Is my phone the culprit? - EVO 4G Q&A, Help & Troubleshooting

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.

Battery Charging Issues

Normally I charge my phone nightly right before I go to bed and don't plug it in at all during the day usually.
I have noticed that on days where I have to use my phone heavily and require a charge midway through the day for the next week my phones battery life is almost cut in half. If I charge it regularly at night for a week or so the battery life will go back to normal. Has anyone else noticed this behavior? I'm trying to figure out if this is an incredible issue or an android issue.
Another thing I noticed is that under the battery stats it lists that my awake time is 43 hours. Its just slightly less that the up time. This makes me think that my phone isn't going to sleep. Anyone know how to tell if my phone is sleeping or tell me which app is keeping my phone from sleeping?
Install this app

Go to partial wake. in one of the drop downs.
I checked the partial wake usage and I don't see anything out of the ordinary.
I actually have an update to the situation. As a last resort I wiped my phone and loaded Cyanogen 6.1. At first it was working awesome. Battery life was awesome but as time went on the battery life got worse and worse and now i'm back where I started.
It sure seems like there is software problem with the way the phone tracks the battery usage/charging information. As I said it seems like charging the phone midway through the day or charging the phone before the phone is dead seems to have a negative effect on the battery. I don't get it. Letting the phone completely die isn't realistic. Charging the phone when I go to bed without affecting how long the phone last after the next charge should be totally doable you would think.
Does anyone have any suggestions or insight that might help me out.
You don't say if you charge with the phone powered off or on. But sound like you're always charging with the phone turned on.
I don't think the phone charges fully while turned on (to prevent overheating maybe? ).
If you can, I'd suggest trying to charge with the phone off, at least during the nightly charge.

Yes I do charge my phone while its powered on (like the rest of the world). I don't know anyone that turns their phone off to charge.
My phone is paid for by my company so that they can get ahold of me in the event of a server failure or some other IT related disaster. If the phone was off I wouldn't be able to receive those important calls.
I can't believe no one else has witnessed this type of activity with the incredible. I have tried 2 phones (replaced for an unrelated reason) and 3 batteries. The behavior seems like a software glitch. I have noticed with with both AOSP and Sense Roms.
Does anyone have an in depth understanding of how the battery system works on this phone. I also have an Iphone and the battery life compared to my android phone is ridiculous. I would use the Iphone exclusively but it doesn't do everything my android phone can do. I'm hoping there is a way to fix this.
Well, now you do know someone who charges with their phone off. Me!
I'm in IT as well and on call one week per month. But we don't run a third shift, so late night calls are almost never, and they have my land line number.
Back on topic, I have experienced better battery life while charging with the phone off. Maybe you can get an external charger until a solution is found.

Well i'm on call 24/7 and I don't have a landline.
What do you mean by "get an external charger until a solution is found." Do you mean a second charger to charge during the day? I have plenty of chargers. Thats part of the problem. Charging in the middle of the day I believe is causing the problem. Until a solution is found? Are you saying there is in fact a problem?
Having to leave my phone plugged in all day kind of defeats the purpose of having a wireless phone don't you think?
Please...anyone have any knowledge of how the charging system works in android and specifically how it might work differently on the incredible?

I should have said get an extra battery and a stand-alone charger that allows you to charge the extra battery while it's disconnected from the phone.
Have you read the thread in general titled 'your battery gauge is lying to you'. (or something like that). Good read. Also there's hundreds of other threads on the inc's battery issues. Well known problem.

