Okay so I have always had bad battery, but this is a bit extreme.. I am using Suckerpunch build 40 and Serendipity and i am heavily undervolted. I got about 6 hours of moderate usage out of it today before it died. (some gps usage, browsing xda, 40 texts back and forth, internet browsing) I am using JK3 modem with HSUPA enabled.. but i feel like this battery drain is a bit excessive. Any ideas?
If it isn't an app that is polling too much or it isn't a low signal issue, then I could only blame the hardware for being defective. That combination, even with the 1400 overclock has yielded me easily over 24 hours with moderate usage. Even now, I have gone 6 hours with 80% remaining.
Okay, it's caused by one of three things as I see it. And I bet your issue is the 3rd reason.
1) Bad battery, get a new one, but probably not the issue
2) Applications going out over the network a lot, especially if you are usually in the worst area, where you barely get reception, but get a slight amount... this one is tricky because I am yet to find an application to map out how much network an individual application uses over time. Some will monitor which ones are going on the network and some will monitor total network, but not break it down over time per application.
3) A background system application, or user one, is using more CPU than it should and sucking your battery. I had this issue, and at it's worst I was getting only 2 hours of battery life. I finally realized my phone was running hot for no reason. Because of this observation, I got the best application I've found on the marketplace for this, SystemPanel (The paid version). I hate buying applications, but this one saved me money from getting a new battery/phone. System panel will monitor your phone for a given period of time and break down the top apps by CPU useage over the last so many hours (you choose). What I found was that a system process (kswapd0) was sucking 24% CPU. This doesn't mean it accounted for 24% of the application total useage, it means it account for 24% of the CPU useage, which is different because if total application useage is only 1% then 24% of 1% isn't bad. But, 24% of the CPU is. So, I reflashed and all problems were fixed. Battery life could go 36 hours or longer with little useage and ksawpd0 was down to around 1.4%. Later I had bad battery symptoms again, but not as bad (like yours 6 hours and dead), and I checked SystemPanel and guess what, kswapd0 was accounting for 6%. I had to flash again. It's fixed again, not sure why kswapd0 does this, but
What I guess I'm trying to say is get SystemPanel and find out why your battery is dying. It also graph's the phone's drain. Look at the slope of that graph and see if it's extreme. Time when you are using it for internet should be really bad, but the idle time shouldn't be. I get around 36 hours idle time like I said, and if I were to just play robodefense or use the internet non stop I'd probably only get 2 hours of constant useage.
You might have wifi enabled all the time? If you have wifi on when your not connected to a wifi network it drains your battery like no tomorrow.

Seems like the system process idea might be my problem, because i know that wifi is not on, i usually disable it or juicedefender does it for me. I'll go through my normal day of light usage and then post a picture of my battery snap graph. If it isn't better by a run through again today then i will probably reflash like you suggested.
Calibrate.. Charge up to full.. Boot recovery delete bat stat.. Unplug ...discharge.. While off charge up to 100 ..then use

Poor signal is another culprit, especially when using non-captivate modems.... this will cause rapid battery drain. I had one location where my phone would only last 8 hours with no use, because of signal.

Let me know your results!
Try changing the ROM/Kernel combo. All kernels don't go good on all hardwares.
Yes I'm also eager to know what you find, as I am on the latest Phoenix with Firebird 0.8 and JL3 or 4 not sure which.. My battery life just plain sucks, will be getting that app now to monitor.. Anyway let us know what you find asap!
By chance have you tried a different battery. If memory serves me correct, some captivates were shipped wit a bad battery, and they were being replaced under warranty. Just another troubleshooting step.

