I've installed the Yelp, Movies, and Amazon app, nothing else, and I'm losing around 15% an hour with light/normal usage.
I've let the battery run down to 0 and recharged completely, I've turned off gps and wifi, and still get really bad life. I live in the Bay Area and get a solid signal all of the time. There's really no excuse for it.
Please don't tell me to flash to a rom, because that's obviously not fixing the issue. Light browsing and the occasional Google Maps has my phone at <20% by the afternoon.
Battery stats just show android system and screen brightness taking up power. What's the deal?
I also constantly have at least 255 / 328mb in use even with all applications closed.

The mb usage is normal i noticed this on stock because of Verizon apps that run in background. As far as not using the phone and only getting 6 good hours of use. i would take to the store and ask if they could change out the battery. Hope this helps.
+1 for that, sounds like you have a defective battery.

Thats about how long my battery gets me.
And if I forget to power down my phone at night, or put it on a charger it is dead by morning no matter how much of a charge it has before I go to bed.
I have an extended battery starring me in the face and can't use it yet since I couldn't find a door and had to have one shipped from Samsung.
Hopefully the extended battery cures my issues.

I am curious as to what you guys are running. And if you go to bed with your phone on , and its dead by morning I can PROMISE you there is either something going on with your phone, or you are doing something wrong (i.e. you have your phone set to never sleep, your screen is set to maximum brightness, your are leaving your phone in desk cradle mode, etc etc etc.) But it's not the phone. May be a bad battery, but without being at your house and seeing what you are doing, I have no intelligent answer for you.

charge phone to 100%, boot into clockwork recovery and wipe your battery stats, then use the phone until you completely drain your battery until it shuts off. Then charge back up completely. This will calibrate your battery. try running a customer rom such as gummy charged or humble to see if you get bettery battery life... thousands of users have reported great battery life with both
I had same crummy battery life. I followed the calibration instructions and i went from about 5-6 hr batt life to ( right now im at almost 11hrs with 66% battery left on wifi with moderate use). Ill test tomorrow on 4g only and see how it does. I would get like 4-5 hrs before.

I am running the latest humble and my battery drops really fast. If I go into task manager and clear my RAM, I get better battery. I calibrated per the instructions as well about a week ago or so and saw no improvement. Please note that I have not been scientific about it at all.
Stopping Data obv helps a million and clearing RAM seems to help as well.
EDIT: I am recalibrating in case it was not done properly before. Hopefully it will help. I am hopeful!
I charged my battery to full, booted into clockwork recovery and wiped my battery stats.
When I rebooted my phone it shows a 73% charge?

If you are on humble 1.x then that means your battery stats were way off. Basically your battery still needs 23% more charge before its full... thus better battery life... because you had a miscalibrated battery, your phone is erroneously reporting a full charge... charge it back to 100% then discharge fully then charge all the back up

I'm on Gummy Charge GRE, but I assume the same reason?
I exchanged my battery at verizon. So far it seems better. Ive let it drain and am recharging now. I will also try uninstalling g+ if the new batt hasnt solved the problem. I will post back with an update.

I switched out my battery 2 days ago, and I'm still getting under 6 hours with moderate use.
Has anyone had luck with ROMs drastically improving battery life? I can't imagine it being the phone itself, but I might try exchanging it too.
EDIT: it seems like the new battery charges a bit faster. My old battery would take around a minute for one percentage gain. Can anyone comment on their charge times?
I read a lot of thread about battery calibration so I want to know if someone try this on XT720 and if it's really usefull and not dangerous for the phone.
Thank you
It is useful and not dangerous at all. Your battery has, if stock that came with phone, a full charge of 4.2v.
So let's say that you have been conservatively using you phone most of the day and are at 70%. You decide to flash the Hellmonger edition or CM6 but you make a nandroid backup first. You flash them and it goes horribly wrong and your phone power dwindles down to 30% and you freakout and charge it back up.
When it is charging, you decide to hold off on flashing for a bit and want to go back to your "home" ROM, whatever that may be. You let your phone charge up to 100% and re-flash your back up. Once it reboots and settles down, you happen to notice that just 5 mins ago you were at 100%, but now after flashing your backup, your battery shows 70%.
30% drop in 5 mins is rediculous. Yes it is, bit it didn't really drop 30% in 5 mins because when you backed up your original ROM, you also backed up your data/system/batterystats.bin that was calibrated to 70%.
If you use Battery Calibrator and charge it up fully, run app, hit it and then unplug, it deletes the data/system/batterystats.bin and in a few seconds (5 ithink) it creates a new one with you proper charge and voltz.
So if you flash a lot, this is good for you. Or you can delete the batterystats.bin manually if you want, but there's an app for that.

