Battery life sucks

I've had my battery replaced, I've wiped my phone from ROMs, and I've used aggressive SetCPU profiles...
What is annoying though is setCPU recently updated and I decided to see how my phone ran without it.. battery life is horrific with a simple UV kernel.. Why is this?
I mean I take my phone off the charger at 11am and by 10pm its less than 15% remaining. I now have a second battery from HTC after a warranty replacement but I saw very little change. I have a task manager that auto kills everything now which helps but it is annoying since I lost my car charger my phone is discharging all day.
Is this normal and I'm just freaking out or do I have a real problem?
Running Kang-o-rama ROM with ~20 apps

I know 3 things about the N1 battery:
1) it took a couple of weeks for my battery life to max. Lithium batteries need a break-in period. They have no memory, and the recommended approach of not using the phone until it's full charged is bunk. Just use it normally and it will work as it should.
2) Switching between 2G and 3G constantly murders the battery, 4 hours and you're dead. If you're going to be in an area like that for a while, force it to one or the other.
3) Watch your apps. If your phone is acting even slightly sluggish it's CPU is maxed which is killing your battery. Slowly swipe between homescreen pages, it should be silky smooth without any stutter. Try and track down which one it is and either install/reinstall (which fixed an issue with Better Keyboard for me) or completely uninstall if you can't fix it. Check for apps that ping the network too often, or ones that start up on their own.
I will add that the built-in 2.1 battery usage tracker is not 100% accurate. In my Better Keyboard example, Android said it was the screen using all the juice, not the app. Might have to do with video graphics drivers, I really don't know. Point is, after uninstall/reinstall my screen used 55% of my battery instead of 75%, so don't trust it.

Are you kidding? You're running your N1 for nearly 12hours and you STILL have 15% juice left?!?
Search the forums, 12hrs and still having juice left would be considered excellent to many.
...Then again, you haven't mentioned what your usage is like. If we were talking about your phone being in sleep mode for most of those 12hrs with just an occasional call or 2 that only lasted very briefly...Then that's a different story.

Have a look at Juicedefender, it will limit your internet access to 1Min on every 15Mins when the phone is asleep/screen is off. Does wonders for battery life

Reasonable battery life expectations after Rooting

So sorry for adding to the battery life threads, but I'm pretty frustrated.
I've seen people posting screen shots with 18 hours uptime, 7 hours wake time and 50% battery on custom roms. I've seen people getting about 24 hours on a single charge.
I've had my evo 2 weeks now, and I've tried about 3 different ROMS and 4 or 5 different Kernels all of which promised LONG battery life. I'm currently running BakedSnack 1.7 with Kernel #5. My phone has been on 10 hours, 2 hours of wake time and it has only 35% left. Couple of short phone calls, 10 mins Pandora and a bit of browsing and texting here and there. I was expecting more after rooting, yet it seems almost the same as it was before I rooted.
Am I expecting too much ?
I've gone through the full discharge/recharge cycle about 4 times so far. Bad battery perhaps ?

will the phone charge get you through a day say 10 hour work day ( includes travel time )
imho your expecting to much with 10 hours in to your charge and still have 35% left is pretty damn good imho
Baked Snacks is a great rom ! its no the battery check your TWS

Depends what you are doing, some things (3d games, flash) will drain the battery faster than others.
If you are at 10 hours and 2 hours awake with 35% left, thats not too bad. You should end up around 16-17 hours with 4 hours of awake time.
If you are talking on the phone, that will drain your battery the fastest.
Make sure you completely condition your battery as well (as many posts show)

It will make it through but usually by 5pm its around 30%. I almost have to make an effort to use it sparingly though. I really like the Baked Snack Rom, its very slick probably the best I've had so far. TWS was 3% today.

I haven't even gotten into playing games or watching video on it yet to be honest and my phone calls are usually short.

