Thats a drastic drop! Id say about normal as well. Did you have a lot of apps that were re downloading from the time you first activated it. After a few days to a week when your done looking at your phone every 5 secs you'll start to see battery improvement haha.
Tonight will be my 3rd time charging it. WIll it get a lot better tomorrow?
ProTip: Put the phone down every once in a while and enjoy life.
That's normal if ur 4g on

It can take 4-5 charge cycles for the battery to really get worked in.
Also, check out the juice defender plus app. Doubled my battery life.

Lithium Ion cells do not get better in any way after a few charges.
In fact the capacity goes down a wee tiny little bit with each and every charge, so your first charge was the "best" one.
Stop playing around with the thing for 5 hours non stop and you will get decent runtime.
Best thing to do with a new device is to charge it up fully as soon as you can. Then run it down until you get the low battery warning. Then charge it back up.
Battery life will likely be pretty poor for the first week or so, then it will normalize.
Deep discharging (to 0%) is about the worst thing you can do to a LiIon battery, because it "hurts" it much more than several shallow discharges.
Also, like I said before, battery capacity won't in any way rise or "normalize" over the first week.
Battery life is poor the first days because you use your shiny new device all the time (i.e. more than later). It's like that for all of us.
My battery life sucked the first few days, It got better though. It really only seems to suck it down if it is hunting for a signal constantly.

If you are using your phone a laptop replacement and are surfing the web constantly, expect it to die like a laptop.

You also need to try this manual battery calibration:
http://myhtcdesire.com/tutorials/how-to-improve-your-battery-life-calibration-tutorial
After I did this, saw the battery reading 99% and 98% more often rather than straight to 96% after charged.
Originally, it was suggested by HTC tech support. I did that once every six months or so ... And my battery level is now improved. Screenshots will follow in the next post.
Not bad?
Sync is off btw. And this includes using Maps 2%.
At least with my usage pattern, I am more or less satisfied.
I wish Google fixes the high Android OS Keep awake time!

You need to remember the only thing relating to battery life is not just the battery, it's software as well, hence calibration. After about a week or so your phone gets a "feel" for your battery and gets more battery stats, so it's more accurate with it's readings. That is a proven fact, you need to think about all things.

It is quite easy to gauge a Lithium Ion battery. 4.20 V = full. 3.60 V = empty. Your phone can read the battery precise to 0.001 V. The curve isn't linear, but it's well known what voltage relates to the exact capacity left in the battery.
There's really no room to "feel" anything there, just simple math.

I consistently get 15-18 hours of use out of mine with the extended battery.
But to the OP, if your screen is taking up 60% of your battery, it's always on, your battery is gonna die, it happens. Your battery doesn't get "better" with time. It seems that way because you aren't glued to the device 24/7.
Mine was god awful when I first got it but after a week or so it got much, much better.
I have the GSM version though.
60% screen time gawt damn! Did you talk to anyone that day?

Google need to run classes on how to read the battery consumption pages. 61% screen means that the screen used 61% of the total battery used, not that the screen was on 61% of the time.

By about the 3rd day it seemed better. But it's also difficult to gauge because the first few days you're bound to toy with it constantly.
Until there is an empirical way to gauge usage, like an amp meter attached to the phone - it's all perception imo.

Do yourself a favor and try aokp milestone 1 from rootzwiki , and also download lean kernel 1.1.1 on xda. Use interactiveX governor for kernel. This is the exact setup I am using now, and have been for a few days and have been getting insane battery life. Hope everything works for you.

You really have no idea what you're talking about. First of all, it will get better, I won't bother explaining the science behind it considering you can do your own research, but it will, also, it can't be "fixed." Just like they can't make it an 8 mega pixel camera in an OTA. You can get it much better by doing custom roms and thigns of that nature.

It got better when I turned off vzw backup and google +.
Best I got is 16 hours bone stock just an extended battery. Worst I got was 4 hours(screen was on the whole time) watched 2 movies before I plugged in. I average around 12 hours from 100% to 20%.

