    Hi,
    I am on my fourth Droid 4 in three years. The last two have had a problem with the battery swelling (enough to push the back cover out.) It does get warm. The last one wasn't a year old yet. I read somewhere that playing games can cause the battery to swell. I do play poker or crossword puzzles for a couple of hours a day. Can that possibly cause the battery to swell?
    Thanks,
    Don

    If the battery is swelling I would stop using it immediately and call Verizon to ask for another replacement. You wouldn't want to be playing poker and have that thing explode in your hands.

    Nothing less than a short should be causing the battery to swell. Any swelling at all is bad and should be replaced asap.

    Don, no apps can be held responsible for a battery swelling...as mountainbikermark said, in respect to consumption of power only a short or near short can create the massive power consumption necessary to swell a battery. There are other potential causes of batteries swelling;

    1) If the battery is charged at too high a current rate (not likely since the chargers aren't putting out anywhere near enough to be the cause),
    2) If the battery is over-charged (also not likely since the charging circuit in the phone limits the battery voltage),
    3) and deep-discharging (which IS a possibility if the meter has fallen out of sync with the battery and telling the phone it has power left in the battery when it's actually fully discharged).

    In any case I agree 100% with dezymond...a battery that's swelling is a battery that's potentially a very serious hazard and should be discontinued from use immediately and disposed of properly. Do NOT keep the battery in the house, car, boat, plane...anywhere that is enclosed. Take the battery outside, leave it on Cement until which time you can drop it off at a hazardous waste facility.

    You forgot #4. Made In China. Quality control within the cells themselves are a crap shoot with Chinese batteries.

    You're right... Poor quality in craftsmanship and inferior materials can contribute to a higher than normal percentage of defective cells which can subsequently lead to early failure and dangerous consequences

    Hi again,
    Thanks to all for the prompt replies. The battery in the Droid 4 is not removable so when it gets fat I call Verizon and they send me another. Even with the Cloud and other backups I'm getting tired of reloading info into the phone. It's always on the Verizon charger if I'm not using it so I can only "assume" it's not over charging. The romance is fading with Droid. I used to be able to set the phone to "never sleep." now the longest setting is 10 minutes.
    Thanks again,
    Don

    The reason why your batteries are failing is because you have it on the charger all the time.

    if its "always on the charger when im not using it", that constant cycling is whats likely causing the battery to swell.
    im sure FoxKat will insert a technical explanation for this later :)

    Actually yes, that is over charging it.

    Yes, they're both correct - topping off of the battery does accelerate the aging process, and will dramatically shorten the battery's life. Since swelling is a common part of the aging process, swelling would occur sooner as well.

    The less time the battery sits between 90% & 100%, as well as between 10% & 0% the longer it will last. If you push those ranges even farther, (80% to 100% & 20% to 0%), you'll increase the battery's lifespan up to 4-fold or better.

    So charging between say 20%-80% is the ideal range to get the longest overall battery life? It's early for me right now, my brain is still waking up:p
