How to Get 12 Hours Battery Life on Droid RAZR

The uber-thin Motorola Droid RAZR, sold now on Verizon Wireless as an LTE phone and also as a worldwide unlocked GSM phone, claims to be able to get 12 hours of battery life. Achieving the full 12 hours is no easy task, and XDA member royalbloodvi has written a guide for RAZR owners who want to get the most battery life possible from their device.

Use the following settings:

  • 2g & Data connnection off when screen off (For e-mails, let autosync check every x minutes you would like)
  • 3g when specific apps need data connection on (for internet radios enable the screen on/off profile)
  • In-built setcpu function, set min/max to 300mhz on idle
  • Enable juicedefender to automatically handle 2g/3g networks
  • SMARTACTIONS: Display ON & OFF profile -> Disable background sync
  • Juicedefender in-built autobrightness, and tweak the settings below stock brightness
  • Enable juicedefender to manage wifi

Play With Voltages On Your Xperia Neo and Arc With SetXperia

There are several advantages on having a rooted device. One of them is that it allows you to install apps that would otherwise be barred by the device itself. The other advantage is that this allows you to do other fun things like making your device faster and/or more battery efficient. XDA member inteks has released a tool that he was working on for his Xperia Neo. Basically, this is like SetCPU but with a more dedicated focus on the Xperia devices. This program will allow you to change frequencies (overclocking), play with voltages (undervolting), and it also takes some functions from other similar apps like SetCPU, No Frills, and IncrediControl. You have to keep in mind that the heart of these functions do not lie in the app itself but rather in a custom kernel that enables all of these. So, if you have a rooted device running stock kernel, you will likely not be able to do much.

Please take it for a spin. The dev just recently released an updated version with several bug fixes, so please leave your feedback. Lastly (and as always), be careful when you play with the processor settings as this has the possibility of damaging your device.

Do You Have A Wave(Droid) And Would Like to Overclock It? Here Is How…

Well, it looks like development on the Samsung Wave is paying off rather nicely. In case, you haven’t been following the Bada scene, developers have successfully ported Android 2.2 (Froyo) and slapped it on top of Samsung’s proprietory OS in a project called Wavedroid. Well, now that Android is fully functional, tweaking efforts are underway. In this particular case, XDA member ispanecaaaa showed us how to overclock the device to about 1.6 GHz. Most of you Android users will be familiar with this process as it is done with setCPU. However, for this to work properly, a different image must be installed than the original wavedroid one. Also, you need root due to SetCPU being utilized. People have been reporting good results so far and seems to make the device less glitchy and more responsive, but only at lower clock speeds. Some people have also provided Quadrant scores as well as proof of improvement.

The dev provides rather clear instructions on how to achieve this and even links to the wavedroid project thread in case you are not certain on how to get Android going on the device. If you have any feedback or find any bugs, please let the dev know.

This is the tutorial how to overclock our Samsung wave with Android.

First HTC Sensation ROM With Enabled Full Dual-Core Support

Do you know how dual core processors work? They contain two central processing units integrated into one circuit, just think of it as a four-lane highway as opposed to a two-lane one. Dual-core processors can handle twice as much data without making the processors themselves any faster.

XDA Recognized Developer mike1986. presented today the first HTC Sensation ROM capable of full dual-core support. Basically, this means that you will take full advantage of the new processor giving you more smoothness and perhaps a bit more of speed when you are multi tasking on your shinny Sensation. Moreover, the CPU is automatically over-clocked up to 1.83 GHz instead the 1.29 GHz that comes by default. Lastly, the ROM is Android 2.3.4 Gingerbread from the official HTC RUU 1.45.401.2, which includes HTC Sense 3.0.

The developer mentions that the Andreno200 has improved configuration for better quality and performance.

Let us know how this is working for you by leaving a comment.

Plan Your Routes For Future Meetings With This Tasker Profile

Tasker’s quite the powerful little app, enabling such things as taking control of your CPU speeds and Texty notifications. Now XDA forum member and experienced Tasker tutorial writer brandall has put together a very useful guide aimed at displaying the route information and travel time required for your future meetings five minutes prior to departure.

In the words of the author:

Profile Aim

Tasker reads your calendar creating a home screen widget via Minimalistic Text. Reacting to a future ‘meeting’ entry, it queries Google to find out the route information and journey time. Using the journey time information and meeting start time, it calculates what time you will have to leave and loads Sav Nav with the preselected route 5 minutes before you are due to depart.

