How much battery life are you guys getting on your Tab Pro 8.4? I bought mine couple of days back and I felt it's disappointing.

Mine has been fine. But, i use it to read and browse the web. I rarely make it down to 50% each day.

Cheers,

What's your on-screen time in battery stats? Or maybe post a screenshot of your battery usage.

What bugged me was the disappointing battery life when the screen was turned off (not completely powered off of course). Even in airplane mode it would die in a day or two just sitting around. Battery stats showed Android System and OS were killing the battery. I never figured out if there was a setting or something to fix it.

Instead I loaded Cyanogenmod 11 on it a week ago and now it uses only 3% of the battery a day when I'm not using it. I don't miss any of the Samsung extras.

Something must be keeping it awake. My tab has excellent standby battery life.
Doesnt lose more than 5% in a day. I do have the setting to turn wifi off when in sleep mode though (unless plugged in)

Battery life on the whole varies. Video watching through the stock video player drops about 10% an hour. Surfing would depend on your browsing habits. Gaming drains close to 20% an hour. Pretty standard. That along with the excellent stand by time means I get about 2 days of use on a charge.

Every day at work telephony, internet, email, IMO 24hours, 24hours Bluethooth Gear 2 connect. Dinner consists of my tablet battery 55%. For me life is great. My tablet root and frozen Samsung Apps (Bloatware) ... XDA .... Try the Nova launcher from the Play Store to Improve speed. Set it as your default launcher then Disable / Turn Off;
Flipboard, MagazineWidget, S Voice, Samsung Apps, Samsung Apps Widget, SapaMonitor, Screen Saver, World Clock, and (Hancom, Office for Android Share, Hcell, Hshow, Hword, Updater, Viewer Launcher, and Widget) if you do not plan on using it.

We will be adding Quadrant test 24,000 points on the original ROM.

Yes it was using as much battery as watching a movie with the screen on. Something was terribly wrong with it. I think this behavior started after a software update I got from Samsung.

I turned everything off including Wifi and it was still eating the battery while sitting there with the screen off. I have never seen that with any Android device I've ever owned.

But I'm happy with Cyanogenmod. Battery life is outstanding now.

My battery life was mediocre, and then I put cyanogenmod on, and it went to dreadful. With the tablet at 100% and OFF, untouched, it would be 20% down in 10 hours. In contrast, my iPad loses maybe 3% in that time, doing the same thing - tracking email.

I ran a wakelock tracker and noticed that Exchange Services has it awake about half the time. The total time. Like in 10 hours Exchange had it awake (with screen off) more than five hours. Effen ay. Something is seriously screwed up with how Cyanogenmod's Exchange talks to the two Exchange services I use. Switching from Push to "5 minutes" has helped significantly; Exchange is still the worst culprit, but now only by a factor of four rather than a few hundred.

Ideally what I'd like is the new Exchange apks modified to prevent admin and fixed to be less wakelock intensive.
