Dumb question but has anyone else had this happen? My 3ds never lost charge before HBing it, but after doing so it starts to drain the battery when the system is fully shutdown. I thought was just the battery being old (the since launch one, it being about 3/4 years old after constant use) got one from the Nintendo online store about a month ago. I checked to see and it showed 80% in the Rosalina menu a 2 weeks ago and just now I checked and its at 73% on a new battery after not being touched in 2 weeks. My old battery would be fine but randomly it would drain from fully charge to dead the next day over night after I HB'd it. It also has a weird ui bug/glitch where it will be at 40% in the RM but the main menu ui shows a full battery. Thinking I messed up on something but have nc as to what it could be.

i did make
post awhile ago about it but seeing as its happening to a new battery I'm stump'd.

It may say in Rosalina 73% but notice that the home menu is reporting the battery as full. If your console wasn't hacked you'd be thinking your battery was full even though it isn't. That makes me think that the battery is operating normally, and you've just become acutely aware of the battery level now that you have a more accurate indicator of it.
forgive if I say ask/something dumb (haven't sleep after work) but isn't it supposed to be different if its at 73% of 100? bc that's over 1/4th of the battery gone. Wouldn't the ui also follow suite and display 3/4th or is it something that has always been like this but I've never noticed? it drained 7% from not being used for 2 weeks after it was on 80% even then I tried a test to where it was 83% then charged it to 100 and it dropped while not being used. I'm tired as hell and could be misinterpreting the reply (happens more than I'd like to admit). sorry about the edits I've noticed to many sentences where I thought I typed but didn't
Battery indicators often lie about the exact battery level for the same reason car fuel gauges lie about how much fuel you have left. They'll keep indicating full for a while after a charge/refill because people don't like to see their battery level/fuel start dropping immediately when they just charged/refilled.
Unlike fuel measurement though battery level measurement isn't precise, far from it, and it gets less precise with a worn battery, so you can't trust an exact battery % indicator.
A battery indicator with 4 bars like that probably doesn't have the indicators set to 0-25/25-50/50-75/75-100 like you might assume. They might be set to 0-10/10-25/25-50/50-100 and in fact something like that is far more common. In a way it's more helpful because you know when your battery gets down to one bar and red, it's time to plug in the charger ASAP or save your game or risk losing progress. And most people wait to charge until the battery gets low anyway so not being able to see that you might've drained nearly half the battery already isn't a huge deal.