I'm also experiencing some bad drain on suckerpunch #40 with di1igaf's stripped 5.6 rom.
after flashing, restoring all my apps, syncing my google account, and setting an undervolt, I let my phone idle for 2 hours. over those 2 hours I lost only 1% of battery- I was so excited! this was the best battery performance I'd ever had.
then, I left the phone unplugged overnight and I lost over 20% in 8 hours. I have no idea what happened!
I have been using watchdog lite to monitor processes- the only thing that is using up any CPU is "android system" which is usually taking up about 10% of my total cpu- does that sound normal?
I thought this might be a problem with the flash so I re-flashed but the issue persists. I have been using the same app/widget setup for a few months now with several different ROM/kernel combos and have never experienced this kind of battery drain. Not really sure what to do at this point...
(edit- I have wifi set to sleep with the screen off so this shouldn't be the issue and I flashed from 100% battery and cleared the battery stats)

I had the same issue with that kernel. All kernels may not go well with all hardware. U cud try the kernel I have in my signature. A couple more folks tried the same, and are happy with battery. Idle drain (overnight, with wifi turned off) is about 4% per 7-8 hours of sleep time. ROMs too are known to drain, but in this case, I would strongly recommend trying out kernels.
After battery calibration, I would strongly recommend atleast 2-3 full charge cycles becoming coming to a conclusion that battery drain is high.
thanks for the advice. i will go through another 2 or 3 cycles, then I think I will try the speedmod kernel as I have had success with that in the past. if i'm still having issues I will definitely give that new xcal kernel a try.
the weird thing is the drain seems to be going up and down. right after I flashed, I was losing about 1% per 2 hours. then overnight it was over 3% per hour. this morning it was more like 1% per hour, but now it is speeding up again.

Speedmod didn't go well with my hardware. I have more drain using speedmod than I have on xcal.

I've tried everything: JK3, ZNKP1, JK4, JL2, JL3.... znkp1 gave me the worst battery honestly, JK3, JK4 or JL2 were the best.
I think I'm going to accept my less than a days worth of battery and carry around a spare with me. Any way here's my usage yesterday. some light usage in the morning (pre 720 am) with idle the rest of the day until 210 pm
Ok i found out my battery stats are resetting at least every boot. Would this be detrimental to battery life?

For good battery life, I recommend using Precsion Rom 1.01 with Speedmod' kernel. I am getting amazing battery life with it After 2d 5h 10m 25s, I am still at 27% battery life.

Hey guys,
Just wanted to share a few things I stumbled upon recently. The first thing we usually notice is really crappy battery life when we flash a new rom. I tried using a bunch of stuff like juice defender etc. I recently used the MIUI rom and then came back to dexters 1.3. Anyways this time I used a small app called Battery Calibration. Basically what it does is delete the batterystats.bin which is generated by each ROM. Charge till hundred, use the app and then discharge completely once. Then recharge the second time. I noticed a 200% increase in battery life on dexters. I dont use my phone alot but this was with around 1 hour talk, 2-3 hrs one and off browsing, 30-40 texts, a few photo's etc. It lasted 1 d 14 hrs when usually itd last around 20 hours. So you guys can give it a try.
Another thing, juice defender works by toggling the data connection. Now I use Edge as mobile data and wifi at home. I realized my battery lasts as long as if not more than with juice defender. Ive come up with a theory, that apps which disable the connection takes more juice because with every screen on the radio has to search for the network, wifi signal and then connect to it. Leaving my data on all the time, or wifi on all the time does nothing at all to the battery in the idle state. It only uses juice when there is data transfer. I left my wifi on all day with autosync off and it cost me 2% juice. Anyways give these tips a try. Worked for me well.
Calibrate your batteries after each flash and dont use any third party monitoring apps. And set your wifi to sleep with the screen, tell me how it works out for you!

I use both those actually 3rdstring turned me on the to Battery Calibrator, but I purchased the Juice Defender Plus b/c it has the ability to customize its toggle for each individual app. Enable, Enable/screen off (good for online music or something like that b/c your screen eats battery and is chief in temperature hikes), Disable or Do Nothing. Their is a Juice Defender Ultimate, but has a lot of things that XT720 doesn't use or need like 4g toggle and stuff like that.
The makers of Juice Defender have another app called Juice Plotter that shows you battery use. Was useful for a week or so but it is another service that is running in the background all the time so I uninstalled it.
There is a nice monitor app that I have had since day one called Battstats and it is a simple widget that has a low memory footprint when running in the background but it show the charge %, Volts (4.2 +/- is full charge) and temperature (c/f). Small 1x1 widget so it doesn't eat a whole lot of memory and I have found that it is fairly accurate.
One last thing is if you are overclocking, make sure that it is set right or you will eat more battery than it is worth, not too mention stability issues. If you set the vsels too low, the phone will reboot now and then on its own. If you set it too high, then it eats unnecessary battery. I have mine at 1100/ 74 and is totally stable. Volts might be a little high, but it works for me. Depends on what you want though b/c overclocking makes you phone faster but kills battery power. Underclocking slows things down but uses less battery. SetCPU can set up profiles for this.