30% by 5 stop please be happy with that lol

Have you tried SetCPU? I have stock rooted with SetCPU (Perflock Disabler ftw) and without a signal 13-25% of the time (meaning the phone is searching for a signal), I end a 10-12 hour work day with about 45-50% left. Underclocking to 250 while the screen off has helped a lot.

This seems to be a common concern. first please remember to take everything with a grain of salt when it comes to people reporting there battery times. There are just to many factors to say ok if you use this rom and this kernel you will get 20 hours of battery life. Also many of the people reporting battery life exaggerate. sure they may ahve gotten 50 hours between charges on stock battery... but they surely didn't have moderate use ... or any real use during that no matter what they claim.
from another post it seems the majority of people in that post (with everything tweaked calibrated and set up) were getting roughly 13-18 hours of battery life out of there phone with normal use. normal being defined by actually using your phone as a phone as well as using its other capabilities. So my feeling if you are a moderate user you should expect to fall into this area as a goal. Things to help would include setCPU, making sure you turn off data when you shut off screen (or getting a program to do so for you - juicedefender) and making sure you calibrate your battery and battery stats of your phone.
it seems like you are getting close to this range however you are having to watch your use to do so. as others have said the first thing i would do is get setCPU and set up a battery saving profile. read through some of the battery threads if you havent and look for setting changes that wont impact you tremendously but will help save battery (for example if you dont use landscape mode a lot you can turn off autorotation and save some battery). If you are using froyo and are running a task killer uninstall it since it doesnt work any way. While most settings will make a small impact together they should help get you to where you can use your phone moderately through out the day with out worries.

Don't get me wrong here, the thread wasn't about me complaining, more about setting my expectations.
2 Years ago I had the first Touch Pro which would be dead by 3pm regardless of usage. At one point I had 4 batteries. I got the Touch Pro 2 a year later and it could go 2-3 days on single charge with normal usage. It was like night and day.
Granted this is a much more powerful device than either of those, but I feel like I've taken a step backwards with the battery situation.

I tried out SetCPU but the phone was slugglish for me at times and once or twice I had to reboot.
I'm probably just gonna grab an extra battery and a desktop charger so I can charge one battery while the other is in use.

Thanks alot for those tips, I'll give SetCPU another go.
I haven't tried out Juice Defender but I'll look into that as well. Turning off Data when the screen is off might be just the thing I need!

[Q] What's your Battery Life after EB01

I hear constant griping about battery life since EB01. So I was curious what amount of time are people getting on their full charge? I am getting about 13hours. Definitely less than before but tolerable. Have done all the battery wiping techniques. Why is there such a different between users?

I get about 15 hours of good use out of it since updating to EB01. this is with moderate use.

After about 18 hours, I'm generally ~1/3rd the battery left. I'd say a large part of the variance is how we actually use it. I think it'd be good if at the end of the day, you wrote down the unplugged time, the % remaining, the % of the top several items in battery use, as WELL as the actually amount of time for each of them. Right now 'display' has used 41% of my battery, but only been on for 11m45s (the phone has been unplugged for 6h45m, with 72% remaining).
Without the full context, it's extremely hard to actually have any idea what's going on (terms like 'light'/'heavy' use are totally meaningless). One person that regularly gets 2 days (depending on my use I can easily), vs a person that can barely make it through a day... that doesn't mean that the latter person's phone is messed up, they might stream LOTS of music & videos, while the other leaves theirs in airplane mode half the time.
Edit: I'm on SC 2.1, with GPS, all location services, WiFi, and auto rotate off. I leave sync on always, and I'm nearly to 9 hours now... with still 72% remaining... and just dropped to 71%!

Horrible... with vanilla froyo v5 it was amazing, but every other has been almost intolerable. Sc2.4,blackhole,gingerbread... I've tried all of them, for several batt cycles. On second day of miui, ill report in a few days. I've always flashed at full battle, never have GPS or wifi on, turn sync off a lot, and always have my screen turned down. I'm at around 10 ta 13% drain an hour

I know I said I was getting 12-13 hours. Well I did the battery script download and am now at 63% after 12 hours. I would highly recommend giving it a try. It didn't seem to do anything the first day. More the second day couldn't be happier.

