I know battery issues have been discussed over and over in this forum, but I have a question that I couldn't find the answer to in this forum.
I have an unlocked rogers x10 that's updated to R2BA020 that I'm using on Fido network, the phone is always roaming because I'm on Fido.
I'm thinking this is why my battery life sucks. I tried everything, task killers, juice defender, dim screen, full discharge.
Does the phone use more juice if it's roaming?
Yes, but it doesn't make a very large difference. If you're worried about constantly roaming, take a look at android, which let's you turn off Amsterdam on 3G.

Have you tried spare parts or something similar to check your battery usage? It lets you see what component is using the most battery. Even the Battery Usage option under Settings->About Phone should tell you where your juice is draining.

If he doesn't want to download spare parts, he could just dial *#*#4636#*#* (did I get that right?) in his dialer to get to the same menus.

Greetings,
Yeah will be more wise to check whats actually draining your battery so we will facts in front of us and try to find a solution.
As for roaming i think yes draining more battery, please gove us usage of the phone , activity and how much your battery can hold up.
Also please onform us what home you use.

I'm still having battery life issues as well on my Rogers x10a.
I was at 100% as of 12:00pm and it's now at 87% 5:00pm.
According to the battery info I've used:
Voice Calls - 30% (10m 35s)
Cell Standby - 28%
Phone Idle - 22%
Display - 11%
Android System - 4%
ADW.Launcher - 3%
3G on, WIFI off, BT off
No idea what is draining my battery so much
I'm on Fido as well, though I don't see a roaming icon anywhere.
Are you sure you're roaming?

2.6%/hr with actual use (not sleeping overnight) is not bad at all. a 4inch screen, 3g connected all the time smartphone will not get great battery life if you actually use it. many people talk about how they get a couple of days or more on a single charge but there is no possible way for this to happen unless you are barely touching your phone. the best i can hope for is a full days use as i use my phone all day and evening.
sometimes an app sits in the background and uses lots of juice, so if you want to make sure that is not happening you might want to do a hard reset and not install any apps for a day and see how battery life it. you can add back apps slowly so that you will be able to tell if one is causing your phone to use too much juice.
the other things you can try is not to use widgets that auto update all the time or try locking your phone to 2g for the day, turning screen brightness down to the lowest level when possible. stuff like that will help. since i updated to the r2 generic rom my battery life has been good enough. i could always use more, but i use my phone too much to expect more.
Thanks I use my phone a lot as well but hearing all these awesome battery life stories had me expecting more. Guess I'll live with what I have.

It drives me nuts too but the reality is that we all use our phones differently so while some people are happy getting two days of use by barely using their phone I just can't do that. I rely on my phone for too many different things, so if I can get through one day I am fine. It was a shock for me initially as I was using a blackberry 9700 and it had a very small screen and long battery life

I took my phone off charge 6 hours ago and I have 79% left as I type.
I did a 5 minute phone call, 10 minutes browsing, 2 minute YouTube video and I turned on WiFi for 30 minutes and Bluetooth for 45 minutes.
I checked the settings and it says:
Display 48%
Standby 18
Phone Idle 13%
Voice call 13%
I've been switching options on and off for the last few weeks that I have x10 and the conclusion is => turn of APN when you don't use it and the battery last for 3 days. Only problem I can think of is mail push but you can always check mail every 30min. There is this "APN on/off" widget that makes switching APN on and off pretty easy so there shouldn't be too much problems.
Doesnt make a difference here.. wifi and 3g cane my battery!!

Update:
I removed JuiceDefender, and I installed advanced task killer, and APN on/off widget and the battery life is much better now. I turn data off when I'm not using the phone and I kill tasks about 3-4 times a day. The screen is dimmed to 15%.
As per Android system info:
Up time: 1 days, 3 hours, 1 minutes, 59 seconds
Up time (without sleep): 0 days, 4 hours, 23 minutes, 8 seconds
17 % battery life left
I checked the settings and it says:
Display 40% (time on 2h 33m 58s)
Standby 29%
Phone Idle 22%
Wifi 4%
Android System 3%
Broswer 2%
Quick question for advanced users, I noticed that Android sys info says up time without sleep is just over 4 huors while the phone settings says 2h 33m, any idea which one is more accurate? I'm assuming up time without sleep = time screen is on.
Switch off GPS. I read about it and how it improved batteries. Bloody true. Its great advice.

