[Q] Sleep of Death with Stock - Samsung Epic 4G Touch

So I read about other people having this problem with custom ROMs or rooted phones but I am on unrooted stock after OTA. I thought was one of the 60 or whatever apps I bought during the 10 cent promotion but I uninstalled them all and I still had the problem. It's not frequent but it's happened 3 times in the last couple of weeks. It's mildly annoying to have to pull the battery but the part that I can't live with is that whenever it this happens, my battery drains like crazy. The battery usage drops off a cliff and I caught this one after no more than 5 minutes. Any thoughts on this? I don't have an SD card so it's not that. Thanks!

to find the rogue app use betterbatterystats and cpu spy. not sure if they superuser. also badass battery works too.

Mine did this the other night on Calk's ROM. Something got stuck keeping the phone awake causing that cliff like drop off.

Happened to me on stock once, installed some game but didn't play it so I don't think that was the reason. It was either the default browser or the contact list.

Thanks for the replies. I figured it was an app but wanted to be sure before I started deleting things. I was just worried that this might be something to do with hardware or something.

I have same problem with different roms and i don't know what to do...

I had the same problem I figured out it was my wifi being turned on all the time. I have always heard leaving your wifi on when it's availible was supposed to save battery but I checked in better battery stats and saw there was almost 7000 wakelocks in a 5 hour period. I turned wifi off problem solved I only turn it on when I need to.

It is happend even wifi is off.

Your battery might be going bad... take it out and spin it on a flat surface if it spins freely the battery is most likely done.

My battery have 3 months old. My s2 is new....

Same thing is happening to my friend's white E4GT, I think there might be a defective/bad batch.

[Q] What the hell is this dip in my battery life?

So, at some point I turned off my phone and I -think- the sudden spike down in battery life is around that time.
Anyone got any explanations?

Mine has done that as well a couple of times. One time I had a charge of around 75%...rebooted my phone, and the battery was down to 15% percent.
Maybe it's just another bug we'll have to deal with until they come out with a fix.
thats strange mine doesnt have that much of a dip
every samsung product I have does this, gt 7, gt 10.1, droid charge, and this one. I don't recall my og droid, evo 4g or 3d doing this.
All phones show a dip when there is a battery pull while the phone is on....

Wasn't a pull, just a shutdown and reboot.

Stock battery stats lol
**** didn't notice that graph at the top.
Sent from my SPH-D710 using Forum Runner
well if your phone was rebooted then that bald would have been reset because it displays monitors since last power-on.
there seems to be a bug where the cpu fails to underclock after a certain amount of usage and/or load. rebooting after intensive apps and/or before leaving the phone idle for extended periods of time seems to solve the problem for me. yes i get that too.

just press on top after you press battery usage on the screen that shows you the battery usage.

Is anyone else's battery on crack?

Usually I can go a full 16 hour work day without needing an extra charge, then last week it started not holding the charge so well. In fact Tuesday it had 30% and I left the house for half an hour, and when I came back the phone had shut off and was at 0. I hadn't even touched it. I am on a mix of Wi-Fi and LTE. Anyway, that was odd. Now look at the battery usage...

My android system has been going crazy the last week or so, usually would be at 5% our do but lately has been 40+ easy... been to lazy to wipe and re flash as I'm sure that will fix the issue, but lately I've been near power all the time so it hasn't really bothered me.
Sent from my SAMSUNG-SGH-I747 using xda premium
I flashed with Highonandroid and got 30+ hours. Probably could have gotten double if I didn't kill half of it installing all my apps back on.
What rom are you using?
On the stock image I was only getting 9 hours.

if you are not using a phone, turn it off and the battery will hold charge for many, many days.

Major Battery Drain Help!! (100% -> 0% in < 5 hrs)

Firstly, I am fully stock in every way. I have been getting abysmal battery life from my phone.

Obviously I'm aware that the culprit is lookout.. i do like the services offered by lookout and would like to keep them. Disabling lookout does fix the problem but I'm wanting to hear potential causes and/or fixes..
Thanks for your time.
Which of the features does it offer you "like". Many times there are other alternatives for those "features" without the drain.
Im using lookout with no major battery drain. Looks like your wifi was on all the time. Low wifi signal may cause for wifi radio to broadcast with higher power. Smart stay will trigger camera every few seconds. Personally I use "Screebl" from play store - it keeps screen on by checking if phone is not laying flat. Install "better battery status" (need root for that) and it will allow you to see which app or service keep phone awake. Turn on power saving mode. In settings turn off wifi while sleep mode.

Try one power guard https://play.google.com/store/apps/details?id=com.onexuan.battery. and or Snapdragon battery guru. https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app...... also I deleted lookout since i also had crazy batter drain I went from 100% to 88% in 45 minutes.

Thanks to those who replied. . However none of the answers have helped. .
Like I said, I am hoping to keep lookout as an unrooted stock user .. for now.
What isn't adding up is the fact that most users are reporting no issues with lookout draining battery..
So why am I having problems ??
As for weak wifi, that's not an issue.
Other ideas ??
I had the exact same issue. The only way for me to stop that was to uninstall it unfortunately

I keep finding Play Music running on its own and eating battery quite often. Maybe that's the culprit? Was happening lately on my Note 2 as well.
I had this issue just after using Root de la Vega. My battery was going completely dead after about 4 hours with light use and the phone was getting really warm like the CPU was pegged the whole time. I did a factory reset and have all the same apps installed and my phone now makes it easily through a 10 hour workday and 45 minute commute with heavy use (5h screen time). Try that if you haven't.

Battery help.

I've noticed a sharp decline in battery. With only 35 minutes of screen on I've already lost 11%. In this case, index service seems to be using a lot of battery, but this is the first time I noticed that. I was getting like 7 hours of screen on, now I'm getting about 5.

IndexService works hard when you add new docs/books, it scans all of them, then it should go away. For some reason it didn't find 1 or more files on my SD card, kept scanning for hours. Did you add anything new to tablet?

I downloaded a powerpoint and then converted it to a pdf. It seems like it just won't stop. Everyone I look at its running time it is increasing.

You could delete recently added/changed files and see what happens.

I restarted and now it seems like index service is still running frequently, but no longer nonstop. Regardless of index service my battery still seems to be worse by 2 hours. It was awesome for the first couple weeks and now its just average. I don't even have that many apps.

if you're rooted just freeze the indexer.

I'm holding off for rooting until Knox is circumvented. Plus I don't see recoveries or custom Roms yet so I don't have all that much incentive.

Gap in battery stats

Anyone know why I'd have a gap like this in the battery? Normally I would assume a gap like that would be from the phone being turned off but my phone was never off as far as I can tell. The up time is at about 17 hours right now and the last time I unlocked the phone I used my fingerprint. When a reboot happens you have to enter a pin/pattern the first time to unlock. You can also see that wifi was active that whole time. Looks like the cellular signal was off but I have wifi calling turned on so I never pay attention to cell signal in my house. I think I've seen this one other time before and had no explanation. It's almost like the service that monitors the battery wasn't working. I'm running stock, decrypted 6.0.1.

This is the 5X. I charged it up right at the beginning of the weekend and then used very rarely which is why it looks like it would last 4 days
You rebooted, that's completely normal. Happens all the time.

I've seen a similar thing on the battery screen on my N6 a couple weeks ago on 6.0, never really got a decent explanation, but didn't actually cause any real problem and hadn't occured repeatedly since.
