I rmb not long ago, I posted an issue which is Google Play Service is draining my battery a lot especially when I turn on gps location setting.

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.

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.

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.

11hours?? u turn off all the wifi/3g issit?
anyway sound great...

Is that even possible?

When I first bought it, it was working like this. When the tab is idle (not in use), the highest consuming app is the 'tablet idle' app. Several times I have tried, before sleeping at night and after waking up the next day, the battery remains the same %.

It's just last year the Google Play Service app got updated, which is causing it to consume battery even when the tab is in idle mode. I suspect its because I turn on the location setting and Google Play Service is working all the time to fetch data or searching for location. After updating the Google Play Service manually, my N7 battery life is returning to it's normal self when I first bought it.

Some reads regarding the Google Play Service issues. It has been around since last year November like that.

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.

Guys, I has 2 nexus 7 16GB and 32GB. Wondering why 2 nexus 7 charging time are different? 16GB takes 2 hours and 45 minute but 32GB needs 4 hours. What is your tablet charging time?
