Battery Inconsistency - HD2 Android Q&A, Help & Troubleshooting and Genera

My battery life is very inconsistent lately. Yesterday my phone lasted all day while doing more then I usually do. I used WiFi, texting, calling, browsing and even streamed NFL Sunday Ticket for more than using 3G/HSPA+ and the phone lasted all day from morning until I was ready for bed. I should also mention that auto sync and background data was also on. Today I barely used the phone and my battery was at 20% from 8am to 12pm.
I'm using setCPU and AutoKiller.
mattc 1.7 RMNET
radio 2.12
WINMO Energy Rom
Is anyone else having issues like this, with the inconsistent battery life? Any ideas on what I should try?
Thanks!

Yes there's a thread on the android developers forum where everyone is trying different things to lower the battery usage.

[Q] JI6 OTA Poor Battery Perfomance

I have read these forums for a long time but this is my first post. I recently updated the JI6 via the official T-Mobile over the air method. I have been on JI6 for two days now and have noticed that my battery life is terrible. Usually I am able to make it through a day of average use without any problems and I charge at night. Yesterday my phone did not make it through the day and it was a low use day at that. When I got home from work I started charging the phone, before bed I unplugged it and figured it would be no problem to just leave it in standby all night, my previous experience was that a night of standby only dropped my battery by a few percent. When I got up and looked at my phone before leaving for work it had already dropped to 21%, I looked at the battery usage statistics and found that Cell Standy and Phone idle had leapfrogged over display which is usually the biggest draw of power and were now using significantly more power than even the display. Also I do not live in an area of poor cell phone reception so that could not have contributed to this.
My phone was pretty much stock besides being rooted to run the WiFi tether. My wife also has the same phone and she said she is experiencing pretty much the same thing since the JI6 update.
Below is the list of the top 4 batter using processes were on my phone and their percentages.
Cell Standby 41%
Phone idle 30%
Display12%
Android System 9%
Is anyone else experiencing similar battery usage since the JI6? Is there a known problem with this JI6? Has T-Mobile or Samsung acknowledged this problem? Any suggestions for fixing the problem at least until Froyo comes out?
Perhaps others can post their experiences with battery performance post JI6 here as well so we can get a consensus.
The radio in JI6 is stronger than previous versions to help with reception. That being said, it drains battery more. However, the stats your provided seem to point to you having apps on your phone that are pulling internet information too often. My cell standy or phone idle is never higher than my display and I do use widgets and apps that update a lot.
There just seems to be a bug somewhere that causes random drain, I've seen what people are saying about and I pulled the battery, it stopped draining for me until I guess I trigger it again.

I do have some apps that are pulling data down from time to time, but I have been careful about setting these apps to not update too frequently. Also last night I specifically went in and closed any unwanted running apps, I think the only apps I left running were Seesmic, K9 Mail, and Gmail.
This thread is precisely the reason for why:
a) I finally registered to xda-developers for support
b) I decided to root my Vibrant
I received the JI6 OTA update around 5 AM on Wednesday, thinking *oh sweet this must be 2.2* I didn't hesitate to install it...the first 24 hours after didn't seem to show much signage of battery drain, but by Thursday morning things seemed...off.
6:00 AM - 100% charge, fresh off the cord
Around 11-noon - 15%, low battery notification pops up
This was by far the quickest drain I've seen, and even though I've only had my Vibrant for a month...right out of the box I was getting spectacular batt. performance with light-moderate use + wifi + sync, lowest brightness*(auto off), somewhere around 24-30 hours.
My initial reaction was to reset to factory, only to discover here that it did absolutely nothing to remove the JI6 update.
Now, post-root I've been reading through similar threads about the OTA effects and finding all types of tricks to extend the batt. life. Today the battery hasn't been as bad (with nearly everything off...sync, intervals, gps, blah blah), lasting around 11 hours. Not sure if there's any fix in sight, though I'm not really anticipating it reading how the cell standby / baseband is cranking out more power and in effect more juice.
My battery is about the same as before, getting 24-30 hours out of normal use. I'm currently 14.5 hours unplugged sitting at 42%

