    I have heard many different opinions on this topic. I was wondering if it is really necessary to condition your phone battery when it's new. I've been told to charge it completely and let it die completely 3 or 4 times to get it conditioned. Is this true? What benefit does it give?

    Yes, it does make a difference in how the meter reports the true state of charge for your battery. It is best to do the procedure every two to three months because the meter that reads the battery's state of charge, over time, will report inaccurately. Following this procedure will correct the inaccurate meter reading.

    The steps to do a battery meter training:
    *with phone powered off, charge it to 100% (you can check the % of charge by pressing the volume button).
    *When it reaches 100%, turn phone on, unplug, use your phone without charging it until it gets to the low battery warning (10-15% charge).
    *Turn phone off and charge it while off until it reaches 100% again.
    *Turn phone on and use it and charge it as you normally would.

    Thank you! Awesome info to have. I also didn't know it should be done every few months. I'll stick to it. I appreciate your response. I quickly became addicted to new phone technology and I can't shake it. I research everything I can. I'm still a little nervous about rooting, but I also have a Mac for a desktop so I don't have much of a choice anyway since there doesn't seem to be a whole lot I can do without a PC. Thanks again! I'm new to the forum. This place is awesome. Lot of good advice and cool people here.

    Thanks! This is a great place for pretty much anything you want to know regarding android. The thing with the battery is that it's not the battery that has deteriorated or weaker but it seems like it is because it doesn't last as long before the low battery warning comes on. The reason is because the phone's battery meter gets off and may report the battery as having only 10% charge when really it actually has 50% charge... or it reports that is 100% fully charged when really it has only reached 20% (or something similar). Charging it while the phone is off ensures that it reaches a full 100% interrupted charge and sets the meter to read it at true 100% charge. Then using it til you get the low battery warning and turning it off again to charge sets the meter to read the low level accurately. Many people who thought their phones were charging too quickly and draining too soon immediately saw the difference after doing the meter training/recalibration.

    Have fun with your phone and join in, ask questions, and read...this forum has a great community.

    Hello,

    Does this work only for the RAZR MAXX HD, or for Droid smartphones in general? (I'm assuming the latter, but would just like to make sure.)

    Also, if this battery depletion/recharging procedure is only begun after the first several d/r cycles, will the battery (or battery meter)'s performance continue to be less than if the d/r procedure was followed from Day 1?

    Thank you very much, and keep up the good work!

    Yes, it applies to all phones but I suppose it may be possible that some phones (or the way the phone is used), the meter that reads the state of charge could maintain its accuracy for longer period of time.

    2nd paragraph: The battery-meter calibration procedure should be done ever 2-3 months and can just be used and charged as you typically would in between. I don't think the performance will be less if it wasn't done from day one or even from day 30. Chances are the meter is pretty accurate brand new. But what is best for the battery's performance is if it is fully charged before the first time it is ever used. But this rarely happens... I know I have never done it, lol. But the affect of not doing so, I believe, is so minimal that I'm not certain the difference would be noticed (ie. If you had two of the same phones; one you fully charged immediately brand new; the other you used right away. Would you notice or even be able to measure the difference in battery performance.

    I think that answers the questions (or answered more than you needed, lol).

    Beyond the advice given...i have read that normally it is good for your battery to keep it between 20-80% charge at all times. Overcharging and letting your battery kill your phone are not good for the overall life of your phones battery.

    I did exactly what you said this weekend with my battery. Is this something that takes a while to improve? My battery is worse than ever now. I usually have about 50% around noon. I start work at 5. At noon today I was at 22% and it was falling fast. I could actually watch the battery go down about 1% every 30 seconds or so. Doing nothing but having the screen on. I'm just wondering if this will get better after a few charges. Thanks for all the advice and input!

    No, it definitely should improve. There is something draining your battery that shouldn't be. Was your data on but poor data signal? Make sure your phone is not in global mode... go to settings --->more... (under data usage) ---> mobile networks ---> network mode ---> select LTE/CDMA.

    Thank you for the response TisMyDroid! I checked my settings, and it's not global. Everything looks the same as before. I installed a battery manager app, even though I don't believe in them, and it actually helped a little. I may try to condition my battery again. I know that the first time I realm my battery down the first time, I didn't run it to 10 or 15%, it actually ran all the way down and powered itself off. Maybe that's part of my problem. I actually have a stratosphere right now, horrible phone anyway. The reason I posted here it's because I'm grabbing the razr Maxx next week, and it seems like there's more general knowledge on these threads. You guys rock. So hopefully I won't have to worry about battery life anyway. So I'll just try the conditioning again and see what happens, unless that's a bad idea. I think I'll wait to hear from you or someone else before I do it again. I really do appreciate all your help and input.