So, if I understand, it's not so usefull because after I lose my 30%, if I charge and I have 100% it's really 100% not 70% right ?
I would say that it is always best to start from a clean slate. It deletes that batstat file and starts anew. Can't hurt, but if you are flashing ROMs every 3rd day like most of us, it does come in handy.
For the moral of the stroy, it will not damage your phone. Just a one click app that you can do manually with Root Explorer if you wanted to.

Its recommended that the battery drain fully, and then be recharged without interruption. I guess thats to give android a full scale from full to empty, to help better report battery stats and consumption.
However for me full drain means 10-15%, its hurts the battery to be drained till the phone powers off.

I used to drain it fully till my phone turned off before calibration but I read a very detailed article about how draining the battery completely can hurt it. So I choose to drain it till 5-10% which is good enough
How come sometimes when the battery is full it shows 4200mah like it should but sometimes it shows less like around 4165mah in the battery calibration app? At 4165, I still left it there to charge to see if it would increase or not but it didn't...
Sent from my MilestoneXT720 using XDA App
I know that the last little bit of charge just trickles in and takes a long time. If mine is at somewhere between 4150 and 4200, i call it good and go from there. If it was showing at say 4095 and 100%, then there might be something wrong with either the data or the battery. If you are sitting at 4165, then it is charged for the most part.
The app and what it does is more for when you are flashing a ROM and have around 60% and then once booted up fully, you charge it up to 100%. Decided you don't like your ROM and go back to your original ROM via backup, it will show 60% instead of the 100 or 90% you had before you went back to back up b/c you backed up the batstat bin when you nandroided your original ROM.
How about this:
ROM: Epicsteelblue 70% (and you made a backup) Then went to CM6, charged and hit calibrate battery at 100%. Used CM6 for a few hours and decided it wasn't your bag. Your batter is at 50%. You flash back to your Epicbluesteel ROM and you know for a fact you had 50% before you flashed back, but now once totally booted, you are showing 70%. This is why you use the battery calibrator after you flash a ROM. Gotta create a new batstat bin for you "fresh" ROM (even though it is a backup).
Hope this helps explain better.

That happens sometimes to me aswell. The battery calibration app shows the battery full at 4165 or somewhere in that range. What I do with that is bump charge it. So if battery calibration shows 4165, i just calibrate it and turn the phone off while it is connected to the charger. When it turns off the charging screen appears and shows 100%, i leave it there for an hour or two. Then remove and turn the phone on. If you go into the battery information itll show the charge to be 4200 or close to that. Hope that was helpful you can try it next time.
EDIT: The reason I turn the phone off and let is charge is that when it reboots after fully charging to 4200 it can create a fresh battery stats. Remember battery stats are only rebuilt upon boot. If you calibrate your battery and then dont reboot its useless. To test calibrate it, and then use it for awhile and then try to recalibrate it the app will indicate that there are no battery stats avaible to delete. This is because the ROM has not made any new battery stats and will only make them on boot.
hey guys has anyone tried this method (http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10) of calibrating battery? it seems the dev says that if u use his method, you can calibrate without downtime!!
wow this is damn cool. but its kinda complicated. the old way feels better for me i think...
Battery Updates
The battery updates every 10%, is there any way to make it update more precisely, like every 5%?
I've never been able to get anything better that 10% battery increments
Okay thanks maybe in a future rom this would be nice.
Hi
Is their a way to change from 10% to 1% increameants.

