Hi Guys,
I was wondering why Android on HD2 eat up so much battery. Earlier I was thinking, that android is running of SD card...so its the case. However this is not true as in Android HD2 NAND thread its been mentioned many times...that battery won't increase significantly even after NAND install of Android, so where lies the problem...is it because power management drivers on hd2 android not good enough...just curious?
Regards
There must be a problem with your android build or you are not properly managing your battery life. To enjoy good battery life you need to disable radios via power control, and keep screen brightness low.
Current widget tells me that in standby my hd2 uses 3-7 mA. This draw is fine when compared to similar android devices.
Please provide some details on your build and your reading from current widget.
I think he was asking about how much the HD2 life in android is shorter when compared to WM6.X
If this is the case, this has much to do IMHO about how Android works in its innards.
The Android OS has a way of controlling the apps installed in it, to know which apps do which kind of stuff. Like, when a new app is installed it has a file that tells the OS all features it does, and which of those features can be called by other programs (an example is the gallery 3d, that can be used to open pictures of certain types, every time a file that it can open is accessed android asks [if you have more than one type of gallery] which app you want to use to open the picture).
With this kind of control being done by the system in real time in a way totally different from windows (register??) the OS probably need more awake time and probably use more battery.
With the same amount of time spent using similar stuff in windows mobile and android, WM really rulez in terms of Battery Life. BUT I really prefer the new life Android is giving me in HD2. I'm really happy again, feeling like I have a brand new toy again.
P.S: I'm oversimplifying the way this works, without even mentioning the services, widget services, and several other stuff that are running in the background all the time.
i get about the same battery life in winmo n androud. make sure u have a good radio n compatible rom.

People always say those things...
Well, let me just say that I'm using one of the best combos out there, and yes I have tested almost all combos you can imagine by my self in my own phone, so I wouldn't rely on someone else's idea of a perfect combo.
Tested more than 10 roms (the list is long so, I wont bother saying all of them, but the most used ones are there, Chucky, Miri's, VBNrom, Dutty's, and several others.
About radio... 2.10, 2.11, 2.12 and now 2.14 I have used all of them too and combined them with each rom...
Right now the best combo FOR MY PHONE and in my opinion is VBN 3.14 and radio 2.14
Multi boot, autoboot android 6sec.
I really think that what is most important is the build, with the same builds, almost all WM roms made for android, and Miri, have the same effect for me, the radios I must say that 2.12 and 2.14 are the best, and 2.14 has better reception in my country, for me.
So, as I have said, FOR ME, the best combo is resumed to VBN 3.14, radio 2.14 and any android build, right now using Desire HD 3.1 from Mdeejay with several different kernells (still testing them)
The kernels and the build are the MOST important thing after you find a good combo.
With the best build/combo and a good WM rom, doing similar things (surfing the net for the same amount of time, phone in sleep mode for the same amount of time,same time talking and etc. the best battery life is surely for WM 6.X hands down.
BUT if you are really getting the same Bat life, you are a lucky guy keep the settings you have, because I must say that I have constantly near me 5 HD2 (from friends), all of them with android now, and every single guy says that the bat life is nowhere near WM 6.x
I could go a full day in WM6.5.3 and have 50-40% remaining in the end of a day with heavy usage. Android, with moderate to heavy use, I'm happy if I can reach the end of the day, and even happier with some bat left
Greetings, Santroph.
I agree battery life is not comparable to WM6.x. People who claim they get the same battery life most likely have a buggered up WM6.x setup or they don't know how to manage power/settings.
Which App are you using to monitor power consumption?
Currently I use PowerTutor.
One time I wondered how 30% of power were lost over night?!
So battery lasts maximum one day until it's empty.
On WM 6.5 it lasts for about 2 days, like santroph already said, too.
A friend of me told me, his HTC Desire has about 80% in the evening. Do they have a better battery?
In usage I have about 540-600mW
He has got 550-650mW
So seems the same power consumption.
Regards

HD2
I actually get around the same amount of battery life as well. Just running the stock Froyostone 2.1 without tweaks (don't even know how to do tweaks if my life depended on it). Current Widget shows 0mA when waken up from screen off and hovers at 3-4mA with screen on and idle. Battery drop 1-2% per hour over night.

