Context:
My dear LG G4 started having some battery issues this summer: it would sometimes turn off at around 15%, usually if I tried using the camera app. It would turn back on, at <10%. Left idle, it would actually increase the battery %.
About 1 month ago (maybe a bit more), the problem started to increase: it would turn off at ~40% - but not always, rarely. Last week, this happened everytime. Sometimes it would turn on back with ~5%, sometimes with 30%. Anyway, weird behaviour.
So I decided to buy a new battery. Can't be sure it's 100% genuine, but reviews say it should be fine (looks 99% like the old one).
Hoping it would finally solve my issues, I put the new battery in the phone. 5% charged - well, it's new, ok, np -> charge it to 100% and then go out to lunch.
The drain was awful, in less than 30 minutes it was at 75% (moderate usage at most). When it hit 74% it turned off. Problem is, this won't even turn back on. Got back to the office, plugged in charger - battery still reported 74%, phone turned on. Disconnected the charger, 1 minute later, phone turns off.
It's like when it hits 74%, it stops working.
Any ideas? Phone is still in warranty for a month, but not sure if this kind of problem is covered.
It's also my second G4, first one was replaced due to bootloop in summer 2016.
Download Accubattery app from Play Store, for the old battery , check it's health, repeat for the new battery.
My 2.5 year old LG G4 still has bad battery life because you know the SD 808 heats up quickly specially on hot summers or while charging, the battery's no1 enemy would be heat! So with the help of the app , I found the battery health had depreciated to 69% of it's 3000 mAh (that is 2069 mAh ) If your battery is new , I think your battery health should be 90%-100% in the Accubattery app!
Buy a new battery its done

Hello,
I've read the threads about battery in the desire, BATT FIX with new kernels etc but can't really find a definite answer for my problem.
I bought my phone 18 months old and from the beginning it has shut down at about 20%. Tried the battery thing with charging, on/off, charing again etc, wiping battery stats etc but it doesn't seem to matter. So, I thought I'd just buy a new battery and be done with it.
The new battery arrived yesterday (actually, it's a used battery from customer returns but seller tells me it's been tested to be in mint condition). So this battery shows 3% when I first start up with it, "good, this seems to work" I think. But when at 75% the charger indicator (LED light) all of a sudden turns green and battery % jumps straight to 100%. I do the battery calibration trick with on/off charge and wipe battery stats. Stuck at 100% for some time as reported by others trying this "trick", have been using it all day and it shuts down at 25% even worse than the other battery...
The best voltages I've seen on this supposedly new battery is 4,144 and somewhere above 3.5 (nowhere near 3.2 and 4.2). What strikes me as odd is that I get very close to the same values with my old battery so I'm starting to think that maybee both battery are good but the phone reports way wrong values...is this possible?
Battery life with phone and data connection on, 1 gmail account but disabled backup feature (no GPS, BT etc) gives me -5% after 10 hours standby and I can use the phone for browising, light gaming for about 3 hours and 40 minutes before it dies (more or less constant usage at very low autobrightness levels and Turbo 3G enabled).
If someone has some insight into this it would be really helpful before I contact the eBay seller for this particular battery.
Regards, Olle
Same thing
My phone shuts down at 35% now... Is that a problem with the chipset or what? Only with Alex-V's calibrated kernels my phone shuts down at 0%, and sometimes it decalibrates too, but after calibration is Okay. I wonder if i need a new battery or my chipset has issues.
I bought G Pro day before yesterday. The device is amazing and i love it but i have got a small problem. First day i charged battery to 100% and i got a day usage with 25% of brightness set with screen on time for about a little less than 4 hours which is amazing. Yesterday i had to charge phone twice because the battery depleted within 2 hours on screen time and moderate usage like calls n text (no gaming). Today morning 80% power was left of second charge. I went to college and and did not use the phone much but battery got completely depleted within 1 hour of screen on time at 50% brightness. When i came home back i charged the phone to 100%, when i disconnected charger from phone the charge dropped immediately to 98%. After 3 mins it fell to 93% and now is depleting fast. there is no apps running in background or anything and no apps showing up in battery stats that may be depleting battery. Any solutions to this? can it be faulty battery? Plz Help!!!
Edited: viber or whatsapp was causing this battery drain. I rooted my phone n installed greenify. Hibernating all user apps fixed the battery drain. If anyone has battery drain issue may try this solution.
Hello,
I'm considering replacing my battery. But before i pay for my own battery i must consider very carefully (due to personal problems). In LSpeed and other optimizing apps, the battery health shows Good. Is there any more accuracy way to examine it before replacing?
Thanks in advance.
You can consider a battery as being bad when you see percentages dropping all of a sudden (2% or more at a time), when the phone turns off on an early percetange (for example turning off at 20%) or if the battery starts getting swollen (it becomes "fat" instead of being flat). What you can try is to calibrate it (by draining it to 0% and recharging it to 100% 3 times or so) in case of percentage drop or early turning off, but nothing you can do againts swollen batteries, except replacing them. I had all the above symptoms on my Zenfone 2 and the reason was because the battery was swollen so I sent it to the warranty and they replaced it. And despise the fact that my battery was defect, the health was still shown as Good in both the system and any application that I tried using. So the battery health isn't really reliable

After reboot it usually drains 0-1%. Flash a rom/nandroid restore/backup costs 2-5% in 600 sec. And if we still have warranty, does replacing the battery costs any extra fee?. In daily use, when i paying attention on it, it drains 1%, but when I use it without attention on percent, it drains 2% (sounds so unreal, isn't it?) in same amount of time

Well it sounds pretty good to me. Sounds like the battery life is normal. I've had my phone since last year and my battery was always draining 1% at each 2 hours on stand-by. A restart can take 0-1%, depending on your charge level, but it seems pretty normal to me as well. As for on-screen time... I get 3 hours on 3D games, 4 hours on 2D games (like RPGs for example) and if I browse, I'm getting around 5 hours. I have only Skype and Yahoo Mail connected as auto-sync apps, the google auto-sync is off, location is off, brightness is set at 1/4 and some Zenfone features like the LED notification are turned off. So basically I did all I could to keep the phone on minimum drain. Most people will report around same on-screen time. By the way, I'm using stock rom, Lollipop 5.0.1, didn't upgrade to Marshmallow because I encountered some freeze and sound distortion problems while playing games (and I game a lot).
Upgrading to Mashmallow takes about 10% of my battery, downgrading takes around the same. Wiping cache from recovery takes 4% or so (takes a couple of minutes only). And if the warranty is still valid, the battery replacement won't cost anything, at least mine didn't. Mine was swollen, lasted for like 2 hours during usage and turned off at 20-30%.
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.
Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?
My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.
My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?
I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.
I have experienced this too
Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.
With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.
Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.
Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
