My phone was 100% battery 4 hours ago - now it's 45%
I haven't even hardly used it this morning.
This is ridiculous. Any ideas ?

Maybe sounds silly, but do You have 3G / HSDPA full timeturned on and/or any data eating app(s) running in the background? Usually these drains my I9000 really fast. If I take care to turn stimes 3G off (only 2G allowed) and shutting down the app(s) which run in background make my phone usable for a day.

it's 100% normal to suck so much battery life if you are constantly using 3G or WiFi or long phone calls

I know how to disable HDSPA, but how to disable 3g? :S tnahks

You are using it or something in the background is using it.
Full-on use (gaming) burns about 20% per hour in my experience. Browsing might be a little less but not much because instead of using CPU/GPU power it uses data.
The screen is the major burn, how long does battery usage say the screen has been on?
My battery drain is always pretty much exactly 20%/hour screen time + 1%/hour on time. It will deviate from this if I've played alot of music (especially streaming) since it uses power but not the screen, this drain rate will depend on the player and type of music (built-in player playing from SD card is lean, Tune-in radio streaming over 3G is a hog that heats the phone up, Slacker is in between).

Could be a few reasons for that. If you've recently flashed a new firmware your battery stats may be messed up. Just run down your battery down a few times and it should sort itself out.
Maybe you turned your phone on while it was plugged in. This usually stuffs up the battery stats and can show as much as 30% extra battery when turned on that way. Always remove the charger before booting.
Also, to turn off 3g/hsdpa/data go to settings/wireless & network/network mode and select gsm only (2g). You can also download the widget '2g 3g' which will take you straight there. Also, you can uncheck 'use packet data'. This will kill all data which saves battery. I turn it back on with the widget whenever I need data again. The power button menu also has that option. I'm on 2.2.1 so it may differ if you are on 2.1.
Pretty sure you can still text with data off but may want to test it. If message fails then no. However mms send/receive won't work I think.

i can do 5 to 6 hours straight of 3G browsing with screen on auto before it runs dry
3G + Screen = high power eaters
if i play 3D MMO (pocket craft) then it even less time

I just recently upgraded to 2.2 froyo
i heard there's a battery stats trick, anyone know it ?

there's no battery stats trick . its just a logfile that's stored. nothing else. the trick you're probably talking about is calibration of the battery.
drain fully, charge to full while powered off. one or two charges like this should sort it.

Hey I have a bell i9000 and I have to say that I'm extremely happy with my battery life, I've been unplugged since 9 am, its 7:30 now and my battery indicator is reading 37% with above average use (some phone calls, gaming, browsing...) I would advise you to do these things:
1) install darky's rom (9.2)
2) flash speedmod kernel 13b (very good on the battery)
3) use setcpu and set with these values, max:800mhz, min:100mhz (conservative), and add a profile for screen off with min/max @ 100 mhz and 100 priority level (don't worry, your phone will still feel snappy even @ 800mhz)
4) use a black wallpaper, since black is rendered by turning off pixels on an amoled display.
You should see some improvements, hope it helps!

[Q] WiFi Battery Drain

Alright I hate to ask this question, but my searching and reading is not leading anywhere. I recently upgraded to GB (Illuminance with Corn) and I'm loving how fast my phone is. The only problem I notice is how fast my battery drains while on WiFi (Wireless N with WPA2).
Example: I was at my parents house for 2.5 hours, but didn't bother turning wifi on. I only lost a few %. Once I got home, I kicked on the wifi and within an hour I lost 20%. It appears that when wifi is turned on it is almost constantly in use. I checked for rogue apps and data usage and found nothing. The only thing I notice is that every 5 seconds (yes, I actually timed it) it is polling for new networks.
After doing some reading I checked and the build.prop mods are in there (wifi.supplicant_scan_interval).
Any suggestions on where to go next?
Recap of phone config:
Rom: Illuminance 3.01
Kernel: Corn 7.06
Modem: KK4

Yeah...I've noticed that the build.prop tweaks for wifi scanning don't actually seem to change the scanning interval on gingerbread ;/
Try going to, Settings> wireless and networks> wifi settings> menu button> advanced> set wifi sleep policy to "when the screen turns off"
That'll help while it's asleep.

