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

I've been reading around and is anyone successful with the sequence of
--Charge Phone while on
--wait until fully charged.
--unplug charger
--turn off device
--charge until fully charged.
--unplug charger
--turn on device
--when phone is completely done rebooting turn off
--plug charger again until full
--turn on device and move on
and how does that relate with the reset battery stats on clockwork mod?
can anyone elaborate D:
I tried that method and i didn't see a difference in battery life. Didn't wipe battery stats through clockwork.
I did it the other day when I first saw the post and I seem to be getting better battery life. Could be a typical placebo effect, but my phone sat on 100% for a couple of hours after doing this (with negligible use during that time, except for my compulsive turning on the screen every few mins to see if the battery had dropped - using Fightspit's Super Circle Battery Mod).
The two slight changes I made from the posted steps:
1. My first step was to wipe the battery stats using ClockworkMod. No special knowledge here, and I have no idea if this was a good idea or a bad idea, but I figured the best way to calibrate the battery gauge would be to start the process with no history. I didn't want to add to the old history, I wanted to start fresh.
2. I did the "unplug the phone, turn it on, when it's completely on, turn it off, plug in the charger, charge with phone off until you get the 'full' message'" part an extra two times. Just because. The first "extra" time, it took a few minutes to get the "full" message. The second extra time, the full message was pretty much instant and I was satisfied. I do not recommend doing what I did, because I have no idea whether it could ruin your battery in the short- or long-term.
Also note that my phone had a 43% charge when I first started this process, I didn't drain it until it turned off like some other calibration processes recommend.
Since I did this, I have just been letting it charge regularly overnight (phone on, plugged in) and it feels like the battery numbers drop more slowly with the same usage pattern.
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..

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

Do it this way:
Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!
You will see the difference. I get from 1 day before to 3 days now.
For doing this, your phone, of course, should be rooted.

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?
My battery never charges above ~76% when plugged in. After rebooting however, it is very much at 100% and lasts for a good amount of time. This is not necessarily a question, but I wonder if others are experiencing this too and if there is a fix? Read below.
I noticed that my battery life got very bad after installing custom roms. I also found out that this happened because I sometimes kept the phone plugged in while flashing, something that totally screws up the battery reading. So, I followed this guide to calibrate my battery and it worked.
Now, whenever the phone is plugged in it NEVER goes to 100% when charging. Maybe 80% if leaving it for a while (10 hours overnight). I'm worried about frying the battery. Is there a fix?
It is only a matter of presentation. It actually doesn't mean your batt is broken. Plug it and charge it overnight. Then discharge only for few percent and plug it back in. It should go to 100%.

Thanks, I'll give it a try.
What I'm concerned about is if the phone "thinks" the battery isn't recharged and keeps squeezing juice into it when in fact it is full (which a reboot will show)? That's not good for the battery. It should go into trickle charge after reaching 100%..
The process described in the desire forum is also known as formatting the battery. In fact most of battery manufacturers (lithium battery manufacturers) recommend doing this in a slightly different way:
Before first use:
1.) Before powering the device on, plug it in and let it charge until the LED is green (fully charged)
2.) Then take the battery out of the device and wait an hour (to make sure all the chemical processes in the battery are as idle as possible)
3.) Then plug it back in, while still off and let it charge untill green LED
4.) use the device....
You can practice this slightly modified with first step being:
Discharge the battery (by normal use)until only few percent are left (1 - 5 % are OK)
I've done these steps with my Mugen extended battery and I was getting around 4 - 5 days on Legend, now I'm getting 2 - 3 days on Desire S, but the ROM isn't very optimized yet, I believe it will be better in time...
Just one thing... Why is this in Development!?
No Idea.....
can mods move this?

