After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!
did you read anything before you started this thread...........
yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem
did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues
drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.
thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.
nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.
what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.
alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2
such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .

Hello there,
I would really like some advice - my battery is draining like water. I'm quite convinced it is the regulation of the unit; I bought a 2400mAh battery replacement and it lasted ages on first go, but then my G1 started draining stupidly fast after I'd recharged it. This also happens on the stock battery too (buy even quicker!). I'm convinced it is the regulation because a) I've never had battery problems previously and b) the battery meter starts at about 26% when I plug it it in (after the phone shuts off from it being dead and I then plug in the charger).
I actually have a bricked G1 that still charges batteries, so I thought I'd do an overnight charge on the battery that way, to 'remind' the other G1 what a 100% battery is like, but that didn't seem to work either.
Can someone help? Is this a known problem? I would really appreciate any advice.

Things that cause ridiculous battery drain;
Backlight, keep it at no more than 30%
Wifi - turn off search for open networks,
Gps - wow does this drain

GPS doesn't really drain battery unless it's actively being used...at least not on my phone.
You can also try disabling 3G if you're not in a 3G area. It will keep trying to find a 3G signal, which really drains battery.
For the record, I have a stock battery that I get ~13-16 hours on from a single charge... my backlight is at 40%, GPS is always on, and I use wifi whenever I want to surf the web and am near an open network.
OP...if your battery is lasting you only a couple of hours, then I'd try to reflash your ROM. Might help...
Wow 13 to 16, I am lucky if I get 6 with 30% backlight, and wi-fi and gps off, I have always gotten that on ever rom even stock with no widgets, you are one of the very few with good battery life cause I have seen many complaints about short battery ranges

Yeah, that's on a normal, moderate usage day. If I use it heavily, with a lot of wifi and web browsing, then I'll get around 10.
Maybe your battery needs to be replaced... could just be old and not holding a charge properly.
It's 2 months old, has done it from day one, I also have another battery that does it too that I kept from a previously brick g1, so one 3 phones, all the same battery life but then I use it quite heavily, always browsing on the web since my computer burned out
http://forum.xda-developers.com/showthread.php?t=555048
try that? 3rd gen battery could help..
Thanks for the suggestions, but it's not a wifi/3g/brightness etc problem - I've had a G1 for six months, I know exactly how much power should be consumed. It's also not the battery; I have two stock batteries and a brand new 2400mAh battery, which for the first few charges lasted about 2 - 2.5 days and was brilliant (as it should be), but now doesn't last all that long.
I may have made the situation slightly better however - I did a Nandroid backup, wiped to factory (well, Cyanogen 4.0.4 anyway) and booted into that. I then restored the backup and when I plugged back in to the charger, the meter was at 85%, and seemed to take a normal amount of time to charge (and not jump to 100%). It remains to be seen if the problem is solved, I've yet to have the battery drain (this is a good sign though) an plug in the charger to see if it will jump from 0 to 25 or not.
I'll re-post when I know.
run the battery down until the phone shuts off without plugging it in.
charge the battery while the phone is off over night
do this 3-5 times and see if you get any improvement.
also remember some of the cheap 2400 batts from ebay and such claim 2400 but that is from 3.5V to 3.0V. The G1 considers 3.2V to be dead so you only get from 3.5V to 3.2V which sucks.
I'm with gridlock on this one. My batteries suck. It always needs a mid day charge. And to the poster that said to reflash a rom, that is bad advice. There is known issues with getting poor performance out of these batteries. I have 2 and both do the same. Got the second one from complaining to t-mo about how bad it sucks.
Reflashing seems to have worked...the 2400mAh battery seems a lot better now, it lasted nearly two days (it runs at 3.7v, according to my battery diagnostic), I've only just recharged it last night. When I plug it in, it charges normally and linearly now, instead of jumping straight to 25%.
So my advice, if anyone is having similar problems to me, would be to try a reflash.
Thanks for your help everyone.
Anyone else notice this?? I've run both the first and the second 2.2 leaked Rom, and both exhibit this same issue. Okay first a little info: stock battery, stock HTC wall charger and stock use cable. I don't charge off a use port on a comp, always the wall charger.
Now, on stock 2.1, I could run the battery all the way down, connect the charger, and be back to full charge in max 1.5 hours. On 2.2, it takes more than twice that long. So I went thru the whole downgrade process (pain!) to get back to stock 2.1, ran that for a day and confirmed, charging on the wall charger gets about 1% a minute. Went back to 2.0 radio and second leaked 2.2 ota, and yeah, back to taking 2-3 mins to get a percent, about 3.5-4 hours to full charge.
So..... what gives? Anyone else noticing this? Can it be fixed via patch or something? Is it the radio, the new kernel, what?
its probably the new radio. i dont know how the radio directly affects battery life tho. it is not the kernel, because i am running cm6 and the problems have persisted on cm6 too. i have been experienceing these problems too

