According to Battery University, leaving your phone plugged in when it's fully charged, like you might overnight, is bad for the battery in the long run. Once your smartphone has reached 100 percent charge, it gets 'trickle charges' to keep it at 100 percent while plugged in.
.
Furthermore, at what percentage should I charge my phone?
Do maintain your battery charge level between 40 percent and 80 percent. The ideal charge level for a stable battery is in the upper mid-range. Keeping a battery between 40 percent and 80 percent charged as often as possible will help you get the most out of its lifespan.
Also, is it better to charge phone to 80? A good rule of thumb seems to be to never charge your phone up to more than 80 percent of capacity. Some research shows that after 80 percent, your charger must hold your battery at a constant high voltage to get to 100 percent, and this constant voltage does the most damage.
Similarly, what happens if you tell Siri to charge your phone to 100?
Well, no, probably not, but if you ask Siri to "charge my phone 100 percent" then it automatically starts calling the emergency services, giving you a 5-second window to cancel the call. Asking a kidnapper if you can charge your phone with some weird passphrase is pretty innocuous by comparison.
