A phone stuck in a boot loop is usually caused by a software problem after an update or a faulty app, a weak battery, or a mainboard fault. Software issues can sometimes be fixed with safe mode or a reset, but battery and mainboard faults need a technician. If the data on the phone matters, don’t jump straight to a factory reset.

What causes a boot loop?

  • A failed or interrupted system update, for example when the battery dies mid-update.
  • A faulty app that runs automatically at start-up.
  • Full storage, so the system can’t run normally.
  • A weak or swollen battery that cuts out when the phone needs a burst of power to start.
  • A mainboard fault, for example after a drop, water exposure or frequent overheating.

Safe steps to try

  1. Charge for at least 30 minutes with a suitable charger, then try again.
  2. Boot into safe mode (the method varies by brand). If it works there, remove the most recently installed apps.
  3. Remove the memory card and accessories, then try again.
  4. Factory reset only as a last resort, and only if your data is backed up or not important.

When should it go to a technician?

  • The phone still loops after the steps above.
  • The battery looks swollen or the phone gets very hot. Stop charging it.
  • The loop started after a drop or water exposure.
  • The data inside matters and isn’t backed up.
