i have been reading about some of the battery u guys get and all i have to say is......how do u guy get such great battery life?! i don't get any where near that. thinking of deleting pure calendar since i heard it takes up a lot of battery. but do live wallpapers eat up that much memory? i got other widgets like beautiful home (updates ever 15 minutes), Mobile Buzz widgets, myspace (yea i kno. cant seem to get to facebook yet. unless some of you guys want to add me there ) widget, Process manager widget, Touiteur widget that updates every three minutes, FML widget, some beautiful home widgets, Yahoo NFL widget, Android Guys widget, i have Nimbuzz IM always running, Weatherbug on my notification bar that updates every 15 minutes, battery indicator, and wifi (when im at home). my display at 140/225 (power manager) and i have most of my widgets on ignore when i hit the kill all button on Process manager. what apps you think that i don't need to have running would help battery life? you guys that have SetCPU, what can u recommend to set my profiles at to see better battery life? my current set up is:
Charging
998 Max
245 Min
Sleep/Standby
384 Max
245 Min
Power > 100%
998 Max
768 Min
Power > 30%
614 Max
245 Min
what do you guys suggest to improve my overall battery life? ANY help at all will be greatly appreciated
**PS, i do the average usage of web, IM, a lot of texting, little to no myspace, twitter always running, and some flash video. also is it bad if i charge the battery a lot?**
I've had most noticeable battery improvements from using JuiceDefender and Switching the Network Type to GSM (auto) PRL. Generally getting about 17 hours with I would say heavy usage.

i guess u shouldnt be using
998 Max 768 Min on <100 setting to save battery..
imho the default 998 Max 245 Min ondemand (read setcpu=off) is the best setting..
afaik cpu lowers the clock on sleep by default.. so why bother?
same goes to all app-killers and auto-process-killers.. not needed =)
All those things that update frequently are what eats your battery. Every time an app wants to update it has to wake the processor and radio connections, do its thing and then shutdown again. If you've got this happening every few minutes your battery won't last the day.
I don't have anything updating more than once every 3 hours. That way I get 2-3 days battery life unless I'm using the phone heavily.
p.s. app/process killers won't help. Infact they generally make things worse. If the processes are sleeping (which they will be if you aren't using them or they aren;t auto-updating) then they don't use any processing time or power. Auto killing processes does however use power......

Exactly what my reply was going to be. If you don't need all that stuff, then either turn off the widgets or set them to only update every 1+ hours. The internet will kill your battery. Its nice having stuff at your fingertips everytime you turn your phone on, but are you really checking it every 10-15 minutes?
Live wallpapers also use more battery than regular ones, so even though they're pretty and nice, they can use more battery. I'm not sure how much more though, it might only be .5-1%/hour extra.
Also, if you want to use SetCPU, take t0ols' suggestion. If you're setting the minimum to 768, then that's the slowest it'll run. By default, it'll clock itself down to 245 even without SetCPU. You can also try changing the governor for the Sleep profile to Conservative or Power Save instead of On-Demand. With all that said, I've uninstalled SetCPU and my batter life isn't any worse or any better than when I had it installed. There's a thread on here where half of us say it doesn't help any and half say it does, so you might try uninstalling it too.
As far as the process managers go, I keep one installed, but only to kill some apps that continue running in the background. I don't auto-kill everything. For a while I was having pretty bad battery life while I didn't have a process manager, once I installed it, I noticed there was an app that was running in the background, using data. Some apps just aren't programmed very good and require manual killing.
Another thing, which I didn't see you mention, is screen brightness. Either set it to auto or set it to something less than half. The screen is one of the biggest battery killers there is.
Another one is your network connection. I usually leave mine on Edge only and use WiFi when I need something fast. 3G/H uses more battery than WiFi, so I'll leave WiFi on all day. If I go away from a connection though I turn it off to keep it from hunting for a WiFi signal.
If you must have 3G on, try dialing *#*#4636#*#*, go to Phone Information, then scroll to the bottom for "Set Preferred Network Type" and set it to GSM Auto PRL instead of WCDMA Preferred. Some have reported that this helps with their battery life.
Hope that helps.
Isn't this a duplicate of a duplicate of a duplicate of a thread?
My N1 with K9 Mail (2 online IMAP, 4 poll folders), Latitude, random stuff, including Pure Calendar... 3%/hr. That's as good or better than my previous smartphones. Google syncing cal/contacts, but not mail.
I don't have Facebook or Twitter syncing.
I'm happy with the battery life.
I'm wondering if my battery drain on standby is normal so I want to know yours. I see some people with 4-5 mA drain and that makes me think whether my drain is on the excessive side.
batery drain: 11-12 mA. sometimes jumps to 130-200 mA, i wonder why?
What's on: background sync, 3g.
what's off: gps, wifi, auto-sync.
auto updating apps: yahoo mail
Please follow that format if possible. Thanks.
Your battery consumption is good, you will have around 5ma too by turning off 3g data. The 130 ma thing is due to automatic update somewhere. (mails, rss, facebook etc)

