    Any idea of the life expectancy of the battery in a Razr Maxx??? Price to replace the battery??? How long does the replacement procedure take??? Send in to a repair center or take to a Verizon store?? , Considering a Razr Maxx but have questions!
    Thank you.

    Most li-ion batteries last for a few years. Most manufacturer warranties are 1 year. I'm sure its not too difficult to replace.

    Yes

    More than a pack of cigarettes but less than the cost to replace the battery in an iPhoneâ„¢


    7 mine and 12 seconds, but that's with a blindfold on


    You can do it yourself or send it in

    No, no - thank you

    Life expectancy of a battery of this type is measured in number of complete charge cycles before "end of life" or actual capacity versus original rated capacity in percentages. For instance, the battery in this phone is rated for 300-500 cycles where "end of life" is when the battery will only hold 80% of its original rated capacity, and where a cycle is the cumulative value of one full charge and then the same amount drained - or in other words it could be 2 - 50% charges each followed by the same amount discharged, or 3 - 33% charges or 4 -25% charges, etc. Whatever the number of cycles, it would still be considered "end of life" if it can no longer hold more than 80% of original rated capacity.

    Some manufacturers will deliberately limit the charge to less than 100% even though the meter may measure it as 100%, because charging to capacity actually shortens the battery's life (number of cycles). By limiting the charge to let's say 85% of capacity, it may actually give you 700-1000 cycles instead before the battery will only hold 80% of original rated capacity.

    Also, some manufacturers may consider 70% of original capacity or less as end of life, rather than 80%. It used to be considered that 50% of original capacity was end of life for rechargeable batteries when used in applications such as cameras or other devices, but that causes far too much complaints from phone users so the phone industry went to higher powered batteries and lower charge maximums to extend life and give longer run times.

    Likely in the range of $100 or so, possibly more since it's a bit involved.

    A good technician could accomplish a full replacement in 10 minutes or less.

    Most definitely a mail-in repair.

    One awesome phone, battery life out the whazoo, you're gonna love it!

    No problem. Happy to be of service. By the way, there will be less expensive options from smaller shops who will do it. You could also replace it yourself, there will be dealers who will sell then and will include the necessary tools, a torx wrench(probably T5, possibly also T3), and a spudger - essentially a pretty tool made of plastic or other molded material, designed not to cause scratching. There are videos as well as photo essays showing proper disassembly.
