Battery Problem? - Samsung Epic 4G Touch

Hello,
My battery life hasn't been so great as of lately. IDK if it's ICS or if because my battery is nearing the end of it's life but sometimes my phone reboots and I lose like 30% battery out of nowhere. Is there an app that anyone can recommend to test to see if a battery is still good?

Its kinda an issue with our phones from what i can gather. It seems at 50% or lower it will drop in large numbers when it reboots. I read if u have to reboot to turn on airplane mode before reboot. They say its a fix but i can not confirm.

Not sure if it's an app to test if your battery is still good but you can test if your battery is bad by taking it out and see if it's bulging on the sides.. Also if you let you phone die alot or alot of deep charges that will kill your battery (its best to charge our batteries as much as possible for long term health)
In the meantime you can grab GSam battery monitor from the market or better battery stats to see if it's something chewing up your battery

Are you stock ics or are you on a custom Rom ?
If your stock ff18 ics, this is as good as it gets. If on custom Rom you may have options to tweak settings and save some batt, custom Rom wise the better ones are near stock, the more bells and whistles custom roms have the greater battery hogs they are.

ICS battery drain? 15+hrs on Gingerbread, down to ~6hrs on ICS?

I just installed ICS a couple days ago and have noticed a dramatic decrease in battery life. I was able to get a full day without charging on Gingerbread, ~15+hrs or so. Now on ICS I am maybe only getting half a day. After 5-6hrs, the phone is about ready to die with any use. I was hoping it would get better after a few days but it doesn't look like it.
I have attached a screenshot of my usage this morning. I talked on the phone for about 5-10mins, and played some games for maybe 10 mins or so, sent a few e-mails, and did some light browsing. All pretty normal use for me. Before I would still be at 80+% still, down into the 50's right now.
Whats gpsd and why is it using so much?
The gpsd is a GPS like service on your phone. Someone correct me if I'm wrong. Also, Did you calibrate your battery? That might help

Turn off gps until you really need to use it. It's a bug that keeps gps actively searching for a signal and that will drain your battery quick, as well as make your phone super hot.

When i had fb17 on my phone it showed gsdp running even with GPS off
Thanks guys, my phone has been super hot! I turned GPS off, we'll see what happens....
How do I calibrate my battery?
There's no need to calibrate your battery, I did notice yesterday that GPS was on even after I turned it off, but that was after using Google Tracker for a jog. I simply restarted my phone and it was fixed, lets not forget that this is still in early development. Although I will say that now on my third day with this rom, the battery is getting better by the day! Good luck and Happy Flashing.

Yep keep your GPS off and your battery will improve dramatically. When it works, it's a major battery drainer. We'll need to wait for a build further down the road for a fix.
The answer to your question essentially is, you don't. This phone has an auto-calibrating fuel gauge that makes previous methods of battery calibration (wiping battery stats or using the battery calibration app) useless.
For the one "possible" way to calibrate the battery on this phone, see this ...

But I don't think this is you issue. Turn off GPS for now and you'll be good to go.

Agreed. Turning off GPS helped out with battery life dramatically on my phone. (FB17)

how long have you had the ROM flashed? it may take couple of days to have it settled into the new system/software. give it couple of days with the same cycle of usuage/charging times.

I had the same problem but after a quick reboot it stopped, and even with the gps off the 3G/4G will still show location just no navigation.
Hell no BS i get 4 MAXXXXX hours with the fb17
On CM9 3.1 with Steady's FB15 Kernel and the FB15 modem I get about 1/3 to 1/2 of my previous battery life. The estimated mAh draw is also in that neighborhood.
From what I can tell it's mostly low level stuff that is causing the drain, stuff in the kernel and Trebuchet launcher. Exactly what I expect from early, un-optimized code. With time I fully expect that I will my old battery life if not better as developers get the time to work the bugs out.
I can't discount that some of my apps are partially incompatible with ICS and causing wonkiness as well. It also doesn't help that I enjoy ICS so much that I can't stop playing with it.

A rant about my experience with the Verizon Galaxy Nexus. HELP!!

