Call of Duty: Mobile is rated 18+, and that is the useful fact

Apple rates Call of Duty: Mobile 18+, the highest age rating among the sixteen games in our directory. It also has live voice chat. Those are the first two details to check if someone younger is asking to play.

What the rating is actually about

It reflects realistic violence, in a military shooter, presented without stylisation. That is a straightforward content judgement and reasonable people land in different places on it.

The part the rating does not cover is the part that more often causes problems: this is a live multiplayer game with voice chat, and an age rating says nothing about who your child is talking to. That is a settings decision, and it is much easier made before the first session than after.

It is a demanding install

• Roughly 2.8 GB to download, and live shooters update often and substantially.
• Requires iOS 15 or later.
• Competitive shooters are among the most battery-hungry things a phone does — continuous rendering, constant network traffic, and no idle moments.

If sessions end with a hot phone and a flat battery, why games drain your battery explains what is actually consuming it.

Matches have a fixed length, and you are in them

Multiplayer shooters do not pause. Leaving mid-match affects other people and usually carries a penalty, so the real unit of commitment is one match rather than one session. That makes it a poor fit for five spare minutes, whatever the load times suggest.

Who it suits

Adults who want a competitive shooter on a phone and have the storage and battery headroom for it. For a household with younger players, the rating and the voice chat are the two conversations worth having first.