I have TMO US HD2 and I'm using NRGZ 21916 18Sep ROM with 2.14 radio. For android I'm using pongster's HyperDroidSense V1.1. I'm using only 2 widgets HTC Analog clock and Weather channel. I have set the screen brightness on automatic and to tell u its quite dull, not at all bright. I've also disabled all Background sync's and no WiFi or bluetooth is enabled...
I do like to fiddle with my phone every now and then...but its not heavy use, I would say its moderate.
Battery life i'm getting is by the end of day, the battery is drained and have to recharge.
Before this android ROM i tried warrenb213 CM6 9/6V1.5a which is claimed by some user's to give best battery life on TMO HD2. Its stock android rom with CyanogenMod...battery life was little better, but it was slow and it didn't had instant wakeup...it took 2-3 seconds after pressing the button to wake...and personally I prefer HTC Sense UI to stock...
On WinMo my phone easily last 2 days with some battery % (about 20-30) left and can easily give me third day too with light use on 3rd day. And by no means i'm using a minimalist WinMo setup...I have CHT v1.8.5 and the same analog clock with seconds hand enabled.
So battery life on Android << that on Winmo. About the argument that Android uses more battery due to how its build. I don't think its the reason, because HTC's other phone like Desire or Desire HD have the same 1230mAh battery and have similar specs...but there battery life is similar what HD2 gives on WinMo.
Also, you must bear in mind that comparing the HD2 to the desire with battery life, the desire is obviously going to win. The desire has been made by HTC to run Android, unlike the HD2. The desire does have a slightly larger battery (i think) but the desire has been optimized by HTC so that it uses the least amount of battery possible I.e when in standby etc.
I don't know all the specifics but this is what I've found out
Hope this helps

^^ya, i do understand...but to me its happening like battery life on hd2 w/ android is like 15 hours from 7am in morning to 10pm in night....WinMo give easily gives like 50-60hours depending on use...desire has similar as i've heard...
Agreed not optimized, but I expect it to give 40hours with full charge?
It is not optimized I guess? I get 6-7 hrs on winmo but 5-6 on android.
We can't compare with Desire, even if the hardware are really similar when looking at CPU/GPU, RAM, radio and stuff like that, we have e HUGE NORMAL LCD screen, that really takes way much more battery than Desire's Smaller Amoled screen.
Recent tests have shown that the new desire with Super LCD (thats way better than ours) do waste more energy than the AMOLED one (despite what HTC has to say about it).
I think that we should compare it with our own phones with WM, and probably with the new Desire HD or Evo 4, which have the same Case/Screen and very similar hardware too (despite Evo beeing CDMA).
IMHO...
P.S: People say that the SD card doesn't have anything to do with the battery drain, and that nand should be the same. Well I can say that this IS and IS NOT true... It all depends on which card are you using. I have 4 MicroSD cards, and they all have different behavior with the same combo/build/kernel/battery, even when in sleep mode with everything else (connections and all) disabled.
I have used WatchDog to see if any program was strangely making this happen, and I didn't find anything at all different when the Hungry SDcard was using that much battery, it was all it's fault.
2GB class 4 -> 5-7ma stable
16gb class 2 -> 3-7ma stable
8gb class 2 -> 5-9ma stable
8gb class 6 -> 5-80ma not stable (can be ina 5-7ma for hours and suddenly be in more than one hour in 40-80ma)
I prefer to use the 16gb class 2 for more battery, since the performance is not that better with the class 6 in android.
I've tested this a lot, and retested.
Greetings, Santroph.
I think that the HD2 battery is shortened by the display (Samsung Vibrant is awesomer in that respect) as well as the processor. If I throttle the processor down to 384mhz and keep the screen at 33% (automatic backlit) then I can get pretty decent battery life from 15-24 hours?
Hey all,
Quick question - for some reason I have really dodgy battery life in any of the most recent Android builds. This includes the Sense HD and the SuperRAM builds, with both recent MDJ & Hastarain Kernels.
If I leave the device in my pocket for a couple of hours, in standby, the "Battery Use" claims the Display is the primary cause for my battery use.
Just looking at it now, Android System and Android OS are both on 12% and the display is at 57%. That's after the display being mostly off......
I've tried three ROMS, including VBN's Android build, an official 1.66 HTC build and an official 3.14 HTC build. Furthermore, I've tried the 2.15.50.14 and 2.10.50.28_2 Radio's, both recommended for good battery life.
Any ideas?
Thanks
Jon
I am wondering the same thing. I am running darkstone hd2 froyo v3 with hastarins 8.5.1 oldcam kernel, everything runs great but it says display is killing my battery. If there is anything I can do about this I would really like to know.

