So since 2.3.4 has the battery level issue I've been using Battery Calibration to keep track of my battery level. It reads the mV level consistently after a reboot. I know around 4200 is full. Has anyone checked to see what near empty is?
Sent from my Liberated X2!
I can't say for certain but, I do believe my phone auto-shutoff after it went south of 3700mV. So 3700mV is damn close to dead. Don't know what the exact level is though.
Thanks. That's all I needed. I'm going to try to run this thing dead today and see where its at.

3700 is nowhere near empty, the highest shutoff ive seen was st 3475 and ive seen as low as 3250, i use batstat wiget so my mV is always on my home screen
from my finally liberated X2 roaming the north
My battery is at 3629mV now. And the phone hasn't shutoff yet. But what was odd was just as I typing this post, the battery was at 3495mV. Then it jumped up to 3619mV then up to 3629.
EDIT - I guess when I have the LED on, it puts a bit of a load on the battery so now it's reading 3490mV.
Maximum charge on a single cell lithium battery is 4205 mV. The theoretical "dead" is 3189 mV. Therefore 3700 mV should be at 50%.

The last time my phone shut off I had seen my widget reading around 3350 but I wasn't looking at widget when shut off. I was texting and browsing. I am incline to believe it was around 3200 give or take.
Also, assuming voltage decreases linearly with current drain is incorrect.

I'm not sure what you mean by that? Care to elaborate? For my own curiosity
Voltage & current drain don't necessarily parallel each other. They might not be occurring at the same rate at the same time.

Hey guys, I just got my new GS2 this afternoon and i'm enjoying it a lot but there is a HUGE problem: the battery! I've been charging for the last hour or so and the percentage has only gone up by about 10% also, the entire phone is really warm/hot especially for doing simple things such as checking email and browsing android market. I checked the battery usage stats and it says 57% is due to display! This is even though I set the brightness to the lowest possible, turned off auto-rotate, no live wallpapers, no animations, etc.
Has anyone else had this problem/know how to fix this? Thanks a bunch.
Try shutting it off and take the battery out. After it's cooled off some put the battery back in, turn it on, and try charging it again.

Just tried what you said, didn't work: charging for 10 minutes left it still at 67%. I started charging it at around 5pm or so at 28%, and now it's 9pm at 67%....what gives? that's an average of under 10%/hour.....

Sometimes first charges can take awhile. You won't be really able to tell if there's an issues until after a few charge and drain cycles.
Not an answer you're looking for I know. A draw back of a new smart phone.
But keep an eye on the heat. Download a temperature app so you can check to see if it's getting too hot. 50+ celcius is not good. Can damage the battery at those temps.

Thanks for the information, didn't know that the first charge was any different from the other charges. Right now, I have a fan just blowing on my phone so I think the temp should be fine for now
Hi there,
I know the maximum voltage is 4205mV but what is the minimum? When my battery level was at 6, the voltage was ~3,600mv which concerns me because I have a gut instinct that my phone actually has more juice but is miscalibrated towards higher voltages.
I saw the Ultimate Battery Guide and it mentions that before calibration, OP charged to 100% and had ~3,400mV. This means that despite his terrible battery life, he was still able to run his phone at a voltage lower than my lowest - and his was at 100%!
So what voltages are you lot getting when battery life is almost dead?
Any help is highly appreciated.
Thanks!
Wow, it's been 5 months and I forgot about this thread.
So...
BUMP!!!!
Glad u bumped this up I am at 32 percent and have 3792mv still I keep running g it down see what I get

