I see lots of posts around the Interwebs complaining about battery life on smartphones (specifically Android ones, since I don't hang out on sites that are aligned with evil Apple), so I decided to consolidate my knowledge for people with Slide's to improve their battery life.
DISPLAY
This uses about 80% of the power according to battery use on auto-brightness. On a bright day I can read the screen at about 1/5 position on the brightness bar which cuts down heavily on the battery use.
There's not much else we can do to cut down on screen power usage, so moving on.
CPU
This one requires SetCPU, I strongly urge you to buy it from the Market (it's just a few bucks IIRC) and supports the AWESOME dev. If you're cheap just go download it from that link.
Once you have it you'll want to set up profiles! So click profiles, check the box next to the Sleep profile and choose 480,000/480,000 with ondemand scaler! I have no idea if it actually changes anything but the placebo effect is nice. Next back out of that and set the CPU governor to performance. What this does is clock the CPU to 600mhz constantly instead of scaling between 480mhz and 600mhz as the additional power is needed. It cuts down on choppiness while barely increasing the amount of battery required (in my experience the Slide tends to jump up to 600mhz when I'm not doing anything anyway).
Sync
Turn auto-sync off or set the sync intervals to the highest number possible (once a day I believe). It takes power and most of the time doesn't download anything important. If you really need some data just go and hit Sync Now and, well, it syncs.
Autostarts
There is this nifty little paid application in the market (costs like $1.25 or something) that you absolutely need: Autostarts
Basically applications launch when triggers are triggered, alot of these are pointless and just take up RAM and power.
These are what I have disabled:
After Startup
{Any 3rd party apps that aren't widgets}
Calendar Storage
Download Manager
Voice Dialer (unless you, yaknow, use it)
Maps
Mail
Calendar
HTC Media Uploader
My Account (unless you like the power alerts that take up power!)
Connectivity Changed
Download Manager
My Uploads
HTC Media Uploader
Genius Button
Media Mounted
My Uploads
Application Installed
Voice Dialer (wtf?)
Pico TTS (sem-wtf?)
Application Removed
Voice Dialer
Application Replaced
Maps (lolwut?)
Autokiller
There's an app called Autokiller, it changes the internal task killer's settings as to when to tell an app to shutdown (at stock settings this is almost never).
I use the moderate preset, but you may want to increase it if you never want to have to manually kill a task. Note that this method tells apps to cleanly shut down so data is saved (such as the page you are on in the Browser)
Additional Settings
In Mobile Networks set to GSM only (no 3G)
Turn GPS and WiFi off when not in use
Turn always on data off
Use a silent or vibrate alert method instead of sound alerts
Turn off your screen whenever you can
If you flashed ENG-BUILD flash the updated RADIO!!!!!!!
Protips
Do several battery cycles every 6 weeks (Charge to 100%, discharge to 0%, charge 2 hours past green LED while phone is off)
Espresso is heavy duty stuff, use a non-sense ROM for additional speed
Charging via USB takes significantly longer than charging via AV
Live Wallpapers will use lots of battery
Use wallpapers formatted at 480x320
Limit the amount of widgets you have to around 5 (unless they are from the same app, like Beautiful Widgets) they constantly refresh and do their thing in the background
I learned most of this thanks to enatefox's guide which I modified to suit the Slide, a coffee fueled mind, and general observations. If you have anything to contribute please let me know and I'll add it!
check general, few threads there on this .. it seems the development section is the hot spot around here..
an APN widget will do wonders, or even juicedefender.
i disable APN until I need it. screen is about 30% always. after everything i do i lock the screen.
on a normal days use (1-2hr phone calls, 30-50min of browsing the net, a ton of text messaging, and streaming slingbox) I'll have about 60% battery by 10pm.
great guide. thank you.
does autostart continually kill those processes? I ask because that long list of bloatware you listed is what is irritating me on my slide and even when I force kill them all they restart themselves every 5 minutes. I have taskilller set to kill them and they come back like the herp constantly.

