The new OnePlus 6T is an impressive phone with plenty to offer, but it isn’t perfect. In fact, now that more than a few people own one we’re starting to see complaints about bad OnePlus 6T battery life. Even with the bigger 3,700 mAh battery this year. If your phone isn’t lasting as long as expected, below we’ve detailed more than 10 tips to fix your problems.
You won’t need to read over the manual or browse the OnePlus forum for hours to find answers. We have solutions to the most common complaints. Keep in mind that everyone uses a phone differently, and not everyone will experience the same problems.
While this phone will get better than average battery life, even with the huge 6.41-inch screen, some will eventually run into issues. That’s just how it goes with smartphones these days. Either way, things can always be better.
Basically, you’ll want to know about these steps we recommend, settings to change, or options that will improve your experience and battery life.
How to Fix Bad OnePlus 6T Battery Life
Running nearly stock Android 9 Pie and packing a big battery, these phones last pretty long already. If not, you have several options or settings to work with. Changes that can make a noticeable difference in overall battery life. In this post, we’ll show you those changes or help you figure out what’s causing poor battery life to begin with.
Before we begin, make sure you’re running the latest OxygenOS update from OnePlus. At the time of writing, that’s OxygenOS 9 which added lots of new features, battery optimization and brought it up to date with Android Pie. Go to Settings > About Phone > Check for updates
Find Apps Eating Up Your Battery
The first step to solving any battery situation is finding out if an app is causing problems. Something gone rogue that’s draining the juice too fast.
It doesn’t matter if these apps come pre-installed or it’s something you downloaded from the Google Play Store. Sometimes apps just don’t work right. Your phone will send you a notification if an app is using an abnormal amount of battery, so watch out for those alerts.
If you use an application a lot, it’s going to drain your battery. At the same time, some situations occur where an app uses more than it should, and that’s what we want to avoid. Head to Settings > Battery > and tap the battery icon. This shows you a full breakdown of apps and their battery usage.
We’re looking for things like Android System, Display, or Android OS to top this list. If other random apps are near the top, something isn’t right. Click the app and select “Force Stop” or uninstall the app to prevent further issues. Take advantage of this menu in settings to help find misbehaving apps.
Reboot Your OnePlus 6T
While this is a great tip overall, it also applies to our first category. If your phone (or an app) is acting up or draining the battery, reboot your phone. This is often the easiest and fastest way to stop a pesky problem or fix a small issue.
Whether you want to give your phone a fresh start for the day or you noticed the battery draining too fast, give it a quick reboot. Long-press the power button and select reboot, or manually reboot your OnePlus 6T.
Face & Screen Unlock
With the OnePlus 5T and the newer OP6, Face Unlock was draining the battery on some devices. And now, the new OnePlus 6T has the same Face Unlock, and a “Screen Unlock” mode where the screen glows at 100% brightness to scan your fingerprint. It’s a feature you’ll love, but it could also be shaving minutes or more off your daily use.
Basically, keep an eye out for Face Unlock and Screen Unlock in the battery usage menu we mentioned earlier. If they’re using too much juice, try a different unlock method.
Disable the Ambient “Lift” Display Feature
OnePlus’ latest phone doesn’t have an always-on display like a lot of the competition, but there’s a similar feature known as Lift. When you “lift” up the phone the screen will turn on to show you notifications and such. It’s helpful, but it can also go off when it shouldn’t, or when inside a pocket.
Then, in the near future, we believe an update will add the “Always-On Display” and you’ll want to disable that too. Well, if you need better battery life, of course.
Screen Brightness & Sleep Time
Every little bit helps, and two big ones are screen brightness and the sleep timer. With a huge 6.41-inch AMOLED screen, you’ll want to pay a lot of attention to both of these. The average person checks their phone over 140 times a day, usually just to see the time or check a notification. This adds up throughout a day and can really lower battery life.
Make sure you hit the power/sleep button when you’re done using the phone, so the screen isn’t just turned on for no reason. Most people just set the phone down when they’re done, and the screen stays on wasting precious juice. Often for 1-2 minutes EVERY single time. That’s 140+ minutes a day of wasted battery. You can adjust the “sleep timer” so it shuts off faster. We also recommend keeping the screen brightness at an average level.
