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.

It has some discussion about cog and battery life, but I suspect it might be outdated.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.

Hi,
I am trying to do the battery calibration piece but my phone never reaches 100% when the phone is off i charged it for almost 3-4 Hrs.
can some one help me?
New battery, like $10
i have two batteries now still i see the same issue, it started once i moved to GB Roms, before it was pretty good.
It is normal between 96% and 99%.
Is it normal to not reach 100% when i turn the phone off and charge it?

There has been talk about this occurrence before, but basically it's a battery-life saving feature of Gingerbread. Rather than hold your battery at 100%, which will decrease the battery's life, it charges to 100%, lets it dip down to a certain threshold (like 90%, for example), then recharges again.
That's my understanding, anyway.

Like jmtheiss said t's a GB surge protection not to overcharge the battery. It's a feature not a bug
does this mean we can do battery calibration on GB roms?

Two things regarding Battery Calibration :
1. For Better Battery Life : Always charge upto about 90% and use. Recharge when you reach 10% or even less. This will tremendously increase the life span of Li-Ion battery.
2. As regard to 100% charging :
(i) Boot to CWM, wipe battery stats.
(ii) Reboot and charge until 100%, Disconnect from charger
(ii) Power Off and connect charger again. Charge until 100%
(iii) Boot to CWM, wipe battery stats again.
(iv) Power on the phone and charge until 100%
Done.
Repeat the same, if you wish to re-calibrate the battery after some time.
Tip: Always re-calibrate battery and charge to 100% before flashing any ROM.

As I fiddled around with most of the ROMs out here in XDA, would suggest you to flash a KK4 build like Serenity or Illiminance, if you want a stable GB ROM. KK4 is the latest captivate GB leak and the ROM is awesome. Also, the ad-hoc wi-fi through modifided wpa_supplicant works in this build. The ROM is fast, stable and got good battery life. Try to flash the ROM and I'm sure you will get a great GB ROM without troubles.
Hit thanks, If I helped you out

Use battery calibration app from the market! Charge your phone with the drag method before calibration to get more runtime!

cant find it on google again ;-( but i explain it to you!
1.Charge your phone to 100% when it is on
2.turn phone off and charge again to 100%
3.unplug on 100% and plug in again (phone is still off)
repeat this prozess 4-6 times (to get your battery more charged)
4.reboot phone and charge again to 100% till your get ful battery message
5.unplug and plug in fast till you get again 100% and battery ful message
6.repeat this till the message of 100% comes fast (should not take longer then 20sec) then your are ready to calibrate
7.open battery calibration from the market and hit calibration button
8.unplug phone (done, almost ;-))
9.let your phone unload till 0% and till it turns self off (dont charge between or connect to pc)
10.charge to 100% again without break between (this is importand then the app will write new battery history)
11.on 100% unplug and your are done!!
sounds like stress i know but this method is realy effective to get more power in your battery! specialy after flashing some custom roms!
notice: cm does not have full battery message like emanoNv4!!
i explained how to make it with cm on next page ;-)

I never see the "Full Battery" message..
I never see the "Full Battery" message...
I'm using squadzone's CM7 v5.4 ,It was at 100% already for almost an hour.
I even tried unplug and plug in the charger.
Restarting the phone and charge again and still never see the "Full Battery" message.
When its off I just see the Battery and the running dots underneath but not sure if it was already full.
Battery Status shows "Charging (AC)" with the Battery Level 100%.

kinda same things happened with me. I'm using CM7 RC0 v0.3d.
never see "Full battery" Message when the phone is on.
But when your phone is off and showing "100%" I think that's right.

ok that cm not have this full message, skip step 5.+6. and make it of time!
if you reboot after step 4. plug in again and wait like 5min repeat that 3times
and the effect is the same only without message! then make step 7. till 11. and
your are done on cm!!
I reached the conclusion that all these calibrations techniques are just a myth.
A Google engineer already stated that the wipe battery stats simply does nothing in terms of calibration. It just removes the data that shows in the battery info (chart and usage by app/hardware). Guess what? That same file is the one that gets reset after reaching 100% and unplugging the phone.
Then no calibration technique explains why on many junky Samsung phones after a phone reboot, no matter if the phone is fully charged or not, the battery loses 5-6% of battery. One reboots the phone to reset it and save battery and instead s/he gets a battery drop. I just find this unacceptable. For much less the iPhone has been massacred all over the news.

it's simply because booting os consumes energy. it have to load everything, hence the drop...

Really? So why does it happen even if the phone is charging? Why it doesn't always happen? Why few times the percent even raises?? Why do I get up to 10% drops after a long deep sleep? But I don't get the same drops if turned into airplane mode (well, testing it just now)?
And regarding the energy consumed while booting, it is just a matter of having the CPU at 100% with the highest frequency for a couple of minutes. That barely justifies a 5-6% drop. Antutu battery test drops 27% every hour, less than 1% every 2 minutes. I don't see why the boot should consume much much more energy.
Honestly, it doesn't bother me that much. It was like that in stock rom, it's the same in custom roms, so I assume it's androids normal behavior. Phone's working, battery lasts for nearly 2, sometimes 3 days, so I can't complain about it
Well, in that case you're right not to complain. If my phone reaches 30 hours I must consider myself lucky. And that is with a (2430mAh declared, probably 1700mAh for real) Gold battery. But I don't have Mini/Pop I have a Mini/Pop Plus (actually Next Turbo in Italy), the S5570I.

That's the bug I was talking about. Wait for it to say "Full".
Currently Running
--> GingerDx V023
--> Stock Kernel.
I wiped out battery stats from CWM just after flashing the new ROM , but after calibration , and after charging the phone the battery gets mis-calibrated and gives me an error in battery percentage of about 20-25%
I calibrate again , and then again it mis-calibrates again.
To explain more , Suppose I have full 100% battery and I calibrate battery. I normally use my phone , and restart my phone after listening to music etc.
I get true and correct battery percentage every time I restart.
But when I charge my phone when it has about 10% battery , it charges up to 100% in about 50 minutes.
And when I restart my phone , it says I have only 77% battery left.
Mis-calibration is only when I charge my phone , not when I am using it normally.
I am not having problems with battery life as such when I finally manage to charge it to 100% after restarting my phone several times to actually get it fully charged (about 30+ hours of moderate usage after full charge) , but I don't get the true battery percentage on my phone when I charge , and my phone doesn't charge to its full capacity in one go.
I re-flashed GDx V023 three times , but the problem persists. I tried all calibration techniques and apps in the market but failed.
What can I do ?

Did you ever try to full wipe your system?
Try to full drain your battery after calibration,
maybe it will solve your problem.

Initiated full wipe each time.
Not tried full drain yet. Let me do it and then see if it works .
Sounds very much like a problem I encountered with my spare battery (actually, 2 spare batteries). It also appears to (in part) depend on the ROM. Stock ROMs don't seem to have that problem. Consider it a kind of tradeoff for whatever benefit you're deriving from your custom ROM.
Still not able to fix
Not sure what I can do.

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!
