Hey guys,
I need help. My battery life is absolutely shocking. And yes, I have adequately calibrated my battery (which IMO shouldn't make that much of a difference).
Please share your tips for maximizing battery here!
Basically, when I call someone, I lose like 10% in about 10 minutes. Not good. And I like to be on the phone for hours on end.
Please help, and thus also help others!
P.S: I am using Wolfbreaks 2.3.3 ROM.
P.P.S: I have tried:
CPU Profiles
Setting Max Clock Speed to 576MHz.
Governor is interactive.
2G only (never 3G) on a 900MHz network.
Manually killed some tasks which may consume battery (rarely though, makes no observable difference).
I never connect wireless, and (background) data is disabled.
Brightness always at an all-time low.
Added some build.prop modifications (setting the WiFi scan interval to 5 minutes [300 seconds], just in case I enable WiFi).
No Bravia Engine/xLoud enabled (not even included in the ROM).
Undervolt kernel module (my phone never crashes).
NOTE: Aeroplane mode is not an option unfortunately I need my phone on an connected 24/7.
Other things to note about my use:
I don't ever listen to music.
I never browse the internet whilst connected to 3G.
I rarely connect to my WAP.
I rarely use the camera.
I rarely watch videos.
I occasionally (sometimes) browse the Gallery ( <100 pictures ).
Cheers guys!
Even I have recently installed wolf's rom and I find that the battery is performing lesser than before...
Did your battery encounter overheating issue before? I'm not an expert therefore I'm just capable to give advice As for me battery draining quite fast too when on call but on other time its just fine

Has anyone hit an issue whereby battery drain is high on a particular wifi network.
In my case this is a busy (1000s systems in subnet) corporate wlan running EAP-TLS. Many access points.
At home (using speedmod and siyah kernels) battery life is excellent.
But in the office when this occurs battery drain occurs at a similar rate to web browsing. System is not sleeping as much as usual, and it's not all 200 Mhz running either.
Not yet been able to pin down the behaviour, though it occurs with pretty much all user application processes killed (frozen). Disabling wlan puts usage back to normal, re-enabling wlan hits the issue again. going home (no reboot) and onto my home wlan results in normal battery again with high % sleep.
I'm guessing it relates to traffic on the wlan - maybe lots of broadcasts, maybe re-authentication issues.
So has anyone found issues with battery drain in busy WLANs?
Running rom KJ3
May have to get into tracing/wireshark etc to figure this one out...
Hello, everybody. Newb here (only have had the HTC Evo View 4G for a couple of days now). I have a question about the battery and screen. Is it regular for the screen to use up about ~60 percent of the battery? (According the usage stats). I find that the screen is bright, even on the lowest setting.
Also, I have a question about the battery. It seems to be draining a little quick (I am using lowest brightness and WiFi only). Could some people share how long their battery usually lasts for regular usage? I don't think it's a hardware issue. Like I've said, I've only had it for 2 days, so I don't know if I still need to wait a little.
Thanks!
The screen is one of the biggest battery drainers (if not the biggest) on tablets. So if you are using the tablet a lot, and the screen is on for long periods of time, then 60% seems normal. I don't have my Flyer with me right now to check what my % for screen is.
Battery drain is going to depend a bunch on how much you are using your View, and for what. With moderate usage, I can get around 2 days on a charge. I'd say that is about average for me. But if you are downloading big files and gaming, and/or have the screen on a lot, it can be significantly less.

