Hi everyone. I had NAND installed on my HD2 now for about a month and a half. One of the things that I haven't seen on my phone is better battery life. This is the first phone I have with a data plan so I'm really not sure how much of the battery drains with data. Here is my daily routine. I charge my phone overnight, by 11am-12pm my phone is just about dead. I put it on the charger until about 4pm; usually it's fully charged by then. By the time 10pm comes around it's almost dead again. Doesn't seem like good battery life to me. Someone please let me know if I'm missing something.
Thank you all!
Depends on what you're doing with your hd2.
If you spend a lot of time on the internet with either wifi or 3g, then that drains battery pretty quickly, as with any device. Playing games or watching videos is the same thing, although to a hiigher extent with games. Keeping the phone screen on is also one way to drain battery quickly.
You should install current widget and monitor your standby times, etc. In standy by, your phone should be consuming 4~6 mA ideally.
If you want to monitor your battery usage, first download and install CurrentWidget, enable logging while the phone is on standby to see your standby usage.
Second, need to check battery usage on standby after a call, there are some kernels with a known bug that prevents the phone from going to sleep, consuming 60ma on standby.
Third, Do a battery calibration, it does help a lot if you have never calibrated your battery, android tend to mess up battery reading after a while of not being calibrated. There's a thread about in on forums, search for it, REALLY good info there.
Fourth! check out if you are in a zone with crappy 3G, if the phone has to turn 2g/3g off and on too often it drains battery like whoa.
Fifth, take note of max and min voltage readings with CurrentWidget, your battery might by wearing out (should be maxing at 4.2v and min around 3.3v - 3.6v depending on kernel).
Another thing, before your phone dies, check out battery usage on Settings, see if any program is eating your battery, and check out how long has your screen been on, and post it here
I've always had WAY better battery in Android, even SD, than WMo, MSN/push email killed battery in WMo in about 6 hours, without use, just standby. Android get up to 4 days in standby with Gtalk/Gmail/Exchange Mail, all on Push, along with weather and twitter. With hardcore usage, the battery last between 6 and 7 hours top (Screen on for 4-5 hours), while Gaming, it wont last more than 4 hours (CPU at 100%, Screen always on, GPU at 100%, Brightness 100%).
Normal usage (between 40 mins and 1 hour of Google Maps with GPS on, between 3 and 4 hours of music thru Bluetooth with my car, 10-15 mins talking, about 20-30 SMSs and quite a bit of Gtalk) it makes it thru the day, lasting about 12-14 hours.
Such a low battery life is probably cause your phone is not going to sleep, it should be at 2-5 mah on standby.
Hope it helps
I can play an hour of pokemon (gba rom), listen to pandora whenever im in the car, surf the net for an hour or two, and with a total constant usage of about 5 hours, and at the end of the day ill be left with 30% battery still.
If I don't use it often it will last 40 hours +.
Maybe try a different nand rom?
Im running hyperdroid nand
Zephyrot and kangpeter, Im jealous of your battery life. I'll try what was posted. Thanks for the replies!
i just wanna know how much people has battery drain on GingerDX (all version)
pick your Polling here
and tell us why your battery drain
Gdx is really sucking my battery,but u can install the supercharger script for longer battery discharge
Sent from my X8 using xda pertamax
wow
a lot people have battery drain
Yesterday, I've observed huge battery drain during the day .. about -15%/hour while doing some basic tasks on the phone (email, IM, inet browsing). Later, I've found out, that auto brightness was set way too high and had to manually decrease the brightness levels. After that, power consumption dropped to about -5-7%/hour while doing the same tasks as before. The display value in battery use menu also dropped from 70% to 30%.
The idle battery drain is OK... about -1%/hour with only GSM network on.
IMHO if your x8 battery is draining too fast, check doixanh's FAQ and then check the brightness levels...
Hi,
I'm afraid that the battery consumption is not related to GingerDX itself but to the additional software and phone usage.
In order to improve battery life in GingerDX do the following:
1. REMOVE or freeze Google Maps (ownhere). Use a different software instead (like maverick pro 1.94, which has google maps enabled and it is not consumig your resources)
2. Also, you may want to remove dsp manager (use the built in equalizer in your favorite music player instead).
3. Disable data MANUALLY. Use the built-in power widget to disable mobile data when you're not using it. Don't use automated 3g disable software because it will drain your battery too.
Your battery should last for 2+ days with normal phone usage. No need to mess with the good working autobrightness, you can leave it on.
FroyoBread:
1d 7h 29m since unplugged - 71% battery left
That's pretty good, isn't it? (Sorry for "offtopic")
hello everyone, i just think that battery callibration and some apps freezed is enought for the battery drain... some apps like gmail, maps, maybe market..
for me the battery drain is normal
i´m using gingerdx V011
Wow Still battery drain use this Doixanh Suggestion
Clear battery stats in xRecovery
Freeze unused services (like Email, DSP Manager, Maps). This is important.
Don't set brightness too high
Don't install too many unused apps.
Turn off WiFi, 2G, 3G, GPS, Bluetooth when unused
Turn OFF LED Succession. It's turned of by default, but maybe there are some people still leaving it on.
Reboot after you listen to music. Music service caused battery drain (in the past) for me, even when I stopped listening to music.
Hi. Im using GDX v012 and I don't know if I'm having a battery drain..... in last night battery drop about 17-20% in standby... with all the things off (wifi, data, gps).
So, i went to check the graphs and i noticed that the cell was active during all night....
somebody can tell me why?
and second, maybe the battery drop a little faster because of my signal strength.. but not so fast....
GDX v012, DSPManager manually pushed back into the system and Google Maps + Streetview from the Market (can't live without it); apart from the apps I already had installed.
Depending on the usage of my phone (calls, WiFi, GPS) I get 1-3 days on a charge.
Mind you, I don't use the phone for listening to music or watching video [EDIT] or gaming; that's where my Liberty Tab G100 (mod-flashed into a Iconia A500) performs a whole lot better thanks to the Tegra 250 chipset and faster CPU [/EDIT].
I did a test and found that it consumes my battery is the signal strength that is weak in my location....
when i put my phone in airplane mode during all night, battery has not decreased even 1% ...
i have many apps installed, including maps etc etc
GingerDX v012
Yea, I kinda just upgraded to GingerDX v012, from v010. Somehow I missed v011.
Anyway, I realised that v012 drains my battery a lot more than v010. I wonder why.
Just today, in 3 hours of idle mode, my battery drained from 80% to 60%. That's alot o.o
Any tips on how to reduce this battery drain problem?

