[Q] EXTREMELY horrible battery life

I've read on many reviews (Gizmodo, Engadget, CNet, etc) that the battery on the DInc is not that great, but mine is incredibly... bad. Examples:
I browse the web (mostly mobile websites with not many images, flash etc) for ~20 mins and battery life decreases by 20%
I leave the phone ON overnight without charging and it's at 2% in the morning. When I went to sleep it was at 60%
I turn the phone OFF overnight without charging and it dies (I couldn't turn it on, had to charge for 15 mins even to turn on). When I went to sleep it was at 30%
I've also heard both that ATK is useless and that it's a gift from God for battery life. I'm running the Pro version killing every 30min and it's not helping that much (maybe 30 mins)
Is my battery defective, or are other users also experiencing this bad of battery life? My DInc is SLCD, running UberZ RC1.2 with stock battery.

Im guessing you havent had your incredible for more than five months right? Considering htc didnt start making them until the late summer. Anyways I do know that desire z ports often use up quite a bit of battery in their displays. However considering you left it on overnight and it was nearly dead I dont think it was that. Something you can try is going in the advanced menu on clockwork mod and erasing battery stats. This seems more like a defective battery though. New batteries can be bought for fairly cheap and if you do decide to get a new one you can get them for pretty cheap. Touchpro 2 batteries supposedly work with the incredible as well

Make sure you turn off GPS, WiFi, Bluetooth, etc. when not in use.

Yeah, I've had it for about a month. I will reply after erasing battery stats and trying it out. I'm not sure that I would use a Touch Pro 2 battery - seems like too much of a risk. However, I have seen Evo Batteries on Amazon that supposedly work with the Dinc. Do they?
If it helps, I use widget locker, with: extended controls, fancy widget, nexus revamped (with a lot of spawns on slow) and 3 sliders.

I have, I barely use BT or GPS so they're almost always off. I only turn GPS on when I'm charging and I'm using location based apps. 3G is off at home and Wifi is off on the road / at school and when I'm not using the phone.

What you might want to try doing is uninstalling widget locker and charging your phone all the way up. If after uninstalling widget locker the drain is still significant it may be the battery. And from what I read, the evo battery works with the incredible, it just makes the back cover fit a bit more tight.

OK, I've wiped battery stats, though it's only been a few mins so I can't tell yet. I'll reply in a couple of days. Also, can I just disable WidgetLocker instead of uninstalling it?
I also have a silicone case that hooks on the front edges, will an Evo Innocell (with back cover) mess with that?

I dont think an evo back cover would work for the incredible as they are not the same dimensions.
And btw touchpro 2 battery will work with the incredible

I just moved to an Incredible from my Droid 1 and the battery life is horrible compared... I got it as a replacement for having so many issues with my Droid but the battery life is almost unusable I'm running CM 6.1 and I wiped my battery stats, drained the battery then let it charge overnight powered off and I still get really bad life... I think a lot of it may have to do with the stock 1300mAh battery compared to the Droid having 1500mAh but I'm not sure... I'm considering the 3500mAh sedio battery but $70 bucks is a bit steep atm

Thanks for the great find, though I was thinking about maybe one of those seidio 3500's. Though since it's so cheap, I'll probably buy it

I've seen one on amazon for ~$25. Not seidio though. Reviews were meh.
I don't think its the 1300 mah vs 1500 mah. That's less than 20% (so like 10 hrs vs 12 hrs).

Didnt see the part about disabling widget locker, sorry.
Yes you probably can disable it just make sure it is definitely not running.

Don't run ATK. Android manages apps by itself. There's a whole lifehacker article on it.
Sounds like a run-away app.
Hmm, turn your screen off and let your phone sit for 5 mintues. Go into Settings > About Phone > Battery > Compare uptime vs awake. They should be AT LEAST 5 minutes apart.
If they're not, go to the market and install "Watchdog Task Manager" (<--this is NOT the same as ATK, again, lifehacker article on it) to monitor rouge apps.
Hope this helps!

My phone has been sitting and charging for ~2 hours, but up - awake = 5:12. Is it normal?
Great work, by the way.

There is no normal.
Up time is the elapsed time since you turned your phone on. (i.e. after the phone was completely off, not just screen off/sleep mode).
Awake time is suppose to only be the time your phone was actively being used (i.e. screen on).
So, Up time minus Awake time should equal the time your screen has been off, (i.e. asleep).
If Up time and Awake time are equal, and you've had the screen turned off (i.e. asleep) for part of that time, then you have some app that's staying active durning sleep mode.

