Hello!
When I owned the Raphael I used the Smartlock or S2U2 (tested) to autlock the device!
I was wondering what you use to that purpose!
Thanks
Am actually not using any screen lock software at all. When I want to lock the screen I just put the device to sleep using the power button. This has worked very well for me in the past.
I use Throttlelock. Works nice!

A long press on the hangup key (most right hardware button) also locks the screen.
smartlock has been known to cause some problems in the past..I was using TPC's 6.5 ROM and it had smartlock, and when I tried to use a PIN to unlock the phone, (which was requested after the initial sliding-to-unlock motion) the phone froze up. a softreset fixed it, but after that whenever I tried to disable the PIN, the phone would freeze. I'm using S2U2 v2.02 with my tilt, and when I get the TP2 I'll continue using it. (unless smartlock gets those bugs ironed out.)
ok I know this thread is a couple months old, but my question relates to it.
Regarding Throttle Lock, does it have any issues like S2U2 some users are having such as draining the battery?
Is there any configuration for Smartlock? I've been using S2U2 for so long I forgot about it.

I am noticing a mysterious battery drain since installing S2U2 on my TP2. I'm also noticing that the "Device Usage" in the power information screen is a lot higher than the amount of time I've actually had the device powered on. I am also now looking for a good alternative to S2U2. I don't like Throttle Lock (just personal preference).

I'm using pocketshield now, light and low power consumption + it's cheap ! And one more thing there is an unlock with light wich is great ! and many other features....
after several seconds,pro2 will automatically turn off screen and locked,why you still need a auto-lock??? he can walk,why you buy him a walking cane?

The screen goes off and your device goes into standby, but it's not locked. If your phone rings but you missed the call, your screen will be on and will be susceptible to accidental screen taps.
My personal favorite is DeviceLock. It uses zero resources and utilizes the default locking mechanism.

My friend told me of one which scans your eye to unlock it...
Is he telling me prokies

Thanks, ohyeahar. After spending two days trying to get Touchlock Pro to work reliably I installed this and it just works. It's a simple app but it just may be the best find for my TP2 yet.

I tried pocketshield 3.0, but it drains battery and I don't see anything being locked (though it is locked sometimes)
Uninstalled the program but still my battery drains rapidly, using 450mA all the time

What do you use t show current usage?
Can you explain exactly how you are measuring battery drain with PocketShield. I am MUCH happier with PocketShield than the other locking mechanisms that I have tried (S2U2, Devicelock, etc)
But I have noticed that I have pretty fast battery drain - just didn't associate it with PocketShield. With other locking programs I notice that my screen is often on when I take the device out of my holster so I just assumed that they were allowing for increased battery usage. With PocketShield I don;t notice the screen coming on so much.
Why was this phone introduced by Verizon or Sprint (or even HTC for that matter without this issue being fixed better?
I use Battery Log to see the current used.
After 12 hours just stand by the battery power is less than half the full power! So this phone now is useless!!
I will have to start all over again
there is a setting under settings / wireless and networks / mobile networks that says "enable always on mobile data"
Switching this to off about doubled my battery life and everything still seemed to work okay as far as data goes. All my apps worked including things that check or update periodically in the background - so I'm not sure what this feature does.
The only downside is that the phone would crash periodically in areas with poor reception. It would go back to the sprint boot animation and come up after a minute and the uptime would not be reset.
Imconvinced part of the battery life problem is due ton inefficient use of data, but I'm wondering what can be done about it without sacrificing stability. Ahylne else have a similar experience or willing to try it out or have more information?
Trying this out, seeing what it effects it has on my normally used apps. So far (first 20 minutes of doing it) everything seems to run fine. I would guess this causes the phone to "hibernate" the 3g radio whilst locked.
I started doing this on Hero and continue to do it on the Evo. The biggest issue is that if you are using pandora (or similar app), it causes problems when the phone goes to sleep.
The setting stops your 3g connection when the screen goes to sleep. This prevents the phone from updating email, twitter or whatever else you use. As soon as you turn the screen on, it turns on 3g, downloads your email etc.
I check my phone often enough (for the time or whatever) that I don't mind not getting my email immediately (it downloads when I turn the screen on).
This has saves a ton of battery life. The only time I enable always on mobile network is to listen to pandora. I have done this since day 1 and have had no issues.
I tried this last week and it made a massive difference in battery life. I turned it back on though because I do like my phone to download things while it is idle. I also don't want to get used to the improved battery life just to have to switch it back later.
i dont know if any of you have heard of juice defender what it does the same thing pretty much. with a few exceptions. whereby you can set the program up to allow your phone to take data even if your screen is off at a certain duration of time, then it will go back to sleep.
thats a really simple explanation of what the app does. if anyone of you does decide to use the app let me know i can share my settings more specifically. I have increases my battery life by 87% and i have have 0 problems.
I have this option unchecked and not only has my battery life improved, but I don't notice any performance or stability issues.
Also, my data continues to download in the background as normal (regardless of whether the screen is on or off). I have Facebook and Twitter set to download data every so often and it continues to do so. Even Google Voice will notify me of messages even if the screen is off.
I think what this option does is, when checked, makes the radio work hard to find and keep a data connection (especially in low signal areas). I notice that with the option unchecked, my data connection drops a bit more often than with it on. I don't mind that though seeing that the data connection simply reconnects automatically and almost instantly.
thanks!

