As everyone knows, current smartphones are powered by rechargeable batteries that provide a certain time of usage to our phones, and sadly there hasn’t been manufacturer able of finding the holy grail of technology that allows us to use a device indefinitely. However, we are not here to talk about fantasy (or science fiction for the matter) and personal wishes, we are here to talk about facts, for such reason we’ll be comparing the OnePlus 3 with the Samsung Galaxy S7 and the Xiaomi Mi5 regarding battery, the length and especially how much time they take to be fully charged again.Battery comparison general

Each smartphone represents the flagship of its respective brand or at least one of their most remarkable devices until the present day. We’ll be taking into consideration the Chipset and display since these are the biggest factors that influence the battery alongside the OS and the optimization provided by the manufacturer. But let’s not waste more time and let’s get right into these devices.

OnePlus 3 Battery

The OnePlus 3 was released not so long ago, it features a powerful Snapdragon 820 CPU and a 5.5-inch super AMOLED screen that supports a resolution 1080p. It runs on Android 6.0.1, but this isn’t the most decisive factor when it comes to battery.

The smartphone is powered by a non-removable 3,000 mAh battery that is meant to last an entire day before needing a recharge. OnePlus stated on several occasions that their goal is to provide a single day of continuous usage. Afterward, you’ll be forced to use the charger. The stamina of the battery is ok for a device like this, which on this aspect isn’t precisely surprising in our humble opinion, but neither bad.

According to the manufacturer, the OnePlus 3 battery can provide over 7 hours of continuous video playback on a 2k resolution, but in our experience, you won’t be able of surpassing 6 hours if you decide to do this. If you are a gamer you would probably want to know for how long you can perform gaming activities on this terminal, well, the OnePlus 3 battery has shown that it can deliver up to 4 hours of continuous gaming. Games such as Real Racing 3 and Modern Combat 4 have seen the battery level drop by 12% in approximately 15 minutes, which is a pretty decent mark when you consider how demanding these games are.

Of course, all these measurements can widely change according to the settings used since we are assuming that you would have the brightness to the maximum and the Battery Saver mode disabled. And talking a little bit of the saving mode, it can stretch up the life of the OnePlus 3 battery for around an hour when is activated. However, this will reduce the device’s performance and decrease background services alongside the vibration.

Now, with all that in mind, the OnePlus 3 SoC features Quick Charge 3.0technology alongside the manufacturer’s own offer, and its name is Dash Charge. This last feature comes to save the day of a product that otherwise would lack reliability. The Dash Charge is a fast charge feature that gets the smartphone from 0 to 95% of charge in almost an hour. In only 30 minutes the device can regain up to 60% of its charge. Another huge aspect is that the performance is not throttled down while is charging, meaning that you can continue your activities normally.

However, a different charger is required in order to use this feature. This is a 5V, 4A charge block that uses a USB-C cable instead of the usual micro-USB. Luckily for us, all those items come included with the phone. It’s also worth to mention that you can use a regular USB-C cable, but the charge time would be increased significantly.

Samsung Galaxy S7 Battery

The Samsung Galaxy S7 features an Exynos 8890 processor with eight cores and a 5.1-inch QHD panel that supports a 2560 x 1440 resolution and uses Samsung’s Super AMOLED technology like the S6. This device runs on Android 6.0.1Marshmallow and supports wireless charge.

The Samsung Galaxy S7 battery has a 3,000 mAh capacity and according to Samsung itself, the duration is up to a day and a half. Nevertheless, this isn’t 100% truth since it means to regulate the usage of the device, and let’s be honest with ourselves, if you are going to spend hundreds of dollars on a smartphone you better use it. Therefore, the real lifespan is around 24 hours or even a day and a half if you don’t push the device too much and limit yourself to basic activities. Most users will find themselves with 10 or 15 % battery left and the end of the day.

The worst enemy of the Samsung Galaxy S7 battery is the AMOLED display, which like you can imagine, it will deplete the battery very fast while doing heavy use of it. For instance, a long session of gaming and video streaming showed that in around 5 hours the battery will have approximately 15% charge remaining. Although, we consider that this a good sign when you compare it to its predecessor.

The Samsung Galaxy S7 features a couple options for saving battery, the standard method can extend the life up to 45 minutes when only 5% of the battery is left, but then again, this will considerably reduce the performance, the background services, and vibration feedback. If you are really desperate, and your life depends on having your smartphone turn on, then you can launch the Samsung’s ultra-power-saving mode, which will leave you with a greyscale theme and will restrict the apps usage to those previously selected by you. It will also turn off the Mobile data when the screen is locked, but it can provide up to 1 hour and 45 minutes of additional usage with only 5% of remaining battery.

