No idea where things went wrong for you. Just speculation.

You're a troll, and a really ineffective one. At least own it instead of twisting your own words and backpedaling.

This whole conversation is useless.
[Samsung Galaxy Note 9 Questions & Answers] automatikjack:
Interestingly enough samsung themselves seems to side with the 80-40 crowd more than against it. On the pure whim to look at warranty information for my note 8, I decided to go to the samsung plus app, then diagnostics tab, then battery (yes I know warranty info isnt there, got distracted) at the bottom of the page for battery optimization tools theres a link titled "Keep Your Smartphone Charged."

In that link it specifies to ideally "keep your battery above 50%" and "Repeatedly allowing the battery to drain fully may shorten its lifeand decrease its overall capacity "

Additionally, the author states to "take it off the charger at 80 to 90 percent capacity" and that "leaving it connected to the charger when the phone is connected may lower battery life, if you do it repeatedly"

My two sense is that batteries definitely do degrade over time and yes, protection is in place that stops batteries from slipping below the minimum acceptable working voltage (effective 0%) for a number of reasons including being increasingly dangerous to recharge heavily depleted lithium batteries. Fully charged, I'll admit I either don't recall or I don't understand what exactly is going on in there except for the explanation that it is stressing that battery, whatever that means. I can say this, is looking at any of the display model phones go through charging hell at 100% for their entire lives at least at Best Buy and seem to have a much easier time depleting or even one which swelled and pushed pushed its screen out.
[Samsung Galaxy Note 9 Questions & Answers] greg elmassian:
I read this whole thread, laughing at so much confusion. There are multiple things at work here, and there's a thread of truth in almost all the postings.

First the person who said you never discharge your battery to 0% or to 100% is dead right... the numbers you are given are not really true... but the engineers cannot educate the public that the charger cuts out at 90% and 15% (or whatever this design does)... people would ***** an moan forever because they were not "allowed" to use "all" the battery.

So, when someone goes to research battery capacity on a battery manufacturer's site, THEIR % of charge is not the % you see on the phone... so that is a fundamental mess.

LiIon batteries (these are actually LiPo) have a lifetime usually expressed in "full" charge/discharge cycles.

Basically you have an expectation of a certain number of watt-hours of the battery over it's life

It has been shown that if you do not discharge as fully, you will get more watt-hours over it's life

It's also been shown that overcharging will reduce life.

Every one of these items have been mentioned in this thread, but the groupings and interpretation have varied all over the place.

But how you use your phone affects what battery charging and discharging strategy you should use.

The hardest question to ask: is all of it worth it?

Depends

why shouldnt i charge to 100? i get a consistent 6 sot sometimes 7-8hr depending on brightness level that given day
[Samsung Galaxy Note 9 Questions & Answers] Zanr Zij:
My friend and I keep battery between 30-90 ( more balance than 40-80 ) + charge anytime we can or we want. Only 100% on somedays I need outside longer.

Result: battery health much better than others ( My S7 Edge, 6s Plus, iPhone 7 Plus, his S7 Edge, Note 8 )

AccuBattery or GSam help me notify @90% ( enough to reset battery stats )
[Samsung Galaxy Note 9 Questions & Answers] nuclearrage:
I used to think this stuff was silly, but with the note 9 battery life being so good, I thought I would give it a try. I kinda loosely go between 40 and 80. At first it seemed I was always charging, but after about 2 weeks or so, I noticed the battery felt like it was lasting longer. Now after a few months, 80 percent in the morning , ends up close to 35 to 40 at the very end of they day. I have actually kept a very accurate log, but I would swear that I get the same battery life, if not more doing 40/80 as I did when I would charge over night to 100. At this time the battery has settled down to lasting new all day and still staying between 80 and 40.

