Hello,
i have a X8 and a X10i. Both of them use jerpelea's gingerbread 2.3.3 rom. i found something strange. the x8 is currently not used, so it has no sim card and is running in airplane mode, without gsm, wifi, bluetooth, gps.
i forgot to charge the x8 for 9 days, i expected the phone to be dead. but to my surprise it has not drained the battery completely, no, there are 72% capacity left.... after 8 days and 9 hours on battery!
i tried the same with the x10, sim inserted, airplane mode on, no wifi, bt or gps enabled. but the x10 looses 1-2% per hour, so the battery would be empty in less than 4 days. i expect the x8 to last around a month.
i am just wondering, why the x10 needs a lot more power when doing NOTHING than the x8 which has a smaller battery, too. power usage reports android system and phone inactive with 49% each. simply calculated, the x10 consumes roughly 7-10x more power than the x8...
test conditions: fresh installed J's 2.3.3 ROMs (x8: v003, x10: v008) - only difference: sim inserted @x10 (both devices in airplane mode).
try do the test under the same conditions. no SIM.
that`s the only way to prove any theory and compare build.prop as-well.
its not the same
you said you forget your x8 for 9 days
so you havent open the screen
the screen will use battery a lot
so if you open your x10 per hour
the screen will influence the test
I owned an x8 before i got my x10 and yes the x8 has a better battery life in standby mode, of this i have no doubt, i believe the standby processor in the x8 goes down to 128mhz compared to the x10 245mhz although i no longer can confirm this as i sold my x8
Display Screen is the main effect the battery... X10 screen are 4" inch display which drain battery very fast....
I think the processor also is the main effect of the battery...
Correct me if I am wrong...
Sorry for bad english grammer...
Easy mate :
X10's screen is 4inch , the X8 is 3inch ,also X10 is 480x854 ,X8 is 320x480(x3 consumption)
X10's CPU is 1ghz,X8's 600mhz (x2 consumption)
X10's RAM is 280mb , X8's is 128mb (x2.3 consumption,and yes memory also needs electricity)
So far only those 3 reasons give you a reason why there is a 7x more power consumption.
The rest? Dont know,guess optimisation or some other reasons.
But basically ,you cant have Extreme Power and Extreme battery-life at the same time,and the X10 vs X8 tell you that.
So yep,its normal.
Respect
That's obviously incorrect.
Screen off - no consumption difference
CPU - both run at 245MHz which is the minimal frequency in SE's frequency table
RAM - while that is true, your figures are incorrect. X10 - 384MB RAM. X8 - 192MB
Also, the battery usage is not directly proportional to the amount/frequency of components.
Try both on 2.1 stock ROM, otherwise it is an unfair test as jerpelea might have different hardware optimizations for both devices.
you must have some cpu consuming process running on your x10, my x10 actually have 67 percent of battery after 2 days, many phone calls, mails and sms.
on the screenshot is situation after first day of normal usage, some phonecalls and sms. it's my only phone so i can't do this 'total standby' test.

1)Okie i agree on the Screen-off no consumption difference,but take in fact that the phone STILL has to process the stuff in their resolution for when you turn on the screen,thus the 480x854 still affect it,which leads to :
2)Eventhough both run at 245mhz minimal frequency(which is not,as X8 runs at 125MHz when at minimal),they almost never achieve that as eventhought the screen is shut off the phone is still working in the background,or do you have to turn on the phone entirely each time you unlock it?So it still consumes x2 more power.
3)Yes the X10 has 384 and X8 192 of total RAM but im counting on USEFULL Ram,its like haveing a computer with 8gb but got a 32bit system which uses only 3.25Gb of ram,what do i care it has 8gb if i only use 3.25?
So there ya go.
Respect
Something is eating your battery on X10.
Here's my example... I've used my X10 without SIM and without wifi and BT for two weeks untill i got it unlocked, and the battery have lasted about 8-9 days, with some playing with cam and listening some music. Now with normal use SIM, data connections, wifi and all the rest battery last about 2 days.
This is such an interesting debate...................
No actually it isn't. Who cares?

1. OP said he just left the devices , proving point 1 yet again incorrect.
2. Maybe it is, yet 245Mhz will not use twice as much power as your so stated 125MHz
3. all 384mb and 192mb ram is usuable on the two devices. Maybe not to the user, but still usuable by the phone (radio).

