why is my battery life so bad

I am running liquid smooth 1.25 right now. That included lean kernal. But my battery life is horrible.
I lose 1-2% a MINUTE running gps navigation. I was on vacation with a friend and we used his razr to navigate around san francisco literally all day and when we got back to the hotel he had over half battery. He is running stock though, should i switch back to stock?
I played gameboid for an hour and lost about 40% battery power.
I have tried hotplugx and interactivex, no help.
Is the battery life for this phone really that bad?

Take note of your screen on time. And have a look at the other 17 threads about battery life. But to answer your question: yes, it is that bad.

I recommend buy the extended battery also running foxhound rom 4.0.3 seems better than liquidsmooth 1.25 also be weary liquidsmooth1.35 my google play wouldnt show all apps available foxhound does not have this flaw mod options clean quick great battery

It's the price you pay for AMOLED screens. Trade it in for a TFT or IPS phone if you want better battery life.

are you running anything else?
are you running anything else in the background? Do you have wifi on? Do you have anything set up for auto updating? Also, were you going in and out of service a lot? I've read many posted about these issues running battery life down. Try checking if your baseband is up to date. I don't know if any of this will help.

Truth. AMOLED screens consume a lot of power.

battery isue with JB

strange thing is going on. my battery dropped form 50 to 17 %, than from 30 to 9% ect. before that i took out battery because i wanted to see something.
after that. battery life is getting worse. usually i could get about 4-4.5 hours of screen time. but now only 2-3 hours.
what is going on with my battery

Check your apps and install BetterBatterStats. It could be rogue apps not letting the phone go to sleep or making it work more than it should.

I am having similar issues (Jellybean Vicious Jellybean4.1.1 AOSP, faux kernal). I can literally see the battery percentage go down a percent every 30 seconds or so when i am using my phone / surfing web / streaming music.
Cant post in the main forum now - any suggestions would be appreciated.

It is often the kernal with the new JB roms. In an older build of Franco's kernal if you opened the camera when you first started the phone it would fix battery drain. I suggest a new kernal! (Franco's runs great on mine! ). If this doesn't work you might want to recalibrate your battery. This app works great, search "batterycalibration" on the play store. It will delete your battery data so your phone will charge to an actual 100%. Hope this helps!

There is so much wrong about this post its not even funny.
All kernels are pretty much equal. It all depends on how you tune it. You cannot calibrate your battery... all that does is delete battery stats. Which again DOES NOTHING.

My N7 running JB gets great battery life, but the GNex on JB is crap when it comes to battery. I'm often out of battery by 3-4pm in the afternoon.

The GNex has a 1850 mAh battery while the N7 has a 4326 giant mAh battery. That's more than twice the juice. What did you expect?

I've experienced crap battery since moving moving to JB as well. Same kernel and I can only manage 3.5 hours of display over like 8 hours. On Wi-Fi. Whereas on ICS same kernel as JB I was getting 5 hours. Its not just this guy.

I picked up a spare battery over the weekend (identical 1750mAh Samsung batteries), and today I ran the first one from 100% down to below 30%, and swapped. When I arrived home, I popped in the first one to charge it, only to find it is at 58%. I guess the principle is to not pay too much attention to the exact number, and to keep all my batteries as highly charged as possible...
I don't seem to have any rogue apps. The phone appears to sleep very well when I'm not actively using it.

If your battery randomly drops when you reboot your phone do this :
Let it die completely until it turns off, keep it turned off and then charge it completely (usually overnight ) and then turn it back on and it'll show you a very accurate battery percentage

Verizon Galaxy Nexus 3g browsing battery life

My web browsing battery life is horrible. I turned off 4g and I still see my battery drop roughly 1% every minute. That means I don't even get 2 hours of screen on time. The battery drain also seems similar when on 4g so there really isn't a difference. My wifi battery life is a little better. I can maybe get 2.5- 3 hours screen on time. I switched my battery for a qcell 3800mah battery, yet the internet browsing battery life still seems to be the same. Roughly 1% drain every minute. With wifi and the new battery I get roughly 3.5-4 hours screen on time. I have used a number roms from CM10 to Aokp to Jelly Belly, and am currently using codename android and recently switched the kernel to air kernel. My screen brightness is usually 60% and everything like gps, nfc, and auto sync are normally turned off. Is there anything I can do the get better battery life such as using a different radio or is anyone having similar battery issues? Thank You

It is hard to get awesome battery life on the VZW version. I have been dealing with the same. I honestly think my issue is the newness of 4g. I cane from iPhone and inc2 which in my opinion had the best battery life of current phones.