Just my experience...
[Samsung Galaxy Note 9 Questions & Answers] alher591:
battery life is great on this phone might as well try the 40-80 challenge. there is a higher chance of me getting to a charger in between that cycle.

crazy that I even spent time debating this topic but since I am a heavy user might as well try it out.

so far so good!!
[Samsung Galaxy Note 9 Questions & Answers] arvin2212:
When you keep the 80 - 40 limit, does that mean you can no longer use Android Auto or Samsung Dex? Since both of them would constantly charge your phone.

How to charge a phone to 80% and not 100% overnight?
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
Set an alarm in Accubattery Pro.
[Samsung Galaxy Note 9 Questions & Answers] KOLIOSIS:
AFAIK,such control requires root.

If rooted,try this app out:

https://play.google.com/store/apps/details?id=com.slash.batterychargelimit

If you're not rooted,I wouldn't worry about it very much,but,if it's still nagging @ you,buy a plug-in programmable timer & guess at the time required for the 80% cut-off.

Phone mfgs have limits baked-in,to avoid maxing out,it's just indicated @ 100% to keep people from freaking out,thinking their phone won't fully charge.

Ditto on the other end,the phone shuts down before getting fully depleted to absolute 0%.

The 80-40 mantra is an overabundance of caution,IMHO,not worth your time to fret over.

At most,use the OEM charger(s) & cables & if you wish,use a fan near the phone to keep it a bit cooler during the charging process.

Any more time spent on worrying about battery health is not needed & definitely not worth the investment of time/worry over it.

Think about it for a minute:

Would Samsung be so foolish to not take these measures into consideration for the battery & charging after the Note 7 fiasco?

That's the last thing they want & can afford to leave to chance.

Enjoy your phone & leave the worrying to the 80-40 OCD Cult,they're hopelessly stuck in old habits when all Android devices had battery life issues.
[Samsung Galaxy Note 9 Questions & Answers] alher591:
i wouldnt worry about it. im just doing the 40-80 when i can. If i know ill be away from a charger all day then ill charger to 100
[Samsung Galaxy Note 9 Questions & Answers] willhemmens:
I have a Flow written in Automate that turns off a smart plug, with the charger plugged in at 80% charge and will start charging again at 75%, completely configurable. PM if you want a copy.
[Samsung Galaxy Note 9 Questions & Answers] william-johnson:
if this 80 - 40 concept is indeed true, does this then mean that Dex users are disadvantaged from the start as DeX will charge and keep you device at 100% while in use. I

use Dex as my main work station for like 9 hours every day during which the device sits in the dock.... charged at 100% .. I doubt Samsung would not have taken this into consideration before rolling out the N9 and Dex. Just a thought.
[Samsung Galaxy Note 9 Questions & Answers] pizza_pablo:
I thought it is 80% - 20%.
[Samsung Galaxy Note 9 Questions & Answers] galaxys:
It is 20-80! Which I usually practice...
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
in Soviet Russia, you charge to 20%, 80% of the time.
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
In Kazakhstan its 40-80 ;)

For the poster that mentioned DeX and surely Samsung would have implemented a battery charging limiter or to that effect query. No, why should they? They warrant their battery for one or two years so they dont care.
[Samsung Galaxy Note 9 Questions & Answers] Virgo_Guy:
I've been intentionally charging from 1 to 100% and using till it discharges till 1% from the very first charge to see how the battery depletes and how the battery life is after every fw/OTA update!!

It's little early to say but I've not "experienced" any battery health degradation in the last four months for this ""poor"" charging pattern. I've used almost all Samsung flagships in the past and applied the same battery "testing" in many of them. Based on that, I've not seen battery health going down in several months no matter which way I charged in Note 8, S9+ and now in Note 9. As such , sticking to a logic of 20-80%, 15-70% or any such makes how much "sense" looks doubtful to me. Additionally, Samsung's claim of newer batteries(since note 8) retaining 95% of it's health even after 2 years fuelled me to charge "poorly".

However battery health was going down in 4,5,6 months in s7 edge and it's predecessors in my usage.

