خواهرم گفت که باتری گوشی اش هم زود تمام میشود و باید آن را شارژ کند.

خواهرم means my sister.

It is made of:

• خواهر = sister
• -م = my

So instead of saying a separate word for my, Persian often attaches a pronoun ending to the noun.

Other examples:

• برادرم = my brother
• دوستم = my friend

In Persian, the verb often shows enough information by itself, and the subject can be omitted if it is already clear from context.

So:

• خواهرم گفت = My sister said
• literally: my-sister said

You do not need a separate او (she) here, because خواهرم already tells us who did the action.

که means that and introduces a clause.

So:

• خواهرم گفت که ...
• My sister said that ...

In English, that is sometimes optional:

• My sister said that...
• My sister said...

In Persian, که is very commonly used in sentences like this.

باتری گوشی اش means her phone’s battery or the battery of her phone.

It breaks down like this:

• باتری = battery
• گوشی = phone / mobile phone
• اش = his / her

So the phrase literally works like:

• battery [of] phone her

A more carefully written version is often:

• باتری گوشی‌اش

with a half-space before اش.

اش is an attached pronoun meaning his / her / its.

In this sentence:

• گوشی‌اش = her phone / his phone

Persian does not distinguish his and her in this form. The context tells you which one is meant.

So because the sentence starts with خواهرم (my sister), we understand گوشی‌اش as her phone.

هم means also, too, or as well.

In this sentence:

• باتری گوشی اش هم زود تمام میشود
• Her phone battery also runs out quickly

The idea is that this is true too, probably in addition to something mentioned earlier.

Its position can feel flexible in Persian, but here it attaches naturally to the whole noun phrase before the rest of the statement.

Literally, it means:

• زود = soon / quickly
• تمام میشود = becomes finished / gets used up / runs out

So for a battery, زود تمام میشود is a natural way to say:

• it runs out quickly
• it dies quickly
• it doesn’t last long

Persian often uses تمام شدن (to be finished / to run out) for things like battery, money, time, food, etc.

Yes. میشود and می‌شود are the same word; the second spelling is more standard.

Here:

• می‌شود = it becomes / it gets / it is
• in this context: it runs out / gets used up

So:

• تمام می‌شود = it gets finished / it runs out

In everyday writing, people often write:

• میشه for می‌شود
• میشود without the half-space

All of these are related forms, with different levels of formality or spelling precision.

After باید (must / should / have to), Persian normally uses the subjunctive form of the verb.

So:

• باید ... شارژ کند = she must charge ...
• not باید ... شارژ می‌کند

Here:

• کند is the subjunctive form of کردن for he/she

This is a very important pattern in Persian:

• باید بروم = I must go
• باید بخواند = he/she must read
• باید شارژ کند = he/she must charge

آن را means it as a definite direct object.

Breaking it down:

• آن = that / it
• را = object marker

So:

• آن را شارژ کند = charge it

The را marks آن as the object of the verb.

In natural English we just say charge it, but Persian often makes the object relationship more explicit with را.

In conversation, you may also hear:

• اونو شارژ کنه which is a more colloquial version of آن را شارژ کند.

Yes, in a way.

شارژ is a borrowed noun from charge, and Persian commonly combines such words with کردن (to do) to make verbs.

So:

• شارژ کردن = to charge
• literally: to do charging

Then:

• شارژ کند = he/she charge(s) in the subjunctive, as required after باید

This noun + کردن pattern is extremely common in Persian.

Other examples:

• تمیز کردن = to clean
• کنترل کردن = to control/check
• تعمیر کردن = to repair

Here, گوشی means mobile phone / cell phone.

In modern everyday Persian, گوشی very often means phone, especially a mobile phone.

Originally, the word can have other meanings in other contexts, but in everyday speech:

• گوشی = phone
• گوشی موبایل = mobile phone

So باتری گوشی naturally means phone battery.

The sentence is perfectly normal and understandable, and it leans toward standard written Persian.

A few things make it look more written:

• آن را
• می‌شود / میشود
• full forms like شارژ کند

In everyday speech, someone might say something like:

• خواهرم گفت که باتری گوشیش هم زود تموم می‌شه و باید شارژش کنه.

This spoken version uses:

• گوشیش instead of گوشی‌اش
• تموم می‌شه instead of تمام می‌شود
• شارژش کنه instead of آن را شارژ کند

Both versions are correct; one is just more conversational.

Grammatically, the nearest logical reference is باتری (the battery), so آن را شارژ کند most directly means charge the battery.

But in real-life English, we usually say charge the phone, while Persian may still talk about the battery more directly.

So the idea is:

• her phone battery runs out quickly and she has to charge it

In practice, the meaning is completely natural even if English and Persian package the idea a little differently.
