Does your OnePlus 3 battery drain very fast? Does your OnePlus 3 overheat? Battery drainage and overheating are common problems on the OnePlus 3. Several factors contribute to the OnePlus 3’s poor battery life. This tutorial offers everything there is to know about quick battery depletion on the OnePlus 3.

Also, it offers tips for dealing with overheating on the OnePlus 3. Furthermore, the article provides the many steps you can take to learn how to improve your OnePlus 3’s battery life. So, what to do when your OnePlus 3 drains fast?

To answer this question, you have to evaluate your OnePlus 3’s battery performance. Assess and figure out the cause of the OnePlus 3’s bad battery life. Things that affect the OnePlus 3’s battery life include;

The number of apps installed on your device, poor battery settings optimization, and Google Play Services. All of these factors affect your OnePlus 3 battery performance. Read about Google Play Services battery drain on the OnePlus 3. Let’s begin with the battery drain and then we’ll discuss the overheating issues.

Best Battery Saver APP for OnePlus 3 – Greenify

To help save battery life on the OnePlus 3, install an app. The best battery saver app for the OnePlus 3 is Greenify. Greenify allows you to place all your apps in a state of hibernation, and they only activate when you choose to launch the app.

Greenify checks for the amount of time that an app remains inactive and places it into hibernation. With no apps running in the background, you see an increase in battery health on your OnePlus 3 device.

Greenify is one of the ways that you can resolve battery draining and overheating issues on your OnePlus 3. We dedicated an article on its usage and set up. You can read how to use the Greenify app to extend battery life on your OnePlus 3.

Also, check out how to resolve problems with a OnePlus 3 that won’t charge or turn on. Or, you can continue with the remaining tips in this tutorial.

3C Toolbox App

Another option is to use the 3C Toolbox App. This app, unlike Greenify, disables the background processes and applications. It also offers a more in-depth analysis of your system. Moreover, 3C Toolbox offers performance and optimization features outside of what Greenify provides.

Most people use the 3C Toolbox App to turn off Google Play Services. However, the 3c Toolbox APK requires root for most of the functionalities it provides. You can read the how to use 3C Toolbox Guide for further information.


Changing the brightness settings is a common fix. Turn off the automatic brightness feature. Set the brightness to a lower setting manually. Turning your OnePlus 3 display brightness down is an easy way to improve the OnePlus 3 battery life.

After you adjust the brightness settings on the OnePlus 3, limit location services. One of the most power consuming features of the OnePlus 3 is the GPS location services.

Moreover, Location Services incorporates more than just Google Maps. Social networking apps use the GPS functionality of your OnePlus 3 which in turn drains your battery even more.

Furthermore, while location services are useful, limiting those settings boosts battery life and this is what we strive to achieve. To define the location services usage on your OnePlus 3, do the following:


Go into Settings > Location > Mode. There are three options. High Accuracy uses GPS, Wi-Fi, & the mobile network to determine location. Of course, High Accuracy mode in turn uses a lot of battery life to do so.

Battery Saving, which, as the name suggests, reduces battery drain; and Device Only, which only uses the onboard GPS. You can also turn off location services altogether, but of course, that then limits your OnePlus 3’s capabilities.

You can adjust the settings to your liking. I use the battery saving option, unless I am out for a jog or walk, in which case I momentarily use the High Accuracy setting.


Another setting that you can tweak is the OnePlus 3 Sync settings. Sync delivers push notifications such as emails to your OnePlus 3. When you disable syncing, you also prevent a ton of app update notifications, which gives you time to connect your device to a charge port to install the updates. Of course, you can choose to disable certain sync features while leaving the important ones (email delivery) enabled.

Again, this is entirely up to you. Another step that you can take is to explore the battery settings on your OnePlus 3. This way you can get a feel of what is using up your OnePlus 3 battery life and take steps to reduce the load on the battery. Android devices have lots of settings that can reduce battery drain. Here are some of the things you need to do to evaluate your OnePlus 3’s battery life.


Go into Settings > Device > Battery and you see what’s making your OnePlus 3 battery drain very fast – and if you tap on each of the apps, you can then adjust the settings to improve battery performance.

Click on the dotted icon at the top right of the screen and you see the option for Battery Saver. If you enable this, you can specify when it should activate (never, 5% battery or 15% battery) and, when it does, it limits the over-usage of your battery.

This battery saving setting reduces app activity, disables syncing for some apps, reduces vibration, dims the screen and more. You can customize these features to your liking for optimal battery performance on your OnePlus 3.

However, none of them are mandatory, and you know what works best for you. To be honest, the Greenify app already saves a ton load of battery life on my device, and the extra settings that I adjust are for when I need to squeeze the extra life out of my battery. On the next pages, you learn how to calibrate OnePlus 3 battery.

Calibrate OnePlus 3 Battery

The Android operating system has a feature called Battery Stats. Battery Stats keeps track of battery capacity when it is full or empty. The problem is, however, that it is prone to corruption and displays data that isn’t real. Thus corruption causes the OnePlus 3 to turn off before reaching 0 percent.