Hehe we sure dont understand each other,but makes it more fun XD
1)Mate eventhought the screen is off the app's still are processed at X10's resolution ,thus the more resolution the more power consumption it has.Take in fact its like turning off the screen on your computer...Yes the screen doesnt take battery(electricity) but the GPU still has process the stuff in the resolution you had on your screen(for exemple 1920x1080),so maybe its not x3 as i said but it sure is 2x as the resolution is almost double.
2)245 will use 2x more power 125mhz (afaik,125x2 = 250 so ) but thats not the fact mate,if the screen is off and a app really needs process power it will use all 995MHz instead of only 600MHz so that is a power consumption
3)Alright then,be it 384 and 192,it still is double so 2x power consumption ^^
(Its actually the same takeing 280/128 and 384/192,ratio is still x2 )
Respect
But when the screen is off it won't be processing anything to present to the screen....

As far as I know nueDynamic Clock only works for the older chipsets. As Snapdragon has a different architecture it might not work. But not entirely sure.
Something similar ...
It is not working , of course .
I tried myself , and it can`t be instaled.
But some similar soft , or registry tweak ?
Chalenge for chefs !
Every new Rom release is focusing on Speed and stability , but not a SINGLE one on batery life !!!
Why is that ? Is not Important to you to have an extended period of uptime for your device ?
Here is a chalenge for you Chefs !
Develop a stable Rom with low consumption and great batery life !
Thanks !

The battery life on this phone is pitiful. The phone is professional liability without a spare battery or charger on you. Which totally defeats the purpose of making it slim.
If you cant travel without an extra batter or usb cable then HTC should have just put a bigger bulker battery in.
What happened to practical design. The phone has to function above all else. If you want snapdragon processing (which we all do) you must have a large capacity battery.
Nobody who owns and HD2 can expect to get through a full day of using the phone without the need for juice. I run out of power every single day and I am constantly enabling the in flight wireless shut off to save power.
Which of course means I risk missing phone calls.
Beyond that (and the audio lag) its a great device. Its just not ready for everyone yet. It operates like a prototype for a great phone for me.

I get 3 days out of mine from a single charge. I don't have any push services or overly regular updates. Apart from 1 email account that checks every 15 minutes, I set the others to every hour, set the weather update to every hour and set MyPhone to only run once a week. I was always a little cynical about people saying they could get longer than a day out of it, but then I actually tried it and it works.
Anyway, back to the OP. From what I've read on here, you don't need to "under-clock" the CPU as the chip only runs at its required speed - that's part of the Snapdragon design. Like I said - I'm just repeating what I've read on here.
...but it's already under-clocked during normal usage.

You didn't read his post and follow his link to that exact program, did you?
1) How to have best battery life? I currently already
-Turned off Bluetooth and GPS
-Wifi only when I need it
-Using SetCPU with profiles from another thread
-Low brightness
Im guessing that all the apps autostarting uses alot of battery so I always stop them with Task Killer but they just restart. I tried using Auto Task Killer but it doesnt seem to work. Any help?
2) I use like 40% a day so should I charge everyday or wait until its down at a certain level?
EDIT
Also, whats a good video converter to convert videos for the phone? Most that I tried takes forever and my computer is definately not a slow computer.
Stop using a task killer, the OS will handle the apps. If you keep shutting them down they have to keep restarting, that will suck power.
Any data sync will drain your battery if you us it to often, set it to a reasonable time frame.
I leave my screen on auto seems to work well, and you can charge whenever you feel like it no need to wait till it's low.
If you use Rockplayer you shouldn't even have to convert your movies unless they are full HD. It's a great player you should try it out.
Hi, mine goes down at an average of 1% battery per hour at normal use since the firmware update (v23).
I enable wifi only when I'm at home, for the rest I only use Edge/gprs because at my work the 3g signal appears to be too weak and 3G drains the battery really fast.
Bluetooth and gps are off, Google account syncing is on.
I believe that a lot of widgets have a negative effect on the battery life, so it might be a good idea to limit their number.

Ok I found out the major battery drainer via the battery usage in settings. It shows the the Display accounted for 80% of the battery usage. My display brightness is only set at aprx 25% and I have a total of 4 widgets on. Whats the problem?
Regarding the conversion, I am using rockplayer already but I just want to toggle the video settings a bit (mainly resolution) so the file size is smaller.
40% a day is a quite good result. what is your objective for a smartphone with 4-inch diaplay and 1G cpu?