Time without sleep = time screen is on
IF nothing isn't keeping the phone awake.
The phone setting says 2h 33m because it counts the time that the phone was asleep AND the screen was off.
The real percentage is the one Android sys info gives you.
It is rather normal for the phone to have slightly more awake time that screen on time, as some applications work even when the screen is off (push Gmail, the clock, some widget etc...).
As long as your wake time is not 100%, you're just fine.

Thanks for the info. Good to know that Android sys info is accurate, almost 5 hours of up time is amazing.
my battery is dropping like mad recently, no matter which rom I use, JVK JPG JPK, all the roms that is known for good battery life, with various kind of modems.2G network taskilled everything before sleep, no gallery bug, no background data updates, not connected to wifi BT GPS, battery stat wiped, more than 3 times full cycle charge..I have done everything I could, the battery still drop like mad.I fully charge the device at 12am, took off the charger, the battery is 88% when its 8am..checked the batter use, cell standby 40+%, display 20+, phone idle 20+..no more and when I slide the menu, for nothing, just slide for fun, scroll the app drawer, see the apps flying, it drops another 1%..lol
I had no idea what is happening, maybe the battery is dead? but I checked the batter health it says good..should I buy a new battery or what
p.s.I had only 1-2% drop everynight back in a month time, but now... ... ... Is this some kind of hardware failure or battery's dead?
12% for 8 hrs is NOT that bad. I get around 1.6% drop per hr with Wi-Fi ON and push notifications.
Anyways, See if you have a Time without Signal entry under Cell standby. Keeping a phone in a low/no service area can drain the battery faster.
You should recalibrate the battery after each rom flash. I think there is an App somewhere in the forum which is really easy to use.

Or maybe just general poor reception in your bedroom? When I'm in school (a nice plain concrete building to prevent young software developers from ever finding joy in life) I have 1-2 bars of edge reception and my phone loses with data off around 1.5%/h.
Either that or your battery has lost capacity and you can fix the issue by buying a new one. My bet is on the reception.
nah not possible..I placed the device on the same spot everyday..back in a month time it constantly dropped 1-2% but now 10+%..its not about the signal or reception or what I guess..it may be due to the frequent flashings recently..anyway I just ordered a new battery..see if it works =(

Hold down your power button. Set data network mode to disabled.
I was getting 10-15% battery drain over 8 hrs of stand by with data network mode enabled.
Now with data network mode disabled (when I need it I just switch it on again) I get 1-2% drain for the same time period.

Turn off all networks, including 2G (put your phone in to airplane mode) and leave it overnight. If the battery still drains the same then you can make sure it has nothing to do with 2G/3G/WiFi/BT or GPS.

What is the point in buying a smartphone, if needs turning off everything?
I suppose your custom ROM is a wipe install
10% battery drain overnight seems to be fine. If you use background data and auto sync, keep on Wifi because that will do the job quickly.
Widgets are notorious battery drains, esp weather widgets. Remove all type of widgets from display. Change sync interval for facebook/twitter to 3, 6, 12 hrs etc... from 15min, 30 min.
Check sync interval for apps like Pulse, buzzbox, weather apps
Just a thought.. how about letting your phone completely discharge. When restarted, immediately flash to stock rom, allow that to completely discharge, repeat process several times (3 ideally) then load your custom rom of choice.
If it sounds absurd, I agree. It really does! However just remember, electromagnetic charge carries resonance memory, much like xrays. This old school trick is not often related to modern batteries, but have found it to increase battery life with several Android devices.
The main things are screen brightness and running apps. Your problem sound's quite normal even. Considered a secondary battery?
I think it is fine because if I use wifi (i.e. browsing XDA forum), it use ~8% for HALF an hour.
Anyway why don't just shut it down when you are asleep?