Phew, it's not just me then! If I could be bothered I'd dig up an old sense build with and old kernel and see what happened. However I can't remember which one worked best as I change my ROM on what feels like a daily basis!
I have been using this as my daily build but I really wish there was something I could do about the battery drain. If it is something about the phone that I can't change or if a different kernel or something would help, I wish I knew. Any help would be appreciated.

it's not just you indeed, it's everyone there's at least two threads already about this.
Well, I dont really think its killing my battery life, however i did notice that its lower than when running winmo, I checked the settings and it says display is using 60% of power, I didnt really think anything of it as i guessed the display is easily the thing that requires the most power. So perhaps I have this problem too? I dont really know
Winmo I would get a day, perhaps a day and a half if i was lucky, android i get a day.

That's the thing you see, if the display is off for 2 hours, on for say 3-4 mins while I check my e-mail, it's still at a really high figure. Yes the display causes battery drain, but no where near that much.
I wonder if it's purely a kernel thing??
I only get 5% on my display battery drain.

I've noticed it depends what Android rom your using. The issue for me is either the Android System OS is using 60% & over or the display is using 60% and over. Either way the display or the system is the battery eater in my case lol.

What eating mine is cell standby and wifi, both 35-40% while android system is only 20% and display is 5%.
Sent from my HD2 Droid using XDA App
My display always takes up more than 60% of the power usage, but I have had builds where it's reported very low, I don't pay much attention to that anymore, they're probably not that accurate.
I did ran a quick test the other day of battery usage in winmo vs android. In standby both android and winmo were about 3-6ma. On the dimmest setting with no app running, winmo used 78ma, and android used 95ma, so it's a little higher, but not extreme.
I'm running at a crazy 67%...
For the heck of it, turned off all radio, left thephone @ 70%. Came back 1 hour later, tells me this percentage and the phone is at 63%...
Weather it's the Cell Standby, Display, Wifi or the Android OS, something is always taking power. If your phone drains completely in an hour or a day, the battery usage is just telling you what is drawing the most power percentage wise. 3mA or 300mA, it accounts for 100% of what's being used,screen off or not.
My android os only uses like 5% maximum, display is usually 60 though

What do you mean?
So I've flashed Juwe's Smart Edition v4.3.1 recently, and after some usage, I have found it worthy of a review. I must say that I really like it, and find it the best ROM I've used so far.
Here's the official thread in case you want to try it out: http://forum.xda-developers.com/showthread.php?t=964672
Juwe's is a JVH based, deodexed, CWM'ed, rooted/busyboxed(as usual) ROM with many more features. I found the following features highly advantageous:
Includes all Google Apps, which some custom ROMs lack
Includes Spare Parts+ and SGS Tools which have many cool features like script shortcuts, phone keypad secret codes, controlling window animation speeds etc.
As stock apps are deodexed, they can be safely removed and when they are removed, they can be backed up.
Includes Launcher Pro, which is CLEARLY the best and fastest launcher in my opinion.
Shows battery percentage on the notification bar, a feature which will please most users I presume
Comes with a black/white theme with some ugliness here and there, a good looking theme nonetheless.
A truly EPIC sleep animation, you'll understand when you see it
Very good looking window animations.
Includes an EXT4 filesystem converter which can convert /system /data /datadata and /cache to EXT4 and back to RFS.
Nearly all unlock screens available on any Android device can be chosen from.
INCREDIBLY low power consumption when sleeping (screen off, device on) compared to the stock JVH (it literally drinks the battery contents). Note that the HSPDA data connection is ON at all times.
Fairly low power consumption when talking on the phone (stock JVH consumes a lot of power on this task also).
Average power consumption when screen is on and the device is used. Note that window animations are fully enabled and Digital Rain live wallpaper is displayed on the background(which consumes a very large amount of power).
Average power consumption on WiFi, decent signal.
Amazing GPS. Absolutely fantastic connection speed, very low power consumption.
However, there are also some minor points that need repair or change:
Compass doesn't work.
Screen brightness seems to adjust itself randomly and poorly indoors, resulting in an abrupt brightness change every 10 seconds or so.
SGS Tools cannot find busybox?? Sorry for misreading, it says "If it says 'cannot find busybox' install it from the market".
The looks of the pop-up menus (accessed with the menu key) seem to lack that final touch.
OMG please replace that terrible bootanimation!
Note: The Android OS battery drain problem exists (as expected). This will only be fixed with an official firmware release.
Solution to the compass problem: Go to Settings -> Display -> Horizontal calibration -> Place device on a level suface and hit the button
There are also some other unfinished tests that needs doing:
Longterm WiFi quality/power consumption is not checked yet.
No "Gingerbread Android OS battery drain bug" encountered yet. Cannot be sure.
GPS is not tested yet, as it requires that I get off my lazy ass and go outside
Hope these observations clear the minds of people who consider trying Juwe's out.
Yes, Juwe has done a good job.
4.3.1 doesn't drain battery much. When I had other ROMs, the process 'Android OS' mostly needed 63% of the battery, with this ROM only 2 - 10.

