How are we supposed to charge the phone? Do I let it drain all the way to zero the first few times, to "calibrate it" and then try to keep it between 80 and 30 percent?

I've heard getting to go all the way to zero is really bad? It also causes the battery to heat up a lot when it's being recharged?

I've gone through one charge cycle so far. And charged it at 11%. I wanted to let it go to 1%, but chose not to.

Someone help me with this. What is the best way to treat the battery when you first get it?
[Samsung Galaxy S21 Ultra] mzsquared:
I just charge it when it goes low and I have time to plug it in. I don't have a specific preferences, whether @ 30, 20 or 15% regardless. I don't think there are any special requirements for that, though I see ppl create their own beliefs and the'd swear to it as "the most optimal charging routine".
[Samsung Galaxy S21 Ultra] eyeatoma:
Thanks man!
[Samsung Galaxy S21 Ultra] eyeatoma:
Any other opinions would be greatly appreciated.
[Samsung Galaxy S21 Ultra] mankvl:
At this point in battery tech i believe it doesn't matter. But a lot of ppl and articles suggest to keep phone in 20-80% range.
[Samsung Galaxy S21 Ultra] dscline:
I did charge it up to 100% when new, then let it get down to about 25%, but generally I try to keep my phones as close to 50 as possible, with shorter frequent charges. I have wireless chargers on my desk at work and home, so it's simple to just set them there occasionally as needed. I have fast wireless charging turned off to keep heat down, and an app on the phone with an alarm that goes off when the charge hits 75%, but I'll often take it off closer to 60 if it's convenient. I'll put it back on around 40%. I'll charge it up further if I'm going to be out for a long day, and will plug it in if I need a faster charge. https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
[Samsung Galaxy S21 Ultra] xnostra:
i use accubattery and use its alarm function to alarm me by default 80% charged
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
NO. NO. It's 30-80%.

Better yet: 37-65%. Or, if you want to be dangerous: 35-65%.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
I keep it around 40% at home.

I even have a 1W charger LOL. It can do 40 to 100% in 8 hours! Perfect for sleep.
[Samsung Galaxy S21 Ultra] nightoooo:
or better to not have a smart phone at all if people get so picky!!

Guys, just do as the phone tells you, when it reaches 15% .. put it on charger until 100%. It gonna last at least 1-1,5 year before you notice the degradation of the battery.
[Samsung Galaxy S21 Ultra] sammiev:
Using the same method as @nightoooo above.

I'm only on my 2nd phone, first was $99.00 phone that lasted 3 years and now over 2 years into my Samsung A20 with no noticeable change in battery life.
[Samsung Galaxy S21 Ultra] neilth:
I use the AccuBattery app with IFTTT and a smart plug for the charger. I set AccuBattery to create a notification when battery charge reaches 76%. This creates a notification saying to disconnect the charger once a 76% charge is reached. The Android device service in the IFTTT app sees this notification and then IFTTT sends an order to the smart plug’s app telling it to turn off the smart plug. I have been using this configyration for several years and it works like a charm. My previous phone, a Pixel 2 XL, has never been charged to 100% and after 2 1/2 years of use the battery is still working fine.
[Samsung Galaxy S21 Ultra] blackhawk:
My 10+ lasted 1.5 years of heavy usage.

It then failed. Don't delude yourself as to the longevity of Li's. You may do better or worse.

Batteries are cheap and relatively easy to replace. A Li failure can total the phone.

Regardless how long it last once it's capacity is less than 80% of it new capacity it's time to replace it.

Degraded Li's are more likely to fail.

Signs of failure; sharp drop in capacity in a short amount of time, erratic fast charging, case bulging ie battery swelling which can damage the display or worse.

There's no reason to discharge below 20% except to calibrate. Charging beyond 90% takes too long and is stressful on the battery.

Li's prefer frequent midrange power cycling. This isn't a NicCad or a lead acid so forget those rules. 40-70% is near ideal.

Charging start temp should be 82°F or above.

NEVER attempt to charge one that is 40°F or less.

Avoid letting charge temperature go much over 100°F.

Regardless of the charger or time, it will stop charging at 100%... if you insist.

