[Q] Awful battery life and Google Play Edition Rom questions - One (M8) Q&A, Help & Troubleshooting

Hi,
I am thinking to flash a GPE rom on my international M8, S-off with Twrp, as I can't no longer stand the very short battery life. I am already using a reputable sense custom rom here but still the M8 can barely survive a day with minimum to medium use (one to two hours browsing, 15 minutes whatsapp, one to two hours music); the battery saving mode is always on, no malware running in background, wifi scan off, account sync on, no blinkfeed homepage, NFC off etc. I used Samsung S3 with custom rom before M8 (with exact same apps on both phones) and it used no battery during sleep yet every night M8 loses 2-4% without any apps waking it up (I checked both internal battery status and GSM battery app). How odd is that?
I wonder if it is normal or there is simply hardware issue in my M8?
Is the battery life much better in GPE rom compare to Sense rom?
Does the camera in GPE rom come with HTC eye experience and any kind of camera enhancement? If not, how's the camera?

Battery issues are almost never hardware. It's your usage, setup or you have some issue.
No one can offer you anything but guesses without "useful" screen shots. And hopefully you're rooted, cause to see wakelocks requires root.
See the battery help thread in my signature. Read posts 1 to 4 carefully. You can post the recommended screen shots there if you wish. But make it clear you're on an M8. ?

[Q] H3G UK Battery Life - Custom vs Stock

Hi guys, I'm on Three in the UK and have their branded version of the One X (CID: H3G__001 if I recall correctly).
I was wondering what experience you guys have had with the battery life on custom ROMs vs the stock ROM?
I flashed a custom Sense ROM onto the device pretty much as soon as I got it and was only ever able to get about 2hrs screen on time (even with super low brightness, no syncing etc). I then moved onto AOSP when it came out and used various ROMs - CM9/CM10/SlimJB etc. On these I was struggling to even get 2 hours screen on time, even with custom kernels that managed a deep sleep of >80%.
I thought this was just the device and lived with it for a few months.
I have no idea why, but I decided to return to the Stock Three ROM using an RUU. The battery life is MUCH better than anything I have ever experienced on a custom ROM and the deep sleep percentage is even higher than Ncx/faux kernels.
Screen on: 3hrs approx (Default stock autobrightness)
Time unplugged: 17 hours approx
Deep sleep: 80-90%
What I'm wondering is if any users here have had a similar experience using the One X on Three UK?
I suspect it could be something to do with the network drivers used on custom ROMs, since Mobile Standby always seemed to use more battery than it does now. Yes, I had made sure I had the correct RIL, but I'm talking here about the baseband itself.
Cheers,
James
Hey man I have a 3 branded handset. Was running stock for all of 12 hrs tops. But I have previously ran stock with my old hox's and battery for me was shocking.
I'm now running renovate with ncx kernel -125mh which is running like a dream get 4 hrs screen time and I have had a record of 15hrs standby. I do use my phone a lot tho during the day, some helpful advice is if you use wifi switch your data off and also don't have auto brightness on.
There are some useful tips all over the hox forums for battery life but this is just my point for you

Hey man, thanks for the reply - this is why I was confused! CPU clock seems to be higher on stock and obviously one would expect the battery life to be worse. But it's definitely FAR better than anything I've managed to achieve on any custom ROM (Sense or AOSP).
I know all the tricks such as turning off syncing, checking BBS, dimming auto brightness etc. and nothing seemed to help while running a custom ROM, the standby/usage drains were just terrible.
The only thing I could think has effected it this time is that I've fully restored using an RUU, which has in turn wiped the internal storage. Perhaps there was a dodgy file that was causing poor battery life...?
Other than that, the only thing I can imagine it being is the network driver.
I don't entirely know about an sd file but it could have been and app running in the background. Tbh I never stayed on stock long enough on any of my hox's but Iust admit I do get very good life from renovate ics. As we can't boot a sense jb yet I can't comment on JB sense roms.
I must admit aswell I haven't tried aosp as I'm holding out hope on 3 with the update.
Try renovate rom out I was hesitant with it am very happy, before that I ran pkmn rom with is now discontinued but there is viper rom by the same Dev and that also gave me exerlent battery

[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.

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?

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!

