Gives you the best Battery life? I just installed CM7 and it seems like my battery dies faster than normal...
You're just going to have to test them all... you could flash one that can be over/under clocked and under volted like The Escapists kernel. But before you do that have you cleared your battery stats? Flashed the Latest nightly? The most recent nightly actually has pretty decent battery life.

First, make sure the do a battery recalibration after you flash. If you don't know how, following the following steps (thanks to Team Phoenix for originally writing this up and (hopefully) allowing me to repost):
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
3a. Repeat step 1, 2, 3
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
7. Use ADB or a Terminal Emulator to run the following command:
Code:
su
rm /data/system/batterystats.bin
7a. Reboot into clock work Recovery, and choose advanced CWM features and select wipe battery stats
After that, before you decide a ROM or kernel is a problem with battery performance, look first at the apps you are running. It seems that most of the times I read where people have bad battery life, it turns out there is an app that is either running in the background or doing something that kills the battery. Like having a weather app that updates weather every 5 minutes based on your current location. That means GPS fires up every 5 minutes for who knows how long.
I have been a flash addict and have used to flash multiple times during the day and was horrified by battery life on any of the ROMs. Once I figured out how to do a battery recalibration, I came to realize the battery worked well and then started looking at apps.

None of this can actually be applied to CM7 except for deleting the battery stats and checking the apps because of the way the kernel works if you plug in the charger the phone will begin to boot up... so just go ahead and get on the latest nightly, delete the battery stats and if you still don't like the battery life flash a new kernel delete the battery stats again and go from there. It will also take several days for the new battery stats to "settle in". Keep in mind CM7 is still a work in progress so it still doesn't have the battery life it will when finished.
Thanks for the advice guys I really couldnt tell why my battery died so fast cause I fwlt like it was going faster than normal...

Since i hit the option of wipe battery data, im having some issues with my battery it drains really fast. i tried those steps but i dont know if i did it rite?
Battery recalibration
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; power off and let it keep charging until the light is green.
2. Boot to recovery mode and go to console (or adb shell) and type:
mount -a
rm /data/system/batterystats.bin
1. Reboot the phone and use it normally, but don't charge until it shuts off.
2. Recharge the phone completely and then use as you normally would.
Note: Newer Amon_Ra recoveries have an option to delete the battery stats, do this in place of the console commands above, but charge/discharge as stated. ***************
Thats what i did:
Charge the phone when its off, fully charge, unplugged the phone and wipe battery stats, use the phone and let it get off by itself, recharged the phone and still the same issue,
i did something wrong?
Are you sure it's because of battery stats? One thing that drains the battery on my phone really fast is if I enable keeping home app in the memory on CM ROM (done via Spare Parts).

well i did what u say and my phone still turning off even when the battery its half way,
Which is the best style to calibrate my battery? I't only lasts for 10h.
10 hrs is pretty good
i only get 4 hours under heavy use
I forget which thread it was but it said to completely discharge until the phone switches off (ignore please plug in prompts) and completely charge it back up 5 times. It worked wonders on mine
4 hours? pah, i can kill mine in under an hour lol
seriously though, it all depends on usage and how much you have running on the phone (big widgets and social feeds for instance), screen brightness also has a big impact.
On average i get a day out of mine but my mums boyfriend, with the same phone uses it far less and has had 3 days from his on one charge
Ok i'll try your method. Thanks guys!
I have mine going down to 79% within half a day,only standby and frequent switching on of the screen, is it normal? Thanks!

Just wanted to share that I got an improvement
after recalibrating the batery,
Basically just charge full with phone on
then turn off, charge, turn on, turn off, charge.
I advice this for those who have flashed the firmware..

Click to collapse
So which one of these two methods is the right way to do it?
EDIT: And how good is this guide?
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6. Boot into recovery and reset battery stats (or, go to console and type “su” enter, followed by “rm /data/system/batterystats.bin”)
7. Run the device’s battery down until it turns itself off.
8. Charge to full while off.
9. Restart and use as normal.

