[HTC One X] Wilks3y:
Over the last few weeks, I've been looking into the most productive ways of saving battery on my HOX. Please note you don't have to follow this guide Step-by-Step, you can simply pick and choose which tweaks/tips you want to use to try and improve your battery.

Some of the tricks I used, were extremely effective, others have little effect but which ever ones you choose, is up to you:

Before I went about getting the most out of my battery, I made a complete factory reset, to make sure anything left from previously used rogue apps etc, were gone and werent causing issues.

The first thing I did was get Nova Launcer, as I think Nova is clean, smooth and looks very similar to stock Android, which makes it easier to go from my HOX, to my Nexus 7 without getting confused. This is also great if your one of the many out there that aren't a fan of Sense. There are other launchers to choose from, so make your choice:

Nova

Apex

GoLauncher

LightningLauncher

I can only comment about Nova, which uses next to no battery.

For this, I used HD Widgets. Create toggles for your brightness and then use this toggle to set your brightness to a point where you find it nice. I left it at 50%. Also create a toggle to FORCE SYNC.

HD Widgets

Beautiful Widgets

PowerToggles (Free Alternative)

Auto syncing in my eyes, is pretty useless, as everything re-syncs/updates when you enter it, including mail and calendars etc. So I turned most of them off, leaving a couple such as Play Updates. Then, if needsby, use the toggle widget you created earlier and force-sync when you need to.

THE BIGGEST SYNC DRAINER IS FACEBOOK, COMPLETELY DISABLE FACEBOOK's SYNCS, Unless this is important to you !

Goto:

Settings -> Accounts and Sync -> Choose each profile and un-tick any Sync's that you don't use.

For those of you who don't know, Tasker is an EXTREMELY powerful automation tool for your phone, which you can program to do almost anything you wish. Tasker is known to have a learning curve, but I find if you look at it logically you can figure your way around it quite simply. It works like this:

What do I want to happen

What is going to cause it

What I want Tasker to do once that has happened.

Tasker Profile 1 - This has got to be one of the best Tasker profiles I've done yet, as it saved me pretty much 20% battery, A DAY.

Profile One:

Set the Context to - Display State ON

Set a wait period of 10 seconds

Set the Task to - Enable Wifi

Profile Two:

Set the Conext to - Display State OFF

Set a Wait period of 10 seconds

Set the task to - Disable Wifi

The wait is so that when you flick the screen on and off, to check time/date, it doesn't enable/disable Wifi straight away.

Another method of this, to save even more battery, would be to disable WiFi altogether, and then set tasker to enable WiFi by App per App basis (Such as Facebook/Browser/Youtube) etc

Bedtime Ritual?

Some Android Phones/Versions support tools to allow you to disable almost anything between certain times. This is often called "night-mode". This can save rucks of battery, but isnt useful to many as lots of people charge during the night. If your one that doesn't, either use the in-built funtions, or again use Tasker, to disable all features and functions you see fit between the times you sleep and wake up. Such as 12PM to 6AM.

Although I don't use this one much myself, it can make almost a 20% different in battery between GSM and GSM/WCDMA Auto. If possible, changing it to GSM only can save alot of battery:

Step 1: Tap on settings in the notification panel.

Step 2: Then tap on Mobile network and the network mode.

Step 3: Tap on GSM only.

Monitoring your battery, to see whats draining your battery in particular can be a very good method of highlighting, and remove rogue battery eaters etc.

The abolute best tool for this, bar non is BBS (BetterBatteryStats) which monitors Wakelocks etc to see whats eating the battery.

You can find BetterBatteryStats here.

If you like his work and would consider donating find it on the PlayStore.

Alot of people have mail clients on their device, this can range from Exchange servers for work, to personal E-Mails such as GoogleMail and HotMail. These often "poll" for updates every so often (usually 15 minutes) this is an absolute killer for battery, luckily, alot of them now support "Push" notifications. If this is an option for you USE IT.

Widgets are very useful for most users, and alot of people use them. It is also one of Androids main differences to its competitors.

Ditch the Widgets you rarely use, or those that don't make much difference and could be removed in exchange for simply opening the app.

For example FaceBook's widget in my eye's is useless, its just as easy to go to the Website/App and check their. Lets be honest here, people are on FaceBook multiple times a day, whats the use in the widget?

Also, if your like me, everything is kept on the one page, remove all other Widgets from other pages if possible.

Haptic feedback can be an absolute killer to your battery, and is also pretty useless. Haptic feedback basically plays a tone/vibrates each time you press something, so typing "Hello" would cause it to vibrate 5 times. Whats the use? Surely you know when you've pressed it, and also LOOK AT THE SCREEN? to see if you've pressed it.

To Disable haptic feedback:

Haptic Feedback, along with sound feedback, is located under the "Sound" options, at the very bottom. Disable one or both and you will see an improvement.

IF THERES ANYTHING ANYONE CAN ADD TO THIS. LET ME KNOW.
