Note 5 Not Charging Above 83%?

Hey guys,
I only got my Note 5 a few weeks ago and I've had issues with charging being inconsistent (even when battery is less than 20%). However an issue popped up last night now that I hope is a fluke. I let the phone charge overnight, and when I woke up this morning the phone never charged past 83%! What the... I'm hoping that after I charge tonight it'll go past 83% but any ideas on what could be cause thing? This is a nice phone but it doesn't speak well of their Quality Control that all these issues pop up. I never had any issue with my Nexus 5 and that phone cost less than half of the MSRP on this phone!

this is a battery defect.. Take your Note5 to the samsung service centre.. Im sure this will get covered in your warranty..

Problems with T-Mobile GN4. Read more

I recently sold my phone and got my friends old Galaxy Note 4 (T-Mobile) and immediately started flashing TWRP and a custom rom on it. Now, I've noticed that something fishy was going on with the battery percentage because once it starts to go below between 30% - 20%, it'll immediately cut off and triggers a bootloop until the phone's battery drains. Sometimes when it shows me a low battery notification at 15%, it shoots to 11% right after. I don't get it, is it possibly the battery being defected or the phone itself cause I had a Black Note 4 (under the same network) and it NEVER had these kind of problems and was using the same exact roms (on the proper baseband and kernel). If anyone could explain why this is happening and could give me a solution, I would greatly appreciate it. Thanks

Defective Note 4?
Hello, my father has a note 4, it's 1 year old, and 6 months ago, we got a new battery from Amazon, and it dies at 14% exactly, and when you charge it. It boots up at 14%, but again when removed from charger, it dies at 14%. Not to sure what to do... Old battery does the same I'm pretty sure.

Battery Degrading?

Hi, Lately I've noticed my battery draining very fast. Like 50% in 4 hours. So I installed accubattery to further see why. After a while it states my battery capacity has dropped to 80%. I've been experiencing miserable battery backup ever since. Do I need to change my battery?

When did u buy it and how often do you charge it?

Hi, I am also experiencing bad battery life, I'm on OOS 5.0.6 without root (stock kernel). Last month I was still on Nougat OOS and battery was fine, so I would go ahead and guess oreo is eating a lot of battery, also you can try and switch to 2G network, I was on 4G and mobile signal was not good and drain was higher then when I switched to 2G.
See pictures for info
I tried oneplus page "repair phone" so they change my battery but no answer from them (send the request on 19.11.2018.)

I'm in the same boat. Bought mine somewhere in the first months of last year (January maybe?) and based on 35 charging sessions my battery is now on 79% of the original charge (2701 of 3400 mAh). I'm thinking of sending it to repair service and pay to get it replaced because the battery life is noticeably worse even with the NLOS ROM and MicroG.

My 3T will be 2 years old next month. I was facing serious battery issues so after searching a lot, I installed Accubattery and let it analyse my battery usage for a few days. I found out my battery had been degraded to around 77%( no wonder I had to charge my phone ATLEAST 3 to 4 times for a 24-hour endurance, iwas on stock oxygen oreo with franco kernel).
THis july, i got my battery replaced(June END for Rs800 INR) and now i am on OOS NOUGAT(way more BATTERY FRIENDLY and throttles less compared to crappy unoptimised OOS OREO we got).
Battery was fine and lasted more than i needed for PUBG MOBILE. but within a few months, BUT only after 5 months battery quality has degraded to 82% again!!!!

I bought my 3T in December 2016, lately I have been noticing a lot of battery drain (everything stock and latest OOS). I have to charge my phone at least 2-3 times a day. However, I have been streaming a lot of video (chromecast) and audio (bt earphones) so I am guessing that could be the culprit. Netflix on chromecast is especially hell for battery life.

Get your battery replaced from original service center

I would take the battery health % with a grain of salt. Batteries hardly every have their advertised full capacity, even straight from the factory. I remember a thread from a while back (older devices - it's been a few years) where an XDA'er tested multiple batteries (factory condition) from various OEM manufacturers, as well as reputable 3rd party batteries. Hardly any met the advertised capacity. Something like 80-95% is about as good as you can expect. Maybe folks on here have some more device specific, and/or more recent data. And obviously, if you took the readings when the phone was new; you'd have a good start point. But the reading now doesn't mean a whole lot. Could have only been 80-90% to begin with. And replacing the battery may be a waste of money and effort.

I bought it april 2017, So That's 20 months now. Usually I charge to full every morning and some at nights depending on my usage. Untill 2 Weeks ago I charged every 6 or 8 hours (while I had the battery drain, happened for about 2 Weeks ) . Last week i moved from open beta to stable and wiped everything. While it's not as critical as before, Phone holds charge Better when screen is off but I still have worse screen on times. Now I don't charge above 90%.

