Desire s batt drain with screen off

Hello fellow users
My gf got herself a desire s today and i installed battery monitor on it and saw that the device have a drain of 14-18ma with screen off
I have a desire hd and got a drain of 3-5ma with my screen off
Is this because i have a custom kernel?
I sometimes have this with my dhd and when i whipe dalvik its cleared again to 3-5ma
Can you guys check how much drain you have with screen off?
Thanks

Haven't had a problem so far with battery life, it's been great actually. Maybe try quiting idle Apps? I am looking forward to a root soon and hopefully a Rom... fingers crossed!

Thabks for the reps.
You have a little lower then my gf.
Gonna ask her how she gets out of apps.
As for closing bsckground apps i believe the gb taskkiller should do that on its own atleast froyo does on my phone so cant imagine they taken it out although its htc

I got drain from 8mA to 22mA in idle wih a Median of ~13mA
WLAN is off during day
GPS is off most of the Time
3 Accouns syncing every 15 minutes
3 Widgets running
Maybe this helps

14mA with WiFi always on and 2 Exchange accounts syncing every 5 minutes plus GMail account syncing constantly.
You might take all background syncing processes under consideration. Also bad wireless reception may cause higher currents.
...number of active widgets, live wallpaper,...

Download an App Killer, they are probably just staying in the background and eating the battery.

since froyo there is a built in app killer so gingerbread also has it and it and therefore using another one will eat extra batt
Xda is full with threads why not to use a app killer

this is what i was curious about. my nexus one gets between 3-5mA of idle current draw during the night with wifi on. but the thunderbolt for example, with the Sense UI ROM, has some weird problem where the current is 34mA idle on stock ROM, and that is what everyone is seeing. i collected 7 days worth of current widget data from TWO units, both identical results.
so is the new desire s something to do related to the new sense UI? or is the thunderbolt just a fluke? 18mA is too high for idle. and especially since the new HTC inspire i've gotten it to 1mA during idle at times, which is mind blowing. so i always attributed that to the new snapdragon efficiency. i was hoping the desire s would be even better, and get superb battery life with 1450mAh battery and normal sized screen at 3.7".
please post more results when you can!

I have no idea what is causing iti have a desire be myself and there are plenty desire s ports out and all give me the drainage I'm used to(3-5 ma) maybe the defs have some tweak to save batt
It could also be the debugging tools that are in a Rom and are disabled in custom roms

Currentwidget and Battery monitor widget logs that the phone use around 20 mA (8 hours log) whit the screen off.
and after 8 hours the battery is drained from 1450 mAh to 1435 mAh.
This is just not possible whit a steady use of 20 mA
1 hour of 20 mA = 20mAh and after 8 hour it needs to be 160mAh

How did you measure it ? Something must be wrong : the battery drainage or the battery use. In the best case you have battery use about 2mA and that's just awesome. If it's not the case you just drained 160mAh as you say it should be. Hope that it's the be first one.

Yeah I just figured it was a typo or mis read his mAh, I can't see any other answer. I would do another over night test and try to confirm.

I did logged whit Currentwidget and Battery monitor widget. And i did calculated the 160 mAh on my own.
The widgets both say that the device use 20 mA messured every 60 sec. After a hour that will be 20 mAh and 8 Hours it will be 160 mAh (8*20mAH=160mAh)
But Battery monitor widget olso did says that my battery is drained from 1450 to 1435 after 8 hours. ( I started whit a full battery)
Last night over 8 hours the device used about 1%=14.5 mAh
2011/04/17|01:27:28|-23mA|68%|3917mV|29.3ºC
2011/04/17|09:27:28|-20mA|67%|3902mV|20.8ºC

I wonder why the desire s gets such high current drain. The original desire, and my nexus one, get 6 mA during idle screen off.

After some days of BatteryMonitor logging I can say, that the current with screen off never drops below 14mA. Often it's even higher (over 30mA).
The Gingerbread on board battery consumption overview shows Maps as a major consumer. Even if I never used the Maps application since the last complete battery charge, it is there as one of the most bat drainers. I have the feeling that it's this behaviour after updating Maps from the shipped 5.2 to the current 5.3.1
But that's OT. The battery drain is too high even without the Maps app.

normal idle screen off should never be higher than 6 mah.....
so what the hell is up with this thing :O ?

i'm experiencing the same issue too

i was experiencing some horrific battery time also, like 30% drain in 7 hours screen off while my iphone only drained 7% in that time. I believe the culprit could possibly be the "use best wifi performance" button coupled with wifi not sleeping.
Ive now turned off "best wifi performance " and set wifi sleep to 15 minutes and im now getting 18-22mA - i understand this is still bad - i cant spot any other apps using battery.
Will update again later today.