First off, it's hard to tell by your screenshot how good or bad your battery life is. You're burning approximately 10%/hr, but maybe you had your screen on or were surfing the internet for a portion of that time. Anything that involves data transfer will kill your battery faster.
I got my Galaxy Nexus on Wednesday, and I've had great battery from the start. I calibrated it by letting the phone's initial charge die down to zero, and then charged it all the way up to 100%, and then used the Battery Calibration tool. I drain between 2-3% hour with light use, but can obviously drain much more depending on what I'm using the phone for.
That being said, for those on this board who think an OS upgrade is going to fix the problem, I highly doubt it. I have a reasonably poor cell signal (averages around -95 dbm), but still get solid battery life. Given that we were all issued phones with the same software, if you're experiencing incredibly bad battery life, I'm going to point my finger at the hardware. It just doesn't make sense that some of us with 4.0.2 get great battery life, and others do not. You probably have either a bad battery or a bad phone. Now, I'll probably get called out for saying this, but watch all the posts that follow when the update releases, when people still have poor battery life.
This is my 3rd Android phone (Incredible, Charge, GN), and every one of these phones has had poor battery life. On average, if I'm playing around with the screen on, I'm draining upwards of 10%/hr, if not more. But if you properly calibrate the battery - which is VERY important - you should easily be able to get a full day's charge out of your phone.
There is a post on XDA about the 13 steps to proper battery calibration. Once I followed it on my last phone, my battery life went up at least 50%. You have to let the battery drain to 100%, then bump charge a number of times, then use the battery calibrator.

Try running without JuiceDefender. Constantly toggling data on and off (or wifi on and off) actually hurts battery in almost all cases.

Your results may vary, but when I used Juice Defender or Green Power on my Droid Charge, I nearly doubled the battery life. I haven't put it on my GN yet because my battery life is much better than what I had with the Charge.
No using JD or anything like that. Just the the phone do its thing. I don't even open the multitask button unless I want to switch between apps.

Gotta be a software issue with the battery.
Just this past weekend in Wash DC. Very strong 4 G market.
I had it fully charged off charger. After 7 hours without touching the phone even with google plus sign out, the battery went from 100% to 54%. It's like the phone was active a lot without me even touching it. No SMS/mms either. No emails either.
Know. I did same thing and put it on airplane mode with it 100% charged. After 7 hours on airplane mode it was at 98%.
So it's gotta be an operating system issue.
I tried it on wifi instead of 4G mode. And battery drainage was down to 72% after no use overnight.
Hi all,
i have a I9100, but the battery life is really bad, ihave to charge it up about 3 times a day.
i was wondering if getting one of thoses extended batteries (the ones which go in the phone, not the ones you plug in to the phone) is worth it?
and if they are, which one do you guys recomend?

You will get ~20% more juice with genuine battery. If you are charging your phone 3 times per day I don't think it's worth it.
P.S. What are you doing with your phone?

Wow 3 times per day? What`s your screen on time when you have to recharge? Maybe some Wakelocks?
However, a new battery the 2000 mah from Samsung can add some juice for about 2 more hours. At least for me it`s the case. With the normal battery I had about 16 h of juice, with the new one I can go with 18 h but of course depends on usage.
Hi, i get about 5 hours battery with about 3 hours screen time before I have to recharge, and is the any larger battery's then the 2000mh one?

I think that there is something wrong, 5 hours is pretty bad. Instal Betterbatterystats and look if you have wakelocks.
Ok if you watch HD videos all the time while your screen is on or you play games very often then 5 hours is understandable.
There are batteries that provide over 2000 mah but they are not Samsung certified and could damage your phone and they are significantly bigger.
Do you use any rom or any modified kernel?
So you are on your phone 6-9 hours every day How is that even possible?
You really should read some other threads before actuly posting a question about the same thing that has been repeated 100 times.
Its on the first page as well...

If you are using mobile data all the time, that is normal... You use your phone a lot! Genuine 2000 mah battery would give you another hour of use

Dude,if you're not using airplane mode ,then the problem with your battery is bad network signal.On your screenshots i can see that most of the time you have no network.When you have no signal ,the phone works to find it,thus eating the battery.
Hi, i only have airplane mode turned off for about an hour, and where it says the us no network signal is because the phone is in airplane mode

5h is really short. What r u doing? Playing all the time? I world consider to restock to ICS to check if changes you made could actually degradated power efficiency.
And for sure dont mess with CPU cores - by disabling second core you loose 50% processing power and gain very little teorethical battery juice. Android needs to work longer and harder to perform tasks.