the only app that updates automatically is yahoo mail, i'm sure of that. so the jumps is a mistery to me. sometimes the jump is above 200 mA.
standby battery drain: 5-7 mA.
What's on: background sync, 3g, auto-sync, gps on but no apps using it, tasker, systempanel.
what's off: wifi, bluetooth.
auto updating apps: yahoo mail
if switch to 2g, standby battery drain can goes down to 3mA

-mine is playing at 10-13 mA on stanby. Now it is at 133-153mA while making this post.
Whats on: background sync, 2g
Whats off: gps, wifi, auto sync
Auto update app: yahoomail, yahoo messenger, gochat.
I have jumps sometimes but not as high as that.

I know this is noob-ish, although I consider myself somewhat seasoned, but what app (or other method) are you using to measure battery drain? I'm running shubcraft 2.0 over ChuckyROM and in standby all day won't last more than 11-12 hours. Ouch.
Thanks in advance.

CurrentWidget, free in the market.
Thanks so much!
My drain is mostly about 5mA. Sometime it is between 5-9mA.
I have nothing that sync automatically, but I have those jumps too. Mostly they're between 150-200mA. How often do they appear in your phones?
So, know whats on:
Data, GPS on but no apps using it, Systempanel, Facebook, Whatsapp
What's off:
WiFi (but the same standby if I'm using WiFi instead of 3G), bluetooth
In airplane mode it's only 2mA, sometimes 3
My drain averages about 5-7mA with the combo in my sig
3G on all the time (not a single data drop on over 3 days as well, best rom I've used), auto sync on for facebook and google contacts etc every 20 mins.

wow what else do you do? my phone jumps form around 134- 334 something with almost everything off
Mine is usually in 65-70ma range. There really is something wrong with it.
Are there any places to check for battery drain? I tried a blank data.img, which did not help. (I'm on HyperDroid 1.7).
4-8 ma in standby. i guess this is a good value!
wm rom: goatrip android 1.0
android build: mdj froyo revolution 2.3 with S7 test 3 kernel
radio rom: 2.12
my drain is between 2 and 5 mA in standby condition with background sync, 3g, data on. According with autoupdate scheme it's jumping to 135 mA
My configuration is as follow:
WinMo rom: VBNDroid-Reloaded2Alt-24634-Oct13
Radio: Radio_2_15_50_14
Android Kernel: hastarin 8.5
Android rom: [Everyday Builds][latest linux_on_wince_htc][PPP] CM6.1+
SetCpu: 245-1190MHz, Interactive governor plus screen off profile 245/245MHz powersave
My cpu is also undervolted: Hastarin CONFIG_HTCLEO_UNDERVOLT_800
My quadrant score is around 2000
No problem at the moment with this configuration. I have been running this for 2 days

- am, nothing. Just those and some of the usual apps current widget list as running in the background. I just use set cpu that's it.
Sent from my HTC HD2 using XDA App
Build - MCCM 3.3
Kernel - Hastarin 8.5
Radio - 2.10.50.26
WM - Cleanex OzRom
Between 4 and 5 mA in standby which equates to a loss of around 1% an hour. And with what I would call normal phone use I usually have around 30% charge left after a 16-17 hour day, sometimes a bit more, sometimes a bit less. I have stayed with an older radio because I have never had any issues so have seen little point in updating it.
I am more than happy with my battery life.

It's good that you didn't change. I think 2.10 is very stable. I'm using 2.14 and I think the standby was better with the older ones. But how much do you use your phone during the day? Mine is at 40% after 12 hours of moderate use. I think this should go better

What I would call a normal usage. On average around 5 phone calls totalling around 20-25 minutes, some wi-fi and data usage totalling around 30 minutes, some game playing and a lot of display usage as I read books using FBReader while commuting.
This is all guess work though if I'm honest, I have never measured exactly what I do with my phone each day because as long as I get through the day without it giving me low battery errors I'm happy. I would say I have been on 40% after 12 hours use quite a few times, that doesn't seem unusual to me.
My average battery drain is 3ma to 5ma
With wi-fi on 7ma
I'm seeing spikes upto 400 ma.
I assume this is because I am running the stock WM ROM?
I'm new to hd2 (from HTC legend).
Will using a custom WM ROM like chuckydroid get my battery running sweet ?
Gotta say hd2 is a dream !
My x10 overheat now 48 degree celcius is normal temp n battery drain very fast. I also see that my cpu run all the time at 998 mhz this is not happen before 2.3.3 i dont use gps , wifi ,bluetooh 3g i have 2g network.plz help me friends!!!!!
i think it can make damage to your phone,update it again or flash it.
What are the programs consuming the battery in battery stats ? Do you have a huge photo and music library ?

Yeah, i have the same issue, i do have a huge library
From CPUSPY I saw my phone will either in deep sleep or directly hit up to 998...using WB TW GM rom BTW...
same here , cpu using only 998, 245 and deep sleep
same here. using pre-rooted stock. cpu spy shows that it mostly uses 998 and then deep sleep. 245 only a little, nothing else.
it makes phone heat up a little when using it and charging takes longer because of this. Even on wall charger.
I installed Wolf's ROM and took out all Timescape / Facebook / Twitter stuff ...
CpuSpy shows:
63% deep sleep.
29% 245
6% 998
No sync with Google, no Gmail built in App. I use K9 for 2 accounts refreshing every 15 minutes, my Image monitor widgets for every 30 minutes and Snowstorm for weather. WiFi was on all day (I've set no sleep policy). But was Sunday so not that much "work" (testing some app, etc).
Tomorrow I'll see.
hi there,i've got the same probleme,any solution ?
Hi,
I rooted/overclocked (to 1.4Ghz) my Xoom a couple of weeks ago and everything seemed ok, all of a sudden though the battery is draining rapidly throughout the day.
In standby with light usage over the last 5 hours the battery has been depleted by nearly 30%, by light usage I mean I looked at my tweets in the Twitter app for about 15 mins.
I keep the screen brightness on auto but it generally stays quite dim, in SetCPU the scaling is set to OnDemand and the Xoom is connected to a wireless network with almost full signal so it's not constantly searching for a network. Before I rooted the battery would last for a few days with average usage and now I'm charging it every night.
Any ideas what could have happened? I'm running the 2.6.36.4Tiamat-Xoom-v2.0.0-Katana-GPUOC-gfed7aa6 kernal.
Thanks,
Rich

You are overclocking. That will drain battery faster. Also you didn't mention if you have set profiles in Set CPU to save battery charge when the screen is off, for instance. I set mine on interactive, as well, as Team Tiamat has advised. Also look at what is using your battery the most--screen will be most of it. Also, some apps try to sync all the time and your battery can drain faster that way.
Well I knew that by overclocking I'd drain the battery faster, but I didn't expect the drain to increase so dramatically! You've made a good point with the profiles in SetCPU, I'l be honest and say that I havent really had much of a look around the app other than overclocking the CPU and using the info screen to check the temperature, benchmarking etc.
I'll give the profiles a try, with regards to apps that sync data constantly I've only used the email, gmail and twitter clients for this since I brought the device so I wouldn't have expected this to contribute to the increased drain.
I'm no noob to Android devices and rooting but overclocking is a whole new thing to me
So you overclocked your CPU and gpu to use twitter and the gmail client?

