    So I've been doing some comparisons with these battery troubles I've been having. Doing one thing at a time to resolve them I've come to the conclusion that advanced task killer was in fact draining my battery one way or another.

    Monday
    Unplug at 8 am. It took 2 hours and two (2) 1 minute phone calls and my phone was at 79%. By 5 hours and 40 minutes it was at 31% - this was with the addition of 6 text messages sent and 6 received.

    Traded out the battery

    Tuesday:
    Unplug at 8:15 am. 49 minutes later I was at 91% battery life. Basically following EXACTLY the power loss that I was getting with the other battery.

    I uninstalled the Advanced Task Killer and noted that linear drop in battery level stopped - virtually flat lining at 90% for


    Wednesday:
    Unplug at 9:00 am. 52 minutes and 6 text messages later still at 100%.
    UPDATE: 1:45 PM. (4 hours and 45 minutes into it) After lots of text messaging, maybe 10 minutes on radio, and probably 5 phone calls ... from the same insurance saleswoman... the phone is at 80%. At this rate the phone should last almost 24 hours with this use. SWEET.




    And I was using the Advanced Task Killer to kill itself too.



    Also - not everyone seems to have this problem but I will tell you all right now my phone does a hell of a lot better without any kind of task/app killer than with it.


    Hope this helps some of you with battery trouble like I had.

    Wow, thanks for the heads up. Are you using any other method for closing idle programs?

    I am not using any other method.

    In fact I let my phone totally die yesterday so I imagine that footprints and all those weird things are running in the background... or idling in the background. And my power level is holding at least 3-4 times as good as the days before still. And this bitch keeps calling me lol

    Where are you getting exact percentages for your battery life?

    I have a battery widget that shows me, and also the hidden menu

    Dial *#*#4636#*#* and then press call. It has phone information and battery information.

    I had the same thing happening. Yesterday I went through the battery with minimal use...it finally died about 7:00pm. This morning I dropped from 100% to 75% in two hours. I uninstalled Advanced Task Killer and my battery has remained steady for the last two hours at 75%...lets hope this is the fix.

    Very interesting! My battery life would not last more than five hours when I first got it. So I installed Task killer ASAP the next day and have not seen any improvement. I will give this a try and see if I get the same results. Can you tell me if either of you have any Social apps (twitter, FB) running in the background?

    I have a facebook app. I imagine it is running in the background. I do not use the facebook widget as I feel it is pretty stupid. I also have facebook integrated into my contacts too so its imported most of their birthdays and pictures - but I have it set to only update every 24 hours as a precaution.

    I do have FB updating and running in the background...seems to be doing ok.

    I'm using Advanced Task Manager (not Killer) and have had no issues. I'm using the pay version. It was around $1 I think ... No biggy, just didn't stop at Starbucks on the way in.

    Thanks for the tip!

    **EDIT** And thanks OP for the original topic!

    I also updated the original post. 4 hours 45 minutes into it with moderate usage I'm only down to 80%. Comparing that with my Monday thats somewhere 2-3 times better.

    I'll experiment with Advanced Task *MANAGER* next to see if it screws things up.

    Thanks Andrew. I'm interested to see what you find with Manager (by Arron La - there are a few on the Market so I wanted to be clear on the one I'm using).

    I'm using the "other than stock message app" fix, but due to the relatively new nature of the phone the battery has not been fully "seasoned" yet and I only have one days usage of the Manager my results will probably change.

    Yesterday the phone went from 6:30a until 10:30p before the battery died. Some texting, some calls, a lot of web activity and "playing around" with settings, etc.

    Any updates on task managers or certain ones drainign the battery? I'm using the free adavanced task killer.
    I've also read posts where people are using nothing, letting apps keep running and getting much better battery life...?
    Tonight will be my 3rd day in a row of letting it die and then full charge. Then just charge whenever or?
    I am likely to get around 12 hours today with very minimal useage, needs to be around 14-16 for me to be fairly happy with that portion.

    I have used advanced task manager. I find that it really isn't helping my battery life and I'll probably uninstall it.

