[4.2.2] Shpongle feedback/report - HTC One V

Hey 1ce, I'm posting here because I can't post in the Shpongle thread.
First of all, the ROM is awesome, and it makes me love using my One V because of how smooth and fast it is. However, I wanted to report few things:
1. In the ROM thread in page 128, bandit97 wrote:
So is it just me that has these battery problems?
No matter what my phone is doing. Sleep, Lock, Something, Nothing. The battery continuously drains to zero. After 5 hrs of a full charge just sitting there its dead. Never mind if I do anything. On sense roms and PA 2.99 I get pretty decent battery performance. Is there some tweaks/settings/apps I'm missing out on? I love this rom and its all around performance. But I travel a lot and I just cant afford very short battery life. Its really the only thing holding me back from using this as a daily.
Are any battery tweaks being worked on or available?
Tried
Stock Clocks/1400//BFQ/cfq/Smartmax/Smartassv2/
All the same
Any advice?

I wanted to say I'm having the exact same problem...my battery life has been reduced to about 60% of what it was. It keeps draining even when my phone is on sleep. I checked my battery usage stats (the built-in feature) and it says 50% is screen display (although I have set the brightness to the lowest possible and disabled auto-brightness).
2. I noticed when listening to music, that the media volume levels have a bigger difference than I remember having in Sense. What I mean is, that I often listen to music and the current volume level is too low, but the next higher one is too loud. Is it possible to make the difference more subtle (making more volume levels basically)?
Thank you.

I managed to get better battery performance buy using V6 Supercharge zipalign and turboboost mentioned in response to what you quoted. I also ran my battery right out and fully charged it without turning it on. Then calibrated it. I still don't even get even close to stock/sense, but marginally better. It drops 5-8% overnight now.
What clocks and IO/Governor are you running? Using auto sync or weather? Do you use greenify? Could be a lot of things.

[Q] optimize HTC Desire HD

Hi new to the forums. Recently got desire hd. Have to say its a pretty nice piece of kit. Just wondering if anyone knows any tricks and tips to make it run at full speed as sometimes it lags (with usb debugging on) and sometimes it says the sim card has been removed when it hasnt. These are just minor errors. Also and tips and tricks on how to improve battery life. Its decent for a smartphone but anyway to make battery last longer.
Also what is rooting and why should i do it. What advantages and disadvanges are there to using a custom ROM.
If you whant to improve your battery life try to downlowd from market app "mysettings". That is good app for fast adjusting screen brightnes, turn on/off wifi, gps etc.

Yep she sure is!!
As for the simcard, are you sure it's properly inserted? I never had that issue. Yeah the phone tends to have a little lag here and there, that's where a custom rom will help since they have been optimized further then a stock rom.
As for battery levels there are things you can do to improve battery life.
#1 Don't use the phone
#2 Stop using the phone
#3 Why are you still using the phone?!?
:joke:
Seriously though to improve battery life you could make your emails/weather/news/etc update every few hours rather then minutes, use wifi and 3g only when needed, adjust brightness level, make the screen timeout faster so when your not using it it will shut off, flash custom rom will also help with battery.
I've noticed that screen is the biggest juice drainer and the longer it's on the faster the battery will go. Get CurrentWidget from the market, handy tool for seeing how much your battery is currently being drained.
closed 3g network only 2g network phone
Your battery life will improve drastically in the coming weeks.
Once your battery has been conditioned and the "honeymoon" period ends (2-3 weeks) you should last at least a whole day with medium to high usage.

Root/rom/battery question

Droid incredible. Rooted, virtually every rom through rom manager causes my phone to battery to drain very fast.
After a charge itll drop to 90% in about twenty minutes. Iv heard thats a droid thing.
From that point, it steadies but still is losing juice FAST. Phone has been awake for 8hrs today with light usage and is currently at 70%. Gps off, wifi off, etc. No vibrating feedback, auto brightness.....all settings geared for battery conservation.
Im using Incrom 1.6 with a stock kernal. Any ideas or thoughts are appreciated as i dont stop hearing that everyone in the world is rooted and enjoying their batterys new ability. Ohhh, btw extended battery, red htc one in case that matters.

