    I expected great battery life per Samsung hype and online reviews. But seems to drain quickly. I'm an experienced tablet user so I know the various power saving routines. Are others surprised by lousy battery times? I can literally watch drop the percentage icon next to the battery icon.

    Can you post a screenshot of battery useage? We may be able to assist further after seeing that.

    I recently had an issue with my Sprint Galaxy Tab 3 7.0. I turned out that a defective SD card was the source of the excessive battery drain.

    Very interesting...makes sense though.

    What tipped you off to the SD card being the battery drain?

    I timed it and I lost about 10 percent in one hour. Does that seem normal for just surfing using chrome?

    I had seen other threads in the Galaxy S3 forums regarding battery issues due to an SD card. My Galaxy Tab had never had issues with battery life until I added the SD card. As soon as I removed the card the issues went away.

    I have a SanDisk 32GB card and I am very pleased with the battery life. This is with moderate to heavy usage (surfing, downloading, games, Facebook, etc)

    My Tab 3 8.0 was idle for 19 hours and comsumed 20% of my battery power. Is this excessive or is that just normal?

    Depends on what you have running in the background. If you have apps like Facebook pushing notifications or widgets that update every hour or two, you'll naturally lose more battery even when idle.

    I have found exactly the same on my TAB3 10.1 using a SanDisk 32gb card, with the card in my battery drains in les than a day with moderate usage, without the card it lasts for at least 3 days.
    Has anybody found a card which does not put a drain on ?. I thought a memory card only uses power when it is accesed , but these seem to be powered up at all times.

    I have not charged my Tab 3.8 tablet since yesterday and when turned off last night it had 92% battery capacity. Turning on this morning showed the same 92% capacity. The battery at present shows 46% and has been used on battery for 6hr 23mins. This is with the wifi and GPS turned on but the screen brightness at about one third and the power saving turned on and a 32g sd card installed. I am very happy with the battery performance.

    Losing 10% in one hour of active screen time is *good*. That's ten hours active time. My 7.0 LTE gets just under 11 hours in my preferred ebook reader. Put another way if I'm using Opera a lot and playing Bard's Tale or something I get maybe six hours good use, roughly. I leave on the bluetooth, wifi and Smart Stay at all times thus far.

    10 hours screen on time would be great IMO.

    That is abnormally high. Check what's eating the battery in terms of programs.

    Could you explain how when turned back on I am able to see what has been using power in standby.

    The counter is only reset when you charge the battery, not when you restart. As I recall.

    But to my knowledge the device does *not* wake itself up.

    When in standby or sleep, if there is a Connection Optimizer like on my model it will control the wifi radio. Long enough without signal and wifi will be disabled, or if it probes and finds a recognized network the wifi will switch back on. For power savings.

    But you can check the battery drain and CPU time of both applications and some system tasks.

    Thankyou, I am afraid I dont fully understand your points I can say the wifi is switched off when in standby. I have checked it at various times and can say it is losing a pretty constant 2% an hour.

    Obviously the models with different hardware will have different behavior but...

    My 7.0 LTE lost 4% charge over ten hours. Enabled were "4G, Wi-Fi, GPS, Sound, Screen Rotation, Power Saving, Multi Window, Smart Stay, Sync, Connection Optimizer". I always hold Home and close all programs before I go to sleep, but the background services were still checking for new messages.

    I did not have my SD in it at the time.

    Do you have an SD card? If so, remove it and see how it peforms. Also, check out what is says is using the battery under Settings / Battery. Stop of delete those apps that are high users if possible.
