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) ?
Hello All,
Noticed the following, and was hoping somebody could shed some light on what I'm seeing.
I noticied ~10%/hour battery drain after flashing AOKP M6. Better Battery Stats showed the Exchange Mail Service as being the primary culprit (60.4% on wakelock), and GSam Battery confirmed the exchange service was keeping the phone awake. I have the mail service set to check every 15 minutes. (Tangent - what happened to Sync Scheduling, where you could specify sync frequency based on day and time?)
I used the power saver options in the rom to disable WIFI and 3G radios when the screen turned off, and battery drain plummeted to ~2-3% per hour. Battery stats confirmed the phone was now sleeping normally. However, now mail syncing is using up celular data.
I then modified the power saving settings to keep the wifi on when the screen is off (but still turn off the 3g radio), and to prefer the wifi network for sync data. Power drain increased to ~7% an hour, and battery stats confirmed the phone is no longer sleeping.
To recap:
Nothing tweaked = no sleep, exchange service the culprit
Wifi and 3G radio disabled = sleeps normally
Wifi enabled, 3G disabled = no sleep, exchange service the culprit
Are there any logs or screenshots or anything you guys would like me to provide to back up my observations? Tests occurred over one-hour periods throughout today. No other activity during these tests (phone was kept in my pocket).
So, I'm having problems with battery usage, I believe.
Recently I have noticed a 12% drainage overnight, with everything off (3G and wifi, only cellular line on), so I installed GSam Battery Monitor and run a test.
I turned again everything off (3G, wifi, sync, bluetooth, gps), only 2G cellular line was on.
I charged phone at 100%, and to be sure I kept the charging cable for another 2 hours before unplugging.
This morning, after exactly 6 hours, I lost 10%.
This 10% has been used in the following way:
- telephone 0%
- display 8%
- cellular ljne 60%
- wifi 0%
- wakelocks 4%
- bluetooth 0%
- applications 24%
- other 4%
The apps' 24% (of the 10% battery usage) has been used in the following way
- maps 12%
- kernel 7%
- GSam Batt Mon 4%
- all others well below 0.5%
Not sure if this is a normal drainage.
What I don't understand is why maps shows such a high %. If I go in details for maps I can see the following:
- cpu use 37s
- wakelock duration 11m
- wakelock number 2400
- standby interruptions 488
- magnetic shield 7m
- Wakelock details: LocationReceiverService and others
- Involved processes: *wakelock* com.google.android.maps:LocationFriendService
Is this a normal drainage?
And why is maps working so hard if 3G is off? Also what the hell is this LocationFriendService and how can I stop it?
Thanks
Def not normal. That location service thing may be an app that is constantly trying to find ur location.
Try to find the app 'better battery stats' it will help u see what is causing all the wakelocks.
Do u have the Facebook app? Do u have 4g turned on or off? Gps on or off? From my experience turning data off at nite doesn't really help cuz some apps will constantly try to connect which will drain ur battery more. U want to be on wifi as much as possible as 3g and even more so 4g suck up more juice than wifi (as long as u have a good connection and it's not constantly tryin to search for signal)
There was actually and in depth post on xda a few months ago abt how to get better battery usage. I can't remember where it was, but try to find that.

I am using a similar app and as i wrote the wakelocks caused by the process LocationFriendService comes from google maps.
I do have facebook but location is off.
In any case overnight the phone has all off: 3g, sync, wifi, bluetooth, but yes you are riht, I believe maps keeps on trying.
yes at home I am always on wifi.
My real problem now is how to have the process LocationFriendService stop running in the background
go into your maps settings and turn off location sharing.

