[Q] Poor battery life.. being reading a lot of threads but..

I have been reading of a lot of threads about how to save battery life..
here's what I done:
1. gps off
2. auto kill w/ advanced task killer
3. screen brightness at low
4. sleep screen after 15 seconds
I have got my desire for a few months and battery life has been bugging me. I understand that modern big touchscreen will drain the battery as compared to normal phones. Using a custom rooted rom atm.
I unplugged the phone at 12:00 with data on (push, auto-sync, etc), when i woke up at 7:00, I'm getting 73% of battery life. Charged it to full again and unplugged it at 8:30. My phone the phone shutdown by itself at 21:30. It's a little bit more than 13 hours of battery.
Is it me or everyone else is getting the same number? I just installed setcpu and see how it goes.. please tell me if there's any other way to preserve more battery!

I think it partly depends on which ROM you are using. I am currently using a new ROM (which I LOVE) but I've noticed that my battery life has decreased quite a bit. It can be kind of a trade off. I love the ROM so much that I'm not going to change it but it works ok for me because most of the time, I am somewhere where I can charge my phone if necessary.
Just found this thread which might help. http://forum.xda-developers.com/showthread.php?t=755903&highlight=battery+usage I'm going to try it and see if it helps.

- ROM?
- Display on time?
- Cell/WiFi on time?
- Chrome2Phone (or similar) running?
- Any battery widgets running?
- Any social networking apps/widgets running?

..overall the battery lifetime is not as good as we would like it - but its a general smart phone problem - anyway I charge my device once per day...who cares?

What's the average battery life with cellular data on?

My battery life is also quite shocking, also lasts for approximatly 13 hours under normal use, but if it is in standby then I'd say it lasts for 20 hours.
under normal use:
no 3/2g mode, just wifi
leedroid 2.2a
occasional games
occasional call (like 1 in 10 hours)
1~2 messages
btw you can find display on time in 設定->關於手機->電池->喚醒時間

and your current battery status?
(sorry I type faster in Eng XD been away from TW for like 9 years now...wanna go back TT)

Do a full typical usage discharge from full to near off and see what the battery stats in that section read for Display, Cell, Phone idle and anything other (tap each one for hours and percentage).

I'm not familiar with the app but I am with FB and such and their widgets. Any app/widget polling at high frequencies like per second or per minute produces a high additional average drain which cuts runtimes, especially standby efficiency. That includes monitoring apps.
Do you have the battery widget chosen in Extended Controls, or the auto-brightness?
What's the average battery life with cellular data on?

I can't say because supposedly, mine is well above average. It depends critically on usage and setup, too. 24-42hours with 5-9h display on and WiFi/2G always on is quite the norm on mine. Put to sleep (standby), it doesn't drop 1% until 6-9 hours. There's many many threads every week about this now. And I have many updating widgets and auto syncs running, just nothing to do with social networking since I've completely deleted from my phone.

Sorta new to the forum.
Just got me a HTC Desire. Rooted running CM6.0.2
If i baby it, i get maybe 6am-2pm. Heavy use, its done before noon. Ouch
Standby is ok, i left it off the charger last night and I lost 25% over 10.5hrs.
Ive got 1 twitter app on a 5min refresh. Weather is on 1hr. Screeen is down around 15% brightness. setcpu is on 245min, 998max, scaling on demand an a screen off profile of 245.
I have no idea what more I can do to get more then half a day out of it without just not using it lol.
Im pretty new to Android and all this rooting/rom stuff so maybe Ive got something screwy. I also tried a second battery from a friend, no change.

set that friends widget to longer than 5 mins and the weather widget to every 3 or 6 hours. i bet you that will get you alot more time.

Made the switch but cant see it making that much of a change.
Any other suggestions?

[Q] What's draining the battery so quickly? :S

My phone loses battery at a phenomenal rate. Overnight it goes from 100% to 75%, then this morning it went from 70% at 9:00 to 10% at 12:00, what's draining it so badly, in both cases it's been inactive.

Check if your phone keeps syncing with your accounts.
That is one area which drains the battery.

I left Wi-Fi off so it wouldn't be that

Battery is disaster... I have same problems.

Could be the /INIT bug, which will go away if you enable USB debugging.
Press Menu then:
Settings > Applications > Development > USB Debugging (tick it)
Also, check your sync settings as iAltair suggested.
Press Menu then:
Settings > Accounts & Sync
Turn off anything you don't use and for the stuff you do use set a reasonable sync time like 3hrs.
Don't forget to check calendar sync settings too as when I first set up my phone it added calendars I didn't want to use. To do so, open the calendar and press menu.
You can also check battery usage but I can't remember how since I used BetterCut to create a homescreen shortcut for it. It's in the settings somewhere though!