If your up time and awake time are essentially the same, you definitely have something running in the background. Try menu/settings/applications/running services and see what program might be running that shouldn't be. You can also use an app called System Panel to do a comprehensive survey. I recently had an update that resulted in the program running continuously in the background, affecting my battery life.
Some other threads have discussed that after 40+ hours of up time, their phone goes into max CPU usage all the time. Again, using the app System Panel, I confirmed this for my own phone at 45 hours. My ROM is the stock Froyo 2.2 with a custom kernel. the simple solution is to power off/power on the phone which resets the uptime.
My routine is to charge the phone with power on over night so I can use the alarm. When I get up in the morning, I power off the phone and bump charge it for about 30 minutes until the light turns green again. Then I'm usually good for about 10 - 12 hours of uptime with 3-4 hours of awake time using a 1500 battery. That time can also be reduced considerably if I'm receiving a poor 3G signal.
I did originally have a problem with a program not allowing my phone to sleep but I have since uninstalled that program and now my wake time numbers are where they should be. I think the remaining battery issues are a result of me having to charge my phone in the middle of the day as a result of the misbehaving program prior to me uninstalling it.
It almost seems like the the battery in the incredible has a memory. On a hunch I have started completely discharging my phone completely everynight before I put it on the charger. As a result my battery life as almost doubled. When I get home at night I start playing angry birds with the brightness at full until the battery gets to about 3 percent left. This obviously isn't a permanent solution but It certainly sheds some light on the root of the problem.
Prior to doing the full discharge I did a bump charge and wiped my battery stats. The battery is working great now. I wish someone would create a kernal/rom that has this issue resolved. Since these new lithium batteries aren't supposed to have a memory anymore I'm thinking it has to be something that the OS is doing with the battery stats file.
According to this article you should fully charge and discharge once every 30 or so charging cycles to resync the battery meter with the actual battery voltage. So maybe the complete discharge fixed your problems.

not sure if this will help or not, but i have been running advanced task killer ever since 2.1(haven't gotten around to uninstalling before now, ha ha) and recently uninstalled it and installed watchdog task manager and my battery has increased two fold!
just my two cents worth.

Problem With Battery

Hey guys, I just got the droid incredible 2 and I first had the LG revolution but the 4g and the screen size made the battery drop down quick. I played with it for 20 minutes after it being fully charged, changing settings, and the battery went way down to about 80%. So I exchanged it for the HTC Incredible 2. They told me the batter was way better.
I went to the Verizon store to tell them the batter dowesn't last as long as expected. My Iphone 4 would be on all day, texting, pandora, email and web browsing and I still came home from work with battery left. My droid gets used from 7am to 1pm and its pretty much dead by then. They made me change the background data off, sync only email and weather, and download juice defender.
The batter still dies by 12:30pm after charging all night.
I have read all over people are getting excellent battery usage but I don't really know what to do to get the same. It is not temp rooted. Any ideas? Also, at work, in the building the data coverage is not so good so I usually do nothing but text on it and it still dies by 1pm.
I can't really say how well mine would do on the standard battery because I bought the extended battery immediately after getting the phone. I've been unplugged almost 15 hours and have 38% battery and I have sent/recieved 40-50 txts, 20 mins phone, browsed internet for 30-45 mins, played games around 30 mins, and listened to pandora for around 45 mins.
I would recommend the extended battery, it's $50 at verizon and I haven't even come close to killing it in a day.
Does the extended battery make the phone bigger? I'm thinking it would be thicker on the back. Would it have any drawbacks as to cases and stuff like that?
I'm not sure why mine is so bad, prolly because I am in a secure building and signal doesn't get through constantly. I'm surprised, I thought my iphone had bad battery.
the extended battery does have a thicker back. and yes, there are currently no cases for it, so there would be an issue there if having a case is very important.
as to your current battery, if your in a biulding with bad signal, that will most defintiely affect your battery life as your phone will have to use more battery to try to find a good signal. additionally though, the phone battery does seem to improve after about a week of charge/discharge cycles. not sure why this is, but i have seen it on my phone and seen many other report the same.
The battery sticks out a little more than 1/8th of an inch I would say. However, IMHO it protects the camera lens and flash lens from getting broken and I never really like using a case anyways.
I have amazing battery i charge it to 100 percent unplugged after then go to school texting 100-200 average everyday internet music by the time i get 3:00 i still have 80-70% and i'm 13 so imagine how much i use it and it still stays at that percentage
Having a phone in a building (or anywhere) the signal is weak is a drain on your battery. If your iPhone was with AT&T the signal may have been stronger where you work than with Verizon and may have therefore contributed to better battery life.
Also, if you didn't FULLY charge your DInc2 and FULLY discharge it right when you got it, you should really do a factory reset and immediately do the following:
Charge the phone for at least 8hrs with the power off, unplug for a few minutes, plug it back in. The light should only remain red for 10-20 seconds before turning green, otherwise this unplug-plug part should be repeated a few more times always letting it remain on "green" for an hour before unplugging an plugging back in.
THEN power up and use the phone until it shuts itself off because the battery is drained. Let it sit for a few minutes, and turn it on again. It should sut itself off again pretty quick. Let it sit, turn on again. Do this until it wont power up at all after sitting untouched for a few minutes and your battery is then fully discharged.
Now you can plug it in and start the charge part of the cycle as lined out earlier. Once the light turns green 10-20 sec after plugging it in again you have completed one "cycle".
This may sound excessive, but I'm kind of a nut about this kind of thing.
I didn't do anything special when I got my I2, am a realtively heavy user, and have an all day battery life. I'm pretty careless with my features being left on.
If you can't get it to last all day, either you are a much heavier user than I am or you do, in fact, either have a battery problem, or a battery calibration problem. You shouldn't need to calibrate the battery algorithms, but I guess it doesn't hurt to try.
I wouldn't say I am a heavy user. I normally text while I am at work and check facebook a few times. I also listen to pandora most times. I work for Vanguard and most people here have Verizon I believe. I was told when I switched from AT&T that signal should not be a problem where I am at. My Iphone 4 would get used much more and it too would have signal problems as well until I turned 3g off but it would last way longer than the droid.
I guess I can try the factory reset and full charge cycle this weekend but I'm not sure what Verizon can do for me either so it may just stay like this
this is bump charging no? (well the part about how to charge it). i spoke to am htc rep that said that bump charging will significantly decrease the lifespan of your battery life and therefore is highly not recommended.