hmm.. i tried battery calibration with your method several times and my battery life can never reach what it has before rooting. It could last 80 hours typically on standby mode. But after installing khals or dexters or 2.1 strike backs or miui, or even restoring my old rom, my standby duration never lasts more than 60 hours. Only thing i look forward to now is Cincinnati bells update or beta5 miui

You need to discharge it once completely till it turns off itself. Did you do that? First charge till 100, then use the calibration, then discharge completely doing your normal stuff. Then completely recharge Im sure youll notice a change. I did

Hey 3rdstring. I had my setcpu settings like that before I stopped using it. The reason was when you set it low at screen off and you get a call it lags real bad. Like when you are trying to accept the call by swiping the lock to the right its lagging, even the ringer skips abit. I also noticed with the cpu set low to 250 the phone has trouble finding antennae and signals. I've seen no increase in battery life with either set cpu or juice defender. Does this happen to you?

What are your cpu settings bud? I just redid mine for now and i will see how it does. I'm running 1200mhz really stable for about 2 weeks now on miui without setcpu. I just noticed also in settings/system/about phone it has my phone model listed as Nexus S, I was wondering if that is what it's supposed to be running MiuiV3. I think it's messing with my setting options in setcpu.

Lol, sorry it isnt working for you guys. One thing though when it completely discharges it takes a lil time for it to have enough juice to turn on. So it not like the battery got screwed on anything. Im still getting a battery life of 1.5 days when before It was extremely bad like 20 hours.
So I've had this phone for a week now. Its a nice upgrade from my infuse 4g. But the battery life is killing me. I've tried every Tom.available specifically for the skyrocket and even the one kernel in the dev section. My brightness is 15% and I use juice defender set to every 30 min. I listen to Pandora for an hour and it drops 20%. Yesterday it was dead in 6 hours. Its to the point where I'm seriously considering going back to my infuse. Has anyone else had issues?

Currently have juice defender, 0.2 kernel (didnt update and probably wont for now), and a few apps frozen by Titanium Backup. If I hardly touch the phone, it would last 41 hours. With medium usage, (Wifi, web browse, using poweramp for some time, calls, emails, etc) It would easily last my entire day.
What apps did you freeze?

I have JuiceDefender Ultimate set to balanced, I have only the clock widget running, I have GPS running continuously, (I use Wifi occassionally), I have screen set to about 50% and with very normal usage, the battery is at about 20-25%. I have a good number of email accounts and they are polled constantly, notifications are normal (phone settings), I use the Market app and the browser a number of times a day and I hear the occasional podcast. By the way, listening a podcast for about 1 hour (I use BeyondPod and earphones) results in minimal battery usage (about 2% for an hour or so).
So, I have to say that I am quite happy with battery life.
I know what you mean.
I had a stock skyrocket running in a weak LTE market in New Orleans and it would last like 8 hrs then I rooted and frooze all the bloat ware and de-installed a lot of app that were always using the web. I manually set my screen brightness. And changed the launcher to go launcher. Getting 18-20 hrs lots of moderate usage lte and all.
Yea something is wrong. I don't even use juice defender yet my phone last all day wit like 20% when I get home at 9. I use it to talk at least 3-4 and moderate usage for internet and am in wifi a lot. Youtube umm often..Defective maybe??

How do you turn off LTE?
look in settings, about phone, battery and see what is using all your battery. Battery life is very good on the stock ROM, rooted or not. You might also want to install Traffic Monitor and set it up for your billing cycle properly. Then watch for a few days to see what apps are using data. I do not recommend turning off LTE.
BTW there is already a very good Freeze list of Apps...

