Well, I searched the forums and haven't found anything specifically for the Defy.
Coming from an HTC Wildfire, which under similar usage had a battery drain split of 30% Cell standby, 30% wifi, 30% system, I noticed that with the exact same usage, the Defy has a cell standby use of over 50% every single day (right now its at 54%). Funny thing is, it ALWAYS says on the battery manager that there is no reception for exactly 50% of the time. This is bull, because I live in central London, and I rarely get less than maximum signal displayed.
Also, I'm on WiFi almost all the time, (WiFi at home and at uni, so the only time it uses 3g/HSPA is on the way there and back, which is less than half an hour).
Has anyone else had this? Any idea what may cause it? I feel like I should be getting better battery life than what I'm getting now, it lasts under a day.
Setting your mobile to 2G only should save you a little power, also be careful with task killers as they can kill some system processes that reduce battery usage, restart you cell to get them back.
I can get 3-4days of battery life with lite use.

Thanks for the reply.
I'm not using any task killers, so that shouldn't be a problem.
Any tips on how to switch it to 2G? I can't figure out anything in the network settings.
I'm just thinking that there may be something wrong with my radio receiver/transmitter to be using so much power in comparison to wifi and phone idle (well, compared to my last phone).
You can switch to 2G in wireless & network settings, mobile networks, select network.
But I am already using 2G and I have the same issue, maybe it is a little better than 3G, but still the "cell standby" is using most of the battery.
I saw the battery usage on Galaxy and there is only a very small usage for "cell standby" only about 10%.
i dont know what's going on with your cell,but WIFI is actually the biggest battery taker
,and the strength of signal power really do something to your WIFI chipset battery usage
what about a better WIFI signal....err i tried to change my cell into 2G or even outline
it doesn't work too much as i want
so maybe think about the WIFI problem?
Well, right now the main drainers are as follows:
Mobile standby: 44%
Go Launcher EX: 25%
Wi-Fi: 15%
Display: 15%
Phone idle: 2%
I was in my place all day today, with the phone permanently connected to Wi-Fi, so 3G was not in use. I get very strong cell reception in my place so I either have a spectacularly efficient WiFi module, or a power hungry cell radio. Or the measurements the phone is taking are wrong.
On another note, Go Launcher seems to be taking up a large percentage since its last update (yesterday or the day before), so I'm uninstalling that.
if WIFI should not be the reason and you've uninstalled the update task,i think it should be OK...but what would you do if that doesn't work?
the battery usage of standby was still more than 40 percent,yes?
why dont you download another battery monitor software....?
i'd have a longtime software error in my HTC G3.....it alwaws show me 45percent remaining battery ....
in setting/wireless & network/mobile networks/select network --- it's good to set 2G or 3G do not let automatic because it switches from 3G to 2G if the signal drops. Set 3g and see how it is.
(sorry for english)
mine on automatic in 6 hours battery dropped to 50% in standby, and now it is set to 3g all the time
mine:
Mobile standby: 40%
Display: 22%
Phone idle: 21%
System: 4%
Games, Adw Launcher EX and os: each 3-2%
when in games mine sometimes freezes and i must get out and restart the game???? i dont no why and i dont no if it is ok but ....
Thanks for the input everybody. So all of today I used the phone pretty sparingly at home, and it's been constantly connected to WiFi. Distribution is:
Mobile Standby: 56%
Wi-Fi: 19%
Display: 12%
Phone idle: 9%
Android System 2%
Under Mobile Standby, it still says "Time without a signal: 50%" even though it's definitely had perfect reception all day. I don't know what's causing it to report incorrect numbers :/
Anyway, I switched from auto to 3g auto (I tried 2G, it didn't seem to work properly, Google wouldn't even load).
I guess I'll just ignore it :/
Edit: When not on wifi, it seems to switch between 3g and HSPA quite often. Could this mean something?

just like what <stapuv>says when your cell drops any one of the 3G or HSPA singnal another singnal will be switched...it'll use more power for changing network frequently.....but i dont no if this could be the reason for your situation...hmmmm
From my reading the 50% without signal is just a software bug, and can be fixed by toggling on aeroplane mode turning of teh screen for 20 seconds or so and then turning of aeroplane mod when you notice it's happening. the 50% will soon decrease. I too believe that cell standby is using way to much on my phone (always 45%+) even though im browesing the web facebook or playing games for larger peroids of time and those apps don't even show up on the battery usage display and if they do theya re only 2 percent or less.
I have a question for you guys :
I get
46% mobile standby
43% phone idle
10% voice calls
3% display
is this 43% phone idle all right? Doea it mean that 43% of the battery have beed drained by phone in idle state (so maybe not sleeping?) or it means that from all the time phone was idle (asleep) for 43%?
I guess mobile standby use is about the same on everyones phones. That's what I wanted to find out!

