My - Battery Sucks -

I have to charge it twice a day, and my use is for only couple of hours talking and few browsing.
I tried that with stock as well as
[ROM] cwm-Phantom-X-
is anyone else also experiencing the same?

a few hours being like 10 hours straight talking?

You're crazy. This battery is the best I've seen in a long time.

im getting 12 hours with normal use and 8-9hours with very very heavy use(basically on my phone all day non stop)

I can drain a battery in 6 hours or less. I can't make it through a 8 hour work day without charging it. I guess you guys that go 12+ hours on a charge aren't power users. I tried every rom and kernel and my results are exactly the same.

Maybe the people who are complaining about battery life came from a flip phone or a blackberry. As far as smartphones go, this is the best you'll find for the features and enormous screen we have. Don't believe me then get an Amaze, Sensation, myTouch 4g Slide or G2x.

this is exactly what I am talking about.
Before I had HTC G2 and same amount of use it last for whole day (around 12+ hours) but this one hardly goes upto 7-8 hours with one charge...
I did the battery wipe with full charge, if that makes any difference.

I dont know bout anyone else... but the only battery problems ive experienced is the fact that ive become so damn lazy on keeping the phone charged.
The battery lasts so long that i forget to charge it, and then i run out of battery

I'm a heavy user literally all I do is watch 1080p movies and plays games on my phone. I get twelve to fourteen hours every day. I also get at least a text every fifteen minutes if not more. Maybe the developers didn't remove career ciq which bogs down performance and drain the battery. You can also try a different kernel.

don't forget that in areas where you have crappy signal, you phone pumps up the power to try and compensate. you may notice your phone heating up in your pocket too. If you have no signal at all, i weep for your battery life.
go into airplane mode to save juice.

I too get 24 hours or more from light to moderate use with juggernaut.
Heavy use still nets me at least 10 hours. Although I toggle things off if I remember and don't need them. Like wifi, data, auto bright, sync, etc. although WAY lead important with this phone than it was with vibrant running cm7.

I had some weird battery drain with the stock rom. I couldnt get more than 5 hrs with light usage or heavy usage. I flashed streamlined (a mostly stock rom) from teshxx and im back to having 9-10hrs of battery life with moderate to heavy usage (3hrs of on screen time)

I have a 12-14 hour work day and I have 25-35% battery life left when I get home, heavy usage. Best stock battery for Android I've ever had. This is my 8th Android phone.

Why don't you try adding another core to your G2 and see if you can even get 6+ hours!!!
Cmon man, this is a dual core phone...it's just common sense that it will use twice as much battery power to get it to run smoothly.
But honestly, I was able to get 21hrs out of a full charge. With heavy use but i had it UC'd @ 1.2max and 192min. Still ran pretty smooth tho.

I get about 18 to 20 hours from a full charge. Stock. Non-rooted, and no modifications of any kind. I have all my apps auto-sync every 4 hours, and my usual display "on time" is around 4 to 5 hours. Here are some screen shots. This is the best battery life I ever had.

Just to add. My brightness is at 40%

is it better to use autobrightness on our device or a set brightness setting to save battery?

I'd say set it to certain level. Having the phone constantly adjust I would think would use more battery.

Ughh battery drain definitely too fast.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.

Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?

Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.

Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

Wow, really? At first glance in all sub-forums I saw about two, if that. I have a legitimate concern, especially when my friend is getting about 4 times better life. Thanks for your help though in the device forum where this 'doesn't belong'.
..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.

I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel

From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.

Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise

Do I have a bad battery or phone?

I get 3-4 hours battery life at best I see people saying they get 10 hours I don't see how that is possible? Is my phone a dud or what this is very frustrating. It does the samething On the extended 2100mah battery. I'm running aopk milestone 4 and glados kernel
Sent from my Galaxy Nexus using xda premium

It looks like you were had screen on for close to 2 hours and made a phone call, albeit short. This is normal battery life for as much as you use the device.

You should try manually sync or set the syncing interval as high as possible.
Wifi always ON doesn't affect the battery life unless your wireless connection is weak/unstable.
Lower your screen's brightness or use Auto Brightness.
Fully charge your phone and let it alone for 2, 3 hours and check how much battery drains. If it drains 3-4% in idle mode, it's normal. Check also if your phone wakes up a lot, maybe some apps are running in the background and they wake your phone up frequently.
Hope it helps.

I used to have really poor battery life and like you wondered how people managed to get the stats I was seeing here.
I recently decided to do a factory reset for a different reason and to my surprise my battery life has improved incredibly. Yesterday I got over 18 hours in total with over 4 hours on screen time. This was with the stock gsm battery. Granted I was using wifi throughout but I was lucky to get 8 hours before the reset, even with wifi. With 3g I'm now getting 14 hours easily with over 3 hours screen time.
My point is if you've never done a factory reset, you may want to give it a go.

