Random reboot battery level drops - Epic 4G General

Hey I was wondering if anyone running any GB ROMs experience huge battery level drops when/if they experience a random reboot or reboot manually (sometimes). My battery will appear to be doing great until the phone is rebooted and then the indicator drops to the bottom...the interesting part is the indicator will always boot to the same level (30%) no matter what level I was at b4 the reboot. I've experience this with both hurricane and stockyish ROMs. I tried resetting battery stats and that ddnt help...

That is a bug in CWM and battery level reporting. You can get your battery level back by either rebooting with a charger on or pull the battery out for 5 minutes and reboot.

Worked! Thanks!

i didnt think that it was a CWM problem... b/c i have noticed that since when i first got my epic on release day..

same thing just happened to me but im still on SFR Froyo so i dont think its a GB Rom, but i did the put the charger in and rebooted.... worked great thanks!

Glad I could help. Didn't realize some people saw this on stock. So it may be a reporting issue or momentary voltage drop. Either way at least we can work around it.

[Q] Phone has about 1 minutte of battery life

Hello everyone,
I rooted my phone in early september and put cyanogen 5 on it. I loved the new features but the speed wasn't very good so I switched to biffmod. That's when the problems started to happen. My battery life significantly decreased, I could barely keep it running for 4 hours. When I would open apps like google maps it would turn off instantly, but the phone and text messages worked flawlessly and I loved the speed so I didn't really mind. In the last few weeks it got worse. After a phone call the phone would turn off. I decided to reflash but it stayed the same. Now the phone lasts about 1 minute after unplugging from 100% charge. Anyone knows what could be causing this? or how to fix it?
EDIT : I'm using Biffmod 2.1 with 245 CPU minumum frequency and 556 maximum and DangerSPL.
is this happening on other roms or just biffmod??
Cyanogen 5 was working fine, only hapenned since I switched to Biffmod. (Which is using cyanogen 6)
do a nandroid (plug the phone in for this so it keeps power). then try another rom i say. we can then narrow down whether it is a rom issue or a battery issue. as far as i know no rom should give your battery a lifespan of 1 minute. make sure you have wiped your battery stats too. not sure if this will change anything but you never know.
Looks like a battery wipe fixed the problem. It got past the 1 minute mark! In fact I didn't even know that RA's recovery had that feature. Thanks!
no problem man. i figured it may have been something like that. if the stats dont match then it thinks the battery is low on power when it isnt.
False alarm, it did get better but it shut down after 30min of idle with wifi on.
ok. try a different rom to see if that helps or try draining the battery completely. keep turning your g1 on until it wont turn on any longer. then try charging it from there.
how long have you had the phone by the way?
I got the phone 1 year ago. I'm trying to drain the battery right now. I'll try switching rom after this. Do you have a recomendation? I'm on ebi1 radio.
not sure myself mate. i went for cyanogen, then went to superE as it suited my needs and aint changed since

Fix for poor battery life on dj05/dl09 (rooted)

Hi all I did this last night and it worked wonders on my battery. Before this with screen brightness at about 20% and 10 hours of being on the battery would be dead. The screen on time was 3h15m at best before it would die. After I did this I tested my battery by playing a movie, games, web and texting. When I put my phone on the charger last night screen on time was 5h flat. I was amazed. So I thought I'd type this up for anyone with battery woes. You need to be rooted and Clockwork installed.
1. Dial *22899 and let it do its thing. This helped my battery drain while in standby. Now drains about 1% every 3 hours of standby.
2. Charge phone to 100% (phone on)
3. When the charge hits 100% power down the phone
4. A green battery will show on screen and show its not fully charged. Leave it on the charger until it shows 100% (phone will vibrate to let you know and state 100%, do not unplug phone)
5. Once it reaches 100% boot into recovery by holding both volume keys and power until the Samsung logo appears.
6. Choose "apply update.zip" (use the home key for selection)
7. You are now in Clockwork. Use the volume keys to navigate to "advanced" and the back softkey to select it.
8. In the advanced menu select "wipe battery stats" (there will be no conformation)
9. Back in the advanced menu select "wipe dalvik cache"
10. Now back into the main menu and select 'wipe cache"
11. Select "reboot phone" and wait for it to reboot (will take longer than normal)
12. Once fully loaded unplug the charger and run the phone until the 5% warning then plug back in
So, it sounds like this battery issue only affected those that were rooted to begin with and had to manually clear thiese caches?
I have not noticed any different (good or bad) with my battery on stock only builds DI01 to DL09.

