1. The screen spends outrageous
Most current mobile notable for its large touch screens, which are around 4 inches in size, and using technologies such as AMOLED or Retina Display, which provide them with a high quality image, but the battery to drink.
To minimize damage, try to disable the automatic brightness, as this functionality takes mobile to continuously detect the degree of external light to determine the brightness of the screen, with a high battery drain. Manually put the lowest screen brightness, long enough to see the screen well. And if you want to increase the brightness when you have to read a long text or when you're in places with little outside light.
Android, even you have a very interesting application, Screen Filter, applying a filter to your screen that will save a lot of battery to your mobile phone.
2. Check your connections
Bluetooth, GPS or WiFi connection are spending a lot of battery, so it is imperative we have them turned off when not in use.
In this regard, note well in applications requiring usually use these connections, and remove access to them if necessary. For example, Google Maps or Foursquare can operate and locate your position without GPS, as the cell triangulation method (from the antennas of cellular coverage), although less precise, is sufficient for its purpose.
Yes, provided you have one available at your fingertips, using WiFi, spends less than 3G. Especially for important data downloads (do not you spend to upgrade your applications in the metro!).
3. Are you covered?
One of the main reasons for the battery drain is seeking mobile coverage makes the antenna of your phone. In situations of little or no coverage (downstairs of a bar, incommunicado friends house ...), you have two options: turn off your phone or use Airplane mode. This mode will not be activated mobile phone option (no calls or messages), but save battery when not look "like a madman" the coverage you need.
The same applies to 3G. If where you do not have such coverage, why maintain the data connection? Disconnect the data. Your phone thank you.
4. Pull and Push
Our phones notified us every time we receive an email, a mention in a message on Twitter or Facebook. But do you really need to know, minute by minute, what you get and you stop receiving? Applications, so to know "what's new", continuously connected to your server, consuming excessive data and battery (pull technology).
To avoid this, reconfigure your applications and reduces the frequency of automatic updates or choose the manual update. And if you push notifications option, which is the server who reports to your news, please activate it.
You probably also be of those who are watching tic time on the constantly moving. Continuous on and off the phone screen to see the time spent a lot of battery.
But surely, consuming more unlock and lock the phone for any nonsense. Try to control that impulse, it is bad for the health of your battery.
Smart phones have a feature that often lacks intelligence on their part. The automatic locking. Disabling it is a good idea. How many times have you be reading mail and the screen goes blank? Lock yourself mobile when not in use.
6. Strengths and weaknesses of the "task killer"
The latest phones have the advantage of being multi-tasking. That is, they can work in several programs open at once, which can play Angry Birds while the web browser is open in the background. For this reason, remember to close applications when you finish using them.
In Android there called "task killer" (such as Advanced Task Killer) applications that handle automatically close any open process that is not in use. If configured properly, it works like a charm, but if you let work arbitrarily, the remedy will be worse than the disease.
You really need to continuously close your widget Whatsapp or weather information? We recommend that you put an exception to your "task killer" applications that you use regularly, since the simple close-open only if the application remains open in the background spent. Do not underestimate the way that the Android system processes work, do not force him to close tasks that need to be open continuously.
7. Other options to configure
Surely your phone has features that use a lot of battery without your knowledge. For example, sound vibration or pulsation consuming more than you think. Or that the screen rotate automatically when you put the mobile landscape. You really going to notice if you disable these options?
Another absurd spends much battery option, although it seems contradictory, is the "power saving mode". We do not know what they mean to spend less energy, but we know that let mobile constantly control what does and does not do is save, but an additional expense.
The same is true of the wonderful animated backgrounds but wasteful display the latest versions of Android. Yes, your Hello Kitty moves around the desktop every time you look very nice, but a static background will spend much less.