Would you all mind doing an experiment for me? Turn this option off (so data is not constantly on) and turn your screen on and put it in your microwave so it loses signal*.
Watch it and see if it crashes. I suspect something about this setting being off is causing the phone to crash when it loses its cell connection momentarily.
*Don't turn on your microwave.
Okay so after more research I'm pretty sure the main instigator of poor battery life is the data connection constantly going wild. According to SystemPanel my phone hangs out doing nothing downloading at 100-200Kbps for large amounts of time. Not sure what it's downloading.
To find out what apps were causing this I used Spare Parts and saw this:
Click for full size
So a process with the PID of "0" is what is using most of the data connection, followed by UID 10011 which is contact/calendar/mail sync. I can click through to 10011 and get details, but if I try to click on PID "0" I get a force close.
There is also another preference under Accounts & Sync for "background data" and "auto-sync." I'm not sure what the difference is between this background data setting and the one in wireless & networks that says "enable always-on mobile data." Anyone have any thoughts on that?
Also interesting is what was happening when I had always on data disabled:
Click for full size
You can see where my phone was crashing but look at my battery life before and after the crash. It looks like it has dipped significantly. Also, the crashes only lasted a minute while the phone rebooted, not nearly as long as what was recorded here - so it's possible something was going on with the battery life before the phone crashed.

I swore Juice Defender only works with GSM and not CDMA.
It even say this when you go to download the app. Although I did just google it an apparently people have it going on the Motorola Droid rooted.
Who with Android experience wants to prove this?

+1 I thought this was the case too. i unchecked the data option. It's been a full day and no reboots
I'm running Juice Defender today and my battery life seems even worse. I'm talking 20-25% drop per hour.
SOMETHING is wrong here.

The option is not meant to enable/disable applications from using the data connection when the screen is off, so applications should be able to continue updating.
What the option is meant to do is to determine whether your phone should maintain data connectivity all the time, even when there are no apps using data. Unchecking the option means that when an app needs data, it must first connect, then make its request. This makes it take a little longer (or maybe a lot longer for 4G which seems to take longer to initialize a connection).
I'm trying to figure out if it's worthwhile to turn off mobile data when the screen is off, and turn data back on when the screen is turned on. It would also be necessary for me to occasionally switch mobile data on even when the screen is off in order to check email. (I'm thinking something like 15 minutes off, 3 minutes on)
Does anybody have any success stories or advice whether I am likely to see any noticeable battery savings by doing this?
I started doing this from when I first got my evo. Just turn off mobile data, you can still get texts and make calls, and then turn it on when you need it. Also turning off background data in settings also adds additional battery, but just enable it when you need the market. I went most of all day with about 80% of my battery still good between it just being off, using the mobile data here and there, and some texting.
Edit: I don't use a tasker, I just use the power widget in my notification, so I can turn on my mobile data on/off with just a tap. And if you're like me you don't know when you actually need it or for how long. So I find it easier and more effective to do it manually.

X2, i use switch pro to toggle mine. Battery drops about 2% per hr while data is of with screen off even when listening to music from my play lists.
I turn off the "always on " mobile data and noticed a big difference. The data turns on and off with the screen.

