What are the best ways to save battery on a zte blade using latest cm7?
Sent from my Blade using XDA App
I would love to know if anyone can describe what their battery life is like. I am using cm7.0.3 and after full charge, on stand by mode I have 80% left after 8 hours. Is it good? Bad? Tips to improve this please!

Tips: amoled therefore use black background
- lower brightness
- disable data connection
- use task killers
I get around a day's use with fairly heavy usage. But games do suck the juice up.
@Drupad yours sounds good, although I'm using N78.
Use Green Power from the Market to turn off Wi-Fi when screens turns off.
Don't overclock.
For my 2¢, I've been using the SMARTASS kernel governor for a while with pretty good results for standby (CyanogenMod settings, Performance, CPU settings).

Hi Oly, Nice to see a familiar name in this forum I was wondering if you are as regular here
If yours is bad - I guess it's because of CM7.0.0 - upgrade it, they have fixed that bug (read on CM7 forums)

My brightness is set to 'auto' - should I stop that?
I don't use data connection for anything other than email sync. However good you mentioned task killer. I have installed advanced task killer and set it to kill all tasks when my screen is off. However, as soon as I activate the phone from sleep mode, I can see at least 8-10 apps already active! - could it be a dodgy task killer?

I get more than a day actually now that I've upgraded to latest nightly CM7. They seem to have fixed to battery drain. I charged my phone last night. I've listened to about 45 minutes of online radio while travelling, made 1 call (about 2 mins) and played angry birds for 10-15 minutes. It's been 9 hours since I first used my phone and I have 53% battery remaining. I am also using a live background with auto-screen brightness.
In a nutshell - I think CM7 N85 is better than N78 - give it a go if you like!
I don't use Wi-Fi. I only use data connection from Orange (they seem to have given me unlimited internet so will get as much as I can - yes because I don't like Orange.)
Overclocking doesnt seem to work on my blade. Anything more than 604 and my phone restarts if I use more than 2 apps!

hi drupad
task killers are different in android apps need to constantly run in the background
its just the way it is (not like WM task manager!) it's normal for the apps to start running again after standby
thanks for pointing out cm7.0.3 changelog thingy! i'll try to reflash to 7.0.3 when im free sometime
unfortunately i'm not as active in SF forums as much... (more in sgs2 + sgt forums)
you should check out the modaco SF forum,! i think it has different roms there!
cheers

I spend almost 3 nights (nearly!) reading Modaco forums, but nothing impressed me as much as CM7! CM7 was the only ROM that had most if not all feature functioning. I am presuming android custom roms have more 'functionality' issues than WM! And if you are going to 7.0.3 - also get nightly 85! It's Gingerbread 2.3.4!

thanks for advice mate
also to my previous question, i have my brightness set to around 50% (not on auto)
also, i advice to use normal wallpapers, not live!
(as pretty as they are, they suck up power!
also drupad, coming from an fellow spb shell winMo fan, you could give SpB Shell 3D a whizz on your SF
i made a thread abt this (tg01 forum) some time back comparing it to spb 3.5 winmo.
it is faster than it was on tg01 and a bit prettier
also it may save some battery.... (if you should, try launcherpro - i think its really good for battery too!)
cheers

Thanks a lot for that advice mate! I had completely forgotten about the SPB Shell! It will be very interesting to see how it integrates to already beautiful android layout! I am going to give it a go straightaway! Will report back soon.. I used launcherpro for a few hours, but soon realised as customizable as it might be, it's only good if I buy a full version (gives more options!) So ended up uninstalling. Won't be spending much on market just yet, may be after a couple of pay days
It's AWESOME! Definitely better than Stock, AWD and LauncherPro! It's sleek and smooth. I like it already.. however, will give it some try in over-all functionality. The app drawer scrolling has improved by 150%... Doesn't lag AT ALL..
Thanks for suggesting this mate.. If the functionality is good for day to day use and if battery drain is minimal, then this is my THE APP!
Already searching for themes and tweaks

yeh it's very smooth somehow! launcher pro / stock app drawer is laggy and choppy to scroll through, but buttery smooth on spb!
new carousel is a nice improvement on the android version compared to wm3.5 right?
it is actually incredibly smooth on SF ! it is also cheaper than WM version..
however, i only use it on my SF, not on my other devices... (some reason it lags a bit on my galaxy tab... )