Based on his screen shoot he's in airplane made 90% of the time... His mobile sign would be red if there was no cellular connection.
On the side note regarding the battery it might be that you might need a new battery try the 2000mah one it gives me 5hrs of screen time with around 20hrs of total use on AOKP. If not there are plenty of 3000mah batteries available that can boots your battery life tremendously and increase the bulk of your phone, and you decide. Btw based on what you said 9 hrs of sitting in front of your phone is not normal in one day. You don't even need bb to see what's causing the wake locks.... It's clearly the user the screen time on is consistent with the wake locks.

Batteries are gauged by how much voltage they are pushing in most tests. Though from my hobbies of electric rc cars, I've learned that batteries can change their voltages simply from a temperature change. While these changes may not be significant, they do represent differences and used to play a big part in my fifteen minutes charge cycles. It's harder to receive a positive rating in a cell that is low on power than it is with one on max charge. So if I'm down to twenty percent or so, I use my phone very sparingly. Has been pretty trustworthy for me over the years.
Either way, suspicious battery drain is usually a rogue application sitting there eating resources as the phones we use do seem to monitor battery life pretty good compared to the old voltage meter methods.

I assume you had a good signal everywhere you went? Nothing drains a battery faster than being in an area where there is very low or no signal. It constantly tries to connect and it will KILL your levels very fast. I see this quite a bit in my work place. Employees with Sprint and many times AT&T will complain about their battery dying at work only to find out the phone was constantly searching for a signal.

You know, I totally forgot about that. I used to have that issue with Sprint myself. Killing the data would eliminate TONS of battery usage when I was at work. Now that I'm on Verizon, there's never much problem. But he's completely right. If you're not getting a quality signal your phone may be searching and that can be an all day thing which just eats a battery alive.
I am in a near perfect signal. I'm pretty sure its has nothing to do with coverage. What's strange to me is the phone immediately dies. It will be at 50% and then the screen goes black and won't come back on. Once I plug it in the phone finally comes back on and is at zero.

Sent from my DROID2 using xda app-developers app
Basically, the more you drain the power before charging, the less charge cycles the battery will have. Someone who charges at 75% compared to someone who charges at 25% will have more cycles over the life of the battery. I can't remember the exact numbers, but there's been plenty of studies on the issue. And if I'm correct charging at those numbers, the 75% will have more than twice the charge cycles over the life of the battery. The biggest battery killers though are actually higher amperage charges. One study showed more than five times the life cycle at 3.7v per cell compared to 4.3v. And the charging required to power the higher voltages actually cause more damage over time than the extra mah output is worth. The HTC one has a decent setup and the stock charger doesn't over feed the cells. But in not sure if it will make it to the 700 charge cycle that a two year contract may leave a user with.

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!
Sent from my T989 doing Jedi Mind Tricks
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.

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.

On Jedi or on CM10.2? I don't know if Stock lets you use Dual Carriage or not. (Probably does, doesn't show it).

Areyoucrazy, 5-6 hours of on screen time or total? If that's all you get even with screen off, something is probably keeping your phone awake. Get an app called better battery stats or gsam battery monitor to figure out what is keeping it awake.

It is the total battery hours. My screan time is barely 1 hour.

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.

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

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.

I will try the cpu spy again. I remember doing it before and it was almost inconclusive if there were things I could control vs system related drain that I couldnt control.
I am currently on a new OEM battery (2 months old) and several ROMs later,. Some ppl claim they get best battery life, I just want to mirror exact same ROM, kernel... even the apps they have and their refresh settings if I need to.

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.

wow, and i thought mine was bad... i have my screen on alot and play 3d games, i guess im doing good. running slimbean.
I do believe that the battery life on this phone is not the greatest, a spare 5$ ebay battery in the wallet keeps me worry free
