    Have you ever tried actually timing your battery life? Mine also gives about 3-3.5 hours estimates but I get closer to 4-4.5 of continued light use I would say.

    WHen I bought it, it first came out claiming 7 hours which was with hp quick web ( not w 7) and later the hp site claimed that this battery (stock) could get 3.75 hours of battery life...

    NOW, it says 6 hours...
    did they buff up the battery?

    And also, kind of unrelated but what the hell is going on with the radiance option? It seems to come and go!

    wow .. it seems battery life on the envy 14 is not constant and it really depends on alot of factors .
    im in a dilemma now . i have a bright red pixel on my radiance screen and im thinking of rmaing . shld i go to the i5 for the batt life on the beats edition and nt have the radiance screen ? ( only available with i7 )

    if its only 1 hr diff , likely im sticking for the i7 .

    btw y are ppl particular about batt life ? dont schools provide wall sockets =x
    do ppl actually game on batt life ?

    No its so you don't have to carry around power plugs when you go study in the library.
    Macbooks seem to hold up 5+ hours when just lightly browsing or word processing and for pcs like the envy 14,which is more powerful than a macbook, we hope that it can also have the battery convenience of a macbook (or pro)

    I get like 2.5 hours doing light stuff with mine...what's wrong? How much does brightness affect it? I really can never get longer than 3 hours even with low brightness, and it's really getting a little annoying :(

    Where are you getting this 6hrs battery life at?
    Nevermind, I see it... did they change the battery??? I think I am going to ask them about it.
    I'm on day 16 of owning my envy.

    If you want battery life just get a slice battery, really, the i5 would only get you about an hour more. I'd advise you to just stick with your i7, it's a lot more powerful and you get that radiance screen. But the brightview is a good screen too, and the beats edition really looks very nice :)

    for those of you who actually get 3 hours of battery life or less (this is timed by you, not by the battery bar program which is a big guesstimate)

    I'd call HP and try to get a replacement battery to see what's up.


    ...well first I"d make sure a program isn't running and using up one of the processor cores.

    Just a quick tidbit. For those of you complaining about the Envy 14's battery life and saying you're just going to grab a Sony Vaio Z instead, you may want to reconsider:

    Review HP Envy 14-1010eg Notebook - Notebookcheck.net Reviews

    Review Sony Vaio VPCZ11X9E/B Notebook - Notebookcheck.net Reviews

    Note that in their review, the Envy 14 achieves 4:23 at idle, while the Vaio Z gets 7:43. Impressive for the Z. Now look again at the other battery statistics. 3:55 when surfing for the Envy 14, and 3:10 for the Vaio Z. Whoops, what happened?! The rest of the battery tests are similar as well, slightly favoring one computer or the other. It looks like Sony managed to really turn down the idle consumption on the Z, but other than that they're just about neck and neck.

    Of course, this is just one laptop vs. another, but it still puts things slightly more in perspective. Yes, it sucks that HP originally claimed 7 hours out of the Envy 14. However, when you look at the entire package and consider the fact that you have the OPTION to add on a second battery (in a very nice package, I might add), ~4-4.5 hours seems entirely reasonable to me.

    That's my $0.02.

    I was curious what the real idle time of the Envy 14 is.

    When the Envy was first released HP reported a batterylife of 7 hours, then they adjusted it to 3.75 hours and now it's up to 6 hours again. All with the same Envy 14 and the same battery.. We all know how the manufacturers usually determine the battery life. It's the battery life you get with everything turned of. A time you usually can't reproduce yourself. So I decided to see how long it would last on idle, with the screen turned on:

    HP Envy 14 1020ED
    -Radiance screen
    -i5-450M
    -500GB 7200RPM HDD
    -Intel GPU
    -Bluetooth off, Wifi on and connected to the internet
    -Power saving scheme
    -Windows 7 Prof X64, clean install
    -Aero glass on
    -Screen on lowest brightness
    -Screen wasn't allowed to turn of
    -I barely used the Envy and just let it idle. Let's say it idled for 95% during the test
    -Standard battery, no slice

    I got the 10% warning after 6:02 hours! I think it would be able to hit the 7 hour barrier easily with WIFI turned of and Aero glass turned of. The tweaking I did to the Envy:
    -Clean install
    -Turned down the Wifi transmitting power and roaming aggressiveness according to: http://forum.notebookreview.com/hp-envy-hdx/501066-envy-14-battery-life-log-26.html#post6540061

    For normal use (constant browsing, IM, mail, youtube) I get 4 - 4,5 hours out of the Envy.

    I previously claimed in this thread that I was seeing a pretty consistent 20% per hour battery draw with light usage (flipping through powerpoints, wifi on, opening firefox periodically, 60% brightness, aero on, modified balanced power setting). Well that was with BIOS F.06

    Last week I upgraded to F.13a and the results have been even better. I'm now seeing 50% battery usage after 3 hours (or 3 hours 20 minutes if WiFi is off most of the time, only turned on when needed). Batterybar estimates between -8,500 to -9,500 mWh for the bulk of the usage period.

    Again, I think the key is to set the HD turn off time to 1 or 2 minutes (as well as maximum battery saving settings for the wifi and integrated graphics of course).

    The trade off of the BIOS seems to be that my idle temperatures when plugged in are much higher even when using integrated graphics. Used to be around 30C on integrated now it's about 40C on integrated and 45 on discrete. Temperatures on battery seems to be the same though.

    Either the newer BIOS is keeping the fans at a lower RPM or off (to save power?), or the ambient (room) temperature increased between the two scenarios.

    The only reason I can see to do so would be to decrease audibility, but the fans are at least as audible as they were before. Minute power savings when on A/C power are a moot point.

    Damn, you got me there. Maybe I shouldn't have evaluated the BIOS changes in the sauna at the gym. :rolleyes:

    Anyone know if there's any easy way to switch from battery power to direct AC power when plugged into an outlet. Having to take the battery out completely seems a bit ridiculous on a regular basis. Anyone tried this yet? Might save a lot of battery wear if you use your lappy at home.

    I think he means without charging the battery - just direct AC power

    any more reviews for the i7-840? I'm picking mine up in a minute, still kinda curious what other people out there are getting, although it doesn't seem to be a popular configuration :lol:.

    One guy claimed 4+hrs out of his w/o slice, if I can see ~4hrs without the slice I'll be happy, otherwise may need to "downgrade" to the i5.

    That's at idle after a clean install. Realistically you'll get about half of that.

    i7-720
    50GB SSD (replaced stock 500GB HDD)
    Radiance screen
    Standard Battery
    Clean Install
    Bluetooth off, Wifi on
    Balanced Power profile
    Screen brightness 3 notches below maximum
    edit: Web surfing, MS Word


    2:51 before getting down to 3%. Discharge rate varies from 14k to 26k. I'm now on my 4th run and the battery is at 44%. BatteryBar says that i have 1:23 minutes left.

    I was initially very disappointed with my battery life prior to replacing the HDD with and SSD and doing a clean install. Best i could manage was >2:00 with a constant discharge rate of 25k before hibernating. I'm now very pleased with my results considering my processor and screen size.