Ok at 4 percent I am at 3490
Sent from my MB860 using xda premium
I've seen voltage readings logged in Battery Monitor Widget as low as 3200 - 3300 mV before the phone shutdown automatically. The low 3400's are probably more common with a percent or two remaining.
I dont know if i just have a bad battery in my phone but ive had it about a week now. No matter how much i use it even if i dont use it at all i can pull it off the charger at 7am and by 1030 or eleven its dead. Ive tried multiple roms to see if it helped but nothing. So my question is do droid x batteries work for this phone too? Ive been searching amazon for extended batteries and it seems like most are for droid x but some say that they are for both. Also does anyone else experince this? With the way the battery is on 2.3.4 i go from full to 15 percent out of nowhere. Im hoping an extened battery will at least allow me to get a full day of work out of it. If someone could link me to a good battery theat they have used that would be great too. Thanks.
Are you heavily calling, texting, gaming, etc during the time your phone's battery is rapidly gaming? Do you have your brightness turned all the way up? Do you allow account synching in the background? All of these are the main causes of battery drain, though they shouldn't drain it quite that quickly. You could very well have a bad battery. Try downloading app/widget battery left, charge up to 100%, and check the voltage on the battery. If less than 4.2 volts, it could mean a battery issue. However even if at 4.2, I can't gaurentee battery health.
Yes, Droid X batteries do in fact work for our phones. I'm actually using the Trident Electra case and battery meant for the X. I highly recommend it, I love the battery life (3 or so days without charging) and the protection the case offers.
Hope I could help!
Yea I hardly use ny phone for calls. And text. Mainly emails and just browsing the forums from time to time. But I manually sync my accounts. Just for this reason. But I have nevr seen anything like this. I have battery minored widget pro voltage is fine the graphs are hilarious to look at since the phone will go from 100 to 93 then drop knew by one to 80 then it drops to 47 and with a half hour of that its at fifteen and as soon as the low battery indicator comes on I hit ok and a minute later its dead.
Well hopefully problem solved ordered a two battery combo with wall charger. 3500mah

Dead like your phone shuts off? Or the phone % tells you its dead? My extended battery has never read correctly, right now its shows 1% at 3.997v thats most of a charge yet

I'm having some problems to. Today was the first day I really kept track of how fast my battery drained itself and my God, I feel like my phone should win an award for most juice lost in 4 hours.
I downloaded Easy Battery Saver from the market and started to use a battery widget to monitor my battey life and it honestly seems like the app is working. Give it a try and see how you like it.

I was under the impression that both the X and the X2 used the same battery (BH5X).
If I am wrong, someone please correct me...
They use the same battery. Have you tried calibrating? Charge to 100% then go to spare parts> battery info> then battery voltage. What is it?
Tapin' the Talk on the xSquared
What frequency do you have your email to check. If you have your email on push then the battery will die a lot faster also. I can kill my battery in 4 hours with non stop use. Orbit baby's it 15 he's has been my best. And yea the x and x2 use same battery my spare is from my Droid x and they are the same part number.
Thanks a lot for all the help guys I got the extended battery which helped a little. But I sold the phone already. Couldn't handle being so restricted.

Ive been using 1800s lately..2 of them that i charge with an external charger that came with them. Usually getting around 18 hrs at normal/heavy use. Considering i was lucky if i ever made it 12 hrs on the stock 1500, it was a good deal.
So both 1800s were dead and the plug in charger wasnt charging for some reason...phone kept restarting.. so i popped in the stock as a last resort and it made it 1 day 13 hrs and might have kept going if i hadnt taken it out at 4%. Really??
What changed it? I had charged it on the external charger and itd been sitting unused for a few weeks. Or does the phone adjust to longer cycle times when using extended batteries?
Ill have repeat the experiment and see if i get the same results.

Some higher power decided you deserved an ungodly amount of battery life considering two 1800's broke on you
I've no idea as to why this would happen. You got quite lucky my freind!
Just to clarify for future reference, battery calibration has never been and never will be relevant in accurate battery readings. It tracks what hardware and software on the phone have used the battery, nothing more.
Anyway, I don't have an answer for you. The fact that you got significantly less battery from your 1800's as opposed to your recent stock battery experience simply doesn't make sense. Could you have been using one of your 1800's and not realized it? I know that sounds silly, but that drastic improvement from a considerably weaker battery is illogical. I think you're missing something.
I could be wrong though, and for your sake I hope I am. I hate the stock battery. It's horrendous. Trident 3800mah ftw!
I am a heavy user most days. I turn the data off most nights and mostly just use wifi at home. I didnt play as many vids or any games that day but none of that matters most of the time. Light or heavy use and i usually get crappy battery life. The 1800s being the exception. Not broke...i just hadnt had time to charge them..the external charger is very slow..im talking 6 or more hrs for a full charge. So honestly no idea how my stock battery outlasted my 1800s... im going to put it on the external charger and try it again next battery change. Couldve been a fluke.

Obvious lack of a read is obvious. Please, do read the entire original post before making a response. It comes across as rude, and is simply not productive. It isn't necessary.
Thanks!
It was definitely the 1500... the batteries look different and the 1500 actually counts down accurately...was nice having that again for a change. The 1800s i have seem more for the atrix than the x2 or theyr from a batch that just dont report accurately. It goes from 99 down to 1% within the first few hrs and then just stays at 1% for the majority of the charge. So i never know when its going to shut off on me.
The 1500 is charging..so ill give it another go whenever the 1800 thats in now dies.

