A friend and I both have a desire, updated to the latest version of Android and running 5.09 radio. Neither of us use it extensively and I can get easily through the day on a charge, mostly having upwards of 30% battery charge left when I go to bed, while his can barely do 8 hours before needing a recharge.
He's already taken it to the store to have it looked at once and it came back performing the same.
I've been looking at his currentwidget log and the consumption seems fine to me, however the battery drain is much larger than I'd expect in return.

Anyone have any idea what's going on? Please help!
Are you two using same ROMs..??
I'm rooted, he's not, but I'm using basically the same thing. My battery usage hasn't changed, while upgrading from 2.1 to 2.2, his hasn't either. But his has been crap from the beginning.
Swap phones for a few days. Perhaps he's in an area where by reception is poor compared to you. The phone would use more power trying to get a better signal?

Does he play games all the time? Does he use GPS, Bluetooth, WLAN? And you?
how does it perform in airplane mode?
Install Android System Info and take a look at the task list, CPU load should hover around 10-20% after a few seconds. If it's higher find the task and report back.
He said if he just leaves it on the shelf with sync disabled, no calls and no notifications, it gets 12 hours tops. I get 48 like that.
Does he use Live Wallpaper? I found out that if I use a plain picture instead of live wallpaper, the power drain is much lower.
Has anyone even looked at the currentwidget log?

Yep, and you're losing battery very fast in what looks to be an idle phone. Every few minutes the power drain is shooting up for a period and then fluctuating to higher than it should be in idle (between 7-70mA drain in idle means the phone isn't idle). Many services and widgets that are known as power hungry seem to be running too. Due to the logging limitations, I can't see if they are the ones causing power fluctuations or otherwise.
I mean, have you done any one hour experimentation with cell on vs. cell off to see the battery loss differences?
What about cell off, display off for an hour vs. cell on, display on for an hour - what are the percentage drops in both cases for the device?

Can't really test like that, since he lives 150kms away. I'll see if he can lend the phone to me for a few days and I'll run both in an as identical manner as I can.
If people like andycted and bemymonkey have much spare time to reply, that would help you much since I consider them more expert in this area (they know far more than me).

Calibrate the battery?
Friend has a new Desire Z (bell, unlocked). Using it on AT&T network.
When at a house, and we use WiFI (30Mbps DL, 25Mbps UL), the speeds are VERY inconsistent. With my iPhone 4 using speedtest.net, it shows up as 20/15 each time. (WiFi is a little slower than the modem).
With the Desire Z, we get 15/10 (which is fine/acceptable). Then 3 minutes later we do it, we get 5/2. Without even moving the phone or touching the modem connection (not downloading anything on the computer), the connection just gets slower. Then it might be fast or slow, basically it's a toss-up.
The first time we noticed the issue is because when we are outside, we get HSPA speeds of 2.5/1.0, then randomly decreases to 0.1/0.05. HUGE difference. And VERY inconsistent. He is using a microSIM from iPhone 4, with an adapter, so we figured maybe the SIM card is getting loose at certain points? However, the WiFi is also inconsistent in addition to the HSPA, so it's probably not that.
What should I do? Is this the situation where I have to flash a new radio or something? (Please suggest others if I am wrong).
Thanks!

