    No actually it's not better. Every 5 minutes is a bit much but it won't eat up as much as a constant connection to the server. It wont be a dramatic difference by any means but polling no matter the time in between checks is better on the battery than having a constant connection.

    yeah battery life is utter crap with this phone.

    I've been testing it today. Results so far today:

    took phone off charger at 11:30 exactly. It's 1:32. So two hours an it's at 55%. The phone as had zero use today. No phone calls. Wifi on, GPS off, no apps open. Full signal bars. email pushed only as received. I've only gotten 1 emails today total over 3 accounts on my phone. And i did not use the phone to check the email. I used my laptop. That's the only reason i know how many emails i got. The screen was only only even on for the 30 seconds it took when i just checked the battery percentage.

    2 hours exactly and no use and it's almost half dead. right now my phone has just over a 4 hour standby. I mean that's pretty unacceptable.

    When I got 1.4, my battery was dead in 4 hours with light to no usage. But after deleting my backup and creating a new one, I am usually still at 60% after HEAVY usage 10 hours later!!! Not sure why this worked...someone suggested a corrupted backup was causing the phone to constantly try to update something that was no longer there, but whatever the reason it made such a HUGE difference that it is like a completely different phone!

    Worth a try, nothing really harmed in giving this fix a shot.
    how do I delete current back-up

    Changing how often it checks for email really does make a diff. I had an account checking for emails as they come and my batt would waste 7-8% an hour. Today i set it to 15 minutes and it has only wasted 7% in 2 hrs and 35 minutes I'm actually amazed right now lol. I love my Pre even more now.

    When you turn off the automatic back up, it gives the option to delete the current back up.

    My 1.4 battery life went down for about 2-4 days after install and is now back to normal. Not great but no worse that 1.3.x

    I doubt it's the LED notifications because I turned those off on my dad's phone and it still drains like crazy.

    wifi = no battery life. If battery life is a concern turn wifi off. Thats what I do and I am pleased with my phones battery life. I can go about two days like that.

    WHAT? really? i assume you don't use it and keep data off, correct? or did you buy a new battery?

    the cell radio which is always on which is why they can be truly be
    pushed from server to phone. Email comes through direct data connections
    to the email server and if you look at Wifi radio for instance, it goes to
    sleep when the phone is asleep. There is absolutely no way for the server
    to make an inbound data connection to you while the phone sleeps.
    It just won't respond.
    Beyond that, it's simply not how exchange and IMAP connections work.
    They open an outbound connection to the server, and just leave it open
    forever. Ideally the data radios can simply go idle and that connection
    stays open, but many things between the phone and the server
    can break that connection at any time, and when they do the data
    radio has to wake up to reestablish the connection, which costs power.

    People keep making generalizations about 1.4 that in fact only apply
    to a minority of people.

    See my reply above. From a pure English language parsing of the
    phrase "as they arrive" your belief in how it works would seem to make
    sense. From a computer perspective, there's simply no way to know
    when a message has arrived unless you're listening all the time.
    Since the mail server can't open an inbound data connection to your phone
    even if the protocol supported it, the only way it can listen all the time is
    to maintain an open outbound connection from the Pre to the email server
    all the time. Sometimes that can be maintained in a fairly low power
    state, and many times it cannot as it keeps timing out and having
    to be reestablished.

    Polling every 15-30 minutes does not cause high battery drain. I have
    two polling email accounts and have achieved 60 hours on standby. How
    about you? Anyone else with "as items arrive" ever manage that?

    you just did that yourself

    I don't know why it is that some members claim great improvement in battery and some members claim the opposite in battery life EVERY update but honestly, I've never seen any noticeable battery life change with ANY update and I've had the Pre since release.


    It might be a psychological effect of reading "better battery life" on the changelog, it might be because some people use their phones differently and the new update changes how that affects battery life, I don't know.

    But honestly, I've seen +/- 1% change (thus no change) per hour with ANY update palm has released.


    There is one thing I want to point out that may account for this, but I don't know.

    When you go from "100%" to "90%", depending on the true battery percentage, you may only be going from 96% to 90%!
    Seriously, so maybe that's attributing to it?

    It's not purely psychological, and it's easily measurable.
    I've run the Battery Monitor app almost continuously from the day it
    was first released, so it's been very easy for me to quantify
    the battery behavior with each update. It improved slightly with 1.2.x
    It improved a lot with 1.3.x. It hasn't changed much, if at all with 1.4x.
    With the early WebOS releases I was happy to get 1 day of standby.
    Now I'm up to 2 1/2 days of standby, and a full day of fairly regular use.
    It used to idle at 3-5%/hr drain. Now it idles at < 1.5%/hr.

    And yes, due to the way the phone protects the battery from overcharging
    the UI may indicate 100% when the actual battery level is anywhere between
    95-100%. If you run battery monitor and leave it on the charger you'll
    see the level on the graph go up and down in a regular wave pattern.
    There is a patch to display the actual % in the status area rather than the
    placebo %.

    And where are you at the times this happens? I see that sort of behavior
    when I'm in an area of poor or unstable Sprint coverage. Sometimes it will
    even indicate 3-4 bars but it's only because the phone can hear
    the tower clearly but the tower can't hear the phone, so it's cranking up its
    power level to the max to try to reach it. Same thing happens with "dumb"
    phones but they don't try as hard to stay on the primary network.
    I usually find I can work around those problem areas by forcing the Pre
    to roam, and it usually finds a closer roaming tower and can reduce its
    power consumption. Of course then data is slow, but at least the phone
    doesn't die in < 4 hours.

    Of course if you're actually just playing 3d games and/or streaming
    music, then it's going to suck the battery down at 20-25%/hr.