It is the property of all rechargetable battery, 4.2V can only see at the moment charging progress just finished. when the power management IC pull of charge current, battery's voltage will drop a litte in a very short time, like you said, 4.165V for example. And, because of your charger is connected, battery will not drain, It won't be another charging progress witch you are expecting.
I know I'm digging up an old thread here, so sorry for that. I've recently tried a few other ROMs, but since have come back to CM6.3.7. I always do the battery calibration thing when I flash ROMs and each time I've tried it lately, it gives me odd information in the Battery Usage screen. I charged my phone to 100% yesterday before leaving work and when I got to work today, it showed 70%, which seemed normal, but the Battery Usage screen showed "1h 24m since last unplugged" and I know I hadn't plugged it into the wall or USB for about 12 hours. I did restart once....could that be the reason why the time since last unplugged is incorrect?
Has anyone realized this or is it just me, every sense 3.5 that I've tried the battery indicator is incorrect.
For example, I just had 41% battery life before resetting my phone and now I have only 4%. Is it not charging the battery correctly? I also turn the phone off after it says 100% and then charge until the green led comes on but still it is either draining too fast and phone doesn't detect it until a reset or the battery isn't be charged completely because the rom thinks it's 100. I have caliibrated and erased the batterystats.bin file so many times and it's still the same. any insight on this? I have a brand new battery from htc as well.
Same problem
Constantly "calibrating" or deleting the battery stats is the exact reason this happens. You dont have to do that, regardless of what people say.
This will happen until the battery has been charged/discharged a few times and will slowly stop happening.
No issue here, got my new anker battery.. Flashed BP 2.1.5 and since then, my battery has been normal and amazing!

This. When I flash ROMs I don't really do anything in relation to the battery. I just use my phone like normal. The first day or two you might get a little more drain than usual, but after that it will be completely normal and you don't have to do anything like wipe battery stats or calibrate or run it down to 5% and charge it all the way up or whatever.
Yes, constantly resetting battery stats is bad. Should only occur right after flashing the new ROM. Ideally you'll have charged your phone to 100%, flashed the new ROM, and immediately putting it through 5 discharge/charge cycles.
My battery life was horrendous when I didn't properly calibrate the battery. Going through the process now and its lasting a significantly longer time compared to not going through the process. I'm talking about getting like 6 hours of light usage compared to like 15.
Or it could be just ARHD. I really didn't like that ROM. Anyways, I'm running Bulletproof 2.1.5 with 3.5 Sense on an Anker battery and its doing great.

This is with a new battery, new rom, totally wiped device, I even used the ruu to get me back to the stock rom.
Anyone have any idea what's the problem? The battery life is ****, and doesn't seem to get any better with calibration.

This is your culprit. Let it bed in a few days, and performance should stabilize.
Go through 5 full charges/discharges, uninterrupted. Yes, it's a pain in the ass, but you signed up for it when you flashed a new ROM.
Everytime you wipe your battery stats, you have to go through the 5 cycle process again. Uninterrupted.
EDIT: Had a lil too much rum and misspelled a few words. I even misspelled mispelled
Alright dude, I'm going to take you up on your word, I'll give you another update within 5 days.
This is a problem with all Sensation ROMs, even with S-On and Stock ROMs. I get a problem like this one too. If I have 60% left, and I restart the phone, it goes up to 69% and I don't know why. Also very slow charging from the original wall charger, but if I reboot when it's charging at 70-75%, when it finally boots, it says 100% charge. This must be some bug from HTC or something. :S