IMHO, the battery stat is just pure witch doctor style..
Id recommend you use the phone till it drops down the 2% then power it off and charge it while its off.. that way it MAY take upto 4-5hrs charging when it says its full remove the battery for 1-2mins then install it again and charge it while unplugged its gonna charge for ~5mins and when its full disconnect the charger and power on the phone.. you just need to do this once ( on my experience ) and charge as often as possible since its not a good idea to keep draining lithium batteries

While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:

it looks like that nothing really happens, but it does.
Reboote the phone. Important!

There's another method^^
I really don't know which one of the 4 battery calibration methods that I've mentioned above I should use?
I've read from many sources to not worry about frequent discharging/charging of your battery. The lithium-ion batteries we have in our phone will degrade based on cycles (when a certain number of charge cycles have been reached). As for overcharging, the phone is smart enough to stop charging once the battery is at 100%. The battery will slowly discharge, and once it hits a certain point between 93-98% it will start charging again.
As for which method works the best...I'm struggling with the same issue. Personally I've tried almost every method other than the reset battery stat (which I plan to do as a last resort).
I have found that the battery gets better after a few weeks of use. The full discharging/charging does help marginally. The turning on and off method of charging also helps marginally. The biggest culprit is usually background apps preventing your phone from properly sleeping or activating your data when your phone is locked. I was using juice defender and my battery still drained crazy. I JUST changed my juice defender to turn on data for 2 mins every 30 mins (as opposed to 1 every 15) and it seems to have made my battery better. Before I did this, my phone drained 40% in 6-7 hours (while i was sleeping). Right now... my phone has been active for 5h48min and is at 72% (a bit of texting, a bit of 3g, and wifi). Here's hoping it'll get better.
This thread helped a lot
My phone drained 70% of battery from 5am till 12pm (while I was asleep). When I saw the battery usage stats it said that Android OS draind 68% of the battery. I flashed the phone on sunday. I should do a calibration then, right?
I'm going to try this method:

It seems to me, alot of people do this with their samsung devices, and htc devices...
Do any of you milestone owners do this?
If not... heres how:
Either in TERMINAL or ADB enter:
rm data/system/batterystats.bin
Click to expand...
Click to collapse
1. turn off the phone, plug it in, preferably overnight.
2. boot the phone up while still pluged in.
3. delete the batterystats.bin file ether through adb or terminal
4. drain the battery fully, untill it powers down.
5. wait a min or two and reboot it to completely drain it.
Congrats... your phone now knows correct voltage values for 100% and dead.
Remember: Flashing a new build/rom erases the battery stats, and automatically rebuilds them based on voltages it sees.
NOTE: you need to recondition after each flash to get max battery life.
trying to do what u said))
u forgot to "unplug power" to drain the battery ^_^
Does it really help? I've tried something similar, but without noticeable result! =(
seems to be working much better now. Some say they dont notice anything, but i pulled my phone off the charger around 11am today & normally im down to around 75% by this time, (6pm) but im still at 90!!!!!
So yeah im going to say that this works pretty well!
I don't know if this is any help, but during the charging stage while the phone is off, if you take the battery out, the stone will go from 100%, and then reboot, but go back into the same charging screen with a big ? in the battery.
Place the battery back in, and it will go to 60%, and continue charging until the battery reaches its top voltage, around 4150-4200mV depending on condition on the battery. I noticed that when it would jump from 100%, to 90% in only a few minutes of use, that the battery had only been charged to about 3900mV, yet it still displayed 100% and would not charge further

Touché sir!
Just did that.. since it was off/charging before i head out to work, then did the battery pull & got the ?? then down to 60%
weird... there has to be some way to FULLY obtain 100% charge, every time... ya know?
Yeah it seems to work!!!!!!! GREAT!!!
EDIT: everytime that the battery has fully charged, when I take it out and then in again, it always displays 60% and starts charging again..
figured it out...
1. do the battery pull trick
2. get to 100%, then boot-up
3. while still plugged in, sweep the battery stats
4. restart (disconnect while rebooting)
5. FULLY drain, restart to ENSURE dead-battery
6.plug it back in charge to 100%
once charged, unplug & enjoy!

