Background App Refresh draining battery

Background App Refresh lets apps update content while closed, which is convenient but adds up in battery use, especially with many apps enabled. Trimming which apps use it is a quick fix.

Time
5–10 minutes

Symptoms

  • Battery drains between uses without much active screen time
  • Many apps show background activity in Battery usage stats
  • Turning on Low Power Mode noticeably slows the drain
  • Battery usage worsened after enabling several new apps

Likely causes

  • CommonMany apps enabled for background refreshEach enabled app periodically wakes up to fetch new content, and the total adds up.
  • CommonA specific app refreshing far more often than neededSocial media, news, and mail apps often refresh aggressively by default.
  • PossibleBackground refresh combined with poor cell signalRefreshing over a weak connection takes longer and uses more power per attempt.
  • Less commonSystem-level indexing or backup tasks running alongside app refreshOccasionally other background maintenance tasks coincide and compound the drain.

What to do

  1. Go to Settings > General > Background App Refresh and review the full list of enabled apps.
  2. Turn off refresh for apps you don't need updated the instant you open them, like games or rarely used tools.
  3. Keep it enabled only for apps like messaging or navigation where instant updates matter.
  4. Check Settings > Battery to see which apps show the highest background usage and prioritize turning those off.
  5. Consider setting Background App Refresh to Wi-Fi Only if it's available, to reduce cellular-related drain.
  6. Test overall battery drain over a day after trimming the list to gauge the improvement.
  7. Turn on Low Power Mode temporarily to compare drain with background refresh effectively minimized.
  8. Revisit the list occasionally as you install new apps, since new installs default to having it on.

When to call a pro

This is a settings adjustment and doesn't require a technician; persistent drain after trimming background refresh may point to a battery health issue instead.
