Battery Extending apps for Android

March 20th, 2011 by Derek Anderson Leave a reply »

I am currently trying out some battery extending apps for the Android platform. Juice Defender and Green Power Free.

A battery extending app, as far as I can tell, shuts off certain functionalities of your device when they aren’t needed. Chief among them would be the data connection.
When you aren’t using your data connection (wifi and 3G/4G)…it still uses power to maintain connectivity.

You may wonder how you will get notified of new mail or messages when the data connection is disabled. The app I am currently testing (GreenPower Free) keeps the data connection off for 10 minutes. Then it will turn it on for a minute so your device can sync with any push type data you may have received.

If you are needing to be updated more often than that, maybe a battery extending app isn’t for you. I haven’t had any problem with notifications or email showing up when I needed them.

JuiceDefender
I tried this app out first and I immediately noticed an increase in battery life. This was great! However, I had a couple of incidents where I had to manually restart the data connection by turning on and turning off ‘Airplane mode’. Since I only have one Android device, I can’t rule out that it may be device related instead of app related.

For even more control than is offered in the Free version of JuiceDefender, there’s UltimateJuice! for $4.92 This basically unlocks more features in JuiceDefender and would be needed to get the most out of this app.

Features*:
– 5 Preset Profiles (from default mode to full customization)
– Easy and Intuitive User Interface (no annoying ads!)
– Home screen Battery Widgets
– Mobile Data toggle automation
– 2G/3G toggle automation**
– WiFi toggle automation + Auto-Disabling option
– Location-aware WiFi Control (e.g. enable WiFi only at home/work, disable it otherwise)
– Battery Consumption Optimization (e.g. when screen off, battery under threshold, etc.)
– Comprehensive Connectivity Scheduling (regular schedule, night time/peak time, week days/weekends)
– Connectivity Control for Specific Apps
– CPU scaling when phone is idle**
– Full Activity Log
– It’s FREE!
* Some features require UltimateJuice.
** Might be unavailable if not supported by your ROM
— Gingerbread not fully supported YET —

Green Power free
This is the app that I am currently using and based upon my experience so far, it will be the app that I would choose to keep.

I took my phone (HTC Hero) off the charger this morning at 7 am. It is now 4:30 pm and after moderate use all day, I have only dropped 1 bar on my battery meter. This is fantastic!
I normally could expect to be at half battery by this time of day and getting re-charge warnings around 8 pm this evening. I don’t foresee this happening today.

Features:
* Supports most phone types (including CDMA) and most carriers
* Keep wireless (wifi and/or mobile data) OFF most of the time to save power
* Fully configurable time intervals and settings
* Toggle wireless ON regularly to update push data (e.g mails, weather…)
* Toggle wireless ON when Screen turned ON, or unlocked
* Toggle wireless ON when Power connected
* Checking traffic before turning OFF to prevent disturbing other apps
* Very lightweight and fast app
* Easy and clean interface

There is a ‘Premium version of Green Power that eliminates ads and allows you access to a ‘night mode’. This Premium Green Power is $1.61.