Try flashing some new kernels..try a couple out. If that doesn't work did you over charge your phone? Or use a car charger?

Its not the battery cause when i revert to stock the battery is normal for what im used to. The change is noticable wen i use any of the custom roms.
Right now wrkng on flash radio, hit a bump waiting for email back.
Ne other suggestions from u or nebody wud be apreciatd
I use the app batterycalibration after flashing new roms it works well for me

Everybody's definition of "light usage" is different. Losing 20% in 8 hours doesn't seem that bad to me unless you litterally never turned your screen on. That said, here are some things you can try:
1. I've found that the auto brightness sucks and I'm better off just manually setting it to 25% or so. That's fine for indoor use and you can't see the screen in bright sunlight anyway regardless of the setting so why bother burning battery trying?
2. Try flashing a kernel that allows you to underclock and undervolt. Perhaps one of Ziggy's nonHAVs kernels (I have found that HAVS kernels to be unstable, but YMMV). Either use the smartass governor or setCPU to cap screen off at 384 MHz.
3. Carry a charger with you
I'd see what is using your battery in settings.
Also, you could try chad's sense (12/28 I think) incredikernel, which sets the max clock speed really low when the screen's off (defaults to smartass governer).
If you wanted to try CM7, gingerbread has a much better battery usage UI that'll give you a nice graph of battery usage vs. time for phone awake time, signal strength, wifi and some other stats.

better battery life

I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing
check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

Mugen 3600mah = better battery life...
Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

G Pro Kitkat Battery hogs

is it just me or is the kitkat ROM really sucks----battery pretty well?
I also notice that the CPU usage does not drop to 20 percent idle but when I used other ROM (JB based) it becomes 5 percent.
RAM usage is good but I think it hogs the CPU. I used cpuz on measuring the cpu usage

Where can I get the JB rom for OGP?
For me, Android was best at JB and went backwards with KK.
Yes, I've noticed absolutely horrible battery life with KK. KK just feels like it is several different parts all just thrown together.
The only reason I think is that theoretically JB uses more battery is that the system uses more voltage than the kitkat. however, what's less voltage use if the CPU is always busy and wakeups are just everywhere.
Hi guys, maybe you could post in some battery stats so we could know more about whats draining your battery in particular and suggest some fixes. I've actually experienced the opposite with kitkat-battery life for me improved. There was even an instance that I got the phone to last 30 hours, with 5 hours, 48 mins. screen. On another instance I got 15 hours life and 5 hours 25 mins screen on. I just lost the screenshots as I had to reflash stock when i was doing some G3 mods., but nevertheless i could post some new ones.
I value batter life was well and i'm curious to see how yours could be improved too..

What a battery life. 15 hours screen time?
how can we accurately measure? because I only use CPU-Z and installed DS battery saver to save power. right now it only used 2% of my battery during the night. (from 1:45 - 5:50am)
I see. can you tell me what app should I use to determine CPU usage of each app/service?

No, my battery lasted 15 hours, and my screen-on time (total time i spent using the phone) was 5+ hours coz i basically used my phone then for gaming the whole day I suggest you download gsam battery monitor app (it also has a temperature_bat. Usage graph), as well as wakelock detector. Another alternative would be better battery stats. What you would need to observe would be the apps and wakelocks draining your battery both when you are using your phone, and also when its idle.
I also notice that battery capacity is 2A in which it should be 3.140A right?
this shows on kitKat but on jellybean, it's 3.140A again.
is there something wrong with the detection of battery capacity?

