| Recurring |
one_organization, multiple_organization |
(a) The software failure incident related to battery drain and connectivity issues with the iPhone 4S occurred again within the same organization, Apple. The iOS 6.1 update was intended to address cellular connectivity issues but ended up causing battery drain problems for many iPhone 4S users [17086].
(b) The software failure incident related to battery drain and connectivity issues with the iPhone 4S also affected multiple organizations. For example, U.K. carrier Vodafone warned its iPhone 4S-owning subscribers not to update to iOS 6.1 due to issues with connecting to 3G networks [17086]. |
| Phase (Design/Operation) |
design, operation |
(a) The software failure incident related to the design phase can be seen in the article where an iOS update (iOS 6.1.1) was specifically designed to address cellular connectivity issues in the iPhone 4S. However, instead of resolving the issue, the update led to persistent battery drain issues, overheating, and unusually high battery loss for many users [17086].
(b) The software failure incident related to the operation phase is evident in the article where users who updated their iPhone 4S to iOS 6.1.1 experienced issues with connecting to 3G networks, leading to warnings from carriers like Vodafone not to update to the new software version. Additionally, some users found that deleting and re-adding a linked Microsoft Exchange account fixed the battery drain issue, indicating operational challenges with certain account configurations [17086]. |
| Boundary (Internal/External) |
within_system, outside_system |
(a) within_system: The software failure incident related to the iOS update causing battery drain and overheating in iPhone 4S devices is primarily within the system. Users reported issues with the battery life and overheating after updating to iOS 6.1 and iOS 6.1.1, indicating that the problem originated from within the software update itself [17086].
(b) outside_system: The software failure incident also involved factors originating from outside the system. For example, U.K. carrier Vodafone warned its iPhone 4S-owning subscribers not to update to iOS 6.1 due to issues with connecting to 3G networks, indicating that external factors such as network compatibility played a role in the failure [17086]. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident occurring due to non-human actions:
- The iOS 6.1 update for iPhone 4S was intended to address cellular connectivity issues but ended up causing battery drain problems, overheating, and unusually high battery loss for many users [17086].
- A new security bug in iOS 6.1 allowed anyone to bypass the lockscreen, indicating a vulnerability introduced without human participation [17086].
(b) The software failure incident occurring due to human actions:
- Some iPhone 4S owners experienced battery drain issues after updating to iOS 6.1 due to having a linked Microsoft Exchange account to their mail and calendar. Deleting and re-adding the account fixed the problem, suggesting a human action (setting up the Exchange account) contributed to the failure [17086]. |
| Dimension (Hardware/Software) |
hardware, software |
(a) The software failure incident related to hardware:
- The iOS update, iOS 6.1.1, was intended to address cellular connectivity issues in the iPhone 4S, but instead, it led to persistent battery drain issues and overheating for many users [17086].
- Some iPhone 4S owners experienced issues with connecting to 3G networks after updating to iOS 6.1, prompting U.K. carrier Vodafone to warn subscribers not to update [17086].
(b) The software failure incident related to software:
- iOS 6.1 update introduced a new security bug that allowed anyone to bypass the lockscreen, indicating a software vulnerability in the system [17086]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident related to the iOS update for iPhone 4S can be categorized as non-malicious. The update, iOS 6.1.1, was intended to address cellular connectivity issues and battery drain problems experienced by users [17086]. Additionally, the incident involved a security bug that allowed anyone to bypass the lockscreen, which Apple acknowledged and promised to fix in a future software update [17086].
(b) The software failure incident was not malicious but rather a result of unintended consequences and technical issues in the update process. |
| Intent (Poor/Accidental Decisions) |
accidental_decisions |
(a) The intent of the software failure incident related to poor_decisions:
- The software failure incident involving the iOS 6.1.1 update for iPhone 4S was intended to address cellular connectivity issues but ended up causing battery drain problems and overheating for many users [17086].
- Apple released the iOS 6.1.1 update to resolve issues with cellular performance and reliability for the iPhone 4S, but it led to complaints of persistent battery drain issues and overheating among users [17086].
- Despite the intention to fix the connectivity problems, the update resulted in widespread complaints about battery issues, with some users reporting a significant decrease in battery lifespan and overheating after updating to iOS 6.1.1 [17086].
(b) The intent of the software failure incident related to accidental_decisions:
- The software failure incident involving the iOS 6.1.1 update for iPhone 4S was not intended to cause battery drain problems and overheating for users but rather to address cellular connectivity issues [17086].
- Users who updated to iOS 6.1.1 experienced unintended consequences such as overheating and unusually high battery loss, indicating that the issues were accidental rather than deliberate decisions by Apple [17086].
- The update was meant to improve the performance and reliability of the iPhone 4S, but it inadvertently introduced battery drain issues and overheating problems, suggesting that the negative outcomes were accidental rather than intentional [17086]. |
| Capability (Incompetence/Accidental) |
development_incompetence, accidental |
(a) The software failure incident related to development incompetence can be seen in the article where an iOS update, iOS 6.1.1, was released specifically to address cellular connectivity issues in the iPhone 4S. However, instead of resolving the issue, the update led to persistent battery drain problems for many users [17086].
(b) The software failure incident related to accidental factors can be observed in the same article where iOS 6.1 was found to have a security bug that allowed anyone to bypass the lockscreen, indicating a vulnerability that was accidentally introduced into the software [17086]. |
| Duration |
temporary |
(a) The software failure incident described in the article seems to be temporary rather than permanent. The article discusses how the iOS 6.1.1 update for iPhone 4S was intended to address cellular connectivity issues but ended up causing battery drain problems for many users. Users reported overheating, unusually high battery loss, and issues with connecting to 3G networks after the update. Apple acknowledged the issues and provided workarounds while working with Microsoft to fix the problems. Additionally, a security bug that allowed bypassing the lockscreen was also identified in iOS 6.1, indicating temporary failures that were introduced by specific circumstances such as the software update. The company promised to deliver fixes in future software updates, suggesting that the failures were not permanent [17086]. |
| Behaviour |
omission, value, other |
(a) crash: The software failure incident mentioned in the articles does not specifically describe a crash where the system loses state and does not perform any of its intended functions.
(b) omission: The software failure incident can be related to omission as the iOS update (iOS 6.1.1) intended to address cellular connectivity issues in the iPhone 4S ended up causing battery drain issues for many users [17086].
(c) timing: The software failure incident does not relate to timing issues where the system performs its intended functions correctly but too late or too early.
(d) value: The software failure incident can be related to value as the iOS update caused the system to perform its intended functions incorrectly by draining the battery and causing overheating issues for iPhone 4S users [17086].
(e) byzantine: The software failure incident does not exhibit behaviors of a byzantine failure where the system behaves erroneously with inconsistent responses and interactions.
(f) other: The other behavior exhibited in this software failure incident is the introduction of a new security bug that allows anyone to bypass the lockscreen in iOS 6.1, which is a critical security flaw [17086]. |
