We expect it to give us constant updates from social networks, messaging applications, push mails and still last us a day. But that is not the case always. We find our phones dyeing on us mid‑day or even worse, only after a couple of hours of a full charge. Here I mention the top battery saving tips for Android smartphones.
Read on to know how could we fix it completely without losing functionality.
Before we start fixing, lets understand the fundamental causes first.
Three things that cause battery drain are the Screen(LCD/LED), the Processor(CPU) and the Modem (3G/Wifi), in the same order. Wasteful battery drain also happens from active sensors and radios like GPS, Bluetooth, NFC, etc.
Standby drains happen when applications that poll data (download data from their servers) cause the phone to wake up (even if the screen remains off) and use the CPU/Network. There could be almost 10-20 applications on your phone doing this, even while you were unaware.
With that said, here’s a list of things you can do to make your phone not die on you by the end of the day.
Android Battery Life Tips
(Go to Settings > Application Manager > Select Unwanted Applications > Uninstall)
For system applications, you can either disable them in the same Applications menu, else if your phone’s rooted, you can uninstall/freeze them with Titanium Backup or similar apps. Some known battery drainers are Maps, Google Now, Facebook, Google Talk. If you don’t need them, freeze them.
(Settings > Sounds > Disable Haptic feedback | Lockscreen Sounds | Touch sounds | Dial Pad tones)
Android’s basic functionality is to cache (keep in RAM in background) commonly used applications in the RAM, based on your frequency of use. While apps running in the background would cause battery drain, cached processes are not active processes and therefore don’t need to be shut down, contrary to what a task killer does. So every time the task killer is closing background apps, it’s countering the Operating system’s primary functionality of caching, which would hit in soon after again. It’s the vicious circle of killing and caching the application that shall drain the battery more than you expect. So if you have any such BATTERY SAVING apps, push them into the dustbin. Android doesn’t need them for sure.

Control Battery Drain (if Rooted)
There are a couple more things you can do if you have a rooted phone.
Apps to monitor battery drain
You can monitor the battery drainers with applications like BetterBatteryStats, GSam Battery Monitor and Wakelock Detector. I personally would suggest GSam battery Monitor for the not so tech savvy person. It’s a graphical UI and hence easier to monitor rogue stuff. For the advanced level person I’d suggest BetterBatteryStats as it really goes deep into numbers and application and kernel level details. Wakelock Detector lies somewhere in between.