Kernel governors from my understanding help determine the way the device responds to dynamic frequency scaling.
Performance is the best for device response but consumes the most battery as it's hitting the upper frequency constantly. Powersave is the opposite as it's hitting the lowest clock speed constantly.
Interactive polls cpu demand based on a timer rather than just currant demand (uses a bit more juice than ondemand).
Ondemand gives a good balance between response and battery.
Conservative is similar to ondemand but ramps up/ down to currant demand more smoothly (at the detriment to response).
Smartass governor caps the max sleeping (ie. screen off) frequency to 352Mhz, so uses less battery. However it acts like Interactive when the screen is on & can use more power than ondemand.
For me Smartass works best on my blade, however on my N1 ondemand is better - go figure

Yes 120% smoother and improved carousel! I think they've got it almost right this time.. I've noticed the reduction in SPB widgets though. Thought they might give integration to most of the shell. I wonder what WM users might do without these integrations, widgets. I think buying SF is one of the good decisions I've made this year - it's worth the money for android phone! (Still jealous of your SGS2 though!)

Thanks a lot for that Harmohn, that makes sense now! It's more or less CPU performance profile in a way, right?
Now it makes more sense to put it on SmartAss! It's been working fine so far, but I am not overclocking at all. Will stick to 604, 122 for now and that saves me a bit of battery hopefully!

haha great home screen launcher! Glad to see you have settled in to android very quickly now! you can enjoy thebenifits we never had with the tg01
i second that, zte blade was actrually the thing that led me to android haha... after i bought it, a week later i got my galaxy tab
i was gonna buy that sgs2 the day it was announced in Feb at MWC 11 - glad i did, best thing i ever owned
you should get one mate! Android is the best!
Glad you moved on from Tg01 after orange's bad service!
So i am curious to know does any utility working on Note, that improves performance of Note.
I have installed
1.Set CPU - really i dont find any markable improvement
2.Auto starts - It stops loading some SF on starts definitely, but what? does it has any outcome?
3.RAM manager - My Note have MAY B slight more free RAM, but again does it improve performance?
Really telling i feel all above procedure giving me placebo effect not more than this.
B'coz when i compare it with stock, hardly i can feel difference.
Sure these have marked effect on low capacity RAM devise. when there is consumption of RAM > 80 always remain. But In case of Note, I think it is useless.
Share your review please.

Don't use SetCPU. Your phone will not go to Deep Sleep if you use that app.
Try system tuner pro.

Seriously you don't see the advantage of this?
Not just giving you RAM which benefits are vague. Depending on your use. When the blocked app is not is loaded.
As well as you stop a program from loading, which might ask for sync, wake up the device etc.
Its an alternative to Tits backup Freeze. Except you still can call up on the program with the allowed actions.
I agree it stops loading blocked application, it may released some RAM too. But what i am asking is after releasing of that RAM, does it improves performance?
b'coz Note have alwyas remain 200-300 RAM free, if it is 300-350MB then does it have any outcome? really I dont see.

Did you even read what I wrote .
It stops the program, like the tits freeze. the program won't run.
like for example you stop with this the samsung auto update.
Means it will stop syncing. Eating your battery.
Again saying it. Its like a safer way to freeze an app...
With Autostart you reach better battery stats and lower RAM usage due to blocking/freezing the apps.
They won't start at the beginning and if they aren't loaded, they aren't in the RAM and then you have low RAM usage.
I don't use Set CPU, because the Note is fast enough and doesn't need any overclocking or undervolting.
I use Battery Monitor Widget Pro to see how the stats of my battery are, i can see the full time and when it goes to deep sleep.

No problem here with deep sleep and setcpu.

