How to use CPU Tuner in Android Phones

In the following post I will explain how to use cpu tuner, a completely free and open source app for android. All you need is root and some time. It's a follow up on and summary of my various related posts you can mostly see below ("related posts") on working with governors to increase power efficiency in Linux. This is of course something that a) Linux and b) Android and c) your phone manufacturer should already have done. But as they didn't...

0. Notice
CPU Tuner (CT) also includes setting "Min" and "Max" Frequencies. This is meant for devices with special firmware, which allows for overclocking and is not part of this post. All of these steps (tune governors, disable inactive interfaces) apply to any Linux device.
The following goes out especially to our dear US users (but also to every country with punitive damages):
CAREFUL, this tool may cause your phone to explode and other annoying things. You should especially never put your phone into a washing machine, or dryer or microwave or into a fire or do other completely and utterly stupid things with it! Use of this tool does not protect against lack of brain or thought!

1. What is...?
Now let me begin by explaining all the terms used in the program.

1.1. up_threshold: The CPU usage % at which the CPU frequency is scaled up. In the case of conservative this is X % higher than the current frequency. X is determined by the freq_step setting and defaults to 5 % in Linux and 20 % in my android and is not supported by CT atm. In the case of ondemand, (AFAIK!) it skips directly to the maximum frequency. That's why there's no freq_step in the case of ondemand.

1.2. down_threshold: As you may have thought already now, this is the CPU usage percentage where the frequency is reduced. This does not exist for the ondemand governor.

1.3. Triggers: Here you can tell CT that you want to use certian profiles in certain conditions. The most simple condition is battery usage. If battery usage is set to 100, then CT will set a certain profile whenever the battery is below 100%. Another important profile is Screen Off. This allows you to activate a certain profile once your screen is off.
1.4. Profiles: A profile is a combination of settings, e.g. Disable Wifi, Use Conservative Governor, etc. (see 2.1).

1.5. governor: This picks your CPU frequency according to an algorithm (a set of rules). There are different algorithms available:

1.5.1. performance: This stays at the maximum frequency all the time. Not power efficient at all. But great for testing if the problems you are experiencing are really caused by frequency scaling.

1.5.2. powersave: stays at the minimum frequency no matter what. I think this never makes sense. It will take a lot of time to get back out of this as any phone becomes very unresponsive once you set to this, so be careful and just avoid it! Oh, and then some devices just hang without return when you set this. It might possibly make sense when the screen is off. But most probably it'll just cause problems and annoy you. ;-)

1.5.3. userspace: This is if you want to set the frequency manually. Unless you have your brain directly connected with wires to the phone or your are trying something out you should avoid this one as well.

1.5.4. conservative and ondemand: You are probably just skipping through this, huh? ;-) See 1.1. above for the description of conservative and ondemand.

2. How to increase your energy efficiency
Note that I write increase the energy efficiency and not decrease the power usage. You could decrease the power usage easily: Just set up_threashold to 99 and down_threshold to 98. But that would most likely cause your phone to act very weird. And this is not what we're aiming for. We want a phone that works perfectly and just uses less energy. Of course this kind of general tuning is something your phone vendor should have done already. But trust me, I haven't seen a single phone where they actually did. And android mostly comes with Linux defaults, which are tweaked for 100 % performance and don't care much about high energy efficiency.

2.1. Quick&Easy: Interface Tuning
The easiest and first thing you can do is to set the general device settings. Easy power savers are to adjust active interfaces when the display is off:

2.1.1. Mobiledata: 2G only. This could cause problems if you use VoIP software via 3G with the display off. This saves power twice: Firstly 2G takes less power than 3G in standby. Secondly, switching between 2G and 3G can take a lot of power. (The device will constantly try to find and "upgrade" to 3G networks.) Side-effects: It mostly means that incoming phone calls will be more likely to be in slightly lower quality, as 2G uses more lossy audio compression codecs. This could decrease your battery time if you're constantly downloading big files via 3G while the display is off. (Honestly, how would that work?).  (recommendation: 2G only).