The radio could be the #2 drain on a battery (short of 100% on screen) ... if the radio is not getting the signal it wants, it hunts and hunts, and 1x draws incredible power from the battery vs 3G.
The buggy radio and buggy beta could easily be causing you trouble in your area, if they just don't play right with the signal you are getting. Hopefully when the non-beta radio comes out, things will change.
Mind you, my battery life seems fine, no worse than stock anyways. It's just the charging time that has gotten dramatically worse.
Same..there's no reason my phone should be charging for close to 4 to 5 hours I don't know what's up with that

I may be all wet...but there is a battery file in your phone that I think gets wiped when you install a new ROM.
I do all of my charging at night, so I don't know how long it takes after wiping and installing ROMs. I do remember it taking about three hours to charge the battery the very first time I plugged it in.

Doesn't explain why after I wiped and went back to 100% stock my charge time went back to taking no more than 90 mins...
Nah I flashed roms all the time on my Droid never took this long to charge. Even on my inc cyanogen 6 never took that long its definitely something about 2.2 roms or sky raider.
I have this problem on mine and made a thread on androidforums. After watching a few things I came to the conclusion its the cpu speed. It never throttles down below about 500-600 mhz. Open setCPU and don't touch anything. You'll see it won't drop to the 200s like its supposed to.
Someone came up with a work around by using setcpu. Create a profile for when the screen is off so that the max is 245 mhz. You'll find that your charge times will be a lot better.
Even though this works I would like to know why the phone is not throttling down at idle like its supposed to. Someone with more knowledge might have the answer.
I had noticed that and posted a thread about it awhile back. I have a hard time believing that is the sole reason for tripping charge times though

all the explanations posted so far would be a cause of battery DRAIN issues, which most people claim to see better overall battery life since jumping on 2.2 (myself included). none of these could explain why charge times would take twice as long. i myself have had better battery life on 2.2, but charge times are definitely in the 3-4 hour range as opposed to the 1.5 hours it was before. BUT, one theory is htc might have lowered the charge input from what it was before, meaning a slower charge time but preserving battery health and possibly increasing battery life. just a guess, chemistry majors correct me if im wrong lol.

If the phone isnt underclocking even when the screen is off, it would be using more power even while charging, which would explain the long charge times.
Proof of concept would be, if you try and charge while using bluetooth and gps in the car you may not lose charge, but it will not charge as quickly as if you are not using those things.
if the CPU use is high then the battery would not charge as quickly.
I'm still not so certain that the setcpu profle has solved my problem, still havent been conscious of it enough to be sure.

Common sense would tell you that if something is draining the battery, charge times would be higher...
Gbenj. Its definitely not a full fix for it since it requires the screen to be off but it has definitely cut down on my charge times. Its still no where near what it was for 2.1 but atleast I dont have to wait 4 hours for 10%.

All understood, BUT, yesterday when using gps nav for a few hours and on the car charger, i was actually still LOSING battery. nothing else was on (bluetooth or wifi) no calls, no texts or anything. 2.1, i still gained charge while using gps on the car charger as well as having an overclocked kernel. so its definitely not a cpu issue considering peak processor speed has not been tampered with.
Just a thought but perhaps the FROYO Rom that you flashed has a fix in it for the problem with charging. In otherwords perhaps it is actually charging the whole battery. I haven't paid any attention to mine as to whether it is taking longer. I usually just charge while I sleep and then while I am in the car and sometimes at my desk if I plan to plug in for something I will just leave it plugged so I get more use of higher drain features when I go home. I noticed though that if you bump charge as recommended, (pre-update) I only did it once and saw little to no improvement, it took for ever. After I charged it to green, I turned it off and charged it to green, unplugged it plugged it back charged to green, and repeated until it was green when I first plugged in. Now it seems to me that the problem is a software/system issue so it would be plausible that a software solution could be developed. I haven't tried since I updated and the ROM I am currently using gives me the same battery life I had before but now I can leave GPS on all the time something I couldn't even think about with Stock everything.
So I may be wrong but it may be that it is taking longer to charge because it is actually charging the chunk of battery that it hadn't been charging before. Just a thought and since I am pretty sure I don't have the same ROM you have I won't venture to test and post results but perhaps you could.

