Jelly Bean Draining Battery

Hey,
I recently unlocked my bootloader, rooted, and installed CM10 on my HOX. I did a full battery drain and then full recharge before using, and still noticed that my batter is still being drained at a worrying rate. (3 hours gone and just 57% battery left) The screen takes 52%, but the Android OS takes 21% and the Android System takes 5%
Is there anyway I can reduce this battery drain? I understand the ROM is still in Alpha, but I've heard people still achieving 3 hours screen time with it! Maybe something to do with getting a new efficient kernel ? (I'm still new to all this).
Many thanks in advance

Firstly, what kernel are you using?
Give it a few days to settle in first.

Stock kernel I presume :/

Try another kernel after a few days of letting things settle in.

hi there - just a thought of sharing with you since you've already rooted your phone -
- Domination ROM CM10 thanks to Owain94 check it out on the forum http://forum.xda-developers.com/showthread.php?t=1799375
- NCX 0.99bOC kernel by n3ocort3x see comparison here done by nimrodity (thank you guys) http://androidroots.com/king-of-kernels-kernel-comparison-htc-one-x/
Again it's a custom ROM expect for some bugs to come up - but you decide at the end since this version are better than alpha
Enjoying the flexibility & efficiency of the battery life on my HTC One X!

[Q] Can firmware be related to battery life?

Hi all
This may seem like a stupid question but I'm racking my brain for solutions.
Previously I've been quite impressed with the battery life on the M8, however recently updated to the most recent firmware so I can use the current version of ARHD and since then I've seen a considerable reduction in battery life. For example, today I've been off charge for just under 12 hours and have used the device very little (1 hour 26 of screen on time) and I'm down to 20%, with screen usage right at the top of the battery use chart. I've tried different ROMS, into a GPE ROM, only to see this poor life continue.
The handset was bought from Three in the UK, and on baseband 1.19.21331147A1.09G-20.57.4196.01L_F.
I'm at a bit of a loss basically, and trying to narrow down a culprit. If anyone has got any ideas I'd be very thankful.

I think so, I've been having problems with mine recently but I thought it was because I'd rooted and then unrooted back to stock this week. Now I suspect it might have something to do with the latest FW. I'm managing around 18 hours but there's something keeping the phone awake so it can't get into a full sleep and save the juice.

Hi guys. I'm on the latest FW2.22.401.4 too. On my main uni (rooted but stock) I'm not confronting such problems. But on my secondary unit with ViperOne (M8) installed I'm having such problems sometimes (not always). Think this is quite wired, as Venom works with the stock kernel ....

Absolutely. Firmware contains radio baseband, which IMO cell reception is one of the greatest contributors to battery drain (aside from the more obvious factors like screen on time, runaway wakelocks, etc.). It could be that the new radio does not happen to play well in your area. This would also explain if some folks are getting better battery life than you on the same firmware, as reception is often a local factor.

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!

Bad battery life after March OTA

Hello everyone, I was getting EXCELLENT battery life on my phone consistenly ( 7 hours of SOT over 30 hours ), until I flashed the march OTA.
Do you think factory resetting the phone may fix the problem ? or maybe something else ?
My phone is rooted with stock recovery.
Thanks

Only one way to find out my friend. Many folks have done that very thing since 9.0 hit last August to rectify poor battery life. Personally, I do that very thing every 3-4 months just to keep things cleaned out. My P2XL is 18 months old and I still average the same SOT as I did when I got it :good:

I tried a factory reset too due to low battery life. At december path I was near the 8hours.
Now it's more like 6h-6h30. It still good but far away.
Today I desactive in "options for developers" and 'tracking system" both slides. Battery life seems better. I will see later.
