    My dad got the new DROID RAZR maxx. And as soon he came home today I offered to set it up:D As soon as he gave it to me, it was at 20% battery. So I shut it off and started charging it via the wall charger. Am I charging it right to "calibrate" the battery to its full potential? If not, what should I do? And what other things can I do to bring the battery to its legendary battery power? Thx in advance.

    First of all, you are calibrating the battery meter. The battery itself does not need calibrating or conditioning.

    You're off to a good start. Continue charging with it powered OFF until it reaches 100%. It will take longer than you're used to with the Razr. You can check the charge level with a quick press of the power button. Once fully charged, power ON and use normally until you get the low battery warning at 15%. Power OFF and charge to 100% again. Then you're good to go -- use normally and charge as needed. This procedure should be done every month or two.

    I'm sure your dad will enjoy his new toy.

    EDIT: It is not necessary to charge to 100% all the time. Small charges of short duration do not harm the battery. In fact, there is evidence that this will prolong battery life.

    Good. Once the calibration cycle is complete, tell your dad to use as normal and charge as needed, but never intentionally kill the battery completely. Not saying bad things will happen, but bad things can happen. The 15% low battery warning is there for a reason.

    Earlier you asked about other things you can do to optimize the battery. Nothing different than you do with your Razr. It's the same phone with a larger battery - same radios, software, etc. Enjoy!

    Since you powered it off and started the charging again at 20%, you never actually set the low battery flag (which is set at 15%). This time, let him use it until it reaches 15%, or if he gives it back to you before it gets to 15%, continue using it yourself. It is important that the cycle goes:

    1. Charge to 100% with power off,
    2. Drain to 15% (not lower) through normal use,
    3. Charge to 100% with power off,

    Just in that order. The first charge to 100% sets the Full battery flag, the discharge to 15% sets the Low battery flag (hence the "Low battery" warning that pops up on the display), and the second charge to 100% confirms the range of charge from 15% to 100% to calibrate the meter properly. If you leave out any one of the three steps, you defeat the entire purpose for doing this calibration exercise as it will only add more confusing information to the meter and could result in further erroneous readings.

    Just use the phone like normal and charge as common sense mandates. You'll be fine.

    The problem is common sense is a relative term. For some, common sense is to use the phone till it displays 0% and shuts down on its own while to others it means charge at every opportunity, and still others are somewhere in between. Also, the battery has no common sense, its going to react differently to each individual usage pattern.

    It would be nice if the charging system were able to adapt to every individual person's unique profile and usage pattern but that's not the case and its been proven countless times that the metering system loses track of the actual battery levels and capacity. The method described above has been proven effective and documented by engineers in the battery industry. It has also been proven here in this and on other forums as well.

    I believe we can go as far as to assume the OP has sufficient common sense to realize that when his battery is getting low he should charge it. If you choose to think that the OP's level of intelligent common sense is so low that he would make the faulty assumption that you should only charge your battery once it reaches 0% and dies, then that is quite interesting and makes me wonder why you consider them to be so stupid. After reviewing some of the OP's posts in the past I had come to the logical assumption that based on prior knowledge, he has a sufficient amount of common sense regarding Android in general to be sufficiently competent to determine when to charge his battery. Considering the fact that he only gets to play with the phone for a little while before his Dad needs it back, it doesn't seem practical to expect him to be able to monitor the device closely enough to follow those precise instructions when such actions are absolutely not necessary to simply calibrate a new phone's battery meter. If the OP uses common sense to charge the device as necessary, I am confident, due to personal experience that the battery along with the phone will turn out fine and display generally accurate percentages.:p

    There is lots of old, bad info floating around. You would be surpised how many people believe that fully discharging these batteries is a good thing -- that doesn't make them stupid.

    Second, there are cases where the battery meter is not displaying an accurate level of charge. Here is a recent example.

    Dont let it get to zero % lol, At my last job I was lucky enough to work at a corp sales/repair store. The people who had the HTC evo (original) that let the battery to zero often had to come in and let us use our "special battery machine" for any hopes of that battery ever working again. Basically as far as I could tell it was a tester machine that also enabled you to change the volts on first few min of charge. Not really sure what it was, but SOMETIMES when your battery gets zero, you can't charge it again.

    Follow what motorola tells you about how to charge your phone. According to motorola who makes the phone they recommend you charge your phone at 75 percent of use before you recharge it. I tend to try and follow their recommendation when i can. But as most people will say its not always possible. Goto your news app and subscribe to their tips and tricks feed.

    So, I got my new Maxx two days ago (w00t!) and never followed this procedure - never knew about it until I came back to the boards and started catching up on RAZR/Maxx threads. Is this solely for meter calibration, or is there something about the battery itself that requires the procedure for improved battery life/performance? And if it's just an internal app calibration (I also use Battery Left for that sort of info, btw), how can I "reset" the internal app and recalibrate?