your battery dropped because you on wifi, at least, the thing is, I din even connect to BT wifi GPS, no task running in the background(taskilled before sleep) and it still drops 10+%..jus imagine if I had my wifi on overnight
I keep reading about this new improved battery life with Gingerbread, however I've found the opposite.
By the time I leave off work, my battery is typically at about 84%, that's with no usage all day. Today is the first time at work I've been running Gingerbread, I'm only half way through the day and my battery is already at 69%, if it keeps draining at this rate, it's going to be down to about 30-40% by the time I've left off!
Did you do a factory reset ? It helped me a lot, i'm at 4 days 6 hours with 16% battery remaining.
Also check if you aren't scanning for wifi 24/7.

Have you checked what application is draining the battery?
Google
I had dreadful battery life and discovered that Latitude was polling constantly and also Google Talk.
Make sure you sign out of both and see if it makes a difference.
... and disable "Tell HTC" service, it'll help as well.

Disable? with force close?
Right, I've disabled Tell HTC, signed out of Google Talk and made sure it doesn't sign in automatically. I've also signed out of Latitude.
The top four things listed on the battery usage are:
- Display = 34%
- Wi-Fi = 15%
- Android System = 13%
- Dialer = 13%
All others are pretty much under 10%.
I'd rather avoid doing a factory reset due to the amount of information and length of time it's taken me to get everything set up. However, I made the mistake of thinking that Wifi wouldn't be used if mobile network was on. My plan was that I would then connect straight away to Wifi when I was at home, and when it lost the signal it would switch to my mobile network. Well, this seems to work fine, however obviously as shown above, it's still using a fair bit of battery. I think I'll just start turned Wifi off completely until I'm going to use it.
For enabling/disabling wifi i use https://market.android.com/details?id=com.sas.inappwifitoggle . Long press search key and it gets enabled or disabled.
- Display = 44%
- Wi-Fi = 15%
- Android System = 23%
- Dialer = 23%

Check out this thread about the Dialer issue:
http://forum.xda-developers.com/showthread.php?t=1069251
My battery life hasn't improved either.
With moderate to heavy use I get about 6-7 hours only. My brightness is usually set at 30%
Display - 69%
Dialer - 8%
Cell standby and others - 4% and less
Is this normal?
Could you give us some more information here ? I mean what type of system are you using, Stock, or some type of ROM ?
I'm running LeeDroid's latest ROM, 2.3.3 and have Green Power installed so data gets turned off when my screen is off.
Auto-sync is turned off too.
In regards to mail, twitter syncing I set mine to every 6 - 12 hours.
I have had gingerbread RUU for 1 week now. With Froyo I used to get 15-30 hours depnding on wether I used 3g or Wifi(Wifi more conservative of battery). Since GB update my maximum battery lasts for 12 hours. I have noticed severe battery drain uder WiFi. Previously with 2.2 with the phoned switched off at night with Wifi enabled, the battery would drain approx 7% in 7 hours. Well today I did the same test switched off phone,left wifi enabled and the battery dropped from 90% to 46% in 7 hours which equates to 7% an hour with the screen off!
This is unacceptable! I sent HTC an email to expalin this but all I got was list of ways to reduce battery life such as swich off wifi, move to 2g, switth off live wallpaper etc etc. But all of this is absolutely of no use if the battery is draining at 7% an hour with the screen off. As I mentioned before with 2.2 the wifi drainage was small approx 1% with screen off.
Can someone suggest a solution?
1)Should I contact HTC again?
2)Try a custom ROM?
I havent tried a custom rom yet as the phone has been runnning well minus poor battery but I may have to if a solution cannot be found.

I noticed the same drain as well when I updated, but after a few days of testing I found that the problem was with one of my apps widgets. My guess is that the app is not efficient on gingerbread.
After removing the widget, everything was fine again.
To sum it up, check your apps.

