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