Yea mine kinda went south after I flashed Dj05 awhile back. Alot of users are reporting worse battery after DL09 too though so I thought this may also apply to them.
Battery life is also affected by your kernel and rom combo. Adyrnalyne's kernels seem to have awesome battery life. I last charged my phone saturday night and it's just now dropped down to 17%. However I also did a full wipe including battery stats and davlik when I installed superclean and this kernel.

Yea Ad's were best for me too im on Blackhole 2.4 and Ad's 12/30
Did not work for me
I tried doing this multiple times and it did not work for me. After updating to DJ05 I started to have problems with my battery draining extremely fast (about 3x faster than on DI01). So I upgraded to DL09 thinking it might fix the problem, but it did not. What did work is draining the battery down to 0% and the phone shut off. Then I plugged the phone in and held the volume up/down keys and power button to get in to recovery. I then applied the update.zip to get in to clockwork recovery and scrolled down to the advanced menu and wiped the battery stats. When I rebooted the phone the battery drain was better than when I was on DI01. Not sure if this will work for anyone else but it worked for me.
Yeah, wiping the battery stats when making any major changes seems to help a lot.

I did that too and it didnt help until I wiped battery stats AND cache
Typically I always charge to 100% with the phone off then wipe stats whenever I install a new rom. Was curious why my standby was killing battery on DJ09 and not DJ05, so that *22899 reset helped a bunch.
I went from around 68% no signal from standby to 28% in the short time I've tested.

gonna try this. I was on DL09 for awhile but battery sucked. went back to DI01 but couldn't handle the GPS issue. Going to try this and see if it fixes my issues w/ DL09 and battery.

this worked for me... I has previously just tried wiping battery stats to see if the battery life would improve. I had also changed kernels and switched to dj09 modem so I want sure who the culprit was. I also tried another corrective step by letting the batery drain to zero then turning off and charging to 100% before wiping batt stats but that didn't work either. I am back to normal now which was already pretty good. I should have never messed with the settings in the first place but was curious

so you did the drain then wiped battery status?
jv
I can't believe I didn't know this before. Huge difference. My method was pretty much like the first post. Totally drained battery, dialed the reset number, charged phone to 100% while off, unplugged and replugged until fully charged, wiped battery stats and caches, and I'm still draining. At 43% after 19 hours of lighter use.

Not sure if *22899 fixed my battery issue, but I have now been at 91% after 1 1/2 hour WITH wifi enabled! I've received a few emails only. Not really been messing with the phone. Seems to be alot better then the first time I had DL09.
jv
After a few downloads, a few google talk sessions and more pushed emails it has been 3.5 hours since unplugged and I'm at 80%.... I'm going to have to say that it was the *22899 that helped me.
jv
ahhh battery goodness again
Battery life is worlds better after doing this.
I would go through a fully charged battery in under 6hrs before... as of now ive been on battery since lastnight at 8 and even after a night of usage, no charge overnight, and using it all day today I still have 28% battery.
Thanks a million

You only dialed *22899? didn't do the other steps?
I tried dialing *22899 and it says programming and it reaches to Lock Code password set... and it seems to not be doing anything. Is it done?

Yup. Well I did wipe cache. Don't remember when I did it, though. But at some point after updating to DL09 I did wipe cache. It's been about 2.5 hours since I edited my last post and I've only lost 10% after a few emails and some text. I've even had wireless on since unplugging it. Something fixed it. I did flash a different modem. I flashed http://forum.xda-developers.com/showthread.php?t=908451
jv
edit: forgot to mention that I am using Adrynlyn's test2 1/16 voodoo5 kernel
My results were for dialing just *22899, without doing the other extra steps...
so far 8 hours unplugged from the charger and I'm down to 71% which seems a bit better than previously ...
This worked great. I charged last night to 100% and then this morning wiped stats around 6:30. I have been using it all day with WIFI and 25% brightness and 11 hours later I have 73% battery life left. I also noticed Standby is on 18% which is a lot lower than it has been in the past.
Thanks again for this little tip.
Any idea if just the *22899 will help out a non rooted fascinate without wiping the battery stats? My wife doesn't want me to mess with her phone.

Taking my device to service center tomorrow IST.

I've been having strange fluctuations in the battery which I noticed and I was assuming it was some of wake locks or alarms causing this drain.
I also noticed the battery getting heated during charging.
The weirdest issue I faced is that every first boot after full barge reduces to -10%later reboots meet them intact I noticed this on stock rom and custom rom also, Also while charging I saw that from 93%to 100 %jump was just in few min which is totally ubnormal.
Tough my fast charging was turned off.
Hopefully it's just a battery issue I can't live without this device after giving it for service.
Is anybody else having these issue ??
I think its a software issue did you try doing a factory reset ? Disable all the useless apps? Remove the battery once in awhile? Jumps from 93-94%to 100 is not uncommon

I guess this has been fixed by resetting the battery gauge after full charge to 100% I had to pull the battery wait for about 3mins and put it back after this reset procedure looks like the last 2 charge cycles dint have those random drops after reboots, but I've the battery drains I need to figure out what problem is I get a maz of 4hsot.

