As per my previous post, there have been reports of users getting well over 4 days of standby time from the X10 Mini Pro. I have yet to experience over one day of use with it.
Ok... aside from not using the phone... I've tried to find a combination of apps that will help maximize battery use, without sacrificing too much of the capabilities of the phone.
For people that do not have unlimited data plans, then you're over half way there... having unlimited surfing capabilities really takes its toll on your battery... mainly because you're always surfing... hahahaha... and background sync does drain a lot as well. Leaving it on 3G doesn't, but data polling and push services (if you get a lot of email and facebook updates like I do) does drain a lot.
So far, I've tried a ton of power management apps... and so far... there are 3 that look very promising together.
Juice Defender shuts off cellular data services when your screen goes on standby, and turns it back on when you use your phone. This prevents apps and widgets from connecting to the net and draining your battery when you're not using your phone. Free version logs in every 15 min so email and MMS can come in during those intervals... it might be worth getting the paid version if you want more control over time and scheduled log-ins.
SMODA Widget, a small 1x1 button to shut off data services manually. Can over-ride Juice Defender when you're screen is on and you don't want to surf.
Timeriffic allows you to control and trigger wifi, ringer, screen brightness, vibration, volume, and airplane mode using user set times and days. Like you can have the phone automatically go on silent at 10pm and turn all sounds back on at 6am. Or completely cut-off using airplane mode during Sundays. I personally only use this to control my screen brightness during the day.
There's also an app called Power Manager that enables wifi when you plug in your phone, and disables it when you unplug your phone. This runs in the background, and you can always over-ride it manually.
There are a ton of other apps that can help you manage and save battery life... so far, for my use, Data on Demand seems to be the one with the biggest difference since all I give up are push messages. So it has the least impact on my use, without me giving up too much functionality or convenience (I don't like having to turn things off and on all the time)
What battery savings apps do you guys have running on your Android phones?
***August 7, 2010 - Juice Defender has a widget that performs the same function as the SMODA widget, so if you like Juice Defender (I'm hoping to get the full app when it's available here in the Philippines) you don't need SMODA anymore... but if you just want a simple widget that shuts off your data transfers, SMODA is the way to go***