Samsung Galaxy S7 Battery: charge time

Last but not least, we have the charging times, which are fairly decent on the S7. Thanks to the fast charge feature the device can regain 25% of the battery in only 15 minutes, in 35 minutes you can have 50% of the battery back. All of this while charging the battery from zero. However, after 50% of the battery is recharged the process won’t be that fast, but definitely not slow. In 1 hour and 15 minutes, the Samsung Galaxy S7 battery should be fully charged again. It’s worth mentioning that the version from North America is powered by a Snapdragon 820 processor, and took around an hour and a half to be fully charged. Therefore, we have a slight difference that we will definitely remember and so should you.

It’s mandatory to remark that the wireless charger feature takes more time to deliver a fully charged battery, even the most expensive devices take 120 minutesin order to get the 100% status.

XiaoMi Mi5 Battery

Xiaomi Mi5 battery 1-3

The XiaoMi Mi 5 features a Qualcomm Snapdragon 820 CPU and a 5.15-inch screen that supports a 1920 x 1080 full HD resolution. It runs MIUI 7 by Xiaomi, which offers wide options to tweak the battery alongside several power profiles.

The XiaoMi Mi 5 battery can’t be removed and has a 3000 mAh capacity like all the other smartphones on this list, and provides a complete day of usage like its rivals. We have had more time to play with the XiaoMi Mi battery and try different stuff, but we’ll be brief and we’ll only show you the most relevant results and relatable scenarios. Also, beware that everything was performed with the brightness set to auto and the GPS and Bluetooth disabled.

Half an hour of surfing the internet depleted 3-4% of the battery, only light web sites without heavy scripts or video were visited. 9 hours idle consumed 3% of the battery since the XiaoMi Mi5 can enter sleep mode and also cleans the memory when the screen is locked. Half an hour of online video consumed 4% of the battery. And the final test consisted of an entire hour of gaming, which consumed 18-20% of the battery.

The results mentioned before can give you an idea of how energy efficient the XiaoMi Mi5 can be. This smartphone besides the usual options that you can tweak to improve the battery stamina it also offers several power profiles for you to choose, from balanced to high or low performance, you can even create your own settings and schedule the times for these profiles to activate. You can also manage the power consumption of the installed apps and set restrictions or remove them since the OS will watch over the power consumption by default. All these feats are possible thanks to the MIUI 7 OS, which significantly improves the Android experience.

The XiaoMi Mi 5 battery can be quickly recharged thanks to the Quick-Charge 3.0 feature, in one of the tests the battery went from 40% to 100% of charge in only 55 minutes. Therefore, you can expect a total charge time of approximately 1 hour and 20 minutes if the battery has been completely depleted before plugging the charger.

OnePlus 3 Vs Samsung Galaxy S7 Vs Xiaomi Mi5 Battery comparison: The Conclusions

Well, now it’s time to make these devices fight and choosing a winner. Not literally of course, and we won’t be choosing a champion. Instead, we have decided to give you all the considerations you need to know regarding batteries. Firstly, the batteries of these 3 different smartphones are meant to last an entire day, but the Samsung Galaxy has the upper hand, because, in theory, it can last slightly more than a day. However, the stamina of the three batteries is pretty similar since they have the same capacity and the difference lies in the devices.

Battery comparison: conclusions 1

To give further insight on the lifespan of the three batteries a small test was performed on each device, the test consisted of playing a movie for an hour and a half in full HD with the Wi-Fi turn on and the brightness to the maximum. Afterward, the battery consumption was registered and here are the results: theOnePlus 3 lost 24% of its battery, while the Samsung Galaxy S7 battery only dropped 15%. However, the winner here is the XiaoMi Mi5 because the test only consumed 10% of its battery.

When it comes to benchmark software, Geekbench 3 was used to provide additional statistics, and the results were very similar as well. In the XiaoMi Mi5,the battery life scored 5353 points and time of 8 hours 55 minutes, while theSamsung Galaxy S7 received 5553 points and 9 hrs 15 mins. The OnePlus 3 achieved similar scores, but the results were unusually different each time that the test was performed.


It’s worth mentioning that the OnePlus 3 and the Samsung Galaxy S7 feature power saving modes, with this last featuring an extreme version of power save as well. However, the XiaoMi Mi 5 doesn’t stay behind by any means since it has multiple power profiles alongside the option of adjusting the power consumption of any single app installed.

Last but not least, we have the charging times for each device, which were obtained by using the Fast charge feature since not doing so would result in average times. The Oneplus 3 can be fully charged in only an hour, while theSamsung Galaxy S7 battery needs 1 hour and 15 minutes or 1 hour and 30 minutes on the Snapdragon 820 version. The XiaoMI Mi 5 requires approximately 1 hour and 20 minutes to complete its charge. However, the winner here is theOnePlus 3, because even a difference of 15 minutes it’s a great factor, especially nowadays with the busy lifestyle that our modern society has developed.

We hope that you have found this information useful, especially if someday you are thinking of buying one of these smartphones and the life of the battery represents a great deal to you.