Suggestions in buying this phone

Hello guys, I am really interested in buying this phone and I don't want to make a mistake, as this maybe will be my phone for the next 2-3 years, maybe more.I want to know your opinions, does this phone worth to buy? Does it have that annoying bloatware that slows the phone alot(I have a s3 now and I know what I am talking ) and in everyday usage does it work smooth, how is the multitasking and the battery in normal usage (fb, calls etc)?
Also I am between this and the LG G3, I can see a lot of negative thoughts about M8 camera quality,is this true?
Thanks in advance and hope we'll meet in this forum shortly
1) What bloatware the phone has, depends on what variant you buy. But I think the Euro version are pretty clean (at least compared to some of the bloat-ridden US versions). In any case, the phone is very smooth and fast. Some folks complain about lag on Lollipop (known issue on LP in general) but I don't see it. In any case, the phone is not plagued by OS lag like the Samsung GS5 and tablets.
2) Most folks that complain about the camera don't know anything about taking pictures, and are just looking at the MP number, not the actual image quality. M8 camera loses some detail in daylight. But probably only important if blowing up or cropping the photos. The camera excels most other smartphones (at least for its "generation") in low light. Which is particularly important if you take a lot of pics indoors.
There are some other opinion on the following thread, that includes one guy that is considering ditching the LG G3 for the M8: http://forum.xda-developers.com/htc-one-m8/help/wrong-t3069102

I get around 6-7 hours of screen on time with 4g/3g and 1 hour of gaming. I can't finish the battery in a day on normal use. I don't have the time. Refer to this post and thread for screen shots. I don't run with gps or location on when not needed or auto sync.
Most bloatware from carrier I could uninstall (I'm on vodafone, not sure about orange or telekom) and bloat from HTC (useful stuff but if don't need it is bloatware) like kid mode, dot view mode and such can't be uninstalled. Stock Sense is fast, the fastest I ever seen on android and the speakers will blow you away first time you hear them
Rooting and flashing roms is easy and you don't need S-OFF for that but make sure you do a nandroid on your stock so you can revert and take the otas when needed.

The above response from TempesZ is better than I can give on this; as I'll have to admit I'm personally not a heavy user on the phone most days (on work computer all day, than mostly use my tablet at home in the evenings). But with light usage, I can get up to 48 hours on a single charge. If my kid uses the phone to watch movies or play games for a couple hours, I can still easily make it through the day with some charge left by the time I put it on the charger before bed.

if you want a phone to put in your pocket to keep things warm in those cold winter days, then buy an M9 http://www.androidauthority.com/htc-one-m9-overheating-594799/

It looks to me like HTC tried to cheat on benchmarks (by turning off the thermal throttling) and it backfired! And most of the smartphone manufacturers do cheat on these.

How do you manage to get such good battery life? I get 5.5 hours of screen time at best. That may be due to me having horrible service in my area. Still running stock Lollipop.

Depends what you are doing with your phone. 7 hours I hit in wifi and without using chrome too much (read hours) and instead relying on things like tapatalk and apps and no games. I am using Maximus HD with stock kernel. I have good signal (always 100%) and brightness usually is low enough and at night is at 0. I can tell you brightness makes a massive difference. I don't use auto brightness but manual and never use gps and location unless I need it. For example if I browse XDA through the xda developers app I get around 11-12% per hour drain on wifi and around 15% on 4g. (check picture, 20 min screen, 4% drain)
Keeping wakelocks to a minimum helps a lot to conserve that extra juice for your screen time. I use my android tools to disable wakelocks and greenify on stuff like facebook. No auto sync either since that would be only my mail and I don't need sync for that.
If I game and have WiFi on I usually hit 6 hours with 1 hour of games or so and that's my average sot.
I don't use Google apps except Google newsstand that syncs only when I want to read it and Google play services which is mandatory. No Google+, no maps (I use waze), no gmail ( ok maybe I use inbox with no auto sync). In Google settings I disabled location history and of course I don't use Google now (another useless drain) though you might use it.
I don't use blinkfeed, I use nova launcher.
Oh and power saver kicks in at 15% and it helps for the last hour or more. It reduces your CPU from 2.3 to 1.2 ghz but I think it's worth the performance impact at that point. 5% is extreme saver time but I never let it go that low on purpose