More of a wish than an objective but a month would be nice
In the early 80s a 20MB HDD was about the size of 100 X10's and now my X10 has 32GB of storage the size of a postage stamp.
The computing power of an X10 would have filled a 10 story building in 1980.
Where are the big advancements in batteries?
What we need for the X10 is a Hydrogen Fuel Cell

Bottom line is that it's a huge screen and it sucks power.
Try this, turn off "everything" and play a 2 hour movie, doubt you'll get to the end of it.
Since the screen is so large battery life would have been better served by an AMOLED screen rather than TFT.
Gary.. Think this latest firm ware has a bug that shows the display draining battery much more than it really is.. You should ignore that. My display is set to auto. I get a full day from about 50%.

yes, the current battery technology is obviously far behind the development of mobil devices industry. egeryday, we see the faster cpu, better display and os etc. the battery has become a major weakness slowing down the related industries.

I really like specs of DHD it seems to be really great phone. Even if it lacks AMOLED display I still think that it would be phone arround. 4,3" display should be big enough to do light work on it which would include lots of browsing, emailing etc. I just wonder what do you expect from 1230 battery? I am still sticking to my very old but precious HTC Touch Diamond which is painfully slow and battery last only like 12 hours while I am using. So with all "improvments" (better cpu tech, older display and Android 2.2) battery life should be at least as good as EVO ? Thanks a lot for your opionions
PS I know that nobody will be sure until we get hands on DHD but at least we have something to chat about until we get final release date
The same DHD ROM on HD2 with base WM ROM optimizations gets me 1.5 day worth and its not running Android directly from the phone yet.
So I would guess it will be 1-2 days with medium-heavy use
x
Cool that would work for me Just wonder why EVO battery life is short? 4G drains more energy than 3G?
Not sure of 4G but rest is like this -
GSM : More Talk/Use time & Lower Standby Time
3G/HSDPA : Lesser Talk/Use time & Higher Standby Time
Hey guys, what do you think the battery life would be without 3g on? I dont have a data plan, and dont plan to get one (yet?), so i'll be using wifi for data. So with 3g off, and data roaming off, and even wifi off, what would u expect the battery life to be with moderate-heavy usage?

I think HTC lowering the size of the battery is a big indicator that the battery will definitely last you 1 day of heavy usage... I think if they was worried about the battery life they would have stayed with the 1400..

They are using unibody design for DHD that could be also reason since EVO has classic design with removable back than I would think that physically bigger battery fits to it.
Appart from SE X10 I have never seen a smartphone of DHD, SGS, Desire etc. caliber to last more than 2 days max. Even the SGS (wich has 1500mAh) doesn`t last more than 3 days (that was the max I could get from it) although the battery is not the one that GsmArena guys used for testing, does who know about the controvers around the SGS battery know what I`m talking about. So, I don`t think it will do better than 2 days (max).
I wish at least as a marketing tactic, they should keep same size battery (1400 mAh) as Desire. It's really annoying to know you actually downsize in terms of battery while you are making a device upgrade.

From my understanding the DHD consumes less than the Desire, so even a downgrade in battery total capacity does not mean you will have less autonomy.
I hope htc gets this right, i am really worried about battery life with heavy use.. It will be more power efficient compared to the evo 4g because the 4g uses a 65nm batt + likely the screen consumes more + the 4g is a battery eater.. but still i think the battery could have been a little bit bigger say 1320mah or even 1400mah, I hope mugen power or seidio come with a battery @ around 1600mah they can make that, the legend(Unibody) can have a 1800mah battery instead of the 1300mah that gives around 30 to 40% longer battery usage time in practice!
We don't know how efficient the new chip is yet. We will have to wait for reviews. But like all modern smartphones, expect it to charge it everyday. (if you are a heavy user)

Maybe HTC is right about less consuming maybe not, we will see but at least there are many people who directly look up the battery capacity and it a downsized capacity may them prejudge and not to decide buy. I know this is not such a big probability but If I were CEo of HTC, I would definetely go with same size battery with Desire but declaration with "less consuming" compared to Desire.

