Has happened twice now; When I stop using the phone and go to bed, I've got 33% battery left. Wake up in the AM and look at my phone, the battery is down to 13%! What the heck is it doing at night? I don't use 3G/4G networks at all, they're disabled. Wi-fi is on at all times, but sync settings are on only for Gmail, FB and Contacts....... Strange!
Could it be the flashing LED-light, that shows I've got new mail/messages?
i have 100% battery when i'm going sleep. On wake au battery is minus ~35-40%
no 3/4g, no WiFi
about 100 apps installed.
from here about 20 apps always trying to go in running processes. things like maps facebook mail.... it drives me crazy
try to watch battery graphs,
I'm sure you know about advanced task killer, Android System Info, System Panel Lite apps... with 'em yu can track phone activity... applicatio call, usage, battery graphs, .....
maybe you have some custom ROM like Revolution HD which is overclocking your CPU and GPU
Hi,
I have a HTC Sensation, not rooted. I use an 1900mah battery based on xda and other forum experiences, and it is better than the original but I still have problems. I use battery mix app for monitoring the battery use and usually it says CSPEOPLESYNCSERVICE is using the battery, always at least for 45%! If I unplug the device from the charger at around 8 o'clock, at the afternoon at 4-5,it's around 45-50%. The usage is basically 30 min music, 10-15min gaming, 20min browsing and approximately 20 min of voice calls and a few messages on whatsapp. I have unticked the sync for all the contacs( fb, skype, whatsapp, gmail etc) but when I check the battery usage in battery usage it still shows CSPEOPLESYNCSERVICE is using my battery mostly. If I check basic android battery usage it just shows mostly the display uses it. I have searched a lot about this problem but nothing found. I don't use anything special, I don't use appkiller, antivirus or any app that could run in the background. In my opinion it's not normal, thsi way my 1900mah battery with normal usage ( during the day I work, and not really using my phone like gaming or etc) lasts for 12-14 hours.
Thanks
Your battery life will improve if you set your network mode to "CDMA Only" rather than "GSM/CDMA Auto", because it forces your phone to stick to one network instead of searching for others.
Your battery life will also improve if you use a low-med static brightness setting rather than auto-brightness, since your phone will not be using its sensor to detect the background lighting.
It will improve further if you use an app that controls your network usage such as Green Power Premium which controls when your network should be on and off. Also it has a great feature that makes your phone to sync when network is on, rather than most battery apps that just turn on network pointlessly waiting for phone to sync itself.
Hope this helps =)
Other than battery life, I believe the ChaCha is one of the best QWERTY candybar Android devices out there (not much else to choose from...). So, I am on a mission to get as much battery life out of it as possible, without sacrificing much functionality. I've been experimenting over the past few months and here is what I've found:
1) SuperOSR ROM gives me the best battery life (compared to CM9, CM7.2, CM7, HTC Stock, ATT Stock and Telus Stock)
2) Backlight drains a lot of energy, so I set my custom Backlight settings as the attached jpg
3) 600Mhz Max CPU speed is a sweet-spot for battery life vs. performance
I tried to see max life I could get with various items enabled/disabled, here is a summary:
1) Airplane Mode @ 26hrs still 100% remaining
2) Voice Network On (Auto GSM/CDMA) @ 25hrs still 68% remaining
3) Voice & Data Network On (Auto GSM/CDMA), Background Data/Auto Sync Disabled @ 23hrs, still 68% remaining
4) Voice & Data Network On (Auto GSM/CDMA), Background Data/Auto Sync Disabled, Roadsync Exchange every 15mins @ 23hrs, still 66% remaining **
** This is a big one for me. I originally was using the built in Exchange/Email sync (15 min sync time), but this required Background Data and Auto Sync to be enabled. I would usually only make it 15 hrs or so with regular usage. Once I disabled Background Data/Auto Sync and switched to Roadsync (which still works with these disabled), I drastically increased battery life. The only drawback for me is needing to enable background data to use the Play Store (which I rarely use).
I searched for a decent explanation of what these two functions do, and here is my best concise summary:
Background Data: when enabled, applications can send/receive data even when you are not actively using them (i.e. play store app updates, etc.)
AutoSync: strictly controls whether the accounts (under accounts & sync) are allowed to sync on their own or not (i.e. built in exchange, facebook, twitter, weather, news, etc.)
Other items I set that may or may not save small amounts of power:
• Sound
o Vibrate – Off
o Haptic Feedback – Off
o Low Battery Sound – Off
o Pulse Notification Light - Off
• Display
o Auto-Rotate – Off
o Screen Timeout – 30s
o Animation – None
o Window Animation – Off
o Transition Animation – Off
• Performance
o Disable Boot Animation - On
o Surface Dithering – Off
• Sound
o Silent State – Enabled
o Vibrate During Calls – Off
o Mute Camera Shutter
• System Preferences
o Scrolling Cache – Disabled
o Wallpaper Hack – Off
Also implemented the Adreno GPU mod to is uses the GPU instead of CPU.
Hope this info might help someone increase their battery life!