I was also having very low battery times on my SR to the point it was draining about 5% every half hour. I checked everything and everything was set properly. Yesterday was ready to pack it up to exchange it and thought I try restoring the phone. After restoring it, I now get excellent battery life. I'm getting about 1% battery drop every hour. Today tested throughout the day and listened to some music, some web browsing, a few FB posting, a call for 20 minutes and have 95% battery life left.

I've had pretty bad battery life here in the DC area (LTE is available here). It'll last about 6-7 hours with very mild use. Maybe I should restore it?
What did you do @ElCamino to reset it? Maybe I'll try that too (though I'll hate having to set it back up again).
Also, I turned juice defender back on today, and I've noticed that it seems to be keeping the device "Awake" even when the screen is off. I have it on "balanced." Can anyone give me a little advice on setting it up correctly. I can't seem to get it to let me open more granular settings.
So I am starting to wonder if there are some defective units being shipped. My wife and I both have a Skyrocket. Mine is great, been using it for 13.5 hours today on medium usage. I currently have 63% battery life left. I am completely stock, no juice defender or any other like programs. I even had No-LED installed and used my flashlight app for about 5 solid minutes.
My wife on the other hand has the exact same setup as I do. She complains she barely gets through half a day with medium usage. I charged up her phone earlier today. 7 hours ago I took it off the charger. She has used it with very light usage in that time and it is down to 60% already. When I say light usage I mean sitting on the table for at least 6.5 of those hours. Often she charges it up while watching TV at night. Takes it off the charger when she goes to bed and by morning the batter is at least half drained.

@jslanger I went to settings>privacy> and choose Factory Reset. Yes i know that you have to reinstall and setup the phone, but I am glad I did. Battery life has been great. I'm not in a LTE area but like mentioned battery was draining quick before.
Also I wouldn't recommend you use a back to restore, just in case that something with OS setup from Samsung causing this.

Search for Titanium Backup in the Android Market. You will have to check and see if it requires the pro version to freeze apps.

just to help you guys possibly, i moved some APPS to my SD card last night, at work i noticed mediaserver was second in my battery list and my phone was draining faster than normal
after moving the apps back to the phones internal, the drain seemed to stop, i also wiped the sd card just to be safe as i usually stream pandora anyways , but just another option to look out for
Weird....
So I've been closely following my battery life because it kind of sucks.
I had great battery life at home while on wifi over the weekend...about 18 hours no problem. I recharged it today at work, and was not getting great life during the day while on LTE/4G
Got home, turned on wifi, and the battery drain completely leveled out. I also noticed that while on cellular, the "Awake" bar is solid. As soon as I'm on wifi, it was able to not be continuously awake.
Not sure if anyone can comment on the reasons that this would be, but usually its the OPPOSITE. I really dunno why this would be.
Any help is appreciated!
Here is my battery life. Rooted and haven't froze any of the apps yet.
I know i

So I just got this thing as an alternate exchange for the mytouch 4g and I like the phone .. but the battery on this one suuucks. It drops ABOUT 10% an hour and I havent really used the phone much at all.
When I look at the battery stats it looks weird to me .. the screen is always the lowest thing using the power by a lot, and its ALWAYS the system idle and standby that use the most battery by far .. which seems kinda backwards to me .. I dont know .. so thats why im posting this here.
My battery seems to only last bout 10 hours or so with light usage... which is way worse than any other phone I have had which is the mytouch 4g and the Galaxy S II.
Today I have sent 2 sms and recieved 2 sms and have no calls at all. I did check facebook Three times to see some posts so a few minutes there. The screenshot is from today and Im already under 50%. I havent turned on the wi-fi. GPS is off and I do not use bluetooth at all. I also have the screen brightness at 25% and this is with a normal clock speed as well. I have turned on the screen several times just to look at stuff... but that doesnt explain the 3% screen usage and the freaking 48% of standby and idle.
someone thought battery .. but I dont think so with how the phone is saying that the usage is spread out. Does the screen on this phone really use that little power and the idle and standy drain the battery like that???

Each person's phone will have different statistics. Different ROMs and kernels will give different results and the kind and number of running apps. Those percentages don't indicate the amount of drain (current) each one is using from the battery. Are you using a battery management app to keep the battery drainage minimum?