Let me start off with the good in this rant. This device is BEAUTIFUL and has A LOT of potential. Considering i just rooted it, it is even more fantastic BUT (there is always a "but" in life) here are my issues that i PRAY would go away. For some odd reason, though i have done everything i can to prevent it from happening, the battery life is just terrible! And here is the mind blowing part: My brightness is always at about 15-30 percent, my automatic sleep is at 15 seconds, i am never on 4G, NFC is off and my GPS is almost, always off. I recently learned that having a lot of black (Wallpaper, themes or simply a black display) going on prevents the display from eating up battery, therefore i've blackened what i use most (MMS, Gmail, Instagram and of course a black wallpaper) but after all of that, the battery still tends to suck major ball sack (sorry for the vivid image). If you must know i am using an AOKP rom, Jelly bean. I absolutely love the rom.
On behalf of that rant ^ .. Is there anything anyone could/would suggest i do in order to have a better experience with battery? Maybe a different rom that revolves around better battery life? Anything that i am missing to prevent battery from draining so fast? AM I THE ONLY ONE GOING THROUGH THIS?!
Last but not least, what gets me going and makes me want to punch something is the fact that my phone constantly, CONSTANTLY heats up for NO REASON (i'm assuming theres an actual reason but i have no idea what it is). After a full charge, i'd unplug the device and couple mins in after browsing web for like 60 seconds and texting, it'd start burning on the top of the screen and the back where the camera is. What is that all about?
And on behalf of that second rant ^ .. is there a solution for that? AM I THE ONLY ONE GOING THROUGH THIS?! lol
:crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying:
Check out what my battery looked like after a few mins from unplugging it. Screen, 67% ??????
Believe it or not... I had a battery go bad already on me. Now i was short charging it and stuff like that.. but still. The early builds weren't as efficient as this one is. You might try a new battery. Or the oem extended one. I have had good luck with both routes. Oh, and i'm stock.
Lots of battery drain and a hot phone means that it's trying to do something. Looking at your screenshot, you're not having any signal problems, which would lead me to believe it's a rogue app. What was your total screen on time during that 48 minutes?

i honestly don't remember, i THINK it was probably 32 mins because thats what i see every time i see the battery that way. If that makes any sense.
Which kernel are you running with that rom? I had a JellyBean rom with a kernel that increased overall, but my phone would often heat up and battery life was not the best. Changed roms and kernel and everything is cool now.

32 minutes of screen on being 29% of your battery. That makes roughly 110 minutes of screen on for the entire battery. Running a stock battery? I never did, but I think people have said 2 hours screen on is the low end for a normal battery. I could be wrong, though.

Or the high end. I got mine as a replacement device for the Droid Charge, so I had to order a battery and back cover when they offered it to me. Since VZW had a 50% off sale on the 2100mAh battery and back, I went with that. So I've literally never used the standard OEM battery with the phone.
Try going to this link: http://minooch.com/franciscofranco/Galaxy Nexus/JB/Jelly Bean/
and downloading "franco.Kernel-r225-384GPU.zip" flash it in recovery like you would a normal rom. Franco's kernel is extremely stable and works magic for good battery life. Should also resolve your overheating issue. If not, I'd suggest a full wipe and installing a different rom.

Terrific! So no need for a data/cache wipe? I can flash this over the current ROM I'm using? Backup I'll do of course but yeah.

I normally wipe cache, not sure if it's required. But yeah, it's not a new rom or anything, just different kernel to test out and see if the kernel is what was causing your battery issues.
I'm using the jbsorcery beta with the lean kernel and under clocked with the modded voltage and this is heavy usage on Facebook and texting and about 30 min on the phone I have about 2hrs 45min and im at 80%

[Q] Any way to Increase battery life?

I'm just wondering if there's any known methods to increase the battery life without sacrificing performance. I know the basic stuff like turning off Gps, Wifi, Data, etc. when not needed but is there anything else I can do to prolong the battery life? I'm currently running the wanam lite rom with trininty's alpha 7b kernel. A couple of people reported great battery life with this combo but I'm only getting a little bit better than stock battery life.
What exactly is a little bit better than stock? How many hours are you getting?

Well with moderate use ( 3-4 hours of web browsing, playing games, etc.) on stock I get about 9 hours and with this rom and kernel I get roughly 9 and half.

Yeah, The rom is based off of stock H2 and is supposed to have some battery tweaks to make it last longer. All of the people said battery was good using this combo and 1 person said it's been 1 day 16 minutes, and they had 26% left but they didn't post the usage.
Ok this is with the stock rom. Heavy usage by my means any way. It was on the charger for a few mins here and there. But really not enough to show real battery increase.