Ps: not very relevant to the thread , but the OP can bear it. ;)
[Samsung Galaxy Note 9 Questions & Answers] d0x360:
Myself, my child and wife all got pixel xl's on the same day. They all ran the same stock firmware.

I installed Ampere on my phone so it would notify me when the charging hit 84%.

After 2 years of owning the 3 phones i did a test after we upgraded a few weeks ago to note 9's. My phone which almost never was charged above 85% lasts 6 hours longer (average over 10 tests) while idle than the other 2.

When running youtube at 1080p via wifi it lasted an extra 2 hours.

So there is definitely benefit in how you treat your battery. There have been studies on the subject and they were definitive. Its not just in peoples heads.

So my note 9 will (almost) never go above 85% or below 20 which means my battery will last longer than theirs
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
jve been using :

https://play.google.com/store/apps/details?id=com.slash.batterychargelimit

and setting it to 88%.

so u set it and forget it.

been please with it.
[Samsung Galaxy Note 9 Questions & Answers] Virgo_Guy:
You aren't considering two factors here :

1. Samsung made official claims of newer batteries retaining health of 95% even after 2 years of usage (since note 8 days). You are talking about first gen pixel.

2. It doesn't look like Samsung has been allowing users to charge till 100%(full 4000 mAh) even when users charge till 100%, thus maintaining battery health.

How you are charging and discharging matters ,but how much it matters to Samsung latest flagships might be another story.
[Samsung Galaxy Note 9 Questions & Answers] d0x360:
Yes im testing with a pixel but the point is batteries.

Samsung makes lots of claims, that doesnt make them true. Its impossible to know if Samsung stops charging the battery before it hits its real capacity. Its also impossible to know if Samsung's method of monitoring charge level is 100% accurate. Samsung software isnt known for being...good.

There have been studies done on lithium batteries and no amount of tinkering by samsung ia going to change the basic laws of physics. They are using the same chemicals used in the studies.

Point being, and we can argue in circles for days... actual scientists have tested this very question extensively and they have determined optimal levels for charging. Whether you want to follow those guidelines or not is your choice but it doesnt invalidate their data which was collected over years of testing thousands of batteries and devices.

Plus it doesnt hurt to stop charging at 85% regardless of what you choose to believe. Generally that 1st 20% of battery drains faster than the remaining 80% because of physics. It will drain even if its not powering anything and that 1st 20% goes empirically

quicker
[Samsung Galaxy Note 9 Questions & Answers] Virgo_Guy:
None is trying to invalidate the battery science and chemistry. Get that .

Irrespective of how you charge including your very "careful charging pattern" will NOT stop the battery from depleting over time. But with the help of measures taken ,it can be slowed down which is what I greatly felt with the Note 8, S9+ and Note 9 that I USED without taking any "battery health saving" charge pattern. As such, taking "careful ways" to charge wouldn't have made much sense here in my usage.

Coming to Samsung software, unless you have a proof or legit links against Samsung for not implementing measures to save battery or prove them wrong against their official claim, it would be fine to assume with experience that Samsung is doing a great job at what they are claiming in terms of battery health.
[Samsung Galaxy Note 9 Questions & Answers] KOLIOSIS:
I'd dare say all mfgs take similar measures to ensure batteries don't get maxed-out on either end of the spectrum.

(Pretty sure they all have charging temperature safeguards built-in as well.)

They just don't use the "true" indicating percentages,especially on the full end,so people don't think they're getting short-changed with a lower capacity battery than advertised.

That's why I'm in agreement w/you,any further measures are likely not necessary.

Also not doubting people may be able to squeeze out a bit more/better battery service life,but,how many charging cycles/months/years before you actually see any measurable positive benefit?

Unless you have the min/max battery charging automated,the worry/trouble keeping up with it just doesn't seem like a worthwhile endeavor.