All feed back and information appreciated and we all appear in the same boat.
Although I have wifi turned off during the day and still get battery drain

What is your standby drain? I'm looking @ 3.5%/hr.

Mine is more like 7%/hr, which is totally unacceptable, I have all sync turned off, except exchange... with my HD2 running Froyo, I could do 2%/hr with the same settings.... I am still trying to figure out what's draining my battery...
I have also noticed high data usage.. I've tracked it down to T-mobile's AppPack. I've never used the program but it's constantly draining away my data... Is there a way for me to remove the app or disable it?
Thanks!

Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

its funny how some people report 0% battery drain in 9 hours and other get 3-4% drain per hour.....
please post how many charge cycles you went through, its important.
I am personally using HD2 and battery live is amazing. and its only 1250

this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!

Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

Darn it...
Seems like I'm the only person with excessive battery drain...at 7%/hr....
Just wondering, when you go into battery stats and extend the graph, does your phone stay awake when the screen is off?...
Mine seems to be awake all the time even though the screen is off.
I got Watchdog yesterday, I didn't notice any apps with high CPU usage...

Me too.. I lost about 8%/hour in 2g standby mode... Totally unacceptable comparing to my previous galaxy s...
Hope next FW update will improve it ..
Sent from my HTC Sensation Z710e using XDA App

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off

I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.

I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.

how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.

Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.

To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...
Sent from my HTC Sensation Z710e using XDA App

You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.

I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.

CM7 battery life Troubleshooting thread

I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?

I'm running the CM7 w/the 2.5 radio - I'm in a 100% full time 4G area, but seem to have worse battery life when the 4G radio is on, so I just keep the phone on 3G - if I need the faster data I can always turn it on and off.
I'm running the stock kernal, no overclocking or setcpu type stuff going on.
Would like to hear from folks running this ROM w/killer battery life, what are your settings, tweaks, etc. Please specify if you're running an MR1 or Mr2/2.5 version and/or running the latest OTA 2 radio that just came out like yesterday.
I just turned off my FB sync (I forgot about that). I don't have gmail set up to sync automatically either.
I'm going to do this procedure a little later today and see if it helps, this is for the EVO, but, ya know....
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally.
Anybody else try this?
today will be my first full day of work use w/this ROM so we'll see what happens.

Best to keep 4g off if not using it. Also, turn Bluetooth off when not in use.

i had horrible battery life the first day - then it got better. then i flashed mr2 official and battery life is really solid. getting like 15-20 hrs with 4g always on, bluetooth on sometimes. one important thing is having a custom lighting table which i will post later.

I have never, nor do I intend to ever do this. I got an extended battery for a reason. I can go all day and then some on the official roms, and all of the Sense roms.
I am not new to CM7, I have run it on both an Eris, and an Incredible. Both devices got FAR better battery life on CM7.
I am not complaining about this rom, or Slayhers hard work. I simply want to gather information so that we may help him trouble shoot.

This is exactly what I did lol, I had lost 10% in the first 90 minutes, now I am at 58% at 5 hours. I have been streaming google music for 2 hours of that 5 though. I would guess I should have seen an increase in battery usage, but have not.

The battery readings are wrong, I get a full day on 4G with my stock battery and see those numbers for cell standby etc. I use lean kernel though
Sent from my ThunderBolt using XDA Premium App

do you see those numbers for BLUE TOOTH though? We know good and well some numbers are fake, but that does not mean all.
FYI I am now at 37% and 7 hours and 7 minutes... I have not used google music since the last post and I am seeing the exact same battery drain as when I was using it.

I have absolutely horrible battery life when I'm at work (which is basically a bunker). On a normal day, my battery will be dead within 6 hours just sitting there on my desk.
However, when I am at home (great 4G signal), I see my device getting upwards of 16 hours with moderate use.
I will also say that since I upgraded to the most recent radio, I have been having much better battery life at home. Additionally, my phone has stayed much cooler with the most recent RC + new radio combination.