With my last rooted phone, I diligently went through every single app that started up without my say-so. You can disable every event they respond to. It is a lot of work, but satisfying to the OCD child inside.
There were dozens, all popping up any time they wanted and eating CPU cycles merrily. I did get more RAM and battery doing that. I will do the same when I root this mother.
Setcpu is working beautifully. No issues with deep sleep whatsoever.

It's true, setcpu working perfectly
I use Tegrak Overclock instead of setCPU because it allows me to overclock GPU as well. Overclocking gives me better experience in gaming and smoother interface.
Autostarts gives me better boot times and gives me control over apps. I like apps to run when I want them to run. Why would I need my car fuel management app to run in the background most of the time of I use it once a week? What kind of a dimwit had that idea? It has nothing to do with freezing apps (except that they don't run at boot in both cases).
RAM manager is my favourite snake oil. According to nearly all the experts around it does absolutely nothing except killing my battery. Somehow I like the way it's been kiling my battery for last 2 months and I'll leave it that way. I don't care about the mechanics of it - simply put since I've installed it I experience less laggy moments in UI (ie. when i press my back button 78906 times to go back through several apps) and the effect of my Note getting sluggish after a day of use is gone.
By the way, I've been wondering - if the famous Android memory management is so perfect - why is it being tweaked so much in so many custom ROMs? And this is what RAM manager really is - set of tweaks packaged in a convenient app, not a task killer.

Yet you do the same by throwing out 99.99%... 83% of all statistics are made up on the spot. Lol... I've had instances where SetCPU has crushed my phones battery...3 diff phones. So does that make it 99.98% now?
I use Autostarts religiously. Just becareful disabling system apps.

But this is the very nature of overclocking. When it goes wrong it goes wrong - reboot or pull the battery and choose some other parameters. If it's not OK with you don't do it. Why blame an app which is simply a tool (just one of many, I had the same problem with Tegrak several times)???

Hi i have flashed many nand roms to my hd2 the end result is always the same. phone works fine until i try to play games anywhere between 30s to 10 min and the phone freezes up and is unresponsive. only way to fix is to remove battery. any ideas on what this is why it happens and how to fix it.
what is your ROM? what's your magldr version? what is your HTC HD2 type EU or TMOUS? What is the name of your games? i need more information sir..

I'd hazard a guess at it being an overheating problem. Do you overclock on the ROMs you use? Does the phone get extremely hot? If yes to these, try not overclocking and see if it works.
magldr version is 1.13 and it a tmous hd2 running nexus h2 ics 4.0.4 cm9 hwa v1.2 by tytung. not overclocking running at the standard max of 998Mhz min somewhere around 200. the only option i have used is in the performance settings under memory management i ticked the kenel samepage merging which seems to have reduced the amout of freezing i am experiencing. tried playing the game called drag racing think is by creative mobile. phone on its own works great but even playing angry birds anywhere between 5 to 15min it freezes. noticed yesterday my battery was low so the charge light was flashing and when the screen frooze the light still continued to blink but the phone was totally unresponsive. Any ideas

I have similar problem. But not so often. He is not overclocking, neither do I.
I also use zRam 26%.
This often happens when the phone is under load, so I think that maybe this is due to lack of memory. The phone heats up when the screen freezes.
Any tips?
OK, this might sound stupid but try putting the phone in the fridge for a while to cool it down, then play. Obviously don't do it for too long, it is after all a phone, but I read somewhere that this had helped someone with overheating. I doubt it is a RAM issue cos that wouldn't cause a freeze, it would probably result in the launcher being killed to free up RAM.

not sure putting it in the fridge every time want to play will be quite the fix i am looking for. Might prove the theory that the phone is overheating but then there must be a setting somewhere that can be envoked to get this to stop happening

