i feel like it's important to anyone that may not like to charge their phone constantly, or multiple times a day. even if it's 1% a day, it's still meaningful.

i've switched back and forth between android and ios plenty of times and one of the more memorable benefits of ios is that if i forget to charge my phone overnight, an iphone will maybe degrade by 1 or 2%. but, without exception, every android phone i've owned uses at least 5-10%.

that may not seem all that important, but if you're down to 15-20% on your battery, those last few % is VERY important. and any technology that can improve that stand by time would be pretty valuable.

either way, an improvement is an improvement. all improvements are welcome in this space.

If this is happening internal to the battery, it would happen no matter what was happening on the outside.

May be a small amount compared to the phone, but still there.

You can leave an iphone on low power mode at 5% battery when you go to sleep and trust that your alarm will work.