Could also be the problem with HTC Sense sync. Try to disable that completely. For me that was the problem which for some reason made the CPU work at nearly 100% constantly. After I disabled that my battery lasts 18-20 hours during heavy use.

It will still sync over wi-fi which will drain battery, also wi-fi itself will drain battery if left on

I have this problem when I do OTA 1.72. Right now I'm still in1.72, but with root s.cid,etc...etc..etc... and I see and high use of battery. Read a couple oft thread about and:
disable all sync (htc,google,weather,news) but it's on for market.
On and OFF usb debug
So try everythig.
Today I found the setting/phone info/battey/battery usage.
ALL is fine, all IS under 10% except DISPLAY, it's run from 55 to 69% !?!?!? Possible?
Possible tweak?
How much % your dispaly use?
ROM revolution 2.0.4
Andorid 2.2.1 - 1.72
kernel....haven't the phone in my hand, it's charging at 1st floor.

also check email setting as the on-peak(checks every 15mins) and off-peak(can't remember think every hour) but on-peak starts at 8am-8pm this is by default. depending how many emails you have, this could drain battery quite a bit too.
and doesn't matter if you have wifi and moblie data off the apps will still try an sync.

Do nothing except install currentwidget to log use of battery, for report here.
From 02.00pm to 4.14pm, display use from 30% to 42% .

Display uses a lot of battery. It is Big. My usually uses about 50%. Currently it is at 60%. I use screen display brightness at auto.
Regards, Ales

I set bright to auto. I think it isn't the problem. Sometime it's 60, or45, and also 33% of battery use. I charge phone all night. Pickup at 07.45, i disable also email check. I drain about 10% of battery for hour. After 3h39m I'm at 61%. During this time the phone was standby for 90% of the time.

Now chargin, then go out again. Brigthness are now set to 25%.

i checked the battery status and the "android OS" is always at the top, is this just my one or does anyone else have this problem?

what would be the best kernal for me to have ?

my battery drains like a bugatti veyron doing 252mph constantly
so what would you advise . is the kernal i have now the best or should i change .. i dont want to reall lose much performance on what i have now but would like the battery to maybe improve if possible ...
from full charge taking plug out searching market for 2 mins the battery drains 5-8% in matter of mins
and i have only had the phone a week

With that kind of drains the problems the kernel won't change that much. There is probably a app that causes the battery drain so looking in to that will have more effect. Also the brightness/screen on is the biggest drain and kernel won't do much about that.
You said that you have the phone a week, the battery needs some time to reach it's full potential and you probably use the phone a lot because it's new. So use the phone normally for another week, after that week let the phone drain until it shuts itself off, leaf it off and charge it till it's full. (there is a different calibration method but this always worked for me)

What do you have now? Stock or rooted?
Sent from my HTC Desire using XDA App

First of all, I would assume that you don't use the phone non-stop (it would be justified to lose power in a few hours if you're on it non-stop).
I recently had issues with power consumption as well. What I did was:
1) check the built in battery monitor: menu-settings-about phone-battery-battery use. The bad thing about this monitor is that it does not differentiate well the apps consuming power, but you can still see if there's something wrong, as the most consumption should come normally from the screen and voice calls. For me, the most consumption was made by com.htc.bg, which, if I let the monitor on for a few seconds, would transform in the calendar app. Weird stuff. I unchecked the calednar auto sync from menu-settings-accounts and sync. It may have slowed the power loss down, but not significantly. I noticed a significant loss of battery by WiFi. I realized, I needed more information so:
2) I installed an app called 'Power Tutor'. What it does is, it calculates which apps consumes power, and it shows you in percentages. After install, you need to start the 'power profiler'. It will appear in your notification bar. If you let it run, after a few hours, you can see in "view application power usage" who is using power. That's how I discovered that my winamp app was really off the charts using power like crazy. So I went in the winamp settings, and I unchecked some options that could have determined this power consumption, like wireless sync, automatic mount as USB drive, etc. There was actually an option that was overriding the wifi power management, stating that the wifi does not stop after 180 seconds of standby. Basically, if you have wifi on, and you stop using the phone for 3 minutes, the phone automatically turns off the wifi. This was not happening any more, due to winamp. So I unchecked all those options, and voila. It worked, I have now normal battery life.
Good luck!