The best way to determine battery life (not I played a game for a little, surfed the web over 4G, called some, texted all day) is to take a screenshot of your Screen On time, and overall time since charging. Otherwise, your statements are pointless.
If u have a rooted device u should try the highonandriod Rom it dies have better battery life than stock

I'm very happy with Wanam Lite for now, it's so far the smoothest stock rom I've flashed and I'm eagerly awaiting the next update, so I don't really plan on flashing anything else for now. Thanks for the suggestion though, I'll definitely give it a shot when I'm looking for another rom to flash.
Disable auto synchronize. Thats the key.

Don't use the phone. The screen will almost always be your biggest power draw. Screen-on time is relevant because if you have the screen on for three or four hours you aren't going to see battery life that is any better.

Your right, it is relevant when comparing, but I'm not comparing anything here just looking for tips and tricks. I looked at battery stats when I compared the stock battery to the rom battery and recorded both stats on heavy use. If you want statistics, I got 9h 38m of battery use, internet and netflix took up 31% battery consumption, games took up 23%, phone calls and texting took up 12%, and the other 34% is basically screen off time. These were the stats from when I tested it on the Wanam Lite rom. I'm not confused as to why it only lasts about 9 and a half, hours as you can see I was constantly on the phone when I was testing it.

Well not only were you watching a video (I assume, instead of just browsing) Netflix, you were streaming. That probably did a number on your battery. I know I cannot stream Netflix for very long if I want my phone to last through the day. Also games, things that will ramp up the processor, etc while using the screen will tax your battery more than usual.

Some may not like my answer because it removes some bells and whistles, but I suggest turning off all the motion features. Just my two cents. Battery life was better and I found most of the motion features unnecessary.

Yeah, this isn't my everyday use, nor would I do this if I was trying to maximize my battery life. This was purely for testing the battery life on heavy usage and I found that it was only a little bit better when compared to stock. I'm in no way complaining, I think Wanam has done a amazing job with the rom. The stability is great, speed is comparable to JB roms, and battery is a lot better. Unless used heavily as shown above, then it's only slightly better then stock which is kind of odd but makes sense. I was just wondering what all a person could do to maximize their battery life, that's all.

No worries! If you have trouble with idle battery drain, something like Juice Defender will help a lot if you're going to have the phone idle for extended periods of time. Other than that, all I can think of is underclocking (I run at 1350), and sometimes overclocking your min-CPU speed can help as well. The thought behind this is is that the CPU will be able to finish tasks faster, even if slightly, and then be able to go back into deep sleep. I know a lot of people on the Galaxy Nexus forums run 700min, 1000max because of this.

Thanks, I actually didn't know that, I also heard undervolting can increase battery life and reduce the battery/phone heating up but someone said that it can it will have a major effect on the CPU, not sure if it's true or not.

[Q] Battery life

Hello.
I was wondering if my battery life is low or not, so I want to know what your battery life is guyz.
My battery would last like 12hs with wifi always on and facebook, some music here and then and youtube. is it a normal consumption ?
There are so many variables that come into play with battery life that is nearly impossible to quantify what sort of battery life someone should be getting. Screen on time, brightness settings, radios used, reception, usage patterns, apps running in the background....tons of things that will be different from person to person. Also, the actual battery itself comes into play with how well it can hold a charge.
As long as you are happy with your battery situation, all is well. If not, perhaps look into what is using your battery. Better Battery Stats can potentially help you narrow down where things on the software end are draining your battery.

That's about what I use to get.
I went out and bought a spare battery. I'm not a fan of extended batteries so I went with a standard battery for about $10.
I also flashed a new kernel that will help on the screen brightness and underclocking.