Okay, that makes sense. The battery life seems to be getting better. One more question. I want WiFi to turn off after a certain amount of time once the screen timeouts. Is there any way to do this in the settings or with an app? The settings (official 3.2) has a WiFi timeout policy that gives three options:
Switch from WiFi to mobile data when screen is off
Never switch WiFi off
Never switch WiFi off when plugged in
I live in Canada and don't have a plan. Would using the first option drain more battery because it is looking for a connection? Or should I use the third option?
Thanks again.
Hmm, not sure. I have the WiFi only version of the Flyer, and on mine the first choice is just "When screen turns off". The first choice on your View is weird. Mobile data always uses more power than WiFi, if both are available. I don't see why you would ever want that.
BTW, I'm at home and have access to my Flyer now. Battery usage for screen is 52% for me. So I'd say 60% you mentioned is pretty normal.
You should also take into account, unless you've taken steps to turn it off/remove it, Cell standby might also be causing your battery life to take a hit. Since the View is set up to also be able to receive text messages, out of the box it's constantly trying to connect to Sprint's cellular network, even if you have mobile data turned off. This thread discusses ways to deal with it. Cell standby used to be one of the biggest users of my battery. Now, it's no longer a problem and I've seen a major increase in battery life.
As for the WiFi issue, the first choice in the settings actually says "When screen turns off (uses more mobile data)." That doesn't mean that it automatically switches mobile data on if you've turned it off in the settings by selecting that option. It's worded that way because the View is designed to be used on Sprint's network, so under normal circumstances it is assumed that if you turn WiFi off, you'll have a data plan and automatically connect to the mobile data network. If you don't have an account with mobile data from Sprint, and you've turned off mobile data in the settings, it won't be an issue because you have nothing to connect to.

Okay, thanks everybody. I really appreciate it. With heavy usage (basically using it all the time) I'd get about 6 hours and 10 minutes. Is that normal for everybody else?
Also, I have a couple of more questions, if you guys don't mind.
First of all, could rooting my device boost my battery life? Would it give me more access to settings like screen brightness?
And, do apps running in the background use battery life or are they 'frozen' until active? This sort of leads me into my next question. Is having 400-500MB of RAM always being used normal? Is the OS using all of it?
And I notice that when I put my tablet in airplane mode (to kill the 4G radio) I lose access to Bluetooth. Is this normal and will turning off airplane mode for a minute be a battery drain?
Thanks again, guys.

Answers:
Rooting won't necessarily boost battery life, but does give you ways to access more system items if you want using apps that take advantage of root.
Android attempts to keep non-rumming apps in memory so that it can load them faster in the future (Ram is much faster than SD memory). 80% Ram full is typical.
Airplane mode turns off all radios, BT, Wifi, GPS, 3g.
There are apps in the market that can turn various things on / off based on your environment / time / conditions

You don't need root access to adjust screen brightness. Settings -> Screen -> Brightness.

Airplane mode turns off all radios initially, but then you can turn almost all of them right back on (except for the cellular radios). I run mine in airplane mode all the time to keep the cellular radio completely inactive, but I still use WiFi, GPS, and Bluetooth when I need/want them, and they all work great. Are you running Gingerbread or Honeycomb? I do seem to remember some mentions of not being able to use Bluetooth in airplane mode on Gingerbread. It works perfectly fine on Honeycomb.
And you can turn off the 4G radio and all data service without turning on airplane mode (Settings -> Wireless & networks -> Mobile network). Doing this turns off all radios that receive data from the cellular network, but it doesn't turn all cellular functions off since the View is also set up to receive text messages. That's what airplane mode or any of these options address.
What I meant by adjusting the screen brightness was being able to control its range more than I can right now (I feel that even the lowest setting can be too much). But it seems that rooting/installing a custom ROM wouldn't do too much for the battery.
But my issue with airplane mode is that I can't turn on Bluetooth with it (Bluetooth is 'grayed out'). I am running official Honeycomb.

Did you try tapping on the box for Bluetooth in the settings even though it looks like you can't, and did you try using a widget to turn it on? I'm using stock OTA Honeycomb, and Bluetooth works perfectly fine for me while in airplane mode. I can turn it on in the settings (the box does look a little "grayed out," but you can still select it) or via a homescreen widget. If you can't turn it on with either of those, then it would seem that you've got some other type of problem. It works fine for me. I just tested it out again.

