Hey guys, so before, when I was on 4.3, overnight I would only lose about 2 to 4 percent battery life. I would charge my Nexus 7 until 100 percent during the evening. Then I'd unplug it but not use it. I'd fall asleep and wake up about 8 hours later and the battery will be about 98 percent. This kind of battery life is outstanding and I would love for my Nexus 7 to reach this benchmark again. Last evening , I fully charged my nexus 7 (now on 4.4) and unplugged it and didn't use it. When I woke up 8 hours later, the battery was at 82 percent. I was surprised (this is the first time I noticed it. (I've been busy because I just took up driving, and it's Thanksgiving break... Plus I just received the OTA update on Thursday). Anyways I went to settings and tapped on battery, and noticed that Android OS was the culprit. I saw a forum where people stated that a factory reset would take care of the issue. I do not want to lose my app data and go through downloading and installing every single app again. Are there any troubleshooting steps I could go through to resolve my battery issue or should I just reset my Nexus 7? Thank you guys.
Its probably the wifi wakelock that a lot of us have been having on Kit Kat. My router or devices on my network are waking up my tablet and phone roughly a few hundred times an hour, not allowing the devices to sleep at all. Use the beta Better Battery Stats to see what your wakelock is.
