I haven't ever had FANTASTIC battery life like I'm seeing from some folks around here... when I first started on Starburst (I didn't keep stock for more than about four hours), I was at around 70% at the same time. I'm currently on Calkulin's 2.0.0; about to revert to Starburst and see if it's ROM-related, now that I've given Calkulin's about a week with a calibration to no effect.
I'm currently undervolted by -75 on all steps, and this seems to have made it WORSE if anything, which I didn't think was possible for undervolting to do. I've been monitoring things fairly closely with Watchdog, and nothing jumps out at me. The phone signal in the pic doesn't look good, but I've been in all the same places as I was when I was getting much better life.
What interests me is that I'm seeing absolutely no usage-based change in battery life. Until that sudden dip you see up there, it was going down at the exact same rate whether I was using it or it was sitting on my desk doing absolutely nothing.
That dip started after I played Fieldrunners HD for about ten minutes during a break at work. After I stopped playing, battery life went into a continuous plummet.
I use Tasker (extensively) to keep things in check; generally speaking, nothing is active unless it needs to be, except for Wi-Fi which is always active as it's my primary method of detecting my locations.
Am I missing something simple-stupid here? If not, anyone got any ideas, assuming going back to Starburst doesn't magically fix it?

Not sure if this will help, but improved my battery.
(1) go to your email setting for each account and change sync update, I believe by default it's set up to check every 15 minutes. With 10 email accounts, it took a toll on my my battery. I changed all my accounts to 4 hours.
(2) best way to kill a task is by holding down home button, going to task manager and kill from there. Market task killers were making things worse for me.
Hope this helps.

Thanks for the thoughts! Sadly, neither of those really apply in my case. I stick with with the default Gmail app, which is all push, and I don't use task killers at all.

I'm running the stock rom with a custom kernel. I did notice that as soon as I went from stock to a different kernel I started to lose battery life. Maybe its something Samsung did? I am still a novice with Roms and what not, but nothing like this happened on my original Epic or my Hero. Maybe the yellow triangle isn't the only thing Samsung put in there.

Maybe the aggressive undervolt is causing your phone to ramp up to a higher state to perform the tasks? That drop is steep with how little screen on time you have

For as little as I know, that certainly sounds logical. I still wasn't getting as good as I would've expected even the UV, though.
I just flashed the EK02 modem with today's wonderful developments; I'm going to wait and see if that gets me better reception and thus better life. If not... now I'm not sure whether to try the new ROM first, or scale back the UVs. I want to try one thing at a time, since it's not urgent that I have good battery life ASAP. This gets me through my day, currently, more or less; I'd like to try and find my root cause so that I'm not just trying things wildly in the future.

Well, the good thing is that as of today, its possible to return back to bone stock and start again so you can mess with a few setups and see what works best for you. I have found that this is the first phone that uses the frequencies well. I haven't undervolted at all yet and I have had great battery life. I did the standard delete Sprint bloat, Social Hub and associated apps, Maps, etc. Also, get BetterBatteryStats. It may give you some insight into what's happening.

How you return to bone stock? By applying the update?

Then update to EK02

Got very slightly better today after flashing the EK02 kernel. 23% at the same time instead of 18%... anything could account for that 5%, though, so I don't really think EK02 had any effect on this. Zedomax kernel with stock voltages is next.

CPU boots pro
(From the market & assuming your rooted)
Settings
~Screen off profile max800 min200
~GPU to Conservative max1000 min800
~Nitrous Widget GPU to on demand max1400 min1000
What this should do is downclock your device when on standby by alot. Second for phone calls and daily stuff a clock of 1k will be silky smooth and be a small downclock. Third when you set up the nitrous widget and activate it you will overclock to 1.4k which is stoopid fast my quad score is at 1.4k I get 4500 scores at 1.6k oc but forget batt when I'm using the nitrous. I like too personally keep my phone at a clock of 800 for daily phone calls and web surfing... if I play a graphic intense game ill oc it with nitrous and not worry about burning up my phone because if I set the phone down it downclocks as soon as it stands by and will pick right back up when I'm ready.
Hope it helps here's pics.

If you're talking about the page I think you are, it'll have to wait until at least morning. I just did a full charge.
To wit... I spent 43 minutes on a phone call, and lost almost the same as what I normally lose in that same time period. 6% for a 43 minute call; I'm averaging 5%/hr loss doing NOTHING.
@Dchibro, assuming that's true, what would it mean for me? Does it give me a solution?