What happened was that in kitkat, the permisssions required to be able to access battery stat files changed. Thus, apps w/c could freely access the batter stats in JB cannot gain complete access in Kitkat. This is the case for some battery monitor apps w/c now have lesser accuracy in reporting battery. No worries though, as there are means to bypass this problem. If you have xposed you could install a module for this. Also, some apps like gsam battery monitor come with a separate root companion app. Once you install those batter stats will be accurate.
Here's a screenshot of my battery stats for today..might not be 5+ hrs of screen on as i did a lot of rebooting today (themed with g3 tweaksbox). Nevertheless, this is just to show that kitkat has the potential to provide good battery life. Also enclosed is a screenshot of one of the battery apps i use, gsam.
Hey everybody! I have some findings I absolutely must share so you can benefit as well.
I've been doing some tinkering and I've find a way to significantly increase battery life on the OGP.
First thing you'll want to do is put your phone into airplane mode.
Second, turn your screen brightness down as low as it will go. I mean, all of the way down.
Third, don't play any games on your phone.
Try those three tweaks and see what kind of battery improvement you get.

Just so you know, first my cell radio and wifi were both on the whole time. Second, i was on auto brightness the whole time. Third, i played clash of clans as you see in there.
If you have not done this already, adjust your cpu to save your battery juice. Set the cpu governor to powersaver or interactive mode if you just using the phone to send msg and make calls. I let my phone run on msm-dvcs and when I'm not plug in. Check out ROM toolbox if you're rooted. Seriously folks, instead of complaint about how much the roms suck the juice, try these different ways to see they make any difference for you.

[Q] Battery consumption while playing music + charging question

Might seem an odd question, but how much should I expect the battery to drain on the M8 while playing music?
Reason I ask is because I use my phone to help me sleep (brown noise) every night.
I use an app called "Chromadoze" which has been fine for me up until now.
My old Nexus 5, which I partially got rid of because of the battery life, would drain approx 25% in 8 hours using Chromadoze.
However, using the same app on the M8 drains 50% in 8 hours, which seems excessive for a phone touted as having far better battery life (and indeed it normally does under normal use).
Thinking it might be the app, I generated a (59 minute) brown noise file and converted to FLAC and copied to the phone, and set that to play on repeat. This still gave a drain equivalent to 50%. I thought the Snapdragon 801 was mean't to be very economical on the battery for music, but that ain't happening here. I even have the phone in flight mode (as always). The battery stats are telling me that indeed the "music" is to blame.
I'm disappointed with this as I could stream actual music from the cloud all night on the Nexus and get less drain than that.
The other thing thats proved to be disappointing is the time it takes to charge. I have a 2A blackberry charger that I used on my N5 that charged it in just over an hour, but this M8 takes well over 2 hours on the same charger. I realise it has a bigger battery, but its still only 10% difference and it should probably only take an extra 10 minutes or so, not double the time. Can I enable fast charging on this device, after all, the 801 again is supposed to be able to support it.
I am a tad disappointed with my move to the M8 so far because of these issues; it has better battery life overall but these issues make it significantly less useful to me.
I have such an issue with this phone, that whenever I use (so deep sleep isn't allowed) the 50% of the cpu time is always at 1036mhz, which is too much even for listening to music.
Check out by yourself, how the cpu is working, by installing cpu spy (additionally you can install wakelock detector).
If it's the cpu's fault then you may try to set custom settings (max speed) for cpu when the screen is off.
Sent from HTC One m8, or maybe not anymore
Thanks for the reply. I'll check those apps out you recommend.
My next move is to try again with the power saver turned on, and see how it goes, failing that as well, I could try without the boomsound activated, as I'm sure extra EQing will use CPU power.
I hope I can resolve it, as it will be disappointing if not, especially as I really liked the Nexus as a phone but thought this would be a nice upgrade in most respects (bar camera).
I personally think that this power saving mode just sucks, all it does is that it saves data, but not cpu, as it doesn't put apps to sleep, as stamina mode on xperia devices does.
Just make a quick test, turn on your app, then switch to cpu spy, reset the statistics (so you get statistics only while using your app) and turn off the screen and wait few minutes.