Flashed JI6 via Odin, and my battery life has sucked since. Talking on the phone kills it especially fast. I talked for about 45 mins yesterday morning and the battery gave out after 7 hours. Today it at least lasted 12 hours, but that was with pretty much everything turned off. Anyone flashed back to JFD? It's not like JI6 brought anything to the table.
My battery drains while idle after the update. Yet my wife's phone battery is fine. Hers is stock and mine is rooted with mobile AP flashed. I even reconditioned the battery.
Tonight I decided to flash bionix 1.91 rom to see if that would fix the battery drain issue. So far it's looking good. I'll know better tomorrow after a full charge.
JI6 installed Media Hub, right?
Sprint Epic users found that when Media Hub was installed on that platform a couple of revs back, it loaded a DRM background service that is constantly running even if Media Hub is never used. It is now pretty standard practice among knowledgeable Epic users to stop the DRM service whenever the phone boots. Many rooted users go further and delete it.
Vibrant users might try the same methods to improve battery life.
My battery usage has been fine. I installed through mini kies though rather then the ota.
Sent from my SGS Vibrant.
It totally sucks for me. I have tested it throughly this past week. Ran JDF and left it idle over night, barely lose any battery life. Update to JI6 via kies mini and lost 30% over night while i'm sleeping. I also tested the various versions of JI6 posted on xda and all of them give me horrible battery life (losing 3-5% per hour doing nothing).
I'm flashing the JDF modem file on the JI6 from kies mini. Will report back...
Again I'm completely confused here. Running stock JI6, went to sleep last night at 24%, woke up this morning at 21%

That makes no sense, if you're on WiFi it wouldn't be the cause of this. Are you sure it's set to be on WiFi 100% of the time/when the screen is off?
That's ridiculous, something is awry

Switching to bionix 1.91 stock kernel solved my idle battery drain issue. I was losing ~4% an hour and now with bionix it's not draining. Unplugged the phone this morning at 100% and an hour later it was still at 100%. Same as before the JI6 update. I'm happy now. Bionix is smooth as butter.

After the update I got horrible lag and bad drain. I'm talking 4 hours on average usage.
Sent from my HTC HD2 2.2 Group using XDA app
Does anyone else see the irony or possible logic that Samsung gave us a stronger modem that uses more power and a new task manager to monitor what else is running draining power with the Ji6 update? Granted there are better task managers for root, but kinda clicks in my head.
Also after all my settings have been checked, apps, wifi sleep (used OCLF), widgets and internet, syncing frequency, wallpaper etc. I used Rom Manager to recalibrate my batteries. I thought that the battery data might have been wiped during the update and at first my phone behaved like it.
All good now. I'll never have the stand by of a flip phone, but it all seems reasonable. I use my phone a lot, a real lot. I go through 2-3 charges a day, mostly 2. I have extra batteries also. Stand buy time almost seems better, but I have not recorded data and I have made many changes.
Theres a good thread a dude put up in the Vibrant general section about his anal battery saving habits, he uncovered more ideas and things I didn't know. Hes admitedly extreme put its a good read. Also a couple of threads on how to recal the battery, some disagreement there so I did not chime in here with specs.

Tips or What is in your opinion the best rom for battery life for the HD2?

I have searched around the forum but cant find any recent discussions on what is the best HD2 rom, i recently used CoreDroidGBX and i find the battery life to be pretty good on that (Lasts me till end of day with light use (Light use being screen on about 2-3 hours out of that day) End of day being 7:00 Unplugged Low bat around 5-6:00) But i see about 300-500 mA useage when im actually doing anything on my phone(But just like 2-3mA when its off and i disable data)
So i keep experimenting with different roms and i am wondering what you guys have experienced the best battery life with on your HD2's.
Also i have to manually toggle off data, is there a app to auto do it, like automatically whenever the screen is turned off? I had my phone on battery nearly 24hours (Although i was on my laptop and only used it for like 20 mins of phone calls and a few texts) but still a real full day was awesome

Coredroidgbx? There is a Coredroid series by Sergio and a hyperdroidgbx by Pongster. Both get rave reviews for battery. I run hyperdroid and I get 18 hours of normal use no problem. If you consider watching YouTube and flash video all day normal there is no rom that will last doing that.
Do you prefer a sense or a non sense build? GB or Froyo? CM7 or ASOP?