Autostarts does not 'kill' processes, it disables them from running when certain triggers are triggered.
For example if SpywareApplicationOVER9000 runs everytime an application is installed, and you disable it in Autostarts, then it will not run when an application is uninstalled

Can you write up a quick how to for Juicedefender?
Anyone here using it? what is this app for? is it worth buying? does it give u battery life? im really interested but i cant find no videos on it on youtube. please share your thoughts.
It is worth every penny. The best app for android IMO. It is not very easy to master it, but even the basic stuff has made a vast difference too the behavior of my phone.
For example, I have extended my battery life to 38 hours simply by having it automatically go into airplane mode between midnight and 6am.
It will turn off wifi, back screen brightness down, change screen timeout to 10 seconds and give me a notification popup and sound when my battery drops below 15%.
It will turn on gps when Wavesecure is activated, something Wavesecure can't do by itself.
It will turn my ringer off when I get within 200m of the two cinemas I go to.
It turns wifi on when I get home, and off when I leave. Same for work.
It loads my music app when I plug my headphones in.
Tasker can make widgets! I have one set up to (with one press from my home screen) turn up screen brightness, turn on gps, turn up speaker volume to max, wait 2 seconds, then launch google navigation. It will then turn everything back when I exit out of navigation.
It will, on weekdays, text my girlfriend at a certain part of my journey home after work. That way my dinner is ready when I get home!!!
I would say try out the free 1 week trial. There is even a wiki and web site with extensive instructions and examples uploaded by other users. You can also import profiles as well as create your own. The really handy ones I have exported to my sd card, and e-mailed them to a friend when he bought Tasker. Not sure I helped him though as there is a steep learning curve for this app, and it is worth being patient with it to learn its ways for yourself.
I think it is worth much much more than the asking price.

wow sounds sooo nice . i already bought full version yesterday but havnt even opened the app once . well i did open it once it seems hard to understand lol . so for all this task does the gps need to be on? or not? and can u turn off 3g?
You can turn off APN, but don't think that works well in the UK. Sorry, my knowledge of 3g is limited.
Basically, you can have tasker turn on and off nearly any feature of your phone that your want. There are two sides to tasker. The "Profile" and the "Task".
I have found it is best to first set up the "task". Say you want to save battery power at night. Select the task button and select "new". Call it "power save" or something. Select the + symbol and select "Net". In this menu, pick "Airplane mode" and select to ' on'. Then hit ok, then save.
Now to create the 'Profile' where you define the contexts that will activate the "power save" task you just created.
Select 'new' then select the 'time' context. Enter the time you would like to have your phone go into airplane mode. After hitting 'ok' it will take you to the profile page where you set up what now happens between the times you just specified. From the drop-down at the to of the page, select the "power save" task you created earlier. Hit 'ok'.
Done. Your Tasker will now shut off all your radios between the times you entered.

Worth every penny. I use it to:
- turn on GPS for programs that need it (turns back of when editing the program)
- turn notifications off when starting desk clock
- change volume when connecting head phones
There are endless possibilities, try it and then buy it.
i've bought it for little things but want it to be able to handle 3g data which it doesn't
i,e turn on wifi, if no conn after 10 secs, turn on 3g, auto sync for a min, then turn data off.
works fine and dandy with wifi, but not 3g.

You need APNDroid to disable 3G.
tasker really is worth every penny!
Wort every cent. Must have
I used to check periodically (every 3 minut) if my car Bluetooth near. If yes connect and and hold on the connection. If disconnect wait 15 minutes and seek again... save really battery... fantastic...

Wow sounds like you have a good understanding and has some good stuff. I don't know if you can, but I posted a page where maybe people can leave profiles for those of us who are a bit more chronologically challenged.
This is the greatest
I use tasker for everything. I am very forgetful so I have it pop up astrid tasks when I leave the house or work. The quiet mode works well for work and there is even a way to auto check in to foursquare.
Worth every penny, it makes your phone 10 times better and is a must have app.
I have profiles that do the following:
-During work hours and within range of the office set Vibrate, turn off wi-fi.
-When within range of home turn on Wi-Fi
-If at home after certain time in evening go silent
-When leaving car (detected by bluetooth connection to stereo), store time and location. Have icon on desktop to retrieve info and show on map to find car.
-When on call (by checking diary) if a colleague calls always ring regardless of silent.
-Say caller/texter name
-Send magic packet to wifes phone to report location and show on map (handy when shopping)
Plus many other scripts....
I find that this program has a pretty high learning curve...
Is there a wiki I can read up or a way to import other people's profiles?

