I've noticed the Firmware .510 idle Battery usage of the phone is higher than the Firmware .475, specifically the Radio Usage, please check the attached image from Gsam. With .475 I would leave the phone fully charged all night and the next day the battery will still be 100%, with .510 it went down by 5% to 95%, mostly Radio Usage and the phone was idle, so I do not understand.
This might be related to the NIP Wakelock
But 510 is providing another lever of performance! After update
I filling that 475 (and lower) was a beta's.
In my case the biggest power sucker when idle is the kernel, according to gsam. On par with the radio.
DISCLAIMER!!!
I AM NOT A MATHEMATICIAN! nor do I pretend to be clever... just trying to help
Lets do some calculations here.
You have .510 firmware, I have .475 (yeah, I know… Don’t have app to change build prop)
Your .510 firmware
Of the 5% of battery used, 37.4% is from radio. This means 1.87
8h27m=507 minutes
1.87/507=0.003688% OF TOTAL BATTERY USED per MINUTE
My .475 firmware
Of the 31% battery used, 7.8% is from radio. This means 2.418
7hr07m=427 minutes
2.418/427=0.005663% OF TOTAL BATTERY USED per MINUTE
Factors like signal strength would have a far larger factor of variance. I dunno how good your signal/reception is, but for reference mine is full bars.
But assuming environment is equal, my .475 firmware is using 40+% more power than your .510 firmware.
In fact, wifi signal strength also matters, by which point it could render my calculation above totally irrelevant!
Any new apps that got included in update that might send data?
Any new installs since of apps since your memory / recollection with .475?

I realised that in opposite to usual Android devices i got until now, the battery appear to be drain really fast from 100% to 15% then suddenly it take really longer. As for example I run antutu just after unplug my phone and it loose 2% and when the phone was at 14% i didn't lose even 1% then at 1% i did run a full antutu bench and my phone shutted down after 2 minutes of use.
I am on .510, can't make comparison with .475 as I used it for barely 30 minutes, time to download update to .510.

Ha, + 1 with this. At first I thought its because I turned on the low battery mode, but it's not. Draining 1% is the fastest when I'm at 100%.. Just turned the screen on and 1 minute later its 99%..

Weird. I think the latest firmware update has improved battery life significantly. I usually charge my phone at night and unplug before I go to bed and I'm getting 1% - 2% drop over 8 hours of idle time. I have stamina mode (Gmail, Outlook & Whatsapp always on) on and using Wifi at home.

Ive noticed serious battery drain since I first bought this fascinate from telus. On 2.1it lasted around 11 hours. Since upgrading to 2.2 leak, id say 8 hoirs max with only approx 1 hour of uusage and the rest on standby. I turned of sync, auto brightnrss and turned brightndss as.low as possible. I make sure no apps r running in the background. Yet it still dies superfast. Is this a issue with my battery thr phone itself or firmware or kernal. Its been a week of trying to find the problem so any help would b greatly appreciated. At tgis time im running 2.2 leak with all the files it came with and no root. Thx in advNce
And hour and 12 minutes with about 30 min of internwt surfing and im down to 80 percent WTF
I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

sounds about average for a fascinate....
I'm on telus as well and also have terrible battery life, I've found no fix other than completely turning off Data using the toggle when holding the power button. Flashing a new rom might fix this but I've been to scared to since I bricked a phone trying it the first time. Hopefully when/if ever we get a 2.3 update it fixes this
Does anyone know where one can get an extended battery for this? I picked one up but it's for the friggin Verizon US version, and the battery cover isn't compatible, even though the battery fits(camera doesn't align, speaker's not even close).
Seriously, the American counterpart's accessories have been my biggest frustration with this phone, next to battery life...
Thought I'd give this a bump. The battery life on this Telus Fascinate 4G is truly disappointing and jumping through hoops trying to find and kill apps and services with and without utilities is wasting far too much of my time.
Anybody get a good handle on this?
Bump for same problem.
Samsung Fascinate SCH-i500 Verizon
Running unmodified and unrooted. The phone itself works perfect. No problems other than the phone seriously eats battery. Yes the battery is still good and nothing wrong with it. Plugged in it charges super slowly. And the screen itself takes more than it provides. So i did the following.
A. Changed battery to a known working one.
B. Check with car charger and a home charger. As well as official samsung charger.
C. Gave a ROM a try. Running Dirty Unicorn. Lowered cpu to 800 max and 100 min.
D. Turned display to 50% Brightness.
My only try now is to try a different kernel or something. Im also thinking that the display itself is the culprit somehow eating to much voltage.
Or the gpu. The phones operating temps are good.
I have another post here http://forum.xda-developers.com/showthread.php?t=2430393 relating to where i have a USB problem and need help figuring it out. There has not been any replies. So i am taking upon myself to learn more. Ive worked with 3 Droid Milestones. Hopefully these two i500s will not be to hard. I need help on this new i500 to see if its not the motherboard. The charging port is on the motherboard and if this replacement eats batteries , then the point would be mute to use it for a working USB. A conundrum.
Do i try a different kernel or somthing else. Whats my next step.. Please help.

