Well we could live with that... I got a bit better, but mine is currently a REALLY minimalistic setup, and was with zero screen interaction, so that was to be expected.
But in the order of 1% / hour would be what I'm used to see WITH the sim mounted and online on e.g. 22.1.
@TeZtdeviceInteresting idea with the Aeroplane mode, I will try that overnight WITH the sim physically mounted. ADD: After 11 hours in Aeroplane mode it was down to 94%, so roughly 0.5% per hour. Certainly not impressive, but tolerable.
Will recharge, and see what the day brings, but has not got my hopes up high..... ADD II: still bad out of Aeroplane mode