I switched my ROM from Apex to Illuminance to test a theory that this functionality would work as it had in the past on Apex ROMS. For whatever reason kernels/framework were swapped in a newer version of Apex that killed this very helpful functionality. Once I switched to Illuminance and enabled the functionality, it works again and I get 2+ days worth of battery life with moderate usage (rarely a video/music played, but I do a lot of browsing and email usage/fb/twitter usage is high).
It drove me nuts on Apex trying to figure out the issue. I had thought my settings.db files that control the wifi functions had gone corrupt and the dev ignored any requests for assistance.
Glad I made the switch.

That was the first thing I noticed. The ROM defaulted to Always On. I changed that the first day. Unfortunately, I still have the issue. As it stands, I only get one day at most out of my charge. The only thing I let sync is the gmail account. I mostly browse and talk less than 1 hour per day.
I'll try to do a more statistical approach when I get a chance. I'll see about taking readings ever half hour with the wifi on and no other use.

I was under the impression that if the phone downloads data over WiFi it actually uses less battery than if it downloaded data over 3G. When I'm at home, I leave my WiFi on intentionally when my phone is asleep so that my incoming email is more efficient since I have WiFi available.
Am I wrong here? Just curious if I've been mislead all this time.

I don't think you're wrong. That is why I always use wifi at home. I think I found some errant scripts that were running and causing the excess battery drain. I have taken those off.
I'll probably master clear and reload when I'm no longer on call this weekend just to make sure I got everything.

Power recommendations...

Ok Guys,
Kind of a weird question, but I'm using one of the ICS leak ROMS.
With general usage, 4G/wifi, I would get between 18 to 20 hours, which for me is perfectly fine. The more wifi, the more battery time. No issues at all.
Recently, our office moved where we have a dead zone. I do have full wifi access, however being in this area absolutely kills the battery. I lose 12% every hour. As a precaution, I have disabled the mobile data, and confirmed wifi is working. I have confirmed that I can make and receive calls, and send/recivee txt msgs. However, battery results are the same. Is there anything else I could try?
I'm guessing, being in a deadzone, the phone is putting in overtime trying to find a tower....
Anyone have any ideas?
Thanks in advance...

Interesting... On my Bionic with the .232 leak the option to change network types is grayed out. I was thinking if you set it to 4G or 3G only it would save some battery since the analog radio sure do suck down power (if it even tries to use that as an option).
Not sure what to do. Hopefully somebody can provide something useful.

You can definitely try out a couple of apps from the appstore to change your radio settings in one of the ICS leaks. The first is called "Phone Info" and the second is called "LTE OnOFF - HTC Thunderbolt". See if going with 3g (CDMA auto prl works well for me) only will help your cause.
You could turn the radio completely off, but then you obviously wouldn't get calls, texts, etc.

Ok Guys
Here are my findings...
Looking back, it seems during my move, I also upgraded from Eclipse 2.1 to Liquid ICS around that timeframe. So I back tracked and installed eclipse 2.1 and tested. Here are my findings:
on Liquid ICS 1.5mr:
In deadzone in my office, with wifi turned on, mobile data disabled, I get barely 1 hour per 10%
Everywhere else, 4g/wifi mixed. More wifi, the better, but I get roughly 2.5 hours per 10%
I re-flashed Eclipse, this is what I found
on Eclipse 2.1
In deadzone in my office, with wifi turned on, mobile data disabled, I get approx 2.5 hours per 10%
Everywhere else, 4g/wifi mixed. More wifi, the better, but I get roughly 2 hours per 10%
Overall, the ICS battery usage seems to be much better under normal conditions. In a deadzone, seems to eat away much more battery, even when mobile data is disabled. I'm geussing that its prob checking for a tower much more often then GB?
Any help would greatly be appreciated.....Thanks!

Hey Guys
Just wanted to update you on my findings....
Ok, after playign around, here is what i did. With WIFI turned on, I was getting barely half a bar in the radio signal. For a goof, with WIFI turned on, I went into phone info, and disabled the radio, and re-enabled it. within 2 sec, the radio came up and got half a bar again, but a few sec right after that, I got like 4 or 5 bars. After testing in this state, i get roughly 5 to 6% depletion per hour. WHich is MUCHHHH better.
I have a feeling that with WIFI turned on (mobile data seems to be disabled when in wifi mode), and u turn on the radio, that it connects to a different tower entirely. Because when I walk outside, and disconnect wifi, it goes to 4G, but then u can see it go from 4 to 5 bars, to 3 bars which is normal for me for that area.
Hope this helps someone....but it helped me a great deal.