SC2.2 nonvoodoo with no power management apps. Overnight off charger for 8 hours battery loss is about 3%. My typical numbers starting from a full charge averaged below.
Screen 3.5 hours.
Calls 45min.
Gmail sync avg. 20 emails.
SMS avg. 30
TWS +/- 4%
BW weather updates hourly.
Those numbers usually get me to about 15-20% battery. So with that usage it can be done in one day or I have also stretched that usage over 2 days.
good day.

Anybody try any of the battery saver apps like super power or juice defender? I have tried juice defender but it wasn't toggling data so now I'm trying superpower & it toggles fine but keeps the phone in partial wake according to spare parts so I wonder if there's any real benefit... I'm now down to 11% after 10 hrs off the charge.

After trying the battery wipe script, and several battery cycles, I'm about 1/3 less battery life than I was on DL09. I'm hoping once we get source, we can get a LV optimized kernel to get it back to where it was.

I used Juice Defender back on DL05, but found that it made my battery run down faster AND it'd cause many of my apps to update inconsistently (using both the default setting, as well as others). Even after disabling, and then uninstalling it, my sync settings were screwed up until I flashed EB01.
I'm not going to trust any of those apps again... thinks work better if you just find apps that aren't power hogs (such as constantly polling the network!).

Back on DL09 SC 0.9, with Adrynalyne's undervolted Voodoo kernel, I could get two days with light usage without trying very hard. Now on EB01 SC 2.4, I struggle to make a full day. Not sure if the drain can be fixed with working kernel source code or not, but I imagine it will help a lot. Until then, I can't bring myself to go back to Eclair again, so for the moment I'm putting up with the poorer battery life and lack of Voodoo sound.

Battery, it's now time to exchange you!

I'm so giddy right now. I've ordered an OEM battery for my Vibrant, and i should be getting it any day now. The reason for me ordering a new battery is limited usage time. Lately when flashing any ROM, I make sure It is at 100% charged. I will normally get about 4.5 or less hours of usage - using a little app named 'Battery Left'.
I don't use a task killer. Ever. I know this has some controversy signed to this, but the Android OS is engineered without issue regarding this.
I Use WiFi whenever I can (uses a fraction of the power 3G radios use). When I CAN'T use WiFi, I make sure it's turned off so it's not wasting power scanning for hotspots.
I make sure GPS is off whenever i'm not using it.
I set display timeout to 30 seconds, set brightness to Auto, or manual and the lowest. Little trick, if Brightness is on manual, you can adjust it on the fly by swiping left or right across the task bar.
I let the battery TOTALLY discharge at least once (twice is better) and then charge to full. This doesn't condition the battery, this just calibrates the battery metering software, so that it knows for sure where zero is, making the metering more accurate.
I try to use a darker colored wallpaper, blacks and reds and deep greens and blues use less power than lighter tones, and white is the worst.
I get a half-day out of my rooted Vibrant on T-Mobile, and I actually use it as a phone (amazing huh?), PDA, game machine, ebook reader, etc, it's not just in my pocket on standby. Battery life has nothing to do with it being unlocked/rooted.
I understand the biggest reason why people think THEIR particular smartphone has some sort of battery problem: They just got it, and are using the hell out of it. We tend to not set it down in the first few days/weeks, we're always fiddling with it, showing it to our friends and co-workers, etc. Once the new and shiny wears off, and we settle into more "normal" usage patterns, we start noticing that we get a lot more battery life out of the device. Some people think that the battery is now "broken in", but the truth is, the USER is broken in.
Some of my POWER hungry apps I use on a daily basis is 'SportsTracker' which I use riding my bicycle to and from work (7.3 miles one way). SportsTrack uses my GPS and tracks my ride in REAL time. It sends a link to Facebook and Twitter, where my friends, and family can watch me go. This app uses about 17% of my battery - one way. So, at the end of the day, just using SportsTracker it uses at least 35% of my battery.
Speaking to the heavy users, how many hours do you normally get using your Vibrant?

