Hoping someone might be able to help me here..
Within an hour of being taking off the charger (and confirming it was 100% at that time) my battery life is down to 80%.
What's happened so far is:
1) alarm went off (set to ring only - no vibrate)
2) recieved 2 emails on yahoo (set to check every 60 mins)
3) received 1 push email through exchange/active sync
4) 1 calendar appt reminder.
The screen has probably only come on 3 times for no more than 10 seconds each time. My brightness is set to the 2nd lowest level possible. My ringer is on the highest.
Here are the apps I have installed. I have not "launched" any of these today.
.net 3.5
Easy Shares
Google Maps
Microsoft My Phone - (set to sync once at 3am & was on charger then)
Mobil manager for netflix
S2U2
Waze (another GPS app)
Phone is about 4 weeks old.
download HD Tweak and set up data disconnect after to 1 minute. I am almost positive your data is staying on after downloading email because i had the same problem with my Touch Pro. Keeping the data session open is a huge battery drain
My battery life is terrible too! I charge it fully throughout the night and the phone typically dies by the time I get home from work at 6PM or so. I barely use it at work. Never talk on it. The occasional text message. But by the end of the day the phones dead. I have no idea why. I know for some odd reason by phone will not automatically go into sleep mode. It should, but doesn't. Not sure if that kills the battery even though I manually push the sleep mode button each time.
I set up the HD Tweak software. We'll see if this helps. Does it work for the Touch Pro 2 also?
Any of you guys using a case with a magnet on it by any chance?
Possible explanation...

Just curious, did you charge the phone while it was on? If so, I've found it a problem. I once charged my phone while it was on, and I took it off after about 2 hours (the green LED indicator probably showed up an hour before I took it off). I checked the battery meter and it registered at 89%! I found out that there's a flaw in the way the found charges. Once the LED turns green for a full charge, the charger cuts off, but (I think what I'm about to say might be true) the phone thinks it's running something as it charges, thus causing the rapid battery drop.
Since then, I stopped charging my phone while it was on. I now turn off the phone and then charge it. I can last a whole day with about 45 minutes total on the Internet, and my battery would go to about 60+%.
However, as jaas666 pointed out, are you putting your phone near a magnet? The magnet tricks the phone into thinking the stylus/keyboard is being pulled out, thus causing it to wake up, which will drain your battery.
Have you tried a task manager to see if a program is running when it's not supposed to?

I had terrible battery life and found two issues. One program was always taking up around 10% CPU usage (VZO video chat software). Also found that Google Sync, set up through ActiveSync, was having trouble. I'd open ActiveSync and find it in a synching loop. For me the solution was to untick "Tasks" in the sync menu. Since then, battery life has been great.

HD Tweak works fine on mine, I've also heard of some people using Diamond Tweak. I mostly text all day maybe some internet but I have gone a day and a half without charging and even then my battery had only gotten to ~20% so I think with a few changes it could be fixed. I'd check out some of the Tweaks threads here and at PPCgeeks for registry edits u can do to save the battery too
I had those issues with my 2000mAh battery on my sprint tp1. With my verizon tp2 my battery life is fantastic. I use the crap out of it all day also. Was wondering if the bad battery life is happening mostly with sprint users.
I have my active sync connected at all times for wireless email calendar task syncing. I charge with the phone on all nite long and the battery drains only slowly throughout the day. Less than 50% today. It is on 24/7 I never shut it down unless I'm soft resetting due to a file or app install. I use my ms3.5 task manager to keep stuff closed after using. I always put it to sleep mode by the button when I'm done with it. My screen is set to brightest and stays on 2 min. before sleep mode engages unless I manually do it.
I'm sorry to hear your battery issues, my tp1 with sprint was really hard on battery juice. I found it would struggle to find a signal alot, one reason I switched to vzw.
Hope you figure it out.
Sad to say that my less than 4 days old Sprint TP2 is disappointing to say the least in battery life and all around usability. Now i'm coming from a Treo Pro and so used to one handed operations and such. But i digress...
Battery life on this beast is sad, really sad. Someone alluded to Gmail Exchange ActiveSync as a potential battery drain so i might look into that. Basically i'm gonna hard rest and start from scratch applying less tweaks. Basically i find TF3D tedious really..takes too many steps just to do some basic things. I turned it off and managed better a bit but i just might go back to my Treo Pro and sell this thing..
My battery "appears" to drop quickly, but actually hangs in there quite nicely. My old phone only showed me 20% increments, so going to 1% makes it very noticable.
I ran cleanup first thing, then went back and customized.
I use Activesync in push mode (7 days per week 8am - 9pm), have it checking Hotmail, stocks, weather every 30 minutes. BT is on, Data on, WiFi off. I even went back and turned auto screen back on as I couldn't read cleanups default change in the sunlight.
Gets turned on at 7am, and at 10 pm I'm ussually 30-40%. Medium user - 40 minutes phone use daily, 1-2 hours total IE time, ALOT of email checking, hardly any SMS.
I do use a magnetic holster too. S2U2 fixed that issue.
Biggest drain I noticed is screen. If I turn off auto and go back to CleanUp default, I can get through almost 2 full days if I turn it off around 11pm, and back on 7am.
And as far as battery total use, my older phones always turned themselves off at about 15%. THIS THING WARNS ME AT ABOUT 4% and turns off 2-3%! That's alot of extra battery use.
There is a company making a 1750a battery that will fit in stock case.