@Pratik Thanks your suggestion, I already Did this, Flashed Stock was on Stock for some time approx1day could not bear it flashed our Rom all is good so far needs a bit or battery tweaking.my app usage always is 60%> so it may take a while for me to understand on how this can be fixed.

Battery reading issues

Hey everyone. So I bought a second hand note 4 recently and have been having battery problems.
I did a full wipe install of CM13 and the battery dropped to 0% at random times and I had to plug it in the charger for the phone to even boot as it would just restart as soon as it turned on. Anyway, i thought this is probably due to faulty battery. I purchased another one and now this one doesn't reboot at random times but seems like the phone keeps reading the battery percentage wrong, sometimes it doesn't charge over certain percent, just gets stuck at 77% or 63% or any percentage really. If I remove the battery and plug it back in, it shows a completely different percentage everytime. I have tried wiping battery stats, do a full discharge/charge, nothing seems to help. Battery drains fairly fast too, once I manage to get it to 100% it shows that expected time is like 2-3hrs if screen on. Thanks!

battery displaying different percentage after u remove it and put it back in is normal i have 3 note4s all do the same (up to 10 percentage change, it either increases or decreases) but the other issues like getting stuck on a certain percentage are not normal make sure u have the genuine battery and try stock rom.
yeah, i tried stock and the same thing really. such a random issue. I just noticed that battery charges once I turn the screen on and use it , so it only gets stuck on random percent only with screen off.

yeah, i said I wiped battery stats, which is basically recalibration
once the battery is charged to 100% it also drops first 10-20% really fast and then it gets better but still I only get around 2hrs screen time

Oops my bad..Didn't read your whole post...
the only way to fix this replace your battery by new one
i tried all options (Format ROM - Wipe battery status - Getting back to stock ROM - Unroot - re Celebrate apps - Changing recovery-Removing battery from device for while sleeping - charge without fast charge - charge via USB)
i asked myself after that all of this headache doesn't worth 20$, i replaced the battery with new one and its working fine now

yeah, i replaced battery as well but it's still the same issue. old one at least charged fully but would randomly reboot on me, the new one doesn't reboot but drains extra fast and doesn't always charge fully. can't believe both batteries are faulty
I am sorry for summoning this old post but did you find any solution to your problem? I have exactly the same experience with my note 4.
Thanks!
Is there a solution for this problem?
Power down and then out-and-in same battery and my stuck-at78%... was 100% when started.
if you having problems with auto restarting.... download the app " WAKE LOCK" and put it on Partial Wake Lock setting... your restarts will be a thing of the past.

Battery level stuck

Howdy, everyone!
I have a problem with my G935F: the battery percentage stays stuck while the device is on, it gets updated on reboot but then won't change. If I connect the phone to the charger the icon in the status bar reflects that but the charge level still won't update until the next reboot.
Battery life is great and charging while the phone is off shows the correct percentage throughout, which makes me believe this is not a problem with the battery.
The phone is rooted and I'm on stock 6.0.1. I've already tried multiple full wipes and flashing several versions of the stock rom (including Nougat) but the problem persists. I've also tried clearing the cache and the dalvik cache to no avail.
Do you have any ideas about what the problem might be or what steps I may take to try and fix it? I'd like to rule out all possibilities before dishing out €50 to have the battery replaced!
Maybe you have an app that's interfering with the reported battery level. Does the battery indicator update properly when you boot the phone into safe mode?
Unfortunately, no.
No ideas?
Unfortunately the battery level is still incorrect even when the phone is booted in Safe Mode. However it is correct when the phone is charged while turned off and the battery life is normal, which makes me believe it's not a hardware problem...
Hey guys sorry to bump old thread , but found this thread and its good to not always make new threads Well, i also suffer some heating issues but recently my battery percentage stuck at 82% while i was charging with hotspot active , i dont know why it got stuck , but when i replugged the jack in usb port , it continues but after sometime stucks again at 84% , i cleared cache partition but its still the same. But if i turn off the phone and charge, it will proceed to 100% , so the only changes that i made in system are enabling developer options and installing nova launcher and xwidgets app , phone is not rooted and completely stock. Any hints guys ?
