As per the title really, what's the huge gap in my battery history?
I'm pretty sure it coincides with me going to bed and you can see where I woke up and started using it again but I can't imagine the phone was off entirely for several hours or more which this is indicating to me?
Anyone?
Damn, looks like you leave mobile data on all night? Try using aggressive mode on greenify and greenify apps you don't need whilst you sleep. Download better battery stats and have a look more in depth what's causing that huge drop.
I'm not talking about the drain, I'm talking in the gap in the history where nothing seems to be happening.

I had three of these gaps in my battery history last week, over the course of a number of days that the phone was on battery. Far as I know the phone was always on, so I wonder if it's just that there wasn't any recorded information in these gaps, or some other issue with how Battery History functions. I also noticed that the time since the full charge at the bottom left of the graph was longer than the Phone Idle time. Typically the Phone Idle time is similar to the time at the bottom left of the graph. Out of the two times, the time at the bottom of the graph seemed to be correct, while the Phone Idle time seemed to be considerably shorter than the last time I remembered charging the battery. I wonder if these gaps when the phone is on might just indicate that information wasn't recorded over a long enough time span, such as the idle time being too short, and it gets interpreted as the phone being off in the Battery History. I figure it's basically a bug with something related to how Battery History works.

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.
I have been noticing something strange. I have gotten in the habit of draining my battery down to single digits before charging in an attempt to keep my battery life up. I usually use netflix on 4g to do this as it does a pretty good job of sucking the juice down quickly.
A few times I have noticed that after I shutdown netflix and let the phone sit a little while that the percentage actually goes back up. For example, I kill netflix at 4% battery left. I set the phone down for a bit and when I pick it back up the battery is at 10%. I have seen this multiple times.
Just curious if anyone else has noticed this and anyone has an explanation for why this happens.
I believe it has to do with the battery meter displaying how much battery you have left based on what you are doing? So when you stopped being resource intensive it adjusted itself.
That's one explanation I have heard.. there is also one that has to do with the amount of current going to the battery.

I can't answer your question directly as there could be multiple reasons. (Battery capacity estimation is tricky business, and I don't know what algorithm they're using.)
But I can tell you that the common belief that one ought to discharge batteries before recharging them is not applicable to modern lithium batteries.
I was (to some extent) true for old-fashioned NiCd cells, but modern Li-ion cells shouldn't be excessively discharged. If you want to prolong battery life it's more important to keep the battery cool. (Lithium cells degrade much faster at elevated temperatures.)
(To contradict myself I have to add that the battery capacity calculation can be improved by discharging the battery completely from time to time - but again, this depends on the battery capacity calculation algorithm they're using.)
I understand the way current battery tech works. The discharge is not for the battery itself. Its for the Android OS. I have noticed that whenever I plug my phone in in the middle of the day, the next day my battery doesn't last as long. In fact the poor battery life will remain an issue for about a week until it levels itself back out. I have noticed this behavior on multiple phones by multiple manufacturers.
You end up going in a circle. You use heavy data one day and as a result you have to plug in in the middle of the day. The next day your battery doesn't last as long so you plug in again. Unless you allow your phone enough time to level back out then it will always appear that your battery life is aweful. Since i've been discharging my battery I am able to unplug my phone at 7:30 am, use it moderately all day with GPS, Bluetooth, 4G on/wifi off with a live wallpaper running. At 11:30pm when its time for bed I still have around 60-70% battery remaining. I find myself having to watch a few hours of netflix on 4g in order to drain the battery so I can plug it in.
I'm not sure if this behavior is a result of an issue with the battery stats file or what but I do know that when I flash a new ROM it appears my battery life is reset to how it was before I had shortened it by plugging in the middle of the day.
many of us have seen the percent rise slightly, its normal. when under heavy load watching videos or something and then you are finished, the voltage gets relaxed and pops up some. since this phone uses some type of voltage calculation to determine percent, it will jump up once in a rare while, typically right after you placed it under heavy load then went to idle.
it's normal..
Ive noticed this phone loves to turn on the display for any reason it can think of. That is not the bad part tho. The default lock screen can be swiped any where, and in my pocket this is bad. I did a test with my palm to simulate the my leg in my pocket. If the screen wakes up for any reason, SMS notification, easy to hit power button, Low battery notification (this one i don.t get) and you hold your palm on the screen and it detects it, it will hold the screen on indefinitely without unlocking it if it lands in the right place.
This is what i imagine going on in my pocket.

I have replied to texts, made phone calls, even turned the flash light on in my pocket and ran the battery down before lunch.
I use this "pattern security" so I'm not threatened by this "unwanted phone call making" and stuffs like that, but my battery life still seems to be poor. I noticed that if I leave the device on WiFi, then it drains about 30%/night (approx. 10 hours). But last night I tried turning off wifi and data--> only 2% of battery percentage went down during the same time (10 hours!!). !!
What do you think causes this strange battery draining through the internet(wifi or data?)? The syncing, or some specifig program, or just the fact that it's connected to the web? it's very strange.
edit: of course I checked the battery stats, but there everything seemed to be normal..

I really have no idea. I had this phone since release and it's always had mediocre battery life at best. This is my second Samsung android phone, The original Galaxy being the first and i wasn't to satisfied with that one either. I received a new phone yesterday (Experia TL) so the i927 has been sitting idle. Before i put it down i did a factory reset and pulled the sim. It lost 45% of the battery since yesterday morning. Any of my HTCs would last weeks in this state. So far the TL seems like it runs off magic pixie dust compared to the i927 lol.

My battery can go pretty quickly when I get the l2_hsic wakelock. Around 5%/hr while it idle (though I do leave wifi on). It appears randomly - some days not at all, some after a few hours of being on. The only solution I've found is to shut it off and pull the battery for a minute and hope it doesn't come back on the next boot. Searching didn't pull up much except its known on a few Samsung phones. Does BBS show anything under kernel wakelock for you?
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.

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.
I know this forum is rife with battery questions, but ironically it makes it harder for me to search for the answer to this..
I've had my 360 for a week or so now, and the battery's actually been much better than I expected.... until today. Today, for some reason, my watch JUST died at 4:30PM (I've been making it to 10PM with ~20% battery). id idn't do anything differently. When I saw it was at 6^ or whatever it was, I looked at the battery stats on Android Wear on my phone, and it showed the graph going from 100% to 0% pretty steadily throughout the day, but the statistics only account for like, 35% of the loss. Like, bluetooth was 8%, Android Wear was 6%, there were a few random things at 2% and 1%.... and it all added up to 35%. Where did the rest go? Is my battery in a funny state, and if so is there a way to "reset" it?
Thanks all.

Don't know about missing percentage, but I've noticed that about once a week my battery doesn't last the whole day. I've found that restarting the watch once a week helps.