    No. It does not require this procedure that you see on this forum. But you should do a 100 percent charge when you first get the phone. Dont worry if you didnt. Like most people they dont do it either. Just try to follow what motorola says about charging your phone and the battery should improve and last longer. Check out the news app on your razr and subscribe to the tips and tricks from motorola. I try not to let my battery fall below 25 percent before i put a charge on it.

    I tried telling this to someone the other day but they wanted to argue with me about how people can't be expected to just charge their phone using common sense because everyone has a different definition of common sense and he proceeds to tell me how the method has been proven and how its necessary and blah blah blah- im trying to encourage people to use their brain n just use.a little common sense. If he sees this then galaxyflatulence will probably famously grab his popcorn as that other dude( I forget who it was) proceeds to want to argue about how u can't tell people to use common sense- they need to use the "proven" method lol

    Sorry, but it seems that you disagree with me, BatteryUniversity.com (parent company CADEX - arguably the foremost authority on the proper care of rechargeable batteries and the company that makes those "charging" devices Caesar referenced above), and also Motorola itself. There is truth to what you say in that most people don't fully charge their phone before initial use. In fact most often leave the phone store with it powered on and begin using it right away, or if shipped will power it up immediately upon removing from the box. Also, you don't need to "worry if you didn't" (for the most part true). You also mention charging to 100%, but without mentioning that the initial charge should be done with the power off, which is also eluded to in the manual since it shows the charging happening BEFORE powering up (*see below*). It even shows 3H (3 hours) charge length out of the box with the power off (see the little clock at the bottom in the left pane).

    Motorola RAZR Owners Guide Page 3.png

    You mention that you try to not let your battery fall below 25%. In normal practice that's a good routine to get into since you'll be using at most about 75% of the capacity of the battery before charging and it's been proven that shorter charge cycles are better for a prolonged usable battery life. However where I respectfully disagree with you is that as time goes on (we're talking months here), the battery's capacity REDUCES (not "improves" since it can never improve beyond it's capacity from the factory - not even during the first week as some claim), and as its ability to take a charge diminishes, the charge level that meter indicates will skew from the actual capacity such that when it says you have 25%, you may have substantially less. If you never let it fall to 15%, it can not adjust its reference points for "Low battery". This sets you up for possible problems down the road including boot-looping, failing to charge and more. Also, if you don't charge to 100% with the power off, you're not giving the meter an accurate reference point for the true capacity of the battery at that point in its lifespan either.

    There have been countless threads detailing both sides of this issue, and as many on this forum know I've done extensive research and provided credible references to back these recommendations. I am not going to go too much deeper on this than to say that unless you follow the 3-step process either on purpose or accidentally on an infrequent basis (about every couple to few months) and first to charge the phone to 100% with the power off, then allow the phone to recognize and reach 15% or lower battery level followed by a 100% charge with power off again, you are likely to eventually suffer some of the same symptoms others here and elsewhere have, even after only a few short days or weeks of ownership.

    Case in point, there was a user who had the phone only several days and yet the phone seemed to be "dying" in a couple hours. This was a Droid RAZR MAXX if I'm not mistaken (correction anyone?), and at one point during our attempts to correct his issues he indicated the phone had been at displaying 5% for 7 hours straight while playing music, which explains why he thought it was "dying" after only a couple hours when going from 100% to 20%. That's the most obvious indication of what I'll call "battery meter divergence". The explanation has been detailed here several times before but it has to do with how the battery voltage levels fall during discharge and at what point it becomes obvious to the meter that the battery has reached near complete discharge.

    If you want the technical details I can supply the links.

    I believe the "dude" you are referring to is me (http://www.droidforums.net/forum/droid-razr-maxx/207644-new-droid-razr-maxx.html#post2100171).

    I will say this, I don't go around gossiping to others about how bad or wrong the advice someone else gives another is, whether I am right or wrong. I approach every debate with respect for others, since in a debate there is always something to be learned by both sides.

    As for common sense, manufacturers struggle with this very issue constantly. There is a reason for a safety on a gun for instance, and yet somehow people still shoot themselves and others accidentally every day.

    I would like to see everyone using it as well. Unfortunately that's not the case and many times we see the ill effects of those epic failures. You are free to believe that everyone will do the right thing, and as long as at least you do the right thing, you're likely not to suffer for it. However I am trying to better the experience for all users and for the forum, and if everyone always did the right thing, or even remained within a margin of common sense, we wouldn't have nearly the number of "dead battery" threads here, and the Emergency Rooms in hospitals across the globe would be far less busy.

    That's not to say that some of those folks didn't have real issues with the phones and/or batteries. And I am also not implying that lack of common sense is the reason for all the other failures. Seriously, are we even going down that road? I hope not.

    MOST failures are as a result of not following directions, pushing the limits, being distracted, having other priorities, etc. Could they have been avoided, well in a word - yes, in most cases, but not necessarily by either "having" or "applying a greater amount" of common sense, but instead by simply paying attention.

    There must be something to my words that ring true for others as indicated by the likes.
