Galaxy Note 4 battery life tips

The battery is big enough for most, but you can always improve

The Galaxy Note 4's 3220 mAh battery is pretty large by today's standards, and gives the big phone solid battery life figures for most people. But counteracting that large battery are a powerful processor, bright QHD display and tons of software features, which can really chew into battery life depending on how you use the phone.

Most folks can make it through a day with battery to spare, but for those who find their Note 4's battery coming up short sometimes you may need to pull out a few tricks to get the most out of that limited battery capacity. Samsung includes a few intuitive features on the Note 4 to improve battery life, but it's all about how you use them. Read along with us and see how you can squeeze the most out of your Note 4's battery.

Review your display settings

Note 4 Display Settings

It's hard to deny that the Note 4 has a beautiful and bright display, but that AMOLED panel can single-handedly carve out a large portion of your battery life over the course of the day if you turn up the brightness. You may think that the screen only drains your battery if you keep it on to watch a few TV episodes, but every time you turn on the screen it's sipping up your battery.

To reduce the amount of strain the screen puts on your Note 4's battery life, head into the display settings and check out the options. You may want to turn down the brightness (which can be done from the notification shade as well) manually, but for most folks automatic brightness will do a pretty good job of managing visibility and battery drain. If you find the screen is often too bright for your eyes, turn off auto brightness — just know it'll disable the Note 4's high-brightness sunlight mode. The final big battery saver when it comes to the screen is reducing the screen timeout so that the screen turns off quicker when it's not being used.

Check for runaway apps and processes

Note 4 Battery Settings

The vast majority of Android apps interact properly with your phone and don't cause any issues, but all it takes is one or two bad apps on your phone to really kill the battery. Apps that incorrectly stay awake in the background or access the network can keep your phone from dropping to a low-power state, and you'll be able to notice when something's gone wrong.

If you're noticing faster than usual battery drain, go into the Settings and then tap on Battery to see the details for what's been draining the phone since its last charge. If you notice an app or two that you haven't used recently but is still claiming a large chunk, you may want to look into that app and see what's going on. Sometimes the fix is as easy as jumping into the app's settings, but in rare cases it'll be something the app developer needs to sort out.

Have your Adaptive Fast Charger handy when you do need a top-up

Galaxy Note 4 adaptive fast charger

Samsung ships the Note 4 with its own Adaptive Fast Charger, which juices up the phone at a much higher rate than your average charging brick. Though carrying a charger in your bag, purse or car may not be the most convenient thing ever, if you're going to bring one along make sure it's the one that came with the phone or a similar model so you're getting the quickest charge possible. It may even be worth using a slower charger at home for charging the phone overnight (when the speed isn't important) just to free up the fast charger for when you're out of the house or at work.

As a general rule you can also count on any other charger that's compatible with Qualcomm's Quick Charge — like the Motorola Turbo Charger and others (opens in new tab) — to power up the Note 4 at the fastest rate possible, as the phone supports that technology.

Consider a Qi charging back for casual charging

S-View Qi Charger back

Though the Note 4 doesn't come with Qi wireless charging out of the box, Samsung is now selling replacement back covers that add the feature if you so desire. You can get it in an S-View Flip Cover style or one that looks the same as the stock cover — just be aware that the latter is a tad thicker than the one installed on your phone out of the box and may interfere with any cases you use.

In either case, adding Qi charging to your Note 4 means you'll be far more likely to keep your phone topped up throughout the day by simply setting it on a wireless charger, rather than letting it get low before plugging in. Many of us that have Qi-compatible devices keep a charger on our desks and other areas where we spend lots of time, and it means our phones are rarely left with a low battery.

Get a replacement battery if you won't be near a charger

Galaxy Note 4 extra battery kit

While wireless charging is a bit more elegant, it doesn't really work when you're on the move — and for those who need a zero to 100 top-up instantly you can always go for a second battery. Samsung keeps winning folks over with the ability to remove the battery on its devices, and while it isn't a fix for battery life it does double your longevity if you're willing to carry around the extra battery.