I just tried it. It seems to not be working for me, but it doesn't seem like a glitch but something built into the OS (I tried with a widget and it did a little 'no' animation). It's alright, I rarely use Bluetooth anyway.
Thanks for all of your help (plus everybody else, too)!

I'd venture to say it's not something built into the OS. If it is built into the OS, then there's a glitch that allows me to use it under the same circumstances, and glitches rarely enable functionality. They almost always cause a device to lose functionality like you're experiencing. I'd be curious to know if anyone else is having the same issue you're having.
Last time I have ran battery test on my Flyer I ran it for almost 11 days on one charge. Yeap, 11 days. I mostly used Flyer as a notepad, checked orders on website couple of times a day, read emails. One day I played a game for about 20 minutes. At the end I set up and tested Plex and Google Music. I stopped the test at 11% charge. Overall screen was on for a bit over 4 hours (40%). Wi-fi on for 16 hours (only 4% ??) according to stats. That's pretty much it. Tablet idle 43%. Fairly light usage, but I mostly was testing how much of useable time I can get out of it. 11 days is a pleasing result.
in my quest to get a better battery life out of my phone (seen people saying 2 days battery life) i have tried 6-8 roms, 3 kernels and 5 modems. all of which give me less then 10-14hrs usage (i know thats fairly average for some of us)
IS there an app that can change cpu speeds based on what app is on the foreground?
my regular usage is:
1200mhz,
ondemand,
3g enabled all time,
~40mins talk time
~100sms
~45mins gaming/video (for train journey =D)
~5mins gps (to check for my bus home)
Push exchange emails
auto brightness
haptic feedback
Tablet-Mode
I have tested that for 70% of my daily usage this works fine for me:
500mhz,
lulzactive,
3g enabled all time,
manual exchange mail sync
but in testing games such as temple run i would need max 1ghz
(have yet to test with music yet... 720p video runs fine @ 800mhz and 1080p @ 1ghz)
i have seen there is a way to inject 3g to 2g toggle when screen is off, is there any way to do it without injecting into the zip? or inject directly into rom?
i think then i could run push emails without much problem. then my phone will really be ON DEMAND!
during 500mhz i notice a slight reduction in battery consumption (not as much as i thought however)
i am running D4ROM v10 with siyahkernel 3.1.2 with resurrection remix as dual booted rom. will prob be getting the 1900mah anker battery heard its decent and fits in normal cover, so yes please let me know if you do get longer then a day, and also if what i need is available (i have searched)
There is no need for such applications mate because android by itself handles the load balancing. The load increase/decrease is basically dynamic and hence you cant predict that.
Overriding that will only consume more battery.
well from the last 2 years of using android underclocking has always increased my battery quite a bit... even right now its consuming 2-3%/hr compared to 5/6% from 500mhz and 1200mhz in sleep, at the end it adds up!
I imagine Tasker could achieve your odd request, though I haven't checked.