Now,I'm all for a mfg to step up their game & build-in the functionality of setting the min/max values,that would be cool,after all,the lure of Android is all about choices....
[Samsung Galaxy Note 9 Questions & Answers] darkbahamut:
It's not impossible.

The charge setup is in the kernel sources for everyone to read. We know exactly what they are charging the batteries to, and therefore we know they are undercharging them.

Coming from a Note 4 the non-removal battery was one of my biggest gripes about upgrading device because it's much harder to replace once it ages, but I'm quite pleased to see that Samsung are actually quite gentle on the battery. They'll still age of course, but it was a nice surprise to see they had made an effort to extend battery life. I'm planning to reduce the max charge voltage a little more still in my kernel to sacrifice a a bit more capacity for even better cycle life.
[Samsung Galaxy Note 9 Questions & Answers] d0x360:
I mispoke...kinda. i wasnt talking about software despite ny wording. I was talking about hardware and how it handles the information received. Not all charging circuits are created equally.

For the other posts..

You dont know if my not really that careful charging methods are doing no good. All im doing is unplugging at 85% which is...simple. Battery chemistry currently dictates (despite what phone companies do themselves) that these types of batteries have optimal life when charged to 85%...again its physics. You can find the study's on google pretty easily. Just because you didnt notice a difference doesnt mean its not there and as time goes on it gets worse so why not do a simple thing to help?

My samsung experience is limited to the Galaxy Nexus which destroyed battery longevity in both the ones we owned. By the time 24 months rolled around they were lasting about half as long as they originally did and thats with one staying stock and the other having a custom kernel and rom. Then i had a note 7 and that didnt go well.

As far as their software the only proof i have is the galaxy app store reviews and my experiences using what comes on their phones. The launcher us garbage, so is Bixby, their voice recognition, "optimization" service, messaging app, dialer and contacts apps and pretty much every other app they wont let you remove or disable.

Even the interesting functions like the edge light has too few options to be useful and they stuck an LED in the phone with no built in way to control its colors and its apps dont let you pick them either. Yes i know thats the norm but it doesnt make it good or ok.

I like my note 9 i just wish it wasnt so bloated and im not paying for the bloat removal app that keeps vanishing and making you buy it again. Plus everything that can be tweaked via 3rd party apps today probably wont work when they update to android 9... like the LED notification apps and since i cant root it i will probably wish i stayed on android 8.1 despite enjoying 9 on my pixel xl quite a bit.

Their support is also garbage. Getting a human is absurdly difficult. The samsung + app that lets you contact support doesnt seem to work well considering i asked a question and its been "waiting for a response" for 3 weeks.

Also now that i think of it some of the preloaded apps dont work at all. An example is the 24 hour file share app. It works on the note 8 but not the 9 despite coming installed. If you upload a file and give someone the link it always says expired on the 9.

This has gotten way off topic and i apologize for that but i was asked for "proof" that they make poor software and its impossible to "prove" that aside from.sharing my experience and telling you to check the galaxy app stores reviews. Every samsung app is reviewed badly and for good reason.
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
Lol at the battery disabling app that vanishes and comes back with a new name that one has to buy again. So true. I'm done with them also.
[Samsung Galaxy Note 9 Questions & Answers] michelino159:
We do not deny the laws of physics but in the new batteries from Samsung, starting with S8 there is a paradox. What I mean is that the 40-80% work it deteriorates faster. How can, I do not know. When I bought Note8 from the first day for 5 months I loaded 35-80% and PhoneInfo showed me 92% health of the battery.PhoneInfo was reading the system file fg_fullcapnow, which is now blocked on Note9 and you can not read it without root.The others who uploaded the normal Note8 phone, 20-100%, had 98% health, and those who loaded it only for fast charge had 97%. There were people after 5 months who health are 100% only charged the wireless ,no fast.. So you can draw a conclusion. Well, the system files do not really appreciate the health of a battery, but a dose of truth exists.