be aware of a couple of things
1. battery drain for the 1st few weeks are high because of a couple of factors, the battery "learns" and gets conditioned over a period of time (doesnt use the old 16hr charge process). its a new device for you so its a novelty, you probably mess about with it with the screen on more than you think.
2. there is a configuration within HTC's builds and in the memory chip of the battery to stop over charging. the device will charge to 100 and then slowly deplete to 90% while still saying full on the phone. as soon as you disconnect it recalibrates to the correct value which is anywhere between 90% and 100% depending at which part of the cycle you catch it

Some other tips to increase battery life, from a friend of mine in the Romanian forum:
1) use the app watchdog, it will warn you when an app is using too much of the processor and will ask you if you want to close it.
2) juice defender with the paid add-on 'ultimate juice' - with the correct settings... it's amazing.
3) Dial *#*#4636#*#* - phone information-network type: select gsm auto prl. The phone will stay on 3G when it has good signal, and switch to 2G when it doesnt, saving battery
4) Change the wallpaper to a static one, not a live one.
5) Go to menu-settings-accounts and sync and increase sync intervals for weather, news, or even set them to sync manually when you choose.

i will try and answer everything at once ..
ok my screen is on 13% brightness
i hardly ever use my phone , the only real use was to root , s-off, put ROM ETC ON
I reply to about 50 texts ish per day and search the market for literally 1-2 mins to see what new apps are in
i dont play games or anything
the thing the battery uses most is the screen and as i say i have it on monochrome theme with 13% brightness, there is nothing synced , i check automatically for email etc .. actually beautiful widgets is set to auto update every 4 hours
i never use wifi as i have a 3gb download/data usage, i dont use gps ...well i do but i have had no need to .. thats about all i can tell ya
rastaman the pt2 is a bit weird it should stay at 100 if just taken out of charge

I calibrated the battery and that made no difference.

[Q] Battery issue on Wildfire S

Hi,
after running for 15 hours, one phone call for 2 min, and about 8 sms
and nothing more still remain 45% from 100%.
is that normal or it is something wrong?
wifi, gps, and bluetooth are off, and not many apps are working in background.
no livebackground or something else.
it seems to me, it is very less for such a phone, or I am wrong?
or are there some settings, which need to set to have a longer battery live?
thanks

Hi,

I too am seeing that the dialler is using 97% of battery with only one short call made. However, I have so far and still counting got 3d 18h out of my first battery charge. (This is a new phone) This is with everything turned off mind you as I wanted to see the best time achievable with only phone functions active. Once the battery is run down I will re-charge and turn internet on etc.
It's funny that you too have "97%"??

very strange.
could someone post a normal state, how it supposed to be?
thanks

Hey i think you people don't know how the battery use calculate the battery usage in Android.
This is how it calculate
Suppose you had power on the phone then and you are using 3 apps like
1.dialer
2.wifi
3.display
then from above 3 which is the most used app the battery usage will give it more percentage.(But you will not see any 97 % if you are using 5-6 activities)The more the number of apps the less the percentage of each Activity.
The region why you are seeing 97% on battery usage about dialer is that you are using only dialer nothing else.If You use use gallary,wifi,bluetooth,calls,maps etc all together then battery usage will show you 15 to 20 % in each.
To increase battery life calibrate you battery.(let the battery discharge once and recharge it without power on and without any break)
In this forum i had seen that some are geting 4 days of battery with moderate usage and some getting only 1 day.You Had not calibrated your battery.Every Android mobile needs battery calibration atleast once in 1 month.

hi shreyasharusia
yesterday I made a reset, and I calibrate the phone.
Now I have following situation:
Dialer 41%
Cell Standby 29%
Phone Idle 28%
display 2%
android system 2%
Today I made just on call for 2 min, and I have 98%
do you think somthing is wrong with it?
thanks

could be a bug with the sense causing the battery life to be short. I usually let my phone discharge every day before I charge it for the next day. As I am usually using my phone every day the battery usually lats a day at the maximum this is usually because i am always listening to music or texting people.

now I have again this situation.
I did nothing with the phone. just one call for 2 min and 2 text, thats it.
dialer 95%
cell standby 3%
phone idle 3%
so then it is wrong to have the dialer on 95% right?

that's not possible.Battery use limits to 100 % not 101%. 95+3+3 = 101.And in your first post 41+29+28+2+2 = 102.How it can be possible .
Also check is your connection is 3g or 2g.You get your battery life according to it.