Also how do i know what i can stop without making other things crash on me
for example. i do not use my sense account so can I shut dwn all things to do with sense that are running without risk?
I had the issue with battery life too. Just get the wifi switch on your homepage and turn off if you're not using it. Otherwise it constantly scans and leaches your battery.

What does it shut off? Seems like it has to be something important to work. I want my email in real-time; does it mess with that?
I installed this only a few hours ago. yet to see any significant change. By the looks of it, having it on the default setting will turn data off when your screen is off, but I still get e-mail notifications in my 1hr check intervals even when my phone is sleeping.

The main feature is that it disables data most of the time (2g, 3G or wifi) and only enables it at preset intervals, like 2 minutes every 30 minutes to get your e-mails and stuff.
So basically what you lose is push / real time notifications.
It can also manage the screen brightness and CPU clock more precisely, put the phone in plane mode while you're sleeping (for example you can tell Juice defender to go in plane mode from 23:30 to 6:30 every day, except if you're still using your phone after 23:30 or start using it before 6:30), or activate wifi only when you're in a specific location.
Does anybody have issues receiving MMS picture messages with JD or any other power saving app running?
I had 'Green Power' running yesterday. A few people sent me pics which came through as blank. Stopped the app and asked them to resend and it worked.
Thanks

I tried this app too, but the battery draining when WiFi was enabled was higher than without JuiceDefender. Still trying to get through all the JD settings...
I dont think Juice Defender would work well for me as I use Whats App a lot...
I use it on my ego. One of the best apps i bought
from my phone duh
Is anyone else able to toggle the 2G/3G setting? I've paid for the Ultimate Pack (wish i hadn't now as the Plus pack is supposed to do this) but apparently JD doesn't like my ROM, the Log says: 'ROM is not compatible with AOSP helper (3G control is unavailable) - get CyanogenMod
Out of interest i was on a UK O2 branded phone so i flashed XEU KW7, then rooted, then put back the original KE7 kernel. I wonder if that's the problem?
I was messing with Juice defender, but I found the app called Battery Booster to be much, much more effective. I went from a 12 hour battery, to having between 24 and 28 hours the last 3 charges. Simply amazing, more than doubled my battery life. Using perhaps 1-2% per hour when sleeping.
1-2% per hour when sleeping is not that good, i get 3% in 8 hours when sleeping.
But juice defender does what should be built into the gingerbread and that is, it puts your wifi and 3g to sleep when your screen is off or when you are not using it.
I personaly dont use push notifications so loosing that doesnt bother me, what bothers me is when the phone is in sleep it drains because i have wifi on.
I dont want to be turning wifi on and off all the time, i want it to be automatic, when i go on the web or open an app that uses data it should turn on my wifi.
SO YES JUICE DEFENDER DOES ROCK.
Well, before battery booster it used 5 - 8% per hour sleeping, so I'm pretty darn happy with the results I'm getting now. It used to last me about 12 hours. Now it lasts usually over 24 hours, which is great. That is included with 3-4 hours of screen-on time. Android OS also dropped by 20% after getting battery booster.

no problem at all with push services.
the way juice def works is simple: it geolocalizes ur wifi router, and moving out the area of wifi, jd switches off wifi hardware until u come back home\office. it does the same with other hardware modules not in use.
wot doesnt work: ebuddy or other istant massaging apps while screen is off (I think it's unuseful to use jd with IM-draining batt-apps)

I just installed Battery Booster. Juice Defender didn't do much for me but annoy me.
Now see how this app will hold itself.
Very similar to my finding with ATK (link below). Something happened in Gingerbread with how the OS handles cached apps... to the point where some cached apps stay active and keep your device awake!

