Battery capacity is one of the most significantly upgraded elements on the Galaxy S10 + compared to the previous S9 + generation. In addition, this is also the first Samsung smartphone equipped with wireless reverse charging feature, allowing convenient energy sharing with compatible phones and accessories when needed.

In terms of specs, Galaxy S10 + uses 4,100 mAh battery, greater than 600 mAh compared to the S9 + and 100 mAh generations compared to the Note 9, which belongs to the top flagship smartphones with the largest battery capacity today.

Galaxy S10 + is Samsung's largest battery-powered smartphone, currently in S series and Note

Besides the battery, Galaxy S10 + also upgraded on performance power with eight-core Exynos 9820 processor (2 Mongoose M4 cores at 2.73GHz, 2 Cortex-A75 cores clocked at 2.31GHz and 4 Cortex-A55 cores at speed). 1.95Ghz), Mali-G76 MP12 GPU and produced on 8nm process.

In the standard version, the S10 + has 8GB of RAM, 128GB internal memory, glass back, while the ceramic back still has 8GB of RAM, but internal memory is 512GB. Notably, the S10 + also has the highest configuration version with up to 12GB of RAM and 1TB of internal memory.

The remaining parameters are the same in all versions: the screen "Mole" Dynamic AMOLED 6.4 inch 3.040×1440 pixel resolution (pixel density 522 PPI), 19: 9 ratio, 3 rear cameras 12MP + 12MP + 16MP, 8MP + 10MP dual front camera and Android 9 operating system One UI interface.

To test the battery of Galaxy S10 +, we use standard battery reviews of VnReview based on 3 common activities in practice including playing games, surfing the web and watching movies. In addition, we also use daily devices such as the main device and monitor the amount of battery consumed when screen brightness and standby mode using AccuBattery Pro application to assess battery life in real time.

Standard tests: watching movies, surfing the web and games

The standard battery reviews of VnReview are done with general assessment conditions including 70% screen brightness, 70% volume, headset plug-in, turn on WiFi connection and calculate the time from full 100 % battery until 10% battery is stopped.

Time to watch movies continuously from full battery to 10%, brightness and volume at 70%.

With the movie review, Continuous repeaters an offline movie saved in the phone's internal memory with MX Player software. The total time for watching movies that Galaxy S10 + is reached is 13h51 minutes, at a good level, slightly higher than Galaxy S9 + (13:30) and iPhone XS Max (13h36) but not as impressive as Galaxy Note 9 (18h37).

Time to surf the web on Wi-Fi network at screen brightness of 70%, the battery life from 100% to 10% will stop.

In the web-time review, We use a simulated application to open web pages and drag the screen regularly just like a user is reading a real web. Websites that are rated include popular news pages. The Galaxy S10 + result is 9h47 minutes, continues at a good level, better than Galaxy S9 + (9h10) and iPhone equivalent Max Max (9:47 am) but still has a lot of effort to catch up "brother" Note 9 (10h54) .

Play the simulator on the GFX Bench software with a screen brightness of about 70% from the time the battery is full until 10% stops.

Finally, the game review This is done by running the GFX Bench software continuously in the battery test "Battery Test T-Rex", the screen brightness is 70%. This is a test of smartphone hardware because of heavy graphics. In this test, smartphones often run hot and consume more battery power than the actual heavy game play.

S10 + still shows good results with a time of 4h27 minutes, higher than S9 + (3h45) but much less than Note 9 (5h36) and iPhone XS Max (5h51). Repeating this heavy test repeatedly to measure the battery also caused Galaxy S10 + to heat up but not to the point of being uncomfortable. According to Samsung, S10 + continues to be equipped with steam chamber heat pipe system.

Actual use

When using the device as a main device to install both SIMs, we also repeat our daily activities: web surfing, social networking, chat and game play, WiFi connection in most of the time and when Out using 4G connection. With one battery charge, high usage intensity when constantly checking Facebook, watching YouTube, chatting Messenger, listening to music, playing games, turning on GPS, Bluetooth continuously to use Google Maps, connecting to Galaxy Buds headphones and bangles Mi Band 3 hand, I can use the machine for about 1 day from 8am to 10pm with a total screen time of about 6.5 hours.

In addition, the S10 + also has Night Mode to allow the entire interface to be switched to dark style (Dark Mode) while reducing eyestrain when using the camera during the night, while saving battery a little due to the characteristics of the screen. AMOLED will use less energy when displaying black because it can turn off pixels completely.

Actual battery life of Galaxy S10 + according to AccuBattery Pro application.

As reported by AccuBattery Pro application based on 1 week of use, Galaxy S10 + consumes an average of 15.2% battery at every hour of screen (onscreen) and 2.4% per hour of idle standby ( Turn on Always On Display from 6am to 12pm.

Charging time

Galaxy S10 + continues to support only fast charging standard Adaptive Fast Charging 15W from time … S5, similar Galaxy S7 / S8 / S9. This is Samsung's own fast charging standard, compatible with Qualcomm's Quick Charge 2.0 standard. In addition, it can charge a 15W Fast Wireless Charging 2.0 wireless charger via the included Samsung wireless charging dock or use the Qi standard wireless charging dock from other vendors.

The Galaxy S10 + charger comes with 9V – 1.67A or 5V – 2A output

With the 15W quick charger attached, Galaxy S10 + takes a total of 1 hour 49 minutes to fully charge the 4100 mAh battery of the device. In it, the first 30 minutes of charging up 35% of the battery and 1 hour of charging 70% of the battery.

Unfortunately, we do not have a 15W Fast Wireless Charging 2.0 wireless charger to check the wireless charging speed of S10 +. However, when trying a third-party wireless charger, the Choetech T535-S, 10W, the S10 + still receives a fast wireless charger and takes about 3 hours to fully charge, of which the first 30 minutes charge 10%.

The S10 + still allows for fast wireless charging with 10W wireless chargers

A new feature of the wireless charging capability of the S10 + is that the phone has a wireless reverse charger to share batteries with compatible devices such as phones, smartwatch, headsets … Qi standard wireless charging support. This is the first feature that appeared on the Huawei Mate 20 Pro, but not really popular because the usage is complicated, users have to go deep into the battery settings to activate.

Wireless Power Share wireless charging sharing feature first appeared on a Samsung smartphone

With the S10 +, wireless charging is more accessible. Just turn on the Wireless Power Share feature from the notification bar, then back the S10 + with the device you need to charge. Note that when the battery is below 30%, the wireless battery sharing feature on the S10 + will not work. Of course, the S10 +'s wireless reverse charging speed is only average, suitable for charging small devices like Galaxy Buds headsets. Or you can use this feature to charge overnight, when just one cable can charge S10 + and wireless "power transmission" for the Galaxy Watch or even … iPhone X. Medium, S10 + takes about 25% of the battery every hour when using Wireless Wireless Power charging feature.

Or you can "emergency" while needing for any other smartphone compatible with Qi charging standard


With the results in standard battery reviews of VnReview and practical use, we can see Galaxy S10 + is one of the few high-end smartphones with good battery life today. The device can meet 1 day of comfortable use with high intensity, 4G, Bluetooth, GPS turn on continuously. Wireless charging feature is quite interesting and useful when it comes to sharing batteries with accessories such as headsets, smartwatch, smartband or other compatible smartphones.

The problem that needs to be improved most on the S10 + battery is fast charging speed. While some rivals from China such as Huawei, Oppo, One Plus have gone very far with fast charging technologies 40W – 50W, fully charged 4200 mAh battery takes just over 1 hour, 30 minutes is full of 70% battery then Samsung is still just "stalling" with fast 15W charging technology.