2.1.2. Background Sync: disable. This can have various consequences, e.g. Gmail claims to rely on this. But I still get new email and Gtalk noticiations with this off somehow. It's a general setting that other programs might rely on as well. So just see if this works for you. (recommendation: disable)

2.1.3. Wifi: Disable. I don't use this. Because if you use Voip software with your phone it usually detects if your ear is close to the headset and then turns off the display, which makes sense to save energy. Also sooner or later your display may turn off during a call anyway. Then a Voip connection or even streaming radio and other services via Wifi would be disconnected. That's why I prefer to use this setting with other programs. It would be cool if Wifi was disabled automatically after x minutes without usage or when out of range. But that's really something for other tools than CPU tuner. (At least then, the tool should be renamed to something like power tuner). (recommendation: leave unchanged)

2.1.4. Bluetooth: Disable. Side effects: If you use bluetooth headsets etc. they will be disconnected. Hence it only makes sense if you don't really use bluetooth. But then you will probably never have it switched on anyway, so there would be little point in switching it from off to off automatically... Useful if you sometimes use it or play with it and then forget to turn it off again. (recommendation: leave unchanged)

2.1.5. GPS: Disable. This usually saves quite a lot of power. Side effects: When switching back on, it will often take some time to find your location again. (Samsung Galaxy 3, you're annoying me here even with gpsopt...). Also, if you use a navigation software and switch off when the display turns off, this means you will at least lose your precise GPS location and your navigation software will either stop working entirely or start giving very imprecise (and thus often useless) advice: "Go sort of left, but also a bit right, one of the next or previous streets...". Sounds like me giving directions. This only works when the app is installed as a system app (no method does not work universally, also try root explorer and copy the apk to /system/apps).

2.2. Governor Tuning -- Step by Step
This is the most tricky part, but it's worth it: These settings can save you power even if your phone is not in use. If can also increase your phones responsiveness and interactivity while you use it. And it can do both. And it could even decrease power use in both situations. Always start with your vendors default settings. (Assumption: The current/default settings don't cause any mp3 playback gaps, etc. for you; otherwise: Start with 70 up, 40 down; otherwise: start with 40 up; 20 down.)

2.2.1. Make one change at a time: e.g. increase the up threshold by 10 or 20 %. Then listen to music for about 10 minutes with that setting. Check if you run into any problems (see "Signs of Trouble" below). If you notice problems, go back to the setting before, then add a smaller percentage, e.g. 5 %.

2.2.2. Rinse and repeat until you get a fluffy paste. (Once one change works, try another, e.g. first try increasing the up threshold, then try increasing the down threshold.)

2.2.3. Signs of Trouble
The most notable and annoying problem for me is that music playback stutters. (Attention, if you like , noise is probably part of the audio track and not an issue.) This also means that you the other person will hear glitches in skype and other voip softwares. The second, less annoying, likely effect is that the user interfaces will become less responsive, animations will stutter and won't look as pretty etc. These are all things you should watch out for during the governor tuning explained below.

2.3. Putting it all together
Once you find your preferred settings, I recommend creating two profiles for the start: one for screen off and one of screen on. While screen off is a trigger, to use a profile whenever the screen is on just select battery below 100 %. I'd prefer the ondemand scheduler when the screen is on as it's the most responsive in my experience. But as it stands I use only the conservative governor.

3. Causes
In my experience so far, the down threshold is much more likely to cause problems than the up threshold. It seems Linux makes its calculations of when to send new data to the sound card based on the current frequency and doesn't adjust them (soon enough) when the frequency is reduced. (Note to self: File a bug about this to the overflowing android bugzilla, which mostly seems disregarded by developers.) This causes problems especially for the ondemand governor, which is much more prone to create noise during playback in my experience than the conservative one, as it switches back down to the lowest frequency almost immediately.

