Samsung Galaxy A02 battery review: Is the usage life on this smartphone really ‘terrible’ like 5,000 mAh?


After launching the smartphone market with high-end Galaxy S21 series products, Samsung did not forget to launch new products for the low-cost segment such as Galaxy M02s, Galaxy M12 and most recently Samsung Galaxy A02. This is considered one of the low-cost phones with ‘huge’ batteries at the moment. And let me evaluate the Samsung Galaxy A02 battery to see if ‘it’ really gives a long time of use.

Review Samsung Galaxy A02 battery based on familiar ‘difficult’ conditions

Samsung Galaxy A02 is equipped with a 5,000 mAh battery – a large capacity for a cheap phone is not it. So, when holding ’em it’ in my hand, I was quite excited about the battery test. Do you have any predictions for the useful life of this cheap smartphone using this 5,000 mAh battery. Please check with me to see if your prediction is correct or not!

How do you predict the battery life of the Samsung Galaxy A02?
How do you predict the battery life of the Samsung Galaxy A02?

Let’s take a look at a series of familiar conditions first!

  • Experience 4 rotating tasks including: Play Lien Quan, watch YouTube, surf Facebook and use Chrome.
  • Each task uses 1 hour.
  • Screen brightness: 100%.
  • Plug in wired headphones throughout.
  • Turn on WiFi and social media notifications.
  • Do not turn on battery saver, screen adaptive, GPS and Bluetooth.
  • Dot from 100% to 0%.

And the results I get after a period of testing under the above conditions are:

The results of TGDDĐ's
The results of TGDDĐ’s “hard” test has really made it difficult for the Samsung Galaxy A02.

Really from the beginning, I was expecting Samsung Galaxy A02 to last longer than 7 hours and 28 minutes. Although the battery life through the test results does not really satisfy me, it is clear that the 7 hours 28 minutes number is also ‘not the right kind’. I believe that with daily needs, the above battery can satisfy you for a long, comfortable day!

Evaluation of daily usage on Samsung Galaxy A02: 8 Korean episodes is a small thing!

After the ‘general’ test of Samsung Galaxy A02 with the four rotating tasks above, I also separate everyday applications and game apps into 2 parts to be able to bring more perspectives to you. I choose 5 applications that are used by the most daily people including: Chrome, YouTube, Facebook, Messenger, Zalo. And the test conditions for this time are not too complicated:

  • Screen brightness: 100%.
  • Plug in wired headphones throughout.
  • Turn on WiFi and social media notifications.
  • Do not turn on battery saver, screen adaptive, GPS and Bluetooth.

The results I got …

Test daily tasks on Samsung Galaxy A02
The results of testing everyday tasks on the Samsung Galaxy A02 are really not bad!
  • Chrome: 08 hours 09 minutes.
  • YouTube: 06 hours 48 minutes.
  • Facebook: 06 hours 44 minutes.
  • Messenger: 08 hours 14 minutes.
  • Zalo: 07 hours 13 minutes.

In general, for everyday tasks, the Samsung Galaxy A02 can provide quite a good use time, ranging from approximately 7 to more than 8 hours. That means, you can ‘plow’ 8 Korean episodes continuously without having to use the attached battery charger. You can also chat with friends for up to 8 hours via Messenger without worry. This is really not a bad number for a phone with a price of only about 2 and a half million, right!

One thing to note is that during daily tasks, when the Samsung Galaxy A02 is in full battery state, the experience is quite smooth. However, when the battery is reduced to about 20%, continuous lag starts. So I encourage you to always charge the battery fully for the best experience.

Review Galaxy A02 battery through the titles: Not too excellent but enough for entertainment!

As a cheap smartphone, the Samsung Galaxy A02 is not really a good choice for you to play games. So I do not have too much expectations on the time playing the game on ’em it’. I have tried 3 games, 2 of which are but the game is quite light but has a large number of players: Candy Crush and Angry Bird 2. The other game with a slightly heavier graphics level is Lien Military Mobile. Let’s go through the test conditions before coming to the results!

  • Screen brightness: 100%.
  • Plug in wired headphones throughout.
  • Turn on WiFi and social media notifications.
  • Do not turn on battery saver, screen adaptive, GPS and Bluetooth.
  • Turn on game configuration at its maximum.

The results you are expecting are:

Test results on Samsung Galaxy A02 game
Samsung Galaxy A02 is not really the ’em’ machine that can provide long-term gaming time.
  • Candy Crush: 6 hours 37 minutes.
  • Angry Bird 2: 5 hours 37 minutes.
  • Lien Quan Mobile: 5 hours 27 minutes.

As I expected, Samsung Galaxy A02 is not a specialized device for gaming, so although the battery has a pretty ‘huge’ capacity, it is clear that the time spent in games is not as good as when testing. with daily tasks. However, with that time, Samsung Galaxy A02 is just enough to help you have moments of light entertainment. Personally, ’em’, the above device will be suitable for users who are not too demanding on gaming!

However you can still enjoy gentle entertainment with 'em it'!
However, you can still have gentle entertainment with ’em it’.

In terms of gaming experience, Samsung Galaxy A02 can still ‘weigh’ well games with not too high graphics such as Candy Crush and Angry Bird. ‘Em’ on the device also gives higher battery life than the sub-game. Although I know that testing Lien Quan Mobile is quite a disadvantage with a cheap phone like Samsung Galaxy A02, but this is a ‘national’ game that everyone wants to experience on their device. And I am no exception.

The game Lien Quan Mobile will require a much higher level of graphics than the previous two games, so it can be seen that the playing time of this game is also the shortest. During the game, I also noticed that lag often occurs in intense combat, but this is what I think we have to accept with this cheap smartphone!

Samsung Galaxy A02 charging time: How long does a 5,000 mAh battery take to fully charge?

With a 5,000 mAh battery, Samsung is equipped with a 7.75W charger included. This is not a fast charger, so the charging time on the ‘younger brother’ I predict also lasts from 3 to 4 hours. If my prediction is correct, I feel that such a charging time is quite reasonable for a cheap device. Let’s see if I can check if it is correct or not!

Charging time
With just 1 hour and 30 minutes, you can fully recharge the battery half!

And it is true that the Samsung Galaxy A02 takes 3 hours and 08 minutes to fully charge the 5,000 mAh battery above, quite matching what I said above. If you use this smartphone as an attached device, this charging time is not too much of a problem. However, if you use ’em it’ as the main device, you will probably have to wait a relatively long time. But you can also rest assured that the Galaxy A02 battery can last for a long day, so the charging time can also fall at night, not too affecting the usage process!

summary

In general, the 5,000 mAh battery on the Samsung Galaxy A02 did not really meet my expectations, but honestly, the results of ‘her brother’ through the tests are also quite ‘stable’! Based on what has been shown, this smartphone will probably suit users who prioritize entertainment needs on social networks, YouTube, Chrome … rather than playing games. By the way, this smartphone is being exclusive in that Mobile World, so you can go to the nearest store to have a test and get yourself a device!
