Hey Everybody,
for quite some time now, I have experienced some horrible Batterylife on my G2, going from 100% to 30% in less than 3 hours with 40 minutes screen on time.
As if that wasn't bad enough, once my battery drops below 40% my Phone can crash at any time and wont boot up again. When i go into recovery TWRP shows me something of 12-8%.
Charging it for a few minutes and then rebooting it sometimes puts me back at 80%.
And then, as you can see in the attachment, the G2 saying its at 25% while the settings show over 50%.
I have to say I flash a lot of Rom's, switching from AOSP like blisspop to Stock like cloudy G3 and back.
Could this have an effect although I always callibrate my battery after flashing?
Thanks in advance
Its hard to say as old as the phonez r now its about time for the battery to start breaking down internally. Im surprised most of them have lasted this long

running a flashed stock 4.0.4 ICS ROM, Rooted.
everything was running great. battery life was one of the more amazing parts of this tablet. then one day last week i had it on the charger half the day, went to go grab it, wouldn't turn on.
after lots of button pushing, swearing, about 30 minutes of it, i put it back on the charger. 10 minutes later i got a blue battery symbol charging and i held down the power button for 30 seconds and it turned on. since then have had no issues with it working, except battery life is poor. the initial time after i used it, the thing lost like a percent every couple of minutes just sitting there. it was dead within an hour and a half or so, barely touched.
i charged it fully, and reset the battery stats via battery calibrator (even though google says that is useless), then i let it drain to 0 with usage and charged it up again. now the battery life is pretty average. i lose about 10% every half hour on wifi browsing the web, screen at anywhere from 15-30% via Lux, and checking to see if anything is running nonstop in the background. so that gives me only 5 hours of total battery life just browsing the web. before i was watching HD movies 2 hours long on almost 100% brightness with some browsing and messing about in the middle and losing 20%.
i have better battery stats installed and the tab is going into deep sleep very well. also it is barely utilizing full speed, it is rarely at 1.2ghz, usually at 500mhz or 200mhz if not deep sleeping.
a couple times i had some partial wakelock issues but nothing bad. but every other day, the battery life just goes fast just doing regular stuff. nothing unusual going on in the background.
anyone else have this happen?
if i do a full reset can that help? or is this a hardware failure and time to call samsung.
The best battery life I have ever had was on Quicksilver 0.9. I got about 13,5 hours with the display on (WiFi off and airplane mode on)...
On a stock rom u should get about 10 hours with the display on.
On cyanogen-mod ROMs I am experiencing the same thing as you. The battery is dead after ~7 hours.
I would suggest to restock the tab, wipe it and just run with the apps you really need. Maybe even try Quicksilver and to be 100% sure u could even flash the ROM when the battery is at 100%.
What does the battery stats in the settings-app say?
battery settings shows nothing that could be a culprit. this thing deep sleeps like a champ.
screen off just laying around i won't even lose a percent an hour. just all of a sudden i went from being able to browse the web on wifi for 10 hours, to 5. all after that weird time the battery drained super fast.
i wiped cache and dalvik cache, same thing.
going to try reflashing with the newer ICS posted recently. UK Q2 based and see what happens.
P.S. how long until i can post more than once every 5 minutes?
Started last night after I updated a few play store apps. I put my phone in the charger and it was at 1% at the time. I got it up to about 17% and it just stopped charging. I thought it was just the charger (official LG) so I switched it out and grabbed another (Touchpad charger) and it started charging again.
Skip to the morning about 6-7 hours later. Phone is really hot, 75% battery and not charging even though it's still plugged in. First instinct, restart it. At this point I had to get ready for work. When I got to work I let it slowly drain out and waiting about 30 minutes after it died before charging it, thinking that the battery needed a calibration. So I charged it up to about 35% and had to go for lunch. By the time I get back in a little over an hour it's at like.. 10% I think which is pretty odd for that amount of time.
Anyway I let it drain out again, at this point I also reflashed my current rom (dirty wipe), installed betterbatterystats and another app to check wake locks. I also installed greenify and froze 2-3 things. Drain is still happening although it might have slowed a little bit.
Fast forward to home, I have now completely wiped my phone and flashed the latest stable CM on it (10.1.2). In about 40 minutes I went from 25% - 15%. I DID NOT FLASH GAPPS YET. This is running barebones with literally no apps, no syncing (no gapps, no google signin) with WiFi on. I'm thinking the fast drain has to do with A) Uncalibrated battery (I haven't hit 100% in about 48 hours now almost) or B) battery is dead (or really bad).
TL;DR Battery is draining super fast, no [excessive] wake locks, dirty flashed once, clean wiped once. Drain still happening. All in a period of less than 24 hours. Is this a hardware issue?
have you tried a custom kernel?? .. try Franco's i think it's the best for battery life.

I flashed Franco M3 last night before going to bed. I'm going to see how today goes, but right now I can tell you I don't think it fixed anything.

