Hi there,
So I'd my Defy for a little over 2 months now and I have used the mentioned ROMs with it for at least a week each. It first had Eclair, I promptly changed that to a Pays version of Froyo and now i'm using Quarx CM7.
A lot of my friends have this phone and report battery life of over 24h. They do work in places where they can connect their phones to their laptops and car charger, and they are lighter users than me.
But I'm a med student so I get out in the morning around 6 am, unplug my phone and go to the hospital returning home around 8pm. 14h later my phone is already at 33% charge. I keep wifi turned off, 3G off and use my phone to check MedScape(a medical info repository) and e-mail/facebook 6 times a day and listen to music for 4h.
Is that a good battery life? i mean, for a new phone. I imagine that if I let my 3G i won't get to the middle of my afternoon without needing to recharge.
Around the forum I read about people with OVER 48h of battery life, HOW?
thanks in advance.
Also, as I know it will be asked. My signal reception is flawless all through my working environment.
The .sbf you flashed (for the kernel) is apparently a big factor in batterylife, which did you use under cm7 ?
Which version of cm7 are you running?
Also are you using setvsel?
My settings are 300/23, 600/33, 800/43, and i have gotten almost 5 days battery use on a single charge, with
-texting for atleast 48hr time, intervals of short(10min) periods as you would expect
-maybe 20 mins phoning
-wifi on for half the time when i forget it overnight etc(my profile disables wifi on screen off however-good for light, but battery drain if you lock phone a lot)
-Get the following: OSmonitor, Battery monitor widget.
These help to track what apps eat battery, and kill processes with minimal(1%) drain, that if you arent using then you may aswell take all the battery back that you can
What are your display settings? eg auto brightness, renderfx etc
Thanks

I'm using the latest CM7 by quarx 5.1 and for base i'm currently using 3.4.2-177 nordic Blurless.
I wasn't currently using any undervolting settings to make a baseline screening of the phone with CM7 but i'll try yours and install the apps you've mentioned.
i'm using auto-brightness because of the bugs involved in disabling them in CM7 5.1. And haven't messed with renderfx so far.
Ok firstly i have only tested on 4.0, 4.1 and 5.0 so these suggestions are very likely to work but if certain settings are different in 5.1 then they may negatively affect you- just a thought
Undervolting is actually incredible on cm7 and works a charm, its still super responsive and load times are still less than that of any 2.2 i have tested WITH overclock
Start on about 300/600/800, 30/45/50 and go down marginally-different phones may have different yields to this due to apps running, previous cpu stress etc
(Remember to untick 'start on boot')
Also, the medical database you mentioned- does it contain any 3d renders etc?
This may require you to raise the voltage a little to keep it stable for anything you may to run aswell-- all the apps i have tested such as angry birds, 3d racer games work perfectly btw
Ok, there are extra options that allow you to further change the auto brightness inside the CMsettings under >Display>Automatic backlight
You might wish to experiment if you have time (decrease sensor check-times, lower overall brightness etc), however it likely isnt worth pursuing as the new Quarx beta shows brightness fixes in the changelog already, so just wait is my advice if you are short of time
Ooh and renderfx seemed to drain my battery more on any of the n1 settings, however it may be mix/match to get it right
Hum, I've had bad experiences with undervolting in 2.2 but I'll be sure to try it.
As far as medscape goes, it's just text, no image whatsoever it's just a big list with descriptions "acetaminophen - what does it do, how, dosages and stuff" really useful though
will post back when I have more info from the apps you've mentioned. So far I had used watchdog and it hasn't barked at any of my apps
As long as you take it slowly, undervolting is no problem- also try and minimize the amount of useless apps you have, since many of them run in the background by default without a way to exit them, meaning you constantly waste resources on them and thereby limit the amount of UC/V'ing you could acheive.
Ok thats cool, i was just curious as you clearly need/use that app often
Alrighty then, hopefully you can get some better battery life out of it -good luck
i don't actually have that many apps installed
3g watchdog, only on when 3g is.

