alright, so I've recently started installing custom ROMs (Go Bionix!) and so I've been needing to "recondition" (I put it in quotes because it's not TECHNICALLY reconditioning) and since most of the ROMs increase my battery life, the step involving... you know... draining the battery... takes up to 3-4 hours.
So I got to thinking:
What if we could design an app that is basically a white screen that runs your GPS and pulls data, etc. so that we can kill our batteries faster. What do you guys think?
I was just thinking about that a couple nights age when I was trying to run my battery down. Just stream some Pandora while using the Google Maps Navigation and go for a drive. It worked pretty well for me
You wanna drain your battery fast as hell? Use media hub! That's a power sucker if I've ever seen one. Or, alternatively, get hopped up on energy drinks and play reckless racing for hours on end.
Not sure if I'm correct here, but I thought the best way to condition your battery is to let it drain out as natural and lengthy as possible; as in avoiding heavy data usage or heavy loads. This way it allows the battery stress to be less and successfully make it adaptive to long-time uses.
the thing that works the best imo is recording a video.
Just open up the HD camera, with the brightness all the way up.
It will drain it under 3 hours, and you can just delete the video after the reconditioning!

I think that's for true reconditioning, but with Li-Ion batteries, you don't actually recondition... We're just giving the software some stats to work with

myself i use CPU intensive apps like PSX4DROID and live wallpapers. I also keep the brightness up and screen always on. And...... what i like to do is turn all antenna's like WiFi and GPS on... 5-6 hours, its dead.

+1........
yeah, I get about 2 hours playing Angry Birds
Did this yesterday for a new install of Bionix Fusion.
1. Install free app "Every Trail"
2. Turn blue tooth on.
3. Set screen off for 30 minutes.
4. Put brightness on full
5. Run Pandora. Stream high quality. (turn volume off if you don't want to hear it)
6. Launch Every Trail and start tracking a hike. This causes the GPS to continue locking on your position.
Drained the batter in ~ 3 hours.
I tried Angry Birds and it just wasn't draining fast enough (strange, huh?).
Trapster is another possibility.
Be careful leaving the screen on with full brightness. I have always kept my screens to never timeout and set to full brightness but I have minimal screen burn so I stopped. You can see it well on my phone when using a flashlight type app.
Just a little heads up..

When I leave the screen on, it's usually playing a movie or running a flashlight app.
Okay thats when your wrong, muting the sound wont drain as much battery, it has to be max to drain the juice out faster

yeah, i'll put it between a couple of pillows to muffle it.
Using the app "Battery Monitor Widget" I have determined the following....
My Droid X sleeps at -5 mA while sleeping.
My T-Bolt sleeps at -48 mA or more (usually much more) while sleeping.
Both phones run Gingerbread.
Both phones have the same apps, running.
Why does the T-Bolt draw so much more mA's?
I've turned off the 4G radio and it didn't help.
Any other ideas?
Thanks.
Your T-Bolt is not alone, mine runs in the -40's too. Recently into the high -30's with some undervolting. What rom and kernel are you using? I am on CM7.
GingerBamf Remix with Imoseyon 2.5.3test7 running Extreme and Interactive.
i have very bad standbye life on mine running BAMF froyo versions too. I really want to know what is causing the horrible drain. Nothing really shows up as keeping the phone awake or anything.
I noticed this the other night. I went to sleep around 3:30am (...after tending to crying daughter) at about 50% battery and woke up at 7am to a dead TB. Plugged TB and checked System Panel app and saw my battery drain in about 2 hours with no device usage at that time span but 10% cpu activity while in sleep mode. I have been keeping WiFi on at the house lately which has helped on battery life when connected but have also noticed my TB having a hard time connecting to Wifi when I get back home or waking out of sleep mode. Does Wifi connection cycle in sleep mode if it is having a hard time connecting? Also had two reboots for no reason the last few days as well. I love this TB but these little annoyances are.....well annoying!
Every time I root, I end up going back to stock. To me, it seems to runs smoother and with better battery life than any Rom and kernel mix I've tried.
My phone lasts me all day with some texting, web surfing, playing music, a few calls, some tethering, and some YouTube. When I plug my phone in at night I'm usually down to 40% give or take.
I also use green power to manage my data and WiFi. It works great.
Over night I might loose 1% but thats it.
Just my opinion.

Hey guys what's a good app that you use to track that information for your battery discharge rate?
Nvm lol just reread your post. Thanks.
SETCPU
Im assuming your rooted if so install SETCPU and in Profiles you can turn the voltage all the way down on the "Screen Off" option but make sure you check the ENABLE box and after you wake the phone up if it seems to be a little choppy just go back to SETCPU and check the ENABLE box again which will disable it, works for me
I am running stock Rom with basic tweaks (display, background data) and just uninstalled the task manager I was using and improved my battery life by 30%. I now go almost all day with moderate use with out having to recharge.