Battery Drain On s3 i19305

Hi, need some help,
I got this phone a couple of days back, its an unlocked one. Battery on the phone seems to be draining faster than i expected it to. The first time i charged it, it took 3 hours in the afternoon. By night it was 20% this was after playing games and downloading through wifi, so it seemed ok. I then put it for charge overnight. The next day it still seemed to drained by 7pm only used whats app this day, so i had to put for charge again.
Once fully charged (2 hrs) I shut off wifi, bluetooth, nfc and others. Switched off smart stay options and the display is set to lowest brightness (not auto). The wallpapers is also black so it will not drain battery. Overnight without the phone being used (only thing i set was alarm) the charge went from 89% to 78%. During the day I also find the charge still dropping pretty rapidly. I have included the screen shot of the battery from the same day. Between the first pictures there is no difference in use and still drops by 3% in 20 mins or so.
Is this a problem with the battery or is that how it is?
(Stock, no changes to rom)

Not sure if this is your specific problem - but one thing I've found that kills this phone fast is bad 4G cell reception. By default the phone runs as LTE/GSM/WCDMA (Auto) in Settings->Mobile Networks . If you are in a location with patchy (or none at all) 4G Coverage, the phone wastes an inordinate amount of juice switching to high-power mode on the cell radio searching for the elusive 4G/LTE ... Just like a 3G phone will deplete its battery extremly fast in a location with no/poor 3G connectivity (inside the 'secure' datacentres I wander into occasionally that have cell blockers, I can deplete the battery in a phone in about 3 hours just due to it constantly switching to high-power 'cell search' mode as it has no details on any cells to 'hand off' to....)
The difference is palpable... inside my office, if I have the phone on the right side of my desk closest to some windows, it will receive 'patchy' 4G and I'll go through about 60% battery over about 8-10 hours with intermittent phone use (most of the battery goes to screen time as I'm a 'fiddler' whenever I leave my desk for a coffee/break/etc...) If I place it on the left side of my desk, where the reception is much worse, it'll fall back to 3G and I'll go through about 80% battery doing nothing different...
I'm now in the habit of switching the phone to WCDMA Only when I'm going to be working in the bowels of the building, as there aint no hope of 4G there...Doing this drastically improves battery life.. Likewise if I'm stuck at home over the weekend, I leave it on WCDMA, as where I live has very patchy 4G as well and I only get it if I walk outside and down the street...
Just a possible reason for the excessive drain... at least worth trying anyway... *shrug*

Hi thanks for the reply. My phone does not show WCDMA in settings. It just has 2g/3g/4g/ auto OR 3g in network modes under mobile networks.

I have used an app called "Radio Switcher" to activate "gsm auto (prl)", when i open the app it seems to go into "Device info". It seems to work but "Network mode" does not seem to change.

I have uploaded the screenshots

Seems as though the system is using more battery than the screen itself.

The system seems to really take up way too much battery power. Mine is at 4%.
What are your sync settings? Especially for things like Weather, stocks, news etc. If you set them to sync every hour or so, your phone will keep running on the 3G network which will end up draining your battery.
Also, switch off motion. It's a cool feature, but it's not necessary. Same with auto-rotate.
Finally, use WiFi instead of 3G where possible. That saves battery too.
If you're rooted, download noFrills CPU control and reduce your max clock frequency on days where you won't get a charge. Phone runs well enough on 800mhz, but has a tendency to keep going at 1.4Ghz for no reason.
Otherwise, get a higher capacity battery

My sync is off, plus i have disabled sync for everything individuality and disabled all unwanted apps. Data service is also off, only use wi-fi. under motion only smart call is on and auto rotate us off.
I have uploaded a screen shot off after ti disable all these apps.(went to bed with 35% and was 28% in the mornin, turned wifi off before)

Will upgrading (official) phone to android 4.1.2 help (current ver is 4.1.1)? Current base band version is i9305BVALI5 i got an update on kies to i9305BVALI3. I don't think this is update to 4.1.2 is it?

I have updated to 4.1.2, and applied only gsm setting in mobile network. All apps are still disabled as before. The system still seems to be suing most amount of battery, more than the screen. I do not know what is using the system.

