annotations in e.g. Drawboard PDF is 10+ hours on a battery saver configuration.

My experience pretty much matches Notebookcheck's numbers from their review:

No, it is just 4.5 hours when surfing with Wi-Fi with last update.