well, not that I've written it out, they are quite a few.
He probably means you should use something to kill useless apps running in the background. Look for Advanced Task Killer at the market and install it so you can kill apps that are running in the background but that you're not using.
@Behemia 5 days is awesome in my experience, and you are using your device the same way I am
could you please tell us which kernel are you using (savaged Zen maybe?) and which baseband (if you changed it)?
thanks!
im using cm7 with 3.4.3-11 kernel, undervolted to 300/18-600/30-800/45, kill apps with es task manager quite a lot, 3g or wifi is constantly on, and brightness is set to medium (for some reason auto brightness doesnt relly work for me), and i still cant get one day out of it. battery calibration helped a bit though (i recommend that app to everybody having battery life issues!). is that normal?
Report
So, I've done some of the changes proposed. Undervolted to 300/28 600/41 800/47. Installed Battery monitor Widget, OSmonitor left the phone with 3g off and wifi off when not in use(most of the time) and right now I've got 1% of battery left. That's 1d09h30min after unplug.
Below are the times in ms from the applications that I've used according to battery monitor widgets.
sms 814409
facebook 518805
contacts 355178
dialer 212996
gmail 195103
winamp 67868
medscape 2728
And here battery use report according to system
display 21%
phone idle 18%
stanby 17%
voice calls 15%
OS 7%
media 4%
winamp 4%
gmail 3%
facebook 2%
I'm not saying that 33h isn't good. But my use in this time has been way below my average for myself and the way below most of what I see described here. Plus I don't see any bloatware running nor I do see my apps hogging my battery. Facebook and Gmail push notifications are set to occurs over 2h apart.
Any ideas?
Also, as I finish this thread the phone finally vibrates and dies. Let's put it back to charge and look for more ideas.
thanks in advance everyone.
@lionheartpl
which kind of sim card do you own? i mean an old 64k or a brand new 128k? i upgraded mine from 64 to 128 due to a mobile operator change and my battery usage (same mod, same apps, same usage, same baseband) dropped from 2-3% hour usage to 1% in more than 1 hour. So battery usage has dropped a lot...
Running stock UK 2.1 i could get 4 days standby if i was just texting and a few calls. with the stock UK 2.2 undervolted to 300/22 600/32 1000/52 i can get 5 days easily but i cant see the point in it cos you dare not really use it, i would rather drop down to 1 or 2 days and give it some usage.
Hello everyone,
I'm getting a very good perfomance with the barebones froyo 1.5.6, check this behavior at night:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
That's like 2% loss in almost 8 hours!!!
Right now I am using the version 1.5.1 because I was told it has a better perfomance than the 1.5.6. I'll post my results in a few days.
Also, I use my Defy to be connected to windows messenger network all the time. I'm trying a strategy in order to not drain battery so much:

Even i m not getting a good battery life on CM7 RC1 V1, latest Nightly(9th Aug)
using base band switcher as i m from India
i lost around 18 to 20% every night between 12 to 8am.
over with minimum usage i can get 24 hrs thats witout any music and games, call for 30 mins
not sure what to do
some one please help
I can get about 2 days out of a charge. I am using 300/35 700/42 1000/50 and have had no problems. I recommend using battery calibration! A trick that I have learned is to let it charge to 100% do a battery calibration and then leave it plugged in for a while (30 mins). I have my wifi on all the time and run the smartass profile in settings.
good luck!

For the life of me I can't figure out why my battery drains so fast. I'm beginning to think that I have a defunct battery.
Currently running Manhattan IC1.1.1 ROM with kernel Franco #15 and baseband XXKK6.
I swear everytime I turn on my screen I've lost another 1 or 2%. And this can be minutes apart. As the title says, I've had my phones off the charger for barely over an hour and I'm already under 80%, currently, since I took the screenshots I'm actually down to 73%. I don't think my phone will make it to noon.
I'm particularly confused because it doesn't appear there is any one app as the culprit and my phone looks like it can enter deep sleep without issue. Any ideas?

