Battery with 4.4.3 worse than 4.4.2

What really upset me is that my phone was fine I was using 4.4.2 stock and had good battery life even without battery saver being on... Then I went against my ownif it ain't broke don't try to fix it principles and downloaded 4.4.3 Since then I've noticed my phone wasn't as fantastic battery wise as it used to be.. I started becoming conscious of the need to switch on power saver more often as my phone was draining much quicker than 4.4.2. For this reason I can't wait to switch over to lollipop hopefully issues will have been ironed out...without a show of a doubt 4.4.3 is not as battery efficient as 4.4.2, for my phone anyway... It's a sin that android users don't have the flexibility to roll back to previous versions as they see fit really annoying that I have to wait to the next version....I'm not a hardcore tech user so i dont have the confidence to root and all that...if I send my phone back to my phone company will they roll back to 4.4.2 for me?

Is it a carrier branded version? There are apps you can use to see what is draining your battery. Its possible if you have a carrier branded phone, that there is carrier bloatware that is causing battery drain. Try to disable sync or any apps you don't use (particularly the bloat) and see if that helps.

Have a peek at the first 4 posts in the battery help thread in my signature. If you would like help, post the recommended screen shots there. And specify you are on an M8 to avoid confusion.
There's likely an issue.... Battery life can be great on any version, depending on your usage type and setup. ?

battery on 4.on 4.4 sense is 10 times better for me than on 4.4.3 ...i just go back (because i wanted s2w...hope the new kernel source will come in next days) and again further to 4.4.4 because 4.4.3 battery is just to bad...also on original unrooted

Ok just visited the battery help thread and tried some of the suggestions...before without power saving I would get 1 percent drainage every 2-3 minutes with max brightness...now reduced brightness to auto and slider to lowest level and averaging ten minutes per 1 percent....also removed Google now....this is an improvement but didn't have to do this with 4.4.3...I think some apps are not playing nicely with 4.4.3. I hear Google is making a big effort with battery management for lollipop release...

Use an app to see what is draining the battery. Otherwise you are just guessing.
You also never answered my question whether it was carrier branded, as some carrier bloatware has been known to access the data connection frequently and kil the battery.
Hard to help, if you don't respond to suggestions and questions.

Thanks redpoint, I am on Rogers Canada, actually I was just reading that some nexus users also had battery drain issues with 4.4.3 update. One suggestion there was to disable 4g as maybe the updated modem drivers weren't as efficient as the 4.4.2 ones...going to see if I can select 3g on my HTC one m8 and see if that makes a difference...I wonder if HTC have also modified the modem drivers for their 4.4.3 update too?

Still all guessing without the screen shots.
Gotta help us help you. I dislike guessing. ??

Update: well I just changed my device from 4g to 3g and the signal bar has instantly shot up from two bars to maximum five bars, wondering if this will make a difference to battery life? If so I can live with 3g

Don't like answering questions meant to help you? Weird.

Yeah? Its even worse on 4.4.4. Using the same settings, same apps, same usage patterns, my battery lasts only 10 hours. I used to get 18 hours with %25-%35 left at bedtime. Google sucks - coz, at the end of the day, the combined battery usage of Android System + Android OS + Google Play Services is more than %60!

Horrible Battery Life on Nougat

So Just to announce where I am coming from, I am a Sony fan for the past 4 years, Had the Z2 and was totally blown away by the battery life it offered. Then I got the Z5P and even though the battery performance was nowhere near the Z2 I still got through an entire day with it without issues so I was happy.
Then came the Nougat update and all hell broke loose. I am literally getting just 6 hrs of battery life since the update. And even when it is idle it still drains battery like atleast 2 percent every hour.
Also the charging is very slow. I have a quick charger that used to take the battery life from 0 to 20 in atleast 10 - 15 mins. But now it actually drains the battery if I am using the phone while charging. And yes I have switched off the battery optimization option.
Any help will be appreciated even if it is just a confirmation that I am not the only one having this issue, which will at least let me know that it is not just my phone.

There must be some process with corrupted data after de update which is constantly executing something. I recommend you to do a full wipe, factory reset

Oh did not know this could happen. Will definitely try doing a full wipe and see how things go! Thanks a lot!

