With the release iPhone iOS 10.2.1, many Apple users assumed that device battery issue will be addressed. However, the battery drain issue was left unfixed by the said update, leaving smartphone users to look forward to iOS 10.3.

Tuesday this week, Apple released the final version of their iOS 10.2.1. The said update was highly anticipated since it was hyped as the potential fix for the persisting 30 percent battery drain issue. However, despite the update, the battery bug was left unfixed.

Instead of offering a remedy to the concern, the update itself actually made the 30 percent bug even worse, according to Forbes. As a result of the failed attempt to fix the bug and worsening user experience, complaints were expressed online. This is not the first time that complaints and criticisms were made public. In retrospect, the Chinese government even criticized Apple for failing to meet the basic needs of consumers.

As an overview of the issue, the 30 percent battery bug causes iPhone devices to shut down upon reaching the 30 percent level of battery power remaining. Such complaint managed to persist despite the effort of the company to extinguish such battery drain issues.

Prior to the release of the said update, users were in the dark about what 10.2.1 may offer. Apple was strict enough not to share any data concerning the update, according to SoC Pedia. Such secrecy is likewise being practiced when it comes to the much anticipated iOS 10.3.

Many iPhone users are quite hopeful that the succeeding update will end the battery drain concern they are currently experiencing. However, the same website hinted that iOS 10.3 is an update focused more on the introduction of a new feature, rather than bug fixes.

Furthermore, said testing of the anticipated another iOS update will also last for around 4-6 weeks. Thus, suggesting a longer wait time for Apple users to undergo until the arrival of  iOS 10.3.