You'll find that it will jump up from 60% to 100% in a few moments when the battery has reached its max mV and wont charge any longer if you keep doing this little trick.
This clearly shows that the android operating system has a flawed battery monitoring system. Although the battery pull trick works on the milestone, other devices report this same problem, and have different little 'tricks' to get the battery to charge fully.
yeah i wish we had an app like the One-Click-Lag-Fix that would do that for us, instead of us having to manually do it.
I dumped my whole system cache, plus swept the battery after gaining 100% charge. It works much better now. I use CacheCleaner Legacy to clear my system & dump the file using Terminal.
Removing the battery and reinsert again works, but just once!
Next time, when it fully charges, you have to do the trick again, because it charges just until 60%, even erasing batterystat.bin
Isn't possible to hack batterystat.bin in order to make it charge completely?
The display seems to consistently use too much power.
After six hours unplugged today:
The battery usage screen shows
Display - 98%
Cell Standby - 2%
That's kind of ridiculous since the battery history menu shows the screen having been on for only 1hr 43 minutes
As said in the title the remaining battery is currently 34% after 6 hours in from 100%
Any advice? I've had terrible luck with the SGS's so far (1 soft key sticking, 1 fried internal SD card). None of them were spectacular on battery life but this is by far the worst unit.
Battery drain you must have loads of stuff turned on .
jje
Do you have android 2.2?
it shows all the not standby usage as display usage. a bug in 2.2 i think.
So the usage you see is display + the programs you are using.
Yeah it is 2.2, I didn't realize the usage stats were bugged. As for loads of programs, I don't run that many but I've only been using the Level 2 Clear Memory function in the RAM manager to end programs. Too much debate around task killers for me.
OS Monitor shows only a few non-stock programs running right now, are any of them battery drains?:

Try this it worked for mine
1. Use your phone until the phone switches itself off (battery empty)
2. Switch on once more to make sure battery really is 0% (it will then immediately switch off once more)
3. Now, keep switched off (!), plug in charger & leave in charging until 100%
4. When battery is full, switch the phone on, unplug & check if the batter immediately drops 1 or 2 %
5. If battery immediately drops, plug in charger once more (while running phone) & let it charge completely
6. Once charging to 100% is done, keep charger plugged in & Reboot into Recovery Mode
7. in Recovery Mode go to: advanced --> Wipe Battery Stats --> Yes-Wipe Battery Stats
8. When done: Go To --> reboot system now
9. Once system has rebooted, unplug charger
************************************************** *********
After 3-4 full charge/full drain -cycles, do the following:
1. Charge the battery up to fullest.
2. Keep it plugged in to charger, and reboot to recovery.
3. On the recovery, go advanced, wipe battery stats, scroll on to yes BUT Don't wipe them yet. When you're ready, quickly remove the battery cable and push to wipe the battery stats.
4. Reboot the phone, use normally. Let it run completely out of battery.
5. Charge the phone back to full. Turn off phone. Charge until it says 100% on the green bar and vibrates for full charge.
6. The Important Part. Remove the charge cable for 0-0.5 seconds and plug it back in instantly. Let it charge to 100% again. Do this 1-2 times again, so you've done this 2-3 times total.
7. Reboot to recovery, wipe the battery stats again as on the step 3.
8. After wiping the battery stats, plug the charger back in the phone.
9. Reboot to ROM. Keep the cable plugged in. Keep it plugged in for about 30 mins to 2 hrs. Unplug. Should say 100%, mine did for about 40 mins after it depleted onto 99%. And this is the way you should really gain great battery performance.
************************************************** *********
First 2 times I drained it heavily, WiFi on, 2, 3 music players on etc. (charge up while phone isn't started).. The last 3 times whith a normal usage..
and charging while phone is running.. every time it says it was 100% and when I got the full-battery-notification, reboot into recovery.. clear battery stats..
************************************************** *********
1) Turn OFF phone
2) Charge till it says it is FULL
3) Start in RECOVERY (volume UP+Home+Power), here WIPE battery stats (it is in the "advanced" menu)
4) RESTART android (yes, it might already be on 98% or so)
5) USE phone heavily. Don't worry if it drops too fast. Use it till the Android system turns OFF automatically (it happens when your battery is below 1% - for me the phone was on 1% for about 40 mins. This is where it heavily miscalculated
6) PLUG IN your charger, TURN ON android and wait till it is FULLY charged again. (It is better if you don't use the phone at this charging up)
To follow all those instructions would literally take 2 weeks. No phone is worth that much effort.
It's not that bad just try the first option if that don't work, move on two the next one, really not two much hard work: )