i think they were forced into using that size, otherwise they would have to make the DHD fatter to fit in a bigger battery.
dont think so,
Keep in mind that the DHD has a completely new processor in it with a new GPU aswell!
tests have shown that the DHD is 2x faster then a Nexus one with android 2.2! This new processor probably uses alot less power, and thus a smaller battery would be enough for atleast 1 day.
DHD sports a bigger screen than desire. when screen is on, I 'd bet DHD would drain more, whilst it could be less energy-consuming when screen is off.
To end this pointless thread in a whip:
1: 45nm VS 65nm - you can make the maths. This alone will yield a hefty decrease in power usage.
2 (a): the (only) potential power usage increase might come from the 4.3" screen, although that remains to be seen. WIFI/BT are standard.
2 (b): in order to decrease 2 (a), disable auto brightness and set a static, lower level.
3: Another contender for battery usage might be HTC's framework+apps+services. Once you get rid of the unnecessary, you'll save quite a bit of power. Once you get recovery and use an AOSP build (I HATE SenseUI), this will further decrease power usage.
4: In order to further tune the power scaling, use an UV/OC kernel + proper scheduler ammendments (once HTC posts the source on the dev site). You can tweak the latter with in the meantime with temp. root and a user script targetting /sys values.
I guess that should cover the basics.

hey man..there are rumors spred about new chips on board from sandisk with lock on nand. there's a chance that hd2 will be as u unbox, for a long time. just hope it could be possible to undervolt the same kernel provided from htc.
Or maybe not, everything has a weakness, even the lock on nand we will just have to wait...
Only had the phone for two days so this should improve even more:
overclocking to 1.4ghz, under clocking when screen off to 0.3. 9 hours screen off, didn't lose a percent, still 100 on desire Z. EPIC!

how many hours can you get out of it when you are using it throughout the day, e.g. email, internet browsing, twitter, bit of music and phone calls? using data and wifi?. Im on my 5th day and averaging about 14 hours, hoping that the battery hasnt settled yet, otherwise my hope is for the NAND being hacked and roms for optimal performance!
Do you actually get more real-life performance out of the overclocking (snappier menus, faster app launching), or the only place where it shows is the benchmark? Is Sense faster, or is the difference not visible (0.8 vs 1.4)?
On the other hand, underclocking could be really useful to preserve battery. But doesn't the processor underclock on its own when in standby (by design), do we need to use 3rd party apps?

contrary to what you should expect,
overclocking this SoC just hightens the clock's max roof from 800MHz to 1GHz, 1.2 or 1.4GHz, not the "permamnt" MHz count,
because it auto-fluctuates and adapt depending on usage
AND with the SetCPU app (which I assume JupiterDroid is using),
cycles per second can be optimized even more.
The phone won't go up all over the way to 1.4GHz when idle, but will maintain a very low cycles per second clocks, thus improving battery life
Here's my experience w/ battery life and overclocking the Desire Z (for today).
I only have it set to overclock to 1GHz and I have typical SetCPU profiles to underclock to 245MHz when not in use.
My phone has been off the charger since 9am (5.5 hours) and is sitting at 92% battery power. This includes permanent connection to WiFi (no sleep policy), receiving updates to email/gmail and some text conversations with Trillian and a 15 minute email (composed w/ keyboard).
Compared to my old HTC Hero (Running VR 1.5.0), this is a huge improvement, though with VR 1.5.0 I could run JuiceDefender & have similar battery life with the right profile setup.
Yup I even notice better battery life in actual use. My friends were running youtube and doing web searches like crazy on my phone last night + games for a good 5 straight hours and the battery was holding up well.
I've got to say, the battery life on the Desire Z is outstanding... 18 hours with light use and battery still @ 92%!!!
What about 1GHz core compile?

are you using set CPU and overclock?
Is anybody getting time without a signal percentage in the cell standby item in the battery usage? Im getting 12% sometimes more and im getting about 14 hours battery life with moderate use! I dont feel im getting the best out of the battery and worried this might be part of the issue!
Hi guys.. sorry for the novice post.. i have had my Desire Z for a day and am interested in overclocking it - but
a) are you saying it possibly INCREASES battery life?
b) is the speed diff noticeable in day to day use - or just benchmarks?
c) How do i overclock - what is SetCPU and how does it work?
I don't think my battery has settled yet .. I hope not anyway, and I just (temp) rooted and overclocked to 1Ghz last night, haven't tried higher yet because I feel like my battery is kind of just disappearing so far, none of this epic "all day and then some" stuff some people are reporting. I think it may be that fact that I've been using the device pretty sporadically so far, and it hasn't had a chance to settle.
Also "cell standby" seems to be using a lot of battery, and I'm thinking that's because I'm unfortunately in a spot where I get extremely poor to no coverage most of the day. So I'm thinking the cell radio is using a lot of juice trying to get that 1 bar I sometimes see here. There didn't seem to be a way to easily disable the cell radio without disabling wifi though, until I found this "airplane mode wifi tool" on the market which I just installed.
So now my cell radio GPS and bluetooth are all off while wifi is on, hopefully that will make a difference. I'm wondering if using 802.11n is more draining than 802.11g also I know both my router and the desire z support N but "network info II" reports I'm only connecting at 65Mbps, while my laptop connects at 150Mbps.

