Hi there,
I have had my SGS since Sept 2010, and have had no problems. A few days ago, the battery standby time dropped from a few days to 5 hours (and this was in flight mode). With the 2G phone on, and 3g/wireless/gps off, the standby was about 3 hours.
I removed the battery, and the put it back in, and let the 'phone charge whilst turned off.
Is there a way to mend this? Where does the problem lie?
Cheers, Peter.

might be due to a new software you just installed or upgraded.
Install some free tool to do the monitoring and confirm which application partially awake or prevent your phone to go to sleep mode.
Try System info
Exactly the same problem with me, I'm pretty sore the cause is update or app.
This is not the case. no new programmes were installed.
I noticed that when the phone is ON and charging the indicator states it is e.g 30% charged. I remove the battery charger, and the indicator states that the phone is empty and has to shut down.
Huge Battery drain post on this very forum worth reading .
But i would hazard a guess with a sudden drop its a dying battery .
jje
I had the same problem with u, i think u should back up your phone's data then use "Factory data reset" feature. I did that and everything's OK
SOLVED
Indeed, I did a factory reset and the problem went away. Battery life returned to normal.
Thank-you for your advice.
So somehow my phone did not like the Froyo update, would not boot after install or even a factory wipe.
So Verizon swapped it for a refurbished one, Ive had it for 5 days.
It had 2.2 installed when I got it. However the phone is almost useless for me now, It wont last a full day with nothing on, no GPS, no WiFi, no mobile data, no apps running, only turning it on once or twice during the day to check things and each time I do the battery draining like crazy!
I used to get 5 days out of my old phone, literally, because I am not a big user. I actually did play with the phone the day after I received it, to personalize it, and I drained 50% of the battery in an hour!
This is the same battery as in my phone, you dont get a new battery with the replacement.
I think its a hardware problem with the phone, but a guy at work says its just the 2.2 update, that it slams the battery.
Im going to take it back to Verizon tomorrow and see what they will do for me. If they wont fix this, I will simply revert back to my old flip phone since it lasts 5 days and cancel my data plan.
Keep on them to get that one replaced. Something in your hardware is definitely borked.
Even running WiFi hotspot, I don't see anywhere near that kind of drain (50%/hour). At the very worst, my idle drain was about 9%/hour.
This is not a good thing.

You need to make sure your old battery is calibrated to your new phone.
1 - install CWM recovery.
2 - tonight when you go to bed, power off your phone (power off is not screen off). Plug in your charger and charge overnight, USB charging prefered over wall power charging.
3 - in the morning when 100% charged battery is indicated, boot first into CWM recovery and wipe battery stats, after which boot back into Android then you can check for battery longevity again.

Wiping battery stats seems to be a placebo effect. For anyone with serious drain (several % per hour), wiping battery stats does nothing. Its a shame so many threads are corrupted with this misunderstanding when there are other very real sources of battery drain on froyo ROMS.

It's perfectly normal for some people that wiping batterystats.bin did nothing useful, it's also perfectly normal for others to loose 1/3 of battery capacity from being uncalibrated.
It's definitely perfectly normal for some to loose 10% per hour from being uncalibrated.
This kind of variance often confused people.
After doing some experiments, I think its Froyo.
The reason is I turned off mobile data and the battery only drained 2% in 3 hours. Then I recorded some vids of my daughter and played them back with her and over those 3 hours it only dropped 6%. Seems pretty reasonable. I know in my original post I said I had mobile data off, but I realized I actually hadnt, sorry for the confusion.
So I turned on WiFi and GPS overnight and it only dropped 4% overnight.
So something in Froyo is sucking down huge amounts of battery when mobile data is turned on.
Or its still possible its hardware related, that the data radio runs non stop when its turned on, just seems unlikely.
A guy at work suggested turning off data roaming and turning back on mobile data and seeing what it did.
I've had my phone draining at about 10% per hour before, never did figure out what caused the problem. But I flashed back to stock (following the instructions to get ED01 by flashing back to DL09 and then running the update.zips), and that seems to have fixed it. Since 2.2, I've stayed largely stock - stock kernel and just debloated the stock rom. So far, that's what I've found to give the best battery life for me - 48 hours on a charge on average.
Few things to do/keep in mind:
Clearing the battery stats might not solve the problem, but it can't hurt. Charge the phone to 100%, then turn it off but leave it on the charger. Once the powered off battery indicator on the screen shows 100%, boot into CWM and wipe battery stats. Take it off the charger, turn it on and use it normally until the battery gets down to 5% or below. Charge it back up and you're good to go.
Also, give it a few days/battery cycles to come up to full capacity. I seem to notice shorter battery life immediately after a wipe, but after a few days, it's back to the normal 2 days or so between charges.