Yeah I meant an abnormal drain on the magnitude of 70% with 1.5 hours of use and 4.5 hours of basically idle
just try this option

2. Switch on once more to make sure battery really is 0% (it will then immediately switch off once more)
3. Now, keep switched off (!), plug in charger & leave in charging until 100%

what apps have u got running,things like gps wifi turned on all time will drain battery life.

I can't find the "Advanced" menu in the Recovery Mode, is it there stock?
have you got ( clockwork recovery v2.5.1.3 ) installed you need this two use the option i give in the thread,if not try and install rom manager,i think rom manager installs cwm not sure ?
ps, has the phone been rooted,and is it stock rom or custom rom.
Epic Fail...
I've never felt comfortable with rooting or custom ROMs so I don't have any of that.
Also I just tried the 1st batch of instructions, except without the ability to erase battery stats I did a Factory Reset instead... the results: (I kid you not) 100-0% in 3 hours.
The screen's been on for 1hr 30min, with the phone awake for only 10min more than that
I'm really hoping the phone's just super inaccurate right now, and "critical battery" actually lasts several more hours... although I'm not sure how any phone could be that inaccurate.
I realize that calibration isn't supposed to make it worse, but this time it actually made it about twice as bad
Definitely just died...
when charged does it read 99% or 98% when u unplug the charger
When i use my phone with internet and downloading i get about 8 hour's of use,when on standbye,it will last for about 3 days, it all depends on what u use it for how many app are running,but for me just installed darky's rom 9.2 now get longer battery life, but still the battery life on sgs is really bad compaired two my last phone that would last for 7 days without charge.i would flash darky's rom would someone else flash your phone for u,or read up on flashing on xda they are loads threads about flashing custom roms
mark204
if you are thinking of flashing a custom rom make sure you have the three button combo working vol up home key and power buttons two enter recovery mode and vol down home and power for download mode,you need two have this before considering flashing any custom rom
Hey guys I just picked up the Thrill the other day, and like others I've realized the battery life is horrible on this phone not to mention when I reboot the phone would take a 10-15% out of the battery. Coming from an Atrix I decided to try the battery fix for the Atrix since it worked for me in the past, well after following all the steps in the guide it seems my phone reports the battery more accurate and battery life is better but your mileage will vary. Reboot doesn't take 10-15% out of the batter percentage either so here is the guide and link to the original thread, all credits go to xploited.
PS.. I followed all the steps except for flashing the jug6ernaut's CWM battery fix since it is for gingerbread roms
Link:http://forum.xda-developers.com/showthread.php?t=1198333
Guide:
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )

Not a bad process. I did something similar. Main part is Watchdog and finding out what's draining your battery. On my phone the infringing process is "Suspend". Now, if there were an app that was keeping my phone from suspending and running up the process it would be an easy fix but unfortunately the process with the highest "partial wake" battling my "Suspend" is the "dialer" so unfortunate I'm just gonna have to wait for GB since I have no interest in Rooting or installing roms at this point.
I'll give this a go. Thank you