Let me just clarify that my battery life is fine. I only lose a few % overnight. I was just confirming to the op that -40's is normal.
Hi All, I have been using the Xda for long time and I am a bit greed and I never register, yep that's right, hate plz come.
But anyway, I have used too many phones that I can't even remember.
Last couples of week, I got rid off my Nexus one and got A Razr, but the disparagement start right with the battery life!
First a few days, I was using only wifi, as one of my number does not has Web pack on it, and I notice a horrible battery performance on the device and I am
Later on, I activied my internet on phone and here comes my theory.
I notice the Wifi is always running for some reason on the background even if I set it as turn of when screen off, when I check the battery usage, it shows almost every second that wifi is on. That should not be right, it should turn it self off when screen off, and it is not doing that.
Second of all, later on, I noticed something like *WIFI* shows under battery usage, and I was thinking what the heck is that, cause there is another "WIFI" still showing, and also something called" .com.motorola.contact. something like that is waking the phone and using the wifi as well.
And there also something like"motorola.home" running and using wifi for ages. Very strange.
OK, then I went out today, yes, I most of the time stay @ home, na I am joking..
I am mostly in a place with WIFI, home, work place, and Uni. All wifi here and there. Today, I took train 3 hrs total out and back from Birmingham to London for those who like stories. it was 1:30 afternoon battery @ 80% then I listen to music for 1 hr and use whatsapp quite a bit(battery hunger app even on iOS)
On the way back I played GTA 3 for one good hour. and it is now 9PM, and 15% left, as later on I tweet a bit, web a bit. which is good, also I took underground so signal is not always there.
After all these my question is for those who had the battery drain, are U in a wifi enviornment quite a bit time and use wifi?
If so, set the wifi sleep policy to Never(this actually will help) and while not using wifi to use heavy data stuff, turn it OFF and see what happen.
Also turn off GPS espically if you have facebook on phone and also the using wirelsess connection for location, turn that off as well.
BTW the GPS on Razr is reallllllly fast on location, it took 5 second to find me from cold boot. Awesome.
And I don't use task killer or smart action, I think using sensor and active these sensor to save battery while they are using a lot juice is not so smart.
BTW: due to I am on and off subway, my iPhone4s dropped a good 15% without any use, it just sitting in my pocket. (as for now, Android is the fun bit, iOS is the backup, as it does hold battery better a bit...lol)
I am on 2.3.6 (651.167.19.XT910.retail.en.EU)
I flash the rom couple of times, it all shows me WIFI is doing some strange thing.
Today still draining and I use a data usage checker and find that moto blur is using a hug a mount of data, WTF!?
I find battery performance vastly better on wifi than 3G. Mine has had atrociously bad battery life recently, so I'm backtracking through stock ROMs to see if I can replicate the setup I got 5+ hours of screen-on time with.
Gotta love those updates. The sooner data works properly in custom ICS ROMs for the XT912, the better.

Sent from my XT910 using XDA App
I've been using SetCPU to create profiles on the ondemand governor and extrapolating from my general usage during commute, news/texts/im, fair amount of screen on time, I'm getting around 10% drain per hour which is fairly nice. With screen off and 3g running leaving the phone to idle, it drops to around 3-4% per hour which is significantly better from what I was getting right out of the box.
Battery test for Motorola RAZR XT910
Yesterday I decided to do a simple test with my new smartphone, a Motorola RAZR, I shall not charge until he get just 15% of battery remaining. So here I will put the results and thoughts about it.
8:00 AM: I woke up and took XT910 off the charger. Wi-fi was turned on;
8:00 - 9:00 AM: I passed one hour using Pulse to read some news, once or twice I shared some news in the Twitter and Facebook, with the Wi-fi on, of course. The Battery got 85%;
9:00 - 10:00 AM: I started to use Whatsapp to chat with a buddy, took at least 45 minutes of intensive use, battery got 70%;
10:00 - 11:00 AM: Cellphone in stand-by, BUT with the wi-fi on, waiting for someone, battery got 60% yet!;
11:00 - 12:00 AM: That one appeared, so I used Whatsapp again for 30 minutes, and battery got 50%;
12:00 AM - 2:00 PM: Two hours with the cells blocked, but still with wireless connection, 40%;
2:00 PM – 4:00 PM: Motorola in stand-by, now with the wi-fi turned off, so, in the first hour, he keep 40% and in the second, he got 30%;
4:00 PM – 5:15 PM: The final test, I passed just one hour playing Ceramic Destroyer without stopping, the battery got 15% and then the phone asked for charging!;
Well, the battery last for 8 hours with wi-fi turned on almost all time, so I think it's was fair, BUT, the battery status is a bit fake, I don't think that the information was correct, but, it works when is a simple test, you know, right?
We all know about the 1,2 Ghz processor, this drains a lot of battery, but the real villain is the connection, wi-fi or 3G, they both spend so much energy of the cel.
My last thought is... always charge your phone when it's possible, even if you don't use in an intensive form, I hope that you'll not have problems because a low-batterys cell phone.
One thing I've found is that when my battery is draining like a tub it's has nothing to do with any data connection. In running apps there's a media process that keeps my phone running at full bore. If I just kill that I get dramatically better battery life. Normally when I don't have to deal with that I can last all day with a quick touch up charge during the middle of the day. This on my xt912.