Samsung has an official battery kit that comes with a charger to juice up the second battery, as well as a hard plastic case to keep it safe in storage while it waits to be used. It's cheaper than a Qi charging back and a charger, and there's really no comparable solution to popping in a full battery and getting back to work right away.

  • Try also installing Greenify. That app has done more for battery life than pretty much anything I've tried. Whilst not quite as good in non rooted mode it still improves things noticeably Posted via the Android Central App
  • whaaaat? according to those knight clowns the note 4 is perfect and has industry leading battery life! Posted via the Android Central App
  • It does. These tips are if you want more.
  • *cough* sarcasm *cough*
  • I use my Note 4 a ton and I get all day use out of it. I don't even use any power saver modes or apps. It's just a good battery.
  • I use mine very heavily and I always make it through the day. Posted via the Android Central App
  • Some crazy people expect their phone to last days on a single charge. Posted via the Android Central App
  • Find me a phone that does day S and I will buy it. There are none unless you use it sparingly. A full day, at this point, it a win Posted by my soon to be retired Note 3
  • THL 5000 Tesla (5000 mAh on 720p screen), THL 5000, Elephone P5000 and the incomming Lenovo Vibe P1 Pro. Onlye 5000 mAh+ beasts there. Also the Huawei Mate2 4G its suited for heavy battery use.
  • I have a note 4nd my battery dies insanely fast!!! it dies faster than any other device I have EVER owned