3.1. Don't rely on Skype as a measure, as skype can often cause problems even if you use the governor to "performance", which effectively disables frequency scaling. I hope they will improve skype, which reportedly works quite well on iPhone, but not on MyPhone. Generally you should check if problems disappear with the performance governor. Because if they don't they're not related to the CPU frequency scaling at all. Hence they are highly unlikely to be related to CPU tuner. In my experience CSipSimple works pretty well, try calling an echo service or answering machine to check how flaky the connection is -- of course you need a stable network (wifi with all stripes!) connection to ensure that it doesn't cause the glitches. You would also notice that they don't disappear with the performance governor then, of course.

4. If all fails
If everything starts to be buggy all out of a sudden, just disable CT and check if it disappears. If you've got no idea what you changed, reset CPU tuner to defaults and repeat more carefully.

5. Feedback
If you've managed to find the perfect settings for your device, please report them in the comments here. Make sure to include your phone device and which firmware you use (as exact as possible please). This may save other people from listening to hours of music to find the perfect settings for their phone. I officially invite to flamewars about what exactly the perfect and absolutely ideal settings for all and any situations, people and devices are. ;-) Once we've found them we can adjust CT to come with them preinstalled and then get them into android as default.

My settings right now are:
Screen on:
conservative, up 50, down 30;
Screen off:
conservative, up 90, down 50.
2g only.

The End.

Tricks used to extend battery life in Android Phones

Share with others tricks used to extend battery life.

Tricks known to me:

1.Reduce your Screen Brightness
Display uses about 5-80% of battery usually. Reducing the brightness helps to increase the battery life a lot. To do so goto Settings->Display->Brightness
- Automatic brightness is good but lead to higher consumption of battery. Close brightness automatic and set brightness low.

2.Disable Wi-Fi, Bluetooth, GPS, NFC
Even though Wi-Fi, GPS and Bluetooth are designed for low-power consumption, they drain the battery. Most of the 2012 android devices have a unique feature known as NFC (Near Field Communion) such as i9070p. This feature enables a sensor field around the handset and is used for sharing. This also drains the battery unnecessarily. So it’s better to turn off the Wi-Fi, Bluetooth and NFCs when it’s not in use.
- Deactivate Wi-Fi when not needed
- If you do not use the Bluetooth function, disable it.
- If you do not use the NFC function, disable it.
- If you do not surf the internet stop any data connection
- As long as you do not use GPS and/or location services, close them.

3. Prefer Wi-Fi rather than GPRS
It may be weird that the GPRS consumes more power when compared to Wi-Fi. For example, Wi-Fi consumes 5% charge; the GPRS connection consumes 15% charge. This may not be seen while viewing websites but in case of watching a video in YouTube or making a call in a VoIP service, it drains the battery at a rapid rate. So it’s better to use Wi-Fi to watch videos or making calls.
.- Wi-Fi network consumes less than 3G connection, it is recommended to use Wi-Fi

4. Avoid Live Wallpaper
The live wallpaper drains the battery to a considerable rate. So it’s better to use static wallpapers rather than the live wallpaper.Also use images which contain black color because the LED screens use less power to display black than displaying white. Doing this helps to increase the battery life up to 10%.
-Use a dark background, save battery. Light backgrounds need more battery.

5.Disable Data traffic
Many applications use data traffic in the background letting this phone to sleep. Some of the apps which use the background data traffic are GMail, Whatsapp, Facebook, Viber, Twitter, LinkedIn, Google Play, etc. These apps checks for the updates and for incoming messages all time. So it’s better to disable the background data traffic.
- Network 2G network consumes less than , it is recommended to use 2G connection
- If you do not surf the internet stop any data connection.

6. Disable Auto-Sync
This option comes under the background data traffic. This feature checks for the mail all the time. Which means you will be able to get the mail in your handset as soon as the mail arrives. But this service uses a considerable amount of battery
- Upload and sync only on Wi-Fi. Or stop sync on all accounts.

7.Do not use more widgets
- The more the widgets, more the RAM, more the battery will be drained.
- Dump the widgets

8.Disable Adobe Flash
Adobe Flash enables to watch videos in websites but it drains the battery a lot. The main reason why adobe discontinued its service from android 4.1 is this battery problem.

