Battery issue - new question

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.

Calibrate your battery

We all want the maximum out of our battery and the corresponding indication. Found this thread in Desire forum on calibration of the battery and can be usefull for Wildfire aswell....http://forum.xda-developers.com/showthread.php?t=755903
Just did the full cycle myself.....will report back results.

The wildfire has a really good battery already
No need to calibrate imo. Can last 2+ days for me when I don't abuse the wifi and games.

First feedback.....no noticable difference seen.....What do seem to help is to charge you phone longer even after green light indicates that battery is full.....For me than takes longer to go from 100 to 99.

How do you do this? I'm doing everything, I underclock my phone down to 160-245 Mhz, I turn on my wifi only when I have to, I keep my phone in airplane mode permanently, I constantly run on display turned down to max. And yet I've yet got to witness my phone going over 18h uptime. Do you run a custom ROM or something?

I find the same thing, and have even been thinking of returning it because it can't last longer than 24hrs. I have even restored to stock and hard reset, so no apps added or anything, BT/WIFI off and the battery life still sucks.

Yes I've tried openfire rom and wildpuzzle rom. Battery lasts as I have stated. I also use setcpu to set up profiles when phone screen is off to help it a little

Would also like to add that on the stock rom, the battery lasts long as well but custom rom is better

My phone is a stock. But as you can see, the battery life leaves a lot of room for improvement. How can I increase ir?

Not sure, but after rooting my battery life improved signigficantly, and it also charges fast than before... htc wildifire.

ok so i charged my phone to 100% and left it on my table untouched last night when i got to sleep, left it in my pocket today at uni without using wifi/games, just to check the time, is currently still at 99% with up time of 14hrs so far.
and if you want to maximise your battery life with stock rom, lower brightness, disable auto sync of accounts, disable 3g if you're not using it, try juice defender, i think that might help you guys.

Hmm strange, I have installed it and icon shows normally in application list.

I went through the calibration process and my battery life has increased significantly. Currently I have 5 hours and 12 minutes of uptime with occasional phone calls and some wifi usage - battery is at 99%.

I find that battery life is all about how strong ur signal is.
At home i get a full 3g signal, battery lasts about 30 hours with my syncs on all day, couple of hours of wifi and maybe 30 mins of gaming and about 30mins of phone calls.
When i'm at work and the signal fluctuates i get about 20 hours average.
When i was in a restaurant for a party recently from 7pm to midnight, there was hardly any signal and i used about 60% of the battery in 5 hours!
At the end of the day if the battery lasts for 18hours with all my stuff turned on then i won't complain as the phone does everything you need except make the tea!
I mean what's the point of turning all the smartphone stuff off? Might as well just go and buy a Nokia.

I'm familiar with the calibration thing n it worked well on my hero but since rooting with unrevoked u get no green light when phone is off n also need to pull battery to turn it on again.. so I don't c how I can with this irritating bug! Any solutions?
With data connection off I get bout 48hrs with just calls n txt. Otherwise with light use I get 30 ish tops

My experience with GREAT Galaxy S battery life!

Hello Everyone!
I made this thread hoping I can shed some light to those getting very poor battery life. I was also getting very poor battery life, till I went and exchanged my phone for a new one. If you're getting very poor battery life (even after wiping your phone or installing a clean firmware), there is definitely something wrong with your phone or your battery.
I own a i9000m bought from Wireless Wave. I've unlocked the phone and am now using it on Rogers.
My previous phone, I was draining 25% of my battery to just get through 6 hours of standby while I slept. I had juice defender on and autokiller memory optimizer. I turned off all syncing and didn't even use a live wallpaper. My phone was rooted and also had lagfix (which I soon removed). One thing I do remember doing is not charging to 100% when I first got the phone. I did accidentally let it drain to 0% cause I had to use it right away.
After exchanging for a new phone and charging it to 100% right away, I was getting the following results. I have juice defender and nothing else. I changed my band to be WCDMA only. I even have a live wallpaper on. Last night my phone idled for 9 hours and it only drained 2%! Last night going out, I had a moderate to heavy (fbook, 3g, gps, text, youtube) usage pattern on my phone and it only drained 40% after 6 hours of use.
I don't know what else to say, but I'm letting those with battery problems know that the SGS is capable of great battery life. And if all your optimizing and tweaks aren't doing it, then you may want to consider exchanging for a new phone if you still have warranty.

I have a great battery life too in my device compared too the another smartphone i used in the past and now compared to Ip4 and N8 in this devices the bat drain is much higher. So im positive surprised with
the galaxy battery performance, i only use the push email everything else is turned off, livewallpaper and so on..

My phone came with JM7 firmware. My battery life is just excellent, not needing a recharge before a few days with my use

Running JPM here, with darkyy's raw metal ROM, my battery life went up by at least 40% - %50. I was losing 1% per 5 - 10minutes of usage, now its more upwards of half an hour of usage.

I think the phone has very good battery life if you understand what can cause battery drain and adjust it accordingly.
I am now gettining 5% drain per 24 hours on (almost) standby. This would give me about 20 days of standby which is crazy.
Here is my setup:
UK 16 Gb Galaxy S with Eclair JM6 and Voodoo lagfix
Set network to GSM (2g)
Disable internet usage (with APNDroid)
Disable WIFI, Sync Off, GPS Off (with power widgets)
Just before I go to bed, I run Advanced Task Killer and kill anything that doesn't need to be on memory (inlcuding Advanced Task Killer itself).
Using your phone WILL spend a lot of battery. Browsing the internet on 3g is a battery killer. This means that if you do something on your phone that maintains an active 3g connection, it WILL drain your battery in about 3-6 depending on your 3g coverage.
WIFI is better, but again you are looking at something between 6-12 hours of continuous usage, so make sure you only use it when you need it.
Finally, if you need to have your emails the instance they arrive, go for a blackberry because it has the only way of pushing email without maintaining a constant data connection.
I don't need this so I am extremely happy with my phone and the battery life I can get out of it.
I hope this helps.

Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

JPM Rom with everything except bluetooth turned on my battery lasted 3 days with low usage (skype a few times and some phone calls and a bit of wifi web-browsing.)
Much better than my wife's iPhone 4... Normally charge it every 2 days.
I am very happy with the phone, just a couple of bug fixes and I would really like it if Swype did some level of contextual checking of words to help minimise unnecessary corrections (perhaps they do already, but it is certainly not well implemented/sophisticated enough).

Eclair for both. No Froyo.

what i wish to have is greater control over the phone, more easily.
Some kind of powertop GUI that let you see the power usage per process.
So you could plain uninstall apps installing ****ty services consuming the battery.
Likewise i'd like *real* control over which background services are running. I mean running an auto killer wtf? Horrible design!
I just want to switch off a service and that it doesnt start again 5 min later thank you very much.
Even the task manager is quite bad. You see last started apps but you don't know which one is running right now. And if its running and backgrounded since a while and you started other apps.. it might very well not even show up in the list anymore. Horrible design again.
Saying all that because stock the phone battery is excellent, installing a couple of popular apps kills it..

Sure thing. And thanks. KIES offered an update from JM1 baseband and JM2 build version. We'll see how the new ROM performs in about 3 days. Unfortunately don't have spare time to do that sooner. I suspect there's huge difference within the baseband versions.

hey guys.
i have galaxy s i9000..i also had problem of battery.my battery would hardly last 24hrs...i even switched to gsm only mode n switched off sync.but still had same prob..few days back i installed JPJPA firmware..now its wroking fine.lasts more than 35hrs...n also battery charges quickly

Is it possible that the reading on the phone is wrong? When you say you are getting 24 hours are you letting it run flat.
Alternately is it saying the battery is running low and you recharge before it goes flat?
Just wondering if the meter is simply giving incorrect information.

Been 24 hours since last recharge. Lost 6% so far. Running JP6 Froyo. Rooted. Network Data Off. During this 24 hours, just used Angry birds-30mins and ColorDict 5mins. Haven't installed any unnecessary app.
Had lost 1% on standby after 14hrs with no usage. Thats amazing. Very Happy user.

Also want to tell u guys that GPS with active Data connection and Google Maps running and display on took approx 1% of battery every 3mins.

Impossible using stock battery, this phone draws a minimum of 10% battery per hour the screen is on. Its more likely 15-20% with most peoples phone.
Your battery meter may be inaccurate, for example after flashing once my battery stayed at 100% for hours then suddenly shot down to 20%

I use "Battery Indicator" to check my battery status.
My screen is set to turn off and lock after 30 seconds of idling. So it is quite possible to achieve the standby times listed.

Hi, how long do you have holding time of battery, when you are using wi-fi? (browsing)

Gingerbread EXTREMELY poor battery life!

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%

I use greenpower realy great app I'm running Gingerbread and I'm getting nearly 2days out of my DHD

Cool, looks like a handy program to have!

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.

when you say check your apps what are you using to find out whats running what.
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.

i just switched to 2.3.3 and its fine, try another rom.

i have to say, the juice defender rocks, totally solve my battery problem.

actually, i still dont understand how it works. days before, i keep.complaining the bad battery, it drops 15% after one night. i turned my wifi and 3g off, it didnt work. i opened a thread to complain about this, some friend advise me to use the juice defender which really help a lot. now it use only 3 to 4% for 8 hours standby, which is much much better than before. if u are also troubled by ur battery, give it a shot. it's free from the market.
my set: all enable except for the location.

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.

You do know there's a setting for turning of WiFi when screen is off, right?
Settings - WiFi - Advanced - Wifi Sleep Policy

Unlikely but a factory reset often cures a problem .

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)

Hmm, am I doing something wrong leaving my phone charging overnight? Will that kill my battery?
When do you guys charge the phone if not overnight?

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!
