I meant to post the other day about a possible bug causing some bad battery life. My battery at first want great at all. So I decided to drain the battery and charge fresh. At 4% I cut the phone off and plugged in. At 25%I turned the phone on but when it booted it said 51%even though I just looked at it saying 25%. I continued to charge to 100% and used the phone with not so good results.on top of this I had the (nlpcollectorwakelock)issue. So I reset the phone let the battery drain to 5%and turned off the phone and let it chargeto 100% while off. Ever since I have got over 5hours screen on time a opposed to the 3before. Just something for desperate users to try before giving up

This morning after I got ready I took my phone off the charger (it had been charging all night and was at 100%) and walked upstairs. About 10 minutes later I turned on the phone and it was at 67% and going down. I had flashed a new rom yesterday and as quick as I could I did during the drain I did a NAND restore. Could this have been actual battery drain or is there something wrong with my phone/stats. Could my phone have stopped charging at 50% and then just said it was 100%? What should I do? Is there anyway to avoid this from happening again?! I cant go to work with a battery at 50%! lol
-.- Searching is your friend.
The Evo has never trickle charged properly. Trickle charging is when you hit 100% battery while charging and the phone will continue to keep the battery charging and maintain this 100%. So 100% > 99% > 100%.
The problem is the Evo doesn't do this. Once it hits 100%, it switches to battery. It will run off the battery till it hits about 90% and then charge again. Some even say it will NEVER charge again after it hits 100%. So when you unplug it in the morning, you end up dropping extremely fast from 100% to 90%.
There are kernels in the development section that fix this issue but there are people who say it will break your phone or burn your battery out faster over time. When trickle charging, your phone will get hot as its constantly draining and charging. That can lead to a burned out battery as time goes on or a damaged phone. I personally have three batteries. I still tried to use this and noticed a drastic improvement but my phone was also pretty warm when I picked it up in the morning. Its up to you.
Also you might want to see if you have your 4G radio on. That is probably the only thing I can think of that would drain it that fast. Either that or your GPS is on and theres an app running thats using the GPS receiver.
i'd say a 30% drain in 10 minutes is unnatural. it wouldnt be myns rls4 that you flashed, would it? this is experianced by some as a "first day side effect". just fully drain and fully charge the battery a few times and you will be fine.
It could be that it just needs a couple drains and I don't want to quickly point the finger at an app that you are using. A lot of times if I actually charge my phone it will be on 92% when I wake up. 67% is a stretch unless that was 10 minutes of a game or YouTube..but still. Drain the battery a few times and see what happens.
i was thinking maybe its some kind of battery stats problem? Could that have caused it?
after talking to lg and rogers i found a way to fix my battery bug or what ever it was........
Issue: weak battery-very bad battery life-needed to charge twice a day on normal usage. Lg and rogers both said its a hardware issue and need to be replaced......(IT WASNT)
Solution few easy steps should fix it:
1. Let your battery die to 0%. It drives down by 2%. Turn it on, it will let you turn it back on and shots automaticly back down. do it a few times till it shows0%!!
2. Plug it into your charger and let it charge to 100%.
right now its 2 pm i started using the phone at 9 am haevy!! besides that is my s3 that i used half as much today. Battery life on the optimus G is 60% and on the S3 55%. Battery life of the LG seem to went to normal. they claim its 40% better then on the s3. im trying tomorow on eco mode see if there is a difference.
PS: sorry for my english im italian live in canada and grew up in germany haha
I'm not so sure this is a good thing to do. I've read that you should never allow a Li-Po battery to drain completely because it physically damages it.
Then again, it's hard to find credible information on the subject.
Edit: Wikipedia cites the following article which states that overdischarging will damage the battery: http://www.powerstream.com/li.htm

Damage is when you leave battery discharged for some time, short period = almost 0. Of course there is little damage by doing this but no more than frying your phone at 100% Sorry for my english..
Fixed mine tho my battery life is crazy long now

It calls the placebo effect.
Li-polymer batteries calibrated on factory and they absolutely dont like deep discharging.
By the way LG promised 800 cycles of charging before the battery will start dying. I think in case of full discharge, the amount of cycles will be greatly reduced.
I have provisioned my battery which means going from full charge to 0 three to 4 times when I first got it and I always get a full day with medium use now.

I'm wondering, if this provisioning is so helpful for a battery, why wouldn't they do it at the factory?
After reading your guys' posts I decided to do a bit of a test.. I ran my phone all the way down from 100 to 0.. phone turned off.
Then, I turned my phone on about 5 times which then would immediately shut off onve booted to the os.
Then, I turned the phone on and placed it in the recovery mode.. doing this ensured that the screen stayed on until the phone was indeed drained entirely.
Then I charged it up till 100% before I went to bed, turned airplane mode on, closed the screen and went to bed.
Wake up this morning and looked to see how much battery drain occurred during sleep.
After about 5 minutes of using my phone it dropped down to 97%.. only lost 3% overnight. I was very pleased to see this as it confirms in my case that the phone is able to go into deep sleep.
I've also noticed that my battery seems to be draining slower than before.. before I could surf the web for ten minutes over wifi and lose a full 10% of battery.. so far today I've been on the web, downloading email, messing with some apps for around an hour or so and I'm currently at 86%.. definite improvement I believe.
And FYI this is with eco mode off, screen at 50% brightness, no gps and sync on sparingly. This is also on the latest update (my phone is on bell)

I'd be really tempted to try this, but I've heard so much from so many credible sources that total drain on Li-ion is bad news. Conflicted

It's bad to constantly cycle it full to empty. A full cycle once in a while is fine and on some devices it's necessary to calibrate the battery. Additionally, it's not good to store the battery empty. There's no harm in letting it drain all the way occasionally although killing it then further killing it in recovery is probably overkill.

