It is bad to leave IPhone 6S in low power mode forever?

Came across this thread. I've used low power mode since introduced. Has been great for my battery life. When I forgets to turn it on, definitely notice the decline in battery life. Without low power mode, by evening battery is dead. With lower power mode, by the end of the day I'm still at 30-50%.

What I've never understood in why Apple can't provide the option to leave low power mode always on? As a long time user, there is nothing I use the phone for that is affected by low power. My Alerts still come through, no detrimental affects. The biggest frustration I have is after every charge, I must remember to turn low power back on.

I couldn't agree more! I use my phone at work all day, but primarily for listening to podcasts while I'm driving. I am usually able to get to a charger (in my car) but if I get over 80% low power mode turns off. Then when I get to my next location I drain my battery just having it on.

Even just having an option to set the battery or low power button to a quick menu (like my android does) would be very helpful. Bottom line: we need *options*.

Low Power Mode reduces or turns off Email fetch, Hey Siri, Background app refresh, Automatic downloads, Wi-Fi associations, and some visual effects. If you can live without having those features available on the phone, you can keep it on low power mode. But after you charge your iPhone to 80% or higher, Low Power Mode automatically turns off, so you'll have to turn it back on again.

About iPhone Low Power Mode - Apple Support

Common sense should prevail here. It makes no sense for the device to support such a feature if it's going to do itself harm.

Low power mode works identical in 5s and 6s. When you charge over 80% iOS automatically switch off low power mode. Low power mode reduce frequency of CPU to 40% lower, so it should be even healthier for your device.
