#How much battery life in my e7250 windows 10#
With Windows 10, there are additional power and display settings from the Settings button on the Windows 10 start screen. Use the High performance plan only when you need a boost for gaming or high-end graphics apps. Windows 10įirst off, if you are concerned about your Windows 10 laptop's battery life, head to Control Panel > Hardware and Sound > Power Options and make sure you choose a Balanced or Power Saver plan. Set as short a time as you're comfortable with for the Battery tab it's less important for the Power Adapter tab. On the Energy Saver page, you can set times for Computer Sleep and Display Sleep, both of which spring into action if your MacBook sits idle for a period of time. Keeping your display running while your laptop sits unattended is a needless waste of battery resources. Check the box for Slightly dim the display while on battery power. There is another display-related setting on the Energy Saver area of System Preferences. Not only will a display set at a lower brightness aid your battery life, but it will also be easier on your eyes unless you are sitting in direct sunlight and need brightness at its max in order to see text and images. Lower it to a point between super bright and depressingly dull. On the Display tab, you'll see a slider for Brightness. Open System Preferences and click Display.

Change your display settings Managing display brightness on Mac OS X On either a Windows 10 laptop or an Apple MacBook, you can usually do this on the keyboard, but there are a couple other settings to change that will help automate the process. The obvious move to extend battery life is then to lower your display's brightness. More specifically, it's the that energy goes into powering the backlight that illuminates the pixels on your laptop's display. The single biggest occupier of battery resources, day in and day out, is your laptop's display. If you answered "the display," you're right - for the most part. One battery has 400 mAh more, and this affects both how long it will last and the amp output.Īmp output assuming it is a 1C battery then:Ĥ400/1000 = Ah 4.4 (this is to convert mAh to Ah)Īnd C*Ah= Amp Output so the numbers remain unchanged and the bigger battery will output 400 mA (.4A) more currentĪs for how much longer the other will last:Ĥ.4 Ah at 4 amp draw the bigger battery would (theoretically, but voltage drop between the two batteries may make this false) last 6 minutes longer.Quick, what is the biggest drain on your laptop's battery? What's the difference between a 4400 mAh and a 4800 mAh laptop battery? It won’t hurt anything to go through the calibration cycle, and doing it will give you the confidence that the fuel gauge will accurately reflect the battery’s state of charge, at least for a couple of years depending on how you use your laptop. Is it necessary to "calibrate" modern lithium ion laptop batteries?īattery calibration doesn’t extend its life, rather its purpose is to calibrate its state of charge against the laptop’s “fuel gauge” so the laptop knows when to charge, stop charging, or shut down the laptop when battery charge is depleted - the reason calibration becomes necessary is because the battery’s discharge curve changes as it ages. Plug when it is in low level-Should plug when the battery level is under 15%. Unplug when it is fully charged-Do not plug when it is charged fully (do not charge over night). Keep it in a cool place-Do not let the battery in a high temperature (over 35 degrees Celsius). What is the best way to keep your laptop battery healthy?
