Since your surface runs windows, 10 and a desktop style, processor it’s able to truly multitask running many applications and processes all at the same time, when you’re plugged into power that’s an advantage. Programs are sitting there ready in the background and they open fast on command. But when you go mobile, the multitasking nature of the device can work against you and since your surface is a full windows pc, you can do amazingly complex things with it, but raw processing, power and battery life are not powers. So let’s take a look at the things that you should do to get the best battery life out of your surface and then we’ll discuss some technical details. We’Ll start with the battery settings page in the settings app go to system and battery here. You’Ll find your current battery level and the battery usage by app, so you’ll be able to see where most of your power is going. You can change the time period of the report to a week, which should give you a good overview, it’s, not the whole story, but it’s a good place to start at the top of the list. You’Re, probably going to see the apps that you use most of the time your web browser teams or zoom onenote outlook and as you scroll down, you might see some things that you don’t recognize consuming ever smaller amounts of battery. If you’re working in a very power hungry app like a video editor or a cad package, then it’s almost certainly at the top of this list, significantly challenging your battery life.

We’Ll talk more about how fast you could run your battery flat at the end of the video generally there’s, not much you can do about those apps consuming your power that’s, where you’re doing your work after all, but you may be able to optimize the app to Use less power or choose a less power, hungry alternative. For example, if you use google chrome as your browser, you might choose the new microsoft edge, because the word on the street is that it’s kinda on power, but it’s that long tale of smaller apps and processes. That could be letting you down so we’ll. Look at how to manage that also note on this page. The settings related to battery saver we’ll take a look at battery saver in a moment. Next we’ll look at apps that are starting up automatically when you turn on your pc. These apps will almost certainly be present in your battery report. Zipping small amounts of power. The trouble is that these apps add up and any app that is running is consuming power and reducing your battery life. Most apps that run automatically in the background on windows were not created with battery life in mind, so a lot of power can get wasted here on things that you don’t really need. There are two ways to see what apps start automatically on your computer. You can see the list in the task manager to open the task manager right click on your taskbar and tap on task manager.

You may need to click on more details to get the full task manager showing there’s a tab called startup. This page lists all of the apps that run every time. You turn on your computer or an easier way to see this information is in the settings app under apps and features then start up. My computer has 28 apps that want to run at startup. Imagine each one of these apps uses 0.5 of my battery i’d, be throwing away 14 of my runtime, so we’re going to go through this list and disable everything that’s, not absolutely essential. Some of these apps i want running on my computer at all times, but some not so much in my list, you’ll see things like the onedrive app that syncs my onedrive and sharepoint files. Personally, i want that one running microsoft edge is in there and since i use that as my browser i’ll leave it, on the other hand, some apps, like your phone and spotify, can go so i’ll, stop them from running automatically by toggling the switch to disable pdf Viewers like to have little apps running in the background the app effectively pre loads, the pdf viewer, so that when you click on a pdf it’ll appear quickly on screen. So you might see apps like adobe, acrobat or bluebeam review in this list. Personally, i use microsoft edge as my default pdf viewer since it’s usually already running it loads, a pdf very quickly, so i don’t need acrobat or bluebeam to be sitting there consuming my battery.

I can still use pdfs in those apps with this disabled. They might just be a tad slower to open when i need them i’m happy to pay that price for longer battery life you’ll also find apps that check for updates in here. I generally disable these, as the programs themselves usually check for updates when you run them anyway. The adobe creative cloud app fits that category for me, so i’ll disable. It guard your startup apps for best battery life on your surface, a 5 battery life saving here could give you 15 or 30 minutes of extra run time. Next we’ll take a look at the performance slider when you unplug your surface from power, and it starts drawing on the battery it’ll automatically change power mode to a recommended power. Saving setting. If you tap on the battery icon, you’ll see a slider with four positions, ranging from best battery life to best performance. This setting directly influences the processor’s speed and things like your screen brightness. For example. If you slide this slider along to the battery saver mode, you’ll notice that the screen dims slightly to save power, you’ll see a green indicator on the battery icon, telling you that you’re in battery saver, the processor’s, speed and power consumption is reduced to its minimum. Setting and some background apps are suspended in this mode. You’Ll also notice that my onedrive sync app is aware of battery saver mode, so it pauses filesync for me saving a lot of power.