Using "Cell Near" instead of GPS
I was using Tasker to turn WIFI on and off based on GPS locations. However, I found an alternate method that does not use GPS calls (and waste battery use). Instead, I am now using "Cell Near" to find the cell tower near home and turn WIFI off when I am not within distance of it.
I have posting walkthroughs of all of the most useful profiles I have collected. Check it out at http://dbilliter.blogspot.com
Tasker rules my phone... With all the taks i made.... Love the app!!!
You can do almost everything if you know how to use it... Little variable programming and your phone will get his own life haha...
GREAT APP

If you're interested I've put together this thread http://forum.xda-developers.com/showthread.php?t=1018245 on how to use the CPU Profiles - I hope it's good enough to replace SetCPU!?
Let me know what you think.
problem with deleting profiles
i am also new to tasker. made a simple sms schedular, which worked fine, but when i deleted all the profiles, contexts and tasks...somehow sms is still going on scheduled time... tried to clear data, force stop it, but still sending sms.
any suggestion.
thanks
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.
Please don't start posting "Oh what, you want a FUC%ing cookie now" and all of this....all I intend to do is help someone by sharing my story....that is all! I got to get my butt to working again...hahahahaha

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.)

I would notice overnight that my battery would be completely horizontal (no drop) and thought it was the combination of SETCPU and JuiceDefender (night profile + screen off drop mhz).
But, after unisntalling them, I noticed the same "flat line" at night and also achieved over 30 hours of battery life.
My question is... do these apps really make a difference on our phones?
Or, are the phones advanced enough to handle everything just fine?
your thoughts are appreciated.
I agree... I got about 27 hours of life out of my battery without set cpu or JD (i've never liked JD anyway because its like putting my kid on riddlin)

Which version of JD are you using? If you have the Plus or Ultimate version, you can probably still gain some benefit, but you need to learn how to custom configure the settings so that you use the ones that are still relevant. For example:
Where Not Helpful: JD will turn off your GPS if an application isn't using it, but most of today's phones will do that anyway.
Where Helpful:: In advanced settings, you can provide a 'night schedule', wherein during this time, JD will disable mobile data, and thus polling, so your phone will not go out and check for mail, FB messages, Tweets, etc. Otherwise, mobile data is off unless you 'wake' the screen for some reason. Or another feature that 'trains' your wi-fi to only activate when you are at home or a 'recognized' wi-fi spot. These are a couple examples, there are others.
Where it MAY be Helpful: JD can disable mobile data for a custom # of minutes (10/15/30/60) and prevent background sync during those periods. It will awake, allow the sync, then turn mobile data off. Now some apps may only sync in these intervals anyway, but unless they're all syncing at the same time, you could have lots of 'up' time. Some of this may not 'wake' your phone from Deep Sleep, but depending on how sloppy the code is, it might.
Hope this helps.

I think really depends on the ROM you are running. ViperROM has a script that changes the CPU speed and governer on the fly. So no need for SetCPU there. I'd say Juice Defender can still come in handy with turning data off when you aren't using it.
My 2 cents. Your results may vary.

I use ultimate. I did run a night schedule, but that kind of points back to my original observation... I'd have night setup from 11pm - 7am and see a horizontal line for battery during this time (wow JD is really working)... BUT, with it uninstalled, during the same period of time 11pm - 7am my battery was also horizontal line... So did it really do anything? I'm on wifi at my house so when I'm sleeping the phone is wifi and not constantly pinging the mobile network (does that make a diff. being on wifi)?
I also did like the wifi only when home setting.
With ViperRom, I probably don't need set CPU anymore... Maybe i'll throw JD back on.
One question.. were you running the beta JD? I noticed the beta would always throw errors in the log stating i needed to uninstall, reboot, reinstall (I never did) anyone else have that happen?
These numbers sound like you have the radio off and don't turn your display on. Pretty amazing numbers otherwise. Would love to know the rom + kernal you're using
edit: I see the post above you mention viperrom. Typically if you have data turned off and display off any device will last days. My OG evo lasts for around 48 hours just sitting there. Still really impressive if you're using your phone within that 30 hours

I've never tried the beta; I started with standard, upgraded to Premium, then eventually upgraded to Ultimate (I use the 'Customize' setting, but rarely the 'Advanced' config).
I hear ya on the night-time wi-fi thing. But with this particular phone (and before I rooted and changed ROM/Kernel), on some nights I would be connected to wi-fi and get ZERO CPU sleep time, other nights it would sleep - I have no idea why. It is conceivable that if the only polling your doing is e.g., Gmail, that either it doesn't happen at night, or it happens in such a way as to not knock the phone out of sleep (it IS Google's OS after all).
On a related note, I'm using K-9 mail (my primary mail is Yahoo); it throws wake-locks all the time (set to poll every 15 minutes), but they don't seem to impact battery life or take the device out of deep sleep which is why I suggested that case above.
One other item I like about JD is the ability to permission each and every app for wireless/network access; obviously mail, calendar, phone, etc. need it, but some apps simply don't, and I've been surprised when I set it to 'notify' and some random game pops up seeking network access. Looking for an update? who knows, but I lock 'em down anyway.

