Switch 10: Battery life unimpressive

Thanks for that;  I've tried the Sleepstudy you suggested, and found that the Switch was losing about ½% capacity per hour, which is more than an InstantGo device should; Wikipedia quotes Microsoft as saying 'systems must not drain more than 5% of battery capacity while idle over a 16-hour period '. However, it's not an amount I'm going to lose a lot of sleep over myself, though I might try some of the hints you can find here, like disabling lock screen notifications. Maybe they'll help you?

My major concern - & the reason the Switch is going back for repair - was the length of time taken to charge.  At over 6 hours, it's far too long, and shouldn't be getting affected much by any InstantGo drain.  That's why I was asking for someone else to run BatteryInfoView to see if anyone else's Switch showed the same sort of time.

Cheers