This is not enough.To prevent maps autostarts install gemini app manager (requires root) and in maps app turn off all the flags except "on package removed" and
"signed_in_out" and "updated".
This will save your battery and manual start still works.
I have a Verizon G4 that is not getting the great battery life many speak of. I've tried a lot of things...only syncing the bare minimum of stuff (gmail, calendar, contacts), running Lux for auto brightness, used Access lock to turn off most all permissions in most all my apps, disabled/turned off most LG and Verizon bloat, and still I end up getting only 6 to 8 hours before the 15% battery warning, with 30 to 40 minutes screen time (I've been scared to use it more). GSam shows nothing eating up my battery except for Android System, which is typically using 35% to 60%, with all other apps showing minimal usage. My cell signal is strong everywhere I am, as is my WiFi signal.
So, today, on a whim, I decided to turn off WiFi when I got up and unplugged. Now after 8 hours on with 1 hour screen time, I've got 70% battery left and Android System has only used 17%. I consider this GREAT! Ultimately though, I need to get WiFi back on due to data restrictions.
Why would using WiFi be killing my battery? I did notice the day before that, even though I have "Allow WiFi scanning" un-checked, my WiFi screen was showing "searching" every 10 seconds...forever. That seems very battery hog-atious, but I've been told that it's normal (even though it doesn't seem normal to me).
Does anyone know why WiFi is killing my battery or if there is any troubleshooting/testing I can do?
Wifi can be a hog as it is constantly searching for available and open wifi signals. Depending on settings, even while the screen is off it is pinging around looking for open signals. That can kill a battery. In the past, we have had mods to reduce the time between checks from say every 10 second to every minute.
As a rule of thumb I NEVER run wifi unless I am using it. Same with Location or BT for that matter. Hogs always looking for signals.
Disable Wifi Scanning in advanced wifi settings.... I would also turn off google now and limit syncing of google stuff.. I actually have auto-sync off...
A LOT of it can also have to do with the particular Wi-Fi source. At my work, signal is strong, but there's something about it that drains my battery about fifteen percent per hour, even when not in use. And this is across my current g4 as well as my galaxy s4 and s5. Once I get home and connect to my home Wi-Fi, I regularly lose as little as between 0 to 1% over 6 to 7 hours overnight while I sleep. I've started using my laptop (which also uses the work Wi-Fi, but remains plugged in) as an ad hoc Wi-Fi source to which I connect my phone, and that drops my battery drain to about 3% an hour.
Edit* I also leave absolutely everything syncing all the time. Regardless, I lose extraordinarily little (~1% overnight) on home Wi-Fi.
I've got a brand new unlocked Moto Z play with the Offgrid battery mod. This morning I was disappointed to see my wifi, despite being disabled, had nearly drained my battery mod. I have the wifi configured to only maintain a connection while asleep and plugged in. The toggle for background location via wifi is absent from the advanced wifi menu.
Why is my wifi constantly on, despite it being toggled off?
I've attached a screen shot of the battery screen.
Edit: found the wifi scanning toggle in locations. I've just switched that off.

That's strange. Android Marshmallow comes with Doze functionality, and if the user is not using or moving the phone, it cuts down all background app activity that may eventually drain your phone, thus preserving your battery. You'll still receive notification about emails, and messages in social apps, as they're considered priority, if I'm not mistaken.
I'd say the source of your mod losing battery is your cellular reception. By the print you've posted, the Cellular Network Signal bar is most of the time red, orange or yellow. Poor cellular coverage eats up your battery.
I thank you for saving me the trouble of creating this thread, also did turning off the wifi scanning help?
keep wifi during sleep?
Wi-Fi has been switched off most of the day, wifi location scanning is disabled, and wifi connections while asleep are set to never. Still, it's almost ALWAYS on. Even when my ATT connection is strong it's still sucking down my battery. Wi-Fi remains my largest drain. Larger than cell standby, play services, and the screen.
Edit, looking at my images again, it appears my Z Play is treating the battery mod as a charger. Once the main battery drops to 80% and it switches to the mod battery, the wifi never turns off (despite my settings).
I also have similar problem with my moto z play. I haven't used wifi but still showing top ahead of others. Pls help to resolve this issue.
I had a Moto X Play before for a good while. this problem also showed up there (on Marshmallow as well), but I did find out my battery did not actually get drained, it was a reporting error in Android.
I am not sure if that is the case here with you, is the total battery life definitely lower or is it hard to tell?
Battery is still good but it could be better without the wifi drain. Mine is also more than the total energy the screen consumes and I have battery saver on with wifi location scanning off and wifi on only while plugged in. Not sure what would cause this.
Well, this is interesting. Flew to Boston today around 8:30, and as you can see, toggling airplane mode for the relatively short duration of my flight seems to have fixed my wifi drain. Although the phone did reboot in my pocket around 1530. At the time of this screenshot my internal battery is at 80%, and the battery mod is at 55% with only ~2.5 hours screen on time.
Out of curiosity, when you go into settings>location>3 dot menu>scanning, is wifi scanning turned on or off? Not sure about exact menu location as I don't have a Moto Z play, so working off a custom ROM on my Moto E2. Not sure if it would make a difference, but....
Wi-Fi location scanning is disabled.
Interesting, 24 hours after my flight (both legs visible in the chart) I'm showing no more wifi drain. This is with ~3.75 hours SOT. I am disappointed to see the Offgrid mod lost ~30% over night though. I'll still easily get 2 full days out of one charge, but I was hoping for 3-4. Hopefully Nougat's improved doze helps.
I am thinking my phone is also suffering from the same issue. Take look at my other post:
http://forum.xda-developers.com/showpost.php?p=69486349&postcount=77
Mine is even worse. Even when i activate the airplane mode, wifi does not turn off. It is open literally 24 hours. Seems like it drains the battery but I still have 9-10 Hours of SOT, depending on usage this can go up to 13-14 hours.

Didn't work for me, but I stopped caring. I computed total power usage, wifi does not seem to have that portion
Guys, you must confirm if the WiFi actually drains that amount of power. 8/10 times it is a reporting error in Marshmallow, experienced it myself as well. Gsam battery monitor could tell you more.
This solution is for the MotoZ, a similar issue, maybe it could help us a little