I use midrange power cyvling with a fast charger because it's quick and convenient, more bang for the buck. If I replace this battery next month I really don't care as at this point it's just routine maintenance to me.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Here we go again. No, they're not easy to replace for the average Joe.
[Samsung Galaxy S21 Ultra] blackhawk:
Don't make me laugh too hard... I was once like you. Have someone do it for you. I got mine done for $50 and learned.

There's not many phones that are harder than the 10+ to replace the battery.

And it's a cake walk🤗

Replacing the LCD screens on my 5D and MK3 were harder only because you need to line up the one time use wrap around rubber skin perfectly the first time when reassembling.

Still intimidated?🤣
[Samsung Galaxy S21 Ultra] enigmaamit:
It's difficult to buy genuine batteries in many countries. Most people would rather have an original battery from the manufacturer last longer than have it degrade and replace it with something from a questionable source. Again, the discussion here is how to minimise battery degradation and prolong it's life rather than learn how to replace a battery.

Analogy: If someone asks a question like "How should I drive my car so that the engine doesn't wear out fast and lasts longer?" To suggest that you should not cultivate good driving habits, and abuse the engine, then replace it in a year isn't going to help. This kind of approach may work for someone who like to drift and drag-race or race but not for the average person who likes to take good care of his/her stuff.

Everyone knows that when something fails and stops working, it needs to be replaced. But that isn't what we are discussing here. We'd like to prolong it's life and prevent premature failure.
[Samsung Galaxy S21 Ultra] neilth:
About a month ago I went on the Samsung Members app and put in a request that they add the ability to terminate charging at a user selectable charge level in their Bixby Routines. I then called their tech support 800 number provided in the Samsung Members app and verbally made the same request. The person I spoke with thought it was a great idea. I have never heard back from Samsung about them implementing such a feature though. It would possibly help if they received many more similar requests. If it was a popular request they would be more likely to add it the their software.
[Samsung Galaxy S21 Ultra] blackhawk:
The worst thing you can do is not change out a degraded Li. You risk destroying the whole phone. Excuses are like...

You want to ration your cell usage?

Go for it.

I could add a whole list of things to prolong the battery life but it's not worth it.

The battery is flimsy, cost about $14 and was born to die. Parts are readily available especially a year after the release.

Even an amateur can change one out in less then an hour. Rear covers are about $16 but you won't break it if you don't rush it. But the details matter and you can't force parts or over torque screws, less is better. If you're really nervous practice on some scrape phones which aren't too hard to come by.

It's a lot easier than rotating a set of tires or changing a set of spark plugs.

Right off the top of my head, what you need:

Heat gun, fine tip tweezers (for the micro connectors), the proper micro drivers* (sold in kits just for this), plastic picks, sunction cup (optional), anhydrous isopropyl alcohol with a needle applicator syringe or bottle, OEM adhesive seal for the rear cover and the battery. About $35-50:less the heat gun. Optical aids are optional. Keep room humidity greater than 50%.

Sounds intimidating but it's not. Learn by doing.

*use a magnet to magnetize them if they're not already.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
When I first get the phone, I charge it to 100% and that's it.

After that, keep it in the 30-80% range and your future self will thank you.
[Samsung Galaxy S21 Ultra] felloffthetruck:
Charging to 100% is a no no?

I've been charging to 100% but better change my habits.
[Samsung Galaxy S21 Ultra] ione2380:
100% isn't really 100% on this phone. You can charge full all the time, don't worry about it. Just don't let it discharge to low. I charge 40 - 100 always.
[Samsung Galaxy S21 Ultra] M@nu1313:
I know someone who's working with Samsung's service centres, they check the total full charge cycles to identify the battery health. Usually when you go for a display replacement or any other sorts of warranty service they'll replace the battery free of cost if the recharge cycles have not past their set limit.
[Samsung Galaxy S21 Ultra] deakodude:
I just plug mine in when it needs a charge.
[Samsung Galaxy S21 Ultra] blackhawk:
Low discharges >20% stress the battery needlessly. High voltage plus high temperature is the most damaging.

My high cut off is 70-83% usually. After 80% fast charging has cut off and charging slows even more after 90%.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
DO NOT KEEP YOUR PHONE'S BATTERY >80% AND <30% for too long or on a regular basis.

This is why you see iPhones lasting 6 years easily -- they avoid >80%.

Stupid Samsung can't give us a bypass-charging feature.