loving the ROM, but my poor battery!
This is my first post on this site. doixanh, you are a legend for making this rom available to X8 users. Its smooth and pretty. stock eclair can go in the rubbish with no reservations. When I first discovered just how limited it was I regretted buying my phone. Then I discovered froyobread (which I used for 1 day) before updating to gingerDX v13. Stoked!!!!!!! My battery drains pretty badly though. I have quite a few apps installed and use live wallpaper so I guess I can put up with it. I need my koi carp dammit! lol
My battery was draining 20% to 30% an hour on idle mode with bluetooth, 3g and wifi off. Turned on Airplane mode and now it drains around 2%-4%.
Any ideas on how can i improve the battery life without having to turn on airplane mode?
displays drain my battery 90% omg
when i check what uses battery it indicates 90% on display
my phone only last for about 8 hrs doing nothing just in idle mode
i follow all the instruction but it failed (

I tested it and got no significant results.
The change in values doesn't seem to improve battery life...
Using GingerDX 013, so far no battery drain. Yet i have noticed, that it's the cell standby that uses the most power. Although it drains 1% in 2-4 hours depending on quality of signal in my region. Usually everything's off and i have the supercharger v8 script installed. Also applied the smartass tweaks to save battery time as well. And i kill all unnecessary processes after using apps.
small update: Current uptime is 3d 22h as of this point and i still have 21% battery left. And i've drained over 15% when i was meddling with the supercharger settings. Otherwise regular use - phone calls, messages, some tinkering and wifi usage.
status update: standby was 4d 14hrs to 6% including the 15% drained when trying to set up supercharger. So it is possible it can do 5 days with small use and 6+ without any use at all.
Hey guys i just recently installed American Android rom onto my HTC hd2 And while i love android and it works almost 100% flawlessly My battery life has suffered alot.. with windows running i can get over a day of use on standby. With android running i get around 12 hours if im lucky. if i make calls and use it it drops to around 5-7 hours. I have juice defender installed wifi bluetooth and gps off. I cant think of anything else that could be causing it the only other thing if it even matters if My 3g coverage goes on and off all day but idk if that would cause the battery to drain. Any help or tips on the issue would be greatly appreciated.