bump charging is still required by anyone on 2.2 so its not charging any more of the battery than what it used to, just a lot slower.
Agreed, it doesn't make bump charging any less required for "full" charge, also, this theory would mean we'd be getting significantly better battery life.... I most definitely was not.
It's possible they reduced the charger output to the battery to increase battery life/reduce heat while charging.

if by battery life you mean overall battery health over time then yes, that is what i believe as well. also, these leaked froyo roms are all developmental, not final releases. im guessing that they may have tried a fix for battery issues but it didnt work out right in these roms so im hoping in the final release it will be truly fixed.
has anyone noticed that the battery stops charging after a while? it almost seems like the system is stopping the charge because its running for so long. anyone seen anything like this?
After much googling this is the way that seems to be best when recalibrating battery. I just see so many people with poor battery life and it's likely because you've flashed new kernels and roms 50 times a week =p
Minor update! I recalibrate my phone today and realized something, this is reflected in a few new steps.
Step 1: Charge phone to 100%
Step 2: Wipe battery stats and shut phone off.
Step 3: UNPLUG PHONE and power on
Step 4: Leave phone on until it it shuts itself off. Do not plug it in.
Step 5: Turn phone back on, still unplugged. If it can't turn on that's fine. If it can turn on let it fully drain again.
Step 6: LEAVE PHONE OFF. Plug the phone in and let it FULLY charge without interruption. I let my phone hit the green light and then wait an hour before step 7. Some people suggest waiting 3 hours, some people suggest longer.
Step 7: After it's hit green and you've waiting a while unplug your phone. Do not turn it on. Wait a minute and then plug it back in. If the light stays amber for more than a few seconds (like 10 tops) leave it charging again until it's green.
Step 8: Repeat step 7 until the light turns green very soon after you plug it back in.
Step 9: Unplug and turn your phone on. Enjoy your (hopefully) extended battery.
I also suggest using "Juiceplotter" widget. It "records" your phones battery usage and uses it to predict future battery life. It won't work perfectly for the first day or so but after it gets used to your habits it's very good at predicting.

Thanks dude, I guess this will work with calibrating a new battery too? Just got the 3500 battery and was wondering exactly how to calibrate it for the first time...
Yes and I suggest recalibrating if you
a) Have a new battery of any kind
b) Have a new eris but the same battery
c) Flash a new kernel
d) Have been flashing many new roms
I find it' s a good habit to only flash roms when you're battery is at 100% to prevent your phone from getting too confused.
I read that after 5-6 full discharges of the Seidio 3500 battery that your battery life will improve... But I also heard that full discharging and then charging isn't as great for your battery... so what should I exactly do? I've already discharged and fully charged it once.
HM, you should also start a thread about "Tweaks I've found useful, and how to do them" and share your findings with everyone. I think that would be very helpful to noobs and the less-than-technical types that would like to get more out of their Eris'.
I know that's alot of work, but I'm sure lots of people would help answer questions when you're not available.
And you can add stuff as you go, wip type page Just a thought, cheers!
I'll consider that, I just feel like I don't have all that much to contribute that others haven't already lol but we'll see.

Your eris's battery will never discharge completely, it turns itself off WELL before that point. You don't have to worry about hurting your battery in this day and age, maybe 10 years ago.
If you've discharged and fully charged once it might be recalibrated. Are you still having battery problems?

This is one way to calibrate it but if you've been flashing roms/kernels just going to "100%" isn't enough because your phone doesn't know what 100% is. I'm sure that way works well when there isn't a huge problem but for some people their batteries are way out of whack.
How about having 2 battery?
Right now i have 2 battery and switch one of them when other runout of power.
Should i calibrate both of them?
Is my way to switch battery is wise?
Thx
Sent from my using XDA APPS
Don't switch between a 30% battery and a 100% battery, try to keep them around the same percentage. I can't say for sure because I don't know how the phone deals with that..
I tried this method yesterday (charged to 100%) , then last night and this morning drained the battery till dead and then charged to 1 hour after LED turned green. After I re-started my phone I was getting 1 % battery drop almost every 30 seconds, or every time I touched the phone it would drop a percentage point. :yikes:
So, I incorporated the "other" method mentioned here and turned my phone off (at 90%), plugged the charger back in and let it charge about 30 minutes after the LED turned green. I then booted the phone into recovery (while still plugged into the charger) and wiped battery stats, rebooted, and then unplugged the charger.
After this, I left it on for about 10 minutes with 3G and Sync active and only got 1% drop.
Kinda thinking this may be the ticket, for my phone at least.
Thanks for posting this up, I'll keep an eye on things and see if I can notice a difference. I was getting pretty decent battery life prior to this, but I agree that things need to be cleaned out sometimes after all these flashes.
I'm going to wipe GPS this afternoon and re-set it. Too much fun!
Yeah I did this method, wiped stats at 100% let die completely, charged all night turned it on and only had ninety percent and falling without using it.