    Thanks for the appreciation. Doing the meter training won't hurt if you try it again. It is possible that the stratosphere's meter is not as effective in calibration but it won't hurt to do it again.

    TisMyDroid, thank you very much for your advice!

    As it happens, I fully charged both my wife's and my new phones first time out, since the instructions suggested it.

    Keep up the good work!

    STOP!! You're revealing my sources! :rofl3:

    But seriously, it's NOT the BATTERY that benefits from an infrequent training...Lithium based batteries, and in particular the LIPO batteries in our phones (Razrs, et. al.), are unaffected by the problems that plagued Nickel Cadmium rechargeable batteries of the past, where they would being to essentially "forget" a portion of their capacity if it weren't regularly exercised.

    In our cases, it's the metering system that needs to be both reminded and adjusted to recognize properly the maximum and suggested minimum capacities or State of Charge, since it's not something that is fixed and static. As these batteries age, they can hold less charge. Without refreshing the "flags" for maximum and minimum charges stored for the metering system to the new, aged battery levels, the meter will eventually be misrepresenting either or both, which can result in potentially deep discharging a battery and rendering it useless. Often the damage is only temporary (White light of death, bootlooping, etc.), but it can be permanent.

    To the OP, you do NOT need to do this when you first get the phone, but what you SHOULD do is what JeffreyDeutsch above did...charge it fully WITH POWER OFF, and BEFORE activating it, to assure both that you've set the proper level for the maximum charge flag, and so that you don't accidentally deep discharge it by using it right out of the box. Otherwise, this "meter training" should be performed about every 2-3 months, depending on how much you use the battery - more use, train more frequently.

    Also, as someone else pointed out (sorry don't have the name in front of me), using the battery and charging it within a range of between 20% and 80% will actually result in a longer lasting battery over all, versus charging to 100% and draining to 10%. These batteries actually prefer several shorter charging periods, partial charges rather than long and full charges, as the shorter charging cycles produce less internal stress on one of the battery's primary components, namely the anode. So plug in when you are near power sources, carry an adapter in your shoulder bag or back pack, and don't forget to use the car adapters as well. Instead of "feed and starve", try a more "frequent replenishing" to yield the longest battery life.

    Finally, avoid at nearly all costs allowing the battery to deplete so far that the phone powers down on its own. If the meter isn't in good calibration and you allow the phone to drain the battery to a self-powering off, you may find it becomes unresponsive to the charger and either exhibits a white light at the charge connection ("White light of death"), and doesn't take a charge at all, or that it tries to boot and after a few seconds fails, only to repeat in a never ending process until the battery is drained so low, it can't even respond to the power button. These symptoms or characteristics are perhaps not identical but will be similar across most, if not all phones now powered by Lithium Ion Polymer or Lithium Ion batteries.

    Thanks for all the info guys! I really appreciate it. Turns out my wife got me the Razr M as an early Xmas gift. Way cheaper than the Maxx HD, but the specs are mostly the same except for the screen, memory and battery. She used my sister-in-laws upgrade so I still have mine waiting in August. I was going to pay full price, but it works out WAY better this way. I have 1 more question since my phone is brand new and 1000% better and faster than the stratosphere I was using. Does it hurt your phone, or the battery, to keep it on the charger after it hit 100% full? I use it as my alarm clock, and just leave it charged all night. I would think that it would cut the charge off at least to a trickle after it's full. Am I right? This phone is incredible and I want to keep it in great working order. I'm not the guy that's gonna root it, (not yet at least), I just want to maintain battery life if I can. After all the advice, I will definitely start charging it when it hits around 20%, but I have 2 toddlers and they can really take up some time, so trying to remember to check my phone after it hits 100% will be pretty tough. Again, thanks for all the input guys! I'm really glad I found this place. And I'm really glad I decided to give Motorola a shot. I think I'll stick with them.

    P.S. - It was super cool getting the JB update RIGHT after I activated it, and it was even cooler knowing that a Factory reset was in order because of all the advice in the forum.