Hello Everyone.
There is a battery drain issue in in cell standby and I think I just solved the issue. Let me go back to when I last experienced such an issue. It was when I flashed a ROM for my SGS1 Captivate called Cognition. There was a bug that left wifi not only on but it was active during sleep mode.
http://forum.xda-developers.com/showthread.php?p=12294219
It was later solved by the Dev and the draining went away.
What is different here is that the SGS3 only has this bug when wifi is on. Look at my battery charts when I have wifi on and wifi off. The red area shows the slope with wifi and the blue area shows it without wifi. This is during standby times.
So is this due to the wifi dual banding just taking up more battery? Or is the phone not properly tuning the wifi down in standby? Solving this issue is out of my hands now and I will have to hand this over to someone else.
For now, change your wi-fi sleep policy to shut off when in sleep mode.
EDIT:
So I think i figured out why the wakelocks are happening. Other people have the problem with dynamic IP addresses.

I don't know why these other fanboy war threads are bumping and so popular but a serious problem doesn't even get a response or a second look. Does anyone else have any comments on how we can get this fix? We need Samsung to fix this problem too.
I will make this post for two reasons;
To bump the topic
To say that i would also like this "bug" to be solved

hi slim,
I agree with you here as well. However I've not noticed any battery drain. I've got about 35% left after good full day of use.

I'm experiencing some kind of battery drain too with sgs3, but mine it's not wifi related. I have as first voice in battery stats page Cellular Standby. I mean, it's almost impossible it drains more then the screen!
Anyway, giving a look at your screenshot, I can clearly see some areas you didn't red boxed when wifi was on, screen was off but battery drain was not terrible at all.
How do you explain them?!

Yeah, I mean my battery life is still good, but I know it can be better. Now that I made it turn wifi off when it's asleep the battery life, the slope you can see there in blue, is a lot better. It's not so slanted and draining as quickly.
A lot of other people that complained about bad battery life I noticed the same trend, it's their wi-fi also. If you notice the long blue line on the bottom, that's when wi-fi is active and those extreme slopes have to be caused by wifi. Cell standby shouldn't be draining the battery more than the screen I don't think.
It's either wi-fi, the radio or both.

I don't know, I guess that is when the wifi properly shuts itself off.
When I look at my screen while I'm not doing anything at all I can see the orange arrow on the wifi on, and it stays on even though I'm not using the internet or anything. What can that mean? Is the orange arrow "uploading" or "downloading?"
EDIT: It's downloading. And I set the wifi to shut off if the screen shuts off. The Wifi sometimes shuts off. But right now it refuses to turn off even in sleep! And the orange arrow is lit up!
How do you get the wifi to shut off when the screen shuts off?

It's there in advanced wifi settings.
Did any of you people tried flashing different modems to resolve this?

If you turn off the wifi then wont it just use the normal data connection and so use more battery? I was led to believe that using wifi was less demanding than say 3g.

Yes that is correct, but read my OP and the thread I posted. A wifi bug is the wifi not powering down in sleep mode. It stays on at full power during sleep and drains your phone.

No, some turn off the wifi radio if the phone goes to sleep

I tried a couple of modems, but in vain. Cell Standby is always much too high. Wifi is beyond good and evil.
I would by now also lean towards a bug. Unfortunately I'm not a Android dev. My knowledge ends at developing apps.
I am satisfied with mine
ive noticed smth:
with Droidwall blocking everything -> still wlan sends smth & causes traffic
hows that possible? u guys can experience the same?
under 3g/edge and droidwall everything blocked: no traffic anymore -> everything is ok!
Have any of you guys tried easy battery saver? One of the features is to disable radios when screen is off. I wonder if it is more successful in doing this than the built in setting.
I got the same cell standby problem so I went ahead and flashed Omega ROM, yesterday was my first day full with that ROM and the result was quite good. I ended up with about 45% battery after about 15-16 hours. Well I'm on wifi for like 3-4 hours though.
Drain caused by exchange sync process. Kill this process and see how battery life will change. Sorry for my english.
Curious, which F/W are you on? I was getting oddball WIFI battery drain using an older LE9 insecure kernel to root at first (WIFI would actually shut off and come back on after coming out of idle... even though I had it set to "always on.")
Completely went away after I flashed back the stock LEF kernel that my phone shipped with.
For reference below, no drain issues during idle with WIFI left "always on."
