[APP] ShutUpBatterySaver -- APN/Autosync ctrl based on SignalStrength & Time

wjax · Jul 18, 2010

Well guys,

It's been a long time since I realized my Nexus ONE was draining a lot of battery.
After some testing I figured out one of the most probable causes for that, Autosync.

So I started creating a proof of concept app in order to run autosync at a specified custom time.

On the other hand, I read some users in this forum talk about the possibility to monitor Signal Strength and disable APN if under a given threshold... so I did it (and added Autosync control on low signal too).
It is very useful when you work all day in low signal areas (as me).

Remember.. this is just a proof of concept... may fail a lot or never!

Search for it in the market!

Enjoy

IMPORTANT: Dont kill the app! Exclude it from memory savers (automatic tasks killer). And dont worry about memory or CPU use, it is negligible.

Update 23/08/2010
New Version 0.2. Hope you like it
You have to unistall the previous one (if not it won't install) because I lost my previous certificate

Interesting...will be testing

Markdental · Jul 18, 2010

What a great idea!

But does this app use a lot of battery monitoring the signal strength and adjusting for this?

kingofyo1 · Jul 18, 2010

will this work on other phones too or just nexus at this time?

First testing i was able to change settings but it seems to fc on me. Using htc hero cdma on darchdroid.

It works perfectly on HTC Hero GSM in Spain with the android 2.1.
So I don't know... I don't have an American Hero.

It should work on every android 2.1 and 2.2 phone...

Dont worry for CPU(battery) drain.
When using Scheduled Autosync it just uses a few miliseconds of CPU for each Loop.

And for the Signal Strength monitoring, it checks it every 10 minutes and only uses (again) a few miliseconds.

If you have Spare Parts, you can check it yourself!

Wow! I instantly noticed a difference in drain even when monitoring it with adb. I'm impressed. What are you guys settings looking like? I am not sure how I should set it up. If I set the sync on for every 25 minutes, does that mean my phone will ONLY auto sync every 25 minutes? This app is long overdue! Thanks!

on my nexus if I leave the app and click on it again on the drawer, the app resets everything (settings, logs)

Yeah, would love to hear some other users' settings that are working for them.

Like maybe the cutoff for the signal strength level.

also, am I suppose to leave sync off?

congratulations for your job. anyway i have an issue with my nexus one. the app semms to work for about 5sec then all the settings are reseting and apn and sync are switching on even if my signal is below my previous settings. do you have any idea?
thank you.

Woo! I'm glad my thread on turning off data when signal is low actually made it into something! I'll try this out soon...

I would also like to know if I should be leaving androids built in auto sync off or leave it on? So far, I have been getting great battery with this set to
Sync options:
30min off
2 min on

Signal options:
-104dBm
-104dBm

I can't wait to see where this is going!

I also can't get my settings to save.. just resets after I exit the app.

Why are you reseting the app?
I mean, the app is meant to be always alive.

You should never kill it and exclude it from any memory saver task killer that you have. Otherwise it cannot work!!

Dont worry about leaving it alive as it only uses a very very small time of CPU.

Sooo... Dont Kill it!!

Just let me know your results

wjax · Jul 19, 2010

I am currently using:
- Autosync due to Timer 1h - 3m
- APN off if Signal less than -90dBm

It works nice!

Anyone think this would conflict badly with juicedefender?

I'm not using JuiceDefender anymore because it just seems to mess too many things up. That's just my experience though.

Should we be leaving the regular autosync on or off?