I would say u need to check some nand built on your own as different phone respond differently to rom built. hyperdroidgbx and rafroid hd 4 are good option to move ahead and check
+1 agree.
Thoese are my favorites too.

tried using CoreDroidGBX before also..
smooth... but battery is almost the same as other builds..
In my opinion the best battery life was in unofficial nightly CM7 by charsingh (1-3mA in standby). But due to some issues i had to switch to Typhoon CM, battery drain is notably higher (6-10mA standby) but for me it is the best ROM ever.
I think that the functionality of the ROM is litle bit more important than small diferences in battery drain.
Motoman234's Moto-MyTouch4G v3.3
Nand build and the best I've tried so far. I can get 2 days with light use (text and moderate calls) and a full day with fairly heavy use ie: web for 1-3 hrs and 1-2 hrs of various games along with calls and texting. I call my family on the east coast frequently and a 2 1/2 hour call is not unusual, loose maybe 20 to 25percent on the call depending on my signal. Great rom, a chef that responds and helps, again nand build. totally functional for me no issues flashed 4 different phones to it so far! .
I as a rule, leave wifi on always and use bluetooth, location, and background data only as needed. Blue tooth and background data will suck the juice right out! Still, if I forget and leave those on I can still get a full 10 hr day out of a single charge, provided i dont spend hrs surfing.
+1 for Cyanogen Mod 7. I tried a lot of DesHD builds but CM7 has the longest battery life by far for me. One charge lasts me about two days with light use. With all DesHD builds i never made it past 24 hours. Usually even less than that.
Furthermore CM7 is just beautiful, especially with cyanbreadX
i'm on rafdroid 4.0 and unplugged this morning at 8 am and the time now is 5:30 and i'm at 60% with moderate use and wifi off.
i will say though that if i play bubble blast 2 that thing sucks the battery like nothing and i'm not sure why. it's amost 1% battery per min i can feel the phone get hot from use.
Running cm7 unoficcial right now and seem to be getting good batter life, but I have seen it actually use 700mA (srsly) when just charging ..
But can idle forever. But lost 15% in an hour during lunch...

I just put HyperDroidGBXv7 on my phone a couple days ago and its been great on battery life so far. I unplugged my phone about a 12hrs ago and its at 74%, averaging about 3-4ma on standby. No classes today, so I've only used it lightly today for some quick wifi browsing, short gaming (Angry Birds), and about 30 texts.
Ok been trying cm7 and for some reason when actually using my phone I seem to get a steady 535mA battery useage, any suggestions on fixing this?

I'm using IamGPC's Pure Gingerbread, although hard to get since he moved his updates from XDA, but I have -2MA in standby. It's a 2.3.3. clean Android version.

Battery Tips?

I just want to know what I can do to improve my battery on CM7 nightly 32. I'm at 21 hours now and almost dead. Yet I see people get stuff like 2 days and 10 hours... I have tasker and the only profile I have is when the screen goes off it turns mobile data off (not sure If it works so I also use apndroid). I NEVER use wifi, bluetooth, or high brightness. I do however have gps on so in case I lose my phone is lost or stolen I can track it. So there's no way I'm disabling that. I have tried juice defender but figured since it can't effectively disable data for 2.3.3 I saw no point in the app. Any tips?

21 hours on moderate use is great battery life. 12 hours is usually the measuring stick for smartphones, less is bad, greater is good.
Don't know who you saw getting two days plus, but they are either not touching their phone or have an extended battery.
Sent from my T-Mobile G2
Best way to extend battery life is to get an extended or high capacity battery. I just got the Mugen Power pack, not the chunky one, and im in the process of breaking it in.
On my stock battery i was getting about 17hrs of moderate use. Almost no talk but alot of texting, engadget and youtube mostly on wifi with gps always on. That might give you an idea, plus, there are countless battery related threads on here.
Will post back in afew days after my Mugen has cycled afew times.

