I think the only damage you can do is unplugging it before it is fully charged
Absolutely. The SIM carries the service information for your phone while the battery only provides power to the phone.
This can be due to the charger being faulty or not being official, 3rd party chargers often don't provide the recommended power and so take longer to charge the phone. It can also be due to you using the phone while it's on charge, as this can still drain the battery.
Yes, the outlet will be used to power the phone. Try it.
If the battery is charged, there may be a bad contact, or a shorted switch in the handset.Checking phone battery and power connections:1. Open the battery pack2. Remove battery (do not cross terminals)3. Wash battery sensors with a q-tip using rubbing alcohol4. Let sensors dry at least 5 minutes5. Replace battery6. If still no power, try a different battery or have phone serviced
AS SOON AS you get your phone wet remove the battery and battery cover, and leave them off for at LEAST 3 days while you leave the phone fully opened (if you have a clamshell, flip or slider phone) and propped upright such that any water or droplets trapped inside will hopefully be able to drain out and/or evaporate. The objective is to prevent the phone's screen(s), keypad and circuitry from being short-circuited any further than they already have been while you let it dry out as thoroughly as you possibly can for as long as you possibly can. THEN re-insert the battery and try powering up the phone. If no power at all, the battery may have been permanently damaged so you may want to take it out IMMEDIATELY and replace it with a new one. If the phone then still doesn't work it's shot.
The battery has a temperature sensor. If it was left unplugged, the battery light will still be on
Yes
not at all but if you dont use your car for a while and charge you phone inside its maybe possible but after a month or so if your battery is worn
No. A cordless phone battery does not have anywhere near enough current to harm you.
If you're asking about the car battery, the practical answer is "No."; the drain on the car battery would be negligible. The current used would be significantly less than 1 of your interior dome lights while the phone is charging, and once the phone is fully charged it (and the charger) would consume even less. If you're asking about the phone's battery, the only effect would be a charged battery. The process does not promote an unhealthy state for either battery in any practical or realistic scenario.
yes
