[myTouch 4G Q&A, Help & Troubleshooting] Quatrix:
Since around Thanksgiving, my battery has been draining in about 36 hours when it normally lasts 3 - 4 days. What I gathered from BetterBatteryStats is that the Wi-Fi is keeping the phone from sleeping about half the time. I used a different app to monitor data usage, and Wi-Fi traffic was low. My guess is that an app is frequently accessing the Wi-Fi without sending much (or any) data. Is there a way to find the culprit without uninstalling apps one by one?