I might reboot when I go to sleep tonight and do nothing on the phone, then check uptime vs awake when I wake up.

1300 Mah battery is not acceptable for a phone of this caliber. There are alternative options for battery's. I use setcpu to underclock the proc and I've seen a dramatic increase in battery life.

I've been using Setcpu as well, with 998 mhz while charging, 245 when screen off, 245-520 when hot or <20%, and 245-850 otherwise.
Agreed about the battery, HTC and VW probably want to force you to spend more on extended batteries.
Too bad, otherwise it'd be a perfect phone.

HTC usually seems to skimp on the battery. It really hurts their reviews but I suppose they can save costs and assume people can always buy an aftermarket battery. I don't agree with it but it's their business.
Anyway, that does sound like abnormally bad battery life, but I have a question - are you in a poor service area? If so, the radio might be working extra hard to acquire a signal. Even when I had my dumb phone Samsung alias (which had decent dumbphone battery life) I would experience complete battery drain if I left it in my poor coverage basement overnight.
Also, when you're browsing the web and such do you use wifi or 3g? I notice that when I continuously surf with 3g the phone starts to get warm, especially in mid-poor coverage areas. When the phone gets hot the battery gets hot, and when the battery gets hot it drains much much quicker. Of course, high power usage generates more heat so I'm inclined to believe our 3g radio consumes way more battery than our wifi radio.
Over the months I've combatted poor battery life by doing the following:
1. Purchase aftermarket batteries. I've fallen into HTC's trap. I bought an evo battery which can last me of 6-7 hours of wifi awake time and 4-5 hours of 3g awake time. I also purchased the extended 2150 battery from Verizon which I can get up to 10 hours of wifi surfing and 5-6 hours of 3g surfing. Back when I was on stock 1300 I would get 3-4 hours wifi surfing and 2-3 hours 3g surfing.
2. Install an undervolted kernel, if you're into that sorta thing. One of the main reasons I'm able to obtain the numbers above is due to my kernel which undervolts the processor. I use adrynalyne's experimental undervolted kernel and it works without a hitch. I use it in conjunction with setcpu so I can have a screen off profile which underclocks the processor to 128-384MHz while I'm not using it. The only caveat to using this kernel is you can only use the conservative CPU governor. This means lower clocked speeds will be preferred as the CPU actively scales itself, and will take longer to ramp up to the higher speeds. But we're talking about maximizing battery life so that isn't necessarily a bad thing.
3. Try to keep screen brightness down, minimize usage of other radios (Bluetooth, GPS). Sounds like you already do this though. Rogue apps have also been discussed but if awake time != uptime then that's usually not the case.
As also prevoiously mentioned, it is possible you have a defective battery and should go about getting a new one from them though I'm not sure how that process goes... someone here is bound to know though.

I definitely stand behind adrynalyne's experimental undervolted. You can find a link in the kernel thread on the android development section of this board. He makes a sense and AOSP version. I've tried some of the newer ones like Chad's but I love the longevity and stability of adrynalyne's too much to live with the switch. As aforementioned, if you decide to use setcpu, make sure to only use the conservative governer. Ondemand will cause it to freeze! Otherwise it's rock solid.

How's your battery life with low-med usage?

I'm getting some really good battery life with light usage so far.
1d 3h 33m
Edit

I m getting similar results, light usage I unplug at 7am and plug back in at 1am with ~50% battery left.

This screenshot doesnt say much, tap at the graph - that the screen to show off

WIFI seems to be much better. With my LTE on I can barely charge the phone LOL. I wouldn't trade 20 Mbps down for bettery life.

I'd say my experience has been the opposite of what's been reported. With low to medium usage, I'm lucky to get 8 hours. I don't think I'm doing anything wrong. I use setCPU to put my phone in battery saving mode and underclocked all the way when the screen's off. I kill apps whenever I notice a lot are running. I dunno. Coming from an iphone, I'd say my battery life has been horrible.