Not sure if this will help you but some phone cases can cause battery drain. Read here:
http://forums.wmexperts.com/showthread.php?t=175441
Hi all,
My father bought an HTC Touch Pro some time ago; I think it was in 2008, as he needed a good phone, with the organization capability that WM has to offer.
The phone is in MINT conditions, really. It still has the original screen protector and no scratches can be found on it. He uses it a lot, but always has it in the leather case, and in a small pocket, which sometimes results in lost calls, as no one can really hear it ring . The battery is always fully charged, and after some testing I think it is still in good conditions.
The problem that he started getting is that after I installed some programs like GPS Tomtom and AGEPhone for SIP calling that he never uses (hehe), he started noticing the battery was discharging faster and that it would not last even 1 day, when before it would last about 3-4 days.
I uninstalled the programs, and the problem persists. Brightness is on 50%, wifi and any internet connection is turned off. No programs running in background, unless it's active sync that sometimes turns on itself.
POSSIBLE CAUSE - We noticed is that he has a lot of reminders, so the phone is constantly waking up. The problem is that it does not go to sleep afterwards. The touch screen is locked, so when a reminder pops up, the screen stays turned on, even if the backlight is not on, and just drains the battery completely.
Is there anything we can do, so that it (the reminders of meetings, birthdays and other stuff) would not wake the device up, or if it did, the phone would go to sleep after some seconds, so that it would not overheat and drain the battery in 1 day?
It is a quite annoying having to constantly look at the phone, dismissing reminders and turning the screen off, so the battery can last a bit longer.
I need to solve this problem, but my father will not agree with a custom ROM flash. Maximum I can do with it is upgrade it through the HTC tool, but I am not sure if it is worth it.
Here are the information:
Version de ROM: 1.90.406.5 FRE
Date de ROM: 08/20/08
Version de radio: 1.02.25.19
Version de protocole: 52.33.25.17W
The device was bought in Luxemburg and has a French windows mobile 6.1 on it, and an AZERTY keyboard.
Please help me with this issue.
Get tBattery and check to see the current draw under stead, idle conditions. With the backlight at 5, it should draw about 110 mA (there may be some spiking). Use the log feature, say for 10 min @ a time, with power-save options unchecked so the screen doesn't dim and it doesn't go to sleep. If the drain is high (constantly above 200 mA, let's say), then get a good task manager (hint: new dotfred's 3.3) and start killing processes, and see if that helps. If not, then try stopping some of ther services.
Thanks Farmer Ted for the reply, but I think I found the cause of the problem. I don't know why but after it wakes up, because of an appointment, it will not turn the screen off, even after 10 minutes and I have the power management set 30 sec off if not being used.
As the screen is locked, the appointment will not be dismissed by accident or pressed so it just stays like that, until the battery is dead.
Is there a hidden option to make the phone go back to sleep, or to prevent it from waking up, just making the led blink, as when you get new SMS messages and the screen is off, or when you get a missed call?
If there was I think it would solve the problem completely.
Thank you all for your help.
yes the problem is the screen it drains it faster than a hobo with a bottle of wiskey,
what you have to do it click on batter icon and get into the battery menu select advanced and elect turn back light off if device is not used for and select 10 second, then turn off device if not used for and slected 1 minute (its reffering to the screen)
then i use a program called touch pro tweak (its cooked into all energy roms) and there is a setting to wake up on call or text or notification and disable it by wake up it refers to turing the screen on
I have a simmilar problem.. I discovered what causes it... When I install certian programs, it changes the power settings.. namely, the power off when not plugged in setting... So, check out those settings... I have had this happen 3 or 4 times in as many months... then I notice the same issues with my battery.. after I go change the settigns back (for the 100th time) it goes back to pastign 2-3 days for me... (instead of less than 1)