You could easily have used the search button and not have had to create a post like this :/
Refer to this video for more info about that.
Download CurrentWidget and check your battery drain on standby, it should be around 4mA. With screen on, there isn't much you can do really other than to lower the brightness etc.
my stats
i downloaded current widget but im pretty new to this so the stats when im on the home screen are 152ma 3.762 V it randomly spikes to 550 then back down to 150. idk how to check the screen MA itself ... My Android system is 30% , cell standby 24% , phone idol 17% , voice calls 15% display 10% mediaserver 3% music 3%.

150 is decent for screen on (at least it is for me, may be crap for others) and to check with the screen off just turn the refresh interval to something like 10 seconds, wait a minute or so to let it settle then unlock the screen and look immediately at the battery drain. If this is higher than 10mA (at the very most) it isn't good at all. Try with airplane mode on as well, would lower the battery drain significantly.
How much battery life are you guys getting on your Tab Pro 8.4? I bought mine couple of days back and I felt it's disappointing.

What bugged me was the disappointing battery life when the screen was turned off (not completely powered off of course). Even in airplane mode it would die in a day or two just sitting around. Battery stats showed Android System and OS were killing the battery. I never figured out if there was a setting or something to fix it.
Instead I loaded Cyanogenmod 11 on it a week ago and now it uses only 3% of the battery a day when I'm not using it. I don't miss any of the Samsung extras.

Something must be keeping it awake. My tab has excellent standby battery life.
Doesnt lose more than 5% in a day. I do have the setting to turn wifi off when in sleep mode though (unless plugged in)
Battery life on the whole varies. Video watching through the stock video player drops about 10% an hour. Surfing would depend on your browsing habits. Gaming drains close to 20% an hour. Pretty standard. That along with the excellent stand by time means I get about 2 days of use on a charge.
Every day at work telephony, internet, email, IMO 24hours, 24hours Bluethooth Gear 2 connect. Dinner consists of my tablet battery 55%. For me life is great. My tablet root and frozen Samsung Apps (Bloatware) ... XDA .... Try the Nova launcher from the Play Store to Improve speed. Set it as your default launcher then Disable / Turn Off;
Flipboard, MagazineWidget, S Voice, Samsung Apps, Samsung Apps Widget, SapaMonitor, Screen Saver, World Clock, and (Hancom, Office for Android Share, Hcell, Hshow, Hword, Updater, Viewer Launcher, and Widget) if you do not plan on using it.
We will be adding Quadrant test 24,000 points on the original ROM.
Play google baterry doctor.
Battery life is good its an app thats draining the battery.

Yes it was using as much battery as watching a movie with the screen on. Something was terribly wrong with it. I think this behavior started after a software update I got from Samsung.
I turned everything off including Wifi and it was still eating the battery while sitting there with the screen off. I have never seen that with any Android device I've ever owned.
But I'm happy with Cyanogenmod. Battery life is outstanding now.
My battery life was mediocre, and then I put cyanogenmod on, and it went to dreadful. With the tablet at 100% and OFF, untouched, it would be 20% down in 10 hours. In contrast, my iPad loses maybe 3% in that time, doing the same thing - tracking email.
I ran a wakelock tracker and noticed that Exchange Services has it awake about half the time. The total time. Like in 10 hours Exchange had it awake (with screen off) more than five hours. Effen ay. Something is seriously screwed up with how Cyanogenmod's Exchange talks to the two Exchange services I use. Switching from Push to "5 minutes" has helped significantly; Exchange is still the worst culprit, but now only by a factor of four rather than a few hundred.
Ideally what I'd like is the new Exchange apks modified to prevent admin and fixed to be less wakelock intensive.

Cyanogenmod has their own version of Exchange?
Our Exchange servers at work are ridiculously slow and unreliable. They can take two minutes to return your mail which is a major drain on your battery if it's set to check it every five minutes and you get a lot of mail. Sometimes they'll just stop responding and leave you hanging. The IT people just tell you to keep trying and you'll get your mail eventually.