    Ok so not to sound like a complete noob, how do you close programs without a Task Killer. Im coming from a BB where i would just click menu then close but now when im in my browser do I just hit the home button? because when i do this and want to return to the browser, it goes back to to the last page i was at

    Another way to see the battery info is to open the voice dialer (I press and hold the green phone button to activate this) then say 'battery level'. It will give you an option of viewing the info.

    UDB, without using some sort of an app, I'm not aware of any way to close running programs. Which is so far the only major flaw that I've found with the phone.

    Why is it a flaw? Don't you think the phone might be smart enough to manage it on it's own? ;)

    As they are Smart Phones, your right they SHOULD be smart enough.

    Battery Life
    Battery Life is a major problem for a lot of people. I think it comes in 4 different packages:

    1: Battery : Do you drain the battery to zero or never let it drain down

    completely ? I do not know the definitive answer. It depends

    on who you believe and personal experience. I have not tried to

    drain the battery yet. (read below)

    2. Charger : Many people who have bought after market chargers have had

    interesting experiences from auto phone calls and emails made in

    sleep time to discharging while plugged in etc. I have several

    after market chargers, some work and some do not.

    3. Killer Apps : I believe they are helpful although they also drain battery.

    Some people feel that the LINUX system auto shuts down

    unused programs. I am not sure.

    I think TasKiller and Adv Task Killer work but use more battery.

    I personally use Adv Task Manager and find it works well for me

    4. Usage : Of course the biggest drain is usage. Any battery no matter how

    good will drain with heavy usage. i.e. game playing, listening to

    music, gps, bluetooth, wifi etc. The main drain is how long is the

    screen on.

    Conclusions: 1. Battery: defective ? Replace. Drain or not drain ???

    2. Charger: defective ? Dispose

    3. Killer apps: Do you need them ? I like Adv Task Management

    4. Usage: Review usage in Settings/ App - Spare Parts

    Modify especially in areas of low coverage. A lot of

    the programs kick in automatically and if your

    coverage is not good it continues to search and

    uses battery. That is what the Killer apps do.

    Let me know if there other thoughts on the matter.

A friend of mine has his mind set on the fact that you need to fully discharge a battery and charge it to full to maintain its longevity. The opposite though is true: 1) Each battery has a finite number of charge/discharge cycles so no matter what, every battery will eventually decline and die (i.e. these batteries do not have memory); 2) Several partial discharges with frequent recharges are favorable over one deep one; 3) Since our batteries are being measured by a gauge, 1 full discharge in 30 will keep the battery's circuitry calibrated with the gauge.

    These are just some tips. Again, no battery is going to last forever and typical life for Li-ion batteries are 2-3 years. And don't bother getting a spare battery, unless you're one of those users who just blasts through batteries.
    Agreed, I always have people telling me to discharge fully, don't overcharge, etc... and I always have to go on with this story.

    The batteries that benefit from this type of charging and discharging are NiCd and NiMH cells; which were once very popular until lithium-ion technology came along. Lithium-ion does not have this "memory" effect and does not benefit from fully discharging, conversely, it looses capacity in these discharges.

    Lithium-ion (or lithium-ion polymer) degrades based on the amount of "charging cycles" that it undergoes; each full charge (0->100%) counts as one full cycle. So, as sooper said partial discharges are more favorable over full discharges as they only count as a fraction of a full charge cycle.

    As for the charging overnight, modern charges, phones, and batteries all include circuitry to prevent the battery from being overcharged. You should be fine leaving it plugged in overnight.

    LOL - Oh I think the SHOULD be smart enough, but ARE they really??

    Actually I'm the same way about my computers, I just don't see the need for a bunch of stuff running in the background if there is no particular reason for it. I don't use Footprints or many of those other apps that run when the phone start ups. And I don't think every program I ever started should just hang out there and run. While I suspect most of them don't actually use much battery sitting there in the background, I just don't think they should run unless I start them.

    Of course, that could just be me. :)

    I guess if the app killers are draining the battery (to be determined), the other option would be to power down the phone every so often then bring it back up again. At that point only the default stuff is running, and not all the programs I ran 'yesterday'.

    Can I help you? You might use ATK too often, BTW, you should kill ATK also to save your battery life.
