Recently I got a Galaxy S3 smartphone, and I'm interested in prolonging its battery life. After charging it overnight and using it for a day, the battery usually starts running low in the evening. This doesn't seem bad to me since I use it a lot, primarily for web browsing, GPS navigation, and playing games (all CPU intensive tasks), which I do more of than talking or texting.
From the research I've done, it seems like there are at least three ways to prolong battery life:
From the research I've done, it seems like there are at least three ways to prolong battery life:
- Use power saving mode, which limits the maximum CPU performance, reduces the screen frame rate and lowers the brightness, and disables the vibrate function. I've turned this setting on.
- Get a battery that will last longer (7000mAh Li-ions are available on eBay that can replace the standard 2100mAh one). I probably won't do this, but I do want to get a car charger so that using the GPS won't drain the battery so much.
- Calibrate the battery. I'm not sure how to do this, or even if I should, because I've read different things about it. One article I read said you should fully drain the battery first, but another one said you shouldn't because that's bad for your phone. Yet another said that calibrating the battery is unnecessary because it happens naturally over time as you use your phone and recharge it.
