Schematics and PCB review for TP5100 standard battery charger

[Sagar]

A basic charger IC, I want to use it in my portable power supply. TP5100 is unbalance 2s charger, is any way to make/ convert into balance charger. I made the schematics and PCB which I can use to charge, any design considerations please let me know.

See an example layout of a similar charger IC. TI's BQ25306:

The placement of the components is too messy.
The path to the inductor is too long.
Since it is switching, always be aware of the shortest possible length.

any design considerations please let me know

Why do you box everything into tiny sections which take significant effort to decode? Where does VBat come from, for instance? Literally, you could draw a straight connection from Vin to the chip, and  it would be immediately obvious that the thing on the left is connected to the thing on the right, and is only connected thus. No longer would you need to microscopically examine every label just to see if Vin happens to go somewhere else as well. (And it just so happens that now I noticed there are two Vin pins on the chip. See how easy it is to miss important stuff when you connect via labels?)

You can still have your boxes to say what each bit does ("This is the chip") but what the circuit actually does, the function of it, will be much more apparent and easier to read.

Now, you may say that the chip symbol doesn't really lend itself to that (it does in this case, but lets assume Vbat is on the left). That's because the symbol is showing the physical pin layout rather than the logical function. Inputs on the left, outputs on the right, group together related pins, etc.
