Improving your Samsung Galaxy’s battery life only takes a few tweaks here and there.
If your Samsung Galaxy isn't lasting as long as it used to, the good news is that it's the hardware itself.
Battery performance is influenced by a wide range of factors, from your device settings to apps running in the background, your screen habits and even the environment you're in. If you're outside and the weather is cold, you place your phone unlocked on your desk with the screen on at max brightness, or there are apps constantly refreshing in the background, your battery can quietly drain without you doing much.
Well, before you take your phone to the closest service shop to swap out that battery, there are a few practical, no-cost adjustments you can make right now to get more use out of every charge. None of these steps need technical expertise on your part and you won't need to spend money on new hardware to see a difference.
One of the simplest things you can do to protect your battery is to keep your device and apps up to date.
Samsung's Battery and Device Care menu lets you see exactly which apps are consuming power even when you're not using them.
Go to Settings > Battery > Background usage limits.
In the Battery menu, you'll see exactly how much each app impacted your battery life on any given day.
You can go from the Basic setting to Maximum.
Extending your Samsung Galaxy's battery life doesn't always need replacing anything or sacrificing how you use your phone day to day.