So, doing a bit of my own detective work... I've had Watchdog installed for about three days, with aggressive monitoring. I was almost immediately getting a bunch of alerts for two processes:
I initially whitelisted them through Watchdog, dismissing them as system processes that unavoidably needed to run. However, the comment from Dchibro got me thinking and sent me back to those, and I started Googling around. Here's what I've turned up so far:
http://goo.gl/Hsvej (HUGE thread on the issue in SGS2 forums. Haven't had a chance to go through all this yet.)
http://goo.gl/kUcqx (SGS2 forums.)
http://goo.gl/mlWW4 (Nook Color forums.)
http://goo.gl/mNiId (My Google search results.)
Gonna try some of the suggestions on here and see what I turn up. For now, I'm returning to stock voltages, implementing a bunch of those changes and keeping everything else as it is now to see where I end up. Phone will be charged to 100% before bed tonight, and I'll post sometime tomorrow with my findings.
Wish me luck!

So, in stead of waking up to 50% this morning, I woke up to 86%! Which is the same I went to bed at. Six hours of sleep, not a single percent lost. If nothing else, I learned from all this that I can reboot the phone when this bug hits me and and get away from it.

As I suspected. Your Watchdog shot clearly shows that you are/were (sounds like a reboot solved your issue at least temporarily) suffering from the Android OS bug. This bug presents itself most prominently in the suspend and events/0 processes. Unfortunately, a conclusive solution has not been found, but there are some things you can do to hunt the problem down.

Im one week into my new sgs2 running full stock. What should normal battery use be? I feel my battery drains too fast. Here is my usage summary since full charge couple hours ago.
I charged too 100%, shutdown, then charged to 100%, powered up and used the phone very sparingly since. Battery is at 91%

Definitely seeing a bit of an improvement, here.
Watchdog alerted me to the suspend and event/0 stuff again about an hour ago, but I quickly rebooted and nothing seems to have come of it. I'm going to try to make a Tasker profile to do this automatically, kinda like Viper's LoS script.
All in all, I'm considering this a mostly satisfactory alternative to draining 80% of my battery with almost no use in eight hours.

Comments on p6 huawei ascend after a day of use

Yesterday I bought a Huawei ascend p6 for my wife. Even when holding it in hand, I feel like its design. After a day of use, I feel quite disappointed in its performance. When running the game like candy crush, subway surf, ... I find it does not run smoothly, or say exactly shocked. I wondered if I run the game require higher configuration will how?
According to you, is caused by the configuration of the machine or the rom? Is there any way to solve this problem?

U can try to run it in performance mode.

The cpu and GPU locked in a certain frequency power can be achieved not so serious and fluent game approach.
The first machine to ROOT then RE Manager to set inside the file!
1. Open sys-devices-system-cpu-cpu0-cpufreq-cpuinfo_block_freq, use a text editor to open, modify the value of 600,000 or 800,000 or 700,000 are cpu frequency is locked, save and exit after completion of editing,
2. Locate scaling_cpu_lock_nun, a method using phase inside the 0 modified to 4. It is locked cpu cores. Save and exit editing can! In power management policy settings in a super-power standby.
GPU in accordance with slim post to unlock! But I set 480000 360000.
Heat is also not so great to play the game is very smooth! Power consumption is not serious enough for everyday use heat is also better!
I charge 100% after setting the screen brightness is not open to the minimum WIFI playing whitewater boats two effects 30 minutes of high power consumption 23% is power! But look at the beep beep miles 720 miles to see 24 minutes of animation power at about 7%! Several times hovering at about 7%.

Hi there, im not very code technical, From what I can see, have you made the phone not get as hot and gave it better proformance, the only thing thats putting me off buying this phone is that even though it has a snapdragon S4 pro it isnt as good as the Nexus 4 which is cheaper and that it gets way to hot ( someone had a screen shot of the phone getting so hot that asked to close apps )
Many thanks

well... Based on what I know about this phone, the CPU is not a Snapdragon S4 pro but a K3V2E developed by Huawei itself. That might explains the performance issue. Huawei locked the CPU frequency and GPU frequency for power saving reasons, but it locked it too much.

No way! How could they lie? Do you think its a Cortex A7? I only ask because the battery life seems pretty good and as far as i know 1.5ghz is the max an A7 can go, also if the performance isnt great, that would be why?