I just got mine on Sunday, but even yesterday I was texting and surfing a fair amount yesterday and went to bed with the phone at 61%...
I am sort of amazed, I think Verizon has taken the underclocking thing and put it to work on the official release... at one point I turned off the screen for what amounted to an hour and when i turned it back on it was still the same battery level.

if your comparing battery life on the dinc2 with 3G on versus the iphone with 3G off there will also be a pretty big difference. if your tuirn off 3G on your dinc2, i would imagine battery life will be similar or better than your iphone had with 3G off also.

No I was comparing the Inc 2 to the Iphone with 3G on. My iphone would also last longer if I turned 3g off and just used Edge or whatever it is called. I don't think I can do this with the droid until it is rooted or download an app to do this.
I turned off juice defender and we will see how it goes today. I don't really like apps running in the background and it was turning off data eacht ime the screen locked.
I think the biggest difference is the verizon signal. The battery on this phone is amazing for an android device. While it is still nowhere near iphone 4 status as far as battery, it shouldn't drain like that. Have them either swap you a battery or the phone itself.
I'm a relatively heavy user. Especially with voice calls and I can go a day and a half easy.
But I also run launched pro with only a couple of widgets. To me sense is a battery hog.

What would I do to go about swapping out the battery or the phone itself? Should I go back to the same verizon store? Or call them on the support line and try to get a battery or new phone that way? I have no clue why it is draining like that either, the signal can't be that bad, I literally had the same signal with AT&T in these buildings.
Well, lets be honest, one of the things Apple really puts a lot of time and effort into in their development is long battery life. It wouldn't surprise me to see the iphone outlasting most Android devices.
In any case...
While I don't need to, I do charge my phone while at the office. If you have a desk job then I don't see how this would be problematic. My work day usage includes 2 hours of bluetooth streaming (in my car to the stereo), media playback (music/podcast), and mapping with gps and 3g data (this drains my battery pretty quickly, but that's relative...it's about 15% per hour). Outside of that, my battery drain is quite low.
I only started charging at the office because I like to keep my battery as full as possible in case of extended emergency that requires being away from a charging source. It's that whole boy scout be prepared mentality I have. Besides, if you have the opportunity to charge, why not? It seems to charge pretty quick anyway.
I can charge at the office, but normally I forget the cord at home. Not a problem to buy another one but still. I was just concerned because I hear people getting 15 some hours on one charge and as of right now, my battery is below 50% since I just got back from lunch.

take it back to the store, and if that doesn't work then call. but the store would probably be a better bet as they can give you a new phone or new battery there whereas the phone support, you'd have to wait for the shipment.
Seems as if they were not able to help in store the first time. Rather than have someone check it out, they had someone come over and tell me I should turn off all the sync and data features. So I did do that, but then why did I get a smartphone?
It's possible you have an app that is not allowing the device to sleep. If it can't sleep, it will drain the battery much faster. You might get 8 to 12 hours awake yet idle.
Are you using many third party apps? If so, have you considered going through them, removing them one at a time, until you find the battery doesn't drain so fast anymore?
If you go to About phone in settings, then Battery, the last item will show awake time. This should be much lower than your Up time.