I have stared having the same problem a couple of days ago. Though I have sync enabled 0-24 for 3 gmail accounts, motions are on, screen auto rotate is also on. I am using nova launcher, almost all Samsung apps are frozen and most of time I am on wifi.
Now, this drain has nothing to do with the stuff I just mentioned (Enabled sync, motions...). I have all that things enabled all the time, and yes MPU and GPU are OC to 1600 and 640 MHz. But I was always getting >= 24h with ~3,5 h of screen on time. As I already mentioned, problem started a couple of days ago. Only thing which comes to my mind is that I have played with freezing / defrosting apps and I probably installed a couple of apps too. Like Beautiful Widgets and that's my main candidate to blame for this at the moment.
Though I am still not sure... Better than battery stats didn't show anything what could help. Network location locator or similar is at the top of the list of partial wake locks. But the time it hold the lock (About 25 min.) can't be the reason for such a high drain.
I have switched to HD Widgets, what I was using before (With this app one can disable auto location.) removed Beautiful Widgets, and turned off'Use wireless networks' and GPS in location services hoping it will help... So we'll see...

For me it still shows that adroid system and cell standby time is using a lot battery.

I don't get why android system and OS is using so much battery, everything is disabled. Network is on only GSM setting and i have network all the time, why is that also high? Does someone else also have the same problem?

If possible, install Better Battery Stats, maybe it will help you to identify the problem... In my case it is not of much use at the moment.

Strange idea: download an anti-virus and let it run.
Might as well give it a shot now, especially since AV is free.

So any virus should also be wiped out right?

Mobile Radio Active being the main reason of discharge

Hello, I bought my Oneplus 3T recently and I'm using stick ROMwith ElementalX. The main problem I found is that everytime I look at what consumed the highest percentage of my battery are things like WA, Google Play Services, etc. If I click on the to see what is happening, I always get the Mobile Radio Active working like pretty much all the time.
For example, in a normal use for me which is between 26-30 hours until I decide to charge my phone(between 10-20%), I get a SoT of 4 hours and a half more or less. The problem is that from the total percentage of battery used, these applications which have the Mobile Radio Active problem drain between 10-15% of the total amount of battery, while my screen is like 7% of that total value.
Researching on XDA, I couldn't get any solution to this problem. I call this a problem because, every day I see new photos from people with between 7-9 h of SoT in maybe 20 hours of use. Of course, you can't really call this a bad performance of my phone but I think that this difference of hours with screen on is greater than the amount of time my phone stays with my screen off.
As a consequence, I wanted to know if there is a solution or some tips to reduce that Mobile Radio Active bug in order to extend the time between charges.
Thnk you very much.
Additional information: I cleaned flash stock today + ElementalX kernel + SuperSu to see if this kind of bug dissappears.

To "solve" the Mobile Radio Active bug you must take some extreme steps:
First, Root your device. This MUST be SuperSu unfortunately, as the app I'm going to suggest doesn't allow you to toggle the required settings with Magisk or Phh.
Install LeanDroid.
In settings, allow disabling of Wifi, Cellular Data, Bluetooth, Network Location and GPS Location.
Set to "0 min" after screen off. Click "Except".
Configure this screen to your taste, but I have "Except if tethering", "Except if charging (AC). Under Wifi I have "Except if connected to <my home WIFI>" and I have "Except if active: Limit" set to 100KB/s.
Bluetooth "Except if connected"
Location "Except if GPS in use"
and "Network Mode except if original strength OK."
Go back to the main panel.
Restore "After Screen Unlocked"
"Every 60 MIN after screen off" (Configure this to your liking)
With SuperSU and the above, turning the phone screen off disables the data modem when the transfer rate is low, this effectively shuts down the radio and prevents the Mobile Radio Active bug.
Run this with tools like Greenify and ForceDoze to really pump your battery life.
It's not unusual for me to see 8 hour screen on time with these apps and the above configuration.

and without root?

Just curious, how is the status of this bug ? I followed that Bug for like 1.5Years...since Lollipop i think. I myself tryed several things in Sultans ROMs in a OnePlusOne, but no Solution so far ;-(

Bug is still active. As far as I can tell, it remains active in Oero too.
The only option if you are not rooted is to close all apps and toggle airplane mode before you switch the screen off. This only solves the issue until the next time data is accessed by any app, though

THX for reply. Jepp on Wifi i get 4-5days @3-4h SOT. On Mobile only 2 days

Obviously, it takes more power to send/receive signals to a cell tower 10 miles away, versus a WiFi router that is 20 feet away.

Also using WiFi doesn't ensure the modem is Switched off. Modem power doesn't mean data.

This this bugs even remain active in Oreo i will never use android again.

It's existed since Lollipop and I doubt Google will fix it any time soon.

To get 7 hours of on screen time, you will of course have to sacrifice something, the laws of physics are always with us, reminding us from day to day things that can and can't be done. But hey, if you live in a cardboard box next to a cell tower should give you much better battery time without sacrificing the phone-part of your smart device. ? ?