It's not a hardware fault...it's not a battery fault...it *may* be a ROM/kernel issue...but I suggest you give your battery a few discharge/charge cycles and you'll see it should go back to normal.
I posted this in another forum and the response I got was somewhat weak. Instead of re typing everything I will cut and paste my posts and hopefully you guys can guide me in the right direction!
Here was post 1 -->
I just bought a Rooted Nexus S from ebay. It is running this ROM Nexus S ICS 4.0.4 stock OTA ROM (IMM76D)
Now, I know nothing about android, I'm coming off a series of old turd phones because i'm always breaking them. I'll probably break this one too, but hopefully not for a while.
When I got the phone I put the battery in and turned it on, then charged it overnight. It will only charge to 54% and stay there. I talked to the seller he said it charged normally for him. He said he did a complete wipe and USB wipe before he shipped it.
The battery seems to drain normally (I guess, I have nothing to really compare it to) from 54% but it would be nice to have it charge to the 90% -ish range haha. I allowed the battery to drain to 40% and put it back on charge, it been on charge for almost an hour and will only charge to 41%? Do you guys have any ideas what I can do to fix this? Is this a sign it needs a new battery, or a software glitch? The seller said the battery shouldn't need replacing.
Also in the battery app under setting, Android System is using 28% is that a lot?
My last question is an important one to me haha. Is there anyway to convert the querty keyboard to a T9? I 've gotten used to texting with one hand and T9 makes it so much easier to do so.
Thanks everybody!
Someone recommended I try the battery calibration app So I did!
Post 2
Ok, I ran the Battery Calibration app. I let my phone charge for hours. It would only charge up to 38% this time. However, the percentage was 38% but it was charged to 3810 mV (and would not charge past this point). And full charge is approximately 4200 mV according to the Battery Calibration app. So I assumed that 3810 mV was my current battery's max charge (keep in mind it is a couple months old) and set battery calibration at that point.
This is from the app description --> It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
So thats what I'll do. I should mention that even though I ran the battery calibration, the battery percentage has been draining from 38%. In other words, my phone now reads 26% battery charge, but is at 3758 mV.
I'm thinking that when I go to charge it after fully draining the battery, it will hopefully charge close to 100%. It seems as though the percentage is the only thing that is off. Because the mV reading seems accurate.
Here is a screenshot, what do you guys think?
This site won't let me post the screen shot until 8 posts, but I will do that once I get there!
Post # 3
The app says to let the phone fully discharge after calibration. I am now at 15%, but mV is at 3658. Should I recharge when the percentage has dropped lower, or when the mV reaches a low point? Are these phones really this finicky. I'm starting to miss my old 2007 flip phone haha
It's now at 14% and now asking for me to plug it in to charge lol but mV is still way high (3655)
Post #4
update, charge % reached 0 and the phone shut down. Now charging, Current charge is at 0%, 3595 mV. No one has any idea whats up?
Shouldn't mV be near 0 when charge is at 0%, and be near 4000mV when charge is near 100%?
hopefully you guys can help me fix this issue. Otherwise it'll have to go back to 'ol reliable, the 2007, multiple cracked screen, nokia slider lol It's not pretty, but it works!
There is a built in safety feature in our batteries to prevent deep discharges. IIRC, the safe cutoff point is around maybe 34xx mV. I could be off, but its to prevent damage to the battery. Here's more on them
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
As for voltages, a full battery should be around 4100mV. Mine tops out around 4196. I'm not too familiar with all of it though. Most of the stuff I learn is through observation and links others provide.
Thanks for the reply! So are you saying that when the voltage is around 34xx the battery charge % should be close to or around 0%. And when the voltage is near the 4000mV range the charge %tage should be approximately 9x%
Do I have the right idea here?
Its hard to say while its charging. My phone is at 4000mv around 70% so I don't really know exactly how it works. But a full battery should read around the voltages I posted. There's people on here who know more about it, so hopefully they'll chime in.
But yes. When its close to zero, it should be around that range. It will differ from battery to battery.
Ah k thanks! My original problem was that the phone would only charge to 54% and would not go past that point. I'm waiting to see if it will get into the 90 ish % range after running the battery calibration now.
The app itself doesn't actually do anything. The stats will get reset once the charge reaches 90% My girlfriend's phone was the same way. It wouldn't charge past 75%. I let the phone run dead and charged it while it was off and it fixed the problem. If it doesn't go to 90%, try charging while off and just letting it run until it gives the warning to charge, turn it off and let it charge overnight .
Ok. Well I let the phone run dead earlier today as I mentioned in one of the above posts. But I didn't charge it with the phone off. I put it on charge with the phone on, and now it won't charge past 11%
It just seems to be getting worse and worse? It's been going between 10% and 11% and has been at 11% for about 2 hours now. Maybe this time I will drain it again and try charging it with the phone off like you suggested.
This is slightly annoying
All else fails grab another battery. They're dirt cheap on eBay. Just get one from a reputable seller
Ok, so I let the battery drain. then fully charged it with the phone off. When I turned it on, it had 47% charge.
The guy I bought it from said that before I buy a battery I should download an app called rom manager and download a new rom. he thinks its a software bug because he had no problems with the battery when he was running cyanogen mod 9 on it.
I wouldn't mind giving trying this, except I don't even know what a rom is. Is it operating system? I like the way the phone works now, If only I could get it to charge fully.
Thoughts?
Ok, I just did a bunch of reading and downloaded ROM manager premium. Hopefully I get this figured out. Owning one of these phones is a lot of work
lts pretty much a pocket computer. Coming from an older type of phone, a lot of things are going to be different. Gotta start somewhere. Reading up on it and toying around with the phone will help in the long run. Trust me.

