The iPhone 5 has had a considerable number of problems during its days - from inaccurate Apple maps to battery drains. Could the iPhone 5S be having problems of its own too?

Users of the iPhone 5 have complained of faulty and inaccurate Apple maps that came with the iOS 6 upgrade. Complainants claimed that Apple maps incorrectly directed them to locations, provided buggy satellite images, and provided out-of-date information on several establishments.

Apple was quick to address the issue, and the company's CEO even issued a formal apology to iPhone 5 users. "While we're improving Maps, you can try alternatives by downloading map apps from the App Store like Bing, MapQuest and Waze, or use Google or Nokia maps by going to their websites and creating an icon on your home screen to their web app," Tim Cook's apology letter read.

Other users of the iPhone 5 also reported problems with the handset's battery which reportedly drainsquickly and excessively. Problems with the iPhone 5 overheating were also reported. According to Digital Trends, problems with overheating and excessive battery drain were linked to a problem with Microsoft Exchange 2010. Proposed solutions and temporary fixes include switching to manual fetching of new data for the application and performing a hard reset on the iPhone 5.

The black models of the iPhone 5 also incurred scratches and chips fresh from the box, according to Wired. White models suffered from white light streaking - which was also a problem encountered for the iPhone 4s white models. Screen glitches, purple glare, rattling noise from the inside and date and time bug problems were also reported.

The iPhone 5s boasts of its fingerprint sensor/scanner as one of the highlights for the device. Although most fans are thrilled, some are also quite wary of the new feature. Users planning to switch to the iPhone 5s are worried of potential hacking and have several concerns when it comes to privacy.

U.S. News also mentioned two privacy concerns apart from potential hacking of the fingerprint data. Citing an independent technology researcher and consultant, unlocking through a fingerprint scanner might "make it easier for someone to compel users to unlock their phones." A technologist from the New American Foundation's Open Technology Institute also said that users' fingerprints are also at risk of being duplicated for phone access.

Apple has already explained that the fingerprint data will be stored in the Secure Enclave. Data will not be accessible by iCloud or other applications.
