[Q] Battery calibration anyone succeded?

Battery calibration anyone succeded?
Hi I have a battery calibration problem on my GT-N5110 Note 8.0 that I bought refurbished through amazon. I know it is the calibration since the battery usually drains pretty fast and when it gets to 1% it stays there for around half to one hour of continuous use. Also sometimes when I'm charging it, it jumps from around 60% to 100% and "charged" shows up right after that happens, when I unplug it and use it, then it goes down normally (fast) 1% at a time, even though that big jump while charging happened.
I have tried several "full cycles" without success and haven't been able to find a real way to calibrate the battery meter, neither here or on google, and since I didn't buy it in my country, local samsung support say they can not help me.
I'm on 4.2.2 leak rooted and the drain has been present since I was on 4.1.2 stock.
If someone can get a hold of how to calibrate, it would be really nice if you could share it! Thank you!

I tried the battery calibration app before, and really didn't do a thing for me...

I also suffer this weird battery behaviour with the device charging, it will take ages up to about 60%, and then instantly its at 100%
I also get this on the way down... when im using it, the battery drains fast, but when I get to 35 -40%, I then suddenly get the low battery 15% warning flash up, and then im all out of juice.
This is the same whether im on 4.1.2 or 4.2.2 custom or stock firmware
I rarely get more than an hour screen on time, and thats with fairly low brightness and power saving mode on

If someone could some how contact Samsung and ask them about the real calibration it would be very helpful for us having this issue... Since some don't live in the US and don't get the correct support :what:

I need help with this too!
Battery decreases so quickly when wifi is on! hardly get a days use out of it...:crying:

One method described in the battery performance thread which I've found effective:
"I wanna share my trial of battery calibration that really make a significant different at least till now .. I used to make calibration by discharge / charge cycles, but this time i add an official instruction of Apple:
- discharge the battery by ur normal usage till 1% then let the device play an HD movie till it shut down (that may take some time as it for me takes 4 hours!!) then turn it on to make sure the battery read 0% (my previous calibration the battery always shut down at 1% and I never see that 0% as I was discharging it vigorously) after making sure it is 0% it will turn off by itself anyway.
- now leave ur device turned off for extended time (about 5 hours or more is better according to apple "u could let it while u r sleeping"
- after that turn the device on and plug it in as it is on
- left it charges as it likes (for my trial it takes 7 hours and didn't say charged!! but I had to unplug it as I had to leave the work!)
till now my battery is really significantly improved, hoping to continue like that and I will keep u updated
Hope that helps :good:"
Discharging it completely, leaving it dead overnight then giving it a full charge by plugging in as a soon as it powers on has yielded good results for me. However I've also discovered a severe battery drain bug in stock Kitkat which has nothing to do with battery calibration; using wifi on certain routers causes Android OS wakelock which persists in deep sleep. I use my old Galaxy W as a hotspot for my Note 8 and consistently my battery drains overnight in deep sleep with wifi on. At my workplace we have a Linksys E2500 router, I leave the tablet on wifi throughout the day and don't notice the Android OS wakelock. So if you're having inexplicable battery drain test your Note 8 on different routers.

Calibration is a myth... google stated calibration tools do not help with how Android functions with battery management.
I posted my thread about battery and charging cables, and replied an a few topics like this one, yet nobody will search on Samsung DVFS disable or take note of it as being the cause.
Root with saferoot if you have not rooted, install xposed framework if not done so, and Wanam Xposed or Wanam DVFS disable. Since over 10 months now, my battery stats and performance are trouble free.

I was having severe battery drain for a while until I tried something I read about. What you do is carefully open the note up and disconnect the battery for about 15 minutes (they recommend a longer time but I don't see the need). Connect it back up and put the note back together.
It worked for me.
Google it, there's even a video on how to do it.

I was down to 3 hours or so of battery time but bought a replacement battery from a company called New Power 99. Cost $65-ish US and now I can go all day and still have at least 25% when I hit the sack at night. Huge improvement for me! I"m not a heavy user but I take notes at work, do some surfing, then read and surf alot at home at night. So far it's been great! Might think of a replacement battery. Probably cheaper one's out there but I wanted to get what I paid for so shelled out the extra.