.... I know, but it is fact
I was surprised too....)
I will search for a screenshot tool, and I will post it soon....
by the way, I check it with Advanced Task Manager, maybe this tool is wrong?
I use 2G only. I wouldn't be suprised if bluetooth and wlan would be on, and after a work day the battery is empty, but for one call and 2 text?
as for now, the Task Manager and a File Manager is installed, the rest is all on default.

Hi, im new htc wildfire s user, barely a week. Before my battery usage showed lots of things but now theres Dialer 97%, Cell Standby 2 %, and Phone idle 2 %. Whats going on :S? Im releaved that im not the only one. Can somebody please help me im begging

My girlfriend's wildfire s' battery life is really bad. At first it was like 16 hours, but that was when it was in a really heavy use. Now it lasts only for about 12 hours with very minimal use: a couple sms' and little calling. In fact the usage doesn't even affect the battery life, as it drains at a constant rate. The values are _always_ the same: Dialer takes 49%, Android system 49%, Idle 2% It doesn't even show how much the display is using!

[SOLVED] this battery issue
Hello everyone who is experiencing really massive battery drain on wildfire S.
Symptoms:
1. you own wildfire S
2. in battery stats the "dialer" is on top (eg. 97%)
3. you have made a call recently
4. experiencing battery drain about 30-50% per hour.
Cause:
Maybe it really surprises you (or your girlfriend), but you are most probably making a phone call. The new wildfire's dialer is just a bit crappy. When you dial a number and then want to hang up, you have to do it by correct button (the red "hang-up" button). There is also a possibility to "terminate the call" by pressing the "back" button on the bottom, but in this case your call is not terminated at all, but dialer is running now in the background. The nice example is when you are calling a buddy and then you hang-up(using back button) after you realized that you are being redirected to voicemail. By doing this you are still talking to a voicemail for a period of time until the call is terminated automatically by that particular carrier.
Solution:
Use the red button to terminate the phone call. Check the logs and you will see if this is your case.
If you find this post helping to you, just say "Thanks" ---->

does anyone know the pin diagram for the battery?
I just want to know how the android takes the data from the battery.

For users experiencing massive battery drain after making a call and the infamous "Dialer" process is showing up in the battery, you need to follow the greatest battery saving top found in this thread. impreza_rs posted this solution taken from the HTC website:
"connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once"
I do this process every time I flash a new rom on my device and it works flawlessly. A little tedious, but you only have to do this once and you are good to go.

Ways to save battery on a rooted G2/Desire Z?

I have a rooted G2/Desire Z. What are some ways that I could save battery? It seems it takes only a few hours for it to reach 50%. Granted the phone is now >2 years old and the battery is probably aging. I've done all the basics such as screen brightness set to auto, dim after 30 seconds, etc. etc. etc. What more could I do?
Alternatively, are there any apps that can control the phone/cpu to work a certain way to save battery life?
Thanks

Easiest way:
Uninstall fabebook app, flash a sense rom where you can access most fb functions without the app.
For real, my battery life went from about 10% an hour to 4% an hour on average.

Honestly, way number 1 is to get a new battery. Old batteries just start to drain much faster as they get older. Pick up an Evo Design 4G stock battery for a nice boost.
2. Turn brightness off auto and put it as low as you can handle. Keep a brightness slider on your notification bar for those situations you need to turn it up quickly.
3.Turn everything that "syncs" off of push and set it for 1hour+ intervals if possible.
I have had great standby time using the OC daemon that is packaged with the mimicry ROM as well.

There is this trick that helps. On a monthly bases drain the battery and re-charge with the phone on ie also a good Rom an a good radio version like .19 will keep your battery good don't use lots of ram manager apps and bettery saver apps the run backgroung processes that drain your battery fast