your right, certain apps can affect battery life so it is ok to kill running task. however just want to make sure other users know that using task killer to constantly kill many apps is not a good idea! most of the apps will prob restart and this cycle will only drain your battery more. whatsapp is a good example, even they state on their homepage you should remove from task killing as battery would drain not just from the constant restart of the app but also the fact that it would continue to regain connection to their server whenever it restarts.
try use a dark colour like black as you know white colour drains much more battery. if your a constant user of google (maybe even if its your homepage too) try use the black google version. save some battery.
i think personally for me 3g uses more battery than wifi. another factor is the network bars that drains battery if low as constantly hanging onto that low connection.
you should try flight mode and see how the battery fairs there so you can get a rough idea.
also come across an app called FreshNetwork which is a signal booster & finder. Android Market - 4.7 out of 5 Star overall rating! (9,152) as i speak, and it does work.. theres been times where ive had 1 bar connections but after using it i get like 3/4bars. so it helps ease the battery drain there as connection is much better.
hope its of some help guys!!
I know theres is some apps that drains battery, one tip is just deactive the auto-sync with your accounts, other thing, I want a batterystatus app, to know better that stuff.
And I will try this connection app, thanks

hey first of all nice site secondly your tips are pretty much on the dot.. just thought of these apps people might find useful
autostarts - helps with disabling apps from auto starting when phone boots up (may be slightly speed up boot?) & also prevent certain app event triggers (maybe an app permission u aint happy with?)
FreshNetwork - helps locate better signals in which in return would improve battery life

first of all thanks for your quick help!
now i did take a pic of the screen and i will do the battery calibration app, but after the instillation of the ROM i did go to the CWR and did wipe battery status but it did noting.
thanks again for your help
Can you give a screen shot like the above but with a little more time on it than 4 minutes? Maybe with a few hours on it. That way we can see a little more info. All that is on that screenshot is the modem initializing and your media scanner.
Also when you wiped Battstat in CWR, that was the same thing as the Battery Calibration app is doing. Just the app is easier in that you don't have to boot into recovery to wipe them.
Do the battery calibration when your phone is charged to 100%. A buddy of mine was having awful battery life, turned out he wiped his battery stats when it was only half charged and then it seemed to charge only half way.
Charged it to 100%, then calibrated and viola.

Perfect. You must have either your GPS or Network Location on all the time. That is what is killing your battery. Do you use Maps/ Navagation a lot? How about apps that track your location like Foursquare/Twitter/G+ or FB (even apps like Angry Birds do this crap). Find the app that is broadcasting and you'll find the leak.
I have the MLB At-Bat app on both my phone and my tablet and on my tablet, I allow it to use my location so I can watch the games. It is a wifi only tablet and I have the wifi policy to cut off when tablet is in stand-by mode. On my phone however, I manually turn it on/off when I want to watch a game, so it never interferes with deepsleep and not broadcasting my location using GPS and battery at the same time. See where I am going with this?
I am betting that you don't get into deepsleep much because of the wakelocks interupting the sequence. Install CPUspy and let it runs for a few hours. After a bit, open it up and I would venture to say that your DS will be minimal.

i don't use at all the GPS or maps or navigation , i canceled all the location services in the settings !
i have no idea how to Find the app that is broadcasting?
i uninstalled a lot of apps after what you wroth me but still no change
i have a felling that all of this is happening because of the devil3 kernel, just after i installed it the battery went low!
Do you have the devil configuration app?
If so, what are your settings?
I run the devil kernel on both of my devices and I average about 28hrs battery life with moderate to heavy use.

Now that is frickin' comedy! On a serious note though, it does get frustrating chasing these things around. After I flash and get everything setup I make a nandroid.. Then when it happens I skip all the trying to find the culprit business and reflash and restore from scratch. I would rather have the hassle than be annoyed lol.
Ever since switching to CM10 I noticed my battery drains fast and takes a long time to charge back up. This morning around 5:30 i was at 60 ish% used it for 10 minutes and left it alone while i was at the gym. I just listened to music on the way home (20 min walk) and i was at 14%. What could be draining my battery so fast?
Install gsam battery monitor or battery stats and it will show you what apps are causing wakelock
Gsam lists two wake locks. One is called media server and the other power amp full version unlocker
What do i do once i actually find the culprits?
You can uninstall them or freeze them in titanium backup
Don't freeze media server I'm pretty sure that's from you listening to music.

Lol yeah I would have mentioned that but it kind of seemed like common sense to me
I was getting bad battery at first, something that caused my problem was a different kernel, also another problem was the way I managed my battery. When I go to the gym and I know I am going to be away from my phone I put it on airplane mode or I turn of the other things like mobile network. Also if you have your screen timeout above a minute that can effect it. Also you have your screen a bunch that will mess you up to when it comes to battery life. So just think about some things that won't really drain your battery and that should help.