I heard if you change the render fx to n1 calibrated, then you will get like 1 hour extra of battery life. You can change the render fx by going to cyanogenmod settings.

11h32m11s on extended battery 69% left
The other numbers have to be wrong. Theres no way cell standby is the number one battery user.

my cell standby is also showing 30% with the new OTA 2 radio.

I switched to dream kernel (have not wiped battery stats) and am now at 88% after two hours, that puts me at 6% per hour verses yesterdays 10.

only works for AMOLED screens.
edit: to be clear, it only saves battery on AMOLED.

so what i have found is that after installing dream kernel and messing with the governor settings... along with being connected to wifi. my battery life has improved tremendously. i wiped battery stats this morning after a full charge and didnt notice any change.. then i flashed the kernel and messed with gov. settings... after rebooting ive noticed a huge huge difference.. just my 2 cents for anyone who had battery issues like me

Yesterday I was able to choke out 20 hours while in a 4G area the entire time.
Running RC 1.2, Imoseyon's leanKernel extreme mode (extremely undervolted and OCd to 1.4GHz) and using the InteractiveX governor.
Also, I just happened to reboot and surprisingly it only took away 1% of my battery. Amazing considering whenever I did that on a Sense ROM, I'd experience a battery loss ranging from 7%-10%.

What settings did you land on as best?

cpu is set max to 368 mhz(very low) but i can crank it up if im doing somethign like playing games or downloading and want speed. brightness is at about 15-20 percent. the dream kernel and mr2.0 radio have made a big diff too. the dream kernel made the biggest. usually when id power off or reboot id lose 6-10 percent same as someone else i saw post. now i lose maybe 1 percent which is a huuuuge difference considering you lose 10 percent just because you reboot. also i try to stay on wifi wherever i go. on 3g i def notice it drain quicker, but i am no expert and there are a lot of people on here who by far outexperience and outknowledge me(my new 2 words) so im sure other people have some suggestions

[Q] Battery usage Sensation compared to other Android phones

My previous phone has been a Desire HD. Battery usage on this device while the screen was turned off has always been around 1-5 mA
On the Sensation batery usage while the screen is turned off is around 130-200 mA
I've tried various ROMs including stock.
Is everybody experiencing the same battery drain or/and can anyone explain the huge difference between these 2 devices?

the same numbers also here( 130-200 mA) i guess this numbers are not real because in 6-7 hours of standby the battery is emty... anyway htc sensation have the worst battery i ever had...maybe we get some good results with another rom battery friendly

My HTC Sensation's battery drains to 50%-40% in 9hr-10hr - with minimum use. All sync is turned of except weather and exchange account which set up to sync every 2hr - 3hr on weekends. Which is not bad comparing to SGS2, where i experienced terrible battery life 8hr max, but terrible compared to my HTC Incredible S, running with same settings i did see 2 days battery drain on one charge. I will put Sensation on proper test tomorrow, when i start my work.

Thanks for the quick replies
I'm just curious where the difference between 1-5 mA and 130-200 mA comes from?
I understand that the Sensation has a different feature set but this standby usage is outrageous..

Is this mA calculated by an app? It's well known that mA readings on the HTC Sensation with, e.g. Battery Monitor Widget, don't work. It's an archived thread somewhere on XDA forums.
Better way to measure it is this:
Leave your phone on sleep (screen off) for 2 hours or so (make sure the phone is actually in sleep mode!! If you don't know what that means, look for a thread on BetterBatteryStats as that could be your problem).
Then, find out how much of your battery drained at this time (make sure you didn't start the experiment at 100% because % battery is displayed extremely incorrectly between about 100% and 95%).
Finally, divide your battery capacity (1580mAh for stock) by the amount of hours the device was asleep by and then multiply the result by the % battery drained in that time.
E.g. phone asleep for 2 hours, 5% battery drained.
Average mA = (1580/2)*0.05 = 40mA

I dont experience any of the same battery issues... not that i know my mA draw.. but im going to start looking into. I can make my phone last easily a full 24 hour period with average use id say... But i froze all useless clutter apps no carrier or useless apps just what i use. I keep mostly everything off cept data randomly when im on irc/aim etc
Last charge 1d 10h and battery was at 49% :|
33% display
22% wifi
22% cell standby
20% phone idle
3% voice calls
Now didnt use phone very much in that 1d 10h though
found alot of useful information on this thread when it came to freezing apps i know there are a few tools in the development forum that will remove a bunch for you but i didnt like that method since i used some :|

I'll give the method you describe a go
Still strange that this battery seems to drains so much faster then my DHD although it should hold about 300 mAh more.

