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.

[Q] im still having problems with my extended battery

I don't understand why its not working correctly I did everything I was my phone isn't rooting is there anything else I can do to get it to work correctly without rooting it???

I'm obviously missing something here and your post isn't very clear. Why would you need to root your device just to use an extended battery? That doesn't make any sense. All you should have to do is put the extended battery on a charger and charge it until it is full and then for a few hours more initially, unless the directions state otherwise. Afterwards, insert it in the back of your EVO, turn on your device and voila! If your device isn't functioning after doing that, assume you have a defective extended battery and return it to where you got it from.

Your gonna have to go through like 5-6 FULL/discharge sessions. Charge it for like 3 hours after it hits 100% and then disconnect it and dont charge it UNTIL it completely dies. Then do it again like 5 times.

Everyone keep saying I should root my phone for it to work correctly

Thats so you can install a SBC Kernel but forget about that. Just do the full charge/discharge cycles and your battery should be good in like 3 days.

Iight Imma do it that way now

Even HTC said do NO fully discharge your batery, so I'll take anyone that poists that as bad information.
Here's what works for me:
Here's what I do, and I get PHENOMINAL Battery life.
There are two ways of conditioning a battery that stand out above the rest, and I combine them.
Download the battery monitor widget/app
Set it to your battery's maH in settings.
This isn't totally a needed step, but is a useful app.
Charge your phone until full.
Unplug it, turn it off, then plug it in for one hour.
Turn it on for two minutes, so it fully boots.
Turn it off, unplug it, when the light goes off, plug it back in for one hour.
That part of this is actually from HTC, on how they found the best results for charging.
Now, before you plug it in, unplug, wait for the light to go off, plug it back in.
When the light turns green, unplug it again. Repeat that step 10 times.
(It may not take 10, it may take more, but 10 is good)
While plugged in, boot to recovery, wipe your battery stats.
Then reboot to system.
A good habit to preserve battery life is to keep mobile data off, unless you need it. I used to turn wifi off, too, but lately, I leave it on.
How good is this?? I take my phone off the charger when I leave for work at 7AM, and usually, I go to bed at 11PM, when I charge it back in, and it's never below 80%, unless I've been really using the phone excessivley.
The other thing is, I do this, somewhat daily. I wake up, tuen the phone off ,so my alarm doesn't keep ringing every 15 minutes, unplug it, then not turn it back on til just before I leave, so it's getting that "treatment" at some level, every day.

ok but how do i wipe my battery status?

You have to be rooted to wipe your battery stats. Just do what i said byt dont let the phone fully die then. Let it get to like 5% or something then FULLY charge it for like 2 hours after it hits 100%. Do that like 5 times. What the other dude said will work too. Just do what your comfortable with.

yeah im doing it ur way now

[Q] Inc consumes battery when turned off

tldr: My Incredible drains battery when turned off :-/
I have an HTC Droid Incredible that I use for testing my developed apps, and for playing around with people's roms, and I have found an odd issue with it. I can charge up the battery and use it for hours and hours and it consumes what I would consider a normal amount of charge, but when I turn it off, it still consumes battery charge. I'll charge it to 100% and disconnect the charger, hold the power button and select Power Off, and when I turn it on the next day the battery is very depleted. Yesterday I did this, and this morning about 16 hours later, I turned it on to see a 23% charge. If I leave it for more than a couple days, it won't even turn on at all and I have to charge it again before I can do anything with it.
I've tested this over the past few weeks with two separate batteries (one used, one brand new), and the same thing happens with each battery. It's definitely the phone and not the battery, because I have taken the batteries out completely, waited a few days, and they stay near 100% charge.
Some history on this phone:
I got this phone from a friend in a semi-working state. I couldn't root, s-off, or really do anything with it, so I did a factory reset, messed with it for a while, and finally decided to follow the steps in this thread to "unlock,downgrade,and achieve s-off with htcDev". This has allowed me to mess with roms, etc, so I have installed a couple, and now have "inc-eng 4.1.1 RC2" installed from this thread, and this kernel: "[email protected] #64 Mon Sep 3 18:55:57 EDT 2012"
The issue at hand however was happening before I even had it in my hands, as my friend described the same thing happening to him (he did not mess with rooting, roms, etc).

Maybe the battery is bad... take it out of the phone at 100 and leave it overnight and see what happens life wise

Thanks, but I did test that, with both of the batteries I have. I've left them for multiple days out of the phone, and when put back in they show 95-100%.

Maybe it's not turning off all the way.
Here's another test: turn it off, remove the battery for about a minute, then put the battery back in. Turn it on the next day and look at the battery level.
Might be a ROM issue. What ROMs have you tried this with? Have you tried stock sense and CM7?

Will do, I'll post tomorrow with my results.

If you have fastboot enabled then the phone is never really off. Try charging it then pull the battery, and put it back in the phone but leave it off. Turn it on latter and see if there was any battery loss. Fastboot is like hibernation. Its possible that some app is misbehaving and trying to sync or something while its hibernating, draining the battery.

Alrighty so yesterday I charged both batteries to 100%.
Battery A stayed out of the phone on my desk.
Battery B I removed from the phone, waited 10 seconds, and put back in the phone (I did not turn it on).
This morning, the phone (with Battery B in it) would not turn on until I charged it for a few minutes, and displayed 0% charge when it finally let me turn it on with the charger connected.
This is so weird...
Also, the rom I'm using doesn't have a fastboot option that I can find.

