[Q] Why is my battery life so awful?

I was at 100% battery at around 2:40pm today. I left and went to my brother's for Christmas lunch. Now, at 4pm, it's at 67%. All I did was Facebook (via the browser) and listen to some music (not the entire time). I frequently killed all the running apps, too.
I'm running Axura RC 2.5. I flashed it via Clockwork Recovery.

Then how do you manage backgrounded apps that you aren't using? They just drain the battery, no?

No, they don't. It's all related to how the Android OS manages applications. There's a ton of info about it - just google it. If you have battery draining issues, most of the time it's because you left something running that's constantly downloading/connecting to 3G or is doing something CPU intensive. Take the new Facebook app for example - if you use the chat function and you don't log out, it keeps you logged in and that will suck your battery dry. If 3G is spotty, you'll also have battery drain as the phone switches back and forth from edge to 3G, trying to connect.
I used a task killer when I first got my phone, because some moron at the AT&T store recommended it. My battery life got much better when I unloaded that crappy app.

I don't use FB chat, nor have I had unstable connections. I've had constant HDSPA all day. Could it be an issue with the ROM? I have WiFi, Bluetooth, & GPS turned off, as well as Brightness as low as it can go.

Hold down the home button and open task manager...
Also i noticed that using 3g on low signal kills the battery, try to use wifi...
You can also try assonance, i think its clocked 200 mhz less than axura, so you might perceive more battery, and it is as stable
Or try recalibrating the battery
Pd maybe it is an issue with the modem draining too much battery, you could try a different one, i bet if you dissable 3g your bat will improve a lot

Custom ROMs give you more speed, more power, more more more. That comes at a cost. You will have crappy battery life with some ROMs, and other ROMs may have better battery life.

For normal day to day work, EDGE should be fine. Switch from EDGE to 3G when u feel need more data transfer speed. This should help.

im at 11 hrs since my last charge...
currently at 30% battery
Depends on the Rom I guess... And ive done the usual... Checking email txts facebook and xda and on the phone all day.
Oh.. And I was taking pics all day too. Not bad for this phone.

I wanted to try Assonance, but whenever I tried flashing it via Clockword recovery, it froze at 'installing update..'. About to try Darkys 7.0.1.

Could it be a deffective battery? I used to get 7 hrs heavy use (web, games, music) with my original battery. I bought a backup battery (same thing, Samsung OEM 1500mh) and I am impressed I am now getting 12-18 hrs with heavy to moderate use. I guess I had a bad battery to beging with.

elektrisk,
has your battery life changed since you first flashed axura? if so, it is most likely due to an app you installed after flashing the rom. if your battery life has always been "awful" then you should consider flashing a different kernel, or another rom & kernel altogether

Why are people getting amazing battrry life?

I've seen a lot of people reporting unreasonably(for me) great battery
life , like three days WITH usage. Even for CM7 based ROMs, they( most people seen reporting) also get a day and half or two.
But for my personal experience, I have used my phone six months, and the best I got is 1.5 days WITH usage.
How do those people have those huge battery life? Or am I missing something?

They using gingerbread bootloader's, and only 2g network with off autosync

Do you use juice defender? If you tweak your phone right up, then don't use it you might get 3 days if you did correct first charge etc, but in reality most people charge their phone everyday as they use them, it is a smart phone...ie a computer, my laptop lasts 4 hours! T there is no point in having a smart phone if you don't hammer the pants of it!

i'm facing pretty low battery life problem also
back then i remember when my phone is on idle, every 5 min only consume about 5ma(according to battery monitor widget), but recently i have no idea why , idle will consume up to 80ma every 5 min, i have very little apps installed and most of it doesn't have push notification nor sync
Another main point, i'm on 3G instead of hsdpa, i expect much better battery life to be honest, i'm currently on Juwe's smart edition 5.3

check the processes
First of all check what processes are consuming more memory and CPU.
Try using "Usage Timeliness Free" app, which will show you which application is eating up your memory thus battery.
It has got option to terminate unwanted apps as well.
BO3527

