Battery Drain Fix

iPhone

1. Settings → Battery. Wait 10 sec for it to load.
2. See list of apps + percent of battery used.
3. If ONE app is over 30% — that\'s your culprit. Open it less.
4. If "Activity" is mostly "Background" — turn off Background App Refresh: Settings → General → Background App Refresh → OFF.
5. Settings → Battery → Battery Health → "Maximum Capacity". Under 80%? Time for replacement.

Common drain causes

• Brightness too high — auto-brightness ON saves a lot.
• Old apps running in background — uninstall ones you haven\'t used in months.
• Location services for unnecessary apps — Settings → Privacy & Security → Location → check each app.
• Email "push" — switch to "fetch every 30 min" instead.
• Always-on display — significant drain. Turn off if not essential.
• 5G in poor signal — phone wastes power searching. Switch to LTE if 5G unstable.
• Bluetooth + Wi-Fi + GPS all on when not needed — turn off when not using.
• Apps with lots of notifications — fewer notifications = less wake-up.

When battery is just dying

• Phone is 2-3+ years old.
• Used to last all day, now dies in 4-6 hours.
• Phone shuts off randomly above 20%.
• Capacity reading under 80%.
• Battery replacement is the answer. $69-150 — much cheaper than new phone.