I think there is a limitation of loading, and the materials used are qualitative for new generation Samsung batteries. This limitation does not fully charge the battery but only 3753 mAh, the rest being a buffer zone.
[Samsung Galaxy Note 9 Questions & Answers] michelino159:
Look at these screens. From the first day until today it only loads 3753mAh. In so many months something was lost, but nothing was lost, so it's much more than 3753mAh.
[Samsung Galaxy Note 9 Questions & Answers] michelino159:
When you load 100% battery capacity of 4000mAh then there is a voltage in it's loading that damages. When the charging at 3753mAh is lit, that voltage is lost and the losses are minimal over time. Then what's the point to come with a limitation of your 40-80% over Samsung's limitations?

My opinion that those 250mAh due to the limitation you will lost in 2 years because of the normal load 25-100%. I really am curious if the 3753mAh will drop before 2 years.
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
I thought the 3753 figure was erroneous. Or do you think this is true full charge value? I think the only way to get to the bottom of this for someone to fully charge and remove the battery and check the cell bypassing any onboard controller circuits etc to get the value.
[Samsung Galaxy Note 9 Questions & Answers] michelino159:
Exactly!

3753mAh is the limit value imposed by Samsung at full load voltage.

---------- Post added at 01:11 PM ---------- Previous post was at 01:09 PM ----------

I think it's also possible through root by changing the kernel load parameters.

How would you unlock Huawei phones bootloader after they have stopped giving unlock keys?

Is there any alternative method beyond requesting them.
[Android Q&A, Help & Troubleshooting] Raiz:
I don't think there's an alternative method , but you can always search through the Huawei Forums to find another method.
[Android Q&A, Help & Troubleshooting] adnaanhitman:
There is an alternative. It isn't a free service though, it uses PayPal & it has successfully provided many Huawei users with their device Bootloader unlock codes. It's called DC-Unlocker. It provides much more than bootloader unlock codes. It works with a credit-system. Whatever you need requires a certain amount of credits & you purchase them from their website. I am unable to use them because of PayPal issues in my country & incompatibility with my bank.

Not sure how many credits, or how much it costs to have your bootloader unlock code sent to you. That you can get on their website along with all the info you need.

Hope this info helps.

Good luck!

I KNOW I'M ASKING A LOT FROM YOU GUYS, BUT I CAN'T RISK LOOSING DATA AS THIS IS MY MAIN DEVICE.

I'm presently on PR1 rom which was ported to our devices by [MENTION=5293805]GtrCraft[/MENTION] which is crazy stable. Any minor bugs that exist can be overcome easily by a simple reboot!!

I really wanted to install this as this room is based on pr2.

Pls also tell if this rom has inbuilt pixel launcher integration for recents. Lack of it can be a deal breaker as this was the only reason I reverted from arrow rom. I need all the Google pixel features as I think I'm addicted to those.

THANKS AND SORRY FOR TROUBLING YOU GUYS!!!
[Moto G5 Plus Questions & Answers] jDally987:
Ok...you know you can just do a nandroid backup of your current ROM and be literally ironclad safe if anything goes wrong?

Just hit "Backup" in TWRP and backup System, System Image, Data (excl. storage), Cache, Boot, (and EFS and Persist just to be safe).

Then flash PR2 to your heart's content and test it out yourself. If it ****s up in any way, reboots randomly, texts your ex, begins running missile launch codes or anything else you don't like......go reboot back to TWRP, "Restore", and choose your backup.

[Moto G5 Plus Questions & Answers] jDally987:
For the roms like Arrow Pie, you have to enable the pie recents (labled "swipe up from home button") somewhere in the settings. I think it's at the very bottom in System or something.

For the space issue though, if you don't have an SD card I'd just back everything up to your computer via USB and then backup. Then you can pull the backup off (to your computer) and have that ready in case anything catastrophic happens.
