Satyabhama was the third wife of Lord Krishna. People think that she is the second wife because Rukmini and Satyabhama are worshipped with Lord Krishna. It is incorrect. Satyabhama was the second prominent wife of Lord Krishna. The second wife of Lord Krishna was Jambavati who married him and after that when Lord Krishna safely handed the Syamantaka jewel to Satyabhama's father he asked Lord Krishna to marry Satyabhama. Satyabhama was the third wife of Lord Krishna but she was the second prominent wife(status wise).
Satyabhama was the incarnation of Bhudevi (who is Dhanyalakshmi).
Satyabhama was the beloved of Lord Krishna and he fulfilled all her wishes.
Satyabhama's father was the Yadava Satrajit.
Satyabhama slayed the demon Narakasura and not Lord Krishna. Narakasura could be slayed by Bhudevi his mother and not any other person. That's why Bhudevi incarnated as Satyabhama to slay him.
Satyabhama had demanded for the celestial Parijata tree from Lord Indra's palace. She wanted to teach one lesson to Queen Shachi the wife of Lord Indra who didn't come to welcome her when she and Lord Krishna returned the celestial earrings of Mother Aditi after Narakasura was slayed.
Satyabhama was joyful because she had the Parijata tree to herself but because Rukmini wished for the flowers Lord Krishna planted the tree in such a way that the flowers fell into Rukmini's palace courtyard and the tree remained to Satyabhama. One folktale says that Satyabhama complained to Lord Krishna about the flowers that they fell into Rukmini's courtyard. Then Lord Krishna said that he would fulfill her wish but whenever the flowers of the tree fell into her courtyard it would mean that Lord Krishna is with his beloved Rukmini. Therefore Satyabhama couldn't complain now. This is a folktale. But the truth is that the flowers of the tree fell into Rukmini's courtyard and the Parijata tree remained to Satyabhama.
Satyabhama prided herself sometimes and she wanted Lord Krishna to listen to her and be with her forever. But the Tulabharam incident surprised her and she learnt one lesson from it. Her jewels and wealth and money couldn't please Lord Krishna but Rukmini's Tulsi leaf which she placed on the Tula won Lord Krishna's love . Satyabhama understands that Lord Krishna likes selfless service and not riches or any of the jewels. Therefore Rukmini's selflessness was depicted here.
Satyabhama loved Lord Krishna and because of that she wanted him to be with her and fulfill her wishes. She was also loyal to Lord Krishna. She was beautiful and devoted wife.
Satyabhama had two sisters Vratini and Prasvapini both who were married to Lord Krishna which is mentioned within the Harivamsa. The three sisters were married to Lord Krishna but we know Satyabhama. The two sisters are not included within the principal wives of Lord Krishna.

“He also had three daughters well-known in all the quarters, namely lady satyabhama, a magnificent lady - both in beauty and wealth; lady Vratini of firm vows is the second; lady prasvApini is the third... Satrajit married them all with Krishna.”
-Harivamsa.
Satyabhama and Lord Krishna had 10 sons - Bhanu, Swabhanu, Subhanu, Bhanumaan, Prabhanu, Atibhanu, Pratibhanu, Shribhanu, Bruhadbhanu, and Chandrabhanu.
The Vayu Purana mentions that the Pandava Yudhisthira and his wife Draupadi's daughter Suthanu married Lord Krishna and Satyabhama's son Swarabhanu.
Satyabhama was the best friend of Draupadi and she praises Draupadi for her dedication towards her five husbands within the Draupadi- Satyabhama Samvada Parva of the Mahabharata.
After Lord Krishna leaves for Vaikuntha some robbers resist Arjun who is unable to win even when he has celestial weapons. The Junior wives of Lord Krishna and taken by the robbers and the principal wives like Rukmini and Jambavati immolate themselves. Satyabhama and the other wives reach Kalpa within the Himalayas where she meditates and spends her life there within meditation and chanted the name of Lord Krishna.
Satyabhama was also dear to Lord Krishna like he loved his chief wife Rukmini.