Your problem being the one explained here http://forum.xda-developers.com/showthread.php?t=1039696, I must say that even without the drain issue, other/stock ROMs drain much power.
If you post the "defects" that you found (as well as this full review) in the original rom thread, I´m pretty sure that Juwe will be glad to help you.

However, I had this problem with lots of other ROMs (even with (Juwe's 4.3), but not with 4.3.1.
And I don't have any problems with busybox.
If you don't like the bootanimation, you can easily change it. Download one of the bootanimations here one XDA, copy it to your sd-card and copy the *.zip-file to system/media and rename it to bootanimation.zip.
GPS works great.
I know how to change the boot animation, I just think that this ROM deserves a slicker one.

Unfortunately, I too have experienced the battery drain issue today. I'm not too disappointed though, this is known to be a general JVH/JVO problem, and the fix must be done by Samsung/Google. Updating the main post.
Ok, I have found the solution to the compass problem. Updating the main post.
Thanks for th review mate. Wanted to try Juwe's ROM, will do it when I go home tonight.
Ok, I think I've misread the message given by the SGS tools, updating the main post.

Hi, I hope someone can help,
I flashed my Samsung Galaxy 3 I5800 with Kyrillos' ROM v6.0, NON-OC
Everything is working 100%, apart from one thing,
When I go to, Settings - About Phone - Battery Use
It is saying that my Display is using 86% of my battery???
Can someone help, I have the Display settings as follows,
Brightness = 10% / Auto-Rotate Screen ticked / No Animation /
Screen Timeout = 30 Secs, Power Saving mode Unticked.
My friends phone is only using 14% on the display.
Hi..
I'm sure this is a bug in all the froyo builds rolled out by samsung..
Even my phone displays about 90% on display all the time even though I keep the brightness to minimum..
But this thing is solved in the gingerbread builds.. I used CM7 Alpha 4 for over a month and the display battery use never got above 20%
Yup. Even mine shows a pretty high value.
clarkkov said:
This is not a bug, your display is actually using that much battery. Display is the biggest spender on this kind of devices.
Your friend is either:
1. not turning his display on that often
2. using the phones other peripheral hardware that much that the display is really at that percentage respectively to other hardware - this percentage of use is relative to absolute phone use
3. is lying to you

That data is hypothetical anyway, and even if it works at least remotely accurate, it does so only on real genuine Android devices. SG3 is not a genuine Android device, you can't expect anything to work correctly on this device, tweaks, mods, advanced features etc. The whole OS is full with non standard and improvised features, remedies and solutions to work on this joke of a device (I'm now talking about both 2.2 and CM7).

CM7 is very well constructed if compared to froyo..
Talking about standards, we have to live with what we have got (even though its crap) or shell out huge amounts on high end phones..
Although cm7 isn't totally bugfree it displays a fairly correct report about battery use whereas all froyo reports is display and android os
Well it starts by 100% (duhhh).and your display is the thing where you press on so thats the thing you use alot xD

Try to download from market a.k.a batery saver for acer iconia without any results (thor mod with i have is based on assus transformer and market shows incompatible version?)
Dear Pavel,
this is a rather old issue, solved long time ago. You can just add the following lines in your build.prop file, located in the system folder:
ro.carrier=wifi-only
Thor's ROM features this tweak by default so you don't have to do anything - no cell standby.
Well thor rom have this line indeed. And when U check settings about tablet battery indeed isnot showing .
When U install any other app to show battery stats actually shows cell standby and phone idle. I using norton utilities but few other ones shows.
I left for a night tablet screen off, gps off , wi fi on, airplanemode on and after 6h i have 15 % drop down. 8 H on my iconia possible when everithing is off.