Hi guys.. sorry for the novice post.. i have had my Desire Z for a day and am interested in overclocking it - but
a) are you saying it possibly INCREASES battery life?
b) is the speed diff noticeable in day to day use - or just benchmarks?
c) How do i overclock - what is SetCPU and how does it work?

I don't think there's any way overclocking can actually increase battery life, but managing CPU speed with SetCPU seems to be more effective than the default behaviour for some reason, so the fact you're overclocking when using it but underclocking when not using it results in longer battery life. I'm pretty sure it does regulate the speed automatically without setCPU but maybe it doesn't clock the CPU down to absolute minimum by default when the screen is off?
Anyway the noob friendly guide to overclocking by JD is on the forum with an [INSTRUCTIONS] tag.. I can't link to it apparently since I'm a noob.
Edit: Added link ~TheRomMistress
Thanks guys. Main thing i'm curious about is whether i just install SetCPU or i have to "root"
Yes, SetCPU needs root access.
Still trying to figure out how the OP is underclocking to .3 using SetCPU.. Lowest I can go is 245..
Unless I'm an idiot and completely missing something.. I'd love to turn this phone way down when the screen right off. As it sits, I'm lucky to get a full day from a fully charged battery.

Your mileage may vary
You can check by yourself and then uninstall if you are not satisfied (or just reboot and changes will dissappear, since we don't have permanent root yet)

Hello guys,
I have been researching, experimenting and trying many many things to understand how cell phone battery consumption works and how to find the solution to be able to use the most of the battery! HTC did a very bad job on the battery side of M9 and in my opinion, Battery is the only downside of M9. I will explain later why I say that.
I will share the tips and tricks I found to get such battery life that none of you ever think of getting out of M9. Look at below battery stat. It looks like M8 battery stat which made all M8 user really happy with their device! Now we will be enjoying that too! BTW This is my birthday today, so its a very good day for me to post this thread. Wish me luck!
First Let me explain some things about why a phone drain the battery in relation with CPU and Apps.
1. Random CPU freq change.
2. CPU heat.
3. When phone is idle, means you are not doing anything(not opening apps or neither you have apps opened in background, CPU freq not being able to stay down.
4. GPU related drains(while playing games or not)
5. Display category. Amoled or LCD or what type.
6. Buggy ROM keeping wake locks. ( I am not going to talk about wake locks at all. There are good enough threads for this)
7. Apps. Each you open and close an app, the cpu starts working, freq goes high. So, this means, the less opening and closing you can do the less battery you consume. Now, all these concepts of app killer running in background, killing apps after a certain interval, ARE COMPLETELY WASTE OF BATTERY AND NOTHING ELSE! Android keeps opening apps in background according to its algorithm. So, if you want those app to stop bugging you in the background, then task killers are NOT ANY USE AT ALL! Remember! The less app in background the less drain you will get. We usually use home button a lot when coming to home screen but we dont realize the app just got minimized and consuming as much as battery as it would if it was open in the foreground. So result is, bad standby time + more drain while screen is on.
So how can you get rid of those background apps? Best way is to use Greenify. Greenify is the only app that can hibernate any app without hogging battery by itself and keeping wake locks. How to find which apps to put under auto hibernation list? You need 2/3 days to observe. Greenify will automatically mark those apps which opens in background. Once you are with good number of apps, greenify all of them. In greenify settings, select autohibernation so that even if some gets awake by the app, can be put to sleep again. Now two things will hapen because of this.
1. You will consume MUCH LESS CPU power means you will save battery. The device will be very snappy. Ram will be at least 1.3 gb free.
2. It will take more time for an app to open which are under your hibernation list. Now I have thought about it. My conclusion is that, I need to choose between battery and super fast device. When I on battery saving priority I follow the solutions of this threads and when I am not worried about the battery I try to enjoy the device.
So, we can restrict apps from hogging with greenify. Now how to control the CPU?
Out CPU is actually ULTRA FAST and is capable of fastest performance amongst all smart phone around. Here is the antutu benchmark to show how crazy this CPU can be! So crazy CPU will drain battery. Its cor-relational. So, the solution is to limit the CPU from putting too much power, especially when it gives more than the phone and user needs. When I was using HTC Sensation, I was feeling like, there are 2/3 things which should be better and I demand nothing more from a phone. LIke battery, camera, ram etc. But after M7 I have never felt that the phone should get faster and we should get like 4 gb of ram either~! But newer means faster and better. So CPU + GPU are getting more powerful and eventually the phone is getting such overrated power which it doesnt even need! After all we are not flying to moon with our phones! lol!~ Right?
ok Now how to limit the CPU?
We need
1. Elemental x kernel 4.01 installed with all stock configuration. This is important. Yout must use STOCK values. I have seen anything else other than STOCK values drain the battery even more! So STOCK IS BEST!
2. Elemental x kernel app or Kernel adiutor kernel config app to tune the kernel for our battery saving mode.
Steps-
- Set HTC pnp manager off
- Set max cpu freq of small cluster to 864 mhz, min cpu freq to 384
-Make sure you are on stock gov.
- Set GPU max to 320 GHZ.

