I've been using several custom roms on my Defy green lense and i noticed an issue with the battery life.
It happens that every time i fully charge the phone, when it goes to 70% battery life it instantly drop to 50%, battery drain, even with STOCK Froyo.
But if i charge it to 69%, not fully 100% or over 70%, it goes normal...
Is the battery bricked ?
kid...
first, bricked usually mean when you somehow made the phone into a unrecoverable status.
second, vertical battery drop (e.g. 70%-50/40/30%) is almost always a sign of an aging battery. just buy a new one. or you can keep using it if it lasts long enough for you, you don't really have to worry about it.
You could also get Batterymonitor widget pro and let it listen your cycle process and then calibrate it according to your real battery voltage and then you'll have no drops anymore...

I've had this phone for a while, and i just haven't been using it the past, ohh year? I tried a while back to fix it, and I know it's something to do with my phone/it's battery, It can stay in standby for about 26 hours, (no wifi, no sim card), but any phone call or wifi use lasting over ~5 minutes and the phone dies, but the phone reports that it still has about 30% battery left as it's shutting off!
Is it possible my phone isnt allowing my battery to charge fully?
I remember reading somewhere about the phone storing battery stats? I wanted to give fixing my battery one last try before I break down and order a new one :/
it's running CyanogenMod-4.2.15.1 (firmware 1.6)
so it has whatever ancient recovery comes with that, I would upgrade my phone but I don't trust it not to die during a flash and brick it.
To sum up the wall of text, my battery is dying from 80% in <5 minutes when not plugged in, and it dies when it says it has approx 20% battery left.
The battery is also sort of bulgey, perhaps, it's like 5/4 the size it should be? 9/8? , it makes a tiny bit of a bulge appear on the keyboard too.
Edit:
The recover has a green carebear with a nexus one logo on his (her?) tummy. RA-dream-v1.6.2
Same problem on official 1.6 rom + root. Battery or charging problem?
Certifiably battery here, i tried with my dad's battery and it seems okay, but i'm not entirely sure because i didnt have my sim card in it to test its usage lifespan
My G1 has terrible battery life, even when I'm not using it, I think the best solution is to buy a new battery

Yes I'm agree with AndyFox2011 view.Purchase a new battery .
Hm. SHould i get this battery:
http://www.amazon.com/Li-lon-Battery-HTC-G1-Google/dp/B001ZTZ92E/ref=pd_bxgy_cps_img_c
Or this one:
http://www.amazon.com/Extended-Capa..._1_2?s=wireless&ie=UTF8&qid=1316633929&sr=1-2
or this one?I've heard more about this one than others I'm hesitant though, because i love having the hard cases on my phone, and i'm not sure it would fit
http://www.amazon.com/Seidio-Innoce..._1_3?s=wireless&ie=UTF8&qid=1316634086&sr=1-3
or is there another low cost ($20 or less) battery that you would recommend?
I'm no expert, but I'd go for one of the extended batteries, they'll last a,bit longer than a normal one

You should down the brightness.
I have CM7.1 on my MT4G. Over the past week or so, my battery has been dying after 2-3 minutes of use. I'll get a full charge, take it off the charger, use any app(Angry Birds, Gtalk, text messaging...) and the phone will shut itself off after just a couple minutes of use. When I turn it back on, it says 2%-3%. It then shuts itself off again, I plug it in and turn it on...says anything from 3% to 90%.
I've always ran the battery down and charged to full. Is my battery kaput? Is there a way to fix this?

Most likely.. take out the battery and inspect for leaks(might be very small discharge you might not see it clearly leak can and will damage your phone)..let it die completely, and let it stay off, charge it till the green light comes on, reboot into recovery, clear battery stats, reboot and see how long it last, also change your brightness, and other settings that might be consuming battery use..if none of these helps.. just buy another battery.
Sounds like your battery is screwed. Just buy a oem battery or get a mugen power 1650mAh

My issues aren't quite that bad, but after I upgraded to CM7.1 from 7.0, by battery has been terrible. 15-20m of phone calls over BT takes ~20% of the battery. 15m on Angry Birds chewed up ~40% of the battery. I downloaded the latest nightly (252) and will see what happens.
Try a dif battery and see if it does the same thing. So you can rule things out

Mines also been horrible since I went from CM 7.0 to CM 7.1. Not sure whats up but it dies in like 6 hours on standby. the battery use app shows that most of the battery usage is by "Cell Standby". So effectively, doing 'nothing' is eating up the battery?
~Phil
I guess I'm not having the problem you guys are having with battery drain. Granted I didnt use my phone that heavily, but still sitting at 60% after 10 hours. But if your battery is dead after 3 minutes something is seriously wrong, I agree and try a new battery.