I never fully trust OTA updates, because it keeps all the applications data and some special case of your current configuration maybe is not "converted" to the new version and causes the programs to behave weird. Have you looked at the battery usage? Maybe you find the process which a huge % of battery eaten, and just wiping that app data is enough

Thanks for the reply! Yeah I looked at the battery usage stats and no specific app is draining more than 2 percent of the battery over a charge. The only things that have taken most out of the battery are 1. The Screen On Time which is to expected and 2. The Idle Phone which takes around 15% consistently in every charge.

after updating to .372 , i learned from internet that this build has battery draining issues. ( i never faced any )
after updating to .376. , the phone is as steady stable as my other xperias (btw z5p is my 6th xperia )
now there is however a catch.
1. if you updated on OTA , this means the update of 1.2gb via ota only replaced certain files from .305 to make it .372 build (android 6 to 7) --- such OTA updates USUALLY ends up having problems (in general) with battery draining issues. Such problems i personally faced during updating from honeycomb to ics. - in short whenever update is available; always install FRESH
2. if your bootloader is locked then use xperia companion to install fresh after wiping all data. (makebackups)
3. if your phone is not rooted then try disabling all un necessary apps under Apps section.
----
Trivia
You cannot compare Z5p with predecessors like Z3/Z2/Z1 and Z since
1. they were always smaller in screen size / resolution and were not 4k
2. They stops at Android 5 / 6 as their last builds and battery life was awesome w.r.t consumption

however some of friends on XDA agrees that .305 (android 6.0.1) (came out dec2016) is the BEST build ever for z5p. addressed all battery issues and it was the final build for z5p on android 6.0.1
even i am thinking to degrade my phone due to ram consumption of N is very high!
this is why xzp has 4gb ram!

I need to know. If I updated my phone to .376 and it's having this lack of battery life, DO I HAVE TO SELL IT OR DISPOSE OF IT BECAUSE IT'S LITERALLY A LOST CAUSE NOW? (P.S. I immediately did a factory reset after the Nougat install completed.)
Because apparently if you updated to this build, then returned to the last Marshmallow build, THE PROBLEM IS NOT FIXED, and reloading nougat will only make things worse. And if you updated to .378, it not only does this not get fixed, it breaks your headphone jack to boot.
Please help. I am freaking out about this battery life. I lost 60 PERCENT IN 6 HOURS OF BASICALLY PODCASTS. ?

Well, after all my trials I flashed MM back and everything is back to normal. The issue is with 7 so not sure what happened to your handset
EDIT: Re-upgraded once again= battery 8 hour life. Go into About Phone, Status and disable battery optimization. The handset reboots and incredibly this morning it was like the old days .

Maybe I'll try that. The best I was able to do was 21 hours with one bar LTE, 6 hour's sleep, and 3h40m screen on time with several hour's worth of Pocket Casts.

i confirm that on build .33 i lost my battery even on stamina mode one percent every 10 minuets over using wifi , it just keeps the battery when device is screen off -_- its horrible i didnt have this kind of problem with .253 and im wondering revert back to MM

Going from Oreo to Marshmallow & Battery??????

hello there, been following this forum for ages, and a owner of a htc 10 for two weeks....
But I have a big problem....... the battery.....It really is abysmal......
I am currently on LeeDroid oreo, but have tried other roms, and come to the conclusion, the battery sucks!
I know there are kernal tweaks, but with this phone, i just like running the basic custom rom, no bells and whistles......
i am s-off and know how to downgrade/sort signal out/CID/ADB and everything, but I am reluctant to go too far back (Although I do like marshmallow)
I know on other phones, that going back to a previous firmware...sometimes improves the battery
but will it improve my battery????????

I went from Oreo to Nougat. Battery much improved. I was running pure stock rooted. No other mods on Nougat. Took a day to settle, but I could finally leave the house not worrying if I needed to carry a USB cable with me for a charge.

And overnight, do you notice any abnormal discharge? As much as 25/30%? or less?
I have this much of a discharge on nougat and on oreo... Did not noticed much of a difference on both FW tbh... As i bought this phone 2nd hand about a month ago, it was already on N and never tested it on MM to tell if there is any difference.
Our luck is the fast charge capability this phone has...

