For those who are experiencing short battery life and under the battery app, you see that the Google Play Service app is sucking a lot of juice from your battery. I found a solution to it. You need to update the new Google Play Service 4.1 version. I don't know why my N7 wasn't pushed into automatically updating this Google Play Service app. This is weird. After Google-ing a lot, I found out that many Android devices running on Google Play Service 4.0 suffers from battery drain from this app. And recently, androidpolice's website has a news on a new Google Play Service is updated, which is the 4.1 version. Perhaps most important to non-developers, Google appears to have "improved" battery life for users who have Location Reporting enabled. Readers may recall this was an issue with previous Play Services releases. source > http://www.androidpolice.com/2014/01/09/go...eview-and-more/ related issue > http://www.androidpolice.com/2013/11/19/it...tery-hog-today/ I've just updated my Google Play Service to the latest version by installing the apk. Let's hope it fixes the problem of Google Play Service being a battery hog. » Click to show Spoiler - click again to hide... « QUOTE(briantwj @ Jan 12 2014, 01:09 PM) Update: Fully charged my tablet yday before I sleep. Unplug at 2am this morning. After 11 hours (today 1pm), the battery is still at 100% If seems like the Google Play Service is really at fault previously. » Click to show Spoiler - click again to hide... « QUOTE(briantwj @ Jan 12 2014, 02:03 PM) Some reads regarding the Google Play Service issues. It has been around since last year November like that. http://androidcommunity.com/play-services-...s-why-20131120/ We tested this out with our Nexus 4, just to be sure. We had all cellular connectivity and WiFi off. We also disabled location sharing and background app refreshing, basically making our device a dumb brick instead of a smartphone. The result? Nearly 10% battery drain in two hours. In that mode, we routinely get through a day with a 4% loss in battery. I think Google was testing something. More spying from them I would say, maybe trying to fetch more information from android device to learn the users' pattern and recommend apps in playstore. Just an example. Just try Google-ing 'Google Play Service battery drain'. U'll find plenty of complains from users about it. For those who are suffering from battery drain when u are not using ur tab. And the culprit is 'Google Play Service' app. Just thot of sharing this to u guys. This post has been edited by briantwj: Jan 12 2014, 02:26 PM

I use the Wugfresh Nexus Root Kit, downloaded the 4.4.2 image from here https://developers.google.com/android/nexus...s#nakasigkot49h Then I just follow the guide, I clicked Flash Stock + Unroot. Chose the 4.4.2 image downloaded from Google's page. It went well. The command prompt was running. Then it succeed, too fast. But when i look at my N7, i press d power key which is showing 'start'. Then my laptop keep got d usb plugging n unplugging sound. Now my N7 is stucked with the only options being, start, restart bootloader,recovery mode and power off. I tried all option, but cant work. Only can power off. I tried to choose Flash Stock + Unroot again. but this time, the process is interrupted, saying ADB device not found...wad to do now!! I've tried Googling but to no avail. I can only power off, and restart bootloader. I'm stuck between power off, bootloader. The 'Start' and 'Recovery mode' option do not bring any effect. Am I softbricked? I'm using Nexus 7 2012. But the tered gone cold dy, so trying to ask help from this tered.