Yes, my battery life is pretty ridiculous. I haven't dropped down to 50% since I did this.
I've gotten to 66% while on a lengthy phone conversation with my Gameboy emulator in the background, and then some gameboy (fully overclocked) for another hour at least.
I suggest using "JuicePlotter" widget for monitoring battery. After a few days it becomes very accurate.
I'll check out juice.
No setcpu. Just stock 710Mhz. Conap's CFS kernel is light on the battery.
Also, I play around with the auto bright settings to use the minimal needed for various lighting environments.

I see a lot of people not using SetCPU anymore. I like using it to underclock while the phone is not being used. If the kernel is 710Mhz stock now, would I just set SetCPU to 528Mhz for normal use or would that override the kernel?
I don't know if it's my imagination, but since the 2.4.6 update, my battery life has dropped a bit. By the time I get into my office from my morning commute, I'm anywhere in the 65-70% battery life after unplugging from a full charge. I haven't done anything new. I always unplug around 8:30 am when I head out, I do some light chatting with gf, browse some sites, check facebook (usually very briefly), and maybe sometimes do a little reading on my device. By the time I get into the office around 9:30 or 10 AM, I'm usually around the 80-85% area with battery.
Lately, doing the same thing, I'm seeing the aforementioned 65-70%.
Is anyone else experiencing decreased battery life since 2.3.6?
I'm on a Tmobile Nexus S, running stock 2.3.6 (no custom ROMs).
2.4.6 ? .... maybe 2.3.6 ... and yes, I also noticed a slight increase in power consuption after the upgrade. The stand-by is still great .. about 0.8 - 1% per hour.
Sorry, yes I meant 2.3.6.
Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?
I used to get home with about 40-50% after a whole "normal day" (unplugged at 8AM, and getting back home at ~8PM) .. now (with the same average usage) I'm getting home with ~30-40% ... that why I said "slight increase" ...
Not your imagination, I too have noticed this. I hope the next update, will fix this - as I used to get pretty good battery life (even with over 250 apps).
When I recently updated to the 2.3.6, it caused a bug of continuous reboot (every 1-3 minutes), so I had to do a hard reset - now it works fine, but I only have added back about 15 apps - and the battery life sux!
Downgrade OS' it will be ok.
This is so weird. Why is the battery life worse?

Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?

You want bad battery life? Try an Evo 4g with a Sense rom. I averaged about 6hrs using a 1500mAh battery, in stock form.
The nexus is pretty light on power consumption, if you ask me. I average 15hrs on the stock 2.3.7 rom/kernel combo, with stock battery.

I'm on 2.3.6 and need to charge every two days. I text a lot and do light gaming. I'm typing this from my phone. Maybe you could drain the battery and wipe battery stats? I'm not even at 50% yet and I charged yesterday.

I also noticed that the battery last less time
I've been waiting to see if anybody else reporting this issue
i noticed a decent increase in battery life going to 2.3.7 and thought that previously the battery life had been fairly poor :\
I am non rooted, and get around 20 hrs on light to moderate use. Again. Stock, non rooted.
How do I recalibrate my battery? I wonder if it could be that...
There are many was to recalibrate. Some involve wiping batt stats, some plugging and unplugging phone several times after charge.
I have always found that using the battery almost all the way down, but not past 5%, and then full recharge conditions it very well.
Oh I've been here to solve the problem
"Why last 2 weeks my Nexus s drain battery so fast ? or I have to calibrate it"
Thank for your notice about update OS to 2.3.6.
I think that's a root cause for me too.
1. Could I rollback to 2.3.4 ,how?
2. Does battery calibration is useful for this case , how?( someone suggest to calibrate when flashing new rom )
Thank you very much..
i want to know who have some methods to do with this stuff

Whenever switching roms, kernels, or batteries, i always perform the following :
1. Charge to a true 100% (Battery Monitor Widget will register +0 to +2 mA)
2. Wipe battery stats using recovery (Amon RA has this option for the Evo, not sure about cwm), Battery Monitor Widget, or a dedicated app.
3. Discharge battery to 0% with normal usage. When the phone shuts down, I pull and re-install the battery and power back up (it will shutdown again very quickly).
4. Recharge battery and be on my merry way.