Calibrating your OnePlus 3’s battery means getting the Android OS to correct this information. By knowing how to calibrate the OnePlus 3 battery, you restore the actual battery levels/stats.

It’s important to understand that you, technically, can’t calibrate the battery: it is, after all, just a cell that stores and discharges. However, lithium-ion batteries do include a printed circuit board (PCB) that serves as a protection switch to stop them from exploding or deep discharging.

How to calibrate OnePlus 3 battery without root access?

  1. Discharge your OnePlus 3 fully until it turns itself off.
  2. Turn it on again and let it turn off.
  3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
  4. Unplug your charger.
  5. Turn your phone on. The battery indicator will likely not say 100 percent, so plug it in (leave your phone on for this) and continue charging until it says 100 percent on-screen as well.
  6. Unplug your phone and restart it. If it does not say 100 percent, plug the charger back in until it says 100 percent on screen.
  7. Repeat this cycle until it says 100 percent (or as close as you think it is going to get).
  8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
  9. Fully charge the battery one more time without interruption and you should have reset the Android system’s battery percentage.
Note: OnePlus 3 Battery Drain

Please remember that performing this process all the time may harm your battery. Even when your battery is so dead, your OnePlus 3 does not even turn on; your battery still has enough reserve charge to avoid system damage. Perform this process once every three months at the most. If the OnePlus 3 requires calibration more often than that you have bigger problems at hand.

Put plainly: fully discharging a battery is not good for it. Trying to overload a battery is also bad for it. The good news is that charging batteries automatically shut off when reaching their safe limit, and there’s always a little in reserve even if your OnePlus 3 does not start.

However, again, do this only when necessary, because it does have an adverse impact on battery life. If you root the OnePlus 3, you can try the steps below (if not, move to the next tip):

How to calibrate ONEPLUS 3 battery with root access?

Even though it is not clear if purging the batterystats.bin file has any meaningful effect on how the Android system reports remaining battery charge, there are those who swear by this method.

So, in the interest of fairness, the process is below for your general knowledge (it is true that different manufacturers use the batterystats.bin file for various things). It is the same process as above but with the added step of a root-enabled app.

  1. Discharge your ONEPLUS 3 completely until it turns itself off.
  2. Turn it on and let it discharge and turn off again.
  3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
  4. Unplug your charger.
  5. Turn your phone on. The battery indicator will likely not say 100 percent, so plug it in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
  6. Unplug your phone and restart it. If it doesn’t say 100 percent, plug the charger back in until it says 100 percent on screen.
  7. You want to repeat this cycle until it says 100 percent (or as close as you think it’s going to get).
  8. Now, install the Battery Calibration app and, before launching it, make sure your battery is at 100 percent again, then restart.
  9. Immediately launch the app and recalibrate your battery.
  10. Once you’ve calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
  11. Fully charge the battery one more time without interruption and you should have reset the Android system’s battery percentage.

This one is a bit tricky. Sometimes it is best to check the battery of your device as a whole. Check for any form of bloating & malformations on the OnePlus 3.

Can gain access to the battery by removing the back cover? Yes? Perform a visual inspection of the battery. Do you see any malformations? No? Set the battery down on a flat surface. How about now? Does it remain flat? Does it rock back & forth?. Should the battery not sit flat then you need to replace your battery.



If your OnePlus 3 is still under the Manufacturer’s warranty which will also cover broken or malfunctioning parts, then you should take it in to have your device or battery replaced.

If there is no physical or water damage on your battery and it’s less than a year old, then you will likely get a replacement battery at no cost to you. Give your service provider a call and ask them about your cell phones warranty.

The OnePlus 3 is a powerful device! That’s one thing of which we can be certain. However, you probably think that you can use Facebook, Snapchat, WhatsApp, Twitter, and other social media apps all at once without slowing down your device while streaming media from Hulu, YouTube, Netflix, Fox Sports Go, Starz, or the ShowTime Anytime app continuously without problems. Heck, you’re probably browsing your favorite dating apps, using Google Chrome to do research on your next adventure, and so much more.  While all this is good, there is a limit to which you need to pay attention.

This restriction affects how long and how often you can do the same things over and over before they take a toll on your OnePlus 3’s performance. Let’s have a look at a couple of the things that your OnePlus 3 can do well but which might cause it to overheat in the long run.


Watching videos and other media content is one of the things that can make your OnePlus 3 a great device. Looking at a movie when traveling can make the time it takes to get to your final destination go by a lot faster. Watching movies and playing videos consistently, however, can indeed require more work from the OnePlus 3 processor.

And, not only can it consume a lot of battery power, it causes things to get warmer over time as well, given that our standards for media consumption move to using streams that offer a clearer picture with a higher definition.

Combine a load of playing a video with a load of a data connection when streaming content along with other processes running in the background (and over time your phone might start to get a little warm to the point of overheating.


The Android App store has a pretty wide selection of some pretty fun and entertaining games. With wore and more applications created and released every day. Some of these games and applications require more processing power than others.

It all depends on the complexity of the app. When you add this required processing power with extended usage, things can start to heat up. What you have to remember is that many of these games require you to use other resources on your OnePlus 3.