Over the months I have been an Evo user, I have collected some valuable information that all users should probably know in regards to maximizing battery life. Besides the stuff about 4G and a few specific options, these steps apply to pretty much any other android phone running 2.2, and a lot of them apply to versions below Froyo.
General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users:
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
**IMPORTANT DISCOVERY**When you turn on your 4G radio, then turn it off, it will keep scanning and turning off all by itself.
The problem is apparently exacerbated by a 4G toggle widget, which causes the phone to automatically turn on 4G at boot. This repeating of scanning and disconnecting severely drains battery life, and sadly, no matter what ROM or kernel you use, there is only one way to fix it:
-If you don’t use the toggle widget, then you have to reboot your phone after turning off 4G
-If you do use a toggle widget, then you have to remove the widget from your homescreens, then turn off 4G via settings, then reboot.
**To check to see if this is happening, download alogcat off of the market. Look for the lines saying: I/Wimax ( xxx): <DC> Try to establish a connection to DC server.
E/Wimax ( xxx): <DC CONNECT> IO error: msg=’/xxx.x.x.x:xxxx –
Connection refused’
Over and over again.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
6. Everyone has that issue where the first ten percent go the fastest.
This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is number 7.5.
6.5. Use the trick described in this thread, it works.
My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.
This is the calibration technique recommended by HTC themselves. Check it out!
7. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
8. People posting screenshots of the Battery screen as proof of long lasting battery are giving statistically irrelevant information.
See HERE That screen shows time since last REBOOT, not last charge. This isn't always the case, but a lot of people will post a lot of things about battery life, but look for definitive screenshots and testing results before you break down and cry due to the poster's life and yours.
9. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to menu>settings>about phone>battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 4G Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 4 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 5-10 of screen on
* *Heavy usage – LOTS of video watching and games, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

I am the owner of SuttCo. We developed the Locale Mobile Data Plugin (which can be used by Tasker). It has a condition that can keep tabs on your data use and a setting which can be used to shut off mobile data.
I know Tasker and Locale have screen off/on conditions. I don't have time to run any tests for you (busy working on a new plugin), but if you're willing to do a semi-scientific study and report the findings here... I'll comp you a copy of the plugin. Shoot me a PM.

Not to say that turning off mobile data when you're not using it is a bad idea but I've found during my own personal experience with trying to improve my battery life for daily use that using titanium backup to freeze Google Backup Transport.apk is also a helpful solution. Other things that helped are going into Accounts & Sync and turning off background data because believe it or not, that stuff eats your battery up like a fat kid eating cake...hahahaha...Anyways, another tip would be to hit up Display and turn off Automatic Brightness and play around with the scroll until you come to a setting where you can see because I've found that the Automatic brightness eats up your battery too, not as fast but it does! Another thing that I've done is this and although there are task killers that would do this for you....I've decided to do this myself and after using an app such as Facebook or the brand new CNN app, I've gone into Applications and force close them out just to save battery and all of this nonsense I'm talking about has helped me out alot......NOT TO BRAG but using these little tips of mine, I've gone from 2 and a half hours and I was at 70 percent to 4 hours, 36 minutes and 48 seconds and I'm at 68 percent.....and that's with out turning my phone off, that's talking on the phone, texting, checking my facebook, downloading some apps here and there and just leaving it on in front of me at my desk.

I have setup a few Tasker profiles to do this exactly. I did this instead of JD because the free JD doesn't do exactly what I want it to do, and I don't want to pay for JD when I can emulate it with Tasker.
The only thing I cannot do, that JD can, is keep data on while there is an active connection. With JD, if you turn off the screen while there is an active data transfer, it will wait until the transfer finishes to turn off data.
According to the Tasker website, there is plans to make a state/event "connection data rate" which would make it possible to do this. But that has been in their plans for quite some time. (I actually happened upon this post while searching for a way to check if there is an active data connection with Tasker.)
Also, with the way that Tasker views an "Open program", the program has to be open in the foreground in order to be considered open. This makes it tough to keep data on when a specific program is open, unless you're planning on keeping that program in the foreground all the time. To get around this, I created a profile that leaves data enabled while I have headphones plugged in, since I have headphones plugged in while using all the programs that I want to have constant data with.
EDIT: here are the profiles, and the tasks that go with them (I also included a profile that turns off the wifi antenna after disconnecting from a wifi access point.)

Quite a few smartphones out there support hibernate. HTC is amongst the manufacturers that makes it possible to completely shutdown the phone and write all memory to a file on the nand which is put back in memory when the phone is turned back on. This way it only takes a few seconds to go from off to fully functioning, practically the same thing computers can do for years. Now I wonder if this could be done with the Defy (and possibly any other Android phone for that matter). I don't know how HTC does it but I guess it's pure software as in not an integrated Android feature. And if they can do it I'm sure some of the XDA guys can do it. Or is that wishful thinking??
Well if you want to save battery, then there are certain task killers which actually closes all the tasks which are not in use but running (excluding ignore list) and this way whenever the screen is turned off, it closes those tasks, that improves the battery. If that is what you meant?
I found this on google:
http://www.androidzoom.com/android_applications/tools/hibernate_ctp.html
No what I mean is in the event you have to shut down the phone entirely that all content in the RAM gets written to nand (or maybe sd). This way when it boots again it simply restores its RAM within seconds, effectively cutting boot time to only a few seconds instead of 40. Compare this with Windows' hibernate function for the pc.
Turns out HTC calls it Fast Boot. It's not a real hibernation function because if you put the phone to sleep with it and remove/replace the battery it would perform a normal cold boot. So it's more of a very low power sleep mode, guess more like a computer's S3 sleepstate where only the RAM stays powered while all the rest (cpu, chipset, video, audio etc) is turned off.
Sounds like a very interesting option, very curious if this would be possible on a defy.
This would be a nice feature.

