[Q] Battery life poor since JB

Hi everyone,
My One X used to have brilliant battery life. I didn't turn on the screen that often throughout the day, but I was able to regularly check the news, send and receive texts, make a few calls and - crucially - keep my Wifi on for the entire day. With this setup, I was regularly getting 4 or 5 days of usage without having to charge my phone. However, as soon as JellyBean came along as an official update, I grabbed it... since then, I'm lucky if I get a day and a half out of it before I need to plug it into the wall.
I'm not running any custom ROMs: just whatever I get through official O2 OTA updates. Battery usage says that 36% of my drain is due to Android OS, with another 20% due to Maps. The rest are tiny, only 2 to 5%. Now I understand that a new version of Android might make some new demands on the hardware, but from what I heard, the update was supposed to improve battery life if anything. Even with the new Power Saver feature on, the difference is minimal, with only a few hours standby time gained overall.
Can anyone suggest anything to remedy this, or is this fairly normal? It's not world-ending and perhaps I was just really lucky to get 5 days of use in the first place, but thought I'd ask the experts before I grin and bear it. Thanks in advance for any help or advice.

19 hours and 40 minutes into this usage cycle, I've got 57% remaining. So it's shaping up to be about 40 hours of usage, down from 120 at its peak. Right now, it's also saying that Android OS has used 99% of my battery... and nothing else is on the list.
Does no-one have any idea what's going on?

Did you make an hard reset when you updated your phone?
This is why when you upgrade your phone to a newer Android version it is better if you perform a hard reset

AW: [Q] Battery life poor since JB
I suffer(ed) also under heavy drain due to maps since update to JB. But I'm convinced it's cause of Google Now. Disabled it yesterday and will check whether it gets better or not. Try disabling gnow and see if it gets better. I also had issues with gsam battery monitor in case you use this.

Would you consider rooting because custom roms like blade have great battery life

Thanks for this. Your suggestion got me checking for other people having issues with Google Now and battery life. I disabled it as you suggested and I'm definitely seeing an improvement. It's still not as good as it was, but I think I might be able to squeeze more than two days out of it now.

Do you have stock rom? Because I've just upgraded to JB yesterday and flashed a custom rom, and since then my battery is like 3 times more powerful.

You should definitely switch to a custom rom... Ever since I upgraded to JB I've seen a massive improvement in my battery life.. From barely making it through the day to almost 2days of my typical of usage.
Google Now does seem to kill battery as it polls the Google maps app a lot.. So I usually open task manager to make sure it isn't running in the morning background.

Chronic battery issues with a variety of ROM's

Hi,
I've searched through various threads here and in the development/ROM forums but need some advice and didn't find advice for my specific scenario.
From Jan - Sept this year I was rooted but running the stock 4.1 Android (Rogers), I tried CM10 and a few other custom ROM's but eventually went back to stock carrier TW, with the only root change being the 4.2 Camera (for Photosphere) being installed (via CMW). During that time my device ran pretty ok in terms of battery life.
Then in Sept I started getting serious battery drain issues. I've got a few extra batteries and an external battery charger so I ended up swaping in and out charged batteries twice or three times a day.
So I decided to re-enter the root world and have since tried a variety of ROM's to see if the battery issues might be fixed. Installed TWN recovery rather than CWM, Tried ROM's such as Task650, CM10 Stable, CM10 Daily, and I still am encountering pretty dismal battery life?
I've tried various battery apps and generally keep screen brightness to a minumum, turn off mobile data, and have wifi/gps/bluetooth/sync off for most the day
I can't imagine it's the battery themselves, 1 is the original that came with my GS3 last year, 1 is official Samsung bought a few months ago and two are Anker ones that worked fine for months.
Can anyone recommend a specific ROM that may have worked for you? I haven't really messed around with custom kernals much, only played with kernals and governors a while back when trying out SETCPU (which I havent used in ages).
Any ideas?
Thank You.

Try the app BetterBatteryStats and see what is using up the battery. After a few hours of having the phone idle, look up the process running on the phone that uses the most wake locks.

Hi,
BBS did not really reveal one glaring thing draining the battery while the screen was off.
Any other ideas?

[Q] Sense -> GPE battery life decrease?

I converted by HTC One M8 from Sense to GPe a couple of months ago. I did not receive any issues going through the process (rooting, s-off, installing new RUU). As it happens, I liked Sense and had good battery life, but the phone was crashing a lot, slowing down to a snails pace a lot, and multiple resets did not help.
On GPE, when I loaded everything up the first time, the battery life had decreased dramatically. GSAM was after a few weeks reporting ~2.20 average screen-on time. A month later, fed up, I reset the phone again, and am now getting about 4.15 average screen-on time. Better - but still not great compared to most of the posts I see on this topic.
I have Lux installed (I much prefer darker screens anyway) and there's nothing seemingly outrageous in the battery stats in BetterBatteryStats, GSAM, or Android's own. I sync photos to G+ only when plugged in, I have GPS on to Battery Saving, etc.
The one thing that feels different between Sense and GPE is that the LTE indicator seems to show generally less signal than it did before. When I switched to GPE, I did not go in and flash a new radio; when I checked, it did have the GPE radio firmware (baseband?) version installed. Recently I happened to be in the UK, where my carrier there does not use LTE, so I switched to 3G-only - and this seemingly had no effect on the battery life. Usually, I am in downtown and and northside Chicago, and T-Mobile LTE reception is generally good here.
So my questions are:
1. Is that battery life within tolerance?
2. Should I be doing something with flashing a new radio? (I think not, but wanted to check)
3. Does re-flashing the RUU seem like a good idea? (not sure exactly how, but I know its out there on other threads)
4. Could the unit be faulty? (I would have to re-set it back to Sense if so... )
Thanks in advance for any expertise you guys can offer.