Also, his battery is kinda weak. The battery health is apparently clean/healthy. He came from an iPhone 4, where he would have 3G, WiFi, and GPS on at night but not actually using them. Wake up, and 3% battery loss, maybe 5. WITHOUT using them, just having them on.
Now, with the Desire Z, we have the WiFi + 3G on, but NOT the GPS. He is losing 20%-25% in 8 hours without even using the phone.
Information about battery shows a high Cell standby (25%) and Phone idle (25%) percentage. When going into Spare Parts > Partial Wake usage, we didn't find anything really fishy. BUT we had rebooted so perhaps some info may have been lossed. Should he just go to sleep tonight and report the Partial Wake Usage statistics again?
We have a feeling it may be some apps refreshing at night.. But he clears all the apps with Advanced Task Manager except for like Facebook (2 hour interval refresh), GMail, and Google Voice.
I highly doubt a 20% battery decrease overnight is normal.. My mom's Atrix only loses about 5% overnight, with the same parameters I gave before.
I thought it may be a bad battery, BUT the phone idle + cell standby are abnormally high.
Thanks!
Does anyone have an answer? I was wondering this
I have been running CM 6 since November and just recently flashed CM 7. On both ROMs, Cell Standby and Phone Idle have been very high on my list of things that are 'draining' the battery.
For example, today Cell Standby shows as 37% and Phone Idle as 30% for me.
In fact, its very rare that these two things aren't at the top of the list of things that are using the battery for me.... I've seen cell standby as high as 47% before.
I can't speak for the drainage overnight. Definitely doesn't sound normal to me, but my phone is usually on the charger overnight (have enough trouble making it through the day with the stock battery).
Have you tried using Watchdog to monitor CPU usage of apps that run in the background? You could set the notification threshold very low and see what it spits out... Good luck!
gbarayah, thanks for the post, that was helpful.
If anyone can help with the inconsistent data speeds, that'd be very helpful.
And any additional info on the battery would be great too. I recently calibrated it, and will post any additional stats.
Damn it, I forgot to try Watchdog. However, I re-calibrated the battery, let it die, charged it up, let it die, charged it up. I followed the instructions to the letter and all that.
It was at 100% when I went to sleep. Woke up 8 hours later, 74%.
Settings > Battery shows nothing high 40% for cell standby and phone idle. Everything else (Facebook, etc.) REALLY low.
Then I went to Spare Parts > Battery Usage, Partial wake usage, everything incredibly low as well..
I will try Watchdog, but could it just be a bad battery? Or maybe should I try a different ROM?
Thanks!
Not sure if 26% drain over 8 hours is normal or not... Maybe someone else can shed some light on that. My phone is usually on the charger overnight.
The only other thing I can think of that would drain the battery is if you have a bad/weak cell signal in your area. I've experienced that with some job sites where my cell signal is very bad and my battery suffers excessive drain from trying to get a better signal or connect to 3G coming from Edge.
On my week old desire Z running virtuous unity sense3.0 rom and streamlined kernal i very rarely see phone idle and radio burning battery lik you say. Radio occasionaly gets high but only wen in bad coverage areas other than thats its ok.
Battery is still rubbish though due to fact even on 2nd lowest brightness setting screen seems to burn 80%-90% battery
Just checked: phone idle:2%
Cell stanby:8%
Screen (lowest setting):70%
Not this isnt a great example as its taken over a short period of havy use but it still reflects the relative proportion of the battery draining elements in question.
Also a question, if you have a live wallpaper set where is its battery drain shown? Screen, or launcher?
Not sure what to say about the high variable speeds.
Sticking to just GSM(2G) rather than AUTO will in some cases increase the signal and battery life at the expense of slower connection speeds. As mentioned when the phone struggles to get signal the battery gets drained alot faster.
Lower the refresh intervals of all the apps to the maximum period of time or a reasonable amount like 12 hours for FB for Sense, HTC Sense and Weather and 4 hours or Never (to make it on-demand) for Facebook.
Setting the Wi-fi sleep policy to "Never when connected" may make it on-demand too - when an app needs to update Wi-fi gets turned on again
If they have "Use wireless networks" checked to allow the clock-weathers mini-widget to update then they should try removing said clock and re-adding it, but search for the city when doing so. It'll provide them with a general outlook for their entire city and not force it to download and update the information for wherever they are whilst out and about. E.g if you were in London and went from Westminster to Peckham, it may update as you pass through each borough.
Live wallpapers and masses of widgets that need to constantly update are nice and everything but they can also drain the battery.
Think of these suggestions as ways to cycle the battery as well as save it.
I can't think of anything else to add.
I'm using Cyanogenmod 7 and it's pretty damn good. What do you think is the best ROM with Gingerbread if it's more lightweight and easier on the battery? (I honestly don't think the ROM accounts for the 25% battery loss but we'll see)
MIUI or mexiDroid for me?
By the way, could it just be a bad battery? I was thinking about picking one of these up:
http://forum.xda-developers.com/showthread.php?t=940263
$8 and people said it's okay.. What do you think?
Thanks, and I JUST calibrated recently, so once again I will leave phone off overnight and report.
-----------------------
As for the network issues, I FIGURED IT OUT!!!
I believe it was the Speedtest app itself that was messed up. Like I said earlier, I don't have live wallpapers (just info) on, and also NO GPS unless using Navigation.
Well, Speedtest was connecting to WICHITA, KANSAS. I AM IN NEW JERSEY. WTH??!!
Anyway, so I'm going to keep GPS (satellites) on, it connects to NJ, and Voila, GREAT SPEEDS!
HSPA about 3.5/1.0 DL/UL
HOORAY! Network problem fixed!!!
Only issue is battery still D:
Honestly, I think it may be a bad battery. Partial wake usage doesn't show any app going nuts.. Every refresh interval is like 4 hours. And I use Advanced Task Killer to kill all apps before going to bed. I downloaded "Watchdog," let's see