I'll give it a shot whenever it gets low battery today.
you can' really judge franco kernel until a few battery cycle as it need to settle with your ROM.
Hey all,
so after 2 years using my N4 I bought a new battery since I exchanged my display and sort of damaged the original battery (it was bended, smelled strange (could also be the glue) and I had the feeling it performed worse).
In the beginning I was satisfied but now after some time, I have some weired charging effects:
Using the stock rom (Android 5.0.1), I charge the battery to 100%. If I reboot the phone, the battery percentage dropped back to something between 50%-80%. It will the charge back to 100% within a quite short time. If I reboot again, the battery percentage dropps down again, but not that much. This can be repeated several times... Further, if I boot into recovery (TWRP) after reachin 100%, it also shows something between 50%-70%. After changing the battery and flashing Lolipop, I used an app to "calibrate the battery" - don't know if this helped smth or messed up everything.
Furthermore I noticed sometimes, that battery percentage drops down instantly about 20-30% within a sec while using the phone normally.
Is it just a bad replacement battery? Or is it a issue due to Lolipop (can't say if this will happen with KitKat since I changed the battery using the developer preview and stock Lolipop only)?
Right now, I'm trying to charge the battery while beeing in TWRP and see what happens then if I boot the phone.
Edit: Within minutes, battery was up to 100% in TWRP too. I rebooted TWRP and it's now back down to 58%... So it seems that Lolipop is not the reason.
I don't know what the hell is going on with my Note 4 (SM-N910F), but my battery is draining a lot faster then it ever has. A couple months ago i rooted my phablet, tried out two or three different custom ROMS (Omega was one of them), but my Note 4 got so hot it got into a bootloop as soon as I entered my PIN. I reflashed stock ROM and it was back to normal again, but lately it started to warn me for low battery (the 5% warning) and turn off itself in seconds even when i had 20-30% battery left. This didn't happen every day, but it was annoying. So i re-rooted and installed CM 12.1 thinking it was the 5.0.1 and 5.1.1 stock updates. The first night I charged it all night but only got 83% battery when I woke up 9-10h later. Today when I was scrolling FB with 35% battery left, the phone warned me about low battery and dropped to 5%. Is it possible that the battery drain is because the overheating could have caused some damage to the phone/battery? I tried calibrating the battery two times, did everything I could find on the net, but nothing helped. I would like to know if there could be something more than the battery that could cause this because I don't want to buy another one for nothing.
you could try to re-calibrate your battery, you can find a app for that on playstore.
is your phone still getting hot when your battery drain is high?
you could post an image of your battery stats from settings or better battery stats so we can see, why it's empty so fast
I already tried that two times, it did make the battery last a bit longer but the 35%-5% problem is still there. I'm new to XDA so I can't upload the screenshot but I can't see any app or activity that's draining the battery. I've done everything I could find in the forums (lower screen brightnes, turned off auto wake, even downloaded kernel adiutor and changed some settings a guy posted) but nothing has changed.. I'm just wondering if it's the battery that's the problem or something else so I don't fo out and give out money for a new battery if it won't help..
And yes, my phone is still getting hot when the battery is draining fast.. I do have an insurance that I could use but if it's just the battery then I can buy a new one. I forgot to mention that the phone gets pretty hot when I charge it, somewhere above the battery connectors. Eather that or the micro-USB connector, or even both at the same time.. The cable has turned yellow just under the connector so I don't know if it could be the charget that messed it up. This started before I even flashed a custom ROM.
Well I couldn't take it anymore and decided to downgrade my phone back to 4.4.4 which it came with. 9h on battery, Spotify was playing for 3h, played a little on Snes emulator, facebook, chrome, and I still jave 56% battery left. Seems to me that I was one of them who got the f*cked update for 5.0.1 and 5.1.1.. my phone is back to normal with speed, battery usage and heat. I'll let the battery drain completely today and see if it will turn off at 25-5% like it used to. The worst thing is that a game I used to play dosn't work on 4.4.4.. but it's still worth it!
Hi,
I have a Note 4 SM-N910C variant that is almost 3 years old.
Starting from 5 months ago the battery level would start dropping fast from 35% to 0% in like 2-3min after which the phone would turn off. If i took out the battery and insert it again, start the phone again it would show around 30% battery level. After a while it would start doing the same fast drops in battery level and so on.
I got a new battery, not OEM and now it doesnst do what i was facing above but it randomly turns off no matter if im doing something with heavy or no load on the device.
The turning off usually happens after the device goes bellow 50% battery level.
How can i test if all the components are ok other than the battery which seems to be faulty in my opinion.
I did order a new original OEM battery but it will take time to get to me.
I want to find out if the rest of the components are functioning without faults so i can decide whether i should get a new phone or not.
Please assist.
New battery
I know its not the same behavior, I have 2 note's. Mine is only a couple of months old while the one from my wife is build in 05/15. Her phone when we just received it would refuse to charge above 96%. Sure the phone would say 100% but as soon as you unplugged the charger it would drop straight to 96%. It did this on 3 different batteries, exactly the same behavior. All these batteries are OEM. When you plug it in it would go rapidly to 100%..
Anyway, I wiped the cache on that phone and since this it charges normally.
Been comparing the battery drain and both phones are using around 6 to 8% per night while on stby with wifi on.
Just try this, it may help you!
Thanks for the replies.
I did try wiping the cache and even did a factory reset.
I rooted the phone 2 days ago to try and recalibrate the battery but i didn't help.
I think the situation isn't degrading cause from today the phone is constantly hot and the cpu is running at around 48 celsius with 7-8% load.
I'll see what happens when the new battery arrives, maybe the phone is heating up cause of this maybe not. It's even eating the battery from 100% to 0 in 2h with no real load on the phone.
Do you guys think a benchmark program will force it to thermal shutdown if this is the issue.
I'm still trying to find out if only the battery is faulty or i have a dying phone.
To me you have 2 problems...a faulty battery and a (new) software problem on your phone.
Constant being warm with a cpu load tells me something on your phone is running all the time consuming your battery and causing your phone to heat up, unless it behaved the same before the factory reset and rooting?
You are rooted so try Wakelock detector for root to see which app (if any) is causing your phone to behave like this.
I will try wakelock to do its thing during the time i sleep. But if that doesnt help ill try a custom rom. Im not gonna factory restore and go back to stock rom. Gonna move away from that and see what happens.
