There isn't much to worry about, but better battery longevity is always a good thing.
Though the Galaxy Note 5 actually dropped battery capacity when coming from the Note 4, and also lost the ability to remove the battery for a fresh one, there isn't too much to worry about with the battery life on the newest Note. The 3000 mAh cell can easily get you through a day, even if you hit it hard, but no matter what phone you have there's always going to be a desire to get the most out of it.
Your options are relatively limited on the Note 5 for extending battery life while also keeping the experience enjoyable, but we're here to give you a handful of tips to make sure you get the most out of your battery.
1. Take advantage of Adaptive Fast Charging
One of the biggest advancements in phone technology of the past couple years has been faster charging. Using the same types of batteries and Micro USB ports, phone manufacturers have been able to boost charging speeds dramatically. Samsung has its own Adaptive Fast Charging brand on the Note 5 (and many of its other recent phones), and it'll give your phone a considerable battery boost in just 30 minutes on a supported charger.
Samsung ships a compatible charger in the box with the Note 5, which will get you up and running, but you can also use any charger branded for Qualcomm's Quick Charge standard as well. There are wall chargers, car chargers and even portable batteries with the tech, and if you have one within reach and your battery needs a boost, they're the best way to go. Once you get the experience you may never use a regular charger again.
2. Use Power Saving Modes when necessary
Samsung heavily advertised its Power Saving Modes in its previous generation of phones, and while the marketing has worn off a bit they're still included on the Note 5. This comes in two modes — Power Saving Mode, and Ultra Power Saving Mode. You're more likely to use the former. Here are the details.
Power Saving Mode is a way to save a small amount of battery (expect 5 to 15 percent savings over the course of a charge), but also only have a minimal impact on the experience of using your phone. When enabled, it'll reduce your screen brightness, turn off the capacitive key backlights, turn off vibration feedback and reduce the delay before the screen turns off when not in use. You can turn on Power Saving Mode manually — we like using the quick settings toggle — or have it enabled automatically at 5, 15, 20 or 50 percent battery.
Ultra Power Saving Mode goes all the way to turn off or change as many things as possible to extend your battery as much as it can. Your phone will go to a greyscale home screen, have only essential apps enabled, turn off data when the screen is off, and turn off additional connectivity like Bluetooth and Wifi. In this mode you can double your battery life, or more, but it really isn't a viable option for anything but extreme battery shortage situations.
3. Disable or uninstall apps you're not using
For as much as Samsung has cleaned up its software and pre-installed apps, there are still plenty of apps installed that you may not want. Even for those that you are generally indifferent to, they may be running in the background without your knowledge and taking up small portions of your battery over the course of the day. Each one may not use much, but if you have 15 or 20 apps periodically running that can really add up.
If you're using the stock Samsung launcher, head into the app drawer and tap the "edit" button — you'll see red minus signs over the apps that can be uninstalled or disabled. Tap each one you don't have a use for, and either disable or uninstall it. If you've moved on to a different launcher, you can use any of its built-in disable/uninstall methods, or just head into the phone's settings, tap on "Applications" and then "Application manager" to clean up unwanted apps.
Not only will this clean up the phone visually, it can also prevent runaway apps from taking down previous battery.
4. Consider a wireless charging pad
One of the things you get with a sealed phone like the Note 5 is built-in wireless charging, and Samsung does you one better and offers support for both leading wireless charging standards. You can set the Note 5 down on any Qi or Powermat charger, whether you have one at home or find one in a store or airport.
Once you get a taste of how convenient wireless charging is you may be hooked, and for the best chance of keeping your phone topped up throughout the day you may end up buying one for yourself. You don't need any specific charger, but keep in mind the size and shape of the Note 5 when buying — some chargers are better suited for some phones.
Wireless charging isn't as fast as a standard wall charger, but if you happen to spring for one of Samsung's Fast Charging wireless chargers you'll be able to charge up a bit faster than your standard off-the-shelf wireless accessory.
5. Think about screen brightness trade-offs
The Note 5's display is actually quite efficient for its size and has amazing screen brightness, but there's no getting around that one of the biggest drains on a phone's battery is the screen. If you're hurting for battery while away from a charger or just want to make your phone last as long as possible, drop your screen brightness down to where you can easily use the display but isn't any brighter. You can still leave automatic brightness turned on, as the way Samsung handles things here it'll adjust automatically but keep the overall brightness low as you've selected.
When you're in the display settings you can also consider turning down the screen timeout — or the amount of time it takes for the screen to turn off when not in use. By default the Note 5 leaves the screen on for a full minute before it times out, which is a bit much. Consider dropping it to 30 seconds or even 15 seconds if you really want to focus on battery life. If that seems short, consider the fact that you can balance it out by leaving "Smart stay" on, which won't turn off the screen when you're looking at it. But again, for maximum battery savings, you'll want to turn off Smart stay also.