I have 4 stock replacement batterys and never plug my phone in to the charger. When my phone is at about 5% i just take one out and pop the next one in and charge them in the wall... I know its not the answer you want but I never have a problem with battery life lol
I would agree that 21 hours is great battery life on this phone. I can get a week of battery life on my phone if I put it in airplane mode and stick it in my desk drawer =P
Not sure how big of an impact the tasker profile has. Unless your screen is off for long periods of time I would think that it might harm the battery life because every time you touch the device, it has to 'search' and connect to the tower again.
You can try running the phone at the stock CPU speed to see if that has an improvement on your battery life. I currently run the same 1017/245 as you with a screen off profile set at 245/245.
For me, as long as I can make it through a day's use, the battery life is fine. With moderate use I can go about 15-18 hours and heavy use I'm at around 12. The car charger in those cases is a life saver.
Bottom line is, battery life really depends on your usage habits. Those people getting days out of their phones likely aren't using them very much...
well i have setcpu set at 806 max and 245 min. screen off is at 245/245 and on powersave governor. other then that its on ondemand. i also have profile set to reduce the CPU based on battery. I have it set to <101% its at 806/245 , <41% its at 768/245 and less then 25 is 368/245. i realize that these are low speed but i hardly ever get lag and i use it for everything, music, video, youtube, internet, twitter, facebook, xda , and a here and there gmail. i guess if im getting exceptional battery life... anyone want some tips?
I find the more variation I put into profiles on setcpu, the worse my battery life gets. Theory - it is constantly watching and making changes based on your CPU needs and battery. So I have mine set to 1113-1113 performance, 245-245 powersave screen off, 245-245 powersave 45degrees+ and for your mobile data, try just having a widget to turn it on and off as you need it. You probably don't need it on everytime you turn on your screen do you?

I find the stock battery to be not that great. I bought the Chichi batteries way back in October (when they were still considered cheap) and theyve been great. I havent really done any new tests since October, but back then (before I had a data plan) I was getting atleast a day and more (from 100% to dead) with moderate usage.
I'd look for a high capacity battery, though they seem to be expensive now.

My mothers g2 is rooted and running cm7 nightly 29 or 30, I installed it last week. I asked her today for the first time how the battery was after a week. She is using an aftermarket 1800mah battery, wifi only at home, she was almost at 32 hours and had 39% battery left!!!!
Not sure of all settings but i put it on 1113mhz, on demand with min 368, autobacklight, wifi only at home, bluetooth is always connected and on. Talk is about 70% of her usage overall. 4 gmail accounts. I did not install set cpu at all. I even stopped it on my phone because it didnt help me one bit.
Not too shabby. I was at 57% with some texting but a lot of gps usage for latitude and wifi always on even when not at home.

here is what i get out of a day (battery consumption for specific tasks are mentioned in percentages measured using juiceplotter)
wifi on constantly
display set to 24% brightness
background sync enabled (google, weather 6hrs, whatsapp and facebook once a day)
45 min video (rockplayer no h/w decoding) 15%
1 hr browsing+chat 15%
30 min calls 6%
20 min music+chat 5%
20 min general usage 5%
1 hr flash streaming 15%
24 hrs standby 24% (@ 1% for every hr of standby)
15% battery remaining after 24 hrs i.e. low battery warning.
i disabled the use wireless network option under locations and always on mobile data
and get much better battery life, also i use wifi constantly when available (which is 90% of the time), it is much better for battery life than using 3g or gprs/edge.
pretty amazing battery life IMO i am very happy.
So i have cycled my Mugen 1800mA battery acouple times. on average, i'm able to get about 27hrs of heavy use. Here are some settings as a baseline:
Always on Data
Wifi always on
Auto brightness
1GHz clock speed
massive amounts of text use
massive amounts of screen on time
will report back in afew days time after some more cycles.

I'm wondering the same thing... the Desire Z only comes with a 1300mAh battery... My previous phone had a more powerfull battery (2100mAh) and that was an older model WM6 smartphone (which was rubbish on power savings) and it would outlast the desire Z... Even after two years of extensive use, the old phone's battery is better then this phones brand new battery
I've been unable to find any official HTC batteries for the Desire Z which pack more juice...

I am in the process of 'breaking in' a new 1800 MuganPower battery. Fits perfectly with no mods needed.
It should take a few more charges etc to settle down, so things should theoretically improve.
I pulled the plug off charge 6.5 hours ago.
I have it set to use wifi when at home, and 3g for the phone connection (I have a 3G femtocell at home).
When I leave my home area, it switches off 3g and wifi and drops to 2g.
I have made a couple of 2 minute calls, checked my emails and twitter, and was out of the house for say 1.5 hours earlier.
I have had a couple of texts to which i replied.
I am on 95% charge now, and pretty pleased with that.
I've got the same mugen battery, and get through a full day easily no matter what I do. Screen full bright, wifi always on, some internet, games, gps.... etc. Only 7 hours of battery to me sounds terrible.
since my last post, i havent touched the phone at all, and its got 66% charge -__- i seriously need a better battery, may buy the mugen, would you say they are worth it?

