Odd battery problems

Hello,
My N4's battery has been behaving really weird over the past days. My phone completely fails to predict the battery's current charge and it often would shut off at for example 40%. When I reboot it's at 0% charge and shuts down again. The battery at that point is 'completely' empty. Which means that even date and time have been reset!
You can see the sudden battery drop here:
Stats (after few minutes on charger):
The weird thing is, that although the screenshot says 4h runtime on battery, it was running more like 8 hours at that time.
The screen time is also calculated completely wrong. It should be more like 2 hours, but it says 43 minutes:
Besides that, it happens often, that I unplug it after a night of charging and while it says 100% while still plugged in, once I remove the cable it drops to ~90%, sometimes even lower.
This was today morning after a night of charging (same day as screenshots above). Mind, that I had to replug it to achieve 98%, after I first removed it before showering it was at 91%.
I'm running Franco Kernel and Mahdi ROM. Though the problem exists on other kernels and roms as well.
Should I revert to stock and completely whipe everything? The only thing I restored from Titanium Backup during Rom switches are user apps and wifi networks. So I wouldn't consider it dirty flashing, right?
I hope the battery itself isn't damaged, since I get a maximum of 2 hours OST, where a week ago I would get around 3,5h-4h..
Thanks for your input.
Edit: Forgot to say, that another problem is, when using the wall-charger, it would tell me after 20 minutes charging from 0% battery that it's at 100%, while after a reboot it again shows only 20-30%.

try using xposed disable battery critical shutdown to recalibrate the battery
if dosent work -> rma it.

Thanks. As it has shut down again after about 3h on battery (1h of usage) I've noticed a relatively big buldge on the back of the phone. I think the battery somehow popped
I have absolutely no idea how that happened. Will write to the LG support now.

Return To Manufacturer, looks like your battery is worn out. If your N4 is over a year old you'll need to buy a new battery.

Any recommendation for where to buy a new battery?

I have same problem bro
Your shutdown at 40% mine loses network at 40% and shut down at 30%

Help me understand my battery

Nexus 6p running 7.1.1 beta. Rooted, but running stock ROM and kernel. Only modifications are Pixel launcher and Google Assistant. Brightness at 10-15%. Wi-Fi is on while the screen is on only, but Bluetooth and mobile data are always off. Location services are set to battery saving. Screen timeout set to 30 seconds. Adaptive brightness and ambient display is off. I'm only getting 3hrs SOT, but standby time is great. Only watch one hour of YouTube altogether and use social media often. Is this good or is there something wrong with my battery? ?

Install a battery app like GSAM and you can see what is using it, or things that may be causing wake locks.

Tried that and wiped the cache partition. No luck. I'm pretty sure it's poor optimization on Nougat. Hopefully Google will fix it.

Even i was on stock Nougat for a long time...but i didnt face such issues yet. Infact i think Nougat optimizes better than Marshmallow. As battery backup has substantially increased...a bit.

Well it may also depend on ur battery life..not all phones work the same as they must .

I seriously thought that such a big battery and the optimization that I 've witnessed on many other Huawei devices would mean that I would get better battery life.... How to fix this people.... Help!

I get 4 hrs of SOT
Average use daily is checking e-mails - checking Facebook and Twitter - Youtube and Music streaming - no games.... Sometimes, it drains without even doing that and I barely pass a day without charging it.....
PS:
The Screen on time is inconsistent as it might be just 2 hrs or 3 hrs and it would be consumed completely!
Is there a ROM or an app or anything that can help me get better SOT?
Thanks and apologies for the message, I now know that it was unnecessary.

As I said earlier, and I can't stress it enough, install a better battery monitor such as GSAM. You can see exactly what is using your battery and what is causing wake locks. It is the best first step in trying to fix drain.

Make sure you let it run for a couple full cycles and you have to read it correctly. You can't get useful stats the minute you install it because it needs to run through full cycles while charging and unplugged, as it can only provide information for the time it's been installed. The longer you run it, the more accurate it is. Second, the App Usage stat is a percentage of the percentage of battery used. So if your battery is at 70% when you look at app usage and it says those things used 57% of the battery, that's 57% of the 30% used to that point.
You also need to look at the Held Awake stats because that will tell you what, if any, processes are keeping your phone awake and thus contributing to drain.
I have found that the system in Nougat does tend to use more battery than it did in MM. However, doze implementation is better and it deep sleeps more and does a better job of saving battery. In fact since Nougat, I've stopped using Greenify because it actually seemed to make my battery worse. Since I've been on Nougat I get well over a day on a charge with about 5-5:30 SoT. However, battery also comes down to what ROM and kernel you use and how much you do processor and screen intensive tasks. Music streaming doesn't tend to use much battery, but if you spend a lot of time web surfing, Youtube and games, you'll cook your battery no matter what. If you use the Facebook app, nothing you can do will help as it's a dreadful battery suck.

Here are the numbers provided by the GSam App
Are these numbers good or bad?
The average use gets me through the day but if I use it heavily, it would last 3hrs max.

Oneplus 5 is overcharging battery voltage?

Hello,
I noticed my oneplus 5 has battery voltages over 4.3v. I've tried with GSam battery monitor and other monitors and concerned that my cell voltage is at 4.335. My understanding is that the cell voltage should never exceed 4.2v or it can damage or stress the battery. Does anyone else see a similar voltage? Perhaps the internal battery voltage sensor is off? Or battery monitoring s/w needs update? Please advise, Thanks!

I have came across a website that suggests that the newest battery chemistry is at max 4.35 volts. Although I myself am curious if that's the case. OP5 using latest battery chemistry? >Oneplus does use a different charging technology, and I've heard that without dash charging it only draws 1.5 amps. Also, 4.35 volts is a few years old.>

It's OK. Need advise? Enjoy your new phone, stop looking for problems.

