App: Setting Profiles in Android phone with MyProfiles

Profile setting and management has been a must-have feature in all mobile phones since long time ago, even before smart phones available in the market. This function allows us to quickly change multiple settings in the phone to specific need, such as set it to Silent Mode in cinema, Battery Saving Mode at night, etc.

However, this basic function doesn't come by default in Android, and we have to install the 3rd party application from Android Market in order to have such function in our Android phone.

I find MyProfiles developed by Fancy01 Inc. in Taiwan to be the best in terms of user friendliness, easy to use and good user interface, although it isn't the one having the most comprehensive features. Its operation doesn't consume much battery too.

MyProfiles lets us define an unlimited set of profiles and name them accordingly. Here are the profiles I set in my phone.

MyProfiles provides 40 over icons for us to choose and associate to the profiles we set, which is pretty sufficient.

For each of the profiles, we can define the settings of:

• Sound volume for ring tone, media, alarm, notification, in-call and system
• Sound effect / music for ring tone, alarm and notification
• Vibration
• SMS notification handling
• Auto answering
• Auto speaker on
• Screen display timeout
• Auto lock timeout
• Airplane mode
• WiFi
• Bluetooth
• Mobile network
• Auto Sync
• WiFi hotspot
• GPS
• WiMAX
• Mobile data connectivity
• Display brightness
• Screen auto-rotate
• ... and more

After the Profiles is setup, they can be switched into until the next toggle, or switched temporary for a period of time, then fall back to the settings before the switch.

The temporary mode will be handy in situation such as: we know a movie will be ended in 2 hours time, so we set our phone to be in Silent Mode for 2 hours and let it auto-revert back to its previous state.

We can also schedule for a certain profile to be triggered during certain time period.

Currently, MyProfiles still lack of features such as location based auto profile switching, car motion (> 20 km/h) auto profile switching, battery state profile switching, cable connection (and/or charging state) profile switching, etc.

MyProfiles development is pretty dynamic, with new release coming out at least once every week. Fancy01 is also very responsive to emails sent to them.

MyProfiles comes in 2 versions, the free MyProfiles Lite and the paid MyProfiles. Its price at US$1.49 (increased from US$0.99 since 28 April 2011) isn't expensive and very affordable.

If you own an Android phone and haven't found a suitable profile management app yet, or you find your current profile management app too difficult or tedious to use, I recommend MyProfiles to you.

Battery consumption between GSM (2G) mode and WCDMA (3G) mode

I notice that the battery life of my phone can last longer when it is in GSM (2G) mode than WCDMA (3G) mode.

Here is a simple observation of its battery consumption pattern. I switched it to GSM mode (Settings > Wireless & networks > Mobile networks > Network Mode > GSM only) during day time, and switched it to WCDMA mode (Settings > Wireless & networks > Mobile networks > Network Mode > WCDMA only) before I slept, and switched it back to GSM mode again the next day. Along the whole period, there is no phone call.

Here is the battery consumption pattern I get:

and here is the same graph shown in landscape view:

It is very obvious that when the phone is on WCDMA mode, its battery consumed faster.

This is an HTC Incredible S upgraded to Gingerbread Android (version 2.3.3). I do notice that when it is in GSM mode, the signal is pretty stable (I can always get a full bar), and when it is in WCDMA mode, the signal is not that stable (there are frequent occasions of losing one bar or two bars). Probably the stability of the signal is one of the major factor in battery consumption.

Anyhow, it is a known fact that the phone will consume less battery when it is in GSM mode rather than WCDMA mode, and it is among the tweaking of battery saving apps such as Juice Defender.

App: Yahoo! Mail for Android is a battery sucker

Yahoo! Mail for Android is an app developed by Yahoo! Inc. to access Yahoo! Mail accounts directly from the smart phone.

There are quite some feedbacks in Android Market complaining that this app is slow, but I didn't experience any obvious slowness in my HTC Incredible S.

Despite that, I've uninstalled Yahoo! Mail because it consumed too much battery, and I couldn't find any setting to fine tune its battery consumption, such as controlling its sync behaviour.

Before I installed Yahoo! Mail, my phone will consume about 7% of battery at night during my sleep. After installed Yahoo! Mail, I noticed the battery consumption had gone to 14%, doubling up the original, and after I uninstalled it, the battery consumption now gone back to 7% during sleep again.

Looks like Yahoo! need to pay more attention to their QA before releasing the app.