When your listening to music at night is your WiFi on and connected?
Ive noticed a strange bug on my device.
When my device is in stand by mode and wifi is connected my CPU usage never drops below 30%. I use SystemPanel Pro to check that.
Now with WiFi off and in stand by mode my CPU usage is between 3-7% with spikes to 10-15% every 20-30 minutes. To me that seems normal.
So if you do have WiFi on while its playing music for those 8 hours test it with WiFi off.
Hi, I would normally use Airplane mode, so no radios at all, unless I wanted to stream from cloud, I've not done that yet since I had the phone, though.
I've just done my first test with CPUspy as suggested, Over 35 minutes it spent 10 minutes @ 1,036 MHz and the remaining time (about 67%) @ 300 MHz.
I'm trying it again with the supposed "Power Saving" function on.
Result with Power Saving on
1,036 MHz - 7:32 - 17%
300 MHz - 24:29 - 57%
Deep sleep - 8:29 - 19%
BUT, i have a feeling the power save mode may have killed it off to go to sleep but I couldn't confirm as it hadn't occurred to me until I had messed about.
So it is slightly better provided it didn't kill the music.
All of this was with a program called "7digital" which appears to be built in. Going to try in PowerAmp next.
PowerAmp seems to look much more economical.
95% (just over an hour) spent @ 300 MHz with just 2:26 spent at 1036 MHz.
Tried my brown noise last night and it drained 34% in 6 hours. Still a pretty poor performance.
Looks like I'm going to have to try and find an alternative way to do this.
I do wonder if the Google play ROM would help as I never had a problem on the nexus 5.
Are those the statistics when your phone hasn't been used at all or was your program running at this time?
If the program wasn't running and you have such a cpu usage then it is probably some deep sleep issue (wakelock detector should help identifying the app responsible for that).
Anyway, just use some app to limit the cpu usage while the screen is off.
This phone likes to be stuck at 1036mhz and for example you could limit it to about 500mhz.
Ps. Power saving mode won't kill these apps, so don't worry.

Those statistics were with the music player 7digital running a brown noise file, but nothing else was being used on the phone.
Later I used PowerAmp which does give a more efficient performance, but sadly, still not good enough really considering my N5 was OK under the circumstances.
I find myself in two minds as to whether to try the GPE ROM anyway, as I don't find the phone as responsive as the N5 either... and maybe it will help with this issue too.

Those statistics were with the music player 7digital running a brown noise file, but nothing else was being used on the phone.
Later I used PowerAmp which does give a more efficient performance, but sadly, still not good enough really considering my N5 was OK under the circumstances.

GPE (and other non-stock based ROMs) will be much faster, that's damn sure, however I don't think this will solve the problem, as HTC one m8 has some weird issue with it's CPU.
I also don't know why it's using this 1036mhz continously, but you can't go below 300mhz if the device is working (like playing music).
Tty to limit your CPU at all the time (not only when the screen is off), that should also save some battery, however the battery life is still nothing considering the one from Xperia Z1.
In case anyone is interested, I did the conversion to GPE. Much better, now feels as fast or faster than my n5, but it now charges much faster and the battery life seems as good as before. Will try and test with some music at some point in the coming week to see if there is any improvement but I have my suspicion that it won't make much difference as I think it could possibly be the more powerful output and boomsound that increases battery drain... But.... We'll see.
Final post from me on this thread.
Its been several weeks now since I've had the GPE firmware installed on my HTC One M8, and I don't regret it one bit.
The battery life is at least as good, but I possibly think better, I'm generally always averaging 4+ SOT, whereas it would be just shy of that with the Sense ROM. The phone is also noticeably quicker at all times...
Finally though, the high battery usage during music IS cured. Using the Chromadoze app I talked about in post #1 results in 20% drain in 8 hours (compared to 50% on a Sense ROM). That is much better. I also no longer wake up to a warm / hot phone. And it charges faster.
So, in summary, the GPE ROM turns the M8 into the phone it should have been since day 1. I just wish it had the Sense camera, but the stock one is perfectly usable.
