To turn off safe mode on a Samsung Galaxy Ace just turn off the phone and take out the battery. Replace the battery and turn the phone back on and it should reset it to where it is not on safe mode.

That charge time is usually called the "core charge" when you get a new device the battery is dead or has been on a sleep mode. Anyway that time is to give it a corecharge, meaning more battery life in the long term.
You don't tell us if this is right after you charge it or after several hours. Go into settings and check to see if you have airplane mode on, hotspot on, Bluetooth on, and check your battery settings. You can turn on low power mode in this setting and here you will find battery percentage. Try a another lightening charger too.
Both "safe mode" and "safe mode with command prompt" runs with essential drivers that is necessary for the computer to function. Difference is, Safe mode runs with "Explorer.exe" shell and "safe mode with Cmd prompt" runs with "cmd.exe".