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...

No, maybe like 2 - 3% at most overnight.

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!

Question Phone Overheating - Is There a Fix?

I'm on Android 13 and was hoping this would sort out the overheating problem I had with Android 12 (I read in a few places that it would), but it did not. The phone gets very warm when charging, and hot when streaming video, and just generally through simple use, nothing particularly demanding. I haven't rooted this phone because I did not see the need, but I would consider it if it was the only way to fix the problem. Is anyone experiencing the same, and does anyone have a solution?

I could be wrong but generally speaking in my experience, going from one major upgrade to another the phone works a bit harder to re-train itself to your use patterns. I just did my upgrade yesterday and experienced some slight to moderate heat as well. I also noticed that battery is draining a bit faster which I think again is part of the process. I'm going to give it a week or so and if I'm right it should improve.

I'm biased because I've had my Pixel 6 Pro rooted (and updated every month) since last November, and I also use Kirisakura custom kernel with its companion apps and currently have the one app set to the maximum battery savings.
So I can't really compare to 100% stock unrooted with the stock kernel, as I'm only briefly on the stock unrooted kernel each month after I manually flash the latest update.
Several others have commented, and I've experienced too, that with Android 13, we've no longer experienced as severe higher temperatures when charging. I don't remember if the others were rooted and using the same custom kernel, or if these were general Android 13 comments, so your mileage may vary. Sorry I can't give you any more concrete information.
Good luck!

Granted this is for my 4a5g but I wouln't be suprised if/when I get a 6 that its battery performance would be less than stellar after a good days use of phone and/or screen and radio/network. i.e. stock. Before I went to Lineage on my 4a5g I think my battery would cut a good 30-50+ percent each day. I put lineage on it and I poop you not, can go from a 75% to around 20% in about 5-6+ days. I tend to have my screen brightness around a little less than 1/4th on the slider bar.
When I had an HTC M8, after around 2 or so years (this was around 2016/7 or so. got phone oct '14) on the stock firmware the phone couln't keep it on for more than a day. Ran ViperRom for a bit then switched to cm/lineage and that stretched my usability of the phone another 5 years. It got to the point where the phone would shut off when it got to around %50 charge and go ding dong and turn off--without pluggin it in I had about 8 hours run time on it. My battery was beyond gone and no way would I have gotten that usability on the stock rom.
So, to answer your question, yes, trying different roms and kernels (rooting) could be to your advantage to prolong the life and performance of your phone.
Even if you choose to run the stock OS, with root, you could disble any bloat running in background. Kill any programs/services leeching CPU (and hence battery) cycles. You could definately make it run more efficient for YOU. Maybe not for the next guy who needs his facebook, twitter, ticktok apis and stuff loaded and at the ready. Everyone is different. But they tend to make the phones (they think) for everyone. in mind and as a result, device performance and lifespan become affected.

I definitely have heating issues and this is on a warranty exchange. The 2 previous P6Ps had all the same issues as this current device.

My phone was hot on A12 (41/45°) and since i clean flashed A13 and wiped it is cold (32/35°) for the same usage.

Greetings.
Good topic.
I have bought this phone a day before. I'm facing device heating even under simple tasks like scrolling messengers, browsing etc.
Previously I had OnePlus 7 Pro (Snapdragon 855), that one was cold all time except while charging or playing games.
However, Pixel looks warm or even hot even upon light using.
I'm a bit confused about that.
Is it a common problem of this device? Or probably exactly my device is affected?
I haven't faced overheating or alerts about that, however, it feels hot for my hands that got used to feel a cold phone while low load.
Currently, I have about 37-38 degrees while browsing on XDA and writing this post.
Just wondering that digits you have?

I did a warranty exchange on my P6P for a different issue and I'm glad I did. My replacement device has much better thermals than my original. My original one would get quite hot while charging and restoring apps and was almost uncomfortable to hold and to the touch. Could always try a warranty exchange and see if the replacement device is better for you. Also, Kiri kernel has been reported to help with the thermals. I've seen several reports of users commenting that their device runs cooler. Good luck!

I had heating issues and battery issues when I first received my P6P. Once I got it out of the box, I set it up and restored backups, rooted it, updated to android 13 without wiping, rooted again, and then flashed the Kirisakura kernel. I decided to try and flash android 13 again but keeping the -w flag to wipe userdata and didnt restore my backups and I've had amazing battery life and no overheating. If you haven't yet, try doing a factory reset. As simple as it sounds it may very well help

My fully stock P6P (on A12) gave an overheat warning yesterday while we were having a day out, it was only 22°C although we were in and out of the sun as the clouds rolled by but the phone was showing 46°C after being sat in my pocket.
I think Google have released the worlds hottest running phone, i have never owned a phone that heats up so much and so fast.

Thing is I have never experienced overheating on any phone (that i have owned) in UK before, using an Exynos as the basis of Tensor and then whacking an extra big core in it was a pretty bad idea unless you live in a fridge.