I'm now approaching 4 hours on battery and at 55% battery.
Adroid OS 49% CPU total 35m, keep awake 1h 28m. Screen 32%. Screen time on is only 36m 42s.
CPU Spy (since I reset 2 hours 2 minutes ago) has it at 81% deep sleep, 16% 1200 MHz.
Kernel wakelocks:
PowerManagerService (partial wakelocks) at 13m 5.6%,
wlan_rx_wake with 10m 4.1%,
mipi_link 7m 30s 3.1%,
alarm_rtc 5m 20s 2.2%,
radio-interface 3m 30s 1.5%
This is ****ing ludicrous. How is it possible I'm at almost half battery when I've barely used my phone for 40 minutes??
CPU Spy makes it seem like my phone deep sleeps no problem but the keep awake time of Android OS seems to counter that. So frustrated and confused.
Just having my phone on for 5 minutes to look up these numbers dropped it from 55% to 49%.
download watchdog free in the market.
Check your widgets to see if they are not refreshing frequently. Turn GPS off and sync. Syncing facebook and other apps constantly can drain your battery very fast.
let me know.
I'm willing to bet it's userland stuff.
Reset CPU spy timer, turn screen off, don't touch for like 30 minutes or so. Then look at your CPU spy. Then check deep sleep numbers against any other CPU slots.
If your other CPU slots have high runtimes, then it's probably an app that's doing it. Try to disable some syncs you don't need, repeat the same testing process one app/setting at a time to find a culprit (or culprits).

Thanks, I'll try that and report back. I do have a bunch of widgets - GTasks, Simple Calendar, News & Weather, Word of the Day, Bookmarks, Pandora, Shazam and Spotify. Although I'd think that only GTasks, Simple Calendar, and News & Weather could be the culprits.

In CPU spy, it lists 1200, 1000, 750, deep sleep, etc. That's what I mean.
The idea is, if you leave it alone for 30 minutes most of the activity should reflect deep sleep. Obviously you're going to have apps that run intermittently even when the phone isn't being actively used.
So after 30 minutes of idle, you see (for example) like 10 minutes or activity on slots NOT on deep sleep, you have some things (apps, etc) that's using up the battery. This is just to confirm that you have an app or some sort that does this. Since everyone has different setup, it's impossible to tell you exactly what it exactly is.
Either way, if this is the case after your testing, you'd need to do some investigation.

Got it - I had a suspicion that's what you meant by slots.
It looks like your syncing is causing the bulk of it. I ended up completely disabling Google Talk and it worked wonders for me. That along with stopping all push notifications (such as email) and setting them to as long intervals as I could manage (15 minutes for exchange, 6 hours for craigslist notifier, 3 hours for weather, etc) improved my battery life dramatically.
Not sure what your governor settings are either but keeping them at conservative or franco's new turtle (a fork of conservative) are always a good idea
EDIT: Also turn off auto-brightness if you have it set, I have mine manually at about 20-30% and it's plenty bright for me.
...aaand one more thing. I also turned off the vibrate and sound on touch features for the android UI. It didn't save me a ton of battery life but it helped a bit