Can't wait to switch to iPhone in a few years after these losers can't get this **** together.
[Samsung Galaxy S21 Ultra] blackhawk:
"But Debbie, pastels?"

iphone is no bowl of cherries unless you include the sweat shop labor mills🤣

Changing the battery isn't a big deal once you grasp the concepts needed. At under $20 a pop, it's chump change. A small price to pay for the most customizable stock phone on the planet.

With iphone you pay out the a$$ for internal memory and no irreplaceable SD card slot. Worse their junk is made by the CCP.

I choose a phone made in free countries.

S Korea, Vietnam and India are our allies.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Apple is 'Murica and 'Murica is Apple!
[Samsung Galaxy S21 Ultra] blackhawk:
It reeks of the CCP laborers sweat.

What a mundane and boring platform it is... a pastel of what could have been bright and vibrant. Great for the tech challenged.

Rise to the top or get lost in the mix.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Where do Samsung and others make their tech? I'm guessing sweat shops in China and other places.

More importantly, the problem with not having an iPhone in America these days is that the "tech-challenged" iPhoners outnumber the rest of us. So, we have to adapt to them and their ecosystem, not the other way around.

I'm more inclined to blame Google/Android and Microsoft for their failures rather than Apple for its success.

iOS 15 will have built-in network activity tracking that will let us see what domains an app tried to connect to over the course of a certain time period.

Android better step things up.
[Samsung Galaxy S21 Ultra] ione2380:
I have an HTC u11 that is 3.5 years old. That thing has been charged daily to full and completely discharged and used while it was charging and battery still holds an entire day. Iphone batteries are crap. My friends with Iphone 6s and 7 charge their icrap twice a day and their phones shut down when is cold outside. Iphones don't avoid going past 80%, they just slow down charging from 80 to 100, after they learn your charging habits and that rarely works. Samsung has much better quality batteries than apple.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
We need more clarity on whether these OEMs over-provision or not.

And, charging multiple times per day is not a sign of battery weakness.

Random shutdowns or shutdowns from increased workload are signs of battery weakness. How well does Android manage that? Poorly.
[Samsung Galaxy S21 Ultra] blackhawk:
Damn, get your twisted facts straight.

S Korea, Vietnam, India, Taiwan, Indonesia and Brazil is where Samsung are manufactured or sources.

China is their major economic and military threat as well.

Samsung wisely got out of China most riki tic.

Where Are Samsung Phones Made?

Samsung is a South Korean company, but where are its myriad devices manufactured?

Your Apple is rotten to the core🤣
[Samsung Galaxy S21 Ultra] proxybox:
This is really cool. I use the Battery Charge Limit app on my Motorola but it requires root. My new S21+ can't be rooted so I found your post. Can you share more detailed info on how to set this up? I just don't understand how to integrate IFTTT with the AccuBattery app. Much appreciated.
[Samsung Galaxy S21 Ultra] annson08:
I charge my phone whenever I can, I have a charging station on my office desk, my gaming desk, and my bedside. With this, I can use all features of my phone without having worry about my battery juice.

On my rooted Oneplus 6 with Android 10 and build number lineage_enchilada-userdebug 10 QQ3A.200805.001 9a112f9dd6

the app "10341" with a black android symbol uses a lot of battery.

Does anyone know how I can find out what this is?
[General Topics] schoebi_zh:
Now it changed the name to -5 and uses not that much battery. Weird.View attachment 5205823
[General Topics] blackhawk:
That's UID number. Maybe someone here recognizes the icon, I don't.

A 3rd party apk?

Go to Playstore, download Karma Firewall and block it. Karma Firewall is VNP firewall that uses very little battery, freeware and ad free.

See if firewall blocking it reduces battery consumption further.
[General Topics] schoebi_zh:
It doesn't appear in the app list or in Karma, it changed the name to -5 the next day and didn't appear after four days anymore. Very weird.
[General Topics] blackhawk:
Could be a virus or trojan. Any more erratic behavior I would reload.

At this point I would have reloaded if I couldn't ID it.

I would at the very least scan with Malwarebytes.

The trojan preloaders are out there and pretty much download themselves.

Always keep a close eye on the download folder.

If you're willing to pay the four euros, how would you unlock the bootloader?
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] -Alf-:
You have to downgrade to A7 Nougat.