Hi people, sorry to bring up this topic again, but I see no point in creating a new one.
I would like to ask if any of you would recommend me a good French ROM (as it comes with AZERTY keyboard) for this device that has good battery life?
Is it possible that a cooked WM 6.5 would use less battery then stock WM 6.1?
I have another problem, is there a way to turn up the ringing volume of the phone, in order to hear it even if it is in a small bag? It's already on max, but my father complaints the ringing volume is too low and he can not hear it.
And last but not least, how much does this battery normally last? Wifi off, bluetooth off, calling about 15 min a day, some SMS and a lot of reminders.
It can not go a day, max two days without recharging. It is always turned off when he goes to sleep, because if not, he will wake up with a dead device.
TL: DR - Use Rescan Media, win.
So, I think that I've finally found the source of my constant stress regarding the battery life of my beautiful Samsung Captivate SGH-i897.
I know that a good majority of you have just rolled your eyes in disbelief, or just thought to yourself, "Great....another one of these threads".
If it helps one person get their battery life under control, then roll away.
I've had the phone for about 2-3 months and I've been active on these boards since a few days after getting it.
I've recalibrated, done the on / off / on / off trick, battery stats delete, deleted battery info from CWM, tried a second battery, used battery monitors on the phone, turned off wi-fi, turned off auto-synch, turned off bluetooth, lowered display brightness, and everything else I could think of to conserve juice.
Yesterday afternoon, I downloaded OSMonitor from the market in an effort to try another app in a long line of failures.
Nothing seemed out of the ordinary so I was going to give up hope.
While installed, I had clicked on the box to monitor the app in the notification bar.
I noticed that I would have times where the CPU was being maxed but nothing strange was being reported in OSMonitor.
And then it hit me.....
The entire time I'm watching the OSMonitor, I'm being distracted by the media scanner.
It's running over and over and over and over and over.
When the screen shuts off after 30 seconds, it comes back on, the media scanner runs.
When I update something from the market, the media scanner runs.
When I close a program, the media scanner runs.
It is running constantly and maxing my CPU to 100%.
It finishes fairly quickly, (I have 9.4GB / 13GB available on internal and hardly anything used on my 4GB external SD card) but it just KEEPS....ON.....RUNNING.
I do a quick search, stumble upon the .nomedia file trick from XDA archives, and VOILA ! ! ! !
I'm losing about only one half of one percent per hour while it sits on standby, where I would sometimes lose 10-11% per hour, when the phone isn't even being used by me.
I went to bed last night with 48% at around 3:30am.
It is approx. 11 hours later right now.
I've made approx. 8-10 calls, checked my email a few dozen times, and mostly just let the phone sit.
I'm sitting at 39%.
Previous to doing this, I would have lost that amount in one hour.
So, for anyone who has a phone that is losing battery life like it's going out of style, I highly recommend doing the .nomedia fix.
I did mine using ES Explorer and Super Manager.
Go into your root folder and add a file named .nomedia, then go into your external SD folder and do the exact same thing.
If you do not want to do it this way, you can go the easy route and add a program called Rescan Media that does it for you.
(link supplied)
Hopefully this helps at least one lost soul, I'm so happy to see my phone behave more along the lines of what my expectations were and not have to be fully charged 2 times per day.
For the record, I've tried the following ROM's for the Cappy:
Perception
Phoenix
Assonance
Darkytt3r's port of Darky's ROM
Stock ROM (ODIN Rooted)
Cognition
And the following kernels:
Glitterballs
SpeedMod
SetiroN
Xcalibur
Will this not cause the media scanner to not pick up anything at all then?
IE no custom ringtones/msg alerts, nothing displayed in gallery, playlists wont work with the music player....
Or will it run media scanner selectively instead of all the time?
The only time I notice media scanner running is after rebooting the phone... yet I'm still only getting about 9-10 hours on a full charge with very conservative use.