Now FULLY Functional

Whilst creating the ‘Ultimate Alarm Clock’ I wanted the speech engine to read out the details of my meetings for the coming day from my calendar. I was a little disappointed that Tasker did not yet have the functionality to do that and despite delving into the calendar data base files; I could not find a way to achieve it. Damn.

When Tasker is able to read calendar entries in future releases, the tasks described below can be easily adapted to make sure you have a ready to go profile, but in the mean time, and I hope as always, this tutorial is full of handy Tasker tips and tricks

Continue on to the tutorial thread to further your Tasker-based enlightenment.

Asus Transformer Successfully Overclocked to 1.4 GHz… More to Come!

For those of you who were concerned that the ASUS Transformer was going to be a dead device because of the lack of development on its forums, you should drop by and check out some of the latest developments, particularly the latest, which is courtesy of XDA member netarchy. The dev has been working for a few weeks on a kernel that would allow to do more with this tablet from ASUS. Long story short, he recently released a kernel that allows the device to run at a blazing fast 1.4 GHz, as opposed to the stock speed of 1 GHz. The dev does warn that the 1.4 GHz is still a bit unstable, which makes this kernel not 100% ready for mass consumption. However, if history is any indication, running unstable or otherwise experimental software on our devices is not something that has ever stopped us from trying to get the most out of our devices. There is also a second frequency set at 1.2 GHz, which some members have reported as being far more stable than 1.4 GHz. One of the added bonuses of this kernel is the fact that choppiness is almost completely gone from the Youtube videos at either 720p and 1080p. Also, despite the high frequency used, it seems that the kernel is rather gentle on battery consumption as well (not that the Transformer has lousy battery life or anything). Members have reported Quadrant scores of up to 4900 and a few others (me included) have experienced a little over 4300 with Linpack scores of over 58 MFLOPS.

If you have one of these and would like to take this kernel for a spin, please leave feedback.

Current things of interest:
– Overclock up to 1.4ghz (this will probably expand later) [Use a tool such as Setcpu to overclock]
– 2.6.36.4 kernel base
– CIFS included
– TUN built-in
– NTFS support

Rooting and Overclocking for Noobs – Chad Hughes – XDA TV

The Fast Gets Faster – SGS 2 Overclocked

Lots and lots of people worldwide are claiming the Samsung Galaxy S 2 as a fantastic piece of mobile technology. Slim, good looking, and packing quite a punch under the hood, some would even say that it is one of the best phones out there. Well, if there is one thing that is a universal truth around XDA is that there is always room for improvement.
XDA member coolbho3000, whom you may remember from a relatively unknown app called SetCPU as well as many of the overclocks done for most phones, has managed to take the SGS 2 to a whooping 1.504 GHz, making it faster and snappier, and yielding Quadrant benchmark scores of over 4000 (I am fully aware of the fact that about half of you out there will say that the scores mean nothing, yet… it is impressive). The dev was actually able to take the OC to an unstable 2 GHz as well as a quasi unstable 1.8 GHz. The problem though seems to be that the phone runs at very high voltages and temperatures at these speeds.

If you are interested in taking this for a spin, the dev has posted a very complete guide on how to OC this device. As always, remember that there is always a risk when overclocking hardware.
Please leave some feedback.

I have successfully overclocked the new Samsung Galaxy S II to 1.504GHz. This speed is enough to allow it to achieve really high benchmark scores like over 4000 points in Quadrant! 1.5GHz is a 25% overclock and makes this fast phone even faster and snappier in day to day usage.

I haven’t gone crazy on the voltages – 1.504GHz is stable at 1375mV on my device. Depending on your device, there may be even more headroom. I’ve gotten speeds of up to 2GHz to boot with instability (my unstable 1.8GHz Linpack run is currently in the Linpack top 10), but at very high voltages and temperatures. Leave it up to other developers to give you higher/more dangerous frequencies and voltages. If you stress the CPU a ton the phone will become hot to touch (though it does to a certain extent even at stock frequencies – there is not much thermal insulation between the processor and your hands in such a thin phone).

The Weekly Q&A: Week 35

As part of our regular Q&A session here on the XDA-Developers portal, I’ll be covering some questions and issues frequently seen here in the world of XDA.

Q: I have a little headphone icon showing up in the system tray, and I have no idea why, or what exactly it means is happening. [Question originally seen in the Motorola XOOM Q&A Section.]