Hi! Thanks for the info! That's great to hear, one question, did you change the battery yourself? If so, could you provide a hint on which guide you used, that would be verry helpful:good:

The battery came with a DVD that explained it (with really bad music) but the bottom line is you pry the back off, take the 8 screws off, unplug the old - plug in the new and replace everything. Not really hard but, as I said, nerve-wracking! I was afraid I'd screw it up but it was pretty straight forward.

That's awesome I would like to buy the same one in case something goes weird and need instructions to follow. Do you remember anything about the seller/model/site you got?

Yeah, just go to Amazon and search for "new power 99 battery replacement kit". Then pick Note 8 from the list. eBay has them too.

Will do! Thank you very much! [emoji4] [emoji106]

Any time. Hope this works for you. It did for me.

I. Had the same issues, I just took off the back cover and disconnected the cable that connected the battery. I did not need a new battery. The toughest part for me was disconnecting the battery cable... I actually had to take out the 8 screws that held the battery in place, so I could get some leverage. I only had my battery disconnected for only 5 minutes and it solved the problem for me..... Good luck!

Battery Sudden Drops

Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?

Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.

So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...

How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.

I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.

Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.

Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.

I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag

I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!

Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.

Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.

I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten

Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.

Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.

[Q] Dead end with Samsung can I have your feedback please

TLR Anyone willing to see if their tab pro drains battery when fully powered off. Like overnight when you're sleeping or at work. Thanks
Hi,
I got a 10.1 tabpro back at the end of Jan. I thought it would be a massive step up from my Nook HD+ (rooted) but it's not. Not only is it slower than expected the battery life is atrocious. Samsung advertises over 2500 standby hours for their 10.1 tablet, I get 200. Also I get about 6 hour video, mp4 files, not 10 and I don't like a bright screen, I know companies exaggerate but this is daft. But it's the standby that's a problem, having to charge it every few days in case I want to use it is a big step down from my Nook.
It's been into Samsung repair 4 times now and I'm currently at a dead end.
Problem
It loses 0.5% an hour on standby even with wifi, gps, updates off etc
It loses 0.5% an hour fully powered off. Fully powered down. OFF, not on standby. Just to be clear
Compare this to my nook with a smaller battery capacity which loses less than 1% a day. I've tried turning off other android devices (mobiles & tablets) and none lose battery over 12 or 24 hours when powered off.
Current situation
It's been in 4 times, it has been returned with a squeaky corner which they've failed to repair and the retail box is torn and tatty like they played football with it.
I've now been told
I have spoken to our product specialist regarding this and the decline in battery life over the 24 hour period is not considered to be unusual. In the 12 hour period where the tablet was powered on, even though the screen is off and apps closed down the tablet will still be transmitting, searching for system updates or connecting to networks or wireless. The 12% decline in battery is considered normal for this kind of activity.
Click to expand...
Click to collapse
This doesn't address that wifi, gps, updates etc is turned off and drain whilst it's powered off. I responded 2 weeks ago but there has been no reply.
Feedback please
1. I've been all over the internet. I've tried greenify, I've tried battery calibration, there's a ridiculous amount of bloatware that I can't delete but I've reduced apps running as much as I can. Does anyone have any other ideas?
2. What's your tablet like, does it lose battery life when powered off? I've seen people posting on here about their 8.4 inch tabpro and they've put screen shots showing better standby battery life than my 10.1 with a much better battery capacity.
I've attached some screen shots, less than 3 days and it lost 33% doing nothing on standby.
I would really appreciate if anyone could feedback on battery life when switched off, is someone able to test theirs for me?
Many thanks,
Anna

Is someone willing to see if their tab pro loses battery even when powered off?
Thanks

Uh-oh. I hope this is unusual and anomalous. I'm actively seeking a replacement for my HD+. I want to love it. I *SO* want to love it but it infuriates me that the browser crashes so often. Yours? Which ROM?