When you say the media scanner runs when doing all of these actions, does the Media Scanning icon show in the notification bar? If so, then I think it's just an issue with your phone cause I don't think that happens with anyone else's phone.
Unless you are saying that the media scanner runs in the background secretly after every action and there is no icon in the notification bar or anything? If so, I think you can be on to something.

You could just run Media Scanner manually. SwitchPro even gives you a button to initiate it. The only time Media Scanner runs automatically for me is when the phone boots (and probably some other infrequent times that I can't remember) so disabling automatic media scanning isn't much of a loss at all for me.

I'll be nice... see the quoted paragraph that was in your quote?
Minlee, no need to quote an entire post, especially when you aren't responding to something in it directly.
As others have said, I only ever see Media Scanning in the Notification bar when I do a reboot. If it runs at other times it is transparent to the phone.
This is probably an issue specific to myself and a few others.
Someone above asked me if I saw a lot of activity in the background or if I actually saw the "Media Scanning" icon pop up in my notification bar.
The answer is that I saw the icon pop up and then watched it scan, over and over and over, all day long, dozens....if not hundreds of times.
That little fix, coupled with the battery calibration that I've done a few times, along with getting rid of some of the resource hogs that run in the background (Do I reeeeally need Google Maps to run 23 hours out of the day???) has given my Captivate new life.

Yeah, I've never seen that kind of behavior. I only see the scanning activity when I first boot and when I do something like take a picture or a screen shot.
I am running Caulkins Rom 1.1 with Clemsyns kernel version 5. I was continually having problems with the tablet not waking from sleep. I have searched and read till I was blue in the face.
I decided to try the long tedious method to troubleshoot this. I did a complete wipe and reinstall without installing any other apps and lo and behold no problems with sleep. I then began installing my 30 or 40 apps one at a time to see if any of them would affect the wake from sleep as I had read on other threads.
The very first app I installed was Fancy Widget. I put the tablet to sleep waited about 10 minutes and it would not wake up without a reboot. So I uninstalled Fancy Widget and sure enough no problems.
Next I tried an app called Gizmo for streaming music from my home PC. It would play one or two songs and then stop and sure enough not wake from sleep. I then tried changing the setting to keep the wifi on at all times in settings. This did not help. I am now trying Wifi Keep Alive but that just quit also and had to reboot.
It appears with just the first two apps that I tried that the tablet is actually locking up when an app tries to access the wifi during sleep. It is not actually shutting down but rather just freezing as it continues to use battery and you have to do a long press on the power button to force a reboot.
Without these apps the sleep function works great. The streaming apps are kind of a pisser though since I would really like to listen to music.
Is there a way to disable sleep completely? Can anyone test out Fancy Widgets and see if it causes them the same problem?
Todd
I can second this wifi sleep theory. I haven't had any sleep of death issues since I changed the wifi sleep policy to "never". I honestly didn't connect it since I did so after flashing a new rom. But now that you say that, I'm remembering if I had Pandora playing when the screen shut off, I couldn't wake the screen up unless I reset it, but the music would continue playing until I rebooted. Maybe some other folks would be willing to set their wifi sleep to never and report back? I'm on Calkulins ROM btw.
EDIT: In case you aren't sure how to change this. Settings>wireless and networks>wifi settings>advanced settings>wifi sleep policy
After further testing here is what I have come up with.
Fancy Widget definitely causes a freeze.
Streaming music seems to only freeze when I am streaming to my bluetooth speaker. I have had Gizmo running for almost an hour now playing just through the Gtab speakers and it is fine. I even tried streaming to the bluetooth speaker with the screen set to never shut off and it completely froze the Gtab. I had to hard reboot with the power button.
So I am back to trying to troubleshoot bluetooth problems which I have had no success in doing. I have posted bluetooth questions a couple of times and gotten no responses.
Any bluetooth gurus out there?

Clem's 7 fixed the sleep issue on my new gtab. Oh yeah, using you're (roebeet) TnT 4.3 mod (thanks), when did you release 4.4?
I have no sleep issues now except for the above mentioned. My battery life is awesome now as well.
I solved my streaming problem by buying a 6 foot 1/8 to 1/8 cord and plugging in my speaker. Kind of defeats the purpose of buying a wireless speaker but it works
Interesting. Not positive but I think my sleep issues started after I installed Fancy Widget. I'll uninstall and report back.
No Fancy Widget and so far so good.
Hello Forum,
why does my alarm clock work while the phone is turned out? What is the name of this function and how can I turn it off?
I think it uses battery, because I charged my old phone (switched off, emergency phone) a week ago and now its empty.
Thanks
Peter

