I left my samsung phone charging overnight for 7 hours overnight will it damage my battery?

It can and that goes for anything with batteries that can be charged. Chargeable batteries and such have a zero point. A zero point is basically like a stopper in a sink. Overcharging starts to wear away at that zero point. So your device takes longer to charge and holds a charge for a shorter and shorter. Tell you reach a point where charging your device is like trying to fill a sink with no stopper in it.

With chargeable devices trying to keep your device 100% charged all the time and not letting it completely run dry at least once a month does start wearing away at your batteries zero point. It does not matter if the battery is a separate part or built into the device. So even something like a chargeable electric razor has a zero point that can wear away.

No. Charging systems have a logic not to overcharge. I often keep my phone connected over night.

No. Batteries have overload protection, the only way to damage a Battery is to discharged it below certain voltage level.

Yes, but it's a very small amount. Batteries take damage every time you charge them. If you do this every night you might do 5 years of regular damage in maybe 4 years.

Lithium-ion batteries, which is the kind Samsung uses prefers to stay between 40-60% charged. If you're really worried about your battery lasting for several years you should try to stick between 20-80%, only fully charging in the last 6 months.

I dont really full it now I unplug it at 90% is it still bad? Then charge it at 15%

I doubt it but when in doubt talk to your phone maker or provider 🙂👍

Yeah. Do not charge it overnight every time. Once or twice would be okay.