Nook is fine, It's the Samsung that's utter pants. Nook battery loses less than 1% a day on standby and screen is good. Surprisingly I thought the octo core samsung wouldn't be laggy but it is, it's not that much better than the Nook.
I have cyanogenmod 11 I think. Yes the browser crashes but that's partly because many sites are badly designed and web 2.0 is badly implemented and I use Dolphin because I like the format however it's a terrible browser for crashing. The new Guardian site I struggle with on tablets and mobiles no matter what browser for example.
Anyone willing to test their tabpro for me????

I'm actually on my 3rd day with my 8.4 it's 10:35 pm and I still have 35% left

I don't understand. 3rd day of what, off, on standby, has it been used?
Mine loses battery at 0..5% an hour on standby and fully powered off. I'm trying to establish if other tab pro's have the same level of drain on standby and powered off. Can you give me more info please? Thanks

Take the rear cover off, disconnect the battery from its connector. Bring it to a repair shop where they can do a solder work. Ask them to re solder the battery connector, this rework only takes under 5 minutes. It will fix the problem of battery quick discharge. If the problem is still the same, you only need to replace the battery, cost only around $30 for new battery.

Thanks but it was only a few months old so well within warranty.
They replaced it with an tab s 10.5 (no more tabpro's available). Tab s gives me the battery life I expect and speed. Big difference between the two is the tabpro used up a lot of battery with 'tablet idle', well over 50% whereas on the tab s it's a few %. I think the tabpro didn't quite deliver, it was discounted quickly, the software wasn't right plus squeaky case, but so far imo they seem to have got it right with the tab s. Despite the lower capacity battery and bigger screen it lasted me over 5 days and that included setting up and installing apps. The tabpro by that point would have been long dead.

I'm glad you get a new replacement but this's a common problem of Samsung tablets . Be aware of this problem is the future of battery quick discharge. Most users just simply think this is a problem of battery.

Phone shutting off at 35% battery level

Ever since I upgraded to Marshmallow, the phone is shutting off at 35%.
If I plug it into a fast charger it'll start back up. Non fast charger forget it. Battery shows 35% when I plug it in to charge.
Took it to Best Buy after speaking to an AT&T tech. The Samsung rep at BB, said he ran some recovery software to check for missing or corrupted files associated with the upgrade. It appeared that they just reinstalled the 6.01 update.
Anyways it did nothing and the Samsung tech said I could try doing a factory reset or maybe try a new battery. He then said that if the problem started after the the MM update, then that's the issue. He mumbled something about the phone just wasn't able to handle MM blah blah blah.
ATT offered to ship me a new phone with a working upgrade.
Before I go that route or try a factory reset, I thought I'd check here for other ideas.
Not happy with the phone since the MM upgrade. Along with the phone shutting off issue, it's shutting off while charging on my wireless charger, phone screen is screwed up in landscape mode and doesn't show any of the buttons that show in portrait mode.
Is there a battery calibration app that will run on this without root?

I'm a computer tech, with a VZW N4. I popped over here to see if I could help a friend with the ATT N4. Looks like he's stuck without root, but saw your post and decided to reply.
I always recommend installing 'Battery Left Widget' from the Play Store and use it on the main screen. If you want to test the battery... do the following. But I'd recommend getting a new battery. It's most likely the cause of your problem.
Go to the settings and change the 'Discharging Widget Man Text' to "Estimated Battery %". The other settings can be as you wish, but I prefer the 2nd to be time remaining and 3rd to be time dead. Do the same for the charging options.
Let it calibrate for a few days. If you see a big discrepancy between the system battery (in the top right) and the widget, you've got a dying battery. Buy a new one. My Verizon version of the Note 4 started dying at 22% and rebooting. Dying battery was the cause. I knew this because it would read 72% in the top, but 42% in Battery Left Widget. And when it would get to 5% in the widget, it would start rebooting. The other battery at the top was reading much higher. A new battery fixed my woes. However the OTA upgrade to MM did a job on the battery too.
One word of advice ... turn off Fast Charging. It probably killed your battery in the first place. The original Samsung chargers will still charge it to full in a couple hours, but Fast Charging does something bad to the batteries, and they don't last as long. I know, I've had a Note 4 since day one, and I'm on my 4th battery.
A note about MM upgrade. I have to say, I wasn't a fan either. My battery didn't last as long on MM as it did on LP. The tricks about doing a full wipe didn't help. The only fix was to get my VZW model rooted and I regained control. Now I have a MM rom that actually works well and gives me 15 hours a day of usage, 3+ hours of on screen time.