Dunno.. 7-8 hrs I guess. Screen on time really doesnt mean much without any context.
I can get 12hrs+ watching videos on 20% brightness. I can kill it in 4 hrs playing games at 100%.
Like I said, the standby is excellent. Drains less than 10% in 2 days. So for me, I have about 90% to use over 2 days.. and from my experience,
video drains less than 10%/hr
gaming ~20%
reading books drains less than video.
General surfing, mails, social networking uses between 10-15% depending on how you are using it.
My brightness is usually around 40%. Goes up rarely when I'm using it bright conditions. Goes lower when I'm reading late at night
Should give you an indication of what you can expect from the battery depending on your usage..
Mine drains about 10% per hour while constantly using the device for light tasks, such as reading, web surfing, and watching some YT videos here and there. That increases to about 15%/hour when I watch movies. So after watching a 2 hour movie, I expect to see about 70-75% of battery left. Now if I'm listening to music for an hour at the gym with the screen turned off, it only drains about 3%.
At first, I thought that was pretty mediocre and felt disappointed. But I've taken my tablet with me on many trips and never had it die (usually just close to 20%). I rarely ever use my external battery pack. I know this will vary depending on how long the trip is and how much you're using it, but I'm just saying that it meets my needs despite having a lower battery life compared to some other tablets. I do all I can to extend it, but I don't have to constantly watch it.
Last night I charged the tab 100% and with Wifi off (sync for 1 min every hour. )
Today the battery is at 71% - On battery 13hours - 44 mins
27% Android OS
24% Google services
13% Android System
8% Onscreen time - 20 mins
Should I flash CM to fix this?

CM won't fix that. Install Better Battery Stats or Wakelock Detector to nail down the precise problem. If you're using them, it could be Exchange Services or Google Drive (yeah, that turkey wakelocked me to oblivion!), at which point you at least know what to attack.
You can find BB on XDA here and WakeLock Detector on XDA here, both are also in the Play Store.

Google search with 23 mins of wake time and Gmail with 6 mins.
Currently Deep sleep is 14 hr 26 mins. Total time is 17h 5m. Awake is 2h 39m. Screen on time - 27mins.
I added the google now widget a couple of weeks back and that caused some wakelocks and overnight battery drain. Removed it and didn't have the problem.
The battery life is pretty good for me. Was out a lot, so had wifi off for large parts.. watched videos (from device), read some books, played some Asphalt (not much.. around 30 mins) and some browsing/mails..
Got 11 hrs screen on over 2.5 days and still have 15% left.
Yeah was indoors so the brightness was never over a third (~30%) and reading books really doesnt drain much battery(especially if its at night and you turn the brightness further down)..
I'm not saying people will get 10+hrs screen on with their device and usage constantly.. 8hrs would be realistic.. but the point is, the battery is a lot better than I had originally expected.

I have this same problem - except my GTP is 100% stock, unrooted. I can go into Settings/Battery to see that Exchange Services is chewing my battery. It will die in less than 24 hours, even if I don't use it - as long as it has a WiFi connection. I think if I turn off WiFi, it will stop attempting to sync and the battery will last "normally". I don't know for sure, though, as I haven't tried. I'm not interested in a tablet with no network connection or even without my email.
I'm going to cut a VERY long story short (at least, here) and say that I have spent several hours logging the ActiveSync traffic between my tab and my server, poring over the logs, and I have identified the problem. It's one particular item that is failing to sync, which causes the tablet to retry the sync every 1 second. The sync failure causes the server to log an internal server exception every time - despite the ActiveSync requests from the tablet being correct. I also found a Microsoft KB article that appears to address this exact problem, and MS has a hotfix available for it.
I have talked to Tech Support at my hosted Exchange provider and they have confirmed with their operations staff that my server does not have the MS patch that is referenced in the KB article installed. Unfortunately, they are giving me a bit of the runaround on installing it. I only have one mailbox hosted with them, so I have no pull. They sound like Verizon. "We have to thoroughly test this update in our lab before we can install it on your server." And "nobody else has reported this problem and we can't put too much time into a problem that only one user is experiencing."
So, I am now just waiting for them to install it on my Exchange server and see if it really does fix the problem for me. If it does, I will be posting about it on XDA and the AC forums, as a Google search showed me that a lot of people, with a lot of different Android devices, have this same problem and nobody seems to know what's really going on or how to fix it. I will try to remember to post back in the GTP General subforum specifically, too, so stay tuned.
My battery life seems to be getting better as the battery gets some more charges on it.
Sounds basic / silly, but i simply put mine in battery saver mode and that made a big difference with little effect on performance
6h 37mins 56s on battery
Android OS 41%
Android System 12%
Google Play services 10%
Screen 5% (24mins screen on time)
I am currently at 49% after taking my phone off charger at 100% 6hours ago. What is going on? As you can see screen on time is only 24minutes, yet i've lost more then half of my battery! I have email to sync every 4hours so I know that can't be it. What can be causing such a massive drain? I don't use Facebook, Twitter, Instagram, so Im completely lost as to why my battery is draining so rapidly.
I've attached 2 photos.