I have got the tasker 7 day trial and i can honestly say it is amazing! takes android to a whole new level!
got 2g and underclock & screent timeout 20secs when screen off, then when i use dolphin it connects to 3g, when i play games it clocks to 1ghz 10mins screen timeout. when i plug in OTG usb stick it opens mx video player !
only problem i have is when the screen times out it underclocks (say if ive opened a game) then when i wake the device and unlock again, - the profile says it should clock to 1ghz... but it is staying at 800mhz (which is the screen off max clock speed...) - temporarily just pressing home going to recent apps and opening the game again
p.s. using around 2-3% on sleep/hr and 4-5%/hr with moderate usage (few texts, browsing, play store)
Hi guys,
I asked a few days ago about governor settings but then set out to explore it myself. The aim of what I was doing was to make my truesmart last a full day of normal use. I am trying to make my truesmart my primary device, so a full days use is important (especially as Omate have not yet shipped my second cradle!)
Over my first couple of days with the Truesmart it was lasting about 9 hours of moderate use (Moderate use to me is having it on my wrist all day, showing people who ask, talking to my girlfriend on hangouts, checking facebook and updating a few apps). This meant that it was usually running out of juice on the walk home from work. And that really was not good enough. Yesterday, with all my modifications I was able to go out until midnight, and come home to 40% battery. So these are the tools that after trying a few I think are worthwhile.
1. Bluetooth on call https://play.google.com/store/apps/details?id=com.futonredemption.jasper.btoncall
Does what it says, when someone calls BT turns on, pairs with my headset and lets me pick up. In reverse I dail a number, count to 3 and select the bluetooth speaker, usually before they have picked up. The result is that BT goes from being about 17% of a days charge to not registering on my battery meter.
2. Lean data - https://play.google.com/store/apps/details?id=com.teqtic.leandata
Wifi is on when screen is on or on charge, when screen is off it can be set to pulse on and off for set time periods (i set 1 on and 10 off). The result is that Wifi goes from being 20% of a days charge to being about 4%
So once I was done with the two most obvious methods I had two main culprits of power usage.Cell Standby (41%) and Phone Idle (37%). Short of some baseband tuning 2g off (I live in Korea, there is no 2g) there is nothing that can be done with cell standby. So I looked to governor settings to reduce Cell standby and maybe even improved on screen battery performance. I tried a few apps, but this was by far the best
3. CPU tuner - https://play.google.com/store/apps/details?id=ch.amana.android.cputuner
Usual warnings here, this app is playing with some fairly low level stuff, it may stuff up your device and it does have a few bugs.
This app actually makes the first two redundant,, I've left the links for people that don't want to mess with governors, they are now off my watch. But the best thing this one does is that it allows you to set modes for different CPU governor tweaks on the fly. YOu will want to read this next: http://forum.xda-developers.com/showthread.php?t=1736168
On the truesmart we have 5 Governors available:
Performance - all on
Powersave - all (yes all) to lowest power
On demand - all scale frequency to power demand
Userspace - something odd that lets compatible apps set it ignore it
Hotplug - like on demand but can turn off one CPU completely
And from what I can tell we have 3 frequencies available on a 1Ghz chip (598, 806 and 1001).
You will almost always want to use hot plug unless you are benchmarking or manually switched one of the cores off as the others lack the ability to halt the second core automatically, so power is usually better, even than powersave. You also get to set the percentage of load that the frequency is upped and a powersave vs performance bias which I believe impacts how long the governor should be at that load before stepping up to the next level and how eager it is to step back.
I use uniform profile and set the following modes:
On screen or lock screen - hotplug - a small powersave bias and threshhold up at 50
Screen off on call or charging - powersave - max cpu 598, 2nd core disabled
People might find my charging profile odd, but I figure the device isn't overly usable in the cradle so why not have it charge as fast as possible, I tried performance but it got hot. With all this set, my phone idle battery usage now tracks up at about 2/3 the rate of my cell standby and there really is no loss in end user performance. The governor tweaking probably gets me and extra hour or 2 usage over the day.
After everything was done I have gone from 9 hours of charge with my usage profile to being able to last a full 18 hour day and still having room to spare. 36 hours off charge is not off the cards, so that is a four fold improvement. Have a play and let me know if it helps.
Here ya go. Remove the txt extension. This is the core of the edits that was getting a TS 10-12 days of 2G standby with no syncs and over 4 days 3G/HSPA+ standby with G+/Hangouts/Email and other apps syncing as they like.
Pay close attention to the loki99 edits. The governor changes alone save a bit of battery. It forces lowest clock rate and one core unless the device really needs both cores and higher clocks.