What rom you are using anyway. I have changed my battery and switched to miui 8. But problem remains same with an extended battery life... But mine won't charge more than 67% and shut down @ 12% with a SOT of 3 hours and above.

I would try your battery in another device, just as a test.
Well ... mine is a VZW Note 4, not AT&T. I've used multiple roms over the past few months. I don't know what type of extended battery you are using, but if it's the ZeroLemon, it may need a better kernel to work with it. The phone doesn't know about extended batteries without additional instructions, so charging and time to empty can vary.
I just know I will NEVER buy another Samsung battery from anywhere. I think 99% of them are fake. I went with an Anker brand and it's been perfect.
Currently, I'm running MODest v5 ROM. I just installed Nseven on a 2nd device as a test. As for the MODest ROM, after only a couple of days of testing, it looks like I'll get even better battery life than I did with PaulPizz v2 (over 16 hours of heavy use compared to the 13 with PaulPizz)

Thanks for your quick reply... Im using samsung original Stock battery and there is sticker of smart care and it is from a samsung showroom
So no idea its original or not.. Should have been original... My note 4 SM 910S SK tel korian version so the rom options are very limited. Do not have any warranty period left so im confused whether i should go for a hardware checkup... Anyway im pissed of since the marshmallow arrives....the problem started right after that update.. Since then i have changed rom changed battery.. So now i guess i have to change the phone finally... Anyway thanks for your reply..

I have the same problem with charging to only 67%
If you take out the battery it will continue charging to 100%.
All this cr*p started when updated to MM
Going back to stock 5.0.1 and doing the #*0228# reset should help.
And samsung batteries are a disaster, even the genuines ones.

Question Horrible battery and slow charging on Pixel 6 Pro

I've had the phone for about 2 weeks. The battery life is horrible. I leave the phone charging over night and sometimes it stops charging all together. Last night I went to bed with 100% charge. Left phone laying on night stand. Woke up to 70% battery after 8 hours of doing nothing. Mobile network standby used 42% of my battery drain. What is going on with this phone? Should I get a warranty claim replacement?
edit: 11/30 Turning off Adaptive battery and Adaptive charging helped. However, still getting a replacement phone. I get no signal pretty much any where. Thought maybe it was because Tmobile network. After a few days of troubleshooting the phone and getting new sim card and esim, I literally get 1mbps downloads if any connection at all. On Pixel Reddit many others are saying their P6P is getting no data, seems to be a modem issue?

Check in the settings if "adaptive charging" is enabled. I believe it is by default.
This feature attempts to sync up your overnight charge with the time you wake up.
If it's miscalculating when you wake up, it might not be charging enough. It should eventually learn when you do wake, assuming it's the same time, etc.
But you can just switch it off completely and allow the phone to charge as it normally would.
As far as mobile network standby goes, I'm not sure. I've noticed in the past this is usually because little to no cell service, so the phone is trying very hard to find a signal (boosting more power to that internal module) and thus draining battery more. Do you have poor service where you sleep?

Factory reset and when ask to transfer data from another phone. Don't. You may have a rogue app.
I also have a high usage on "Mobile Network Service" but doesn't seem to affect my battery much. My overnights drain on my P6P are 5% max.

Battery charging is slow but my P6P has phenomenal battery. Set it up from scratch like I always do with a new phone.