    Hope this is the case... The application memory areas may have to be optimized. This can take time and cause the device to temporarily use more battery while the optimization is in progress It can take time for the new software to optimize its performance and for the device’s battery life to normalize, which generally takes 2-3 days. Downloaded applications may not be optimized for the new OS version, as application developers do not immediately update their applications to support new versions of the OS. This may result in higher than normal battery drain, and in some cases device sluggishness, until the application is updated or removed. When in idle, battery usage is very low. When in use, doesn't matter what, projected battery life is only 3 to 4 hours. Got down to 11 % last night for first time ever after a day." I am now seeing better battery life when idling, but when used continuously, I use 20% battery life per hour.
  • I typically get 2 days of use out of my note 4, but I don't use the phone as heavily as others. Posted via Android Central App
  • 2 days wow I can barely make it through 12 to 14 hrs lol I play a lot of games on my phone and I like my display on full blast. It's such a great display that I don't like to turn it down. Posted via the Android Central App
  • Total brightness and lots of game play and you're getting 12-14? That's pretty good! Posted via the Android Central App
  • Aha yeah no kidding. My Note 3 gets no where near that. Posted via the Android Central App
  • You sound like one of those people who would make my eyes water if you handed me your phone to show me something.  I cannot understand people who like their screen brightness on max in a darkened room.  It is literally (yes, literally) painful to me. I use Lux so I can customize my auto-brightness.  At home, my screen typically ends up at around -5% (yes, negative) brightness :)  Of course, my apt tends to be fairly dark, most of the time.
  • I'm that guy. I never change the brightness of my phone. Posted on my Sexy Note 4
  • Yeah what's the point of having a phone with a big Bright quad hd screen if you don't use it to its potential. Brightness on full blast. Posted via the Android Central App
  • I never got the whole 'cripple the phone for battery life' movement. I understand turning off stuff you don't need or use, but the rest is beyond me. Posted by my soon to be retired Note 3
  • Whenever someone suggests crippling the phone to make it last, I immediately know that they have zero worthwhile suggestions. Anyone can shut their phone off and make the battery last.
  • For some people, not running the screen at full brightness has nothing to do with extending the life of the device. It's about not being a masochist.
  • Brightness full blast in a dark room is not the same thing as using your device to its full potential. I use my phone like crazy.  I just don't keep the screen on "melt my eye balls" level.
  • I agree fully, auto brightness is too bright on some devices, full brightness any where but outside is absurd. I don't need my phone providing ambient light. Posted via the Android Central App
  • same here ... using lux im generally around -20 ... just easier on the eyes ... if im watching something i just side up manually or hit a different profile ... full brightness is insane Posted via the Android Central App
  • I don't find the need to have my display up very high either, I keep it 20% (+/-) which is more than enough. For me, when it's higher than that, it's SO bright, it really does hurts my eyes. Besides, I'm a vampire & have the room fairly dark so you don't need the display very high to see well. Hey, to each is own....use it how you like to use it! Posted From MY Next Big Thing!!
  • I had a note 2. That had great battery life. Easily get though a day. I now have an xperia z2 and that is about the same battery life. Posted via Sony xperia z2
  • Have you been happy with the Z2? I just picked up a Z3C on Craigslist last night. Really liking it so far, and very much looking forward to the Lollipop update.
  • Just got one also. Love it. Best battery life I've ever had in a phone. Have never had a Sony device and I can say I am very pleased. Posted via the Android Central App on my Xperia Z3 Compact
  • Glad to hear it! I'm really liking it so far. The size is exactly what I want, and the build quality is fantastic. Also, I've had the thing unplugged since a little after noon, and with reasonable use, I'm at 80% right now (about 22:00). This bodes well. And the camera is just fantastic. I'm pretty sure people are going to be sick to death of getting pictures of my dog.
  • Screw them, everyone has to like dog pics Posted by my soon to be retired Note 3
  • Yeah, I love my z2. I prefer the ui to what Samsung has. The screen broke on mine randomly and had to have it repaired but apart from that it's been great. Posted via Sony xperia z2
  • Does the wireless charger work with a two piece case? I've always wanted wireless charging, but the case is more important to me. Posted via the Android Central App
  • Nope, the Qi back is at least 2x as thick as the stock back. You can't use it with most cases. (I'll have a review up in the next few days)
  • Thanks. Posted via the Android Central App
  • Aside from fit, would a case block the transfer of power? Posted via the Android Central App
  • You can get a Qi charger "insert", that fits under the regular cover. Just search for Galaxy Note 4 Qi receiver on amazon or ebay. They're a lot cheaper than the Samsung cover, too... A metal case would not work. Thick cases can maybe cause problems too. Qi isn't the most flexible wireless charging standard in the world...
  • Nope Qi can easily handle a phone with a case, so long as it isn't metal. Posted via the Android Central App
  • Ok, charging more frequently, wireless charging and carrying an extra battery are NOT ways to increase battery life. Please, stop with these articles or group them all in one. What is the deal with AC lately? You guys have the same article and just replace the device name (see Nexus 6 battery tips). There are the standard tips (with sarcasm):
    - Turn down brightness. Why enjoy that beautiful screen?
    - Turn off GPS, NFC, Bluetooth and everything else. Who needs them, right?
    - Don't install any apps. Hope flagship phones this year do a better job at increasing battery life, or make room for larger batteries.
