[Z Fold 4 / Z Fold 5 / Z Fold 6]

194
00:09:30.276 --> 00:09:33.576
The Fold 4 displayed the most accurate red color

195
00:09:33.576 --> 00:09:35.776
But its sharpness was slightly lower

196
00:09:35.776 --> 00:09:38.076
Fold5 was the brightest once again

197
00:09:38.076 --> 00:09:41.626

00:10:19.576 --> 00:10:21.226
But the clarity was relatively low

213
00:10:21.226 --> 00:10:22.876
Colors are also slightly disappointing

214
00:10:22.876 --> 00:10:26.376
For Fold 5, it seems to have good clarity

215
00:10:26.376 --> 00:10:29.576
But there are areas where the color accuracy is off, with some greenish color

216
00:10:29.576 --> 00:10:32.326
Fold 6 captures with a clean tone

217
00:10:32.326 --> 00:10:35.276
And clearly defines the boundary between the subject and the wall

218
00:10:35.626 --> 00:10:40.776
[6. Basic outdoor shooting "landscape"]
Next, we also took photos outdoors

219
00:10:40.776 --> 00:10:43.276
Firstly, Fold 4 has vibrant bright colors

220
00:10:43.276 --> 00:10:46.026

00:11:05.976 --> 00:11:08.176
There are slight differences in color rendition

229
00:11:08.176 --> 00:11:11.026
[Overall vibrant colors]
Fold 4 seems to capture the blue tones well

230
00:11:11.026 --> 00:11:14.176
And also represents the green hues of the trees effectively

231
00:11:14.176 --> 00:11:16.776
[Sky and trees, with bright and vivid colors]
Fold 5 features overall bright vivid colors

232
00:11:16.776 --> 00:11:18.976
And effectively captures the feeling of sunlight

233
00:11:18.976 --> 00:11:22.426
[Somewhat murky colors]
Fold 6 has slightly darker and more murky color

234
00:11:22.426 --> 00:11:25.226

In bright conditions

280
00:13:28.076 --> 00:13:30.126
And appears to have minimal reflection

281
00:13:30.126 --> 00:13:33.876
I think the color expression is the brightest among the three models

282
00:13:34.226 --> 00:13:35.626
When watching the same video

283
00:13:35.626 --> 00:13:38.326
With the same settings in a bright outdoor environment

284
00:13:38.326 --> 00:13:40.576
All three products were comfortable to watch

285
00:13:40.576 --> 00:13:42.926
Still, there was an opinion that

286
00:13:42.926 --> 00:13:45.026
Fold 6 was slightly better in a bright environment

287
00:13:45.026 --> 00:13:49.576

293
00:14:03.626 --> 00:14:06.076
4,400mAh, which is the same

294
00:14:06.276 --> 00:14:09.726
What difference might there be when actually used?

295
00:14:09.926 --> 00:14:11.426
With all devices configured to the same settings

296
00:14:11.426 --> 00:14:14.426
We first ran games and the 3D MARK TEST

297
00:14:15.076 --> 00:14:18.826
Approximately 1 hour and 45 minutes used with gaming and testing

298

After an extra 3 hours and 10 minutes of use

304
00:14:41.476 --> 00:14:44.776
So far, the Fold 5's battery drain rate is relatively fast

305
00:14:45.226 --> 00:14:47.326
We continued to keep it running

306

The remaining battery is at this level

308
00:14:54.926 --> 00:14:58.226
Even now, the Fold 5 has the fastest battery drain rate

309
00:14:58.226 --> 00:15:00.426
While the Fold 6 still seems to have more battery life remaining

310
00:15:00.626 --> 00:15:04.276
Since there's not much battery left, let's continue watching 4K videos

311
00:15:05.176 --> 00:15:06.976
While watching the video

312
00:15:06.976 --> 00:15:12.876
[Total usage time of 13 hours and 53 minutes]
Z Fold4 was the first to run out of battery

313
00:15:12.876 --> 00:15:13.576
At this point

314
00:15:13.576 --> 00:15:17.376
[Z Fold4 0% / Z Fold5 4% / Z Fold6 19%]

[Z Fold4 0% / Z Fold5 discharged / Z Fold6 15%]
The remaining battery on Fold6 is at 15%

319
00:15:36.226 --> 00:15:39.326
The Fold 6 was the longest lasting

320
00:15:39.326 --> 00:15:41.826
Final results of the three Z Fold models

321
00:15:42.176 --> 00:15:44.176
Let's summarize the Fold series

00:15:51.526 --> 00:15:53.276
All devices surpassed 40°C

327
00:15:53.276 --> 00:15:55.876
But Fold6 exhibited slightly lower temperatures

328
00:15:55.876 --> 00:15:57.576
Also, when running apps simultaneously

329
00:15:57.576 --> 00:15:59.876
Fold4 was relatively slower compared to the other two devices

330
00:15:59.876 --> 00:16:01.926
While Fold 5 showed faster performance

331
00:16:01.926 --> 00:16:03.726
With more demanding apps

332
00:16:03.726 --> 00:16:05.676
Additionally, the Fold 6 had faster performance

333
00:16:05.676 --> 00:16:08.226
With lighter apps, including booting

334
00:16:08.226 --> 00:16:10.226
In the same environment and settings

335
00:16:10.226 --> 00:16:11.826
the difference was that

336
00:16:11.826 --> 00:16:13.776
Fold4 generally had a higher saturation

337
00:16:13.776 --> 00:16:15.226
With a more intense color palette

338
00:16:15.226 --> 00:16:17.676
However, when taking portraits and recording videos

339
00:16:17.676 --> 00:16:18.876
The results were disappointing

340
00:16:18.876 --> 00:16:21.376
Fold5 stood out with its vibrant and bright colors

341
00:16:21.376 --> 00:16:23.976
And it was strong and vivid when shooting indoors

342
00:16:23.976 --> 00:16:26.476
It provided the best results for portrait photography

343
00:16:26.476 --> 00:16:29.326
But there was a noticeable difference from the colors seen with the naked eye

344
00:16:29.326 --> 00:16:32.226
Fold 6 exhibited excellent sharpness

345
00:16:32.226 --> 00:16:35.326
And generally displayed clean and well organized colors

346
00:16:35.326 --> 00:16:37.926
The results in night mode were generally good

347
00:16:37.926 --> 00:16:41.726
There were instances of slight haziness depending on the conditions and setting

348
00:16:41.726 --> 00:16:44.576
For viewing in bright environments, the display brightness

349
00:16:44.576 --> 00:16:47.326
On Fold6 was the best among the three products

350
00:16:47.326 --> 00:16:50.526
Finally, the Fold6 also had the longest battery life

351
00:16:50.526 --> 00:16:53.326
Also take a look at the prices of each device