There is no problems at all. You and OP just have no knowledge about batteries and speculate about problems which doesn't exist. This is waste of time, look at spec sheet of battery: Nominal Voltage - 3,85V, Cut-off voltage - 4,40V. Case closed.

In what way is this remotely an issue?

I am assuming that it's lithium polymer graphene chemistry. Hobby King has been carrying that chemistry for awhile, under their Turnigy Graphene line, and guess what charge voltage it ends at.... 4.35 volts. The graphene content helps lower the internal resistance of the battery which in turn increases the cycle life. It also helps the battery take more current during charging which would make sense with Dash charging.

Who cares about life cycle anyway? Each of us swaps phones after 1-2 years and when i sell the phone it is not my business anymore how bad the battery is.

Need your experience

guys i was planning to get op6t 6 moths used ons i have seen battry reviews which is pretty over the top but since many of u have crossed 5 months so how's battry now? after pie n all ? m coming from vivo nex changing only for roms n mods

Mine still get the same as it did out of the box. I'm on OB10 with great battery life. I average 45-50 hours if I'm not on it all day I usually get 4-6 hour SOT and still have 15% or so at the end of the second day. But if I'm on it heavy all day I still get 4-5 hours SOT and not have to plug it in until I go to bed usually.
Pics are about 3 days old but for example..

To explain it better, your SOT says 6 hours from last full charge, and on your third picture it shows a charge from around 25% to 75% then you've discharged again to 7%. So the SOT was from the full charge and then and 50% charge in between. So that 6 hours of SOT was from about 118% of battery usage.
So yeah, that's good screen time.

Have you tried the Sky Dragon ASOP Rom? The battery life is amazing.

I charge once a day/night.
I normally get over 5 hours. Here are my stats right now.

Cool thanks for the info. I'm new to this A/B thing so I need to read up on it a little more and about doing the backups correctly because I've seen that is different also. But soon as I get time to sit down and play I'll be jumping into it!

When you do a backup it's just the current slot it backs up. As long as you've not got multiple users you'll be fine.

Plus I used fluid to download 1.6gb then x-cast to watch a film on my TV, which is quite a high usage app.

I've had the McLaren since December 2018 running stock. I've not noticed any decline in battery life since the phone was brand new. However, I do not rapid charge my phones in an effort to extend their battery life. The exception was when my Moto X was dying last year.
Typically at the end of the day, the McLaren has about 80% charge.
Regina in Knoxville

My phone is a work "tool". At the end of the day, unless someone calls, I rarely touch it after work. I can charge it on Friday night, and save for some streaming in the car on the weekend, maybe a phone call or two, by Sunday, it still has 20-30% left. During the day, I use it A LOT, for calls, text, web. Around 1500 minutes on the phone per month, but rarely do I exceed 70% usage.

Battery recommendations? Does it need to be the battery for my exact model?

I noticed on eBay batteries for the Note 4 list compatible models for each battery. Are batteries for all Note 4 variants interchangeable? Or do I need to get one for my specific model? My phone is the SM-N910V model.
I'm in Canada and not looking for one of those big batteries. Just the stock/oem battery.

Lol I wouldn't be able to trash a phone, it will come back and haunt me. I know you have an LG now but how was the battery and what customisations did you do to improve battery life?
I got a ravpower battery few days ago but need some help with tweaking kernel settings etc to improve battery life as it is not that good.
Tried these optimisers like FDE and LKT but no luck, haven't tested LKT properly though as an update for FDE came out that should've fixed the CPU/GPU turbo boost thing.
Also, I don't care about gaming like PUBG (although I like it :laugh: )
Thanks for your previous advice/help and now of course.

You know what I think it's doing 10x better without optimiser thing. 10% lost by browsing on xda for 40min. Might be speaking too early.
Definitely still interested in changing some things around to improve it so please hit me with the facts/guides/tutorials/walkthroughs??!

Of course that wasn't a true story. Hah. I would never toss my "baby".
I haven't played with it much since but I ended up getting the Ravpower for it. It was cheap and arrived promptly. I used Kernel Audiutor for it and it's set to whatever the default is.
I can say I have gotten at least 90 more mins of SOT and more than a week of standby. Maybe even more. I'll power it up sometime soon and check Battery Bot.

Screenshot of my standby time. My OST is only ten mins at this point tho since this is no longer my daily driver.

Wow I actually believed it, was gonna ask if you tossed it at the bottom of a pretty much empty bin or... but it's getting emptied so must be full unless you did it earlier haha. Because I was wondering about the damage that may have occurred if this actually happened (from throwing it in the bin and then truck). How the hell would you find your phone just laying on top of all the trash in the garbage truck?!?! Now it makes sense that that's not true. I am really dumb:cyclops:
OK now I got that out of my head are you saying that kernel auditor automatically configures some things without you adjusting anything in the app? Because I didn't know that. Also what you mean by Battery Bot?
I don't think it does that unless you picked a standard configured profile that kernel auditor gives you based on device or something (not someone else's log configuration file or whatever you call it)
But like I said I don't know my kernel stuff... take your time I'm in no rush after all all of this is free and out of kindness which is something I really appreciate from XDA (or even the internet in general (duh))

I can confidently say I will get between 4-5hr SOT compared to trash SOT before (min 2hr max 4hr suprisingly, probably less intensive use)
On average 4.5 hours at least

I joke around often. Battery Bot is a great battery tool. I put the widget for it on my home screen and check it now and again to see how much approximate SOT I have left, how long it's been on standby, etc.