Mine has done that also, more than once. Doesn't seem to effect anything though. Seems to go away after a battery pull. Weird.
It mustve been a fluke. Used the 1500 again and got maybe 16 hrs. Thats still longer than what i usually got out of it when it was my daily. Letting it die completely and then using the external charger does seem to extend the charge cycle a bit..but thats nothing new.

That big drop off at the end always happens to me when I upload a big video to dropbox or I sync my T-backup to dropbox.
I don't have Wifi at home.
I have seen it mentioned in here a couple times now about "letting the battery die completely" don't you all realize how HORRIBLE that is for the life of a Li-on battery?! these batteries were DESIGNED to last longer and stay "healthier" when you plug in when it gets down low on charge (say 15-5% with 5% pushing it cuz its gonna shut off real soon) tho I do understand it's difficult to gauge when to plug in using a 1800mah(aka Bh6x battery) due to inaccurate readings by the system (it's best to use a widget that will show in real time the voltage left and when it gets low throw it in charger).
ALL these battery "calibration" apps& techniques have been lieing, they almost all day to drain battery completely when that's just a bad idea (not to mention "calibration" isn't actually necessary IMO anyways)
sorry, didn't mean to get off topic...

I see those "empty spaces" sometimes as well, usually happens if I have rebooted, pulled battery, gone into BSR , time got screwed up somehow (I set time manually most of time cuz i found using automatic setting seems to make my phone wake up for no apparent reason..if I need to reset time I just check the automatic box for a minute and the time/date goes to what it should be then I uncheck it)
but I haven't exactly pinned down what causes those lines, if I figure it out I'll let ya know

I'm currently getting ridiculous battery drains(like 500 to 980 ma) when my phone isn't plugged in. My phone also gets really hot. This isn't constant but has happed a lot even right after restarting my phone. I have been using Battery Monitor Widget. It might be off or wrong readings but the heat and the speed my battery is draining tell me it isn't.
Details
3.7 volt battery
Drain of 500-900ma when only using 4g no apps open
Clean rom 4.3
Battery usage general show most battery is from display.
Sometime even when it plugged in to a htc usb charger it still has shown around -143 ma.
Any ideas
I'm pretty sure just having 4g on entitles your phone to half of its natural battery life XD
Typically a lot of drain comes from disturbance of deep sleep, I believe there's "wakelock" or something similar on the android market that helps prevent and/or shows what is causing it.
Of course, common issue, hard to say if it isn't something more generic
currently I have it sitting here charging with screen on only as far as I can tell. It for about 10 minutes was telling me it was charging at 32 ma then it went up 205 ma and bounced between that and 105 ma for a bout ten minutes. It went from room tempature to 44.7 degrees celsius.
Now it skipped to -55 ma (while still ac charging) for a few minutes spiked to +653 ma and now is back to 100 ma. That seem to be all over the place and the phone is very warm.
To me that indicates either a problem or a huge drain of power.
Am I just that far off. Has anybody looked at the reading from battery monitor widget or something similair to see what a normal drain is in ma or a normal charge.
maybe an unruley app running in the background? check what's using your battery: settings- > about phone- >battery- > battery use.
It usually shows the majority of the power (50% at least) going to the screen and not much else notable.
Also on a probably unconnected note it produces ridiculous RF interference. But only when charging. At work it was causing crackling in both my desk phone and laptop and when in my dorm it was causing loud cracking in my speakers well over 2 feet away. Is that normal for everyone else.
Start uninstalling or freezing apps that you've installed

This is also my problem. I have been experiencing huge power drain ever since installing the 3.11.605.22 leak. I tried different kernels, rolling back to GB. Went S-off and tried different radios, and then most recently moved up to the new 3.13.605.7 leak, and am currently on CleanROM DE 1.3 and nothing has improved.
Sometimes my mA will go beyond -1000!
Would appreciate any suggestions as I have no clue what to do about it.
I would suggest downloading System Panel from playstore. It shows you what's running and how much power its using from your device.

Copy everything off both cards, format both cards through the phone, internal and external, and then copy everything back.

That didn't do it. Down 12% in an hour with limited use.
Say, anyone else who is getting decent battery times have Battery Monitor Widget and are willing to give us battery-challenged folks an idea for what a typical mA draw range is for your device when you are using it?
I am having the same problem with my phone.. Its gotten a little better since moving to the latest Clean Rom, but if Im actually using the phone (screen on and doing something) the battery plumits. any suggestions would be greatly appreciated.
I bought this phone from someone and didnt get it from Verizon so Im SOL as far as getting them to replace it.