Cell Standby/Phone Radio after Android M Upgrade

I have read numerous posts about the Android L cell standby bug on the One M8 and used that to make as many changes as possible before posting here. I haven't seen many posts where the HTC One M9 was affected by the MM update in this way.
I have had my Verizon One M9 since March 2015 (preorderd it), and it worked great on Lollipop. My cell standby was consistently under 5%. Then, I upgraded to 6.0 around March 2016 and have been noticing consistent battery drain from what I think is the Phone Radio (Gsam) or Cell Standby (stock battery app). It is >40% with the screen on and >30% with the screen off. Airplane mode appears to help with the cell standby percentage (down to 5% after 12 hours, battery down by ~15%). I am also having more issues with the phone heating up; 114 Fahrenheit was the highest I noticed before it stopped functioning from the heat.
What I've tried:
-Verizon's Repair Assistant/Software Upgrade Tool
-Factory Reset
-Wipe Cache Partition
-Clear Network Settings
-Turn off Advanced Calling (seemed to help the most)
-Switch from Global to LTE/CDMA
-Keeping WiFi off unless I'm downloading something (helps the WiFi battery drain issue)
-Location off
What I have NOT tried:
-Booting into safe mode (my apps don't seem to be misbehaving per Gsam or the stock monitor)
-Unlocking the bootloader and flashing a custom ROM. (I'm S-On with a Locked Bootloader.)
In all fairness, I get good battery life (2 days) if I don't use my phone (<1 hour SOT in a day). If I use my phone, it dies in like 6 hours. I lose over 10% per hour of active use (Chrome, texting, Gmail). I don't have Facebook, Twitter, or G+, but I use Hangouts.
Reason I'm concerned: People I live with, same contract have a 1% cell standby (Samsung Galaxy S5 on 6.0.1). Why is my phone's cell standby so high even though this issue was supposedly fixed for MM?
Thoughts?
Hi, I agree, its pretty bad. You are getting better battery life than I am...
I've been on a stock rooted/S-Off for only three weeks or so, but am considering going back to my M8 because the battery life is so poor. (and I actually would use FM radio , which I can not on the M9 Verizon)
I run no social networking apps, have uninstalled everything I don't actually use.
GSAM tells me Google Play services is a culprit, so just today I've removed my Google acct, location turned off unless I need it, and will test over the next day or so .
I'm waiting for a custom rom probably HTC 10 port to get rave reviews and will likely give that a go .

I'm not rooted yet. I noticed high Google Play Services usage (don't remember the exact percentage and didn't screenshot it) a few days of upgrading to Android M. It seemed to help to backup my data, factory reset the phone, run Verizon's Repair Assistant/Software Upgrade tool, and turn off Advanced Calling. Now Google Play Services is calculated at using 10% of my battery since last full charge (4.9% per GSam App Sucker). The cell standby issue was probably there all along, but I just didn't notice it until I tamed the Google Play Services drain. Maybe doing what I did will help you. I can't post outside links yet, but if you Google "Verizon's Repair Assistant - Software Upgrade (HTC)," it will be the first result that comes up.
Edit
I suspect my phone's issue is a reporting bug, as some other posts have suggested. I feel bad complaining since I get great battery life if I don't use my phone. Comparing phone radio usage with airplane mode on for 12 hours to not using my phone for 12 hours (airplane mode off), the only difference was in reporting. It was 5% with airplane mode on and like 35% with it off. Same amount of battery was used. Perhaps the screen is really what's draining my battery. All I know is that I used to get double the screen-on-hours while running way more apps when I had Lollipop.

I'm quite sure I have this same problem. I've only had my M9 a week, and am seeing some strange and inconsistent battery drain. The majority of time if I'm doing a simple task like texting or checking e-mail, the phone gets warm (warmer than anything I've used). Battery seems to deplete quickly too, mainly with some from of google services being the culprit. However, I've also noticed high mobile radio usage. I can see that the mobile radio is active pretty much the same amount of time phone radio is, even when on wifi....I've never experienced this before. It is as if the mobile radio is constantly locked on (which I noticed there is a check box for this in dev options). I know the Moto X 2013 had this same issue when updating to L, and was never patched. I came from a Droid Maxx, so maybe I was spoiled with battery, but I can almost sit and watch my battery drain on this M9 (and thaw my hands if necessary). I also have rooted every android I have owned, and decided I don't want to root the M9 and take a break from all that. Immediately a bit annoyed with the heat and abysmal battery life. That said, build quality is great, and the user experience is quite good and fluid (aside from ridiculously pointless pinned notifications like when boomsound is active or when you connect to wifi and it reminds you you're connected....both mind bogglingly stupid and take up way too much of the notification panel).
If I have to disable a bunch of features to get it to not heat up and/or use less mobile radio, most likely will sell it. Unless rooting and romming helps? Though initially I'm not seeing much development on this M9. I want to like this phone so badly but these problems that shouldn't be problems make it a bit hard to do so.