Thanks, good tips. I turned off sound and vibrate on touch for sure, that used to be one of my top kernel wakelock offenders.
I wish there was a setting in stock to sync Gmail at specified intervals rather than just push or no push. I know AOKP has this feature but it wasn't enough to keep me off Manhattan.
I was running Franco (set to turtle) up until this afternoon - although syncing may be the culprit I still think Lean kernel is better at battery management - so I switched back.
Ahh auto brightness. I wish there was a way to keep auto brightness on but offset it by something like -20%. I don't know if it's the adjusting of brightness or the over-brightness of auto brightness that causes the drain but I suspect it's the latter. Wish I could just make auto brightness more conservative then I'd have the best of both worlds.
Is anyone draining at 1% per hour in sleep mode & how are you doing it?
I've read some folks draining at less than 1% per hour sleeping. I'd be happy if I can achieve 1% per hour sleeping.
Anyone getting this or better? If so, share with us your secret!
Here's what my phone is like:
LTE version
Kang, milestone 3
Franco 16.2
max 1000, min 350
no undervolt
no solo cpu mod when sleeping
wifi off
gps on
bt on
My best performance is about 1.5% when sleeping. I charged up my phone to 100% and then unplugged it and let it sleep overnight. 7hr:45min later, woke up and it's at 88%.
I did wipe battery stats when switching ROMs, so it's fresh.
I unplugged my phone last night (100% charge) and 8 hours later this morning it was at 94%. So a little under 1% per hour.
Using stock Android 4.0.2 GSM. Wifi was on, Bluetooth off, GPS on, Sync on. Sadly no secrets to share, been pretty happy with the battery life though.
I have stock 4.0.2 and i get even lower numbers than that.. last night i charged it up to 100% and when i woke up (8 hours later) it was down to 96%.
(gsm)
where did you get the franco 16.2?? ^^
I lose about 0.5% per hour in idle. After 8 hours, I have about 96-95% battery left. This is the GSM nexus with the official 2000 mAh extended battery. Not sure if you have GSM or LTE.
Kang, milestone 3
Imoseyon's Leankernel 1.7.4
max 1200, min 350
stock undervolt that is on the kernel
Interactive X governor
wifi off
gps on
bt on
I get around 4 hours of screen on time.
Make sure anything you have syncing is doing it at a moderate level, when I set up my two email accounts they were set to push and sync every 15 minutes, both are way too much for what I need email for so I set them both to an hour.
Also, changed twitter to only manually sync being that it only takes a couple seconds to due and saves the phone from unnecessarily turning on from sleep.
Don't know if this helps but maybe try turning NFC on if you don't use it?
Disable Facebook contact sync as it doesn't work with 4.0 anyways.
If you can, disable bluetooth, same goes with GPS/Location services.
If you have fancy widgets/beautiful widgets, see how often they update location/weather.
Sorry if it seems like every other point here is just checking what is syncing and what not but when your phone is sleeping those are really the only things that will effect battery life.
Edit: Wiping battery stats has been proven to not do... Well anything.

same with me ... using stock 4.0.2 ... drain is about 1% per 2 hours
I drain 1% every 2-3 hours. So after 8 hours i'm at 96% overnight. This phone has superb idle drain. This is with wifi connected, 2 gmail accounts synced, 1 calendar, contacts and picasa, gps is on. But i do not have facebook app installed. I am stock 4.0.1 and dont have many apps installed, only what i use.
mine is great when idle but as soon as I start using it it drops precipitously any ideas or fixes?

Sadly, lower the screen resolution is probably the easiest way that will notch the best gain in battery life. These screens require a lot of power especially at their brightest settings.
Sign out of latitude...
so key to good battery life
I have the GSM Galaxy Nexus running stock 4.0.1 and I consistently lose 4-5% in 6-8 hours overnight with...
- WIFI on
- 3g/4g on
- GPS on
- bluetooth off
- NFC off
- syncing 2 emails, 2 calendars
- lightflow running LED notification for max 2 hour but on silent (not uncommon for a couple of notification go off during the night)
- beautiful widgets with 1 hour sync
- no effort taken to kill facebook or other backgroung apps.
Try out the new 4.0.4. You're standby drain will go down considerably.
OP, are you on a GSM or CDMA Nexus? Are you on 3G only or LTE/3G?

Yep. That's about the same exact thing I get on a day-to-day basis with the same settings you mentioned. In addition, I don't think I've ever turned NFC off. So pretty much everything but Bluetooth stays on for me overnight.

Sounds like you may have a wakelock check your awake time com paired to your screen on time , if its considerably more then you may have some apps waking your device. For me it was Google maps so I disabled it for now till the update. I used betterbatterystas to find the wakelock. Now I get 3.5 hours screen on time and under 1% drain per hour

you guys realized that gps and bluetooth do not drain battery unless you are using them so it doesnt matter if they are on. GPS will only turn on when an app needs a lock and bluetooth wont use power unless its transmitting to another device. im not sure about NFC but i would think it works the same way. as long as you dont have anything syncing or losing reception at night then you should only lose about 5 percent in 7-8 hours. this is the case with most android devices that i've own.
best I have got is 2% loss in 7 hours...

