How to Fix Bad LG G4 Battery Life



The LG G4 smartphone has a large 5.5-inch Quad-HD display and a powerful processor inside that will drain the removable 3,000 mAh battery rather quick. Even though LG offered a free battery for many early buyers, users will still want to read on and learn a few tips to help get better LG G4 battery life.

Recently the LG G4 was updated to Google’s latest Android 6.0 Marshmallow software release, which should improve battery life across the board. Google made a lot of battery-saving adjustments, including a new “Doze” mode that puts apps to sleep. However, we still have other tips you’ll want to try.

The removable 3,000 mAh battery inside the LG G4 is bigger than most flagships, like the Galaxy S6, and has more than enough to get most users through an entire day. However, users are always looking to get more from their phone, and there are even some LG G4 battery cases worth considering.

If you’d like to get better battery life from the LG G4 and don’t want to be pulling off your back and swapping the battery, or buying a bulky case with a built-in additional battery, changing a few things and keeping an eye on certain apps will help things in the long run.

Android 5.1 Lollipop ran pretty good, but those who’ve received Android 6.0 are experiencing even better battery life. That said, some users are experiencing problems, or having odd battery drain. As a result, check out these tips.

Below are a few steps and simple tweaks that all LG G4 owners can do in a matter of minutes that could be just what you need to get a few more hours each day from the smartphone. Enough to make it through a night out with friends, or finish a long weekend at work. The G4 supports quick charge, and the charger in the box will charge it up to 60% faster than old traditional chargers. So always use the wall adapter that came in the box. With that said, lets get started.

Screen Brightness and Sleep Time

Having that big 5.5-inch Quad-HD screen playing video, displaying Facebook messages, tweets, or while browsing the web will be the biggest drain on the battery. Screen on time under the battery stats page in settings is important, as the display will usually be at the top of the list. As a result you’ll want to head into Settings > Display > Brightness and choose something that works for you. Auto isn’t ideal for conserving battery, and I use somewhere around 30-40% brightness. Setting it to auto means it changes on the fly, but the constant up and downs will slowly make battery life worse throughout the day.


At the same time, you’ll also want to set the display sleep time. This sets how long the display will stay on after you stop using the smartphone. Many users just drop a phone on any table after use, and if this is set to two or five minutes, your screen stays on for 2-5 minutes draining battery for no reason. I use 30 seconds personally, and always manually sleep my display after use, instead of just setting the device down. Meaning tap the power button on back to turn it off whenever you’re done using it. When you do this 100 times in any given day, that’s 100 times the screen will be on for 30 seconds (or longer) than it doesn’t need to be. You can also try the tip below to make your phone faster and get better battery life at the same time.

WiFi, 4G LTE & Bluetooth

If you aren’t using WiFi or Bluetooth, you might as well turn them off. Even though they’re minimal when it comes to battery drain this is one more quick and easy step. If you’re in a WiFi location (coffee shop) yet not using WiFi, certainly turn it off as the device will continuously search for a network. Bluetooth being enabled isn’t much of an issue, but while we’re here, disable it if you haven’t a need for it. Head into Settings and just slide both WiFi and Bluetooth to the off position. It’s the first two options.

Your best route is to head into settings > general > smart settings. Tweak these so WiFi is on when you’re home, and off when you leave. Bluetooth is on while driving to connect to hands-free stereos, but off when it isn’t needed. This all happens automatically,  which is why these are called “smart settings”.


Then of course, using things like Tethering will drain your battery, so use this only when necessary. Anything using 4G LTE and data often will drain the battery. Use WiFi as often as you can, but turn it off when not in use.

Control Location Services and GPS

When your device uses GPS for Google Maps and Navigation, or Facebook wants your location to share with the world, GPS will need to power on and will use a lot of battery. In Android 4.4 KitKat Google finally changed this system, and gave users more control over how all aspects of location services uses GPS, and thus, the battery. Settings > General > Location > Mode and select Battery Saving. This options is also available on Android 5.1 and Android 6.0 as well.

With Marshmallow “Doze” works on its own, which puts apps into a deep sleep when the device hasn’t been used for a certain amount of time. No settings or changes are needed for Doze to work, as it does everything automatically and can increase battery by 15-20%.  Even more on tablets.


If you want to really kill everything, turning location services completely off will be a big saver when it comes to battery. Just don’t expect Google Now to be as useful, give you directions, or find nearby restaurants and businesses. Facebook and Messenger apps won’t share location, and Instagram or photo uploads won’t have any location data. In general leaving Location services enabled and on Battery Saving is ideal. As this uses mobile networks, towers, and WiFi access points to determine location, instead of the power hungry GPS chip inside your smartphone.

Data, Gmail, and Google Sync

Controlling what is automatically backed up, synced with Google, and otherwise transferring data is another thing to consider. You’ll want to keep most of Google’s sync settings enabled for Calendar, Contacts, Gmail, and other things, but if you don’t need Gmail syncing and checking for emails every minute, change it. Gmail can be set to check whenever you’d like. From push, to 30 minutes, to never. Settings > General > Accounts > Google > and selecting account will show the sync options.


