Another battery moaning thread

I have read a load of threads relating to the battery life, but this is slightly different. I'm on jm1 official and have been for weeks, its was fine until a day ago, now I'm sitting at work, watching the battery percentage go down everytime i look at it, I'm now talking about now when I'm using 3g, just when phones idle.
I went to sleep last night and unplugged phone before I did, fully charged. Woke up and it was on 94%....
Really my question is, is there any way to find out what's using all my battery apart from the built in function which seems to only refresh every hour! I'm not looking for juice defender or such apps

Spare parts can give you, sometimes, some rough approximations. Really, if you started experiencing issues one day, you should try to remember what you downloaded most recently, it might be poorly coded and you should look to replace it with competing software.
Also, there are somethings you wouldn't want to intentionally or unintentionally leave running in the background. Use task manager (not ATK cuz it doesn't track "running" processes very well unless they've updated) to find out if anything is running. Even the marketplace will run in the background and not let your phone properly sleep.

Also, 6 percent seems about right. 2% for all services and 3g off, 6% for 3g? I'll have to look into it when I'm not on my phone. Especially if you dress your batteries by running them down to 0s%, this is bad to do to li-on batteries, I don't know how long it takes to feel the effects but short cycles are better for the batteries health.

Ok, 3g is never on at my house I can't get it there anyway.
The only reason I run it down to 0% is because I'm using my phone and it doesn't last, its stupid to say use it in low cycles because then I'm really only getting 20% battery life anyway...
I have advanced task manager but don't really use it from what ive read I shouldn't have to. And I had thought about the recent apps I've installed and I have installed nothing much new apart from angry birds
Just not happy with the noticeable change in the space of a few days.

If consumers keep "living" with things then they deserve the crap they get. As a consumer, you have the right to be heard so make sure the people you're giving your hard earned cash to is taking your feedback and providing products and services for YOUR needs, not the company's needs.
I'm loosing 10% every night too. It's a joke and I'm hoping the updates will improve it somewhat.

ye i know. but funny thing is, it's rather random. with the same settings and nothing changed at all. sometimes overnight, it drops close to none. and some nights, it drops 10%.
i've lost 10% over 4 hours today with no usage (idle) so lol. i'm glad i'm at least getting 2 days worth of usage.
let's hope this famous froyo does something. sometime soon...

Make sure all applications are dead (ie. use samsung task manager).
Turn off apn (so that you can guarantee no apps are using data).
If you do those two things, I'm sure you won't lose more than 5% overnight.
Personally, if I do that, I don't lose more than 1% overnight.

maybe it's due to over-flashing and all. de-calibrates the battery or whatever. either way, meh.
i've probably only got this calender widget refreshing itself every 12 hours to update the day's events and my Google account on active sync. maybe some applications screwing up somewhere.
to point out, a fresh flash always gave me no problems with battery draining. (after "re-calibrating")

just updated my phone to the TEST firmware JPJG8 which is currently the latest one available thru kies which includes arabic, and have seen no changes from the original firmware the phone came with ( Originally bought from Abu Dhabi with whatever firmware that had the android market not being available )
toying with juice defender for 2-3 days my SGS laged like hell even with the RyanZ lag fix OCLF from the market and it said that i saved 1.5% more juice tho i didnt see any diff with batt, it still drained fast (full charge overnight + extra charge with phone off on my way from home to work and starting @ 100% once leaving my car and ending @ 30-20% in the afternoon about 4-5pm, need to charge a little more if i wanted it to last till 10pm T_T )
deleted it today and thought why not simply use the extended control widgets to disable the connection when the screen was off + switch off the auto sync, like how the program did but manually and amazingly batt life felt like a big nasty battery i felt the diff immediatly.
kept the program juice plotter to see how steep the batt was used to compare the results.
1. keeping my phone on 2g almost all the time except for when i need to browse the net/use msn on phone - i do use facebook/twit and i might be missing the fast notifications but 2g is good with those 2 and battery life sure is extended as i can see.
2. closing the apn when locking the phone and bringing it up when screen is on is a great idea and u can almost instantly tell ur battery life is better
3. keeping screen off as much as possible helped my batt too tho i dont like it but it works.
really noticed a diff in battery usage today so im currently backing up the phone and after a fresh format/restore session will apply root and OCLF and keep you all posted on how long the battery lasts using this method
will test for 2-3 days before reporting again.
Current Battery stat killers are
1.loads of calls
2.display due to a large amount of sms's
see you again after my test in a couple of days

I don't think jg8's a test though unless it's a new rev by kies. used it a month back, pretty awesome but I've switched.
heading to bed now, shall see what happens tonight! such adventure and excitement every night.

jg8 isn't a new rev, it was out for a while and cant be found without using the ctrl+alt+u+p (and if that = test then its not an official release) at the firmware update in kies, its a middle east version with arabic support.
ok impressions on how things went.......
voice calls = 49% with 1H 13M 23Sec
Display = 35% with 5H 0M 9Sec
Cell standby = 7% with 16H 58M 44Sec
Phone idle = 4% with 11H 58M 34Sec
Android System = 3% with 42M 30Sec on CPU Usage and just 20Sec on CPU foreground
batt did last a full day for me i guess ending @ 6% when i got home
but what use is trying to save the batt life when i hardly use the phone
lets say i browsed the net for a 30min-1hour session, watched a few youtube video's/even downloaded video's for that matter or played a game or 2 for like 30 mins to an hour
ofcourse the display will be the major batt sucker by doing this and i doubt it would last an afternoon if i did so in the morning/noon time
I guess my only solution would be an extra batt or 2 for that matter if i really wanna show-off the phone and enjoy it fully for a full day. But the problem would be charging them all without a phone stand with extra batt charger
Anyways, does the batt last a full day for me , yes it does
am i satisfied doing what i did to make the batt last , N O

