    Impressive amount of data presented.

    Only question I have is, why are you doing nearly full cycle deep discharges and allowing the battery to stay on the charger past full saturation when you specifically recommend that users should only charge between 25 to 75% to maintain battery health? Source - http://www.droidforums.net/forum/sm...ion/198191-white-light-death.html#post2117585

    Or are you planning to follow your own advice next and show what happens with the same graphs over another 4 day period?

    When I first got my Maxx I could go 1 day 20 hours between charges (charging when I got to 15%). Now that I have had it a while I get 20-24 hours. Simply because I use the heck out of it and use no smart actions at all. Still, going all day without having to charge is very nice

    Good questions...

    First off, I am not concerned for my own battery's longevity at the moment (and really not at all). I fully expect it will meet or exceed my need for longevity.

    This extended charge and usage cycling didn't start as an experiment, but out of necessity since having both my wife and father-in-law enter the hospital on the same weekend (Labor Day Weekend), and both requiring emergency surgeries (wife with complications to cancer and previous surgery, father-in-law with a broken hip). This unique and completely unexpected situation had me instantly thrust into the combined role of Mr. Mom, housekeeper, & (already) breadwinner, while also being a supporting husband, father, son-in-law and caregiver. The strain of my son's school bus schedule, my work commute, stress of the surgeries, recoveries, long hours in the waiting room, and then trips back and forth to the hospital kept me out and running around non-stop from wake to very late sleep each day. In the initial 36 hour period I didn't sleep at all, and wasn't even "sleep" tired.

    During those days, I had been using it very heavily and came to respect the battery and system even more. Now that my wife is back home and amazingly well recovered after her extensive surgery and a week as an admitted patient, I have resumed a somewhat more normal schedule though it has been still more running around than usual, though my father-in-law (who busted his hip) will likely be an inpatient for therapy for several weeks still. So, it was during this more recent period, since my wife's release from the hospital, a less stressful period of time that I decided to turn necessity into an experiment.

    I was simply looking to see if I could get a good picture of what the battery was really capable of from a full saturation charge to the bottom of the safe discharge limits, since there are many who complain that even the MAXX battery isn't meeting their expectations. This was an experiment to test the boundaries. In order to get the results charted, I had to disconnect the charger cable on my car Navigation Dock so I wouldn't interrupt the discharge cycle with a charge cycle and thereby prevent getting a true reading of capacity and duration of discharge. Yes, as in any experiment where you push the envelope into uncharted territory it may do ever so slight damage to my battery's long-term health, though miniscule relatively speaking considering how few times I would have done such 85% discharge cycles, but I know that going in and will not be blaming anyone if the battery doesn't continue to provide me with what I feel is a fair day's use at some point in the coming year or two.

    As for second comment it's actually a very good idea. I hadn't thought of doing such a system run and charting it because there would be miniscule if any way to evidence the benefits long-term to such charge/discharge patterns unless I did so over a reasonably long sample period and number of cycles. Extending out the data could point to a trend by looking at the relative reduction in the total capacity for the sample period. However the length of time and cycles that sample would have to run is likely longer than I wish to devote to such an experiment, but it's still a good idea.

    So to summarize, what I do personally with my phone is both my choice and doesn't have to be representative of the recommendations I put forth for others who are looking to achieve something that I am not concerned with - extending the life of my battery. Others may be concerned simply because it's designed not to be "user-serviceable", but I've had these phones open before, have removed motherboards, and have replaced digitizers, displays and cameras, and know that if I needed to replace my battery I could do so successfully and with little risk...but also that if I screwed it up I wouldn't then place a false warranty claim in order to get the phone replaced at the expense of the company.

    The experiment is done. I've closed the books on it today, however my pattern of usage and charge will be unique to me, and since I choose to plug in at bed, I will be charging to full saturation every night (and yes, decreasing the long-term performance of my battery in doing so), and will also be performing interim charges as I commute to work, to the store, to the hospital to visit my father-in-law (who turned 94 today), and to wherever else my days may take me since my phone resides in the Navigation Dock from the moment I sit down in the pilot's seat until I am preparing to disembark. As well, it may be partially charged at times during the day while at the office or home if I am doing direct USB transfers although that is a process that I do few and far between with the intervention of wireless data transfers.

    Today, I unplugged at 11:09am, and it's now 1:52am, almost 15 hours, and my phone is showing 70% remaining. I have concluded that the battery in the MAXX, when charged to 100% capacity (full saturation charge), and used light to moderately during the day, can easily provide 2 days of such moderate use (or about 36 hours - daylight hours with an overnight in between), without an interim charge, and also can easily supply sufficient power for a hard day's work on the same charge. For me, it's going to be difficult to get into the "zone" of 25% to 75% and stay there, but I'll be giving it a whirl over the coming weeks.

    These past couple weeks were a dramatically unique period in my family's life, one I hope to never even come close to repeating, but fortunately it appears that we are all on the road to a collective recovery (though dad has a hard road ahead of him).

    Thank you so much for your kind and genuine compassion. My wife is in a good place now, health wise, our major concern for the foreseeable future is her father, my son - age 9's "pop pop", his best friend, my wife's last remaining immediate family member and the closest thing to a real father I've ever known.

    Thank you again.

    Fox, I'm gonna get lotsa +1, ditto, etc on this one:
    I pm'd you on this awhile back. Do you listen? Noooooo.
    The oncology RN in me reminds you that you cannot take care of your family if you don't take care of yourself. I checked......Your last post was 3 am...your first post was 9 am. Add time to get to sleep and wake up and you slept about 4-5 hours after being sleep deprived for a few days.
    Buddy, your family needs you at 100%; furthermore, we want you around the forum for a long time to come. Get some rest.
    Put the phone down, step away from the forum sir.
    We promise to take good care of our batteries and behave while you are out playing with Mr Sandman :)

    :hail: Thank you for those words of wisdom. You are right. I was actually up till 5:00am, so it's even worse than you illustrate. The difficult part is, I don't feel "tired", but yet I'm "exhausted" during the day. When I try to sleep, I lay there and stare at the ceiling, hear the Mockingbirds in my immediate and very wooded area behind my yard and around my home. I have wildlife - from large to small...Deer, Foxes, Raccoons, Groundhogs, Skunks, Cats (wild strays), Squirrels, Chipmunks, and all other manner of creature that thinks my home and my family are simply fixtures of the forest. The Mockingbirds sing all night long, and when we have the windows open to catch a cool breeze they serenade us for hours.

    I will heed your wisdom and try to get more sleep, but I am addicted to the great people that make up this community, I really feel like you are all an extended family, and when my genetic family is so small (4 including me), this place really does nourish and enhance my life. Thank you and everyone else. :hail:

    Thank you for your honesty and for finally clarifying that you won't be practicing what you preach.

    Whatever! :blink: There is a thing known as selective listening (and perhaps reading)...

    What one does with his or her phone is completely personal and unique. To say that for myself I am not concerned with the battery's longevity neither negates what I've said regarding how to extend the life of the battery for others' batteries, nor what I've said will shorten the life of same. It's simply that for me it's not a concern. For others it may be a huge concern and the information I've provided (which by the way IS 100% accurate, whether you choose to accept it or not), WILL enhance their user experience.

    I'm done with this "debate" as it is obvious that all you want to do is "prove yourself" and at the potential detriment to the members of this forum who look to us for accurate and valuable advice in order to resolve their concerns.

    I've tried to be civil in every response to your repeated public lambasting of me (one of which you were questioned on and felt pressured to edit in order to retract your direct attack on me), but it seems that no matter how much I try to convey that my ONLY interests in promoting proper battery care is to BENEFIT the MEMBERS for whom this is a genuine concern, and for those who aren't aware of what damage they may do if handled incorrectly, your only interest is in "winning" the "debate". Whether I choose to use the same techniques I describe to extend the lifespan of my own battery or not is in direct proportion to my personal level of concern as to whether the battery will last long enough to serve my personal needs.

    I'll let the public judge me, and either verify or deny my claims as accurate, and will stand ready to accept their complements or criticism whichever they may be. For me, you are in a different category.

    P.S. I will not be responding to any future posts of yours, as I am hiding you from my view.

    Why would someone who isn't having battery problems care? On top of that why would a fellow tech nerd (like myself) care if a new phone and battery is right around the corner.



    Yes, I feed the trolls ^_^
