Su Stackoverflow mi è stato detto di venire qui. Da qualche giorno il mio iPhone 5 si riscalda in modo insolito e la batteria si scarica DAVVERO rapidamente, come in 4-5 ore. Ho provato a disattivare tutto il solito sospetto (servizio di localizzazione, dati cellulari, push, ecc.) Ma nessun cambiamento. Ora, guardando i registri degli arresti anomali sul dispositivo, ho trovato un enorme numero di rapporti sugli arresti anomali per il processo di kbd. C'è un registro di crash ogni ~ 30-60 minuti e tutti contengono qualcosa di simile a questo:

Qualche idea su cosa sta causando questo o anche su cosa fa esattamente il processo di kbd? Apprezzerei davvero qualsiasi aiuto poiché questo è davvero un grosso problema e il mio iPhone è diventato praticamente inutilizzabile. Grazie!
EDIT: ho ristretto il problema ai dati danneggiati in iCloud. Non appena disattivo "Documenti e dati" in Impostazioni, gli arresti anomali e lo scaricamento della batteria scompaiono. Ancora non riuscivo a capire come risolverlo.