I am not using anything like jusice defender .. I do kill the services in the background a few times a day with system panel app. i am running CM 7 on here .. so im sure a lot of others are as well.
since im new to the phone im not sure if this is normal or not for it to die this past without it really being used much. system panel did say that a few apps used battery .. but one was at like 8% and the others were well below that.
Try using Weapon 3 with Faux123 kernel.

Got to remember it is dual core and will use more battery power.
My current stats after only 11 hours of use:
Battery level: 12%
Cell standby: 34%
Phone Idle: 33%
Wi-Fi: 31%
Wi-Fi Calling: 3%
Display: 2%
Haven't used my phone for most of the day. I sent 3 or 4 text messages, and was only away from my apartment for 30 minutes. BUT, this is shortest amount of battery i've ever seen this thing suck up. I usually range between 16 to almost a whole day before having to plug in, and that's with my being away from the house and browsing on data for about an hour and a half (2 breaks and my lunch).
I think the phone has it's own mood swings, lol. At least it charges pretty quickly!
I have had lots of variability in battery life between different copies of the g2x and different roms. I have tried almost all the roms on these forums.
My personal experience is that there are good and bad versions of the g2x out there. The bad ones tend to overheat and shutdown. These naturally have poor battery life.
Also, I have noticed that the g2x does not handle areas of poor mobile reception well. It tends to drain battery and overheat in these instances as well.
Finally, I have found LG 2.3.4 based Tsugi (with stock kernel) is far and away best for battery life. Might be improved code from LG, might be the baked it toggle2g app... but I am very happy with this phone under Tsugi.
oh wow .. i will have to try some different ROMs then it sounds like and see if that helps

absolutely .. but I also have a Galaxy S II and it uses nowhere near the battery as this thing does at all .. and usually the display is what uses the most power and idle and stanby are what uses the least .. and the G2X is opposite of that . which doesnt make sense to me cuz if its idle the the screen is off and I have it underclocked with screen off .. soo I dont know why that would be using so much battery.

see yours looks like mine does . except I didnt have the wi-fi on .. so maybe this is typical for this phone to use so much battery when its not doing anything. i just cant imagine how the screen uses so little battery though and the idle so much.

I could be wrong but I think the % is based on the time and not the battery.
Cell Standby 34% of the 11 hours = 3.74 hours on not 34% of the battery. If your total all your numbers together it would be 103%.

You are correct GTWalling. Those figures are based on how much time each event is using the battery, NOT How much battery each event is using.

If you knew how much current (milliamps) each event/process is using then you could calculate how much of the battery's capacity it uses by taking the total time X percent of time battery used X milliamps. The battery is supposedly 1500 milliamp-hours. milliamps used/1500 milliamps X 100% = percentage of battery used by that event/process.

Hmmm interesting stuff here ... Thanks for the replies.
Sooooo if that's not how much battery they are using then is there a real good app to see what apps or system apps are using the battery?
I have looked at the market but none looked very good.thanks

First off, I am loving the phone. It is such a massive leap from the N1 I had been using. While I expected lower battery life, I did not expect to run through 70% of the battery in 4 hours with moderate usage.

I have heard of people getting far better battery life, and have tried the various methods, from charging to 100% then turning the phone off and charging again to 100%, using juice defender ultimate, and even resorting to factory resetting the phone. Still I can't get any kind of good life out of the battery. My question is should I try and get a full replacement for the phone or just the battery? I've only had it sinceblast Thursday, so I know AT&T will happily exchange it, but if yall think it's just the battery, I'd rather just replace that then the whole phone.

Have you found out what is using your battery?.. Even before I rooted and all the other stuff was getting at least 10hr.. now Im getting 24-28hours...
Are you running another ROM other than stock?
Didn't want to root if I needed to return anything, so I am running stock currently. Looking no app seems to be running away and draining all the battery. Everything looks the same as it did on my N1 in terms of what's draining the battery, which is what lead me to believe it's a bad battery possibly.