Battery charging is definitely slower than my Galaxy Note20 Ultra, but I like the adaptive charging at night. If you set an alarm, it will trickle charge and reach 100% just before. This will prolong battery life but I think the standard charge could be a bit faster. 65W like OnePlus probably does more harm than good in the long run but a true 30W shouldn't be an issue.

the latest update doesnt fix battery drain... update ending 037... although the fingerprint sensor is better

Not another nitpick on the Pixel thread. My battery life is good, nothing lasts forever.

I've had the phone for about 2 weeks. The battery life is horrible. I leave the phone charging over night and sometimes it stops charging all together. Last night I went to bed with 100% charge. Left phone laying on night stand. Woke up to 70% battery after 8 hours of doing nothing. Mobile network standby used 42% of my battery drain. What is going on with this phone? Should I get a warranty claim replacement?

Did you check whether you use adaptive charging?
It's designed to let the phone fully charge ONLY shortly before you wake up (set wakeup timer).
I mean, it never properly worked for me, but maybe it does for you. Lol.

My Battery life is fantastic! I have adaptive battery on. When it's at it takes about 20 min of hard use to even move from 100 to 99. I have no idea why yours does that but I'm beginning to think these are trolls because so far my p6 pro is a powerhouse. Works amazing. I love this phone. Every other dam post is complaint after complaint. Even crappy phones on other forums don't get this kind of grief. Google probably over hyped the phone and people are annoyed that they had to wait to get one or it's a massive drive by Samsung to tone down the sales of Google.......Too bad Samsung won't just allow bootloader unlock to be easy and painless. Otherwise I wouldn't BE Loving my p6 pro.....

As others have pointed out, adaptive charging is supposed to slow the charging down so it hits 100% within the hour of your alarm to wake up. You can actually see it say adaptive charging on the always on display at the bottom of it's engaged. But not hitting 100% isn't what it's supposed to do. What charger are you using with it?

That's not actually a good thing unless each point takes the same amount of usage. This actually suggests that the battery level is poorly calibrated.

You got me. Been a member of XDA since 2013 and I decided to pick 2021 to start trolling.

People here asked you many questions to find out of it's a user mistake/problem, or if the phone is the rootcause of the issue.
You answered not one single question (as of now).
So it's fair to assume that you are a troll.

I'll try turning off adaptive battery and charging. I read some saying the adaptive battery isn't working right even after days of "calibrating." And the adaptive charging is new to me, turning that off also to test for a couple days.
I have tmobile and the entire area from my home to work is covered in 5G. Was working great on my S20+ for a couple days until I got the Pixel 6 Pro. I went to tmobile store yesterday. They gave me a new SIM and checked their system. I'm literally about 1000 feet from a 5G tower. They showed me a calendar supposedly they've been working in the area and having intermittent service issues, doesn't explain why I get no signal all day.
I've factory reset the phone and didn't copy over anything from my old phone, seeing if that will help.

I'm currently trying out Adaptive Battery off for the next week just to see if there's a noticeable difference. I'll be tracking it with AccuBattery Pro and took a screenshot of my a averages before turning it off.

I remember talks back in the days when it was introduced (Android Pie, Pixel 3 I think) and already then people claimed to improve their battery life by "turning that **** off" - it would be a bit devastating to know that Google still hasn't fixed that.

Wow it has been that long since it was first introduced. Time flies. Just on day one right now and I'm already seeing more screen off drain. Will see how every turns out next week.

Return it.
May be a battery failure in progress.
While many Androids can be battery hogs until they sorted out, all should charge normally with a known good brick and cable.

Hi. I'm typing this answer form my new P6P as Google decided to replace my old device. I set up my phone from scratch without transfering anything from old device AND THE ISSUE IS STILL THERE. Insanely high network standby battery drain +25% of the whole capacity. This is nuts. The employee told me specifically that I won't have this problem with my new device. I don't know what to do. I think I'll just return it and to for a different phone. Btw my partner has a non-pro P6 and he has exactly the same issue. Our sim cards are vodafone.de. Lost count how many hours I was trying to fix this problem. What a time waster.

Good luck, hopefully the factor reset fixes whatever was going haywire. Usually that does help people as a last resort effort