Hi, what phone do you have ?
I remember this was an issue for certain phones (but that was 6 years ago lol). Your phone must be really old !
And about the battery life when shut down, how long does it last usually?
Now for the upfront solutions:
Delete the alarm you sat up.
And if you have a removable battery on this phone, removing it would have a very good effect on battery life.
Have a good one
Its an Elephone P7000. I want to charge it and use it as a secondary phone. I turn it only on when my main phone has no battery. Last month I bought a new battery for this phone, on the battery is written "production date 2015". The battery last a whole day when the phone is turned on.
I'm really interested what is running the whole time in the background when Android is turned off. Is it some kind of BIOS? Is it the bootloader? Can you give me the name of this "program"?
PS: When my Xiaomi phone if turned of, the alarm does not work.

PS: I have never heard of an android phone that respects alarms when the phone is off, as android is not running But I always wondered why not, since my previous non-smart phones all did.
This App analyses the energy consumption of Android and the Apps, but that is not my problem. My problem is that the charged phone loses energy while it is turned off.
And secondly I'm really interested what is running in the background while the phone is turned off. Is is a firmeware from Elephone? I removed the original Elephone rom and switched to Cyagenomod and then to Rublix. But original Bootloader and other Elephone stuff my still be there.
I asked in a german Android forum and they said it is the fastboot function. But I think this is only a possibility of Android to boot fast when is is wakened from the watchdog I'm searching. (That the alarm clock starts immediately and not minutes after the targeted wakeup time.)

Yes, when you flash a custom ROM, all you are really changing is the system partition itself and maybe the kernel, everything else from your original firmware is still there: e.g. bootloader, modem, etc, etc..
Fastboot has nothing to do with how quickly the device boots, fastboot is a bootable function/mode used to flash/manage the device using the adb/fastboot software while booted into fastboot mode. Some devices have a feature that allows for fast booting, but that is a different animal than fastboot.
Your device has an internal clock the same as a PC does, that is how a PC keeps correct time even when the system is powered off and still shows the correct time when you boot the system. As for what is causing the battery to die even turned off, that may be a different issue than the power used by the internal clock.
All of my old devices lose charge after sitting in a draw for some time without being used, it isn't really an "issue" or problem, it is just the nature of the beast. Batteries do not store power indefinitely.
You can find out more about lithium-ion instability and the particulars of their construction and how they actually work if you do some google searches on the subject.

Are you rooted? running Magisk?
The smartphone is rooted with SuperSU.
This watchdog is more than a Bios clock. It wakes the smartphone at a given time. So the android system configures this background watchdog somehow. Maybe there are more things that it can do?
My Motorola Moto E (LineageOS) starts always with a wrong time. (WhatsApp is complaining about it at the start) So there seems to be no watchdog.

OK, if you are rooted, I would try running a boot-script that logs what is running on your phone every X minutes. If your lucky, the boot-script will log while the phone is "OFF".
something like the following maybe:
Code:
#!/system/bin/sh
top >> /sdcard/runnig_processes.log;
You may need to find a path that is actually mounted in your "OFF" state.
Also, I wouldn't keep this as a permanent thing, simply a test.
I dont think that this works. The uptime shows that the smartphone is running since 6 hours. I think if I put the script somewhere in the android system it wont be executed while android is turned off.
I have done some search. It seems that the P7000 has a Real Time Clock (RTC) in the MT6752 SOC. This chip can be configured to wakeup Android. I can see it at "cat /sys/class/rtc/rtc0/name".
There is also the charging screen despite the phone is turned off. The SOC can do a lot of things when android is not running.

It does sound like android is not running on your phone for the phone-off-alarms, since it has a real time clock (I didnt read it, sorry).
As for the charging animation, all my phones have that too, but I think that is only the bootloader and ONLY while charging. ie connected to power, so discharging isn't an issue.
I suggested the above, as waaaay back when I modified my first phone, when I added a bunch of boot scripts that logged heavily, I *think* i was surprised when I noticed once (its back in gingerbread days) that I had logs from the start up of when I turned it off. But that was now many moons ago. It was just an idea, that shouldn't be too hard to test, even though all you have said points to it failing. And now that I think of it, the charging animation on that first phone I had, was actually PNG images (as animation frames) sitting on the android file system path; but again, that was during charging, not completely off.