Or turn it all the way off and save even more power.
There are also plenty of 'smarter' ways to safe power, such as scheduling the handset to automatically disabling 3G overnight etc, which don't even require you to switch the handset off.
Airplane mode still leaves the cpu switched on. The purpose of that mode is to be still able to use the device without a working connection.
Say you are away from home and didn't bring the charger. Now the battery is almost dead. Then a very low power sleep mode would come in handy because it boots in only a few seconds and after a few more seconds you can turn it 'off' again. Fast and snappy, hardly using any power. And this is XDA so another extremely valid reason to have it is simply because we can. For pc's it's everyday technology so why not make it available on our pocket sized super computers?
I always disable hibernate in my PC.
Actually me too but I do use the sleep mode quite often with my laptop. Works great when you move your laptop a lot to other places but don't want long boot times. It could actually survive days in this mode on a full battery.
Hello guys,
For years (since I bought my first Android phone) I've asked myself: "Why the heck these smartphones can not turn on at a given time, as did my old java / symbian phones?!?!?!. Man, its a must-have feature, for those like me, that use the phone's alarm clock to wake up every working day! With all my old non-android phones, I could simply turn the phone off and let it "sleep" over night, saving A LOT OF BATTERY JUICE!
But unfortunately, when I bought my first android phone (in 2009), I simply "learned" that, tecnically, it is "impossible" to make it fire an alarm when it is powered off. I simply took it as an undisputed truth, and resigned myself from trying to find a workaround, because the apps on Play Store that claim "auto power on/off" don't REALLY do it, they just make the phone a little bit more battery-friendly over night by disabling phone calls, wifi, bluetooth, etc., but they DONT POWER THE PHONE OFF. Yeah, its better than nothing, but it is NOT like it was on symbian phones.
Then, I bought my Lenovo Vibe K5, and... SURPRISE!!! In the stock rom's Settings pannel, there is a new option that let the user configure the phone to auto power on/off at a given date/time!!!! Then, I asked myself "why on eart this feature is not available on other Android Phones?!?!?!?!
- Edit: I know that, tecnically, to be able to turn a phone on automatically, the phone can not be completely off (the battery needs to be in place and with some juice available - duhhh!!!). I know that it needs a triggerer (in other words, something like a computer's bios), but the fact is that my K5 Stock Rom really starts the Android system from boot. I wrote this because there are a lot of "experts" out there who uses to blame those who ask for this feature, saying that it is an impossible thing to accomplish, and bla-bla-bla...
Back to subject: Fact is that, because of this feature, I became even more fond of my K5: it powers off at night, saves battery, powers back on at morning, and fires the alarm. Sweeeet!
But unfortunately, after installing the AOSP Extended Rom, I noticed that this feature is gone. To be fair, it's a rock-solid rom, that I recommend to every K5 Plus user - but I really miss the feature (hey, rom developers, what about it?)
Before I decide if I do or do not reverse to stock rom, I ask you guys:
Why on Earth isn't the auto-power on/off feature available on all Android Phones?!?!?!?!
Edit 2: Sorry for my bad English.
Edit 3: To moderators: Sorry for posting in this category. Feel free to change this thread to the "Qhestions & Answers" thread.
Well, that feature isn't exactly needed anymore. Android's Doze features make sure the phone doesn't lose a lot of battery when left unused for long periods of time. If you lose more than ~5% of battery juice overnight (when it's already below 90%) on Marshmallow or Nougat, that's something to worry about.
Of course, you can turn Airplane Mode on every night and turn it off when you wake up, or write a script to do it for you, if you want to get the best out of your battery life. The "auto power on/off" feature existed in the stock ROM because of popular demand, and I doubt it's that important a feature to people using other phones and ROMs.

Android's since Marshmallow takes care of idling sleep. (see Doze mode: https://www.bignerdranch.com/blog/diving-into-doze-mode-for-developers/)
If you have high drain during idle, you probably have an issue with wakelocks preventing your phone to sleep (i.e. enter Doze).
Naptime's great if you want to make sure the go on Doze early, and to make sure it's reapplied after waking up.