Use HiSuite, try it with chinese version:

Link

or

Link

If the rollback option is not available with your HiSuite ("switch to the older version" or "Earlier version"), you must downgrade to the lower Pie/Oreo build version number doing the dload method (flashing Service ROM ) and try again with HiSuite. (Dload process will erase your data!)

What is your build number? (Settings > About phone)
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] Crescent2135:
9.1.0.146 (C00E135R2P7). I haven't tried doing the HiSuite thing yet.
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] Crescent2135:
I tried using the first HiSuite link and while I can downgrade versions, it's only to Android 8.

I guess, I might need to do this then?
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] -Alf-:
Full build and model please, e.g. AL00, AL10 etc.,

Yes, ane then downgrade to A7, if it's possible
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] Crescent2135:
It's the BND-AL10.
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] -Alf-:
Okay, supported model , now you can try to download to A7 using the same method
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] Crescent2135:
Pardon, but what method?
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] -Alf-:
HiSuite
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] Crescent2135:
I've downgraded it to Emui 8. HiSuite doesn't seem to let me downgrade it any further than that though, instead pushing for me to upgrade again.
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] -Alf-:
Your current build number?
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] Crescent2135:
BND-AL10 8.0.0.368(C00)
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] -Alf-:
Okay, download 8.0.0.352 service ROM

Link

Unpack, find dload folder in "Software", copy it to the SD card (without unpacking it! ).

Turn of the phone, press and hold Power and both Volume buttons.

- initial settings and try HiSuite again.
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] Crescent2135:
I managed to downgrade it to 8.0.0.352, but HiSuite's doesn't give me an option to downgrade from it. It just tells me that it's the latest version available.
[Honor 7X  ROMs, Kernels, Recoveries, & Other Devel] kurangan:
I tried,

HiSuite_9.1.0.305 (from the Link)

HiSuite_10.0.0.510_OVE

HiSuite_10.0.1.100 (from the Link)

HiSuite_11.0.0.650_OVE versions,

There is no such options related to downgrade/switch to older version.

[Oukitel (All phone models)] calfax:
I bought the Oukitel WP10 as my replacement for my previous phone, an AGM X2, which is was getting on in age. Reasons for purchase: 5g, ruggedized phone, giant battery, POGO pins on the backside for connecting ???

The phone, physically, is fine, It's giant brick with a big battery, a decent camera and all the usual sensors are there. It as the potential to be a really neat phone....and then you boot it up. Something was and is.....not right. The developers lobotomized their rom. Why? Who knows. Will they fix it? {edit: they did sorta}. The app drawer is missing so the phone dumps all your apps out on the home pages. 3rd party widgets don't work : you can set them up but if you reboot the phone, they don't update. The recent apps tab works with gestures and 3 button navigation but only with the stock launcher, which appears to be launcher 3 but is named quickstep? 3rd party launchers load, but can not access the recent apps tab. Some 3rd party apps refuse to load producing various error codes. The user interface feels like someone had an iphone and tried to model it's interface to this phone. This person did not succeed.

I have emailed the company my complaints and reasonably expect nothing to happen as I am sure the person who did this to this phone did it on purpose. May they be cursed with pubic lice and hemorrhoids.

That being said, if the phone's UI could be fixed, it would be a really nice phone and I have plans to mate those POGO pins with an Arduino or a PI because, let's face it, they aren't gonna make any accessories, are they? But I can make some really neat ones out of an Arduino and a 3d printed cover that fits over those POGO pins.

So the plan will be: 1. Root the phone - accomplished. 2. Compile TWRP against it. 3. Modify the stock rom so it it is fully functional. 4. Begin development of a customizable Android 10 rom. 5. Begin development of an Android 11 rom.

At this time, I can confirm that the bootlooder can be unlocked, you can sideload things with ADB, and a stock rom apparently exists and can be accessed through the Oukitel website. There is some kind of flashing tool too, but everything is in chinese. I downloaded the stock rom and it appears to be the same build as on the phone. I tried flashing just for giggles but kept getting signature errors. There was something in the chinese instructions about coping and renaming some files prior to flashing but I have not had time to figure it out yet as it is all in chinese.

I will be trying to extract the boot img as it appears that Magisk would work if I can patch the boot img and reflash. If/when I am successful, I will post it here. Any help is welcome.
