Other Secondary iphone charging

[Sebastian79]

I have an iphone XS with a 3rd sim card which I leave at home. I need it to stay turned on and receive SMS messages, which I only check at the end of each day. My question is should I keep it on charge all the time? Would it affect battery life?

Thanks!

If you put on optimised charging it should not affect your battery health. If you just plug it in and it’s constantly on charge, your battery health will degrade.

So If I keep it plugged in but with optimized battery charging on, battery health will not degrade?

It won't degrade as much as charging it solidly with no power management features. It'll still obviously degrade as it'll be charged as and when it is required to charge, there is no way around that. If you don't want your battery to degrade, don't charge it.

I would personally just leave it uncharged and on standby because your phone should last many days on standby without requiring a recharge.

What do you mean by 'stand-by'? Do you mean Low power mode?

Standby refers to the time your phone is powered on but not actively being used.

Yes, your battery will degrade if you leave it plugged in, even if ‘optimized charging’ can hold it at 80% (which I highly doubt it can). Keep it <50% to reduce aging/capacity loss with a few options:

If you have wifi, you can use a shortcut automation paired with a $15 HomeKit compatible smartplug to automatically cycle 50-20. The Chargie.org USB dongle can do the same via Bluetooth (and may be easier to program).

Could also use a dumb light timer to charge a fixed #mins per day or twice a day, attempting to balance the standby drain…. But that will eventually go out of whack and require adjustment.

Or just simply apply the convention approach - treat the batt as disposable item and pay for the Apple battery swap when the time comes.