Definitely seem to be software problem instead of hardware, I suggest leaving everything on -Wifi, GPS, bluetooth, etc... and disable all data sync only one at a time to check for power usage.

Load up Spare parts and see what it says in Battery History. Under 'Other Usage', it should show that running is less than 100% (depending on your usage patterns, this could read anywhere from 10-90%, but it should never show 100%). Do this after having been unplugged for a while.
If running shows 100%, you have a wake lock, which is forcing the phone to be awake 100% of the time, rather than sleeping and using much less power.
You can use dumpsys power from an su terminal or adb to look and see if you have any locks.
If no locks show up, and running still shows 100% (or even if it doesn't) with mobile data on, then there's definitely something wrong with the data radio, and you should have it swapped.
Don't accept any other answer from either phone CSR or in-store rep. No matter how they try and excuse it, constant 10%/hour and up to 50%/hour drain is completely abnormal.
Ok this is what spare parts says
Running 5.2%
Screen On 3.1%
Phone On 0.5%
Wifi On 77.2%
Wifi running 55.6%
Try this, it will tell you what it causing the drain.

Is that with Mobile Data on? Are you still seeing 10%+/hour drain with those stats?
If you're seeing that kind of running time (which is good), and you're still getting huge drain (which is bad), then your phone is broken and needs to be replaced.

Thats total since all time.
So I had the phone all weekend with wifi and mobile data on, then one day with wifi off, then one day with wifi on, mobile data off.
But the battery was consumed the most with everything on, but still very high with wifi off and mobile data on.
Unfortunately a refurbished phone must be returned within 14 days if there is a problem with it. The remaining time on the 1 year warranty is voided.
just use stock rom DI01package3.tar.md5 and battery is very good for me

According to the OP, you've had it for 5 days as of yesterday, which leaves you a full week+ to get it swapped again.

50% in an hour.. even if u use it the whole time is ridicuoulous.. prob a junk batt.. what are batt temps getting to??
There is a setting in the WiFi area to have the WIFI automatically turn off when the phones screen turns off, you may want to look into it

amazing performance great bat life runz like a dream!!
I just want to report that I've been having similar experiences, and in my case it seems associated with signal strength.
If I'm at home all day (where signal is good, and I'm on wi-fi), my battery life is pretty good. Not as good as it was on 2.1, but acceptable.
But if I'm out driving around, or in a place where the 3G signal is weaker (maybe 2 bars or less, but I haven't really verified that), my phone gets uncomfortably warm in my pocket, and battery usage becomes horrible. I've had the phone drain from full charge to 20% or so in less than two hours.
This problem never happened before I flashed the DL30 Froyo leak. Since then, it has happened on every Froyo ROM I've run, including official ED01 and the community ROM.
Hi
I have recently started having a problem with what I presume to be the battery of my Nexus 4. It seems to have started suddenly about a week ago, though was working absolutely fine before. I don't think it was due to any specific app having been installed. I have also done a factory reset on it, but that didn't solve the problem.
Basically, the battery will discharge to about 75%. The phone will then suddenly switch off; turning the phone back on, it simply shows the battery to be fully depleted and switches off. If I plug it into a power source, the phone turns back on and begins charging, from 0%, though seems to suddenly fully charge it within about half an hour.
My phone has not been rooted.
I would really appreciate any help/advice on this issue as it is incredibly frustrating having to have my phone almost permanently on charge.
I have attached two screenshots of the battery usage graph.
Thanks!

If you are on stock, try flashing the stock image(4.2 or 4.3 up to you) there's plenty of threads on here thatll guide you thro the process.
I've had the same issue about three times, during the first week of using my Nexus 4 (about half a year ago). I've already had my mind made up to RMA it, but waited for it's shut-off to happen once more to collect some evidence of this problem and... it never happened again. I'm pretty confident that I didn't install anything that might have helped (I only installed BetterBatteryStats to check the instant drain, but really doubt it could change anything, it's just statistics), and I've never factory wiped the phone's data yet.
I've been searching for answers around the internet back in May, but never found anything of value, so my only advice is... wait a little, and if it doesn't get better itself return it to the merchant. My previous HTC phone was restarting almost everyday from the first day I bought it, until a month later I returned it for warranty repairs and after they changed almost all internals of the phone it never crashed again (till today, since I still use it as GPS and media player when running).