With 20-30 calls a day, 20-50 texts, dozen or so emails and listening to music and just geeking on the phone Axura 30 hrs before it is 15% Trigger 24 hrs before 15%, but then, that's how it works for me. Since I got rid of stock roms, I have had ZERO battery problems, I only use Task manager. Deleted all the bloat and I have screen set to 50%. Battery is no longer an issue

With Bionyx 1.3 I let the phone sit idle (exchange email running in the background though) from 8AM and till 4PM it took only 15%
Skype+music+movie for around 1 hours and it's down 15% more (now 70%)
I guess it'll last 1.5 day normal use and 2 days idle use

That's a great battery life. My bionix eats more battery on almost the same usage. I have around 76 user apps installed and some bloater. One thing I have noticed using system panel is when I sleep, my phone sleeps with me and uses an average of 1% battery per hour. Is that good? I still I think im not getting optimal battery life when im actually using the phone.

You guys think that's good battery life? Nah, this is good battery life.

I always got 20-30hours a charge with most of the Bionix roms. However with Bionox 1.3 I struggle to get more than 12 hours with the same usage. I did notice that new app BLN (using your soft keys as notifications) was reported on some other roms as a battery drainer, so I have uninstalled via Titanium. I will report back tomorrow if that is the issue. I still use KA5 modem, so that part has always been a constant

Weird. I'm on 1.3 as well. I'm 15 hours into my charge with normal usage on 3G/WiFi and I've got 25% left.

I'm 15hrs in running Bionix-v 1.2 and i have 42% left. That's with GPS on all day....phone in pocket from unplugging to about 3:30pm. Then only light use.
Days that I use heavily I'll have to plug in around 4pm. I'm not too happy with my battery life. I love my phone...but my old iPhone 3G had top notch battery life! lasting 3 days without charging.
Is it not weird how these times fluctuate so much between users?
Will the new Galaxy S 4G battery fit in our phones? Or will it even be worth it?

Do you have the superpower app? It saves my battery big time when phone is sleeping.

I ordered a batter charger, two spare regular batteries and one spare extended battery last month for my vibrant.
Now I keep a spare charged battery in my pocket and I no longer have to plug my phone in anywhere I go. I just swap batteries and put the dead one on the charger when I get back home.
If I am going to be away from home for more than 24 hours then I put in the extended battery which gives me about 2 days worth of use.
Its a bit of a pain to have to be down for a minute when the battery is dying, but I am more content using the phone this way since I can now keep it with me instead of leaving it upstairs or on my office desk to charge.

My phone is on the stock KA6 kies and from 8-8:30 it is off the charger on 3G. When I get to work it is on WIFI with WIFI Calling(no signal indoors) from 8:30-12:00 and goes back on 3G. then at 12:30 it goes back on WIFI(calling) and sits like that till 5:00. Usage during that time, some email viewing, 10 txt or so, 5 min phone calls and that is it!! from full charge at 8am to 5 pm I'll be at 45-50% battery left and what you read above is all I do with it all day. Battery life is horrible. Not much I can do(unless someone has an idea to fix the issue) as I need WIFI calling otherwise why have a cell phone?

So 16 hours with 3G and WiFi Calling on all the time...on the STOCK Samsung crap? Thats pretty awesome man. WiFi calling is a HUGE drain. Spend the $2 on an app called SystemPanel. It will tell you exactly what is taking up CPU Cycles which, of course, uses battery.
I go 24 hours on a charge with routine use. Granted, everyone's use is different. But I got two days with the KA7 modem on Bionix V. I see no difference with 1.3 (haven't used it enough to tell). Granted, I had WiFi Calling frozen and was on EDGE most of the time and turned on WiFi when I needed it. I've observed WiFi Calling using excessive CPU cycles when it isn't even on. Its pretty poorly coded. I recommend freezing wifi calling when you aren't using it.