Wow, that's a really long time! What are the details? I'm assuming data is off, looks like voice network is on, but I'll also assume you didn't use it during this time period (no voice calls, etc.)
http://forum.xda-developers.com/showpost.php?p=32368934&postcount=124
My measurements:
- HTC Stock ROM: 3-4 days
- CM9 ROM: 4-5 days
- CM7 ROM: 5-7 days
I use phone mostly for calling and calendar/mail. I have only a few apps/widgets installed.
No GPS, no mobile network data connections, no background data, no automatic sync.
Wifi are only enabled when I need it for sync or internet access.

Here is my phone setup:
CM7.2 build for HTC ChaCha with librpc.so from SuperOSR (http://forum.xda-developers.com/showthread.php?t=1912771)
ADW Launcher EX version instead of stock launcher.
Governor: Conservative, CPU: 245Mhz - 800Mhz
No animations, no haptic feedback, no live wallpapers.
There are 3 major battery consumers:
CPU: The CPU consumes most of your battery, therefore you should measure your applications/services how much CPU resources they need. There should be no unused services in your running services list and no (unnecesary) widgets which wakes up CPU to update information while the phone is in standby. The Temp+CPU monitor will show how much CPU your system ir using when idle or running some applications. If your device is using more than 4% of CPU when idle, open terminal and type top -m 6 to find which process is waking up CPU.
Display: display should switch off 30 - 60 secs when phone is idle.
Radio: You should enable mobile data connection, bluetooth, GPS, Wifi only when you need it.
Erm, question:
Why 30-60 sec when phone is idle?? Why not 15-30 sec? I mean, if it's in idle, that means that you don't use it. That means that you're not actually looking at the screen for anything. For sure, you might be reading something (like an email, or an SMS) but given the screen size, you won't spend more than 15 seconds reading without scrolling. My two cents. And a penny.
I agree that 15-30 secs would be better. I use 30 secs on my HTC.
Great info peleeks! Thanks! Couple questions:
1) Do you think there is much difference in battery life between CM7.2 (with swapped libprc.so) and SuperOSR? I figure they are both AOSP based.
2) Did you notice a big difference between Ondemand and Conservative CPU governors?
3) You mention about switching off BT, WiFi, GPS, etc. but from what I've read, the GPS is only active when an application (like Maps) requests it, so there is no need to manually turn it on/off. Similarly for BT, it uses very little power in standby mode and only consumes when in an active call.
4) For that screenshot where you get 7 days on battery - how many mins of voice calls are recorded?
Thanks.
1. I think there should be no significant differences between CM7.2 and SuperOSR in terms of battery consumption. SuperOSR by default have some google apps and services installed, however many users reported that SuperOSR has longer battery life.
2. I didn't test ONDEMAND governor.
3. Radio devices still consumes energy even if they are not used. With bluetooth in standby mode my laptop consumes noticeably more power than if I disable device in BIOS. Also for every device there is a service/driver which is running in background, locking system, polling device status, etc. There is a beautiful power widget in CM7.2 and SuperOSR - it is very easy to turn device on or off.
4. About 60 minutes of voice calls.

