Just curious what you are seeing under "Time without a signal %" which you find under Settings - About phone - Battery - Battery Use - Cell standby.
I have a Hero that is rooted and running 2.1 and showing 50%.
Thanks
%5. It was %70 before I did the charge in airplane mode trick.
I did the airplane thing too but mines at 0
33% for me. Did airplane mode trick and haven't had a restart since then.
50% here on rooted 2.1 as well.
What's this battery airplane mode trick?
31% after leaving the phone plugged in an not touching it overnight. Up time 68:49:32 and Awake time 16:41:50 if you need that too, as there's been issues of 100% awake time as well. Of course I've done the airplane trick before, and after a restart, it was back to 100%. Then found out that Meebo was the cause, as it was keeping the phone awake connected to all my IM accounts. Turned it off, and no more 100% awake time, and no more problems.

So i have found one solution thanks to a thread over at another site....
Seems as if there is some sort of bug with with Cell standby that causes the phone to lose signal which in turns just kills the battery. To verify that your set has the problem, check the Cell standby info in the Battery Use info. If the Time without a signal is higher than 0% (50% seems to be the norm) than you have a problem.
One solution, at the moment, is to follow these steps:
1. Plug in phone charger
2. Put phone in Airplane mode
3. Put phone to sleep for a minute
4. Turn off airplane mode
5. Unplug phone
I can confirm that this works and my Time without a signal is at 0% for over 9 hours now. The battery life is MUCH better and the phone didn't die on me last night while i was sleeping.

I am at 15% after airplane trick...My awake time is 78 hrs and some change so i think its pretty accurate. let the phone battery drain down and then put into airplane mode. Do a full charge and restart phone...then turn airplane mode off.
50%, geeze... doing airplane trick
After implementing the "airplane mode" method, it says my time without signal is 0%.
my show cell standby 12% android system 58% is this normal
yes another.
Is it necessary to drain the battery and do the "fix" or exactly as the quoted text states? I have tried, and my signal strength is a dot and the standby after is now at 23% from 17% right after, is it going to climb from lack of use or is this not resolved?
Your help is appreciated.
I have found that doing the Airplane mode on, sleep, then Airplane mode off will work without having to connect to a charge. The only thing the charge seems to do is reset the cell standby number. This makes sense since the percentage is based on when the phone was last connected.
What will happen is your percent number will keep going down after the "fix" which is what you want. If having a number really bugs you then add the connct in there.
My time without signal was at 50%. After doing the "no connect" it is showing 13% after 3 hours. it was 28% an hour ago.
Ok thats what I was thinking it was, on a bit of a side note, I no longer go to a lock screen when I press the Power button, i went ahead and set the display to something like 30sec but what just happened?
Works for me
I tried this and it works for me. At most i have 5% and by an hour later its at 0%. Thanks for the tip.
Rooted, running 2.1 rom v0.5.4
23% for me.
I had 50% also but had not really noticed any worse battery life.
Just so it's clear,
the airplane trick needs to be done EVERY boot.
If you restart your phone, you have to do it again. Every time.
Is this bug a result of flashing a specific rom or leak, or is it because of a specific radio?

I previously made a thread regarding low battery life.
After a week of use and more testing, here's what I gathered.
(Note: I have GPS, Bluetooth, Wifi always disabled, brightness lowest)
My phone will completely drain out in 6-7 hours.
I found the culprit: Cell Standby
1.) Cell Standby always uses the most battery, often 60%+.
2.) Phone Idle often follows with 30%+.
So, to verify my theory that the screen isn't the issue, I turned on airplane mode.
I proceeded to watch a 1 hour comedy, and battery life dropped from 60% to 50%.
This is lower battery usage than if it were sleeping with cellphone on.
I then noticed that my signal hasn't been good (provider sucks, no choice, all of em here sucks).
So, I placed my phone on, but asleep inside a locker for 2 hours (no signal).
When I took it out, it was very warm at 40+ C and battery life dropped about 20-30% per hour.
I've tried turning 3G off, turning always-connected off or downgrading 2g.
The result has always been the same. It still sucks bigtime.
It seems like Nexus One also has this problem, anyone notice similar problems?
I've googled and been told that this is "normal", because the phone increases power to secure a signal.
However, I've clearly owned phones and placed them in signal-less lockers prior to this, and trust me when I say most of them drop 5% per hour max.
20-30% per hour is horrible, and clearly the phone is overpowering its components.
There are some certain Radios you can flash to improve how your phone uses power to pick up a signal, Requires root access tho.
Can you please point me to those radios? I've already tried updating my radio to latest.
My phone is already rooted.
My battery is a joke and I have tried many different things. I always have to charge it by around 3pm everyday during week as It will almost die on way home.
I take it of charge at 7.30am by 9.30 it could be down to 86% and then it judt continues to drop by 3 It can be between 60 and 50% if lucky, by time i'm tenmins from my house I get 15% and warnings.
I use basically for txt, some net usage and sometimes playing a game 10 - 20 mins tops and or read ten mins of books.
I have all updates off only manual and screen down low etc - doing my head in!