Best tool, use betterbatterystats and reduce wake locks to a minimum
EDIT:wrong screenshot
Yesterday as I started my day, i pulled my GN from its charger (99%) and made my journey to uni. The trip takes about 50 mins. For the past month now Ive been using poweramp and have had no problems. But when i got to class i realised i had like 25% power during my trip and the back of the GN was a bit warm. I closed all programs and the power drain stopped. I was a bit concerned so a few hours later when i tried playing music again on poweramp but nothing drained the power. So maybe it was a freak occurrence?
So I went to bed last night and the phone was fine. something around 80% power. I woke up 5 hours into my sleep to check on my phone (its a bad habit) and went back to sleep for another 2-3 hours. When i woke up i found my phone had discharged a whole lot of power again randomly in that space of a few hours.
So what the hell happened in that time?! All I did was turn the screen on and turned it off. My usage patterns have not changed.
here is an screen shot of my power usage. You can see the first drop of power, thats nothing of concern as i was playing angry birds space before bed. Then you see the straight line as the phone was idle while i was sleeping. The next drop is when I woke up to check my phone and that's when the discharging happens again. Then you see it recovering when i woke up and closed all the background apps in hope that it would stop the power drain..which it did.

Anyone have some ideas as to what is causing this?
Also keep in mind that before the first instance of power drain my phone configuration had not changed a single bit besides a light flow lite update the night before.

Any apps that you updated or installed yesterday? New rom? Did you make any changes to your phone at all since yesterday?

No new apps, but some app updates. I know at least light flow was updated.
this random power discharge is really getting annoying. It happened again today.
A new symptom seems that the video doesnt load on the phone. for example, trying to load youtube or recorded videos saved on my phone.
Originally i thought my 3g was playing up but when it wouldnt load a video i recorded that was a bit unusual. in fact the gallery app froze and crashed.
Did you search the forum and install CPU Spy and Better Battery stats?
Get some data and find out what is causing wakelocks. Your phone has a lot of "wake" time.
See with CPU spy how much it is spending in Deep sleep and with Better Battery stats look what is preventing it from going into that state. If it's an app: simply remove it.
How's your signal service been lately? I get pretty stank reception at work so my gnex gets pretty warm at the top and battery life suffers. I just put it on airplane mode and reset the radio to force it to chill out for awhile

Thanks ill try that. Just installed CPU spy. Is there an alternative to better battery stats? Don't really want to fork out something to debug this.
I originally used OS monitor, and i checked what was running while the abnormal discharge was happening but nothing showed up.
You make a good point about the amount of wake time though. That long stretch where i was sleeping, my phone shouldnt be waking up that much should it? It didnt seem to affect battery life that much.

How's your signal service been lately? I get pretty stank reception at work so my gnex gets pretty warm at the top and battery life suffers. I just put it on airplane mode and reset the radio to force it to chill out for awhile

Reception has been normal (since I'm around the CBD a lot)

Thanks ill try that. Just installed CPU spy. Is there an alternative to better battery stats? Don't really want to fork out something to debug this.
I originally used OS monitor, and i checked what was running while the abnormal discharge was happening but nothing showed up.

Better Battery Stats is the one I use and is recommended here a lot. It gives you insight in the wakelocks from the kernel, as well as from apps. Don't know about the alternatives. It's definately about the wakelocks. Your phone should be in Deep Sleep for 90% or so when you don't touch it (depending on your sync frequency off course).

The only account that is sync'ed is my gmail. The other two listed (twitter and dropbox) is turned off. Are there other options to turn the freq of when the phone syncs?
It's so strange because before these problems came about I had good battery life. ie: 3+hours of screen time.