For this one I can chip in with some info:
Regarding GPS, it might be that the chip stays powered on and acquires your position the moment you turn it on; if you see the GPS icon in the status bar then this is true. It's also related to the Location settings, if you allow your device to use location based info to improve services and whatnot. The effect this has is that every Google product will search for location info, even if that application is not running. Keep this in mind; you might want to disable these options as well.
Bluetooth - It is indeed true that in standby mode it uses less power than active mode (active mode means having a device connected, not necessarily an active call). The problem lies in how the software is implemented by the people who released the drivers for the ROM. Nonetheless, it should be turned off if you're not using it. You can find a thorough analysis of Bluetooth power consumption here: http://nesl.ee.ucla.edu/fw/documents/reports/2007/PowerAnalysis.pdf . At the same time, keep in mind that different Bluetooth versions have different power consumptions. For example a device with BT 2.1 will loose more power when having BT turned on than a device with BT 4.0. Our ChaCha has 3.0 according to gsmarena which has a somewhat improvement in power consumption in different stages.
*background info: I work for a company that develops embedded and off-the-market BT car-kits, therefore I'm sick and tired of BT devices (phones, BT players, tablets, etc.). One quick example that we usually laugh at: iPod Touch 3rd/4th Gen in idle with BT off lasts about 48 hours, give or take. With BT on, not connected to anything, it lasts about 24 hours.
Well, been trying different methods in the last couple of months... CM9 gives the best life while using it the normal way... I can survive almost 46 hours with using data, calling, checking mail and everything. It's nice if you can run that long, but why bother about extra days when you can make it over 24 hours with normal use...

Thanks Alex for the info and link! Got me doing some more searching on power consumption and came up with this great article:
http://translate.google.com/transla...kulaufzeit-unter-Android-1145579.html&act=url
Combining this info with the one from the article you linked, it seems that Bluetooth and GPS don't really use much in standby mode - a few mW at most. So we shouldn't concentrate on them much when trying to conserve power, but rather to look at the larger consumers like unnecessary Data and Display usage.
Tried a stock ROM this weekend since the stock ROM has much better GPS fix time and faster Bluetooth connect for me. Unfortunately, it also has the dialer bug. I can't seem to find a version of the ROM that doesn't. Also, turning off the "quiet ring on pickup", etc. options has no effect on preventing the bug.
However, I did find a fix that worked great for me: Setting "gsm.proximity.enable=false" in the build.prop file
This disabled the proximity sensor so you have to manually turn off the screen on a call - no big deal for me as I use a BT headset all the time. I can confirm that this does the trick in terms of preventing the dialer bug/drainage issue for me.
Let's see what sort of battery life I get now from the stock rom...
The settings on the S3 have the following power saving options available: Auto adjust screen tone, Screen Power Saving and background color. Do any of these settings have a decent or better impact on battery life? I have a hyperion 4200 battery and use Lux autobrightness to lower screen brightness below zero when I dont need a bright screen, and seem to have my phone currently doing okay when it comes to wake locks, so wondering if these options make any noticeable difference in battery life or are they more gimmicky like a lot of the other settings choices.
I think the data syncs are more of a culprit than auto brightness settings but then again I have auto brightness on and it still helps. I notice my wife's phone gets better battery life than mine because she doesn't have as much data syncs in the background as I do even though she is constantly playing word games. She doesn't use FB, Twitter, Google plus, Google Music or Dropbox and I do. We both charge our phones at night but she has more screen time than I usually, stock batteries too.

I consider my battery life to be okay. I use my phone a lot so I cant expect the multiday cycles people have. I wanted to know this more for information. I have all my auto syncs off except for youmail, which i need on to update my custom voicemail greetings. To sync everything, i wrote a tasker action to sync everything everytimebi connect to a wifi access point other than gmail. For gmail, i have it set to sync every other time the screen turns on. I am able to do this because of the synker app from play store.
I'd say power save works. Extra hour maybe.
I turn off WiFi and data when I don't use it and my phone last all day with heavy texting and frequent WiFi use.

