The Samsung Galaxy S2 is currently the smartphone on top of the throne. It packs a hefty battery that will handle all your needs, but doesn’t mean you can optimize and maximize it’s battery life. Here’s how to do just that with your Galaxy S2′s 1650 mAh battery.
Control your screen brightness
The most battery intensive aspect of the Galaxy S2 would be the awesome Super AMOLED Plus display, although it has been optimized to reduce drain, it still the main source of drain. What you want to do is deactivate the auto-brightness feature in the Settings menu and push the brightness slider right down.
If you want to retain the auto-brightness feature, at least make sure you download the latest Galaxy S2 software update through Kies â€“ it includes a fix thatâ€™ll stabilze the auto-adjust effect thus preserving a bit more power
Avoid live background and go simple
As appealing those live wallpapers are, they are not battery friendly and drains a lot of it. It is really unneccessary if you cherish your battery life to last all day.
Stick with a simple static background which will be much less demanding on the battery and still look good, so switch to a darker wallpaper if you really want to save power to avoid rendering vibrant colors.
Kill background/inactive apps with Task Manager
The beauty of an android is its ability to multitask and run numerous apps at the same time. The downside to this is super fast battery drainage and even slowing down the device due to RAM throttling if you get to that point.
So use that handle app that Samsung has included, Task Manager, to kill all those unnecessary apps that are hogging all your RAM and draining your battery life.
The phone can even be configured to take care of some of this automatically through its Power Saving Mode, which can be configured to kick in when your battery drops to a certain percentage.
Limit network access
How your Galaxy S2 connects to networks via Wi-Fi or 3G plays a huge factor in your battery life. The are couple of ways to optimize power here, one being turning off Wi-Fi when not in use.
You could also consider lowering the frequency with which your Galaxy S2 auto-syncs to draw in your email. Furthermore, you could even turn off auto-sync altogether and simply sync manually whenever you need to if you are not expecting anything of importance.
Lastly, if you only need to use your phone for regular voice calls and text messages, consider opting to use â€˜GSM onlyâ€™ in the Network mode menu â€“ this forces your phone to use 2G only rather than switching between 2G and 3G depending on availability.
Learn to charge properly
You might not think there is a proper way to charge your battery to get the most out of it, which is true. There are techniques rather than a proper way, which is really utilize the battery full capacity.
There is no need to always top off the battery to a full charge whenever you get a chance, rather use the battery to its fullest as in draining it from your usage then charging it back up several times. This is more of a maintenance thing for your battery to establish itself sort of and it’ll do better for your Galaxy S2 in the long run.
