    So i have been listening to audiobooks all day and thus need to recharge my battery often (my phone is old). I read on the web that for the battery to reach it's highest lifespan i need to maintain the charge at 50-80%.

    What would be the best method to reduce wear on my battery:
    a) Charge every time the charge hits 50% (and charge the phone twice a day)
    b) Charge it when it hits 10-20% (Only one charge every 1-2 days)
    ?

    And if this is the wrong forum for such a question, i'm sorry. I'm new here.

    Generally a) is better than b), you're better off charging your battery more than less each day. Running the battery down to 10% actually decreases the battery's overall longevity. Not something to worry about if it happens occasionally but not a good idea to do it regularly.
    If it's not always convenient to have your phone's power adapter handy, maybe think about getting an external battery:

    there is no consensus on this issue.
    The tests were not carried out, and without tests is not possible to know exactly.
    All agree on the issue that the complete discharge of harmful for the lithium-ion battery, so it is not recommended to keep it on the brink.

    But the old battery did not recover, can only extend the life of the new.

    Actually there is. ;)

    All li-ion batteries have a finite lifetime of charge cycles i.e. 0-100% due to their chemistry. That's why "little and often" is usually cited as the answer to "how should I charge my phone?"

    A good explanation, with illustrations of how various conditions affect li-ion cells, can be found here.

    There is a common consensus is that if your buy a phone with non removable battery, whatever you do as charging method, you will have to change your phone every 2 years of regular use.

    That might have been the consensus at one time but things have progressed quite a bit. Currently, there are countless older phones still in use that are over 2 years old, still powered by their original batteries, irregardless if they are or are not user replaceable. In reality, smartphone batteries typically have a useful life much longer than two years. My S3, a four year old phone, is still powered by its original battery. An anecdotal example but not out of the ordinary.

    Of course the battery is not dead, but it's weakened and won't be able to get you through the day as it's supposed to.

    It doesn't make sense to continue using a device that can't last reasonably. My Nexus 7 (2012) still works on its original battery but it lasts merely 2 hours instead of 6 hours before.

    As mentioned in the link above, depth-of-discharge and charging voltage can make a big difference. My Sony Xperia Z was 31 months old, with the original built-in battery showing no signs of fading, when it was replaced due to physical damage.

    I'm using a 3.5 year old phone with a non-replaceable battery. Doesn't last as long as it did when new, but still gets through the day. So if there is such a consensus, it's wrong ;).
