Android 4.4.2 KitKat has been around for quite some time. However, despite previous complaints from users of the first generation of the operating system, it appears problems still persist. As majority of Samsung Galaxy S4 users in the United States shifted to Android 4.4.2 KitKat, many of them complain about battery life and similar problems.

Carriers like Verizon Wireless have started rolling out the Android 4.4.2 KitKat update. The issue now is that as more people started using the update, there are more complaints than ever. While the Android 4.4.2 KitKat update offers a range of new features, as well as improvements, there are also a range of bugs people are worried about. While the overall performance is fine, still, some users prefer they do not have to deal with the bugs.

One problem with the new update is its effect on battery life. As battery life is crucial for every smartphone user, any problems with the battery life of a device can be noticed immediately. According to many Samsung Galaxy S4 users, they have been experiencing shorter battery life since updating to Android 4.4.2 KitKat. A similar issue seems to be plaguing Galaxy Note 3 users as well.

According to a report by Mobile Bloom, one user reported that following his switch to the latest KitKat update, the battery life of the device dropped to 30 per cent. This is within 3 hours time only. That is, 70 per cent of the battery is lost just after 3 hours. This is not normal even for older handsets.

Streaming HD videos and playing games can do this. However, according to the user's complaint, he was only browsing the Internet for 20 minutes. The phone was left idle for the rest of the 3 hours. There are several sources that tested the Galaxy S4's performace and results showed that performance speeds were almost at a standstill for the KitKat update.

Additionally, it took longer for people to switch between applications and browse through the home screen. There were also users who reported that simply pressing the home button took longer than usual. It appeared like the device was on hold and the app manager was lagging.

As for black screen problems, one user suggested a quick fix. That is, open Settings > Lock Screen > Lock Screen Widgets > Clock or Personal Message > Clock. As for battery problems, doing a reset and going back to the previous OS can be a temporary solution until Google issues another patch to solve the problem.