You can override this or turn it off. If you want to but be aware that other cloud sync apps, like google, sync and dropbox don’t, currently do this, so they may not be the best choice. If you want long battery life, you can turn on battery saver mode from the action center directly to slide. In from the right expand the control panel at the bottom and tap on battery saver, so if you are planning to be away from power for a long day, you might even consider running battery saver mode from the outset back in the settings app under system and Battery you’ll notice, the settings that we mentioned earlier for battery saver when you’re running on battery and you get to 20 remaining by default battery saver will kick in, but you can change the level where it automatically kicks in here. On the other hand, if you slide that battery slider over to performance mode, everything will run to its maximum capability. If you are planning to edit a video or render a 3d model, then you’ll want to max this out for speed. Just don’t expect the battery to last. Usually i set this slider to something in the middle. I guess the question is: how much do these settings really impact battery life and what life should i be expecting from my surface battery it’s very hard to set a realistic benchmark? But let me give you some examples: the top spec surface pro 7 plus definitely has the shortest battery life.

In the surface pro range, it includes an 11th generation intel core i7 processor that can boost up to 4.7 gigahertz across its four cores. It has a thermal design power of 28 watts now that’s, just the processor that doesn’t include devices like the ssd, the display wireless radios and peripherals the high side of power. Consumption on that device could be up to 45 watts. The battery itself can deliver 50 watt hours of power. So, as you can imagine this surface, pro 7 plus could run flat in just one hour: it’d be red hot if it did, but fortunately it won’t, because it would only consume 45 watts for just a few minutes. In most circumstances, i’d expect to see between 5 to 10 watts of power consumed by any surface model across the range throughout a day, so it’s much more likely that we’ll see between 5 to 10 hours of battery life for most surface devices and that’s, usually enough To get you through a day of work on a battery, if you really want to watch the power consumption and see where your battery life is going, you might consider getting a battery monitor app. I use one that sits on the taskbar called battery bar pro. It allows me to see the immediate power consumption at a glance, and it tells me some interesting battery stats. There are many similar battery apps for windows. Battery bar is just the one that i use, but we’ll leave some links to other apps in the description below.

As well, none of them are especially great apps, but they can be helpful if you’re having battery issues. One of the key stats that battery bar pro tells me is the battery wear that’s a stat. That tells me a lot about how my battery is going. Lithium. Rechargeable batteries are the tech that makes all of our modern electronic devices possible, they’re, incredible, they’re, light, durable small and they charge and discharge fast. You can charge that 51 hour battery in your surface in two hours flat and you could run it flat just as fast that’s, a lot of current going in and out of a battery, but they’re, not perfect, and over time they will lose some of their capacity To hold power so that battery wear statistic shows us the difference between the battery’s design capacity and the current full capacity. So in two years that 50 watt hour battery on my surface, pro 7 plus might only be able to reach 45 watt hours. So i would have a 10 battery wear factor and that’ll get worse every year until it stops taking charge at all. You don’t need battery bar to get that stat by the way it just gets the data from windows and puts it into a user friendly format. If you run this command at the command line, power, cfg space forward slash battery report, you’ll get the raw data in a html file in your user folder it’s a pretty useful report, so run it.

If you’re having battery life issues – and the report that you can see here is from a surface pro 6 that’s about two and a half years old, it’s been used daily and in that time it’s lost about 18 of its capacity it’s, possibly been charged over 600 Times by now so 18, where is not out of line with expectations? If you’re interested in batteries pretty much all of the surface devices run a 2s lithium polymer battery that puts out around 7.5 volts. There are battery protection features built into the battery to stop them from over charging and dropping below the low voltage threshold, and the surface charger is designed to charge that battery blisteringly fast but carefully. Together, the charger and the battery management circuits manage and balance the cells in the battery, but what can we do to look after it long term? Well, the biggest factor in lithium battery life that you can manage is heat. It is a bit of a problem because processes put out a lot of heat that can’t be avoided, but there is heat that you can avoid, for example, never leave your device in a hot car and, if possible, it’s, not always practical, but let the device and The battery cool after use before you put it on charge again so charging your surface overnight when you’re not using it is actually a good idea. So those are some of the key things that i look at to give me the best possible battery life.

At my surface, i always miss something so if you’ve got a battery, life tip share it in the comments below we’d love to hear it.