[Q] Battery % increase with reboot?

Last night my phone was down to like 5% so I plugged it into the charger and kept using it. It was plugged in for maybe 10 minutes when I got another bettery warning that my device was at 14% (the plug had come out). Since I was almost done, I decided to leave it unplugged since the plug gets in the way anyway. Shortly thereafter, I think the Volume+ app caused my phone to crash. It just turned off. When I turned it back on, my battery was reporting 39%! I wondered if it was a fluke, so to test, I switched to 4G from WiFi on, listened to music, and continued to use my device to see if I did indeed have more time with it. It went for another 40 minutes or so before the battery was back down to 5% and I plugged it back in and went to bed.
What gives? I feel like my battery life is exceptionally awful, but I thought I was experiencing the Android OS awake thing, since my awake times do seem to be pretty high, like 50% of my time on battery even though the screen is probably on for less than 25% of my time on battery and I only have google apps set to sync in the background. Last night's mysterious battery increase now leads me to think differently though.
Are my battery stats out of whack? I'm not rooted yet so I can't reset them that I know of. I am planning to tackle it this weekend, though. I was waiting to make sure the phone doesn't have any issues so I didn't have to go through relocking it to return it.
Attempting to attach a screen shot.
Normal Android behavior. I've seen it on every device I've had since the G1
The battery and the OS become mismatched if you restart while charging. The OS will report a "faster drain" when it reality itsvjust trying to match back up with the battery.

my 1st GSIII was defective(phone HOT while off)

Just an FYI,
My 1st sprint GSIII was fine for the 1st month. I could get upto 3 1/2 days of battery with very light usage (mostly standby time). NOt sure what caused what happened next but the phone became extremely warm and the battery life dropped to approx. 2 hours. The phone was very warm even while off for hours!! And it obviously got even hotter while on the charger. The only way to get the phone to return to room temp was to pull the battery and leave it out for a few hours. Turning wifi/data/sync/GPS etc. off did nothing. The odd thing was, the battery was a normal temp. The heat came from the lower part of the phone (where the processor is). It also gave incorrect battery readings. While plugged in it would read "100%" and "charging" the LED stayed red, never turning green. I also could pull the battery and put it right back in and it would read 20-30 % difference VS. when I took it out.
The phone was swapped at a sprint store covered by insurance.
The only thing i did differently usage wise was link the phone to my dropbox account. It seemed to sync normally so i can't confirm dropbox caused the issue. I just can't figure out what the phone was "doing" while it was off. Just thought i'd share the story with the phone. The new 1 is running fine.
I found this today. Appears to be helpful with heating up and improved battery life.

This doesn't sound good at all. My cousin's GII on AT&T did something similar to this. The phone would be completely turned off and it would vibrate every 10 minutes. Even pulling out the battery and reinstering it made it automatically turn back on and vibrate again and again.
Hopefully this is an isolated issue what you are talking about.

What kind of signal are you getting?
Mine was like what you descrbed for a couple days(almost no signal at home) and I was getting ready to return it but didnt have time because I was leaving for Vegas. Long story short when I got to Vegas I upated profile and PRL and havent had a problem since. Maybe the towers in your area are under constrction.