It's a bit hard to diagnose the problem based on only a screenshot of your battery stats.
Since your screen is using over 50% of your battery life, my guess is that you just had your screen on for about two hours of the total two hours and forty-five minutes. It's normal to not get more than about two hours of screen time. (Tap on the Screen part of battery stats to get more info on how long the screen was on for.)
In my experience with three Android phones (MyTouch 3G, MyTouch 4G, Galaxy Nexus), all the usual tips to conserve battery life pretty much do nothing to improve battery life: turning off syncing and background data, turning off wireless, don't use widgets, turn off GPS, etc.
Pretty much there are two big battery suckers on Android phones and particularly the Galaxy Nexus--the screen being on and LTE being on. If you dim the screen or just keep it off, you will seriously prolong the battery life. And if you use CDMA only, you will also seriously prolong your phone's battery life.
That said, it's also possible something is wrong with your phone... or your battery. We can't know just from the screenshot you posted.

This looks normal. How much screen on time do you have?

My screen on time is about 1h 30 minutes with WiFi ON.. 3g/sync/gps off auto brightness

[Q] Battery Life after Blu Kuban

Hey all,
I recently put Blu Kuban on my phone and I'm loving the look and feel, but I'm having REALLY bad battery life. I couldn't get through the day with only a little use. I download the battery calibration app and tried that. Its also been about 4 days since I flashed the new ROM. Anymore suggestions? I bought an extended battery at 3800 mAh and I'm getting less than a day with the new ROM. Before the update I was getting at least a day and a half with MUCH more usage.
So long story short, BAD battery life. Any suggestions? If I cant get this figured out, I'm going to have to go back to stock.
Thanks in advance.

Hi. I've noticed you posted two separate threads relating to RUJELUS' Blu Kuban ROM. I would suggest you ask in his thread if you haven't already due to the fact that he may offer more assistance.
However, there are many different battery solutions. The problem is, if you were previously running Stock Gingerbread, you must get used to the fact that until Kernel source drops, battery life will not be as good on ICS as it is on GB.
To address your ICS battery problems, I suggest you turn here:
http://forum.xda-developers.com/showthread.php?t=1668853
Also, if possible, it would be nice to see your battery stats. Take screenshots and post them up here.

I would definitely post in the thread if xda would let me. I tried because I had that thought originally and because I don't have 10 posts yet it wouldn't let me post in the thread. I will post battery pictures tomorrow but its pretty much saying like 36% android OS, 20% display at one hour of use.
Thanks for the help so far guys. I checked out the first link and changed a few things. Hopefully it helps.

Still rocking Gingerbread ;p

How old is your battery?
How old is your phone?
How much do you have running in the background?
Do you keep WiFi on at all times (so that it might be searching for signals constantly)?
Use the apps listed above to try and get an idea of what could be causing the drain.
Hopefully it will improve so you can fully enjoy the ROM.

My phone was purchased in October. My battery is about 2 weeks old. I don't believe i have anything but gmail sync in the background. However, I'm not used to all apps I used staying open after I use them so I've been kinda bad about closing them. Is there something I can change so this goes back to closing most things after I press the back button. I do not keep WiFi on.
My extended battery got about 18 hours and was at 15%. I slept for 11 hours last night with nothing on. I used facebook for 15 minutes, just responding to a post and scrolling through messages and battery dropped at least 10% if not more. Granted, I was trying to download the update but doing that for 10 minutes dropped my battery over 20%. I'm very concerned.

I essentially didn't use my phone for half the day. I can't expect with a battery double the size to get 12 hours of light use?

are you on the latest build? Im on 1.0.4.1 and my battery is pretty solid, Id say give it a few days. are trying different modems?

I experienced the exact same thing on that rom. It is definitely one of my favorite roms but I would get half the life that I would on the others I tried.
Were you having issues with battery at all before you flashed the Blu Kuban?
I'm running Blazer ICS now and getting almost as good of battery life as I had on Gingerbread.

So here is my screenshot. In next post ill type how long each process was running.

Cell Standby: Time without signal 4%
I figure thats enough but if not let me know. I just updated to the new version so I guess I'll have to give it another few days, however this was typical of the last version. Please help, I really like Blu Kuban.

1. You're addicted to Facebook lol
2. Your signal seems very low...could be your phone is running up its battery trying to get signal
3. What are your wifi settings? Use one band only and leave sleep mode "always"
4. What is the brightness on your screen? Set it lower and unselect auto adjust
5. Sync can kill your battery, either remove some things from sync (like Facebook) or remove them all and only sync manually

Wow, that is incredible!
You slept 11 hours? I have not gotten that much sleep in years!
In all seriousness, I have recently gone back to Blu Kuban and the battery life will get better after at least two full charge cycles. I am currently at 9 hours and 75% remaining. I am in a low signal area and keep data off and use wifif when available. I do use Juice Defender to automatically turn wifi off when the screen is off, so when I am not using my phone, I can still receive calls and SMS.