[Q] S3 Battery drain during use

I know there are hundreds of these threads but i was unable to find the information that I'm looking for. But my guess is there is no real answer to my question. But i've been wrong before. Please bear with me
Here goes.
I want to know how to maximize the battery when USING the phone. I dont care about wakelocks or sleep time etc.
I am interested in getting to max out the usage time.
For example when I stream radio and surf the net and text. My phone lasts 2 hours with max birghtness. That seems really short.
- I've done all that I know to minimize power consumption with turning off sync, settings, etc.
- I have tasker starting and stopping data during screen on/off.
- I have the phone UV and under clocked.
- I Limit my phone to 3G only, with no LTE
- Also signal is not a problem since I can stream and surf without an issue. With areas with poor reception. I don’t even use the phone really
-*I also have all the chats turned on include facebook, whats app, etc. Once again, phone is awake. and I'm concerned with its ON screen usage battery time.
- I even have the second CPU setting on conservative. (when set on ondemand it drains even faster)
But during usage, its terribly short! What can I do to prolong the life?
The battery was always like this and I dont believe its defective. With regular use, checking phone (once or twice every hour) can easily last a day. But during multitasking usage I notice the drain to be 49-59% per hour according to battery spy.
I know I can uninstall battery spy/BBS to conserve battery. But I'm looking for what some are reporting (4-5 hours of on screen usage time).
Looking for some guru-like advice Thansk in advanced
Personally, I get the best battery life out of the stock kernel of whatever particular ROM I'm running. I stick with tw based ROMs, and I greenify almost everything! I consistently get between 5 and 6 hours of "screen on" time with the stock battery.
You never said what ROM and kernel combo you're using. I know that I get 3 to 4 hours of screen time depending on the apps used and the connections utilized (wifi, signal strength, LTE or H+, etc). 2 hours definitely sounds low though. I'm using stock debloated ROM right now and stock kernel. I have not modified voltage or clocking in any way (yet).

I'm using stock debloated ROM right now and stock kernel. I have not modified voltage or clocking in any way (yet).

You're doing heavy multitasking!! It's going to eat the battery, sorry, but no one's going to post a magic "cure" to increase battery life! Buy an extended battery... Problem solved.

Websurf and radio or text and radio is just 2 tasks occuring.
Well I can say that running on Wifi, I can get regular battery life about 4-5 hours of use and over 20 hours of idle time.
The radio seems to be the main culprit, so the question is..... what can be done about that?
I'm asking because
- I flashed diff modems and seems to yield same results
- other S3 from my friends seems to last longer with multitasking
- signal....strong or weak seems to produce same drain.
Battery?

I've had the same problem. I couldn't get the same battery life as others I know. I always turn my GPS off if I didn't need to use it. Google now seemed to kill my battery so I stopped using it. But, the one thing I did notice is that the battery stats can be a little deceiving. If I left my phone off the charger and didn't use it for 10 hours and then started to play a game, it would look like I was getting good battery life as I would have about 60% battery left. Now if I played the game right after unplugging my phone, and then after the same 10 hours I'd be around 40%. Hopefully that makes sense.
One thing that I did do to overcome this was get an extended battery. It does add a little bulk, but now I can use my phone like I want and not have to worry about my phone dying on me at night. I can even forget to plug it in and still have battery the next day. For me I got the hyperion 4200 battery. The Zero Lemon seemed just to big for my tastes.
The other thing is also the ROM. At times I have found the same ROM but a different version exhibited different results. All ROM's offer something different so it is a give and take situation.
I hope this helped.

Yea my gps only turns on when my map turns on via tasker. I also dont have google now on.
Ya i understand what you mean on the percentages.
Ive seen people wiht great battery life, i wanted to try to acheive that without an extended bat. I was wondering if there was somehting that was obvious, or some radio battery drain fix. (I even tried only 3G, and still drains)
Thanks

It's a little hard to compare, but right now I'm on a 4.3 ROM and the battery life has been exceptional. Otherwise the next one that has been closest for me in terms of battery life has been Dandroid. Also, it's hard to judge a ROM after a day.
I guess I should have asked if you have tried or have any interest in a custom ROM.

I tried customs like AOKP, PA, CM etc before. I dindt notice a gain in bat life.
I do enjoy's stocks stability so I would like to find a solution with my stock phone. But doesnt see like theres one....

I've had a hard time getting really good battery life from the stock ROM. At best using greenify, I could prolong it a bit. If you are interested in a stock ROM with some tweaks, I always suggest S3Rx, or Dandroid if you want a slimmed down version without the bloat.
You can always try the power save mode as that does seem to help some, but you may experience some lag.

Ive frozen most of the bloat, greenified everything, plus I unclocked and under volted it, so any lag I would feel from power safe wont affect me since i believe power save throttles to 1350 ish .