Share with others tricks used to extend battery life.
Tricks known to me:
1.Reduce your Screen Brightness
Display uses about 5-80% of battery usually. Reducing the brightness helps to increase the battery life a lot. To do so goto Settings->Display->Brightness
- Automatic brightness is good but lead to higher consumption of battery. Close brightness automatic and set brightness low.
2.Disable Wi-Fi, Bluetooth, GPS, NFC
Even though Wi-Fi, GPS and Bluetooth are designed for low-power consumption, they drain the battery. Most of the 2012 android devices have a unique feature known as NFC (Near Field Communion) such as i9070p. This feature enables a sensor field around the handset and is used for sharing. This also drains the battery unnecessarily. So it’s better to turn off the Wi-Fi, Bluetooth and NFCs when it’s not in use.
- Deactivate Wi-Fi when not needed
- If you do not use the Bluetooth function, disable it.
- If you do not use the NFC function, disable it.
- If you do not surf the internet stop any data connection
- As long as you do not use GPS and/or location services, close them.
3. Prefer Wi-Fi rather than GPRS
It may be weird that the GPRS consumes more power when compared to Wi-Fi. For example, Wi-Fi consumes 5% charge; the GPRS connection consumes 15% charge. This may not be seen while viewing websites but in case of watching a video in YouTube or making a call in a VoIP service, it drains the battery at a rapid rate. So it’s better to use Wi-Fi to watch videos or making calls.
.- Wi-Fi network consumes less than 3G connection, it is recommended to use Wi-Fi
4. Avoid Live Wallpaper
The live wallpaper drains the battery to a considerable rate. So it’s better to use static wallpapers rather than the live wallpaper.Also use images which contain black color because the LED screens use less power to display black than displaying white. Doing this helps to increase the battery life up to 10%.
-Use a dark background, save battery. Light backgrounds need more battery.
5.Disable Data traffic
Many applications use data traffic in the background letting this phone to sleep. Some of the apps which use the background data traffic are GMail, Whatsapp, Facebook, Viber, Twitter, LinkedIn, Google Play, etc. These apps checks for the updates and for incoming messages all time. So it’s better to disable the background data traffic.
- Network 2G network consumes less than , it is recommended to use 2G connection
- If you do not surf the internet stop any data connection.
6. Disable Auto-Sync
This option comes under the background data traffic. This feature checks for the mail all the time. Which means you will be able to get the mail in your handset as soon as the mail arrives. But this service uses a considerable amount of battery
- Upload and sync only on Wi-Fi. Or stop sync on all accounts.
7.Do not use more widgets
- The more the widgets, more the RAM, more the battery will be drained.
- Dump the widgets
8.Disable Adobe Flash
Adobe Flash enables to watch videos in websites but it drains the battery a lot. The main reason why adobe discontinued its service from android 4.1 is this battery problem.
9.Turn OFF vibrations
The smartphones makes use of some energy to make a vibration, but when “Vibration on Key press” is enabled, while typing a word the phone produces more number of vibrations. It consumes more battery. So it’s better to disable this feature in the keyboard settings.
- Vibration consume energy. A low intensity vibration or even disable as reduce battery consumption.
- Disable Haptic feedback.
10. Power saving mode
If you use your device constantly throughout the day, you may want to consider using your device’s power saving mode. In fact, many of the tips suggested in this post are implemented in most devices’ power saving mode. For instance, power saving mode usually limits CPU use, reduces screen brightness, deactivates haptic feedback, disables data network when the screen is asleep, and lowers the brightness level of the browser’s background color.
The generally recommended advice is to disable power saving mode when you intend to use your phone’s smartphone features; otherwise, turning power saving off can help you stretch your battery life further. So, for instance, you might want to disable power saving mode if you plan to play games on your phone, or else you could experience lag or jitter.
11. Do not try to overcharge
Normally the smartphone charges up in 1-2 hours. But if you charge it throughout the day, it lowers the life-time of the battery. Check the condition of the battery often to have a good battery life.
12.Reduce screen timeout
- Screen timeout should be as low as when not using this device to enter sleep mode. (15s)
- Sensitive buttons should be as little heated. (1,5s)
13. Uninstall unnecessary apps
You can never be too sure what's running itself in the background, what with all the multi-tasking, self-uploading, auto-replicating features in today's modern Android apps, so at least minimise the chances of something randomly hoovering up all your battery by constantly trying to connect to some non-existent server, by deleting any unused or old apps. Some apps are resource-intensive — either by nature (as in the case of games) or by developer incompetence or negligence (as in the case of poorly written apps).
14.Never leave applications open
- Never leave applications open in the background for long time. Set the limit to 1 or 2
15.To root or not
Rooting may have drawbacks but the benefits far outweigh them. One attractive advantage of rooting is that of possibly improving your device’s battery life.
16. Debloating
Rooting itself won’t lengthen your battery life. Rooting merely opens the gates to your device’s restricted partitions and directories. With such restriction gone, you can remove useless apps (e.g., bloatware from carriers or OEMs), especially those that run as background services, wasting away precious battery power.
17.CPU underclocking
With root access on your device, you can also install apps that can improve your system’s performance. A CPU controller app, for instance. Three names instantly spring to mind: SetCPU for Root Users, No-frills CPU Control, and CPU Tuner.
Apps like these essentially allow you to tweak the CPU settings on your device. You can set the CPU frequency to stay at the lowest (and, as a result, use up the least power but sacrifice device performance) or to stretch the CPU to its maximum limits (resulting in better and faster performance, but at the price of heat, quick battery drain, and potential system instability).
Be careful when using such apps. There are risks involved; for example, your device could behave erratically when its CPU clock is set higher than usual.
18. Custom kernels and ROMS
As we have an unlocked bootloader and custom recovery in the process of rooting. Many custom kernels and custom ROMs. Feel free to look around XDA for guides on how to flash custom kernels or custom ROMs to your particular device.
Battery life is one of the biggest issues in the Samsung Galaxy S GT-i9070 Advance. Take your SIM card out, turn off Wi-Fi and never touch it and it'll sit there happily, lasting for a whole week on one charge. But try to use it for anything "smart" and, well, that's where the problems start.
...and keep it cool
Batteries work best in cooler temperatures, with prolonged warm periods gradually lowering their efficiency over time. Putting your phone in a looser pocket might help, or perhaps just gently fanning it while it charges. That might not be the best use of your working day, but at least you'll still be able to get on Twitter on the train home.
YouTube Video:
http://youtu.be/shApI37Tw3w
The two attached images show the effect of these methods.16 hours with only 2G/3G connection for 1 hour, listen to music 15 minutes, talking on the phone 12 minutes, 10 messages, 1 hour and 40 minutes gaming and others. I left with 22% battery. To me now is night, which means the phone will remain at rest for several hours, and the battery life will reach one day to several hours.