WiFi will always be slower than wired connection, probably about 50% if not more.
Also, what setting do you have your display on and how much would you say you use your phone/have the screen on and how often do you talk (hrs/day)

I have auto brightness but I stay in office and not turn it on much (have to work though ) so the display isn't on much (when i said HIGHEST, it means highest in the list )
I have to phone connected to wifi all day but rarely use it
Mainly use the phone to text and talk less and 1/hr/day
Just try left the phone unused (stand by - airplane mode) for one day, drop about 20% or so
Its seems like its getting a little better.. only lost 10% overnight. Guess its calibrating

Hello,
I want to know if my experience is common or not. I had my phone at ~90% and changed it to airplane mode to try and conserve battery while I went snowboarding. Got back to the phone about 7 hours later and it was dead. Plugged it in and turned it on and found out that "NFC Service" took up 80% of my battery for those 5 hours. When I turn NFC off this does not show in the battery log, but I don't want a major potential feature of this phone to be unusable. Anyone else experience NFC destroying their battery?
Thanks.
I am noticing my Galaxy Nexus not lasting as much as my Rezound did, but it had a larger extended battery. I also use Ultimate Juice to enable / disable my internet connection. So with my extended battery + ultimate juice + brightness on 30% or so I still have 29% battery after a full 25 hours. I would just disable NFC because I do not see it in my battery usage. It is only useful for Google Wallet, and wireless charging (correct me if im wrong).
I use the NFC quite frequently during the day by having various profiles set up around my house, and my battery seems to be fine. Are you using a custom rom or kernel? If the NFC battery issues always occur, I would try reflashing your Nexus. Seeing as NFC itself doesn't eat a significant amount of power, I would guess that the Android OS is being kept awake by the process.

Well I got annoyed and was one day from the end of my return window so I went to Verizon and told them I wanted another phone. They gave in and I just got the new one. Hoping the phone was the problem. I was unrooted with 4.0.2 installed. I don't have a huge need for NFC, but I don't like to think a feature of the phone was completely useless to me when I have seen others who leave it on with no ill effects.
Thanks
Hey guys,
after dropping my beloved Nexus 4 to the concrete floor in May, I bought a new S4 mini in the electronic market because of it's decent size and all the fuzz about having a very good price-performance-ratio.
After a few weeks I already was fairly disappointed.
On an average work day (without WiFi) and little use (~30min OSD) the battery wouldn't last a full day. I tried the usual things like turning off GPS, bluetooth and using Wifi whenever possible (turning it off, when not in range), etc. I also used the App greenify which boosted my deepsleep in Wakelock Detector to stable 85+%.
When using GMaps/navigation my phone is getting hot (~50°C) and battery is drained within minutes. When trying to navigate out of the city (<15min navigation) one day my phone was discharged within 3 hours after a full charge. I got Wakelock Detector, Better Battery Stats and Battery Monitor Widget installed.
The only thing I found out, that when I am connected to Wifi the drain is a lot lower 1-2%/hour compared to when I am using 3G/H+ which results in 7-15%/hour (both when not using the phone), although there is no problem with signal quality. Recently my phone started to bottoming out rly hard when hitting the 20% mark. From there I can watch the battery dropping to 0% within a few minutes.
Things I tried so far:
- turning off features that are not in use (GPS, bluetooth, Wifi when not in range)
- make sure phone gets into deep sleep/greenify apps
- recalibrate akku
- reduce brightness & disable auto-brightness
Setup:
GT-I9195 bought in May 2015 from electronic market chain
CM 12.1 (Android 5.1.1, serranoltexx)
Standard CM Kernel
Baseband I9195XXUBML4
I can provide Screenshots from BMW, WD and BBS. Any ideas how to solve this or what else I could do?
Probably you should use something like better battery stats, to check
- if a service is going mad, then turn it off with disable service to test (most times happens with unclean flash)
- if you have an app with wakelocks
If you can't find anything that way, might be a hardware fault.
Personally if I came across this problem I would return the phone to stock Android and do some tests, see if the same happens again. CM12.1 can have issues across different same model phones. Try the Samsung Phone Info app to see how old your phone is. I'm guessing it was second hand? Some older revisions of the Mini had battery problems. Maybe a new battery is needed? Maybe.. As for the battery draining 20%-0% in minutes I have also suffered this on a brand new March 2015 device. Not all the time though it only happens with randomly once a week. But I put that down to the battery not been fully calibrated and then drained and recharged over the next 3 4 days, as I use a spare battery and swap out the batteries regularly which means my battery is very rarely calibrated.
All that said though I can easily get through an entire day if not 2. And using stock I'm able to get 4 and a half hours on average every time, maybe 4 hours of screen on time when using 3G a lot and GPS etc.