I would say so, yes I had problems. I bought this phone 2nd hand as well. A mint Red one. Pristine condition - at least in appearance. I also have/coming from a daily driver LG V20. Which also uses same 820 chipset. So I had some kind of expectation as to what battery life around. I was kind of shocked how bad the battery was on the 10. Phone was dropping like maybe 20% overnight. In the daytime on stock before I rooted I was getting maybe 1.5 - 2 SOT hours depending on use(i'm not a heavy gamer). I had never experienced such bad battery life before on an HTC phone. I unlocked it/rooted it and started playing with mods. The most success I had was with the Helix engine. I also had some Magisk modules installed to help deep sleep. Probably improved to getting 3 - 3.5 hours SOT. There is a thread dedicated to getting better battery life on Oreo in the guides section and I'd follow that thread and try various things. Also I had done the HTC calibration a few times, and the HTC battery test just to get a sense of the battery's health. In their test, I scored an 85, so I'd say the battery was OK. Not in the area of being a replacement.
But in the end, I was curious to go back to Nougat and then maybe on to Marshmallow to see how battery life would be. Simply going down to Nougat, I was satisfied. Not quite as good as my LG V20, but close enough. Don't feel the need to go down to marshmallow for it.
Maybe in the future I'll go back to Oreo on the 10, but for the most part, Nougat is fine.
From what I've read as well, HTC sort of 'unleashed' the power of the 820 chipset in Nougat, therefore when people went from Marshmallow to Nougat they reported worst battery life but improved performance especially in gaming.

Im aware on the unleashed power htc did on N, but it just don't justify the amount of energy drained. It does not make sense to remove social or other apps from background just because you need to retain battery. Still have a one M7 and the battery still is way better than this htc, with all the apps and settings i need on both, almost a clone of my m7. Im no gamer at all, and don't use whatsup, viber, FB, g+ etc.
You are saying that just by returning from Oero to Nougat, your htc 10 battery got less discharge, like it got fixed? without any mod's?
Thanks for your time to answer me!

Yeah, for me moving back to Nougat fixed my drain problems. Keep in mind, I didn't own the phone before Oreo, so I can't say what it was like pre oreo. But I finally felt comfortable with the performance/battery life I was getting on Nougat. I can't say this will work for you, but others have reported the same. Moving back to Nougat improved battery life.
Before you do it, I'd advise to rule out a hardware problem though to save the aggrivation of downgrading. Do the HTC battery test. If you fall below 70% in the test after an hour, I'd say it might be more hardware related than software.

Good morning.
Wile i was chating with you (yesterday), finally used the htc battery test and to my surprise it went from 99% to 88% in that hour test (99 because it was off and spent that ~1% booting). So, hopefully, will experience the same as the most of you who made the downgrade.
Perhaps its some part on the process of downgrading that fixes something, maybe the format of the [persist] partition one have to wipe to recover access to the baseband (thus the imei) repairs something, a kind of file system error that makes the android system use a lot of power(?).
As i told before, if do mobile repair and to this day, after several hundred of phone fix (hard and software, various brands as lg, samsung, htc,, iDeveices and china phones, never seen this type of problem unless it was hardware problems like pmic (power management IC) due to use of bad chargers / bad cables, water damage, drop damage, etc. Got this 10 and as soon i got here (xda) immediately noticed the amount of people that had the very same problem. And we are (here on xda) just a few to the many thousands of 10 owners around the globe that don't use xda or any other forums to talk about this problem.
Going to do this downgrade today. Im eager to see the result and use my 10 finally (another agnostic hope :angel!!
Thanks!

Poor battery life

Hello, i have a problem with my A2 lite. Battery life is just 2days and 4h SOT. Suspect is system consumption 44%. Have you experienced that someone? I have to try factory reset, or what? Thanks for help.

You should definitely factory reset the phone, you should not be below 6h SoT with this battery... Im regularly getting around 8 hours of SoT depending on what u use...

Same here. 1 day after the november security update and I have almost the same numbers as the OP. Coincidentally, 2 days ago my ticwatch e started draining battery dropping to almost half of what i was used to. I suspect the update messed up something.

No strange battery drain since November update on my side. Maybe an app you use was updated at the same day which is causing the drain.

