5. Monitor “Running Services”: Since Android allows multitasking, applications can run in the background even when you’re not actively using them. Keep an eye on the services that are running in the background, because you may have apps running in the background that you don’t need that are using your phone resources and battery. You can see which services & applications are running in the background & terminate them by going to Settings > Applications > Running Services.
6. Disable “Always-on Mobile Data”: Turning this feature off reduces power consumption by only using 3G/4G radios when they’re needed to sync with your accounts instead of always having them active. This is not the same as turning the 3G/4G radios OFF; the radios will automatically turn on when your phone needs them (for example, to check email) – they just won’t be on and wasting power all the time. To disable ‘always-on mobile data’ Go to Settings > Wireless & networks > Mobile networks & un-check “Enable always-on mobile data”. We haven’t found any downsides of disabling this feature, as Gmail and services still sync properly.
3. Turning off wireless services: Turning off wireless services that you don’t need will save a lot of battery power, as each service has its own radio which consumes power even when you’re not using the wireless service. If you’re not in a 4G area, turn off 4G so that the phone doesn’t waste battery power searching for a 4G network that doesn’t exist where you’re at. Same goes for WiFi, Bluetooth, and GPS – if you’re not using them, turn them off!
While turning off WiFi is a great idea if you’re not using it, if you ARE frequently connected to WiFi you may want to change the WiFi sleep policy to “never”. This may sound like a bad idea, but by default your WiFi connection will enter sleep mode after 15 minutes of inactivity and your phone will then switch to 3G/4G connectivity, which uses more power than WiFi to sync, check email, and retrieve other data. You can change the WiFi sleep policy by going to Settings > Wireless & networks > Wi-Fi Settings. Press the Menu button and tap Advanced, then select “Wi-Fi sleep policy” and choose “Never”.
4. Manually Turn Off Your Screen: Even if you have your screen timeout set to 15 seconds, you can squeeze more battery life out of your phone by turning off the display manually as soon as you are done using your phone for the moment.
1. Screen Brightness: Considering that the EVO 4G has a very large screen, the brightness level can significantly impact your battery life. You can adjust the brightness of the display by going to Settings > Sounds & Display > Brightness (under “display settings”). You can also set your EVO to automatically adjust the brightness, which will automatically adjust the brightness depending on your current lighting conditions.
2. Lower Screen Timeout Setting: After you aren’t using the EVO for a specified amount of time, it will automatically turn off the display to save battery. You can change this setting to 15 seconds, 30 seconds, 1 minute, 2 minutes, 10 minutes, or never. Obviously, your phone uses more battery when the screen is on than when it’s off, so changing this setting to the lowest one is a great idea. If you are constantly using your phone throughout the day, changing the timeout to 15 seconds really adds up and can save a significant amount of battery time. This setting can be found by going to Settings > Sounds & Display > Screen Timeout.
4. The LCD Screen
Another battery life drainer is the LCD screen on the back of your camera. These screens need energy to light them up, and are usually turned on whether or not you’re taking a photograph. This can be a huge drain on battery life, and isn’t always necessary if your camera also has a viewfinder.
The catch for this trick is to dim or turn off your LCD when not in use. The setting can be easily found in your camera’s menu or settings page.
5. Using Flash Sparingly
Flash acts as sonic boom, crunching through your battery life. From time to time, you always see someone using flash to photograph a subject 100 meters away from them (at a concert, for instance). Let me tell you – in this situation, using flash will not increase the exposure of your subject in any way, and the only thing you’re doing is wasting your valuable battery power on flash. Use flash, but wisely and only when necessary.
1. The Start Load
When you start your camera, the starting load is considerably more than what it takes to capture an actual photograph. Some people take photographs at regular intervals, but have a habit of switching off their camera when they feel that they won’t be using it for a few seconds. This practice decreases the battery life significantly, and should be avoided.
2. The Lens Movement
Many of us use point and shoot cameras for our day-to-day photography, and the most battery consuming thing in these types of cameras is their optical zoom lenses. Since these lenses use mechanical parts to expand and contract, every time you do so, it eats up significant amount of your battery charge. Try not to experiment too much with zooming when you’re running low on battery.
3. Standby Mode
Almost all cameras out there have a standby mode as an in-built function. This puts your camera in a state of “sleep” if it senses that the device hasn’t been used for a while. This is not remotely similar to turning off your camera and turning it back on, and the standby mode saves a lot of battery power.