Okay so Battery A I put into the phone at 4pm yesterday, turned it on and found it had a 73% charge. I then turned the phone off, waited a few minutes, put the battery in and left it on my desk. This morning 12 hours later, I turned it on and it has a 25% charge.
I'm so confused... if I don't turn the phone on, how are the batteries discharging? Both batteries keep their charge when left out of the phone for a prolonged period, but discharge when in a phone that hasn't been turned on. Bah! >_<

Mabey there is a short in your phone somewhere. Does the battery last like normal when the phone is on, or does it also die quickly?

I'll have to test this when i get home, but I beleieve the battery discharges at a normal rate when the phone is on.
(this is not my normal phone, just one I use for testing apps, etc. so I don't use it on a regular basis)
I'll charge one of the batteries to 100% and leave it on overnight, and post my results.

Okay I left my phone on for 18 hours in airplane mode, and it drained battery SLOWER than with the battery inserted into the phone and the phone never turned on.
So weird... I don't understand.

Mine drains when all the way off 2 but not that bad... I think it may be the MotherBoard keeping power to the Nand memory so it dosen't relock and keeping power to the CPU so it can be quicker on bootup

I'm assuming there's no way to stop it from doing this?
It's not a huge deal, as this is a test phone I use for development, but I may be eventually selling my test phones, so I try to keep them in good working order, or get them to a decent refurbished point Plus this is a weird enough phenomenon that I figured it deserved discussion.

There maybe no stopping it I guess because mine does it 2 but not that fast..... Oh yeah an I think this is the 1 test phone you don't sell It has 2 many good devs

Phone was 25% battery, But 50% battery after reboot?

Hey guys, I've had my phone for 4 or so months now and I always charge it while my phone is off and never had any charging/battery issues until today, I decided to charge my phone while it's on and it charged up to 25% and I restarted my phone without removing it from the charger and after it booted back it it's showing 50%, I restarted a few times, tried a cold boot, it's still 50%.
Is this a known issue with this phone? does anyone know what's causing this? I've never had this happen before.
EDIT: After this happened I ran my battery to 0% so I can attempt a battery calibration and when I poped it on the charger it showed my battery was actually 0% and showed a yellow hazard triangle thing (normally it only drops to 1% and there has never been a yellow triangle before)

Sometimes the Android system can incorrectly report a battery charged. I have had it happen to me on my Nexus by about 10%, but have not had it happen to me on my G3. I would not worry about it too much if it only happened to you once. If in continues you to jump around in battery percentage, then I would suggest getting a replacement battery. Keep in mind to try not to leave it charging for very long after reaching 100%, from my experience it can effect a battery's ability to hold a charge if that is done repeatedly. Which means do not leave it charging overnight while you are sleeping. Also I would not suggest running it until 0%, I would imagine a sudden shut down of the Android Operating system is not a healthy thing for it either. Just like it is not good to go up to a computer and just pull the power cord.

Thanks for the input.
I never leave my phone on the charger while I sleep since it only drops 1% while I sleep. My phone actually only goes on the charger like 3 times a month
I know it's not good to fully drain the battery very much, I was just draining it to attempt a battery calibration in the os. And when I do this my phone usually only drops to 1% then dies, but all of a sudden it dropped to 0% this time and showed a big yellow triangle with a big exclamation mark in it
Anyways I reflashed my rom in hopes I can flush the problem out. In 4 months of owning this phone I've never seen this warning before.

This is almost exactly what happened with my old phone (Samsung Captivate Glide). If this continues to happen, it is one of the first signs of the battery failing. But if this is a one time thing, I wouldn't worry about it.
In my case, the battery was going bad. It started going from any % battery, down to 0 instantly, forcing a shutdown. After rebooting, It would show a decent charge (~60% most of the time), but would do the same thing within 5 minutes. At first it only acted up like this once a month, but it became more and more frequent that it happened every day, after using the phone for only 15 minutes. The only fix is to get a replacement battery.

tyvm, This is extremely helpful info to keep in mind. Now that you mention it I have seen the battery kinda swollen up a couple times when it got hot, only ever so slightly but I did notice it.
If my issue persists i'll defnitly try a new battery, thanks for the tip

Pixel 2 XL stuck at 30%

Hey guys. A problem just came up on my phone. I plugged the charger in and it went from 25 to 35 % in like seconds, I unplugged, plugged again, restarted the phone, factory reset everything. It won't charge past 35 %. Now after I have unplugged, it went down to 30% and it's stuck there for about 2 hours... Neverending battery

Very strange. And did you try using it at 35% and see how it lasted? I was thinking it's not getting the proper percentage reading but was really at 100%. So it possibly would stay at 35% for hours. Either way, it's still something wrong and go for a replacement.

Not that easy, I bought it from another country, getting a replacement would take a long time and the phone btw came back. Tried to charge again yesterday and no problems, charged 100%. Battery otherwise runs normal, about 5 6 hours of screen. Just this issues where it doesn't read the percentage sometimes

You might want to try one of those "battery reset" apps on play store -- something about a file not working or syncing right and maxes out at a lower percentage. The app usually has you hit 100% as best you can guess, then they delete and replace the system file which automatically starts at 100%...
The main problem I foresee is if you are using Pie because I have my doubts Pie may measure battery fullness in the same way most of those apps have it set...
good luck and hope this helps...