^This (regards to #1), and working batteries are rather cheap, the fat one I got (3500mAh) was 9$, but you can easily get a stock replacement of the 1300-1500 range to fit with the default battery cover.
Far as tips, rooted or not:
1) Screen to automatic, or avoid 'full brightness'. Your screen consumes the most of your battery, automatic or lower brightness can improve the life significantly. This is the big one as your screen will typically be 80-90% of your battery life.
2) If you are near wifi often, System Setting -> Wifi -> Advanced (via menu) -> Sleep profile to always on. This will set it so that the wifi connectivity is always on even with the screen off. A connected good wifi connection uses far less battery than your 2G/3G data constantly searching for a good or better data connectivity. Simply turn off wifi completely when not in an area with wifi (or if you're driving around).
3) Avoid unnecessary applications. Don't use twitter? Freeze/Disable the application under manage app or under Titanium Backup (generally it's not good to 'uninstall' an application completely if it came with the rom).
4) SetCPU with profiles is one way to do it, unless your rom comes with a CPU Daemon already (ie: mimicry with virtuous OC Daemon), When setting a "screen off" profile, try not to go below 768mhz for the maximum, as going with 384mhz for example may be too slow for the phone to effectively wake up when a call or notification comes in.
5) You can use an app such as Tasker (not to be confused with task killer). Where you can assign automatic tasks, such as automatically setting Radio to 2G when connected to wifi (some roms like AOKP do this automatically under power control), or other tasks depending on the circumstances.
6) The first time you get a new battery, make sure you leave it on the charger for a good 5-6 hours so that it accurately 'tops off', the phone won't know accurately what's 100% and what's 0% until it has been fully charged (least 6 hours minimum), and fully drained, after which it'll more accurately report your battery % as it's used and will have more accurate usage stats.
7) If you're a T-Mobile subscriber, consider the 26.13.04.19 radio as well as the T-Mobile Wifi calling app, wifi uses less power in the long run than your radio via cell towers. If you'll be in a location that has wifi often you will benefit from this over not using Wifi Calling. (The main downside is you cannot currently send/receive MMS over wifi calling, but Calls and SMS[txt] work fine). Even if you don't use the wifi calling app, the 26.13.04.19 radio provides better battery life over the older one.

Course it helps to clear battery stats before performing this task so that the OS/Battery-Stats records the new maximum and minimum values of the battery. Though you don't need to do it monthly, I would say closer to 6 months would be appropiate if you don't want to make a monthly habit of it.
You mainly only do this on account of battery aging (over time the battery will not hold as much charge as it once did), You normally know if you need to do this task again if it appears to be on 98% or 99% forever never reaching 100%, meaning that the battery is no longer able to hold the juice to provide the former-maximum mV value, re-doing the battery stats simply makes the new maximum marked as 100%.
PS: Strip419, on an off-topic note, I tend not to 'thank' people who ask/beg for it. If your post is worthy of thanks, they'll be clicked on their own accord.

OK MAN I'LL KEEP THAT IN MIND

Best rom I've ever used for battery life is EliteMod. That rom did something crazy, cause my phone lasted for days before it need charging, and I use facebook and all that good stuff. It's not as fast as other roms, but battery life is certainly the best on that rom.
Also yea, before with stock battery my phone would last a day at best, and now I have a 1800 battery that makes it last for 2 days easy. So if your phone is at least 2 years old, get a new battery. They're dirt cheap on Ebay or Amazon. The phone comes with a 1300 stock.

simply change for normal use 2G instead of 3G.

A couple of questions--I'm using EliteMod CM7

2) If you are near wifi often, System Setting -> Wifi -> Advanced (via menu) -> Sleep profile to always on. This will set it so that the wifi connectivity is always on even with the screen off. A connected good wifi connection uses far less battery than your 2G/3G data constantly searching for a good or better data connectivity. Simply turn off wifi completely when not in an area with wifi (or if you're driving around).

My Advanced settings don't look quite like yours, alas. (I'm using EliteMod cm7.) The section is entitled "Wi-Fi sleep policy, Specify when to switch from Wi-Fi to mobile data" and the only options are " When screen turns off," "Never when plugged in," and just plain "Never." I assume that the "Never" option, that is, never switch from Wi-Fi to mobile data, is what you mean...that is in any event the default (set by this particular ROM?)
But my problem goes beyond not quite understanding the semantics of "Never" (off?) vs. "Always on." What I continue to find odd is that my highest battery usages, at least according to Battery Monitor Widget, are never the screen at all; rather they are cell standby, Wi-Fi, phone idle and Android System...Display is down at 6% just now, for example (and I've been up for hours, have read the news on the phone, emailed, texted, etc. This is on EliteMod only, btw, I used Flinny's latest build (.94?) for a few days recently, and while battery usage was worse, at least the display was at the top of the list, where it (presumably?) belonged.
I have all the latest and greatest tweaks from the the forums (for cm7 roms, that is) the .19 radio and sd-ext and all ext4 partitions. Am running the generic 3500mah "fat boy" battery...drained and refilled several times, all according to instructions...mine only shows maybe, umm, 2300 or so mah, but that's not the issue for just now...it's why my usage looks so odd, and how to fix it, if need be.
thanks to all,
p-d
oh yeah. I have long used (pre-rooting) Lookout and Pouzerate's Green Power free apps...have now turned them off (well, uninstalled them, in fact) just to see if, indeed, battery helper apps make things worse, running in the background... any thoughts on that topic would be welcome as well.
