    Just a few quick questions;

    What is your normal charging process, meaning do you charge frequently or once a day, and do you let the phone battery die or charge before?
    Have you practiced any "training" of the battery by either allowing it to drain fully, or trying to "bump" charge the phone?
    When charging, is the phone powered on or off?
    When charging is the phone still in the case, and if so what kind?
    When charging are you using the stock Motorola charger, a USB adapter to a computer, or a third party charger?
    When charging, have you noticed the phone getting excessively hot?
    Do you leave the phone in direct sunlight, such as on a dashboard of a car or truck for periods of time during the day?
    When using the phone, is it not only in the case, but also in a bag, pocket or briefcase and simply being accessed through the Bluetooth?

    Answers to these questions will help us ALL to identify and avoid any things we may think are normal, which could contribute to battery failures.

    Thanks.

    Remove the battery and trash it. Its integrity has been compromised. Lithium ion batteries can ignite or explode when this happens.

    I know this from years of experience crashing radio controlled planes and damaging batteries powered by this technology.

    DO NOT TAKE ANY CHANCES WITH A SWELLING BATTERY. CHUCK IT SAFELY AND GET A NEW ONE. AND ABOVE ALL, DO NOT TRY TO CHARGE IT.

    Floyd,

    I commend you on your comment. While I was in the military, I heard of this happening but never saw it happen. You have probably saved several smartphone users with this comment from serious injury. Yeh, yeh!

    1. I charge my phone for about 4 to 5 hrs at night. I work from 630am to 5pm. I always have to put it on a charger at work for about an hr at work as well to get me thru the day. I have never let the phone. If it get to low i shut the phone off.
    2. When i first got the phone i allowed it to die completely as i have always been told to do with new phones.
    3. The phone has always been on when charging.
    4. The phone has always been in a case since i have gotten it in November. Only have taken it out a few times to clean the dust and dirt out from between the phone and the case. I am using the VZW shell/holster combo with kickstand.
    5. I am using the stock charger that came the phone. And i have a VZW duel car charger. My work uses all Verizon phones for their drivers so when charging the phone at work i am also using VZW wall chargers.
    6. There has been a few times while the phone is charging that i have noticed that the phone has gotten really hot. I pulled it off the charger and let it cool down every time i noticed it.
    7. I never leave the phone in direct sunlight. If i do leave it in my work truck or in my car for any reason then i make sure it is a shaded part of that vehicle.
    8. I dont use Bluetooths (cant stand them) so the phone is always in its case when im using it. I do however have the car dock in my car for this phone. I do use that for time to time..


    I hope these answers help everyone.

    First off, we haven't even determined conclusively if the battery has swelled as suspected. I can pop open the corner the OP is referring to on my phone with my thumb nail and it will stay open unless I snap it shut again. With a slight twisting motion I can do the same thing.

    As far as removing the battery and disposing of it, that is best left to the experts. If the battery is suspected of having swelled, and the case will not remain shut if snapped together again, then the phone should be returned to a Verizon Phone Center Store, NOT an authorized Verizon dealer for replacement.