Definitely did not solve it but at least the battery performance is ok. It just stays at 78% for a few hours drops from there. Very weird but as long as the battery doesn't get broken I guess it's ok.
Do you have some 3rd party battery installed in your Legend? I have one 1,5 Ah in mine and it is acting the same way. It doesn't bother me too much coz it was cheap... it lasts 48 hrs with data always on and moderate usage. I noticed this that when I charge it overnight and it reaches 80%, unplugging it stays at 80% for several hrs and just after it starts dropping if I plug it again, meter reaches 100%. It's weird but as I said I can live with that
I've got exactly the same issue with stock 2.2 ROM. I've never rooted or CM my phone; I was wondering if CM would do it, but doesn't look like it.
android forums /htc-legend/265545-battery-doesnt-fully-charge.html
(sorry, I can't post links; maybe an admin can fix the link for me?
This seems to indicate it's a phone hardware fault and requires a new Legend to fix! My big worry is, as stated, that the charging light never goes green; therefore is pumping lots of power into a potentially full battery.
Hey all,
I have had terrible misfortune in the realm of battery stats. Ever since CM7 (and maybe even before) my phone is unable to figure out how much battery is left. Here is a common scenario:
Charge phone overnight, use phone throughout day, battery dies after 6-7 hours of moderate-heavy usage. I plug it in, reboot, and then it reports ~60% battery left.
Another common scenario is that it will dwindle around 5% battery or less and go up and down until it finally dies.
I know that this is a misreading of the battery and not battery drain or a rogue app because when I flash a new ROM the battery life is amazing for 1 day. The day after I flashed Team Hacksung's ICS rom, I got almost 17 hours of battery life with 2.75 hours of the display being on and 30 minutes of Google Music. I was blown away! But even then it was dwindling around 5% not knowing when it would actually run out. The day after, it was back to its old tricks of misreporting the battery percentage.
Today I charged it to 100%, unplugged it, and shut it off. Then I plugged it in while it was off and let it charge to 100% again and wiped battery stats in Clockwork mod. I'm getting ok-ish battery with that, but it's not even close to how good it was when I first flashed ICS.
Anyone have any ideas what I could try?
Thanks!
When you wiped the battery stats did you let the battery fully discharge and shut off before charging again?
After wiping battery stats it is recommended to let the phone fully discharge to the point where it will automatically shut off.
Keep in mind with the age of our phones, it could just mean your battery is dying. Try the above method, but in my experience uncalibrated battery only last a few days. The phone will "fix" it by itself the longer you use it.

That's what I'm doing currently. Battery life seems improved, but we'll see what happens. It's nearing death now, ~6%. At this point it will probably misreport it for a few hours until it finally dies. I left it unplugged overnight, so now it's at 19.5 hours uptime with 1.75 hours display time.
Definitely improving! I hope that it successfully recalibrates.
Battery stats have nothing to do with how the os calculates remaining battery...they are what is displayed in settings>about phone> battery use and are reset each time you charge to full.
You're just giving it a good bump charge...wiping the stats is just a placebo effect.

Seriously? Wow I didn't know that. Is there a way to actually reset how the OS calculates the battery?
Does this app do anything?
https://market.android.com/details?...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
Nope...that app is just perpetuating the myth of what the batterystats.bin file does.
Don't hate me for this but, Then how come Roms usually give me better battery life after a full cycle? not bump charging or deleting battery.bin just running it?
Because the system for tracking the remaining power is getting to know your battery. once it gets a feel for it, it's more accurate. In theory anyway
So the "give it a day" is still true, at least in theory?
Sure

battery gauge temporarily fixed by removal and replacement of battery
Ever since I rooted my phone, I've noticed that the battery gauge/meter is way off. I keep an eye on the charging voltage and try to pull the plug around 3.92 volts. Problem is, the gauge is always reading low until I pull the battery, wait a few minutes, and then reinsert and boot up. Then it's fine for a while, but I notice it creeping down even though I keep topping it off with a charge to keep it around 3.92 volts.
What's going on? Do I have to fully deplete the battery and charge to full to have an accurate (or somewhat accurate) battery gauge? Do I have a bad battery (this battery has been used only a couple months)? Is something else going on here? Recommendations, studacris? Doesn't the os use battery voltage to calculate state of charge (%)?