My phone has gotten hot ever since I got it, but it will cool down when I stop using it. I am getting horrible battery life even witha 4300 mah battery. today it wouldnt even last 11 hours. It had 3 hours total usage time on it. I am now trying another 4300 mah battery to see if that is the problem or if its the phone. my reg battery wont last me very long either. I am also using juice defender free version and advanced task killer plus the built in task killer and I cannot get my phone to last very long. With my orig Evo I had the sprint extended battery (2500? mah) and it last me til bedtime with 50% left.
The only time this happened to me was when an badly behaving app "ran away". I would get really bad battery usage at the same time. I could cure it by clearing ram, which shut down all the running apps. Since this hasn't happened to me in a while I'm guessing that whatever app was doing that to my phone has been updated to fix the bug.
My issue was very odd. My phone was normal lasting up to 3 days with very light usage. It would sit for hours at "room temp"..the only thing i did differently was link it to my dropbox accnt. It seemed to sync ok..it was shortly after that i noticed the phone was very warm towards the lower 1/3 of the phone. I thought maybe there was something running or taxing the processor. So after working on it for a few days(turning everything off i.e. wifi/gps/data/sync/etc etc.) the battery got worse and worse. I then unlinked dropbox, stopped all running apps and let the phone sit in airplane mode over night. Still no joy. So i turned the phone off and let it sit for about 6 hours. It was still "very warm" while off!! At that point I pulled the battery for about 2 hours and the phone returned to normal temp. What could the phone be doing while turned off for hours?
The phone was stock and updated. I use an airrave so i dont have signal issues. The processor seemed to be running at full load even while the phone was off. The battery life went from around 3 days to not even 2 hours. The phone did seem to have the known "cell standby" issue(where the counter is reporting an incorrect usage %). While charging, the phone was even hotter to the point of me thinking it would burst. Oddly enough, the battery was at a normal temp. It was no where near the temp of the bottom of the phone(where the processor is located).The new GS3 is running normally so far. The tech at the sprint store couldnt figure the old 1 out so they just replaced it(insurance/no charge).

Annoying Battery Issue

My Note 4 is 14mo old and for the last couple months it just shuts off on me even though I have plenty of power left.
I am a light user and usually have enough power for all day use. I rarely use my phone down past 10-15%. I always put my phone on the charger when I go to bed at night when I have somewhere around 20% charge left. If I notice that I might not have enough power to get me through the day I'll put it on the charger somewhere between 30 and 40%.
Lately, like tonight I got a low battery warning at 30% power while I was on the phone. Not even two minutes later it shuts off. When I turn it back on it starts to boot up but then shuts off again. When I put it on the charger it was completely dead. This only happens 3 or 4 times a month but it's annoying because often it happens at the most inconvenient time.
I've also had it shut off and then when I put it on the charger it starts charging at 28% power.
Please let me know what may be going on here and a solution...
Thanks...

I've also had it shut off and then when I put it on the charger it starts charging at 28% power.
Please let me know what may be going on here and a solution...
Thanks...

I had the exact same issue. I had 2 different batteries shutting off at 20-30%!.... Replacing the battery to a brand new one simply fixed it!.... if you are going to order one online try to avoid unknown brands . Also, pay attention there are some fake Samsung batteries claiming to be authentic.
Also if you still have warranty, contact Samsung and they should send you a new one. That's what i also did.
So you think its the battery and not software related? I was thinking software issue because I don't abuse my battery by running it dead and it's an intermittent problem.
I know that the life cycle of Li-ion is greatly reduced by repeated draining to below 10% (my kid's phones suffer from that. Seems like they can't make a battery last more than 6mo) but I've never had a phone battery go bad on any of MY phones including my old Note 2 even after two years. Maybe I just have a bad battery?

Doesn't matter whether you abuse the battery or not. Some batteries just go bad faster than others. I also think it's your battery.
A factory reset without restoring apps will rule out a software issue though, but since we can't root, it likely isn't anything messing with your battery percent unless it's just an app draining your battery. But even if it were the latter, your battery wouldn't die then start charging at 28%.

Pretty sure this is an actual built in feature. Mines always died at ~20% (since the 5.1.1 update) and once plugged into a charger and rebooted all my running apps and clipboard info is still running as if the phone never died.
My battery is brand new (from warranty replacement) and it still does this so this is why I think it's a "feature" to keep you from losing data in the event of a low battery event. Just my opinion.
It's not a feature. Mine goes all the way to 0% before it dies. I once read to take out the battery, hold the power button for 30 seconds (while the battery is out), then put it back in and see if it helps. This supposedly gets rid of any residual power storage. I don't know if this is a placebo affect by after I did that, my battery now goes all the way to 0 before dieing.

Not exactly a placebo, but not sure if it truly helps. Doing this would clear all electricity stored in any capacitors in the phone. I'm just not sure how this helps.
And my battery goes all the way down to 0% too. It's not normal for the phone to due at any other % (except maybe 1%).