Why strange? Dhd has only one processor core and smaller screen resolution which should take less power to render, in theory at least.

The screen resolution should not matter in standby/sleep I suppose.
To be clear; I'm only talking about standby/sleep power consumption.
For the dualcore I would expect it to be around 10-20 mA compared to 1-5 mA. Not 130-200 mA..

Battery is atrocious no matter what radio, rom, settings whatever. Stick kernel, custom kernel everything. Straight up **** battery life on those device. Of course tour battery will last longer if you don't use it at all. But who got the sensation to just leave it I'm your pocket?!?

What kind of battery life are you talking about?
E.g. anything over 4-5 hours of screen on time is quite good. On standby anything over 24 hours is very good.

[Q] High battery drain (50-100 mA in current widget in sleep)

I have an unlocked T-Mobile Sensation 4G and I've tried a lot of different rom (with Sense and AOSP, GB and ICS).
I had made battery calibration every rom change (Full charge -> wipe battery stats -> do some full discharge/charge circles in normal use).
Every time I have 50-100 mA battery drain in "sleep" according to Current Widget and another battery widget (tried another to commit that Current Widget tells truth).
The phone settings are maximum power-saving:
Fixed small brightness
2g only
Data and auto-sync are turned off
Wifi only if needed
CPU is downclocked to 1.2 gHz
Battery is stock. Phone is two months old.
In my regular usage (1 hours of calls, 10 min wifi) phone dies in 12 hours after full charge.
It is not my first android and I'm not a total noob. My Desire HD with one year old battery live 2 days with my usage.
Also I notice, that sometimes battery left is not accurate and changed after reboot to a bigger value. For example, 80% left -> reboot -> 82% left.
Any suggestion?
Thanks in advance!
Sorry for my poor English...

My suggestions:
1. Use system tuner or a similar app to check up on which apps are draining the most power (keeping the CPU on, etc).
2. If no culprit can be found, full wipe and reflash your ROM, and refrain from downloading any apps, see if that improves battery drain. If it does, slowly install more apps until the battery drain goes up again, and you'll know whats causing it.
3. If reflashing does not help batter life, you might want to try another ROM or kernel.
4. If none of those help, or even if they do, I highly recommend an ANKER battery, it'll at the very least boost your battery life a few more hours.
5. If the battery life still sucks, then it might be a hardware issue and you might want to get it exchanged or whatnot.
I used to have the same high battery drain problem, but after flashing new ROMS/Kernels and switching to an ANKER Battery, I now get 2 days of light/medium use out of my Sensation.
Currently using Insert Coin 4.5.0 with 1.5GHz overclock+undervolt if you're interested in trying.

Thank you, I will try.

How much does your battery actually drain overnight? Should be around 1% per hour or less if all is well. Disregard currentwidget in deep sleep mode as the Sensation has a very broken meter.

I'll check it this night.
With jumping battery meter I don't know if these values will be correct. But when the battery value reaches 0% the phone shuts down immediately and don't turn on. So 0% it counts well.

i think im also having the same issue . i checked current usage when in sleep mode.its between 50-80

12hrs with the standard battery is actually very good for a sense build, without sense it should go around 15 - if the battery is in good condition. The battery driver for the sensation is very buggy and you won't get accurate results with any measurement app. Don't worry about the standby or inuse readings as they will both be wrong.
If you're battery drains faster than 1% per hour in standby, assuming you are in a good signal area, then use a system info app to see which program isn't sleeping, then uninstall that program.
But it doesn't sound to me like you have a problem.

According to the log file it drains 1-2% in hour (now I'm using aosp build, MIUI). I think, new Anker battery is the only way. Thanks to all!
Maybe in the future we'll get a more accurate battery driver...