Mine lasts about 7/8 hours at most with wifi turned off and some bloatware apps frozen aswell.
I've had the phone a year so I dont no if my battery is ready for the bin or if its something to do with flashing cf-root.
It runs out so quick I've got to make sure its on charge every night in case it dies and my alarm doesn't go off for work in the morning ha

I use that application + Taskiller

One major difference people overlook is how hard the radio works to get a signal. E.g. At home with WiFi and 3G on I lose about 10% battery overnight of the phone sitting idle. At work I lose closer to 45% for the for the same period. Naturally when I use the phone it'll be flat at the end of each day.

If i were u ill calibrate my phone.. when i first bought my galaxy i used to have the same issue as you... when i was listening to music for about an hour my battery used to dropped down by 20%.. but now it usually drops by 3%... i suggest to calibrate your phone, install a custom rom and kernel then install juice defender which toggles between 2g to 3g... ;] i get around 3 days now on a full charge on my galaxy... planning to get that 1650mah samsung galaxy armani battery for another 10% battery life on my sgs

[Q] LG Optimus Black Battery Life?

Hi There OB Users,
Just curious about your battery life.
Please post how long your battery can last.
What ROM and apps you using.
Mine can last roughly 20 hours on low usage (3G ON)
With Wifi ON, it's about 10 hours.
I'm using an app called "2X Battery" (can be found on market)
I'm running NOVA 4.5 ROM
Really appreciate it.

NOVA 4.5
Last three days I didn't use that much my phone so I could test how long does it go without charging.
Calling ~3min
WiFi - 5min
Camera - 10 photos
Winamp - 2h
Display was on about 1.5h
Other apps (no games) that don't use internet - 20min
At 5% I had to charge it for next day. So 95% = 2 days 18 hours. It would be 3 days if I didn't look what time is that often.
But for "normal" every day use, it's 1.5 days. I don't use internet because it's slow in my city (and it's optional for my plan). And at this moment I don't have WiFi router at home (I broke antenna).

Hey there.
here: NOVA v4.5
I use my phone a lot, like 2 hours of 3G network (lot of whatsapp, and quick web search). 3G aways ON
1 hour of calling
3 hours of music
The battery life is about 10 hours.
It would be great if i have at least a day, using it like i do.

Maybe undervolting?

hi u all!
i'm using cm7 for few days but its feel like my battery wasted so
last night i'm install 20b rooted rom then i install setcpu and advanced taskiller, i set them to battery save mode (its like close all app when screen of for taskkiller, and for set cpu, make my cpu %30 use when screen off) and i charced my phone it was %99 before the sleep. when i woke up i look at my phone and battery percent was %67, basicly i freak out!!! I JUST SLEEP and something use my battery %32
so, i delete setcpu and stop all activity of taskiller, but nothing change, battery keep going down :/
sorry for my terrible english

Check if you have apps which refreshes between intervals (or even push notifications) and avoid them.. the best solution is to disable Wi-fi and, if you are not a demanding person by others, switch to airplane mode while you sleep!
EDIT: If it doesn't work, just go to recovery and clear dalvik cache

Unfortunately, along with many of the downsides of CyanogenMOD, battery life is an absolute joke. I think you'd be lucky to get over 24h of usage on that ROM. I have no idea why, but it seems that it sucks the life from your phone WAY too quickly.
For those having battery life issues, I'm on Zeus 6.11o and i've increased my battery life by just:
Using a good governor (smartassv2) to control CPU usage when screen off.
Recharging from dead to 100% seems to increase battery life.
And after using playerpro for an hour, surfing the net, using NBA.tv, 3G always on, an hour or so of Kairosoft gaming and i'm currently at 73%.
So life's good under the hood.

wait for ics. im using L7 right now, the battery life is way better than gingerbread.

