You'll get an on-screen alert with sound when you plug in or unplug, when the battery drops to 20%, and at 80% so you can unplug. Alerts work while Tuvvo is open on any page. A website can't stop charging by itself, so use your phone's own charging limit (tip below) to stop it at 80% for you.
- Keeping the battery between 20% and 80% helps it last more years.
- Most phones can stop charging at 80% for you. Look for "Charging optimisation" or "Battery protection" in Settings, or "Charging" on iPhone.
- To see battery health: on iPhone go to Settings, Battery, Battery Health. On Android, try Settings, Battery, or dial *#*#4636#*#* on some phones.
Common questions
- Why stop charging at 80%?
- Lithium batteries wear faster when kept full and warm. Staying between 20% and 80% most days can add years of good battery life.
- How do I check battery health?
- On iPhone: Settings, Battery, Battery Health. On Android: Settings, Battery, or Battery and device care on Samsung. Below 80% health, a battery replacement is usually worth it.
- Why doesn't this work on iPhone?
- Safari does not share battery details with websites. The tips on this page still apply, and iPhone has its own 80% limit in Settings, Battery, Charging.
- Is fast charging bad for the battery?
- Not much on its own. Heat is what hurts, so avoid charging under a pillow or while gaming.