what else do you have running?
what is the battery life overall usage? and screen usage hours?
screen is always gonna be the highest consumer of your battery
50% still pretty high unless you are out in sunlight, I keep mine between 0 and 30 % unless in sunlight
you can try running the greenify app from playstore.
what king of life are you expecting to get? anywhere between 6hrs to 24 hours total phone battery life is about average depending on how heavy user or how much in standby mode.

I had installed the program and it didn't really show anything abnormal. Although after installing the Bat Meter, when i shutdown it killed the phone till i ODIN. So tried on the other phone as well. Same thing. Install it and compared notes. Reboot phone and had to ODIN. So maybe bad app? Well whatever. I didn't see anything unusual. Although I did notice something strange about the phone that's bad with charging. I already eliminated the battery as the problem as well as charger. But the phone that is eating battery faster than it can charge, it gets warmer at idle than the other phone. It charged just super super tiny faster than the battery eats using just idle display on lock-screen. As well this phone also with a fully charged battery will read 100% But after about 21 minutes of poweramp at 33% volume on headphones will read about 52%. Then sitting rest at idle no display from 52% down to about 14% popup around another 5 min. Then completely dead in about 3 minutes. And the phone is pretty warm. Today it was ambient temp of around 87* outside and sitting in shade and it was hot enough that it wasn't comfortable on my cheek for more than 20 seconds. Half the time the temps are normal. Now remember I'm not running overclock and actually under clocked to 800. Ive tried 3 different roms with diff kernels and same. Could it possibly be a bad heat-sink? And the extra heat is killing battery?
[Q] Battery Drain
I recently was given a Fascinate and am having similar problems. I was told the phone had a bad battery, so I ordered a replacement. Once I got the new battery in, I flashed the phone with the Carbon ROM [the phone was unlocked, but running the OTA 2.3.5 I believe]. Everything seemed to be working fine the first week or two, but now there appears to be a serious battery drain or leak after I power the phone down. I can charge the phone to 100%, power it on and use it for a period of time, then power it down with 90% or more battery life, but when I turn the phone back on, the battery will either be really low, or completely dead, where the phone won't respond at all until I plug the charger back in.
I reflashed the phone with an AOKP ROM to see if that'd make a difference, but it didn't. I tried using the first battery and the drain/leak still persists. The commonality between the two roms is the Devil kernel, so I'm going to flash a different ROM with a different kernel to see if that makes a difference. I also installed the app mentioned above to log the battery stats/usage to see if anything stands out there.
Has anyone experienced something similiar - the Fascinate consuming battery life while powered off?
Yeah the power off leak does seem to exist.
Can't remember the cause though.
I've not tried to really confirm,, but try popping the battery out then back in after you have powered off,,, then check after it has sat overnight to see if drain still exist..
Mine i just always leave on a charger overnight.
.
[Q]
Thanks for the reply. I'll try that. I've left the phone on today, just put it to sleep during periods of inactivity, and the battery is currently at 75% with occasional mild use after 8+ hours "on".
[edit 11-29-13]
After almost two weeks of use, I can confirm that if I power the phone down and do nothing else, the battery will continue to drain to 0%. If I power the phone down then remove and replace the battery, it's fine. It's an extra step, but it works. Thanks again.

Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!
I've read at the development section that almost everyone else has better battery efficiency than I've got.
I'm using the stock rom atm which came when I installed .62 firmware with flashtool. [ROM]Generic MT15i (Neo) 4.0.2.A.0.62 (1246-9107) (Android 2.3.4)
I have also rooted it with rootxperia.zip via recovery. And I have installed inteks v15 kernel with fastboot. Just did a overnight test and lost ~50% battery in 10 hours.
I turned wifi off for the nigth, also chose gsm preferred and disabled data. Should i run test in airplane mode also?
Battery usage shows me that Cell standby and Phone idle takes each like 45% out of the battery and display and fancy widgets takes the rest 10%. I have also noticed that in day-use when I actually use my phone, even if my brightness is set to min and I have turned off the Bravia engine, Display takes very big percent out of the battery, is this normal?
Any tips are really appreciated, I have bought a couple of spare batterys (from dealextreme like 6$ each) so I can almost live normal life with them.. Thanks!
You could try removing the calibration data for your battery, if it seems to get empty too quickly.
Having Cell Standby and Phone Idle roughly equal seems correct. Screen taking up a huge portion is mainly thanks to a rather large screen, which needs to be lit.
Actually just before my overnight test I removed batterystats.bin file with BatteryCalibration app I found from market.
Then let it go for a few cycles.
After the 12070 update my Lumia 800 battery life is totally random.
The diagnostics tool is totally useless since the readings vary without any reason. Sometimes the remaning capacity is 1289 mAh, ten minutes later is 976 mAh...
When I finish charging the phone, sometimes battery life expectancy is about 16 hours, 4 hours later it´s 22 hours...
Another strange thing: once, the phone entered battery saving mode...(20% battery left) Fours later it still was on battery saving mode, but showing 36% capacity left

Overall I would say battery life is more or less the same, somewhat better.
Yes, the battery meter is useless. It shows me 1 day 18 hours but wont even last 10 hours and sometimes it would show 18 hours and last more than 10 hours.
I guess the battery is totally dependent on the usage. I have observed the battery last enough on a normal usage. Though my Nokia E71 lasts double the Lumia 800, I guess its doing good enough that most Android phones
np
i got a super battery life now..
im so happy with the update

The battery meter only counts for atm usage and forecast based on that, this why its not accuracy
Am i the only one that suffers from even poorer batterylife after the 12070 firmware ?
Since the update my battery drops to about 15% after 3-4h, and the diagnostic tools shows a Current Discharge ~350mA.
When i just got the phone about 2 weeks ago the batterylife was kinda good took me trough the day and a few hours more, and now its getting worse.
This cant be normal right?

I have the same problem! After update the battery is a disaster

In Mobile network -> Highest connection speed -> change to E.
Strange, but in 3G mode, but significantly lowers the battery life quickly, especially if the stations are like my GSM operator bad 3G coverage in some areas.
So last night i plugged in my z2 to my laptop and download the update 402 via sony pc companion. I left it overnight and this morning when it finished updated, i switched on the phone it was at 99%.
After a few mins i look back, it dropped to 74%!
Has anyone experiencing the same issue? is this normal? is this update bad for the battery?
anyway i did a factory reset, it was still new anyway so not much things on it yet.
ps, i did not lose my X-reality.Its still there
I feel the new Rom takes a bit time to settle.Give it a day or so and then try to troubleshoot.
Sent From My Sony Xperia Z2 D6502 White
Before the update, i got ~6.2 hours SOT per charge.
Now only 4-5 hours.
I'm vastly disappoint son.
Actually one of the things I noticed early on was the biggest battery consumption compared to .55 and .69! I have just remove the device from the charger and with a bit of use, then it goes to 97%!
This is really scaring me! In FW .55 and .69 was very time to see the percentage going down!
See what its like after a weeks use and the battery is properly calibrated.
I bet you will be seeing similar results to the earlier firmware

There is that right?
There is that possibility?
Why older versions did not have this time?
thanks guys for your input. Yeah i think its too early to tell on the battery consumption yet. I will observe it for a week or two and tell again
Most likely when you flash the update, the battery stats reset with other parameters, let it settle for few charges and see if it calibrates.
And check that your phone can enter Deep Sleep (CPU Spy from Play Store or similar). Could be that the update screwed that up.

It would be good to let my battery run out completely and then charge 100% or is not recommended to do this? I know that this type of technology can not do this, but only in this case!
EDIT:
Yesterday I was using the phone and noticed that when the battery reached 60% it took longer to get down the percentage! So I was using the device and the percentage reached 29%, so I put it to charge all night. This morning I noticed a significant improvement, so much that I am using lot and is still at 97%! What leads me to believe that what user said above is true!

It's always like that, any phones after install new ROM(custom or official), it will take couple cycles of recharge to settle down the battery.
Well after 2 days I would say that this firmware drains battery much faster I've gone back to previous firmware version and getting much better battery results so I'll stick with this for now I think
