How to improve android battery life

android battery tips

1. See what's sucking the most juice.

 Navigate to Settings > Battery to see an organized breakdown of what's consuming your phone's battery. Applications and features will display in a descending list of battery hogs. If you see an application you barely use or a feature you never use, you'll want to uninstall the app or turn off the feature.

2. Reduce email, Twitter, and Facebook polling. 

Set your various messaging apps to "manual" for the polling or refresh frequency, just as a test, and you'll instantly extend your device's battery life by a significant amount. Once you see what a difference that makes, try re-enabling just the most important ones, and possibly reducing their polling frequency in the process.

3. Turn unnecessary hardware radios off.

 It's great that today's phones have LTE, NFC, GPS, Wi-Fi, and Bluetooth, but do you really need all five activated 24 hours per day? Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast. If your phone has a power control widget, you can use it to quickly turn on/off GPS (the largest power drain), NFC, Wi-Fi, Bluetooth, and LTE. On stock Android, swipe down to bring up the Notification bar, and then tap the icon on the top right corner.

4. Use the extra power saving mode if you have it. 

The aforementioned Galaxy S5 and HTC One (M8) both have Ultra Power Saving and Extreme Power Saving modes, respectively, that limits the phone to texting, phone calls, Web browsing, and Facebook. This can squeeze extra hours or even a day of standby time out of just a few remaining percentage points of battery.

5. Trim apps running in the background.

 From Settings > Apps, swipe to the left; you'll see a list of apps that are currently running. Tap on each one to see what they're for; you can stop any apps that you don't need running in the background all of the time.

6. Dump unnecessary home screen widgets and live wallpaper.

 Just because they're sitting on the home screen, seemingly inactive, doesn't mean they're not consuming power. This goes for widgets that poll status updates in the background, as well as ones that just sit there but look pretty and animated—not to mention animated live wallpaper. (But don't dump everything, as part of what makes Android great are the home screen customizations; just remove the ones you don't use.)

7. Turn down the brightness and turn off Automatic Brightness.

 It's probably obvious at this point, but you'll be surprised by how much this one alone helps to improve battery life.

8. Update your apps.

 Applications often get updated to use less battery power, so you should make sure your apps are up to date. Even if you configured the phone for automatic updates, some apps still require that you manually install updates. Check for app updates in Google Play by hitting the menu key and going to My Apps.

9. Keep an eye on signal strength. 

If you're in an area with poor cellular coverage, the phone will work harder to latch onto a strong-enough signal. This has an adverse effect on battery life. There's not much you can do about this one, but keep in mind that this could be the culprit behind a seemingly weak battery; it's worth popping the phone into Airplane mode if you don't need data or voice calls.

10. Check the reviews. 

We conduct battery life tests on every single Android phone we review. Unsurprisingly, the results vary widely between handsets, even on the same network. When choosing a phone, make sure that real world talk time is sufficient. You can't go by what the manufacturer says; we see variances on the order of several hours of usage in both directions on a regular basis.

11. Buy a battery case or larger extended battery. 

Battery cases combine a hardware enclosure, which protects your phone, with an extended battery that can double your phone's endurance. You can find models compatible with popular Android phones from a variety of manufacturers, such as the Mophie Juice Pack and Incipio Offgrid Battery Backup Case (both for the Samsung Galaxy S4).

Best ways to Hide Files and Folders in Android

Today Mobile phones have become an important part of our lives. We seriously cannot live without them for a single day. These devices are not just used for making calls and sending messages. They are also used for entertainment.Mobile phones have also became as a storage device, where we can store our files like documents, images, videos and audios. There are many uses of this little device.
Many people store their important documents, images, music and videos on their mobile phones. Some of the files can be very private and not to be accessed by others. We want to keep them private hidden from others. In Android, when you store images and videos on your SD card, it scans all the files and displays your images and videos in Gallery application. The problem is they can be easily viewed from there.

How to Hide Files and Folders in Android :

Now what can you do to hide your files and folders from others. Today I will show you four methods to do this. First three methods doesn’t need any software. Fourth method is by using third party applications.
Almost all the android phones comes with an inbuilt file manager. But the file manager that comes inbuilt has only basic functionality. Some phones have some additional file managers like X-plore, ES File Explorer or My Files. They have more features.

Method 1 :

Open any file manager like I have mentioned above. If you don’t have, I will give links to download them from play store.
Download X-plore
After opening the file manager, Go to the folder you want to hide. Just long tap the folder and select Rename option. Add a dot (.) before the folder name. For example, if the name of the folder is Videos, just rename it to .videos and click OK. Your folder is hidden. And you won’t be able to see it in Gallery application. By default all the folders starting with dot will be hidden in android. So to view them, you have to go to File manager’s settings and select the option to Show Hidden Files. This option may be different in different file manager. To unhide the folder, just remove the dot from the folder. Now it will be shown in Gallery.
Note that this trick works only on folders not files. If you want to hide files, then create a folder and copy all your private files in it and follow the method.