Haha, pretty much. I'm slowly starting to learn more. I didn't think there was this much of a learning curve, thats what took me by surprise thats all. I'm a fast learner so I'm not too worried. I didn't have time to play around on it tonight, maybe on the weekend. I found out I could use it without the sim card which is awesome! Because now I can use old faithful while I learn more about android.
Thanks for the help so far though, I'm sure I'll have more questions soon haha
Haha. Yep. You can have tons of fun just using it over wifi!
Do keep in mind, fully dishcharging a lithium ion (li-ion) battery deteriorates the battery even more. We only discharge because older phones use nickel cadmium batteries which need more maintenance to get to their maximum life span and use.
Off topic though.
Battery calibration just wipes your battery stats. You can do this by going into any recovery program eg clockworkmod receovery or team win recovery project. You can wipe the battery stats yourself. If that still doesnt work. Try doing a clean install of your custom rom or kernel. If your not on a custom rom or kernel. Nor your rooted. Try formating the SD card in the Nexus S (or fully wiping the sd card). Than do a factory reset.
Ok, so I finally had some time to learn to flash etc. After backing up, I downloaded and flashed the same rom from SD, I cleared davlik cache and also selected the wipe data and cache option from ROM Manager (I assume that this is what is called a clean install?)
This is the ROM I am using http://forum.xda-developers.com/showthread.php?t=1653713 Slightly customized stock ROM, rooted.
After start up I waited a while and then plugged it into the charger, it only charges to 54% still. Sometimes it creeps up. One thing I noticed is that if I use the phone while it is charging, it actually drains the battery. So it will go from 54% to 52% and slowly drain. Is this an indication of a pooched battery?
Any suggestions? I will order a battery. Where do you guys order your batterries, I read that the oem samsung 1500 is reliable.
Hi everyone,
I've had my Sensation for about 14 months now and for the past month I've been having battery issues. Primarily, it's very quick to lose charge and will lose charge even while charging from the wall. First I bought a replacement battery but was still having the same issues. I've started using Better Battery Stats and Battery Monitor Widget but I don't have anything out of the ordinary running. In fact, not a lot is running at all. BMW has allowed me to see how the charging is going though which has been nice. During this period I have used Elegancia, Bruce's CM10, and am currently on ParanoidAndroid. All experienced the same issues.
Last night, for example, I put the phone on the charger at 16 percent. It charged up to 22 and then started the downward slide to death and I ended up waking up 35 minutes late.
Where do I go from here so I don't have to constantly be paranoid about my battery levels?
Sounds like you might need another battery. In better battery starts did you notice any unusual wake locks? This could drain a battery. But since it looses charge even when charging I'd think it was the battery. I personally was experiencing some battery issues myself finally I broke down and got a mugen 3800mah battery from mugen. It was expensive but really worth it for Me.with really heavy and constant use I get 20 hours out of my battery, with normal use I get two days. I'm also running paranoid Android rom. For me the big battery solved my issues. Only one draw back, it does make your phone thicker. New back included with battery. This didn't bother me much because of the excellent battery life I receive. Now I finally don't. Worry about battery. However it's expensive at about 95 dollars. But I was so fed up with poor battery life it was worth it for me. You have to be careful when buying inexpensive batteries because there are a lot of fakes going around. And the mah is not really what it says it is on the packages. You can test the battery and make sure it is what it's advertised to be. If you don't want to go with that large of a battery you can also try anker extended battery. It's a lot less expensive and is a good battery. I personally needed more juice so I went with the big battery. I know you said you replaced the battery but sometimes the bargain batteries go bad quickly. It makes me suspicious of the battery because it's even dropping while charging. This is strange. If you ruled out any apps or wake locks that might be draining the battery I would buy a good reliable battery. The draining while charging is a red flag. I'd say the battery is going bad. I don't at all regret my purchase of the big battery. It for me, solved my issues. I do Hope this helps and I wish you the best. Hopefully you will get your issue resolved soon.

