Running MOAR 8.0, I am getting days of great battery life, then occasionally the battery dies within a few hours, dropping quickly. The strange thing is that the battery gets warm to the touch when fast drain occurs, but is cool under normal circumstances. I have three different batteries, and thought it might be a battery issue, but the same thing happens on any one of the three batteries. Anyone else experience this sudden fast drain?

My Fuze has started to exhibit some very odd battery life behavior. Over the past 10 days or so, I've noticed a pattern of extremely poor battery life every other day. I recharge my phone everyday overnight, but some days the "low battery message" appears only after a few hours. I'll reconnect to a charger to make it through the day and then recharge overnight as is my typical routine. The next day, the battery will last me all day and not drop below 50% before I reconnect the charger before going to bed.
Today the "low battery message" came on only after 4 hours of battery use in which I did not make a single phone call, text, e-mail, etc. Yesterday I used the phone heavier than normal and the battery was going strong well into 11:00 PM.
I'm not sure if this is a battery issue or a phone issue, but I'll be darned if I can figure out what the heck is going on. Any thoughts?
I bet its most likely that the phones battery isn't properly calibrated and is why it doesn't show correct battery drainage. I would just buy a new battery if i was you.
Or load up a new rom to your device which cause the battery to need to be re-calibrated and should drain rather quickly over the first days and then go back to normal.( Note- you should allow battery to drain low normally before a full charge again)
But if your battery is just at its end this is pretty much useless, so either try it at your own risk, or just buy another battery -> Really cheap on ebay from trusted sellers!
hey everyone,
does anyone know if there is an app out there that will log the percentage of your battery, what time that % occurred, and maybe even how time between readings (like x minutes past from 90% to 80%)?
i am having some drainage issues and don't know where it is coming from. spare parts isn't that useful. it's probably some of my widgets, but i am seeing some usual drain recently with very little usage from my phone.
thanks!

Try that app it seems to do what you want.
thanks. i will check this out. i have been having strange drain. one night, my phone my phone drained hard and was pretty warm for it doing nothing. another night, it would drain only a few percent.
That app will do just what you want.

Hello,
I've searching for like 2 months about problems with battery life and Lollipop with nexus 5. I understand the issues but since it was released, i never had much problems with it. I used to have 2h SOT for like 40% battery or so.
My daily routine allowed me to reach home with a bit more than 50% battery with 2h SOT more or less. (a lot of messaging on viber/whatsapp)
But something changed since 1 and half months ago. I can no longer do the same and it seems that i have a CONSTANT battery drain. I remember when i unplugged my phone i would reach my workplace (1:30h after unplug) i would have like 2-4% less battery depending on the usage. Currently when i get out of home the battery is already at like 92% or more depending on the usage. If i let the phone stay idle all the time, i usally get home with 30-40% battery now. I'm already thinking that my battery has gone bad. This started to happen from one day to another and i never let the battery stay too much below 30% usually, but nowadays it's impossible to predict the battery life since some days it seems to drain more than others.
I've used some apps to monitor the usage but i really don't understand much about it and can't seem to find a pattern. I've already did factory reset with all Lollipop versions and i remember doing a KK regression for some hours but the drain seemed like it was still there (can't use KK on my nexus 5 anyway, it feels weird after Lollipop experience ) but i didn't even fully charged the battery as i remember. Anyway if it would be an app, there should be some kind of logging in battery stats which doesn't, and i can't think about anything else.
I finally gave up and decided to ask help here, since i don't know what else to do. I'm actually leaning towards getting a nexus 6 but after reading about so many issues (screen/battery life/burn-in) i'm not sure what else i can do with my nexus 5.
If anyone can give me a hint i'd be very grateful
PS: already tried Cataclysm ROM and using currently ElementalX kernel. I notice a bit better battery life with ElementalX but i think the pictures speak for themselves.
Judging by that constant drain with very little shown awake time I'd install Better Battery Stats and check for kernel wakelocks. I had a similar situation with a wake lock from using a wireless charger that did not show in the regular battery stats.

