[HTC One X] lcampori:
Hi everyone

I'm new here on HOX, coming from samsung galaxy. Battery is a problem with every device, I though it is interesting for everyone to share my experience with sgs and how I passed it on HOX. It is important to state that battery drain gets in the way mainly when you're not actively using the phone. So my task is to reduce drain while having services up when needed. HOX is way better than sgs at this regard with the same settings.

I'm a massive tasker user, I do agree with OP that using it is the best way to minimize battery drain.

To take the most out of it, phone must be rooted, google for "tasker wiki" for details.

1 - Location services and gps are triggered only when needed. In tasker you can condition settings on a list of apps. Be aware than you also need to install securesettings as a tasker plugin to accomplish that, and that weather widget cannot be updated (unless you also condition the location services on screen usage, I did not try that). Phone must be rooted to install securesettings and its helper. Use this with maps, navigation (navi is a little bit trickier, search on tasker wiki)...

2 - Tasker lets you determine you position even with location services off by linking your position with the cell tower you're connected to. So when you're near a given tower, you can trigger an action or setting. I use that to trigger wifi when I'm home or office.

3 - Tasker lets you set the cpu clock or governor conditional to the apps you're using. I use a lower frequency as normal, and raise it just for power-hungry apps. Once again, securesettings plugin is needed and phone must be rooted. (not tried this one on HOX yet, will try with 1.2ghz as default if interface stays smooth and fast).

4 - Unfortunately unless you're using cm7+ roms, it is not possible to automate g2/g3 toggle, so I always leave g2 as default and switch manually to g3 when needed. Phone continuously scanning for mobile networks heavily affects battery consumption.

5 - At night, tasker triggers a time task to set either airplane mode or radios off (wifi, data, bt...). Airplane mode is simpler, but what if a wonderful woman needs you right in the middle of the night and cannot give you a call???

6 - Bluetooth is always off, tasker turns it on only when connected to any power source or I turn it on manually when I need it. If it gets a bt connection with another device it stays on, otherwise it automatically turns off within 1 minute. I do not have to remember to turn it off manually.

7 - Juice Defender is good for battery control, but it disables real time updates (mail, whatsapp, etc). Up to you to use it or not. I don't.

8 - I do not use data hungry widgets or syncs. Facebook or Twitter or whatever.

9 - Set new wifi notification off. If I need a wifi network to connect to, I do it manually. Wifi connection does not drain a lot of battery, wifi scan does. See #10 also.

10 - On sgs, I set wifi scan interval to 150sec instead of default 15s by editing build.prop but I do not find wifi supplicant setting in HOX build.prop.. Root needed.

11 - to get a faster gps fix, I edited gps.conf file by replacing north-america with europe. waaaayyyyy faster. Root needed. BTW, gps fix is miles ahead in respect to sgs. To have a fast gps lock with sgs, an hardware fix was needed. I was brave enough to try and succeded, but it was so dangerous...

12 - and OP suggestions of course :)

I'm getting extremely low drain while having on anything I need at the same time.

I've no figures yet, it's to early since I've got my HOX four days ago. They would not be very robust.

But while I'm VERY new to HOX , my feeling is that it has a great battery life when properly set.

I hope that's useful for you guys.