You usually set it at System Settings, accounts & Synchronisation but some apps allow you to set it within the app... There are apps that allow you to make profiles so that, for instance at night, your device turns off all data. I used to use Juicedefender but that was IMHO more a placebo effect then a real improvement.
I definately think you should install the mentioned apps and after such drain re-appeared analyse what happened.
So after a little bit of troubleshooting I narrowed the problem down to Light Flow Lite.
Last night I went to bed with 100% charge. It discharged normally throughout the night until 4 hours in when I received an email. I woke up about an hour later and saw this so i suspected it was light flow. I cleared the notification and went back to sleep. I woke up about 30 mins later and was sad to see that my fears were confirmed. Battery discharge had settled down and was acting as normal. Just to be 100% sure though, i sent an email to myself to set off a notification and left it for another 30 mins, and as you can guess, the battery started draining excessively again.
Here is the screenshot. First part obviously is when im sleeping. then that dip is the email coming in. That TINY TINY dip upwards is another email coming in a min after I cleared the original email. So the battery drain continues until i wake up and clear it again. This time no more notifications came through and the battery drain settles down.
Again keep in mind that I have used Light Flow Light for 2 months now without problems.
Anyone else experience problems with Light flow or Light Flow light since it was updated on the 20th March?
I have been great with my light flow lite..I had a problem with my own battery when I updated Google chrome.. uninstalling that fixed my problem..

As much as I love my Archos 80 G9, there's one thing that I truly don't love: the battery life. More accurately, the lack of battery life. Archos' web site boasts 7 hours of video playback, 10 hours of internet surfing, and a whopping 36 hours of music playback on a single charge. My experience is quite different, and I'm currently getting about 5 hours of idle time!!! That's right, just unplugging it from the charger and letting it sit there drains the battery in about 5-6 hours. Now I'm not expecting to be able to watch the "Lord of the Rings" trilogy on a single charge, but just being able to get through "Return of the King" would be a nice start!
I do run the tablet on Surdu's custom ROMs (there are just too many root features that I actually use to go back to stock), but I've had this issue since I bought the tablet back in October just running stock. Even running the "stock + root" ROM (no overclock, fancy transitions, etc.) leaves me with a dead battery in 5 hours. I use a custom Launcher (GO HD for Tablets) and a live background, but neither of these should affect battery life while idle. It could very well be background processes, but this being my first Android device I'm uncertain how to proceed and figure out what might be the problem, or even if I need to send it back to Archos for service. Any help would be appreciated!

the live wallpaper may very much have something to do with it. You need to find a battery stats app and find the rogue app that triggers the device to wake up even when in sleep. Have you tried deep sleep? (in ICS > settings > battery > check "deep sleep"
i usually have a very long battery life while on idle see this screenie

I turned off GPS and Bluetooth, and that has dramatically changed the battery drain for the better. I'm still at 68% after 7 hours at idle with about 10-15 minutes of active use. Still not ideal, but much better. I'll keep trying to find any rogue apps and quell any leeches. Lookout Labs' Ad Network Detector is good at figuring out which "free" apps use the more obnoxious ad networks; it helps to get rid of those, as well.
I'm experiencing same issue here - Archos G9 TURBO 250 HDD with latest ICS and it drains batt while off
Have you found cause of this problem?

a)disable GPS (it's enabled by default)
b)turn on Deep Sleep (settings->battery) or
c)use Hibernation instead of locking the screen only (long press Power and select Hibernation)
If device is powered on and deep sleep/hibernation is not activated it uses quite some power all the time.
a) I turned off GPS but no effect
b) Deep Sleep was turned on from begining
c) tried both hibernation and normal locking the screen - no help
This was on ICS, I'm now trying HC and see if this drains my batt too.
I even installed System Panel Task Manager and enabled monitoring but didn't find any app using too much battery only wierd thing was display - on when I didn't use device...
For me, the GPS was definitely the main culprit. I turned Bluetooth back on and my battery life was still vastly improved, even running overclocked. Beyond that, just keep looking for apps that stay running. A lot of "free" games and apps will keep calling home, even if they've never been launched! MIB3 from Gameloft does this as do many others.

I've installed HC 3.2.80 yesterday, full reset of system and storage, charged to 100% and now only 8% of battery left. I have deep sleep mode turned on, gps off, bluetooth off, tablet switched to airplane mode, in battery usage details - 100% of inactivity (14 hrs 20 min) but something ate my battery. Any ideas?