Indeed, I only did it in the hopes that it would help to recalibrate the battery.. I recently was forced to run a flash back to the original firmware using the kbz method.. I was able to bring back to stock but noticed afterward that my battery life did not seem anywhere near as good as it was prior.
It could be that the kbz I flashed to was the newest updated version and it just isn't as good with the battery life but I felt it was worth trying draining all the way to see if it would help.. it does seem to have helped a bit though my battery still shows that android system keeps awake for 4+hours which is odd..
Anyway, once in a while I don't see it being a big deal.
If anyone is going to attempt the things mentioned here, why not do us all a favor and post some actual numbers from Better Battery Stats (a before and after) for some real analysis.
I'm not implying that anyone is lying, but it is just too easy to perceive an improvement when that is what one is expecting.
The plural of anecdote is not data.

according to my experience, the original one is the best
My phone just started to do this about a week ago.
I tried reflashing, wiping cache/data, factory reset- nothing.
Whenever I charge, it will either charge significantly slow, or say charging but the percentage just goes down as if it wasn't even charging in the first place.
So I powered off for the entire night, (8-9 hours) and it will say fully charged. And I keep it connected to the charger but when I take a look at the phone again about 15 min later it reads 83% battery and charging.
I was really annoyed so I just left my phone on the charger again while I took a power nap (1-2 Hours) and after that I take a look and now it reads 68%.
The other day I saw it was fully charged so I took it off the charger and went on with my day. After, not even about 8 hours, it was already 10%.
It's like it only charges normally when the phone is shut off. Do I just need to replace the battery? Or is it something with the phone that drains the battery so quickly? I've already ordered a replacement extended battery off of Amazon just in case.
Most likely your battery. Go into battery stats and see whats apps are having high usage. Or download Gsam.

Im pretty sure its the battery now, the stats are normal and it doesn't seem like one process is hogging all the cpu. Can't wait for my extended battery next week, i cant last a week more with this annoying battery issue. Any suggestions for now?

Hi all,
Last week I was using my Note and the battery totally discharged. I plugged it in, let it charge overnight but the following day, I turned it on, started to play a game, 10 minutes later, I closed the game and noticed my battery had drained to about 65%. The battery depleted really quickly and when it got to 1%, it stayed on for ages and then finally died. I turned it back on again immediately and it showed it still had about 60% left. Again, it drained all the way to 0% so I turned it back on and it then showed 17%. I let deplete again and then the thing was properly dead. I charged it up and tried using a couple of battery calibration apps but it keeps happening. As an experiment, I left it playing a video from 100% and the thing died 2:38 hrs later. This isn't right. I've also had my micro sd card wipe and had issues with that since the drain.
Any similar experiences or possible fixes?
Thanks guys

I had this problem before and the solution is......FORGET ABOUT IT!
just use ur note normally....the cycle of charging and draining gonna fix it but dont let the battery drop that low again....15% is ur minimum limit
Use this code to give u the correct reading of the battery too *#0228#
Anyway of getting that menu up without dialling it in? I have the P600 so can't make calls due to no dialer app

So I updated my phone tonight and after it used 30% in an hour or so. All I was doing was using FB on it. Prior I played PAD for 15 minutes and it hardly used 5%. I've wiped cache, cleared app cache, and now I'm working on a full discharge from 100%. The battery is brand new and it was getting better life prior to the upgrade. So much for 3x better battery I guess?
After clearing caches I left it idle ofer night. It used 13% for 20 minutes of screen time. and then it used 3% idle over the 5 hours I slept. Still seems a bit high on usage for screen time but idle is great.
So I discharged it completely and now its losing power fast again. The battery was 100% unplugged it and turned it on and its 97%. So I turned it back off and checked it and its also showing 97%. Charge it back to 100%, turn it on, its on 100% but loses 1% in a second. Plugged it in while onand it took like 3 minutes to charge that last 1%/ No idea why. The battery is brand new and got 2 or 3 days on idle before, now it reports 20 hours. what happened to that 3x better battery? What else can I do to sync the battery properly? I also noticed 100% is not 100% until the phone tells me battery is charged.
Again this battery is brand new and my life with 5.1.1 was pretty good.
I've been having poor battery calibrations in EPH7, though my battery is still what came with the phone.
There are days I can get to about 5? left before the phone dies, and there are days it dies at 15?..
Already tried charging all the way till full while the phone was off, still the same. It's random, but I just generally expect the phone to turn off as I come close to 15?.

That sounds like a bad battery. I can get my phone to drain down to 0% before it dies, but the battery usage can be erratic.
After some testingm the first 5% (95-100%) does down fast but after that it can go a pretty good while. Not sure why. I left the screen on with max brightness, turned on NFC/wifi/bluetooth and just left tons of apps running and it took 4-5 hours to get the battery down to 20%. the life is in fact great just not properly synced. No root makes it more of a pain to calibrate.
So I charged the battery offline and it got to 100%. I switched it on and it shows 97%. What the hell has marshmallow done to my note?
last post. If I charge the phone formt he OS it reaches 100% seemingly properly and doesn't discharge quickly. Not sure what marshmallow screwed up.
I had the same issue with my battery draining quickly after the upgrade. I backed up all of my data and then performed a master rest of the phone and then went into recovery and cleared cache as well. Once it booted back up I reloaded all of my apps and reconfigured all my accounts and my battery acts normal once again. It was a pain in the ass to do all of that but it did work for me so hopefully it works for you too.