Having Google sync everything from Music, Chrome browsing history, and even saving app data and settings is nice, but also lowers battery. I’d keep this all enabled, or disable it but remind yourself to sync every now and again to keep everything up to date. Auto Backup of photos by DropBox, Google Drive, or Google Photos will also drain battery, so set them to be over WiFi only, or while charging. Most have that option.

Most of these backup and sync features are useful, but if you don’t use Google Photos, Google Play Music, Movies, and many other things in this area, disable them to save a little bit of battery wherever you can.

Install Battery Guru

The LG G4 and its software has plenty of battery saving features, but if you install the free SnapDragon Battery Guru software you’ll see better G4 battery life with changes you rarely notice.  This app learns usage habits and where you connect to WiFi and more to customize when settings turn on and off. Then does it automatically. Which results in nothing for you to do, but enjoy a longer lasting device.

This is an app that works on any Snapdragon powered device, and early tests show it works pretty good on the LG G4 and its 6-core processor. However, a lot of what this does is already handled by LG Smart Settings. See what works best, and only use one.

G4 Battery Saver

Another great option is using the built-in battery saver mode. This is a feature under Settings > General > Battery > Battery Saver. This feature is customizable and will let you set when your phone goes into this mode. I have it set at 15% for when it’s truly needed. It will turn down screen brightness, kill WiFi or data when not in use (so you may not get Facebook notifications, Twitter alerts, or Gmail notifications) and even turns off the notification LED from flashing and taking little bits of battery.


Go in and set this up as you see fit. Once your phone gets to 20% (or whatever point you choose) battery saver mode will kick in and start sipping juice to get you through those last few hours of the day. It isn’t ideal, but will work great in case of emergencies.

Other Quick Tips

Everything we just explained are small but worthy tweaks that actually make a noticeable difference on battery life, but you can always get apps like BetteryBatteryStats to see what apps are draining the most battery. Then stop using them. Things like rogue apps you may want to uninstall, or simply battery hogs.

If you’re on a flight or taking the train with no service, enable airplane mode to save it for when you arrive. Airplane mode turns off all data, radios, services and more and most phones can last 4-5 days on airplane mode. Occasional device restarts can also help to flush out the system and memory, and give your device a clean slate for the day or work week. It’s also a good idea to do a factory data reset (which erases everything) after the Android 6.0 update, for the best experience possible. And that includes battery life.

These are just a few of many different options available to users without getting deeper into the Android OS. Anything from custom ROMs and kernels can also severely impact battery life for better, or for worse. Enjoy the quick list, and if all else fails buy an extra battery since the LG G4 lets you swap it out when needed, or get an external portable battery.

    Snapdragon Batteryguru is not compatible with the G4…well at least the Sprint LGLS991 anyway

    I love your articles, but the “Smart Settings” has me baffled. This does not seem to exist on the Verizon version. I used the search function to look for it and still could not find it. Great idea, ‘tho.

      That is because Verizon removed it from the phone.

        this also was driving me crazy. I kept looking for this smart setting. I even went back to Verizon store and had the guy look. why did Verizon take this feature off. kind of annoying. when I first got this phone it would go down like maybe 2% in the evening and now it went down like 30% any idea why what happened

      The Sprint and Verizon versions of the G4 are jacked up to say the least. The best way to use the G4 is with the unlocked UK version on ATT or T-mobile. You also get a pair of high end LG beats earphones which are my personal favorite now. No carrier bloat and the best build in FM tuner I’ve ever listened to. Verizon wants you to use data to listen to music so they ripped it out. To top it off you can buy these unlocked devices for 400 dollars on Amazon now. Just got mine. Brilliant device.

    I cannot see how to change the settings so that Gmail will check for emails less frequently.

    I just read this article and my battery used 5%. I don’t know what happened, before when my phone was at 100% in the evening, it used just 2-3 % through the night, last night it increased to 13%..

    My battery on my G4 was GREAT until I did the Marshmallow update. Now the battery drains 1% every 2 minute of use and I have even seen the percentage go down while plugged in while in use… I have done all sorts of research and tried MANY suggestions to improve this, but it continues to be sub-par. I am dreading the day where I am away from my charger and I need the phone all day. It will not last. I am not satisfied at all with the T-Mobile LG G4.

    went to verizon because battery wouldn’t hold charge. They said the batteries are no good and that they would completely quit. They also said they don’t carry batteries I would have to order one on line. So now I have to spend a lot of money on a phone that I can’t use . Now I have to spend more money and find a battery.

    The LGG4 is a great phone with an immense amount of power battery life is pretty sweet but recently my LGG4 took all night to charge for some reason then just yesterday my phone wouldn’t charge while plugged in, there would be a clear indicator that it was charging but if I would check on it while it’s charging the percentage would still. Go down.. I tried installing a CPU cooler and a ram cooler(these apps just kill running apps in the back that shouldn’t really be on and are just wasting battery life as I’m typing my phone lost a percentage on its battery while charging.. This Extremely frustrating.

    Smart setting is useless since it need GPS permanently on. So you can have the wifi switched off according to your location but at the costs of having GPS on all the time.

    why is this article even specifically wrapped around the LG smartphone if all they recommend is generic power management adjustments? I find the article to be quite redundant.
