About to buy a new battery for my CM5.0.7/Danger G1. Just put in the new battery and charge it all the way (with device off) and then power on, or charge fully then wipe data then power on?

You are changing the BATTERY?
Battery will NOT affect internal storage.
I mean should I wipe the Battery Data or just charge that bad boy up.
I know batteries don't affect internal storage. I'd like to think that everyone knows that, but if you feel the need to tell me, I guess you have encountered quite a few "amateur coders" in your time.
But, yeah...any benefits to wiping battery data first/after charging?
Same Question here :/
after purchasing new battery, for sure it has a lil charge.
so what u must do is, drain the battery till it runs out of charge
and then after draining, its the time u will charge it.'
in sort, u will
1. drain the batt
2. fully charge it (while device is off )

I'm changing my s7 battery also... so no wipe to battery data?
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

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
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%

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

change modem file,or filmware i think js5 is good filmware(stoke) ,or if you like install superpower application that will help you to stop drain bettary,but its complicated,good luck

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
I never had this problem until recently i've flashed to Cog 4.
It started after i did a full charge. It discharges to 80% and to 50% and to 20% and to 5% and then died off within an hour. My phone heated up even though when it is not active.
Now, after changing a new battery. I find that i can't charge it above 85%. I re-flashed with Phoenix and Serendipity. The maximum charge still stays at 85%.
I've cleared the battery stats and nothing changed. I need help here.

http://forum.xda-developers.com/showthread.php?t=806211
It has some discussion about cog and battery life, but I suspect it might be outdated. Either way, it should have good info for you on how to get the battery fully charged
First of all, with custom roms, battery drains much quicker than normal, but i think you need to do a calibration. Charge your phone for like 12 hours to make sure its completely full, then drain it all the way until it dies. Then make sure its completely dead and wont turn on (sometimes the phone thinks the battery is dead, but its not. To solve turn on and off until there is no more responce. Take out battery, then try and power on. This will get rid of any static charge in the phone. Put battery back in and charge for another 12-15 hours to make sure its completely full. Go into recovery and wipe battery stats. Then let it die. That should do it.

yes and no.
custom roms wont necessarily use more power, in most cases less. and technically most power consumption is controlled by the kernel, and secondly the installed services in the ROM. new kernels useually come with a new rom but you dont have to keep it or you can upgrade it ect. But yes, when changing the kernel either by itself or with a rom you should reset battery stats.
I suggest drain it dead, plug it in until it is full, reboot into recovery and wipe batt stats (or use SGS tool script) WHILE PLUGGED IN, unplug.
or if you have an external batt charger, wipe batt stats in CWM then put in full battery.

When I said custom roms i meant that when you are on something other from stock. And for the most part, unless you are on a minimalistic rom, you do get worse battery. It is a known fact. Sure I have gotten 50 hours out of a rom/kernel combination, but it was never consistent. I had to flash back to stock and masterclear because i have random shutoffs and need to return it, and im seeing easily 30 hours out of stock with 3 hours usage of web email phone. Maybe its not the same for you, but stock has had the best consistent battery life for me.

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...