Many of the games require a data connection which means that your OnePlus 3 has to maintain an active internet connection via mobile data or Wi-Fi connectivity. The app might need to access contacts both on your device and social media accounts. All these things add up, and your device can get scorching over time.

If your device is a little older and no longer covered under warranty, then you might be able to find a great deal on a new replacement battery/device online from stores like Amazon or eBay. Here, you can find OnePlus 3 replacement batteries. Let’s continue!



Does your OnePlus 3 overheat when it’s in your pocket/bag/etc.? Take it out of the confining area to let it have a bit of fresh air. If you need to keep your device nearby, then you can keep it in a backpack (non-cluttered), locker, or in a protective case on your waist.


Protective cases are one of the best investments that you can make for a device. They help keep your device well protected and can certainly help save the phone from accidental falls or accidental damage.

Invest in a good case for your OnePlus 3. Use your phone out of the case for a while. Does the OnePlus 3 continue to overheat? Does it prevent the OnePlus 3 from getting hot?


Other less common but possible causes a OnePlus 3 can get hot.


Do you listen to music from your device while taking a shower? Do you keep your device in a hot pocket? Or has your device simply had an accident where you dropped it in some liquid? Power issues and overheating are common problems that water damaged OnePlus 3 can experience.

Locate the LDI (Liquid Damage Indicator) sticker(s) on your OnePlus 3. Make sure that your OnePlus 3 is not experiencing any side effects of moisture or liquid damage. Your OnePlus 3 may very well have moisture damage, and you might not even know it.


When was the last time your device got to rest for a few minutes? Do you leave your OnePlus 3 turned on throughout the day and plugged into a charger all night? Power it off. A little rest works wonders sometimes.

Apps and processes start to run and, continue to run until the user disables the process. Constant use causes minor software problems which you can often solve by restarting the OnePlus 3. Let’s look at some of the possible solutions.


This suggestion goes hand in hand with too many things running at once. Running an animated wallpaper and ten different widgets only serve to drain the OnePlus 3 battery life. After all, these things are going to be running all at once.

They cause your OnePlus 3 to work harder and cause your OnePlus 3 to heat up. Chances are your OnePlus 3 has some widgets on its home screen(s), and you didn’t even know it.


If you don’t know what overclocking means, then you can disregard this piece of advice. Manipulating/customizing the OnePlus 3 software for speed inadvertently causes overheating on your OnePlus 3.

Overclocking your OnePlus 3 can lead to a shorter lifespan for your device. An overheated OnePlus 3 can even suffer from hardware damage depending on how hot your Note is getting.


Outdated software is not likely the culprit for your OnePlus 3 heating up. However, updated software can help a cell phone run smoother. Updated software regularly provides fixes and might help to lower its average temperature.


If part of the device becomes corrupted, then locate, replace & repair the part. In this case for your device to stop overheating. Try to think back to when your OnePlus 3 started to get hot.

Did you do anything to the OnePlus 3 that could shed light on the recent overheating issues? Did you drop the OnePlus 3 accidentally? Are there any signs of physical damage on the OnePlus 3?

If so, try fixing the damaged OnePlus 3 part. The damaged piece potentially causes the OnePlus 3 to heat up. Locate, repair or replace the damaged OnePlus 3 part as soon as possible.


Can you remember downloading any new applications around the time that your OnePlus 3 started to get hot? If so, then you want to locate that application and disable it. You may also temporarily uninstall it. Rule out the possibility that it’s not that app that’s causing any problems on your device.

Does an individual application run when your OnePlus 3 starts to heat up? Do you have to force stop or force close that app to get your OnePlus 3 to cool down? If so, then you need to decide if it’s worth it to continue to use that app. You might want to rule out that application completely by temporarily uninstalling it.

If you uninstall it, and your device seems to stop getting hot, then you found the issue. You could try re-installing it to see if a fresh copy helps. If not, you need to keep that app (or apps) off your phone.

OnePlus 3 Overheating: Software

If you can’t get your OnePlus 3 to stop heating up, then consider a hard reset. A hard reset resets all user data on the device. A Factory Reset rules out the possibility that something found its way onto your device. A virus causes problems, and a reset would help remove “viruses” from the OnePlus 3.

A hard reset removes all information. What not to do when your OnePlus 3 is overheating? Don’t do the following if you OnePlus 3 heats up. You’ll be doing more damage than good:


Do NOT put your OnePlus 3 into the fridge or worse a freezer. Exposing your cell phone to extreme temperatures/moisture is dangerous. Not recommended!


Have you tried all of our tips? The chances are that your device has a hardware malfunction or another issue. Resolving this issue through standard troubleshooting is not possible. At this point, you need to look into your possible repair or replacement options. Check your OnePlus 3 warranty to see if your manufacturer covers your problem.

If so, then your cell phones manufacturer may be responsible for the repair or replacement of your unit. If you have confirmed that your OnePlus 3’s battery is at fault and is getting hot or overheating, then you may need to consider a replacement battery. You don’t want a hot battery to cause damage to your OnePlus 3 and cause even more trouble later on.