Without a data connection active, our devices are basically 2G network. 2G connectivity is needed for calls, messages, etc.. Theoretically should consume less than a Wi-Fi network.
I may be wrong, waiting for other opinions. Thanks!
You have got a few wrong..
I do not respond to tech support via PM
It is my understanding that:
- If you are downloading//uploading data, 3G consumes more battery than WIFI (upload also consumes more than download)
- Idle: WIFI consumes more battery than 3G
Always a good idea to disable Haptic feedback aswell.
Keeping the phone always on Power saving mode is a good idea ?
Coz without that my phone battery wont last any long! in power saving it goes approx 15 hours including around 7 hours of deep sleep!

Yeah, why not? Power saving mode do some of the things said by me above and in addition reduces the CPU frequency to 800Mhz.

Disabling all the connections makes the whole phone quite useless.

I have to agree with you, disabling syncs or 3G connection absolutely defeats the purpose of having a smartphone. I do all the other stuff to preserve battery, i even have an all-black wallpaper.
You can space out some app syncing (facebook syncs for example and lots of apps can be configured to sync at specific intervals) to get a middle-ground solution.

I've disabled the following:
Bluetooth (if I need it I switch it on)
Haptic Feedback
GPS
Uninstalled bloatware with Titanium Backup (it helps, bc many unnecessary apps stay online and consumes both memory and power)
Installed Juice Defender Ultimate (auto disables Wi-Fi, BT, mobile data and enables sync at a certain time interval when you don't use the phone)
Use Mobile Data only when Wi-Fi is unavailable
Enable Power Save.
With this setup, I have all day power, and charge the device only when I get home.
