The Power Usage column tells youhow much power the process is using at this exact moment, while the PowerUsage Trend column shows you the longer-term trend. You can click the columnsto sort by either type power usage.For example, a process might currently not be using much power at this verymoment, but might be using a lot of power in general. Or, a process might beusing a lot of power right now, but it tends to use very little power. Focuson the trend for a better idea of how much power a process uses.Unfortunately, Windows doesn’t give you precise numbers here. It just givesyou a rough idea of power usage, which should be “Very Low” for most processeson your system. If a process is using more power than that—especially if it’srunning in the background—you may want to quit that process to save batterypower on your laptop or tablet.Microsoft hasn’t explained exactly what the various words here mean. We don’tknow the precise difference between “Very low” and “Low,” for example.

Screen is in most cases number one battery consumer. You can even see it fromyour device’s battery usage details:Some people are confident that Adaptive Brightness also should be disabled topreserve the battery charge. We believe that this function can workdifferently in different devices.So you can try turning it off and on to check out how this feature affects thebattery on your particular device.Nobody will be able to tell you exactly whether it is worth disabling or notuntil you find it out yourself.
Use Battery Saving Mode
This will decrease the CPU frequency, disable haptic feedback.Battery Saving Mode and Adaptive battery are not the same and shouldn’t bemixed.Battery Saving Mode slows down the the Android device in whole and decreasesperformance of all apps altogether while Adaptive Battery serves toredistribute power between apps based on their importance to the user.Thus, it is reasonable to activate Battery Saving mode when you believe thatyour device is likely to get discharged before you reach the power outlet.
Be Cautious With Battery Optimizing Apps
There exist a lot of apps on the market that promise to fix your problemsrelated to battery charge in one tap. But the things are not that upbeat infact.You should know that the overwhelming majority of those “optimizers”,“boosters” and various task killers won’t help you at all. Many of them arejust fake utilities belonging to adware and make things even worse.If talk about really effective battery saving utilities, you can try Purifyand Greenify apps. We provide direct links to them on the Play Store.
Bad battery life
Some people report solid battery life, particularly with the larger GalaxyS9+, but the smaller phone leaves something to be desired for heavy smartphoneusers. No matter your situation, here’s how to get the most out of the batteryyou have: * Use Power saving mode. Turning it on from the notification shade quick settings or the Device maintenance settings, the “mid” Power saving mode will reduce your screen resolution, lower brightness and stop apps from waking up in the background. You shouldn’t use this mode all the time, but if you’re low on charge it can be a life saver. * You can find battery-intensive apps by going to Device maintenance and tapping on Battery usage to see what’s taken up the most power over the course of the day. If something’s out of the ordinary, keep an eye on it and see if it continues to cause problems. * Uninstall unused apps, as they may be waking up in the background and using battery without your knowledge. If you haven’t used an app in a while, there’s no need to keep it around when it could be using up your battery. * It may look really cool, but you can save lots of battery by turning off Always On Display. Go to Settings, Lock screen and security and tap the toggle next to Always On Display. A compromise can be to limit the hours it runs (via these settings), rather than having it on the whole day.
Software isn’t up to date
One of the biggest frustrations for Android fans is how slow Samsung can be atkeeping its software up to date, even on its most expensive and populardevices. You can always check for available over-the-air (OTA) updates bygoing to Software update in your settings — but just because you don’t get anupdate this way doesn’t mean there isn’t one available. You can updatemanually using Samsung’s Smart Switch desktop software — just install it,connect your phone and tell it to download updates automatically. Sometimesthe staggered OTA rollout schedule can put you late in the lineup, and you canget it faster by going through your computer.If you’ve attempted to update over the air and via your computer, and stilldon’t have the latest software, chances are it just hasn’t been released foryour phone yet. Remember that Samsung doesn’t release the same software updateto all models of its phones at the same time, and there can be differences inrelease timing between countries and even individual carriers. On top of that,Samsung rarely keeps up with monthly security patches, and often rolls upmultiple patches into just one update every few months.”