I've never been an iPhone fan, but since the iPhone 4 the battery has been phenomenal. Battery life is constantly improving on Android phones, but it seems like every time something new is introduced it gets significantly worse. The 720p screen and LTE radio don't seem to be helping the battery cause. In the Nitro's defense, I haven't carried it an entire day to see how it works out for me. My Inspire could charge completely in about 2 hours, this phone will have changed less than 50%. But I have 20 Mbps download!!!

This is interesting since I don't kill apps, I don't use setcpu, and have only done minimal debloating. I do have pretty decent signal at my workplace (which is 4G, not LTE) which does make a big difference.

I wonder if it's the point? Maybe codeaurora just knows better how to undervolt SoC than setcpu does, just maybe? If Malnilion only tried to stop using setcpu could it made any difference?

Well, I'll be damned. setCPU was the problem. My battery life is lasting much longer now. With medium usage I'm at about 15 hours on a charge and have 7% left. If anybody is having a problem and is using setCPU, don't take my word for it, uninstall setCPU and see for yourself.

my experience has been the same using setcpu on my nitro. not sure if there was a sw conflict or if the stock sw simply does the job better but this phone runs much better without setcpu.
That being said, I am currently running JD ultimate and have its cpu gov running and it works much better imo.

How about charging your phones? My phone charges like 15% after an hour. Any tips to make it faster? Should I take it back to AT&T and get a replacement?

If you're using a USB port to charge that could be why it's so slow.
Edit: I am too, I'd say it's around 3 hours or so per full charge. Maybe slightly longer.

Good point. Now that you mention it, it does appear to charge faster when plugged into the wall. Well that kind of sucks. This thing takes forever to charge. I'll try with a wall adapter when I am home again and let you know what I find out.
It's kind of hard to always have a wall charger with me though.

It is not blackberry crazy short timing charges but I can charge it less than 2 hours from around 20% left using stock 1.5 amp wall charger. It definitely does not charge long.

Wall charger made a huge difference. Charged about 55% in an hour. Thanks for the tip.
Sent from my LG-P930 using xda premium

Am I correct to assume that the 2.1amp car charger would charge better/faster than the 1.5amp wall charger? I ask because with the wall charger I still consume power faster than the charger can keep up while watching SlingPlayer mobile.

Probably so, this phone is a battery draining beast. Every review I've read says LTE phones have terrible battery life. LG should have had an option to disable it and 3G. Oh well, I'll live with it while streaming on my 22 Mbps DL connection.
Sent from my LG-P930 using xda premium

That's just it though... I'm not on LTE while using SlingPlayer. I'm on 4G out in the field. My car charger doesn't say what it is, but I assume it's 1.5amp. I download "Advanced Task Killer" app, but everything I "kill" comes right back up. I think there's too much crap running and sucking down the battery. I really need to figure out how to root and freeze bloatware crap.

Same here. Battery life was a concern for me when I was first considering the phone. But I found that I can go a full day on a single charge. so I don't even worry about it anymore.

Why Do People Complain About Battery?

I've seen so many threads here and at The Verge that I just don't understand. I've been using Android devices now for about two years and I've NEVER had a problem with battery life being worse than my iPhones. I have a 3GS and the battery on it dies after about 8-10 hours of moderate use. Meanwhile, I'm at 12 hours on my SGS3 and 50% battery. I also have quite a lot of applications running in the background. Granted, today I have been low usage, but yesterday I was on the phone for hours and I still went 12 hours before the battery icon turned yellow. I haven't HAD to recharge before 12 hours for ages, even my Atrix went longer than that. I even have a screenshot from a few days ago where I went 14 hours and only dropped to 63%.
Are people just nuts or what is going on here?

People expect to play games at max brightness for hours and still get 12 hours battery life.
In with you, I use my phone constantly through out the day, I run my business from my phone, and routinely get 14+ hours per charge no problem. I just made a few tweaks, nothing big, and I'm good to go. This phone lasts noticeably longer than all my previous iPhones 3,3g and 4. Plus it charges twice as fast as those and never over heats... all my iPhones would get so hot that I couldn't charge them in the car with out testing then in an ac vent, and that's just from half an hour to an hour of talking... sgs3, I can talk for hours with no overheating, and it charges like a boss.

Before I flashed Cyanogenmod on my S3, I rarely reached over 10 hours of battery use with data on.