My battery life on Blu Kuban is really good... been getting like 25-30 hours for the past couple of days. One thing that you can do to maximize battery life is turn off haptic feedback and also turn off pulse notifications. Pulse keeps your phone from entering Deep Sleep and haptic feedback also uses a lot of unnecessary battery.

I found out what my problem was. My extended battery has gone to ****. I took my extended battery out yesterday and put in my standard battery and it is running better than the extended battery. What is crazy is that I replaced my stock battery because it was running poorly and not getting good life. Therefore my 3600mAh battery is running worse than a BAD 1800mAh battery.
Tips though to improve battery life that I found:
Download CPU Spy
Download GSam Battery Monitor (Previously known as Badass Battery Monitor)
- Use this to see what is using your battery up.
Turn off any data syncing you don't need
Turn down screen brightness to an acceptable level
Make sure you close the facebook app because its a crazy battery drain
Give your battery a few days on a new rom to even out
This is what I can think of right now.
Good Luck all!

Hyperion battery under-performing?

Got the Hyperion last week from Amazon and overall I was impressed with its initial performance. It was a huge boost from the oem battery as I didn't have to recharge my phone at all during the day.
My only concern is that I've noticed I haven't been seeing similar numbers as others have mentioned with their Hyperion. I mean, I'm not getting 24+ hrs of use with 8 hrs of on screen time. I'll take a photo next time when its at its lowest charge but I am averaging about 5-6 hrs of on screen time, and thats with basic use, surfing the web, texting, couple phone calls, no games or movies, wifi/gps/sync on, and 30% brightness, non rooted as well.
Does anyone else feel their Hyperion isn't performing as others have claimed?

24+ hours with 8+ hours screen is is down right impossible. The reason people get extended batteries is because they want more than the stocks screen time for 4-5 hours without worrying about their phone dying.

Not really... With the correct kernel and ROM I can push that if not surpass it. Paranoid 2.51 leankernel 1.6 been home all day from the storm... That's 3 hours 12 mins screen on time @ 67% juice left.

For me, not so much. Today for an example, I got a little over 12 hrs until I hit the 5% mark with almost 6 hours of screen on time. Home all day too with wifi on and screen brightness at 30%.
One thing I did notice though is that the "sdcard" used 1 hr and 17 mins of the battery. I've never even seen the sdcard on the activity list before, this is the 2nd time I've seen it since installing the Hyperion battery. Hmm what could it be?

I almost made it.. I'm running Aokp build 4. Not sure what the kernel is.
Plus the batteries have to go through a charging period... I noticed the first day it lasted a long time almost 2 days. (1day22hrs)I forget what the screen on time.

Have you looked at any wakelocks your getting with better battery stats? That is pretty bad for the 4200 batt. Did you do the charging cycles that were detailed in the user manual?

Hey I was just passing by and reading threads, although I don't have this battery, a very possible reason that your battery life might not be as good is that you're still on stock. Notice everyone else who posted is on a custom rom + kernel. The GS3 stock roms are nice but come very bloated with apps. I read somewhere that on stock when you start up your phone, by default it starts a very impressively high number of processes ~50ish. I could be wrong on that but yeah a bloated stock rom MIGHT be the problem. Just my thought.

Have you looked at any wakelocks your getting with better battery stats? That is pretty bad for the 4200 batt. Did you do the charging cycles that were detailed in the user manual?

No I have not tried that app yet.
And yes I did follow the initial charging instructions as well.
It has to be something with the phone because even with the stock battery I had terrible performance, it'd last me only 3 hrs of on screen time where I've heard most users receive around 5.
He is my cpu time, it seems normal since the phone is spent most of its time in deep sleep.

Good at first/No so good after a couple months?
I havce the Hyperion, and have experienced close to 48 hours of life, albeit with very little use. With moderate use, I've experienced 30 hours. My screen time never surpasses 3 hours per day.
A few weeks ago I installed the Serenity 1.1 ROM. I have not been able to get more than 15 hours with that ROM.
This morning, I put in my stock battery, and it has been in for 9 hours so far, and is currently at 83%. I did a reboot about 4 hours ago, so don't have accurate screen-on stats. But I'm never at 83% this time of day with the Hyperion.
ANyone else experience good, then later, poor performance from this battery?

In the beginning I head awesome battery power. Now the battery is horrible I only get 2 hours screen time at 65 percent. Any ideas? Also undervolted and running 1.8mhz but battery still runs hot.