A: While the notification pops up at seemingly random some times, this is nothing to be alarmed about. Honeycomb simply places a headphones icon in the notification area to let you know that the Music Player app is running in the background. Sometimes, this is triggered by disconnecting headphones or removing the tablet from the dock.

Q: I don’t know what happened but yesterday after i restarted my N1, most of my apps on SD Card couldn’t seemed anymore! Apps are on the list, on the desktop and on the apps settings (without original icon). But my system doesn’t connect apps on my sd card. [Question originally seen in the Nexus One Q&A Section.]

A: It’s quite possible that the SD card has become corrupted. XDA forum member habs25 had a similar experience and was able to solve his woes with CHKDSK built into Windows. If that fails, a low level format of the SD card and reinstalling the old applications should do the trick.

Q: I want to be able to plug my DSLR camera directly into the USB on my Xoom and download the pictures. Is this possible if I root and use the new Tiamat Kernel? [Question originally seen in the Motorola XOOM Q&A Section.]

A: While you currently cannot connect a camera directly to the XOOM to download images (unless your camera supports USB Mass Storage mode), the easiest way to do this would be to use a USB card reader with your XOOM. An excellent guide is available in the forums on how to use USB Mass Storage with things like card readers and thumb drives.

Q: I was streaming a tv show and paused it and turned the screen off to answer a phone call. After about a 10 minute conversation i went to turn it back on and nothing. Holding down the power button doesn’t do anything. I plugged it into the charger and nothing also. I am rooted with custom kernel installed with SetCPU to scale all the way up to 1500 MHz. It’s been overclocked for a few weeks. When streaming I did notice it getting a couple degrees over 100 fahrenheit but didn’t think that much of it cuz my EVO can get a lot hotter. I didn’t buy a warranty through Best Buy, so I haven’t checked what their return policy is. I’m sure Motorola has some sort of warranty which I KNOW I voided with the rooting and such. What should I do? I’ve only had this thing for less than a month. It’s the wifi only version. [Question originally seen in the Motorola XOOM Q&A Section.]

A: As XDA forum member Rajones19 points out, “Might have just been a lock-up. Did you try to reboot it by holding down Power and Volume Up? That’s saved me a few times when things came to a crashing halt.”

Q: We have no lanyard hole in the Nexus S. Any ideas how to attach it? [Question originally seen in the Nexus S Q&A Section.]

A: Unfortunately, there really is no place to attach a lanyard to the Nexus S. While you may be able to thread a lanyard through the speaker holes in the removable battery back, we don’t recommend it… That is, unless you want your phone going flying at the slightest tug. But hey, that would keep your battery back from hitting the ground with catastrophic fury!

That about wraps it up for this week’s session. Stay tuned for more news and Q&A sessions! As always, if you have any suggestions for stories or questions that we should cover, please feel free to send me (or any other News Writer) a private message.

 

Keep Tabs on Your CPU’s Frequencies With CPU Spy for Android

If you are into playing with the settings that control the hardware and performance of your Android device, you are more than likely familiar with overclocking applications like SetCPU. Having said that, you probably have set a nice profile that would give you great performance as well as great battery life. However, do you know exactly what your processor is actually doing? XDA member storm717 had this idea that he put into an application where he could monitor the frequencies at which the processor runs at any given time and more importantly, for how long. The app will also display information as to which kernel is being used. Information like this can help end users evaluate kernels even before trying them.

Give this app a shot and as always, if you are overclocking your device, be careful as it has potential risks associated with doing this. Please leave some feedback.

Created a simple app to display the time the CPU spends in each frequency state and the current kernel build. May be useful to some… especially people running OC’ed kernels.

Also useful to confirm which kernel you’re currently running.

You can find more information in the application thread.

Harness The Power of OCD on Your Android Smartphone’s OC

If you’re anything like the rest of us ORDers, you’re a fan of XDA forum member coolbho3000‘s wonderful SetCPU utility. However, while SetCPU lets you create and specify over-clocking profiles, the list of profile entry conditions is a bit sparse.

Luckily, Android’s many automation utilities excel at creating and executing condition-based commands. Using Tasker as his reference, XDA forum member brandall has compiled all of the relevant information that you need to get started with profile-based CPU control.

This thread is to show, assist and learn (from your input) how to fully utilise the newly introduced CPU controls, with the ultimate goal of preserving battery life without using additional applications such as SetCPU or other power saving scripts.

Does this sound interesting to you? If you have even a smidgen of ORD, be sure to continue on to the tutorial thread to get started!