Neither one of my galaxy phones overheated to where they shut off until one decided it was dirty and jumped in the washer(rip 1st sgs2) .
I had changed my iPhone 4 back glass to one of those metal backs. Now when its on charge it will almost burn your hand if ur holding it. And I have had it shut off while on Facebook. Battery never last very long on I phones if the brightness is up data going WiFi seeking and jbing.

people complain even though they jumped from a 3.5 to a 4.8 720 screen device. Faster processor etc. With hspa or LTE speeds. I mean really. lol

My battery life is great! Much better than any other phone I've owned...12 hours of use for me is nothing....I get 18+ without a problem....frequently I've gone well over 24 hours.

Chargers. That is all.
I mean don't these people go home and charge your device?

I think some phones came with defective batteries. I'm running juice defender and could easily make it through a 16 hour day. 3-4 hours of screen time was not uncommon. 3 months later, and I can barely get 10 hours of use and 1.5 hours of screen time. Time to get a new battery!
Sent from my Transformer Prime TF201 using xda premium

I am not sure what is going on. I don't have the best battery life I can get 10 to 12 hours moderate use. Steaming music, reading rss feeds, checking email, 2 to 3 hours screen on. I would easily last a day on my iPhone 4. I have juice defender, lowest screen setting, custom kernel with under volting. I think it has something to do with my area. Att is so congested in my area I am barely able to use data sometimes. It's better with lte but still an issue at times.

People use their phones differently. Just saying.
If I don't turn the screen on, with LTE data, my phone dies in 9 hours (I tested it). And this doesn't mean there's a problem with it. I have around 15 different push notification apps running in the background, all of which are using data almost continuously. I don't think I can expect it to last much longer. And if I know I'm not going to be near a power source for longer than that, I simply turn off syncing to get better battery life.
To me, it looks like the LTE radio is the biggest battery hog. Let's see if the iPhone 5 can somehow get around this problem so that other manufacturers can take note

I was going to mention this. I noticed a significant improvement in battery life once I used JuiceDefender to turn off data while my screen is off. 4G LTE is the main culprit of most of the complaints for battery life (in addition to brightness). That is going to be a big problem for the new iphone if they can't get the battery management for 4G correct. It has taken Samsung a couple of years to get the battery working decent with 4G. I have my doubts that Apple could top them the first year running LTE on the iphone. Who knows, maybe that will be the "new" feature they have been working on over the year, LTE power management. That's the direction Motorola has headed in their new RAZOR MAXX devices. We'll see, either way, the consumer comes out on top as we have more competition to drive down prices and receive better products each year.

Best battery life for SGS3
With AMOLED and Android u gotta take special measures to get good battery life:
- kill bloatware. NostalgiaTurboSlim script will help. Or freeze unneeded apps - like Maps and enable them only when needed.
- disable various notifications - Play Market, WiFi etc
- disable ads - root and download AdAway app - they steal your mobile traffic, battery life and make you blind!
- put dark nonLive Wallpaper
- remove any widgets you don't use. I just removed all of them.
- disable animations and transitions
- disable haptic feedback
- disable touch tones/sounds/vibrations
- try using nonAuto brightness (I gave up on that - sunlight does not allow me to change anything manually)
- disable autorotation
- use dark Opera browser user.css
- use inverted or dark themed apps and Gapps, there is dark MMS, Twitter and Facebook in my ROM
- downclock CPU to 1GHz, or enable PowerSave On.
- use modern KToonsez kernel with PegasusQ governor, it downclocks CPU during screen off
- use CPU1 disabler script if your ROM/kernel supports it
- keep chargers around you, buy them at amazon
- buy spare OEM battery - I'm against aftermarket batteries, they are all fake rated
Or just buy latest iPhone 5 and enjoy.
Remember: Android is for tinkerers! That's why we love it! :victory:

Why do people still use some sort of battery management app life JuiceDefender or the like.
GET RID OF THEM NOW !(most of you that use it are probably coming over from an Iphone so you may be new but aren't well educated in how the Android OS works)
This phone comes with its own Task Manager as well as removing unwanted apps that are running in the background that you have previously used and don't need running.
So get rid of these dumb apps that don't do anything.

I believe this is the software bug that can be fixed in one of the threads around here. It deals with the Cell Standby that drains the battery.
Correct me if I'm wrong.