After Go Launcher EX latest update, the battery seems to drain a lot faster during idle/standby. Removed that and standby battery usage is better.
Just thought I'd add my finding on this.
My Defy regularly showed Mobile Standard over 50% - but also time without signal was always double the time that the phone had been switched on. For instance if the phone was switched on since a reboot for 1 hour then mobile standby would show the total time as 2 hours but time without a signal as 1 hour.
I had always been running on a battery saver profile (in froyo I was running the custom battery profile) & after every reboot the mobile standby bug would show.
Yesterday I changed my battery profile to the Performance mode & after several reboots the bug hasn't shown up & now the mobile standby shows the total time correctly & zero minutes without signal. The %age use has dropped to be more in line with wifi at around 32%.
I haven't noticed any difference in battery life so as mentioned in a previous post it does look like some sort of bug.
A percentage is a proportion.
Just because it's higher on the Defy, that doesn't mean the mobile standby is using more power than it does on other handsets, it could just mean everything else is using less.
There's no point comparing your Defy's battery usage to any other handset apart from another Defy.

OK so after a few days of having no issue I rebooted the phone & the "bug" came back today so I guess it wasn't to do with the battery mode as I then put it back into custom battery mode, rebooted the bug went away.
Haven't noticed any difference over the last few days so I'm not going to worry about it.
I have found that DEFY is getting the readings wrong!
Here is how I get this:
1) fully charged the battery
2) started angry birds.
3) ~2 hour later, battery dropped to 60% and usages was as follows:
mobile standby 49%
phone idle 40%
display 4%
angry birds 7%
WTF ?!?! it should be : angry birds ~ 80%
This mettery is tottaly useless!
Personally I couldn't care less what the battery usage breakdown says. In my case 1% battery can standby 1~2 hours or use 3~5 minutes. That's pretty good for me as a charge can last 2 days.
Hi.
Could someone with this "bug" or "battery problems" do a test for me ?
A few hours after you've last charged your phone (or connected to USB) and being sure you haven't rebooted your phone recently (24 hours or so), do the following:
(My phone uses spanish language so the names might be different ...)
Dial *#*#4636#*#*, and choose battery history.
There, choose "CPU Use" and "since last charged".
What are the 4 or 5 main processes appearing in that list, and what's the CPU time they've used (you'll find that by "clicking" on the process' name) ?
I've noticed a sudden decrease in standby battery life on my Note 2. The "Running" tab of the application manager reports no new apps, though (bad facebook update? they're known for this kind of stuff).
Anyway, it would happily spend 8-9 hours in standby while I was sleeping with 7% battery loss. (Bluetooth, 3G, NFC, S-Beam, Power Saver off; Mobile data, WiFi on)
Now, it barely got 1 hour and 47 minutes with the last 5% of juice.
Running non-system stuff:
Viber
Kik
imo
Formspring
Facebook
SwiftKey Flow
Any idea about the sudden change?

Try to use better battrry stats to find out whats the wakelock while in standby time. And use cpu spy to check you devices in full deep sleep while in stand by mode.

Hello guys, im new to xda and this is my first thread so go easy on me,
I Have G4 H815 international version, upgraded from lollypop to mm as soon as lg rolled it out. Few months have passed with exellent battery, no problems at all. And then suddenly a month ago battery drain have started siriusly to impact on battery life, im talking about 1 hour screen on time, over night 20% standby drain while asleep ~7h. This is what i have tried:
-Bought a new battery - same drain
-Factory reset - nothing chaneged.
Note:
~30% Android system
~25% Google Play services
~12% Android OS
And then was Screen
So 2 weeks after, i have tried to delete updates of Google play services (version 8.4.89(2428711-440)) and disable.
Things got worse.
Battery barely charged, and done another factory reset, only installed WhatsApp and Viber, after which battery got about 15% better.
Note:
screen 29%
google play services 12%
Viber 10%
Android System 9%
Cell standby 9%
Android OS 5%
Disabled everything in hidden menu, but nothing still.
If anyone have any suggestions or thoughts feel free answer.
In advance thanks, im sorry for bad grammar, not my mother language and screenshots still dont know how to upload
Do you have GPS, nfc, auto-sync or mobile data always on?
Sent from my LG-H815 using XDA-Developers mobile app
Gps, nfc are always turned off, thogh sync and data are always on as needed. On Gsam was showing GPS was on the whole time even if i turned them off in settings.

If you keep data and sync turned on during the night that must be the source of your battery drain. Those things are the biggest battery suckers. If you changed your carier that could also been the reason for the anormal battery drain because the signal reception could be worse than the one from your previous caries thus sucking more battery. I mean, if the signal is weak you end up losing more battery. If you keep data on while traveling on public transports that also sucks a lot of battery because the signal is constantly changing between 4g and 3g and that sucks balls.
Anyway, you have here several reasons. I don't exactly know the details of your battery history so you should consider my points and see if any fit your problem
I have wifi/bluetooth scanning OFF. What else could it be?