Yeah I know it isn't a practical solution, I just meant it to test my overheating theory. Perhaps there is a fix, but to be honest if you aren't OCing then I really don't know why it should be heating up so much. Sure, mine gets warm but even when I've played for around an hour on Contract Killer: Zombies (fairly graphically intense and a very fun game) it doesn't shut down or anything. There IS a hardware fix but it's quite dangerous and requires a lot of expertise and the right equipment, neither of which I have Should you wish to try it, just make sure you're very careful
So since I had my nexus 4, I had to complain about its terrible battery life.
I would never get more than 3h of screen on time, despite my best efforts in conserving battery. Even with the phone in flight mode and on Wifi, I could not cross 3h give or take a few minutes. I even tried disabling location, google now, sync and everything else.
It was deep-sleeping nice, while the screen was off, standby time was awesome for me. If I turned it on though, it started to burn through battery insanely quick. So I started monitoring the frequency states with battery spy, and noticed that as if there was a little load, it spiked to 1026MHz and then stayed there for about three seconds every time before falling back to 386 MHz. So I tried setting the max cpufreq to 916Mhz with CPU tuner, and was astonished to find out, that immediately after the load was done, it went back to the lowest frequency. Like it should be, not hanging for multiple seconds on the high step.
Also, If I start CPU tuner, the min freq is always shown as 1026MHz. So I changed min to 386 and max to 916. Afterwards, this stays until I swipe cpu tuner away from the recent apps list. If I start it again, the settings revert. Strange...
With my cpu limited to 916MHz, I get about 5h and 50 min of screen on time without any other measures. Location on, Wifi on, Google now and sync all active. If I just go one step higher and set my max frequency to 1026, the old behavior starts again, and screen time drops to 3h because it seems to be stuck on that freq. Therefore I would like everybody who also has bad screen time to try that out and report back.
I don't really understand why it would take so long to drop back from the 1GHz step, and drop back immediately from the 0,9GHz step?
Of course, this is with normal surfing via chrome, or using normal apps that are not that much CPU intensive. Also, you hardly notice the performance limitation without playing games. There probably is an easy way to fix this?
Feedback would be appreciated. Maybe I see this wrong...
Thanks
tl;dr : if screen on, for me only 1026mhz is used, if max freq is set to anything lower, the phone spends most of the time at the lowest step 386mhz, greatly increasing screen time for me.

Maybe, but I really first wanted to examine out of the box behavior
This is caused by qualcoms Mpdecision which ramps up the cpu to 1ghz on screen on and touches. All in the name of speed. It's basically a hot plugging technique such that smoothness is guaranteed under loaded gui transitions and scrolling. Before this you would have to wait for the cpu to be loaded for it to ramp up speed. Now the OS can demand speed.
You can see in Franco kernel he replaced Mpdecision with an open source alternative and swapped the lowest cpu speed to 368mhz. Then added a load step of 768mhz (for 60% loads). This actually added a bit of lag but should be better in the battery department. Some more tweaking to be done though.
Qualcoms thermald is what is causing thermal throttling.
Edit: this could be wrong. But I think I'm in the general area of what's going on...

This does sound logical, but why the hell waste nearly half of the possible screen time on "perfect smoothness" when even if limited to 0,9ghz everything runs pretty amazing... I will look into francos kernel, even though I dont like to buy an app to tune it,

You don't have to buy an app, everything can be set through scripts. The app just automates the process, allows you to back up kernels, download the latest nightly and milestone (when one becomes available). It's really worth the investment, plus you're helping out a great Dev who has shared his awesome work with us for a long time.

I like my phone to sleep. I bumped it down to 384!
No need to keep it @ the 1.026, it will pretty much kill battery! Makes no sense to me.

You can set the max to 384 mhz.. and still everything is smooth
Can I use SetCPU or is that app defunt now? And to change my CPU speeds can that be done on a phone that's simply rooted or do I need a custom kernel?
EDIT: I downloaded CPU tuner, but I'm not sure if it's working or not. Does it work w/ stock kernel or no?
Faux's Intellidemand fixes pretty much what you're describing. Since mpdecision is not used instead of fauxs alternative.