Disclaimer: These settings will make the phone performance slower but not laggy. So, just consider a power saver package which has very decent speed too!
After applying these settings, you better restart your device to let settle it with new rules for CPU. leave the phone for 2/3 mins. The things that you will notice when you turn on the display -
1. No rapid CPU freq changes
2. Phone is ultra cool as the temp of CPU and battery has gone down to 35 C. M9 with default setting will never come down to 35 c ever! The lower temp would be 40 c. So, cooling the cpu will minimize mA consumption.
3. when you open any heavy app like fb or chrome you will see the consumption mA rate is almost half of what it is with default settings. Max rate of discharge was 700 mA for me with 50% brightness + 3g internet + FB/chrome/youtube.
4. When you leave your phone to sleep, here is the fun! I have never seen such low mA discharge rate on M9 and I didnt even expect! It goes as low as 40 mA! Insane! The avg screen of discharge rate I found was 70 mA which means on full charge our M9 will get 40 hours standby! And that is with internet on.
5. If you are charging with official m9 charger, you will see the charging rate is 850/+- mA while your display is on with internet. When screen off it will reach mac to 1340 mA. My phone previously was charging at 600 mA with screen off. So, now 0 to full charge is only in 2 hours.
6. Clash of Clans used to drain 1200 mA and now it drains only 550-600 mA.

Hope this helps. Please post your battery results. And dont forget to tell me if you like this post. This will inspire me to make more posts.
Thanks!
I'm in the search of the perfect battery life too haha ????. Please continue posting about battery improvements. Thanks!
My battery life goes way up when I put the phone in the glove box of the work truck. 0% drain over 5 hours, checked it for call a few times and that was it. I leave data and stuff switched off until I'm going to use it.

Instead of turning PNPMGR off, have a look at this first. http://forum.xda-developers.com/one-m9/development/mod-htc-one-m9-enhanced-thermal-t3369574
It's a pretty indepth thread on the pros and cons of PNPMGR, and also custom thermal configuration files that change clock speeds of your CPU, dependent on your usage.
Also, your Antutu benchmark picture isn't anywhere to be found.
What about CPU boost? Do you disable it?

I do all like u but my m9 is still after few minutes too hot.
I never was more diaappointed with any another of my phone and heating and poor batt life like on m9...
After one hour of browsing internet I'm over 50% down.. on stock mm. That's shame for HTC. Now I'm back on my 2yrs old s5 with still perfect battery life..
I don't get any overheating on my m9 at all. It's on stock marshmallow still. Bought it used a couple weeks ago.

Hi,
If you did an OTA update to MM and are losing that much battery in just an hour of heavy use, then I would back up everything and do a factory reset. I can go for 5 hours of very heavy power user performance before dropping to that level. Either that, or you have a malware app on the phone that is being used in the background. Which a factory reset will also solve.( except in rare cases, requiring a firmware reflash)