    • Great, this is what the manufacturer has expected most people to do, and has designed the charging circuitry to handle this type of varying charge length and frequency.
    2. When i first got the phone i allowed it to die completely as i have always been told to do with new phones.
    • This unfortunately is a carryover from the "old days" of Nickel Cadmium (NiCd) batteries, which had a problem known as "memory", and isn't even the proper procedure for NiCd batteries either. There is NO benefit whatsoever to draining a brand new NiCd OR Lithium Ion/Lithium Ion Polymer (LI or LIPO) battery to its cutoff level for the device, and in the case of NiCd batteries would only be beneficial if the battery had begun to develop the "memory", usually after months of improper use/charging procedures.
    • This "memory" would only be an issue with NiCd batteries if someone had been routinely using less than a full charge (i.e. 50%), and then fully charging over many cycles. Eventually the battery would take on a capacity for charge that would be about 50% and the device would begin to run out of charge half-way through the expected capacity. By draining fully and then charging through several cycles, you could "push" the capacity back to near what it was originally.
    3. The phone has always been on when charging.
    • Although this isn't necessarily considered "improper", it is known that the battery may not actually receive a full "100%" capacity charge while the phone is on since by using power the phone can confuse the charging circuitry into thinking it has identified a signature drop in current draw which it is looking for to signal the last phase of charging, and as a result will mistakenly reduce the rate of charge to "top off" the battery but will not actually saturate the battery. This can cause the battery to actually have somewhere on the order of 85%-90% charge level even after the "100%" charge indicator appears signaling a complete charge.
    • Since LI/LIPO batteries MUST be removed from charge once they have reached their capacity (or near capacity) to prevent stressing of the battery, thereby shortening it's useful life and possibly risking catastrophic failure, the circuitry shuts down charging (you may notice NO lightening bolt on the battery indicator even when plugged in after a period of time). As a result, what you believe to be a fully charged battery may not provide power for as long as you would expect.
    • In order to assure a full charge, you should power down the phone BEFORE plugging in, and allow the Charge Only mode to charge the battery to 100%. You may wish to do this once every few days or so to assure you are getting the best possible results from your phone, and to reset the battery's meter to properly display relative remaining capacity.
    4. The phone has always been in a case since i have gotten it in November. Only have taken it out a few times to clean the dust and dirt out from between the phone and the case. I am using the VZW shell/holster combo with kickstand.
    • Although it may not be a big problem charging while in the case, the heat generated both while charging and also while using can't escape as easily and so the temperature of the battery may rise above what is considered acceptable ranges (typically below 113F). Heat is your battery's worst enemy. If the battery remains above 113F for any extended periods of time it accelerates the battery's aging process (much the same as with just about anything else). If it has been charged in this manner repeatedly over many cycles, the effect may also cause the battery to produce excess gasses which can cause the battery to swell.
    5. I am using the stock charger that came the phone. And i have a VZW duel car charger. My work uses all Verizon phones for their drivers so when charging the phone at work i am also using VZW wall chargers.
    • Good news. Using ONLY approved chargers or the USB ports on computers (which have highly regulated power supplies), or portable "battery boosters" which are powered by batteries will prevent any damage to the battery.
    6. There has been a few times while the phone is charging that i have noticed that the phone has gotten really hot. I pulled it off the charger and let it cool down every time i noticed it.
    • As described above, this is bad for this type of battery. The fact that it has happened at times and you noticed it, leads someone to suggest it could also have happened at other times when you didn't notice it, such as during the nighttime sleeping charge cycles. This could contribute to shortening of the battery's lifespan and may also contribute to generation of excess gasses which can cause the battery to swell.
    7. I never leave the phone in direct sunlight. If i do leave it in my work truck or in my car for any reason then i make sure it is a shaded part of that vehicle.
    • The temperature inside a car can rise VERY quickly and reach deadly temperatures, even with all 4 windows cracked. The charts below show outside temperatures and comparison of inside a car, first with all 4 windows closed, then with all 4 windows cracked. The charts stop at 12:00 noon and 1:00pm since these studies were done in a climate where outdoor temperatures reached well above 100F, so using 101F as a max temperature results in cutoff at those times. The heading "Indoor/Outdoor" is to identify the type of thermometer used, simply for relative accuracy measures. Also, even if the temperature outdoors doesn't continue to climb the temperatures inside the car can still climb several degrees more.

    • With summertime coming, this is something we all should be aware of and try to avoid.
    8. I dont use Bluetooths (cant stand them) so the phone is always in its case when im using it. I do however have the car dock in my car for this phone. I do use that for time to time..
    • The car dock, being BLACK, gets very hot since it is typically attached to the windshield glass via suction cup. With the phone in a case, and then the entire phone and case in the dock, it's actually like placing the phone in an oven inside a pot, where the pot prevents heat from escaping around the phone, and the oven prevents the pot from allowing thermal conductive cooling or worse.
    I am only giving these evaluations for the benefit of everyone with a phone who has a Lithium based battery. There may be naysayers who step in to dispute my comments but nearly all of what I say here is backed by scientific studies (including the car temperatures), and most of the battery specific information comes almost verbatim from one of the most well-respected battery analyzer manufacturers in the world, and a great resource for information regarding batteries in general, www.batteryuniversity.com which is maintained by Cadex, Inc.


    To the OP, if your back of the phone is visibly swelled, or if when you snap that corner back down it immediately pops back open, I suggest you do have battery damage. In your case, you've already contacted Verizon and they are sending a replacement, so the point is moot for you, however if this type of situation develops for anyone else, as Floyd above says, first DO NOT charge the battery any more. Some RC enthusiasts will tell you that even slightly puffed up batteries can be used but they are far more careful about how they charge their batteries than we are, and they're not going to be putting those batteries in their pockets or near their faces.

    Second, make sure the phone is placed somewhere that is not a risk for fire, such as a concrete step or patio. Third, take the phone to a Phone Center Store as soon as possible, and depending on how severe the bulging, you may want to place the phone inside a metal container during transport for added protection. Forth, if the battery discharges any gasses, DO NOT breate them in, move the phone quickly to a non-flamable area or metal container and take outside immediately, and ventilate the area where the gasses were first discharged.

    I have always considered battery swelling to be due to overcharge but I thought this was not possible on modern devices/chargers?