What is max frequency by default?
Have to say firstly, that the perfect smoothness of this phone is what has sold me on it as the camera is well below average, it has some bugs and the output quality and volume of the audio is shocking, but it is the single smoothest phone out there.
Get rid of what I came to know as Touchboost (feature brought in in jelly bean to introduce the lag free experience of project butter I imagine) from my Sgs3 days, and the phone becomes as laggy as every other android phone out there.
Secondly, I get around 3.5 hours screen on time, without messing about, wifi on constant, depending on whether i'm on the net or not, I can get more.
I find AOKP perfect as its super fast and battery is excellent.
Franko kernel works, but the phone then feels choppy. Setting the cores to 1ghz makes the phone laggy also.
All I can say is, get lots of chargers, I have two at home, two at work, one in the car, one at the other halfs, and it's trickle charging when and if I can and I never worry about battery anyway. I find it wastes far too much life.
Good luck.

Have to say firstly, that the perfect smoothness of this phone is what has sold me on it as the camera is well below average, it has some bugs and the output quality and volume of the audio is shocking, but it is the single smoothest phone out there.

Thank you for not contributing to this thread with that useless comment. The rest of us may not want to charge the phone 1500 times a day (or are even able to), and are looking for ways to help battery discharge go slower while using the phone. If you're fine with charging your phone nonstop, then what are you doing in this thread? Everyone knows you can buy many chargers, that's not a solution.

Welcome to Project Butter. If you want to do something different than Google's goals for UI smoothness and responsiveness, which is what everyone has been complaining about in Android vs iOS, then you'll have to go the custom ROM/kernel route. Thankfully that is easily available to you on this hardware and software platform. Me? I like the N4 just fine the way it is stock.

Dude, this has nothing to do with googles project, but instead with Qualcomms responsivness "fix". Please read the answer to my inital post, and you will understand. Also, the phone does in no way feel choppy if you restict it to .9ghz. Except if you load it so much, that it cant cope with this max frequency. But then again, this is not the issue, but the issue is, that 1026 stays active for to long, so that it burns through your battery. There would be only a small change needed to change this behavior, and "possibly" loosing about a fraction of a second of responsivness, that most of the time you wouldnt even notice... Everybody who tells me he is happy with barely 3h of screen time or even less is just the android equivalent of an isheep, because this is in no way acceptable.

I'm getting around 4-5. Auto brightness, 1 Gmail push, 1 touchdown push, Google now on, HD widgets weather, greader pro syncing, falcon pro syncing, all location services on (I like the monthly reports). Wi-Fi when I can.

What kernel are u using? Im using franco kernel + latest CM 10.1 nightly.
My min CPU speed is 1 GHz and in still getting 4 hours on screen time though. I don't think setting my min at 384 MHz even made much difference in my battery, will try it again soon.