Hi
Im satisfied with my new P6, but honestly the battery life is very bad. My phone 's been 5 hours on battery, and has 50%. I have disabled Google services, wifi, gps and cleaned background apps. I dont even keep my screen brightness high !
I also get sometimes mobile data lost, i've 3g/h on statusbar, but data is not moving. Going to airplane mode and back makes it work again. This happens few times a day.
I have B106, the build which came with the phone. Should i update to B107 or something else? Im in Finland with Elisa / Saunalahti network and i've heard about connection issues on B107. Is it still better than 106, or is there some other build that i should try?
And have you any info about coming versions from Huawei? Thanks alot

We have in Germany by default B104 and the B107 is much better ... at the moment I have a beta B111 on my phone and that is still better than B107 ... I think there will be better roms soon.
Hope that there will be custom rom possible soon, the test possibility is much better then ...

Find out whats causing the drain. Go to settings-battery(asetukset-akku) and see if there is a program misbehaving. Stopwatch prevents the phone from going to deep sleep and therefore drains lots of power even when the screens off, other programs might do it aswell.
If you get 4-7 hours of screen on time id say that its pretty normal, although i do not play any games that consume loads of power. And i think browsing with wifi consumes less power than mobile data.
Ill try to take some battery stats with syncs, gps and google now on. So youll have something to compare with.

Nexus 5X performance issues, compared to Nexus 5

Hello everyone.
Yesterday I bought a new Nexus 5X, been using Nexus 5 for the past year.
While setting it up, and later using it I started to notice small hangs in performance, simply it kinda wasn't as snappy as I expected coming from two year older phone, it's older brother.
I did Antutu and Geekbench tests, and both gave 5X a lower score, and here is geekbench comparison (to my N5 with ElementalX kernel at 2.5GHz): http://browser.primatelabs.com/geekbench3/compare/7158323?baseline=7158280
Simply, Nexus 5 blows it away in many aspects, including the average (total) score.
Are there any workarounds to this? Overall, I am satisfied, but not as much I hoped I would be.
What are your experiences?
Is it worth rooting and trying other kernels? I would like to keep it stock as much as I can.

Did you try updating the OS the MHC19J or newer? The encrypted user partition is significantly slower prior to MHC19J.
Did you try setting it up without migrating google account data (ie set it up as a new phone)?
Also try to keep 15% free space unused. On my past phones, EMMCs started performing very poorly when they got close to being full.

Thanks for your reply!
It's on MTC19V build, I updated it as soon as I started it first time.
Firstly I did set it up as a new phone and it was as slow, later I reset and migrated data from N5 because I wanted to save some time from setting everything up again.
More than 50% is free now, still haven't copied any music or movies since I have no USB-C to USB-A cable.

Either encrypt your N5, or decrypt your N5X.
Then you'll have true conditions to compare the two, since the forced encryption on 5X makes it laggy.

I could do it, but I still think this problem is caused by something else. I doubt all the people on YouTube for example, who compared them gone that far because that is not how it should be used...

also, be assured that the encryption barely makes a difference on the 5X at all. if you notice lagginess, it's more likely due to an app hogging resources.

I don't know for sure, those are all apps I had on my N5, minus few of them.
Will see how it goes in next few days...

Well the MTC19V build would have addressed any encryption vs decryption issues, so personally I wouldn't bother going through the effort to decrypt.
You aren't running out of space so it isn't an issue with EMMC wear-leveling not having enough space.
You installed as empty phone and it was still slow so it wasn't migration of data.
So I don't really have an explanation for why your phone feels slow. It doesn't feel slow to me, but perhaps this is a perception issue.
I would feel it was slow if it took a long time to load stuff or there was janking and stuttering performance. For my usage it is very smooth.

Do as the above poster suggested, decrypt. I agree that encryption on the 5x causes lag. I can compare apples to apples as much as possible, both my 5x and N5 are decrypted, both on Chroma and both using Franco kernels; both are very smooth in this set up.

So, this weird thing happen... I don't remember doing anything which could directly improve performance but this whole day the phone was simply flying, very fast!
Installed geekbench once again and did the test, and this happen: http://browser.primatelabs.com/geekbench3/7174524
Almost twice the single core score, and much higher multi core! How? I have no idea.
Still not rooted, which means absolutely stock and encrypted. Just weird if you ask me... I hope it stays like this!

Sometimes I've found during initial set up there can be maintenance operations going on in the background that aren't always obvious. Once it all settles down, the phone goes back to normal performance.

You'd be surprised. Google has all sorts of these delayed processing algorithms so everyone isn't doing the same thing at the same time.
I had 2 5x units side-by-side on Project Fi. One had a particular phone app version that was totally different release track from the other. I would log into Play and try to download the same version but the one phone was just stuck on its release track. Then 1 day later, that older release decides it is time to update Google Play Services and the Phone App, but the first phone doesn't see the Google Play Services update for 3 more days.
Then my phone starts feeling kind of slow and after some investigation, I notice it is downloading an OTA update, but I didn't see it at first because I got tired of seeing OTA notifications so I blocked notifications for Google Services Framework. I didn't consider this a general slowdown for the 5x because it really was doing something in the background, I just didn't realize it.
These might not be what your experiencing, but next time it slows down, run a process monitor, logcat or dmesg to see if that gives clues what might be going on.

