I've been experiencing disappointing battery life since the android 4.3 update last month on my non-LTE t-mo galaxy s3. I know there's been a lot of discussion and advice by t-mo reps on various forums, but it simply isn't accurate. The party line is "something you installed on your phone is causing increased battery drain after the 4.3 update." However, my partner and I have two identical T-mo galaxy S3's. We have entirely different sets of apps installed on our phones. As soon as we installed the 4.3 update, both of our phones started to drain rapidly faster than before the update. On 4.2 our phones would last to 50% by the end of the day (~8pm) with light to moderate use. Now they're at ~20% by the end of the day, and I can see my battery levels drop faster just while using the phone. This is totally unacceptable. I've downloaded battery monitoring apps, and no apps I've installed are draining the battery, it's the system and kernel that take up most of the cpu. People are saying it's the touchwiz additions that are causing the system to use up more cpu cycles. I refuse to do a factory reset because there's so many reports of this not doing anything. There's clearly a bug in the 4.3 update for the SG3, unless it's touchwiz as everyone seems to indicate. How can I check to see if something is causing too many lock wakes?