Errrr no.... they're just the apps that are always syncing data from the web, I was giving an example of the apps that are always syncing to answer the previous poster's point that a lot of apps will sync data in the background.
--Update--
Adding a ScreenOff profile to SetCPU didnt help very much, set the max CPU to 312 and min to 216, also set scaling to Conservative. Proceeded to charge the Xoom to 100% and then left it on standby all night, this morning the battery was down to 68%.
I've now restored my Xoom to a backup I did the same day I overclocked it, as I mentioned in my original post this issue only started a couple of weeks after overclocking.
Hey there, I really have on problem with my N4 since I own it:
From time to time my battery drain just goes huge. For me it feels like that is everytime I go out and have my phone in my jeans pocket. So at some point I thought I would press the button to active the display all the time.. but thats not happening (according to GSAM Battery Monitor).
I had all 4.2.x stock ROMS + stock Kernel and also with Franco Kernel. I always had this problem from time to time.
Signal is there, there is no significant battery drain from any app. The % of each app is normal and I also dont use any app more than usually. I don't have new apps.. everything is like always. Still my battery goes from 100% to 0% withint ~ 6 hours (30 mins SOT).
Any ideas? My battery is at 47-50 Celsius, the cores go offline as they are supposed to. I tried reboots in between e.g. in case an app is bugging. But actually all apps are as usual :/
Thanks
@edit: it also happens when the phone is on my table.. i just had it with 17% left on my table, didnt touch it.. after 30 mins it was off because the battery was empty. wtf ?
The biggest battery suckers are radios and the screen. I turn off wifi, GPS and BT whenever I'm not using them. Keep a short timeout for the screen.
Unfortunately, six hours doesn't sound too far off from normal if you've got things running. I'd go through an entire battery cycle watching a 2-hour 1080p movie. Overnight, my battery dropped about 15% while only bluetooth and GSM were on. The N4 isn't really known for good battery life :\
BT is off. In general my battery holds up one day without any problems. But sometimes it goes down within a few hours and I dont know why.
Possibly a scheduled background service? Maybe Google Sync is pushing a whole bunch of data periodically?

Hmm no not really. Also, it would happen every day or in some interval. Not just on random days?
besides that I dont use any syncing and also it would be shown in the GSAM Battery Monitor or general battery usage ?
I dare not say I'm a professional in battery saving, but I did break the 8 hour SOT on N4(minimum brightness of course).
Let's see, I only use 2G, because I only need internet for Whatsapp, and I greenify every single other apps.
You might undervolted too much according to your signature. -200mv might reduce heat but consume 1.2-1.5x more battery than normal voltage, its hard to explain, but its the truth, try -150 then -100.
Since you're on Franco, reduce the vibration a little, as for scheduler, I personally prefer Deadline on 2048. Governor definitely interactive, and freqs at 1.2Ghz. Because personally I dare-say at 1.2 Ghz you can run most apps almost instantly.
Like the second post said, Off wifi, GPS and bluetooth. Under settings > location settings> one is GPS and another is google location, off both. And you might still even have NFC on? No idea in this.
Download an app called build.prop editor or kernel tuner.
Modify build.prop a little. Add in pm.sleep_mode=1 and change the value of wifi.supplicant_scan_interval to 600 or 900.
Disable auto brightness and fix to something you like but below 50% .
I am not on -200 anymore.. -100 all the time
i also use greenify for nearly all my apps.
GPS, BT is turned off, Wifi normally too (tasker is doing that, depening on GSM antenna reachable or not).
The other tips are really nice but should affect the battery drain THAT much ?
Thanks !
As a little update:
It seems like this only happens at certain locations ?!
E.g. at work.. everything disabled (wifi, BT, gps, etc) .. even Tasker is disabled incase it was bugging -> about 10% for 30 minutes.
I have full connection bar to my carrier.. what the hell is that ? Battery temps are normal, same apps running as I had running when I was at home. I don't even use the phone but as soon as I get to work and my phone gets a carrier signal, the battery graph shows a rapid drop.
19:34 - 61%
20:03 - 54%
20:20 - 48%
20:54 - 38%
21:20 - 31%
Battery sitting at 37 Celsius... why.. why why ? :S
Alright now I know when my battery is crashing:
as soon as I turn off and I connect to my carrier. but why? Normally it should be exactly the other way. When WiFi is on and connect, the battery drain should become higher.
But as soon as I leave a WiFi, my phone gets hot and looses A LOT of battery very quickly.
Any ideas ? I have full signal.. but in any case.. I have the same signal as I also when while connected to Wifi.
e.g. at home with wifi - good battery life. but as soon as I turn the wifi off -> battery loss !
