First off, a battery is an assembly of cells to give the desired capacity. Most cell phones now available have a single Lithium Cell. (That's different to the Cell in cellular phone.) So, no battery any more. The grammar police can do what they want with that.
"Fully Charged" is a bit of a variable, just like "Fully Discharged". It used to have a meaning, but now the meaning depends on who you are talking to. When your phone advises that it is fully charged, it means the manufacturer has decided that what you've got is all they want you to have. If you charge a LiPo battery to the maximum it can hold, it will quietly (hopefully) start damaging itself The internal connections of some batteries will start transferring by electroplating from where they were designed to be to where they short out areas of the electrodes. No good for the leads, definitely not good for the electrodes and possibly rather inflammatory for your lithium cell and / or your pocket.
When the marketing division of the manufacturer is the sole arbiter of the phone specification it is likely that they will quote a cell capacity that is bigger than the opposition claims for theirs. Thus, the specifications tend to rise above reality as the price point goes down. Reputable manufacturers have a tendency to be quite conservative as far as specifications go. They are also conservative on the settings for the charge/discharge controller and so the setting for "Fully charged" is set with more priority given to the cell lifetime performance, this is allied to a higher grade of cell (dearer) than the more bargain priced units use.
Basically, a high end phone has a better cell, more conservatively operated for enhanced safety and durability. The more bargain priced phones are optimised for marketing impressions. A good phone looks after your lithium cell rather carefully regardless of what you do. For bargain phones, you have to determine the charge / discharge conditions to give the result you desire. This is not always easy, or even possible especially given the supplied charger is likely optimised for production cost to be as cheap as possible while not being unacceptably dangerous or harmful to the low-cost cell used..
Kindness to your cell charging routines can be very helpful to "economy" phones, and not at all harmful to flagship phones.
Slower charging is always better than fast, but by how much is variable.