I was concerned with battery life at first as well. When I first got this thing I had to plug up 9 hours after I unplugged. So now I am near 30 days with it and the battery seems to have leveled out enough for me to be happy. I got 16 hours on it STOCK no ROOT the other day without plugging in, was at 10% when I finally plugged in. Yesterday I activated Juice Defender again after getting some questions answered. I got 17 hours without a plug in and was still at 25%, so i probably could have gotten 20+ hours if I needed it.
So I am happy now 17+ hours is plenty long enough for me, I always plug in at bedtime anyway.
I'm wondering how many people who are reporting battery issues, if they have calibrated them. Charge your battery all the way, use the phone until the battery dies, then fully charge. This will give a more accurate reading as far percentage used.

There is a new ROM Piret RC1, the battery life is amazing, it has a different Kernel as the one with TPC has it';s problems.
RC1 is clean fast and in 2 hours I used up 4%. Then turned every possible service on used it up like crazy to drain the battery, installing/backing up/ flashing new rom and it took 2 hours with heavy usage to drain from 17%. Just to compare last night I had a TPC ROM and was on WhatsApp for about an Hour and battery went from 85 to 34 %.
Re: Returning the phone.
First once you root you can the same way unroot, make sure first you install a stock ROM.
My friends have the same problem, one with this phone, and others with android phones in general, don;t waist your time returnig. To be safe you also have a year to send it to Samsung to get fixed if there is something wrong with it.
Basically, running apps will kill battery, location services kills it the most, sync not so much, heavy use of data does to (I have LTE plan). Use power saver to start at 70%, configure it right, use the CPU app to manage the speed ondemand.
Most important don't frick out, the andoid phones are like that, the major difference is that Iphone does maybe 20% of what android phone does in standby and many things are not available on Iphone, so the battery is better. You will not get more then a day of use on android if you use it to your benefit. 28H is mostly standby, no sync, no internet usage, just moderate. I used to use Iphone heavy and battery would not last a day.
Get a good data plan, don;t use WI-Fi unless u have too, when syncing with the car plug it in the charger, spend extra $10 get a Samsung cable from them, don;t go for cheap 10 dollar once or even 1 dollar once from China, they are very slow to charge. My cable from the box take 1.5 H to charge to 100.
Hope it helps, please don;t quote me on anything, this is purely based on research and one week usage and trying different things, it's strictly my opinion, don;t expect your phone to last like they use too, it's 21st century and techno in it is overwhelming and needs power. Keep the phone have two cables and enjoy!
This is my first smart phone, after 20 plus years of having cel phones. I try to read before posting any questions.

good habit to get into thanks for that....the search button is your friend.
I have been reading on the battery issues, long before I posted. I have done everything from calibrating, to using juice defender ultimate, to doing a ritualistic dance to try and coax more battery life out of this phone. Still with nothing but 2 phone calls and one quick spelling look up, dead within 8 1/2 hours.
I just got my extra battery and charger from samsung in today, already fully charged up this battery and will see what it can do for a few days. I'm hoping my problems are just a random bad battery. I also factory restored and am running bare minimum on apps just to try and remove all variables. If there still is a problem I will exhange it for another one next week. I just hope they still have some white ones in stock

My battery went completely dead too. I returned mine. Black model though. New one is doing okay so far. Better since it doesn't report 100% battery until a reboot...
Finally went and exchanged it last night. So far I have gotten 9 hours of battery life and am only down to 70%. Better than before, but the vertical lines on the screen are worse on this one than the last.

I have almost the opposite "problem." Not that I'd call it a problem just yet. I had my phone running from about 10am till 1am yesterday. I went to bed and plugged the charger in and it instantly said "battery charged 100%. Remove charger." 15 hours with no drain at all? Granted, I didn't do much with it yesterday but send about 20 text messages.
Going on 32 hours+ battery life and no vertical lines.. bought it when it came out Nov6....

30% in 9 hr's? you need to see what is killing your battery... unless you play games or on the net all day.. that is not good at all..
I lose about 1% an hour..
I don't know what you smoking man but i tried his rom and never had issues. Let me tell you I Have ORD so my suggestion will be based on my usage rather than prediction. I have tried most of the themed/tweaked roms. Don't like stock rom.