DISGUSTING battery life

Alright first of all, i want start off by saying that i LOVE this phone, both in terms of hardware and software, however, theres is a HUGE problem that i just can't get through and its the battery of this phone...
It is simply unbearable.
I have posted the screenshots. This screenshot is taken after 1 whole night of charging. In 5 hours or so time, I've use the music app for about 1 hour, talked on the phone for about 5-10min and sent about 10 text messages. I didn't do any web browsing/videos/gaming. I have also disabled LTE and turned my brightness to minimum with eco mode on. These small things drained my battery from 100% to less than 10% within 5 hours which i find to be completely unacceptable.
Last night, with me browsing the web on the bus for about an hour or so, it drained my battery from 85% to 3% by the time i got home...
I've looked at the battery life thread and it seems like im the only one experiencing this issue. Also not only does it drain SUPER fast, it takes a good 4 to 5 hours to recharge this thing. Which means it takes longer to charge than to use up even with minimal use...
Do I have a faulty phone and should I get it replaced???

Something's amiss. The only time that I've gotten less than 10 hours, is when I had my work email connection set up to "always connected" and wifi was turned on. Even then, I got 9+ hours of battery life.

Disabling lte is part of the problem. When the phone is in 3g, it uses fast dormancy which LG did not implement very well and it runs the CPU constantly. I encourage you to contact LG and your carrier and complain. don't let them tell you about background data or applications running the battery down. With the same apps running, this does not happen on lte. This can easily be verified by enabling debugging and then capturing a logcat from adb with lte both enabled and disabled. It will show fast dormancy trying to set network states every second. I spent a lot of time trying to get this issue recognized, but they kept saying that it had not been reported and was not a known issue. Let's make it a known issue so they will fix it.

How about actually showing us what you used instead of screen shots of %.... would be helpful...

Have you considered that maybe you have a faulty unit.

I'm also getting about 5ish hours on a charge. And, when I recharge at the office with the usb cord, it's a "trickle charge" that's so slow it's ridiculous.

you definitely want to return this thing.

Don't know about you...but I let my phone die twice then fully charged it but my battery life is amazing
Sent from my LG-E970 using xda app-developers app

Yeah, I've been quite impressed with my battery life on this thing. I made it from 6:30am spent about 2 hours tweaking it and setting it up, then messed around with it through the day. By supper time I plugged it in and it was at 63%.

I don't have the phone, but right off the bat i'd say it was whatever was causing your mediaserver to go nuts. Either some media app, YouTube, gallery etc, wouldn't say its a faulty unit, just mediaserver gone rogue
And damn i want this phone...

Looks like a widget or live wallpaper is going crazy

Well, a little update to this thread, i've disabled every different kind of syncing possible and i've been able to pretty much double my battery life from before, which is a lot better but i still wouldn't consider this to be good battery life.
I've been reading many posts regarding battery life, and it seems like there is some issue within the software that prevents the phone from going into deep sleep which is causing the lack luster battery life. This issue is on both the optimus g and the nexus 4, so i hope the devs may look into this issue when they are building custom roms for these two devices!

waaw Optimus G

I just got my optimus yesterday and had a full charge this morning. Been using it for almost 12 hours pretty steady. Have 16% battery left. I would say my battery is pretty amazing.

Get a replacement that's what I did with my first one. I was getting 6-7 hours with light use.
Got a replacements and was able to get 19_14 hours battery.
Also today I left my cell at home and it was unplugged at 100% after 9 hours I came home and saw it at 95%.

You definitely seem to have some weird issue's. My Optimus is great for battery life. My previous phone was an Xperia Arc and this has significantly better battery life without even running it in "eco mode". The only time I have noticed less then stellar battery life was when I had some app's running in the back ground that would keep refreshing/updating which kill's the battery.

Androids usage readings are inaccurate. Please consult this: http://forum.xda-developers.com/showthread.php?t=1179809
From what the picture shows I would guess its your 4G connection. A Hardware fault is improbable. And forget these things like "eco mode". Even if they underclock your cpu it won't give you a real benefit,

I've had great battery life on mine. Even when I've been geeking out on the device for several hours during the day.
Perhaps you are on the cusp of LTE coverage? If so, then the radio can kill your battery while looking for a signal.

I also have amazing battery life IMO, coming from a Galaxy S. I have no LTE in this area so am using only HSPA. Using the phone with casual use, I can easily go a full 24 hours on a charge. With very very heavy use I can go from 8 am till around 11 PM. I am very happy with the battery life overall. I'm running on "eco mode" FWIW.

[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.
