How to fix LG G6 battery life problems

No matter how good battery life is on a phone, we always want more. The LG G6 manages to do pretty well with its 3300mAh battery, getting most of us through a full day on average — but of course, we don't use our phones the same every day.

Whether it's turning into a regular occurrence for your phone to hit 50% before lunch, or just a here-and-there situation of needing to be sure that you'll have enough battery for well into the night, there are a handful of things you can do to make the most of your LG G6's battery. And now that LG's leading device no longer offers a replaceable battery, these tips may be even more important to know.

Watch for battery-hungry apps

LG G6

One of the biggest (and easiest to pick up) issues that can destroy your battery life is a power-hungry app (or three) that start taking up more than their fair share of resources when they're not actively being used.

Open your Settings, head into Battery & power saving and tap Battery usage to see what's going on. For most users, individual apps won't crack the top five spots on the most-used chart. If you see one on there — perhaps a social media or streaming app — that's high on the list but hasn't actively been used that day, consider force stopping it with the "Stop" button or rebooting your phone; there's a chance it may have been a one-off issue.

Keep an eye on it for the next couple of days and make sure the problem doesn't resume. If it does, you can go through the app's settings to see if there are any you can tweak so it doesn't wake up so often — if it persists, you may want to uninstall the app.

Uninstall or disable unused bloatware

Pre-installed and unwanted bloatware is still a scourge on our daily lives, but you do have some control. Depending on where you bought your phone you'll have varying levels of pre-installed apps, but there's a good chance you could be looking at two dozen apps you just don't want. These apps may wake up and use battery throughout the day — while it's probably not a lot of battery, it's still wasted charge either way.

Go into your Settings, Apps and scroll through the list. If you don't want the app, tap on it and you'll see a large "Uninstall" or more likely "Disable" button at the top. Uninstalling does what you think it does; disabling simply turns off the app but keeps it on your phone to be enabled later if you wish.

One word of warning: if you're not sure what an app is, it could be an important part of a different app. If you disable an app and find that it's causing issues with another feature or service on your phone, get ready to go back in and enable that app again to fix it. You can quickly sort for disabled apps by tapping the "All apps" dropdown in the Apps menu and selecting "Disabled."

Turn off unused radios like Wi-Fi and Bluetooth

LG G6 quick settings

If you don't regularly use Wi-Fi or Bluetooth throughout the day, you can choose to turn them off and save a little battery life. Having the Wi-Fi and Bluetooth toggles in your notification quick settings makes it easy to turn them back on when you need them.

Keep in mind the location accuracy consequences of turning off radios.

Most of us do use Wi-Fi and Bluetooth throughout the day, though, and in those cases it's best to just keep the radios on for your own benefit. There's also the added benefit that your phone actually uses both Wi-Fi and Bluetooth to help locate your phone as a combined system along with mobile network triangulation and GPS.

This system uses battery, though — if you want to keep Wi-Fi and Bluetooth turned on for your own uses but not let the system use the radios for location, you can head into Settings, Location, tap the overflow menu in the top-right corner and tap Scanning. Uncheck Wi-Fi scanning and Bluetooth scanning. This will save some battery, but be aware that these settings are turned on by default for a reason, and having them off may impact your phone's ability to locate itself in the world when you're using apps that benefit from location information.

Configure battery saver mode

LG G6 battery saver mode

LG offers a relatively simple one-level battery saver mode, and it can be enabled either immediately using the notification quick settings or set up to turn on automatically at 15% or 5% battery. Most people will want the balance of having it auto-enable at 15% battery, since that gives you a chance to more gracefully finish off your battery over the course of a few hours, while keeping the phone at its full potential for the first 85%.

No matter when you enable battery saver, you get the same effects to extend the life of the phone: brightness is turned down, vibrations are reduced throughout the system, apps can be restricted when in the background so they don't drain your battery unless you're using them. When battery saver is on you'll get a permanent notification letting you know what's going on, and you can tap that notification to go into the battery saver settings.

Battery saver will automatically turn off when you plug your phone in or unplug it again after charging above the 5% or 15% threshold if you have auto-enable turned on.

Make a few changes to your Display settings

LG G6 display settings

Smartphone displays continue to get more efficient, but lighting up a big, bright panel is still one of the biggest drains on your LG G6's battery. Making a few changes to the way it behaves can save you a notable amount of juice throughout the day. Open Settings and find Display to start checking out your options. Here are the big three to look at:

  • Brightness: The lower you set your brightness, the less power the screen uses. But if you set it low and find you're just adjusting it manually all of the time anyway, you may want to just leave auto-brightness on and deal with the slight battery consequences.
  • Always-on display: The always-on display provides useful information, but drains more than its fair share of battery. You can turn it off entirely, or perhaps set a "daily timeout" so it starts turning on later in the morning and turns off early in the evening.
  • Screen timeout: Again in the self-explanatory realm, if your screen is on longer it's using more battery. By default the screen stays on for one minute after you've last touched it — consider dropping down to 30 seconds.