[DISCUSS] Battery Life.

Most threads about battery are quite outdated, so I decided to start a new one.
And so recently my battery is starting to get less muscular.. My Xperia Play is 4 and a half months old, and one hour of consistent 3G usage can drop the battery down from 65% to 24%. I'm not very sure whether that is the norm, but if it is, that's bad battery life, in my opinion.
The Android 'Battery Use' page shows that most of my battery is drained from Cell Standby and System Idle (30%).
My wireless and GPS is always off. Am on 2.3.4 rooted.
Also, Gameboid consumes battery like a beast (even more than 3G), but I guess that's due to the high processing power required for emulation..
Is there any way I can improve the battery life?

Personally I found battery life to be terrible on 2.3.4 so I downgraded to R800i_4.0.A.2.368_World. I'm running 122M-1.5Ghz with scary and BFQ, on top of that I undervolted every frequency as much as I could using incredicontrol (Id give you the values but they vary by device). I always leave wifi, bluetooth, gps and data off when not using them, turned off automatic clock updates (there was a battery draining bug with this a while ago) and I run at 10% brightness with autobrightness off. With this set up I lose maybe 3-5% per night, so for around 6-8hrs in standby while I sleep. Ive got similar results on both cyanogen and stock. That being said I don't have a data plan so I do save a lot by not having data on, but a 40% drop in an hour isn't normal - Ive played an N64 emu which runs the processor full speed for that long and only experienced a 15-20% drop.

imho, the best battery life i've experienced is on 2.3.4.. when i'm on 2.3.3 i always lost 30-40% overnight (wifi, bluetooth, 3g, etc are turned off) stock rom, locked BL..

According to some folks, if you're charging your phone and let it stay plugged in for a while after it hits 100% that screws with the battery life.

On 2.3.4 rooted with all the facebook, timescape and other bloat removed my battery is pretty good. Wifi is on 247 and it reverts to hspda when out. Data syncs hourly, and i have contacts, hotmail and gmail syncing.
The other day i was sitting at 57% after 1 day 3 hours, and that included a half hour go on fpse, might have been more.

Battery life seems good to me. I get 1 day usage then charge over night. I do use my phone quite a lot for this (Tapatalk), Phandroid app, Engadget app, Joystiq app and browser. Wifi and GPS is always on.
At a guess I'm using the phone for about 1 hour a time, about 7 times a day... So like 7 hours web use, phone calls and texts, syncing is set to every hour with FiX on.
When I was on 2.3.3 I'd be lucky to get 10 hours out of the battery but 2.3.4 is awesome.
Edit. Obviously I play games too. Forgot to mention that.

Actually I get similar idle battery drain rates as you, but personally I'm not very concerned with battery drain as long as it's not so much. I'm more troubled with battery life on consistent usage, which I feel the Xperia Play (or at least mine) sucks at.
When I play Gameboid, I get the same fast battery drop too - 40-50% in one hour.

Yep, I read that from a lot of places too. I admit I used to do that (and have since stopped doing that), but sometimes I can't help it if I forgot to charge at night before I sleep (and have to charge overnight to ensure I have battery the next day).

I envy your battery life One thing, if you remove Facebook, will your Facebook contacts picture sync go away too?
And did you remove the bloat stuff by deleting them from /system/app?

Sigh, I could never get such good battery life..

