While some Apple customers have vocalized feeling constantly at odds with the battery life of the iPhone 5 and 4S, there are a few things you can do to get more juice from your charge.
1. Lower your screen brightness -- Just like on your laptop, you can lower the screen brightness on your iPhone to increase battery life. Just head to Settings, Brightness to adjust.
2. Use WiFi where you can -- Instead of downloading apps, making Google Voice calls or browsing the web over your cellular or 3G connection, find a WiFi hotspot or use your home's WiFi network instead. This will keep your data charges down and will improve HP COMPAQ Business Notebook NC6400 Battery Life since your phone won't be searching for a data signal. Keep in mind -- if you are in an area with absolutely no WiFi, turning it off will help save battery life too.
3. Block GPS tracking in apps -- If you're using lots of apps that include automatic GPS location and tagging (a la Facebook, Instagram and Twitter), your phone is working overtime to locate you. If you don't need to geotag your posts and updates, keep the GPS off.
4. Turn off your iPhone's "Fetch" and "Push" -- I have my iPhone set to "fetch" my data every 30 minutes and a ton of apps set to push new messages and alerts as they happen. This is great for keeping up with news and messages when I'm at home, but bad for your data and battery. To turn your "fetch" functions off on your iPhone, just go to Settings, Mail, Contacts and Calendars, Fetch New Data, Manually. You can also turn off your email and calendar "push" from this screen. To turn off app "push" notifications, head to Settings, Notifications, then switch to off.
5. Keep Notifications In Check -- To improve Acer AS07B41 Laptop Battery standby time, limit your app notifications to only those apps you actually need. That means saying "no" to requests for notifications from games and other apps that request the feature -- unless you know the alerts are important. Notifications can be granularly controlled in the Notifications section of the Settings app.
Hope above iPhone battery life saving tips would be helpful for your mobile life!