Head to Settings > Display > Sleep > and set this to 30 seconds or one minute, not 5 minutes. That way when the phone isn’t in use, it dims and will go to sleep after that amount of time.
Use a Black Wallpaper
Did you know that using a black wallpaper will improve battery life? It’s not a ton, but every little bit counts. The OnePlus 6T has an AMOLED screen and they’re very efficient at displaying dark colors. Plus, it doesn’t need to “turn on” pixels to show the color black.
After you’ve downloaded a nice wallpaper long-press a blank area of the screen and go into Wallpapers to apply it.
Turn Off OnePlus 6T Features You Don’t Need
This next one is a biggie. While the screen is likely the biggest drain on the battery every day, a lot of the extra features can have an effect too. While some of them are great, others keep the phone awake for no reason and can hurt battery life. As you saw from our battery usage image above, the Face Unlock feature was using more battery than we expected, as it keeps sensors on 24/7 watching for a face.
So, turn off features you don’t need or don’t plan on using. Then, other things like gesture controls, Google Assistant “voice detection” and features in the Settings > advanced category can drain your battery too. Go to Advanced and turn off anything you don’t plan on using. OVer an 8-10 hour day, every little bit adds up.
It won’t give you better battery life, but go to the calculator app and type in “1+=”.
WiFi, 4G LTE, Bluetooth & GPS
Again, small changes don’t seem important, but when you add these all up over 8 hours, they can give you an extra 1-2 hours a day of battery. WiFi, BT, and GPS all will drain your battery to some degree. Mainly, turn them off when they’re not in use. WiFi is easier on the battery than 4G cellular connections, but when you aren’t on your home WiFi the phone will constantly search for a WiFi signal. This hurts battery life.
For me, the most noticeable change is cutting out what apps access and use GPS. Whether that’s Google Maps or Facebook Messenger trying to find your location. Disabling GPS on multiple apps can give you way more juice than you’d think.
Head to settings and tap the magnifying glass. Type “Location” then enter location settings and tap the battery saver mode. GPS isn’t as accurate, but you’ll notice an increase in battery life. Your OnePlus 6T will use WiFi and 4G LTE for details on your location.
OnePlus 6T Battery Saver & Gaming Modes
Don’t forget to take advantage of battery saver or Gaming Do-Not-Disturb modes. Like we see with every phone, OnePlus has a pretty capable battery saver option on top of the already great Android 9 Pie controls. This means it will reduce performance, vibrations, screen brightness, background data, and a few other things only when necessary.
Set the phone to turn on battery saver mode around 15% remaining, or even 10%, and only get the bare minimum controls in order to keep the phone running as long as possible. You can customize when it turns on, and you can even add/remove features from the excluded list during battery saver moments.
Then, OnePlus added a “Gaming DND mode” that basically stops any and all notifications while you’re gaming. Even if you’re not gaming, this will keep the screen off when you need to save as much battery as possible by limiting all notifications or messages. This works great and can be used along with the alert slider.
We also recommend trying the Snapdragon BatteryGuru. This app learns your habits as you use the device, and starts turning things like WiFi, GPS, Bluetooth and other modes on or off for you. Basically, automating a bunch of small tweaks that will add up over time. This lets you focus on things other than tinkering with settings and controls.
OnePlus Android Pie Battery Tips
Those dealing with poor battery life will want to look at this generic Android Pie problems guide. Being early software things are subject to change, but we mention some of the biggest complaints and offer resources to fix them. OnePlus will likely release a few fast software updates for the 6 and 6T, now that they’re both on Android Pie.
A Few More OnePlus 6T Battery Tips & Tricks
At the end of the day, battery life always comes down to how you use your phone. Everyone uses their phone differently. Some are hard on phones and have 4-5 hours screen-on time, while others use them sparingly. There is a huge thread at the OnePlus 6 forums all about battery life, and how to prolong usage. Those same tips and tricks all apply to the OnePlus 6T, as they’re the same phone on the inside.
Additionally, download the app BetteryBatteryStats. This program shows you what apps use what, what you use the most, and will highlight any potential problems or bad habits. It’s a pretty powerful app that will give you more insight into how you use your phone.
In closing, stay tuned for the next few software updates from OnePlus. They’ll probably fine-tune the software, patch a few bugs, and further refine the software, battery life and stability. They’re one of the best manufacturers when it comes to fast, helpful, and timely software updates.