I got sick of my battery running out at around 3pm at work every day so I've now bought 2 extra batteries and an external charger from spider-foot.com

Well, greetings to all.
I just wanted to share my experience regarding the battery issue.
As I purchased the phone some 12 days ago, my experience is short, but somewhat effective.
First couple of days the battery lasted for app. 24h, with lots of usage (wi-fi surfing, lots of applications installation, calls, games, music, etc.). Then, I installed some "battery-indicator-related app", fully charged battery and used the phone for 15 minutes or so and went to sleep. In the morning my battery was at 80% !(it was on stand-by the whole night), and till 2pm it was at 15%, without using the phone at all.
Battery usage stated 64% "cell standby". I thought - what the .... ?
Than I did the next thing.
Uninstalled that crappy app, installed another one (similar, but other manufacturer),turned off the phone, fully charged it, turned it on, checked that wi-fi and BT are off, turned off 3G and syncs and updates, set brightness to lowest, installed black wallpaper, used task killer to kill all unwanted apps, and decided to see for how long will battery last with that settings and very little usage (couple of calls, sms and some sudoku playing).
The result:
4 days, 18 hours - since unplugged. Battery at 39%.

@ some of your replies
overflashing - ive only flashed once.
be lucky it only drops 6% when totally idle - the whole point in writing this thread was because ive previous lost 0%! when idle for hours and hours...
I have background data off (which i dont want to have to do) i have an APN switch which i use sometimes, but tbh its tedious and i shouldnt have to do this.
as far as im concerned, when i idle the phone, it shouldnt do ANYTHING

Battery only last me 7 hours :(

I have a nexus one running stock and I cant get through a day of battery power. if im lucky maybe it can last me 8hrs is it common? I have wifi off bluetooth off I dont have live wallpapers or widgets running. Also seems like either tmo or htc devices dont get good reception my hd2 & N1 always switch from 3g to edge like every minute sucks.

Mine can last 8 hours with heavy usage, how old is your Nexus One?
Pay attention to running services and processes, use a task killer to find out what applications are running automatically and consuming much CPU.

I bought it on ebay the user said he had it for less than 3 months so im assuming maybe 4 months old. I have only emails running auto 2 are normal 1 exchange for work. I maybe use 30 min of calling few emails and maybe 50 sms and 1 hour to 2 of web browsing and also 2 hours of music. I was thinking of under clocking the phone to 600 to see if it gets better.

Get memory optimizer from market and set it to moderate settings, should help.

Check if you have the stock battery. I have 2 extra batteries I've bought off eBay, one of them can last me between 10-14 hours moderate usage like yourself, and the other about 7-10 hours (sucks!). The battery that came with my phone lasts between 24-36 hours (I know, huge range but it really depends on how I use it.)

I tried that battery back in April and found it no better than the stock battery, even after conditioning. It's sat in my spares box somewhere and I kept using stock.
My stock battery's at 68% after 12 hours today (not heavy usage). My heaviest usage is on work days and I have desktop docks at home and work to top up the charge where necessary.

Hopefully gingerbread update makes it better I hate carrying batteries around. Maybe I should just buy a normal htc battery

What apps top your battery status list for usage?
- -
Monkey see, monkey do.

Also, try to take the SD out and test the phone for a day without external memory.
You might have a corrupt multimedia file on the SD card, happened to me not a week ago. The battery would last about 8-10 h, while it usually lasts for the whole day with about a third to spare at the end.
If that doesn't help, then go to the market, and get "Usage Timelines Free". It's an app that shows recent CPU usage in the notification area. When you notice high usage, select the notification and see what app is hogging the system. You might want to do Preferences->Start at system startup, and also Sort->CPU Usage before that happens.
The indication of something not being right with multimedia files is an abnormal activity of Android System which you could also notice at the end of the day in android's Settings->About phone->Battery use. This menu logs battery usage since last unplugged, so remember to check before you plug in the phone. About 10 to 20 minutes of "CPU total" for 8 hours since unplugged, is a normal amount of usage for Android System, alot above this value is suspicious.
There, some pointers. Took me a while to figure this out.

Thanks everyone for the pointer and your replies first thing tomorrow I will try to see how much it can last me without plugging the phone to a charger see if it was just me not having the right set up. Yeah cpu usage seems a bit tricky to figure out I also notice calendar was running 20MB which is weird because I dont sync my calendar any more.

You can also check out SetCPU (on the market, or the nag-ware version on XDA) - I have mine set to ondemand for normal use, and a profile to clock it down to ~400Mhz when the screen is off. Makes a huge difference in battery life and you can tweak it to your needs.

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.

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.

Battery not so good

I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.

most smartphones ned to be charged every day, what battery life are you expecting to get ?

battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.

Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.

+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.

try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.

Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...

My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100
Checks email every 5 mins
Using a live wallpaper
Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on
Battery Widget
Fancy Widget
ESPN scoreboard ticker widget refreshes
Twitter running all day

4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.

Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE

I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.

Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Thank you. I will give that a try.
Badass, got to love that name....

Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks

What about your connections? Do you have 3G/wifi enabled at all times?

calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now

Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal

Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone

Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher

Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

if calibrate doesnt work, hardware faulty, change ur battery mate.

About 2 hours later that I fully charged, here are some ss
Just used whatsapp and opera in this time
I was thinking in change my kernel, currently I'm using semaphore 3.0 with CM10.2, is Latrop or Mackay better in battery life ?
I think its my last shot ... I'll provide a new battery next week, but i've heard some people with batt probs that even with new batt the problem persists :crying:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Using bout 2 days ... but i didnt knew about ' calibrate '. Good to know that
Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage
