Bad battery?

I have had some issues where my phone won't wake up so I have to pull the battery and when it reboots the battery drops like 20%. Is this a bad battery or what causes this?

what rom are you running? if i remember correctly there was an issue with one of the roms but i cant remember. but I do remember it being an older rom that did that.
as for the batt. % i get that all the time even when i reboot..tho i get a bigger drop in % when the batter is lower.. like if i was at 50% batt power.. reboot then i would be like at 20% batt. power.. but it would stay at 20% for a really long time till it caught up with it. and sometimes the batter % would rise up a bit. but eventually start to go down again.
But maybe I have a bad battery also.. so im not sure...lol

I had the exact same problem my phone would constantly reboot and shut itself off then I would lose half my battery % I thought it was the battery too so I returned it to stock and took it to sprint they looked at the phone for 2 hours and said there was absolutely nothing wrong with it or the battery. So I took it home and re rooted using Qbking77's latest method the one that does not give you the yellow triangle and I have not had one reboot or sleep of death since and the phone just runs soo much better now so I think it was a bad root for me. I would try re rooting with the latest method and see what that does for you. Also ya out of curiosity what rom are you using because I have heard similar stories from people running the ICS leaks.

In recovery, wipe your battery stats. May help after the phone calibrates.

I'm running caulk's fc07 1.1 with the repacked kernal. It happened to me before on GB while also running caulk's rom but it only a few times. It seems to happen more now. Here is a screen of my battery
Sent from my SPH-D710 using XDA Premium App

I believe this would happen more in most recent ROMs because everyone is focusing how fast we can run it or how long we can use it. In either case, there are lots of tweaks and mechanism to make it fast and last long.
For the battery life, there is some background process monitoring unnecessary processes and kills those or tweaks to less frequently monitor the status. So, if the process which is related to battery life is killed, next time when it wake up, it may detect the different life time based on current Voltage or mA. I'm not an expert in this area but it's highly possible scenario. Tweaking the system brings lots of good things to us but in the other side, there could be some
side effect.
If you want to verify this theory, you can just compare the non tweaked rom versus tweaked Rom.
Be sure that you don't run any battery saver apps on non tweaked rom to measure it correctly.
Attached is my last screenshot yesterday after I removed the battery saver app. Currently I'm using Calk's Stock Rom FC07 (non tweaked version). Based on my test, the battery last longer than when battery save app installed and running.

Cool I didn't know that would be an issue. Well I'll try that thanks for help

Also a note... with my experience anything to do with 3g service... I can kiss my batter life goodbye... if im at 100% battery life.. and i have 3g on... it will last around 5 hours and its dead

Take out your battery, does it look "bloated", "fat"? Can you spin it like a bottle?

Ah, gotcha. I have no idea then, lol. Sorry.

Looks like you flasher a no data one click. What was it running before. Also what browser?
sent from my BAD A$$ Epic touch

OP, I've been having the same problem. My phone will randomly shut down usually while web browsing (Dolphin HD) usually on a mobile network connection (3G or 4G). How it normally goes is I will be browsing and then the phone will shut down to a blank screen, no shutdown animation, like somebody pulled the battery. When I re-boot the phone will usually do a hard shutdown again shortly after booting up (15-30 seconds). The battery level will be different upon re-boot (eg. 95% -> 40% -> 1% -> 30%). Sometimes the screen will briefly flash a low battery warning (1 second or so) before doing a hard shutdown.
My phone is 1 year old, not rooted, Android 4.0.4, Baseband S710.10 S.FI27.
Recently took the phone to a Sprint service location they could not replicate the problem, but tested the battery and did a factory reset. The problem persists after the factory reset.
Attached are screenshots of my battery graph following a series of re-boots.

Bump!! I'm sorry, but I'm having this issue too. My phone is a year old and is pretty much doing the same thing. Tried different ROMs. I'm running the Full Restore FI03 Rooted ROM right now and still doing this. My issue is more crucial. My phone doesn't sleep well, dies in like 6 hours max.
It will randomly force shutdown and won't turn on. It will try and reboot, the screen will flicker and just shut off. The only way I can get the phone to turn back on is by plugging it into a charger.
Luckily I have a portable charger. I wonder if this is a battery issue. Anybody tried using a different battery.

My wife had similar symptoms... flickering screen and shuts down. no animation or warning.. ahd to plug it in to boot the phone again... battery would show 90%, then 15% after a reboot... her battery only lasts half the day, ect.... turns out it was her battery going bad. I bought her Anker batteries on amazon (2 batteries plus charger $18) and it hasn't happened ever since. Its been over a week now since she's been on the new battery.
trust me, just get a new battery, you'll enjoy the better battery life too. its typical to swap the batteries every 8-10 months.

Already bought me a replacement battery. LoL!! Glad to see that was the issue. Can't wait for it to come.

Important, refer to this thread on WHY the battery may be going bad:

takes fuzzy picture and then shuts down

I am wondering if someone here can help me.
I have an unrooted SGIII from Sprint and have had the phone since 2012.
In the last update, to kitkat at least I have noticed some serious battery drain...in particular when I take pictures, the pictures get very grainy and then boom, the phone shuts down. Not cool.
do i need a new battery? I have read all the information about saving battery infact I can hardly see my screen my brightness is so low.
Any help would be appreciated.
Thanks

Try a factory reset after backup what you want.
If that doesn't help, try Odining the stock ND8 tar from a PC, in the development (non-original) section.

n00b-xda-disciple's Wicked X Video review
Sent from my Sprint Samsung Galaxy SIII on TouchWiz 4.4.2 with Conquest: Singularity v2.2, Ktoonsez' latest kernel and the latest Philz Touch Recovery.

I can't tell you that a new battery will fix your problems. But, I replaced my battery after 9 months of use and I was amazed at the difference. Try borrowing someone's battery and see if it makes a difference? If you buy a new battery and that doesn't solve the problem, you've ruled out the battery and now have 2 batteries to switch between

I have this exact same problem. Any time the battery is below 40-50%, the camera could cause the phone to shut down at any time. Really, anything will cause it to shut down, but it seems like the camera will do it every single time. The phone will not stay on after that point unless you plug it in for even 5 minutes, at which point it tells you your battery is 60-70%.
This is the reason I rooted and then flashed the Odin stock ND8 the other day (http://forum.xda-developers.com/gal...rint-galaxy-s3-complete-boot-process-t2829181). I then flashed to Wicked X v7.3. It has only been two days, but the same symptoms persist. My wife has the same phone and experiences the same problems, which all started upon the update to 4.4.2.
If anybody has any ideas, I'm all ears.

how long have you guys had your phone any water damage? hard falls things like that?

Got the phone in December 2012, as did my wife. No hard falls that I can remember. Up until recently I had it in an Otter Box Commuter case. I took it out after I updated and started pulling the battery to try to get things to reset (never worked and like the smaller profile so I didn't put the case back on).
Tonight I installed the Xposed critical battery shutdown module and also Battery Calibration recommended in these posts http://forum.xda-developers.com/showthread.php?t=2781926 and (can't find the thread recommending Battery Calibration by Nema, but whatever). After I installed the module (and I think activated it), I ran the battery down until the phone shut off. Will charge to 100% tonight and start calibration in the morning.

The module does not appear to be working,as the phone shut down at 28% with no prior warnings that it prevented shutdown. That's unfortunate. To activate the module, do I just click the check mark and reboot?

from what I've seen water damage and hard falls can have a heavy impact on the OS(not like crack screen or digitizer but just a hard fall and phone survives) well except on water proof/shock proof phones.....but for the most part if a factory reset/Odin/Heimdall/what ever method back to stock you use doesn't fix the problem its a hardware issue

All's better after new battery
I just wanted to post a followup to my issue. After the shutdown mod and battery calibration didn't help, I bought an Anker replacement battery from Amazon. Since my wife had the same problem, I bought a two pack for $28. I charged the battery overnight and then in the morning hit the battery calibration button.
I noticed a difference right away - I was only down 7% after a few hours at work. My goal was to let the battery run down until the phone shut off, which happened at about the 30 hour mark with my playing HD youtube videos for the last hour so it would die. The battery life indicator actually counted all the way down to 1% before shutting off, which is a stark contrast to the 30% that had been occurring with the old battery.
With the new battery, I've also used the camera when it was under 30% with no problems.
My recommendation for anyone that has similar problems is to get a new battery. They are a hell of a lot cheaper than a new phone, so it's worth a shot.

Galaxy 6 edge good battery life

If you're asking these questions, you probably shouldn't be attempting to root or modify your device at all.

Everything is fine now..... rooting and deep sleep are friends again lol

So if i understand correctly
Reflash S6 with Kies or Odin then Root and this should improve batt life?

Yes. I have deep sleep working fine after rerooting but I also am running the stock recovery file Posted here.
http://zidroid.com/download-t-mobile...tock-recovery/
I have probably rerooted a slew of times for for various reasons. Last method was to first restore stock firmware using Kies method. It will ask for your serial number. If you can get to download mode, puch home key and wrote down serial number you will see there. Ther serial number for your phone is NOT the IME number which Samsung as well as TMobile kept telling me was the correct serial number. On top of that, First level support asked me to remove my battery to finde serial number under the battery. LOL....great support we pay for

seems to be working really good for me so far
havent truely tested the phone out
last night i factory reset my phone rooted then flashed stock recovery then wiped cache
set up my phone disables some bloat
the night before the phone died while i was sleeping
last night it barely dropped 1% so deep sleep is working
right now im at 39% phones been on for 12h 13m since last charge
and i have 2h 30m on screen time,
need to do some more testing. a couple more charge cycles should make it right
how are u guys charging your phone? letting it die then letting it charge to a full 100? or what

Getting pretty decent life myself.

Just look at this
I didn't watch any movies, just plain browsing, couple of messages, 25 minutes gaming and using some apps (Facebook, google + and a couple of news apps).

good stats from your end... but i seem to be having an issue after I:
took OTA
then rooted
went back n flashed stock FW
rooted again
I fully charge last night around 11pm, and woke up around 5:30am and battery was down to 91%... Just now i had to fully charge again since I was down to about 10% ... Any ideas??
UPDATE:
Don't know if this fix the battery drain issue.. But after rooting, flashing back stock FW and rooting again over the weekend the battery took a massive hit. Just last night with about 78% i decided to odin the Stock Recovery. I went to sleep with 76% and woke up to a 74% battery. I guess the stock recovery worked --- but then on my 2.5 hour commute i left the house with 73% and when i check back at my office i was at 55% (browsing, FB and soundcloud player on) I guess that's normal ???

Completely stock and happy with the battery life.

Loving my battery life! Rooted, custom kernel and twrp

Battery discharging abnormally fast.

A few weeks ago i had this weird abnormally fast discharge got the phone at 2% battery for like 30 minites, then 3% battery. So i took this capture.

Sent from my LG-H815 using XDA-Developers mobile app

It's happening more or less the same on my H815. I've tried everything so far: plane mode or not, different roms stock or not, 5.1 and 6.0, dozens of factory resets, even a brand new battery, it's exactly the same everywhere. Phone will suck around 10% per hour even when freshly formated and untouched, even on plane mode. And any application informing of battery stats won't point at anything as the culprit, it's like the battery capacity is suddenly a 10% of what it should be but will still take 1:30h to fully charge. I haven't RMA'd it yet because mine has the bootloader unlocked but I might if it doesn't fix itself soon. What serial is yours? Mine is a 508.
Hopefully, living in Europe means they won't reject the warranty for an unlocked bootloader as it's obviously a hardware problem.

Been there, done that. No matter if I'm using a freshly factory reset stock ROM with all radios activated or a fully modded, debloated, greenefied and amplified CM installation on plane mode. Battery will still deplete at 10% hour with no culprit in battery stats (top one will be Screen with something like 30 minutes on and 100mAh used)

Thanks, I'll try. Even though Better Battery Stats does more or less the same and showed absolutely nothing (wakelocks et all) draining the battery.

That tool has a lot more granularity maybe it might reveal some more clues. Same goes for the OP.
let us know how it goes.

CM you get what you get...try Genisys

Does the phone get warm while this is happening?
the way I see it, you either 1) have crappy battery, and phone is normal so doesn't suck down lots of electricity and doesn't get warm, or 2) have fine battery, and phone is acting weird and sucking down all your energy.
If you are situation 2), then you would feel the phone get very warm to use that much energy so fast. If your phone is cool during all this time, then it's not using much energy to be able to stay cool, so you know your battery is having a problem.
maybe try cutting a hole in your pocket and put your phone against your thigh to really feel whether it's too warm.
