Is my phone the culprit?

So like everyone else my battery life sucks. No big deal. I bought the extended battery from Sprint, and I can see the battery diminish in front of my eyes. I mean dropping 1 percent per minute. Is there a way to test the phone to see if it is the culprit?

ther are lots of ways to check things. does it drop 1% a minute all the time meaning you only get 100 minutes? does it only do it when you take it off the charger at 100% where ti will drop to any where from 99-90% in a matter of minutes?
if the later then thats normal and is because the phone doesnt have a trickle charge. this means that the phone charges your battery to 100% then stops however the indicator on the phone will not change it will still show 100% once the acctual power reaches 90% the phone then charges again up to 100%. what this means is once you take your phone off the pwoer if it has been sitting there even if it says it is at 1005 it can be any where from 90-100% which the battery quickly changes to over first few minutes.
If it happens past 90% and all the time then something is wrong and you likely have at least 1 if not more apps running wild on you, you have things set to sync constantly, and you have everything under the sun turned on for your phone.
for apps the paid version of system panel is very nice for monitoring you can go to monitor top and top apps and see which apps are using the most battery/cpu.
witht he information you have given that is aobut the best i can tell you. I would not say everyone has crappy battery life with the evo as i have slowly gotten my phone set up and now with moderate usage i can get 14-15 hours and at least 8-10 with very heavy usage(stock battery) which i dont consider to be crappy battery life.

I appreciate the response, and I forgot to add that I'm running stock unrooted sense. This is not my first Android phone so I know about battery managing. I don't have everything sync every two minutes nor do I have everything turned on. It does drop rather quick even past 90 percent. I think it might be the phone it self. I doubt I got 2 bad batteries, one being extended. I'll see if I could get a device swapped out.

My first EVO was like that. It drained quickly shortly after charging. I could never figure it out. Till one night before going to bed, I noticed something weird about the bottom keys on the phone. They were " very dimmly " lit. The home, menu, return, search were all dimmly lit. It was I believe a defect in the phone. I got it swapped out. No problems like the 1% drain since then.

Battery?

Can someone explain this? before I went to bed my arc was at 97% battery when I woke up it was 100%?

Cellphone battery meters are not that accurate. That is why on "stock", the manufacturers do not put numbers, just icons. No one has "invented" an accurate meter yet that shows exact percentage left. So don't worry about it too much.

If I am correct your percentage is also calculated by the use of your phone, so kind of like when moving a big file in windows, at the start it says two weeks and after a minuut it says 5 min remaining cause the cpu is less stressed

ive also encountered this kind of issue before because i always look at my battery widget. before i use it i look at the battery it was 30+% and then after playing it came back to 42% it was weird..

Erratic battery readings

Anyone experience this before? Lots of spikes and falls throughout the day. Look at my battery graph, it almost seems to be charging itself at times (especially around the 30% mark). I notice it goes up when the phone is in deep sleep, but when I use the phone, even with light use (texting), the battery drops quickly. About 1% every few mins. Then the battery starts going back up again once it idles. However, I'm still getting decent screen-on time, so i'm guessing its just the way my phone is reading the battery levels?? I'm certain its not an ICS issue either, as I saw this happen on GB a few times. This comes and goes with any warning and I can't seem to replicate it on demand to figure out the issue.
I'm going to try this calibration method and see if it helps: http://forum.xda-developers.com/showthread.php?t=1312273

[Q] battery life suddenly horrendous

My battery life suddenly became horrible this morning. Normally I unplug my phone every morning around 6AM, and i dont need to charge it again until closer to 9PM.
This morning, I realized that despite being on a full charge at 6AM as usual, my battery was completely depleted by 10. I checked the battery "app" and it said that phone idle and cell standby were both at 13% usage, and that was the most i had used my phone. it registered the full time (4 hours) of usage for those 2 but it also said that it was only responsible for 13 % of my battery drain each. After that there was google play services.
I figured it was just a fluke, so I reboot the phone and recharged it. Once again, the battery drained in a mere 4 hours. This time it told me a voice call of only 10 minutes length was responsible for 35% of my battery drain, and that having my screen on for a seperate 10 minutes was responsible for 25% of my battery drain. This might be fine and dandy if the actual draining chart showed a steep fall off when i made the call, but that is not the case. the chart is a straight line showing constant drainage with no steep or flat areas. I'm thinking something is definitely wrong and the phone is causing itself to drain. maybe something hardware oriented, since i dont even have very many apps downloaded.
I've literally only interacted with my phone maybe 3 times today, and I didnt even do anything major.
Do you guys have any ideas as to what is going on with it?
I'm CM10, latest stable. not the monthlies. no cpu hacks or anything, and as I said, this problem cropped up this morning. before this everything has been fine.

Please search for Better Battery Stats here on XDA. That thread has quiet a few tips on saving battery drain.

If I hadnt already made sure I was following the tips and I wasnt dead sure that something was the problem, I would not have made this post.
I did manage to figure out the problem by sheer dumb luck and a little bit of educated guessing.
I uninstalled the MyFitnessPal and tried again today. I'm exhibiting normal battery drain now (10 hours and im at 46% with not too much usage of the phone).
If you read the post I made, no apps were showing up as a large battery drainer, and all my stats were reporting incorrect times (13% battery usage for a 4 hour period despite showing me i only used the phone for 10 minutes). So something was definitely wrong. Uninstalling the app fixed the issue though, so for anyone who exhibits this problem, uninstall whatever apps you most recently installed and do a reboot.
I didnt have to reset or anything.

2% drop at time on battery gauge

Guys what the hell, why this phone and Nexus 6p drops 2% of battery pratically every time? Some users says that the fault is of Doze, and some says that is bad battery. Just answer three things
[Question 1]
This problem is a software based or hardware? And if is software, there's some how make it stop doing this? It's annoying and makes me sick with the time of usage .
[Question 2]
Why in the hell some users have this issue and some not? That's a russian roullete? Really I'm mad.
[Question 3]
Are you getting this problem? Already solved this? Suffer yet with and doesn't even know how to troubleshoot this?
GRR really. I'm mad. And seems that happens on the same percentages, 99% to 97% 95% to 93% 90% to 88% and there it go...
note: When the phone is under 60% to 100% it stay in a temperature of 35º, and you feel your phone a little hot, but when it arrives at the 50% ~ 60% down, it seems to be a little less hot, is that the processor's core being shutten down in order to give priority to the battery?
REALLY I can't understand the behavior of this phone. It's really strange, and how I never had one, I have no parameters to make any comparison.

It doesn't seem to be set at certain percentages but rather starts at where the battery is when you go there and then goes down by 2% at a time. I've never sat around and watched it before and it certainly doesn't irritate me. I have a one percent battery on my statusbar I can watch if I need something more accurate.