i already installed it before, but currently don't have it installed. I have Wakelock Detector app i can post a screenshot if helps
Installed Better Battery Stats, i'll post results tomorrow (battery at 19% already).
As promised, there's still some battery left but i didn't even use the phone today mostly... in days like these i should be over 70% as usual or maybe close to 80% that i remember.
Can't seem to find the cause
bump i guess
will some full discharge cycles fix this ? iirc that can make things worse.
I feel your pain...when I was on Kitkat, I'd get to work running just Waze and Pandora and my battery life would be at 80%. Installed Lollipop 5.1 and now half way through my trip (15 minutes of use) the phone shuts down with a dead battery. Maybe it's just a coincidence that my battery decided to give up the ghost at the same time I install 5.1, but I find that very odd...the phone is only a 1.5 years old...lithium battery's tend to last 2+ years and even then they don't fall off a cliff in terms of capacity. At this point I think I'll buy a new battery and see what happens, LG OEM are about $25 on Amazon.
As probably many of you already know, there is a shutdown bug mostly affecting Nexus 6p but also other devices as well.
I've been using my Nexus 5 for 3 years until a week ago I got the Nexus 6p, and I had not noticed this issue. However, after having the shutdown a couple of times with the Nexus 6p, I decided to test with the Nexus 5, and I'm finding quite easy to reproduce the problem, what make me wonder why I hadn't read such complains about Nexus 5 before.
Just getting to 15% and spam the camera a little (around 7 photos), and it dies (battery drop 15 to 0). Tested with two Nexus 5.
How old are the batteries in the Nexus 5 phones you used for the test?
You aren't replicating the bug. The camera really does suck down battery life like you wouldn't believe. You are most likely genuinely draining the battery 15%. I've been on a Nougat ROM for a couple of months now and haven't had any sudden battery power off or anything of that nature. I can bring it down to 1% everytime before it dies.
Are you doing this on stock ROM or custom ROMs? What Android version?
everything stock, 6.0.1.
your theory would be ok if the battery remained on 0%. But after turn it on again, some times is indeed at 0%, but other times it's at 15%.
Also, according to that logic, if the device is at 100% and I take 10 photos, my battery should drain to 85%, right?...
It's not a theory. Batteries don't always drain at a linear rate. For example, going from 100% to 85% could take 1 hrs. While going from 15% to 0% could take only 20 mins. This will be made worse by an old or dying battery. When a battery is under load, you have what is called "battery sag." Let's say the battery is at 3.7v. When under heavy load, the voltage could drop to 3.5v or lower, aka: battery sag. When the load is removed, the voltage will jump back up, though not as high as it started because while under that load, it also drained some juice from the battery.
You are probably experiencing heavy battery sag while at 15%, enough to drop the battery voltage low enough for the phone to power off. The heavy load is removed (camera is no longer on), and voila, now the battery is no longer "dead." My first Android phone (Tmobile G1) wouldn't even allow the camera to open if the battery was at 15% or lower. Most likely because the heavy load and subsequent battery sag would cause the phone to power off almost immediately.
I have a lot of trouble with the battery on my S7. Shortly after updating to LOS 18.1, it started behaving very strangely. The battery degradation happened over a couple of weeks, so it rapidly got worse.
At the beginning it shut down at anywhere between 15 and 20 percent, most of the time with the 15% warning. It got worse over time, then at some point it switched to being stuck at 80+ percent for almost the whole day, draining very little battery and then it just went black in the evening, like if the battery was pulled out.
I started slow charging the battery, which made things a bit better again. Now the percentage seems to be somewhat accurate again, but battery is draining so fast, I have to charge it twice a day to keep it running. It even drains battery while off, like yesterday I turned it off at 35% and this morning I couldn't even turn it on. Sometimes it also jumps from 100% to 60% after a reboot.
I made a backup and tried resetting the system, which didn't work, same behaviour. I could try to go back to stock, but as it also drains battery while off, I'm not too confident that it will actually make a difference.
As I have another disassembled S7 still in my repair drawer, I could try to change the battery, but my glass is a bit shattered at the bottom of the touch screen, so I'm afraid I'll completely break it this way.
I don't think there is much I can actually do, but I wanted to ask you people for any advice.
Edit: I have successfully transplanted the battery from my other S7 and it works great again. No battery problems at all, so the culprit was a faulty battery.