There's nothing wrong with that battery life/screen on time. There is no other Android phone that's going to perform a great deal better than that on 3G/4G with heavy web browsing. You're expecting more than what exists in the public technology and hardware at this point in time.
Sent from my Stock AOSP Android 4.1.1 Galaxy Nexus

I appreciate the replies and feel a little better that I'm not the only one having problems with browsing over 3g. The weird thing is though, that I'm still getting less than two hours of screen on time of straight browsing with the extended 3800mah battery. Wouldn't the battery be at least at 3-4 hours cause its double the capacity. Also what are the temperatures of your phone after heavy use, because the top screen area of my phone gets extremely hot and the temperature can get to 120 degrees.

Try out SetCPU and if you like it, support it by buying it in Google Play.
I use Franco's nightly 241 with the GPU OC'd at 384 and the CPU underclocked at 1GHz. If I start seeing the phone get jittery, I bump it up as needed and the kernel supports up to 1.8 GHz. If I walk around with it at 1.0 GHz, I can get moderate to heavy use out of it from 7:30 to about 6:00 on the stock battery.
The versions of SetCPU that are up on that post are over a year old. If they don't work (which I haven't tried them on the gnex), just test one of the free ones on the market.

[Q] [q] Is this what a dying battery looks like?

I noticed when I was looking at battery stats (trying to figure out what's eating the battery; very little in the way of apps installed)
I bought the phone last week, but I bought it used on eBay. It came with the original box and the manufacture date is 6/30/12, so I figure this was someone's everyday device for 10 months.
The reason I ask is that sudden dip from 20 to 30%. And the other reason I ask is that I only get about 10 hours with 3 hours of screen-on time on a full charge. If the battery is just losing capacity, that's fine - I'll get a ZeroLemon 2300maH battery and I should get much better life. If the battery still has close to full capacity, then I'll get an extended-capacity battery. I just need some guidance as to whether or not it's crapping out so I have a better idea of what to buy.
Thanks!

Jump is weird. Could be the battery is flaky. But I would make effort to reseat it. I want to see what BetterBatteryStats says about that terrible wakelocking, though.
You can delete batterystats.bin from /data/system. Everyone says it does nothing. But I do it anyway. Because I can.

My stock battery usually gives me 7-8hrs of standby and 3hrs of screen time.
Zerolemon 2300mah gives me 20hrs of standby and usually 5hrs of screen time.
You can check in the accessories section in the zerolemon 2300mah that I've posted some of my results via screenshots.
About the dip, I'm not sure I've never noticed that on any of my batteries.

Jump has been there consistently. Had the phone 4 days, and every day when it hits 30% it drops to 20%.
Installed Betterbatterystats and I'll see what's keeping it awake. It does seem to be awake an awful lot compared to my old Atrix (switched to T-Mobile a month or so ago, and just got the phone after I was switched for a bit), which got way better battery life.

10 hours with 3 hours of on screen time is just about average for the stock battery.
I would recommended getting the zero lemon 2300 mAh slim batteries if you're lucky enough to place an order for them. They only restock in small amounts and they disappear quick.

Well that's good to know. They're in stock right now on Amazon so I'll pick up the 2-pack with the charger.

OK so far the phone has spent half its time unplugged staying awake, and about half of that is being caused by DeskSMS. I got a trial a long time back and decided not to bother because I didn't use it, and when my google account restored to the phone, it apparently got installed and I didn't notice. I've uninstalled that and we'll see what else happens. Very thankful for the BetterBatteryStats suggestion; I'd never heard of it.

Well the battery is lithium ion. With repeated charging the battery loses capacity. If the battery is the one that came with the phone, buy a new stock one for cheap off Amazon. That is if you use NFC and have a certain fitted case. If not, go for an extended battery by reviews on Amazon and XDA. My battery is from December and I haven't noticed any decrease yet. The temperature of which your phone runs and the temperature of the environment also effect battery life.

Great news, everyone. Desk Sms was the culprit all along. This is 3 hours of Netflix and then sleep over night. Just a couple wake locks that I can attribute to emails received overnight.
So out turns out the battery other than the weird drop, at least with the power saver on.
Thanks in particular for the Better Battery Stats suggestion. Without it I would have been majorly confused.

Glad you were able to get it all figured out. Wakelocks are VERY annoying. Search for kms.apk if Mediaserver is ever draining your battery in the future, it is a common battery draining problem as well.
If you're on TouchWiz using Power Saver, I'd recommend disabling it. It throttles your CPU in half. This may cause instability, or overheating problems or sometimes even battery drain ironically. I do however recommend, KT747 kernel with changing govs, and I/O scheduler and using Team Kernelizer tweaks. Try Eugene's CPUSleeper and it may help put DeskSMS to sleep for good. And how could I forget? Definitely try Greenify. It makes apps behave akin to iOS devices. Best of luck.