Does this mean that you were charging the phone every time till over 85% and in general you were leaving the device plugged to charger for many hours?
If this happened for long time, then for sure the battery has been degraded.

Note 9 - Worth Doing A Battery Replacement?

Hi There,
I've had my Note 9 since December 2018 and it has treated me very well. Still does all that I need to do, as fast as I need to do it.
One small problem - the battery life is fully shot. Having to charge multiple times a day. I tried a while back to see if Samsung would do this for me, but they suggested that I wouldn't get much of an improvement in battery life due to software updates etc. I assumed this was sales bs but have found mates to have battery replacements to make a difference.
Therefore - is it worth doing a battery replacement on this device? I get about 5 hours I think at the moment. I would be interested in your experience. Just to add, I've smashed the bank panel pretty badly (everything still works) so probably would want to replace this as well (as they are a fiver on ebay - again purely cosmetic).
Thoughts?

I did it 1 month ago. It's now waiting for the 3rd battery, been for 1 week in the shop. All the new ones ware manufactured in winter 2018 and were weaker than the 2900 mAh left in mine after 3 years, so no.

Fair aha thank you !

By the way, just got the new replacement. It's much better at 3600 mAh after one charge, and I could get around 6 hours of Revanced yesterday with 25% still left.

Interesting - and you have had success with it?

I'm just sitting here googling this very subject. My battery is still pretty good in normal usage, but struggled to get through a full day in a recent hospital stay (when, admittedly, I was using the phone much more than normal). Torn between a battery replacement, S23 Ultra in a few months, or stick it out for another year and hold out for the S24 Ultra. Note 9 is still perfect in every sense (I have the 512Gb version), it's just the battery life is starting to weaken. If, as you say, the genuine replacements are manufactured in 2018, I might just go for the third option and hold out for the S24.

I use AccuBattery for a long time. It estimates my 3 years old Note 9 battery is 74%. I go to service center and change battery. Now it's 100% after a few full charge. I feel significant improvement in battery usage, maybe 1-1.5 hours more on-screen time with same softwares, same usage.

Question Brand New 10 pro, defective battery?

So I just got a new 10 pro from OnePlus a few days ago. Idk if If the battery is suppose to be this bad or if it's my unit itself. I know battery apps aren't usually super accurate but AccuBattery reports the battery design capacity as 4040ma. It's suppose to be a 5000 ma battery right? I have it set up as half brightness, only cell data active, no wifi, no bt, no NFC, no location, nothing else is on. I hardly use it, literally, maybe read reddit for a little on my lunch breaks. After a 8hr shif it's down to 20% with less than an hour of screen on time, about 45 mins id say. Is this phone this bad with battery? Is it from sitting in storage at OnePlus?, or should I return this?
Just doesn't seem right to me. I had a brand new 7 pro since launch day and that lasted most of the day with location, bt, high brightness playing Pokemon go and had a degraded battery with only 3450ma out of 4000ma left...

Sounds very defective, id return it or claim warranty or something

Lol, AccuBattery probably didn't detect the capacity right. Adjust it manually, give it a few charges (up to 80% for the best results) and then you'll have an ESTIMATE battery health. As for the drain, you may have something running in the background. I'd check that with root and something like FKM to see which process could be responsible.

Thanks to both responses.
I adjusted the design capacity to 5k. Right now it says estimated capacity 2475ma, which with the way it doesn't last even an 8hr shift with almost no use seems right on the dot...
Il try the charging thing and see what the estimate is. But after a week I figured even with the design capacity being wrong that it would estimate it way higher. I know AccuBattery isn't the best way to measure things. Il give it a few days. I still have til next Saturday to return it.
I had a bad habit of charging my 7pro literally every time it dropped below 40% when I was at work every day, so that's probably why that battery degraded so much, and id plug it in when I was driving too. Trying not to ruin this one like that. But it's looking like a return is in order cause with a 1000ma bigger batter than my 7pro, it should last at least what that one did, only you would think being brand new, alot longer...

I'm stupid.. I think I forgot to check the setting for dual cell battery in settings. Now it says 4951/5000. That seems more like it. And weirdly enough it has lasted a lot longer today than yesterday. I restarted a few times this morning. I think you were right about a process draining an absurd amount of battery the last week I've been using it.
Hopefully this will resolve itself before my return period is up, cause other than battery life this phone is pretty awesome so far. It's sad to see not much development on here for it yet. I'm use to seeing so many roms and stuff coming from the 7 pro.
