Is it modded? If so, enter hekate , goto tools, and check battery info. Diviide capacity design, by capacity full to get a percentage of your battery health. Example:I have a problem witch my switch!!!It drains the baterry very fast, it drains 500 mA I think that's not good at all, and I already replaced the battery (sorry for my bad english)
look at this :/You see it draining 500ma in hekate? That's not normal, usually it should be around 100-200ma depending on model (oled/v1/v2). also post a screenshot of battery info in hekate, it could just be a calibration problem
If you do a Google search for 'hekate battery menu', there are quite a lot of screenshots where the battery drain is around 500mA.You see it draining 500ma in hekate?

The playtime on a full battery should be about 3~7 hours.
If that is the case with your Switch then I would not worry about those Hekate numbers.
If you get far less playtime like 2 hours, then there might be another issue.
well the backlight is low the most time..did you max out backlight settings on option?