Ah you are still around. I have a 1/8/2100 (hence why I hadn't applied your ROM to benefit from those tweaks) is there anything I need to change other than the maximum frequency of 1001000 for that model?
There are no 2g networks in Korea or I'd have 3g disabled. So 3 to 4 days it is I think right now mine is tracking down at about 1% an hour, cell standby being the biggest consumer, is there anything that can be done to reduce that further?
Thank you I'll have a play. I take it I just put the script into the init.d folder and copy the parts of the buildprop to the system directory. Is there anything else to it?
Not really. I quit deving but somebody messaged me about this and pointed to this thread. 3G only kind of bites as the 2G radios are still on and looking for networks and using battery. Try DS Battery Saver and set it to "Agressive" or "Slumberer".
Aggressive will disable WiFi, data and syncs when the screen is off and every 2 hours it will turn on data/sync for about a minute and let your apps sync.
Slumberer will completely disable WiFi, data and syncs when the screen is off and only allow data/sync when the TS is awake.
Having wifi on at all unless there is a network it can connect to is useless.
My primarily use is for sports though, the GPS eats battery (as expected). But I want max power when starting.
Less crappy firmware with Bluetooth 4 and/or another dataplan may change my use though.
For more granular control, DS Battery Saver and Kernel Tuner have Locale plugin interfaces, so they can be used in Llama/Tasker. Tasker has some governor/CPU freq support too. Additionally Locale Execute plugin can be used to activate scripts similar to what Loki posted.
CPU Tuner works reasonably well out of the box, but I want to combine profiles with location, for instance wifi only at home. In addition, I have a data plan that require activation, so data/sync is only occasionally on. (Ad based, data, SMS, talk is free, but you have to watch ads every 2nd hour for data.) So for data to be on, the condition should be to ping some internet server. At home I use wifi when screen is on.
I have some Llama events setup now for multiple locations, may have to switch to Tasker to get what I want.

There are quite a few threads on this already including what I wrote (pasted below).
<<<<
I had two types of standby battery drain - mobile data and wifi. I have fixed both of them through lots of trial and error. From my testing and looking on XDA at similar experiences of people on other phones, these are bugs in Android rather than anything Elephone can fix through updates (I'm on the latest 20160419 update).
I fixed the mobile data problem by creating Tasker profiles to keep the phone on 2G whilst it's connected to wifi. I can't post links yet but a search on XDA/Google will find you these profiles. Maintaining a 4G connection is unnecessary whilst on wifi, besides, some people have problems receiving calls on this phone whilst on 4G. If the phone is not connected to wifi (rare in London because it's everywhere even on public transport) 4G comes on. Best of both worlds.
The wifi drain solution sounds counterintuitive but it is simply to set it to 'always on'. With both of these measures, my standby drain has been 1% overnight for the last two nights and roughly 0.25%/hour during the day. Standby drain on 4G whilst moving around London with location on at least quadruples battery drain to around 1-2%/hour.
Some of my other settings will have an impact too. I find the auto-brightness calibration of the P9000 poor, so adjust brightness manually (which also saves battery life). NFC, bluetooth, etc. I only turn on when needed. I use Greenify and have all apps Greenified except Tasker, Textra, and Hangouts. I haven't Greenified any system apps except Google Maps. Location is always on but mostly device only (again counterintuitive, you'd expect it to be 'battery saving') unless I am moving around in which case I have a Tasker profile to automatically switch it to 'high accuracy'.
I tried to get Xposed working so that I could use Amplify too (see my other post) but that didn't work. Since I'm very happy with battery life now that's not that important anymore though it would be nice for the further tweaks it makes possible.
There are too many other variables to list and everybody's phone is set up differently. However, hopefully using some of the main big gains I've listed above you can fix your wifi drain specifically and improve standby drain generally.
Well, it's somewhat problably what keeps the phone awake, this occurs after factory reset, i already did the Tricks you've listed and on screen Features and so on are all off, there are no Apps who should keep the phone awake Cause it's happening Straight after factory reset so there are no other Apps..

Finger print sensor or DT2W for sure. Disable them