I found one workaround solution for this issue on
ww.google.com/support/forum/p/Google+Mobile/thread?tid=1684c50cea15282a&hl=en&fid=1684c50cea15282a0004af022e5ed212
Sproogle77 's solution
Problem solved. Using the OS Monitor app, I found that the main culprit was Google Services - the Contacts sync specifically. Even though I had this disabled (only Gmail was being allowed to sync) it was constantly working, apparently trying to fix a location. The message log showed that it was generating continuous debug messages, all about locations - around 10 of these every second.
I have solved the problem by disabling 'Use wireless networks' under the Locations & Security settings.'Use GPS satellites' is still running. This immediately dropped my CPU usage - which had been running around 30 to 40% even when otherwise idle, to around 10%. Google contacts sync is now using 0% of the CPU. The difference in battery life was pretty much immediate and is now back to what it was before - the change in the slope on the battery usage graph is remarkable!
This doesn't really seem like a solution to me, and I don't know whether other aspects of my functionality are being affected, but at least my phone is properly useable again.
I'm testing for 1 day and I think that's working for me.

This is so weird. Why is the battery life worse?

One reason is that the new version of the stock kernel removed a speed stepping, so it'll power to higher levels faster, thus using more battery.

That actually isn't the problem. I'm using netarchy's kernel and still get this problem.
My battery life dropped from 16 hours --> 6 hours. the slope on my battery usage life is horrible the system is also awake almost constantly even when I'm not touching it / getting no messages.
I will try the fix suggested on the google support forum and see if that does the trick. sloppy update.
So, I decided to finally root my SGSII..and everything went smoothly..n I was happy knowing that now I could do many things with my phone...it eas working normally with no issues but, after some weeks, my battery life was just awful..it wouldn't even last 15 hours..n I was worried..started searching for solutions, but didn't find them..n then Istarted getting used to to this poor battery life..
Now the interesting story..
One day,I went to fetch my SGSII n I was expecting it to be off, with no battery, n thats what happened,n I didn't even bother charging it..it remained fully discharged for, I think more than 24 h, then the next day, I needed it so, I fullY charged it, turned my phone on, n started using it..
by night I was expecting my phone to be fully discharged..BUT, it wasn't the case this time around as my phone's battery started working normally..just as it before...
Try it...at least it is not risky

Sorry, I saw empty post. My response is now useless.
But... how will I survive an entire 24 hours without my beloved SII?
Most people just learn why the battery drain occurred. And fix that.
Basically this works with Battery Cycles - discharging your phone from 100 to 0 and charging it all the way up again without interruption; has proved to be a handy way to keep a healthy battery life just as my SII has did.
do u huys have experience with battery caloboration apps?

They don't work. Ignore them. Simply charge your phone to 100% from flat and its battery will be calibrated.
Also disable chatting programs like msn messenger, whatsapp, kaokaotalk, facebook will save your battery. Those apps keep updating and sync at background.

Never had a issue with Whatsapp or Facebook when set to PUSH mode rather than scheduled updates.
Epic first post. I found that if I don't use my phone, the battery lasts longer than if I do use it. Hope others share their tips too, as there's a shortage of battery threads.
Its not that important that you wait 24 hours.
The most important thing is that you let your phone discharge until it has very few percents left or even shuts down by itself.
If you then fully charge it while it is shut down you should get much better battery results with your next circle :good:
battery life
my battery life is awsome!! after 22 hours of a very little bit of use i had 76 % battery life left !
siyah kernel 3.5.2
rootbox JB 2.0
i had almost 2 day with rr 2.6.1 and cm9 . i think that this is the perferct combination for baterry.
Leaving empty (0%) lithium-based battery without charging for more than 2 hours is stupid - lithium batteries are degrading very fast in empty state.
// tip for notebooks and phones
i getting also faced this problem too. Empty that battery and charge handphone on offline to make it fully chargging.

Don't worry about the battery life. Just use the phone through the day as God intended, dock it at home or in the office and charge it over night.
Job done.
