A Time I Got Lost

Or "A Time I Was Lost." "A time I lost" would be used for when you lose a game or contest.

Nowadays, most of us use smartphone apps to assisthelp us navigate in new places.

If you want to use "assist" you could say "to assist us in navigation in new places." "Help us navigate" feels more natural.

In most cases, at least in cities, we really do not need to worry anymore about getting lost in a fresh city.

"New city" might be a little more natural than "fresh city."

I remember a time about five years ago when I first time visited Oosaka in Japan.

One day at about 9 o'clock in the evening, it was dark. and

I would connect this with the following sentence.

I was walking to my hotel with my 10-year-old daughter, andwhen suddenly my phone was suddenly out of power.

You can also say more familiarly "my phone died."

Unfortunately, my mobile charger was also without any preserved electricitymaining charge.

I felt a bit panicky; I only knew that the hotel was nearby to me about two kilometers away.

She also didn't knowwasn't familiar with the hotel, however, the kind lady didn't show any hesitation and used her own phone to find the route for us.

Finally, we arrived at the hotel in 10 minutes.

A suggestion: "Once we knew the way, it only took us 10 minutes to get back to the hotel!"

From my experience of the time I got lost for a while, I fouind more and more people actually don't remember the accurate address or they have no sense of direction for places, w. We rely on smartphones heavily.

A Time I Got Lost

The expression is "to get lost".

Nowadays, most of us use smartphone apps to assist usour navigateion in new places.

Think this sounds more natural.

In most cases, at least in cities, we really nodon't need to worry anymore about getting lost in a freshnew city.

"city" is at the end you don't really need it twice. Negative of a simple tense uses the auxiliary verb do. I need -> I don't need.
"anymore" - ie at any time. As above "to get lost". "fresh" does not really work here although the words can have similar meanings.

I remember about five years ago when I first time visited Oosaka in Japan.

"when I first visited" or "the first time I visited". In English the city in normally written Osaka, although it is not an exact an exact match to the romaji.

Unfortunately, my mobile charger was also without any preserved electricitydidn't have any stored charge either.

"stored charge" rather than "preserved electricity".

I felt a bit panicky; I only knew the hotel was near to me about two kilometers afrom where I ways.

X distance from location
Note: in British English it's kilometres but it is okay as is in American English.

First I comforted my daughter first, then asked for help from a woman passing bya female passer-by for help .

Sounds better with "First" first. :) Someone "passing by" is a "passer-by".

She also didn't know the hotel, h either. However, the kind lady didn't show any hesitation and used her own phone to find the route for us.

FinallyIn the end, we arrived at the hotel within 10 minutes.

"in the end" i.e. At the conclusion of the story. "within 10 minutes" sounds better. Arrived less than 10 minutes after asking directions.

From my experience of the time I got lost for a while, I found more and more people don't actually don't remember thean accurate address or have no sense of direction for places,, instead we rely on smartphones heavily.

again "to get lost" = got is past tense of get. Put actually between don't and remember it sounds more natural. I would say "an accurate address" as you are talking about an address in general not a specific address. Don't need "for places" it sounds find with just "no sense of direction". Use "instead" offers an alternative to what you do rather than remembering addresses or knowing where you are.