9.Turn OFF vibrations
The smartphones makes use of some energy to make a vibration, but when “Vibration on Key press” is enabled, while typing a word the phone produces more number of vibrations. It consumes more battery. So it’s better to disable this feature in the keyboard settings.
- Vibration consume energy. A low intensity vibration or even disable as reduce battery consumption.
- Disable Haptic feedback.

10. Power saving mode
If you use your device constantly throughout the day, you may want to consider using your device’s power saving mode. In fact, many of the tips suggested in this post are implemented in most devices’ power saving mode. For instance, power saving mode usually limits CPU use, reduces screen brightness, deactivates haptic feedback, disables data network when the screen is asleep, and lowers the brightness level of the browser’s background color.

The generally recommended advice is to disable power saving mode when you intend to use your phone’s smartphone features; otherwise, turning power saving off can help you stretch your battery life further. So, for instance, you might want to disable power saving mode if you plan to play games on your phone, or else you could experience lag or jitter.

11. Do not try to overcharge
Normally the smartphone charges up in 1-2 hours. But if you charge it throughout the day, it lowers the life-time of the battery. Check the condition of the battery often to have a good battery life.

12.Reduce screen timeout 
- Screen timeout should be as low as when not using this device to enter sleep mode. (15s)
- Sensitive buttons should be as little heated. (1,5s)

13. Uninstall unnecessary apps
You can never be too sure what's running itself in the background, what with all the multi-tasking, self-uploading, auto-replicating features in today's modern Android apps, so at least minimise the chances of something randomly hoovering up all your battery by constantly trying to connect to some non-existent server, by deleting any unused or old apps. Some apps are resource-intensive — either by nature (as in the case of games) or by developer incompetence or negligence (as in the case of poorly written apps).

14.Never leave applications open 
- Never leave applications open in the background for long time. Set the limit to 1 or 2

15.To root or not
Rooting may have drawbacks but the benefits far outweigh them. One attractive advantage of rooting is that of possibly improving your device’s battery life.

16. Debloating
Rooting itself won’t lengthen your battery life. Rooting merely opens the gates to your device’s restricted partitions and directories. With such restriction gone, you can remove useless apps (e.g., bloatware from carriers or OEMs), especially those that run as background services, wasting away precious battery power.

17.CPU underclocking
With root access on your device, you can also install apps that can improve your system’s performance. A CPU controller app, for instance. Three names instantly spring to mind: SetCPU for Root Users, No-frills CPU Control, and CPU Tuner.

Apps like these essentially allow you to tweak the CPU settings on your device. You can set the CPU frequency to stay at the lowest (and, as a result, use up the least power but sacrifice device performance) or to stretch the CPU to its maximum limits (resulting in better and faster performance, but at the price of heat, quick battery drain, and potential system instability).

Be careful when using such apps. There are risks involved; for example, your device could behave erratically when its CPU clock is set higher than usual.

18. Custom kernels and ROMS
As we have an unlocked bootloader and custom recovery in the process of rooting. Many custom kernels and custom ROMs. Feel free to look around XDA for guides on how to flash custom kernels or custom ROMs to your particular device.

Battery life is one of the biggest issues in the Samsung Galaxy S GT-i9070 Advance. Take your SIM card out, turn off Wi-Fi and never touch it and it'll sit there happily, lasting for a whole week on one charge. But try to use it for anything "smart" and, well, that's where the problems start.

...and keep it cool
Batteries work best in cooler temperatures, with prolonged warm periods gradually lowering their efficiency over time. Putting your phone in a looser pocket might help, or perhaps just gently fanning it while it charges. That might not be the best use of your working day, but at least you'll still be able to get on Twitter on the train home.

Updated :[Use following to get rid of battery issues]

1) Don't use any Memory cleaning apps/Task Killers or battery saving apps.
2) Go to Settings -> Location Services -> Uncheck All (Specially Permission to Google to collect data)
3) Facebook Synch settings to Never (Go Manually and check)

Bingo You are All set !!! Enjoy your Extended Battery Life