Writing this post 3% down... and tablet was bought on black friday is brand new is that normal ?

If your tablet is new did you fully charge and then discharge the battery to about where it auto shuts off.

There are a couple of things to mention. If you are running an over clocked processor, this will of course use more battery power. Especially with thors roms, because the last time I looked, depending on version, it installed over clocked to 1.5ghz. If you don't need that much, try setting it to 1.2 for example.
Apps that are always running and synching. Things like weather apps, mail, fb, etc. And... those lovely battery apps (a waste of time). And this also includes Norton, as it runs as a process. All of these use battery power.
And as briandigital said, let the battery get a few full changes. Usually takes them about a week to settle down.
I agree with U. Those apps using battery. For example weather widget 0.5 % or norton 0.5 % but still shows 60 + % cell standby or 2% phone idle. wifi over night 30 % with checking mail every 15 min.
Over Clocking got nothing to do with this (1000 on screen on 400 on off) system proces phone is running all the time draining battery.
I have thor 14.2 mod and to get 100 % shure I flash again kernel and dubble chec for wifi-only line.
Wipe battery stats and 10 min after cell stanby 30 % after 30 back to 63 %
Or 5 diffrent apps from market are wrong showing cell standby and system process phone working and draining battery or this all solutins are not really working. If it not showing on /settings /battery is not mean process is not working
Anybody know how to kill that process and prevent to run ?
so can write small script to kill it"

I'll ask you a silly question.
And only because I didn't see it stated anywhere (or I missed it)
Are you running an A500? or an A501?
3g USB Dongle?
Did you run any "update patches" concerning 3g Dongle support?
Reason I ask, is that I did some of the testing for the kernel version you are using. (3.9r3). And frankly, I haven't heard a lot of 500 users complain about "cell standby" with the 14Rom. In fact the combo should be giving you extremely good battery life.
You said it only shows cell standby when using some other different application? I might suggest the app is not telling the truth.
Typically, losing 10% overnight with wifi on, is pretty normal. During testing, I lost 8% on internal 3g, and about 10 or 11 with Wifi. FB and Mail not's set to 1hr intervals. WX at 3hrs.
The fact you still have the menu system for mobile networks (2g/3g) is very puzzling......
Did you post this issue on Thor's site? www.tegraowners.com

You said it only shows cell standby when using some other different application? I might suggest the app is not telling the truth.
Typically, losing 10% overnight with wifi on, is pretty normal. During testing, I lost 8% on internal 3g, and about 10 or 11 with Wifi. FB and Mail not's set to 1hr intervals. WX at 3hrs.
The fact you still have the menu system for mobile networks (2g/3g) is very puzzling......
Did you post this issue on Thor's site? www.tegraowners.com

Ok from begin
1. A500 wifi only 16 Gb ver, staples for 299
2. No any addons clear tablet nothing plugin, kernel and rom from thor14v2
3. No any updadtes
4. Am not complaining about battery life, am complaining about stupid process what is draning my battery.
5. A can post 5 screenshoots of different apps whitch showing cell standby process draining battery. Whatever i will download from market kit is showing same so i believe they're not wrong.
6. Never post that to thor forum. Here is way more chances to get respond

You should re-think about posting on Thor's site. He's typically pretty responsive. Unless it's a stupid question, or somebody's not nice.
The cell standby issue is an old one. It's because the 500 and 501 share the same hardware with the exception of internal 3g for the 501. And because of that, the share mostly the same OS code.
Thors rom, was based on the asus transformer. I don't run it, as it doesnt fully support internal 3g.
It's possible, that the process is still running, only hidden from view based on the images you supplied with the modified build.prop set to wifi-only.
In this case, I would ask you again, to post the issue on Thors FORUM under the Rom ver 14 topic. It may take him a day to answer, as he's working on ICS right now.
In the meantime, here at xda in the a500 forum, there are several "older" topics covering cell standby on the a500. One of the fixes at the time, was to "freeze" the telephoney.apk (get some error messages) then reboot.
Just do a search for cell standby, and you'll find them. I found them earlier today through Google (but can't remember where), so you should be able to do the same.
Well I did some research before I bother U and other solutions is to rename / remove phone.apk witch may solid brick my acer. Am wonder if I rename it and hard reset can I be able go to recovery ? And restore prev backup or this is gonna be a perm brick