You need to calibrate the battery after changing ROM's. Download a battery calibrator from the market. (Don't pay for one. There are like 10 free ones)
Charge the phone fully overnight. Calibrate it in the morning.
Give it a few days to gather new battery data, and then enjoy getting a full day's use from the phone.
Update
So, it's gonna have to be the battery. Recalibrated, no good. Tried a few different ROMs from CM7 nightlies to MIUI, no good.
Waiting for the new battery to get here to be sure.
Thanks for all of the help and advice!
same problem here
hello there, i got 2 mytouch 4g both running the same rom (virtuous unity 2.39) one of them has eaten 2 batteries that i bought thinking that the batteries were somehow broken or damaged... i came across this thread, read the reply recomending battery calibrator when i reached for my phone (that i left sitting on my drawer waiting for a new batt AGAIN) to give it a try and to my surprise it was still on and i has been on for 2 days 11hours and the fricking battery was at 97% before that it started to turn off-discharge so i put the thing on airplane mode and there it was till now... dunno why or what but i think it has something to do with the radio/network... hope we find a cure for this
I've been having this same issue, and I was wondering if replacing the battery fixed the issue? Thanks.
Hello, as tittle says I use my defy with cm7.1 fine it runs the battery down at normal pace (around 10 hours heavy use then gives me my warning at 10% and flashed LED then down to 1% .
That's good right?
Problem is at 1% then I can carry on using it at 1% for about 2 hours (so far) it wont die????
I even got a battery drainage app and that ran for over an hour.
What can I do?
Is it a miracle?
defy cm7
Try battery calibration.
at 1%... just keep doing something till it actually turns off... then charge the battery till it reaches 100% without a break.
I got the same issue with CM7.2 nightly. It was solved for me performing the battery recalibration, as darshaonline suggested. To do this, just follow the steps for 'Battery recalibration in the Cyanogenmod Wiki'
me and some of my friends have the same problem. we all have 2300 mAh battery, but the phone reads only 500mAh, so it shows super fast (30-40%/h) draining, but when we reach 1%, we can carry on using for about a day. we couldnt find any solution to get the battery capacity reading right, the only thing we could come up with to find out the current charge was to guess it based on the battery voltage. our range is from 3,2V to 4.2V.

So i recently flashed CleanDFT ROM, first couple of days the meter read out 1 day and 18 hours which im very surprised then it went down to 1 day and 4 hours, now this morning i unplugged and it tells me i got 19 hours left from full charge, should i go by this? or is there something wrong?
hello can you help me wid flashing...i came from android...no idea of how to do it...

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.
1) Charge ur phone while off untill u reach 100%
2)Remove the battery but dont unplug the phone from wallcharger
3)Reinsert the battery, you will see 0%
4) Let the battery charge, when reach 100% power on the phone without unplugging wallcharger.
Now should be all good
you are kidding right ?
This is the one of the worst advices I've heard..... Overcharging the battery is dangerous.
It will actually degrade the batteries performance
I don't know what to say. Does this work?
Also by battery jumping do you mean those crazy drops between reboots or just drops due to lack of deep sleep?

U know how the LIB works? How Android manage the battery?
Try yourself and see! This is not overcharging

Btw the drop between reboots
Battery bin tracks the battery usage giving an estimate of the charge been used, battery .bin gets wiped every time it get to 100%, and the tracking of battery's current starts
As I remember lithium batteries charge in two cycles
1- constant current
2- constant voltage near the full capacity.
But then if you trick the phone to read battery as 0% then you are sending more current to an already full battery overcharging.
The jumping of battery percentage is because a bug in the battery "gauge"
But as always if in wrong, my apologies and I'll be more than happy to read your source.
Biggest issue is that the battery has a very poor C-rating, and has huge voltage drops under heavy load. The reboot battery problem comes from this; when you reboot your phone, or other times as well, the heavy usage spike drops the battery voltage down. Android system them detects this low voltage and just assumed the battery is almost empty. Normally there is some averaging going on to remove these spikes, and even then the battery % only goes down, so when the voltage recovers it just shows the same % for longer. Problem when rebooting is that it only sees this low, under load voltage and acts accordingly.
If the voltage isn't low enough so the phone shuts down, you might get 30minutes of screen time while the battery is showing 1%.
My problem is that the last 14% of my battery lasts under a minute before the phone shuts down. So I just treat 15% as actually meaning 1%.
Also, you can't dangerously over charge the battery, it has protection circuitry built in, and the li-ion charger part will detect the real voltage. This "supercharging" does however cost some long term lifetime from it, so it shouldn't be done too often.
Please excuse me, this is long.
Hello guys. I need some advice. I use I9195.
From the past 2 weeks i am facing serious battery drops
while phone is in standby.
I must mention that in the last 2 months my phone accidentally dropped onto marble floor 4-5 times.
Each time i checked to see if everything was working and everything did. But from the last time i dropped i began to notice this battery drain.
I made sure all hardware is working.
No problem with display even after all those drops.
(only minor scratches)
Earpiece, 2 cameras, speaker, mic, wifi, bluetooth all work fine. Network quality is great. This is the behavior with any rom, any modem and any usage.
When in standby, battery drains upto 2-3% every hour.
No background apps/services , wakelocks or anything that keeps device awake. And yet the drop is steep and is solely due to "cell standy".
I have no screenshots but here is a scenario :::
From 98% to 33% in ,
16hrs usage, 1hr33min awake and 1hr16min screen on.
Wifi enable half the time and 3g data was disabled.
EDIT :: New battery did not solve this drain.
Hey guys. Please suggest what should i be doing.
Read post above. Can new battery help ?
Thanks. [emoji29]
Same problem here i also need help.
From GT-I9192.
My phone dropped 5-6 times and .org works fine now.
