Hairline cracks

Since the iPhone 3G's public release, users have reported that there had been hairline cracks, especially on the white models.[17]

[edit]Battery life

After the release of the iPhone 3G, many complaints were about battery life. This is also reflected by a J.D. Power and Associates custom satisfaction survey, which gave the “battery aspects” of the device its lowest rating of 2 out of 5 stars.

[edit]iOS performance issues

iOS 4, which was still compatible with the iPhone 3G, was released on June 21, 2010. Since its release, many iPhone 3G owners on iOS 4 have reported that their phones are performing much slower than they had prior to the update.[18][19] Video comparisons of the performance differences have been posted.[20] One theory claims that the problem stems from a bug in the Spotlight Searchfeature.[21] Another claim, is that the 3G has insufficient RAM memory to cope with the demands of the new iOS 4 operating system: only 128 MB, versus the 512 MB of RAM in the iPhone 4 for which iOS 4 was designed.[22][23]

An article in the Wall Street Journal's Digits column on July 28, 2010 drew attention to the situation, reporting that iPhone 3G phones updating to iOS 4 responded slowly, had diminished battery life, and became excessively hot.[24]

During a media event on September 1, 2010, Apple announced that iOS 4.1 would be released on September 8, 2010, claiming to fix issues with performance on the iPhone 3G, along with fixes forBluetooth and proximity sensor issues and other updates. The update did improve the speeds on the iPhone 3G, however, the speeds still remain well below acceptable levels. iOS 4.2.1 further fixed performance issues on the iPhone 3G.