Facing the same issue after november update. Same usage, same apps. Might have to factory reset
Edit: careless of me lol

So I did factory reset. Issue with battery continues. Android system and google play services using most battery, altogether about 30%. SOT is basically half of what it used to be. Google play services are on the latest Nov12 version.
Edit: Whatever is broken, it also affects the battery life of my wear os device (ticwatch e). After connecting the watch to old cell phone (ascend p7) battery drain of the device stopped

It was the fault of the november security update and now there's another security update which is going to fix the battery draining issue!

Let's wait few days to see. Installed yesterday and the phone battery looked promising... Until paired with my wear os device (Ticwatch e). Then the battery drained started again, on both devices. Google Play Services still have top usage. (I tested the watch with my old phone running on lolipop, all ok there, so it's got definitely something to do with the latest updates)

Had same issue with 1st november patch, now the 2nd seems to have fixed: again slow draining...fine!

I've also experienced bad battery consumption since my 2x November updates, from 9+ hours SOT to 5 hours (approx 2 days to 1 day)

have the same problem, bought the phone, it was offering me upgrade to android 9, i did it, and the battery cannot hold for more than some 29 hours.... i cannot see whats draining it unless i root it, because Gsam cannot see which apps specifically. anyone still have the issue on android 9?

Yes, I have the same issue, on Android 9 I can't get more than 6h ScreenOnTime. That's the reason why I prefer Oreo

GSam Battery Monitor can be granted some rights by adb (no root needed), so it can show consumption per app.
Have a look at
GSam Battery Monitor -> Menu -> More -> Enable More Stats
I ususally have less than 2 days with 6-7 SOT. If it's less, GSam shows me, which app consumed more than it should.

mine says i have to root it in order to enable it. in the same menu.
been browsing the MIUI forum, some people having the same issue, the guys who dont have that issue, are claiming its adaptive batterys fault and that it will normalise in a week or so, when adaptive battery does its thing.
sound odd, but ok.
also, it says that rollback to oreo is not recommendable because some functions could get buggy.

I had a problem after upgrading, downgrading and upgrading again. Was apparently caused by a modem firmware issue. Reflashing the modem from 10.0.3.0 fastboot image fixed it for me.
Showed up as "system" but nothing that could be pinpointed with GSam (root) other than high load in the kernel.

not true. i have done the downgrade without issues. Oreo, in my opinion, is very optimized for our mi a2 lite....im waiting a better Pie version. if you want to read how to do the downgrade here the link https://forum.xda-developers.com/mi-a2-lite/help/sim-card-issue-downgrading-pie-9-0-t3874350/page6

okay so what should i do now? after downgrading from 10.0.4.0 pie to 9.6.11.0 oreo and rooting and it got even worse than ever. Please advice me fast!

I don't know how you downgraded your phone but I've downgraded mine from 10.0.4.0 to 9.6.11.0, battery life is better than February update. Phone is snappy and had no issues at all (except for SIM2 which I don't use). I've also rooted it with Magisk.

Too fast draining

hi
i have a MI5s For almost 2 years?? and since some weeks ago my phone start to drain really fast like in 5 minutes 10% or more already drained. i was on lineage 15.1. and go back for the global version and the problem persists.
then i ordered a new battery but infortunately it has the same problem. i even installed the new developer version 8.11.15 and install again the newest version of lineage. i notice the aproximation sensor was not working and i removed it. and the fingerprint not working too. using keys on screen.
any solution for this?
best regards

Try flash to latest miui 10 global beta. Im on beta 10 8.10.25 and the battery life is really impressive compared to previous stock rom.

Go back to 7.0 firmware, reboot to system then flash oreo firmware again.

This above, or you might actually have an App installed which is causing this problem. Check in the settings -> battery -> power usage if there is some app sucking up all the power.

the problem was 2 things:
- the battery. when they replace the screen they damage the battery. the battery had a small cut that was coming out some smelly gas.
- the aproximation sensor was dead. maybe caught sweat from running.
replace the battery and remove the sensor appear to fix the drain. now my phone after charge at night, at the end of next day it still at 40%. if i am going to see a episode online with phone data and not wifi it consume 20% for 40min episode.

Ok yeah, if the battery is damaged , then it's clear