I'm getting pretty good battery life on bean R2 (I easily average 20+hrs). But no matter which ROM I am on, no matter if I'm getting great or poor battery life, I always start to get on edge once I have dropped below 70%. I start to think, damn there goes battery today. I realize I still have 3/4 of my battery remaining but I just feel this anxiety that my phone is not near full charge.
I let it drain to empty a couple times a month but it becomes almost unbearable when I get down to the last 1/3 of my battery life.
Is it just me?

sounds like you need to turn off percentages. I had this problem until i turned it off. Now i have to go a few steps further to find out what it actually is and that makes me not care as much.
My battery life is HORRIBLE.
Have you tried using an app like GSam Battery Monitor?
I've been able to track down a few issues with that app, including one where I needed to wipe my cache to stop my internal sd card from being continuously scanned.
I always get over 2 hours of screen time over the course of a day. Currently using AOKP Jelly Bean, and it's still the same!

Don't drain your battery. People really need to stop thinking these are the old batteries of yesteryear. Draining your battery will cause it stress and lower it's overall life and charge over time. Draining your battery is causing exactly what you're trying to prevent. Best practice is to let it get to 15-20% and then charge.
On topic, I get anxiety about battery at around 70% too. Mostly because it seems to hit that point pretty fast, but then can last the rest of the day no problem.
Have fun with your new phone and keep a charger on stand by! If you use your phone medium to heavy use you should get to the end of your work day and you can charge it when you get home. Did you get your sd card issue resolved?

Ive found that having a spare battery always charged, along with the spare battery charger handy so I can charge a battery while using my phone, works great for my mental 'battery issues'!
On Synergy 1.3, I have AMAZING battery life! Can usually go 2 days between charges if I wanted to...Unplug the phone at 8am and at midnight, I'm rocking 50-60% still, depending on the day.
GSam Battery Monitor can help find apps that are abnormally draining the battery...But I've found that it too can cause the phone to get stuck in a wake lock...So I don't keep it installed, only use it if I have a weird battery drain issue.
I'm the same way, if not worse. I constantly look at power usage (in miliamps and %/hr). I should just remove all battery widgets and percentages, I almost always have enough battery, just paranoid.

That's weird how they do that.
My phone does the same exact thing with the big 4000+ Hyperion battery. It drops to 70% in what seems like no time at all, then three hours later it is still at 70%. The battery gauge obviously is not very accurate at all.
Right now, my phone has been on for just under 10 hours and says it is at 40%. if I just let it go (I charge it every night) it would run all night and still be at around 40% tomorrow morning.
I am the same way after just installing synergy 1.3 on saturday I have been constantly checking battery percentage. Anytime I change anything I get obsessed with it for a while.
This is what I like to see! Used to not be able to get close to 3 hours screen on.

Battery
I've read about the new batteries and not letting them completely discharge, instead recharging when it gets to 15% or so.My battery life was awful, if I was at 45% or less I needed to plug it in before going to bed. This was a daily thing, I charged my phone every night, Well I forgot the other night and woke up to a dead battery. I plugged the phone in and turned it on while charging. I charged it to 100%. This was 2 mornings ago (not been charged since) and I'm just now a 46% with normal usage (for me). I just thought this was interesting and wonder if anyone else has experienced this or can replicate it.
Battery Life
I'm getting smoking battery life, been tethering a good 2/3 hours and been on the phone and answering email add day and checking this site. I am on 1.5 Synengy, and using the Snapdragon CPU script that was posted in one of the forums. I can post the link as I don't have a large enough post count, however I would search the forum and find the mod and use it.
It's amazing, I'm at 51% battery and have not plugged in all day. I unplugged it at 7:30 am Arizona time and it's 4:30pm AZ time.
Try it, it' works.

You can also change the processor speeds along with the battery save options.
Make sure you read the OP VERY CAREFULLY, it's where all the details are to run the script.

Wow, your cell standby was eating you up. Hope you got that fixed.
As far as battery life, I feel mine is average to good. Cell standby and Android OS account for only 9% and 5% of my battery, the other 52% of it used up is screen.. so I think thats pretty good numbers to see.