I do not turn off data/radio (no airplane mode).
I'm running ViperRom 2.2 with the latest loskernal experimental.
My display was on for roughly 2 hours (again, just used it as i happened to during the course of the day) and data was on.

Interesting thing is with the latest JD build it has the bluetooth settings, so i can leave my headset paired, but the phone disconnects while not on a call and then when i get a call, it turns on... kinda cool.
In regards to the permissions... do i need to give the email applications permission for enable/screen off? (so that I'll still get the notifs?) or just enable (as in when screen on).
thanks,
RR
I've lately got into developing mobile apps and even though i've promoted this as beta, people seem to be using it, but nobody's reporting back! - same goes for all of my apps, i don't get it...
Anyway, i need real feedback and I was wondering if any folks here with a rooted android could help test this app out, it was made on Kitkat, so while yes, it works fine for me, it may not for you... I've had one feedback comment saying that his modem data was not switching off on lollipop, so i added support for that now allowing him or her to use the app as intended, but after replying via the playstore, nothing was heard of him since... almost suspicious lol

Find it on Android's Playstore... Craig's Battery Saver ROOT

How it works..... read on
How it works, if you're interested!
2 things use up battery power
1. apps that are CPU intensive, eg constantly repeating to connect (this would only happen under malware, as most apps would never do this, it would see the socket it closed/dead and stop and wait until user input, malware would constantly reconnect.. but 99/100 apps will just stop and then do nothing meaning all genuine apps should 'idle' not really using up cpu time....
2. Hardware services, bluetooth, mobile data, wifi, gps, these services are all hardware, so your cpu will switch on each of these services and each one has a significant drain on your battery, go bed at 11pm, by 9am it may have drained 30 - 40% or more... with this app, it will have drained under 1 - 3% depending on your battery (tablets for example should run for days with this app if rooted)
So this app does 2, it first remembers which hardware was on before the screen goes off, so no confusing switch wifi on when wifi's already on (as i've seen on other apps?!) reason why i wrote this because all the other apps i came across sucked really, almost but not quite etc etc..
With this tool, if you're a light user you could quite easily see 60% battery improvement! the bonus side affect of this app is also interesting, for 1, it charges quicker! if you accidentally fall asleep, it will conserve as much power as possible, obviously sms,telephone/mobile network is still running in the background so you can't completely stop a device from draining...
the other bonus side affect was, it kills dead all facebook notifications, twitter, well it would as it disables wifi, modem. 3g, bt when the screen goes off! :good:
1 more feature, if you drop your phone? then what?... take where's my droid, i sms it asking for location... it replies "GPS OFF" and "modem off" simple, send the text message to your phone with "on" without the " " around on, and the app will disable itself so it does not switch off the services and then at the same time it enables Wifi, Modem Data, Gps, Bt pretty useful huh... then on where's my droid, you'll get GPS combined with AGPS data from mobile data giving you pin point accuracy, as soon as you get the data of where it is... type in
off (to turn this feature off) or
on (to turn on all your services)
It also disables itself taking calls...
It has a smart check feature too, let's say after you switch the screen on and for some reason wifi failed to switch on ? after 3 seconds it will then check again to see if wifi is indeed on... if it's not on, it attempts to switch it on again...
Feedback is greatly appreciated so i can support a larger range of devices.... thank you for reading! (Suggestions, welcome!)
So basically what your device is and what's not working (along with build version, lollipop/kitkat etc) and i'll see if i can find a way to add it in to support your droid! - one more thing, i've been releasing updates like a crazy woman collecting cats lately and even though it does all this it's only supporting "Extreme power saving option" come tuesday i hope to have that sorted out so that every few minutes it can wake up to check for twitter/facebook messages for all of those who hate the sound of a phone being blissful quiet
if you're rooted and it does not look like that in the video [top of screen] (not the interface, but the services, i've already updated the UI)
anyway, help me to make it better for you...
One more thing, there are no push notifications, no popup adds, no huge banners, all my apps have one tiny advert to help support the countless hours of programming i'm putting into this apps, with each upgrade i aim to make them more stable and more usable, and i really need peoples help and support even if that is criticism - it's "beta" but i'm almost ready to bring it out after i add the wake up services....
Nobody has a rooted device?
Unlike other battery savers... it really does work