General Battery Usage Discussion

Hello, I'm starting this thread to actually discuss general battery usage patterns/ concerns. I figure this might be helpful for some people if not then..... =P
currently im using stock gb battery monitor to roughly monitor my battery usage, there is a mod to make the reading more accurate but i havent applied it yet...
Also... lets put up screen of the best battery life we've managed to get our phones here heee, would be fun to see =P
--
question is,
1) is it normal for mobile standby and phone idle to be ard 50% ish?
2) is it normal for my phone to stay in awake mode when i turn on the alarm

On Zeus v3n

Nice idea..
I charge my OB every night, and reboot after alarm in the morning. I dunno if it is from alarm or charging but if I don´t reboot the juice is gone in about 8 h. also battery usage app is frozen. I have this issue on every ROM, ( stock 2.3,CM7 from kang to about 60, marvell, zeus test v2.1, nova v8).
If i do the reboot in the morning the phone uses about 50% of the battery during the day (17 h). i use it for a few sms´s and calls, about an hour of websurf (wifi) and some facebook/ Xda usage..

I dunno, if in not mistaken, when you reboot it deletes your old battery stats bin but I'm still trying to understand how resetting a stat could make the battery last longer its what most battery calibration apps claim to do...
For me once a week I manually delete the stats thru cwm and yeah it does make the battery seem more resilient.....
And yeah I got the same again as my photo again, phone stays awake when I turn alarm on.... :/

Deleting batterystats.bin does nothing to callibrate your battery. It just stores info, like a logger. BatteryUsage retrieves the info to display it.

Something is causing a wakelock, what happened to you is not normal. Usually a reboot solves things like that, if it doesnt, then it will either be a rom bug or an app holding the wakelock. Use Better Battery Stats to find whats causing it.

thanks for the app recommendation found that my dialer is causing a portion of my wake lock..... and system too.... hmmmm
ok lets just say my dialer keeping my phone in a wake lock is caused by malware... would a clean install of a rom and manually reinstalling of apps w/o data get rid of the malware?
meanwhile... googling wakelocks =D

Hi, I have some experience with sudden huge battery drains and wakelocks etc. both on stock V20N and Zeus v3.2n. I did not figure out how/why it works but here are some things you can try. I did not have any huge battery drains anymore the last 24h! (on Zeus v3.2n, did not try on V20N stock)
- I have an IMAP email account installed with K9 mail and an ordinary hotmail account with the hotmail app. Both accounts are set on push and in this configuration the hotmail app causes my wifi to never go to sleep, causing increased battery drain. Removing the hotmail app solves the problem.
- automatic update of time and date settings can cause wakelock. Unchecking Settings > Date & time settings > Automatic might solve your problem. I read this somewhere on XDA.
- Use wireless networks to determine location might cause wakelocks as well. Unchecking Settings > Location & Security > Use wireless networks might solve your problem. Read this somewhere on XDA again.
As I said, I did all of this and my wakelock problem is gone for at least 24h! Now I already have 60h on one battery and still 43% left... I cannot remember the threads where I read about this but if needed I can search... Also I did not try yet whether any single thing actually caused my problem. I just killed all of it as I do not miss it I am happy. Keep me updated if you found out which one worked for you
Tip: the BetterBatteryStats app is written by somebody on the XDA forum, you can download the apk for free from some thread in XDA (search is your friend)

I think a day and a half is a good battery lifetime for the OB, if there is no app or something that drains the battery in a hard way.
I can manage to get this with the marvel rom, and my personal user-settings. Also i think every smartphone u can actually get needs to be charged around every 24 hours.

I also want to share my experience. I use the cm7 2.3 gb rom and the battery response is very bad. Battery completely dead in 18 hours. Then i switched to v20n german gb rom. It gives me better battery timing about 28 -30 hours on normal use. The i change the settings of account syncronization of gmail, hotmail, facebook etc to manual. Then there is a big difference in battery drainage. Now my battery consumed in 48 hours on normal use.