Well Pavil, those posts are a little old.
And, sometimes people call things a "brick" when they really don't know what a brick is
BEFORE I would rename any apps, I would try this, Install Titanium backup. Once installed, and root granted of course, Select the telephony apk, then do a "freeze" on it. Reboot and check things. You may want to freeze those other couple apk's if it doesn't fix it. You will probably get some error messages when you first freeze it, but ignore it, and reboot.
But BEFORE you go freezing things, do a recovery backup first This way, you can get back to where you were before freezing.
Then see how things go.
EDIT. Stop using battery apps designed for phones. They may run on Honeycomb, but if they were designed for devices that have a functioning radio, they know no better than to display an erronous stat.
But honestly, battery stats in android are somewhat misinterpreted.
Example. If your device used 10% power. And the stat says Display used 80%, It means that of that 10%, the display was responsible for 80% of it. Not 80% total battery power.
In the meantime, I see you didn't post on thors site? Ok, I'm on good terms with him, so I'll pose the question to him.
Thanks for interesting of my problem. I try today to ps ,get pid and kill but this buster is restarting by it self...
Well i will wait for re ftom Thor and ICS. We will see...

It appears from your screen shots that you don't have your wifi set to disconnect when your screen goes off. I could be mistaken, but if it's not, changing that will help battery life immensely

Yeah, no sense in messing things up. A pity I don't have an a500 or I'd test it myself.
You could try flashing one of the other roms, and see if the result is the same. For example Taboonay. I ran it for quite awhile with Thors 3.9r3 kernel. Or you can use the kernel it comes with.
Answer from Thor is that he's not aware of the cell.standby issue as nobody else has mentioned it, and all his stuff now is set up for ICS, so he doesn't have the time to check it out.
So, maybe you just have to live with it. Seems your battery life is ok, so I would just ignore it for now.
Did you wipe your battery stats from CWM before flashing?... And by the way thor's ROM has CPU clock set to 1.2 GHz by default.
p. s. Moscow Desire is right about apps made for phones.

Yeah, he had to back off the original cpu install recently due to a couple users couldn't flash at that speed (1.5). Not all CPU's are made equal.
(the real issue here, is the old "cell standby" issue that a500's had in the past)
But again, like drkalo affirms, you shouldn't be using battery apps that were designed for phones running android 2.3. I suspect (considering nobody else using Thors roms complain about cell standby), that the phone battery apps have this hard coded, and expect it to be there, so it displays a random percentage. Probably because it see's the phone apk's in the OS and naturally assumes it needs to display something.
Yes, the apps will mostly function on Honeycomb, but, are they really made for tablets? Probably not. (even if they say it does).

So what to use to check ral battery / process usage?
Sent from my EPAD using xda premium
Personally Pavil, I do not use one. Except what comes in the rom. There's really no need to get anything else. And frankly, I don't hear a lot about folks running 3rd party battery apps on their tablets. So I'm not going to be much help on suggesting one. I just know most of the task and battery apps, were designed for phones on android 2.3.
I gave up on things like battery apps, task killers, task monitors and the likes a long time ago. I learned to manage things on my own like most others do. There's no reason, once you learn a little about how android works, to add apps that take even more resources.
Bottom line, you can have every app in the world to monitor things, but what really matters, is what the "actual" battery life is.
For example, I can go 12hrs with normal usage, and still have 60%. This includes internet, sms, mail a few times, maybe some video for an hour. It depends.
Or, I can play angry birds 7 hrs straight before recharge. Not bad! And I run my processor at 1500ghz.
You can instal a cpu app, like cpumaster, and set profiles based on how much battery you have left. I typicaly set mine to start at 1500ghz, then do 2 extras to down the speed based on battery. When I use them, I can run for almost 3 days with normal usage. I do this when I know I will be camping with no electricity.
I have 4 of these profiles on my phone, and the longest I lasted, was almost 4 days before recharge.
Wish I could help you more.