I have had the same problem as you.
I return twice my phone to vendor. But they could do anything.
I solved it with undervolting and underclocking my phone (only the low frequency).
I read from someone, you can undervolting 150 millivolt.
My experience, is undervolting 125 milivolt. and underclocking the low frequency at the minimum.
You didn't feel any difference, behalves that the phone is cooler and battery live is better.
My WiFi and Bluetooth are always on. I don't have to recharge my phone during the day.
It is so effective en transparent that I don't understand why Samsung didn't do it natively.
Hey,
I tried to apply some of your advice and flashed the newest stock rom for S4 Mini (Kitkat ...COE4).
In that process I recognized that the Baseband is not updated by CM and that the one that was installed when I bought it was fairly old (from 2013). Do you think that this might be part of the problem? (I sort of hate the Samsung Rom)
This week when working and not having Wifi all day, I managed to get 2h of SOT and still had around 25% left which I couldnt have gotten before imo. I only lose 1-4% per hour when the phone is not used. But still thats not pretty good, when ur saying you can get 4h with GPS and everything. I also didnt use GPS. And today when I restarted my phone it just went from 40-ish % to 15% without any reason. Any more ideas?
I installed BetterBatteryStats today and will try to give some more insight the next days. Wakelock detector said that I had 85% deep sleep (timeframe 1 day 2 hours).
Try the Samsung Phone Info app to see how old your phone is. I'm guessing it was second hand? Some older revisions of the Mini had battery problems. Maybe a new battery is needed?

No I bought it new from a electronic store (Media Markt). The app says that is was made on Oct 19th 2014 in Vietnam and that it is original/not refurbished.
How much do you gain by undervolting (SOT or % per hour when idle)?
How do you do it?
maybe the best way is to downgrade by flashing CM11 for example ...
(another way with stock + Alexax kernel + own debloat&freeze ... )
I have the same consumption problem with Resurection Remix LP too ..... very strange !
Lollipop is supposed to be less angry than Android 4.X.X ... but it seem have problem somewhere for our S4-mini sources maybe ,i don't know ...
This night I did some BBS tests:
Setup:
Stock Rom I previously installed (see posts above)
charged phone during evening
set up custom timepoint before I went to sleep
WLAN disabled
all apps greenyfied except those I deemed significant that they keep running (Whatsapp, calendar, Swiftkey, BBS, BMW, etc). Forgot newly installed app hoomn.
I had to upload the logfile to pastebin because it was too long for the xda forum: pastebin.ca/3256568 (I am not allowed to post URLs, sorry)
I lost 14% of battery during 9hrs (-1,6%/h). That's probably not too bad?
93% deep sleep, 33min awake time
Weird things I discovered/things I did not understand:
- negative Voltage loss?
- Wifi runtime 100% although I disabled it
- dominant wakelocks (count > 100, all of them < 30s): Alarm Manager, RILJ1, *net_scheduler*, GCM_CONN, ContextManagerWakeLock, Event Log Service, AlarmManager (com.sec.spp.push.Samsung Push Service), SyncLoopWakeLock, GCM_HB_ALARM
- dominant KWLs (count > 100): ril-fd (25min), bam_dmux_wakelock (13min), radio-interface (7min), PowerManagerService.WakeLocks (3min), mmc1_detect (1min), alarm_rtc, alarm, sec-charger-monitor, smdcntl0, pm8921_soc_lock, power-supply, KeyEvents, smsm_snapshot, qmuxd_port_wl_0, qmuxd_port_wl_1, smdcntl1, mmc0_detect
- Alarms (>20): ccc71.bmw (Battery Monitor Widget), android, com.google.android.gms, com.sec.spp.push
any ideas/assessments?
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Google Pixel's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
First night dropped 12% in 6 hours. Not impressed. But I gotta break in that battery.
Sent from my Pixel using XDA-Developers mobile app
I've been losing around 3 % to standby drain over my typical heavy 9 hour sleep (Rx induced)!
I've had mine since last Tuesday.
5" Pixel version.
Battery doesn't seem to go down unless I really get on device for a couple minutes.
Wheee!
Sent from my sailfish using XDA Labs
Last night my pixel went down 2% over about 7.5 hrs so the standby time is pretty good.
My Pixel actually dozed for it's first night. We'll have to see if it keeps going. My N5x gave up dozing a long time ago.
The doze mode has been great for me so far. Standby time is better than any other android phone I've used.
From my other reply:
Battery has been pretty good for me so far. Seems to be settling in with optimization after a few days. Dropped 0% overnight last night which is awesome.
GSAM Monitor is saying my average is 19 hrs on, 4.5 hours of screen on time usage, 1-2 hours of screen off usage like phone calls, music.
EDIT: I also have pretty crappy signal at work.
Stand by time hasn't been a real problem for awhile. My Nexus 5 on KitKat and Lollipop(both before Doze) and only a 2,300mAh would only drop 2-3% over 8 hours. It's usage time that really matters.
Mine dropped about 10% the first night (Mon 24th), but I do live in an area that has poor reception. Have to place phone next to window just to get text and calls. If I go outside I may get LTE at 1 or 2 bars. Overall though battery hasn't been an issue and I love the rapid charging.