its either an issue with the battery or the battery reporting.
Only thing you can really try is to charge it up to 100%, wipe battery stats in recovery, then let it empty totally and charge it up again, see how its behaving. There is a chance that its the reporting that is off.
otherwise this looks like the battery is on its way out im afraid

Argh. I hope it's not the replacement battery too. I got a replacement HTC battery. The problem I'm having getting anything useful from Better Battery Stats is that rarely am I off the charger. In the settings it says I can log while charging but it may mess up the stats so I've shied away from doing that. I'm not against getting a bigger, better battery but I would hate to do that and have it actually be something else hardware-wise where I would need to get rid of my phone.

I'll give this a try if I can get it back up to 100%. Is the reporting in Recovery always correct? The battery never has issues charging while it's in Recovery mode. If that's the case then I'll charge it to 100% in recovery and then wipe and start fresh.
Thanks
I don't think it's the battery. This phones have errors in battery readings. I feel your pain man. Mine is from T-Mobile (Sensation 4G) and it discharges if I use it even at lowest brightness when it's charging too.
If I reboot, I get the battery boost. I have tried EVERYTHING I read here and nothing worked. I even have 4 batteries. All of them in good condition.
I even tried three times discharging it fully and without turning it on, charge it in the night and when I wake up 7-8 hours later, it's still charging. I tried wiping stats, changing ROMs, changing the usb cable and the charger. Everything... I believe it's a hardware issue. (Thank HTC for that) I'm not buying another HTC when I have to upgrade.

Interesting...so if you were to charge the phone in recoery how long do you think it would take to get to 100%?
I would definitely do what you said, charge in recovery then wipe battery stats and go from there.
If you're interested in having something to compare to, it takes my phone about 3 hours to charge to 100% (by the way I'm using an Anker extended capacity battery), with a peak current usually around 800 - 900 mA. Fully charged I have somewhere around 4100 mV. If you haven't already, I'd suggest adding a Battery Monitor widget with mA, mV, and % available being displayed and it will be pretty easy to get an idea what's going on.

I'm leaning towards hardware issue too. That's why I figured I'd post and see if there was anything else that I can try. It's also why I don't really want to buy an expensive battery since who knows what it'll fit next. I know what you mean about the reboot battery boost. You can almost gamble and bet on percentages when you reboot. I've seen 50% swings before.

In recovery I would guess that it wont take very long to charge to full. I have battery monitor widget installed and while plugged into the wall with my 1.0A charger, it will typically pull 100-200mA but sometimes it'll spike to 700-900mA. No rhyme or reason. When idling and functioning properly, without a charger plugged in it drops 9-100mA. Sometimes though while charging it'll sit at negative 100-200mA.
HA! Just rebooted my phone and it went from 68% to 100%. So I rebooted into recovery, it also said full so I wiped stats.

I normally get 2 to 3 mA drain with the phone sleeping. When charging you may not necessarily get close to the 1 A current delivery of the charger straight away, typically it will ramp up over time and reach peak charge current as it gets closer to 100%. Once at 100% it wants to just "trickle" charge to maintain 100% charge until the charger is disconnected, so any wakelocks etc. that cause a current drain during that "trickle" charging will actually decrease battery charge until the charger ramps up to compensate for the drain. Random spikes in charging current would suggest a hardware problem where the electronics are struggling to properly govern the charging process, as would a large negative current drain with the charger plugged in. Silly question but what's the actual plug connection to your phone like? Nice and solid, pins all OK?