After some more use I realized my problems were actually 100% caused by heat.
I guess CPU throttled down that much, it caused stutters and lower scores.
Realized that while playing a game, and after around 5 minutes of constant load, game suddenly slowed down and fps dropped at least in half.
After that I run geekbench, once again, while phone was still hot and as expected scores were painfully low.
Let the phone cool down for half an hour, without restart or swiping out recent apps, and ran benchmark again. This time, cold phone, and results were back to normal.
Repeated the test two more times, and results were exactly the same, higher the temperature, lower the performance, as expected.
The question is, could new kernel help in this case? I've used elementalX on the Nexus 5 and it had throttling settings. Also, I had no similar issues on N5, even though it was slightly overclocked.
Advices?

Temperatures went up to 60C degrees when I checked in CPU-Z after closing the game.
Not so sure about frequency since it dropped all the way down on first 4 cores because of low activity.

Looks like he's checking his CPU core temperatures, but at 43C I'm guessing you're talking about battery temperature.

phone sudden heat spikes..

my phone is working as usual , the temperatures are well within range, playing an online game in 4g at a temp around 30 degree Celcius, gets my phone to around 37-39 degree Celcius in sensors in CPUZ and msm_therm goes around 39.
but now for these 2 days, my phone just by unlocking or browsing gets sudden heat spikes like sensors go 55-60s and msm goes till 48.. but sometime afterthat, it behaves normally as if nothing happened.. what is really happening. i have no clue.cleared cache and all.
Update: i locked my phone clearing all my apps, after few minutes it returned to room temp, but again, reamining locked, my phones temps was kinda hot, when i unlocked it and checked, the temps were spiking around55-62 in sensors, and 44-45 in msm_therm.
what should I do?

I don't know If it's the same problem, but yesterday i was about to grab my phone, it was really hot. Maybe beyond 60 celcius. I quickly checked battery stats. The system was eating an enormous amount of power (1000mah) (see attached pictures) , I rebooted and it's all normal now. [Nougat] [OOS4] [Experience Rom 5.0]

I was playing clash royale in 4g with surrounding temperature around 27C. the CPU was near 35-36.
and i locked the phone. 5 minutes after i unlock it the phone is hot, without any usage, temperature in sensors spiking around50s and 60s as mentioned above, msm more than 45

In my case I just cleared cache in recovery. It solved my problem.

Have you guys checked if pocket mode is enabled? That is the only explanation I can find right now for heating up when locked.

i did it twice, and mine is kinda good in safe mode for a day i guess, i switch back on to normal mode, heats spiking up, even when switching of dataLTE... rebooted many times.. donno what's the issues and i definitely not an hardware issue i guess, coz it was good in safe mode

it is enabled and the issue is not when it's in pockt, when it's placed on table or any surface

Run 'top' command in a terminal app (I.e. Termux), when you get heat spikes, to see what process has high cpu utilization.

i quite can't understand this, but this was the scenario... the mobile stays cool , the moment i unlock it starts it heating..
and attached the temperatures too without any activities itself.

Does your big cluster go crazy? I've had that. I flashed back to 3.2.8 if the issue persisted (clean) it didn't so I flashed back cleanly and it was fine.

Well let's see where the heat comes from, what does your big cluster do? Does it run on high frequency for no reason? Then do what I suggested what I did, but dont do things blindly let's first diagnose if the big cluster is the issue.

Oh well, your phones CPU the SD820 has 4 cores, 2 big ones (peformance) 2 small ones (efficiency). Can you download CPU-Z from the PlayStore, and see if the big cluster (the bottom 2 cores) are running on a high frequency even if you do not touch the screen?

Oke, I had that as well on Beta 10. After flashing 3.2.8 (full zip) then flash Beta 10 (fullzip) again it works fine, are you on stock recovery or TWRP?

Oke try to reflash any rom . If that doesn't work your going to need TWRP but I doubt it will come this far. I do recommend a clean reset!

Thank you very much... re-falsh should i re-flash the same or should i try hard restting once ?? and it'd not a hardware issue right... coz i'm really worried/...