Probably.
Using Accubattery to measure screen off battery drain I am typically between 75-85ma. Has anyone else measured their standby power consumption, curious what other values are as this seems high to me.
Edit: more info
Tested it overnight with and without bluetooth on, got it down to 40ma without bluetooth, averaged 70ma with bluetooth on overnight. Also got to test a Note 4 under the same conditions though without a SIM card. The Note 4 was using 11ma without bluetooth and 18ma with bluetooth on. Both phones connected to the same WIFI the whole time. May have to do a full reset on the Pixel as the standby power consumption is definitely out of hand.
Standby
My Google Pixel currently drains an excessive amount of battery even on standby, however thanks to quick charging its up and ready in 15 minutes. OS seems to be heavy usage of battery at the moment.

While I still think the Samsung will have slightly better standby drain, this isn't a good test. You cannot compare a phone with a cell signal to one without. The biggest battery drain on a phone is typically cell signal.
If you pulled the sim card out of the pixel and let the phones sit side by side overnight, that would be something.

I agree, this test is not a great comparison. The Note 4 did still have cell signal as they do connect to service without a sim card, but likely it is not the same as having proper service (LTE). I was trying to get the lowest draw possible on the Pixel and managed to average 29ma in airplane mode. This is the lowest I have got yet with the device which although is decently low draw is still abysmal considering that it had no apps running and no radios active. What is even more interesting to me is that google claims that the phone has 456 hours of standby time which suggests radios active (at least cell), unless my math is wrong this works out to a standby drain of 6ma which at least on my phone seems to be completely unattainable even with radios off.
I have looked around the forums but haven't seen anyone else posting power consumption information with the regular or XL pixel so I have no idea if this is unique to my phone or just standard with the Pixel. I haven't yet factory reset the phone but that would have been next, except that I am exchanging the device due to an unrelated issue. I guess I will see how the next one stacks up in this regard.
Thought I would post an update on my findings. After getting a new device and still having issues I have an answer and partial solution to my terrible standby drain. The culprit in my case is LTE. I am on FIDO in Canada which does use Band 4 though I am not certain if that is being used in my area. Anyways if I set my preferred network type to 3g my standby drain improves dramatically as the device idles around 10-15ma in my pocket and overnight is more like 6ma which is phenomenal. As soon as I set my network back to LTE my standby drain is 70-90ma and at best 40ma overnight if I'm lucky. My cell service for 3g and LTE are both good (green in battery stats). I know LTE requires more power however I would expect that power requirement to drop significantly when connected to WIFI networks which in my case doesnt seem to matter at all. At least now my battery life is awesome as others have reported. However connecting to 3g when away from home is a bummer and it's not really practical to manually change my preferred network every time I leave or enter a WIFI area. Looking at a way to automate this switch but on Android 5+ it seems that changing these settings via app are very locked down. I would also like to point out that my previous phones never seemed to suffer from this issue which only further makes me suspect that there is an unresolved underlying issue here (maybe related to the Band 4 issues being reported?). It sure is nice to open my battery stats window now and see some horizontal line segments instead of the linear march towards zero.