Update to the latest software

LG G6 software update settings

Now of course there's always the opportunity that new software can also bring some headaches, but in general you'll always want to keep your phone and apps up to date. On the LG G6, you can check for new firmware from Settings, About phone, Update center. You'll see an "App Updates" option to update LG's own apps, but the more important one is "Software Update" which can update your phone's operating system.

You should keep the apps you installed from Google Play up to date as well. Open the Play Store, swipe in from the left edge and tap My apps & games to check for updates. You can just tap "Update all" at the top if you see updates that are available.

Turn off automatic updates from Google Play

Google Play automatic updates

It may seem a little counterintuitive if you take our advice to keep apps up to date, but in terms of maximizing your battery life you won't want to keep Google Play automatic updates turned on. If you have "auto-update apps" turned on in the Google Play Store settings, the phone can check and download updates regardless of how concerned you are about your current battery life.

If battery life is the main priority, turn off automatic updates off entirely, and make sure to be diligent about manually checking on your own. While you're in the Play Store settings you can check the box next to "App updates available" under notifications, which will alert you when updates are available but let you decide when to update.

If you don't want to have to think about updates at all, but want a more battery-friendly setting, tap on Auto-update apps in the Play Store settings and select Auto-update apps over Wi-Fi only. This way the phone won't download apps over mobile data, which will save you on your data plan but also in overall battery usage.

Check out the 'battery optimization' settings

LG G6 battery optimizations

These settings aren't necessarily about raw battery savings as much as they are about finding a balance between app performance and battery life. Going back into the Battery & power saving settings, tap on Ignore optimizations (oddly named, to be honest) to manage which apps the system can aggressively slow down in the background to save battery.

Most people won't want to touch these settings.

By default, the system will be willing to optimize and slow down apps when they're not actively being used. This is great for battery life, and overall most people will prefer this. But on an app-by-app basis, you can choose to whitelist certain apps to perform however they want without the system scaling them back. Good examples of this are perhaps travel apps when you're on a vacation or perhaps a messaging app that you absolutely cannot miss a notification from.

Again, for the most part, you won't need to step into these settings unless you notice something odd happening with your apps not working properly. If you choose to ignore optimizations for some apps, be sure to check back in using the methods discussed earlier to make sure the apps aren't running rampant with your battery in the background.

Take advantage of Quick Charge when you do have to power up

Quick Charge charger

Yes, this isn't exactly fixing any battery life woes you may have — but sometimes your battery is going to die earlier than you want because you're simply using the phone more than usual. Battery drain isn't always going to be tied to something wrong or bad happening on your system, and if you have to charge up during the day you might as well keep it as brief as possible — in comes Quick Charge 3.0.

Quick Charge is an intelligent charging system that focuses on hitting your phone with a very fast initial charge — well over 1% per minute — and then tapering off after the first 30 minutes or so to preserve the battery's longevity. This means if you put your LG G6 on a Quick Charge 3.0 charger (Quick Charge 2.0 and 1.0 chargers will work too), like the one included in the box, you'll be able to add a significant amount to your battery in about 15 minutes.

If that's all the time you have, and you can get your phone plugged into either a wall, car or battery charger, make sure it supports the Quick Charge standard (opens in new tab) to make the most of the time.

