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?
Sent from my PC36100

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.

Nexus Overheating, Battery Draining

Hey guys, hopefully someone can help.
I have a Nexus with severe charging, overheating and battery drain issues. It's on stock jellybean, factory reset, no extra apps installed, and the battery will discharge in about 1 hour by just sitting idle. It takes maybe 2 days to actually charge to 80%. I'm about to replace the charging port to see if that will help.
However, it's also getting extremely hot. Not just mildly warm. And this is when it's just sitting there idle. Not only that, it's staying hot when the phone is off and not even charging. The only time it stops is when the battery fully discharges in about 2 hours... while the phone is still off.
Anyone experience this?
I have a grey market Galaxy Nexus which means I can't send it in for US repairs.

sounds like its time to replace the battery. is the battery leaking, discolored, warped, or "pregnant"?

Yes, I'm also saying it's the time for a battery replacement. They are fairly cheap, so you can fix it without spending too much money.

Nope, battery looks brand new, but I'll definitely order a new battery. Hopefully the ones on eBay are really OEM.

My battery gets to 122f while charging and wifi tether. I try to keep it near a fan and it helps some. But I don't have any battery drain issues. You probably just need a new battery.

New charging port, new battery and phone still charges extremely slow and drains real fast. About 20% in 40 minutes. Takes around 30 minutes to charge 2%.
Then when I take the battery out and put it back in, the phone thinks the battery is empty (I took it out with 30% charge left). Not sure what to do at this point since the only thing left to do is replace the mainboard which will probably cost more than it's worth.
Anyone have any other ideas?

Some screen shots
Sent from my Galaxy Nexus using xda app-developers app

After threatening to throw this phone in the ocean, it started working normally.
Trying to figure out what was wrong with it, opened it up again, put back in the old charging port (which had a higher revision number than the one I bought).
I waited 1.5 days for the phone to charge to 96%. Drained it to about 20% in less than 2hrs. Stuck it into the charger again but the battery was still draining. All the way down to 7% where it seemingly stayed stuck for a day. Then I guess it shut itself off.
Went to check on the phone randomly and saw on the power-off screen the battery had charged to 100% which never has happened and especially not in less than a day.
Turned it back on, started using it and battery drains sort of normally now. Overheating has also disappeared completely and now it also charges normally.
So in summary, I have no idea if this problem is going to resurface and I really didn't do anything to fix it. Though I would really like to know what happened to have it malfunction like this for almost a month.

[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.

[Q] Excessive battery drain while completely powered off

I'm having a very interesting issue with my HTC One. When I power the phone completely off (ie: Hold power button, click power off), the battery still drains when left alone for a few hours. I'd except maybe a percentage or two drained when the phone first boots back up, but its kinda unacceptable that in ~12 hours the battery goes down 15+%!!
Last night, at 8:00PM EST, I turned off my One with a bit over 80% battery remaining. I even rebooted into recovery this time and hit power off to ensure that the phone wasn't doing some crazy deep-sleep hibernation junk. This morning, at 9:00AM I turned the phone back on and had 63% battery! About a 20% drain for 13 hours of completely powered-off sitting on a desk? I've attached a screenshot to further describe the issue. I'm at a loss for this one. With my usage, the phone honestly drains the same amount of power with the phone off than if I just left it on!
To add more confusion: When I first got the phone (Monday after the launch), I didn't have this problem. I'd turn the phone off with 100% once it was charged and 12 hours later turn it back on to 100%. A week or two into using the phone, I started seeing this. I thought it was something weird with Stock, and Googling suggested that the HTC One had some deep-sleep hibernation mode to make boots faster, but after installing CM10.2 I have the same issue. Even with powering the phone off from recovery!
Any ideas? Anyone else noticing this? Is my One defective? (I hope I don't need to send it back.......)

You have to go into settings>power and uncheck fast boot. With this check it kinda puts the phone into hibernation mode and it never totally turns off.
My solution above is for a Sense based ROM not sure what may be causing this running a CM based ROM. Kernel maybe????

I did this while still on Stock; didn't change anything. Note that I'm now on CM10.2 where Fast Boot isn't a thing. Also, powering off from recovery should negate any hibernation, which I tried last night and still saw a 20% drain in 12 hours!

CLUELESS I don't get that kinda drain with my phone being on and untouched. It may be a defective battery.

That's what I'm thinking, although what is weird is that usually batteries are either defective on day 1, or degrade over time. It's weird that in the course of a week or two I went from a seemingly perfect battery (maintained charge while powered off) to a terrible battery.
To make matters weirder: I'd expect more than terrible battery life while the phone is on, although I'm not seeing anything excessively bad. This is going to be a nightmare trying to explain to VZ, especially because I can't just tell them I've diagnosed with CM10.2 and a custom recovery. What sucks the most is I'm (more than likely) going to get a "certified like-new" phone back... ugh...

Yeah, I feel your pain GOOD LUCK:fingers-crossed:

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
