Milestone battery stats?

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?

[Q] battery percentage not accurate

Hi Guys!!
i've done what this link told
http://forum.xda-developers.com/showpost.php?p=10092321&postcount=11053
but everytime i reach 100% and unplug the charger, my battery percentage immediately shows 97%, be it charging with the phone off or on....
i already did wipe my battery stats in recovery a few times, the first time only it showed that the stats were wiped, after that every time i wipe the stats, it immediately goes back to the previous menu, without stating whether the wipe was carried out or not....
can someone help this noob out here.... thnx

FYI, i just installed darky's rom v8.0 with Voodoo's kernel 5.2(lagfix disabled)
when i was on stock, my 100% could last me about nearly half an hour

I have this problem too. (I am on Darky 9.02 and have seen it in Darky 8.0 too). BUT if your battery life is satisfactory then don't worry about it.

hows the performance on v9.02 bro?

9.02 is good but then so was 8.00. I personally think 8.00 was faster but its only been a few days and am still experimenting. I may remove the lag fix and still need to see if my battery is draining faster.

Also look at this post: Has some interesting but unverified info about the drop from 100% to 97/98% after unplugging

Do you really want it on 100%? Easy, once it says charged, leave it on the charger for another hour and when you unplugged it should stay 100 for a while

Problem posted hundreds of times along with solutions like search the Rom makers forum and read the posts re this problem for starters .
Simple solution save time and effort is to ignore it .

thanx all for the advices.... tried the QueenAmy method, result is:
heavily used phone: battery 'died' at 2%(???)
charged phone until 100%(phone off)
switched phone on while still charging: 97% (didnt have to unplug charger)
waited...then it went from 97% straight to 100%.(funny)
then went into recovery to wipe bat stats.
rebooted and unplugged charger, battery still at 97%....
now trying to charge a bit more longer to see if can change anything... (fingers crossed)

not working bro...
left it on for about an hour, unplugged, straightaway the percentage drops to 98...

It's just a change in 2.2.1.
In 2.1/2.2, they 'stretched' out the battery life a bit to mark it up to 100%, in 2.2.1 they decided to just show it at the actual value. The reason your battery won't charge to 100% is to prolong the battery life, because if the charger always charged to 100% it would have a high chance of overcharging and damaging your battery over time.
There's no real change in battery life.

I reverted back to 2.2 and still have the problem. Maybe i shouldve flashed on 100% battery... Is it possible to solve if i do another fresh flash with 100% battery?

Just to clarify this, you actually cant over charge the battery on the SGS nor Li-Ion for that matter, what happens here is that the battery goes on trickle charge pre 2.2.1 and battery degrades faster if its kept at 100%, 40% is optimal for storage now with the recent changes the phone will pretend it has charged upto 100% but will stop anywhere from 99~97% yes there is no loss in battery life but dont consider 97% as the new 100%, theres already a 3% loss in this to begin with.

Charging the battery with phone off makes it last longer?

Havent you noticed that when you charge the phone powered off it takes like 40 % more time for the batetry to charge but it also makes the battery last longer? is there any truth in this or im just crazy?

This is a very well know issue related to battery calibration. Take a look at the many calibration threads to learn about bump charging.
Basically, it takes longer with the phone off (or when you pull and put back the battery while charging) because in some cases android was stopping the charge before a full charge.
Try this
Charge your phone to 100% (inside android)
Turn you phone off
Reboot
Pull the battery before it boots
Wait for the ?
Put the battery back in and notice the %
If it says 60%, then you had 40% of your battery not being charge.
If you leave it in that spot and wait for it to go to 100%, your battery will be better calibrated.

and this hasnt been fixed even with gingerbread? yeah i have gotten the message saying it has 60 % :/

I pay no attention to the battery meter anymore. I've found that it just reads low. It's not that it doesn't get a fully charge, the phone can't read the level correctly. I tried draining the battery once by playing an episode of Top Gear with the screen on full brightness. The phone said the battery was at 5% but the video kept playing for another 1.5 hours.

noup , when my batetry says low , it dies pretty quickly

Go with mV.
4200mV=100%
3200mV=0%

Method to improve battery life

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 )
Click to expand...
Click to collapse

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

[Q] just wanna ask x8 battery life

hello
i just wanna ask something about my battery life on my x8...here's how it goes first i fully charge my battery up to 100% until it says on status battery full...then i unplugged it..after it i texted for a few minutes...and i check the status of my battery and it says: 28 mins 23s on battery..my battery is on 96%..is this normal.? or somethings draining my battery,?
i use minicm7 2.2

this is normal since battery is heating itself while charging, and when it cools down it shows less percentage of itself... to maximaze your current battery life, calibrate the battery:
1. charge it to 100% no more no less
2. leave the charger PLUGGED IN, and reboot to CWM
3. there you should find somewhere under options or advanced "wipe battery stats", and you press that
4. reboot your device and when it starts up it will show about 91%, charge it to 100% and you have your battery calibrated
NOTE: the charger is always plugged in

ok thanks i'll try it... one question should i drain the battery before calibrating it.?..as in zero percent??

Yes , that is recommended.
Also , one advice from me.
Even after calibration , whenever your phone says 100% charged , reboot it while the charger is plugged. You will get the exact battery charge after reboot.
Do it every time your recharge your phone.
Then stop rebooting when you get a 99% or 100% after a fresh reboot. Trust me , it helps.

ok thanks for the advice i'll try that too...

it is normal dude ....mine is giving 1day on heavy use

use zepplinrox's supercharge script...it really made a CONSIDERABLE change to m battery usage time

I have one question: "Why my battery is giving 6-8h. My battery 2 days ago giving 24 and more hour." Sorry for my English, but i am from Poland

what happened 2 days ago? did you install new ROM?

The OP might not have needed to install a new ROM, just an APP or maybe just a combination of APPs running. My phone sometimes canes the battery in a couple of hours from 50% to nothing for no apparent reason. On both stock and custom (actually better battery life on custom) it lasts about a day but sometimes about 6 hours! Not sure what is going on as this happened on both the stock 1.6, 2.1 and the custom 2.3.4!
