Maximizing Android Phone’s Battery Life
Today Android is the largest selling smart phone OS with millions of users out there. If you are also one of those who have just turned up for Android or an old user you would be facing problems on constant battery run out. All the fancier phones seem to never hold enough battery to last more than a couple of days at a time. Some phones might even die midday despite just sitting there on your desk the whole time. To maximize battery life is no rocket science and requires general principle is to get rid of the things that are draining the battery the most.
Using Android phone require charging least once a day and almost every day. After constant using through out the day then charging is needed twice a day. Charging cable or charger is required at desired time. Unless phone has an amazing battery with better 2500 mAh or about. Apart from that if you have mobile phone with 8 hours or 10 hours battery life specifications then after few months of usage of your phone the battery life would be reduced considerably due to physical aging of the components and life of chargeable batteries is not long enough.
One must try and keep the phone somewhere that isn’t too hot whenever possible or user would end up needing to replace the battery a lot quicker.
Built-in Battery Usage Screen
There’s a screen built into Android and it can tell you exactly what is killing your battery. Head into Settings –> About Phone –> Battery use to see what has been killing your battery life.
From this screen, you can usually see what apps are the worst offenders, and you will probably notice that the biggest problem at least, the biggest one that we can fix—is actually the backlight on the phone.
Adjust the Backlight to be Less Bright
The backlight is usually the biggest problem, you should probably adjust the settings. Go to Settings > Display > Brightness, where you can choose to automatically adjust, which usually works fairly well, or you can just turn the brightness down. If your phone doesn’t have this option, start at 50% and see if that suits you, the lower you take it the better it will be for your battery life.
One should set screen timeout on your mobile phone. It’s the time amount in inactivity before your screen goes to dark (power saving) or auto lock. Keeping your mobile phone setting for longer timeout it’s just wasting the battery and on the other hand if you set it for 20 or 30 seconds, it would be not that much difficult for you to unlock your devices and be back to your work.
For the LED screen on some of the Android devices, you will not find the option of auto brightness. It will have the settings from low, medium and high. The high setting will keep you screen for the maximum power usage, the medium is nice for indoor use and the low one works very well in the dark.
An interesting fact is that on your LED screen, dark wallpapers consume less battery than their counterparts.
Disable the GPS Location Features
The GPS uses battery as if no other application is around to use battery. The battery dies far too fast. But the user do not know is that a lot of other applications use the GPS as well. User can change the GPS to use wireless networks, and uncheck the option for Use GPS satellites—this will make the GPS a little less accurate, but it will save your battery.
The power control widget is useful for switching the GPS on and off, and you should keep an eye on your notification bar: an icon will appear whenever the GPS is activated.
Disable Your Wi-Fi, Bluetooth When Not Required
Wi-Fi can really speed up accessing data on your phone, but it can also be a big drain. To enable Airplane mode, go into Settings > Wireless & networks > Airplane mode.
If you’re close to a reliable Wi-Fi network during the better part of the day, having Wi-Fi always turned on may be favorable from a battery point of view, since the Wi-Fi radio uses less battery than the 3G radio. Also, when Wi-Fi is on, 3G is off. You can make sure Wi-Fi always stays on by going to Settings > Wireless networks > Wi-Fi Settings. Press the Menu button, tap on Advanced, Wi-Fi sleep policy and select the Never option.
In other cases disable Wi-Fi from the home screen widget or from Settings > Wireless networks > Wi-Fi.
One can toggle the Wi-Fi on or off with a widget or shortcut—there’s a built-in widget included in Android phones, or you can use the AnyCut or BetterCut utilities.
If you aren’t using a wireless headset, turn off Bluetooth to save the battery life. To never turn it on go to Settings –> Wireless & networks–> Bluetooth.
Disable Animated Wallpaper/Background
Live wallpapers are a pretty cool feature, but that extra animation constantly running on the home screen will use up more battery than standard wallpaper will. The live wallpapers apart from consuming the battery continuously it also consume a part of your processor as the process runs continuously.Get rid of it for a small extra battery savings. If the phone has one of the AMOLED screens; dark wallpaper will use less juice than a bright one.
Disable Constantly Sync Apps
The built in email application (not the Gmail one, which uses Push technology) can eat up your battery badly because it syncs with your email too regularly. If you have sync settings available then you can set sync after every hour or so at less frequently because you might be receiving mails not all the time and continuously.
Open up the Email application, go and choose Account settings –> Email check frequency from the menu. User can always hit refresh manually when you want to read your email.
The same thing holds true for other accounts, like Twitter clients, which are even less important to update all the time. Settings –> Background Updates from the main screen.
The Facebook application polls automatically in the background, and you can customize the refresh interval for that as well. From the main Facebook screen—the one with the icons—head into Settings –> Refresh interval from the menu.
Must not use task killer
Many out of date article suggest task killer to prevent juice on your droid. One must not use these because they certainly kill applications but what is required is to remove CPU hungry aaps. instead of those which are sitting on your RAM. These apps restart themselves again and consume even more power instead of remain sitting in RAM ready to be used.
One must use something that show CPU-usage instead of RAM, like WATCHDOG task manger (Lite) which alerts you when an app goes above a certain amount of CPU cycles so you can kill it if required.
Uninstall Unrequired apps.
Some apps act as complete malware-like and keep on running. Go to setting> Applications> Manage Application. Hit Uninstall and get rid of them.For particularly clingy apps, go to Settings> Location and Security> Select Device administrator, and uncheck the app there to e able to uninstall them.
Wireless Radio & 3G
On connecting to 3G internet on mobile phone, the battery meters quickly drain out. Again, it’s not the problem of your phone or the battery, the 3G and the 4G networks consumes more battery as the connectivity is faster.
So until and unless one is not using the 3G services, its better to switch to GSM mode network rather than going with the dual mode network or the WCDMA mode which drains the batter faster than GSM mode. The reason is when you are on dual mode, the phone would sending/receiving signals from both 2G and 3G, hence require power for both to operate. This alone has a big impact on your battery longevity.
get Paid Apps
Advertisements in free apps tends to take a heavy toll on battery life.