Strange, I always have 3g on, and still play a lot with my hero (games and such)
Still it survives about 36 hours on 1 battery load. Without 3g it holds out for 72 hours.
Post #1 on the thread below seems to have a working solution (re-interpreted below)
It seems to be something to do with the battery stats and charging via usb through PC instead of via the mains.
You have to clear your battery data when your phone has really really low battery (this is probably the MOST IMPORTANT step) (you can do this through recovery mode in amonRa). Once the battery data is clear, switch back on (before plugging in) and drain the battery so that your phone switches off by itself (playing music loud and switching wifi, data connect etc, etc is suggested in the thread).
Once battery has died, plug in your phone WHILE it is STILL OFF, then when the battery shows green (will probably take longer to charge because this time it is getting a full charge), UNPLUG BEFORE you switch it on. and you should notice the significant difference. - Oh yeah make sure you switch off all those data connections and wifi and all those other things that you used to drain the battery - unless you use some of them of course
EXTRA TIP given on the thread: TIP!! Remeber when changing and flashing new roms to unplug the phone from charge *(i.e. unplug from your PC) (edit Bad4ss) * after you boot!
TO answer LennyUK's Q below ( and so that the next page doesn't start to quickly before this suggestion is read ) I think why it is suggested for the first boot after this process to be done while off is because it is already off because of the drain AND because it will get a clean full charge up for the first time after a battery data wipe. Because while it is on it will be depleting the battery even if it is in a small way - after that you can do it whichever way you want *nudge-nudge-wink-wink-say-no-more*

I don't see why the same thing cannot be achieved by charging with the phone on, just as long as you don't change between phone being on or off during the charge i.e. if you start charging with the phone on leave it like that the whole time and visa versa

Can you do this on non rooted phone? How do I get into recovery mode?
I think the analysis is flawed. I also think the stats information doesn't tell you everything. For example, yesterday I had 60% cell standby, 20% WiFi, 20% phone idle. Consumption was 45% in 24 hours.
Previous to yesterday, I had high battery consumption. So yesterday was a breakthrough but YMMV. I removed the PCSCII and the Mail app (I don't sync with Exchange and I don't sync with a PC as such - I don't run Windows). I also disabled auto task killer. I rebooted without being connected via USB to power or to PC. Suddenly power consumption became similar to Modaco ROMs.
Last night, I also disabled the setCPU application and rebooted. 6% battery consumption in 9 hours. 34% cell standby, 33% WiFi, 33% phone idle. Consumption was 45% in 24 hours.
how have you improved battery usage, ive tried resetting battery stats, draining battery, fully charging, using kimera 1.5 and with no wifi no bluetooth, not using phone in few hours it was down to 63% and in 10mins had dropped to 59%
i had similar battery problems but today i changed radio versions into a different one, now i get almost full signal all the time and battery usage is geatly increased (went down 2% in 4 hours as compared to 10%/hour)
so i suggest finding a radio that give you good reception

63.18.55.06JU_6.35.08.29
made alot of diference
you should ty out diferent radios and find one that gives the best reception, it will be different for different providers and countries

I will use that radio too seeing as I too am on T-Mobile in the UK. When you say to use the link and suggest doing it, I take it you mean the "get to 10% -> get to recovery mode -> wipe battery info -> reboot and drain battery 'til off -> charge while off and the take off charger once charged and switch on..
'cos I tried that and still having problems - am using the new Villain 4.0 beta2, so maybe the radio change in combination to this is what will work - I'll try it tonight when I get home.
immya : many thanks i now hove phone back
flashed radio 63.18.55.06_6.35.05.31
and lost 1% over night
previously on LOST
radio 63.18.55.06JU_6.35.09.26 lost 56% overnight
perhaps issue with 2.1 roms is the latest radio and not latest kernal
BTW using sensehero at moment as was trying 1.5 roms to get better battery, and that didnt work.
some one maybe sticky this info , if anymore find it a saviour. will report back after work, mayeven be able to use data syncing again
I have installed the second 2.1 leak on my eris and my gf as well. I do the airplane trick to fix the % without signal bug, she does as well. And it works. Both are at 0%. However, if we go to see what's using the battery, my cell standby is very low, while hers is very high (up around 70%). I am just wondering why that is. I don't understand why results would differ so drastically under nearly identical situations. With no virtually no use my battery will last nearly 24 hours, while hers will only last about 6. Has anyone seen this, or know a fix?

