By Playing for Frags
Frags are one of the fastest ways to gain a lot of experience points in CODM.
So yeah, having an aggressive play style is the way to go, truly. It maximizes the number of experience points you can gain in each COD Mobile match compared to playing passively, such as camping in a spot or hiding in spawn areas.
Through Scoring Assist Kills
If you're having trouble getting frags, don't worry, since there are still a variety of ways to gain experience points in-game.
Assists can be obtained in various methods, including frag assists, score streak assists such as when deploying the UAV, shooting down score streaks with your FHJ, and simply accomplishing the objective in game modes.
However, completing a large number of objective challenges in the games will result in a substantially shorter game.
By Getting a Win Streak
The fact that winning matches rewards players with more experience points than losing games cannot be contested. It is evident that winning every match is not a simple feat, especially when competing against high-level players, however, it is not impossible.
Invite friends to assist you if you want to increase your chances of winning. You have more chances to defeat the enemy team and achieve victory by cooperating with your teammates in getting more frags, fewer fatalities, and completing the objectives.
By Joining Clans
Playing with your clan mates allows you to earn extra XP after the match, which accelerates your level progression. You can join an existing big clan or create a new one by clicking the Clan button just below the lobby. And who knows, maybe someone from a clan that you join to will be kind enough to gift a Battle Pass in CODM to you?
In addition, as you complete challenges in the clan, you can earn clan rewards, which you can use to purchase weapon skins, character skins, and other game stuff.
However, if your avatar is goofy, you might want to change your CoD Mobile profile pic to something serious, as then you might have trouble joining any clan.
By Completing In-Game Challenges
Every season, we are presented with new challenges in the form of limited-time events such as Featured Events, Seasonal Events, Gun Challenges, and Clan Events. Players are rewarded with skins, coupons, in-game currencies such as COD Points, and, most importantly, experience points for accomplishing these tasks.
Through XP Bonuses
COD Mobile occasionally provides a limited-time double XP event for players. These double XP events multiply the experience points you get in each match by two, making things much faster.
Through XP Bonuses from Weapon Skins
With several skins to choose from in COD Mobile, some weapon skins can provide players with more XP because of the 10% XP boost after finishing the match, as opposed to utilizing the default skin.