Sent from my 'SilverBullet' HTCDesireZ running CM7
mobile standby 33%

im surprised its been 10h 15m and im still on 58%
the battery seems okay when not touching the phone, as i have only checked facebook for 2 minutes, and sent around 10 texts (been playing football)
looks like imma turn off wifi when not using it from now!
When I first got my Desire Z when it first came out I was pretty disappointed in the battery life. I tried programs like juice defender and minimized every possible battery sucking option I could find. I could maybe get 12 hours of use out of it so I bought a 1800mAh MuganPower battery which gave me maybe 15 hours instead. Pretty poor I thought but what more could I do?
A couple of months ago I finally did a factory reset after encountering a lot of frustrating little bugs, some of which had been around since the phone was new. Since then not only has my phone worked a lot better and faster, but battery life is MUCH improved. My phone now consistently lasts 24 - 30 hours with the same usage or more than I was using it before. So obviously buggy software can make a huge impact on battery life and it's not something you are going to be able to easily discern as to what program(s) are causing the problem.
Hmmm im not sure then..

Battery seems ok, still going to invest in a better one though, as using the phone for games or internet heavily drains the battery, whereas standby seems to be quite good, but need to turn off wifi. I will see how it fairs tomorrow, and post a picture.

28% for wifi seems really high. I always have wifi on and it only takes up 6%.

(Q) nand android and battery life?

So, what's the deal with hd2 with nand adroid and battery life? Is it poor? I mean I still have to do a full day test I just got my hd2, but what is to expect? And there's any extended batteries that you guys could recommend

It really depends on what build you use, the kernel it's based on and how you use your phone.
I use my phone all day with internet connection, I get about 13 hours out of a charged battery, that's with WiFi almost constantly on and using Whatsapp, Facebook and browser a lot and beside that the occasional game.
This is on Hyperdroid CM7.
With less use of the phone and turning off the WiFi connection I can get about 25 - 26 hrs on a fully charged battery. If I really try hard I can get 2 full days out of the battery (that means almost no use of WiFi and turning off the data connection as much as possible)
Mind you this battery is 1 year old and abused (quick half charges every now and then)
The battery life of the HD2 isn't the best. But with a good build and a program like SuperPower or JuiceDefender you can get pretty good results (atleast a full day of using your phone.. which to me is exactly what I want.)
I personally do not have experience with extended batteries, I'm still on my stock HD2 battery
So far on hyperdriid the battery is been not really good, is only Been maybe 2 hours without wifi and screen brightness all the way to thebottom and is already at 76% not good at all lol I will let it drain and try again tomorrow.

Like bever86 said, it depends on which build you use. And unfortunately you can't know which rom has the lowest battery drainage without flashing and checking out yourself.
Here's some of the rom's i tested:
UltimateDroid 3.3 - was okay. I got at least a day with it.
I tried some version of MIUI which was pretty bad. It didnt last from 8am to 1pm.
WindowsPhone7 - was okay too. Pretty much the same with the UltimateDroid.
Now I'm using SENSATION XL V 2.5 stock ALL IN ONE. I just flashed it yesterday but it seems very good. I used wifi to download apps all day and it hasnt even dropped to %60.
Right now I'm with hyperdroid and dorimanx.... its awful... if I use the phone for 20 minutes idk, browsing with 3g the battery drops Maybe 15 % is alot even. With screen with minimum brightness and not overcllocked.... I don't know what to do, I don't have money for a bigger battery and I could sell the phone but nothing good is available for under 200 used. Uhmmm what to do what to do...

I Easily get 14 hours of pretty heavy usage on hyperdroid, with an extended battery I can get 3 days.
It depends a lot on how you configure your OS, how many apps are auto-sync, signal strength and the health of your battery.
Last one can't be underestimated, your battery losses about 10% of capacity per year under the best possible conditions. In realistic usage, your battery is junk after a couple of years.
I run my phone OC'd with 3g and auto sync. Before I replaced my battery half an hour of browsing would drain about 15%, same setup new battery, the drain is about 3%.
