Battery life

[substring]

Samsung's spec claims the battery can last for 10 hours. But I cannot get my tab to last that long and I end up to have to charge it during the day. Now, I don't stream video or music. All I use the tab is checking email, get on Google+ and Twitter, and visit web sites. I cannot imagine how in the world my battery gets drained that quickly.

Also, last night before I went to bed, I knew my tab had at least 80% of battery, and then I switched it to Airplane mode. But this morning, my tab prompted me that the battery is critically low and I have to charge it. How that happened?!?!

I look into the Settings-->Application to look for clue on what's using up my battery, but I could not find anything suspicious.

Does anyone has issue with the battery life? Can anyone please shed some light on this?

Thanks!

That's odd. If I switch into airplane mode my tab could sit for days and only lose a few percent of battery. If I leave wifi on all day, I can easily make the full day using the tab more heavily at night before going to bed. I have never run out of battery during the day, but I don't use it heavily.

I talked to Samsung Tech Support but she has no idea what's causing this problem. She went through the standard list like GPS, bluetooth, screen brightness and live wallpaper. But I told her that I put it in airplane mode and went to sleep. So screen brightness and live wallpaper are irrelevant. And I double-checked and confirmed that both GPS and bluetooth are off.

I will test it again at night and see if I have the same result.

Do you have the LTE Verizon version? If so, probably the 4g. If not, you may have a defective battery. I have the wifi version and I never have to put it in airplane mode. Battery lasts about 8-10 hours even with video and gameplay.

I have WIFI only version. Set the WIFI disconnect policy to "NEVER WHEN PLUGGED IN". Battery life increased drasticly.

I can watch a whole movie and just lose about 10-20% if that.

I've been getting 12 plus hours with constant use daily with wifi version.

Just want to let everyone knows that my battery is working fine for the last few days. I went to Setting --> Manage Application to look for clues, and I had found that the CNN for Android Tablet app was running, even though I was not using it. I closed it manually, and I have not been using it since then for testing purpose. I have switched to using FoxNews and AP News instead. And sure thing, I no longer have any unusual battery drain. So the problem is on the app.

My battery life has been quite impressive until the TW update. The MediaHub is a battery killer. I cannot figure out how to uninstall it. I may have to root.