  • I'll grant that keeping an extra battery and charging more frequently aren't really battery saving tips, but most of what you just said is stupid. Wireless charging is a very good solution for pretty much anyone who has a desk job. If you're sitting at a desk for eight or nine hours a day, it lets you make sure your battery doesn't drain for that part of the day without having to plug in and unplug your phone dozens of times a day. That annoyance adds up. Turning down your screen brightness from the default won't necessarily prevent you from enjoying your screen, and it's not something that would occur to the kind of casual user that this article is aimed at. Turning off services that you're not using at the moment is a very good way to extend battery life when necessary, and with a quickly accessible settings menu, it takes very little time. And I'm not sure exactly how dim you have to be to confuse "use the battery monitor setting to check for runaway apps if you're experiencing weird battery drain" with "don't install any apps," but hey, knock yourself out. And yeah, manufacturers should put higher capacity batteries in their flagships. You got the easy part right.
  • I leave GPS, Bluetooth, NFC and WiFi on 24/7 (full disclosure: I do have CarHome Ultra set to turn off WiFi while the phone is on the dock, because it's pointless) and I get great battery life on my Note 3. I've never seen them say "Don't install apps", but it is important for people to be aware that *some* apps *might* be written poorly and kill the battery.  Your "average" user doesn't really understand "what" the apps are doing behind the scenes, and might not even know where to look if they're seeing poor battery life to see if an app they have installed is responsible. As for "enjoying that beautiful screen", I can't enjoy my screen if my eyes are watering every time I look at it.  Some people like full-brightness 24/7.  Some people (like me) find it physically painful to look at a screen that bright in a dark room.  Outside, in the sun, obviously my screen is full-brightness because I use the auto-brightness feature.  It's why it's there.  Once again, your "average user" might not even know that the feature exists, so there's nothing wrong with pointing it out.
  • Really? Have a charger ready, get a wireless charging back, and get a spare battery are "battery life tips"? Really?
  • Always great tips, but I don't get the appeal of Qi charging. This thing is plugged in at your desk that you then sit your phone on to charge. It's plugged in. Why not just plug your phone in? It would save you a bunch of cash. I suppose it's slightly more convenient, but don't see why it's recommended so often, or at all.
  • I guess the only convenience is you don't have to mess with the wire and the port. I will buy a wireless charging base when they are big/fast enough to charge 3-4 devices at a time. For now, it makes no sense to me.
  • That and the micro USB port stays in pristine condition. Posted via the Android Central App
  • That's actually a legit point, even though someone down-voted you.  People don't seem to realize that every time you plug and unplug a micro-usb, you're causing wear to the port and the plug.  Granted, the micro-usb standard is designed so that most of that wear happens (hopefully) to the plug, but there's always a chance that something will happen. My daughter killed her phone because she accidentally knocked it off the desk while it was plugged in and it destroyed the USB port.  She had left the cord where it could be tripped over, even though I kept warning her about it.  She had to live with a spare battery and external charger and swapping batteries every morning until her contract was up (about 4 months).  She's a lot more careful with her phone, now :)
  • Seriously, this article is lame. How do items 3 to 5 help with battery life. Andrew you're better than this.
  • Was going to say the same... imagine an article about how to improve your gas mileage suggesting that you simply park at a gas station, carry extra fuel in the trunk or top up your tank at every corner... :/
  • Remove the Facebook app and use the Mobile site if you use Facebook at all. There's my tip. They only thing you really lose is the ability to upload pictures but there are plenty of apps that don't drain your battery that can manage that for you.
  • Amen to that. On top of that their separate chat app doesn't help either Posted via the Android Central App
  • Guys... you do realize you can turn off the automatic upload, right?  Also, the default Facebook sync setting is like 5 minutes.  Turn that *way* down (I have mine set for 2 hours, I think), and Facebook barely uses any power at all. And a separate Chat app has nothing to do with additional battery drain.  It's running the same code as it would be running if that code were still in the "main" Facebook app.  The reason for breaking it out is because Messenger has to stay running in memory (as a service) in order to receive push notifications about new messages.  If all the code was in a single app, that would mean that the entire Facebook app would have to stay loaded in memory.  Breaking Messenger out actually was a benefit to users, because it uses about 1/3 the RAM than the Facebook app did before they separated them.
  • +1 to that.
    Been doing that ever since they wanted access to battery stats. That way they can hide there inefficiency. Battery stats may not give all the answers for someone who blindly clicks update.
    Also if you have the mobile page up you can ad pictures then. You just can not start the process from your gallary. Posted via the Android Central App
  • Lol hide the stats. How about to pause the automatic uploads? Or to pause sync? Not everything is a conspiracy Posted by my soon to be retired Note 3
  • I have been doing this for years. The Facebook app is a real battery drainer. I am able to upload pictures using the mobile site.
  • You can turn off the automatic upload.
  • You can upload photos on the mobile site, but you just can't do it from the gallery. Actually, photos uploaded from the mobile site are in full resolution and/or are uncompressed. Whenever I upload photos from the app, it looks fuzzier.
  • What about recommendations for taking care of your battery, to extend the LIFE TIME of the battery, not just a single charge? Is it best to drain your battery fully the first few times you use it in a new phone? Is it best to not let it get down below 15%/10%/5%? Will frequent 'fast charging' sessions on the note 4 deminish the life time of the battery? Will frequent partial charges kill a battery sooner? Or are the battery scientists just that good these days that it doesn't matter how you treat your battery, you should expect full 100 range of your battery for 4 years?