  • Is battery life that bad?
  • My G6 battery has been amazing. Best I've ever had, and I'm not just saying that. Both my wife and I have been very impressed.
  • It's a generic article
  • Phone isn't even out yet WTF?
  • My ZteMaxPro beats this comical G6 which is drastically overpriced and 2016 specs. LG is small time and pretty worthless on the Android platform.
  • Oh I agree after having the G4, V10 both boot loop..... Then using the V20 for several months. LG makes toys.
  • They didn't say there are battery problems on the G6. The article is a blanket statement on how to extend battery life on almost any phone.
  • Stop misleading people G6 and HTC U junk has terrible battery life. Regardless of all the freebies, household furniture, cars, and TV's it won't help sell the G6.
  • The headline at the top of the page literally says "How to fix LG G6 battery life problems".
  • Exactly.
  • Welll, the title does say "How to fix LG G6 battery life problems" so it implies the article is geared to that device.
  • "Turn everything off. Use battery saver mode. Charge your phone." < Every battery help article ever. Super helpful.
  • I hate articles like this. There are no known issues with battery yet. Just pure click bait. This site must be doing bad and really needs the flow of ad cash.
  • Agreed. A lot has changed around here recently.
  • Micky mouse operation.
  • LG is the is the manufacturer doing poor on the Android platform. Hence poor sales G5 bootloop anyone. LG stands for LOW GRADE always.
  • My G5 hasn't bootlooped. G4, yes.. G5, no.
    My wife's G4 hasn't bootlooped either.
  • As much as I like the Modern Dad videos, we need Phil back ASAP!
  • Just keep the phone off. That should fix all issues.
  • 👍👍👍👍👍👍👍👍
  • Find some self-respect and stop running this generic advice headlined as clickbait for every hot new phone that comes out.
  • This is a TOTAL click bait article. There are no "battery life problems" (that we know of yet) and nothing needs to be "fixed". The first paragraph even says so. The LG G6 manages to do pretty well with its 3300mAh battery, getting most of us through a full day of typical use. This article, while it provides some decent information on getting decent battery life, applies to every single phone that exists right now. "Use less apps", "Turn on power saver", "Turn down the brightness and shorten the screen timeout". These have nothing to do specifically with the G6.
  • The G6 is the Government cheese handset people only want it because they can get freebies, household furniture, cars, and TV's. It's sad you have throw these types of freebies just to sell a worthless 2016 speced handset. LG smells like monkeys.
  • I don't see the G6 offered in the tent outside Walmart down on MLK Jr blvd.
    Nor in the Free Phone tent outside Salemi's Waffles and Fries.
  • These are the kind of headlines that make me leave Android Central for a few months.
  • Don't come back stay gone. The truth is the truth you can't change that.
  • I've pretty much stopped going to Android Central.. I decided to check it out today and see this article. I'm guessing these types of articles pay their bills as people will find them via Google Search "LG G6 Bad Battery" or whatever. However Android Police doesn't seem to do these type of articles and has some great APK breakdowns and other things.
  • what a fvcking joke of an article
  • LG is synonymous with crappy battery life.
  • I've never had issues and I've had all of the (Optimus) G series except the G PRO 2 and G5.
  • The article is not a joke at all. It's just that the title is very misleading. They should change those kind of titles to " How to extend your battery life on your xx phone"
  • If they did that it wouldn't get as much attention.
  • The phone isn't even in consumers hands yet and the reviewers all have pre production hardware and non final software. Jumping the gun a bit on these posts trying to get clicks?
  • Just a pointer - wifi and bt really don't impact battery life. If you leave BOTH on all day - you might get an extra 20 minutes at the end of the day. But you can get an extra 20 minutes by plugging your phone in for 1-2 minutes. Sometimes, leaving wifi on will save you more battery if you're using the wifi instead of a power hungry data connection.
  • Local Tmo had 2 on display. Looks nice but the display is awful dark, had to turn it up to torch mode just to get a bright crisp image. My Note 4 only requires half way on brightness to get the same results. I'm sure that will be a major drain on the battery.
  • Ah yes, the stream of disappointments have started for LG. Very predictable.
  • Battery life is not the only issue. The display is too dark, you have to really increase the brightness. When running GPS the phone gets extremely hot. There is also noticable lag. I picked up an LG G6 from Verizon, had it for few days then returned it. I was very disappointed.
  • Battery problems? The headline is very misleading. The G6 has stellar battery life for an Lcd screened phone. As for people above mentioning a dim screen....they must have been faulty handsets as the screen is super bright and I'm coming from a Galaxy s8 Plus before it
  • The fact that you had to qualify that statement is not very encouraging. The guy is a great surfer...for an Eskimo.
  • You guys really need to fix this title you constantly use. While the article itself gives very useful tips, which I used myself almost all the time, the title is very misleading. It should instead say "How to extend the battery life of your X Phone", that would make way more sense.
  • AC, shame on you! now recycling click bait articles!
  • Battery life is killer 2 days with 5 to 6 hrs sot...and screen is super bright ...i have zero issues even in bright sun light
  • There are no battery issues. This is a way for android central to fill their click bait quota. These articles are so generic and they do it for almost every phone just to get clicks. It's a shame really. Even with all these comments from fans of this site, on how much they hate these types of articles they continue making them 😠 it's very sad
  • I get 3 hours SOT but on average 2.5 hours. It's on the charger 2-3 times a day.
  • Just curious is the phrase "how to fix battery problems on xxx" being searched for more on Google or something? The phrase How to extend the battery life on xxx sounds much better and does not give a most of the time undeserved bad impression of a phone right off the bat to site visitors and turn away people actually shopping that dont even read the article and then see its just about advice for optimizing the phone in question. That's just how these articles strike me when I see them. A battery / phone problem is when the phone is hot as **** and the battery discharges in 2 hours. That's a problem. Extending is turning decent battery life into better battery life.
  • Very misleading article. These apply to ALL Android phones. You basically picked a phone model name out of a hat and filled in the blanks. Smh
  • Yes, these apply to all phones but the LG G6's battery is extraordinarily bad, even with the big battery capacity. They probably get more clicks when they apply a popular phone to the title.
  • I guess if you brand new to owning an android o/s phone this was a good article but I learned this stuff about 6 years ago..
  • Don't buy it
  • I just got this as a free upgrade if I trade in my busted LG G3 (because why not?). I also had an LG V10 because the 2nd screen got the best of my curiosity... turns out the battery was crap on that too. Looks like their mediocre battery life issues continue on the G6. What is it with LG that just continues to be always behind the Samsung curve. Huaweis are snappier and better phones... why can't LG replicate that? With the G6, I'm lucky to get 3 hours screen on time. I know there is a huge battery in there so what gives? I'll also say the G6 heats up in the back button just like the V10 and G3.
  • yes that's are good & great result