The problem with Greenify, in this case, is you can't hibernate apps that send notifications, or you will never get them.

The power saver doesn't bother me. Being in the notification area makes it easy to toggle and performance has been fine. Better Battery Stats says it gets up to 1 GHz Mac and that is plenty on the web or Facebook or Netflix.
I had assumed the media server popping up was due to Netflix streaming. It hasn't been back today since recharging. If it comes back I'll look more at disabling. Today battery life has been great. 12 hours with 2 hours of on time and at 45 percent. I definitely over reacted to the drop and it must have been Desk SMS which never should have been installed.

If anyone has any issue with their battery sprint corp stores have a tester takes about ten min. They won't have a problem doing it if you're nice, sprint or not. It will either end up excellent marginal or poor... they don't charge for the test.

This is it !!

I am extremely frustrated. My phone has always been bad with battery life. Its been over a year or so that I have not seen my phone last longer than 5-6 hours. I am constantly looking for any chance I get to charge my phone. My life revolves around checking battery %age and plugs to charge. Smart phones were suppose to be helping us, but its like they are using me to feed the juice every chance they get.
My T989 is a "SMART" phone with
- lowest on screen brightness (and a screen dimmer overlay)
- no NFC
- no haptic feedback or keytone sounds
- No animations or graphic heavy launchers
- dont play games any more
- turn off 4G/data anytime I get a chance
- No GPS
- Manual Sync emails, facebook and whatsapp
HELL, I want to go back to the age of Nokia's where the batteries would last you through weekend and still some juice left even after it goes through laundry.
But that is not what I am here to complaint about.
I would like to know what ROM+Kernel you have and how much battery life you get ? (w/ screen time)
Who else is going through these ?
Note: Currently on JB stock and a new OEM replacement battery

How often are you using your phone? It uses a lot more battery when the screen is on. You can get over 24 hours of battery life by not touching your phone at all/no apps running.
I think most people average around 3 hours of display time without charging. Check in settings/battery/display.
I'm running AOKP and depending on how often I use my phone it can really deplete my battery.

I've been running CM 10 for awhile, and I've been getting great battery life. Recently It's been sliding, and it's due to my battery just being old. I've got a new one I'll be putting in tonight. Get Gsam Battery monitor and check out what's using the battery.

easiest way i have found to extend my battery during the day is to toggle my data..if i am not using it for a bit, just toggle it off, takes 2 sec to toggle it on, and can easily double my battery life..

I use Jedi mind trick with Tiberius kernel. It fly's and I get around 12-14hrs with 1hr and 30mins or so with Facebook 1hour and half of music and texting. So get it!

Do this stuff and read it carefully. And yes 3 to 4 hours is about average screen time. Makes no difference discussing total battery time. You can kill it 3 hours from a full charge with continuous use...or it can last 24 hours....all depends how often your using it and what you are doing with it.
If you go thru this other thread and follow all of the advice ....you should be fine.

These are my results, after buying the LAZA 3800mAh battery. I just had it for one day and it is light years ahead of the stock battery. I don't use NFC, and my brightness is all the way down. (Still I don't believe the brightness is low enough, seems too bright). I am a student so when I'm in class I can't obviously use my phone, so that is why the screen time is below what you guys expect. Still this battery is legit! I got it for $23 shipped (Amazon Prime). On the stock battery I had to revert back to ICS, but with this Laza battery I have no gripes on leaving it on the latest CM10.2 (4.3.1) and letting it go on Dual Carriage (DC, HSPA+42) mode. As long as I leave school with more than 70 percent battery like on my HTC Sensation, I am fine.

I do have GSAM battery monitor installed. I had it installed since it was called "bad ass battery monitor". It always is consistent and shows that screen uses most battery (abt 35% of overall usage), even at lowest setting. I also have a screen Filter app https://play.google.com/store/apps/details?id=com.haxor That overlays on the screen that dims it even further and is believed to save some more battery.
The other major user is the apps which is
- Android &
- Kernel

Dude.....less than an hour screen time tells something is very wrong.
First...I would bet the screen dimmer app Burns more battery than it saves.....that'd be my guess.
Second....flash a fresh rom, or stock. Run it at least a few days as is. With only gsam and cpuspy installed. Nothing else. I know you may really miss some apps....but its the only way to see if its an app, or rom, or hardware.
Then off gps after your install. Its on by default and is a huge battery sucker.
I'll bet things will be greatly improved. Then install apps.....monitor closely for changes in gsam or cpuspy.
Your screen battery usage should be more like 60 percent or higher....even as dim as it goes. That's normal. Apps, maybe 30 percent and then the other stuff. A 35 percent battery drain from the screen says you have problems.
After all your apps are installed.....try everything in that link I posted. Everything. And things should stay good.
Keep us posted.