It's not a hardware issue . Because if something was damaged your phone would simply not function. I'm not sure how stock recovery updates your phone, but a hard reset (I think) should work and otherwise you can just reflash full zip of 3.2.8 here > http://downloads.oneplus.net/oneplus-3/oneplus_3_oxygenos_3.2.8/

16 day battery life

Hi guys.
I am trying to find out what everything can be turned off keep basic phone functionality to reach battery life that this phone deserves with nearly 5000 mah battery.
Curently i downclocked gpu turned all cores except one core limited to 400 mhz (with free kernel auditor in store).
phone is bit lazy ( like old android phones but still usable for basic functionality like picking a call or responding to sms)
but every time i need reasonable work i enable 2 big cores. with just 2 taps and when done turn them off.
As for services i disabled pretty much everything and left only minimum 7 services running as seen on screenshots. also do not disable location services or phone will not boot. killing them after boot is enough it seems.
I enable google play services + play store + download manager just when i need to download/update some app and disable them afterwards
for fast enabling/disabling most used services i use free package disabler from store and keep them in his favorites. too bad his widgets dont work on my device. also it doesnt stop services after disabling so i stop them wih force stop helper.
in developer options i disabled background services and enabled gpu acceleration for 2d.
this is second time i am trying to reach 16 days and I am in the middle.
what would elevate battery life for a little bit longer is if I guess if I can lets say each 9min be on airplane mode with 1 min airplane off to catch missed calls sms.
i remember i did pulse airplane mode from cron with script and build in utils but i guess that would require cron running in background whole time which i dont like.
Is it possible to launch timed events based on hw timer without having an app running?
I love cpu tuner that has exactly that airplane pulsing but each time it pulses it crashes. if i only knew why.
Also is it possible to find out what service on folowing screenshots eaten how much cpu and why ?
thx guys. hopefully i will reach more than 16 days with your help.

I just have one question... Why? This phone already has an amazing battery. Why kill functionality for a marginal increase in battery?

I am not sure I would call2 days fantastic battery life. Also I dont think I sacrificed that many functionality. If i need camera i enable it in one tap i need play store i enable it etc.
Now is this litle incovenience worth aditional 13 days for me definitely yes.
also how come phone lasts 2 days before and 16 days after ? this is definitely waste and governors are not equal to core shutdowns i guess
After some time when i will reach maximum . lets say 20 days ?
Only then I will start reenabling minimum common sense features like pulse wifi and email at specific intervals.
In the end when I will have more clear idea what services are draining battery unnecessarily I will try to code something that pulses wifi plus disables cores/services when screen is off.

I don't understand you, what’s the problem by charging it every 2 days and no need to limit it.I prefer it fast and no missing any call or sms,I've just frezzed some apps that I use rarely and others to stay active in background.

The OP clearly has a project where he wants to maximize every joule of energy available to him - which is a very noble endeavor. We live in societies which are all too happy to waste the resources available to them - the case in point here is that we have two posters quoted above who think that wasting energy is somehow acceptable - and charging up the device more than necessary is perfectly fine.
Whatever the reason the OP has decided to pursue this endeavor, it is in the spirit of XDA that we encourage and help, if we can. It is not for us to batter the aspirations of another member, purely because we don't understand the motives of their pursuit. This is a community and the only way it will thrive is if we encourage the curiosity and passion that has driven us so far.

You may be right but from my point of view what for I need a movil phone if I can't receive a call or a sms at the moment?By removing the Sim, without using any app and turning off data and wifi you can get too about a week without charging but then it has no sense.

I think enabling 2 big cores is unnecessary for your purposes, just allow the small cores to clock up to 0.8-1ghz when you need work done. If your phone is 'lazy' with 1 core clocked @400mhz you're wasting screen on power whilst waiting for the 400mhz to do its thing.

Updates?

Thx panyan for warm support. I also think that xda is fantastic place for all kinds of tinkerers and experimenters. who knows where most modern software in mobile phones would be if we had not places to evolve like XDA, a lot of features that are now in android or ios were firsp created and popularized by comunity as mods first. or firmwares that would not exist for older phones otherwise.

You are right. Thats great idea hopefully governor will be as efficient as manual throttling. Will definitely try that.
not much progress thou ;( can't push past 16th day.
Biggest drain right now is phone idle. are you guys aware of way to have finer power usage log ? ie what exactly is eating that cpu ?
Or mayby broadband chip is thirsty when sihnal is weak.
mayby airplane on for 5 mins when signal is weak would help. but right now I have not idea where the power is sinking. I am allready on 2g so maybe some 2g parameters to tinker with ?

currently I am getting 20~24 days of stand by time with network on, wifi off, no data. although I use the phone only as a back up and rarely use it. So the insane standby is expected