All the more reason to undervolt, in standby undervolting doesn't have much of an effect on the phone since the processor is either in deep sleep or running at its lowest speed. Also using a governer like scary or smartass helps keep your device running at a lower frequency when possible. Like I said 2.3.4 was terrible for me, 10% drain overnight or more, but apparently YMMV with this. That being said 40-50% drain in an hour is crazy no matter what you're doing on the phone, like I said running N64oid for an hour drops me 15-20% keeping in mind this is at 1.5GHz with sound and the backlight constantly on. If all else fails you can always wipe everything and start fresh, carrying over the same settings while jumping around firmware can lead to some undesirable results. Anyway good luck and keep us posted

The facebook sync option doesn't appear on my anymore, although it used to. To clean it up all i did was :
Purchase Titanium Bakup
Freeze the things I wanted to remove and test rebooting, only freezing a few more each time
Backed up every app
Slowly uninstalled each one with a reboot every couple of apps
Enjoyed my faster phone with better battery life
I use the gmail sync and life.contacts for contact pics

I get amazing battery life on 2.3.4.
In stand-by I lose 1% every 3'rd hours. It's very good in use too. Yesterday I had my day with heaviest use so far and texted like crazy the whole day and a lot of phone calls. Some surfing, gaming and updating of apps between that. Basically the phone was frequently used the whole day with short periods of stand-by in between. At night when I went to bed the battery was at 40%.
Earlier this week I used it minimally for 2 days. The battery dropped 10% for each of those days. But that was very minimal use.
So in short. I have not experiences better battery life on any other Android phone. What takes the most power is emulating. It can suck up like 20% in an hour depending on which emulator I use.

I got my Play at the beginning of the week and with quite intensive use, without WiFi or 3g, I scraped an 8am to 6pmish day on the battery. Admittedly with a fair bit of gaming.
However, that was only waiting for my 2600mAh battery to arrive and now I'm using it, I would recommend it for the bulk. You don't notice it after half an hour or so and I have no issues with gaming on the go whereas I always thought it may die on the stock.

mine drops 4 - 5% /hour..... much faster than b4.... dn no w is goin on w/ ma PLAY.....

I found that since updating to 2.3.4 my battery drains quicker. Usually charge overnight and battery would be around 15% bedtime. (7am - 11pm approximately)
Now I'm finding that by 6pm I'm having to charge it and that's without gaming

Three times in my first week and a half of ownership I awoke to find it completely dead despite fully charging it or nearly fully charging it before bed. I usually sleep with my phone next to my head so that I can ensure that the alarm will wake me up. That and the lack of a timer function really irk me about this phone. I really hate having to create and save an alarm when I know I only have 45 minutes or 2 hours to sleep (I work a grave shift and have inconsistent sleep schedules during the day). It adds insult to injury when something changes that lets me get another 5, 10, 20 minutes or so and I can't easily add it. On top of that, I have to go back and delete all the alarms I made throughout the day!

According to some folks, if you're charging your phone and let it stay plugged in for a while after it hits 100% that screws with the battery life.

Thats crap. Infact you should leave your phone plugged in a good 30/45 mins after it says fully charged if you want a full charge

Isn't it also beneficial to Li-ion's health to keep them at max charge whenever possible?...

Not at true max but at what the battery controller considers max. True maximum will drastically decrease the total cycles just like true minimum only to gain longer cycles in the short-term. When you store a battery it's best to stop at 75-80% because it will lose stored energy slower and not spend nearly as much time near 100%, which is still a trade-off between long cycles and more cycles.

What do you guys think to this?

Its the same size as the standard stock battery so there's no extra bulk... But gives an extra 930mah?
To be honest, I am somewhat tempted... However the question is, will it explode in my pocket and result in me losing half my leg? It's quite a big risk to take! There also might be a voltage difference, however I cannot see anything on that.
Im currently on 1.6Ghz, undervolted. And I just played Order and Chaos for 35 minutes and went from 86% to 63% - I've had bad luck in the past regarding phone batteries, I remember replacing my G1 battery around 7 times, but at these rates my Play would be dead after around 3 hours or less of gaming.

how do you update to 2.3.4 it wont show me =[ please someone answer me :/

You have to expect that with any phone playing an online game. Wifi/screen/GPU/CPU are going at full wack at the same time. What dya expect?
