    So I'm on my second touchpad (because I found I could grab a 32gb for less than I paid for the original 16gb).

    It seems like my 32gb gets slightly worse battery life than my first one. I installed Dr. Battery and it says the battery is rated at over 6600mah, but it's at 95% health so just under 6300mah left (mind you the touchpad is spec'ed with a 6300mah battery).

    What is everyone else finding with their batteries and Dr. Battery?
    32Gb LG G2 - 4.2.2 Jelly Bean
    32Gb TouchPad webOS 3.0.5 / Cyanogenmod 10.1 (4.2.2) Dual Boot @ 1.8Ghz

    RETIRED:
    16Gb Pre3 webOS 2.2.4 @ 1.9Ghz - Mine
    32Gb TouchPad webOS 3.0.5 @ 1.8Ghz - LunaCE 4.9.5 - Also Mine
    16Gb Pre3 webOS 2.2.4 @ 1.9Ghz - Wife's (replaced with GS3)
    32Gb TouchPad webOS 3.0.5 @ 1.8Ghz - Also Wife's

    Past: 2 Sprint Pre(minuses), a Sprintified Pre+, and a Sprintified Pre2.

    Haven't run Dr. Batt on it yet but was just going to make a post to "State your battery life" but I'll chime in here as well.

    Took the TPad off the charger this morning at 9:30am and used it all day at work and all evening since I got home (all P|C posts tonight) and it's 12:50am with 15% to go. 6 email accounts, 4 calendars, browsing our intranet and sharepoint sites as well as the Cisco call manager portal, some personal surfing at lunch, and a little Robotek HD. That's 15+ hours which is typical for heavy usage. Light usage I charge it every other day or so. Not sure what the heck Engadget does to get so poor a time.


    Getting ready to charge her now.

    I ran Dr Battery out of curiosity after reading this. Like you, it states the Manufacturer Rating at 6612 mAh. It shows the health at 95% or 6681 mAh. I got mine on 1 July.

    On a more subjective note.... When I use it for 16-18 hours for easy things like email (7 imap accounts), browsing websites and apps like news/magazine/book, my TPad will drop down to around 30%. Total cumulative usage time is around 4-5 hours.

    My heavy use has been graphic-intense games, streaming video and multi-tasking that sucks down the power. I haven't tried watching a full movie yet. I think at the worst, I was able to use up around 25% of the charge in about an hour of solid use.

    I am curious to know if that's normal for tablets in general, not just the TPad.

    It's recommended by the manufacturer of the chip inside the battery to use a higher "Manufacturer Rating" than the actual battery rating.
    With that you have some room for calibration if the battery has more than specified.
    With that a "normal" new battery don't has 100%.
    But the calculated capacity should be around the specified capacity for a new one.

    Honestly, I might just be paranoid. I've been using my TouchPad more and more, so that's obviously one reason. I just thought one night my touchpad lost 5% where the last one didn't lose anything and all the accounts should be the same. It's probably nothing...

    Totally anecdotal:
    I performed a secure erase last night. The final third of which while on battery. Once it came back up I set up 5 email/calendars; downloaded and configured 20 some odd applications; paired with Pre minus and Touchpad keyboard; launched Kindle app and then read for a few hours. The thing was in constant use for 7 hours and when I set it down, I still have 35% battery left.

    If that's crappy battery life, I'll take it every time.

    Dr. Battery said mine was 95% when new too.
    I maximize battery life and stability by hitting airplane mode whenever I'm going to walk away from it for a while.

    Has anyone heard of bad batteries for TP? After a night of recharging on Touchstone, it dropped to 75% after 15 minutes of email and browser use. I haven't put the TP through a whole day torture test since my use is very intermittent. Does that sound right? I may have to return it to HP for a new one then. I noticed a small crack in near my speaker too.

    From 100 to 75% in 15 min? That's not good.

    Machine is OC @ 1.78ghz
    Bluetooth wireless keyboard is active.

    I figure I watch a video and see how long it last
    *****Stream watching ESPN HD on the TP for past 1hr 30 min or other Media streaming from website non stop to see how fast can I drain this battery.
    Battery went from 100% to 53%
    Dr Battery shows 52% (not too worried about 1%)
    Battery Life as per the program shows 95%

    Once battery is drained, will charge it using touchstone fully and then going to watch a video directly from TP and let it just run. See how long that takes before it drains off

    Run it down to zero a couple times and see if it improves. If it doesn't then return it for a repair/replacement. My two cents.

    Where do you find "Dr. Battery?"

    streaming video and pdk games like need for speed are the biggest possible battery drain.

    That's what I am trying to see for myself. So I now what to do and what not to do.

    1hr and 45 min of streaming HD content via Internet to HP touchpad and battery is 49%
    And email, facebook, skype, keyboard all in the back.