I'm not sure on this one....you have to have an app somewhere that is killing your battery. My phone normally gets almost a day and a half easily. With Wifi and bluetooth constantly on, watching YouTube videos, and even screen sharing to my TV. Go through your Apps and find the culprit that is killing your battery.
go back to stock, watch drain for a couple hours install an app, rinse and repeat until you find the culprit.
Here, personalization service uses the GPS the most, but I don't know all the related Samsung apps that depends on it.
Same problem here, i dont use too much my phone, not gaming, not videos, just social Network and the telephone dont reach the 5 1/2 hrs screen time, most of the time is on standby, the WORST battery of all my phones in years.
Those with battery drain issue, are you guys using the Exynos version? Mine is Exynos and the battery drain is crazy since day one
Try this, it doubled battery life for me, especially since I spend the majority of my time connected to WiFi.
I'm using the Exynos version and not noticing abusive battery drain.
wifi will off mobile

technically, when you connect to WIFI, mobile data will not be used.
Except you turned on the use Mobile Data if Wifi connection or signal is slow/weak option
I had the same problem... Multiple factory resets and setups later, same problem. Was ready to return the phone because System was using WAY more battery than Display and I was averaging 2.5-3 hours SOT to 5% battery. Found someone suggest Bixby problems in another thread, disabled all Bixby related apps and now battery drain is gone, regularly getting 7-8 hours SOT with no problems.
Additional screenshots (first battery screen is before, second is after disabling all Bixby junk)

Bixby doesnt even show up in battery usage. Should I still be concerned. I Bixby voice is disabled but routines and the Bixby homescreen is still enabled.

One interesting thig I see in you first(high use) screen shot is the amount of battery used by adguard, where as in the subsequent image it doesn't even show up.
Because all traffic runs through adguard, battery stats are skewed when running it. It tells you this when you first activate it. I wasn't using it when trying to isolate my battery troubles, but I'm back to using it 24/7 and still get 7-8 hours SOT, so it wasn't the cause.

Bixby Voice Wake-Up was a huge drainer for me. Find it in apps, doesn't show up on battery stats page, but when you pull up app stats, it'll show how much battery it's used since last charge and for me it was crazy high.
This phone has had the best battery life by far of any I've owned. I'm on the US version unlocked straight from Samsung, using on T-Mobile network. Use it all day at work, been at work playing games and making fantasy football moves on my phone all morning for the past 6 hours and am still at 75% (and my battery widget that uses the system algorithm says I still have 14 hours remaining at my current usage level), and I use Always On Display on ALL THE TIME. Has to be related to an app or something. I will say though that I installed sideActions and disabled all the Bixby packages (along with several other Samsung-specific packages) since day 1 using CCSWE App Manager. I'm not a light user, either - I have Nova Launcher, several KWGT dynamic widgets, Tasker, AutoInput, etc...
Do ensure you have battery optimization turned on.

Disabling those Bixby apps helped a bit with my drain.
hi, has anyone experienced the battery drain when the phone is idle?
last night i've left the phone on 20-22% battery and when i woke up - the phone was turned off because the battery reached 0%...
when it charged - the idle battery consumption was off the wall...
device is about a month and a half old...
i'm using stock MIUI (latest, EU), not rooted
phone is slightly debloated via adb fastboot tool...
phone doesn't use 5G network at home or ever, mobile data is turned off when i'm home
i just can't figure out what is happening...
thanks in advance
Debloated too much I think. Have the same issue when I have Samsung Phone and used adb debloater
not sure about that...
i didn't touch any crucial Xiaomi apps, just recommended ones and never had any bebloat battery drain issues on any device which was debloated or even rooted
update:
last night i left the device with 38% battery, just to see what would happen
in the morning, 8 hours after - it still had 35% charge strange...
note: in the meantime, i adjusted some apps not to work in the background if not needed and uninstalled (almost) never used Google Lens (which i've installed few days ago to try something)
didn't touch any battery settings for common social and messaging apps that i use (Facebook, fb messenger, google messages)
so, maybe the culprit was either google lens or some of those adjusted apps - or the device doesn't read the battery well when under 30%... i'll see what will happen in the next few days...
@60nine Settings > Battery > Battery Use (check "Daily battery usage chart")
Look there if you see any app that has consumed much battery.
you seriously think that i don't already know how to check this? (how do you think i've found that the idle was draining the battery?
no suspicious apps there, idle battery consumption was at the top...
Sorry, I overlooked that you have already wrote it is the idle drain and not a specific app
no problem
