HTC Android 2.3.3 (Gingerbread) built-in battery reading graph

There are several 3rd party battery metering apps which can draw graph based on battery reading, but if you have recently updated your HTC smartphone to Android 2.3.3 (Gingerbread), your phone actually has a pretty nice built-in battery reading graph within the system. This feature is found in Gingerbread version of HTC Incredible S, HTC Desire HD, etc.

Go to Settings > About phone >Battery > Battery use and you'll see the screen similar to as below.

Note that on top of the screen is a slanting slope with information telling you how much time your phone is on battery since last charged. In fact, that slanting slope is your phone's battery reading graph. Right below the graph you will be able to see some blue marks. Don't worry, they are not screen display problem, but are actually indicators when battery is used by phone activities. If you charged your phone, you will also see green bar plotting the battery charging period.

Tap on it and you will get a clearer graph. The blue battery usage marks are further break down to the respective activity.

If you turn your phone to landscape orientation, this screen will also adjust itself to landscape view.

I think, with this nice battery plotting feature, you don't need to use any 3rd party battery metering apps anymore.

App: Keep an eye on apps that access your private data with Lookout Privacy Advisor

There are quite a number of private data stored in our smartphone, including our identity, contact details, location tracks, address book details, phone call logs, SMS messages, etc.

Do you want to keep an eye on the apps installed in your Android smartphone, to know what kind of private data they are able to access? In fact, these apps get access to our private data because we allowed them so during installation.

Anyhow, we don't want the apps to access our private data unless really needed. For example, SMS application such as Handcent need to access our mobile number, address book and SMS messages in order for it to function, but it should not access our location tracks unnecessarily.

Lookout Mobile Security (Premium Edition) for Android has a handy tools called Privacy Advisor that can scan through all the installed apps in our phone and provide us the insight of what kind of private data they are able to access.

After the scan, Privacy Advisor  will report how many apps has access to our Track Location, Identity Info, Messages and Contacts respectively.

It will list out all the apps with such private data access, and provide detail explanation of the findings.

If we click the "App Info & Options" button, it will go to the phone's application management function, which we have the option to uninstall the app if we want.

I find this feature pretty useful, but it is not available in the free version of Lookout Mobile Security.

App: NetQin Android Booster aka Mobile Guard

If you are using an Android phone, I would like to introduce you NetQin Android Booster (a.k.a. Mobile Guard), which is a utility that can automatically free up memory, monitor network and power usage, prolong battery time, etc. This is an ads supported free app, which you can find in the Android Market.

If you are using S60 Symbian phone, there is also a Symbian version of NetQin Mobile Guard, but there are lots of different from this Android version.

Android Booster comes with a handy widget. With it, you can watch the battery level in percentage, quickly toggle the WiFi, Bluetooth and Mobile Data Network. There is also a one button quick optimizer to clean up running apps and free up memory and save some battery usage.

Although the new Android 2.3.3 (Gingerbread) in HTC Incredible S already has a quick setting page to toggle the WiFi, Bluetooth, Mobile Network, etc., it still involves a few steps to reach there, and I find Android Booster really handy for switching these connections on/off. Samsung Galaxy Tab also has handy WiFi and Bluetooth toggle by pulling down its Notifications, but lack of Mobile Network toggle.

Tap on "Android Booster" will open up the app itself, and tap on the battery will bring you direct to the Battery Consumption Tracker screen of the app.

When you open up the app, you will be shown the Overview screen, which displays the memory usage, mobile data network usage and battery remaining. The same "optimize" button as in the widget is also found here.

The Utilities screen lists down all the functionalities of Android Booster.

Task Manager lists out the running apps and their memory usage, and you can kill them here if you want. This is similar to the famous Advanced Task Killer apps. So with Android Booster, you don't need another Task Killer apps anymore.

Network Manager displays your data plan consumption and WiFi usage, which you can counter check with 3G Watchdog Pro. This is not as comprehensive as 3G Watchdog Pro, but will give you basic information about your network bandwidth usage.

Power Manager (a.k.a. Battery Consumption Tracker) will tell you what is the item that consume the battery most.

If you tap on Applications, it will further tell you which app consume the battery most.

Application Manager enables you to see the listing of installed system apps and 3rd party apps. Tap on the app and you'll be able to run it, show its detail info, and even uninstall it if it is a 3rd party app.

File Manager lets you access the file system of your memory card. You can view the folders and files, and perform functions such as delete, rename, copy, move, share, create new folder, etc.

Call / SMS Manager is another app by NetQin which can block unwanted calls and/or SMS, and also hide out secret SMS and/or call logs.

Location Privacy Manager teaches you how to switch off the option to disable Google from collecting location data from your phone.

As you can see, Android Booster is feature rich, and it is free (but you will see Ads bar at the bottom).