Long press power/end button. Turn Airplane mode ON. Press the power/end button to put your phone into sleep. Press power/end button to come out of sleep. Turn Airplane mode off.
The cell standby percentage will/should eventually go down to 0%.
Before flashing CM9 to my mopho I had only used the stock rom, on Gingerbread my battery would last for 1.5 or 2 days, but since i updated to ICS it dies whitin 10~ hours of idle...
it usually goes from 100 to 70% overnight (6 hours). Recently I purchased Juice Defender Ultimate hoping it would help fix this issue, well... it did help but id didnt solve it, went from 30% overnight battery drain to 15-20% with airplane mode enabled in JDUltimate.. wich is ALOT from what i've read most users are getting (1-2% overnight, am i right?).
I've wiped my battery stats over and over (even tried the market app method) and nothing has changed.
I installed BetterBatteryStats and Watchdog from market, and both of them and the android battery stats show that "suspend" or phone idle are the cause of my battery dying so fast.
If anyone experienced anything similar and knows a way to fix this I would really appreciate it!!
Ive never seen my Photon go overnight with only a literally 1-2 percentage loss.. Not on stock, Cybiks CM7, or on CM9. but it usually only drains maybe 10 or 15 percent on higher end so nothing major. Talking ~8 hours off charger idle with random text or two and led going nuts blinking all night with data/wifi/bluetooth etc off but NOT in airplane mode. Are you on latest CM9 build? My bet is you have a random app screwing with phone keeping it from entering sleep mode or whatever its called. Check the "Awake" time under the battery settings to see if the awake time is allot higher than the "Screen off".
I have the same problem, no matter what kernel, no matter what cm9 build, still draining too much in idle. I know, others don't have such draining. But I give up and I am back on cm7, where everything seems fine.
I noticed that this happens to me as well. Previously, I fixed this by re-calibrating the battery. Now I was suspecting skype, but it is not causing this. I have noticed that having both GPRS/3G enabled and Wi-Fi drains power very quickly (about 4 times faster than having only one of those switched on). I'm using Photon in Europe in GSM network, so not sure is it the same with CDMA.

during night, "Awake" seems to be up about 50-60% of the time, a lot more than "screen on"
I´ve read that setting your phone to "never turn screen off" shuts down suspend process and battery actually lasts longer, has anybody tried this??
Are you guys logged into Latitude? I signed out of it yesterday and now after 10 hours on battery, although 6 of it was sleeping, I still had 86% left.

I am not sure, but never logged in latitude myself, so I think, no.
And CPU was perfectly sleeping with turned off screen. But still the same draining. And what I know, it has nothing with gsm.
I as well am having the same problem, dropped from 88% to 72% within 20 minutes.
phone idles killing my battery at 50% any fixes?
try wiping battery stats in recovery with a full charge
I've looked through this forum, but the Only thing I have seen are normal battery drain issues. Mine is not.
I'd like to point out that my Galaxy S3 is the 16Gt non-4G unlocked "Nordic" or European version, and I haven't rooted it.
The problem is that whenever I'm out playing Ingress, and it's chilly outside (0 degrees celsius) the battery seems to drain really fast. I thought it was just because Ingress uses both GPS and internet, and that the screen is on all the time.
I use the phone until it shuts down because of battery. Then I'd plug the phone to the charger in the car, wait for 30sec, and after the screen has fully lit up(I have not yet turned it on) the graphic says the battery is over 50%. So then I turn it on, And the battery is @58%. I unplug it and continue playing. The battery drains real fast again. Then it shuts down. I repeat the above process, and after turning it on the battery is @54%.
Also, sometimes during this battery drain, @10% or so, the phone disconnects from the network. It is disconnected until the battery is at about 2%, then it regains the network connection for the short while it is still on.
I have GSAM battery monitor installed, and it drew a nice graph. I couldn't take a screenshot of it because GS3's screenshot taking is a pain in the arse and I just couldnt do it. But the Graph showed the battery draining from 60%->0% in ½h, then it suddenly started from 58% and drained to 0% in another ½h.
Has anyone else had this kind of problem? If so, have you solved it and how?
The phone was 4.1.2 until I updated it to 4.3 recently, and the problem was on both versions.

Replace your battery.
This is clearly not a problem of the battery, as it does retain it's charge. The phone just doesn't know it until it's connected to a charger. Hence magical 1s charge-ups.
My phone is rooted. Recently I am having a lot of battery issues. My battery gets charged up from 30% to 100% in a few seconds and while using without wifi or data connection it suddenly drops by almost 20% . Earlier my phone used to last a day with 3G connection, now even without data connection it won't last a day.
I am attaching screenshots of my battery statistics. Please have a look and advise me what t do in case you have any clue regarding this.

happened with me also, when your phone gets charged to 100%, restart your phone into recovery but dont unplug your phone from chareger, then reboot your phone from recovery, might be your battery stats would change to actual %, it worked for me.

1) charge you battery to 100%
2) let your phone discharge until it shuts down by itself
3) charge the phone with it switched off until you get a green light.
4) remove the battery but do not disconnect the charger(you'll se back led light flashing)
5) after approx. 30sec... Re insert the battery... Now the led will again be red.. Allow it charge until green light appears...
6) now remove the charger and boot the phone...
7)look at battery info... If it is 100% and voltage at 4200mV then your prob. Is solved...
8) remember... In the whole process don't remove the charger and do not boot up the phone..
9) if the prob. Still persists then you will have to buy a new battery..