Method 2 :

The second method is also very simple. Just go to the folder which you want to hide. Open the folder and create a new text file. Leave the file empty. Do not write anything. Save it with the name as .nomedia
If you do not know how to do this, just download the .nomedia file from below link and place it in the folder which you want to hide.
A .nomedia is a blank file which is generally placed inside a folder to hide its contents in gallery. Android scans all the folders and when it finds a .nomedia file in a folder, it doesn’t scan that folder and the contents like images, audio and video is not shown in the gallery application.
In this method the folder is not hidden but the contents are hidden in gallery. But in previous method the whole folder disappears. And this trick is not for files, it works only on folders. So as you have done in previous method, just copy all your private files in a folder and copy the .nomedia file in that folder.

Method 3 :

This is the method which I generally follow. It is as simple as ABC. You just rename the file with an extension which your android phone cannot open. For example if you android file doesn’t recognize .zip extension then you can use the method. Just rename the file with .zip extension. If there is an image file with name mypic.jpeg, then rename it to mypic.zip and move it to a different folder to see the effect. If there is a video file with name myvideo.mp4 then rename it to myvideo.zip
Note that this trick is for only files and not for folders. And also note that files are not hidden, they are just not shown in gallery application.

Method 4 (Using Third Party Applications) :

Third method is to hide files and folders using third party applications. There are lots of android apps available in Play Store which are used to hide files and folders with a password. You can use them if you want a full protection and if you are afraid that the above tricks might be known to others and they can view your files.
You can download your favorite folder locking application from play store by clicking the below link :
You can follow any of the above four methods to hide your files and folders in android phone.
Note :
1. If you are seeing the hidden files in gallery after following the above method, then just move the folder to other location and then move it back to the same location.
2. In third method, you can use any extension that is not recognized by your android phone.
Hope you liked the trick. If you find it useful, please like it and share it on your social networks.

Speeding up and strengthening HTTPS connections for Chrome on Android

Speeding up and strengthening HTTPS connections for Chrome on Android:
Earlier this year, we deployed a new TLS cipher suite in Chrome that operates three times faster than AES-GCM on devices that don’t have AES hardware acceleration, including most Android phones, wearable devices such as Google Glass and older computers. This improves user experience, reducing latency and saving battery life by cutting down the amount of time spent encrypting and decrypting data. 

To make this happen, Adam Langley, Wan-Teh Chang, Ben Laurie and I began implementing new algorithms -- ChaCha 20 for symmetric encryption and Poly1305 for authentication -- in OpenSSL and NSS in March 2013. It was a complex effort that required implementing a new abstraction layer in OpenSSL in order to support the Authenticated Encryption with Associated Data (AEAD) encryption mode properly. AEAD enables encryption and authentication to happen concurrently, making it easier to use and optimize than older, commonly-used modes such as CBC. Moreover, recent attacks against RC4 and CBC also prompted us to make this change. 

The benefits of this new cipher suite include:
  • Better security: ChaCha20 is immune to padding-oracle attacks, such as the Lucky13, which affect CBC mode as used in TLS. By design, ChaCha20 is also immune to timing attacks. Check out a detailed description of TLS ciphersuites weaknesses in our earlier post.
  • Better performance: ChaCha20 and Poly1305 are very fast on mobile and wearable devices, as their designs are able to leverage common CPU instructions, including ARM vector instructions. Poly1305 also saves network bandwidth, since its output is only 16 bytes compared to HMAC-SHA1, which is 20 bytes. This represents a 16% reduction of the TLS network overhead incurred when using older ciphersuites such as RC4-SHA or AES-SHA. The expected acceleration compared to AES-GCM for various platforms is summarized in the chart below.
Encryption

As of February 2014, almost all HTTPS connections made from Chrome browsers on Android devices to Google properties have used this new cipher suite. We plan to make it available as part of the Android platform in a future release. If you’d like to verify which cipher suite Chrome is currently using, on an Android device or on desktop, just click on the padlock in the URL bar and look at the connection tab. If Chrome is using ChaCha20-Poly1305 you will see the following information:

android certificate information

ChaCha20 and Poly1305 were designed by Prof. Dan Bernstein from the University of Illinois at Chicago. The simple and efficient design of these algorithms combined with the extensive vetting they received from the scientific community make us confident that these algorithms will bring the security and speed needed to secure mobile communication. Moreover, selecting algorithms that are free for everyone to use is also in line with our commitment to openness and transparency.

We would like to thank the people who made this possible: Dan Bernstein who invented and implemented both ChaCha/20 and Poly1305, Andrew Moon for his open-source implementation of Poly1305, Ted Kravitz for his open-source implementation of ChaCha20 and Peter Schwabe for his implementation work. We hope there will be even greater adoption of this cipher suite, and look forward to seeing other websites deprecate AES-SHA1 and RC4-SHA1 in favor of AES-GCM and ChaCha20-Poly1305 since they offer safer and faster alternatives. IETF draft standards for this cipher suite are available here and here.