Stock never rooted bootloader still locked.
If you are getting bad battery... simply flash a custom kernel. You get to keep your stock ROM or whatever but you will get substantial benefits. I prefer Trinity Kernel. Only the second or third update on this kernel and now the phone has made huge gains in battery life. Like hfm, I good on screen time... usually 5-5.5. I have auto brightness on, mobile on 100% of the time, and all Google services synced including books, gmail, currents, google now, etc etc. I have locations on, gps on... everything. Sometimes I turn off NFC because I rarely am somewhere where I can use those cool RFID card scanners. What sucks battery is probably a problem in Android 4.2. The phone does not sleep as much as it should. Go ahead and turn all your sync stuff off and keep the screen on static and let the battery die at stock clock speeds. Probably will get at least 5 hours with auto-brightness on. My phone probably sleeps 60% of the time now according to CPU spy when it sits idle in my car for my 8-10 hour work day. I usually get to the car with a bunch of emails, a text or two waiting for me, and the phone has only been asleep the aforementioned 60% and around 90-91% battery life. On a new phone, starting from full charge, this should be at least 95%. My N10 that doesn't have mobile data, only loses about 1% overnight. Apples to oranges but still. I'm convinced that stock voltages on this device are too high, and that Qualcomm did not give Google the latest drivers... maybe because it's not releasable to AOSP as of yet. I really don't know, but it's gotta be something buggy. This SoC is capable of doing better... and it does in the Optimus G and even with sense, 1080p screen, and a 100mah smaller battery the HTC Droid DNA/Butterfly gets 3.5-4 hours stock screen time. None of the other phones using the S4 Pro are running 4.2. I'm hoping either Qualcomm pulls a Samsung and releases some updated drivers/firmware that Google can incorporate or that Google fixes whatever bugs they may have not worked out. In the next calendar year other phones will be out that use the S4 Pro and 4.2 and I doubt Qualcomm wants to lose the luster it earned with the regular S4 Kraits performance/efficiency. When 4.2 comes to other devices we will probably know whether or not Google is to blame for this or that the Nexus 4 is just a poor performer.
Strange as the concept sounds, I get better battery life when I overclock my Epic. At first I thought this was a fluke, since a faster processor (in my head, anyways) HAS to equal more power consumed. Generally speaking, this is true...
But, here's how a higher processor speed actually helps you reduce overall battery life. During daily use, your phone throttles up the processor to get something done, and then goes back to a sleep state. Mine goes from 100 to 400 to 800 to 1100 (my overclocked speed) as I watch it, with my phone just doing it's thing.
The faster it can get a certain thing done (i.e., faster processor), the sooner it can go back to a resting state, which equals more rest and better battery life.
That's it. Of course, this only works for daily use - if you keep it running playing a few games the battery life will most likely be worse. Has anyone else experienced better battery life by overclocking? I'm curious to see if this phenomenon only effects me
My setup:
CM10.1 - Experimental (Jan 20)
NS4G modem, with nitest kernel and patch (Jan 25)
smartassV2 governer/NOOP I/O scheduler
Overclocked to 1100MHz
hmmm interesting thought... i have never overclocked my epic but im just wondering how are your boot times with it overclocked... my daily use on my phone requires bluetooth on all the time and while i am at work i play music and on breaks i play games so i do go through a battery every 2 to 4 hours (I keep 6 spares on hand at all time lol) if it didnt drain battery but sped up boot at battery change would be worth a try just always been scared to oc cause dont want to mess up my phone...
Wow, six batteries? How do you charge them all?
I've been overclocking computers and such ever since I found the clock switch on my old Packard Bell 486. The trick is to not go too crazy and start small. For example, I have two Epics in the house running at 1100, and everything is going smooth. Boot times seem pretty fast, but the overall battery life is better than it's ever been on both.
I tried to clock one of them up to 1200, and I had a couple force closes and a forced reboot, so I backed it down to 1100, and the problems went away. I've heard that others can run at 1200 all day and not have any issues, so it depends on your phone.
I'd like to hear what happens if you do OC yours - my usage is nothing like that!
Sounds about right to me, the cpu isn't working on the same thing for as long and hashes it out quickly so the battery isn't drained as fast.
Just my view, I'm a slightly advanced computer ****.

Definitely dependent on the phone as you said, back in the samurai kernel days my epic could handle 1500 no problem...
I have 2 external charger that came with 3 spare batteries... ebay like 15 bucks or so for 3 and a charger... I may give it a whirl see how it goes... what rom you using now??? Was thinking of just the regular cm10 but I really like the center clock mod of aokp... but thanks for the advice I will let you know how it goes.

Isn't the default lower-bound clock 200mhz on most roms? Maybe the fact that you have it going down to 100 makes a difference too?
^Pretty sure that all ROMs run 100mhz stock.

While the default is 200, 100 and 200 really aren't big enough a difference power wise to make a big jump in battery life...

In the past week, I just upgraded to a Galaxy Nexus, bit still have 2 Epics in the family. One is on CM 10 and tje other is on 10.1. Definitely like to hear how it turns out.
Although this thread is about overclocking, don't ever let your friend that knows how to change the clock speed use your phone. I let my friend use my phone to play a game, and when I got it back, it was really slow, laggy and hot. Because he thought it would be funny to change the max clock speed from 1 Ghz to 200Mhz.