On android phones, if yours phone gives u 24 hours backup then it has good battery timing. Further you can increase the timing through the steps and trick mentioned by different peoples in this thread
Sent from my LG-P970 using XDA

Battery should last at least 18 hours on normal usage with 3G and sync with gmail , contacts and calendar. Sometimes you just turn off so many things to just make it home with some battery in it....

battery is mainly kernel related...
we need good kernels that all..

Thank you for the wakelock tips.
It seems that V20o is way better than all the other ROMS concerning battery, without any tweak. Maybe it can be further optimizet with tweaks.
A short comment: it is true that theoretically battery is kernel related issue, but in a real world high battery drain is usually caused by bad apps and other non-kernel related things.

using zeus v5.03 lite.
battery drains so much when the screen off. nearly 1 percent in every 2 minutes.
but it is ok when the screen off

Ok wasn't an sod but a random reboot, and it reset my apn settings twice when that happened

Since then, I have done maybe an hour of browsing on chrome, installed an app or 2, watch a short YouTube video, checked my email once, and played a game for 5 mins. I saw other people's battery stats and it says they have 20 plus hours of talk time? Mine says there is only 3 hours left. Is it possible I have a faulty battery? I'm also using juice defender and power save along with the brightness all the way down. I'm running android revolution hd with elemental kernel. I have the att version. Thanks in advance.

I find that based on my usage habits that I get terrible battery on Android Revolution v12. I always find myself going back to a rooted AT&T Sense build, and I'm able to pull 3 hours of screen-on time with 20% left.
Be sure to use a Wakelock Detector to pinpoint any rogue apps that are keeping your phone awake when it should be sleeping.
Also; be careful with those "Juice Defender"-type apps, Android has come a VERY long way in managing RAM, and resources since 2.2 (Froyo).
Report back with any findings

Don't mean to hijack the the thread but im having a rather peculiar issue 3g and wifi are eating away my battery like a percent for every 2-3 mins that also while only browsing web nothing else in the background can anyone help . Also im on stock rom , no root and s-off
P.S auto sync is off few apps have been disabled like (play store,facebook , google + and google search and few more)

jucie defender and power saver lol over kill i bet they are working against each other

I have about the same hours on stock rooted AT&T 1.26.502.12. Updating to stock rooted 2.24.401.1 has about the same hours, but it's only been about a week and I'm constantly flashing the new ElementalX kernels, so it hasn't settled.
Also, running at 1.2ghz and intellidemand/fiops.

I think my battery might just be bad

what? or do u mean WiFi

you should use GSAM or wakelock detector to view if something is killing your battery, I have a very VERY good battery life specially since I updated to 2.24 firmware, i guess you don't have root

Check the ss I posted of gsm, and I do have root. Also, what does it say in talk time left in gsm battery monitor when you have full battery?

My battery life was great until i flashed new firmware. i'm on ARHD ROM and it was great on 11.5, with 12 i started using nova launcher and now battery life isn't as good as it was previously. Have you experienced changes with your battery life while using some custom launchers? Or that's rather caused by new firmware/rom/radio/etc?

if i was you I will do the following
-update the **** out of your ONE (firmware and ROM)
but since it would be to laborious, I probably do the following:
1 Factory reset, in android (backup your things becaus it will be erased if you do a factory reset in android, or just dont do it!!!!!!!!) and in recovery (or only in recovery =.=
2 Install a custom rom that is near to a stock rom like ARHD (do it two times with full wipe)
3 with titanium backup remove (after do a backup) the htc bloatware crap that you dont use
4 with titanium backup remove the gapss that you could download from playstore, like youtube, gmail, and specially MAPS
5 GREENIFY all apps that you dont use commonly, you will be able to greenify apps like maps and youtube
6 DONT USE SEEDER OR ENTROPY MODS!!!
7 DONT USE battery saver apps
