I have a specific battery drain question (not the usual)

[o. l. t.]

Due to horrible battery life I’ve reset my s3 Frontier LTE and not added anything to it. Bone stock. Also, turned mobile networks off completely and use no cellular.

I’ve done the typical turn everything off (s-health, watch always on, etc) so nothing is backgrounding.

I can take the watch off charge at 100% and use the watch to scroll through settings for 5 minutes, then check my heart rate one time and it’s at 73%. If i check the weather after that it’s at 65%. This is in 15-20 minutes timeframe.

The Samsung Galaxy app on my iPhone X shows the battery drain is exactly what I’m doing (watch face mostly, and settings).

So I don’t have an uncontrolled background process draining it, the actions I’m doing it are draining it, but it’s dropping like a brick!

My question is if this is how fast this watch typically eats battery if you use it, or if it’s time for me to order a new battery. It will idle for 6 hours only taking 40% or so battery if I don’t touch it at all and the drain seems to be normal to the things being used (hourly heartrate, hourly weather update, nothing else).

Is my battery just weak, or do all these watches eat battery that badly when actually using them (screen on time)?

It depends on the watch, but it can't hurt to have a spare battery (and with a new one, after a week of settling in, you'll know if it's time to dispose of the old one or not).

As always with lithium batteries, though, never let the battery drain below 40%. If you can't charge it at that point, turn it off. (At least the batteries are cheap [$10-$20] and user-accessible. Drain a phone down to near 0 every charge cycle and you'll be paying a lot more to get the battery replaced.)

Thank you. I have another issue. I keep getting this message below. It has only worked 2 times out of 100 tries. I suspect it has to do with the way bluetooth, wifi, and mobile all work together. I’ve reset the watch and deleted and redownloaded the app. It’s not either, it’s a connection setting, but I don’t know what.
